Why do we measure physical inactivity?
Globally, about 25% of adults do not get adequate physical activity.(1) In the U.S., this number is closer to 50%.(2) Physical activity is an important component to preventing or reducing the severity of diseases like cardiovascular disease, type 2 diabetes, and breast and colon cancer.(1,2) Physical activity is also important for brain health. Physical activity improves cognition – the ability to think and learn – regulates emotions, and reduces anxiety and depression.(3) Researchers estimate over 100,000 deaths could be prevented a year by increasing physical activity by 10 minutes.(4)
How do we measure physical inactivity?
This metric includes adults 18 or older, who report no leisure-time physical activity in the past month.
Strengths of Metric
Limitations of Metric
Measuring physical inactivity can bring attention to groups who could benefit from improved neighborhood walkability, increased green space, community exercise programs, and other changes to their physical environment.(6)
The physical inactivity metric is restricted to adults 18 or older and does not provide information about children.
This metric only measures respondents who do not get any physical activity, but it does not identify individuals who get some, but not enough, physical activity.
The metric is self-reported and depends on the accurate reporting of the person surveyed.
Physical inactivity is calculated by the following formula:
Physical inactivity = [Respondents with no leisure time physical activity]Total respondents x 100%
This metric was calculated by aggregating estimates from smaller geographies to the congressional district level. For more information, please refer to the Congressional District Health Dashboard Technical Document.
Estimates for this metric are from one-year modeled PLACES Project Data (formerly 500 Cities Project)from the U.S. Centers for Disease Control and Prevention.
