- The triglyceride glucose index-a body shape index (TyG-ABSI) is a novel metric combining lipid metabolism and body morphology to predict cardiovascular disease (CVD) risk.
- In a Chinese cohort study from CHARLS (2011-2020), TyG-ABSI was independently associated with increased risks of composite CVD and stroke, but not heart conditions alone.
- While TyG-ABSI improved prediction over ABSI, it did not outperform traditional indices like TyG-BMI in overall accuracy or net benefit, as shown by decision curve analysis.
- TyG-ABSI showed negligible correlation with BMI, indicating it captures unique body shape-related risks, unlike traditional indices that exhibited severe multicollinearity.
- Future risk stratification may benefit from integrating TyG-BMI's metabolic sensitivity with TyG-ABSI's specific body shape insights in an Anthropometric Risk Indicator (ARI) framework.
