Abstract: Background/Objectives: According to 2023 Ministry of Health and Welfare statistics, the suicide rate among adolescents aged 15 to 24 has steadily increased since 2018, from 3.7 to 5.5 per 100,000 populations, reaching a recent high. Although previous studies have pointed out that the risk of suicide in the future of those who had suffered from abuse was higher than that of the general population, seldom the researches focused on adolescent groups. Therefore, this aim of the study was exploring the risk of suicide after youth abuse and the impact of subsequent comorbid mental illness and suicide risk. Methods: This retrospective matched-cohort study analyzed data from the NHIRD covering the period from 2000 to 2015.A total of 976 cases aged 10-18 who had experienced abuse. Controlled group was conducted by 1:10 matching based on gender, age and time of medical treatment, and a control group who had no experienced violence was selected for comparison. We used the Cox proportional hazards model to analyze the risk of suicide among adolescents after exposure to violence. Results: The suicide rate among adolescents who have experienced violence was significantly higher than that of the control group after 15 years of follow-up (1.0% vs. 0.5%). The prevalence of mental illness or disorders in adolescents exposed to violence was significantly higher than in the control group (45.2% vs. 40.1%). Among adolescents who had experienced violence, the methods of suicide included poisoning (solid and liquid) (53.6% vs. 43.2%), hanging (1.2% vs. 0.6%), firearms (2.4% vs. 0%), and cutting instruments (27.4% vs. 22.8%), all of which were significantly higher than in the control group. After adjusting for gender, age, residential area, and mental health comorbidities, the risk of suicide in those who had experienced Abuse was 1.475 times that of the control group (95% CI = 1.125–1.933; P = 0.005). Conclusions: In this study, female gender, younger age, comorbid depression, and substance abuse were identified as risk factors for suicide among adolescent victims of violence. Exposure to youth violence was associated with an increased prevalence of emotional disorders, including depression and social isolation, which subsequently elevated the suicide risk. These findings underscore the urgent need for governmental attention to the mental health of adolescent victims of violence. Implementing targeted psychological support and intervention programs could play a crucial role in mitigating the risk of suicide among this vulnerable population.
