**Question:** Kupuswamy index includes the following except

A. Body mass index (BMI)
B. Waist circumference (WC)
C. Hip circumference (HC)
D. Waist-to-hip ratio (WHR)

**Core Concept:** Kupuswamy index is a measure of obesity assessment in the Indian population, which combines BMI, WC, and HC. It is used to predict obesity-related health risks.

**Why the Correct Answer is Right:** The Kupuswamy index is a specific formula tailored to the Indian population and includes BMI, WC, and HC to assess obesity-related health risks accurately.

**Why Each Wrong Option is Incorrect:**

A. **Body mass index (BMI):** BMI is a widely used index to assess obesity, but it does not differentiate between fat and muscle mass, making it less specific for Indians.

B. **Waist circumference (WC):** Although WC is a useful indicator of abdominal obesity, it does not account for the distribution of body fat and does not consider the impact of sex and age on obesity.

C. **Hip circumference (HC):** HC is less sensitive than WC in identifying abdominal obesity, which is the primary risk factor for cardiovascular diseases.

D. **Waist-to-hip ratio (WHR):** WHR is a more reliable indicator of central obesity than WC alone. However, the Kupuswamy index is designed specifically for the Indian population, incorporating BMI, WC, and HC to account for sex and age variations.

**Clinical Pearl:** In assessing obesity-related health risks, the Kupuswamy index is a more accurate and relevant tool for the Indian population compared to BMI, WHR, and WHtR. However, each of the included measurements (BMI, WC, and HC) has its own limitations, emphasizing the importance of considering multiple parameters for a comprehensive obesity assessment.

**Correct Answer:** WHtR (waist-to-height ratio)

Core Concept: Waist-to-height ratio (WHtR) is a measure of central obesity, which is a risk factor for cardiovascular diseases. It is calculated by dividing waist circumference by height (WC/height). However, the Kupuswamy index is a more suitable index for assessing obesity-related health risks in the Indian population.

**Why WHtR is Incorrect:** While WHtR is a valid indicator of central obesity, the Kupuswamy index considers BMI, WC, and HC, which are more relevant to the Indian population and take into account sex and age variations. The Kupuswamy index is a more accurate and precise tool for predicting obesity-related health risks in India.
