Introduction: The visceral adiposity is a cardiometabolic risk factor, which is associate to glucose metabolism alterations. On the other hand, the non alcoholic fatty liver disease (NAFLD) appears in alarming numbers and in increase in the general population, being associated with resistance with the insulin, dislipidemy, diabetes mellitus and hypertension. They exist a variety of methods for the study of the distribution of corporal fat and the ultrasound evaluation is not an invasive method with high sensibility and specificity still in patients with normal anthropometrics measures. AIMS: To evaluate the association between the visceral adiposity and the insulin resistance in patients with increase of aminotransferases and NAFLD suspected by ultrasound in comparison with the measure of abdominal circumference. Materials and Methods: 84 patients were evaluated by increase of the values of aminotransferases and by ultrasound suspicion of NAFLD (not related to use of medicines, infectious processes and consumption of alcohol). It foresaw informed assent and application of the criteria of incorporation and exclusion, they there was realized seric analytica (including determination of HOMA's index for resistance to the insulin), evaluation of abdominal circumference, index of corporal mass and determination of visceral fat for ultrasound. Results: of 84 patients, 69 were presenting HOMA's index with diagnosis for resistance to the insulin. Of the total of 84 patients, 74 were presenting visceral adiposity increased by ultrasound whereas 10 patients were not presenting it. In turn, only 50 patients (59.52%) were presenting increase of abdominal circumference. Of the group of patients with resistance to the insulin, 100% was presenting visceral increased adiposity and 66,95% was presenting abdominal circumference increased with statistically significant difference between both groups (p <0.05). Conclusions: there is demonstrated that the visceral adiposity measured by ultrasound has a major association with resistance to the insulin that the measure of abdominal circumference in patients with not diabetic NAFLD.
