1. What is BMI for Children?

BMI (Body Mass Index) for children is a measure that adjusts for age and gender, as children's body composition varies as they grow. Unlike adults, children's BMI is compared to growth charts specific to their country, age, and sex.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Note: For children, the raw BMI number must be plotted on country-specific growth charts to determine the percentile, which indicates whether the child is underweight, healthy weight, overweight, or obese.

3. Importance of BMI Calculation

Details: BMI screening for children helps identify potential weight problems that could lead to health issues. However, it's just one tool among many for assessing a child's growth and health.

4. Using the Calculator

Tips:

• Measure weight in kilograms (1 kg = 2.2 lbs)
• Measure height in meters (1 m = 3.28 feet)
• For accuracy, measure without shoes and heavy clothing
• Select the appropriate country standard (UK or Malaysia)

5. Frequently Asked Questions (FAQ)

Q1: Why are there different standards for UK and Malaysia?

Q2: What BMI percentile is considered healthy?
A: Typically, 5th-85th percentile is healthy weight, 85th-95th is overweight, and ≥95th is obese. Underweight is <5th percentile.

Q4: How often should children's BMI be checked?
A: Annually is typical, but more frequently if weight concerns exist. Always consult a healthcare provider.

Q5: Where can I find the growth charts?
A: UK charts are available from the Royal College of Pediatrics, Malaysia charts from the Ministry of Health.
