Understanding the social and environmental influencers of eating behaviours has the potential to improve health outcomes for young people. This review aims to explore the effectiveness of school nutrition interventions and the perceptions of young people experiencing a nutrition focused intervention or change in school food policy. A comprehensive systematic search identified studies published between 1 December 2007 to 20 February 2020. Twenty-seven studies were included: 22 quantitative studies of nutrition related outcomes and five qualitative studies reporting views and perceptions of young people (combined sample of 22,138 participants, mean ages 12-18 years). The primary outcome was nutrition knowledge/dietary behaviours, with secondary outcomes exploring body mass index (BMI) and wellbeing. Due to the heterogeneity of studies, a narrative results description is presented. The findings demonstrate that school nutrition programmes can be effective in reducing sugar, sugar sweetened beverages (SSB) and saturated fat and increasing fruit and vegetable (FV) intake. The lived experiences of young people in a school context provide valuable insights that should be considered in the development of effective school food policy and interventions. This review affirms the significant role that schools can play in supporting good nutrition in all young people and provides opportunities to inform the school food agenda.
了解影响饮食行为的社会和环境因素有可能改善年轻人的健康结果。本综述旨在探讨学校营养干预的效果，以及经历营养为重点的干预或学校食物政策变化的年轻人的看法。全面的系统搜索确定了 2007 年 12 月 1 日至 2020 年 2 月 20 日期间发表的研究。共纳入了 27 项研究：22 项与营养相关结果的定量研究和 5 项报告年轻人观点和看法的定性研究（共有 22138 名参与者，平均年龄为 12-18 岁）。主要结果是营养知识/饮食行为，次要结果是探索体重指数（BMI）和幸福感。由于研究的异质性，本研究采用叙述性结果描述。研究结果表明，学校营养计划可以有效减少糖、含糖饮料（SSB）和饱和脂肪的摄入量，增加水果和蔬菜（FV）的摄入量。年轻人在学校环境中的生活体验提供了有价值的见解，应该在制定有效的学校食物政策和干预措施时加以考虑。本综述肯定了学校在支持所有年轻人良好营养方面可以发挥重要作用，并为学校食物议程提供了信息。
