DOES THE INCREASED RATE OF SCHIZOPHRENIA DIAGNOSIS IN AFRICAN-CARIBBEAN MEN IN THE UK SHOWN BY THE AESOP STUDY REFLECT CULTURAL BIAS IN HEALTHCARE?

Introduction: The UK-based AESOP study conducted over a two-year period in three UK sites simultaneously (London, Nottingham, and Bristol), is the largest study to date to conduct a first contact case-control study of psychosis. The study found that rates of schizophrenia were markedly elevated in both African-Caribbean and Black African people, in both sexes and across all age groups. Subjects and methods: English language literature published up to 2016 was searched. The initial search included: PubMed, The Cochrane Library, and Web of Science. A second search was conducted using Medical Subject Headings (MeSH) and keywords. Studies selected for retrieval were assessed by two independent reviewers. Results: The search yielded eight results, all of which supported the conclusion of an increased incidence of schizophrenia in Black African and Black Caribbean population in the AESOP study. Conclusion: England is a multicultural landscape; multiplicity of cultures makes diagnosis difficult. The lessons we must learn from the AESOP study is the need for transcultural training and the removal of blinding to ethnicity when a large epidemiological study is conducted – psychiatrists need to be cognisant of cultures and aware of the context of symptoms
