目的了解非贫血铁缺乏症和缺铁性贫血婴幼儿的认知水平,为进一步治疗提供科学依据。方法采用Gesell发育测试法评估非贫血铁缺乏症和缺铁性贫血婴幼儿适应性、大运动、精细动作、语言和个人社交5个能区发育水平。结果患铁缺乏症的男婴较女婴更多(χ2=13.06,P=0.001),非贫血铁缺乏症(non-anemia iron deficiency,NAID)组、缺铁性贫血(iron deficiency anemia,IDA)组较铁充足(iron sufficiency,IS)组婴幼儿的5个能区发育水平落后(F适应性=13.64;F大运动=6.24;F精细动作=6.25;F语言=4.89;F个人社交=9.14,P值均<0.01),NAID和IDA婴幼儿之间差异无统计学意义;但男性婴幼儿在语言和个人社交发育商分数较女婴更低(F=9.299,P=0.003;F=4.250,P=0.042)。结论铁缺乏症伴或不伴贫血对婴幼儿的认知水平都有影响,提示在临床工作中应早期干预铁缺乏。
Objective To understand the cognition of non-anemia iron deficiency and iron deficiency anemia in infants and young children, and to provide a scientific basis for further treatment. Methods The Gesell developmental test was used to assess the developmental level of five areas of energy for non-anemic iron deficiency and iron-deficiency anemia in infants and young children, large exercise, meticulous motor activity, verbal and individual social. As a result, there were more baby boys with iron deficiency than girls (χ2 = 13.06, P = 0.001), non-anemia iron deficiency (NAID), iron deficiency anemia (IDA) The five energy regions of infants in the group with iron sufficiency (IS) developed less well (F fitness = 13.64; F grand movement = 6.24; F fine movement = 6.25; F language = 4.89; F personal social = 9.14 , P <0.01). There was no significant difference between NAID and IDA infants. However, the score of social infants in infants and young children was lower than that of female infants in language and individual (F = 9.299, P = 0.003; F = 4.250 , P = 0.042). Conclusion Iron deficiency with or without anemia has an impact on the cognitive level of infants and young children, suggesting that early intervention in the clinical work of iron deficiency.
