摘要
目的：以观察锌干预对学龄前儿童膳食铁吸收的影响。方法：实施分为９４年春、秋和９５年春、秋四次进行。５２０名６～７岁儿童（城乡各半，男女各半）分为四组：单纯补锌组、锌加复合微量元素组、单纯复合微量元素组和对照组。实验期为１０周，受试儿童均摄入正常膳食。结果：复合微量元素明显有利于促进膳食铁吸收（Ｐ＜０．０５）。结论：在选择各种微量元素强化食品时，根据个人实际情况，并注意营养素的均衡补充，才能防治微量营养素缺乏病的发生。
Objective:To determine effects of zinc intervention on the absorption of dietary iron.Methods:520 pre school children aged 6 to 7 years(equal numbers of boys and girls),who were divided randomly into 4 groups:zinc supplement group,zinc plus micronutrient supplement group,micronutrient supplement group and control group.The experiment lasted for 10 weeks.Before and after zinc and micronutrients supplemented,blood samples were analyzed for haemoglobin(HB).Results:The observations showed that the concentration of HB in micronutrient supplement group is significantly higher than the others( P<0 05 ),the absorption of dietary iron is affected apparently by micronutrients.Conclusion:Attention should be paid to the supplementation of other nutrients before choosing some micronutrients be supplied of dietary for child.
