Brief Summary:
This 5-year prospective, observational study will: (1) determine the individual, social, and environmental predictors of sleep duration, quality, latency, efficiency, timing and regularity in African American smokers, (2) quantify the prospective relationship between multiple metrics of sleep with tobacco use, such that a sleep phenotype of risk for smoking is defined, and (3) examine the extent to which short sleep (<7 hrs) and other unhealthy sleep metrics, predicts lung function through smoking behaviors and inflammation, in 480 African Americans at risk for advancing COPD (GOLD Stage 0-2 and current smoker). Study subjects will be recruited via Temple Health System sites. Following eligibility screening, initially eligible subjects will provide written study consent and complete an in-home sleep assessment to rule out the exclusionary moderate-severe sleep apnea and other sleep disorders. Consenting and eligible subjects will be entered into the study and across the 60-month data collection period, complete 8 assessments: 4 annual clinical based assessments, interspersed by 4 mid-year, phone-based, self-report assessments.
