The importance of nutrition during childhood and the high prevalence of child and adolescent obesity has resulted in several countries implementing nutritional standards for school food as a way of providing healthy school food environments. Yet, there has been less focus on the barriers and facilitators influencing the process of implementing school food standards. This mixed-methods systematic review aims to address this evidence gap by synthesising the empirical evidence on the factors that may influence the implementation of school food standards. This mixed-methods systematic review will use qualitative, quantitative and mixed-methods evidence from peer-reviewed publications retrieved from the following databases; PubMed, CINAHL, Scopus, EMBASE, Medline, PsycINFO and Web of Science. Grey literature will be accessed through Google Scholar, Open Access Theses and Dissertations, OpenGrey, RIAN, EThOS, ProQuest, WorldCat, Networked Digital Library of Theses and Dissertations, and public health organisation websites will also be accessed. Screening reference lists and citation chaining of all included studies will also be undertaken. No restrictions on publication date or language will be applied, however, only primary research studies relevant to supply-side stakeholders will be eligible for inclusion. Study quality will be assessed using the Mixed Methods Appraisal Tool. Study titles and abstracts will be screened to decide whether the full-text manuscript should be retrieved. For screening reliability, a second review author will assess a random sample of 20%. Kappa statistics will be used to assess inter-rater reliability, with values of 0.75 and higher representing high agreement. Two authors will independently extract data and factors reported to influence implementation. This will be synthesized using the Theoretical Domains Framework. A comprehensive understanding of these factors can provide guidance to relevant stakeholders to enhance the adoption, implementation and sustainability of nutrition standards for school meals. : PROSPERO CRD42019117904.
儿童期营养的重要性以及儿童和青少年肥胖的高患病率，促使多个国家实施学校食品营养标准，以此营造健康的学校食品环境。然而，对于影响学校食品标准实施过程的障碍和促进因素，人们关注较少。本混合方法系统评价旨在通过综合有关可能影响学校食品标准实施的因素的实证证据，填补这一证据空白。 本混合方法系统评价将使用从以下数据库检索到的同行评审出版物中的定性、定量和混合方法证据：PubMed、CINAHL、Scopus、EMBASE、Medline、PsycINFO和Web of Science。灰色文献将通过谷歌学术、开放获取学位论文、OpenGrey、俄罗斯国家科技信息研究所（RIAN）、英国电子论文服务（EThOS）、ProQuest、WorldCat、网络数字论文图书馆获取，还将访问公共卫生组织网站。还将对所有纳入研究的参考文献列表进行筛选和引文链分析。不设出版日期或语言限制，不过，仅与供应方利益相关者相关的原始研究才有资格纳入。将使用混合方法评估工具评估研究质量。将筛选研究标题和摘要，以决定是否应检索全文手稿。为确保筛选可靠性，第二位评审作者将评估20%的随机样本。将使用kappa统计量评估评分者间信度，值为0.75及以上表示高度一致。两位作者将独立提取数据以及报告的影响实施的因素。将使用理论领域框架对其进行综合分析。全面了解这些因素可为相关利益相关者提供指导，以加强学校膳食营养标准的采用、实施和可持续性。：国际系统评价前瞻性注册库CRD42019117904。
