BMI (Body Mass Index)

BMI (Body Mass Index)

Body Mass Index (BMI), is a general “rule of thumb” measurement to estimating human body fat based on an individual’s weight and height. BMI offers a correlation to other direct methods of measuring body fat, but BMI does not actually measure the percentage of body fat. Basically BMI offers a reliable indicator of body fatness.

BMI is an inexpensive and easy method that can be used as a screening method for unhealthy weight categories that may lead to health issues.

BMI is defined as the individual’s body mass divided by the square of his or her height. The formula universally used in medicine produce a unit of measure of kg/m2. However, I am using the formula below to for BMI which is in lbs/ins.

BMI can also be determined using a BMI chart which displays BMI as a function of weight (horizontal axis) and height (vertical axis) using contour lines for different values of BMI or colors for different BMI categories.

BMI and How it is Used

BMI is not a diagnostic tool. BMI is used as an inexpensive screening tool to help identify possible weight concerns/problems for adults. I you have high BMI you will need to consult your physician conduct a heath assessment to determine if your excess weight is a health risk. In addition to your BMI, your physician might possibly conduct skin fold tests, discuss your daily activity levels, review your diet, and evaluate your family history; just to name a few additional methods of gathering more health information about you.

BMI – The Bottom Line

Calculating BMI is one of the best methods for population assessment of overweight and obesity. Because calculation requires only height and weight, it is inexpensive and easy to use for clinicians and for the general public. The use of BMI allows people to compare their own weight status to that of the general population.
