Source: Centers for Disease Control and Prevention, National Center for Health Statistics, National Health Interview Survey (NHIS). Estimates are age-adjusted to the 2000 US standard population using 5 age groups: 18-24 years, 25-34 years, 35-44 years, 45-64 years, and 65 years and older. Annual sample sizes ranged from 9188 (2008) to 16 032 (2014) for men and from 11 955 (2008) to 19 904 (2014) for women. NHIS questions ask about frequency and duration of light-intensity to moderate-intensity and vigorous-intensity leisure-time physical activities, as well as the frequency of muscle-strengthening activities. Meeting the aerobic component of the 2008 Physical Activity Guidelines for Americans for this population is defined as reporting at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination. Meeting the muscle-strengthening component is defined as reporting muscle-strengthening activities at least 2 days per week. Error bars indicate 95% CIs.
