Reports of an increased incidence of schizophrenia in Afro-Caribbean immigrants to the UK are a matter of much debate. It is of interest, therefore, that in the 1970s and 1980s many immigrants from Surinam and The Netherlands Antilles have settled in The Netherlands. The purpose of our study was to compare the risk of a first admission for schizophrenia for Surinamese- and Antillean-born persons aged 15-39 years to that for their Dutch-born peers in the period 1983-1992.
We used data from the Dutch psychiatric registry. Age-adjusted relative risks were calculated using Poisson regression analysis.
The risk for the immigrants was found to be three to four times higher than that for the Dutch-born. Age-adjusted relative risks were significantly higher for male than for female immigrants.
The results provide evidence of an increased incidence in these immigrant groups and support similar findings on Afro-Caribbeans in the UK. Migration from Surinam was on such a large scale that selective migration of persons at risk for the disorder is unlikely to account entirely for these findings.
有报告称，在英国的非洲加勒比移民中精神分裂症发病率有所上升，这一情况备受争议。因此，值得关注的是，在20世纪70年代和80年代，许多来自苏里南和荷属安的列斯群岛的移民定居在了荷兰。我们研究的目的是比较1983年至1992年期间，15至39岁的苏里南和安的列斯群岛出生者首次因精神分裂症入院的风险与荷兰出生的同龄人相比情况如何。
我们使用了荷兰精神病学登记处的数据。采用泊松回归分析计算年龄调整后的相对风险。
发现移民的风险比荷兰出生者高3至4倍。年龄调整后的相对风险，男性移民显著高于女性移民。
研究结果证明这些移民群体的发病率有所上升，并支持了在英国对非洲加勒比人的类似研究结果。从苏里南的移民规模如此之大，以至于有患该疾病风险的人群选择性移民不太可能完全解释这些结果。
