0129 Perceived Stress and Revenge Bedtime Procrastination in Black Adults

Abstract Introduction “Revenge bedtime procrastination”, the intentional delay of bedtime to engage in leisure activities or tasks not accomplished during the day, has been increasingly recognized as a contributor to poor sleep health. However, no studies have examined psychosocial factors associated with bedtime procrastination among Black adults, a population disproportionately exposed to psychosocial stressors and at an increased risk for insufficient sleep. In this study, we examined the association between psychosocial stressors and frequent engagement in revenge bedtime procrastination among Black adults. Methods We analyzed data from the SLUMBR study, a cross-sectional study examining perceptions, attitudes, and beliefs around sleep practices in Black adults (N= 359, 49% women, aged 18-50). Perceived stress was measured via the Global Perceived Stress Scale (GPSS), which assessed stress in the past 12 months across eight domains: job, relationships, neighborhood, caregiving, legal problems, medical problems, racism/discrimination, and meeting basic needs. The total GPSS score was categorized into tertiles (low, medium, high). For analyses examining individual stressors of the GPSS, responses were dichotomized to no/low stress versus moderate/high stress. Participants responded to a single item assessing how often they participated in bedtime procrastination, which we dichotomized as never/rarely/sometimes versus often/always. Poisson regression models with robust estimators examined the association of perceived stress (total stress and eight stressors) and bedtime procrastination, adjusting for age, sex, income, education, employment, and partner status. Results Approximately 34% of participants reported participating in revenge bedtime procrastination often/always. In fully adjusted models, high (vs. low) perceived stress was associated with a greater prevalence of frequent revenge bedtime procrastination (PR: 1.86 CI: 1.16, 2.97). In domain-specific analyses, moderate/high relationship and caregiving stress were associated with increased prevalence of frequent bedtime procrastination (PR: 1.91 CI: [1.30, 2.82]; PR: 1.54 CI: 1.03, 2.30). Conclusion High levels of perceived stress were associated with frequent revenge bedtime procrastination. Individuals experiencing moderate/high levels of relationship and caregiving stress were more likely to engage in revenge bedtime procrastination. While cross-sectional, findings suggest that interventions to address revenge bedtime procrastination should consider addressing stressors that may contribute to delaying bedtime.
