What is BMI? Body Mass Index is calculated using weight and height measurements and is an indicator of body fatness. It is not a direct measurement of fat, but research has shown that BMI measurements correlate to direct measurement. It’s an inexpensive and easy-to-perform way to screen for possible weight issues that may lead to health problems. BMI is measured differently in adults than in children, so it is important to use the proper calculator to find out yours and your child’s separately.
BMI is not used to diagnose health issues, but it can be an early screening tool. Your health care provider may use additional information, such as family history, information about diet and exercise or a measurement of skinfold thickness or other tests to determine whether excess fat is a problem.
