摘要: 背景 三酰甘油-葡萄糖(TyG)指数与肝脏疾病存在密切关联,但目前国内外尚缺乏老年人群TyG指数纵向轨迹与肝脏硬度的关联性研究。 目的 分析TyG指数纵向轨迹与老年人肝脏硬度的关联。 方法 本研究的样本来源于华西老年人群医防融合队列(原"华西老年人群健康队列")的回顾性队列,选取2017—2022年有3次及以上体检记录、三酰甘油及血糖无缺失值的60岁及以上的研究对象,剔除基线患有慢性肝病者后,最终纳入2 736人进行分析。应用群组轨迹模型(GBTM)建立老年人TyG指数的长期纵向轨迹,采用二元Logistic回归模型分析TyG指数纵向轨迹与肝脏硬度的关联。 结果 本研究人群中,肝脏硬度偏高(肝脏硬度值>7 kPa)者共376人(13.7%)。TyG指数纵向轨迹分为5组:低水平稳定(7.96~8.11)337例(12.3%)、中低水平稳定(8.46~8.56)1 172例(42.8%)、中水平稳定(8.94~9.06)921例(33.7%)、中高水平上升(9.31~9.68)268例(9.8%)、极高至中高水平下降(9.27~10.35)38例(1.4%)。二元Logistic回归分析结果显示,调整混杂因素后,与低水平稳定组相比,中水平稳定组(OR=1.94,95%CI=1.13~3.43)、中高水平上升组(OR=3.04,95%CI=1.57~5.99)、极高至中高水平下降组(OR=3.31,95%CI=1.02~10.36)肝脏硬度偏高的风险均增加(P<0.05)。亚组分析结果显示,年龄、性别、BMI、腰围、高血压病史、糖尿病病史与TyG指数不同轨迹间无交互作用(P>0.05)。 结论 老年人群应关注TyG指数变化,当TyG指数持续处于较高水平(8.78)时,应进一步检查肝脏健康状况。

Abstract:

Background

The triglyceride-glucose (TyG) index is closely related to liver diseases. However, there is a lack of studies on the association between the longitudinal TyG index trajectories and liver stiffness in the elderly population, both at home and abroad.

Objective

This study aims to analyze the association between longitudinal trajectories of triglyceride-glucose index and liver stiffness status in elderly individuals.

Methods

The population was derived from the West China Elderly Preventive and Treatment Merging Cohort, comprising 2 736 individuals who participated in three or more health examinations between 2017 and 2022. Participants were aged ≥60 years, had complete triacylglycerol and blood glucose measurements, and had no history of chronic liver disease at baseline. The group trajectory model (GBTM) was applied to establish the long-term longitudinal trajectories of the TyG index, and a binary Logistic regression model was used to analyze the association between the longitudinal trajectories of the TyG index and liver stiffness.

Results

Among the participants, 376 individuals (13.7%) had elevated liver stiffness (LSM>7 kPa). The TyG longitudinal trajectories were divided into 5 groups, including 337 individuals (12.3%) in the low-stable group, 1 172 individuals (42.8%) in the medium-low-stable group, 921 individuals (33.7%) in the medium-stable group, 268 individuals (9.8%) in the medium-high-increasing group, and 38 individuals (1.4%) in the highest-to-medium-high group. Logistic regression analysis showed that, after adjusting for confounding factors, compared to the low-stable group, the medium-low-stable group (OR=1.94, 95%CI=1.13-3.43), medium-stable group (OR=3.04, 95%CI=1.57-5.99), medium-high increasing group, and highest-to-medium-high group (OR=3.31, 95%CI=1.02-10.36) had increased risk for elevated liver stiffness.

Conclusion

Elderly populations should be concerned about changes in the level of the TyG index, and when the TyG index is persistently high (≥8.78), liver health should be further examined.
