Usefulness of the Triglyceride Glucose Index to Predict Nonalcoholic Fatty Liver Disease in Children with Obesity

Song et al 1 reported the usefulness of triglyceride glucose (TyG) index and modified TyG indices in predicting nonalcoholic fatty liver disease (NAFLD) in general Korean youths aged 10-19 years. The TyG index, calculated from fasting glucose and triglyceride levels, has high sensitivity and specificity for identifying insulin resistance. 2 This study found the TyG index and modified TyG indices significantly predicted pediatric NAFLD. Area under the receiver operating characteristic (AUROC) values for NAFLD detection ranged from 0.667 to 0.780 as follows: TyG, 0.667; TyG-BMI, 0.774; TyG-BMI SDS, 0.774; TyG-waist circumference (WC), 0.776; and TyG-waist-to-height ratio (WHtR), 0.780.
