Which is also called Body Mass Index?

Correct option is D

The correct answer is (d) Body Mass Index (BMI), also known as Quetelet’s Index, is a widely used measurement in healthcare and fitness to assess an individual’s body composition and overall health status. It is calculated by dividing an individual’s weight in kilograms by the square of their height in meters. The resulting number provides an approximation of a person’s body fatness and helps categorize individuals into different weight status categories, such as underweight, normal weight, overweight, or obese.Quetelet’s Index, named after the Belgian mathematician, astronomer, and statistician Adolphe Quetelet who developed it in the early 19^th century, was originally conceived as a means to assess population-level health and determine the prevalence of obesity. Quetelet recognized that body weight alone was not a sufficient indicator of obesity, as it did not account for variations in height. By standardizing weight relative to height, Quetelet’s Index provided a more accurate measure of adiposity that could be applied across diverse populations.

The formula for calculating BMI is relatively simple: BMI = weight (kg) / height^2 (m^2). This mathematical expression accounts for the fact that taller individuals tend to weigh more than shorter individuals, but their weight is distributed over a larger surface area. As a result, BMI provides a standardized measure that can be used to compare individuals of different heights.
