BMI, or body mass index, uses height and weight in a mathematical formula to determine a child's weight status compared to other children. BMI is not a measurement of body fat.
To calculate your child's BMI you will need to know their height and weight.
Divide the answer you got from number 1 by the answer you got from number 2.
The answer you get will be your child's BMI. It will most likely be a long decimal, round it to one decimal place.
Children and young adults between the ages of 2 and 20 with a BMI:
A child that has been growing continuously in the 85th-95th percentile range is probably growing normally for his or her body type. A child who has a large upward change in BMI percentile, even if not considered overweight, should be evaluated to determine the cause.
Some experts describe children at or above the 95th percentile as overweight, while other experts describe these children as obese. Similarly, children between the 85th and 94th percentiles may be described as "at risk for overweight" or "at risk for obesity."
See the BMI chart to see where your child's BMI falls.
As always, contact your child's pediatrician with any questions or concerns.
