Abstract: Objective To understand the serum vitamin A, iron, and zinc status of infants aged 0~18 months in rural arear of Shaanxi province, and the relation with Hb. Method Hb and serum vitamin A, iron, zinc were detected in 336 infants, and the content of which were compared between the anemic children and the normal children. Results The deficiency rate of serum vitamin A, iron, and zinc were 67.27%, 29.1% and 90.9%, respectively.The average content of serum vitamin A, iron, and zinc in anemic group (0.54 μmol/L, 881.21 μg/L, 610.01 μg/L) were lower than those of control group(0.81 μmol/L, 1 227.93 μg/L, 679.40 μg/L), and there were statistical significance (P<0.05). Conclusion The deficiency of serum vitamin A, iron, and zinc are serious in rural area of Shaanxi province.The contents of serum iron and zinc are positively associated with hemoglobin concentration.

摘要： 目的 了解陕西部分农村地区0~18月龄婴幼儿血清维生素A、铁、锌状况, 探讨其与血红蛋白含量的关系。方法 采取随机整群抽样的方法对陕西澄城县和富平县农村336名出生至18个月婴幼儿, 检测其血清维生素A、铁、锌状况和血红蛋白含量, 并对贫血与非贫血儿童血清中三种微量元素进行比较。结果 336名0~18个月婴幼儿贫血118例, 贫血检出率为35.12%, 血清维生素A、铁、锌缺乏率分别为67.27%、29.1%和90.9%;贫血组血清VitA、铁、锌的平均含量(0.54 μmol/L、881.21 μg/L, 610.01 μg/L)明显低于非贫血组(0.81 μmol/L、1 227.93 μg/L, 679.40 μg/L), 且差异有统计学意义(P<0.05)。结论 陕西农村地区0~18月龄婴幼儿血清维生素A、Fe、Zn缺乏现象较为普遍, 贫血儿童血清维生素A、铁、锌含量显著低于非贫血儿童, 有显著相关性。
