Questions Used to Obtain the National Baseline Data

From the 2008 National Health Interview Survey:

[NUMERATOR:]

The next questions are about physical activities (exercise, sports, physically active hobbies...) that you may do in your LEISURE time.

How often do you do VIGOROUS LEISURE-TIME physical activities for AT LEAST 10 MINUTES that cause HEAVY sweating or LARGE increases in breathing or heart rate?

[Read if necessary:] How many times per day, per week, per month, or per year do you do these activities?

  1. Never
  2. Unable to do this type activity
  3. _____ times per day/week/month/year
  4. Refused
  5. Don't know

About how long do you do these vigorous leisure-time physical activities each time?

_____ minutes/hours

How often do you do LIGHT OR MODERATE LEISURE-TIME physical activities for AT LEAST 10 MINUTES that cause ONLY LIGHT sweating or a SLIGHT to MODERATE increase in breathing or heart rate?

[If necessary, prompt with:] How many times per day, per week, per month, or per year do you do these activities?

  1. Never
  2. Unable to do this type activity
  3. _____ times per day/week/month/year
  4. Refused
  5. Don't know

About how long do you do these light or moderate leisure-time physical activities each time?

_____ minutes/hours

Methodology Notes

Adults are classified as meeting the objective if they participate in at least 150 minutes of light or moderate leisure-time activity per week, 75 minutes of vigorous activity, or 150 minutes per week of an equivalent combination of activity. Total minutes per week of light or moderate-intensity activity are calculated by multiplying the times per week adults report participating in light or moderate-intensity activity by the number of minutes reported. Total minutes per week of vigorous-intensity activity are calculated by multiplying the times per week adults report participating in vigorous-intensity activity by the number of minutes reported. To calculate minutes per week for the equivalent combination of moderate and vigorous-intensity activity, minutes per week of light or moderate-intensity activity are added to two times the minutes per week of vigorous-intensity activity.

If responses meet the criteria for one activity (vigorous or moderate) but the status of the other activity is unknown, the record is included in the numerator and the denominator. If responses do not meet the criteria for one activity and the status of the other activity is unknown, the record is dropped from the analysis.

Caveats and Limitations
Since the Numerator questions focus on leisure-time physical activities only, these data may not include physical activity by people whose jobs require regular or vigorous physical activity.
Changes Between HP2010 and HP2020
This objective differs from Healthy People 2010 objective 22-2 in that the objective has been modified to reflect the 2008 Federal Physical Activity Guidelines for Americans. The data for the Healthy People 2010 and 2020 objectives are not comparable.
