Purpose: The purpose of this study was to develop and compare the prediction model for suicide attempts by Korean adolescents using logistic regression and decision tree analysis. Methods: This study utilized secondary data drawn from the 2019 Youth Health Risk Behavior web-based survey. A total of 20 items were selected as the explanatory variables (5 of sociodemographic characteristics, 10 of health-related behaviors, and 5 of psychosocial characteristics). For data analysis, descriptive statistics and logistic regression with complex samples and decision tree analysis were performed using IBM SPSS ver. 25.0 and Stata ver. 16.0. Results: A total of 1,731 participants (3.0%) out of 57,303 responded that they had attempted suicide. The most significant predictors of suicide attempts as determined using the logistic regression model were experience of sadness and hopelessness, substance abuse, and violent victimization. Girls who have experience of sadness and hopelessness, and experience of substance abuse have been identified as the most vulnerable group in suicide attempts in the decision tree model. Conclusion: Experiences of sadness and hopelessness, experiences of substance abuse, and experiences of violent victimization are the common major predictors of suicide attempts in both logistic regression and decision tree models, and the predict rates of both models were similar. We suggest to provide programs considering combination of high-risk predictors for adolescents to prevent suicide attempt.

Objectives: Adolescent suicide is a serious social problem. Adolescent alcohol use is one of the most important risk factors for adolescent suicide. This study aimed to identify the relationship between drinking habits and suicide among Korean adolescents. Methods: Data from the 14th and 15th Korean Youth Risk Behavior Web-based Survey, conducted in 2018 and 2019, were used for analysis. Multiple logistic regression analysis was used to identify the relationship between drinking habits-including the age of drinking initiation, frequency of drinking, average drinking amount, frequency of drunkenness-and suicidal ideation, plans, and attempts. Results: Even after adjusting for age, sex, school grade, academic achievement, socioeconomic status, depression, stress, and drinking habits, the frequencies of drinking and drunkenness increased the risk of suicide attempts. Suicide attempts were associated with the frequency of drinking in girls and middle school students, and with the frequency of drunkenness in boys and high school students. Conclusion: This study identified associations between drinking habits (the age of drinking initiation, frequency of drinking, average amount of drinking, frequency of drunkenness) and suicidal behavior in adolescents. Our findings suggest that to prevent adolescent suicide, it might be necessary to investigate drinking habits, including the frequencies of drinking and drunkenness. Moreover, considering the differences in sex and school grade, it is important to include the individual group characteristics when evaluating drinking habits.

The study thus examined and analyzed 1,478 people aged 65 or older in the Korea National Health and Nutrition Examination Survey of 2010 to investigate the effects of differences in the elderly's general characteristics and depression & suicide ideation and in their subjective health perceptions and quality of life on their depression and suicide ideation. As a result, Significant differences in their suicide ideation were also caused by such quality of life variables as ill in bed, exercise capacity, self-management, daily activity, pain and uncomfortableness, and anxiety. The logistic analysis results of depression and suicide ideation according to the degree of subjective health perception show a significant finding that the better health perception they had compared with their very poor subjective health perception, the lower the odds ratio became. In the category of quality of life, only experience of uncomfortableness caused significant results on suicide ideation and depression. The results of the study will be of great use as basic data to intervene in the suicide route of the elderly and take measures to prevent suicide.

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.

The purpose of this study was to investigate the risk factors of pregnancy and the relationship between pregnancy experience and suicidal behavior in 284 pregnancy experienced adolescents aged 13-19 years. The suicidal ideation was 57.8%, the suicide plan was 37.7% and the suicide attempt was 37.3% among female adolescents with pregnancy experience. By multivariate logistic regression analysis, female adolescents who experienced pregnancy had 1.44 times more suicidal ideation, 2.39 times more suicide plans, and 2.38 times more suicide attempts than those without suicidal thoughts, plans and attempts. Because of the high correlation between pregnancy experience and suicidal behavior in female adolescents, school and education authorities need systematic education and countermeasures to prevent adolescents' pregnancy and risk of suicide after pregnancy. And above all, convergent support and interest in home, school and community comprehensive area should be supported.

Background: This study aimed to demonstrate the importance to recognize subjective body image on their mental health on adolescents. Methods: We used the chi-square test and the multiple logistic regression model to analyze the data of the "Korean Youth Health Behavior Survey in 2018" (n=42,259) conducted by the Korea Centers for Disease Control and Prevention. Results: As a result of the analysis, suicide ideation increased when the subject body image is thin and fat. Especially, the suicide ideation who recognized the subjective body image as thin is higher (odds ratio [OR], 1.666; 95% confidence interval [CI], 1.050-1.295), and who recognized the subjective body image as fat is higher (OR, 1.134; 95% CI, 1.032-1.245) than the group who recognized the subjective body image as normal. Conclusion: When preparing a health policy on adolescent suicide issues, we need to consider the association between subjective body image and suicide ideation.

Purpose: By analyzing factors related to suicide ideation of Korean middle and high school students, the purpose of this study was to multi-dimensionally understand suicide ideation of Korean middle and high school students and arrange the plans to prevent suicide. Methods: This study used and analyzed the data on ‘The 3rd (Year2007) Korea Youth Health Risk Behavior Web-based Survey (KYHRBWS)' conducted by the Korea Centers for Disease Control and Prevention. In this study, we analyzed 74,698 respondents in total. SPSS 12.0 Program was used to analyze the survey. Descriptive statistics, Chi-Square Test and multivariate logistic regression were also used as research methods. Results: 23.8% of the Korean middle and high school students had suicide ideation during the last one year. Girls had higher possibility of suicide ideation by 1.51 times compared to boys. Students with poor academic achievement had more suicide ideation. In terms of health characteristics, students who perceived themselves as not healthy, and students with short weekday sleeping hours, more drinking experience and more smoking experience had more suicide ideation than others. Furthermore, students who perceived themselves as overweight or obese had more suicide ideation than other students. In terms of mental characteristics, students with high level of stress, low level of happiness and depression had more suicide ideation. Conclusion: As a result of this study, we found out that the factor that had the biggest influence on suicide ideation of Korean middle and high school students was depression. Consequently, active supports and policies to decrease suicide ideation of Korean middle and high school students are necessary. Therefore, active interviews, education for suicide prevention, and periodical screening inspection should be introduced in schools.

Background: Some mental illnesses such as depression are known to be one of the risk factors of suicide and proper antidepressant therapy can reduce suicidal behavior. Objectives: This study aimed to analyze regional variations in antidepressant consumption and adherence, suicide rate, prevalence of suicide related mental disorders, and access to relevant healthcare services. Methods: Cross-sectional analyses were conducted using National Patients Sample data compiled by the Health Insurance Review and Assessment Service between 2014 and 2016. We included patients who had a diagnosis record of suicide related mental disorders during the study period. Cause of death statistics and National health and medical statistics were used to identify suicide rate and distribution of healthcare service. We conducted visual analyses, chi-squared tests, independent t-tests and correlation analyses to demonstrate regional variations. Results: Between 2014 and 2016, the average prevalence of suicide related mental disorders was 5.4 per cent. Suicide rate and prevalence of suicide related mental disorders were higher in Gangwon, Chungcheong, and Jeolla (p < 0.001), and lower in Seoul (p < 0.001) than the national average. Unexpectedly, regional variations in antidepressant consumption were seen in the limited area including Daejeon, Chungnam and Gyeongnam (p < 0.05). The number of mild patient-centered clinics was associated positively with antidepressant consumption (p < 0.01) and associated negatively with suicide rate (p < 0.01). Conclusion: There were some regional variations in prevalence of suicide related mental disorders, antidepressant adherence and suicide rate. The higher level of antidepressant therapy and the lower level of suicide rates were seen in regions with easy access to mild patient-centered clinics.

Recently, rates of depression and suicide of adolescents in industrialized countries, including Korea, were rapidly increasing. Adolescent depression was often associated with anxiety disorder, eating disorder, attention deficits hyperactivity/disruptive behavior disorder. and suicidal attempts. Epidemiological data about depression and suicide of adolescents are reviewed. Psychological theories of depression and suicide are integrated in terms of a control theory interpretation. Issues about 'relationships between depression and anxiety' 'relationships between depression and suicide' 'the reason why rates of depression and suicide are rapidly increasing at adolescence' 'the reason why the different prevalence of depression between female and male is conspicuous at adolescence' and 'Korean culture associated with depression and suicide of adolescents' are discussed in terms of the revised control theory interpretation.

Objectives: The aim of this study was to assess the association between the use of heated tobacco products (HTP) and suicidal behaviors such as suicidal ideation, suicide planning, and suicide attempts among adolescents in South Korea. Methods: The study used a cross-sectional design. Data was from the 15th Korea Youth Risk Behavior Web-based Survey (KYRBS) performed in 2019 by the Ministry of Education, Ministry of Health and Welfare, and Korean Center for Disease Control and Prevention. Heated tobacco product use was used as a main independent variable and suicide-related behaviors such as suicidal ideation, planning, and attempts were applied as dependent variables. Out of 60,100 students, 57,303 responded. Results: HTP use significantly increased the odds of a suicide attempt and suicide planning among adolescents. After controlling for confounders, when comparing 'current HTP users' with 'never HTP users', the adjusted odds ratio (OR) was 1.78 (95% confidence interval (CI): 1.38-2.30) for suicide attempts among adolescents. After controlling the confounders, comparing 'current HTP users' with 'never HTP users', the adjusted OR was 1.36 (95% CI: 1.06-1.73) for suicide planning among adolescents. For sadness/despair among adolescents, when comparing 'current HTP users' with 'never HTP users', the adjusted OR was 1.29 (95% CI: 1.11-1.50). However, HTP use had no significant association with suicidal ideation among adolescents. Conclusions: Current HTP users were more likely to attempt to commit suicide, and more likely to plan to commit suicide than never HTP users among adolescents. These results may be useful in developing a scientific basis for designing suicide prevention programs targeting adolescents.
