Link between diet soft drink and preterm delivery

Could drinking one or more artificially sweetened, carbonated diet sodas a day boost a woman's odds of premature delivery? A new study from Denmark suggests such a link.dblclick('xxlA');

The researchers looked at the soft drink habits of nearly 60,000 Danish women enrolled in a national study there from 1996 to 2002. The investigators found a link between the intake of diet carbonated drinks and, to a lesser extent, diet noncarbonated drinks and delivering a baby early.

The study is published online and in the September print issue of the American Journal of Clinical Nutrition. In the report, the researchers conclude: “Daily intake of artificially sweetened soft drinks may increase the risk of preterm delivery.”

The researchers defined preterm as delivering before 37 weeks' gestation. They categorized the women into groups depending on beverage drinking habits: those who never drank soft drinks or those who drank less than one per week, one to six per week, one each day, two or three per day, or four or more daily. In all, 4.6 percent of the women delivered early, and one-third of those deliveries were medically induced. The team found no association between the premature delivery and the intake of carbonated drinks sweetened with sugar.

However, compared with those who never drank the beverages, women who downed four or more diet (artificially sweetened) carbonated drinks a day were 78 percent more likely to deliver early than women who never drank the beverages. And those who had four or more diet, noncarbonated drinks daily were 29 percent more likely to deliver early. Those who had one or more carbonated diet drinks a day were 38 percent more likely to deliver early.

Why the diet drinks, especially, were linked with early delivery is not known, but the researchers speculate that the link may be driven by high blood pressure disorders in pregnancy. They note that other studies have found a link between soft drinks and high blood pressure in non-pregnant women.

Say No to Diet Soft Drinks

In previous research, scientists using information collected from the National Health and Nutrition Examination Survey (NHANES), a long-term collection of studies designed to assess the health and nutritional status of adults and children in the US, had found a link between sugar containing sodas and urinary protein. However, they did not collect data on any kidney function changes related to drinking sweetened sodas. So, in their second study, Dr. Lin and Dr. Curhan, decided to specifically check for any kidney function decline in women who drink sodas regularly. Once again, they used data from the Nurses' Health Study.

In a statement for the media, Dr. Lin reported they found “a significant two-fold increased odds, between two or more servings per day of artificially sweetened soda and faster kidney function decline; no relation between sugar-sweetened beverages and kidney function decline was noted.” Moreover, this association persisted even when the researchers accounted for age, obesity, high blood pressure, cardiovascular disease, physical activity, calorie intake, diabetes and cigarette smoking. Clearly, artificially sweetened sodas are detrimental to kidney health.

“There are currently limited data on the role of diet in kidney disease,” said Dr. Lin in a statement to the press. “While more study is needed, our research suggests that higher sodium and artificially sweetened soda intake are associated with greater rate of decline in kidney function.”
