Q: What is BMI for age?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
BMI-for-age is a growth chart used for children and teens (ages 2-20) that plots Body Mass Index against age to assess healthy development. Unlike adult BMI, it uses percentiles:
- Below 5th percentile: Underweight
- 5th-85th percentile: Healthy weight
- 85th-95th percentile: Overweight
- Above 95th percentile: Obese
It accounts for normal growth patterns and gender differences during development.
