Definition:
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults.
It is defined as the weight in kilograms divided by the square of the height in metres (kg/m2).
For example, an adult who weighs 70kg and whose height is 1.75m will have a BMI of 22.9.
BMI values are age-independent and the same for both sexes.
