For decades, clinical practice relied on deceptively simple anthropometric measures—most notably body mass index (BMI), waist circumference, waist-to-hip ratio, and waist-to-height ratio (WHtR)—to assess adiposity and estimate cardiovascular risk. Among these, WHtR has emerged as a simple and robust marker of central adiposity, showing good performance in predicting cardiometabolic risk across different populations [1]. While these tools are undeniably practical and remain useful at the population level, their limitations have become increasingly evident when applied to individual patients.
