摘　　要：观察乙二胺四乙酸铁钠（NaFeEDTA）强化酱油干预对铁缺乏不贫血（iron deficiency without anemia,IDNA）学生注意力和学习成绩的影响。以血红蛋白（Hb）值、血清铁蛋白（SF）值为指标将受试者分成正常（NA）组、铁缺乏不贫血（IDNA）组,观察NaFeEDTA强化酱油对IDNA、注意力和学习成绩的效果。结果表明：IDNA组学生的注意力总得分、注意分配、注意稳定性和语文、数学成绩显著低于正常组学生（P〈0.01~P〈0.05）;NaFeEDTA强化酱油干预后,IDNA学生的注意力总得分、注意分配、注意稳定性显著改善（P〈0.01）,语文、数学成绩显著提高（P〈0.01~P〈0.05）。试验结果提示,NaFeEDTA强化酱油对铁缺乏不贫血学生的铁营养状况、注意力和学习成绩有改善作用。The purpose of this study is to investigate the effect of iron deficient with anemia（IDNA） teenagers on attention ability and educational achievement.Subjects were divided into two groups according to their iron status and Hb value and given NaFeEDTA fortified soy sauce.The results showed attention ability,attention discrimination and attention stability of IDNA students were lower than normal iron students（P0.01~P0.05）,same as mathematic and Chinese language scores.Iron supplementation significantly improved attention ability,attention discrimination and attention stability of IDNA subjects（P0.01）.Iron supplementation also improved mathematic and Chinese language scores of IDNA subjects（P0.01~P0.05）.Our findings suggest that iron deficient even without anemia can impair attention ability and educational achievement which can be corrected with NaFeEDTA fortified soy sauce.
