Abstract

Objectives:To examine the prevalence and risk factors of menopausal symptoms in middle-aged Chinese women.Methods:A cross-sectional, community-based study recruited 6,745 women aged 40 to 55years in the eastern, central, and western regions of China during 2018. Menopausal status was categorized into reproductive stage (defined as regular menstruation or subtle changes in menstrual cycle characteristics), menopausal transition (the beginning of a persistent difference of 7d in the length of consecutive cycles, or the last menstruation having occurred no more than 12mo), or postmenpause (the end of the 12mo period of amenorrhea) according to the Stages of Reproductive Aging Workshop classification. Menopausal symptoms were determined by the modified Kupperman Menopausal Index (KMI) questionnaire and considered nonmenopausal symptoms (total KMI score<15) and menopausal symptoms (total KMI score≥15). Demographic, lifestyle, physical, and menopausal characteristics were collected by face-to-face interviews. Logistic regression models were used to identify factors associated with the risk of menopausal symptoms.Results:Among all participants, the mean age was 46.9years, and 15.7% (1,001/6,364) of participants reported experiencing menopausal symptoms. The prevalence of menopausal symptoms was 9.3% (303/3,256), 23.9% (293/1,227), and 21.5% (405/1,881) in the reproductive stage, menopausal transition, and postmenopausal stage, respectively. Overall, the three most prevalent menopausal symptoms were insomnia (44.7%), fatigue (40.4%), and mood swings (37.2%). The multivariable logistic regression model showed that menopausal status, residence, nulliparity, and chronic diseases were associated with the risk of menopausal symptoms (all P<0.05). Women during menopausal transition (OR=2.66, 95% CI: 2.21-3.20) or postmenopause (OR=2.26, 95% CI: 1.82-2.80) had significantly increased risk of menopausal symptoms compared with those in the reproductive stage.Conclusions:Menopausal status, residence, nulliparity, and chronic diseases were associated with menopausal symptoms in middle-aged Chinese women.
