Three specific aims will determine: contributions of sleep timing and sleep quality and quantity to racial disparities in smoking status (Aim 1), objective sleep characteristics and smoking behavior among blacks and whites who smoke cigarettes (Aim 2), and whether sleep restriction modifies craving and withdrawal in racially diverse smokers (Aim 3). Specifically, we will utilize self-report questionnaires, objective measures of sleep quality and timing (actigraphy) and circadian phase (dim light melatonin onset), as well as ecological momentary assessment of cigarette use, smoking urges, cravings, and withdrawal symptoms to identify circadian and sleep characteristics that are most strongly associated with smoking status, heaviness of smoking and dependence among blacks and whites. Finally, we will test whether acute sleep restriction (4 hours of time-in-bed) versus sleep extension (10 hours of time-in-bed) modifies craving and withdrawal symptoms following cessation in black and white smokers. If successful, the results of this study will result in identification of circadian dysfunction and insufficient sleep as mechanisms that underlie the association between sleep and cigarette smoking behaviors and dependence in diverse populations. Moreover, these findings are likely to inform clinicians of the importance of sleep and sleep timing on cigarette smoking behaviors and dependence that will help in the development of novel interventions to reduce morbidity and mortality caused by tobacco use.
