Overview

Body Mass Index (BMI) in children and adolescents is interpreted differently than in adults. Because body composition changes as children grow, their BMI is compared against reference curves for children of the same age and sex. These are expressed as percentiles.

Pro Tips

Always use accurate weight and height measurements taken without shoes.
The BMI-for-age chart is used for children starting at 2 years of age.
Discuss percentile results with a pediatrician who can look at the overall growth trend.

Fun Facts

"Percentiles are the most commonly used indicator to assess growth patterns in Children."
"An 85th percentile BMI means the child's BMI is higher than 85% of peers of the same age/sex."
"Puberty causes significant shifts in BMI; tracking over time is more important than a single reading."
"Muscle mass development in teens can sometimes lead to a high BMI without excess body fat."

Formula: BMI = Weight (kg) / [Height (m)]². Status is determined by percentile rank.
