Abstract

The cord blood of 50 normal-birth-weight neonates (more than 2,500 grams) and 50 low-birth-weight neonates (less than 2,500 grams) and the respective mother's blood were analyzed for folate, vitamin B6, riboflavin, nicotinate, pantothenate, thiamin, biotin, vitamin B12, vitamin A, and beta-carotene concentrations at parturition. No mothers had received supplemental vitamin intake. Except for vitamin A and beta-carotene, maternal vitamin levels were lower than those of neonates in all instances. Vitamin levels in the blood of low-birth-weight neonates were the same of those of normal-birth-weight infants except for significantly lower folate, vitamin B12, and pantothenate levels.

摘要

对50例正常出生体重新生儿（超过2500克）和50例低出生体重新生儿（低于2500克）的脐带血及其各自母亲的血液进行分析，以测定分娩时叶酸、维生素B6、核黄素、烟酸、泛酸、硫胺素、生物素、维生素B12、维生素A和β-胡萝卜素的浓度。没有母亲接受过维生素补充剂。除维生素A和β-胡萝卜素外，所有情况下母亲的维生素水平均低于新生儿。低出生体重新生儿血液中的维生素水平与正常出生体重婴儿相同，只是叶酸、维生素B12和泛酸水平显著较低。
