Growing ethnic diversity in the UK has made it increasingly important to determine the presence of ethnic health inequalities. There has been no systematic review that has drawn together research on ethnic differences in mortality in the UK.
All types of observational studies that compare all-cause mortality between major ethnic groups and the white majority population in the UK will be included. We will search Medline (OvidSP), Embase (OvidSP), Scopus and Web of Science and search the grey literature through conference proceedings and online thesis registries. Searches will be carried out from inception to 2 August 2019 with no language or other restrictions. Database searches will be repeated prior to publication to identify new articles published since the initial search. We will conduct forward and backward citation tracking of identified references and consult with experts in the field to identify further publications and ongoing or unpublished studies. Two reviewers will independently screen studies and extract data. Two reviewers will independently assess the quality of included studies using the Newcastle-Ottawa Scale. If at least two studies are located for each ethnic group and studies are sufficiently homogeneous, we will conduct a meta-analysis. If insufficient studies are located or if there is high heterogeneity we will produce a narrative summary of results.
As no primary data will be collected, formal ethical approval is not required. The findings of this review will be disseminated through publication in peer reviewed journals and conference presentations.

英国日益多样化的族裔群体使得确定族裔健康不平等现象的存在变得越来越重要。目前还没有系统的综述能够综合研究英国族裔间的死亡率差异。
所有类型的观察性研究，只要是比较英国主要族裔群体与白人多数族裔人群之间全因死亡率的研究，都将被纳入。我们将检索 Medline（OvidSP）、Embase（OvidSP）、Scopus 和 Web of Science，并通过会议论文集和在线论文注册处搜索灰色文献。检索将从建库开始一直持续到 2019 年 8 月 2 日，不设语言或其他限制。在发表前，我们将重复数据库检索，以确定自初始检索以来发表的新文章。我们将进行已识别参考文献的前瞻性和回溯性引文追踪，并咨询该领域的专家，以确定进一步的出版物和正在进行或未发表的研究。两位评审员将独立筛选研究并提取数据。两位评审员将使用纽卡斯尔-渥太华量表独立评估纳入研究的质量。如果每个族裔群体至少有两项研究且研究具有足够的同质性，我们将进行荟萃分析。如果研究数量不足或存在高度异质性，我们将对结果进行叙述性总结。
由于不会收集原始数据，因此不需要正式的伦理批准。本综述的结果将通过发表在同行评议期刊和会议报告中进行传播。
