Given the unprecedented nature of the COVID-19 crisis and the importance of early implementation of prevention programs, it is essential to understand better its potential impacts on various food security dimensions and indicators.
Research databases, including Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Public Health Register, PubMed/MEDLINE, SCOPUS, EMBASE, CINAHL, Web of science, and Google Scholar, will be searched using a search strategy and keywords developed in collaboration with librarians. The review will include all field and community trials and observational studies in all population groups. Searching electronic databases, study selection, and data extraction will be conducted by two researchers independently. Four critical appraisal tools will be used to assess the quality of included studies according to the study design: The Joanna Briggs Institute (JBI) Prevalence Critical Appraisal tool, the JBI critical appraisal checklist for randomized control/pseudo-randomized trial, descriptive/case series, and comparable cohort/case-control. These tools were initially designed for use in systematic reviews. A narrative synthesis will be implemented to summarize findings if meta-analyses are not appropriate.
The current systematic review results can be used to predict the effect of COVID-19 on the individuals' and households' food security, especially in vulnerable populations, and develop effective interventions. This review can provide information for policymakers to better understand the factors influencing the implementation of these interventions and inform decision-making to improve food security.
The present study registration number in the international prospective register of systematic reviews (PROSPERO) is CRD42020185843.
鉴于 COVID-19 危机的空前性质，以及早期实施预防计划的重要性，因此有必要更好地了解其对各种粮食安全层面和指标的潜在影响。
将使用与图书馆员合作制定的搜索策略和关键词，在 Cochrane 对照试验中心注册库（CENTRAL）、Cochrane 公共卫生登记处、PubMed/MEDLINE、SCOPUS、EMBASE、CINAHL、Web of science 和 Google Scholar 等研究数据库中进行搜索。该综述将包括所有实地和社区试验以及所有人群组的观察性研究。两名研究人员将独立进行电子数据库搜索、研究选择和数据提取。将根据研究设计使用四个关键评估工具来评估纳入研究的质量：Joanna Briggs 研究所（JBI）流行率关键评估工具、JBI 随机对照/伪随机试验、描述性/病例系列和可比队列/病例对照的关键评估清单。这些工具最初是为系统评价而设计的。如果不适合进行荟萃分析，则将实施叙述性综合来总结研究结果。
目前的系统评价结果可用于预测 COVID-19 对个人和家庭粮食安全的影响，尤其是在弱势群体中，并制定有效的干预措施。该综述可为政策制定者提供信息，以更好地了解影响这些干预措施实施的因素，并为改善粮食安全做出决策提供信息。
本研究在国际前瞻性系统评价登记库（PROSPERO）中的注册号为 CRD42020185843。
