Methodology Notes

The Numerator question addresses aerobic physical activity only. A question to assess muscle-strengthening activity is not currently on the YRBSS questionnaire, but is expected to be added in the future.

Changes Between HP2010 and HP2020
This objective differs from Healthy People 2010 objective 22-6 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.
