Nevertheless, research on the relationships between surrogates for IR and BP is limited. In this study, we investigate the associations of these novel IR indices with BP in new-onset hypertension (HTN) and elevated BP individuals.Methods: An overall sample of 55,381 adult subjects was included in Hebei General Hospital. BP and other clinical indicators were measured. Triglyceride glucose (TyG) index, TyG-waist circumference (TyG-WC), TyG-body mass index (TyG-BMI), TyG-waist to height ratio (TyG-WHtR), triglyceride-to-high-density lipoprotein-cholesterol ratio (TG/HDL-C) and metabolic score for IR (METS-IR) were collected as dependable surrogates for IR. Examinees were categorized into four groups based on BP levels. Those involved were classified as quartiles according to the levels of six surrogate IR indices. Logistic regression analysis was adopted to evaluate the impact of substitute IR indicators on BP. The receiver operating characteristic curve (ROC) analysis was performed to explore the predictive ability of the parameters on BP.Results: The incidence of elevated BP, stage 1 HTN and stage 2 HTN was 7.86%, 24.05% and 23.76%, respectively. As the levels of six substitute IR indices rose, so did the BP. In the logistic regression analysis, after full adjustment, all alternative IR indicators were independently related to both stage 1 HTN and stage 2 HTN. Except for TG/HDL-C, other substitute IR indices were strongly associated with elevated BP. ROC curves analysis suggested TyG-WC and TyG-WHtR outperformed other indicators with higher odd ratios and area under the curve (AUC) in all the participants.Conclusion: Increased substitute IR indices were significantly associated with elevated BP in new-onset HTN and elevated BP individuals. TyG-WC and TyG-WHtR could better predict elevated BP, stage 1 HTN and stage 2 HTN.Keywords: insulin resistance, hypertension, elevated blood pressure, triglyceride glucose index, metabolic score for insulin resistance
