For comparison purposes vitamin E status was also determined in six term infants over the first 8 d following birth and in a group of thirteen adult volunteers. Vitamin E intakes in term and preterm infants were calculated from recorded food intakes and blood transfusions. In term infants plasma vitamin E concentration rose from 1.9 mg\/l (day 1) to 8 2 mg\/l by day 8. In comparison preterm plasma vitamin E concentration, 0.3 mg\/l (day I), did not change appreciably by day 8 (0.7mg\/l). Likewise RBC vitamin E concentration increased in term infants from 1.3 mg\/l (day 1) to 2.7 mg\/l (day 8), while in preterm infants it remained unchanged, 1.5 mg\/l (day 1) v. 1.3 mg\/l (day 8). Over the 3 weeks following birth, RBC vitamin E concentrations in the premature infants increased to adult values, while plasma vitamin E concentration did not reach the adult range until 8 weeks post-term. These slow changes in plasma vitamin E status occurred even though the vitamin E intake of these infants was similar to that proving adequate for term infants.<\/jats:p>","DOI":"10.1079\/bjn19900149","type":"journal-article","created":{"date-parts":[[2005,9,17]],"date-time":"2005-09-17T04:07:20Z","timestamp":1126930040000},"page":"631-638","source":"Crossref","is-referenced-by-count":59,"title":["Time
