Adverse maternal and neonatal outcomes in women with preeclampsia in Iran

Preeclampsia is relatively a common complication in pregnancy and is characterized by high blood pressure and protein in urine during pregnancy. Consistent with the adverse outcomes followed by preeclampsia, this study designed to investigate the how preeclampsia is associated with preterm, low birth weight (LBW), cesarean section, and weigh gain during pregnancy.

In this population-based cross-sectional study, 5166 deliveries from 103 hospitals in Tehran (Capital of Iran) were included in the analysis in 2015. The independent variable was preeclampsia during pregnancy and weight gain during pregnancy, preterm birth, cesarean section, and LBW were considered as interested outcomes. The data were analyzed by statistical Stata software (version 13, Stata Inc., College Station, TX).

Adjusted results showed that the mean of weight gain in women with preeclampsia was significantly higher than women without preeclampsia (mean difference: 1.77 kg, 95%CI: 0.76-12.78, p = .001). The adjusted odds ratio for preterm birth, cesarean section, and LBW were 4.19 (95%CI: 2.71-6.48, p = .001), 1.92 (95%CI: 1.24-2.98, p = .003), and 1.19 (95%CI: 0.61-2.31, p = .599), respectively.

Weight gain in women with preeclampsia was higher than women without preeclampsia and also the odds of preterm birth, cesarean section and LBW in women with preeclampsia was higher than women without preeclampsia.
