A pregnant woman’s high blood sugar level is linked to a significantly greater long-term risk of obesity in her child—even more than a decade later, a new study reports. The higher the woman’s blood sugar, the greater the risk of her child being obese.
“The mother’s blood sugar level during pregnancy is an independent contributor to the child’s weight and risk of being obese later in childhood,” says corresponding study author Boyd Metzger, professor emeritus of medicine in endocrinology at Northwestern University Feinberg School of Medicine.
“We’ve known for a long time that family characteristics predict a lot about how you’re going to look…,” Metzger says. “This is above and beyond the mother’s weight. This takes into account all those other factors.”
