Abstract: 【Objective】 To explore the effects of iron deficiency anemia(IDA) on mental devenlopment of infants. 【Methods】 42 infants coincided with IDA diagnosis were selected as test group, and normal 42 infants with equal background were selected as control group. The Gesell Development Diagosis Schedule was used to evaluate children's mental development. 【Results】 Both adaptive behavior and fine motor DQ were lower in test group than in control group, the difference was significant(P<0.05). There were positively correlations between the hemoglobin level and adaptive behavior or fine motor, the correlation coefficients were respectively as 0.56 and 0.38(P<0.05). Hemoglobin level was the independent risk factor, which could affect chidren's adaptive behavior and fine motor development,the partial regression coefficient were 0.385 and 0.261(P<0.05)respectively. 【Conclusion】 IDA can affect adaptive behavior and fine motor development of infants.

摘要： 【目的】 探讨缺铁性贫血对婴幼儿智能发育的影响,为临床治疗提供参考依据。 【方法】 选取42名符合缺铁性贫血诊断标准的婴幼儿为病例组,背景资料相似的无缺铁性贫血病史的42名健康婴幼儿为对照组,使用盖塞尔发展诊断量表评估两组婴幼儿智能发育情况。 【结果】 病例组的适应行为、精细运动DQ值低于对照组,差异有统计学意义(P<0.05);血红蛋白水平与适应行为、精细运动DQ值存在正相关关系,其相关系数分别为0.56和0.38(P均<0.05);血红蛋白水平是适应行为、精细动作发育的独立危险因素,偏回归系数分别为0.385和0.261(P均<0.05)。 【结论】 缺铁性贫血可影响婴幼儿适应行为、精细动作的发育。
