Abstract

Objective: To individuate a novel sex-specific index, based on Waist Circumference (WC), Body Mass Index (BMI), Triglycerides (TG) and HDL cholesterol (HDL), indirectly expressing visceral fat function. Research design and Methods: Visceral Adiposity Index (VAI) was first modelled on 315 non-obese healthy subjects. Using two multiple logistic regression models, VAI was retrospectively validated in 1,498 primary care patients in comparison to classical cardio and cerebrovascular risk factors. Results: All components of metabolic syndrome increased significantly across VAI quintiles. VAI was independently associated with both cardiovascular (OR:2.45; 95%CI: 1.52-3.95; p<0.001) and cerebrovascular events (OR:1.63; 95%CI: 1.06-2.50; p=0.025). VAI also showed significant inverse correlation with insulin sensitivity during euglycemic-hyperinsulinemic clamp in a subgroup of patients (R(s)= -0.721; p<0.001). By contrast, no correlations were found for WC and BMI. Conclusions: Our study suggests VAI is a valuable indicator of "visceral adipose function" and insulin sensitivity, and its increase is strongly associated with cardiometabolic risk.
