0161 Preliminary Findings on the Moderating Effects of Exercise on Tobacco Use and Sleep

Abstract Introduction It is widely understood that the use of tobacco has negative effects on several health outcomes such as sleep disturbances. With all the readily available information concerning these negative factors, there is still a significant use of tobacco amount Black and African American individuals in the United States. This study aims to find any correlation between sleep, exercise, and tobacco use amongst this population. Methods A comprehensive statistical analysis was performed using the combined data of both MOSAIC (n=267) and ESSENTIAL’s (n=476) data. These are NIH funded studies that are currently active and being conducted. These studies comprised only of Black or African American (n=221 Male; n=424 Female) individuals living in South Florida or New York. Among the 743 participants, 207 reported having smoked at least 100 cigarettes in their life vs non- smokers (n=404). Participants in both the MOSAIC and ESSENTIAL study followed similar procedures. A self-reported baseline survey in Phase 1 consisting of several assessments such as: The Holmes-Rahe Stress score(SS), Everyday Discrimination Scale (EDS), Sleep Disturbances (SD), Insomnia Severity Index (ISI), and Assessment of Sleep Environment (ASE) were used for these findings. Phase 2 consisted of wearing several sleep devices for a 7-day period. Of these devices we utilized the objective data found in the Fitbit activity counter for steps taken. Results Of the 743 participants significant t-test values were observed across previously mentioned parameters. With significant findings across the mean scores of the following variables; SS (t=-8.408 , df= 741, p<.001), EDS(t=-18.642, df=741, p<.001), SD(t=-5.644, df=741, p<.001), ISI (t=-11.899, df=741, p<.001), ASE (t=-42.931, df=741, p<.001), and Fitbit Steps (t=-.922,df=232, p=.040). No significant or strong associations were found in a regression linear analysis between steps, ISI, and tobacco use. Conclusion Differences in mean scores were found to be significant amongst these variables. Although these results were significant, future research is necessary to find if exercise may have a moderating effect on tobacco use and sleep. Support (if any) NIH R01HL142066 R01AG067523
