The knowledge of this parameter characterizing individual patients may be of great value not only for better understanding of the disease course but also as a potential source of specific treatment. Reliable estimation of insulin resistance with hyperinsulinemic euglycemic clamp is a complex, laborious and costly procedure. These facts were enough to motivate us to make an attempt to elaborate an indirect, simplified method of insulin resistance assessment in T1DM children, that would be based on patients characteristics and on clinical parameters of the disease course.</p><p><strong>Materials and methods: </strong>142 children and adolescents with T1DM (79 boys, 63 girls) aged 7.7-20.3 years (mean age - 13.7+/-3.3 years) were included into the study. Duration of diabetes was 0.5-12.5 years (mean 2.7+/-2.3 years). The stage of puberty was assessed by the Tanner scale. Euglycemic-hyperinsulinemic clamp by de Fronzo was performed to estimate insulin resistance. Glucose disposal rate (M index) determined during the last 30 min of the test estimated insulin resistance. Looking for clinical and metabolic factors characterizing insulin resistance: a) the plasma cholesterol, HDL-Ch, triglycerides and HbA1c were examined, b) the height, weight, waist circumference and blood pressure were measured, c) body mass index and daily dose of insulin were calculated. For statistical analysis the multiple regression was used (forward stepwise method).</p><p><strong>Results: </strong>In the study group M index ranged from 2.1 to 17.4 mg/kg/min (mean 7.27+/-2.62 mg/kg/min).

A correlation between M index and insulin dose (r=-0.34, p<0.05) and HbA1c (r=-0.17; p=0.04) were found.
