Background: Sleep disorder is a common problem in adults and affects physical and mental health. We investigated factors associated with poor sleep quality in Korean primary care. Methods: A total of 129 couples (129 husbands and 129 wives) aged 30 to 79 years were included in this study from March, 2009 to February, 2010. The subjects were surveyed using a specific questionnaire. Sleep disorder was defined by a Pittsburgh Sleep Quality Index global score greater than 5 (poor sleepers). The subjects were divided into a group of good sleepers (n = 160) and a group of poor sleepers (n = 98). Socio-demographic and clinical covariates including age, sex, depression, spouse sleep disorder, and spouse depression were reported. Results: Poor sleep quality was present in 38.0% of total subjects. According to chi-square test results, female, patients with depression, and low sleep quality of spouse were significantly associated with sleep disorder. In multivariate logistic regression analysis, depression increased the risk of poor sleep quality (odds ratio [OR], 7.775; 95% confidence interval [CI], 2.555 to 23.661), and non-risky drinking decreased the risk of poor sleep quality (OR, 0.343; 95% CI, 0.128 to 0.924). Conclusion: In our study, more than one-third of participants had poor sleep quality. Depression was a strong independent factor associated with sleep problems.
