1. What is Child BMI Percentile?

Child BMI percentile is a measure that compares a child's Body Mass Index to other children of the same age and gender. It provides a better assessment of weight status in children than BMI alone, as children's body composition changes with age.

2. How Does the Calculator Work?

The calculator uses the BMI formula and growth chart data:

Where:

• \( greutate \) — Weight in kilograms (kg)
• \( înălțime \) — Height in meters (m)
• \( IMC \) — Body Mass Index (kg/m²)

Explanation: The BMI value is then compared to standardized growth charts for children of the same age and gender to determine the percentile.

3. Importance of BMI Percentile Calculation

Details: BMI percentile helps identify children who are underweight, healthy weight, overweight, or obese. Early identification allows for timely intervention and healthy lifestyle promotion.

4. Using the Calculator

Tips: Enter weight in kilograms, height in meters, age in years (2-18), and select gender. Ensure accurate measurements for reliable results.
