BACKGROUND
School feeding programs are beneficial for the physical, mental, and psychosocial development of school-age children and adolescents, particularly those in low- and middle-income countries (LMICs). While school feeding programs are ubiquitous in LMICs, the specific benefits of school feeding programs are unclear. The aim of this systematic review and meta-analysis is to evaluate the impacts of school feeding programs on the educational and health outcomes of children and adolescents in LMICs.
METHODS
Rigorously designed interventional studies on the impacts of school feeding on nutritional and health outcomes of children and adolescents receiving primary or secondary education in LMICs will be included. The following information sources were used to identify relevant published or unpublished studies: MEDLINE, EMBASE, CINAHL, the Cochrane Library, and governmental or organizational websites. The risk of bias of randomized and non-randomized studies will be assessed using the Cochrane Risk of Bias tool and the ROBINS-I tool, respectively. Two reviewers will independently conduct the selection of studies, data extraction, and assessment of the risk of bias. A narrative synthesis of all the included studies will be provided. Meta-analyses will be performed whenever appropriate. Heterogeneity of effects will be assessed by I, subgroup analyses, and meta-regression. The certainty of evidence for each outcome will be assessed using the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) approach.
DISCUSSION
The design and implementation of school feeding programs in LMICs should be based on the understanding of the benefits of such programs. This work will provide a crucial evidence base for the educational and health benefits of school feeding on children and adolescents in LMICs.
SYSTEMATIC REVIEW REGISTRATION
This protocol was submitted for registration with the International Prospective Register of Systematic Reviews (PROSPERO) on November 18, 2019 (registration number: pending).
背景
学校供餐计划有益于学龄儿童和青少年的身体、心理和社会心理发展，尤其是在中低收入国家（LMICs）。虽然学校供餐计划在 LMICs 中无处不在，但学校供餐计划的具体益处尚不清楚。本系统评价和荟萃分析旨在评估学校供餐计划对 LMIC 儿童和青少年教育和健康结果的影响。
方法
本研究将纳入关于学校供餐对接受小学或中学教育的儿童和青少年营养和健康结果影响的严格设计的干预性研究。使用以下信息来源确定相关的已发表或未发表的研究：MEDLINE、EMBASE、CINAHL、Cochrane 图书馆和政府或组织网站。将使用 Cochrane 偏倚风险工具和 ROBINS-I 工具分别评估随机和非随机研究的偏倚风险。两名评审员将独立进行研究选择、数据提取和偏倚风险评估。将对所有纳入的研究进行叙述性综合。只要适当，将进行荟萃分析。通过 I 、亚组分析和荟萃回归评估效应的异质性。将使用推荐评估、制定与评价分级（GRADE）方法评估每个结局的证据确定性。
讨论
LMICs 中学校供餐计划的设计和实施应基于对这些计划益处的理解。这项工作将为 LMIC 儿童和青少年学校供餐在教育和健康方面的益处提供重要的证据基础。
