Pregnant women who drink artificially sweetened drinks every day may be more likely to give birth to heavier babies who are then more likely to become overweight children, researchers report.
“Infants born to women who regularly consumed one or more artificially sweetened beverages during pregnancy were twice as likely to be overweight by 1 year of age,” said study author Meghan Azad, a research scientist at the University of Manitoba in Winnipeg, Canada.
By her definition, an overweight baby weighs more than 97 percent of other babies of the same height and weight.
This is the first study to investigate the potential effect of consuming artificial sweeteners during pregnancy and infant weight gain, Azad said. Interestingly, the researchers did not find any connection between drinking sugar-sweetened drinks and infant weight.
And the effects were not explained by maternal weight, diet, total calories consumed or other obesity risk factors, she added.
Although the study didn’t prove that artificially sweetened drinks cause infant weight gain, “caution is warranted,” Azad said.
“Given the current epidemic of childhood obesity and widespread use of artificial sweeteners, further research is warranted to confirm our findings and investigate the underlying biological mechanisms. Ultimately, this research could help improve dietary recommendations for pregnant women,” Azad said.
For the study, Azad and her colleagues collected data on more than 3,000 mothers and their babies. The women were asked what drinks they consumed during pregnancy. Nearly 30 percent said they drank artificially sweetened beverages, including 5 percent who reported drinking them on a daily basis.
The consumption of artificially sweetened drinks was determined by how often women drank soda or iced tea containing artificial sweeteners or added sweeteners to coffee or tea, Azad explained. The researchers could not determine which artificial sweeteners were consumed in each case.
The study findings were published online May 9 in the journal JAMA Pediatrics.
