Few studies, however, have assessed differences in sleep quality among premenopausal, perimenopausal, and postmenopausal women and related risk factors in Korea women. The aim of this study was to assess sleep quality and factors associated therewith according to menopausal status in Korean women.Patients and Methods: This study was based on the 2016 Korean Study of Women’s Health Related Issues (K-Stori), a cross-sectional survey employing nationally representative random sampling. In total, 3000 Korean women aged 45 to 64 years completed the Pittsburgh Sleep Quality Index (PSQI). Comparison of demographic characteristics and sleep quality among pre-, peri-, and postmenopausal women was conducted.Results: Among the participants, 26% suffered from poor sleep quality based on the PSQI. The prevalence of poor sleep quality increased with later menopausal stage (from 18.8% in the premenopausal stage to 29.5% in the postmenopausal stage P < 0.001). Multivariate logistic regression analysis showed that peri- and postmenopausal women were 1.50 and 1.73 times more likely to have poor sleep quality in comparison to premenopausal women, respectively. Chronic disease, depression, at-risk drinking, taking dietary supplements, and single women were associated with a higher likelihood of having poor sleep quality. Health status, at-risk drinking, chronic illness, dietary supplementation, and depression were significantly associated with poor sleep quality.Conclusion: Poor sleep quality appears to be prevalent in peri- and postmenopausal women in Korea. The management of sleep quality during menopause transition is important, and further research on how sleep disturbances influence the health status of women in menopausal transition is required.Keywords: menopause, sleep quality, Pittsburgh sleep quality index
