A new study has found a link between antibiotic use for pregnant moms and obesity risks for their children.
For the study, researchers evaluated 436 mothers and their children from birth until age seven. Using interviews, they assessed each mother's antibiotic use while she was pregnant. After considering factors such as gestational age, birth weight, breast-feeding, maternal body mass index (BMI) and socioeconomic status, the team found that antibiotic use during the second and third trimesters was associated with an 84 percent increased risk for obesity in the child.
Previous studies have shown that when babies are given antibiotics early in life they have a greater risk for obesity later on. But this is the first time that researchers have looked at the link between maternal antibiotic use — specifically that in the second or third trimester of pregnancy — and the risk for obesity in her children.
