Is BMI Designed for Men and Women Over the Age of 18 Only?

The Body Mass Index, or BMI, can be used for both children and adults. For adults, BMI is measured via a calculation using the person's weight and height. For children between the ages of 2 and approximately 19, the BMI calculation is more complex.

When measuring the BMI of someone under the age of 20, the BMI measurement and the age of the child/teen is plotted on a growth chart, to get a percentile ranking. The percentile ranking is used to determine where the child/teen fits in the BMI range of other children/teens of the same age. From that point, it can be determined whether the child is under- or overweight, or in a healthy weight range.
