Answer

By definition, 2.5% of the population is short. However, the number of children with poor linear growth is higher given the frequency of chronic diseases of childhood. The Utah Growth Study is the largest population-based survey of growth in children published to date. [4] These investigators assessed height and growth velocity in nearly 115,000 American children. Among the 555 children with short stature (defined as height below the third percentile) and poor growth rate (defined as growth velocity < 5 cm annually), only 5% had an endocrine disorder. In addition, 48% of the children with growth hormone deficiency (GHD) or Turner syndrome (TS) in this large cohort had been undiagnosed or untreated.

Parents often suspect an endocrine disorder (eg, GHD) as the major cause of short stature in their child. In fact, the Utah Growth Study confirms that most (95%) children with poor growth (velocity < 5 cm/y) do not have an endocrine disorder.
