Aim: To estimate the risk of psychosis in the Pakistani, Bangladeshi and Indian populations in West Yorkshire as compared with British White population. Method: We used data from Early Intervention for Psychosis services on 15–35 year-olds diagnosed with first episode psychosis in 2013–2015 and local census data to calculate risks. Results: Compared with the British White population, the Pakistani population had a significantly higher risk of first episode psychosis (RR 1.31, 95% CI 1.09, 1.58). The smaller Bangladeshi population showed a similar, but non-significant, trend (RR 1.50, 95% CI 0.89, 2.53). In contrast, the Indian population had a significantly lower risk (RR 0.51, 95% CI 0.33, 0.79). Conclusion: Variable risk of psychosis among south Asian ethnic groups in West Yorkshire needs further research.

Introduction Migration is a well-established risk factor for schizo- phrenia and other psychoses (Kirkbride et al. 2011). In the UK, the African–Caribbean population is at increased risk of psychosis, but reports are less consistent for South Asians (Selton et al. 2007; Bhugra et al. 1997; Kirkbride et al. 2006; Coid et al. 2008). Yorkshire, in the north of England, is home to a number of immigrant communities from South Asia, particularly in the Bradford, Leeds and
