Abstract

Vitamin A status was determined in infants born at term or prematurely to assess if vitamin A levels at birth were related to gestational age. Vitamin A levels were measured in cord blood samples from 13 infants born at term and in blood samples obtained within two hours of birth in 26 preterm infants (median gestational age 31 weeks, range 27-35). None of the preterm infants developed chronic lung disease. The vitamin A levels of the term infants (median 0.71 mumol/l, range 0.34 to 1.27) were significantly higher than those of infants born preterm (median 0.35 mumol/l, range 0.12 to 1.22), p < 0.01. Vitamin A levels correlated significantly with gestational age (vitamin A level = 0.024 gestational age (weeks) -0.23, r = 0.39, p < 0.02. We thus conclude that gestational age must be taken into account when interpreting vitamin A levels.

摘要

测定足月儿或早产儿的维生素A状况，以评估出生时的维生素A水平是否与胎龄有关。对13名足月儿的脐带血样本以及26名早产儿（中位胎龄31周，范围27 - 35周）出生后两小时内采集的血样进行了维生素A水平测定。没有早产儿患慢性肺病。足月儿的维生素A水平（中位值0.71μmol/l，范围0.34至1.27）显著高于早产儿（中位值0.35μmol/l，范围0.12至1.22），p<0.01。维生素A水平与胎龄显著相关（维生素A水平 = 0.024×胎龄（周）- 0.23，r = 0.39，p<0.02）。因此，我们得出结论，在解释维生素A水平时必须考虑胎龄。
