Association between CVAI-defined body composition phenotypes and prediabetes outcomes in Chinese adults undergoing health check-ups: a cross-sectional study (opens in new tab)

BackgroundPrediabetes presents a critical opportunity to prevent type 2 diabetes and its complications. Both visceral adiposity and low skeletal muscle mass are closely linked to insulin resistance; however, it remains unclear whether body composition phenotypes—defined by relative muscle mass and the Chinese visceral adiposity index (CVAI), which is a validated measure of visceral fat accumulation in Chinese adults—are differentially associated with specific prediabetes outcomes. Therefore, ...
