Component Description

The adult section of the Physical Activity questionnaire (variable name prefix PAQ) consists of questions PAQ605 through PAQ680. Based on the Global Physical Activity Questionnaire (GPAQ), it provides respondent-level interview data on physical activities.

Eligible Sample

Participants aged 18 years and over were eligible for the adult section of PAQ.

Interview Setting and Mode of Administration

PAQ was asked in the home, by trained interviewers, using the Computer Assisted Personal Interview (CAPI) system.

A proxy provided information for survey participants who could not answer the questions themselves.

Data Processing and Editing

The data were reviewed for completeness, consistency, and illogical values. Respondents who reported an average of 24 hours or more per day of activity had their time variables (PAD615, PAD630, PAD645, PAD660, PAD675, PAD680) set to missing. Users should carefully inspect the data for other values they may consider too high.

Analytic Notes

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

Suggested metabolic equivalent (MET) scores for the activities listed in this file are included in Appendix 1.

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.
