目的探讨轻度缺铁性贫血 (IDA)对 12～ 13岁初中新生学习和运动能力的影响。方法选择 12～ 13岁初中新生 ,血红蛋白 (Hb) <12 0 g/ L和 >12 0 g/ L的各 30人为实验组和对照组 ,每人每日实验组口服硫酸亚铁 30 0 mg,Vit C5 0 m g;对照组口服淀粉片 30 0 mg,Vit C 5 0 m g ,共 5 0天 ,测定两组用药前后 Hb、心率、学习能力和运动能力的变化 ,并进行显著性差异的比较。结果测定值表明 ,两组比较 ,用药前有显著性差异 ;用药后无显著性差异。结论尽管是轻度的 IDA,对 12～ 13岁初中生的学习和运动能力都有明显的影响。适当的饮食、补充铁剂和 Vit C可迅速纠正贫血 ,并使学习和运动能力恢复正常。
Objective To investigate the effects of mild iron deficiency anemia (IDA) on learning and locomotor ability of 12-13-year-old middle school freshmen. Methods Thirty newborns, 12 to 13 years old, 30 children with hemoglobin (Hb) <12 0 g / L and> 120 g / L, were selected as the experimental group and the control group. Vit C 0 0 mg and control group were given orally 30 mg of starch and 50 mg of Vit C for 50 days respectively. The changes of Hb, heart rate, learning ability and motor ability of the two groups before and after treatment were measured, and the significant differences were compared. The results show that the two groups were significantly different before treatment; no significant difference after treatment. Conclusions Although mild IDA has a significant effect on learning and motor ability among 12-13-year-old middle school students. Appropriate diet, iron supplementation and Vit C can quickly correct anemia and normalize learning and exercise skills.
