BMI stands for Body Mass Index. BMI uses your child’s weight and height to see if your child is too heavy, too thin or a good weight for his/her age. It is given to you as a number. You can also see how your child compares with children who are the same age with the BMI-for-Age percentile.
We know that kids who are overweight or obese are more likely to have medical problems. Sometimes, families may not even know the child has a problem.
