Around one-quarter of the world's children suffer from iron deficiency anemia, and many of them live in malaria-endemic areas. However, there is evidence that iron supplements can increase risk of severe malaria morbidity. The dilemma is how to move forward with interventions to prevent iron deficiency and its consequences in young children, using strategies that minimize risks of malaria and related infections. Screening for iron deficiency is problematic for several reasons. Two complementary strategies are suggested for moving forward with interventions to prevent iron deficiency in children exposed to malaria. The first is to reduce exposure to iron in the form of supplements by: adopting a lifecycle approach to pediatric iron deficiency beginning in utero, using the lowest adequate dose, and giving iron in or with foods. The second is to coordinate iron interventions with malaria control efforts. To stop all iron interventions in malaria-endemic areas is an unreasonable policy option. While research findings continue to increase our understanding, there are also programmatic ways forward with the knowledge at hand.
全世界约有四分之一的儿童患有缺铁性贫血,其中许多儿童生活在疟疾流行地区。然而,有证据表明,铁补充剂会增加严重疟疾发病率的风险。问题是如何在采取干预措施预防儿童缺铁及其后果方面取得进展,这些措施应尽量减少疟疾和相关感染的风险。由于多种原因,对缺铁进行筛查存在问题。针对这一问题,提出了两种互补的策略来推进针对疟疾环境中儿童缺铁的干预措施。第一种策略是通过以下方法减少补充形式的铁暴露:从胎儿期开始采用生命周期方法来预防儿童缺铁、使用最低足够剂量以及在食物中或与食物一起补充铁。第二种策略是将铁干预措施与疟疾控制工作协调起来。在疟疾流行地区停止所有铁干预措施是一种不合理的政策选择。虽然研究结果不断加深我们对缺铁性贫血的认识,但我们也可以根据现有知识制定相应的计划。
