BMI was first developed by a mathematician, Aldolphe Quetelet, in the 1830s as a way of defining the average man. Known then as the Quetelet Index, it wasn’t given the term Body Mass Index until 1972 and wasn’t adopted by the World Health Organization until 1997. BMI is the ratio of height to weight. Although it is used by the medical profession as a screening tool for disease, some practitioners feel it is inaccurate. It will label a person as overweight or obese without taking into consideration the amount of muscle as opposed to fat in a person’s body. Opposition also stems from the fact that it was developed 200 years ago and was based on data from mostly white men. BMI does not consider racial, ethnic, age, sex, and gender diversity. A new metric is now being considered and used by many in the medical profession. It is BRI (Body Roundness Index) it measures the relationship between height and roundness (waist measurement). It is a way of measuring central body fat which is more of a predictor of disease. The consensus is that BMI may be overestimating disease risk for muscular athletes and underestimating disease risk for older adults who have replaced muscle for fat. BRI is more concerned with abdominal fat which is more of an indicator of future illness as opposed to BMI which does not consider this to be a part of its calculations. Looks like it is time to start a core exercise routine for the New Year.
