Considering The Body Mass Index

A consideration of the Body Mass Index, or BMI.

In the last decades, overweight and obesity have become significant issues, particularly in the United States. As weight issues have become more common, tools used in weight control have also become more common. One of the more familiar tools used in weight control is the Body Mass Index, often referred to as the BMI. To describe it in basic terms, the Body Mass Index is a method for determining how close a person comes to having an ideal body weight.

Though the Body Mass Index has become widely familiar over the last decade or so, the notion of using an index to determine ideal body weight has been in existence for over one hundred years. A Belgian statistician in the 19th century came up with a formula that measured obesity. Adolphe Quetelet was the Belgian statistician's name, and the Quetelet Index of Obesity was the name, appropriately, for his obesity measuring formula. The Body Mass Index is, for all intents and purposes, an updated description of the Quetelet Index of Obesity.

The Body Mass Index, or the Quetelet Index of Obesity, uses a mathematical formula to determine a healthy weight. BMI doesn't just measure overweight, but provides classification for exceedingly low body weight as well. An individual's body weight divided by the square of their height is the formula BMI uses to measure body weight health.

In the 1980's, the BMI achieved popularity in the medical field. Prior to this, objective considerations of body weight were based solely on how tall a person was. The problem with this sort of measurement was that it was too narrow in its consideration of a person's body composition, and didn't offer enough information about a person's physical make up and where he or she stood in relation to ideal body weight.

The Body Mass Index gave a thorough consideration of body make up by providing weight ranges, from healthy to unhealthy, and the BMI came to be the standard measure for obesity during the 80's. In the 1990's, as issues of overweight became more significant, US government efforts to encourage better health resulted in Body Mass Index discussion on a much wider scale, and beyond the medical profession.

Calculators that determine BMI are today frequently found on the Net. Virtually anyone can now plug in their height and weight measurements and get a BMI weight composition reading. The BMI was developed as a means for classifying extreme body weights, particularly obesity, so using BMI as a standard measurement for optimal body weight health is inherently problematic. In other words, BMI was essentially developed to categorize the bodies of obese people, and expanding its use beyond this original intent and expecting perfect results is not particularly realistic.
