Ethnicity and Suicide Risk: A Population-Based Study from England

Using multiple linked electronic health databases, we conducted a large case-control study in England from 2001 through 2019 to examine the association between ethnicity and suicide risk. Asian, Black and Other ethnic groups had a significantly lower suicide risk compared to White individuals, with those of Asian ethnicity having the lowest risk (Odds Ratio 0.53, 95% Confidence Interval 0.47-0.60). This ethnicity related suicide risk was significantly altered by socio-demographic characteristics. These factors can inform the assessment and stratification of suicide risk, as well as the targeting of public health measures designed to reduce suicide incidence.
