School feeding programs can support children's nutrition, health, and education in emergencies. This study assessed the feasibility, trade-offs, cost efficiency, and perceived benefits of school feeding modalities operating in urban Yemen. It draws on primary data from a qualitative evaluation with 21 school feeding implementers and 88 beneficiaries conducted in Feb–Mar 2023, and secondary data from a desk review of published and program literature on school feeding operations. Results showed that school feeding provided students with on average 18%, 40%, and 66% of daily energy, protein, and micronutrient requirements, respectively. Models including fortified snacks were 3–11 times more cost-efficient in terms of nutrient delivery. The most prominent strength of the models examined were the perceived benefits on child, family, and financial outcomes. Among the main weaknesses was the poor nutritional quality of the meal, which in turn emerged as a primary opportunity to improve school feeding through hybrid models providing a combination of fortified snacks and healthy meals. Other weaknesses such as poor water, sanitation, and hygiene infrastructure, and desired improvements such as the school kitchen and canteen, require considerable investments. Hybrid models are cost-efficient, acceptable, and feasible in Yemen and can serve the diet and nutrition needs of school-aged children.

学校供餐改善受冲突影响地区儿童营养：也门替代模式的可行性和成本效益


学校供餐计划可以在紧急情况下支持儿童的营养、健康和教育。本研究评估了在也门城市运营的学校供餐方式的可行性、权衡、成本效益和感知收益。它借鉴了 2023 年 2 月至 3 月对 21 名学校供餐实施者和 88 名受益人进行的定性评估的主要数据，以及来自对学校供餐运营的已发表和计划文献的案头审查的次要数据。结果显示，学校供餐分别为学生提供了平均 18%、40% 和 66% 的每日能量、蛋白质和微量营养素需求。包括强化零食的模型在营养输送方面的成本效益高出 3-11 倍。所研究的模型最突出的优势是对儿童、家庭和财务结果的感知益处。主要弱点之一是膳食的营养质量差，这反过来又成为通过提供强化零食和健康膳食相结合的混合模式改善学校供餐的主要机会。其他弱点，如水、环境卫生和个人卫生基础设施差，以及学校厨房和食堂等需要改进的弱点，需要大量投资。混合模式在也门具有成本效益、可接受和可行性，可以满足学龄儿童的饮食和营养需求。
