How does a child's BMI (Body Mass Index) differ from an adult's BMI?

Age and gender are taken into account when calculating a child's BMI using the CDC (Centers for Disease Control) percentiles. Equal to or greater than the 85th percentile is classified as 'overweight' and equal to or greater than the 95th percentile is classified as 'obese'.
