摘要: 背景胰岛素抵抗(IR)是高血压的核心病理生理机制,三酰甘油葡萄糖(TyG)指数被视为IR的一项新型替代指标,目前TyG指数对高血压发病的影响尚存争议,且纵向研究资料有限。目的探讨TyG指数对高校教师高血压发病风险的影响。方法基于2015年1月至2019年12月某高校教师健康体检资料,采用回顾性队列研究方法,选取连续参与健康体检且基线血压正常的602人作为研究对象。通过一般资料收集、体格检查,采集研究对象人口学特征、既往疾病史、用药史等信息,同时采集研究对象历年静脉血以获得实验室指标。将研究对象按照TyG指数四分位数法分为4组(Q1~Q4),计算TyG指数各组高血压累积发病率。运用广义估计方程(GEE)模型探讨TyG指数对高血压发病的影响,并按性别、年龄、BMI特征进行TyG指数对高血压影响的亚组GEE分析。结果5年间检出高血压174例,累积发病率为28.9%。其中男性和女性5年高血压累积发病率分别为37.4%(101/270)、22.0%(73/332),二者比较,差异有统计学意义(χ2=17.23,P<0.001)。TyG指数Q1~Q4组高校教师的高血压累积发病率分别是16.8%(25/149)、24.7%(37/150)、32.9%(50/152)、41.1%(62/151),随着TyG水平的升高,高血压发病率呈上升趋势(χ2趋势=23.97,P<0.001)。多因素GEE分析结果显示,在调整性别、年龄、BMI、γ-谷氨酰转肽酶、丙氨酸氨基转移酶、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、尿酸、尿素氮后,与TyG指数Q1组相比,Q3、Q4组发生高血压风险升高〔Q3组OR(95%CI)=1.546(1.026,2.330);Q4组OR(95%CI)=1.872(1.209,2.901)〕。亚组分析显示,与女性相比,男性TyG指数Q4组高血压发病风险更高(P<0.05);在45~54岁组和体质量正常组,TyG指数Q3、Q4组高血压发病风险均更高(P<0.05)。结论TyG指数是高血压发病的独立危险因素,升高的TyG指数可增加高血压发病风险,其对男性、45~54岁人群和体质量正常人群的作用效应更为明显,可作为高血压早期筛查的工具。

Abstract: Background

Triglyceride-glucose (TyG) index is regarded as a novel alternative to insulin resistance (IR) , a core pathophysiological mechanism of hypertension. However, it is still controversial about the association of TyG index with hypertension, and relevant longitudinal research is limited.

Objective

Attempt to examine the association of TyG index with hypertension among teachers from a university.

Methods

A retrospective cohort study was conducted from January 2015 to December 2019. Participants (n=602) were teachers from a university who had normal blood pressure and consecutively underwent the annual physical examinations. Their physical examination data were collected, including demographic characteristics, anamnesis, medication history, and biochemical indices in venous blood. The cumulative incidence of hypertension was calculated and compared across groups〔Q1-Q4 (first to fourth quartiles) 〕 of TyG index quartiles. The association of TyG index with hypertension was analyzed, and further analyzed by sex, age, and BMI using generalized estimating equation (GEE) .

Results

A total of 174 cases were found to have hypertension during the 5 years, with 5-year cumulative incidence of hypertension of 28.9%. The 5-year cumulative incidence was 37.4% (101/270) for males and 22.0% (73/332) for females with a statistical difference (χ2=17.23, P<0.001) . The 5-year cumulative incidence of hypertension in Q1 to Q4 groups was 16.8% (25/149) , 24.7% (37/150) , 32.9% (50/152) and 41.1% (62/151) , respectively, revealing that the cumulative incidence of hypertension increased with the elevation of TyG (χ2=23.97, P<0.001) . Multivariate analysis using GEE approach showed that compared to Q1 group, the risk of hypertension significantly increased in Q3 group〔OR (95%CI) =1.546 (1.026, 2.330) 〕 and Q4 group〔OR (95%CI) =1.872 (1.209, 2.901) 〕 after adjusting for gender, age, BMI, γ-GGT, ALT, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, uric acid, urea nitrogen. Further analysis revealed that in individuals with the fourth quartile of TyG index, men had higher risk of hypertension than women (P<0.05) . In individuals aged 45-54 years, those with the third or fourth quartile of TyG index had higher risk of hypertension (P<0.05) . In individuals with normal weight, those with the third or fourth quartile of TyG index had higher risk of hypertension (P<0.05) .

Conclusion

Elevated TyG index may be associated with increased risk of hypertension, so it could be used as an independent predictor of hypertension in general population, especially in men, 45-54-year-olds, or those with normal weight. And measurement of TyG index may be used to early screening for hypertension.
