Objectives. the present study aimed at determining cut-off points of visceral fat to predict nafld and analyzed metabolic disorders of obese adolescents. methods. cross-sectional study involved 165 obese adolescents ranged in age from 15 to 19 years. glycemia,hepatic transaminases,lipid profile,and insulin resistance were analyzed. visceral and subcutaneous fat were measured by ultrasound and body composition by plesthysmography. results. the nafld adolescents had significantly higher values for body mass,bmi-for-age,bmi,total fat,waist circumference,and visceral fat when compared with non-nafld obese adolescents in both genders. moreover,there were significant positive correlations between visceral fat with the variables bmi-for-age (r = 0.325,),tg (r = 0.277),ast (r = 0.509),alt (r = 0.519),wc (r = 0.390),and visceral/subcutaneous ratio (r = 0.790) for nafld group. total fat,triglycerides,and visceral fat were the independent predictors to nafld. analysis of the roc curves revealed cut-off points of visceral fat of 4.47 cm for girls and 4.21 cm for boys. conclusions. the results may suggest that abdominal ultrasonography procedure may be a safe alternative method of assessing visceral adiposity aiming to be considered to the development of preventive and treatment strategies in obese individuals. this clinial trial is registered with clinicaltrial.gov (nct01358773). © 2013 ana paula grotti clemente et al.
