Due to continuing migration there is more interest in the mental health status of immigrants. The aim of this study is to determine the prevalence of depressive/anxiety symptoms in immigrant and native dialysis patients, and to explore if patient characteristics can explain differences. The Beck depression inventory and the beck anxiety inventory were used. Differences between native and immigrant patients were explored using logistic regression models adjusted for patient characteristics. The prevalence of depressive symptoms was 35% for 245 native patients and 50% for 249 immigrant patients. The prevalence of anxiety symptoms was 35% for native patients and 50% for immigrant patients. In addition, the prevalence for co-morbid depressive and anxiety symptoms was 20% for native patients and 32% for immigrant patients. Crude ORs for depressive/anxiety symptoms for immigrant patients versus native patients were 1.8 (1.2–2.5) and 1.7 (1.2–2.5), respectively. After adjustment for patient characteristics ORs remained the same. Clinicians should be aware that immigrant dialysis patients are more prone to develop depressive and anxiety symptoms. Cultural factors might play a role and should therefore be assessed in future research.
