title: Disorders of childhood growth and development: failure to thrive versus short stature.
abstract: Failure to thrive (FTT) describes retarded growth in height and weight, whereas short stature (SS) involves comparison of a child or adolescent's height to that of a reference group or to his or her own height across time. To identify either condition in infants, children, and adolescents, the family physician should focus on accurate measurement of length/height and weight as well as careful plotting and assessment of the rate of linear growth and weight gain based on World Health Organization standards (from birth to 2 years) and Centers for Disease Control and Prevention charts (from age 2 years). Identification of the etiologies of FTT and SS is complex, requiring consideration of such factors as birth weight, prematurity, and familial height. FTT can result from inadequate caloric intake (eg, caused by difficulties with nursing, limited food availability, or incorrect formula preparation), inadequate caloric absorption (eg, resulting from metabolic, gastrointestinal, or other medical conditions), or excessive caloric expenditure/ineffective utilization (eg, due to hyperthyroidism, diabetes, pulmonary or cardiac conditions). Short stature can be due to a primary growth disorder, such as bone disease or chromosomal syndrome; a secondary factor, such as a chronic medical or endocrine disorder; or an undetermined etiology. The management of FTT and SS requires attention to a combination of medical and behavioral/social issues (eg, treating underlying conditions, assisting with the feeding process, addressing stress and social functioning), and often requires a multidisciplinary approach.
