Objective The study aimed to describe the frequency and associations of the number of medical visits for the violent victimization and mental health problems in adolescents in South Korea. Methods In 2017, 62,276 middle and high school students participated in the thirteenth Korea Youth Risk Behavior Web-based Survey (KYRBS). The frequency of violence victimization during the last 12 months was measured. The collected data were analyzed by applying descriptive statistics, chi-square tests, multiple linear regression, and logistic regression analysis, using the SPSS 22.0. The data were weighted to generate national estimates. Results Among the respondents (sample size=62,276, weighted=3,027,488), 3.7% of boys and 1.7% of girls had experienced being treated by a doctor due to violence during the recent past 12 months. In multiple linear regression analysis, feelings of sadness or hopeless, suicide ideation, suicide plan, suicide attempt were positively associated with violence victimization (F=32656.037, p<0.001) dose response. Conclusion The results found cross-sectional evidence that violence victimization was associated with higher suicide behavior and depressed mood. The victims of violence should be referred follow-up for physical and psychological issues. Also, a policy including the first responders and medical staffs should be initiated.
