↵* p values for major depressive episode and psychological distress are estimated for the percent difference between the 2002 and 2012 point estimates; p values for all other indicators were derived from the Poisson regression model for the prevalence rates across CCHS periods adjusted for sex.
↵† Results for major depressive episode and psychological distress were derived from the CCHS Mental Health and Well-being Cycle 1.2 (2002) and the CCHS – Mental Health (2012) surveys. All other variables were derived from the CCHS .1 annual surveys.
↵‡ Bootstrap methods were used to derive 95% CIs.
Source: Data were derived from the Ontario components of Statistics Canada’s CCHS. Estimates were sex-standardized to the 2006 Ontario census population and were weighted by the survey sample weight.
