Selenium status in term and preterm infants during the first months of life.

Objective: We hypothesized that very low birth weight (VLBW) infants have reduced serum and red blood cell (RBC) selenium (Se) at birth, which decrease further with current nutrition and are associated with chronic lung disease and septicaemia.

Design: We studied Se intake, concentration in serum and RBCs and glutathione peroxidase (GSH-Px) activity in preterm and term infants from birth until 16 weeks. Data are mean+/-standard deviation (s.
