Poor diet associated with increased diabetes risk across all
Both genetic and lifestyle factors are known to contribute to individual susceptibility to type 2 diabetes. In the new study, researchers analyzed data from three extensive cohort studies, including 35,759 U.S. health professionals followed for 902,386 person-years of follow-up.
The team found that, irrespective of genetic risk, a low diet quality, as compared to high diet quality, was associated with a 30% increased risk of type 2 diabetes (Pinteracti The relative risk of type 2 diabetes was 1.29 (95% CI 1.25-1.32, P<0.001) per standard deviation increase in the global polygenic score -- one measure of genetic risk -- and was 1.13 (1.09-1.17, P<0.001) per 10-unit decrease in Alternate Healthy Eating Index, a measure of diet quality. The joint association of low diet quality and increased genetic risk was similar to the sum of the risk for each factor alone (Pinteracti further supporting independent associations.
