The Triglycerides/Glucose (TyG) index is a simple, cost-effective surrogate marker of insulin resistance among adolescents compared with HOMA-IR.

The TyG index is calculated as: [triglycerides (mg dl−1) × fasting glucose (mg dl−1)/2]. IR was defined using HOMA-IR >95th percentile for age and sex. The cut-off of the TyG index for diagnosis of insulin resistance was 8.18.
