Body mass index, or BMI, is quickly becoming the measurement of choice for many physicians
and researchers studying obesity. BMI uses a mathematical formula that takes into account both
a person's height and weight. BMI equals a person's weight in kilograms divided by height in meters
squared. (BMI=kg/m2).
The link below leads to a convenient chart that allows you to use your weight (in pounds) and height
(in inches) measurements to determining your body mass index. You can use your BMI along with your
waist measurement to then determine your disease risk level as shown in the reference chart displayed
on this page. Please discuss the results of your BMI and risk assessment with your health care provider.
