Body Mass Index
What is the body mass index (BMI)?
The body mass index is a formula to assess a person's body weight relative to height. It's a useful, indirect measure of body composition because it correlates highly with body fat in most people.
What does my Index score mean?
BMI values less than 18.5 are considered underweight.
BMI values from 18.5 to 24.9 are desirable.
Overweight is defined as a body mass index of 25.0 to less than 30.0. People with BMIs in this range have a moderate risk of developing heart and blood vessel disease, diabetes, and other problems. If your BMI is in this range it is important that you do not gain any more weight, and a small weight loss may be desirable.
Obesity is defined as a BMI of 30.0 or greater (based on criteria of National Institutes of Health). People with BMIs of 30 or more are at high risk of developing heart and blood vessel disease, diabetes, and many other medical problems.
Please Note: If your BMI is in the obese category a modest weight loss may improve your health significantly, even if it does not result in a BMI in the desirable range.
If you fall into the obese category please consult your physician.
If you do not have a physician, please consult our MUSC Med-U-Nurse.
If your BMI falls in the Overweight or Obese categories, you may wish to contact the MUSC Weight Management Center to learn how they can help. 843-792-2273 or 800-553-7489.
Please Note: Because muscle and bone weigh more than fat, the higher weights in the healthy range typically apply to those with more muscle or larger body frames.
