Objective — to determine risk factors for preeclampsia in patients with severe preeclampsia and in those with eclampsia. Subject and methods. Examinations were made in 97 pregnant women (77 pregnant women, including 73 with severe preeclampsia at 20—40 weeks’ gestation and 4 with eclampsia, who made up a study group (Group 1) and 20 apparently healthy pregnant women who had no symptoms of preeclampsia and were a control group (Group 2)). Discriminant analysis, one of the statistical analysis methods, was used to clarify the most important clinical and anamnestic risk factors for preeclampsia. Results. The statistical analysis, the discriminant method, made it possible to build a model that could predict the development of preeclampsia in 93% of the examined pregnant women with preeclampsia and to calculate standardized coefficients of risk factors for this condition. The statistical analysis revealed that the most significant risk factors for preeclampsia are a history of acute metroendometritis before pregnancy; chronic hypertension found in maternal first-degree relatives; diabetes mellitus detected in maternal relatives; kidney diseases; baseline hypertension; diabetes mellitus in paternal first-degree relatives; chronic hypertension in paternal relatives; and vascular diseases in a pregnant woman. Conclusion. The study allows one to make up a group of pregnant women at high risk for severe preeclampsia during pregravid preparation in the first and second trimesters of pregnancy. The authors declare no conflicts of interest.
