Please note that the IMA is not the BMI (Body Mass Index). This is a different measurement, you will find more information on the IMA at the bottom of the page.
Fill in your height (in cm) as well as your hip circumference (in cm) and we will calculate your IMA, ie the percentage of adipose mass (fat mass), in your body.

ORIGINS OF THE IMA & EXPLANATIONS
As the BMI is a measure that has many flaws & limitations, the IMA has been defined as an alternative indicator. The study that presents the AMI (1) dates from 2011. It is therefore a recent indicator , on which the scientific community therefore has little perspective.
The researchers who presented the IMA (or BAI , in English, for Body Adiposity Index ) estimate that the circumference of the hips as well as the size is very strongly glued to the percentage of fat in the human body. The IMA in fact directly calculates the percentage of adipose mass (i.e. fat mass) .
Like the BMI, this calculation requires only objective information, without any complexity. The IMA is the result of a study of 1700 individuals. Interpretation of IMA, however, is slightly more complex than BMI. Indeed, the interpretation is made according to sex and according to age (even though the BMI does not make any differentiation in terms of interpretation, whether it is a question of sex or age).
The formula for obtaining the value of the IMA, in percentage, is as follows:
I n d i c e of _ M a s s s A d i p e u s e = ( H / ( T ∗ T ‾‾√ 2 ) ) − 18
Where the height (T) is expressed in meters and where the hip circumference (H) is expressed in centimeters.
However, following the use of this formula, it is advisable to carry out an interpretation according to the table provided below.
