TRACE-ELEMENT CONTENT IN HUMAN-MILK DURING LACTATION OF PRETERM NEWBORNS

The present study has been finalized to perform the content of Zn, Cu, Cr, Se, Mn, F, Mo, Ni, and B in the preterm human milk over 21 d of l actation. Trace element (TE) contents were analyzed by inductively cou pled plasma atomic emission spectroscopy (ICP-MS), and median concentr ations of Zn, Cu, Cr, Se, Mn, and F observed in preterm milk did not d emonstrate significant differences in comparison to levels shown in te rm milk. A statistical significant difference (p < 0.05) has been foun d among Mo, Ni, and B content in preterm milk for every stage of lacta tion. TE content of infant blood founded concentrations of Mo in prete rm babies significantly (p < 0.01) lower than in term offsprings. Simi lar values of other TE content were obtained in blood of preterm and t erm newborns. These findings point to the need for a considerable reas sessment of the existing dietary recommendation for Mo content in infa nt feeding.
