BACKGROUND AND AIM: To explore the association of triglyceride glucose index-body mass index (TyG-BMI) and its dynamic changes with the risk of hypertension among middle-aged and older Chinese adults based on a large-sample prospective cohort study.
METHODS AND RESULTS: Participants over 45 years old and without a history of hypertension were included from the China Health and Retirement Longitudinal Study registry. Data were collected in 2011 and followed up in 2015. TyG index and TyG-BMI were calculated as ln (triglyceride∗glucose/2) and TyG index∗BMI, respectively. We performed multivariate logistic regression analysis to identify the relationship between the TyG index, TyG-BMI and their dynamic change and the risk of hypertension. In the analyses, 3885 participants were included. After 4 years of follow-up, 1705 (43.89 %) patients developed hypertension. Logistic regression analysis revealed that after adjustments for all potential confounding factors, the highest tertile of baseline TyG index, baseline TyG-BMI, and the dynamic change in TyG-BMI were each associated with higher hypertension incidence than the lowest tertile: OR,1.38, 95 % CI, 1.17-1.63, OR,1.28, 95 % CI, 1.06-1.56, and OR, 1.26, 95 % CI, 1.07-1.48, respectively, whereas TyG index change was not. Moreover, the risk of hypertension increased with increasing levels of baseline TyG index (P for trend < 0.001), baseline TyG-BMI (P for trend = 0.013), and the dynamic change in TyG-BMI (P for trend = 0.006).
CONCLUSIONS: The baseline TyG index, baseline TyG-BMI, and the dynamic changes in TyG-BMI were significantly and positively associated with the risk of hypertension in Chinese adults older than 45 years.
