Sleep Disorders as Predictor of Health-Related Quality of Life in Patients with COPD

Abstract

Objectives: Chronic Obstructive Pulmonary Disease (COPD) patients often suffer from poor sleep and health-related quality of life (HRQoL). The purpose of the current study was to find out the frequency of sleep disorders in COPD patients and to examine their role in predicting health-related quality of life after accounting for demographics and COPD disease severity. Method: It was a cross sectional analytical study and the sample consisted of 150 COPD patients with age ranging from 40-70 years selected through non-probability convenient sampling technique. Sleep disorders scale and WHO quality of life scale were used to collect data from a pulmonary clinic of Lahore. Results: The results revealed that sleep disorders were present in 47 (31%)patients. Sleep disorders were a significant predictor of HRQoL in COPD patients and hierarchical multiple regression model revealed insomnia(p<05), hypersomnia (p<.01), restless legs syndrome(p<.05), and sleep-related breathing disorder(p<.01) to contribute significantly to different dimensions of HRQoL.
Conclusion: Sleep disorders are quite prevalent in COPD patients and this study ascertains the need for timely screening and management of sleep disorders in patients for enhanced quality of life.
