Obesity during pregnancy may lead directly to fetal overgrowth, NIH study suggests

Obesity during pregnancy — independent of its health consequences such as diabetes — may account for the higher risk of giving birth to an atypically large infant, according to researchers at the National Institutes of Health. Their study appears in JAMA Pediatrics.

“Our results underscore the importance of attaining a healthy body weight before pregnancy,” said the study’s lead author, Cuilin Zhang, M.D., Ph.D., a researcher in the Division of Intramural Population Health Research at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development. “They also suggest that clinicians should carefully monitor the pregnancies of all obese women, regardless of whether or not they have obesity-related health conditions.”
