To investigate the mediating effects and critical influences of triglyceride glucose (TyG) and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) indices on the association of unhealthy lifestyle and hypertension in an occupational population, and to provide a scientific basis for hypertension in occupational populations.
A cross-sectional survey design was employed based on data from the Southwest Occupational Population Cohort. Unhealthy lifestyle was assessed based on scoring for smoking, alcohol consumption, unhealthy dietary patterns, low physical activity, and abnormal BMI. A multivariable logistic regression model was used to analyze the association between the unhealthy lifestyle score and hypertension. Causal mediation analysis was employed to estimate the mediating effects of TyG and TG/HDL-C. Additionally, network analysis was conducted to explore the correlation between among unhealthy lifestyle, TyG, TG/HDL-C, and hypertension.
A total of 24 545 study participants were included, with an average age of (37.37±10.60) years. Regression analysis revealed that the risk of hypertension increased with the number of unhealthy lifestyle factors. Compared with those with no unhealthy lifestyle factors, individuals with all five unhealthy lifestyle factors simultaneously had a 3.06-fold risk of developing hypertension (95% CI: 2.54-3.69). Mediation analysis indicated that TyG and TG/HDL-C mediated 34.25% and 6.64% of the effects, respectively, linking unhealthy lifestyle and hypertension. Among them, TyG emerged as the primary mediating factor and exhibited the highest bridge strength centrality in the network constructed for unhealthy lifestyle, TyG, TG/HDL-C, and hypertension.
Unhealthy lifestyle is associated with an increased risk of developing hypertension and shows a cumulative effect, and TyG is an important mediator and a key node in the network, suggesting that interventions should be carried out to target unhealthy lifestyle and TyG, which may contribute to hypertension prevention.
