NOTES
DEPCCFLG: Completion code: coronal caries
This variable was constructed to help the analyst decide whether
or not to include an examinee with incomplete or missing data on
the coronal caries component in the analysis of that component.
Examinees who have no valid or useful data have a completion code
of "3 Not assessed."
DEPCJFLG, DEPCLFLG, DEPGNFLG, DEPLAFLG, DEPPCFLG: Completion codes
These variables were constructed to help the analyst decide whether
or not to include an examinee with incomplete or missing data on
the periodontal component in the analysis of that component. For
examinees who were medically excluded from periodontal components
or who were not in the age range to receive these assessments, the
periodontal component data and the completion code are blank.
Examinees who were completely edentulous or who otherwise have no
valid or useful data have a completion code of "3 Not assessed."
DEPCLFLG: Completion code: calculus
See note for DEPCJFLG.
DEPDQFLG: Completion code: denture questionnaire
This variable was constructed to help the analyst decide whether
or not to include an examinee with incomplete or missing data on
the denture questionnaire in the analysis of that component. For
examinees who were not in the age range to receive these
assessments, the denture questionnaire data and the completion
code are blank.
DEPGNFLG: Completion code: gingival bleeding
See note for DEPCJFLG.
DEPLAFLG: Completion code: loss of attachment
See note for DEPCJFLG.
DEPLQUAD and DEPUQUAD: Upper and lower quadrant periodontal
assessment indicators
The right and left upper and lower quadrant indicators for the
periodontal components were generated by the direct data entry
computer program at the beginning of the examination. Therefore,
indicators may be present for examinees who did not have
measurements or who were edentulous. Note that because the value
for the periodontal component is blank, while the quadrant
indicators remained set, there will be a discrepancy between
these counts.
DEPOVB: Occlusal characteristics: overbite (mm)
Overbite was calculated by subtraction of overlap from crown
height. The exact measurement process is fully described in the
Oral Examination Component manual (U.S. DHHS, 1996b).
DEPPCFLG: Completion code: pocket assessment
See note for DEPCJFLG.
DEPRCFLG: Completion code: restorations and tooth conditions
This variable was constructed to help the analyst decide whether
or not to include an examinee with incomplete or missing data on
the restorations and tooth conditions component in the analysis
of that component. For examinees who were not in the age range
to receive these assessments, the restoration and tooth
conditions data and the completion code are blank. Examinees who
were completely edentulous or who otherwise have no valid or
useful data have a completion code of "3 Not assessed."
DEPRSFLG: Completion code: root caries
This variable was constructed to help the analyst decide whether
or not to include an examinee with incomplete or missing data on
the root caries component in the analysis of that component. For
examinees who were medically excluded from the root caries
component or who were not in the age range to receive the
assessment, the component data and the completion code are blank.
Examinees who were completely edentulous or who otherwise have no
valid or useful data have a completion code of "3 Not assessed."
DEPSE1-DEPSE28: Sealants
The code "2 Not eligible for sealants" was used 1) for certain
teeth not shaped to hold preventive sealants and 2) for missing,
crowned, or filled teeth.
DEPSTCL1, DEPSTCL2, DEPSTCL3, DEPSTCL4, DEPSTCL5, DEPSTCL6:
Oral soft tissue lesions: color
More than one color could be indicated for each lesion. Each
color is a single digit, so multiple digits indicate combinations
of colors. To determine what specific colors were present, one
must separate character strings into their single characters.
DEPSTDX1, DEPSTDX2, DEPSTDX3, DEPSTDX4, DEPSTDX5, DEPSTDX6:
Oral soft tissue lesions: clinical diagnosis
The "unknown" code represents a specific diagnosis of a lesion
that did not fit into any of the named categories. A lesion of
"unknown" diagnosis required a clinical description. The "other"
codes (46 to 59) include identifiable lesions that were different
from soft tissue lesions of interest. During the examination,
the dentist wrote in a diagnosis for lesions designated as
"other." During data processing the 13 most frequently observed
written-in conditions were grouped and coded separately (codes
47-59); the remaining rarer conditions were retained in code 46.
DEPSTLC1, DEPSTLC2, DEPSTLC3, DEPSTLC4, DEPSTLC5, DEPSTLC6:
Oral soft tissue lesions: locations
More than one location could be indicated for each clinical
diagnosis. Multiple locations are shown as combined letters and
numbers. To determine what specific locations were affected, one
must separate character strings into their single characters.
DEPTRFLG: Completion code: traumatic injuries
This variable was constructed to help the analyst decide whether
or not to include an examinee with incomplete or missing data on
the traumatic injuries component in the analysis of that
component. For examinees who were not in the age range to
receive these assessments, the traumatic injuries data and the
completion code are blank. Examinees who were completely
edentulous or who otherwise have no valid or useful data have a
completion code of "3 Not assessed."
DEPUQUAD: Upper quadrant periodontal assessment indicator
See note for DEPLQUAD.
ALLERGY SKIN TEST
Allergy skin reactivity testing was conducted on all examinees aged
6-19 years and on a random half-sample of examinees aged 20-59 years by
a trained examiner in the mobile examination center (MEC).
Before skin testing, screening questions were asked to determine
medical safety exclusions. Those excluded from testing were examinees
who: usually did not have trouble breathing in their chest or lungs
but who were having trouble breathing at the time of the examination
(this trouble was NOT due to nasal congestion from a cold), usually had
trouble breathing in their chest or lungs and had more trouble
breathing at the time of the exam, had a severe response to allergen
skin testing previously, or had severe eczema or infection on both
arms.
Because this examination was administered to a selected subsample in
the examination center, the allergy sample weight (WTPFALG6) should be
used for data analysis. For more information on the use of sample
weights in NHANES III data analysis, refer to the NHANES III Analytic
and Reporting Guidelines (U.S. DHHS, 1996b).
The allergy skin test consisted of the evaluation of immediate
hypersensitivity reactions to any of 10 licensed, commercially
available, FDA-approved, standardized allergens as well as positive
and negative controls. The extracts were indoor allergens
(Dermatophagoides farinae (house mite), cat, German cockroach),
outdoor allergens (short ragweed, perennial rye, Alternaria alternata,
Bermuda grass, Russian thistle, white oak), and a food allergen
(peanut). The positive control was histamine, and the negative control
was the glycerinated diluent. Examiners prepared fresh allergen
solutions upon arrival at each MEC site.
Hypersensitivity reactions were evaluated after administering the
allergens on an examinee's forearms. Allergens were applied using the
prick-puncture technique at 12 skin sites (one for each allergen and
the positive and negative controls) determined by a clear, plastic
template. The flare and wheal areas were delineated with a marking
pen 15 minutes after the skin was punctured and the allergens were
applied.
The length and width of the flare and wheal were measured with a 100-
mm flexible, clear, plastic ruler. Length was defined as the longest
diameter of the reaction, and width was defined as the diameter
perpendicular to the length at its midpoint. If a reaction had any
dimension 3 mm or greater, all four dimensions (length and width of
flare and wheal) were measured and recorded. If all four dimensions
were less than 3 mm, zeroes were recorded for all the measurements.
Confluence was noted for both allergens if two reactions overlapped.
For details of the allergy testing protocol, see the Training Manual
for Allergy Component (U.S. DHHS, 1996b).
The NHANES III allergy skin test was administered by health technicians
who were trained to perform the testing. Training occurred before the
examination period at special training sessions held at NCHS or at the
offices of the contractor responsible for survey operations. The
component was monitored on a regular basis by the component
consultant, and retraining was conducted annually. In addition to
data collection training, the technicians were trained to recognize
and respond to generalized hypersensitivity reactions. A physician
was in the MEC during all examinations, and drugs for treating
systemic allergic reactions were available.
Information on respiratory symptoms related to allergies can be found
in the Household Adult Data File (for examinees aged 17 years and over)
and the Household Youth Data File (for examinees aged 2 months-16
years).
The allergen data fields are blank for examinees who were excluded for
safety reasons. For those examinees who were eligible for the allergy
skin test but for whom allergen data were not collected, the allergen
measurement fields have "888 Blank but applicable" values. In most
cases, these missing data were due to examinees not participating in
the allergy skin test, usually due to time constraints. In other
cases, however, data on some but not all allergens were collected.
These gaps in the data were due to refusals to continue the testing or
to receive specific allergens.
All measurements were taken within the acceptable time of 15 plus or
minus 5 minutes except for one examinee who was measured at 23 minutes
after the administration of the allergens and the controls. Therefore,
the variables indicating the minutes from administration to reading for
each allergen were not included on this data file.
Data processing and editing were performed to ensure internal data
consistency.

NOTES
ALPTECH1 and ALPTECH2: Examiners number 1 and 2
Because of the time interval between allergen placement and
reading, the examiner number was entered twice. Examiner number 1
placed the allergens, and examiner 2 measured the reactions.
AUDIOMETRY
Pure tone air conduction audiometric threshold testing was conducted
on all examinees aged 6-19 years by a trained examiner in a soundproof
room in the mobile examination center (MEC).
Before threshold testing, a screening questionnaire was administered
to determine the need for test exclusions and to assess factors that
might affect test results. Examinees who reported having ear drainage
(AUPA10) were excluded from air conduction testing on the ear(s) with
drainage.
Because this examination was administered in the mobile examination
center, the MEC examination sample weight (WTPFEX6) should be used for
data analysis. For more information on the use of sample weights in
NHANES III data analysis, refer to the NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996b).
Threshold testing was conducted on both ears of examinees at seven
frequencies (500, 1000, 2000, 3000, 4000, 6000, and 8000 Hertz (Hz)).
The valid range for air conduction threshold values was determined by
the effective range of the audiometers (Grason-Stadler, Inc., Model GSI
16, Littleton, MA), which was from -20 to 105 dumbbells (dB). Observed
values were between -10 and 100 dB. If an examinee did not respond to
the signal tone at any level for one or more frequencies and a comment
by the examiner indicated known deafness or severe hearing loss, a
threshold level of 105 dB was entered. In accordance with the testing
protocol, a retest with masking occurred if an examinee had air
conduction threshold value(s) at a given frequency that differed by 40
dB or more between both ears. If the lack of response was unilateral
with a threshold value of 65 dB or lower for the other ear, a threshold
value of 105 dB was entered for the relevant retest with masking
value(s).
Before the examinations began at each MEC site, a field output
calibration check was performed, and an environmental noise survey was
conducted. The audiometer was rechecked weekly, and during
examination periods, the tone quality, masking tone quality, hearing
level controls, and earphones were checked daily. If a unit did not
meet specifications, it was sent for service, and a backup unit was
used for examinations. Additionally, laboratory calibration on each
unit was performed approximately twice a year. For details of these
procedures, analysts should consult the Audiometry and Tympanometry
Manual (U.S. DHHS, 1996b).
Air conduction threshold testing alone is not sufficient to fully
characterize hearing loss; it only provides information on the
severity and the frequencies affected. Because of this, tympanic
membrane compliance also was measured to help determine the nature of
any hearing loss observed in the audiometry data. Analysts should
refer to the Tympanometry section of the Examination Data File for
information on this aspect of hearing testing. In addition, questions
on hearing status including ear infection history and the use of
hearing aids can be found in the Household Youth Data File (2 months-
16 years of age).
The audiometry consultant provided extensive training to examiners at
their time of hire, and each examiner's performance was monitored on a
periodic basis. Audiometry and tympanometry were priority components
at three of four annual MEC team retrainings.
Data processing and editing were performed to ensure internal data
consistency. Notes have been provided for variables requiring
additional explanation.

NOTES
AUPA10: Drainage/discharge from either ear?
Examinees who reported having ear drainage were excluded from air
conduction testing on the ear with drainage and from tympanic
membrane compliance testing on both ears. Threshold value fields
for excluded ears are blank. Tympanometry data fields for
excluded examinees are blank.
AUPA9: Tube in right or left ear?
Examinees who reported having a tube in either or both ears were
excluded from tympanic membrane compliance testing. However, air
conduction threshold testing was performed if there was no report
or evidence of drainage (AUPA10). Tympanometry data fields for
excluded examinees are blank.
AUPAUDO2 and AUPB1C1-AUPB1C8, AUPB2C1-AUPB2C8: Retest information
When examinees had air conduction threshold values at a given
frequency that differed by 40 dB or more between the left and
right ears, the ear with the higher threshold value(s) was
retested while a masking sound was introduced into the other ear.
In cases for which a retest was indicated but for which no retest
data existed, the relevant variables were coded "Blank but
applicable." If no threshold value differences of 40 dB or more
were observed, these variables are blank.
TYMPANOMETRY
Tympanic membrane compliance was tested for all examinees aged 6-19
years by a trained examiner in a soundproof room in the mobile
examination center (MEC).
A screening questionnaire administered before audiometry testing
also determined tympanometry test exclusions and can be used to assess
factors that might have affected tympanometry results. If an examinee
reported that either ear had a tube (AUPA9) or drainage (AUPA10),
tympanometry was not performed, and all tympanometry variables are
blank. Analysts should refer to the Audiometry section of the
examination data file for information on the screening questionnaire.
In addition, questions on hearing status, including ear infection
history and the use of hearing aids, can be found in the Household
Youth Data File (ages 2 months-16 years).
Because this examination was administered in the mobile examination
center, the MEC examination sample weight (WTPFEX6) should be used for
data analysis. For more information on the use of sample weights in
NHANES III data analysis, refer to the NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996b).
The tympanometer (Model TA-7A Automatic Impedance Meter, Teledyne
Avionics, Charlottesville, VA) produced a paper tympanogram output and
was connected to a personal computer for electronic data collection.
Tympanometer function was checked daily. If a unit did not meet
specifications, it was sent for service, and a backup unit was used
for examinations. Laboratory calibration on each unit was performed
approximately twice a year. For details of equipment maintenance
procedures, analysts should consult the Audiometry and Tympanometry
Manual (U.S. DHHS, 1996b).
Training for tympanometry was combined with that for audiometry. At
the time of hire, examiners received extensive instruction from the
audiometry consultant, and the examiners' performance was monitored on
a periodic basis. Hearing evaluation, which included audiometry and
tympanometry, was a priority component at three of four annual MEC
team retrainings.
The variables containing equivalent volume at various pressures
(TYPC000L-TYPC120L, TYPC000R-TYPC120R) can be used to create
tympanogram plots of compliance as a function of pressure. To do so,
the analyst must rearrange the data to have 121 observations per
examinee (one for each pressure value at which compliance was determined
from -400 to 200 daPa in 5 daPa increments) and create a variable to
record the associated pressure values. An example of SAS programming
code to perform this rearrangement is included in the note for
TYPC000L-TYPC120L and TYPC000R-TYPC120R.
This data file includes 242 variables with equivalent volume data for
pressure values between -400 and 200 daPa. Many examinees have data
for pressure values of -200 daPa or greater but have no data (blanks)
for pressure values from -400 to -205 daPa. This is due to
variability in a software setting on the tympanometer that toggled an
option for continuing readings to -400 daPa or stopping the pressure
at -200 daPa if a compliance peak occurred before -175 daPa. There
are data for pressures between -400 and -205 daPa for 1156 left ear
observations and 1166 right ear observations. Of these observations
with data for pressures lower than -200 daPa, only 192 left ear
observations and 200 right ear observations had pressure at peak
compliance values of -175 daPa or lower. When plotting tympanogram
data, analysts may want to include data points for pressure values
between -400 and -205 daPa. However, in most cases, this pressure
range will not add useful tympanogram information.
Early in the survey, electronic data collection was not fully
operational, and sporadic equipment problems led to data loss
throughout the survey. In these cases, the tympanogram data points
(TYPC000L-TYPC120L, TYPC000R-TYPC120R) are not available. However,
the values for peak compliance (TYPCMPLL, TYPCMPLR), pressure at peak
compliance (TYPPRSPL, TYPPRSPR), canal volume (TYPVOLL, TYPVOLR), and
acoustic reflex (TYPRFXL, TYPRFXR) were entered into the data from the
hard copy tympanograms if they were available.
Data processing and editing were performed to ensure internal
consistency of data. Notes have been provided for variables requiring
additional explanation.

TYPC000L-TYPC120L and TYPC000R-TYPC120R: Equivalent volume at various
pressures, left and right ears
Use the following SAS code, or a similar process in another
programming language, to obtain plots of compliance (y) versus
pressure (x) for left and right ear data for each examinee
(identified by SEQN) in a data set. Note that the use of name-
range variable lists in the array statements assumes that the
variables are ordered as shown in the data file code book.
Variations in ordering for the specified variables will result in
errors.

WISC/WRAT COGNITIVE TEST
Cognitive function was evaluated by administering portions of
standardized tests to examinees aged 6-16 years at the time of the
examination. This represents a variation from the usual NHANES test
protocol, in which tests are conducted based on the age at the time of
the household interview, rather than on the age at the time of the MEC
examination. The protocol for this component did not detail any
medical, safety or other exclusions.
Because these tests were administered in the mobile examination center
(MEC), the MEC examination sample weight (WTPFEX6) should be used for
data analysis. For more information on the use of sample weights in
NHANES III data analysis, refer to the NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996b).
Cognitive function was evaluated using parts of two tests, the
Wechsler Intelligence Scale for Children-Revised (WISC-R) and the
Wide Range Achievement Test-Revised (WRAT-R). Two subtests of the
WISC-R test, a verbal component (Digit Span) and a performance exam
(Block Design), were administered and are considered relatively
culturally unbiased (Kaufman, 1979). In addition, two subtests of the
WRAT-R test, math and reading, were conducted. The WISC-R test was
administered first and was followed by the WRAT-R. The scores for all
four subtests used a common scale and were derived for each child
relative to his/her age group based on test-specific standardization
samples created by the test developers (Wechsler, 1974; Jastak, 1984;
Kramer, 1995).
At the time of hire, MEC interviewers were trained to conduct the
WISC/WRAT examination. During annual site visits, test administration
was evaluated, and re-training took place. To increase the number of
evaluated examination administrations with minimum intrusion and after
obtaining informed consent from the examinees or their guardians,
sessions were audio-taped and reviewed for protocol adherence.
Feedback was provided to the interviewers after review of the taped
sessions.
An automated data collection system ensured that responses obtained
were within acceptable ranges. Consequently, minimal data processing
and editing were required. Notes have been provided for standardized
and recoded variables and for variables requiring additional
explanation.
Conducting only a portion of each of the WISC-R and WRAT-R tests with
children in NHANES III limits data interpretation. For example, an
Intelligence Quotient (IQ) cannot be calculated for an individual
using the WISC-R results from NHANES III because only certain subtests
were administered. The complete WISC-R examination is comprised of
twelve components, six verbal and six performance modules. An IQ can be
calculated only when ten of the twelve verbal and performance elements
are administered. Similarly, the WRAT-R test administered in NHANES
III omitted a spelling section and is, therefore, incomplete. For
additional information on the tests, refer to the Manual for the
Wechsler Intelligence Scale for Children-Revised (Wechsler, 1974) and
the Wide Range Achievement Test-Revised Administration Manual (Jastak,
1984).
WISC-R and WRAT-R test forms are not found in either the Plan and
Operation of the Third National Health and Nutrition Examination
Survey, 1988-94, or the test manuals. The forms are copyrighted and
may be reproduced only with written permission from the publishers.
Write to Jastak Associates, Inc. (1526 Gilpin Avenue, Wilmington,
DE 19806) for the WRAT-R test form and to The Psychological
Corporation (555 Academic Court, San Antonio, TX 78204-0952) for
the WISC-R form.

NOTES
WWPBSCSR and WWPDSCSR: Scaled scores
Scaled scores were determined using calculations provided in the
WISC-R Manual (Wechsler, 1974). Refer to this publication for
information on deriving these scores. Scaling scores allows
comparison of WISC-R with WRAT-R test components.
WWPDSCSR: Digit span scaled score
See note for WWPBSCSR.
WWPLANG: Language used in exam
All tests were administered in either English or Spanish.
Children who did not speak either language were excluded from the
test, and their test results were coded as "Blank but
applicable." Note that of the 292 "Blank but applicable" cases
for language used in exam, 280 had all test components "Blank but
applicable" (8-filled).
WWPMRSR: Math raw score
This variable represents the sum of the raw scores for the oral
and written math tests.
WWPMSCSR: Math scaled score
The math scaled score (WWPMSCSR) was derived from the math raw
score (WWPMRSR) using factors calculated and provided in the
WRAT-R Administration Manual (Jastak, 1984). This variable
represents the scaled score for the mathematics test and allows
comparison between the WRAT-R and WISC-R exams.
WWPMSSR and WWPRSSR: Standardized scores
Standardized scores represent an age-standardized version of raw
scores and were calculated according to the WRAT-R Administration
Manual (Jastak, 1984). Refer to this publication for information
on deriving these scores. Note that in accordance with the
WRAT-R manual, the smallest standardized score possible varies by
age.
WWPRRSR: Reading raw score
This variable represents the sum of the raw scores for the oral
and formal reading tests.
WWPRSCSR: Reading scaled score
The reading scaled score (WWPRSCSR) was derived from the reading
raw score (WWPRRSR) using factors calculated and provided in the
WRAT-R Administration Manual (Jastak, 1984). This variable
represents the scaled score for the reading test and allows
comparison between the WRAT-R and WISC-R exams.
WWPRSSR: Reading standardized score
See note for WWPMSSR.
SPIROMETRY
Lung function testing (spirometry) was conducted on examinees aged
eight years and older by a trained technician in the mobile
examination center (MEC). It also was conducted at the home of
examinees aged 60 and over who were unwilling or unable to come to the
MEC. Before testing, screening questions were asked to determine
medical safety exclusions. Those excluded from testing were examinees
who had undergone chest or abdominal surgery within three weeks or had
experienced heart problems (myocardial infarction or heart attack,
angina or chest pain, congestive heart failure) within six weeks before
the MEC exam.
To determine which subjects were home examinees, the DMPSTAT variable
(3=home-examined) should be used. When analyzing data for combined
home-examined and MEC-examined subjects, the combined MEC- plus
home-examined sample weights should be used (WTPFHX6). When using only
MEC items or measures, the MEC examination sample weights should be
used (WTPFEX6). For more information on the use of sample weights in
NHANES III data analysis, refer to the Analytic and Reporting
Guidelines (U.S. DHHS, 1996b).
Spirometry is a widely used test of lung function that measures both
the volume of air in the lung and how quickly a person can move the
air out of the lung. A testing session consisted of repeated forced
vital capacity (FVC) maneuvers. Each maneuver required the examinee
to take the deepest possible breath and exhale into a spirometer as
hard, fast, and completely as possible. The spirometer recorded the
volume of air exhaled as a function of time from which a number of
parameters were measured. Each examinee attempted to perform at least
five FVC maneuvers.
The testing procedure was explained and demonstrated to each examinee
by a spirometry technician. The computer provided immediate feedback
on the examinee's effort, and the technician used that information to
actively coach the examinee through each trial.
For a maneuver to be acceptable, it had to be a maximal exhalation
free from a cough, excessive hesitation, a leak, an obstructed
mouthpiece, variable effort, or early termination. An additional
goal was that the examinee have a sufficient number of trials to
demonstrate that the FVC and forced expiratory volume(FEV1) values were
reproducible.
Aside from using a different type of spirometer flow-type (see
SPPTYPE) in home examinations, technicians used procedures comparable
to those used in the MEC. Therefore, the home spirometry values were
incorporated into the MEC spirometry measures data set. Refer to the
Spirometry Examination Manual (U.S. DHHS, 1996b) and the Home Exam
Manual (U.S. DHHS, 1996b) for descriptions of data collection
procedures and methods. Testing procedures met the recommendations of
the American Thoracic Society (American Thoracic Society, 1987).
The National Institute for Occupational Safety and Health (NIOSH)
served as the spirometry quality control center. Each spirometry
technician received at least one week of formal training and
satisfactorily completed a NIOSH-approved course on spirometry.
Additionally, spirometry data were reviewed by the quality control
center at the completion of each location, and technicians received
continuous feedback on their performance.
Data processing and editing were performed to ensure internal data
consistency. Notes have been provided for variables requiring
additional explanation.

NOTES
SPPEXPIR: Expiratory time of the trial with the largest forced vital
capacity (FVC)(sec)
The time (seconds) it took to reach the largest FVC.
SPPFEF75: Flow at 75% of FVC (ml/second)
This was the flow rate (ml/second) at 75% of the FVC. Values
were obtained from the "best curve" or the curve with the largest
sum of FEV1 plus FVC.
SPPFEV05: Forced expiratory volume (FEV) at 0.5 seconds (ml)
The volume (ml) of air exhaled during the first 0.5 second of a
forced vital capacity maneuver. The volume reported is the
largest volume achieved from all acceptable FVC maneuvers.
SPPFEV1: Forced expiratory volume at 1 second (ml)
The volume (ml) of air exhaled during the first second of a
forced vital capacity maneuver. The volume reported is the
largest volume achieved from all acceptable FVC maneuvers.
SPPFEV3: Forced expiratory volume at 3 seconds (ml)
The volume (ml) of air exhaled during the first three seconds of
a forced vital capacity maneuver. The volume reported is the
largest volume achieved from all acceptable FVC maneuvers.
SPPFEV6: Forced expiratory volume at six seconds (ml)
The volume (ml) of air exhaled during the first six seconds of a
forced vital capacity maneuver. The volume reported is the
largest volume achieved from all acceptable FVC maneuvers.
SPPFVC: Forced vital capacity, largest value (ml)
The total volume (ml) of air exhaled during a forced vital
capacity maneuver. The volume reported is the largest volume
achieved from all acceptable FVC maneuvers.
SPPMANEU: Number of acceptable trials
The number of FVC maneuvers that met the ATS acceptability
criteria.
SPPMMEF: Maximum mid-expiratory flow (ml/second best curve)
The mean forced expiratory flow during the middle half of the FVC
maneuver. Values were obtained from the "best curve" defined as
the curve with the highest sum of FVC and FEV1.
SPPPEAK: Peak expiratory flow (ml/second)
The maximum expiratory flow (ml/sec) observed from all acceptable
FVC maneuvers.
SPPRELIA: Test evaluation
All tests were reviewed by two senior quality technicians at the
spirometry quality control center and classified for reliability.
Tests deemed unreliable should not be used because the quality
technicians determined that the results were of insufficient
quality to be usable.
SPPREPRO: Reproducibility code
In accordance with ATS guidelines, all unacceptable maneuvers
were excluded before the reproducibility calculations were
performed. The goal during test performance was to obtain a
reproducible FVC (largest FVC and second largest FVC within 5%)
and a reproducible FEV1 (largest FEV1 and second largest FEV1
within 5%). The reproducibility code indicates whether a
reproducible FVC and/or FEV1 was obtained.
SPPTEMP: Spirometer internal temperature (Celsius)
This was the internal temperature inside the spirometer measured
at the end of the FVC maneuver.
SPPTRIAL: Number of forced vital capacity (FVC) trials attempted
This was the total number of forced vital capacity maneuvers
attempted by the sample person.
SPPTYPE: Spirometer type
Four different types of spirometers were used; one type was used
in MEC spirometry exams, and three different types were used in
home spirometry exams. The MEC spirometers (type=1) were
customized, Ohio 822 or 827, dry, rolling-seal spirometers and
were interfaced to a microcomputer. For home spirometry, the
three types of flow spirometers used were: MultiSpiro (type=2),
Riko model AS-600 (type=3), and NIOSH (type=4). The MultiSpiro-
and Riko-brand spirometers produced paper tracings with digital
readings of FVC and FEV1. These spirometers provided neither
quality assessments of the subject's effort nor some of the
spirometry variables measured in the MEC. The NIOSH flow
spirometer measured all of the parameters measured by the MEC
spirometer and provided a display of the subject's flow-volume
curve with a computer-determined quality assessment equivalent to
the assessment provided by the spirometer used in the MEC.
MEC YOUTH QUESTIONNAIRE (Except DIS)
The MEC Youth Questionnaire was administered to examinees aged 8-16
years in the mobile examination center (MEC). Conducted by a trained
interviewer, the automated questionnaire was administered in a private
setting to ensure confidentiality due to the sensitive nature of some
of the sections. The questionnaire included sections on physical
activity, tobacco use, reproductive health, selected conditions,
medicine/vitamin usage, food frequency, alcohol/drug use, and the
Diagnostic Interview Schedule (DIS). Because this component was
administered in the examination center, the MEC examination sample
weight (WTPFEX6) should be used for data analysis. For more
information on the use of sample weights in NHANES III data analysis,
refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS,
1996b).
Several portions of the questionnaire were asked only of specific age
or gender groups, and check items are included as variables in this
file to indicate these subgroups. For example, reproductive health
was asked of boys aged 15-16 years and girls aged 10-16 years.
Medicine/vitamin use, food frequency, and alcohol/drug use were
asked of boys and girls aged 12-16 years. The DIS was asked of
adolescents aged 15-16 years. The DIS was edited and documented
separately (see Diagnostic Interview Schedule).
A subset of questions from the MEC Youth Questionnaire were
administered as the MEC Proxy Questionnaire to the parents or
guardians of children aged 2 months-11 years. Questions on medicine,
vitamin, and mineral usage, selected health conditions, and WIC
program participation from the two questionnaires can be combined
for an analysis of youths 2 months-16 years of age (see MEC Proxy
Questionnaire).
Data processing and editing were performed for consistency of
responses within the sections of the questionnaire. Notes have been
provided for variables that were standardized or recoded or those
that require additional comments. The notes reference the questions, by
section and number, from the questionnaires which can be found in the
Plan and Operation of the National Health and Nutrition Examination
Survey, 1988-1994 (NCHS, 1994; U.S. DHHS, 1996b).

NOTES
MYPB6R: Number of cigarettes smoked per day
This variable was created from the question B6. The actual
number of cigarettes smoked per day and a range of cigarettes
smoked per day were the allowable answers. The variable includes
the mean number of cigarettes smoked per day derived from the
range as well as the actual number of cigarettes smoked per day.
MYPB7R: Years smoked this amount in MYPB6R
This variable was created from the question B7 when the data were
not missing. If B7 was missing, this variable used the estimated
number of years the respondent smoked the amount reported in B6.
The number was derived by subtracting the age that the respondent
started smoking regularly from the age at the MEC interview.
MYPB9S: Number of cigarettes per day when smoked the most
This variable was created from the two-part question (quantity
and unit) B9 using the conversion factor 20 cigarettes/pack.
MYPB13S: Number of cigarettes per day usually smoked when youth
smoked regularly
This variable was created from the two-part question (quantity
and unit) B13 using the conversion factor 20 cigarettes/pack.
MYPB21AS: Number of containers of chewing tobacco used per week
This variable was created from the two-part question (quantity
and unit) B21 using the conversion factor seven containers/week.
MYPB21CS: Number of containers of snuff used per week
This variable was created from the two-part question (quantity
and unit) B21 using the conversion factor seven containers/week.
MYPC7S: Months since stopped taking birth control pills
This variable was created from the two-part question (quantity
and unit) C7 using the conversion factor 12 months/year.
MYPC8S: Total number of months took birth control pills
This variable was created from the two-part question (quantity
and unit) C8 using the conversion factor 12 months/year.
MYPC9R: Birth control pills codes
This recode was derived to include a listing of all birth control
pills that were specified in question C9. It includes both birth
control pills with original codes from the chart that the
respondents were shown as well as those that were not included on
the chart but that were specified by the respondents. See the
Appendix in the MEC Adult Questionnaire for the code listing.
MYPC13R: Age at time of first live birth
Question C13 (age at time of first live birth) was only asked of
women who had more than one live birth. To prevent redundant
questions, women who had one live birth were only asked question
C14, "Age at the time of the last live birth." This variable,
MYPC13R, was created to include responses for women who had only
one live birth and women who had multiple births. For women who
had only one live birth, their responses to question C14 were coded
into MYPC13R. For women who had multiple births, their responses
to question C13 were coded into MYPC13R.
MYPC23S: Number of months received WIC benefits
This variable was created from the two-part question (quantity
and unit) C23 using the conversion factor 12 months/year.
MYPC27R: Ever had sexual intercourse
This variable was derived from questions C10 and C27.
Respondents who reported a pregnancy (question C10) were not
asked whether they had ever had sexual intercourse (question C27)
as the response was implicit. Therefore, MYPC27R was coded as
"Yes" for respondents who reported a pregnancy in C10 and coded as
the response in C27 for all other respondents.
MYPC28: Age at first sexual intercourse
The question did not ask about first consensual sexual experience.
Therefore, responses of first intercourse at very young ages were
retained after reviewing comments made during the interview (e.g.,
reports of rape or incest).
MYPF3S: Number of days drank alcohol in past year
This variable was created from the two-part question (quantity
and unit) F3 using the conversion factors 7 days/week, 30.4 days/
month, and 365 days/year.
MYPF5S: Number of days drank nine or more drinks of alcohol in
past year
This variable was created from the two-part question (quantity
and unit) F5 using the conversion factors 7 days/week, 30.4
days/month, and 365 days/year.
MYPF6S: Number of days drank five or more drinks of alcohol in
past year
This variable was created from the two-part question (quantity
and unit) F6 using the conversion factors 7 days/week, 30.4
days/month, and 365 days/year.
DIETARY FOOD FREQUENCY QUESTIONNAIRE (AGES 12-16 YEARS)
The Dietary Food Frequency questionnaire was administered to youths aged
12-16 years in the mobile examination center (MEC). Respondents were
asked how often over the past month they had eaten specified food items.
The foods were listed in groups, targeting those high in vitamins A and
C and calcium. Respondents reported their consumption as the number of
times per day, per week, per month, or never. It is important to note
that portion sizes were not defined, and responses represent "number or
times" as determined by the respondent.
The questionnaire was identical to the food frequency section of the
Household Adult Questionnaire administered to adults aged 17 years and
above (see Adult Household Data File). MEC examination weights
(WTPFEX6) should be used for analysis of the youth Dietary Food
Frequency (Ages 12-16 years). The interview weights (WTPFQX6), however,
should be used when analyzing the adult food frequency data. For more
information on the use of sample weights in NHANES III data analysis,
refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS,
1996b).
Data processing and editing were performed for consistency of
responses within the sections of the questionnaire. As part of the
editing process, the frequency of consumption of food items was
standardized to the number of times consumed per month. Notes have been
provided for variables that were standardized or recoded or that require
additional comments.

NOTES
FFPA1S, FFP1BS, FFP1ES-FFP7CS, FFP8AS, FFP8BS: Frequency of consumption
of food item per month
The frequency of consumption variables were standardized as "times
per month" using the conversion factors 4.3 weeks/month and 30.4
days/month rounded to the nearest whole number. If the frequency
of consumption was reported as "never," the value was recorded as
zero.
FFP1D1: Usual type of milk consumed
Only usual milk consumed was recorded here. If more than one milk
type was reported as "usual," the first milk reported was recorded.
Guidelines based on fat content were developed in order to recode
other milks that were reported but not listed and to create new
categories.
Codes/recodes Reported usual milk
01 (whole/regular milk) goat's milk
02 (2%/low fat)
03 (1% milk) acidophilus milk; lactose-reduced milk
04 (skim/nonfat milk) hot chocolate mix; powdered milk; 0.5%
milk
05 (buttermilk)
06 (evaporated)
07 (other not specified)
11 half and half/cream
FFP8AFC: New codes for other foods not listed
Respondents also were asked about other foods not listed in the
food frequency questionnaire. Responses to this question from both
the adult and the youth food frequency questionnaires were edited
by first determining whether the food could be coded back into an
existing category. When possible, the frequency of consumption of
that food was added to the original response for the pre-existing
category. If the original response was "Never consumed," then the
consumption frequency for the "Other food not listed" replaced the
original response. Foods that were reported using frequency units
were first converted to a common unit; the frequencies were summed
to produce whole number estimates. For example, if the reported
frequency for the category "Other vegetables" was once per day and
asparagus consumption once per week was reported for "other food
not listed," then the frequency for asparagus consumption was added
to the frequency of the "Other vegetables" category and
recalculated as a consumption of eight per week. When it was not
possible to recode a response, a determination was made about
whether a new category should be created based on the reported
frequency of the food or whether the food represented an important
source of a specific nutrient. The following eight new food groups
were defined:
01 Egg substitutes
02 Decaffeinated coffee and espresso
03 Decaffeinated/herbal tea
04 Sports drinks, fruit drinks (excluding juices but including
tamarind drinks), and popsicles
05 Water, including tap, mineral, spring, seltzer, soda
06 Soy products, including tofu, soy milk, soy ice cream, soy
cheese, soy hamburgers, soy hot dogs, soy flour, and textured
vegetable protein
07 Non-alcoholic beer/wine
08 Others not specified or not elsewhere classified, including
diet, breakfast, and nutrition drinks, pudding, condiments,
sour or whipped cream, granola bars, and gelatin
DIAGNOSTIC INTERVIEW SCHEDULE (DIS)
The mental health component of NHANES III included the depression
and mania modules from the Diagnostic Interview Schedule (DIS)
originally developed for the National Institute of Mental Health
(NIMH) Epidemiologic Catchment Area (ECA) program. Trained
interviewers administered the NHANES III DIS questions in the
MEC, using automated data entry, as part of the MEC Youth
Questionnaire for examinees 15-16 years of age and as part of the
MEC Adult Questionnaire for examinees 17-39 years of age. The
data from the DIS permit diagnoses based on the third edition of
the Diagnostic and Statistical Manual of Mental Disorders (DSM-
III).
The final MEC examination weight (MTPFEX6) should be used for analysis
of the questionnaires and measurements administered in the MEC, as well
as for a combined analysis of measurements from the MEC examinations and
associated medical history questions from the household interview. The
household questionnaire data files include information on survey design
and basic demographic variables which may be linked to the examination
data file by using the unique survey participant identifier SEQN. For
more information on the use of sample weights in NHANES III data
analysis, refer to the NHANES III Analytic and Reporting Guidelines
(U.S. DHHS, 1996b).
The DIS is a complicated questionnaire with a number of parallel
series of questions and many skip instructions. The notes below
describe these question series and skip patterns, and analysts
are instructed to carefully read these notes in their entirety in
order to facilitate analysis of this data. The Plan and Operation of
the Third National Health and Nutrition Examination Survey, 1988-94,
page 362, (NCHS, 1994; U.S. DHHS, 1996b) contains a flow chart of the
probe questions and skips from the DIS.
All variable names in the DIS portion of the MEC interviews start
with the prefix MQP. The M indicates that it came from the MEC
interview, the Q indicates that the data transcend the boundaries
of separate adult (A) and youth (Y) interviews (sample persons
ranged from ages 15-39) and the P indicates the data came from
the primary interview.
Any sample person who was age 15 to 39 was eligible to receive
this section of the adult or youth MEC questionnaire. A sample
person who was not eligible to receive this section of the
questionnaire will have all blanks in this section. Note that
selected questions may be blank in the DIS section if the
question was not applicable for the sample person to answer
because of answers they had given to other questions. Also note
that many of the questions have combined the "Don't know" and
"No" category into a single response and this combination will
vary per question in the DIS section.
Approximately 3.7% (322/8773) of the NHANES III sample did not
have valid depression and mania sections of the questionnaire,
with an additional 18 or 0.2% missing all or part of one section
or the other. The major reasons for these missing data are that
respondents: 1) ran out of time, 2) felt the material was too
sensitive, usually because they were using an interpreter, 3) had
comprehension problems due to cognitive impairment, 4) primary
language was not English or Spanish, or 5) refused to answer or
were not asked critical questions. All of the questions for
these sample persons were coded "Blank but applicable."

NOTES
MQPDLANG: Language used to conduct DIS
MQPDLANG is the language in which the DIS portion of the
interview was conducted and it is exactly the same as
MQPLANG (the language of the MEC interview) except when a
comment indicated that the DIS portion of the interview had
been conducted in Spanish. There were 41 adults and 32
youth where this change was made in the study. Most
Hispanic youth spoke English fluently enough that a Spanish
translation was not necessary, therefore, no computerized
version of the youth interview was available in Spanish. It
was only given on hard copy. MQPDLANG was set to 4, Spanish
Youth, only if the variable DMAETHNR was greater than or
equal to 3 and MQPLANG was equal to 3, and the examination was
given on hard copy (MQPHCFLG=1) or a specific comment was
made that indicates the interview was given in Spanish.
MQPDPFLG, MQPMNFLG: Depression and mania completeness flags
When a code of "1" is given to the depression (MQPDPFLG) or
mania (MQPMNFLG) completeness flag, the respondent only
answered the lifetime symptom questions (16 for depression
and 9 for mania) and any appropriate probe questions. It
was then determined in MQPG21, a check item, that there were
not enough positive symptom groups to continue asking
questions (MQPG21=3 or MQPG50=3 for depression and mania,
respectively). The diagnosis of major depressive episode
(MQPDEP) or manic episode (MQPMANIA), respectively, is set
to "No."
When a code of "2" is given to the depression (MQPDPFLG) or mania
(MQPMNFLG) completeness flag, the respondent answered not only the
lifetime symptom questions (16 for depression and 9 for mania) and
any appropriate probe questions but also one or more of the
questions concerning clustering of the positive symptom groups.
These sample persons can skip out of the section at several
different points, but they never answer questions past MQPG26 or
MQPG55, respectively, and they cannot have a positive diagnosis for
major depressive episode (MQPDEP) or manic episode (MQPMANIA).
The diagnosis of major depressive episode or manic episode,
respectively, is set to "No."
When a code of "3" is given to the depression (MQPDPFLG)
or mania (MQPMNFLG) completeness flag, the respondent
answered not only the lifetime symptom questions (16 for
depression and 9 for mania) and any appropriate probe
questions but also all the questions concerning clustering
of the positive symptom groups and the worst episode. These
sample persons should have answers to all questions in their
respective sections and have the chance for a positive
diagnosis for major depressive episode (MQPDEP) or manic
episode (MQPMANIA). The diagnosis of major depressive
episode ranges from 1-5 and the diagnosis of manic episode
ranges from 1-3.
When a code of "4" is given, the lifetime symptoms were
completed and the sample person met criteria to continue
answering questions (MQPG21=1 or 2), but the remaining
section of questions needed to make a diagnosis were not
ascertained (blank, but applicable) or were all answered
"don't know." This is not the same as MQPG21=3 or
MQPDPFLG=1 where sample persons only answered the lifetime
symptom questions because they did not have enough positive
symptoms to qualify to answer the remaining questions.
When a code of "5" is given, the depression and/or mania
section should have been given, but was not, so all fields
are filled with 8's (blank but applicable).
Lastly, a blank in this field indicates the sample person
was not in the acceptable age range and was not eligible for
the depression or mania questions.
In short, the flags divide the data into five groups:
1. Lifetime symptoms answered, insufficient number positive to
ask clustering questions
2. Sufficient lifetime symptoms present but do not
cluster in spells of sufficient duration
3. Sufficient lifetime symptoms present and cluster
in spells of sufficient duration, and may or may
not meet criteria for positive diagnosis
4. Sufficient lifetime symptoms present but no
information available if cluster in spells of
sufficient duration - missing diagnosis
5. No information available, but should have been
collected - missing diagnosis
Blank values appear where the DIS not applicable.
MQPHCFLG: Hard copy flag
Although in almost all circumstances the DIS section of the
interview was given using the computerized version, there
were certain situations where a paper copy was used. This
would occur only when there was a computer failure or for
youth who required a Spanish version. These interviews are
considered valid, but responses to probe questions were not
recorded, and are therefore set to 8's (blank but
applicable).
MQPG0501-MQPG1301, MQPG05L-MQPG12L, MQPG1501-MQPG1601,
MQPG14L-MQPG20L: Lifetime symptoms of depression
The questionnaire inquires whether a symptom has occurred at
any time in life (G5-G20). Each of these DIS symptom
questions can take a value of "1-4." The value "2" means
the respondent said "No" or "Don't know." If the respondent
said "Yes," additional "probe" questions were asked. First,
the respondent was asked if they told a doctor about the
symptom. The answer to this probe question is included
after each respective lifetime symptom. When the interview
was given on hard copy (i.e., not by computer - See
MQPHCFLG, a flag for hard copy), no probe questions were
recorded so the probe questions are filled with 8's (blank
but applicable).
The respondent was then asked if the symptom was always due
to a physical illness or injury (this included pregnancy).
If the respondent said "Yes," then a "4" was coded. If the
respondent said "No," then he/she was next asked whether the
symptom always occurred when he/she used medicine, alcohol,
or drugs. If the respondent said "Yes," then a "3" was
coded. If the respondent said "No," then a "1" was coded.
A value of "1" indicates that the possibility of this being
a symptom of a mental disorder cannot be ruled out.
Additional probes were asked for G13. (See notes for
MQPG1302-MQPG1304.)
As a word of caution, in the Spanish version of question G8,
"Have you ever had a period of two weeks or more when you
had trouble falling asleep, staying asleep, or with waking
up too early?," the phrase used for "falling asleep" really
meant "staying asleep" rather than what was intended. Still
another phrase was used for the part of the question
"staying asleep." Consequently, "staying asleep" was well
covered and "falling asleep" was not. There is no way to
tell to what extent this affected the number of positive
responses.
MQPDGP1L-MQPDGP8L: Summary questions
The lifetime depressive symptom questions (G5-G20) are
arranged in eight groups, each of which approximates one of
the diagnostic criteria in Section B of the definition of a
major depressive episode from the American Psychiatric
Association's Diagnostic and Statistical Manual, Third
Edition (DSM-III).
MQPDGP1L- MQPDGP8L are the eight summary variables which
indicate the number of positive (1's) lifetime symptoms in
each of the respective groups.
MQPG13L, MQPG1302-MQPG1304: Decreased interest in sex
If the respondent answered "Yes" to the initial question
(G13: decreased interest in sex), a series of additional
questions was asked (MQPG1302- MQPG1304). If the respondent
answered "No" to all three questions, then a code "6" (yes,
but wasn't bothered) was entered for G13, indicating that
the symptom was below the diagnostic threshold. If the
respondent answered "Yes" to any one of these three
additional questions, then the normal "probe" questions were
asked, leading to an assignment of values 1, 3, 4, that is,
whether the symptom was always due to physical illness or
injury or medicine, alcohol, or drugs; any remaining parts
of MQPG1302-MQPG1304 were skipped after a "Yes" response to
any one of the probes.
If the respondent volunteered that he/she had never been
interested in sex, the value "5" (no interest ever) was
coded.
MQPG21-MQPG25: Depression module decision points
Item G21 asks the interviewer whether three or more summary
groups of the possible eight had at least one "Yes" response
coded. If there were fewer than three, all the remaining
DIS depression questions were skipped and the interviewer
moved to the mania questions (G41-G49).
If a respondent had three or more DSM-III symptoms during
his/her life (G21), the interviewer asked one of two
parallel series of questions to determine whether questions
pertaining to the worst depressive episode should be asked.
The series of questions are explained below:
Series A, Questions G22, G23, and G26: G21 was coded "1" if
there were three or more depressive symptoms and the
respondent answered "Yes" to the initial question (G2) about
two weeks or more of feeling sad, blue, or depressed. The
respondent was then asked G22 about having these problems
cluster in time, in the same month. If the answer was
"Yes," G26 was asked. If the response to G22 was "No"
(meaning the problems did not cluster in the same month),
then a second question about temporal clustering was asked
(G23). If the respondent again denied having problems
cluster ("Yes, never been a period"), the remaining
depression questions were skipped and the interviewer moved
on to the mania questions. If the respondent said "No, has
been a period" to G23, then G26 was asked.
Series B Questions G24, G25, and G26: G21 was coded "2" if
there were three or more depressive symptoms and the
respondent answered "No" to the initial question (G2) about
ever having had two weeks or more of feeling sad, blue, or
depressed. G24 was then asked to determine if several of
the depressive symptoms (G5-G20) were clustered together in
the same month. If the answer to this was "No," then the
remaining DIS depression questions were skipped and the
interviewer moved on to the mania questions. If the answer
was "Yes" then G25 was asked, which elicits symptoms of
"masked depression." If the respondent indicated that
he/she felt "low, gloomy, blue, or uninterested" then he/she
was asked G26. If the respondent indicated that he/she felt
"okay," the remaining DIS depression questions were skipped
and the interviewer moved on to the mania questions.
MQPG05W-MQPG20W: Worst episode depressive symptoms
These questions ask about symptoms during the worst episode
identified in G40. Each of the questions about a worst
depressive episode is parallel to one of the lifetime
depression questions: for example, MQPG05L asks "has there
ever been a period of two weeks or longer when you lost your
appetite?" The corresponding worst episode question,
MQPG05W, asks, "Did you lose your appetite?" The worst
episode question (in this example, MQPG05W) was only asked
if the corresponding lifetime question (in this example,
MQPG05L) was coded "1." The worst episode question was
coded "Yes" or "No," indicating the presence or absence of
the symptom during the worst depressive episode. A
diagnosis of major depressive episode was based on the
symptoms during the worst depressive episode
(MQPG05W-MQPG20W) which are transformed into eight DSM-III
symptom groups (MQPDGP1W-MQPDGP8W), and is not based on the
lifetime depressive symptoms (MQPG05L-MQPG20L).
MQPG41L-MQPG49L: Lifetime symptoms of mania
The questionnaire inquires about whether a symptom has
occurred at any time in life (G41-G49). Each of these
(DIS) symptom questions can take a value of "1-3." The
value "2" means the respondent said "No" or "don't know."
If the respondent said "Yes," two additional "probe"
questions were asked. The respondent was asked whether the
symptom ever occurred when he/she used medicine, alcohol, or
drugs. If the respondent said "Yes," then he/she was next
asked whether the symptom always occurred when he/she used
medicine, alcohol, or drugs. If the respondent said "Yes,"
then a "3" was coded. If the respondent said "No" to
either question, than a "1" was coded. A value of "1"
indicates that the possibility of this being a symptom of a
mental disorder cannot be ruled out. When the interview was
given on hard copy (i.e., not by computer - See MQPHCFLG, a
flag for hard copy), responses to probe questions were not
recorded so the probe questions are filled with 8's (blank
but applicable).
MQPG47EX: Examples of special gift or power
If the respondent answered "Yes" to G47L, possessing a
special gift or power, they were asked for an example.
Since a high percentage of the examples given had to do with
extra sensory perception (ESP), it was decided to code these
examples into two categories, ESP and other. There were not
enough examples with similar characteristics to code any
other group.
The query regarding special gifts or powers is intended to
elicit reports of beliefs about the self which are psychotic
in nature. If the example did not meet this precept, the
symptom (MQPG47L) was coded "No" and the example deleted.
MQPG50-MQPG54: Mania module decision points
Item G50 asks the interviewer whether two or more lifetime
symptoms of the possible eight (MQPG42L- MQPG49L) had at
least one response of "1" coded. If there was a "Yes"
response of one or less lifetime symptoms, all the remaining
mania questions were skipped and the interviewer moved to
the next section. The remaining DIS questions were coded as
blank.
If a respondent had two or more DSM-III symptoms during
his/her life, the interviewer asked one of three parallel
series of questions to determine whether questions
pertaining to the worst episode of mania should be asked or
possibly skipped to the next section. The three series are
explained below:
Series A, Questions G51, G52, and G55: G50 was coded "1" if
there were two or more symptoms of mania and the respondent
answered "Yes" to the initial question (G41) about one week
or more of feeling high or manic. The respondent was then
asked G51 about having these problems cluster in time, in
the same month. If the answer was "Yes," G55 was asked. If
the response to G51 was "No" (meaning the problems did not
cluster in the same month), then a second question about
temporal clustering was asked (G52). If the respondent
again denied having problems cluster ("Yes, never been a
period"), the remaining mania questions were skipped and the
interviewer moved on to the next section. If the respondent
said "No, has been a period" to G52, G55 was asked.
Series B, Questions G53-G55: G50 was coded "2" if there
were three or more symptoms of mania and the respondent
answered "No" or "Always due to medication/drugs/alcohol" to
the initial question (G41) about ever having had one week or
more of feeling high or manic. G53 was then asked to
determine if several of the depressive symptoms (G42-G49)
were clustered together in the same month. If the answer to
this was "No," then the remaining DIS mania questions were
skipped and the interviewer moved on to the next section.
If the answer was "Yes" then G54 was asked, which elicits
symptoms of irritable mood. If the respondent indicated
that he/she felt "unusually irritable or likely to fight or
argue" then he/she was asked G55. If the respondent
indicated that he/she never felt irritable, the remaining
DIS mania questions were skipped and the interviewer moved
on to the next section.
Series C: G50 was coded "3" if: 1) there were only two
symptoms of mania coded "1" and the respondent answered "No"
or "Always due to medication/drugs/alcohol" to the initial
question (G41) about ever having had one week or more of
feeling high or manic, i.e., responses "2" or "3;" or,
2)there was only one or less symptoms of mania coded "1."
With these combinations, the remaining DIS mania questions
were skipped and the interviewer moved on to the next
section.
MQPG42W-MQPG49W: Worst episode symptoms of mania
These questions ask about symptoms during the worst episode
of mania identified in G66. Each of the questions about a
worst episode of mania is parallel to one of the lifetime
mania questions: for example, MQPG42L asks "has there ever
been a period of a week or more when you were so much more
active than usual that you or your family or friends were
concerned about it?" The corresponding worst episode
question, MQPG42W, asks, "Were you so much more active than
usual that you or your family or friends were concerned
about it?" The worst episode question (in this example,
MQPG42W) was only asked if the corresponding lifetime
question (in this example, MQPG42L) was coded "1." The
worst episode question was coded "Yes" or "No," indicating
the presence or absence of the symptom during the worst
episode of mania. A diagnosis of manic episode was based
on the symptoms during the worst episode of mania MQPG42W-
MQPG49W) which were transformed into seven DSM-III symptom
groups (MQPMNG1W-MQPMNG7W), and is not based on the lifetime
symptoms of mania (MQPG42L- MQPG49L).
MQPDGP1W-MQPDGP8W, MQPDYSFR, MQPDEP: The diagnostic variable
"MQPDEP"
The variable MQPDEP indicates the diagnosis of major
depressive episode which is based on Criteria A and B of the
DSM-III definition of major depressive episode. Criteria C
and D were not assessed, and E was only assessed for
bereavement. The minimum severity requirement is that these
symptoms cause help-seeking or subjective impairment (at
least one "Yes" to G28-G31).
Criterion A for the diagnosis of major depressive episode in
DSM- III calls for "dysphoric mood or loss of interest or
pleasure in all or almost all usual activities and
pastimes." If the respondent said "Yes" to the initial
depression question (G2), or if there were at least two
weeks of dysphoria combined with some other problems (G26),
then the person was said to have "dysphoria," and was
considered to have met Criterion A for the diagnosis of
major depressive episode (MQPDYSFR=1).
The DSM-III definition of Criterion B for major depressive
episode contains eight symptoms, at least four (4 <=MQPDGPSW
<= 8) of which must be present during a depressive episode
in order to qualify for a diagnosis. These eight symptoms
are approximated by the following NHANES III questions
(Note that the DSM-III Symptoms are given in the order that
they are asked in the DIS, rather than the order in the
DSM-III Manual):
DSM-III Symptom NHANES III Questions
1. Appetite or weight change G05W, G06W, or G07W
2. Insomnia or hypersomnia G08W or G09W
3. Loss or energy, fatigue G10W
4. Agitation or retardation G11W or G12W
5. Loss of interest in sex G13W
6. Feeling worthless or guilty G14W
7. Trouble thinking, concentrating G15W or G16W
8. Thoughts of death or suicide G17W, G18W, G19W, or
G20W
MQPDGP1W-MQPDGP8W give the number of positive items per
group for the eight corresponding groups above.
Criterion "E" is only assessed by the absence of
uncomplicated bereavement as the cause of depression, i.e.,
depressed spells were never due to the death of someone
close to the respondent or they may have been caused by
things other than death (MQPG34 = 2).
The variable MQPDEP can take seven values:
1 No diagnosis
2 Major depressive episode without severity
3 Major depressive episode with severity
4 Severe bereavement
5 Non-severe bereavement
88 Blank but applicable
Blank
MQPDEP = 1. No major depressive episode was diagnosed if
the respondent answered sufficient questions so that
Criteria A and B could be determined and did not qualify for
a diagnosis of major depressive episode or bereavement (as
defined below).
MQPDEP = 2. Major depressive episode without severity was
diagnosed if Criteria A, B and E were met but without
severity (all no's for G28-G31).
MQPDEP = 3. Major depressive episode with severity was
diagnosed if Criteria A, B, and E were met plus severity (at
least one "Yes" to G28-G31).
MQPDEP = 4. Severe bereavement meets Criteria A and B plus
severity (i.e., MQPDEP=3), but depressed spells ONLY due to
death of someone close (MQPG34=1).
MQPDEP = 5. Non-severe bereavement meets Criteria A and B
but not severity (i.e., MQPDEP=2), but depressed spells ONLY
due to death of someone close (MQPG34=1).
MQPDEP = 88. The major depressive episode variable was
coded a "Blank but applicable" value if the respondent did
not answer sufficient questions so that Criteria A and B
could be determined. The respondent must answer the initial
depression question (MQPG02) and at least 11 of the lifetime
symptom questions (MQPG05L-MQPG20L) as well as the appropriate
worst episode symptom questions (MQPG05W-MQPG20W).
MQPDEP = Blank. The major depressive episode variable was
coded a "Blank" if the sample person was not eligible to
receive the depression questions.
MQPDPSX1-MQPDPSX2, MQPDGPSW: Total depressive symptom group
counts
The two variables MQPDGPSW and MQPDPSX2 report the total
number of positive depressive symptom groups in the worst
episode (sum of all groups where MQPDGP1W to MQPDGP8W
contained at least one positive symptom) and lifetime (sum
of all groups where MQPDGP1L to MQPDGP8L contained at least
one positive symptom), respectively. The latter also adds
dysphoria (MQPDYSFR=1). These variables range from 0-8 and
0-9, respectively. MQPDGPSW is used in determining the
diagnosis of major depressive episode and MQPDPSX2 is used
in the total symptom count.
The variable MQPDPSX1 reports the total number of positive
symptoms in the worst episode (sum of MQPDGP1W to MQPDGP8W)
plus dysphoria (MQPDYSFR=1) with a range of 0-17. (Note that
this variable is a sum of positive symptoms, not positive
symptom groups.)
MQPFDDP, MQPLDDP: Age of first and last depressive symptoms
The two variables MQPFDDP and MQPLDDP code the age of the
respondent the first and last time, respectively, he/she
experienced depressive symptoms if he/she ever met criteria
for any major depressive episode (2 <= MQPDEP <= 5).
MQPFDDP uses the age in MQPG32 and MQPLDDP combine the age
and time frame information in MQPG35, MQPG36 and MQPG37.
MQPMNGP1-MQPNMGP7, MQPEUFOR, MQPMANIA: The diagnostic variable
"MQPMANIA"
The variable MQPMANIA indicates the diagnosis of manic
episode which is based on Criteria A and B of the DSM-III
definition of manic episode. Criteria C, D and E were not
assessed. The minimum severity requirement is that these
symptoms cause help-seeking or subjective impairment (at
least one "Yes" in MQPG57-MQPG60).
Criterion A for the diagnosis of manic episode in DSM-III
calls for "one or more distinct periods with a predominantly
elevated, expansive, or irritable mood." If the respondent
said "Yes" to the initial mania question (MQPG41L=1) then
the respondent was considered euphoric (MQPEUFOR=2). If the
respondent said "Yes" (1) to MQPG54 then the respondent was
considered irritable (MQPEUFOR=1).
The DSM-III definition of Criterion B for manic episode
requires a duration of at least one week during which, for
most of the time, at least three of the seven symptoms have
persisted (four if the mood is only irritable) and have been
present to a significant degree. These seven symptoms are
approximated by the following NHANES III questions:
DSM-III Symptom NHANES III Questions
1. Hyperactivity/hypersexuality G42W or G44W
2. Pressure to keep talking G45W
3. Thoughts racing G46W
4. Inflated self-esteem e.g.,
special gifts or powers G47W
5. Decreased need for sleep G48W
6. Distractibility G49W
7. Excessive involvement in
activities that have a high
potential for painful
consequences which is not
recognized, e.g., buying sprees G43W
MQPMNG1W-MQPMNG7W give whether the symptom is present or not
for the seven corresponding groups above.
The variable MQPMANIA can take five values:
1 No diagnosis
2 Manic episode without severity
3 Manic episode with severity
88 Blank but applicable
Blank
MQPMANIA = 1. No mania episode was diagnosed if the
respondent answered sufficient questions so that Criteria A
and B could be determined and did not qualify for a
diagnosis of manic episode.
MQPMANIA = 2. Manic episode without severity was diagnosed
if Criteria A and B were met but without severity (all no's
for MQPG57-MQPG60).
MQPMANIA = 3. Manic episode with severity was diagnosed if
Criteria A and B were met as well as severity (at least one
"Yes" for MQPG57-MQPG60).
MQPMANIA = 88. The manic episode variable was coded a
"Blank but applicable" value if the respondent did not
answer sufficient questions so that Criteria A and B could
be determined. The respondent must answer the initial mania
question (MQPG41), or the irritability question (MQPG54),
and at least 6 of the lifetime symptom questions
(MQPG41L-MQPG49L) as well as the appropriate worse episode
symptom questions (MQPG42W-MQPG49W).
MQPMANIA = Blank. The manic episode variable was coded a
"Blank" if the sample person was not eligible to receive the
mania questions.
MQPMNGSW, MQPMNSX1-MQPMNSX2: Total manic symptom group counts
The two variables MQPMNGSW and MQPMNSX2 code the total
number of positive manic symptom groups in the worst episode
(sum of groups MQPMNGP1 to MQPMNGP7 with a "Yes" response)
and during lifetime (questions MQPG42L to MQPG49L are
grouped into DSM-III groups 1 to 7 and the number of
positive groups is counted), respectively. The latter also
adds the euphoria or irritability symptom (1 <= MQPEUFOR <=
2). These variables range from 0-7 and 0-8, respectively.
MQPMNGSW is used in determining the diagnosis of manic
episode and MQPMNSX2 is used in the total symptom count.
The variable MQPMNSX1 reports the total number of positive
symptoms in the worst episode (sum of MQPMNGP1 to MQPMNGP8)
plus euphoria or irritable mood (1 <= MQPEUFOR <= 2) with a
range of 0-8. (Note that this variable is a sum of positive
symptoms, not positive symptom groups).
MQPFDMN, MQPLDMN: Age of first and last manic symptoms
The two variables MQPFDMN and MQPLDMN report the age of the
respondent the first and last time, respectively, he/she
experienced manic symptoms if he/she ever met criteria for
any manic episode (2 <= MQPMANIA <= 3). MQPFDMN uses the
age in MQPG61 and MQPLDMN combines the age and time frame
information in MQPG62, MQPG63 and MQPG64.
MQPDEPSE: The diagnostic variable "MQPDEPSE"
The variable MQPDEPSE indicates the DSM-III diagnosis of
major depression, single episode, and is constructed using
MQPDEP and MQPMANIA. The diagnosis of major depression,
single episode is not made if the depression is the sole
result of severe or non-severe bereavement (MQPDEP= 4 or 5)
or if a manic episode is present (MQPMANIA= 2 or 3). There
must be only one episode of major depression.
The variable MQPDEPSE can take five values:
1 No diagnosis
2 Major depression, single episode without severity
3 Major depression, single episode with severity
88 Blank but applicable
Blank
MQPDEPSE = 1. No major depressive episode was diagnosed
(MQPDEP=1) although there could be severe or non-severe
bereavement (MQPDEP=4 or 5) or some form of mania was
diagnosed (MQPMANIA=2 or 3).
MQPDEPSE = 2. A single episode (MQPG27=1) of major
depression without severity was diagnosed (MQPDEP=2) and no
manic episodes were present (MQPMANIA=1). MQPDEPSE = 3. A
single episode (MQPG27=1) of major depression with severity
was diagnosed (MQPDEP=3) and no manic episodes were present
(MQPMANIA=1).
MQPDEPSE = 88. The major depression, single episode
variable was coded "Blank but applicable" if one of the
following is true:
1. MQPDEPSE=1 and MQPBIPOL= (Blank or 88) and
MQPDEP= (Blank or 88)
2. MQPDEPSE=1 and MQPBIPOL= (Blank or 88) and MQPDEP=3
3. MQPDEPSE=1 and MQPBIPOL=1 and MQPDEP= (Blank or 88)
4. MQPDEPSE=1 and MQPBIPOL=1 and MQPDEP=3 and
MQPG27= (Blank, 888, or 999)
MQPDEPSE = Blank. The major depression, single episode
variable was coded a "Blank" if the sample person was not
eligible to receive the depression/mania questions.
MQPFDDSE, MQPLDDSE: Age of first and last depressive symptoms
associated with major depression, single episode
The two variables MQPFDDSE and MQPLDDSE code the age of the
respondent the first and last time, respectively, he/she
experienced depressive symptoms if he/she ever met criteria
for a major depression, single episode which was not due
solely to bereavement (2 <= MQPDEPSE <= 3). MQPFDDSE uses
the age in MQPFDDP and MQPLDDSE uses the age in MQPLDDP.
MQPDEPRT: The diagnostic variable "MQPDEPRT"
The variable MQPDEPRT indicates the DSM-III diagnosis of
major depression, recurrent, and is constructed using MQPDEP
and MQPMANIA. The diagnosis of major depression, recurrent,
is not made if the depression is the sole result of severe
or non-severe bereavement (MQPDEP=4 or 5) or if a manic
episode is present (MQPMANIA= 2 or 3). There must be more
than one episode of major depression.
The variable MQPDEPRT can take five values:
1 No diagnosis
2 Major depression, recurrent without severity
3 Major depression, recurrent with severity
88 Blank but applicable
Blank
MQPDEPRT = 1. No major depressive episode was diagnosed
(MQPDEP=1) although there could be severe or non-severe
bereavement (MQPDEP=4 or 5) or some form of mania was
diagnosed (MQPMANIA=2 or 3).
MQPDEPRT = 2. Recurrent episodes (2 <= MQPG27 <= (whole
life) or don't know how many spells) of major depression
without severity were diagnosed (MQPDEP=2) and no manic
episodes were present (MQPMANIA=1).
MQPDEPRT = 3. Recurrent episodes (2 <= MQPG27 <= (whole
life) or don't know how many spells) of major depression
with severity were diagnosed (MQPDEP=3) and no manic
episodes were present (MQPMANIA=1).
MQPDEPRT = 88. The major depression, recurrent variable was
coded "Blank but applicable" if one of the following is
true:
1. MQPDEPRT=1 and MQPBIPOL= (Blank or 88) and
MQPDEP= (Blank or 88)
2. MQPDEPRT=1 and MQPBIPOL= (Blank or 88) and MQPDEP=3
3. MQPDEPRT=1 and MQPBIPOL=1 and MQPDEP= (Blank or 88)
4. MQPDEPRT=1 and MQPBIPOL=1 and MQPDEP=3 and
MQPG27= (Blank, 888, or 999)
MQPDEPRT = Blank. The major depression, recurrent variable
was coded a "Blank" if the sample person was not eligible to
receive the depression/mania questions.
MQPFDDRT, MQPLDDRT: Age of first and last depressive symptoms
associated with major depression, recurrent
The two variables MQPFDDRT and MQPLDDRT report the age of
the respondent the first and last time, respectively, he/she
experienced depressive symptoms if he/she ever met criteria
for major depression, recurrent, which was not due solely to
bereavement (2 <= MQPDEPRT <= 3). MQPFDDRT uses the age in
MQPFDDP and MQPLDDRT uses the age in MQPLDDP.
MQPDYSA, MQPDYSD, MQPDYSTH: The diagnostic variable "MQPDYSTH"
The variable MQPDYSTH indicates the diagnosis of dysthymic
disorder. The diagnosis of dysthymic disorder is based on
Criteria A through D of the DSM-III definition of dysthymic
disorder. Criteria E and F were not assessed. This
disorder differs from major depressive disorder in that
during the past two years, the individual has been bothered
most or all of the time by symptoms characteristic of the
depressive syndrome but that are not of sufficient severity
and duration to meet the criteria for a major depressive
episode.
Criteria A, B, and C of the DSM-III are encompassed in the
variable MQPDYSA. This requires two years or more of
predominately depressive mood or marked loss of interest or
pleasure in all, or almost all, usual activities and
pastimes (MQPG03=1 or 104 weeks <= MQPG26 <= whole life).
The DSM-III definition of Criterion D for dysthymic disorder
contains 13 symptoms, at least three (3 <= MQPDYSD <= 7) of
which must be present during the depressive periods in order
to qualify for a diagnosis. Seven of these symptoms are
covered by the following NHANES III questions.
DSM-III Symptom NHANES III Questions
1. Insomnia or hypersomnia G08L or G09L
2. Low energy, chronic tiredness G10L
3. Feeling inadequate/low self-
esteem G14L
5. Trouble thinking G15L or G16L
7. Less interest in pleasurable
activities G13L
10. Less active or talkative G11L or G12L
13. Recurrent thoughts of death
or suicide G17L or G18L or G19L
DSM-III symptoms not available in the NHANES III
4. Decreased effectiveness
6. Social withdrawal
8. Irritability
9. Lack of pleasure in rewards
11. Brooding about the past or self-pity
12. Crying spells
The variable MQPDYSTH can take five values:
1 No diagnosis
2 Dysthymic disorder with no major depressive
episode
3 Dysthymic disorder with major depressive episode
88 Blank but applicable
Blank
MQPDYSTH = 1. No dysthymic disorder was diagnosed if the
respondent answered sufficient questions so that Criteria A
through D could be determined and did not qualify for a diagnosis
of dysthymic disorder.
MQPDYSTH = 2. Dysthymic disorder was diagnosed if the
respondent met Criteria A through D but did not have a diagnosis
of major depressive episode (MQPDEP not equal to 3).
MQPDYSTH = 3. Dysthymic disorder was diagnosed if the respondent
met Criteria A through D and had a diagnosis of major depressive
episode as well (MQPDEP = 3).
MQPDYSTH = 88. The dysthymic disorder variable was coded a
"Blank but applicable" value if the respondent did not
answer sufficient questions so that Criteria A through D
could be determined. The respondent must answer the initial
two year depression question MQPG03 or the length of spell
question MQPG26 and at least nine of the 12 lifetime symptom
questions listed above for Criterion D plus MQPG03.
MQPDYSTH = Blank. The dysthymic disorder variable was coded
a "Blank" if the sample person was not eligible to receive
the depression questions.
MQPBIPOL: The diagnostic variable "MQPBIPOL"
The variable MQPBIPOL indicates the DSM-III diagnosis of
bipolar disorder, and is constructed using MQPDEP and
MQPMANIA. The diagnosis of bipolar disorder is made only if
there has ever been a manic episode.
The variable MQPBIPOL can take eight values:
MQPBIPOL = 1. No bipolar disorder was diagnosed if there
has never been a diagnosis of manic episode.
MQPBIPOL = 2. Bipolar disorder is diagnosed if severity and
exclusion criteria are met for both a manic and a major
depressive episode (MQPMANIA=3 and MQPDEP=3).
MQPBIPOL = 3. Bipolar disorder is diagnosed if severity and
exclusion criteria are met for a manic episode (MQPMANIA=3),
but a major depressive episode is either absent (MQPDEP=1,
4 or 5) or the diagnosis is missing (MQPDEP=Blank or 88).
MQPBIPOL = 4. Bipolar disorder is diagnosed if severity and
exclusion criteria are met for a manic episode (MQPMANIA=3), but
not for a major depressive episode (MQPDEP=2).
MQPBIPOL = 5. Bipolar disorder is diagnosed if no manic
episode met both severity and exclusion criteria
(MQPMANIA=2) and a major depressive episode is either absent
(MQPDEP=1, 4 or 5) or the diagnosis is missing (MQPDEP=Blank
or 88).
MQPBIPOL = 6. Bipolar disorder is diagnosed if no manic
episode met both severity and exclusion criteria
(MQPMANIA=2) and the major depressive episodes may or may
not meet both severity and exclusion criteria (MQPDEP=2 or
3).
MQPBIPOL = 88. The bipolar disorder variable was coded a
"Blank but applicable" value if the diagnosis for manic
episode is missing (MQPMANIA=Blank or 88).
MQPBIPOL = Blank. The bipolar disorder variable was coded a
"Blank" if the sample person was not eligible to receive the
depression/mania questions.
MQPFDBI, MQPLDBI: Age of first and last manic symptoms
associated with bipolar disorder
The two variables MQPFDBI and MQPLDBI report the age of the
respondent the first and last time, respectively, he/she
experienced manic symptoms if he/she ever met criteria for
any bipolar diagnosis (2 <= MQPBIPOL <= 6). MQPFDBI uses
age at first manic symptoms (MQPFDMN) when 2 <= MQPBIPOL <=
6 or age at first depressive symptoms (MQPFDDP) if
MQPBIPOL=2, 4 or 6 and 0 <= MQPFDDP <= MQPFDMN. MQPLDBI
uses age at last manic symptoms (MQPLDMN) when 2 <= MQPBIPOL
<= 6 or age at last depressive symptoms (MQPLDDP) if
MQPBIPOL=2, 4 or 6 and MQPLDDP >= 0 and MQPLDMN <= MGPLDDP
<= 54.
MQPBIPII: The diagnostic variable "MQPBIPII"
The variables MQPDEP and MQPMANIA report the DSM- III
syndromes of major depressive episode and manic episode,
respectively, and are used to construct various DSM-III
diagnoses. The variable MQPBIPII is the DSM-III diagnosis
of atypical bipolar disorder (bipolar disorder, type II).
The diagnosis of atypical bipolar disorder is made only if
the respondent:
1. Does not meet criteria for bipolar disorder
(MQPBIPOL=1)
2. Does not meet criteria for a manic episode (MQPMANIA=1)
3. Has a major depressive episode (MQPDEP=2 or 3)
4. Has euphoria or irritability (1 <= MQPEUFOR <= 2)
5. Has some symptoms of mania (1 <= MQPMNGSW <= 3)
The variable MQPBIPII can take five values:
1 No diagnosis
2 Atypical bipolar disorder without severity
3 Atypical bipolar disorder with severity
88 Blank but applicable
Blank
MQPBIPII = 1. No atypical bipolar disorder is diagnosed if
there has ever been a manic episode (2 <= MQPMANIA <= 3) or
bipolar disorder (2 <= MQPBIPOL <= 6) and a major depressive
episode is absent or missing (MQPDEP=1, 4, 5, 88, or Blank).
MQPBIPII = 2. Atypical bipolar disorder without severity is
diagnosed if a major depressive episode without severity is
present (MQPDEP=2) and the criteria for a manic episode is
not met (MQPMANIA=1) but euphoria or irritability is present
(1 <= MQPEUFOR <= 2) and some manic symptoms are present (1
<= MQPMNGSW <= 3).
MQPBIPII = 3. Atypical bipolar disorder with severity is
diagnosed if a major depressive episode with severity is
present (MQPDEP=3) and the criteria for a manic episode is
not met (MQPMANIA=1) but euphoria or irritability is present
(1 <= MQPEUFOR <= 2) and some manic symptoms are present (1
<= MQPMNGSW <= 3).
MQPBIPII = 88. The atypical bipolar disorder variable was
coded "Blank but applicable" if one of the following is
true:
MQPBIPII=1 and MQPDEP= (Blank or 88)
2. MQPBIPII=1 and MQPMANIA= (Blank or 88) and MQPDEP=3
MQPBIPII = Blank. The atypical bipolar disorder variable
was coded a "Blank" if the sample person was not eligible to
receive the depression/mania questions.
MQPFDBII, MQPLDBII: Age of first and last manic symptoms
associated with atypical bipolar disorder
The two variables MQPFDBII and MQPLDBII report the age of
the respondent the first and last time, respectively, he/she
experienced depressive symptoms if he/she ever met criteria
for any atypical bipolar disorder diagnosis (2 <= MQPBIPII<= 3).
MQPFDBII uses age at first depressive symptoms (MQPFDDP) and
MQPLDBII uses age at last depressive symptoms (MQPLDDP).
MEC ADULT QUESTIONNAIRE (Except DIS)
The MEC Adult Questionnaire was administered to all examinees aged 17
years and older in the mobile examination center (MEC). Conducted by
a trained interviewer in a private room to ensure confidentiality, the
automated questionnaire included sections on drug, alcohol, and
tobacco use, sexual experience, women's reproductive history, and
mental health. Because this questionnaire was administered in the
examination center, the MEC examination sample weight (WTPFEX6) should
be used for data analysis. For more information on the use of sample
weights in NHANES III data analysis, refer to the NHANES III Analytic
and Reporting Guidelines (U.S. DHHS, 1996b).
Several portions of the MEC Adult Questionnaire were asked of
examinees within specific age groups, and others were specific to one
gender. For example, the cognitive-function section was administered
to examinees 60 years and older, and the birth control-use section was
administered only to women. Age and sex check items that were part
of the questionnaire have been retained in the documentation and can
be used to determine these subsets. One portion of the questionnaire
(Section G), the Diagnostic Interview Schedule, was edited and
documented separately (see Diagnostic Interview Schedule).
A modified MEC Adult Questionnaire was administered to adults 20 years
and older during the interview portion of the Home Examination. It
included sections on tobacco use, cognitive function, selected medical
conditions, reproductive health, and medicine, vitamin, and mineral
usage. Questions from the two interviews can be combined for
analysis; however, the analyst should be aware of slight differences
between the questionnaires. For example, the reproductive health
section of the interview administered in the Home Examination was
shorter, and skip patterns were not identical to those in the MEC
Adult Questionnaire. For analyses of combined data from the MEC Adult
and the Home Examination interviews, MEC+home examination weights
(WTPFHX6) should be used (see Home Examination, Interview).
Data processing and editing were performed for the consistency of
responses within the sections of the questionnaire. Notes have been
provided both for standardized and recoded variables and for variables
requiring additional explanation. The notes reference the questions, by
section and number, from the questionnaires which can be found in the
Plan and Operation of the National Health and Nutrition Examination
Survey, 1988-1994 (NCHS, 1994; U.S. DHHS, 1996b).

NOTES
MAPB1: Age eligibility for cognitive function test
This test of affective memory (Albert, 1991), given to MEC
examinees 60 years and older, was also included as part of the
interview in the Home Examination.
MAPE3S: Number of days drank alcohol in past year
This variable was created from the two-part (quantity and unit)
question E3 using the conversion factors 52 weeks/year and 12
months/year.
MAPE5S: Number of days drank nine or more drinks of alcohol in
past year
This variable was created from the two-part (quantity and unit)
question E5 using the conversion factors 52 weeks/year and 12
months/year.
MAPE6S: Number of days drank five or more drinks of alcohol in
past year
This variable was created from the two-part (quantity and unit)
question E6 using the conversion factors 52 weeks/year and 12
months/year.
MAPF7R: Age at time of first live birth
Question F7 (age at time of first live birth) was only asked of
women who had more than one live birth. To prevent redundant
questions, women who had one live birth were only asked question
F8, "Age at the time of the last live birth." This variable,
MAPF7R, was created to include responses for women who had only
one live birth and women who had multiple births. For women who
had only one live birth, their responses to question F8 were coded
into MAPF7R. For women who had multiple births, their responses
to question F7 were coded into MAPF7R.
MAPF12R: Pregnancy status recode
This variable combines responses from self-reported pregnancy
status (F12) with the results of urine pregnancy test conducted
in the mobile examination center on women 20-49 years of age. If
either the self-report or the test result was positive, then
MAPF12R was coded yes. Otherwise, if either the self-report or
test result was negative, then MAPF12R was coded no. If the
self-report was don't know and the test result was either
inconclusive or blank but applicable, then MAPF12R was coded don't
know. If the self-report was blank but applicable and the test
result was inconclusive, then MAPF12R was also coded don't know.
Finally, if both responses were blank but applicable, then MAPF12R
was coded blank but applicable.
MAPF18S: Number of months received WIC benefits
This variable was created from the two-part question (quantity
and unit) F18 using the conversion factor 12 months/year.
MAPF23: Age at last period
There were no comments or related responses that could be used to
clarify the responses for reported ages of last period that
appeared to be extreme. Analysts should review responses when
using this variable.
MAPF32S: Months since stopped taking birth control pills
This variable was created from the two-part question (quantity and
unit) F32 using the conversion factor 12/months per year.
MAPF33S: Total number of months took birth control pills
This variable was derived from the two-part question (quantity
and unit) F33 using the conversion factors 12 months/year.
Analysts should note that the reported length of time on birth
control pills may have exceeded the length of time that these
products were available in the U.S.
MAPF34R: Birth control pill codes
This variable was created to include a listing of all birth
control pills that were specified in question F34. It includes
both birth control pills that had original codes from the chart
that respondents were shown as well as those not included on the
chart but specified by the respondent. See the Appendix at the end
of this section for code listing.
MAPF34CS: Number of months since NORPLANT was implanted
This variable was derived from the two-part question (quantity
and unit) F34C using the conversion factor 12 months/year.
Analysts should be aware that the reported length of time
NORPLANT was used may have exceeded the length of time that this
product was available in the U.S.
MAPF39S: Number of months since stopped taking estrogen pills
This variable was created from the two-part question (quantity
and unit) F39 using the conversion factor 12 months/year.
MAPF40: Total years on estrogen pills
Analysts should be aware that the reported length of time for
estrogen pill use may have exceeded the length of time that these
products were available in the U.S.
MAPF43S: Number of months since stopped using estrogen cream,
suppository, or injection
This variable was created from the two-part question (quantity
and unit) F43 using the conversion factor 12 months/year.
MAPF44: Total years used estrogen cream, suppository, or
injection
Reported length of time for use of these estrogen products may
have exceeded the length of time that they were available in the
U.S.
MAPF47S: Number of months since stopped using hormone patches
This variable was created from the two-part question (quantity
and unit) F47 using the conversion factor 12 months/year.
MAPF48: Total years used female hormone patches
Reported length of time for use of hormone patches may have
exceeded the length of time that these products were available in
the U.S.
MAPF50: Age at first sexual intercourse
The question did not ask about first consensual sexual experience.
Therefore, responses of first intercourse at very young ages were
retained after reviewing comments made during the interview (e.g.,
reports of rape or incest).
MAPF51: Number of sexual partners
The value "990" represents reports of more than 990 sexual partners
as well as responses such as "too many to count."
MAPF53: Sex of sexual partners
This question was about sexual experience; it was not designed to
determine sexual preference.
MAPF54R: Number of partners that were female
If the response to this question was that all partners were female,
then this variable was recoded as the number of female partners
reported in F51.
MAPF57: Ever had genital herpes
In Phase 1, this question was asked, "Have you ever had genital
herpes?" In Phase 2, the question was changed to, "Has a doctor
ever told you that you had genital herpes?"

BONE DENSITOMETRY
Bone density of the proximal femur was measured on men and
non-pregnant women aged 20 years and over by a trained examiner in the
mobile examination center (MEC). Using dual energy x-ray
absorptiometry (DXA), areal bone density (bone mass per unit of
area scanned) was measured in five areas of the proximal femur.
These were the femoral neck, trochanter, intertrochanter, Ward's
Triangle, and total region.
Before the exam, screening questions were asked to determine
medical safety exclusions. Those excluded from testing were
examinees: who were females below age 60 for whom pregnancy test
results were positive or uncertain or for whom there was a
possibility of pregnancy; for whom both hips had been fractured
or broken previously; or who had hip pins or artificial hips.
Because these tests were administered in the mobile examination
center, the MEC examination sample weight (WTPFEX6) should be used
for data analysis. For more information on the use of sample
weights in NHANES III data analysis, refer to the NHANES III
Analytic and Reporting Guidelines (U.S. DHHS, 1996b).
A rigorous quality control program was used throughout the survey
to ensure data quality. Quality control (QC) of each individual DXA
instrument was monitored by scanning anthropomorphic phantoms on a
frequent basis (daily for spine phantom, weekly for hip phantom).
Comparability of the three DXA instruments was assessed by circulating
an additional spine phantom between mobile examination centers; this
"circulating spine phantom" was scanned once per stand. Every
anthropomorphic phantom scan was reviewed individually at the Mayo
Clinic, and results were plotted to compare with previous QC scan
results. All respondent scans also were reviewed individually at the
Mayo Clinic before being added to the database. For a detailed
description of the QC program and the results for Phase 1 of NHANES III,
see the reference by Wahner (1994). QC results for Phase 2 were similar
to those for Phase 1. Additional details about the bone density
procedure may be found in the references by Looker (1995) and Hologic
(1987).
Data processing and editing were performed to ensure internal
data consistency. Notes have been provided for variables
requiring additional explanation.

THIS PAGE INTENTIONALLY LEFT BLANK
NOTES
BDPEXFLR: Exclusion flag
This flag variable indicates whether or not the examinee was
ineligible to receive the bone densitometry procedure because of
known or possible pregnancy or because both right and left hips had
been fractured, pinned, or replaced with artificial hip joints in
the past.
BDPSCAN: Scan technically acceptable after review at the Mayo
Clinic
See 1994 reference by Wahner for rejection criteria.
BDPSIDE: Hip side that was scanned
The left hip was chosen as the default side for the bone density
scan because it was easier to scan this side given the position of
the DXA scanner in the bone density room. If the left hip had been
pinned or fractured previously or was artificial, the right hip was
scanned.
BDPWTARE, BDPWTBMC, BDPWTBMD: Bone mineral area, content, and density
of Ward's Triangle region
Phases 1 and 2 data for Ward's Triangle are not directly comparable
due to a change in the DXA software used to process the data. In
Phase 1, the location of Ward's Triangle was variable. The
computer algorithm actually searched a specific portion of the
femur neck and intertrochanter (2.7 cm x 3.5 cm) for the lowest
point of bone mass and then centered a fixed area box (10.5 mm x
10.5 mm)around this point. In Phase 2, however, the location was
fixed. The Ward's Triangle position was fixed at a mid-cervical
location rather than being the point of lowest bone mineral
density. Thus, users should be careful in interpreting observed
differences in Ward's Triangle data between Phases 1 and 2. In
addition, combining Ward's Triangle data from Phases 1 and 2 may
not be appropriate.

BDPWTBMD: Bone mineral density of Ward's Triangle
See note for BDPWTARE.
HOME EXAMINATION, INTERVIEW
The Home Examination interview was administered at the homes of
examinees aged 2-11 months and those aged 20 years and older who
were unable to travel to the mobile examination center (MEC). The
interview included sections similar to those found in other MEC
questionnaires: infant food frequency, cognitive function, selected
conditions/medicine, vitamin and mineral usage, tobacco use, and
reproductive health. Data from examinations conducted in the home
(body measurements, physical function, spirometry, and venipuncture)
have been included with the corresponding examination and laboratory
data; therefore, they have not been included here. Items from the MEC
Adult Questionnaire and the Home Examination interview can be combined
for analysis; however, there may be slight differences in the questions
the way in which they are administered. For example, the reproductive
health section in the interview during the Home Examination was shorter,
and the skip patterns were not the same. For analysis of the Home
Examination interview data alone or for combined MEC and Home
Examination questionnaire data, the MEC+home Examination weights
(WTPFHX6) should be used. Separate sample weights were not created for
the Home Examination. For more information on the use of sample weights
in NHANES III data analysis, refer to the NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996b).
The interview during the Home Examination was brief in comparison to
those conducted in the MEC. Like the MEC questionnaires, certain
sections were asked only of specific age and gender groups. For
instance, reproductive health questions were asked only of females aged
20 years and older. Cognitive function questions were asked of
examinees age 60 years and older. Tobacco use was asked of examinees
aged 20-60 years. The infant food frequency was asked of a parent or
other adult in the household member for each child aged 2-11 months.
Data processing and editing were performed for the consistency of
responses within the sections of the questionnaire. Notes have been
provided for variables that were standardized or recoded or those that
require additional comments.

NOTES
HXPD1: Age eligibility for cognitive function test
This test of affective memory, given to examinees 60 years and
older, was also included as part of the MEC Adult Questionnaire.
HXPH7: Age at last period
There were no comments or related responses that could be
used to clarify the response for reported ages of last
periods that appeared to be extreme. Analysts should review
responses when using this variable.
HXPH16S: Number of days since stopped taking birth control pills
This variable was created from the two-part question (quantity
and unit) H16 using the conversion factors 7 days/week, 30.4
days/month, and 365 days/year.
HXPH17S: Total number of months took birth control pills
This variable was derived from the two-part question (quantity
and unit) H17 using the conversion factor 12 months/year.
Analysts should be aware that the reported length of time for the
use of birth control pills may have exceeded the length of time
that these products were available in the U.S.
HXPH21S: Number of months since stopped estrogen pills
This variable was created from the two-part question (quantity
and unit) H21 using the conversion factor 12 months/year.
HXPH22: Total years on estrogen pills
Reported length of time for use of estrogen pills may have
exceeded the length of time that these products were available in
the U.S.
GALLBLADDER ULTRASONOGRAPHY
Gallbladder examinations were conducted on all examinees aged 20 to 74
years by a certified ultrasound technician in the mobile examination
center (MEC). The protocol for this component did not detail any
medical, safety or other exclusions.
When analyzing these data, the MEC examination sample weight
should be used (WTPFEX6). For more information on the use of
sample weights in NHANES III data analysis, refer to the NHANES
III Analytic and Reporting Guidelines (U.S. DHHS, 1996b).
Gallbladder examinations were conducted to estimate the
prevalence of gallstone disease in the United States. Testing
was done on examinees in both supine and left decubitus positions.
The main element of the exam was real-time ultrasonography, a
non-invasive technique for detecting gallstones.
Although sample persons were asked to fast for at least six hours
before the examination, non-fasting persons were not excluded
from the examination. The rate of acceptable exams did not differ by
fasting status.
Details of the data collection procedures and data collection forms for
the Gallbladder Ultrasonography component are included in the
Gallbladder Ultrasonography Procedures Manual (U.S. DHHS, 1996b) and the
Plan and Operation of the Third National Health and Nutrition
Examination Survey, 1988-94 (U.S. DHHS, 1996b).
All certified ultrasound technicians received training in the
physics of ultrasound, calibration of equipment, and technique of
administering the abdominal ultrasound examination. This training was
conducted at the time of hire and at least annually thereafter by a
radiologist and a physicist who were experts in ultrasonography. All
examinations were recorded on videotapes and mailed to consulting
radiologists who specialized in abdominal ultrasonography. No written
comments or technician findings were disclosed to the radiologists to
ensure an independent review of cases except for the "rapid review"
cases (in which immediate evaluations were needed due to abnormal
findings potentially requiring medical attention).
A diagnosis of gallstones was made using the common criteria of
echoes within the gallbladder with shadowing on two views.
Diagnoses first were obtained by the ultrasound technician in the
MEC and later were confirmed by a radiologist. If a right upper
quadrant or epigastric scar was observed and the gallbladder was
not seen, it was concluded that a cholecystectomy had been
performed previously. Data for other abnormal pathologies
observed in the surrounding areas, such as the liver or the right
kidney, also were collected and recorded. Persons in wheelchairs
received the ultrasound examination while sitting.
The radiologists' diagnoses in GUPR1DX1 and GUPR1DX2 were compared with
the technicians' diagnoses in GUPTDX1R and GUPTDX2R. If they agreed
with each other, then these were used as the final diagnoses (GUPFDX1R
and GUPFDX2R). If the radiologist and the technician disagreed and the
radiologist was not confident of the finding because of the poor quality
of the video, then the technician's diagnosis was used as the final
diagnosis. Also if the radiologist's diagnosis was missing, then the
technician's diagnosis was used as the final diagnosis. However, if the
radiologist and the technician disagreed and the radiologist had
reasonable confidence in his/her findings, then the video taped scan was
given to a senior radiologist for adjudication, and that senior
radiologist's diagnosis was used as the final diagnosis. The level of
agreement between the technician's diagnosis and the radiologist's
diagnosis was measured by the Kappa statistic and was found to be
excellent (Fleiss, 1981).
Analysts should use both final primary and secondary diagnosis
variables in analyses. If gallstones were present (codes 3-5),
it was indicated in the final, primary diagnosis (GUPFDX1R).
Data processing and editing were performed to ensure internal
data consistency. Notes have been provided for variables
requiring additional explanation.
Supplemental information was collected during the household
interview. Section J of the Household Adult Questionnaire
included questions on self-reported history of abdominal pain,
previous diagnosis of gallstones, gallbladder surgery, and
medical treatment to dissolve or remove gallstones. A question
on newer methods to dissolve gallstones or remove the gallbladder
was added in Phase 2 of the survey. This information can be found in
the Household Adult Data File.

NOTES
GUPFDX1R, GUPFDX2R: Final primary and secondary diagnoses
The radiologist's diagnoses were compared with the
technician's diagnoses to determine agreement and to select
cases for adjudication. The final primary and secondary
diagnoses were a result of this adjudication. Most
examined persons had only a single diagnosis, and the code
for that diagnosis was placed in GUPFDX1R. For those
persons with two diagnoses, the lowest numbered code was
placed in GUPFDX1R, and the other code was placed in
GUPFDX2R. However, analysts should check both variables for
specific codes of interest.
GUPGBPSZ: Size of the largest polyp
GUPGBPSZ indicates the size of the largest polyp if a polyp
was found during the technician's examination or after the
radiologist's review (code 13 in either GUPFDX1R or
GUPFDX2R).
GUPLCSTR, GUPLCSZE: Flag for liver cyst and the size of the
largest cyst
During the examination, the technician scanned the area
surrounding the gallbladder for other abnormal pathologies.
Liver abnormality is identified in the variable GUPQ38R.
GUPLCSTR indicates the presence of one or more cysts in the
liver. GUPLCSZE indicates the size of the largest cyst.
GUPLHMGR, GUPCHSZE: Flag for cavernous hemangioma of liver and
size of the largest lesion
During the examination, the technician scanned the area
surrounding the gallbladder for other abnormal pathologies.
Liver abnormality is identified in the variable GUPQ38R.
The presence of one or more hemangiomas of the liver is
recorded in the variable GUPLHMGR. The size of the largest
lesion is recorded in the variable GUPCHSZE.
GUPQ18: Thickness of gallbladder wall
The gallbladder for a person in a non-fasting state may be
contracted and appear to have a thickened wall. In such cases, the
gallbladder wall thickness may be greater than 3 mm and, according
to the computerized recording of results, would have been recorded
as code 14, "Abnormal GB -- Diffuse W.T., With NO Calcification"
although the gallbladder appeared to be normal to technicians and
radiologists. For those persons in a non-fasting status with a
contracted gallbladder, the final adjudicated diagnosis was edited
and appropriately coded to indicate a normal gallbladder.
GUPQ24R: Measurement of largest echo -- clump (mm)
This variable provides measurement of the largest gallstone
(codes 3 and 4 in GUPFDX1R or GUPFDX2R).
GUPQ37R: Other non-gallbladder findings -- renal
This variable is a recode of the response to question Q37.
GUPQ38R: Other non-gallbladder findings -- hepatic or liver
This variable is a recode of the response to question Q38.
GUPQ8A1-GUPQ8A6: Flag for abdominal scar and its location
To identify the location of a scar in GUPQ8A1-GUPQ8A6, refer to the
upper body illustration (p. 394) of the Plan and Operation of the
Third National Health and Nutrition Examination Survey, 1988-94
(NCHS, 1994; U.S. DHHS, 1996b).
GUPR1CNF, GUPR1QLT: Radiologist's confidence in diagnoses and
assessment of quality of the videotape (first reading)
Three levels were used on the quality control form to record the
radiologist's confidence in the diagnoses and assessment of the
videotape quality. If for either variable, level 3 was marked,
diagnoses from the corresponding readings were not used in
computing the final, adjudicated primary and secondary diagnoses.
GUPR1DX1, GUPR1DX2: Radiologists' first reading
All videotaped scans were mailed to a radiologist for
evaluation, which was recorded on a quality control form.
After reviewing the scanned cases, the radiologist marked a
maximum of two diagnoses on the quality control form and
then evaluated the quality of the tapes, confidence in the
diagnosis, and sometimes provided an optional, written
comment explaining the diagnosis. Most examined persons had
only a single diagnosis, and their code was placed in
GUPR1DX1. For those persons with two diagnoses, the lowest
numbered code was placed in GUPR1DX1, and the other code was
placed in GUPPR1DX2. However, analysts should check both
variables for specific codes of interest.
GUPR1ID, GUPR2ID: Radiologists' identification numbers
These are identification numbers for the radiologists
reviewing the videotapes. A total of four radiologists
reviewed the videotapes under professional services
contracts. After the first reading, all cases with
significant disagreements between the technician's diagnosis
and the radiologist's diagnosis were reevaluated by the
senior radiologist (radiologist number 4).
GUPRCSTR, GUPRCSZE: Flag for renal cyst and the size of the
largest cyst
During the examination, the technician scanned the area
surrounding the gallbladder for other abnormal pathologies.
Right kidney abnormality is identified in the variable
GUPQ37R. The presence of one or more cysts in the kidney is
identified in the variable GUPRCSTR. GUPRCSZE indicates the
size of the largest cyst.
GUPTDX1R, GUPTDX2R: Technician's primary and secondary diagnoses
Most examined persons had only a single diagnosis, and the
code was placed in GUPTDX1R. For those persons with two
diagnoses, the lowest numbered code was placed in GUPTDX1R,
and the other code was placed in GUPTDX2R. However,
analysts should check both variables for specific codes of
interest.
CENTRAL NERVOUS SYSTEM FUNCTION EVALUATION
Computerized neurobehavioral testing was administered to a random
half-sample of examinees aged 20-59 years by a trained examiner in a
soundproof room in the mobile examination center (MEC). A screening
questionnaire was administered to assess factors that might have
affected test performance. There were no medical or safety exclusions
for this component.
Because this examination was administered on a selected subsample in
the examination center, the central nervous system (CNS) sample weight
(WTPFCNS6) should be used for data analysis. For more information on
the use of sample weights in NHANES III data analysis, refer to the
NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b).
Three computerized tests were used to evaluate central nervous system
function. They were: (1) a simple reaction time test (SRTT), a basic
measure of motor response speed to a visual stimulus; (2) a symbol-digit
substitution test (SDST), a test of coding ability; and (3) a
serial-digit learning test (SDLT), a short-term memory test. These
tests are components of the Neurobehavioral Evaluation System 2 (NES2)
developed by Baker and Letz (1985; Letz, 1990). NES2 is a system of
computerized tests designed to assess neurobehavioral function in
epidemiological studies of populations with occupational or
environmental exposure to chemicals.
The tests were administered on a Compaq 286 DeskPro(TM) personal
computer (12.5 MHz, 80286 CPU chip) configured with 640K RAM, one
1.2MB floppy disk drive, one parallel port, two serial ports, a
standard game joystick controller board, and an Ethernet interface
board. The system used the standard, detachable keyboard with a
custom-made wooden keyboard overlay that left only the top row of
digit keys exposed to prevent inadvertent contact with keys not needed
in the testing; it also used a standard, monochrome (green) Compaq
monitor. In September 1991, between the conclusion of Phase 1 and the
initiation of Phase 2 data collection, the monitors were replaced with
comparable, new amber monitors due to a deterioration in display
performance. A push-button, computer-game joystick (NES2 Joystick by
Neurobehavioral Systems, Inc., Winchester, MA) was used to record the
SRTT responses.
The tests were administered by health technicians, MEC interviewers, and
translators who were trained to perform the testing. Before
examinations began, special training sessions were held at NCHS or at
the offices of the contractor responsible for survey operations.
Training sessions also occurred at MEC sites during the survey, and
retraining was done approximately twice per year. The test was
conducted in English or Spanish, and examinees who could not speak
English or Spanish were not tested. English or Spanish language
instructions appeared on the computer screen for each test, and the
examiner also gave the instructions verbally.
Translators were trained to administer the testing independently or
with a health technician. The training was conducted in the MEC by a
Spanish-speaking health technician, Spanish-speaking NCHS staff
member, or Spanish-speaking MEC interviewer trained to administer the
CNS test. Training for translators included reviewing the manual with
the trainer, performing the tests as an examinee, and administering
the examination in Spanish.
Physical comfort may have affected examinees' test results. The air
conditioning in the soundproof room used for testing sometimes failed
to maintain an optimally comfortable room temperature. Because of
this, room temperature (CNPTEMP) was recorded for use as a covariate;
however, this practice did not begin until the second year of the
survey. The location of the thermometer within the room and the time
that temperature was recorded were not consistent throughout the
survey. For instance, some examiners entered the temperature at the
beginning of the testing session, and others recorded it at the end of
the session. This source of error is likely to be small.
Initially, some trials of the SRTT were performed with both the
non-preferred hand and the preferred hand. Early in the survey, the
procedure was changed to perform all trials only with the preferred
hand. As a result, analysts may want to exclude SRTT data from those
examinees who used both hands for the test. The affected data have a
value of "2 Non-preferred hand used on trials 31-50" for the variable
CNPNBPH (LOG: Number of trials with preferred hand).
During Phase 2 of the survey, reading glasses were available for
examinees who forgot to bring their own reading glasses to the MEC.
Examinees could select from four pairs of glasses of different
diopters or magnifying powers (+1.0 diopter, +1.5 diopters, +2.0
diopters, and +2.5 diopters).
Although all examiners were well-trained in standardized procedures
for these tests, performance on neurobehavioral tests may have been
subject to an examiner effect. This would have been particularly
likely when the examiner encouraged the examinee during the exam, as
was the case in NHANES III. Therefore, analysts should consider using
the examiner number (CNPTECH) as a covariate in analyses of data from
these tests.
For details of the examination protocol, see the Neurobehavioral
Testing Procedures Manual (U.S. DHHS, 1996b).
Data processing and editing were performed to ensure internal data
consistency. Notes have been provided for variables requiring
additional explanation.

NOTES
CNP1LAT1-CNP1LAT9, CNP2LAT1-CNP2LAT9, CNP3LAT1-CNP3LAT9,
CNP4LAT1-CNP4LAT9: Latencies for trials 1-4
A total of five trials were conducted in the Symbol Digit
Substitution Test (SDST), a practice trial (not included in these
data) and four actual trials (trials 1-4). The practice trial was
primarily for training the examinee in the test procedure. It did
not accept incorrect responses, and data from the practice trial
are not included in this file. If the examinee entered an
incorrect digit, a short beep sounded, and no digit was entered on
the screen; to proceed, a correct digit had to be entered. If the
examinee made more than four errors during the practice trial, the
trial was repeated. If the examinee made more than four errors on
the second attempt of the practice trial, the test was
discontinued, and the next test was initiated automatically.
Symbols and digits were paired differently on each trial. Although
incorrect responses were allowed on the four actual trials, more
than four errors resulted in a message emphasizing the need to
avoid errors.
These variables represent the latency to enter each of the nine
digits of each trial. Incorrect responses were reported as
negative values.
CNP1SCOR-CNP8SCOR: Serial Digit Learning Test (SDLT) score
Note that to allow comparison with NES2 results from other
settings the scoring convention for this variable differs from
that usually applied to the NHANES III data, where 0 indicates
none or never. Examinees received a score of 0 if all eight
digits were entered correctly, 1 if six or seven digits were
entered correctly, and 2 if fewer than six digits were entered
correctly.
CNP1TOTL, CNP2TOTL, CNP3TOTL, CNP4TOTL: Total latency, trials 1-4
CNP1TOTL represents the time elapsed on trial 1 from the time
the first item was answered to the time the ninth item was
answered. Therefore, it does not include the latency to respond to
the first symbol.
CNP2LAT1-CNP2LAT9: Latencies for trial 2
See note for CNP1LAT1-CNP1LAT9.
CNP2TOTL: Total latency, trial 2
See note for CNP1TOTL.
CNP3LAT1-CNP3LAT9: Latencies for trial 3

See note for CNP1LAT1-CNP1LAT9.
CNP4TOTL: Total latency, trial 4
See note for CNP1TOTL.
CNPCBEST: Mean of two lowest error-corrected latencies
This single summary measure for the SDST is the mean of the
error-corrected latencies (CNPCLAT1-CNPCLAT4) on the two best
(lowest latency) of the four trials. The units for this summary
measure are "sec/correct digit."
CNPCLAT1, CNPCLAT2, CNPCLAT3, CNPCLAT4: Error-corrected latency for
trials 1-4
The error-corrected latency was calculated for each of the four
actual trials. It is the mean number of seconds per correct
digit for each trial, excluding the first item in the trial.
If the number of correct responses for latencies 2 through 9 was
0, CNPCLAT1 was set to missing (blank). Otherwise,
CNPCLAT1=CNP1TOTL/CNPCORR1.
CNPCLAT2: Error-corrected latency for trial 2
See note for CNPCLAT1.
CNPCLAT3: Error-corrected latency for trial 3
See note for CNPCLAT1.
CNPCLAT4: Error-corrected latency for trial 4
See note for CNPCLAT1.
CNPMENRT: Mean reaction time
To calculate the mean reaction time, values from the first ten
trials (CNPRT01-CNPRT10) were excluded as well as values from other
trials that were greater than or equal to 750 msec or less than or
equal to 50 msec. This mean may not be valid if the number of trials
included in the average was less than 20.
CNPSDRT: Standard deviation of the reaction time
To calculate the standard deviation of the reaction time, values
from the first ten trials (CNPRT01-CNPRT10) were excluded as well
as values from other trials that were greater than or equal to 750
msec or less than or equal to 50 msec. This statistic may not be
valid if the number of trials included in the calculation was less
than 20.
FUNDUS PHOTOGRAPHY
A photograph of the ocular fundus of one eye was taken on examinees aged
40 years and over by a trained examiner in the mobile examination center
(MEC). The protocol for this component did not detail any medical,
safety or other exclusions. However, if the designated eye was
unavailable due to an extremely small pupil, severe corneal or lens
opacity, complete retinal detachment, or other reason, the other eye was
photographed. If both eyes were unavailable, no photograph was taken.
Because the component was administered in the examination center, MEC
examination weights (WTPFEX6) should be used for data analysis. For
more information on the use of sample weights in the analysis of
NHANES III data, refer to the NHANES III Analytic and Reporting
Guidelines (U.S. DHHS, 1996b).
Photographs of the ocular fundus were taken to determine the presence
of diabetic retinopathy, age-related maculopathy, and other retinal
diseases that are the leading causes of vision loss in the United
States. A non-stereoscopic, color, 45-degree photograph, centered
between the optic nerve and the macula, was taken of one randomly
selected eye. The camera used was a Canon CR4-45NM "non-mydriatic"
fundus camera, which incorporated the use of an infrared video camera
to allow photographs to be taken in a darkened examination room
without the use of dilating drops.
In a darkened room, the sphincter muscle of the iris normally relaxes,
allowing for dilation of the pupil, usually to 6-10 mm in diameter.
The technician observed the eye's natural dilation on a special video
monitor and took the color photograph with a single flash of white
light. If the examinee wore a contact lens, the photograph was taken
directly through the contact lens. The entire procedure usually took
less than six minutes. Detailed information on the examination
procedure is in the Fundus Photography chapter of the Health
Technician's Manual (U.S. DHHS, 1996b).
The exposed film was mailed to the University of Wisconsin-Madison,
Department of Ophthalmology, where it was processed by a local
laboratory into transparencies that were evaluated for photographic
quality.
The ocular fundus images on the final transparencies were reviewed by
photograph graders to assess the presence of diabetic retinopathy,
age-related maculopathy, and other retinal diseases. The grading
system used for classifying diabetic retinopathy was based on a
modification of the Airlie House Classification Scheme (Diabetic
Retinopathy Study Group, 1981; Klein, 1984; Klein, 1986; The Early
Treatment Diabetic Retinopathy Study Group, 1991).
The Modified Airlie House Classification of Diabetic Retinopathy slide
standards consist of 27 stereo pairs of color fundus photographs of
diabetic retinopathy and one slide depicting poor photographic quality.
The standard slides show diabetic proliferative disease and are used for
grading the severity of diabetic retinopathy. The set is available with
a detailed chapter outlining its use and a sample grading form.
Additional information is available from The Fundus Photograph Reading
Center, c/o Michael Neider, WARF Building Room 450, 610 Walnut Street,
Madison, WI 53705.
The fundus photography consultant provided extensive training to
technicians at their time of hire, and each technician's performance
was monitored in the field on a periodic basis.
Two sources of nonsampling or measurement error were monitored
throughout the survey, the picture taking procedure and the image
grading procedure. To ensure that adequate photographs were taken,
the technicians' performance was monitored by a review of photographs
at the University of Wisconsin and by review and retraining field
visits. To evaluate the grading procedure, 1500 transparencies were
chosen at random for use in assessing inter- and intra-grader
reliability. The Kappa statistic was chosen to assess agreement
(Fleiss, 1981). The measures of agreement were generally good to
excellent and improved across time.
Data processing and editing were performed to ensure internal data
consistency. Notes have been provided for variables requiring
additional explanation.

FPP1020: Fundus
When the fundus was absent (FPP1020=00), the grader was
instructed to stop. All ensuing fields, FPP1030 through FPP1270,
were then left blank by the grader. During data processing, the
blank fields were recoded "88 Blank but applicable."
FPP1060: Gradability status
Not all photographs were gradable. The principal reasons were
related to the camera (e.g., malfunction, poor focus, dirty lens)
and to the examinee (e.g., cataracts, eye movement, corneal
change, poor pupil dilation, lens implants). The grader was
instructed to stop when the entire field was ungradable
(FPP1060=06), at which point the remaining fields were left
blank. During data processing, the blank fields were recoded "88
Blank but applicable."
FPP1070: Diabetic retinopathy level
This variable represents the current state of severity of retinopathy
in the eye. As such, it differs from the summary diabetic retinopathy
score (FPPSURET) which represents the combination of current and past
retinopathy status.
FPP1230-FPP1266: Drusen details
Drusen vary in appearance, merging at one end of the spectrum
with the normal fundus background and at the other end with
diffuse degeneration of the retinal pigment epithelium. Typical
small drusen usually appear as individual, round, flat spots in
the plane of the retinal pigment epithelium. They may be pale
yellowish-white, contrasting sharply with the surrounding retinal
pigment epithelium, or only slightly more pale than the retinal
pigment epithelium and easily overlooked, even with careful
examination of well-focused photographs. Larger drusen typically
are yellow-white in color and often have visible thickness. Some
have sharp margins and a solid, nodular appearance, whereas
others have indistinct margins and a softer, more liquid
appearance. Drusen may be distributed as individual spots or may
appear to merge with adjacent drusen.
In NHANES III, two characteristics of drusen type (hard or soft)
and area were graded in a semi-quantitative fashion within and
outside the grid. Small punctate drusen (usually less than 95
microns in diameter) were classified as hard drusen; larger
drusen were classified as soft. No attempt was made to further
characterize soft drusen by appearance as soft distinct or
indistinct.
Drusen area was estimated within a central circle of the grid,
within the grid, and outside the grid. The area covered by
drusen was estimated by mentally moving together all hard or soft
drusen as if they were confluent and comparing this area with
those of standard circles. The estimate of drusen area was
classified into one of four categories: smaller than a circle
with a diameter of 95 microns (comparable to the 63-micron
diameter circle used in a 30-degree field), smaller than a circle
with a diameter of 375 microns (250-micron diameter in a
30-degree field), smaller than a circle with a diameter of 960
microns (640-micron diameter in a 30-degree field), or equal to
or larger than a circle with a diameter of 960 microns.
FPPPHOTO: Photographic status
Fundus photographs were not taken on all examinees who came to
the mobile examination center. The principal reasons were
refusal to cooperate, equipment failure, physical inability, and
insufficient time.
FPPSUDRU: Summary drusen score
The summary drusen score was derived from a combination of values
from several variables.
Definite drusen present: FPP1230, hard drusen, and/or FPP1240,
soft drusen, were coded "02 Yes."
Questionable drusen present: Definite drusen were not present,
and FPP1230, hard drusen, and/or FPP1240, soft drusen, were/was
coded "01 Questionable."
No drusen present: Neither definite nor questionable drusen was
present, and FPP1230, hard drusen, and/or FPP1240, soft drusen,
were/was coded "00 None."
Cannot grade drusen: FPP1230, hard drusen, and FPP1240, soft
drusen, were both coded "08 Can't grade."
Blank but applicable: FPP1060, gradability, was coded "06
Entire field ungradable," or FPP1020, fundus, was coded "00
Absent" or "88 Blank but applicable."
FPPSUMAC: Summary age-related maculopathy score
The summary age-related maculopathy score was derived from a
combination of values from several variables. A detailed
description of lesions as defined by the Wisconsin Age-Related
Maculopathy Grading System is available (Klein, 1991; NTIS,
1991).
Late age-related maculopathy: At least one of the following
variables was coded "02 Yes."
FPP1174, geographic atrophy
FPP1176, sub-retinal hemorrhage
FPP1178, sub-retinal fibrous scar
FPP1180, sensory serous (sub-retinal) detachment
Early age-related maculopathy: At least one of the following
three sets of conditions was met.
FPP1172, degeneration of retinal pigment epithelium (RPE),
was coded "02 Yes," and (FPP1230, hard drusen, and/or
FPP1240, soft drusen, were/was coded "02 Yes").
FPP1182, hyperpigmentation, was coded "02 Yes," and
(FPP1230, hard drusen, and/or FPP1240, soft drusen, were/was
coded "02 Yes").
FPP1240, soft drusen, was coded "02 Yes," and FPP1250, grid
area, was coded 02-04 (equal to or greater than a circle 95
microns in diameter).
No age-related maculopathy: Early and late age-related
maculopathy definitions were not met, and FPP1240, soft drusen,
was coded 00-02 (gradable).
"Cannot grade" age-related maculopathy: Early and late
age-related maculopathy definitions were not met, and FPP1240,
soft drusen, was coded "08 Can't grade."
Blank but applicable: FPP1060, gradability, was coded "06
Entire field ungradable," or FPP1020, fundus, was coded "00
Absent" or "88 Blank but applicable."
FPPSURET: Summary diabetic retinopathy score
The summary diabetic retinopathy score was derived from a
combination of values from several variables. That is, it
combines the diabetic retinopathy level variable (FPP1070) and
history of treatment for proliferative diabetic retinopathy
(using the photocoagulation treatment outside the arcades
variable (FPP1214) as a marker). A detailed description of
lesions as defined by The Early Treatment Diabetic Retinopathy
Study (ETDRS) is available in the ETDRS report #10 (The Early
Treatment Diabetic Retinopathy Study, 1991). The NHANES III
fundus photo grading protocol (NTIS, 1995) describes methods of
assigning diabetic levels.
Proliferative diabetic retinopathy: At least one of the
following two sets of conditions was met.
FPP1070, diabetic retinopathy level, was coded 060-070.
FPP1070, diabetic retinopathy level, has a code of anything
other than "012 Non-diabetic retinopathy," and FPP1214,
photocoagulation treatment outside arcades, was coded "02
Yes."
Moderate/severe non-proliferative retinopathy: FPP1070, diabetic
retinopathy level, was coded "041 Moderate non-proliferative" or
"051 Severe non-proliferative."
Mild non-proliferative retinopathy: FPP1070, diabetic
retinopathy level, was coded "020 Microaneurysms only" or "031
Early non-proliferative."
No diabetic retinopathy: FPP1070, diabetic retinopathy level,
was coded 010-015.
"Cannot grade" diabetic retinopathy: FPP1070, diabetic
retinopathy level, was coded "088 Can't grade."
Blank but applicable: FPP1060, gradability, was coded "06
Entire field ungradable," or FPP1020, fundus, was coded "00
Absent" or "88 Blank but applicable."
PHYSICAL FUNCTION EVALUATION
Physical function (PF) was evaluated on examinees aged 60 years and over
by a trained examiner using a battery of physical performance measures
in the mobile examination center (MEC) and at examinees'homes. The
protocol for this component did not detail any medical, safety or other
exclusions.
To determine which sample persons were home examinees, the DMPSTAT
variable (3=home-examined) should be used. When analyzing data for
combined home-examined and MEC-examined persons, the combined MEC- plus
home-examined sample weight should be used (WTPFHX6). When using only
MEC items or measures, the MEC examination sample weight should be used
(WTPFEX6). For more information on the use of sample weights in
NHANES III data analysis, refer to the NHANES III Analytic and
Reporting Guidelines (U.S. DHHS, 1996b).
Physical function was tested using certain movements that represent
musculoskeletal activities needed to carry out daily activities.
Gross shoulder joint movement, fine motor hand movement, lower
extremity motor functions, and integrated movement of balance and gait
were determined. Upper extremity functions were evaluated using Jette
and Branch (1984) right and left shoulder, external and internal
rotations (PFPRSER, PFPLSER, PFPRSIR, and PFPLSIR). The fine motor
function examination was a modification of a manual ability examination
in which a key was inserted into a lock and then was turned (PFPTKEY)
(Williams, 1982). The lower extremity motor, balance, and gait
evaluation items included time to get up from an armless chair five
times (PFPTSTND), a full tandem stand with the heel of one foot directly
in front of the toes of the other foot for a maximum time of 10 seconds
(PFPTTAND), and left and right knee flexing (PFPLFLEX and PFPRFLEX). An
eight-foot walk performed twice at the usual walking speed (PFPTWLKA,
PFPTWLKB, PFPNSTPA, and PFPNSTPB) was used also (Jette, 1985; Tinetti,
1986; Nevitt, 1989).
Items were scored by measuring the time required to perform the
maneuver (lock and key, chair rising, tandem stand, eight-foot walk),
by using scoring rules (shoulder rotation, knee flexing), and by
counting steps (eight-foot walk).
Examinees who were unable to perform a specific maneuver either because
they felt that it would have been unsafe or because they knew they were
unable to do it for reasons related to physical limitations or health
conditions were not required to make an attempt. For example, if an
examinee was in a wheelchair and was not able to stand up, he/she
skipped the following maneuvers: time to complete five chair stands
(PFPTSTND), right and left knee-hip flexion (PFPRFLEX and PFPLFLEX), and
tandem stand (PFPTTAND). The examinee was then asked, "Are you able to
walk alone without holding on to another person? You may use a cane or
walker." If he/she answered affirmatively, the examinee did the
measured walking (PFPTWLKA, PFPTWLKB, PFPNSTPA, and PFPNSTPB);
otherwise, he/she skipped the measured walking and ended the test. In
the data set, examinees unable to complete the maneuver for these
reasons were coded as "Blank," whereas examinees who did not perform the
test for reasons unrelated to physical limitations were coded as "8
Blank but applicable."
Persons aged 60 and over who refused or were unable to come to the
mobile examination center (MEC) were tested in their homes. Persons
found to be bedbound were excluded from the lower extremities part of
the PF evaluation (HXPBED). Aside from using an accessible, armless
chair in the examinees' homes (HXPCHIR), technicians used equipment and
procedures comparable to those used in the MEC.
Because technicians used equipment and procedures in examinees' homes
that were comparable to those used in the MEC, the home PF values were
incorporated into the MEC PF measures data set.
Refer to the Physical Function Examination Manual (U.S. DHHS, 1996b)
and the Home Examination Manual (U.S. DHHS, 1996b) for descriptions of
data collection procedures and methods.
At the time of hire, MEC and home examination health technicians were
trained to conduct the physical function evaluation. During annual site
visits, examination administration was observed, and re-training took
place. Applicable parts of the National Institute on Aging video
"Assessing Physical Performance in the Home-Part 1" were used to
demonstrate the PF procedures during initial training and re-training
(NIA, 1988).
Data processing and editing were performed to ensure internal data
consistency. Notes have been provided for variables requiring
additional explanation.

NOTES
PFPTKEY: Time to unlock lock (sec)
If the examinee was not able to open the lock within 60 seconds,
the maneuver was terminated, and his/her time was entered as 60
seconds.
PFPTSTND and PFPUSTND: Time to complete five stands (sec) and ability
to stand
A standardized wooden cube, 50-cm in height, was used as a prop
for the armless chair maneuvers in the MEC.
PFPTTAND: Time tandem stand held (sec)
The examiner stopped timing after 10 seconds even if the examinee
was able to maintain the tandem stand for a longer period of time,
and the examinee's time was entered as 10 seconds.
PFPUKEY: Ability to pick up key
The examinee had a maximum of 30 seconds to pick up the key. If
the examinee was not able to pick up the key within 30 seconds, the
maneuver was terminated, and the examinee proceeded to the next
item (PFPWC).
PFPUPWC: Can you get up from your chair/wheelchair by yourself?
This question was asked during the MEC and home exam; PFPWC was
recorded by the technician from observation in the MEC only.
PFPUSTND: Ability to stand
See note for PFPTSTND.
