Sleep Duration and Efficiency Associated With Better Functional Exercise Capacity in Black Smokers at Risk for COPD.

ABSTRACT:

Background

Black smokers have earlier development of lung disease as well as poorer sleep health than whites.

Research question

In a sample of black smokers, to what extent does sleep health modify the association between smoking level and functional exercise capacity?

Design and methods

Cross-sectional data from 209 black smokers (≥ 1 cigarette in last month), aged 40 to 65 years with no evidence of sleep-disordered breathing (apnea-hypopnea index < 15) or severe COPD (FEV₁ > 50%), were used for the current study. Self-reported smoking rate, objectively measured sleep efficiency (SE), total sleep time (TST), and the 6-min walk test (6MWT) for functional exercise capacity were the key assessments.

Results

The mean age was 54.8 years (SD, 5.96), and m
