Weight History (WHQ_F)

Data File: WHQ_F.xpt

First Published: October 2012

Last Revised: NA

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-perception of weight, self-reported weight over the participant’s lifetime, 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

Trained interviewers asked these questions in the home using the Computer-Assisted Personal Interviewing (CAPI) system.

For details on the administration of the Weight History (WHQ_F) section, please refer to the Weight History Sample Person Questionnaire on the NHANES.

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.

Data Processing and Editing

Edits were made to some variables to ensure the completeness, consistency, and analytic usefulness of the data. Edits were also made, when necessary, to address data disclosure concerns. When a variable was modified globally, as part of the editing process, the third letter in the variable name was changed from a Q (i.e. WHQ) to a D (i.e. WHD). For example, height data were collected as feet and inches, but 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 or the result of interviewer data entry error, were coded as "missing".

If maximum weight (WHQ150) extended over more than one year, the interviewer recorded the most recent age at which the survey participant reported that weight.

All responses to WHQ150 (age when weighed the most) of 80 years and older were coded as '80' to be consistent with the way age of the survey participant was coded in the demographic file.

Analytic Notes

Four new response categories were added to WHD080 (How did you try to lose weight?) and WHD100 (What did you do to keep from gaining weight?). These categories were: "Ate more fruits, vegetables, salads", "Ate less sugar, candy, sweets", "Changed eating habits", and "Ate less junk food or fast food".

Although data in this file were collected as part of the household questionnaire, if they are merged with the MEC exam data, 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.
