[IGF-I sensitivity in small for gestational age children].

Background: The lack of catch up growth (CUG) in small for gestational age (SGA) children may be related to a reduced sensitivity to insulin growth factor 1 (IGF-I).

Aim: To assess the sensitivity to IGF-I in small for gestational age children, measuring basal and post IGF-I nocturnal profile of growth hormone (GH).

Patients And Methods: We studied 34 prepubertal SGA children aged 4 to 11 years.
