Overview

Short stature is defined as a condition in which the height of an individual is in the 3rd percentile for the mean height of a given age, sex, and population group. According to Ranke (1996), “Short stature is defined as a condition in which the height of an individual is two standard deviations (SD) below the corresponding mean height of a given age, sex and population group.”

Classification

There are two types of short stature,

Proportionate short stature (PSS)

Proportionate short stature (PSS) is when the person is small, but limbs and trunk height are in proportions.

Disproportionate short stature (DSS)

Whereas in disproportionate short stature (DSS), this proportion is absent, and the individual shows a great difference in his sitting and standing height.
