Inputs

How to use

Enter waist circumference, BMI, and age to compute the ABSI value.

Methodology

Glossary of Terms

  • Waist Circumference: The measurement around your waist.
  • BMI: Body Mass Index, a measure of body fat based on height and weight.
  • Age: Your age in years.

How It Works: A Step-by-Step Example

Consider a person with a waist circumference of 85 cm, BMI of 24, and age of 30 years. Using the ABSI formula, we calculate the ABSI value as follows:

ABSI = 85 / (24^(2/3) * 30^(1/2)) = 0.0800
