The prevalence of both type 1 and type 2 diabetes in US children and adolescents increased significantly from 2001 through 2009, according to the results of a large study published in the May 7, 2014, issue of the Journal of the American Medical Association
The study estimated changes in the prevalence of type 1 and type 2 diabetes among more than 3 million children younger than 20 years. From 2001 to 2008, the prevalence of type 1 diabetes, after adjustment, increased 21.1%. The prevalence of type 2 diabetes also increased among multiple subgroups during the study period. After adjustment, the proportion of children diagnosed with type 2 diabetes increased 30.5%. Increases in the prevalence of type 1 diabetes are most likely due to rising disease incidence, the authors note, while increases in type 2 diabetes prevalence may be due to changes in population risk, such as minority population growth, obesity, and exposure to diabetes in utero.
