Enter information in height and body weight column; select
appropriate gender and measurement units. Click "Calculate".
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. |
