Do surrogate insulin resistance indexes predict the prevalence of carotid atherosclerosis in normal-weight individuals?
The Chinese visceral adiposity index (CVAI) is an independent and superior predictor of carotid atherosclerosis in normal-weight individuals, suggesting its utility for early cardiovascular risk screening in this population.

Introduction The aim of this study was to assess the correlation between surrogate insulin resistance (IR) indexes and carotid atherosclerosis (CA) in normal-weight populations, as well as compared their ability to predict CA. Method A total of 26,795 middle-aged and older adult individuals with normal body weights were included. Triglyceride-glucose index (TyG), TyG-body mass index, TyG-waist circumference (TyG-WC), TyG-waist-to-height ratio (TyG-WHtR), visceral adiposity index, Chinese VAI (CVAI) and lipid accumulation product (LAP) were determined using established formulas. The associations between these surrogate indexes and CA were assessed using logistic regression models and restricted cubic spline (RCS) analysis. Receiver operating characteristic curves were utilized to compare the performance of these indexes for predicting CA. Result The levels of all seven surrogate indexes of IR were significantly higher in normal-weight individuals with CA than in those without CA ( p 0.001). In the full-adjusted model, only CVAI, TyG-WC, TyG-WHtR and LAP were significantly associated with CA, with the adjusted odds ratios (95% CI) of CA being 1.25 (1.20–1.30), 1.18 (1.14–1.23), 1.20 (1.16–1.25) and 1.25 (1.18–1.32) for each one standard deviation increase in CVAI, TyG-WC, TyG-WHtR and LAP, respectively. RCS analysis revealed a significant increase in the prevalence of CA among normal-weight individuals with CVAI 89.83, LAP 28.91, TyG-WHtR 4.42 and TyG-WC 704.93. The area under the curve for CVAI was significantly greater than for other indexes ( p 0.001). Conclusion CVAI, TyG-WC, TyG-WHtR and LAP were independently associated with the prevalence of CA. Specifically, CVAI may be the most appropriate predictor of CA in normal-weight individuals.
Liu et al. (2023) conducted a cross-sectional in Carotid atherosclerosis in normal-weight individuals (n=26,795). Chinese visceral adiposity index (CVAI) vs. Lower levels of CVAI was evaluated on Prevalence of carotid atherosclerosis (OR 1.25, 95% CI 1.20-1.30, p=<0.001). In normal-weight individuals, a one standard deviation increase in the Chinese visceral adiposity index (CVAI) was independently associated with a 25% higher odds of carotid atherosclerosis (OR 1.25).
