Objective: To evaluate the effects of class III obesity in pregnancy on maternal and perinatal outcomes.
Design: Retrospective 12 month cohort study using the Hawkes Bay DHB maternity database to assess obstetric outcomes in obese women compared to their normal BMI counterparts.
Method: Women with singleton pregnancies and recorded height and weight were included. Maternal outcomes of interest included gestational hypertension, gestational diabetes, mode of delivery, induction of labour, post-partum haemorrhage, wound infection. Perinatal outcomes included preterm birth, small for gestational age or large for gestational age , SCBU admissions, mechanical ventilation at birth.
Results: 162 women were included in the study; 81 women in the obese group and 81 women in the normal BMI group for data comparison. Maternal obesity was associated with increased hypertension, gestation diabetes, pre-term deliveries, small for gestational age babies, large for gestational age (RR 7.17, P<0.05), admission to SCBU and need for mechanical ventilation. It was less likely for women in the obese group to spontaneously labour compared to normal BMI group (RR 0.32, P<0.05). Obese women were more likely to have a caesarean section and less likely to have vaginal deliveries compared to women of normal BMI (RR 2.4 vs 0.4, P<0.05).
Conclusions: Maternal obesity contributes significantly to obstetric complications, particularly in the intrapartum period. Encouraging healthier BMI pre-conceptually and effective risk management antenatally could significantly improve pregnancy outcomes.
