- The duration of the third stage of labor and prevalence of postpartum hemorrhage are increased in extremely obese pregnant women.
Why this matters
- The rates of obesity are rising worldwide.
- Obesity is associated with increased maternal and neonatal morbidity.
- Preconception counseling may help to reduce risks for maternal morbidity.
- Women with extreme obesity were more likely to deliver at an earlier gestational age (P=.0046).
- Their infants were more likely to have lower Apgar scores (P<.0001 had similar birth weights to children of normal-weight women>
- Women with BMI ≥40 kg/m2 had a longer duration of the third stage of labor compared with normal-weight women (P=.03).
- Women with BMI ≥40 kg/m2 were more likely to have a postpartum hemorrhage compared with normal-weight women (10.89% vs 3.2%; P=.01).
- Women with extreme obesity were more likely to require uterotonics at delivery (16.3% vs 8.3%; P=.04).
- Retrospective cohort study.
- Vaginal deliveries in women with BMI ≥40 kg/m2 (n=147) compared with women with BMI 2 (n=157).
- Maternal and neonatal complications were compared.
- Funding: None.
- The management of the third stage of labor was not controlled for in all deliveries.
