Measuring Obesity: Body Adiposity Index (BAI)

March 7, 2011

Body Mass Index (BMI) has been used as a measure of obesity from the past 200 years. The BMI is largely used by researchers and doctors across the world. The BMI of a person is calculated by dividing weight in kilograms by height in meters squared.

Scientists have discovered a new measure of obesity called the Body Adiposity Index, or BAI. The BAI is considered as a more flexible alternative to body mass index.

The new measure will help the patients to measure their extra flab without stepping on the scale. Though there were no flaws in BMI but men and women with same BMI might have very different levels of extra flab.

The experts have confirmed the BAI’s accuracy using an advanced device called a dual-energy X-ray absorption or DEXA scanner. The BAI is dependent on the measurements of height and hip. BAI is ratio of hip circumference to height that can be calculated by doctors or nurses with a computer or calculator. The scientists say that the BAI can be used for different racial groups but it requires some modification before it will be used as an alternative of BMI.
