INCREASED SLEEP EFFICIENCY ASSOCIATED WITH INCREASED LUNG FUNCTION IN AFRICAN AMERICAN LIGHT SMOKERS: RESULTS FROM A PROSPECTIVE COHORT EXAMINATION

TYPE: Abstract Publication TOPIC: Obstructive Lung Diseases PURPOSE: We tested the extent to which improvements in sleep efficiency (percentage of time in bed, asleep) predicted improvements in lung function (FEV1/FVC ratio) in African American (AA) smokers. METHODS: Prospective data from 70 AA smokers, 40-65 years with Apnea–Hypopnea Index (AHI) <15 or mild COPD (FEV1>50%), were enrolled. Change in the FEV1/FVC ratio (measured by spiromotery)...
