Objective: To determine in multivariate analysis the clinical, social, and demographic factors for preeclampsia.
Study design: A case-control study was designed. Three hundred patients were included, divided in two groups. 150 cases with criteria diagnosis for preeclampsia. 150 patients with normal pregnancy and deliveries. The main variables analyzed were age, schooling, marital status, employment, socioeconomic status, smoking and alcohol consumption, body mass index, familiar history of preeclampsia, history of preeclampsia in previous pregnancy, parity and type of pregnancy (single or multiple).
Statistical analysis: For comparison of cases and controls on categorical variables, odds ratios and 95% confidence intervals were calculated, and multiple logistic regression analyses.
Results: Multiple logistic regression analysis showed that history of preeclampsia in previous pregnancy has OR 23.7, 95% p < 0.001, familiar history of preeclampsia OR 1.62, p < 0.08, high body mass has OR 1.60.
Conclusions: The knowledge of the most important risk factors in our population could be useful for the clinical to pre-detect the patient who will develop preeclampsia.
