Ambient Air Pollution Exposure and Sleep Quality in COPD

Rationale: Ambient air pollution exposure is associated with respiratory morbidity among individuals with chronic obstructive pulmonary disease (COPD), particularly among those with concomitant obesity. Although people with COPD report high incidence of poor sleep quality, no studies have evaluated the association between air pollution exposure, obesity, and sleep disturbances in COPD. Methods: ) and 1-year ozone (1Yr-ozone) with the PSQI score, and whether obesity modified the association. Results: =0.51). There was no association between 1 Yr-ozone and PSQI. Conclusions: may be modifiable risk factors to improve sleep quality.
