摘要
为探讨解决我国儿童维生素和微量元素缺乏问题的有效途径,本文采用双盲对照研究法,在两所幼儿园115名和103名儿童分别服用维生素及微量元素制剂和安慰剂两个半月。结果表明:服用维生素及微量元素儿童较服安慰剂儿童平均身高和体重增长非常显著(P<0.01),平均血红蛋白浓度和血清锌水平有显著提高(P<0.01)。提示在日常饮食基础上对儿童适量补充维生素及微量元素可促进儿童生长发育,改善儿童铁和锌的营养状况。
In order to study an effective way of solving the problem of vitamine and trace element deficiency in children. Vitamines and trace elements and a placebo were given to 115 and 103 children in two kindergartens for two and a half months respectively, using double blind control study method. Results show that the mean height and weight of children taking vitamines and trace elements increase more notably than that of children taking placebo ( P <0. 01), and so does mean hemoglobin and serum zinc concentration (P <0. 01), It means that the appropriate supplementation of vitamines and trace elements besides normal diet can promote the growth and development of children improve iron and zinc nutrition status of children.
