Percentile indicates the relative position of a child’s BMI number among other children of the same sex and age. BMI percentile is then checked for weight status category to give some indication of relative risk for overweight.

7 Weight Status Category Weight status categories are then assigned according to the BMI percentiles. Weight Status Category BMI Percentile Range UnderweightLess than 5 th percentile Healthy weight5 th to less than 85 th percentile At risk of being overweight 85 th to less than 95 th percentile OverweightEqual to or greater than 95 th percentile
