Obesity in children or adolescents

In infants, children and adolescents, BMI categories for defining obesity vary by age and gender based on WHO growth charts. Children 0 to 5 years have obesity if weight-for-length/height or BMI-for-age is above 3 standard deviations of the median of the WHO Child Growth Standards.

Children aged 5 to 19 years have obesity if BMI-for-age is above 2 standard deviations of the median of WHO Growth Reference for School-aged Children and Adolescents.
