Association between triglyceride glucose combined with body mass index and hypertension in the NHANES 2017 to 2020

Triglyceride glucose-body mass index (TyG-BMI), as a new surrogate index for evaluating insulin resistance (IR), has rarely been studied with the incidence rate of hypertension (HTN). This study aims to explore the correlation between TyG-BMI and HTN in American adults, to find a cost-effective and convenient marker to guide early prevention of HTN. We performed this cross-sectional study based on the NHANES database from 2017 to 2020. A multivariate logistic regression model was used to analyze the correlation between TyG-BMI and the prevalence of HTN. Additionally, stratified analysis was performed to test the robustness of the results. 3,069 eligible participants were included in our study (48.8% male, mean age 50.0 ± 17.2 years), and multivariate logistic regression analysis showed that TyG-BMI was maintained positively correlated with HTN after fully adjusting covariates. For every 10-unit increase in the TyG-BMI, the risk of HTN increases by 4.3% (95% CI: 1.007-1.08, P = 0.018). When TyG-BMI was represented as a Quartile, the relationship between TyG-BMI and increased risk of HTN remained significant, which were statistically significant for each model. Stratified analyses suggested that the correlation between TyG-BMI and HTN was more pronounced in those aged 60 years or older (P < 0.05). The correlation between TyG-BMI and HTN remained stable in all strata except the age subgroup (P > 0.05). TyG-BMI is significantly associated with HTN among American adults. Early monitoring of TyG-BMI may help to monitor early the risk of hypertension.
