The incidence of hypertensive disorders complicating pregnancy (HDCP) in patients with polycystic ovary syndrome (PCOS) is relatively high, with factors like age, BMI, family history of hypertension, history of adverse pregnancy, history of contraceptive pills use, and family history of HDCP being identified as independent risk factors. Early prevention and intervention measures targeting these risk factors can help reduce the occurrence of HDCP in PCOS patients.
Background: The hypertensive disorders complicating pregnancy (HDCP) is common in patients with polycystic ovary syndrome (PCOS), yet the potential influencing factors remained unclear. We aimed to assess the independent risk factors of HDCP in patients with PCOS, to provide clinical evidences for the management of PCOS. Methods: Pregnant PCOS patients treated in our hospital from June 1, 2018 to November 30, 2020 were approached. The personal and clinical characteristics of patients with and without gestational hypertension were evaluated. Logistic regressions were conducted to identify the independent risk factors of HDCP, Receiver operating characteristics (ROC)curve analysis was conducted to evaluate the predicting value. Results: A total of 188 PCOS patients were included, the incidence of HDCP in patients with PCOS was 27.66 %. There were significant differences in the age, BMI, family history of hypertension, the history of adverse pregnancy, history of contraceptive pills use and family history of HDCP between HDCP group and no-HDCP group (all p < 0.05), and there were no significant differences in the family history of diabetes, multiple pregnancy and long-term smoking history between HDCP group and no-HDCP group (all p > 0.05). Age >= 27y(OR2.048, 95 %CI1.121 similar to 3.208), BMI >= 24 kg/m(2)(OR1.463, 95 %CI1.069 similar to 2.011), family history of hypertension(OR2.129, 95 %CI1.093 similar to 3.042), the history of adverse pregnancy(OR2.435, 95 %CI1.264 similar to 4.085), history of contraceptive pills use(OR3.806, 95 %CI1.184 similar to 6.102), family history of HDCP(OR1.934, 95 %CI1.016 similar to 2.774) were the independent risk factors of HDCP in patients with PCOS (all p < 0.05). ROC curve analyses indicated that those factors had good predictive value on HDCP in PCOS patients. Conclusions: The incidence of HDCP in PCOS patients is relatively high. In clinical practice, medical workers should carry out early prevention and intervention measures for these risk factors to reduce the incidence of HDCP.
