Component Description

The physical activity questionnaire (prefix PAQ) is based on the Global Physical Activity Questionnaire (GPAQ) and includes questions related to daily activities, leisure time activities, and sedentary activities. Additional information about the GPAQ can be obtained at the World Health Organization website.

Eligible Sample

All survey participants 2 or more years of age were eligible. Proxy respondents answered the questions for 2-11 year olds. The questions asked varied by age group. The target group in the codebook indicates which age groups were asked which questions.

Interview Setting and Mode of Administration

For respondents 2 to 11 and 16 or more years of age, the questions were asked before the physical examination, in the home, by trained interviewers using the Computer-Assisted Personal Interviewing (CAPI) system.

For respondents 12 to 15 years of age, these 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.

Data Processing and Editing

Limited editing was done on the data. 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

Since the PAQ questions for respondents 2 to 11 and 16 or more years of age were asked in the household interview, the interview sample weights should be used in their analysis. However, if the data is joined with data from the MEC, the MEC sample weights should be used. Analysis of the PAQ questions for 12 to 15 year olds should use the MEC sample weights as the questions were asked in the MEC.

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.

Next I am going to ask you about the time {you spend/SP spends} doing different types of physical activity in a typical week. Please answer these questions even if {you do not consider yourself/SP does not consider himself/herself} to be a physically active person.

Think of work as the things that {you have/SP has} to do such as paid or unpaid work, studying or training, household chores, and yard work. In answering the following questions, 'vigorous-intensity activities' are activities that require hard physical effort and cause large increases in breathing or heart rate, and 'moderate-intensity activities' are activities that require moderate physical effort and cause small increases in breathing or heart rate. Does {your/SP's} work involve vigorous-intensity activity that causes large increases in breathing or heart rate like carrying or lifting heavy loads, digging or construction work for at least 10 minutes continuously?
