BACKGROUND Understanding of ethnic disparities in suicide in England and Wales is poor as ethnicity is not recorded on death certificates. Using linked data, we examined variations, by sex, in suicide rates in England and Wales by ethnicity and migrant and descendant status. METHODS Using the Office for National Statistics 2012-19 mortality data linked to the 2011 census from the Public Health Research Database, we calculated the age-standardised suicide rates by sex for each of the 18 self-identified ethnicity groups in England and Wales. We present rates by age, sex, and methods used for suicide by ethnic group. We estimated age-adjusted and sex-adjusted incidence rate ratios (IRRs) using Poisson regression models for each minority ethnic group compared with the majority population. We involved people with lived experience in the research. FINDINGS Overall, 31 644 suicide deaths occurred over the study period, including 3602 (11%) in people from minority ethnic backgrounds, with a mean age of death of 43·3 years (SD 17·0, range 13-96). Almost all minority ethnic groups had a lower rate of suicide than the White British majority, apart from individuals who identified as being from a Mixed heritage background or White Gypsy or Irish Travellers. In females who identified as Mixed White and Caribbean, the suicide IRR was 1·79 (95% CI 1·45-2·21) compared with the White British majority; in those who identified as White Gypsy or Irish Travellers, the IRR was 2·26 (1·42-3·58). Rates in males identifying as from these two groups and those identifying as White Irish were similar to the White British majority. Compared with the non-migrant population, migrants had a lower rate of suicide regardless of ethnicity, but in the descendant population, people from a Mixed ethnicity background had a higher risk of suicide than the White British majority. INTERPRETATION There are ethnic disparities in suicide mortality in England and Wales, but the reasons for this are unclear. The higher rate in previously overlooked minority ethnic groups warrants further attention. FUNDING Wellcome Trust.

英格兰和威尔士的种族与自杀：一项全国关联队列研究。


背景 人们对英格兰和威尔士自杀的种族差异了解甚少，因为死亡证明上没有记录种族。使用关联数据，我们研究了英格兰和威尔士按种族、移民和后裔身份划分的自杀率的性别差异。方法 使用国家统计局 2012-19 年公共卫生研究数据库中与 2011 年人口普查相关的死亡率数据，我们计算了英格兰和威尔士 18 个自我认同的族裔群体中按性别划分的年龄标准化自杀率。我们按年龄、性别和种族群体的自杀方法列出了自杀率。我们使用泊松回归模型估计了每个少数族裔群体与大多数人口的年龄调整和性别调整发病率比（IRR）。我们让有生活经验的人参与了这项研究。结果 总体而言，研究期间发生了 31 644 例自杀死亡事件，其中 3602 例（11%）为少数民族背景的人，平均死亡年龄为 43·3 岁（SD 17·0，范围 13-96）。几乎所有少数族裔的自杀率都低于占多数的英国白人，除了混血背景或白人吉普赛人或爱尔兰旅行者之外。与占多数的英国白人相比，在白人和加勒比海混血女性中，自杀 IRR 为 1·79 (95% CI 1·45-2·21)；在那些被认定为白人吉普赛人或爱尔兰旅行者的人中，IRR 为 2·26 (1·42-3·58)。来自这两个群体的男性和爱尔兰白人的男性比例与英国白人多数相似。 与非移民人口相比，无论种族如何，移民的自杀率都较低，但在后代人口中，混血背景的人比占多数的英国白人的自杀风险更高。解释 英格兰和威尔士的自杀死亡率存在种族差异，但其原因尚不清楚。以前被忽视的少数族裔群体的较高比率值得进一步关注。资助威康信托。
