Abstract
INTRODUCTION: Nocturnal symptoms are common and important in both asthma and COPD but the relationship between sleep quality and diseases' characteristics has not been fully studied. OBJECTIVE: To compare sleep quality and daytime sleepiness in asthma and COPD patients and to explore its relation to diseases' characteristics. METHODS: In this cross-sectional study, we examined 217 consecutive asthma and COPD patients who underwent pulmonary function tests at The Center for Pathophysiology of Breathing and Sleep Medicine of The Institute for Pulmonary Diseases of Vojvodina, Sremska Kamenica, Serbia between July 2014 and January 2015. All patients completed Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). RESULTS: Study included 117 patients with asthma, 100 patients with COPD, and 102 healthy controls. There was no difference in PSQI and ESS between patients with asthma and COPD (4.9 ± 3.9 vs 5.8 ± 4.3, P = .09 and 4.8 ± 3.4 vs 4.7 ± 3.6, P = .69, respectively). PSQI and ESS did not correlate with lung function parameters. Patients with uncontrolled asthma had higher PSQI scores (uncontrolled 7.0 ± 3.7 vs partially controlled 4.6 ± 3.1 vs controlled 3.2 ± 3.7, P < .001). PSQI scores were higher in COPD group D and B compared to A and C (group D 6.9 ±4.6 vs B 6.8 ± 4.1 vs A 2.9 ± 1.3 vs C 3.1 ± 3.9, P < .001). Compared to asthma, COPD patients had longer sleep latency and used sleep regulating medications more often. CONCLUSIONS: There is no difference in sleep quality and level of daytime sleepiness between patients with asthma and COPD. Poor sleep quality is related to level of asthma control and is associated with COPD groups B and D.
