The objective of this study was to examine neighborhood safety in childhood as a mediator of subsequent racial disparities in sleep.<h4>Methods</h4>Data were from Black and White young adults attending a large, predominantly White university in the Southeastern United States (N = 263; 52% Black, 53% female; Mean age = 19.21 years, SD = 1.01). Sleep parameters were assessed from eight nights of wrist actigraphy (time in bed, sleep duration, and efficiency) and an established self-report measure of daytime sleepiness. Residential histories from birth through age 18 were documented, and retrospective Sleep medicineRacial disparities in sleep health between Black and White young adults: The role of neighborhood safety in childhood.PMC8096683R15 HL140504K01 HL147998Chae DHNichols OIRobinson ATBoylan JMFuller-Rowell TEEl-Sheikh MfalseRacial disparities in sleep health between Black and White young adults: The role of neighborhood safety in childhood.<h4>Objectives</h4>Black adults in the United States have shorter sleep durations and poorer sleep efficiency relative to White adults, yet reasons for these disparities are not well explicated.
