Individual, Social, and Neighborhood Associations With Sitting Time Among Veterans.

Background: Sedentary behavior is an increasingly recognized health risk factor, independent of physical activity. Although several correlates of sedentary behavior are known, little research has identified them among U.S. veterans, a population that faces disproportionate chronic disease burden. Methods: A survey was mailed to 1997 randomly selected veterans at a large urban Veterans Affairs medical center in 2012 and remailed in 2013 to nonresponders, resulting in a 40% response rate. We examined individual-, social-, and neighborhood-level factors in association with self-reported sitting time. Factors correlated with sitting time at P < .05 were included in a multiple linear regression model. Results: In the multivariate model, higher depression (B = 7.8), body mass index (B = 5.1), functional impairment (B = 4.2), and self-rated health (B = 68.5) were significantly associated with higher sitting time, and leisure time physical activity (B = -0.10) and being employed (B = -71.3) were significantly associated with lower sitting time. Conclusions: Individual-level, but not social- and neighborhood-level, variables were associated with sitting time in this population. This study identified individual-level targets for reducing sitting time and improving overall health among veterans. [ABSTRACT FROM AUTHOR]
