1. What is BMI for Children?

BMI (Body Mass Index) for children is a measure that adjusts weight for height, age, and sex. Unlike adults, children's BMI is compared to growth charts to determine percentiles that indicate healthy weight ranges.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

The result is then compared to CDC growth charts to determine the percentile based on age and gender.

3. Importance of BMI Calculation

Details: BMI screening for children helps identify potential weight problems that may lead to health issues. The CDC growth charts show weight status categories based on percentiles.

4. Using the Calculator

5. Frequently Asked Questions (FAQ)

Q1: Why is BMI different for children than adults?
A: Children's body composition changes as they grow, so their BMI is compared to others of the same age and sex.

Q2: What do the percentile ranges mean?
A: Underweight (<5th), Healthy weight (5th-85th), Overweight (85th-95th), Obese (≥95th percentile).

Q3: When should I be concerned about my child's BMI?
A: Consult a pediatrician if your child is below 5th or above 85th percentile, or if there are sudden changes.

Q4: Are there limitations to BMI for children?
