Component Description

The Weight History section of the Mobile Examination Center (MEC) Interview (variable name prefix WHQMEC) provides personal interview data on topics related to body weight in adolescents 8-15 years of age. These topics include self-perception of weight, reasons for losing weight, and methods used to lose weight.

Eligible Sample

The target sample for the questions in this section is adolescents, age 8-15 years. Frequency counts were verified during the preparation of the file.

Interview Setting and Mode of Administration

The questions were asked at the mobile examination center, by trained interviewers, using the Computer-Assisted Personal Interviewing (CAPI) system as part of the Mobile Examination Center (MEC) interview. Proxy respondents were not permitted for this section. 

For details on the administration of the Weight History 8-15 years (WHQMEC_F) section, please refer to the NHANES 2009-10 MEC Interview Exam Manual and the Weight History (WHQMEC) Questionnaire on the NHANES website.

Quality Assurance & Quality Control

The CAPI system is programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire.

For details on the quality assurance/quality control process for this component, please refer to the NHANES 2009-10 Interviewer Procedure Manuals on the NHANES website.  

 

Data Processing and Editing

The WHQ511 responses 22 (I don’t want to be fat) and 23 (I want to be skinny) were collapsed into the new category WHQ510P 26 (I want to be skinny/I don’t want to be fat/because I’m overweight or obese).

WHQ510 30 (Other (specify)) responses such as “Because I’m fat” and “I think I’m overweight” also were recoded as WHQ510P 26. 

Frequency counts were verified during the preparation of the file. 

Analytic Notes

To provide 6 years of data for analysis, responses to WHQ510M (22) and WHQ510O (25) in the WHQMEC_D data file can be recoded as WHQ150P (26) in order to be comparable to the category WHQ510P (26) in the WHQMEC_E and WHQMEC_F data file.

Responses to WHQ030m, which asks if adolescents consider themselves now to be fat or overweight, too thin, or about the right weight, can be compared with proxy responses to WHQ030e in the Early Childhood (ECQ) questionnaire section.

Exam sample weights should be used for analyses.

Please refer to the  NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.
