Low sleep quality appears to worsen in COPD patients as their breathing problems progress and may deteriorate the patient’s quality of life.

Stepwise multiple regression analysis showed that severity of COPD (r2=0.11, P<0.001) being a woman (r2=0.20, P<0.004) and sleep quality (r2=0.16, P<0.0001) were all associated with decreasing quality of life among people with COPD, said Krishna Sharma, MD, of Eternal Heart Care Center, Jaipur, India.

In his oral presentation at CHEST 2016, the annual meeting of the American College of Chest Physicians, Sharma said, “Our data suggest and extend previous studies showing that quality of sleep is a major determinant of quality of life in COPD. Increased efforts to diagnose and treat sleep problems, including measures to improve factors that adversely effect sleep should receive more attention in the daily management of these patients.

“There was significant impact of poor sleep quality in stable COPD patients on the health-related quality of life and it was more pronounced in women,” he said. “Quality of sleep in patients with COPD is poor and worsens with disease progression. The low quality of sleep has an effect on the deterioration of their quality of life, especially in female patients.”

He said that previous studies have shown that studies indicate that poor sleep quality is a correlate of health-related quality of life in COPD. “To date, however, there are few studies detailing the relationship between sleep quality and health-related quality of life in COPD and this had not been previously investigated in these individuals from our region,” he said.
