Serum vitamin C, vitamin A and carotene concentrations were measured in 425, 256 and 256 infants aged between 3 weeks and 12 months. Vitamin C concentrations were in general satisfactory, whereas vitamin A and especially carotene concentrations were unacceptably low in a large number of infants. concentrations were not correlated with age and sex nor with breast-feeding, but low and very low concentrations were more common after 6 months. Although clinical manifestations of the vitamin deficiencies were not present, the evidence points to an increased health risk for children.
对425名、256名和256名年龄在3周龄至12月龄之间的婴儿测量了血清维生素C、维生素A和胡萝卜素浓度。维生素C浓度总体上令人满意，而大量婴儿的维生素A尤其是胡萝卜素浓度低至不可接受的程度。这些浓度与年龄、性别以及母乳喂养均无关联，但低浓度和极低浓度在6个月龄后更为常见。尽管未出现维生素缺乏的临床表现，但有证据表明儿童的健康风险增加。
