CMDs were assessed using the General Health Questionnaire (GHQ-12), and PTSD using the Impact of Event Scale-Revised (IES-R). Multivariate logistic regressions identified predictors of CMD and PTSD. The study included 371 HCWs in 2020 and 167 in 2021. The CMD prevalence was 34.3% (95% confidence interval (CI): 29.5\u201339.4) in 2020 and 30.5% (95% CI: 23.7\u201338.1) in 2021. The PTSD prevalence was 25.4% (95% CI: 21.0\u201330.2) in 2020 and 32.7% (95% CI: 25.6\u201340.5) in 2021. Factors increasing CMD odds included lower education (adjusted odds ratio (AOR) = 3.71, 95% CI: 1.60\u20138.61), lack of physical activity (AOR = 2.23, 95% CI: 1.33\u20133.73), and experiencing COVID-19 symptoms (AOR = 1.64, 95% CI: 1.02\u20132.64) in 2020; chronic diseases (AOR = 3.14, 95% CI: 1.34\u20137.35) and SARS-CoV-2 testing (AOR = 3.39, 95% CI: 1.13\u201310.17) raised CMD odds in 2021. Frontline HCWs had lower CMD odds in 2020 (AOR = 0.60, 95% CI: 0.36\u20131.00) and 2021 (AOR = 0.33, 95% CI: 0.14\u20130.75). PTSD was associated with having COVID-19 symptoms (AOR = 2.06, 95% CI: 1.23\u20133.45), living with high-risk individuals (AOR = 1.75, 95% CI: 1.03\u20132.95), and losing loved ones (AOR = 1.86, 95% CI: 1.09\u20133.17) in 2020. Chronic diseases increased PTSD odds in 2020 (AOR = 2.20, 95% CI: 1.25\u20133.86) and 2021 (AOR = 2.30, 95% CI: 1.03\u20135.13), while age decreased them in 2020 (AOR = 0.95, 95% CI: 0.93\u20130.98) and 2021 (AOR = 0.95, 95% CI: 0.91\u20130.99). Younger HCWs with chronic conditions living with high-risk individuals were particularly affected. These findings highlight the urgent need for targeted emotional support and stress management programs for HCWs.<\/jats:p>","DOI":"10.3390\/ijerph22020271","type":"journal-article","created":{"date-parts":[[2025,2,13]],"date-time":"2025-02-13T04:03:35Z","timestamp":1739419415000},"page":"271","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prevalence and Factors Associated with Common Mental Disorders and Posttraumatic Stress Disorder Among Healthcare Workers in a Reference Center for Infectious Diseases During the COVID-19 Pandemic: A Survey-Based Cross-Sectional Study"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9633-4512","authenticated-orcid":false,"given":"Patr\u00edcia","family":"Guimar\u00e3es","sequence":"first","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9387-8645","authenticated-orcid":false,"given":"Raquel","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rocicley","family":"Amud","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Elisa","family":"Bezerra","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paula","family":"Rigolon","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eunes","family":"Milhomem","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Luiz","family":"Lessa","sequence":"additional","affiliation":[{"name":"Institute of Psychiatry, Federal University of Rio de Janeiro, Rio de Janeiro 22290-140, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3545-5238","authenticated-orcid":false,"given":"Guilherme","family":"Calvet","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9947-2291","authenticated-orcid":false,"given":"Sonia","family":"Passos","sequence":"additional","affiliation":[{"name":"Oswaldo Cruz Foundation, Evandro Chagas National Institute of Infectious Diseases, Rio de Janeiro 21040-360, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/j.comppsych.2011.02.003","article-title":"Depression after exposure to stressful events: Lessons learned from the severe acute respiratory syndrome epidemic","volume":"53","author":"Liu","year":"2012","journal-title":"Compr.
