응급실에 내원한 자살 시도자의 특성과 반복 자살 시도에 영향을 미치는 요인 = Characteristics of Suicide Attempters Admitted to the Emergency Room and Factors Related to Repetitive Suicide Attempts

다국어 초록 (Multilingual Abstract)

Objectives：Suicide attempt history is one of the major suicide risk factors and the suicide mortality rate increases with the number of suicide attempts. This study aimed to compare demographic and clinical factors between first and multiple suicide attempters and investigate risk factors for multiple suicide attempts. Methods：Participants were 537 patients who were admitted to an emergency room after attempting suicide and divided into two groups (393 first attempters and 144 multiple attempters). Demographic factors, clinical characteristics, and suicide-related characteristics were compared between the two groups. Variables with a p-value lower than 0.1 were included in a multivariate logistic regression analysis. Logistic regression models were considered to identify independent risk factors for multiple suicide attempts. The significance level was set to 0.05. Results：Among demographic factors, the two groups differed in age, sex, education, occupation, and marital and cohabitation status. Multiple attempters were more likely to have a mental disorder, current use of psychiatric medication, interpersonal and psychiatric motivation for suicide, current suicidal thoughts, help seeking behavior, awareness of suicide, and agreement with psychiatric follow up. In the regression analysis, unmarried status, mental disorder, interpersonal or psychiatric stress, help seeking behavior, and antidepressant use emerged as significant risk factors of multiple suicide attempts. Conclusion：The study’s findings suggested that there are differences in the demographic and clinical characteristics of first and multiple suicide attempters. Specific strategies that consider unmarried status, mental disorder, interpersonal or psychiatric stress, help seeking behavior, and antidepressant use may be valuable for future suicide prevention.
