Abstract
OBJECTIVES: Hypertensive disorders complicating pregnancy is a kind of disease that seriously endangers the health of pregnant women and fetuses with high incidence. This study aims to analyze the prevalence of pregnant women with hypertensive disorders complicating pregnancy and the influential factors for critical pregnant women, and to provide basis for intervention measures. METHODS: In an institution-based cross-sectional study, 100 683 pregnant women, who gave birth in all maternal and child health hospitals of Hunan Province from January 1, 2012 to December 31, 2019, were collected, and 6 579 pregnant women with hypertensive disorders complicating pregnancy were monitored. All data were analyzed through SAS9.4 software. The basic situation, clinical data, outcome, and complications of pregnant women were analyzed, and the risk factors for critical pregnant women with hypertensive disorders complicating pregnancy were analyzed. RESULTS: The prevalence rate of hypertensive disorder complicating pregnancy was increased from 4.3% in 2012 to 7.1% in 2019, and the proportion of hypertensive disorder complicating pregnant women with complications in the hypertensive disorder complicating pregnant women was increased from 28.1% in 2012 to 83.7% in 2019. Elderly pregnant women accounted for 22.2%, married women accounted for 99.9%, women with university degree accounted for 49.5%, one pregnancy accounted for 38%, and zero delivery accounted for 63.5%. In the past, 18.4% of pregnant women had more than one cesarean section, accounting for 18.4%. About 99.0% of pregnant women had 5-10 antenatal check-ups, 72.6% had complications, and 93.8% were terminated when they were discharged. The first 3 complications were anemia in 2 355 cases (29.3%), gestational diabetes in 1 886 cases (23.4%), and subclinical hypothyroidism in 947 cases (11.8%). Logistic regression analysis showed that uterine rupture, placental abruption, placenta previa, anemia, and heart disease were independent risk factors for critical pregnant women. CONCLUSIONS: The prevalence of hypertensive disorders complicating pregnancy is on the rise. Pregnancy examination should be enhanced to identify the complications such as hypothyroidism, gestational diabetes, and anemia. Prevention and treatment measures should be actively taken for uterine rupture, placental abruption, placenta previa, anemia, and heart disease.
