Abstract
OBJECTIVE: Several studies have shown that obese children and adolescence seem to have an increased risk to develop a disturbed glucose metabolism as already known for obese adults. This might result in the same disastrous outcomes of cardiovascular diseases as it has been shown for adult obese patients. The most sensitive measurement for detecting changes in glucose metabolism in obese children seems to be an oral glucose tolerance test (OGGT) which is not practical for all daily outpatient clinics. DESIGN: Cross-sectional study. SUBJECTS AND MEASUREMENTS: We therefore made a preselection from a cohort of 491 subjects according to the American Diabetes Association (ADA) criteria for the diagnosis of diabetes. In the selected high-risk subgroup (n = 102) of obese pediatric subjects, we measured the prevalence of impaired glucose tolerance (IGT) by OGTT. RESULTS: We diagnosed six patients with type 2 diabetes and 37 patients with impaired glucose tolerance. In addition, we found a close correlation of IGT to disturbances of triglyceride and cholesterol parameters. This prevalence was comparable to a similar study group that was screened without preselection. CONCLUSIONS: These prevalence data further underline the need to diagnose children with obesity-associated risk factors in terms of an insulin resistance syndrome. The preselection of a high-risk subgroup by ADA criteria might be a practical approach.
