Abstract：To determine the relationship between Zinc concentration and prenatal growth，66 newborns were divided into small for gestational age（SGA）group and appropriate for gestationa age（AGA）group according to their birthweight and gestational ages．The serum Zinc concentration，insulin-like growth factor-1（IGF-1）and insulin-like growth factor binding protein-3（IGFBP-3）levels in cord blood of newborms were measured by atomic absorption spectroscopy，radioimmunoassay（RIA）and immunoradioassays（IRMA）respectively．Results showed that the concentration of Zinc and the levels of IGF-1，IGFBP-3 were significantly lower in SGA group than those in AGA group（P＜0．01，respectively）．This suggests that the fetal growth correlates closely with Zinc concentration．Lacking of Zinc can result in intrauterine growth retardation．Zinc supplement is necessary for mother during pregnancy．
