The efficacy of a number of interventions that include fortified complementary foods (FCFs) or other products to improve infant and young child feeding (IYCF) is well established. Programs that provide such products free or at a subsidized price are implemented in many countries around the world. Demonstrating the impact at scale of these programs has been challenging, and rigorous information on coverage and utilization is lacking. The objective of this article is to review key findings from 11 coverage surveys of IYCF programs distributing or selling FCFs or micronutrient powders in 5 countries. Programs were implemented in Ghana, Cote d'Ivoire, India, Bangladesh, and Vietnam. Surveys were implemented at different stages of program implementation between 2013 and 2015. The Fortification Assessment Coverage Toolkit (FACT) was developed to assess 3 levels of coverage (message: awareness of the product; contact: use of the product ≥1 time; and effective: regular use aligned with program-specific goals), as well as barriers and factors that facilitate coverage. Analyses included the coverage estimates, as well as an assessment of equity of coverage between the poor and nonpoor, and between those with poor and adequate child feeding practices. Coverage varied greatly between countries and program models. Message coverage ranged from 29.0% to 99.7%, contact coverage from 22.6% to 94.4%, and effective coverage from 0.8% to 88.3%. Beyond creating awareness, programs that achieved high coverage were those with effective mechanisms in place to overcome barriers for both supply and demand. Variability in coverage was likely due to the program design, delivery model, quality of implementation, and product type. Measuring program coverage and understanding its determinants is essential for program improvement and to estimate the potential for impact of programs at scale. Use of the FACT can help overcome this evidence gap.
许多包括强化辅食(FCFs)或其他产品在内的干预措施在改善婴幼儿喂养(IYCF)方面的功效已得到充分证实。世界上许多国家都实施了免费或以补贴价格提供此类产品的项目。证明这些项目在大规模实施时的影响颇具挑战性,并且缺乏关于覆盖范围和使用情况的严格信息。本文的目的是回顾在5个国家开展的11项关于分发或销售FCFs或微量营养素粉的IYCF项目覆盖情况调查的主要结果。这些项目在加纳、科特迪瓦、印度、孟加拉国和越南实施。调查在2013年至2015年项目实施的不同阶段进行。强化评估覆盖工具包(FACT)旨在评估3个覆盖层面(信息:对产品的认知;接触:产品使用≥1次;有效:与项目特定目标一致的定期使用)以及促进覆盖的障碍和因素。分析包括覆盖范围估计,以及对贫困和非贫困人群之间、儿童喂养习惯良好和不佳人群之间覆盖公平性的评估。各国和项目模式之间的覆盖情况差异很大。信息覆盖范围从29.0%到99.7%,接触覆盖范围从22.6%到94.4%,有效覆盖范围从0.8%到88.3%。除了提高认知度之外,实现高覆盖率的项目是那些具备有效机制以克服供需双方障碍的项目。覆盖范围的差异可能归因于项目设计、交付模式、实施质量和产品类型。衡量项目覆盖范围并了解其决定因素对于项目改进以及估计大规模项目的潜在影响至关重要。使用FACT有助于填补这一证据空白。
