Area of Science:

  • Psychiatry
  • Epidemiology
  • Sociology

Background:

  • Hospital admission rates for schizophrenia are elevated in Afro-Caribbean immigrants compared to the white British-born population.
  • Potential confounding variables include diagnostic interpretation and demographic factors influencing admission rates.

Purpose of the Study:

  • To investigate the course and characteristics of schizophrenia in Afro-Caribbean immigrants versus white British-born patients.
  • To determine if observed differences in admission rates persist after accounting for demographic and diagnostic factors.

Main Methods:

  • Retrospective case-note review of 50 Afro-Caribbean immigrants and 41 white British-born patients diagnosed with schizophrenia.
  • Average follow-up period of 12 years, analyzing readmission rates, duration, and admission type (voluntary/involuntary).

Main Results:

  • No significant difference in the total number of readmissions between groups.
  • Shorter duration of readmissions observed in the Afro-Caribbean group.
  • Involuntary admissions were twice as common in Afro-Caribbeans, independent of age, sex, or illness type.

Conclusions:

  • The higher incidence of schizophrenia in Afro-Caribbean immigrants in Britain is confirmed.
  • Schizophrenia appears to follow a milder clinical course in Afro-Caribbean immigrants compared to the white British-born population.
