Abstract

Abstract: Introduction: Although neighborhood environments have been shown to affect sleep health, few studies have directly measured multiple indicators of both neighborhood deprivation and sleep while considering modification by race/ethnicity. Methods: Among 49, 833 eligible U.S. women enrolled in the Sister Study from 2003 to 2009, we investigated associations between neighborhood deprivation (e.g., percentage of residents unemployed, household crowding) and multiple sleep dimensions. Participants' addresses were linked to U.S. census block group level Area Deprivation Index rankings (range: 1–100) for the year 2000, and participant rankings were divided into quintiles where the highest quintile represented the highest deprivation level. Participants self-reported habitual sleep duration, sleep debt, frequent napping, and insomnia symptoms. Adjusting for sociodemographic and clinical characteristics, we used Poisson regression with robust variance to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) for sleep dimensions among participants within quintiles (Qs) 2–5 vs. Q1. Interaction terms were used to assess modification by race/ethnicity. Results: Mean age ± standard deviation was 55 ± 9 years. Women with higher neighborhood deprivation were more likely to self-identify as a racial/ethnic minority and had higher unadjusted prevalence of poor sleep dimensions. After adjustment, higher ADI was positively associated with very short sleep (≤5 hours), and race/ethnicity was a modifier (e.g., race-stratified results for Q5 vs. Q1:PRWhite=1.31 [95% CI: 1.14–1.51], PRBlack=0.91 [0.71–1.18], PRHispanic/Latina= 1.17 [0.68–2.04], p-interaction <0.05). Although race/ethnicity did not modify remaining associations, women with higher neighborhood deprivation also had a higher prevalence of sleep debt, frequent napping, and insomnia symptoms. When compared to White women with the lowest neighborhood deprivation, Black women across all deprivation levels and Hispanic/Latina women in Q2-Q5 were substantially more likely to report each poor sleep dimension (PR range: 1.21 to 5.01). Conclusion: A multidimensional measure of neighborhood deprivation was associated with poor sleep and sleep disparities among a diverse cohort of U.S. women. Support (if any):
