Previous evidence has suggested an association between OSA and posttraumatic stress disorder (PTSD) but is limited by possible selection bias. High-quality research on this association with a careful evaluation of possible confounders may yield important mechanistic insight into both conditions and improve treatment efforts.<\/jats:p><\/jats:sec>Objective<\/jats:title>To investigate the association of current PTSD symptoms and PTSD diagnosis with OSA.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>This cross-sectional study of twin pairs discordant for PTSD, which allows for adjustment for familial factors, was conducted using in-laboratory polysomnography from March 20, 2017, to June 3, 2019. The study sample comprised male veteran twins recruited from the Vietnam Era Twin Registry. The data analysis was performed between June 11, 2022, and January 30, 2023.<\/jats:p><\/jats:sec>Exposure<\/jats:title>Symptoms of PTSD in twins who served in the Vietnam War. Diagnosis of PTSD was a secondary exposure.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Obstructive sleep apnea was assessed using the apnea-hypopnea index (AHI) (\u22654% oxygen saturation criterion as measured by events per hour) with overnight polysomnography. Symptoms of PTSD were assessed using the PTSD Checklist (PCL) and structured clinical interview for PTSD diagnosis.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 181 male twins (mean [SD] age, 68.4 [2.0] years) including 66 pairs discordant for PTSD symptoms and 15 pairs discordant for a current PTSD diagnosis were evaluated. In models examining the PCL and OSA within pairs and adjusted for body mass index (BMI) and other sociodemographic, cardiovascular, and psychiatric risk factors (including depression), each 15-point increase in PCL was associated with a 4.6 (95% CI, 0.1-9.1) events-per-hour higher AHI. Current PTSD diagnosis was associated with an adjusted 10.5 (95% CI, 5.7-15.3) events-per-hour higher AHI per sleep-hour. Comparable standardized estimates of the association of PTSD symptoms and BMI with AHI per SD increase (1.9 events per hour; 95% CI, 0.5-3.3 events per hour) were found.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>This cross-sectional study found an association between PTSD and sleep-disordered breathing. The findings have important public health implications and may also enhance understanding of the many factors that potentially affect OSA pathophysiology.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2024.16352","type":"journal-article","created":{"date-parts":[[2024,6,24]],"date-time":"2024-06-24T15:03:02Z","timestamp":1719241382000},"page":"e2416352","source":"Crossref","is-referenced-by-count":5,"title":["Posttraumatic Stress Disorder and Obstructive Sleep Apnea in Twins"],"prefix":"10.1001","volume":"7","author":[{"given":"Amit J.","family":"Shah","sequence":"first","affiliation":[{"name":"Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta, Georgia"},{"name":"Department of Medicine, Emory University School of Medicine, Atlanta, Georgia"},{"name":"Atlanta Veterans Affairs Healthcare System, Decatur, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viola","family":"Vaccarino","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta, Georgia"},{"name":"Department of Medicine, Emory University School of Medicine, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack","family":"Goldberg","sequence":"additional","affiliation":[{"name":"Seattle Epidemiologic Research and Information Center, Office of Research and Development, Department of Veterans Affairs, Seattle, Washington"},{"name":"Department of Epidemiology, University of Washington, Seattle"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minxuan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Stanford University, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-An","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Bioinformatics, Rollins School of Public Health, Emory University, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Mailman School of Public Health, Columbia University, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oleksiy M.","family":"Levantsevych","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas L.","family":"Smith","sequence":"additional","affiliation":[{"name":"Seattle Epidemiologic Research and Information Center, Office of Research and Development, Department of Veterans Affairs, Seattle, Washington"},{"name":"Department of Epidemiology, University of Washington, Seattle"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikila","family":"Alagar","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iman","family":"Mousselli","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dayna A.","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gari D.","family":"Clifford","sequence":"additional","affiliation":[{"name":"Department of Biomedical Informatics, Emory University School of Medicine, Atlanta, Georgia"},{"name":"Wallace H.
