Section snippets
Methods
The SEARCH for Diabetes in Youth Study is ongoing at 6 study centers in the United States, with the goal of describing the epidemiology of childhood diabetes according to race/ethnicity, age, sex, and diabetes type. The study design has been published previously.9 It involves identifying existing (prevalent) cases of nongestational diabetes in patients under age 20 years in 2001 and newly diagnosed (incident) cases in subsequent calendar years, with the goal of complete case ascertainment in
Results
The overall mean HbA1c value was 8.18% ± 1.59% for youth with T1D and 7.99% ± 2.51% for youth with T2D. Overall, 17% of the youth with T1D and 27% of those with T2D had poor glycemic control (ie, HbA1c ≥ 9.5%) (Table I; available at www.jpeds.com). For both T1D and T2D, the percentage of youth above the age-specific target HbA1c was higher with increasing age at the time of the SEARCH examination. In those age 19+ years, 29% of those with T1D and 47% of those with T2D exhibited poor glycemic
Discussion
A high proportion of children and youth with diabetes in this study exhibited poor HbA1c values. This finding is particularly disturbing given that almost all of the youth were insured and all were motivated to volunteer for research.
Our finding of poor glycemic control in youth with T1D is similar to published data from other countries.8, 16 In these countries, there were center variations in glycemic control that were not explained by demographic or clinical factors. It has been suggested
