Corpulence Index Values for Adults and Adolescents
Category CI (kg/m3)
Normal (Typical) 11 to 15
The Corpulence Index (CI), also known as the Ponderal Index (PI), is a means of determining a person's corpulence level. Swiss physician Fritz Rohrer initially introduced this concept in 1921 (West, 2019) as the "Corpulence measure," which is why it is sometimes called Rohrer's Index (RI). This tool calculates CI values without age corrections, making these applicable solely for adults and adolescents.

In newborns and infants, the CI is approximately twice as high as in adults and adolescents, owing to their relatively shorter legs. As a result, CI is typically computed in g/cm3 and adjusted for age. For newborns, H is computed as the crown-to-heel length. Although a CI of 12 is typical beyond infancy, age adjustments are still necessary. See also Koury, Berg, & Calle (1990) and Nili, Makipour, & Mobini (2003).
