Body Mass Index (BMI)

Research has shown that your risk of many chronic diseases such as heart disease, diabetes, and arthritis increases when your BMI is too high. Almost 65% of adults in America have a BMI that is too high. That means that two-thirds of adult Americans are at increased risk for chronic diseases which could be prevented by changing their weight.

What is BMI?

Body Mass Index is a useful tool to assess your weight and disease risk. It is a calculation that takes into account your weight and height.

Why use BMI?

BMI is a reliable indicator of total body fat; too much or too little body fat is not healthy. Calculating BMI is easy and acts as a screening tool for healthy weight and disease risk. It can quickly tell you if you are in a healthy weight range, or conversely if you need to lose or gain weight. Use the link below to find out what your BMI is.

Should BMI be used to assess weight and disease risk for everyone?

BMI is a useful tool for most individuals. However, BMI does not distinguish between muscle and fat. Therefore, it may not be accurate for those individuals who have increased muscle mass such as body builders or athletes. Conversely, BMI may underestimate body fat in older persons who may have lost muscle mass. For anyone with increased or decreased muscle mass, it may be more useful to have your body fat percentage determined by a qualified health professional. In addition, BMI is not an appropriate measure of body fat for pregnant women or children and adolescents who are still growing.
