Vitamin A status was assessed in a randomly selected group of neonates at delivery. A total of 105 neonates were included in the study. Cord vitamin A concentration was determined by high performance liquid chromatography (HPLC). Of 105 neonates, 53 (50.5 per cent) were males and 49 49.5 per cent) were females. The mean body weight of male neonates was slightly greater that that of female neonates (3271 +/- 575 vs. 3139 +/- 552 g). Mean cord plasma vitamin A level of the males was significantly lower (p < 0.05) than that of the female neonates (12.2 +/- 4.6 and 14.7 +/- 5.2 micrograms/100 ml respectively). The mean body weight of premature neonates (2186 +/- 530 g) was significantly lower (p < 0.05) compared with the mean body weight of full term neonates (3279 +/- 495 g). Cord plasma of preterm neonates had mean value of vitamin A significantly lower (p < 0.05) than full term neonates (8.3 +/- 3.2 vs 13.8 +/- 4.5 micrograms/100 ml). A trend of increasing birth weight with increasing cord plasma vitamin A level was evident.
在分娩时对一组随机挑选的新生儿进行了维生素A状况评估。共有105名新生儿纳入该研究。通过高效液相色谱法（HPLC）测定脐带血维生素A浓度。在105名新生儿中，53名（50.5%）为男性，49名（49.5%）为女性。男性新生儿的平均体重略高于女性新生儿（分别为3271±575克和3139±552克）。男性新生儿脐带血血浆维生素A水平显著低于女性新生儿（分别为12.2±4.6和14.7±5.2微克/100毫升，p<0.05）。早产新生儿的平均体重（2186±530克）显著低于足月新生儿的平均体重（3279±495克，p<0.05）。早产新生儿脐带血血浆维生素A的平均值显著低于足月新生儿（分别为8.3±3.2和13.8±4.5微克/100毫升，p<0.05）。随着脐带血血浆维生素A水平升高，出生体重增加的趋势明显。
