Maternal Obesity & Cesarean Delivery Risks

Am J Obstet Gynecol; ePub 2017 Feb 13; Smid, et al

Women who are maternally obese have greater risk for post-cesarean complications compared with non-obese women; however, the risk of intraoperative complication does not appear to be increased in obese women, a recent study found. This secondary analysis included 51, 218 women who underwent cesarean delivery. Researchers found:

  • 38% of women had body mass index (BMI) of 18.5-29.9 kg/m2; 47% BMI 30-39.9 kg/m2; 12% BMI 40-49.9 kg/m2, and 3% had BMI ≥50 kg/m2.
  • In fully adjusted model 2, women with BMI 40-49.9 kg/m2 had a lower risk of any intraoperative complication compared to women with BMI 18.5-29.9 kg/m2.
  • Women with BMI 30-39.9 kg/m2 had a similar risk of any intraoperative complication compared to non-obese women.
  • There was no increased risk of intraoperative complication among super obese women compared to non-obese women.
