Sleep Quality and Associated Factors in Premenopausal, Perimenopausal, and Postmenopausal Women in Korea: Findings from the K-Stori 2016

Abstract

Poor sleep quality is a common problem among middle-aged women. 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.

Factors associated with poor sleep quality in midlife Singaporean women: The Integrated Women’s Health program (IWHP)

“…The prevalence of poor sleep quality (38.2%) in our study concurs with findings from the SWAN study in U.S. (38.0%, n = 12,603 women, aged 40–55 years) [ 7 ]. However, our prevalence of 38.2% was higher than a Hong Kong study (26.0%, n = 305 women, mean age: 50.1 years) [ 15 ] as well as a Korean study (26.0%, n = 3000 women, n = 45–64 years) [ 16 ]. In Singapore, poor sleep quality was previously reported at a lower prevalence of 27.0% [ 4 ], possibly due a younger age range and inclusion of both men and women in that study.…”

“…These include the U.S.-based Study of Women’s Health Across the Nation (SWAN) [ 10 ], and a large study of midlife women from 11 Latin American countries [ 8 ]. Anxiety and depression have also been linked to poor sleep quality [ 7 , 8 , [11] , [12] , [13] , [15] , [16] , [17] ]. Self-reported depression was associated with poor sleep outcomes (insomnia, sleep disturbances, restless sleep) among participants from the Seattle Midlife Women’s Health Study [ 11 ].…”

“…Self-reported depression was associated with poor sleep outcomes (insomnia, sleep disturbances, restless sleep) among participants from the Seattle Midlife Women’s Health Study [ 11 ]. Most sleep studies among midlife women to date have been conducted in Caucasian populations [ 7 , 8 , [10] , [11] , [12] , [13] , 17 ], while studies in Asian women have been small and non-representative [ 14 , 15 ], not specific to midlife [ 4 , 18 ], or were conducted in ethnically homogeneous Asian populations [ 16 , 19 ].…”

Prevalence and risk factors for depressive and anxiety symptoms in middle-aged Chinese women: a community-based cross-sectional study

“…Previous evidence has indicated that symptoms of depression and anxiety are associated with increased risk of cardiovascular diseases, osteoporosis and osteoporotic fractures that substantially affected morbidity and mortality for middle-aged women [6][7][8][9][10]. In addition, both depressive and anxiety symptoms have a deleterious influence on women's quality of life, sleep quality and life satisfaction during perimenopause [11][12][13].…”

“…You may have physical discomfort, be worried or anxious, or perhaps be experiencing hormonal fluctuations. Perimenopausal symptoms such as hot flashes can affect sleep patterns 30,31. Some medications may also affect your sleep.…”
