Dr. Dora Romaguera of Imperial College London and researchers from the InterAct consortium analyzed the consumption of juices, sugar-sweetened soft drinks and artificially sweetened soft drinks collected in the European Prospective Investigation into Cancer and Nutrition.
The study, published in the journal Diabetologia, found roughly one can of a sugary drink drunk per day increased the risk of type 2 diabetes by 22 percent.
This increase in risk fell slightly to 18 percent after accounting for total calorie intake and body-mass index suggesting the effect of sugar-sweetened soft drinks on diabetes is not purely linked to body weight, Romaguera said.
People who drank more artificially-sweetened soft drinks were also more likely to get type 2 diabetes, but this association appeared to be because participants with a higher BMI tend to drink more artificially sweetened drinks and are also more likely to develop diabetes, the study said.
However, drinking pure fruit juice or diluted juices, sometimes with additives was not associated with diabetes risk, the study said.
"The increase in risk of type 2 diabetes among sugar-sweetened soft drink consumers in Europe is similar to that found in studies in North America," Romaguera said in a statement.
