The prevalence of type 1 diabetes in U.S. adolescents rose by 23% between 2001 and 2009, according to University of Colorado researchers.
The journal Pediatrics just recently published an article stating that the incidence of diabetes and prediabetes in U.S. adolescents increased from 9% in 1999 to 23% in 2008. From that report, however, I couldn’t tell how much of the increase was type 1 versus type 2.
No one knows why type 1 diabetes in youths is increasing. The rise in type 2 diabetes is likely related to higher obesity rates.
