OBJECTIVES Previous large-scale population studies have reported that gay and bisexual men may be at increased risk for health disparities. This study was conducted to determine whether health status and health risk behaviours of Canadian men vary based on sexual orientation identity. METHODS Utilizing the Canadian Community Health Survey data (Cycle 2.1,(More)
Even though individuals with psychiatric conditions have a prevalence of smoking approximately 2-4 times greater than the general population, surprisingly little evidence exists to inform an assessment of the full range of tobacco-related mortality in such populations. The current study aims to provide mortality estimates for conditions causally related to(More)
OBJECTIVE To add to the limited data on the prevalence, clinical characteristics, and treatment of bipolar disorder (BD) among immigrants. METHOD Data were obtained from a large epidemiologic survey, the Canadian Community Health Survey-Mental Health and Well-Being (CCHS 1.2). Lifetime prevalence rates of BD were compared between immigrant and(More)
OBJECTIVE This study reports on the lifetime prevalence and illness characteristics of bipolar disorder (BD) in a large, representative sample of Canadians.

This representative, cross-sectional survey, conducted by Statistics Canada in 2002, examines the(More)
OBJECTIVE Although anxiety disorders, including social phobia (SP), are common among older adults, very little is known about the epidemiology of SP in later life. METHOD Using data drawn from a large, nationally representative sample of older adults from Canada (N=12,792), the authors estimate lifetime and 12-month prevalence of social phobia and examine(More)
OBJECTIVE Very little epidemiological work has examined comorbidity between depression and anxiety disorders in community-dwelling older adults, despite the fact these disorders are known to co-occur in younger adults and that this co-occurrence is associated with greater clinical severity. In this study, the authors examine psychiatric comorbidity and(More)
We examined the effectiveness of a teacher-based rating scale called the teacher estimation of activity form (TEAF) to screen for developmental coordination disorder (DCD) in children. A random selection of 15 of 75 schools from the District School Board of Niagara in Ontario, Canada was chosen for this study. Every consented child in Grade 4 (n=502) was(More)
Current tobacco-control strategies seek to inhibit and reduce smoking among adolescents. However, such strategies are probably undermined by the contraband tobacco market. Using data from Canada's 2006/2007 Youth Smoking Survey, we found that 13.1% of respondents who were daily smokers reported that contraband cigarettes were their usual brand. They(More)
OBJECTIVE Structured diagnostic interviews are very time-consuming and therefore increase both the expense and the respondent burden in epidemiologic surveys. A 2-staged interview that screens potential cases before the full diagnostic instrument is administered has the potential to greatly reduce the average interview length. In this paper, we evaluate 2(More)
AIM Children with developmental coordination disorder (DCD) are known to participate in active play less than typically developing children. However, it is not known whether the activity deficit between children with and without DCD widens or diminishes over time. METHOD Data were obtained from a large, prospective cohort study of children (baseline(More)
