A new obesity scale has been proposed to measure body fat called the Body Adiposity Index, or BAI. The BAI relies on height and hip measurements, and might give a more flexible counterpart to BMI (Body mass index) which is a ratio of height and weight.
BMI is calculated by dividing weight in kilograms by height in meters squared. There can be some inaccuracies though with BMI since men and women with the same BMI can have varying levels of extra fat. Initial testing shows that using BAI instead has more accurate results across gender and different racial groups.
BAI is a complex ratio of hip circumference to height that can be calculated by doctors or nurses with a computer or calculator. Obesity has become rampant, with about 1 in 10 people worldwide considered to be obese, which is more than twice that of the number in 1980. And so, the fight on obesity continues, hopefully with one more tool in the belt to fight with.
