Does use of health behaviours to cope with stress predict sleep impairment in trauma-exposed community adults?

Individuals who have been exposed to trauma experience high levels of sleep impairment. Given the well-established negative effects of stress on sleep, the ways in which trauma-exposed individuals cope with stress is likely to be associated with their sleep. This study examined how the use of health behaviours (i.e., exercise, comfort eating, and maintaining a self-care routine) to cope relate to sleep impairment in a community sample of trauma-exposed adults (N = 84, mean age = 35.1, 83% female). We also tested whether use of health behaviours to cope moderates the relationship between psychological distress and sleep impairment. Results demonstrate that exercise and maintaining a self-care routine to cope are associated with less sleep impairment, while comfort eating to cope is associated with greater sleep impairment. Further, comfort eating to cope moderated the relationship between distress and sleep impairment. Findings suggest that the use of health behaviours to cope is differentially associated with sleep impairment, which has important clinical and research implications for the health of trauma-exposed adults.
