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.
