Excludes adults who were pregnant and those who reported being unable to do physical activity. In addition, excludes 3206 adults (4.5%) with reported difficulty walking (without the use of equipment) because of a health problem.
Physical activity level is defined as active (≥150 minutes/week moderate-intensity equivalent activity), insufficiently active (some moderate-intensity equivalent activity but not enough to meet active definition), and inactive (no moderate-intensity equivalent activity that lasted at least 10 minutes).
Expenditures adjusted to 2012 dollars using the Personal Health Care Expenditure Price Index.
Covariates include sex, age group, race/ethnicity, census region, metropolitan statistical area, marital status, education, poverty level, health insurance status, smoking status, and MEPS year.
Estimates of mean difference and percent difference are based on models including inactive and insufficiently active as distinct categories therefore these estimates are not provided for the combined group. Percentages for the inactive and sufficiently active may not add to total due to rounding.
