Association between triglyceride-glucose index and hypertension in middle-aged and older adults
Aim To investigate the relationship between triglyceride-glucose(TyG)index and the risk of hy-pertension in middle-aged and older adults in China,and to provide scientific basis for the prevention and treatment of hypertension.Methods Data were obtained from the China health and retirement longitudinal study(CHARLS)in 2011.A multi-stage stratified sampling method was used to select participants.Restricted cubic spline regression model was used to analyze the dose-response relationship between TyG index and the risk of hypertension.Multivariate unconditional Logistic regression model was used to evaluate the association between TyG index and the risk of hyperten-sion.Results A total of 9 987 subjects were included in the analysis,with an average age of(59.16±9.43)years,including 4 707 males(47.13%).The restricted cubic spline regression model showed that the risk of hypertension in-creased with the elevation of TyG index,and there was a linear association(overall association test P<0.000 1,non-linear association test P=0.201 9).The results of multivariate Logistic regression model showed that compared with Q1(TyG index<8.23),the OR(95%CI)of hypertension with Q2(8.23≤ TyG index<8.59),Q3(8.59 ≤ TyG index<9.04)and Q4(TyG index≥9.04),were 1.09(0.95~1.26),1.53(1.33~1.76)and 1.77(1.52~2.06),respectively.Conclusions With the increase of TyG index,the risk of hypertension gradually increased.TyG index may be an inde-pendent risk factor of hypertension.
