Hospital admission rates for schizophrenia are higher in Afro-Caribbean immigrants to Britain than in the white British-born population. However, the reported differences in incidence and prevalence could be due to confounding variables: the diagnosis of schizophrenia might not carry the same prognostic implications in the two groups; and the differences in formal admission rates might not persist when demographic and diagnostic differences are allowed for. The case-notes of 50 Afro-Caribbean immigrants and 41 British-born white patients with a hospital diagnosis of schizophrenia were examined retrospectively, the average period covered being 12 years. There were no differences in the number of readmissions, but in the Afro-Caribbean group readmissions were shorter. Involuntary admissions were twice as common in Afro-Caribbeans and this excess was not explained by differences in age, sex, or type of illness. The reported excess of schizophrenia in Afro-Caribbean immigrants to Britain is real, but the illness seems to run a milder course than in the white British-born population.
在英国，非洲裔加勒比移民中精神分裂症的住院率高于英国本土白人。然而，报告的发病率和患病率差异可能是由于混杂变量：精神分裂症的诊断在两组中可能不具有相同的预后意义；当考虑人口统计学和诊断差异时，正式住院率的差异可能不会持续存在。对50名非洲裔加勒比移民和41名英国本土白人精神分裂症患者的病历进行了回顾性研究，平均涵盖时间为12年。再次入院次数没有差异，但在非洲裔加勒比人群体中，再次住院时间较短。非洲裔加勒比人的非自愿住院率是白人的两倍，且这种差异无法用年龄、性别或疾病类型的差异来解释。报告显示，非洲裔加勒比移民到英国后精神分裂症发病率较高这一情况属实，但这种疾病的病程似乎比英国本土白人更轻。
