The prevalence of diet-related non-communicable diseases (NCDs) are rapidly increasing in most parts of the world. In order to ameliorate the related public health burden, evidence-informed policies to improve diet need to be implemented. Financial subsidies that promote healthful consumption patterns have the potential to reduce NCD risk and may also reduce inequality if targeted at those of low socio-economic position. This protocol is for an updated systematic review of such evidence.
A systematic search strategy will be used to identify publications on fiscal intervention studies indexed in Embase, CINAHL, Web of Science, EconLit and PubMed in between January 2013 to February 2019. Two reviewers will independently sift identified citations using prespecified inclusion and exclusion criteria to inform full-text review. The outcomes of interest are: consumption patterns (% change in targeted items and in overall dietary patterns), purchasing patterns (% change) or body mass index. Pretested data capture forms will be used for double data extraction. Any inconsistencies in citation sifting or data extraction will be resolved by a third investigator and study authors will be contacted if needed. Systematic searches will be supplemented by reference checking of key articles. Study quality will be assessed and a narrative summary of findings will be produced. Meta-analyses and exploration of heterogeneity will be completed if appropriate.
The review aims to strengthen findings of the primary studies it incorporates. It will synthesise existing published aggregated patient data and only present further aggregate data. Given this, no concerns are held relating to confidentiality and informed consent due to re-use of patient data.If publications or data with ethical concerns are identified, they will be excluded from the review.Results of the systematic review will be published in full and authors will engage directly with research audiences and key stakeholders to share findings.

在世界大部分地区，与饮食相关的非传染性疾病（NCDs）的患病率正在迅速上升。为了减轻相关的公共卫生负担，需要实施基于证据的改善饮食政策。促进健康消费模式的财政补贴有可能降低非传染性疾病风险，如果针对社会经济地位较低的人群，还可能减少不平等现象。本方案旨在对这类证据进行更新的系统评价。
将采用系统检索策略，以识别2013年1月至2019年2月期间在Embase、CINAHL、科学引文索引、EconLit和PubMed中索引的关于财政干预研究的出版物。两名评审员将使用预先指定的纳入和排除标准独立筛选已识别的引文，为全文评审提供依据。感兴趣的结果包括：消费模式（目标项目和总体饮食模式的百分比变化）、购买模式（百分比变化）或体重指数。将使用预先测试的数据收集表进行双重数据提取。在引文筛选或数据提取中出现的任何不一致之处将由第三位研究人员解决，如有需要将与研究作者联系。系统检索将辅以对关键文章的参考文献检查。将评估研究质量并生成研究结果的叙述性总结。如有适当情况，将完成荟萃分析和异质性探索。
该综述旨在加强其所纳入的主要研究的结果。它将综合现有的已发表的汇总患者数据，仅呈现进一步的汇总数据。鉴于此，由于重复使用患者数据，不存在与保密和知情同意相关的问题。如果识别出存在伦理问题的出版物或数据，将将其排除在综述之外。系统评价的结果将全文发表，作者将直接与研究受众和关键利益相关者接触以分享研究结果。
