BODY MASS INDEX

What is Body Mass Index (BMI)?

Body mass index (BMI) is a widely used international standard that measures weight to height
ratio to determine obesity. BMI is expressed by the following terms:
Body weight (kg)
BMI =
[Body height (m)]
The BMI is only a general indicator of your health level. As such, accuracies may vary
depending on your body type and composition. Consult your physician to find out more about
your current health.
NOTE
To convert pounds or stone pounds to kilograms, and inches to meters, refer to the
conversion reference on page 13.

Reason
BMI ranges are only based on adult heights.
BMI does not differentiate between fat and muscle, thus making it
inaccurate for persons with high muscle volumes.
This group generates naturally high fat reserves as part of the
pregnancy.
Fat reserves naturally tend to be higher with older persons.
