Incidence of sleep disorders in children with presumed normal variant short stature.

Objective: To determine whether unrecognized obstructive sleep apnoea (OSA) is present in some children diagnosed with normal variant short stature.

Methods: One hundred and fifty-eight children aged less than 15 years and previously diagnosed with familial short stature or constitutional delay of growth were identified from the endocrine clinic database. A validated, standardized questionnaire designed to screen for symptoms of sleep disorders in children was mailed to the parents of eligible children.
