Age-adjusted percentages are based on the 2000 U.S. Census Bureau standard population, using age groups 18–34, 35–49, 50–64, and ≥65 years, with 95% CIs indicated by error bars.

Per U.S. Department of Health and Human Services 2018 Physical Activity Guidelines for Americans, 2nd edition (https://health.gov/paguidelines). The aerobic physical activity guideline was met if the respondent reported engaging in ≥150 minutes per week of moderate-intensity aerobic physical activity or ≥75 minutes per week of vigorous-intensity aerobic physical activity, or an equivalent combination. The muscle-strengthening guideline was met if the respondent reported performing muscle-strengthening activities on ≥2 days per week.
