Abstract

Study Objectives: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and may frequently be associated with sleep disturbances. However, the correlates of insomnia in COPD patients have not been well characterized. The aim of the current study was to describe the prevalence of insomnia disorder in COPD and to elucidate the demographic and clinical characteristics of COPD patients that are associated with insomnia. Design: Cross-sectional study. Setting: Clinic-based sample from an academic hospital. Participants: Patients with stable COPD. Measurements: An interviewer-conducted survey was administered to 183 participants with COPD. Seventy-two of these participants (30 with and 42 without insomnia) maintained a sleep diary and underwent actigraphy for 7 days. Results: Insomnia (chronic sleep disturbance associated with impaired daytime functioning) was present in 27.3% of participants. Current tobacco users (odds ratio (OR), 2.13) and those with frequent sadness/anxiety (OR, 3.57) had higher odds, but oxygen use was associated with lower odds (OR, 0.35) of insomnia. Patients with insomnia had worse quality of life and a higher prevalence of daytime sleepiness. Actigraphy revealed shorter sleep duration and lower sleep efficiency, and a sleep diary revealed worse self-reported sleep quality in participants with insomnia. Conclusion: Insomnia disorder is highly prevalent in patients with COPD; current tobacco use and sadness/anxiety are associated with a higher prevalence, and oxygen use with a lower prevalence of insomnia; patients with insomnia have poorer quality of life and increased daytime sleepiness; and insomnia is associated with worse objective sleep quality.
