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 explore an effective way to solve the problem of children’s vitamins and trace elements deficiency in our country, we used double-blind controlled study to treat 115 children and 103 children in two kindergartens respectively for two and a half months with vitamins and trace elements preparations. The results showed that the average height and weight gain of children taking vitamins and trace elements were significantly higher than that of placebo (P <0.01), and the mean hemoglobin concentration and serum zinc level were significantly increased (P <0.01). Tip on the basis of the daily diet on the amount of vitamin supplements and trace elements in children can promote children’s growth and development, improve children’s nutritional status of iron and zinc.
