Body mass index

Topic: Fundamentals

A screening measure calculated as weight in kilograms divided by the square of height in meters (kg/m²). By WHO adult categories, below 18.5 is underweight, 18.5–24.9 normal, 25–29.9 overweight and 30 or above obesity. It does not reflect muscle mass or fat distribution, so pair it with waist circumference.

Also known as:
