Variation in characteristics of people with mental disorders across smoking status in the Canadian general population.

ABSTRACT: INTRODUCTION:People with mental disorders are less successful in smoking cessation efforts. This study compared the characteristics of current smokers and former smokers with mental disorders. METHODS:This was a cross-sectional study that used the Public Use Microdata File of the Canadian Community Health Survey 2012. Survey respondents with any mental health disorder in the last 12 months (n=2700), identified using the World Health Organization Composite International Diagnostic Interview instrument, were included in the analysis. Smoking status was classified based on self-report responses as current, former and never smoker. Logistic regression models were used to analyze the data. RESULTS:The odds of quitting smoking were significantly lower among people who were single or never married (widowed/divorced/separated/single) compared to those who were married or had a common-law partner (adjusted odds ratio, AOR=0.6, 95% CI: 0.4-0.9). Similarly, significantly lower odds of quitting smoking were observed among people with less than post-secondary education compared to those with post-secondary education (AOR=0.4, 95% CI: 0.3- 0.6). Also, the odds of quitting were significantly lower among immigrants, young adults, and middle-aged adults. CONCLUSIONS:People who are young or middle-aged, single or never married, less educated, and immigrants, are less likely to quit smoking. This pattern underscores the socioeconomic disparities in quitting smoking among people with mental disorders. Future research should investigate why these groups continue to smoke more often than their counterparts. This will help design the smoking cessation support that address the challenges experienced by vulnerable populations and reduce the disparities.

Project description:Multidisciplinary collaboration between clinicians, epidemiologists, neurogeneticists and statisticians on research projects has been encouraged to improve our knowledge of the complex mechanisms underlying the aetiology and burden of mental disorders. The PEGASUS-Murcia (Psychiatric Enquiry to General Population in Southeast Spain-Murcia) project was designed to assess the prevalence of common mental disorders and to identify the risk and protective factors, and it also included the collection of biological samples to study the gene-environmental interactions in the context of the World Mental Health Survey Initiative.The PEGASUS-Murcia project is a new cross-sectional face-to-face interview survey based on a representative sample of non-institutionalised adults in the Region of Murcia (Mediterranean Southeast, Spain). Trained lay interviewers used the latest version of the computer-assisted personal interview of the Composite International Diagnostic Interview (CIDI 3.0) for use in Spain, specifically adapted for the project. Two biological samples of buccal mucosal epithelium will be collected from each interviewed participant, one for DNA extraction for genomic and epigenomic analyses and the other to obtain mRNA for gene expression quantification. Several quality control procedures will be implemented to assure the highest reliability and validity of the data. This article describes the rationale, sampling methods and questionnaire content as well as the laboratory methodology.Informed consent will be obtained from all participants and a Regional Ethics Research Committee has approved the protocol. Results will be disseminated in peer-reviewed publications and presented at the national and the international conferences.Cross-sectional studies, which combine detailed personal information with biological data, offer new and exciting opportunities to study the gene-environmental interactions in the aetiology of common mental disorders in representative samples of the general population. A collaborative multidisciplinary research approach offers the potential to advance our knowledge of the underlying complex interactions and this opens the field for further innovative study designs in psychiatric epidemiology.
