高甘油-葡萄糖 (TyG) 指数与中国成年人心血管疾病 (CVD) 风险有因果关系. 管理不健康的生活方式和代谢因素,如肥胖和高血压是降低TyG指数和预防心血管疾病的关键.
科学领域:
- 代谢健康 代谢健康
- 心血管疾病流行病学
- 生物统计学 生物统计学
背景情况:
- 胰岛素抵抗与代谢障碍和心血管疾病 (CVD) 有关,但确切的途径尚不清楚.
- 甘油三糖指数 (TyG) 是胰岛素耐药性的标志物.
- 调查TyG指数在心血管疾病途径中的作用对于了解代谢健康至关重要.
研究的目的:
- 调查与提升的TyG指数相关的途径.
- 检查通过提升TyG指数导致心血管疾病发生的途径.
- 专注于中国成年人口.
主要方法:
- 利用了Kailuan研究中的96,506名参与者的数据.
- 应用贝叶斯网络模型,以最大-最小的登和最大概率估计.
- 使用条件概率量化推断因果影响.
主要成果:
- 贝叶斯网络确定了28条与提升的TyG指数相关的路径,以及从TyG指数到心血管疾病的8条路径.
- 提升的TyG指数显示与心血管疾病有因果关系 (11.9%的概率).
- 导致TyG指数升高的关键途径包括不健康的生活方式 (吸烟) 和脂质样本 (LDL-C);导致心血管疾病的关键途径包括超重/肥胖,高血压和CKD (18.5%的概率).
结论:
- 提升的TyG指数与心血管疾病风险增加有关.
- 生活方式和代谢因素的联合控制可以降低TyG指数并预防心血管疾病.
- 研究结果强调了管理新陈代谢健康对心血管保护的重要性.
