Studies were systematically screened for relevance and inclusion criteria by two reviewers before quality assessment and data extraction were performed. Fixed and random-effect meta-analyses were performed to evaluate PTSD as a risk factor for the development of specific autoimmune diseases. Subgroup analyses examining the roles of biological sex and PTSD severity were also performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The initial search yielded 3010 articles where only eight prospective and retrospective cohort studies met criteria for inclusion in the meta-analysis. These eight studies were subdivided based on specific disease outcomes. Random effects model for risk of developing any autoimmune disease in persons with PTSD vs. control was 1.291 (95% CI = 1.179 to 1.412; P &amp;lt;0.001; n=1,984,310; 4 studies included). The strength of the association between PTSD and risk of developing specific autoimmune diseases varied by outcome condition from 1.142 (95% CI = 1.085 to 1.202, P &amp;lt;0.001) for risk of IBD to 1.302 (1.037 to 1.635, P = 0.023) for risk of MS. Random effects models showed statistically significant associations between PTSD and IBD, SLE, RA, MS, and Thyroiditis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These results suggest that the risk for developing autoimmune conditions, including SLE, MS, RA, and IBD, is significantly increased in the setting of PTSD. This association may have important implications on clinical practice and research into the pathophysiology of stress
