Association of Age Body Shape Index (ABSI) and Body Roundness Index (BRI) with Triglyceride-Glucose-Waist Circumference (TyG-WC) Index as a Cardiometabolic Risk Predictor Among Normal and Overweight Police Officers with normal LDL Level in East Java, Indo

Abstract

Cardiometabolic disorders, including insulin resistance (IR) and visceral adiposity, are common in individuals with normal-low low-density lipoprotein (LDL) levels and non-obese body mass index (BMI). Police officers face higher risks due to occupational stress factors, but conventional screening often overlooks their metabolic risks. The Body Shape Index (ABSI) and Body Roundness Index (BRI) are innovative anthropometric measurements that could potentially offer more accurate predictions for insulin resistance (IR) when examining the combination of triglyceride-glucose index along with waist circumference (TyG-WC). To determine the association of ABSI and BRI with TyG-WC as a surrogate of cardiometabolic risk among Indonesian police officers with normal LDL and BMI. This cross-sectional study enrolled 524 active-duty officers. ABSI and BRI were derived from anthropometric measurements; TyG-WC was calculated from fasting triglycerides, glucose, and waist circumference. Spearman's correlation analysis was conducted, with a level of statistical significance established at p < 0.05. Noteworthy associations were found between ABSI and TyG-WC (r = 0.622, p < 0.001) as well as between BRI and TyG-WC (r = 0.805, p < 0.001). These findings suggest that higher central adiposity and body roundness are associated with elevated surrogate markers of insulin resistance, even in individuals without obesity or dyslipidemia. ABSI and BRI, particularly BRI, robustly associate with TyG-WC in normolipidemic police officers, suggesting their utility for early cardiometabolic risk stratification in high-stress occupations. Routine screening with these indices could enable targeted interventions before overt metabolic disease develops.
