MedWire (2/9, Grice) reported, “Recent NHANES data estimate the prevalence of prediabetes to be about 16 percent in 12 to 19-year old US youths.” Chaoyang Li, of the CDC, and colleagues, “analyzed data from participants aged 12–19 years in the 2005–2006 National Health and Nutrition Examination Survey,” and found that "the unadjusted prevalences of [impaired fasting glucose (IFG)], [impaired glucose tolerance (IGT)], and prediabetes were 13.1 percent, 3.4 percent, and 16.1 percent, respectively. IFG accounted for nearly 80 percent of adolescents with prediabetes.
" Their findings, “reported in the journal Diabetes Care, show that the prevalence of prediabetes was 2.4-fold higher in boys than girls, 2.6-fold higher in overweight adolescents than those with normal weight, and four-fold higher in adolescents with hyperinsulinemia than those without.”
