What is BMI in children?
BMI (Body Mass Index) works differently for children than for adults. In children, BMI is always assessed based on:
- age
- sex
- BMI value
Because children are still growing, their BMI is compared with age-specific reference values. As a result, the same BMI can mean something slightly different at different ages.
