Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity, it provides a rapid visual and anthropometric tool for health evaluation. [1] Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat.
What is the body roundness index and is it better than BMI? Here's how BRI works and how it's used to calculate obesity and a measure of a person's health.
Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions , such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing .
This template allows users to input a height and waist circumference from which the template calculates the body roundness index. These values can be either in centimeters or in inches and feet depending on if metric or imperial is selected via the radio buttons.
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 ...
The Body Roundness Index is similar to the Body Mass Index, but relies on more anthropometric variables. The BRI which was first proposed in 2013 , uses height, weight, waist circumference, and ...
Defined by Wadell in 1935, [1] the sphericity, , of an object is the ratio of the surface area of a sphere with the same volume to the object's surface area: = where is volume of the object and is the surface area.
The body mass index (BMI) considers the height-weight relationship as a health indicator, while the body roundness index (BRI) measures abdominal body fat and height. BMI has often been criticized ...
