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

    How often do you do LEISURE-TIME physical activities specifically designed to STRENGTHEN your muscles such as lifting weights or doing calisthenics? (Include all such activities even if you have mentioned them before.)

    [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

Methodology Notes: 

    Adults are classified as meeting the objective if they (1) participate in at least 150 minutes of light or moderate activity per week, 75 minutes of vigorous activity, or 150 minutes per week of an equivalent combination of activity and (2) report doing strengthening activities and respond that they did these activities 2 to 28 times per week.

    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) or strengthening activities 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.

    Estimates from the National Health Interview Survey (NHIS) and the Behavioral Risk Factor Surveillance System (BRFSS) are not comparable; the questions are different. Also, the NHIS is administered by personal interview, while the BRFSS is administered by telephone.

    Age Adjustment Notes: 

    This Indicator uses Age-Adjustment Groups:

    • Total: 18-24, 25-34, 35-44, 45-64, 65+
    • Sex: 18-24, 25-34, 35-44, 45-64, 65+
    • Race/Ethnicity: 18-24, 25-34, 35-44, 45-64, 65+
    • Educational Attainment: 25-34, 35-44, 45-64, 65+

    • Marital Status: 18-24, 25-34, 35-44, 45-64, 65+
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.
Trend Issues: 
Beginning with 2018, the American Community Survey questions are no longer available in the NHIS. As a result, tabulated data by disability are discontinued after 2017.
