Purpose
Although Triglyceride glucose-waist-to-height ratio (TyG-WHtR) is an indicator for insulin resistance, the relationship between TyG-WHtR and newly diagnosed diabetes is unclear. The intention of this research is to examine the causative association between TyG-WHtR and new-onset diabetes.
Methods
We conducted a retrospective 10-year cohort study of 10150 Chinese adults. After screening out the unqualified people, the TyG-WHtR level of 8279 participants was calculated in this study, and a multivariate logistic regression model was used to investigate the possibility that it has a connection with diabetes.
Results
Within 10 years, 271 men (3.27%) and 532 women (6.43%) were newly diagnosed with diabetes. Multivariate Cox regression analysis reveals a linear relationship between TyG-WHtR index and newly diagnosed diabetes mellitus (HR=8.889, 95% CI: 4.703 to 16.801, P < 0.001), and TyG-WHtR shows great AUC (0.750, 95% CI: 0.733-0.767). Addionally, TyG-WHtR associated diabetes was shown to be substantially more prevalent in people aged 71 to 80, with a BMI below 24 kg/m2 and no hypertensive condition (P < 0.05), according to subgroup analysis.
Conclusion
According to the study, TyG-WHtR might be an accuracy indicator of future diabetes risk and outperform other commonly used anthropometric indices.
