721-P: Mood and Sleep in Young Adults with Type 1 Diabetes

Abstract

Introduction: Depression is linked with sleep problems and for people with T1D, mood concerns and sleep are associated with A1c. There are psychosocial and sleep challenges in young adulthood, yet their associations are unknown in racially/ethnically diverse young adults with T1D. We aimed to evaluate general mood and T1D-specific mood in relation to sleep in young adults with T1D, controlling for relevant medical and demographic factors. We hypothesized that depressive symptoms and T1D distress would explain the greatest variance in sleep outcomes. Methods: Young adults with T1D (n=83, M age=19.9±1.3 yrs, M A1c=8.9±2.0%) self-reported on sleep, T1D distress, depressive symptoms, race/ethnicity, insurance status and device use at baseline of a behavioral trial. Hierarchical regression models evaluated factors related to sleep quality and duration. Results: Participants reported M=7.1±1.4 (range: 4-12) hrs sleep/night and 28% described their sleep as fairly-very bad. As detailed in the Table, only greater diabetes distress was significantly associated with worse sleep quality. No factors significantly related to duration. Conclusions: Despite sleeping near the target 7-9 hrs/night, the centrality of diabetes distress for young adults’ perceived sleep quality highlights its importance beyond commonly related medical and demographic factors. Clinical attention to T1D-specific mood concerns may benefit sleep health during young adulthood. Disclosure S.A.Carreon: None. M.E.Hilliard: None. C.G.Minard: None. S.Lyons: None. R.Streisand: None.
