Insulin resistance (IR) is closely associated with stroke risk. The triglyceride glucose-weight-adjusted waist index (TyG-WWI) is a novel biomarker for IR estimation. However, the relationship between the TyG-WWI index and stroke risk in the general population remains unexplored. This study aims to explore the potential relationship between the TyG-WWI index and stroke risk in the general population.
A total of 22,615 participants from the 1999-2018 NHANES programme were included in this study. Multivariate logistic regression models, restricted cubic spline regression, subgroup analyses and sensitivity analysis were performed to explore the relationship between the TyG-WWI index and stroke risk in the general population.
Among the 22,615 participants included in the study, 812 participants were identified as stroke patients. After adjusting for multiple confounders, multivariate logistic regression analyses indicated that each SD (standard deviation) increase in the TyG-WWI index was associated with a 15 % increase in the risk of stroke (OR: 1.15, 95 % CI: 1.01-1.32). The further restricted cubic spline analysis demonstrated a positive linear relationship between the TyG-WWI index and stroke risk (p for non-linearity: 0.149). Subgroup analysis showed a more pronounced association between the TyG-WWI index and stroke risk among younger participants and those without coronary heart disease. Finally, sensitivity analysis consistently confirmed the robustness of the study findings.
The findings indicate a positive linear relationship between the TyG-WWI index and stroke risk in the general population.
胰岛素抵抗(IR)与中风风险密切相关。甘油三酯葡萄糖体重校正腰围指数(TyG-WWI)是一种用于评估IR的新型生物标志物。然而,一般人群中TyG-WWI指数与中风风险之间的关系仍未得到探索。本研究旨在探讨一般人群中TyG-WWI指数与中风风险之间的潜在关系。
本研究纳入了1999 - 2018年美国国家健康与营养检查调查(NHANES)项目的22,615名参与者。进行多变量逻辑回归模型、受限立方样条回归、亚组分析和敏感性分析,以探讨一般人群中TyG-WWI指数与中风风险之间的关系。
在纳入研究的22,615名参与者中,812名被确定为中风患者。在调整多个混杂因素后,多变量逻辑回归分析表明,TyG-WWI指数每增加1个标准差(SD),中风风险增加15%(比值比:1.15,95%置信区间:1.01 - 1.32)。进一步的受限立方样条分析表明TyG-WWI指数与中风风险之间存在正线性关系(非线性p值:0.149)。亚组分析显示,在年轻参与者和无冠心病的参与者中,TyG-WWI指数与中风风险之间的关联更为明显。最后,敏感性分析一致证实了研究结果的稳健性。
研究结果表明,一般人群中TyG-WWI指数与中风风险之间存在正线性关系。
