Who discovered the BMI formula in 1972?
The BMI was introduced in the early 19th century by a Belgian named Lambert Adolphe Jacques Quetelet. He was a mathematician, not a physician. He produced the formula to give a quick and easy way to measure the degree of obesity of the general population to assist the government in allocating resources.
When was the BMI chart established?
Fast forward to 1972. The Quetelet Index became known as the Body Mass Index (BMI) when Ancel Keys, a physiologist (and also not a medical professional), stated that it was essential to quantifying health on an individual level.
WHO 1998 BMI classification?
12,22,34 Subsequently, in 1998, the cutoff point between normal and overweight was reduced to a BMI of 25 to bring it into line with the 4 categories in the WHO guidelines. 25,35 Parenthetically, this instantaneously converted millions of Americans from being “normal weight” to being “overweight.”

Who introduced BMI?
Adolphe Quetelet
BMI is very easy to measure and calculate and is therefore the most commonly used tool to correlate risk of health problems with the weight at population level. It was developed by Adolphe Quetelet during the 19th century.
What is the origin of BMI?
BMI is derived from a simple math formula. Lambert Adolphe Jacques Quetelet, a Belgian astronomer, mathematician, statistician, and sociologist, devised it in the 1830s. It aims to estimate whether a person has a healthy weight by dividing their weight in kilograms (kg) by their height in meters (m) squared.
When was the BMI scale updated?
In 1998, the U.S. National Institutes of Health and the Centers for Disease Control and Prevention brought U.S. definitions in line with World Health Organization guidelines, lowering the normal/overweight cut-off from BMI 27.8 to BMI 25.
What was before BMI?
Before the beginning of that decade, doctors generally used weight-for-height tables (separate figures for men and women) that included ranges of weights for each inch of height. The flaw in such measurements was that they were based on weight alone and not body composition.
WHO BMI classification 2020?
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to <25, it falls within the healthy weight range. If your BMI is 25.0 to <30, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obesity range.
What is overweight for a 12 year old?
Overweight children fall between the 85th and 95th percentile, and obese children have a BMI equal to or greater than the 95th percentile. A healthy weight for a 12-year-old girl, therefore, can generally fall anywhere between 65 and 120 pounds.
