A suggested definition for sex as self-injury (SASI) is \u201ca pattern of seeking sexual situations involving psychological or physical harm to themselves.\u201d The research concerning SASI is sparse and the behavior is still in need of further understanding. The aim of this study was to investigate the prevalence of SASI among visitors to youth clinics in Sweden and the associations with sexual risk-taking, drug and alcohol consumption, and experience of violence. The study was based on data collected through the SEXual health Identification Tool (SEXIT) at youth clinics in multiple Swedish cities. A total of 813 participants were included in the study (Median\u2009=\u200919\u00a0years, SD 2.52\u00a0years, 734 identified as women, 78 as men, and 1 as other). Overall, 12.30% of the participants reported experience of SASI. SASI was most strongly associated with experience of sexual harassment or assault (OR 6.22), ever being diagnosed with a sexually transmitted infection (OR 3.07), drug use (OR 3.02), and experience of physical and\/or psychological violence (OR 2.78). In conclusion, SASI is occurring among youth clinic visitors and is associated with factors that endanger young people\u2019s physical and psychological well-being. Healthcare professionals need to have knowledge of SASI to offer proper help and support.<\/jats:p>","DOI":"10.1007\/s10508-025-03325-w","type":"journal-article","created":{"date-parts":[[2026,1,4]],"date-time":"2026-01-04T02:59:06Z","timestamp":1767495546000},"page":"109-117","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sex as Self-Injury Among Youth Clinic Visitors in Sweden"],"prefix":"10.1007","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-5807-1425","authenticated-orcid":false,"given":"Ellen","family":"Ek","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3772-6377","authenticated-orcid":false,"given":"Cecilia","family":"Fredlund","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9282-1142","authenticated-orcid":false,"given":"Sofia","family":"Hammarstr\u00f6m","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,1,4]]},"reference":[{"key":"3325_CR1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association.
