BMI Formula:
From: | To: |
BMI (Body Mass Index) for babies and toddlers is a measure that compares their weight to their height. For children under 2, it's called weight-for-length rather than BMI, but the calculation is similar. It helps assess whether a child's weight is appropriate for their height and age.
The calculator uses the standard BMI formula:
Where:
Explanation: The result is then compared to WHO growth standards to determine the percentile for the child's age and sex.
Details: Tracking BMI in early childhood helps identify potential weight problems that could lead to health issues. It's particularly important for monitoring growth patterns over time.
Tips: Enter weight in kg, height in meters, and age in years. For infants, measure length while lying down. Use accurate measurements for best results.
Q1: What's a healthy BMI for a baby boy?
A: Healthy BMI varies by age. Generally between the 5th and 85th percentiles on growth charts is considered healthy.
Q2: How often should I check my baby's BMI?
A: Regular check-ups with your pediatrician will include growth measurements. There's usually no need for frequent BMI checks at home.
Q3: What if my baby's BMI is high?
A: Consult your pediatrician. Rapid growth may be normal, but consistently high BMI may need attention.
Q4: Is BMI different for premature babies?
A: Yes, growth charts for premature babies adjust for gestational age. Use corrected age until about 2 years.
Q5: What are limitations of BMI for babies?
A: BMI doesn't distinguish between muscle and fat. Some healthy, active toddlers may have higher BMIs.
