欧洲:缺铁儿童知多少

目前对体内铁的研究多集中于铁缺乏;对于缺铁性贫血、铁过量等情况还缺少关注。
青少年儿童是最容易发生铁过量或者缺乏的群体;基于此在欧洲健康的幼龄儿童中进行了相关的调查。
通过饮食摄入计算缺铁情况和铁摄入,发现缺铁与经济状况和奶制品类型有关。
即便在健康的儿童中,缺铁也是普遍的,且铁摄入量低于推荐指标;12月龄以上儿童患病率更高。
西欧和北欧的情形优于东欧;约3/4的西欧儿童铁充足。

Iron deficiency (ID) is common in young children aged 6-36 mo. Although the hazards associated with iron deficiency anemia (IDA) are well known, concerns about risks associated with excess iron intake in young children are emerging. To characterize iron status in Europe, we describe the prevalence of ID, IDA, iron repletion, and excess stores with the use of published data from a systematic review on iron intake and deficiency rates, combined with other selected iron status data in young European children. Various definitions for ID and IDA were applied across studies. ID prevalence varied depending on socioeconomic status and type of milk fed (i.e., human or cow milk or formula). Without regard to these factors, ID was reported in 3-48% of children aged ≥12 mo across the countries. For 6- to 12-mo-old infants, based on studies that did not differentiate these factors, ID prevalence was 4-18%. IDA was <5% in most studies in Northern and Western Europe but was considerably higher in Eastern Europe (9-50%). According to current iron status data from a sample of healthy Western European children aged 12-36 mo, 69% were iron replete, and the 97.5th percentile for serum ferritin (SF) was 64.3 μg/L. In another sample, 79% of 24-mo-old children were iron replete, and the 97.5th percentile for SF was 57.3 μg/L. Average iron intake in most countries studied was close to or below the UK's Recommended Dietary Allowance. In conclusion, even in healthy European children aged 6-36 mo, ID is still common. In Western European populations for whom data were available, approximately three-quarters of children were found to be iron replete, and excess iron stores (SF >100 μg/L) did not appear to be a concern. Consensus on the definitions of iron repletion and excess stores, as well as on ID and IDA, is needed.
