Risk factors for preeclampsia: a case-control study

Objective: To explore the risk factors of preeclampsia and provide information for prevention of preeclampsia among obstetrical patients. Methods: A case-control study was designed to find the risk factors of preeclampsia among obstetrical patients by logistic regression analysis. Results: The risk factors for pregnant women were older gestational age, increasing body mass index, living in the countryside or small towns, fewer antenatal visits, and cold seasons. Conclusions: Health education should be emphasized to encourage women to have children at a relatively younger age and control weight during pregnancy. Special measures should be taken to improve the living condition and prenatal care in the countryside and small towns.
