1. What is BMI for Children Under 2?

BMI (Body Mass Index) for children under 2 years is calculated the same way as for adults, but the interpretation uses different growth charts specific to this age group. It's an important indicator of growth and nutritional status.

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 under 2 years, BMI should be plotted on the WHO growth charts for proper interpretation.

3. Importance of BMI Calculation

Details: Regular BMI monitoring helps track growth patterns and identify potential undernutrition or overnutrition in infants and toddlers.

4. Using the Calculator

Tips: Measure weight accurately to the nearest 0.01 kg and height/length to the nearest 0.01 m. For infants, length should be measured lying down.

5. Frequently Asked Questions (FAQ)

Q1: How often should BMI be calculated for infants?
A: Typically at each well-child visit (usually at 1, 2, 4, 6, 9, 12, 15, 18, and 24 months).

Q2: What are normal BMI ranges for infants?
A: Normal ranges vary by age and sex. Consult WHO growth charts for specific percentiles.

Q3: How does BMI differ for children under 2?
A: The calculation is the same, but interpretation uses age- and sex-specific growth charts rather than fixed cutoffs.

Q4: What if my baby's BMI seems high or low?
A: Consult your pediatrician. Single measurements are less important than growth trends over time.

Q5: Can I use this for premature infants?
A: Special adjusted age calculations may be needed for premature infants. Consult your healthcare provider.
