Greater perceived neighborhood disorder was associated with greater wake after sleep onset, less sleep maintenance efficiency, and increased odds of insomnia symptom severity >=10 (OR 1.04, p=0.008).
Observational (n=223)
Are objective and subjective neighborhood factors associated with actigraphic sleep health and insomnia symptoms in middle-aged adults?
Poor subjective and objective neighborhood characteristics are associated with worse actigraphic sleep and higher insomnia severity, with differences observed by race.
Effect estimate: OR 1.04
p-value: p=0.008
Abstract Introduction Empirical evidence supports an association between poor neighborhood characteristics and poor sleep. However, limited studies have explored the influence of neighborhood factors in observed Black/White differences in actigraphic sleep and self-reported insomnia. We examined objective/ subjective neighborhood factors related to actigraphic sleep health and insomnia symptoms and the moderating role of race. Methods The sample (N=223) included adults (Mage=62; 67% Black race; 70% female, 64% above poverty threshold) enrolled in the Healthy Aging in Neighborhoods of Diversity across the Life Span Sleep (HANDLSleep) study. Subjective neighborhood quality was assessed using three neighborhood scales (i.e., perceived disorder, cohesion, and social control). Objective neighborhood quality was assessed with the Neighborhood Atlas Area Deprivation Index (ADI). Actigraphic sleep was assessed across 7 days and captured sleep onset, sleep onset variability, total sleep time (TST), wake after sleep onset (WASO) and sleep maintenance efficiency (SMEff). Insomnia symptom severity was assessed with the Insomnia Severity Index (ISI). Linear and logistic regression models were conducted to test the study aims and adjusted for demographic covariates (e.g., age, sex, and poverty status). Results Greater perceived neighborhood disorder was associated with greater actigraphic WASO (b=0.57, SE=0.19, p=.003) and less SMEff (b=-0.07, SE=0.03, p=.030), and an increased odds of insomnia symptom severity =10 (OR=1.04, SE=0.02, p=.008). Higher perceived neighborhood social cohesion and social control was associated with less WASO (b=-1.11, SE=0.34, p=.001; b=-1.40, SE=0.46, p=.003) and greater SMEff (b=0.14, SE=0.06, p= .010; b=0.20, SE=0.08, p=.01) and a decreased odds of insomnia symptom severity (OR=0.93, SE = 0.02, p=.010; OR=0.91, SE=0.03, p=.010). Strictly among Black adults, higher neighborhood social control was significantly associated with a decreased odds of having an insomnia symptom severity =10 (OR = 0.86, CI = 0.78-0.95). Strictly among White adults, residing in a more socioeconomically disadvantaged neighborhood was associated with an increased odds of having insomnia symptom severity =10 (OR = 1.46, CI = 1.02-2.08). Conclusion These results demonstrate racial differences in associations between neighborhood characteristics and sleep, mechanisms of which should be further examined to strengthen the efficacy of mitigating sleep health issues. These findings motivate future research on altering neighborhood conditions to improve sleep health. Support (if any) Z01–AG000194/UF1-AG072619, UF1-AG072619
Dadzie et al. (Fri,) conducted a observational in Sleep health and insomnia (n=223). Objective and subjective neighborhood factors was evaluated on Insomnia symptom severity >=10 associated with perceived neighborhood disorder (OR 1.04, p=0.008). Greater perceived neighborhood disorder was associated with greater wake after sleep onset, less sleep maintenance efficiency, and increased odds of insomnia symptom severity >=10 (OR 1.04, p=0.008).
