Session: S02-Endocrine Controversies in Pregnancy
Room 104 (Moscone Center)
Eating for two may no longer be such a good idea. Although maternal obesity and excessive gestational weight gain (GWG) are recognized risk factors for childhood obesity, unabated controversy persists over the ideal weight gain during pregnancy. The strongest predictor of postpartum weight retention is GWG yet more than 50% of women gain weight above the Institute of Medicine (IOM) guidelines and pregnant women often receive contradictory advice. Surprisingly, the 2009 IOM guidelines differ little from the 1990 guidelines yet recent data suggest that women with more severe obesity might benefit from less weight gain. Although weight reduction before pregnancy is the ideal goal, it is often unattainable. A more constrained GWG recommendation or modest weight loss might have a positive impact for high BMI women. This symposium will review the substantial health risks of obesity during pregnancy and the data supporting lower GWG targets to benefit pregnancy outcomes as well as the long-term health of both mother and infant.
