1. What is BMI for Teens?

BMI (Body Mass Index) is a measure that uses height and weight to estimate body fat. For children and teens, BMI is age- and sex-specific and is often referred to as BMI-for-age. It's an important screening tool but not a diagnostic of body fatness or health.

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 teen girls, BMI should be interpreted using age- and sex-specific percentiles rather than adult categories.

3. Importance of BMI Calculation

Details: BMI screening can help identify potential weight problems in teens, but it's only one of many factors to consider when evaluating health. Growth patterns, family history, and other assessments are also important.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For most accurate results, measure height without shoes and weight with minimal clothing.

Q4: How often should teens check their BMI?
A: Annual checks are typically sufficient unless recommended more frequently by a healthcare provider.

Q5: What should I do if my teen's BMI is high?
A: Consult a healthcare provider for proper evaluation. Focus on healthy habits rather than weight alone.
