DESCRIPTION OF SURVEY
Description of Survey: A detailed description of the design, content and
operation of HANES I is provided in the following reports: Plan and
Operation of the Health and Nutrition Examination Survey, DHEW Pub. No.
(HSM) 73-1310, Series 1, Nos. 10a and 10b, Public Health Service,
Washington, D. C., U. S. Government Printing Office, February 1973. Also
provided is a draft report on the augmentation survey of adults describing
the relevant field work conducted between July 1974 and October 1975.
TARGET POPULATION
Target Population: HANES I was conducted on a nationwide probability
sample of approximately 32,000 persons, ages 1-74 years, from the
civilian, noninstitutionalized population of the coterminous United
States, excepting those persons residing on Indian reservations. The
survey started in April 1971 and for many survey components was completed
in June 1974. The HANES I sample was selected so that certain population
groups thought to be at high risk of malnutrition (persons with low
incomes, preschool children, women of childbearing age and the elderly)
were oversampled at known rates. Adjusted sampling weights were then
computed within 60 age, sex and race categories in order to inflate the
sample in such a manner as to closely reflect the noninstitutionalized
population, ages 1-74 years, of the United States at the midpoint of the
survey.
Although the main emphasis of HANES I was on nutrition, a subset of those
sample persons aged 25-74 received a more detailed health examination
which was continued through October 1975. No particular oversampling of
subgroups of the population was done in this subsample (e.g., women of
childbearing age were not oversampled as they were for the major nutrition
component of HANES I). This subsample is also representative of the United
States population aged 25-74 during the time of HANES I.
After the nutrition survey was completed, the detailed examination given
to the 25-74 age group was continued until the total number of examined
persons was approximately double the number of examinees who received the
detailed examination during the nutrition survey.
DATA COLLECTION
Data Collection: Information for all examined sample persons in HANES I
was obtained by means of a household interview, a general medical history,
a 24-hour dietary intake recall interview, a food frequency interview, a
food program questionnaire, a general medical examination, dental,
dermatological and ophthalmological examinations, anthropometric
measurement, hand-wrist x-rays (of those ages 1-17 only) and 24
hematological, blood chemistry, and urological laboratory determinations.
In addition to the information received on all examined persons by means
of the above questionnaires, procedures and measurements, the following
data were gathered on the subsample of adults aged 25-74: a medical
history supplement; supplementary questionnaires concerning arthritis,
respiratory and cardiovascular conditions (when applicable); a health care
needs question- naire; a general well-being questionnaire; an extended
medical examination; x-rays of the chest and hip and knee joints;
audiometry, electrocardiography; goniometry; spirometry; pulmonary
diffusion and tuberculin tests; along with additional laboratory
determinations.
USE OF HANES DATA
With the goal of mutual benefit, NCHS requests the cooperation of
recipients of data tapes in certain actions related to their use:
A. Any published material derived from the data should acknowledge
the National Center for Health Statistics as the original source.
It should also include a disclaimer which credits any analyses,
interpretations, or conclusions reached to the author (recipient
of the tape) and not to NCHS, which is responsible only for the
initial data.
B. Consumers who wish to publish a technical description of the data
will make a reasonable effort to insure that the description is
not inconsistent with that published by NCHS. This does not
mean, however that NCHS will review such descriptions.
ERRORS IN THE DATA SETS AND SURVEY DIFFERENCES
The data users' tapes have been subjected to a great deal of careful
editing. However, due to the large volume of data in the series, it is
likely that a small number of errors or discrepancies remain undetected.
We would appre- ciate if any such errors are detected that they be brought
to our attention so that new corrected copies of the tape can be created
and errata sheets issued to previous purchasers.
Some of the continuous data items have extremely high or low values and we
have verified that they do in fact appear that way on the hard documents;
that is, we have verified that the values have not been incorrectly keyed.
In general, we have not attempted to resolve any differences that may
exist between estimates derived from the various subsamples of HANES I.
Nor have we made any comparisons between estimates from HANES I and
previous surveys conducted by the Division of Health Examination
Statistics.
VARIANCE ESTIMATION
Because the Health and Nutrition Examination Survey is based upon a
complex sample design, the assumptions of many statistical tests and
routinely avail- able statistical programs are not met. For this reason,
when estimates of the variances of statistics from HANES are computed, the
technique of estimation must be based upon complex sampling theory. In
order to provide the user with the capability of estimating the complex
sample variances, we have provided Strata and Primary Sampling Unit (PSU)
codes on the HANES user tapes in tape positions 194-198. However, these
codes are suitable for making variance estimates only for examination
locations 1-65 and 1-100. To compute variance estimates for examination
locations 1-35 or 66-100, it is necessary to recode the current Strata-PSU
codes according to the specifications that follow. The resultant recoded
Strata-PSU codes should be used only for locations 1-35 and 66-100.
One computer program that should be widely available sometime around the
summer of 1978 as part of the Statistical Analysis System (available from
the SAS Institute, Inc., Post Office Box 10066, Raleigh, North Carolina
27605) is capable of using the Strata-PSU codes provided for HANES to
compute complex sample variances. Other programs may also be available.
In those Strata, referred to as certainty or self-representing Strata, the
PSU codes are actually the segment numbers. Neither the Strata codes nor the
PSU codes are the original codes used in the formation of the HANES sample
design, but are nonetheless a unique Recoding of the original codes. For
further discussion of the sample design of HANES, the user should consult
the publications of the National Center for Health Statistics--Series-Nos.
10a and 14 and the detailed note for tape positions 158-193.
Recode Specifications for Strata-PSU Codes
First.--Create a files with only those records in the file for examination
locations 1-35.*
Second.--Retain 1he original Strata-PSU codes in Strata 7-10 and 13 in the
original form as the recoded Strata-PSU codes.
Third.--Recode the remaining strata according tot he chart below.
Fourth.--Repeat the process for examination locations 66-100.*

GENERAL NOTES, DEMOGRAPHIC DATA, HANES I
Demographic Information: An advance letter, announcing the forthcoming
arrival of an interviewer from the U. S. Bureau of the Census, was mailed
to each household that fell into the sample area. The interviewer
subsequently visited the household to ascertain its composition and to
administer a questionnaire, the primary purpose of which was to obtain
demographic information. The questionnaire was administered to each
potential sample person that was available and competent enough to respond
to questions. In the event that a potential sample person was not at home
at the time of interview, any responsible adult in the household was asked
to respond to the questions for the absent person.
Asterisks on the Tape Description: Some of the data items were obtained
only for a particular subsample of HANES. Consequently some of these items
appear to have a great deal of missing data (coded as blank) due to
nonresponse, but in fact the data are missing because the design of HANES
dictated that the item was to be obtained only for a particular subsample.
(For further discussion of the various subsamples in HANES the user should
see the detailed note for tape positions 158-193.)
To alert the user to this fact asterisks were put on the tape des-
cription. One asterisk denotes that the data item was obtained only on
examinees at locations 1-65, two asterisks denote that it was ob- tained
only at location 66-100 and three asterisks denote that it was obtained
only on examinees receiving the detailed examination.

DETAILED NOTES, DEMOGRAPHIC DATA
Tape Position 10 - Size of Place
Size of place classification was derived from the 1960 census. According
to the definition used in the 1960 census, the urban population was comprised
of all persons living in (a) places of 2,500 inhabitants or more incorporated
as cities, boroughs, villages and towns (except towns in New York, New
England, and Wisconsin); (b) the densely settled urban fringe, whether
incorporated or unincorporated, or urbanized areas; (c) towns in New England
and townships in New Jersey and Pennsylvania which contained no incorporated
municipalities as subdivisions and had either 2,500 inhabitants or more, or
a population of 2,500 to 25,000 and a density of 1,500 persons or more per
square mile; (d) counties in states other than the New England states, New
Jersey, and Pennsylvania, that had no incorporated municipalities within
their boundaries and had a density of 1,500 persons per square mile; and
(e) unincorporated places of 2,500 inhabitants or more not included in any
urban fringe. The remaining population was classified as rural.
Urban areas are further classified by population size for places within
urbanized areas and other places outside urbanized areas.
Tape Position 11 - SMSA
A standard metropolitan statistical area is basically a county or a group
of contiguous counties which contains at least one city of 50,000
inhabitants or more, or "twin cities" with a combined population of at
least 50,000. In addition to the county or counties containing such a
city or cities, contiguous counties are included in an SMSA if, according
to the 1960 Census, they are socially and economically integrated with the
central city. Each SMSA must include at least one central city, and the
complete title of an SMSA identifies the central city or cities.
Tape Positions 22 and 103 - Race
The race of the respondent was marked by observation and it was assumed
the race of all related persons was the same as the respondent unless
otherwise learned. The race categories were "White", "Negro", or "other."
If the appropriate category could not be marked by observation, then race
was asked. Persons of races other than White or Negro, such as Japanese,
Chinese, American Indian, Korean, Hindu, Eskimo, etc. were reported as
"Other." Mexicans were included with "White" unless definitely known to
be American Indian or of other nonwhite race.
Tape Positions 34-35 - Total Family Income Group
The income group represents the total combined family income for the past
twelve (12) months. It includes income from all sources such as wages,
salaries, social security or retirement benefits, help from relatives,
rent from property and so forth. The income groups were not reconciled to
the component parts (tape positions 36-94). The income component parts
were not asked when the gross income was greater than $6,999 per annum.
However, amounts greater than $6,999 appear in tape positions 37-40,
67-70, and 72-75. Some respondents reported a loss of income from their
nonfarm business, professional practice, partnership or farm and this
explains why some data fields are greater than $6,999, but the individual
total in tape positions 91-94 does not exceed this figure.
Tape Positions 95-99 - Family Unit Code
All related sample persons in the same family unit have the same computer
generated family unit code. This will enable detailed analysis of the
individual family unit.

Tape Positions 132-134 and 135-137 - Industry & Occupation Codes
A person's occupation may be defined as his principal job or business.
For this survey purpose, the principal job or business of a respondent is
defined in one of the following ways: If the person worked during the two
week interview period or had a job or business, the question concerning
his occupation (or work) applies to his job during that period. If the
respondent held more than one job, the question is directed to the one at
which he spent the most time. It refers to the one he considers most
important when equal time is spent at each job. A person who has not
begun work at a new job, is looking for work, or is on layoff from work is
questioned about his last full- time civilian job. A full-time job is
defined as one at which the person spen 35 or more hours per week and
which lasted two consecutive weeks or more. A person who has a job to
which he has not yet reported and has never had a previous job or business
is classified as a "new worker."
The 1970 census of population Alphabetical Index of Industries and
Occupations was used in the coding of both the industry and occupation.

Tape Position 146 - Land
Land used for farming purposes (Code 1 in Tape Position 146) was
identified as being rural land (Code 2 in Tape Position 13) consisting of
10 or more acres (Code 1 in Tape Position 14) with crop sales amounting to
$50 or more (Code 2 in Tape Position 15), or rural land (Code 2 in Tape
Position 13) consisting of less than 10 acres (Code 2 in Tape Position 14)
with crop sales amounting to $250 or more (Code 3 in Tape Position 16).
All Other land is classified as nonfarm (Code 2 in Tape Position 146).
Tape Positions 147-149 - Poverty Index
Poverty Index--Income status was determined by the Poverty Income Ratio
(PIR). Poverty statistics published in the Census Bureau reports1/ were
based on the poverty index developed by the Social Security Administration
in 1964. (For a detailed discussion of the SSA poverty standards, see
reference 2.) Modifications in the definition of poverty were adopted in
1969.3/ The standard data series in poverty for statistical use by all
executive departments and establishments has been established.4/
The two components of the PIR are the total income of the household
(numerator) and a multiple of the total income necessary to maintain a
family with given characteristics on a nutritionally adequate food plan3/
(denominator). The dollar value of the denominator of the PIR is
constructed from a food plan (economy plan) necessary to maintain minimum
recommended daily nutritional requirements. The economy plan is
designated by the Department of Agriculture for "emergency or temporary
use when funds are low."
For families of three or more persons, the poverty level was set at
three times the cost of the economy food plan. For smaller families and
persons living alone, the cost of the economy food plan was adjusted by
the relatively higher fixed expenses of these smaller households.
The denominator or poverty income cutoff adjusts the family poverty
income maintenance requirements by the family size, the sex of the family
head, the age of the family head in families with one or two members, and
the place of residence (farm, nonfarm). Annual revisions of the poverty
income cutoffs are based on the changes in the average cost of living as
reflected in the Consumer Price Index.
As shown in the table, the annual income considered to be the poverty
level increases as the family size increases. A family with any
combination of characteristics and with the same income as shown in the
table has been designated as having a PIR or poverty level of 1.0. The
same family with twic the income found in the table would have a PIR of
2.0. Ratios of less than 1.0 can be described as "below poverty," ratios
greater than or equal to 1.0, as "at or above poverty."
Poverty thresholds are computed on a national basis only. No attempt
has been made to adjust these thresholds for regional, State, or other
local variation in the cost of living (except for the farm, nonfarm
difference). None of the noncash public welfare benefits such as food
stamp bonuses or free food commodities are included in the income of the
low income families receiving these benefits.

Tape Positions 158-193 - HANES
HANES is a multistage, stratified, probability sample of loose clusters of
persons in land-based segments. In addition, HANES is composed of two
distinct examination components--a nutrition screening examination (taken
by all examinees) and a more detailed examination taken by a pre-selected
subsample of all examinees, ages 25-74. For the nutrition screening
examination, locations 1-35 and 1-65 constituted national probability
samples and for the detailed examination, locations 1-35, 1-65, 66-100 and
1-100 all constitute national probability samples. In other words, HANES
is composed of six distinct subsamples of the U.S. population. For a more
detailed discussion of the sample design see Series 1, No. 10a.
Since each of these six subsamples is a distinct subsample of the U.S.
population, such subsample requires a different set of weights. The
weights are based upon the probability of selection into the sample,
adjustments for nonresponse and further adjustments to approximate the
U.S. noninstitu- tionalized population as of the midpoint of each
subsample.
In order to select all of those examinees in a particular subsample, i.e.
received a particular exam component, it is necessary to exclude all
examinees with a weight of zero or blank. It is also necessary to exclude
all zero or blank weights because that is the only way to differentiate
missing data due to nonresponse from data that is missing because the
sample design dictated that a particular examinee was not supposed to
receive particular examination component.
It is suggested that any analyses that are desired by the researcher be
per- formed using the greatest number of examinees possible; that is, if
the researcher is interested in an exam component of the nutrition
screening examination he should use the weight and consequently the data
from the 65 location subsample rather than the 35 location subsample. For
the detailed examination, the researcher should use the 100 location
subsample rather than one of the others. However, some exam components
were only done in a particular subsample; for example, only at the first
35 locations. In that case, the researcher has no choice in selecting a
particular subsample.
There may be occasions when a researcher may want to make comparisons of
estimates obtained from various subsamples. For example, the prevalence
of some disease condition as estimated from the first 35 locations could
be compared with an estimate based upon locations 66-100. The researcher
may also want to formulate hypotheses using 1 subsample and test those
hypotheses using another subsample.

DETAILED NOTES, TB DATA
Tape Positions 205-237 - Lung Measurement Techniques
Surface areas of lungs - The technique used to measure lung surface areas
was that described by Harris et al in the American Journal of Medicine
50:756-763 1971.The technician first traced with a pencil on the
posterior-anterior (PA) and lateral films: 1) the left lung perimeter 2)
the right lung perimeter,excluding the heart and mediastinal shadows,and
3) the lateral lung perimeter, using the posterior margins of the
vertebrae,
the internal sternal margin and the line midway between the diaphragms.
The technician then again traced the lung perimeters using the magnifying
tracer of the planimeter. This data was interpreted by a Numonics model
1224 electronic digitizer, and areas were read and recorded from the
display console.
Thoracic diameters -- The PA diameter, given in centimeters, was the
maximum transverse diameter of the chest on the PA film, as measured by
the Numonics digitizer.The first and second lateral diameters were the
least distance in centimeters from the superior and inferior posterior
margins of the eighth thoracic vertebrae to the posterior margin of the
sternum, respectively. Measurements were made with the Numonics
digitizer.Thoracic diameters were not measured for examinees in the
Augmentation Survey.
Tracheal diameters - Tracheal diameters were measured at the levels of the
superior borders of the second (T2) and the third (T3) thoracic vertebrae.
Measurements were made with a straight edge and a square. Using a
straight edge, the tracheal borders at the levels of T2 and T3 were
marked. These lines were extended so as to best parallel their respective
tracheal walls.A perpendicular to the right tracheal border was
established with a square at the superior border of T2 and T3.
Measurement of the distance between tracheal walls was measured along this
perpendicular with a Fowler caliper,and readings were recorded to the
nearest hundredth of a centimeter. Tracheal diameters were not measured
for examinees in the Augmentation Survey.
Tape Positions 238-257 - Heart Size Measurement Techniques
Five measures of heart size were taken for each examinee in order to
assess cardiac pathology and heart enlargement, using techniques suggested
by Grover et al in Circulation, Volume XLVII, June 1973. As described in
the article, the technician used a straight edge and pencil to establish a
transverse line horizontally across the posterior-anterior (PA) x-ray
between the pair of ribs (left and right) which defined the maximum
intra-thoracic diameter. The distance between the internal margins of
these sites,B1 and B2,defined the maximum transverse diameter of the
thorax. A second line was drawn perpendicular to the first line, bisecting
the chest into left and right halves. The technician then identified the
points, one on the left and one on the right, which marked the most
lateral cardiac margins. Another perpendicular was drawn from each of
these points to the transverse thoracic line. The distance between point
A1 (where the perpendicular from the left cardiac border intersected the
transverse line) and the point A2 (where the perpendicular from the right
cardiac border intersected the transverse thoracic line) was measured and
recorded.This distance,A1 to A2,defined the maximum cardiac diameter on
the PA film.The technician then marked the point that identified the
junction of the right atrium and the superior vena cava, C1 and the point
that marked the cardiac apex, C2.The distance between these two points was
measured and recorded.The right cardio-phrenic angle,D1, was then
identified,as well as the junction of the atrial appendage with the main
pulmonary artery, D2.This distance, representing the cardiac broad
diameter, was measured and recorded. The technician then marked a
horizon- tal line on the lateral chest x-ray which transected the heart at
its widest diameter.The points where the line intersected the anterior and
posterior cardiac shadow were identified,and this distance was measured
and recorded as the greatest cardiac diameter on the lateral film, E1 to
E2.
Tape Positions 258-322, 323-387, 388-452-Cardiopulmonary Findings
In order to be able to determine the presence or absence of
cardiopulmonary findings, a recording form was developed by the principle
contract x-ray reader and the NHANES medical advisor. Since structural
abnormalities can directly or indirectly influence pulmonary mechanics,
the forms were expanded to include the presence of scoliosis, kyphosis,
pectus, and rib fractures. The forms were structured to permit:
1) grouping of abnormalities by location or system - e.g., chest wall,
pulmonary, lymphatic, pleural, and cardiovascular,
2) assessing the extent of the abnormalities (e.g., size and number of
nodules) and distribution (e.g., segmental and nonsegmental
infiltrates) of the disease,
3) suggesting etiologies (e.g., infections as the cause of nodules;
pneumonoconiosis as the cause of pulmonary infiltrates) when sufficient
information was available from the x-ray, and
4) recording into "open" recording space those observations and
abnormalities which did not otherwise fit into the coded form.
The assessment as to whether the nonsegmental nonhomogenous infiltrates
were minimal, moderate or advanced was made according to the Diagnostic
Standards and Classification of Tuberculosis (National Tuberculosis and
Respiratory Disease Association, New York, NY 1969). Objective criteria
concerning the other findings to be assessed were not available at the
time the form was designed.
The final report of the contractor responsible for making all heart size
and lung measurements and all assessments for cardiopulmonary pathology is
available to interested parties. In addition, a portion of that final
report has been excerpted and is included as Appendix I to this document.
In the excerpted portion,the contractor has provided assessments of the
validity and usefulness of each of the individual pathology findings
presented in this data set, as well as descriptions of problems
encountered in the reading and evaluation process.Users of this data set
are advised to review the excerpt prior to conducting any analyses of
these data.
Tape Positions 259, 324, and 389 - Kyphosis
Findings related to kyphosis were not formally recorded for subjects who
received the detailed examination during that part of NHANES I conducted
from 1971 to 1974.Consequently, no response is coded for those 3854
subjects. For some of those subjects an observation of kyphosis was
recorded in the "Comments" section of the coding form, but the
observations were not consistently recorded. In addition, a number of
subjects did not receive a lateral x-ray, and for these examinees the
assessment of kyphosis was not reliable.
Tape Positions 274-293, 339-358, 404-423 - Nodules
Review of the coding form used for the part of NHANES I conducted in
1971-74 prompted a revision of the section relating to nodules prior to
the Augmentation Survey conducted in 1974-75. In particular, the lung(s)
and specific lobe(s) of the lung(s) in which the largest and second
largest nodules were located are only coded for subjects examined in the
Augmentation Survey. The relative location(s) of the largest and second
largest nodules are only coded for subjects examined in 1971-74.The coding
schema are approximately equivalent, except that the schema used for the
subjects of the Augmentation Survey provides substantially more detail
than that used for the examinees receiving the detailed examination in
1971-74.
Tape Positions 294-304, 359-369, 424-434 - Infiltrates
Review of the coding form used for the part of NHANES I conducted in
1971-74 prompted a revision of the section relating to infiltrates prior
to the Augmentation Survey conducted in 1974-75.In particular,more
detailed coding schema were developed for the specific lobe in which
localized segmental infiltrates were located, and for the severity of
diffuse nonsegmental nonhomogenous infiltrates. In each case the less
specific schema can be derived by combining adjacent categories of the
more specific schema.
Tape Positions 388-452 - Pathology Final Readings
Reader opinion represents a useful assessment of radiographic
abnormalities. For example, Nicklaus et al (American Review of
Respiratory Disease 93: 889-899, 1966) have shown that reader opinion is
the best way to diagnose moderate to severe emphysema from the chest x-ray
and that it correlates well with histologic findings.Hence, the present
study utilized reader opinion to assess the presence or absence of heart
and lung pathology. Because such opinion has been shown to have
appreciable inter-observer and intra-observer error, two independent
readers were utilized to establish the presence or absence of pathology.
The pathology final readings do not represent a third reading of each
x-ray, but instead a synthesis of the first two readings. The x-rays of
those subjects examined in 1971-74 (the General Nutrition examination)
were only read once,so that for those examinees the final reading is
simply a copy of the first reading. The x-rays of those subjects examined
in the Augmentation Survey (conducted in 1971-74) were read twice by
independent readers.When the findings of the two readers agreed, the final
reading is a copy of those findings. When the readers disagreed in any
particular, the film was subjected to adjudication,in which the readers
jointly reviewed the film and came to agreement on the disputed item(s).In
a few cases,disputed films were referred to a third expert reader for
adjudication.
In this study, Dr. Lanie Eagleton, Associate Professor of Medicine and
Chief of the Pulmonary Division of the Southern Illinois University School
of Medicine, performed all the first readings.The "second" reader was one
of four radiology residents at the Southern Illinois School of
Medicine.Expert judgment on disputed films was provided by Dr. William
Sherrick, a staff radiologist at the Southern Illinois School of Medicine
specializing in chest radiology.
Tape Positions 501-532 - Pulmonary Diffusion
Measurements of single breath carbon monoxide diffusion capacity were per-
formed on all detailed examinees using a Collins modular lung analyzer.
This machine provides basic data from which estimates can be made of the
rate of diffusion of gases across the pulmonary membranes.
Each examinee who the physician did not disqualify performed first a
Forced Expiratory Spirogram to establish his forced vital capacity and
then three trials on the lung analyzer. Each trial consisted of: 1) a
maximal inspiration of a gas mixture containing air,10 percent helium
(He), and 0.3 percent carbon monoxide (CO), followed by 2) breathholding
for about 10 seconds, and finally 3) as complete and rapid an expiration
as the examinee could perform. The expired gas was analyzed for the
proportions of expired He and CO. Trials were separated by rest periods of
at least five minutes.
Each trial and the entire test was subjected to a variety of quality
control criteria, including:
1) Inspired volumes must be at least 80 percent of forced vital
capacity.
2) Inspiration times must be less than three seconds.
3) Breathholding times must be between 8.5 and 11.5 seconds.
4) Expired gas samples must be at least 500 ml.
5) The volumes of inspired gas must not decrease more than 200 ml during
breathholding.
6) The trials must be free of inhalation artifacts.
7) Expired CO and He measurements must not differ by more than 10 percent.
Calculations of pulmonary diffusion capacity (DLCO) were performed at the
end of the survey for all trials that were free of quality control
violations, using the following formula:
DLCO = (IVC * HEI / HEE - Weight in pounds - 75) * STPD factor *
(192 / Breathholding time) * (1 / (BP - 47))*
In ((COI / COE) * (HEI / HEE))
where:
IVC = Inspired vital capacity
HEI, HEE = Inspired and expired helium concentration
STPD = Standard Temperature and Pressure correction factor
BP = Uncorrected barometric pressure
COI, COE = Inspired and expired carbon monoxide concentration
A summary DLCO was also derived. The summary was the average of all
DLCO's that were within 10 percent of the largest, or the largest alone if
reproducibility had not been demonstrated or if only one trial was
available.
Tape Positions 551-563 - Tuberculin Test
Each adult ages 25-74 years selected in the sample for the more detailed
examination was given a tuberculin skin test as part of the examination
component relating to respiratory conditions.Due to the difficulty in
getting the examinees to return to the examining center 48-72 hours after
receiving their tuberculin tests for reading, tuberculin tests were only
to sample persons in stands 1-35. Examinees who had a history of a
positive reaction, tuberculosis, Isoniazid prophylaxis or who were
examined a day or two before the mobile examination unit was scheduled to
move were not given the tubercu- lin skin tests.
Simultaneous skin testing with PPD-S tuberculin antigen and PPD-B antigen
permitted differentiation between reactivity caused by infection with M.
tuberculosis and the other mycobacteria. Trained staff nurses
administered 5 tuberculin units contained in 0.1 cc solution into the left
arm and 5 units of PPD-B in 0.1 cc solution into the right arm.Both
antigens used in the survey examinations were obtained from the
Tuberculosis Program of the Centers for Disease Control, Public Health
Service.The tuberculin skin tests were read 48-72 hours after injection.
The indurated area was measured to the nearest millimeter at its widest
transverse diameter.
Further description of the tuberculin tests may be found in "Tuberculin
Skin Test Reaction Among Adults 25-74 Years1".

Quality Control
When the reading and evaluation of the x-rays in this data set was
initiated, objective criteria did not exist to assess the presence or
absence or degree of significance for many of the fields reported in the
section relating to cardiopulmonary pathology. After review of this data
set by staff members of the National Center for Health Statistics,and in
light of the comments raised by the primary contract reader, several
studies were initiated to validate selected items from the data set.Cobb's
angles were measured for all subjects with a positive findings for
scoliosis (see Carter, O.D., and Haynes, S.G.: Prevalence rates and risk
factors for scoliosis in U.S. adults: Results from the First National
Health and Nutrition Examination Survey (NHASES I). In Preparation). The
right descending pulmonary artery was measured for all subject with a
positive finding for pulmonary artery enlargement (as well as for a sample
of subjects who did not have positive findings) by an acknow- ledged
expert in that condition,and the results are currently being anlayzed to
determine proportion of false positives and negatives.Finally, all x-rays
reported to show some pleural disease have been re-read by an expert in
that condition, and these data are also currently being analyzed.
Users may wish to consider conducting validation studies of their own
prior to pursuing specific analyses.Under certain restricted
circumstances, it is possible to obtain from NCHS selected subsets of
x-rays from the original data set to conduct such studies.Contact Terence
Drizd or Dr.Suzanne Haynes of the Medical Statistics Branch, Division of
Health Examination Statistics, NCHS for more information.
APPENDIX I: EXCERPT FROM FINAL REPORT OF CONTRACT X-RAY READER
Kyphosis, a subjective evaluation, was a source of disagreement between
readers. The data should not be used as free standing prevalence data.
However,the adjudicated data should prove useful for comparison with and
for assessment of other pulmonary data, e.g., spirometry and physical
examina- tion data.
Scoliosis was a frequent finding. Most of the differences of opinion as
to the presence or absence of scoliosis occurred when there were small
angula- tions which had not been recorded by one of the readers.The data
should be further refined by having the angles of the scoliosis measured
so that the data become quantitative as well as qualitative.This data is
of good quality as a source of prevalence estimates as well as a source of
comparison with spirometric abnormalities.
Pectus excavatum, a subjective evaluation, was a source of substantial
disagreement between readers. Since this abnormality has been linked to
diaphragmatic abnormalities,it is an important finding to compare with the
other data, e.g., spirometry and physical examination findings.It should
not be used as a source of prevalence estimates for pectus excavatum.
Nodules were the most common abnormality. They were divided into those
the reader believed were:
1) nipple shadows,
2) extra-pulmonary densities,
3) radio-dense or calcified lesion judged to be secondary to a remote
granulatomous infection, such as a fungal infection, a viral
infec- tion, or tuberculosis, and
4) "other" nodules which had a reasonably high probability of
represen- ting a neoplasm, a tumor of non-infectious etiology,or
an infectious disease which had been recently acquired.
The nipple shadows and the extra-pulmonary nodules were recorded because
they were potential sources of error in identification of pulmonary
nodules. This recording was helpful in editing and adjudicating. It should
not be used for prevalence estimates and was not meant for correlation
with the other pulmonary data.
The sizes of the intrapulmonary nodules were recorded in millimeters. The
nodules were frequently asymmetrical. The measurement instructions were
not explicit as to how to measure an asymmetric nodule. Hence, the two
readings were frequently different by a few millimeters - usually no more
than two. However, this small difference in reading resulted in the
x-rays being re- called for adjudication.The difference was resolved by
reader #1 remeasuring the nodules and adjudicating the reading to the
maximal diameter of the nodule. This consumed a large amount of time.
However,the final data on the prevalence and the size of the nodule is
good data for publication. The enumeration of the nodules presented
problems,particularly when the densities near the hilum could be
interpreted as either a vessel or a nodule.When there was a difference of
opinion as to whether a nodule was present or absent,the lesions were
adjudicated as not present. The data on the number of nodules present
should prove useful for assessing the extent of the inflammatory process
in the lung.
The coding of the abnormalities by utilizing the smallest lung divisions
which were likely to encompass the lesion, (e.g., a segment of the lung)
presented a problem with adjudication. Precise anatomical location is
difficult to establish from x-rays even when both posterior-anterior and
lateral films are available. Furthermore, because of the variation in the
size of the nodules discussed above, the positions of the nodules were
frequently translocated because of differences in ranking of the size of
the nodules. This difference in segmental locations was arbitrarily
resolved by reader #1 after remeasuring the nodules and re-ranking them
according to their maximal diameter. However, the data on segmental
location is not sufficiently precise to permit publication as free
standing data. Yet, the data should prove useful in planning future
surveys, as well as in analyzing distribution of the abnormalities into
the regions of the lungs such as left versus right or upper versus lower.
The etiology of the nodules represents a judgement on the part of the
readers, and it proved to have reasonable inter-reader agreement. The
prevalence of post-inflammatory nodules was impressive. This data should
prove useful in assessing whether extensive inflammatory nodules of the
lung such as one sees in histoplasmosis have an appreciable effect on
pulmonary mechanics. For the nodules which were judged to non-infectious,
this data establishes an upper limit that one could expect in utilizing
x-rays and evaluating the prevalence of abnormalities such as carcinoma of
the lung.
There was very good agreement between the readers as to the presence of
pulmonary infiltrates.However, the readers varied as to how they coded a
given infiltrate. Platelike atelectasis presented a particular problem in
coding. This abnormality was coded by some as a nonhomogenous,
nonsegmental lesion;by others as a homogeneous symmetrical lesion;and by
others as "other" with a comment of platelike atelectasis. Because this
is a frequent abnormality in the lung,future coding forms should have an
independent space for coding platelike atelectasis.
Co-existence of a diffuse nonhomogeneous, nonsegmental pulmonary
infiltrate (which would be compatible with a previous tubercular or fungal
infection) and a more diffuse nonhomogeneous,nonsegmental infiltrate was a
frequent source of coding problems. Some readers coded this abnormality
as a nonhomogeneous and as a symmetrical infiltrate of the lung. Other
readers coded the infiltrates as both a nonhomogeneous nonsegmental and a
homogeneous segmental infiltrate, emphasizing that there were components
of both distributions present.It is my impression that these two lesions
frequently co-exist and are both related to a previous tubercular or
fungal infection -the major local infections causing the homogeneous and
symmetrical infiltrates and the long-standing spread of antigen diffusely
in the lung by bronchogenic spread leading to a more homogeneous and
symmetrical infiltrate which is probably a fibrosis in the lung. Future
recording forms should have an additional code which permits the reader to
record this observation without entering the homogeneous and symmetrical
infiltrate as an independent observation,or the coding directions should
be explicit as to how to make independent judgements as to whether there
were two components to the infiltrate in the lung.
The assessment as to whether the nonhomogeneous,nonsegmental infiltrates
were either minimal, moderate or far advanced, according to the former
NTRDA classification (Diagnostic Standards and Classification of
Tuberculosis, National Tuberculosis and Respiratory Disease Association,
New York,NY,1969) did not present unusual problems. This is a useful
assessment and should permit comparing the extent of the radiographic
lesion with the severity of the pulmonary function abnormalities and with
the presence or absence of pulmonary symptomatology.
In contrast,there was much inter-reader disagreement in assessing whether
the homogeneous, symmetrical infiltrates were extensive by making
judgement as to whether 1/3, 2/3 or the entire lung was involved.This data
should not be used for publication. However,it could be used for
comparison with assessments of the severity of the impairment by
spirometry and other pulmonary data. If these prove to correlate well,
then this assessment might be further refined for use in future surveys by
refining the coding instructions.
Assessing whether emphysema was present and whether the diaphragms were
flat was subjective.The coding instructions were not explicit on criteria
to use for judging the diaphragms as flat.The failure of all the readers,
except a single one of the second readers using a blank rather than a code
of 8 to signify the absence of findings,was the major source of recorded
differences. However, when this variability had been edited, and the
reading adjudicated, the result in assessment of the prevalence of these
findings represents a reasonable assessment for publication.This
prevalence of findings on x-rays underestimates the prevalence of
emphasyma. It has been previously reported (Am. Rev. Resp. Dis. 42:
889-899, 1966) that this is not useful in detecting milk to early stages
of emphysema. The data should be quite useful for use in conjunction with
other pulmonary data, including the findings on physical examination,
spirometry, carbon monoxide diffusion, and the size of the lungs as
assessed by planimetry. It represents confirmatory evidence for the
presence of emphysema. In future surveys, there should be criteria in the
instructions for assessing whether diaphragms are flat.
Calcified lymph nodes were prevalent. Instances where only one reader
thought a lesion was present were adjudicated as absence of this
finding.Lesions that were calcified and large were frequently recorded as
only calcified and not as enlarged.Enlarged nodes which were calcified
were adjudicated to be recorded only as "calcified nodes."
Difficulties in coding pleural disease were presented by thickening of the
pleura of the apex of the heart and of the lung. These were findings
which some readers did not code because they were frequent and considered
normal. In the adjudication procedure, if these pleural abnormalities
were marked and thought to represent an extension of significant pulmonary
disease, they were coded as abnormalities.In respect to the pleural
findings, these x-rays have been reexamined as a subset to review for
pneumonosis. This data should be useful in judging the extent and
etiology of the pleural disease and repre- sents an independent judgement
by a panel of experts on pleural disease.
Those x-rays that had a cardiovascular abnormality checked - azygous vein,
right atrial and right ventricular enlargement, cephalization,
interstitial fluids, Kerley lines, rosettes, alveolar fluid, and left
atrial and left ventricular enlargement, should be reevaluated by a panel
of cardiac experts to assess the nature of the cardiac abnormality.I
believe the data that has been collected is a useful screen for the
presence or absence of abnormality of the cardiovascular system but should
not be used to report prevalence of either left or right ventricular
disease.
The pulmonary artery enlargement assessment was made by subjective
evaluation. When both readers on the initial evaluation concurred as to
the presence of the pulmonary artery abnormality,that should be used as a
lower limit of the abnormality in the population. A more explicit criteria
for judgment of pulmonary artery enlargement should be developed and all
x-rays positive for this finding should be answered by these criteria.The
current data should be useful to compare with other pulmonary
observations,but should not be used as free standing data for estimating
the prevalence of pulmonary hypertension. Those x-rays that were coded as
showing pulmonary artery enlargement could be utilized as subsample for
further evaluation by a panel of experts in pulmonary vasculature disease.
