Waist circumference a better indicator of health than BMI
A new study says that the waist circumference, and not body mass index (BMI), is a better indicator of increased risk of death from cardiovascular causes or any cause.
In the study, normal weight individuals who had central obesity i.e. higher waist-to-hip ratio were at a 22% higher risk of death from any cause and a 25% higher risk for death from cardiovascular causes compared to these who are obese according to BMI but did not have central fat accumulation. The study jointly conducted by researchers from the University of Sydney in Australia and Loughborough University in England has been published April 26, 2017 in the Annals of Internal Medicine.
The body mass index is the most commonly used measure of obesity, which is based on height and weight of a person. It is calculated as weight (in kg) divided by the height squared (in cm). But, it does not measure body fat. The correct method to measure obesity is to measure body fat, especially the fat around the abdomen. A high waist-to-hip ratio indicates high amounts of abdominal fat.
