1. What is the NHS Child BMI Calculator?

The NHS Child BMI Calculator is a tool to assess whether a child has a healthy body weight for their age, height, and sex. It compares the child's BMI to standard growth charts to determine their percentile.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula adjusted for age and gender:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The result is then compared to UK growth charts to determine the child's weight status percentile for their age and gender.

3. Importance of BMI Calculation for Children

Details: Regular BMI monitoring helps identify potential weight problems in children, allowing for early intervention to prevent health issues associated with underweight or overweight.

4. Using the Calculator

Tips: Enter weight in kg, height in meters, and exact age in years. For most accurate results, measurements should be taken in the morning before eating.
