Record Source: NHANES 2003 - 2004

Component Description

The Weight History section of the sample person questionnaire (variable name prefix WHQ) provides personal interview data on several topics related to body weight, including self-reported weight over the lifetime, self-perception of weight, attempted weight loss during the past 12 months, and methods used to try to lose weight and to keep from gaining weight.

Eligible Sample

The target sample for the questions in this section is persons age 16 years and older. However, target samples for some questions in this section vary. Please review the codebook carefully. Frequency counts were verified during the preparation of the file.

Interview Setting and Mode of Administration

Household interview; In-person.

The Interviewer Procedure Manuals and Exam Manuals and the survey questionnaires can be found on the NHANES website.

Quality Assurance & Quality Control

For details on the QA/QC process for this component, please refer to the Interviewer Procedure Manuals and Exam Manuals.

Data Processing and Editing

Self-reported height was standardized to inches using the conversion factors 0.3937 inches per centimeter and 12 inches per foot. Current and past self-reported weights were standardized to weight in pounds using the conversion factor 2.2046 pounds per kilogram.

Reported heights and weights considered to be physiologically implausible and the result of interviewer data entry error were coded as “missing.”

Responses to WHD150 (age when weighed the most) were top coded at 85 years for consistency with the top-coded age of the sample
person.

For WHD150, if maximum weight extended over more than one year, the interviewer recorded the most recent age at which the survey participant reported that weight.

Analytic Notes

Although these data were collected as part of the household questionnaire, if they are merged with the MEC exam data, exam sample weights should be used for the analyses.

Please refer to the Analytic Guidelines for further details on the use of sample weights and other analytic issues at: http://www.cdc.gov/nchs/nhanes/survey_methods.htm.
