Pregnancy: Shed Pounds for Successful VBAC

NEW ORLEANS — Overweight and obese women can improve their chance of having a successful vaginal birth after cesarean delivery (VBAC) by losing weight between pregnancies, a researcher reported here.

In a population-based, retrospective cohort study, overweight women who lost at least 1 BMI unit between pregnancies were 12% more likely to have a successful VBAC, compared with overweight women who maintained their weight (aRR=1.12, 95th% CI 1.01 to 1.25), reported lead author Lisa S. Callegari, MD, MPH, of the University of Washington.

Obese women who lost 1 or more BMI units between pregnancies had a 24% greater chance of successful VBAC (aRR=1.24, 95th% CI 1.01 to 1.25), she said here during her oral presentation at the annual clinical meeting of the American Congress of Obstetricians and Gynecologists.
