No age- and gender-adjusted criteria remain to be a main problem the investigators face when studying insulin resistance in children. This paper compares insulin resistance (IR) indices in 63 children and adolescents with simple (constitutionally exogenous) obesity. The authors demonstrated a low reproducibility of individual baseline values of insulin (not more than 26% as shown by Pearsons correlation analysis). Estimation of IR by means of the design indices calculated from the fasting concentration of immunoreactive insulin and glucose: 40% of obese children and adolescents had no fit of baseline IR indices with the results of an oral glucose tolerance test (OGTT), which may result in a diagnostic error - both hyperdiagnosis (in 12% of patients) and hypodiagnosis (18% of children). According to the results of this study, the values of stimulated insulin release and the Matsuda index, which were determined from the OGTT data, are of the highest diagnostic value in the assessment of insulin resistance in obesity in children and adolescents.
