The Body Adiposity Index (BAI) is a unique method of measuring body fat without relying on body weight measurements. Instead, it uses the ratio of hip circumference to height (Bergman et al., 2011). The resulting index value can be equated to the actual percentage of body fat.
Advantages of the BAI
- Simple calculation using standard anthropometrical measurements (hip circumference and height)
- Does not require weight measurement
Comparing BAI to other methods
Although BAI is presented as an alternative to the Body Mass Index (BMI), it has been found to be no better at estimating body adiposity (Freedman et al., 2012). Other measures, such as waist-to-height ratio and skinfold measurements, may be preferable if available.

To calculate the BAI, measure the hip circumference and height using a tape measure and stadiometer. The calculation is as follows:
Adiposity Index = HC / (Ht 1.5 - 18)The higher the score, the higher the levels of body fat. The calculated BAI value is approximately equal to the percentage of body fat.

Summary
The Body Adiposity Index (BAI) is an alternative method for estimating body fatness. Unlike the Body Mass Index (BMI), which relies on body weight, the BAI uses the ratio of hip circumference to height. This calculated index corresponds to the percentage of body fat. Although the BAI has advantages in simplicity and not requiring a weight measurement, it has been found to be no better at estimating body adiposity. Other measures, such as waist-to-height ratio and skinfold measurements, may be preferred.
