Abstract To investigate the prevalence and risk factors of polycystic ovary syndrome (PCOS) among women of childbearing age in Qionghai area. Methods: The epidemiological random sampling method was used for PCOS investigation by randomly selected 1600 childbearing age women aged 20-45 years in Qionghai area from January 2018 to January 2020. The women with confirmed PCOS were included in study group and the other women were included in control group. The baseline data of the women were compared between the two groups, and the risk factors of PCOS were analyzed. Results: 1572 (98.3%) valid questionnaires were returned, 95 women with PCOS were confirmed with 6.0% prevalence. Among the women with PCOS, the percentage of clinical manifestations from high to low was waist circumference >80cm (38.95%), acne (34.7%), amenorrhea (26.3%), menstruation (25.3%), overweight (24.2%), infertility (22.1%), hypertrichosis (23.2%), and obesity (6.3%). Multivariate logistic regression analysis showed that family history of diabetes, early or late menarche, maternal infertility, and high body mass index were the risk factors of childbearing age women with PCOS (P<0.05). Conclusion: The clinical manifestations of childbearing age women with PCOS in Qionghai area are mainly irregular menstruation, amenorrhea, infertility, acne, hirsute, and obesity. Family history of diabetes, early or late menarche, maternal infertility and high body mass index are the risk factors of childbearing age women with PCOS. It is suggested that the prevention and control measurement for PCOS should be carried out based on these characteristics.
