A plateau in new onset type 1 diabetes: Incidence of pediatric diabetes in the United States Military Health System.

Objectives: To describe the incidence and prevalence of type 1 diabetes among pediatric dependents of the US Department of Defense. Methods: The Military Health System (MHS) data repository was used to identify pediatric patients (≤17 years of age) with type 1 diabetes from January 1, 2007 to December 31, 2012. Annual incidence, annual prevalence and adjusted incidence were calculated and stratified by sex, age group, and region of residence. Results: Within a 6‐year study period from 2007 to 2012, 5616 pediatric patients with type 1 diabetes were identified; 57% male, mean (SD) age of 10.9 (4.2) years. Annual type 1 diabetes incidence (per 100 000 persons) over the 5‐year time period ranged from 20.7/100 000 to 21.3/100 000. Incidence for each year was highest in the 10 to 14 years age group and ranged from 30.9/100 000 in 2008 to 35.2/100 000 in 2011. Annual type 1 diabetes prevalence (per 1000 persons) remained stable throughout the study period at 1.5/1000. Adjusted incidence for males was significantly higher compared to females (21.0/100 000 vs 18.1/100 000; P = .001). During the study period, annual incidence remained steady (test for trend, P = .984). Conclusions: The incidence of type 1 diabetes among children appears to plateau during the study period, suggesting a steady state of type 1 diabetes within this pediatric population. The MHS provides an accurate and up to date look at incidence of type 1 diabetes and may reflect broader trends of incidence of pediatric disease for the United States as a whole.
