Prevalence of Diabetes Increasing in U.S. Youth
(HealthDay News) — From 2001–2009, the prevalence of type 1 and type 2 diabetes increased among youth in the United States, according to a study published in the May 7 issue of the Journal of the American Medical Association, a theme issue on child health. This issue was released early to coincide with the annual meeting of the Pediatric Academic Societies, held from May 3–6 in Vancouver, Canada.
Dana Dabelea, MD, PhD, from the Colorado School of Public Health in Aurora, and colleagues estimated changes in the prevalence of type 1 and type 2 diabetes in U.S. youth between 2001–2009.
The researchers found that the prevalence of type 1 diabetes increased from 1.48 per 1,000 in 2011 to 1.93 per 1,000 in 2009. The prevalence was highest among white youth (2.55 per 1,000) and lowest in American-Indian youth (0.35 per 1,000). Over eight years there was a 21.1% increase in type 1 diabetes after adjustment for completeness of ascertainment. For type 2 diabetes, the prevalence increased from 0.34 per 1,000 in 2001 to 0.46 per 1,000 in 2009. The prevalence was highest among American-Indian youth (1.20 per 1,000) and lowest among white youth (0.17 per 1,000). Over eight years there was a 30.5% increase in type 2 diabetes after adjustment for completeness of ascertainment.
"Further studies are required to determine the causes of these increases," the authors write.
