Objective: To compare mood disorder (MD) prevalence in Quebec in 2006, and compare health services and medication use, mortality and morbidity in patients with MD based on sex and the dwelling sector level of material and social deprivation. The objective was also to identify subgroups of individuals using health services in a larger proportion and having a higher risk of morbidity and mortality.

Method: We conducted a secondary analysis of the Régie de l’assurance maladie du Québec medico-administrative data. The cohort is composed of adults diagnosed with MD and living in Quebec in 2006. Variables include: physician consultation, medication demand, consultation for substance or alcohol abuse, emergency visit, hospitalization for a mental disorder, and death. Dwelling sector types are defined by crossing Pampalon material and social deprivation quintiles.

Results: MD prevalence in 2006 was 3.06% (177 850 patients), with prevalence in women 1.7-fold with respect to men. Findings show a higher MD prevalence as well as a higher mortality and morbidity rate in materially and socially deprived dwelling sectors. Young men also represent a specifically vulnerable subgroup for many study variables.

Conclusion: Public policies aimed at improving material conditions (income, education, employment) and breaking out social isolation would have an important impact on the population mental health. Public health program development should pay close attention to young men population.
