body mass index

Abbreviation: BMI
An index for estimating obesity. The BMI can be obtained by dividing weight in kilograms by height in meters squared, or according to the following formula: BMI = (Weight/2.205) / (Height/39.37)2 . In adults, a BMI greater than 30 kg/m2 indicates obesity; a BMI greater than 40 kg/m2 indicates morbid obesity; and a BMI less than 18.5 kg/m2 indicates a person is underweight. The lowest overall death rate is found in people with a BMI of 20 to 24.9 kg/m2.

People with this figure show a significant excess of illness over those in the normal range.
