Since the assessment of the risks of obesity and body mass index body is very approximate (with the same mass index can be a different weight distribution of the body), the United States developed a method of determining these factors with an index volume of the body with the use of three-dimensional scanner.
Measure the height of the individual - for the use of the stadiometer. The person should be without shoes and touch the floor with both heels - otherwise the patient can be elongated by a few centimeters.
Weigh the test. For the purity of the experiment, the object should be drawn.
Divide using a calculator body mass object of study by the square of his height in meters. The resulting value will be required BMI - body mass index of the human.
