Parental Income Level and Risk of Developing Type 2 Diabetes in Youth
Authors' conclusion
This population-based cohort study showed that children and adolescents from very-low-income to middle-income families had a higher hazard of youth-onset type 2 diabetes and mortality than those from high-income families. Further research to reveal the factors underlying this association may improve the accuracy of identifying individuals at greatest risk for developing type 2 diabetes in youth.
