What Is Body Adiposity Index

Body Adiposity Index (BAI) is a process of measuring human body fat. BAI is different from BMI. BMI is usually defined as the proxy measurement of body fat but the calculation of BAI is carried out without using body weight. The calculation of BAI is numerically equal to the percentage of the body fat for both men and women of different groups.

Formula For Body Adiposity Index:

The calculation of BAI is carried out by the given formula:

BAI = {circumference of hip in centimeters/ (height in meters) * square root of height} – 18

The measurement of hip circumference to the height of the person in meters is divided and then multiplied by square root of the height and then subtracted by 18.

For example, if a man is 5-foot 9-inches tall and weighs 210 pounds with hip circumference of 44.4inches then his BMI will be 31 whereas BAI will be 31.2. Similarly, women of 5-foot 4-inches and a weight of 127 pounds and hip circumference of 37 inches will have a BMI of 21.7 whereas the BAI will be 27.8. Therefore, BAI is capable of giving a more accurate reading of the total amount of the fat present in the body.

Advantages Of BAI:

  • BAI provides the approximate percentage of the fat present in the body.
  • It is different for both male and females having similar percentage of fat tissues in them.
  • As this calculation do not require any weighing process so it can be calculate in remote places also where scaling machines are not readily available.
