Adjusted∗ estimated differences in mean minutes of moderate, vigorous, and total physical activity (PA) per week among veterans and nonveterans in the United States, 2009 Behavioral Risk Factor Surveillance System.

*Adjusted for sex, race/ethnicity, education, household income, body mass index, and last health check-up.
†Total physical activity is the sum of moderate and vigorous physical activity.
β: linear regression coefficient, indicating the minutes per week associated with a one-unit change in the exposure variable.
CI: confidence interval.
