Vitamin A has been shown to be important in immunity and in differentiation of epithelial tissues. Serum concentrations of vitamin A (retinol) were measured at birth, in 54 preterm and 24 full term infants. Vitamin A concentrations were significantly lower in the preterm compared to the full term infants (9.81 +/- 0.58 micrograms/dl v. 15.58 +/- 1.00 micrograms/dl, P = 0.0001). Serum retinol and birth weight were positively correlated (r = 0.39, P = 0.0004); however, there was no correlation between maternal and infant vitamin A concentrations. The initially reduced vitamin A levels in the preterm infants were not associated with respiratory distress syndrome or pneumonia.
维生素A已被证明在免疫和上皮组织分化中起重要作用。对54名早产儿和24名足月儿出生时的血清维生素A（视黄醇）浓度进行了测量。与足月儿相比，早产儿的维生素A浓度显著降低（9.81±0.58微克/分升对15.58±1.00微克/分升，P = 0.0001）。血清视黄醇与出生体重呈正相关（r = 0.39，P = 0.0004）；然而，母婴维生素A浓度之间没有相关性。早产儿最初降低的维生素A水平与呼吸窘迫综合征或肺炎无关。
