Formula:
ABSI = WC / (BMI^2/3 × Height^1/2)
Where WC and Height are in meters, BMI in kg/m²

What is ABSI?

A Body Shape Index was developed by Krakauer & Krakauer (2012) to capture the mortality risk from abdominal obesity that BMI alone misses. It measures whether your waist circumference is larger or smaller than expected for your BMI and height. A higher ABSI indicates more abdominal fat and higher mortality risk.
