Understanding Growth Charts
Age-Specific
Children's BMI is interpreted using growth charts that account for age and gender.
Percentile Focus
Instead of a single number, we look at where your child ranks among others.
Growth Trends
A single BMI measurement is less important than the trend over time.
Clinical Review
Pediatricians use these charts to monitor healthy development.
What is Child BMI?
Body Mass Index (BMI) for children and teens is a measure of weight relative to height. While the formula is the same as for adults, the interpretation is very different.
Growth Spurts
BMI changes as children grow, so age and gender are essential factors.
Screening Tool
It is used to screen for potential weight issues, not to diagnose health conditions.
Did you know?
A child's body fat percentage changes significantly as they grow. This is why a "Normal" BMI number for a 5-year-old might be "Overweight" for a 15-year-old.
Supporting a Healthy Lifestyle
Balanced Diet
Encourage a variety of fruits, vegetables, and whole grains for growing bodies.
Active Play
At least 60 minutes of physical activity daily is vital for health.
Quality Sleep
Growing children need 9-12 hours of sleep depending on their age.
Hydration
Make water the primary drink and limit sugary sodas and juices.
