Popis: BACKGROUND Insulin resistance has been recognized as a major factor in the development of non-alcoholic fatty liver disease (NAFLD). The association between insulin resistance and NAFLD, as a risk factor independent of obesity has been less well established. This study aims to determine presence of insulin resistance and components of metabolic syndrome in non-obese patients with NAFLD. METHODS 150 patients (mean age 42.25 _ 10.50 y; 115 (76%) male, 35 (24%) female) diagnosed with NAFLD participated in the study. We measured body mass index (BMI), waist circumference (WC), waist hip ratio (WHR), fasting lipid profile, fasting glucose, fasting insulin, and liver function. Insulin resistance was calculated using the homeostasis model of assessment (HOMA) formula. Insulin resistance was arbitrarily considered altered when it was >1.64. RESULTS 120 (80%) of the 150 patients were pbese (BMI >23) according to the Asia Pacific criteria. 40 (30%) had metabolic syndrome. 97.5% (117/120) had insulin resistance with mean HOMA-insulin resistance (IR) of 10.9+/-5.3. Thirty (20%) were non-obese; of these, 7 had central obesity (WC > 90 cm for men, > 80 cm for women). Twenty-three (15.3%) patients were lean NAFLD with BMI 21.6+/-1.5, WC 82.9+/-4.7 (BMI< 23, WC
