- Super obese women (BMI >50 kg/m2) are at risk for maternal and neonatal pregnancy complications.
Why this matters
- Rates of obesity are increasing worldwide.
- Preconception counseling to achieve lower BMI may help reduce pregnancy complications.
- Increased antepartum surveillance is important for super obese pregnant women.
- No maternal deaths noted.
- Compared with women without super obesity, thrombotic event odds were higher among super obese women (OR, 9.39; 95% CI, 1.15-76.43).
- Women with BMI >50 kg/m2 had increased risk for (aORs, using model 3 for adjustment):
- Preeclampsia: 4.81 (P<.001>
- Cesarean delivery: 3.07 (P<.001>
- Induction of labor: 2.48 (P<.001>
- Cesarian delivery wound infection: 7.25 (P<.001>
- Macrosomia: 8.05 (P<.001 and>
- 5-minute Apgar
