营养性贫血和锌缺乏,在儿童中的检出率都较高。食物中铁与锌的含量又往往呈正比关系,而且两者都富含于高蛋白食品之中。因此可以提出一个假设:儿童营养性贫血与儿童缺锌,可能存在着伴随、相关甚至因果关系。为了搞清这个问题,我们对7～12岁小学生营养性贫血和缺锌之间的关系作了初步调查分析。1.调查对象:造沈阳市区三所有代表性的铁路小学,随机抽取7～12岁小学生563名进行营养性贫血调查,并在其中随机抽取267名进行发锌含量测定。2.贫血判定:同时进行血红蛋白(Hb)
Nutritional anemia and zinc deficiency are high in children. Iron and zinc in food are often in direct proportion, and both are rich in high-protein foods. Therefore, we can make a hypothesis: There may be accompanying, related or even causal relationships between children’s nutritional anemia and zinc deficiency in children. In order to clarify this issue, we conducted a preliminary investigation and analysis of the relationship between nutritional anemia and zinc deficiency among pupils aged 7-12 years. 1. Survey respondents: Three representative railroad primary schools in Shenyang were selected. 563 primary school students from 7 to 12 years old were randomly selected to conduct nutritional anemia investigation. A total of 267 zinc content was determined in the railway primary schools. 2. Anemia judgment: simultaneous hemoglobin (Hb)
