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 22-4 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.
