The burden of anemia in Indian children, based on capillary blood sampling, is believed to be profound and worsening (67.1%) according to the successive National Family Health Surveys (NFHS). This might be an overestimate. The recent Comprehensive National Nutrition Survey of Indian children, that used venous blood sampling, found only less than half (30.7%) the NFHS prevalence, of which only one third was due to iron deficiency (ID). Unfortunately, the apparently worsening NFHS anemia burden estimate has been interpreted as an inadequacy of the present iron supplementation policy. This has led to additional iron supply through mandatory rice fortification. However, the lack of efficacy of iron supplementation appears inevitable, if the true prevalence of iron deficiency anemia is only about 10%. Thus, etiology is a critical consideration when devising appropriate and effective prevention policies. Future policies must focus on precision, thoughtfulness, restraint, and community engagement.
根据连续的国家家庭健康调查(NFHS),基于毛细血管血样采集,印度儿童的贫血负担据信非常严重且正在恶化(67.1%)。这可能是一个高估。最近的印度儿童综合国家营养调查使用静脉血样采集,发现只有不到一半(30.7%)的 NFHS 患病率,其中只有三分之一是由于缺铁(ID)。不幸的是,贫血负担估计值似乎在恶化,被解释为目前铁补充政策的不足。这导致通过强制大米强化来提供额外的铁供应。然而,如果缺铁性贫血的真实患病率仅约为 10%,那么铁补充的效果缺乏是不可避免的。因此,在制定适当和有效的预防政策时,病因是一个关键的考虑因素。未来的政策必须注重精准性、深思熟虑、克制和社区参与。
