Childhood obesity is determined by measuring the Body-Mass Index and can be calculated at each pediatrician encounter by simply using the height and weight measurements.  Ask your pediatrician about your child’s BMI to determine their current risk. If the BMI of your child is below the 85%’ile, the child is in the normal range, if your child’s BMI is above the 85%’ile and below the 95%’ile, the child is in the overweight category, and if the child’s BMI is above the 95%, the child is in the obese category.
