Variable exercise: Physical activity level [C]

Literal Question

The variable was created from multiple survey questions, specifically T14., T15., T16., and T17.

Descriptive Text

Responses to multiple survey questions were first used to calculate the “Weekly Aerobic Activity Minutes” for each respondent. Responses for vigorous minutes of activity were multiplied by 2 to get a comparable level of physical activity minutes, which were then combined with responses for moderate minutes. The 2008 Health and Human Services Recommendations (http://www.cdc.gov/physicalactivity/everyone/guidelines/adults.html) were used for cut-offs. These indicate that 2.5 hours moderate or 1.25 hours vigorous physical activity per week are the minimum recommendations for health. Additionally they provide recommendations that for even greater health benefits people do 5 hours of moderate or 2.5 hours of vigorous physical activity per week. The four categories created here are: Not Active - No moderate or vigorous physical activity Somewhat Active- Some activity but less than recommended activity Active- Meets aerobic physical activity recommendations of at least 150 minutes (2.5 hours) of moderate physical activity or 75 minutes (1.75 hours) of vigorous physical activity per week but less than those recommendations for greater health benefits. Highly Active- Meets or exceeds greater health benefits of at least 300 minutes (5 hours) of moderate physical activity or 150 minutes (2.5 hours) of vigorous physical activity per week. The universe for this variable includes all adult respondents age 18 and older.
