0285 Sleep health in veteran population with and without mild traumatic brain injury

Abstract Introduction Sleep duration is frequently observed in military and Veteran populations. Some of this effect may result from exposure to traumatic brain injury (TBI) during service. However, other features combat deployment, circadian disruption, chronic stress contribute poor sleep independent the effects TBI. In study we tested whether deployment with or without TBI was associated compared civilian controls. Methods a prospective Operation Enduring Freedom/Iraqi Freedom/ New Dawn Veterans repeated blast mild (mTBI) conducted at VA Puget Sound Healthcare System, self-reported quality assessed Pittsburgh Quality Index (PSQI). Age-matched civilians (CONciv) non-TBI deployed (CONdep) were included for comparison. The outcomes interest PSQI sum score its key components scored as 0-3. One way ANOVA paired comparison Bonferroni adjustment each component performed . Results A total 104 mTBI, 36 CONdep 15 CONciv participants included. Poor overall (PSQI sum>5) most reported by mTBI participants, followed (80 % vs. 50 11, p< 0.0001). Across virtually every feature, impairment pronounced CONdep: (mTBI VS. CONvic= 11.6 6.5 3, 0.0001), (5.5 hrs 6.6 7.1, onset insomnia (2.1 1.3 0.3, 0.0001) , maintenance (2.5 1.4 0.7, daytime sleepiness (1.3 0.6 0.4, function (1.8 0.9 disturbance pain (1.5 0.7 0.1, Both groups had significantly worse than group. Conclusion repetitive exhibited impaired multiple domains. Deployed TBI, but similar, less severe disruption. Future studies should explore how be related long-term deployment. Support (if any)
