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.
Why was the BMI created?
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.
What is BMI intended for?
BMI is an inexpensive and easy screening method for weight category—underweight, healthy weight, overweight, and obesity. BMI does not measure body fat directly, but BMI is moderately correlated with more direct measures of body fat 1,2,3.
When did doctors start using BMI?
In 1985, the National Institutes of Health (NIH) started using BMI to define obesity in the United States. At first, the thresholds were more conservative, but by 1998, the NIH started using the aforementioned easier categories we know today to encompass all ages, both sexes, and every culture.
Who gave the concept of BMI?
The BMI was invented by Belgian polymath Adolphe Quetelet in the 1800s, and consequently is sometimes known as the Quetelet index. The BMI is calculated by dividing your weight in kilograms (kg) by your height in metres squared (m2).
Why is BMI so inaccurate?
BMI is not an accurate predictor of health because it does not account for body fat percentage or body fat distribution. Measurements that are more accurate than BMI at predicting health outcomes include blood pressure, waist circumference, and cholesterol levels.
What is full form of BMI * 1 point?
The full form of BMI is Body Mass Index. It is a method of measuring through which individuals are classified into the following categories: obese, overweight, normal weight and underweight. Its the proportion of your weight in kg (kilogram) to the square of your height in m(meters).
Who is underweight?
Underweight is defined as low weight-for-age. A child who is underweight may be stunted, wasted or both. Micronutrient deficiencies are a lack of vitamins and minerals that are essential for body functions such as producing enzymes, hormones and other substances needed for growth and development.
Can BMI be wrong if you are muscular?
Crucially, BMI doesnt distinguish between fat and muscle and studies have found it unreliable.
Can you have a high BMI and still be healthy?
Yes as long as the person is declared “healthy” after a physical examination. Muscular athletes often have high BMIs but are healthy. There are many healthy people that have a higher BMI than the suggested healthy range of 18.5-24.9 due to a higher muscle mass than overweight individuals.
