  • Title: Hormonal status of short children born small for gestational age.
    Author: Boguszewski M, Bjarnason R, Jansson C, Rosberg S, Albertsson-Wikland K.
    Journal: Acta Paediatr Suppl; 1997 Nov; 423():189-92. PubMed ID: 9401570.
    Abstract:
    The present study was undertaken to evaluate the hormonal status in a subgroup of prepubertal children born small for gestational age (SGA) who lacked postnatal catch-up growth. In this subgroup, a reduced rate of growth hormone (GH) secretion was found, compared with reference groups of healthy children born appropriate for gestational age, of either normal or short stature at the time of investigation. In addition, an abnormal pattern of GH secretion was observed in short children born SGA, which was most pronounced in the younger children, and involved an increased frequency of GH peaks of low amplitude, combined with increased baseline secretion. Levels of insulin-like growth factor I (IGF-I) and IGF-binding protein-3 were also reduced in short children born SGA, compared with the reference groups. These findings may explain, in part, the lack of postnatal catch-up growth in short children born SGA.
