The authors of a new study slated for publication in the September issue of the American Journal of Clinical Nutrition are urging pregnant women to limit their intake of any sweetened beverage after their research found that pregnant women who drank more than one artificially or sugar-sweetened beverage per day had a small increased risk of pre-term births (before 37 weeks).
The study from researchers at the Norwegian Institute of Public Health (NIPH), Sahlgrenska University Hospital, and Sahlgrenska Academy in Gothenburg compiled data from questionnaires filled out by more than 60,000 pregnant women. The study found that preterm births were associated with a high body mass index, poor diet, lower education, daily smoking, and single women—and that all the women in these categories were more likely to drink more than one serving of sweetened beverages per day.
The study confirms the findings of an earlier Danish study which showed a link between pre-term births and artificially sweetened beverages in both normal and overweight women.
“Although the Norwegian data confirmed the Danish findings regarding an association between artificially sweetened drinks and preterm delivery, we cannot at present…claim artificial sweeteners have a causal relationship to preterm birth,” the researchers wrote.
The beverage industry has lashed out at the report, calling it “bad science” and “data trawling” that was scaring people unnecessarily.
