School-based nutrition interventions can support healthy eating in children.
To identify components of school-based nutrition interventions and synthesize the impact on consumption of fruits and vegetables (FV) and nutrition knowledge (NK) in children aged 4-12 y.
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and PICOS inclusion criteria, relevant systematic reviews and/or meta-analyses, written in English, published between 2010 and August 2020, across 6 databases were identified.
Two reviewers independently performed data extraction and assessed the study quality.
The JBI Critical Appraisal Instrument for Systematic Reviews and Research Syntheses was used to assess review quality, and the Grading of Recommendations Assessment, Development, and Evaluation approach was used to rate strength of evidence.
From 8 included reviews, 7 intervention components were identified: FV provision, gaming/computer-delivered, curriculum, experiential learning, reward/incentives, nudging, and caregiver involvement. FV provision had the greatest effect on F intake, gaming/computer-delivered on V intake, and curriculum on NK.
FV provision and gaming/computer-delivered components showed, overall, some positive effect on FV intake, as did the curriculum component on NK. More evidence evaluating single-component effectiveness that considers the setting and context of nutrition interventions is required to strengthen the evidence base.

学校营养干预可以支持儿童的健康饮食。
确定学校营养干预的组成部分，并综合评估其对 4-12 岁儿童水果和蔬菜摄入以及营养知识的影响。
根据系统评价和荟萃分析的首选报告项目和 PICOS 纳入标准，从 6 个数据库中确定了相关的系统评价和/或荟萃分析，这些研究均发表于 2010 年至 2020 年 8 月期间，且为英文。
两名审查员独立进行数据提取和研究质量评估。
使用 JBI 系统评价和研究综合评估工具对综述质量进行评估，并使用推荐评估、制定和评估方法对证据强度进行评级。
从纳入的 8 篇综述中，确定了 7 个干预组成部分：提供水果和蔬菜、游戏/计算机传递、课程、体验式学习、奖励/激励、提示和照顾者参与。提供水果和蔬菜对水果摄入的影响最大，游戏/计算机传递对维生素摄入的影响最大，而课程对营养知识的影响最大。
提供水果和蔬菜以及游戏/计算机传递的干预措施总体上对水果和蔬菜的摄入量有一定的积极影响，而课程干预措施对营养知识也有一定的影响。需要更多评估单一组成部分有效性的证据，同时考虑营养干预措施的设置和背景，以加强证据基础。
