Study Links Sugary Drinks During Pregnancy to Childhood Obesity

ELK GROVE VILLAGE, Ill. — School-age children whose mothers consumed more sugary beverages in mid-pregnancy had higher amounts of body fat than those whose mothers drank fewer sweetened beverages, according to a study published in the August 2017 issue of Pediatrics.

The study, “Beverage Intake During Pregnancy and Childhood Adiposity,” looked at 1,078 mother-child pairs in a pre-birth cohort study in Massachusetts. Researchers measured the mothers’ intake of sugary and non-sugary beverages during their first and second trimesters of pregnancy between 1999 and 2002. They found an association between mothers who drank more sugary beverages during their second trimester and their children’s excess weight by mid-childhood, at a median age of 7.7 years.

Among 8-year-old boys and girls of average height who consumed at least a half-serving a week of sugary beverages, their weights were approximately 1 kg higher if their mothers had consumed at least two servings a day of sugary beverages while pregnant. Maternal intake of the sugary beverages — rather than the child’s diet — was more strongly related to the child’s susceptibility to gaining excess weight. Avoiding high intake of sugary beverages during pregnancy could be one of several ways to prevent childhood obesity.
