This study aimed to evaluate incident psychiatric disorders in adults with HS compared with matched non-HS controls and to assess sex-specific risk. Methods: We conducted a retrospective propensity score\u2013matched cohort study using the TriNetX Global Collaborative Network. Adults with at least two HS diagnoses and no prior psychiatric diagnosis were compared with non-HS controls with repeated general health examination encounters and no psychiatric history. Time-to-event analyses estimated hazard ratios (HRs) with 95% confidence intervals (CIs). Sensitivity analyses used a 30-day lag and restriction to the most recent 5-year period. Results: After matching, 37,964 pairs were retained for the primary individual-outcome analysis. Median follow-up was shorter in the HS cohort than in matched controls (844 vs. 1505 days). HS was associated with increased risk of any psychiatric disorder (12.3% vs. 5.8%; HR 3.17, 95% CI 3.01\u20133.34) and severe psychiatric illness (0.6% vs. 0.1%; HR 6.70, 95% CI 4.77\u20139.41). Elevated risks were observed for bipolar\/manic disorders, personality disorders, substance use disorders, psychotic disorders, suicidal ideation, depression, eating disorders, anxiety, and insomnia\/parasomnia. Women had higher hazards of depression and anxiety, whereas men had higher hazards of substance use disorders; insomnia\/parasomnia showed a nominal association with higher hazard in men. Conclusions: In this observational EHR-based study, HS was associated with broad incident psychiatric morbidity. These findings support consideration of proactive mental health assessment and integrated dermatologic\u2013psychiatric care in patients with HS.<\/jats:p>","DOI":"10.3390\/jcm15134982","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T08:43:57Z","timestamp":1782463437000},"page":"4982","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Psychiatric Comorbidity in Hidradenitis Suppurativa\u2014A Large-Scale Retrospective Cohort Study"],"prefix":"10.3390","volume":"15","author":[{"given":"Beata","family":"Jastrz\u0105b-Mi\u015bkiewicz","sequence":"first","affiliation":[{"name":"Division of Dermatology, Venereology and Clinical Immunology, Faculty of Medicine, Wroclaw University of Science and Technology, 50-377 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0766-6342","authenticated-orcid":false,"given":"Jacek C.","family":"Szepietowski","sequence":"additional","affiliation":[{"name":"Division of Dermatology, Venereology and Clinical Immunology, Faculty of Medicine, Wroclaw University of Science and Technology, 50-377 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr K.","family":"Krajewski","sequence":"additional","affiliation":[{"name":"Division of Dermatology, Venereology and Clinical Immunology, Faculty of Medicine, Wroclaw University of Science and Technology, 50-377 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"462","DOI":"10.1016\/j.clindermatol.2025.05.007","article-title":"The Psychosocial Effects of Hidradenitis Suppurativa","volume":"43","author":"Mokos","year":"2025","journal-title":"Clin.
