The incidence of preeclampsia study 7.8 percent. Mean weight gain during pregnancy, preeclampsia in 13.5 ± 5.21kg. The highest percentage of subjects with preeclampsia, body mass index 29 or more in the first trimester had. Risk of giving preeclampsia in women with a high body mass index(BMI 26 or more) was 2.19 times more than women with normal body mass index (OR = 2.19, 95%CI = 0.97-4.9). The findings of this study show that there are significant differences between maternal body mass index in the first trimester of pregnancy and preeclampsia (p=0.008). Conclusion: It seems that maternal body mass index during first trimester of pregnancy and excessive weight gain in pregnancy can be a predictive factor for developing preeclampsia and its helpful in recognizing mothers at risk of preeclampsia.
