BMI
Body mass index (BMI) can be used to screen patients because the test is simple, correlates to fatness, and applies to both men and women. The BMI may not apply to some individuals with more than normal muscle mass and acceptable levels of body fat. In some ethnic groups, such as Pacific Islanders, BMI overestimates fatness and risk. For children and the elderly, BMI may be misleading since the muscle and bone to height relationship is changing.
