Frequently Asked Questions
Why can't I use adult BMI categories for children?
Children's body composition changes significantly as they grow, so BMI must be interpreted using age- and gender-specific percentile charts (like CDC growth charts) rather than the fixed adult categories (underweight/normal/overweight/obese).
Where do I find percentile charts to interpret this BMI?
The CDC and WHO both publish official growth chart percentile calculators for children and teens — search for "CDC BMI percentile calculator" to plug in this BMI value alongside age and gender for proper interpretation.
Should I be concerned about a child's BMI result?
BMI is just one screening tool — always discuss any concerns about a child's growth and weight with their pediatrician, who can consider the full growth history and context rather than a single BMI snapshot.
