OBJECTIVE
This review aimed to (i) synthesise evidence of the impact of publicly procured school meals programmes on nutritional outcomes of children/adolescents (5-18 years) in sub-Saharan Africa and (ii) identify challenges and facilitators to implementing effective school meals programmes.
DESIGN
Mixed-methods systematic review ( 7 databases). Nutritional outcomes assessed were anthropometrics (underweight, stunting, wasting, overweight/obesity), micronutrient deficiencies, food consumed and food environment. Qualitative findings were coded using a nine-step school food system framework: and .
SETTING
Sub-Saharan Africa.
PARTICIPANTS
Children/adolescents (5-18 years), parents, school personnel and government officials.
RESULTS
Thirty-three studies (twenty-six qualitative, seven quantitative) from nine sub-Saharan African countries were included. Six studies found a positive impact of publicly procured school meals programmes on nutritional outcomes (wasting ( 1), stunting ( 3), underweight ( 1), vitamin A intake ( 1) and dietary diversity ( 1)). Fifty-three implementation challenges were identified, particularly during (e.g. training, payment), (e.g. meal quantity/quality/diversity, utensils) and (e.g. funding, monitoring, coordination). Implementation facilitators were identified ( 37) across (e.g. programme coordination), (e.g. food preferences, reduced stigma) and (e.g. engagement, positive perceptions). Included policy recommendations targeted , , and in nine, fifteen and twenty-five studies, respectively.
CONCLUSIONS
As many challenges remain, strengthening implementation (and therefore the nutritional impact) of school meals programmes in sub-Saharan Africa requires bold commitment and improved coordination at multiple levels of governance.
目的
本综述旨在:(i) 综合评估撒哈拉以南非洲地区公开采购学校供餐计划对儿童/青少年(5-18 岁)营养状况的影响;(ii) 确定实施有效学校供餐计划的挑战和促进因素。
设计
混合方法系统评价(7 个数据库)。评估的营养结果包括人体测量学指标(消瘦、发育迟缓、消瘦、超重/肥胖)、微量营养素缺乏、食物消耗和食物环境。定性结果使用九个步骤的学校食品系统框架进行编码:规划、采购、准备、供应、摄入、管理、监督、宣传和评估。
设置
撒哈拉以南非洲。
参与者
儿童/青少年(5-18 岁)、家长、学校人员和政府官员。
结果
来自九个撒哈拉以南非洲国家的 33 项研究(26 项定性研究,7 项定量研究)被纳入。六项研究发现公开采购学校供餐计划对营养结果有积极影响(消瘦(1)、发育迟缓(3)、消瘦(1)、维生素 A 摄入(1)和饮食多样性(1))。确定了 53 个实施挑战,特别是在规划(例如培训、付款)、采购(例如餐食数量/质量/多样性、餐具)和供应(例如餐食数量/质量/多样性、餐具)阶段。还确定了 37 个实施促进因素,涵盖规划(例如方案协调)、采购(例如食物偏好、减少污名化)和供应(例如参与、积极看法)等各个方面。纳入的政策建议分别针对规划、采购和供应三个方面,在九项、十五项和二十五项研究中有所涉及。
结论
鉴于仍然存在许多挑战,加强撒哈拉以南非洲地区学校供餐计划的实施(从而提高其营养影响)需要在多个治理层面做出大胆承诺和改进协调。
