Purpose: The suicide rate of adolescents in Korea is increasing annually. Therefore, this research was done to identify the suicide attempt rate of middle and high school students and to identify factors that influence suicidal attempts. Methods: The Korea Youth Health Risk Behavior Web-based Survey (2007) was used as data. Discriminant analysis and logistic regression were performed to analyze the data depending on gender to consider the gender difference in assessing the influence of each independent variable on suicidal attempts. Results: Discriminant analysis according on gender showed that 13 factors correlated with suicidal attempts for boys, and 20 factors for girls. The most highly correlated factors were smoking, depression and inhalation experience. For inhalation experience, boys had 2.7 times higher possibility of suicide attempts (95% CI 1.8-3.0) and girls, a 2.4 times higher possibility (95% CI 1.7-3.5). Conclusion: The results of the study indicate a need to classify adolescents for expectation of suicide risk and high danger for suicidal attempts through, and introduce suicide prevention programs for these adolescents. In particular, it is necessary to start intervention with students who smoke, have sexual and inhalation experiences and high levels of depression.

본 연구는 학교위험요인이 어떠한 경로 구조를 통하여 청소년의 자살생각에 영향을 미치는지를 Baumeister(1990)의 '도피이론(Escape Theory)' 모형에 기반하여 확인한 것이다. 이를 위해 '2008 경상북도청소년위기실태조사' 자료를 활용, 경북지역 중 고등학교 청소년 2,335명의 자료를 분석하였다. 분석결과, 학교위험요인 중 교사와의 관계위기는 청소년의 자살생각에 직접 영향을 미칠 뿐 아니라 부정적 자아존중감과 우울, 회피적 대처를 거쳐, 간접적으로도 영향을 미치는 것으로 나타났으며 특히 직접효과가 간접효과보다 더 큰 영향력을 발휘하여 교사와의 관계가 청소년의 자살생각에 중요한 변인임이 확인되었다. 반면 학교성적위기와 친구관계위기는 자살생각에 대한 직접 효과가 발견되지 않았으나 부정적 자아존중감과 우울, 회피적 대처 등의 변인을 거쳐 간접적으로 영향을 미치는 것으로 나타났다. 또한, 연령별로 중학생과 고등학생 집단 간에 이러한 경로에서의 차이는 보이지 않았다. 이상의 결과를 바탕으로 연구의 함의를 논의하였다.

Objectives : Epidemiological studies in other countries show that a low intake of omega-3 fatty acids (FAs) increases the risk of depression or suicidality. However, no studies have investigated the associations of suicidality with omega-3 FAs in Korea. Hence, this cross-sectional study aimed to investigate the effects of omega FAs on suicidality in the general South Korean population. Methods : The data in this study were sourced from adults (n=215,860) who completed the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI), and the associations between omega FAs and suicidality were analyzed using multivariate logistic regressions. Results : Our results demonstrated that high omega-3 FA intake was associated with a decreased risk of suicide (OR=0.83, 95% CI : 0.71-0.98) and the high omega-6 to omega-3 FA ratio was associated with an increased risk of suicide (OR=1.25, 95% CI : 1.02-1.54). Additionally, a high intake of omega-3 FAs was associated with a decreased risk of suicide in men, but not in women (OR=0.72, 95% CI : 0.59-0.88). Conclusions : Overall, our findings suggest that a lower intake of omega-3 FA is associated with the increased risk of suicidality in the general Korean population, especially in men.

Purpose: The purpose of this study is to develop a model for predicting mental health risk among adolescents based on health behavior information by employing a hybrid machine learning method. Methods: The study analyzed data of 51,850 domestic middle and high school students from 2022 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. Firstly, mental health risk levels (stress perception, suicidal thoughts, suicide attempts, suicide plans, experiences of sadness and despair, loneliness, and generalized anxiety disorder) were classified using the k-mean unsupervised learning technique. Secondly, demographic factors (family economic status, gender, age), academic performance, physical health (body mass index, moderate-intensity exercise, subjective health perception, oral health perception), daily life habits (sleep time, wake-up time, smartphone use time, difficulty recovering from fatigue), eating habits (consumption of high-caffeine drinks, sweet drinks, late-night snacks), violence victimization, and deviance (drinking, smoking experience) data were input to develop a random forest model predicting mental health risk, using logistic and XGBoosting. The model and its prediction performance were compared. Results: First, the subjects were classified into two mental health groups using k-mean unsupervised learning, with the high mental health risk group constituting 26.45% of the total sample (13,712 adolescents). This mental health risk group included most of the adolescents who had made suicide plans (95.1%) or attempted suicide (96.7%). Second, the predictive performance of the random forest model for classifying mental health risk groups significantly outperformed that of the reference model (AUC=.94). Predictors of high importance were 'difficulty recovering from daytime fatigue' and 'subjective health perception'. Conclusion: Based on an understanding of adolescent health behavior information, it is possible to predict the mental health risk levels of adolescents and make interventions in advance.

Objectives: The purpose of the present study was to explore the relationships between views on suicide, death, and life and lifetime suicidal attempts in the Korean context. Methods: Multiple logistic regression model was tested using data from Korean General Social Survey of 2009. We utilized the nationally representative survey data obtained via multistage stratified area probability sampling design from 1,599 respondents aged ${\geq}18$ years. Results: The proportion of lifetime suicidal attempts was 12.1% of entire sample in Korea. Some components of views on suicide and death influenced significantly on lifetime suicidal attempts after adjusting for demographic and health-related factors. The positive view on suicide(OR=0.76, 95% CI: 0.62-0.94), the naturalistic view on afterlife(OR=0.37, 95% CI: 0.67-0.99) and death concern(OR=0.67, 95% CI: 0.55-0.83) were risk factors of lifetime suicidal attempts. In contrast, the social responsibility view on suicide(OR=1.17, 95% CI: 1.00-1.37) and the transcendental view on afterlife(OR=1.25, 95% CI: 1.02-1.54) lowered the risk. Conclusions: Practical implications of the findings were discussed exploring policy evidences to screen high risk groups out and to reframe educational programs for suicide prevention. Strategic health messages need to be developed and transmitted for prevention of suicide.

Objectives : This study investigated factors related to suicide in high school students and focused on perceived academic performance. Methods : We surveyed 293 grade 10 high-school students in Jeju and Gyeonggi provinces and gave them self-assessment questionnaires. To evaluate the suicide risk, the questionnaire included questions about suicidal thoughts, plans, threats, deliberate self-injury, and suicide attempts from the Scale for Suicide Ideation (SSI). Also, it included the Beck Depression Inventory (BDI), Beck Hopelessness Scale (BHS), Locus of Control Scale (LOC), Rosenberg's Self Esteem Scale (RSE) and Perceived Academic Performance (PAP) to identify factors related to suicide in high school students. Results : Depression, hopelessness, and low self-esteem were related with suicidal thoughts, plans, attempts, and severe suicidal ideation (SSI score${geq}$16). In the multivariate analysis, a low level of PAP (OR=3.796, 95%CI 1.280-11.257) was significantly associated with severe suicidal ideation (SSI score${geq}$16). Deliberate self-injury was most prevalent in failing the PAP group and also having a high level of PAP (OR=6.161, 95%CI 1.474-25.760). Conclusion : The authors found that the suicide risk of high school students is related to depression, hopelessness, low self-esteem and a low level of PAP. These results provide significant indicators in planning an adolescent suicide prevention program.

The objective of this study is to evaluate the relationship of hopelessness and suicidal lethality of suicide attempters. The subjects were 72 persons who attempted suicide and came to the emergency room of Chungbuk National University Hospital from April 1st, 1995 to March 31st, 1996. The hopelessness of suicide attempter was assessed by Beck Hopelessness Scale(BHS), and the suicidal lethality was assessed by Risk-Rescue score. The Risk-Rescue Scores exhibited no significant differences in demographic characteristics (sex, age, education, religion, marital status, socioeconomic class, occupation) and psychiatric diagnoses. But the Risk-Rescue scores were significantly higher in high BHS group(BHS score ${\geq}$ 9) than in low BHS group(BHS score <9) and positive correlation was observed between the BHS and the Risk-Rescue score(Rs=0.77 : p<0.05). These results suggest that level of hopelessness be a major risk factor for suicidal lethality.

This study was conducted to evaluate a forecast model designed to describe a vocational high school for runaway students. The study included 2000 adolescents from the KEEP(Korean Education and Employment Panel). A Data mining decision tree model revealed that: (1) Suicide ideation was a risk factor for running away among smokers. (2) High self-evaluation was a risk factor for running away among individuals that smoked and had no suicide ideation. (3) Drinking was predicted as a risk factor for no smokers, while family life dissatisfaction was predicted as a risk factor among non-smokers that drank. (4) Negative relationship with mother was predicted as a risk factor among non-drinking non-smoking.

Objectives: There is higher rates of experience of suicide ideation and suicide attempt of adolescents in the Lima and Callao region compared with the results of the epidemiological study (2013) conducted by Peru National Institute of Mental Health and the Global School-based Student Health Survey (2010) which is was conducted among adolescents across all regions of Peru. Based on the PRECEDE model, this study analyzed the prevalence and the factor associated with the suicide attempt among the adolescent in a poor urban area in Peru. Methods: A stratified random sampling was used for the survey to select study participants from the 6 secondary schools based in Comas or Callao. The survey was conducted November 25th and December 4th in 2015 and a total of 738 individuals included in the analysis. In order to analyze factors influencing suicide attempt, comparison of predisposing factor, reinforcing factor, enabling factor, behavioral factor, environmental factor, psychological factors by suicide attempt and suicide risk group were identified through the chi-square test and hierarchical logistic regression. Results: Results showed that those who reported having less parental understanding, less time spent with parents, and 'almost none/none' for parental affection had more experience of suicide attempt and were more likely to sort into the high suicide risk group. Also, a greater proportion of those with the experience of suicide attempt had more experience of smoking and alcohol consumption, and experience of physical abuse and feeling insulted and depression in comparison to that of those without experience of suicide attempt. Variables that had a significant effect on suicide attempt included depression, subjective happiness, smoking experience, sexual intercourse, involvement in fight, parental affection, and gender (male). Conclusions: The results of the current study can serve as grounds for the necessity of acknowledging that adolescent suicide does not simply depend on a couple of factors, but arises from situations in which individual, home, school, social factors influence one another, and therefore adolescent suicide should be prevented and addressed through a multi-dimensional and integrated approach.

Objectives : The purpose of this study was to evaluate community mental health professionals and hospital workers attitude and awareness towards suicide. Methods : This study investigated 264 community mental health professionals and 228 hospital workers. SOQs (Suicidal Opinion Questionnaires) were used from July 2007 to September 2007. After a factor analysis for the attitude towards suicide, the items on ethics, mental illness, religion, risk, and motivation were included in the subsequent analysis. Results : There were significant differences in the attitude towards suicide according to religion, age, educational background, the marriage status, the economic position, and different professional licenses. Hospital workers' view was different from the community workers'. The hospital workers judged that suicide was due to mental illness, and suicide was high for the people in a special environment and who lacked motivation, which caused them to fall in a dangerous situation. For the lower educational group, they thought that suicide was attributable to mental illness. The awareness for suicide was significantly higher in the group with a postgraduate education, unmarried people, mental health professionals and the persons who had concern and experience with suicide. The factors that had an influence on the awareness of suicide were the items of mental illness, religion, risk and motivational factors. Conclusions : This study suggested that the factors to increase the awareness and attitude for suicide were the experience of increased education and case management of suicide. Therefore, education dealing with suicide and reinforcement of crisis management programs should be developed.
