Post-traumatic stress disorder (PTSD) is a psychiatric condition that has become a challenge for public health. Little research has been undertaken in military population, even less in the Latin American context. The objective is determining the prevalence and factors associated with post-traumatic stress disorder in military personnel in Lambayeque, Peru.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This is an analytic cross-sectional observational study in military staff that carried out first-line activities on the defense against COVID-19. The study population was comprised of 820 military personnel. To evaluate the factors associated with PTSD, we calculated prevalence ratios (PR) and confidence intervals at 95%, using simple and multiple regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The prevalence of PTSD was 7.8% (95% CI: 5.8%\u201310.2%). The multiple regression model showed that smoking (PR: 2.84; 95% IC: 1.14-7.09), having worked between 13 and 18 months (PR: 2.62; 95% IC: 1.20-5.75), insomnia (PR: 4.09; 95% IC: 1.90-8.83), and fear of COVID (PR: 6.20; 95% IC: 2.70-14.22) were associated with a higher prevalence of PTSD in military personnel.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We found that nearly one in ten military personnel presented PTSD. Factors associated with a higher prevalence included longer service time, smoking, insomnia, and fear of COVID-19. Although resilience showed a protective trend in crude analyses, this association was not significant after adjustment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyt.2025.1573379","type":"journal-article","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T05:32:55Z","timestamp":1761111175000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of post-traumatic stress disorder in Peruvian military: a cross-sectional study"],"prefix":"10.3389","volume":"16","author":[{"given":"Mario J.","family":"Valladares-Garrido","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cinthia Karina","family":"Pic\u00f3n-Re\u00e1tegui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
