Studies assessing the nutritional quality of food provided to the homeless population show deficiencies in micronutrients and excess fat, sugar, and salt. The availability of cheap, energy-dense and nutrient-poor food has changed the profile of people living with homelessness from primarily underweight to obese in western countries. Many factors influence the nutritional quality of food provided to the homeless population such as budget and time constraints, food donations and limited equipment. Nutrient intakes in this population are unlikely to be met outside of charitable meal programmes, making the nutritional quality of these meals crucial. This review will synthesise mixed methods literature with the overarching aim of understanding the determinants of the nutritional quality of food provided to the homeless population.
This mixed methods systematic review will include English language empirical research studies from Europe, North America and Oceania. The following electronic databases have been chosen for this review: SCOPUS, EMBASE, PsycINFO, EBSCOHost SocIndex and CINAHL. The grey literature databases OpenGrey and ProQuest will also be searched. Quality appraisal will be conducted using the Mixed-Methods Appraisal Tool. Two independent reviewers will be included in study selection, data extraction and quality appraisal. A third reviewer will resolve conflicts. Thematic synthesis will be employed.
Results will be organised based on a determinants of health model, to highlight areas where change may be effective, thereby making it more likely to be useful to practitioners and researchers. The iterative steps in the systematic review process will be the focus of this article. Findings from this review will be used to develop best-practice guidelines for stakeholders such as policy makers and service providers to improve the nutritional quality of food provided in the homeless sector.
This mixed methods systematic review protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO): CRD42021289063.
评估提供给无家可归人群的食物的营养质量的研究表明，这些食物在微量营养素方面存在不足，而在脂肪、糖和盐方面则存在过剩。在西方国家，廉价、高热量但营养贫乏的食物的供应改变了无家可归人群的特征，使他们从主要体重不足转变为肥胖。许多因素影响提供给无家可归人群的食物的营养质量，例如预算和时间限制、食物捐赠和有限的设备。除了慈善餐食计划外，这些人群的营养摄入量不太可能得到满足，因此这些餐食的营养质量至关重要。本综述将综合使用混合方法文献，以了解影响提供给无家可归人群的食物的营养质量的决定因素。
本混合方法系统综述将包括来自欧洲、北美和大洋洲的英语实证研究。选择了以下电子数据库进行本综述：SCOPUS、EMBASE、PsycINFO、EBSCOHost SocIndex 和 CINAHL。还将搜索灰色文献数据库 OpenGrey 和 ProQuest。使用混合方法评价工具进行质量评价。将有两名独立的评审员参与研究选择、数据提取和质量评价。如有冲突，将由第三名评审员解决。将采用主题综合法。
结果将根据健康决定因素模型进行组织，以突出可能有效的改变领域，从而使其更有可能对实践者和研究人员有用。本文将重点介绍系统评价过程中的迭代步骤。本综述的结果将用于为利益相关者（如政策制定者和服务提供者）制定最佳实践指南，以改善无家可归者部门提供的食物的营养质量。
