Religion, Combat Casualty Exposure, and Sleep Disturbance in the US Military.

Does religious involvement (i.e., attendance and salience) mitigate the association between combat casualty exposure and sleep disturbance among US military veterans? To address this question, we analyze cross-sectional survey data from the public-use version of the 2011 Health Related Behaviors Survey of Active Military Personnel. Results from multivariate regression models indicate: (1) Combat casualty exposure was positively associated with sleep disturbance; (2) religious salience both offset and moderated (i.e., buffered) the above association; and (3) religious attendance offset but did not moderate the above association. We discuss study implications and limitations, as well as some avenues for future research.
