Epidemiology and Risk Factors of Menopause Syndrome Among Uyghur, Han, and Kazak Women in Xinjiang, China.

BACKGROUND This study analyzed the epidemiology and the risk factors of menopause syndrome (MPS) among Uyghur, Han, and Kazak women in Xinjiang. MATERIAL AND METHODS This was a cross-sectional study. The stratified-cluster random-sampling method was used. A total of 3382 women aged 40 to 60 years of age were included from Urumqi City, Kashgar City, Altay City, Ili Kazakh Autonomous Prefecture, Künes County, Mongolkure County, Tekes County,Talede town, Alemale Township, and Ulugchat County (Kashgar Prefecture) in Xinjiang Province. A questionnaire was used to survey the clinical characteristics of MPS. Logistic regression analysis was used to analyze the MPS risk factors among Uyghur, Han, and Kazak women. RESULTS Oral contraceptives, negative life events, and menopause stages can influence MPS in Han women. In addition, occupation, body weight, mental illness, drug or alcohol abuse, and income level also affect the MPS of Uyghur women. In contrast to Han and Uyghur participants, education, menopausal pattern (natural or artificial), reproductive factors, and smoking are risk factors of MPS in Kazakh women. CONCLUSIONS The menopausal stages and the risk factors for MPS are different among Uyghur, Han, and Kazak women.
