title: Obstetrical and neonatal outcomes in obese parturients.
abstract: 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.
