OBJECTIVES: Our aim was to investigate the association between the triglycerides/glucose index (TyG index) and the homeostasis model assessment-estimated insulin resistance (HOMA-IR) in the prediction of insulin resistance (IR) among adolescents.METHODS: We conducted a cross-sectional study among 221 Korean adolescents (168 males and 53 females aged 9-13 years) from May to June 2014 in Chung-ju city. The TyG index was calculated as ln [triglycerides (mg dl(-1)) x fasting glucose (mg dl(-1))/ 2]. IR was defined using HOMA-IR 495th percentile for age and sex.RESULTS: In the IR group, weight, body mass index (BMI), waist circumference, body fat, fasting insulin, fasting plasma glucose, triglyceride levels and triglycerides/high-density lipoprotein cholesterol (TG/HDL-C) were significantly higher than that in the non-IR group. The TG index was significantly different between the IR group (n = 22) and non-IR group (n = 199), at 8.43 +/- 0.45 and 8.05 +/- 0.41, respectively (P < 0.001). The TyG index was well correlated with HOMA-IR (r = 0.41; P < 0.001) and showed a strong positive association with TG/HDL-C (r = 0.84; P < 0.001). The cut-off of the TyG index for diagnosis of insulin resistance was 8.18.CONCLUSIONS: The TyG index is a simple, cost-effective surrogate marker of insulin resistance among adolescents compared with HOMA-IR.
