0259 Sleep Duration Associated with Perceived Racial Discrimination: Data from 25 US States

Abstract Introduction Previous studies have shown sleep duration associated with racism, but few studies have examined population-level data and how these relationships differentiate across race/ethnicity groups. Methods Data from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) was used. The BRFSS is a state-based population survey conducted annually by the CDC. In 2022, 25 states collected data on perceived discrimination (N=144.267), which was assessed with the question: “Within the past 12 months, do you feel that in general you were treated worse than, the same as, or better than people of other races?” As well as the same question regarding treatment at work and when seeking healthcare, and whether individuals experienced physical symptoms due to race-based treatment. Response options were Same (reference), Better, or Worse. Habitual sleep duration was categorized as =4h, 5h, 6h, 7h (reference), 8h, 9h, and 10+h. Sleep-by-race/ethnicity interactions were explored. Models were adjusted for age, sex, education, and depression, and were population-weighted. Results Decreased likelihood of perceived better treatment was associated with =4h, 5h, 6h, and 8h, increased likelihood of worse treatment was associated with =4h, 5h, and 6h, and decreased likelihood was associated with 8h and 9h. Sleep-by-race/ethnicity interaction was significant (p 0.0001). In stratified analyses, among Non-Hispanic Whites, insufficient and excessive sleep were both associated with perceived racism. Among Blacks/African-Americans, longer sleep duration was associated with perceived better treatment and insufficient sleep was associated with worse treatment. Among Hispanics/Latinos, 9h sleep was associated with perceived better treatment, but insufficient sleep was associated with worse treatment. Among Asians, worse treatment was associated with 10+h only. Among American Indians/Alaskan Natives, worse treatment was associated with all categories of insufficient sleep. Similar sleep-by-race/ethnicity interactions were found for treatment in work (p 0.0001) and healthcare settings (p 0.0001). Although no sleep-by-race/ethnicity interaction was found, physical symptoms due to treatment based on race was associated with =4h (OR=2.28), 5h (OR=1.93), and 6h (OR=1.27). Conclusion Insufficient (and in some cases excessive) sleep duration is associated with increased perceived discrimination across groups and settings, though groups differ in terms of degree of impact. Insufficient sleep is also associated with increased physical symptoms due to racism. Support (if any)
