摘要:
目的: 分析三酰甘油葡萄糖(triglyceride-glucose,TyG)指数与新发脂肪性肝病(fatty liver disease,FLD)之间的相关性,从而为FLD的防治提供依据。方法: 采用回顾性队列研究设计,通过便利抽样选取2018年度在我院体检中心进行健康体检的受试者作为基线观察人群,根据TyG指数四分位数分为Q1、Q2、Q3、Q4四组,随访至2020年度。每年收集1次健康体检资料,最终纳入958名受试者,采用Cox比例风险模型和Spearman相关分析TyG指数与新发FLD的关系。结果: FLD的累积发病率随着TyG指数的增高而升高(P<0.05)。Cox比例风险模型经校正年龄、性别、体质量指数(body mass index,BMI)等因素后,Q2、Q3、Q4组FLD发病风险分别为Q1组的2.107 [95%置信区间(confidence interval,CI):1.317~3.373]、2.598 (95%CI:1.659~4.069)和3.171倍(95%CI:2.036~4.938)。Spearman相关分析显示TyG指数与发生FLD呈正相关,且相关性最高(r=0.302,P<0.001)。结论: FLD的发病风险随着TyG指数的增加而升高,TyG指数是预测FLD发生的有效指标。
