We examined STBs and their socioeconomic, psychosocial and clinical correlates in two communities in Cape Town.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We conducted psychiatric diagnostic interviews (MINI) at three public-sector facilities (2023-2024). Adults aged \u226518 years, with and without HIV, were recruited in a 2:1 ratio. We examined associations between suicidal ideation and sociodemographic factors, violence exposure, perceived stress, mental disorders, and HIV, reporting average marginal effects (AME) as percentage-point differences in predicted probability.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>We enrolled 613 participants (63.9% female; 65.4% living with HIV; median age 39). The prevalence of past 30-day suicidal ideation was 14.0%, while 22.2% reported a lifetime suicide attempt. Suicidal ideation was more likely among females (8.52 percentage points, 95% CI 3.08\u201313.96), those reporting violence in the community (7.52, 0.87\u201314.17) or in the family (14.09, 4.56 \u201323.62), those with moderate (7.76, 2.76 \u201312.77) or high perceived stress (33.58, 20.67\u2013 46.50), and those with depression (27.13, 14.67\u2013 39.58), post-traumatic stress disorder (27.98, 12.12 \u2013 43.84), or alcohol use disorder (8.34, 1.53 \u201315.15). Associations with high perceived stress and community violence persisted after adjustment for mental disorders. HIV status and other sociodemographic factors showed no evidence of association.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>STB prevalence was high in peri-urban communities in Cape Town and strongly associated with mental disorders, violence exposure, and perceived stress.
