Multicenter study showed that sleep disorders was diagnosed in approximately 40% of patients with chronic obstructive pulmonary disease. COPD is a condition that is most widely investigated regarding its relation with sleep.

Our study is a complementarily one that is carried out to determine how COPD affects the quality of sleep.

This study enrolled 300 patients with COPD, who receive treatment in an occupational diseases hospital of ministry of health, Turkey, and control group of 100 healthy volunteers. This definitive, cross-section study was conducted between 01.02.2016–31.04.2016. Socio-demographic details form, epworth sleepiness scale and Pittsburgh sleep quality index are used to gather the study data. Any disease that affects sleep structure (Obstructive sleep apnea syndrome, substance abuse, irritable leg syndrome, depression, anxiety disorder, peptic ulcer) and a treatment that can affect sleep patterns (antidepressant, anxiolytic, diuretic) and to work all patients who were planned to receive Hamilton depression and were assessed with anxiety scale and anxiety, depression those who have high points to think of the reins are not included in the study.

Score obtained from Pittsburgh sleep quality index–A subjective test - was significantly high in the COPD group. Actigraphic sleep parameters that include ‘actual wake time’, ‘actual wake %’, ‘total activation score’ and ‘fragmentation index’ were significantly high in the COPD group comparing to control group. Among actigraphic sleep parameters, ‘actual sleep time’, ‘actual sleep’ and ‘sleep efficiency’ were significantly lower in the COPD group comparing to control group.

The study demonstrates that chronic obstructive pulmonary disease poses negative influence on the quality of sleep and leads to sleep disorders.
