What is BMI?

BMI (Body Mass Index) is a number calculated from a person’s height and weight. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

Severe Thinness	< 16
Moderate Thinness	16 – 17

BMI for Children & Teens

For children and teens aged 2–20, BMI is interpreted relative to age and sex-specific percentiles. Consult growth charts from health authorities for detailed interpretation.

Why BMI Matters

BMI is an estimated measure of body fat, but it does not directly measure body composition. It serves as a valid screening tool for weight categories that may indicate health risks. Consult healthcare professionals for a more comprehensive assessment.
