BMI Awareness

Understand the Number & Its Limitations

BMI estimates weight relative to height (kg/m²) as an initial screening tool, not a medical diagnosis.

It does not distinguish muscle mass from fat tissue, and children/teens under 20 require age-specific growth percentiles.

WHO / CDC Adult Thresholds (Age 20+)

Under

<18.5

Normal

18.5–24.9

Over

25–29.9

Obesity

≥30.0
