RESUMO
Six normal, 6 obese and 12 hyperandrogenic women of similar ages, were studied. In two consecutive days, the ITT and the IVGTT were performed and a basal blood sample was obtained to measure SHBG, DHEAS and IGFBP-1. Insulin sensitivity was calculated as the blood glucose slope in the ITT and with the minimal model of Bergman in the IVGTT. Insulin sensitivity, measure with ITT was 0.58 (0.53-0.63) in normal, 0.38(0.05-0.59) in obese and 0.20(0.0-0.36) in hyperandrogenic women. The figures for the IVGTT were 7.97(4.1-15.4), 2.41 )0.81-4.89) and 1.1 (0.46-1.88), respectively. Both methods had a positive correlation coefficient of 0.792 (p 0.09). IGFBP-1 values were 3.0, 2.1 and 1.6 ng/ml respectively (p 0.05). DHEAS values were 132, 190 and 206 ug/dl, respectively (ND). ITT is a sample and reliable method to asses insulin sensitivity. SHBG discriminates subjects with different levels of insulin sensitivity
