Aim: To evaluate selenium (Se) and copper (Cu) concentrations in Greek and Albanian immigrant mothers and in the cord blood of their newborns.
Subjects and methods: From 1118 Greek and 820 Albanian mothers and from the cord blood of their neonates blood was obtained for Se and Cu measurement. Se and Cu concentrations were determined in sera with graphite furnace atomic absorption spectroscopy (GFAAAS) and atomic absorption spectrometry, respectively. In all, 30 days' nutrient intakes were evaluated in both groups.
Results: Animal protein, Se and Cu intakes were poor in the Albanians vs the Greeks (P<0.001). Se concentrations in the Greek mothers (68.3plusminus8.5 mug/l) and in their newborns (37.02plusminus8.9 mug/l) were found higher as compared with those in Albanian mothers (37.4plusminus9.9 mug/l) and in their newborns (34.3plusminus9.1 mug/l) (P<0.001). Cu levels were also found higher (P<0.001) in the Greek mothers (1687plusminus353 mug/l) and in their neonates (449plusminus87 mug/l) compared with those in the Albanian mothers (959plusminus318 mug/l) and in their newborns (229plusminus67 mug/l). Additionally, 31.5% of neonates born to Albanian women with Se concentrations less than 28 mug/l had higher Se levels (P<0.01) than their mothers.
Conclusions: The low Se and Cu levels evaluated in the Albanian mothers and their newborns could be related to their poor animal protein intake which could be the consequence of their low socioeconomic status. As an effective preventive measure, accurate dietetic strategies to assess the requirements of pregnant immigrant women for trace elements may be planned in Greece.
