A high risk of schizophrenia has been found among Caribbean immigrants in the Netherlands and Great Britain. One hypothesis to explain these findings is that patients with a diagnosis of schizophrenia or patients with symptoms of psychosis not specifically diagnosed, emigrate more than the general population. Such selection might account for high rates of Surinamese patients with a diagnosis of schizophrenia in Netherlands psychiatric hospitals. We examined this hypothesis.
The files of patients with schizophrenia or patients suffering from unspecified psychosis were selected from the archives of the National Psychiatric Hospital in Surinam. These patients were traced to investigate patterns of emigration. Data from the Central Bureau for Statistics in the Netherlands and from the Central Population Bureau in Surinam provided the percentage of the general Surinamese population that emigrated to the Netherlands. The difference between the two percentages was evaluated using the chi-squared test. Using the same method the percentage of remigration from the Netherlands among Surinamese patients was compared with the percentage of remigration among the general Surinamese population.
Surinamese patients with schizophrenia or unspecified psychosis did not emigrate more frequently to the Netherlands compared with the general Surinamese population. They did remigrate significantly more frequently.
High migration rates do not explain the high hospital admission rates for schizophrenia among Surinamese in the Netherlands.
在荷兰和英国的加勒比移民中发现精神分裂症的高风险。解释这些发现的一种假设是，被诊断为精神分裂症的患者或未被明确诊断的精神病症状患者比普通人群移民更多。这种选择可能解释了荷兰精神病院中苏里南裔精神分裂症患者的高比例。我们检验了这一假设。
从苏里南国家精神病院的档案中挑选出精神分裂症患者或患有未特定化精神病的患者档案。追踪这些患者以调查移民模式。来自荷兰中央统计局和苏里南中央人口局的数据提供了移民到荷兰的苏里南普通人群的百分比。使用卡方检验评估这两个百分比之间的差异。使用相同方法，将苏里南患者中从荷兰回迁的百分比与苏里南普通人群中回迁的百分比进行比较。
与苏里南普通人群相比，患有精神分裂症或未特定化精神病的苏里南患者向荷兰移民的频率并不更高。他们回迁的频率确实显著更高。
高移民率并不能解释荷兰苏里南裔精神分裂症患者的高住院率。
