This study aims to identify the relationship between binge drinking experience (BDE) and suicide attempts in Korean adolescents. METHODS: The Ninth Korean Youth Risk Behavior Web-based Survey (KYRBS), conducted in 2013, was used for analysis. Multiple logistic regression analysis was used to identify the relationship between BDE and suicide attempts, and the relationship between BDE and suicide attempts in middle and high school students was stratified by age. RESULTS: BDE and suicide attempts were highly related. The odds ratio (OR) of attempted suicide in BDE was 1.63 times (95% confidence interval [CI], 1.28 to 2.09) higher then non-drinking in males. And the OR of attempted suicide in females was 1.21 times (95% CI, 1.07 to 1.37) higher then non-drinking in non-BDE, 1.79 times (95% CI, 1.47 to 2.19) higher in BDE. BDE was associated with suicide attempts in males aged 12 or 13 years (OR, 3.97; 95% CI, 1.57 to 10.03) and in females aged 15 years (OR, 2.66; 95% CI, 1.79 to 3.96). CONCLUSIONS: BDE is an important factor related to suicide attempts in adolescents. In order to reduce suicide attempts, it is necessary to educate the youth about the regulation of BDE and drinking prevention.

In addition, 11.2% of Korean adolescents in 2012 reported having thoughts about wanting to commit suicide at least once in the past year [1]. The rate of adolescent suicide attempts steadily increased from 2006 to 2013, 4.1% in 2013 and showed a declining trend to 2.9% from 2014 onwards [2]. Suicide attempts are in the middle of a continuum from suicidal ideation to suicide attempts and suicide [3]. People who enact suicidal behavior usually have suicide ideation, those who have suicidal ideation make suicide attempts, and a successful suicide attempt results in a completed suicide [4]. In order to prevent suicide attempts in adolescents, it is important to look at the current status of suicide attempts among adolescents, and it is also necessary to identify the factors affecting suicide attempts among adolescents. Although it has received less attention in Korean, foreign stud- www.e-epih.org | 1 Epidemiol Health 2018;40:e2018046 ies have highlighted binge drinking as a factor related to suicide attempts in adolescents [5,6]. Most adolescents have drinking experiences, and the number of adolescents exhibiting risky drinking behaviors, such as binge drinking or habitual drinking beyond the stage of drinking out of curiosity, is increasing among adolescents who drink alcohol [7]. From 2006 to 2012, the risky drinking rate in Korea was reported to be high, over 10.3% in males and over 8.0% in females [2]. Binge drinking in adolescents is very important as a starting point for problem behaviors, such as alcohol consumption or drinking behavior [8], and can easily lead to adverse outcomes such as addiction, serious health problems, injury, traffic accidents, and suicide [9,10]. In addition, binge drinking in adolescents has been reported to be associated with depression among psychiatric disorders, thereby affecting suicide attempts [5,11-13]. Adolescents with BDE were found to have mental health problems, including mood disorders and anxiety disorders. Regarding the relationship between alcohol consumption and suicidal behavior, drunkenness was found to increase the risk of suicide by about 90 times [14], and binge alcohol consumption was found to increase the risk of suicide by about 5 times compared with social drinking [15]. Recent studies regarding the relationship between drinking and suicide attempts as a factor for adolescent suicide have shown early alcohol use initiation as a risk factor for suicide attempts [16-18]. Compared to non-drinking or alcohol use initiation after the age of 13 years, there was a statistically significant association between early alcohol use initiation before the age of 13 years and suicide attempts among adolescents [18,19]. Early alcohol use initiation among adolescents was found to be a risk factor affecting suicide attempts [20]. There have been foreign studies regarding binge drinking, and binge drinking among young adolescents was found to be a risk factor for suicide attempts [6]. However, domestic studies on suicide attempts related to binge drinking among drinking behavior factors in adolescents are scarce. This study aims to investigate the relationship between BDE, known as risky drinking, and suicide attempts among Korean adolescents, stratified by age. This study aims to investigate the relationship between BDE and suicide attempts in Korean adolescents, to understand the factors for suicide attempts, and to use this as baseline data regarding adolescent binge drinking and for mental health promotion. The specific objectives are as follows: First, to investigate the relationship between non-drinking, non-BDE, and BDE and suicide attempts in adolescents. Second, to investigate the relationship between BDE and suicide attempts in adolescents, stratified by age.
