1. What is BMI for Pediatric Boys?

Body Mass Index (BMI) is a screening tool for weight categories in children and teens aged 2-20 years. For pediatric populations, BMI is age- and sex-specific and is plotted on growth charts to determine percentiles.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

The result is then compared to CDC growth charts for boys to determine the weight category percentile.

3. Importance of BMI Calculation

Details: BMI screening helps identify potential weight problems in children, but is not a diagnostic tool. It should be followed up with more comprehensive assessments when indicated.

4. Using the Calculator

Tips: Enter weight in kilograms, height in meters, and age in years (2-20). For accurate results, measurements should be taken with calibrated equipment.
