Utilizing the triglyceride-glucose index alongside innovative anthropometric indicators to assess mortality risk in individuals with type 2 diabetes: a prospective cohort analysis
To evaluate the association between TyG-related composite indices (TyG-BMI, TyG-WC, TyG-WWI) and all-cause mortality in elderly Chinese patients with T2DM, assess the prognostic efficacy of these composite indices, and quantify the mediating role of renal dysfunction.
Key Findings:
TyG index combined with novel anthropometric indicators demonstrated significantly improved predictive performance for mortality risk in T2DM patients.
Composite indices such as TyG-BMI, TyG-WC, and TyG-WWI were evaluated for their prognostic efficacy, revealing distinct advantages.
Renal dysfunction, indicated by eGFR, was identified as a significant mediator in the relationship between insulin resistance and mortality.
Interpretation:
The study suggests that integrating TyG with innovative obesity indices enhances mortality risk assessment in older adults with T2DM, potentially guiding targeted interventions to improve health outcomes.
Limitations:
Limited generalizability due to the study being conducted in a specific population (elderly Chinese patients), which may not reflect other demographics.
Potential biases in self-reported data regarding lifestyle factors and follow-up outcomes, which could affect the reliability of the findings.
Conclusion:
Combining the TyG index with novel anthropometric measures may provide a more accurate tool for identifying high-risk individuals with T2DM, improving health outcomes in aging populations.
