In 2008, an estimated 300 million women worldwide were obese (body-mass index [BMI; the weight in kilograms divided by the square of the height in meters], ≥30). 1 In 2011–2012 in the United States, 36% of adult women were obese, 2 and the majority of women in early pregnancy were either overweight or obese (BMI, ≥25). 3 Maternal obesity is a risk factor for gestational diabetes, with attendant increased risks of macrosomia, delivery complications, obesity in the offspring, and later development of type 2 diabetes in the mother. 4 – 6 Maternal obesity is also associated with an increased risk of stillbirth, 7 preterm birth, 8 and . . .
