Mental Health Status, Health Care Utilisation, and Service Satisfaction among Immigrants in Montreal: An Epidemiological Comparison.
To examine variations between immigrants and nonimmigrants in 1) prevalence of common mental disorders and other mental health variables; 2) health service utilisation for emotional problems, mental disorders, and addictions, and 3) health service satisfaction.



This article is based on a longitudinal cohort study conducted from May 2007 to the present: the Epidemiological Catchment Area Study of Montreal South-West (ZEPSOM). Participants were followed up at 4 time points (T1, n = 2433; T4, n = 1095). Core exposure variables include immigrant status (immigrant vs. nonimmigrant), duration of residence, and region of origin. Key outcome variables included mental health status, health service utilisation, and health service satisfaction. Data were analysed both cross-sectionally and longitudinally.



Immigrants had been in Canada for 20 years on average. Immigrants had significantly lower rates of high psychological distress (32.6% vs. 39.1%, P = 0.016), alcohol dependence (1.4% vs. 3.9%, P =0.010), depression (5.2% vs. 9.2%, P = 0.008), and various other mental disorders. They had significantly higher scores of mental well-being (48.9 vs. 47.1 score, P = 0.014) and satisfaction with social (34.0 vs. 33.4 score, P = 0.021) and personal relationships (16.7 vs. 15.6 score, P < 0.001). Immigrants had significantly lower rates of health service utilisation for emotional problems, mental disorders, and addictions and significantly higher rates of health service satisfaction at all time points. Asian and African immigrants had particularly low rates of utilisation and high rates of satisfaction.



Immigrants had better overall mental health than nonimmigrants.
