There are four instruments that collect physical activity data by self reports.


The NIH-AARP Study Physical Activity Questionnaire (PAQ) asked participants to recall the time spent engaging in household, leisure time, transportation, and sedentary activities over the past 12 months.

You may view data dictionaries and formats for the PAQ-AARP files. Datasets can be obtained by submitting a request.
