We aimed togenerate pooled prevalence estimates, and examine variation in mental disorders,suicidality, and non-suicidal selfinjury (NSSI) among trans adults globally. Weconducted a systematic review and meta-analysis of studies reporting current orlifetime prevalence of mental disorders, assessed using symptom screeninginstruments with validated general-population thresholds or clinical diagnoses,alongside self-reported suicidality and NSSI. MEDLINE, Embase, and PsycINFO weresearched from January 1, 1990-April 7, 2026. Restricted or highly selectedsubpopulations were excluded, except for gender-affirming clinic samples. Estimateswere calculated overall and by gender identity. Subgroup\/meta-regression analysesexamined variation by study and sociodemographic characteristics. We identified 207studies with 134,071 trans participants across 52 countries. Pooled prevalenceestimates, combining symptoms exceeding screening thresholds and clinicallydiagnosed disorders, were 40.1% (95% CI 35.6-44.8) for depression, 29.8% (20.3-40.2) for anxiety, and 23.6% (14.9-33.5) for post-traumatic stress disorder. Past-12-month prevalence was 43.1% (38.9-47.3) for suicidal ideation, 9.3%(7.7-11.0) forsuicide attempts, and 26.1% (20.4-32.2) for NSSI. Limited data suggested higherprevalences among non-binary participants. Prevalence estimates varied significantlyby assessment method, recruitment setting, and geographic region. Trans peopleexperience a substantial burden of mental disorders, suicidality, and NSSI. Elevatedprevalence relative to general population comparator estimates indicates a need for affirming, accessible mental healthcare and improved approaches to assessing andinterpreting mental health outcomes in trans populations.<\/jats:p>","DOI":"10.1017\/s0033291726106254","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T11:58:36Z","timestamp":1791460716000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of mental health outcomes among trans and gender diverse adults: a global systematic review and meta-analysis"],"prefix":"10.1017","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7928-4541","authenticated-orcid":false,"given":"Emily Rose","family":"Symes","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"},{"name":"Royal Prince Alfred Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr","given":"Thomas","family":"Santo","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Sutherland","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3484-6520","authenticated-orcid":false,"given":"Michelle","family":"Lynch","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4676-3233","authenticated-orcid":false,"given":"Sophia","family":"Taylor","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4101-0634","authenticated-orcid":false,"given":"Patrick","family":"Lewis","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8513-2218","authenticated-orcid":false,"given":"Louisa","family":"Degenhardt","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0144fat78","id-type":"ROR","asserted-by":"publisher"}],"name":"National Drug and Alcohol Research Centre"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,10,8]]},"reference":[{"key":"S0033291726106254_r5","doi-asserted-by":"publisher","DOI":"10.4088\/JCP.08m04967blu"},{"key":"S0033291726106254_r27","doi-asserted-by":"publisher","DOI":"10.1037\/sgd0000621"},{"key":"S0033291726106254_r13","doi-asserted-by":"publisher","DOI":"10.3390\/brainsci12030366"},{"key":"S0033291726106254_r22","unstructured":"Grant, J.
