The formula to calculate the Ponderal Index (PI) is:
\[ \text{PI} = \frac{m}{h^3} \]
Where:
The Ponderal Index (PI) is a calculation used to assess a person's leanness or corpulence. It is similar to the Body Mass Index (BMI), but it is considered to provide a more accurate representation of an individual's leanness. The PI is calculated by dividing the individual's mass by the cube of their height. The result is then compared to a reference range to determine whether the individual is underweight, normal weight, overweight, or obese. The PI is often used in medical and health-related research to study the relationship between body size, health, and disease risk. It is particularly useful in studies involving children and adolescents, as it takes into account the changes in body composition that occur with growth and development.
Let's assume the following values:
Using the formula to calculate the Ponderal Index:
\[ \text{PI} = \frac{70}{(1.75)^3} \approx 22.86 \]
The Ponderal Index is approximately 22.86.
