The plasma concentrations of vitamin A, vitamin E, beta-carotene and serum concentrations of zinc, retinol-binding protein and prealbumin were examined for a random cluster sample, stratified by socioeconomic status, of 467 healthy preschool children. Children were aged 9-62 months; 44% were females. The mean plasma values were: vitamin A, 1.29 micromol l(-1); vitamin E, 18.9 micromol l(-1); and beta-carotene, 0.30 micromol l(-1). The mean serum values were: zinc, 13.9 micromol l(-1); retinol-binding protein, 25.5 mg l(-1); and prealbumin, 186.2 mg l(-1). The mean molar ratio of vitamin A to retinol-binding protein for the study group was 1.10. There were no differences in the mean values of any of the measured micronutrients between the genders. The results of this survey do not indicate that the prevalence of micronutrient deficiency in this preschool population is of public health significance.
对467名健康学龄前儿童的随机整群样本进行了检测，该样本按社会经济地位分层，检测了血浆中维生素A、维生素E、β-胡萝卜素的浓度以及血清中锌、视黄醇结合蛋白和前白蛋白的浓度。儿童年龄在9至62个月之间；44%为女性。血浆平均值为：维生素A，1.29微摩尔/升；维生素E，18.9微摩尔/升；β-胡萝卜素，0.30微摩尔/升。血清平均值为：锌，13.9微摩尔/升；视黄醇结合蛋白，25.5毫克/升；前白蛋白，186.2毫克/升。研究组维生素A与视黄醇结合蛋白的平均摩尔比为1.10。各性别间任何一种被测微量营养素的平均值均无差异。本次调查结果表明，该学龄前人群中微量营养素缺乏的患病率无公共卫生意义。
