ABSTRACT
Objective To explore the correlation between Triglyceride Glucose Index (TyG) and its combined obesity Index and prehypertension in middle-aged and elderly population in China, and to provide a monitoring tool for better hierarchical management of prehypertension population. Methods A total of 5 099 people with non-hypertension were enrolled through the database of the China Health and Retirement Longitudinal Study (CHARLS). Body mass index (BMI), waist circumference (WC) and waist to height ratio (WTHR) were obtained, and TyG-BMI, TyG-WC and TyG-WTHR indexes were calculated by multiplying the TyG index with the three indexes respectively. Logistic regression analysis was used to explore the relationship between TyG index and obesity index and prehypertension. The DeLong method was used to compare the values of Area Under the Curve (AUC) of each index to distinguish their value in identifying prehypertension. Results Compared with the normal blood pressure group, the prehypertension group was older, and the blood pressure was higher. Logistic regression analysis showed that higher levels of TyG-BMI and TyG-WC index were significantly associated with prehypertension. Compared with the lowest quartile array Q1, the OR values of TyG-BMI Q2-Q4 were 1.24 (95%CI :1.03-1.49), 1.40 (95%CI :1.10-1.76) and 1.91 (95%CI :1.43-2.56), while the OR values of TyG-WC index Q2-Q4 group were 1.45 (95%CI :1.19-1.75), 1.49 (95%CI :1.13-1.95), and 2.12 (95%CI: 1.47-3.07), respectively. There was no statistically significant difference in the AUC value between TyG-WC and TyG-BMI (P =0.0998). Conclusion Among the four novel indexes, higher levels of TyG-WC and TyG-BMI are positively correlated with prehypertension. Compared with TyG and TyG-WTHR, TyG-WC and TyG-BMI have the potential to become an effective auxiliary means in the individual hierarchical management of prehypertension in the middle-aged and elderly.
