Description
  Body Mass Index (BMI) is a number calculated from a person’s weight and height. 
  BMI is used as an screening tool to identify possible weight problems for adults/childs. However, BMI is not a diagnostic 
  tool.                   
  BMI correlates to direct measures of body fat, such as underwater weighing and dual energy x-ray 
  absorptiometry (DXA).  
  BMI can be considered as an alternative for direct measures of body fat. 
  Additionally, BMI is an inexpensive and easy-to-perform method of screening for weight categories that may lead to 
  health problems.
