Association of the Triglyceride-Glucose Index with Visceral Adiposity and Insulin Resistance in Young Individuals

Background: Type 2 diabetes mellitus (T2DM) is a major global health concern, with insulin resistance (IR) playing a critical role in its development, along with cardiovascular diseases and metabolic syndrome. The triglyceride-glucose (TyG) index has emerged as a reliable and cost-effective alternative to traditional IR assessment methods, such as homeostatic model assessment for IR (HOMA-IR). In addition, visceral adiposity is strongly associated with IR and metabolic dysfunction, yet the relationship between the TyG index and visceral adiposity markers remains underexplored. This study aimed to evaluate the association between the TyG index, visceral adiposity index (VAI), and IR in a young population.
