The prevalence of PTSD was measured using the PTSD Checklist for DSM-5 (PCL-5) Cross-sectional associations were quantified using logistic regression, while controlling for sociodemographic characteristics.<\/p>\n \t<\/sec>\t\t\n\t<sec>\t\t\n        <title>Results<\/title>\t\t\t\n\t\t\t<p>The overall prevalence of PTSD was 6.9%. Factors associated with higher PTSD prevalence were female gender; younger age; lower income (females only); living in an urban area; frontline worker status or not being at work in the past week (males only); fair or poor mental health; a weak sense of community belonging; symptoms of generalized anxiety disorder and major depressive disorder; suicidal ideation; heavy alcohol use; daily cannabis use; increased alcohol and cannabis use since the start of the pandemic; decreased alcohol consumption since the start of the pandemic (males only); concerns about violence in the home; and negative impacts of the pandemic.<\/p>\n\t\t<\/sec>\t\n\t   <sec>\t\t\n         <title>Conclusion<\/title>\t\t\t\n\t\t\t<p>PTSD prevalence in Canada varies significantly across sociodemographic groups and is more common among those with indicators of lower mental health and well-being, as well as those more adversely affected by the COVID-19 pandemic. Ongoing and enhanced surveillance of PTSD in Canada is important to better understand and address the burden and impacts of this condition.<\/p>\n\t\t <\/sec>","DOI":"10.24095\/hpcdp.45.1.02","type":"journal-article","created":{"date-parts":[[2025,1,15]],"date-time":"2025-01-15T14:35:53Z","timestamp":1736951753000},"page":"20-38","source":"Crossref","is-referenced-by-count":9,"title":["Prevalence of posttraumatic stress disorder (PTSD) in Canada during the COVID-19 pandemic: results from the Survey on COVID-19 and Mental Health"],"prefix":"10.24095","volume":"45","author":[{"given":"Murray","family":"Weeks","sequence":"first","affiliation":[{"name":"Centre for Surveillance and Applied Research, Health Promotion and Chronic Disease Prevention Branch, Public Health Agency of Canada, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danielle","family":"Marion","sequence":"additional","affiliation":[{"name":"Centre for Surveillance and Applied Research, Health Promotion and Chronic Disease Prevention Branch, Public Health Agency of Canada, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne-Marie","family":"Robert","sequence":"additional","affiliation":[{"name":"Centre for Surveillance and Applied Research, Health Promotion and Chronic Disease Prevention Branch, Public Health Agency of Canada, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
