0256 Child Maltreatment and Multidimensional Sleep Health among Incoming First-Year College Students

Abstract Introduction Despite the growing body of evidence linking child maltreatment to compromised sleep health in adulthood, links in emerging adults are understudied. We examined associations between child maltreatment (CM) and multidimensional sleep health among emerging adults undergoing the major life transition of starting college. Methods First-year college students (N=682, 41% male, 48% Non-Hispanic White, 22% Non-Hispanic Asian, 15% Hispanic all races, 6% Non-Hispanic Black, and 9% Non-Hispanic other races) completed daily sleep diaries (DSDs) for 9 weeks, and completed the Childhood Trauma Questionnaire (CTQ), Epworth Sleepiness Scale (ESS), and Pittsburgh Sleep Quality Index (PSQI) following DSD completion. We used linear regression models to examine associations between CTQ-derived CM (0=none, 1=any [moderate to severe emotional abuse/neglect, physical abuse/neglect, or sexual abuse]) and sleep health (Buysse, 2014) using a multidimensional score encompassing components from the RUSATED model (regularity [DSD sleep midpoint SD: 0= >1 hour, 1= ≤1 hour], satisfaction [PSQI sleep quality item: 0=fairly or very bad, 1=very or fairly good], alertness [ESS score: 0= >10, 1= ≤10], timing [DSD sleep midpoint: 0= <3:30 or >5:30, 1= ≥3:30 and ≤5:30], efficiency [DSD sleep efficiency: 0= <93%, 1= ≥93%], and duration [DSD sleep duration: 0= <7 hours or >10 hours, 1= ≥7 hours and ≤10 hours]. Results In the full sample 20.5% reported CM (within-group prevalences: females 21%, males 20%, Non-Hispanic Whites 12%, Non-Hispanic Asians 28%, Hispanics of all races 26%, Non-Hispanic Blacks 34%, and Non-Hispanics of other races 30%). Those with CM had significantly worse sleep health (B=-0.25, 95% CI=-0.46, -0.04) compared to those without CM, but not after adjustment for sex and race/ethnicity. In logistic regression models, the only individual sleep health component significantly associated with CM was sleep satisfaction. After adjustment for sex, race/ethnicity, and depressive symptoms, those who experienced CM had a 52% lower odds of reporting good sleep quality (OR=0.48, 95% CI=0.30, 0.76). Conclusion CM is associated with worse sleep satisfaction among first-year college students, which aligns with previous research in older adults. Additional research should examine neurophysiological correlates of sleep satisfaction in the context of child maltreatment and effects on subsequent health.
