Body Mass Index (BMI) also referred to as Quetelet Index is the total measure of body fat in a individual in relation to his height and weight. It is calculated by dividing the said individual’s weight (in kilograms) by the square of his height (in meters).
Body Mass Index= Weight (kg) ÷ Height (m) squared
Therefore, the value of a calculated Body Mass Index should have a unit of kg/m.
The result of a calculated BMI determines if an individual is underweight, normal or obese. Although body fat is the main factor considered in Body Mass Index, level of muscularity also contributes to this. An individual who is underweight may be suffering from malnutrition or some other diseases while an individual who is overweight is prone to cardiac disorders, diabetes, stroke etc. Listed below are Body Mass Index ranges and their matching categories:
- Very Severely Underweight: BMI of less than 15kg/m squared
- Severely Underweight: BMI ranging from 15.0 to 16.0kg/m squared
- Underweight: BMI ranging from 16.0 to 18.5kg/m squared
- Normal: BMI ranging from 18.5 to 25.0kg/m squared
- Overweight: BMI ranging from 25.0 to 30.0kg/m squared
- Moderately Obese: BMI ranging from 30.0 to 35.0kg/m squared
- Severely Obese: BMI ranging from 35.0 to 40.0kg/m squared
