The influence of obesity on pregnancy outcome

In a retrospective study we analyzed the influence of obesity on pregnancy outcome. Maternal BMI (kg/m2) was calculated at the first obstetrical visit and defined as <25 kg/m2 normal BMI, overweight 25-29.9 kg/m2, and obese >30 kg/m2. Maternal outcomes included caesarean deliveries, gestational hypertension, and preeclampsia. Fetal/neonatal outcomes included newborns weight, macrosomia, major congenital malformations, stillbirth, neonatal death, and perinatal mortality. Women with normoglycemia were included. Maternal and infant outcomes correlated with BMI. A total of 1377 women fulfilled the criteria. Caesarean deliveries increased in overweight (27.8 %) and obese (30.5%). The incidence CS in women in normal BMI was 15.7%. Hypertensive disorders (gestational hypertension and preeclampsia) increased in overweight (9.2%) and in obese women (13.6%). Mean birth weight was 3268 ±760.4 g in normal BMI, 3470±715 g in overweight, and 3535±873g in obese (p < 0.05) mothers. Macrosomia occurred in 11.3%, 18.9%, and 23.5% of newborns of normal BMI, overweight, and obese mothers, respectively (p < 0.001). Congenital malformations occurred in 1.7%, 2.8% and 3.2% in normal BMI, overweight and obese women. Perinatal mortality was 0.5%, 1.2%, and 1.1% in normal BMI, overweight and obese mothers. Overweight and obese women have greater adverse pregnancy outcomes.
