背景在移民人群中，精神病的发病率一直较高。种族密度，即一个种族群体在一个特定地区的比例，被认为是一个因素，在种族共享的情况下，精神病的风险降低。然而，英国的研究结果喜忧参半。我们着手重新审视种族密度的影响，在更大的水平上的地理细节比以前的研究。方法使用大样本的患者记录，从全科医生在南东伦敦，我们能够评估邻里因素的详细下超输出区水平。这包括平均1500人，而以前研究中使用的标准是每个病房约6000人。我们按社区种族密度比较了10年内黑人（非裔加勒比人）和白色精神病的发病率。结果我们发现种族密度和精神病发病率之间存在明显的负相关。在黑人占总人口25%以上的社区，精神病发病率在统计学上不再有显著的种族差异。然而，在黑人较少代表的地方，他们的相对风险增加了近三倍[比值比（OR）2.88，95%置信区间（CI）1.89-4.39]。此外，黑人在最低密度五分之一人口中的发病率是最高密度五分之一人口中的五倍多（OR 5.24，95% CI 1.95-14.07）。然而，在区一级，这种关联要弱得多，不再具有统计学意义。结论在详细的当地社区层面上，种族密度与精神病发病率呈负相关。
Background Elevated incidence of psychotic illness has been consistently shown among migrant populations. Ethnic density, the proportion of an ethnic group in a defined area, is cited as one factor with a reduced risk of psychosis where ethnicity is shared. However, UK studies have shown mixed results. We set out to re-examine the ethnic density effect at a greater level of geographic detail than previous studies. Method Using a large sample of patient records from general practitioners in South East London, we were able to assess neighbourhood factors at the detailed lower super output area level. This comprises, on average, 1500 people compared with around 6000 per ward, the measure used in previous studies. We compared black (Afro-Caribbean) and white psychosis incidence by neighbourhood ethnic density over a 10-year period. Results We found a clear negative association between ethnic density and psychosis incidence. In neighbourhoods where black people comprised more than 25% of the population, there was no longer a statistically significant ethnic difference in psychosis rates. However, where black people were less well represented, their relative risk increased nearly threefold [odds ratio (OR) 2.88, 95% confidence interval (CI) 1.89–4.39]. Furthermore, incidence rates for black people in the lowest density quintiles were over five times greater than in the most dense quintile (OR 5.24, 95% CI 1.95–14.07). However, at ward level this association was much weaker and no longer statistically significant. Conclusions Ethnic density is inversely related to psychosis incidence at a detailed local neighbourhood level.
