Data Source and Methodology

All calculations are based strictly on the formulas and data provided by the CDC Child and Teen BMI Calculator.

The Formula Explained

\[ BMI = \frac{weight \, (kg)}{height \, (m)^2} \]

Glossary of Terms

How It Works: A Step-by-Step Example

Consider a 10-year-old male child who is 140 cm tall and weighs 35 kg. Using the formula:

\[ BMI = \frac{35}{1.4^2} \approx 17.86 \]

Frequently Asked Questions (FAQ)

What is BMI?

The Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults. For children, it is used as a percentile.

Why is BMI important for children?

BMI is an easy-to-perform and useful screening tool for identifying possible weight problems in children.

How accurate is BMI for children?

While BMI is a useful indicator, it is not a direct measure of body fat and should be considered alongside other factors.

What are the normal BMI ranges for children?

Normal BMI ranges vary by age and gender. It is important to compare BMI with age-specific percentiles.

How often should BMI be checked for children?

BMI should be checked regularly as part of routine health assessments.
