Corpulence index means –
**Core Concept**
The corpulence index, also known as the Quetelet index, is a measure of body mass relative to height, used to assess obesity and body composition. This index takes into account both the weight and the height of an individual, providing a more accurate representation of body fat percentage than other measures.
**Why the Correct Answer is Right**
The corpulence index is calculated by dividing the individual's weight in kilograms by their height in meters squared (kg/m^2). This ratio is then used to categorize individuals into different levels of body mass index (BMI) categories, ranging from underweight to obese. The World Health Organization (WHO) uses the corpulence index as a standard tool for assessing obesity and related health risks.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not accurately describe the corpulence index. The correct formula for the corpulence index involves dividing weight by height squared, not height cubed.
**Option B:** This option is incorrect as it refers to a different measure of body composition, known as the body fat percentage, which is not directly related to the corpulence index.
**Option C:** This option is incorrect as it refers to a different measure of body mass, known as the body mass ratio, which is not a widely used or recognized term in the field of obesity assessment.
**Clinical Pearl / High-Yield Fact**
The corpulence index is a useful tool for clinicians to assess obesity and related health risks, but it has limitations, such as not accounting for muscle mass or body composition. A more accurate assessment of body composition may involve additional measures, such as bioelectrical impedance analysis or dual-energy X-ray absorptiometry (DXA).
**Correct Answer: C. Corpulence index is calculated by dividing weight in kilograms by height in meters squared (kg/m^2).**
