Evaluation of Short Stature in Children and Adolescents

Short stature is a common presentation to pediatricians with a significant overlap between physiology and pathology. Thus, while most short children have a physiological cause, growth failure may be the only manifestation of severe underlying disease. Growth failure evaluation aims to avoid unnecessary investigations in children with a physiological cause without missing pathology. Guidelines for the evaluation of short stature allow stepwise evaluation but are limited by their resource-intense nature. An objective application of anthropometric indices and careful clinical evaluation allows rational growth failure workup. The use of height standard deviation score (SDS) for determining the need for evaluation (no evaluation above -2, follow-up between -2 to -3, and immediate workup with height below -3), corrected height SDS to identify familial short stature (above -1.5), height SDS for bone age for constitutional delay of puberty and growth (above -2), and BMI SDS for nutritional pattern growth failure (below -1) helps reduce the burden of investigations. The present review provides a framework for comprehensive growth evaluation across resource levels and settings.
