Research Article: Association between triglyceride glucose index and odds of hip fracture in patients with or without type 2 diabetes: a cross-sectional study
Abstract:
The triglyceride-glucose (TyG) index, an indicator of insulin resistance, has demonstrated variable correlations with fracture risk. This study sought to examine the correlation between TyG and the odds of hip fractures in Chinese individuals, both with and without type 2 diabetes (T2D).
This retrospective cross-sectional study was performed at Changzhou Second People’s Hospital and involved 935 Chinese individuals, including 248 patients with hip fractures. TyG was calculated based on fasting glucose and triglyceride levels. Multivariate logistic regression models were used to investigate the association between TyG and the odds of hip fracture.
The odds of hip fractures was identical in both T2D and non-T2D groups (27.5% vs 26.3%, P = 0.734). After adjusting for all confounders, increasing TyG significantly reduced the odds of hip fracture in the group without T2D (odds ratio [OR] = 0.45; 95% confidence interval [CI]:0.25–0.83), but not in the T2D group (OR = 1.90; 95% CI:0.81–4.46). A significant multiplicative interaction was observed between T2D and TyG on the odds of hip fracture (p for interaction < 0.01). In addition, there is no association between TyG and bone mineral density (BMD) in either the T2D or without T2D participants (p > 0.05).
Significant elevations in TyG were independently associated with a reduced odds of hip fractures in Chinese individuals without T2D, but not in those with T2D. These findings underscore the necessity of considering diabetes status when evaluating the TyG index as a metabolic determinant of hip fracture odds in clinical practice.
