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).

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.
