1. What is BMI for Children?

BMI (Body Mass Index) for children is a measure that takes into account a child's age and gender along with their height and weight. Unlike adults, children's BMI is interpreted relative to other children of the same age and gender.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

The result is then compared to UK growth charts to determine the child's percentile.

3. Importance of BMI Calculation

Details: BMI helps identify whether a child is underweight, healthy weight, overweight, or obese for their age and height. It's an important screening tool for potential weight-related health issues.

4. Using the Calculator

Tips:

• Measure height without shoes
• Use current weight without heavy clothing
• Enter the child's exact age in years
• For most accurate results, measure in the morning

5. Frequently Asked Questions (FAQ)

Q2: Is BMI accurate for all children?
A: BMI is a screening tool but may not reflect body fat accurately in very muscular children or those with certain medical conditions.

Q3: How often should I check my child's BMI?
A: Every 3-6 months is sufficient for monitoring growth patterns unless advised otherwise by a healthcare professional.

Q4: What if my child's BMI is high?
A: Consult your GP or pediatrician who can assess overall health, growth patterns, and family history before making recommendations.

Q5: Where can I see the NHS growth charts?
