Census data from the Danish island of Samsø have provided information on all but 20% of the population. Fifty per cent of the population with past or present mental illness had been referred to the psychiatric service during the 18-year-period 1957--74; the proportion varied from 85% for patients with psychoses (100% for schizophrenic patients, and 90% for manic-depressive patients) to 43% with non-psychotic disorders. The frequency of past and present mental illness was 24%, higher for women with manic-depressive disorders, psychogenic (reactive) psychoses, and neuroses. The possible reasons for these and other findings are discussed.
来自丹麦萨姆索岛的人口普查数据涵盖了除20%人口之外的所有信息。在1957年至1974年的18年期间,过去或现在患有精神疾病的人口中有50%曾被转诊至精神科服务机构;这一比例从患有精神病的患者的85%(精神分裂症患者为100%,躁郁症患者为90%)到患有非精神病性障碍的患者的43%不等。过去和现在患有精神疾病的频率为24%,患有躁郁症、心因性(反应性)精神病和神经症的女性患者这一比例更高。文中讨论了这些以及其他发现的可能原因。
