铁缺乏症对婴幼儿智能发育的影响

The Influence of Iron Deficiency Dysfunction on Infant's Intellectual Development

为分析铁缺乏症(IDD)对婴幼儿智能发育的影响,随机抽取了6个月至3岁婴幼儿200例,按有否铁缺乏分组,比较了其与智能的关系。结果表明,铁缺乏症检出率为17.5％,铁缺乏组婴幼儿智能发育商(DQ)明显下降,与正常组比较差异有显著性,铁缺乏程度越重,DQ值越低。可见铁缺乏症对婴幼儿大脑发育造成不良影响,对该症无贫血阶段及轻度缺铁性贫血期(IDA)应予重视。

To analyze the influence of iron deficiency dysfunction (IDD) on infant' s intellectual development, 200 children between 6 months to 3 years old were randomly collected and divided into iron deficiency group and normal group. Intellectual development was compared between two groups. The result showed that the incidence of iron deficiency dysfunction was 17.5% . Intellectual development quotient (DQ) in iron deficiency group was significantly lower than that in normal group. And the more severe the degree of the iron deficiency was, the lower DQ was. It concludes iron deficiency dysfunction takes adverse effect on infant' s intellectual development. Hence, it should attach importance to iron deficiency dysfunction without anemia and mild iron deficiency anemia (IDA) .
