Body Adiposity Index or simply BAI is the calculation of body fat in adults. Unlike BMI, BAI doesn’t need weight to estimate fat, rather it uses the hips size to calculate the body fat. This index is calculated by dividing the hip circumference by one and a half of their height in meters and subtracting them all to 18.
BAI is different to both males and females. For a male of age 20 to 39, 8% to 21% is the healthy fat level. In contrast, for a female of age 20 to 39, 21% to 33% is healthier.
Body Adiposity Index for Women
|20-39||Less than 21%||21% to 33%||34% to 39%||Greater than 39%|
|40-59||Less than 23%||23% to 35%||36% to 41%||Greater than 41%|
|60-79||Less than 25%||25% to 38%||39% to 43%||Greater than 43%|
Body Adiposity Index for Men
|20-39||Less than 8%||8% to 21%||22% to 26%||Greater than 26%|
|40-59||Less than 11%||11% to 23%||24% to 29%||Greater than 29%|
|60-79||Less than 13%||13% to 25%||26% to 31%||Greater than 31%|
As already mentioned, the BAI calculation is gender and age-specific. They are different because of the difference in growth patterns in males and females.
Steps to Calculate BAI
- Select your gender and enter your age.
- Enter your hip circumference (cm) and your height in feet and inches.
- Click on calculate, and you will see your BAI score below alongside the category you come into.
Note: The results indicated by the BAI or Body Adiposity Index calculator are not to be relied upon to make health-related choices. Do consult with your doctor once before making any specific changes to your diet and such.
