Physical Activity among Veterans and Nonveterans with Diabetes

Table 3

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.

Variable	Category	Moderate PA	Vigorous PA	Total^† PA
		minutes (β) (95% CI)	minutes (β) (95% CI)	minutes (β) (95% CI)
Veteran status	Veteran	2.2 (0.6, 3.8)	−0.02 (−1.3, 1.3)	2.2 (−0.1, 4.5)
	Nonveteran	Reference	Reference	Reference
Diagnosed diabetes status	Diabetes	−8.0 (−9.4, −6.5)	−7.2 (−8.3, −6.1)	−15.2 (−17.3, −13.1)
	Pre-diabetes	−1.3 (−6.3, 3.7)	−1.5 (−4.4, 1.3)	−2.8 (−9.8, 4.2)
	Neither diabetes nor pre-diabetes	Reference	Reference	Reference
Age	One-year increase	−0.1 (−0.2, −0.1)	−0.3 (−0.4, −0.3)	−0.5 (−0.5, −0.4)

∗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.
