Both Body Mass Index (BMI) and Waist Circumference (WC) can be useful measures in determining obesity and increased health risk. According to the National Institutes of Health, a high WC is associated with an increased risk for type 2 diabetes, dyslipidemia, hypertension and cardiovascular disease when BMI is between 25 and 34.9. A BMI greater than 25 is considered overweight and a BMI greater than 30 is considered obese. WC can be useful for those people categorized as normal or overweight in terms of BMI. (For example, a body builder may have a BMI greater than 25 - making him overweight on the BMI scale - but a WC measurement would show that he is not overweight).
To determine your Waist Circumference, do a waist measurement right at the upper hip bone. The following chart should be helpful in determining the possible risks associated with your BMI and WC.

+ Increased waist circumference can also be a marker for increased risk even in persons of normal weight.
