营养不良(发育迟缓和消瘦)的挑战仍然是非洲5岁以下儿童的主要健康问题，非洲大陆占全球所有发育迟缓儿童的三分之一以上，占全球所有消瘦儿童的四分之一以上。尽管越来越多的证据表明农业干预在改善营养方面的作用，但在非洲，关于牲畜干预对营养的影响的经验证据很少。这项审查旨在确定牲畜干预措施在减少非洲五岁以下儿童以及孕妇和哺乳期妇女营养不良方面是否有效。审查将根据PRISMA指导方针进行。将搜索主要的电子数据库，并补充来自谷歌和谷歌学者的灰色和非索引文献，以及其他文章和报告的专家咨询。在采用包括网格、布尔搜索运算符和截断/通配符符号在内的搜索策略时，将使用Pico标准来缩小或扩大搜索范围。在非洲进行的关于牲畜干预对孕产妇和儿童营养的影响的文章，如果符合既定的纳入标准，将在经过两名独立审查者的严格评估后纳入审查。将使用标准化表格从纳入的研究中提取数据。提取的数据将进行定性和定量的总结和综合，并提出关键成果。系统审查和荟萃分析产生的证据对于指导对营养敏感的牲畜干预措施和有关营养规划的政策，特别是指导如何利用牲畜干预措施减轻营养不良的负担具有重要意义。
The challenge of undernutrition (stunting and wasting) still remains a major health concern in children below 5 years of age in Africa, with the continent accounting for more than one third of all stunted children and more than one quarter of all wasted children globally. Despite the growing evidence on the role of agriculture interventions in improving nutrition, empirical evidence on the impact of livestock intervention on nutrition in Africa is scant. This review is aimed at determining whether livestock interventions are effective in reducing undernutrition in children below five years of age and in pregnant and lactating women in Africa. The review will be conducted according to PRISMA guidelines. Major electronic databases will be searched and complemented with grey and non-indexed literature from google and google scholar, and expert consultation for additional articles and reports. PICO criteria will be used while employing search strategies including MeSH, Boolean search operators and truncation/wildcard symbol to narrow or broaden the search. Articles on effect of livestock interventions on maternal and child nutrition conducted in Africa that meet the set inclusion criteria will be included in the review after critical appraisal by two independent reviewers. A standardized form will be used to extract data from included studies. The extracted data will be summarized and synthesized both qualitatively and quantitatively and key outcomes presented. Evidence generated from the systematic review and meta-analysis will be important for guiding nutrition sensitive livestock interventions and policies on nutrition programming, specifically on how to leverage on livestock interventions to reduce the burden of undernutrition.
