The Body Roundness Index is a novel body composition measurement that is touted as being a more accurate alternative to Body Mass Index. In a large retrospective study of 33,000 US adults ...
Schematic representation of difference in grain shape. Two parameters are shown: sphericity (vertical) and rounding (horizontal).. Sphericity is a measure of how closely the shape of an object resembles that of a perfect sphere.
While body mass index (BMI) has long been a go-to measure of a person's health, used by doctors and health insurers alike, a new approach is taking hold. Body roundness index, or BRI, is gaining ...
