OBJECTIVE: Obstetrical risk is increased with maternal obesity. This prospective study was designed to simultaneously evaluate the outcomes in obese parturients and their newborns. METHODS: Patients with a body mass index (BMI) > or =35 were prospectively identified and compared to an equal number of normal weight parturients. Maternal and neonatal outcome measures were compared for the peripartum and neonatal period. RESULTS: We identified 580 obese parturients over a 6 month period and compared them to an equal number of normal weight parturients. The incidence of obesity in this population was 23%. Obesity was associated with increased rates of hypertension, diabetes, and cesarean section. Obese patients were more likely to develop postpartum complications. Neonatal outcomes were compared for infants > or =37 weeks gestation excluding multiple births (496 neonates in the obese group and 520 in the control group). The neonates of obese parturients were more likely to be macrosomic, have 1-minute Apgar scores of < or =7.0 and require admission to a special care unit. Sub-group analysis showed that negative outcomes for parturients and their neonates correlated with increasing BMI. Neonates born to obese diabetic parturients had the highest risk of poor outcomes. CONCLUSIONS: Maternal obesity confers increased risks for both the parturient and their newborn.
