Sleep quality is often poor in patients with COPD. However, these night-time symptoms are frequently unnoticed. The goal of the current study was to investigate the relationship between sleep quality, symptoms, and lung function in COPD patients [1].
A descriptive, analytic study with a cross-sectional design was conducted in COPD patients in the Harum Melati Clinic (Indonesia). Spirometry was performed to measure lung function, modified British Medical Research Council (mMRC) questionnaires were used to report symptoms, and sleep quality was quantified using the Pittsburgh Sleep Quality Index (PSQI) scale and stratified into good (PSQI score <5) and poor sleep quality (PSQI score >5). Spearman correlation was used to measure the strength of the correlation between variables.
The study included 203 subjects; most patients were male, and medium age was 62.4 years. Of investigated patients, 114 (71%) had good sleep quality and 59 (29%) had poor sleep quality. A moderate positive correlation was found between sleep quality and COPD symptoms (ρ=0.437; P=0.001), while a strong positive correlation was found between sleep quality and lung function (ρ=0.879; P=0.001).
Taken together, sleep quality in COPD patients correlated to symptoms and lung function. More research on diagnosis and treatment of sleep problems in COPD patients should be done to manage daily life of these patients.
