0162 Preliminary Findings on the Moderating Effects of Exercise on Alcohol and Sleep

Abstract Introduction We sought to gauge how sleep was being affected by alcohol and how other factors that affect may contribute to sleep impairments may be moderated by exercise. Methods The overall sample comprised of 743 Black or African American participants from the New York City or the South Florida area from NIH funded studies called ESSENTIAL and MOSAIC. This data was collected from January 2020 to November 2023. A wearable device called Fitbit was used to capture steps. The baseline assessment comprised of questions about the frequency of substance use, Insomnia Severity Index, PROMIS Sleep Disturbance 8a, the Sleep Related Impairment 8a, Everyday Discrimination Scale, Assessment of Sleep Environment, and Holmes-Rahe Stress Inventory. To find the homogeneity of variances between groups, a Levene's test was performed between alcohol and a variety of factors that affect sleep. Results In the participant pool (n=743), 57% were female(n=424) and 43% were male(n=221). 27% of participants lived in the New York City area and 73% of participants lived in the South Florida area. 603 participants having at least one drink a month for all data captured in the baseline assessment. We carried out Levene's test statistic for stress (t=–8.408, df=741, m=.95, sd=1.076), everyday discrimination (t= –18.642, df=741, m=39.9, sd=12.846), sleep disturbance (t= –5.644, df=741, m=4.51, sd=9.441), insomnia (t= –11.899, df=741, m=10.24, sd=6.973), sleep environment (t= –42.931, df=741, m=39.43, sd=.572). The p-value was <.001 so there was a significant difference in variance between alcohol and each factor. For steps, 222 out of 234 participants reported at least one drink a month. We carried out Levene's test statistic for sleep disturbance (t= 7555.4862, sd= 4150.84545). The p-value was .040 so there was a significant difference in variance between alcohol and steps. Conclusion In South Florida and New York, alcohol consumption was associated with variance in sleep disturbance, sleep impairment, and insomnia symptoms. Alcohol consumption was associated with variance as sleep environment, stress, and discrimination. Support (if any) NIH R25HL-10-5444 R01HL142066, R01AG067523.
