Iron is an essential nutrient for normal growth and neurodevelopment of infants. Iron deficiency (ID) remains the most common micronutrient deficiency worldwide. There are convincing data that ID is associated with negative effects on neurological and psychomotor development.
In this review, we provide an overview of current knowledge of the importance of iron in normal term breast-fed infants with a focus on recommendations, metabolism, and iron requirements.
Health organizations around the world recommend the introduction of iron-rich foods or iron supplements for growing infants to prevent ID. However, there is no routine screening for ID in infancy. Multicenter trials with long-term follow-up are needed to investigate the association between iron fortification/supplementation and various health outcomes.
铁是婴儿正常生长和神经发育所必需的营养素。缺铁仍然是全球最常见的微量营养素缺乏症。有确凿的数据表明,缺铁与对神经和精神运动发育的负面影响有关。
在本综述中,我们概述了铁在足月母乳喂养婴儿中的重要性的当前知识,重点是建议、代谢和铁需求。
世界各地的卫生组织建议为成长中的婴儿引入富含铁的食物或铁补充剂以预防缺铁。然而,婴儿期没有对缺铁进行常规筛查。需要进行长期随访的多中心试验来研究铁强化/补充与各种健康结果之间的关联。
