Although the effect of psychological conditions on LBP is regularly studied, there is little published to date investigating nightmare disorder (NMD) and LBP. The purpose of this study was to (1) investigate whether an association exists between NMD and LBP and (2) estimate the effect of NMD diagnosis on time to LBP. We used a retrospective cohort design with oversampling of those with NMD from the Veterans Health Administration (n = 15 983). We used logistic regression to assess for a cross-sectional association between NMD and LBP and survival analysis to estimate the effect of NMD on time to LBP, up to 60-month follow-up, conditioning on age, sex, race, index year, Charlson Comorbidity Index, depression, anxiety, insomnia, combat exposure, and prisoner of war history to address confounding. Odds ratios (with 95% confidence intervals [CIs]) indicated a cross-sectional association of 1.35 (1.13 to 1.60) and 1.21 (1.02 to 1.42) for NMD and LBP within 6 months and 12 months pre- or post-NMD diagnosis, respectively. Hazard ratios (HRs) indicated the effect of NMD on time to LBP that was time-dependent\u2014HR (with 95% CIs) 1.27 (1.02 to 1.59), 1.23 (1.03 to 1.48), 1.19 (1.01 to 1.40), and 1.10 (0.94 to 1.29) in the first 3, 6, 9, and 12 months post-diagnosis, respectively\u2014approximating the null (1.00) at &amp;gt;12 months. The estimated effect of NMD on LBP suggests that improved screening for NMD among veterans may help clinicians and researchers predict (or intervene to reduce) risk of future back pain.<\/jats:p>","DOI":"10.1093\/sleepadvances\/zpac030","type":"journal-article","created":{"date-parts":[[2022,9,10]],"date-time":"2022-09-10T16:08:31Z","timestamp":1662826111000},"source":"Crossref","is-referenced-by-count":2,"title":["Nightmare disorder and low back pain in veterans: cross-sectional association and effect over time"],"prefix":"10.1093","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3205-9280","authenticated-orcid":false,"given":"Kenneth A","family":"Taylor","sequence":"first","affiliation":[{"name":"Orthopaedic Surgery, Duke University School of Medicine , Durham, NC , USA"},{"name":"Duke Clinical Research Institute, Duke University School of Medicine , Durham, NC , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Skai W","family":"Schwartz","sequence":"additional","affiliation":[{"name":"College of Public Health, University of South Florida , Tampa, FL , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3609-2595","authenticated-orcid":false,"given":"Amy C","family":"Alman","sequence":"additional","affiliation":[{"name":"College of Public Health, University of South Florida , Tampa, FL , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam P","family":"Goode","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery, Duke University School of Medicine , Durham, NC , USA"},{"name":"Duke Clinical Research Institute, Duke University School of Medicine , Durham, NC , USA"},{"name":"Population Health Sciences, Duke University School of Medicine , Durham, NC , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Getachew A","family":"Dagne","sequence":"additional","affiliation":[{"name":"College of Public Health, University of South Florida , Tampa, FL , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuri V","family":"Sebasti\u00e3o","sequence":"additional","affiliation":[{"name":"Division of Global Women\u2019s Health, Department of Obstetrics and Gynecology, School of Medicine, University of North Carolina at Chapel Hill , Chapel Hill, NC , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip R","family":"Foulis","sequence":"additional","affiliation":[{"name":"Morsani College of Medicine, University of South Florida , Tampa, FL , USA"},{"name":"Pathology and Laboratory Medicine, James A.
