We just launched an ABSI Calculator This one combines PHP, nested AJAX calls and some trickery, supports forward and backward calculations, and allows users combine units from the metric and english systems. Thus users may compute one term of the ABSI equation in function of the others.

About ABSI and why do you want to know more about it

A body shape index (ABSI) is a measure of risk associated with waist circumference developed by Nir Krakauer and Jesse Krakauer in 2012. The authors also have an ABSI tool online.

As stated at Dr. Krakauer’s site, “ABSI is designed to be used together with the better known body mass index (BMI), not to replace it.”.

Studies have associated ABSI with total mortality and cardiovascular risk, indicating that it is useful in assessing cardio-metabolic risks.

A large European cohort found that ABSI achieves better mortality risk stratification than alternative indices of abdominal obesity.
