Neighborhood disadvantage, perceived stress, and systolic blood pressure were associated with shorter sleep durations, with Stage 2 sleep being particularly sensitive to structural disadvantage.

Do neighborhood disadvantage and perceived stress reduce sleep duration in adults?
Neighborhood disadvantage and perceived stress are associated with shorter sleep durations, highlighting the impact of socioenvironmental factors on sleep health.
Objectives/Goals: Sleep is a useful intervention target to improve mental and physical health. Yet, the contextual factors that impact sleep in real-life settings are poorly understood. We assessed how psychological and socioenvironmental factors influence self-reported sleep in a large, US sample (Study 1) and sleep physiology in a prospective cohort (Study 2). Methods/Study Population: Study 1: 13,483 participants (63% males, mean age 46, 24% non-White) completed on-demand blood pressure (BP), self-reported stress, physical health, and sleep duration assessments for 3 weeks. Study 2: 42 Black adults (23% males, mean age 42) completed up to six ambulatory sleep recordings at home for 2 weeks. Stage durations for rapid eye movement (REM) and non-REM Stages 1, 2, and 3 were determined. Daily self-reports of stress and physical health were also gathered. For both studies, residence zip codes were linked to a national database to quantify neighborhood factors (i.e., built environment, poverty, social cohesion, etc.). Multiple linear regressions and mixed-effect models assessed whether neighborhood factors, demographics, health indices, and stress could predict sleep durations. Results/Anticipated Results: In Study 1, neighborhood disadvantage, perceived stress, and systolic BP were associated with shorter sleep durations. Better self-reported health predicted longer sleep durations. Black, Native, Latino/as, and Pacific Islander participants had shorter sleep durations, whereas White participants had longer sleep durations. An interaction between perceived stress intensity and health indicated that better health (+1SD) protected sleep from increasing stress. Preliminary analyses in 26 participants from Study 2 revealed that neighborhood disadvantage and self-reported poor health are associated with shorter Stage 2 sleep durations. However, daily stress did not predict stage durations, and no interactions emerged. Discussion/Significance of Impact: Neighborhood disadvantage led to short sleep in two studies, with novel findings indicating that Stage 2 durations may be most sensitive to structural disadvantage. Interventions that invest in material resources to reduce neighborhood inequities may be an innovative approach to protect sleep and mitigate related illness.
Silva-Jones et al. (Wed,) conducted a observational in Sleep duration (n=13,525). Neighborhood disadvantage, stress, and health was evaluated on Sleep duration (self-reported and physiological stage durations). Neighborhood disadvantage, perceived stress, and systolic blood pressure were associated with shorter sleep durations, with Stage 2 sleep being particularly sensitive to structural disadvantage.
