Four studies examined impacts of iron supplementation on school children of various ages and both sexes. The first study investigated impact of iron-folic acid supplements for 60 d on cognition in 94 boys and girls aged 5-8 y. Improvement in total scores of the anemics was significantly higher than the nonanemics in 7-8-y-old children only. The second study assessed impacts of supplementation on cognition in 14 pairs of 5-6-y-old anemic boys, with clear beneficial effects on cognitive function. The third study investigated effects of varying dosages of elemental iron on cognitive function in 48 boys aged 8-15 y, with different levels of improvement. The fourth study investigated impacts of iron supplementation on 163 anemic girls aged 8-15 y with treatment and evaluations at 4 and 8 mo, with significantly improved scores in cognitive function after the eighth month.
四项研究考察了铁补充剂对不同年龄和性别的学童的影响。第一项研究调查了铁叶酸补充剂60天对94名5至8岁男孩和女孩认知能力的影响。仅在7至8岁儿童中，贫血儿童的总分改善显著高于非贫血儿童。第二项研究评估了补充剂对14对5至6岁贫血男孩认知能力的影响，对认知功能有明显的有益作用。第三项研究调查了不同剂量的元素铁对48名8至15岁男孩认知功能的影响，改善程度不同。第四项研究调查了铁补充剂对163名8至15岁贫血女孩的影响，在4个月和8个月时进行治疗和评估，第八个月后认知功能得分显著提高。
