Schizophrenia is diagnosed more frequently among Afro-Caribbeans in Britain than among white British controls. Studies among the general population indicate that non-psychotic disorders such as anxiety, depression and functional somatic symptoms are the commonest expression of psychiatric morbidity. Yet, among Afro-Caribbean primary care attenders, rates of anxiety and depression appear lower than in the general population. This finding is at odds with the reportedly higher rates of schizophrenia among this group. The majority of authors favour socio-cultural explanations to account for the higher rates of schizophrenia. Yet many of the factors that are evoked to account for the greater incidence of schizophrenia would be expected to lead to higher rates of non-psychotic disorders in primary care settings. Possible explanations for these apparently contradictory findings are discussed.
在英国，非裔加勒比人中精神分裂症的诊断率高于英国白人对照组。对普通人群的研究表明，焦虑、抑郁和功能性躯体症状等非精神病性障碍是精神疾病发病率最常见的表现形式。然而，在非裔加勒比裔初级保健就诊者中，焦虑和抑郁的发病率似乎低于普通人群。这一发现与该群体中据报道较高的精神分裂症发病率不一致。大多数作者倾向于用社会文化解释来解释精神分裂症的高发病率。然而，许多被引用来解释精神分裂症发病率较高的因素，预计会导致初级保健机构中非精神病性障碍的发病率更高。本文讨论了这些明显矛盾的发现的可能解释。
