Hypothesis
What is the association between surrogates for insulin resistance and mortality in primary care patients?
Conclusion
Both low and high levels of TyG-BMI and TyG-WC are associated with increased mortality and reduced life expectancy.
Supporting Evidence
- Cumulative total and premature all-cause mortality were 7.2% and 4.6%, respectively.
- Lowest and highest quartiles of TyG-BMI and TyG-WC were associated with increased mortality.
- Patients in the lowest and highest quartiles experienced a reduction in life expectancy.
Takeaway
This study found that both too low and too high levels of certain body measurements related to insulin resistance can lead to a higher chance of dying earlier.
Methodology
The study analyzed data from a nationwide cohort of patients aged 45 and older, assessing the relationship between TyG-related indicators and mortality over a follow-up period of approximately 5.7 years.
Potential Biases
Potential residual confounding due to unmeasured variables.
Limitations
The study is observational and may not establish causality; it also did not account for all potential confounders.
Participant Demographics
Mean age 61.8 years; 63.5% female.
