Objectives: Among the Korean elderly (those 65 years of age and older), the suicide rate is 80.3/100 000 people, which is ten times higher than the Organization for Economic Cooperation and Development average. Because South Korea is rapidly becoming an aging population, this high elderly suicidal rate will only get worse. Although the size of the elderly suicide problem is quite large, previous research in South Korea has surveyed restricted areas and not the entire country. Even though the factors that affect elderly suicide are complicated, there has been little research into these influencing factors. Thus, this research uses the national survey data (Community Health Survey) that was obtained in 2009. Additionally, we analyze factors affecting elderly suicidal ideation and attempts as well as the paths of these effects. Methods: Community Health Survey data obtained by the Korea Centers for Disease Control and Prevention in 2009 was used for this study. We additionally examined the factors that affect suicide with chi-squared tests, t-tests, Pearson's correlation test, and path analysis. Results: Depressive symptoms and suicidal ideation are the only factors that directly affect suicidal attempts. Demographic, behavioral, and physical activity factors have indirect effects on suicidal attempts. Conclusions: Depression has the strongest influence on suicidal ideation and attempts. Demographic, behavioral, and physical activity factors affect suicidal attempts mostly through depressive symptoms. In addition, there is a path that suggests that demographic, behavioral, and physical activity factors affect suicidal attempts not through depression symptoms but only through suicidal ideation. This means that the elderly who do not have depression symptoms attempt suicide according to their own situations and characteristics.

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.

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.

Objectives : The objective of this study was to identify the risky behavior subtypes in adolescents with depression, and the relationship between those subtypes and suicide attempt. Methods : Ninety adolescents who met the Diagnostic and Statistical Manual of Mental Disorders-4th edition criteria for major depressive disorder, dysthymia, or depressive disorder not otherwise specified participated in the study. Participants were interviewed about suicidal attempts, non-suicidal self-injuries. Smoking, drinking behaviors, and searching for the word "suicide" on the internet, negative life events including bulling-bullied experiences, and history of abuse were also included with questionnaires. Results : The results of cluster analysis showed that four risky behaviors were divided into three clusters : non-risky type, characterized by few risky behaviors ; delinquency type, which was characterized by smoking and drinking ; non-suicidal self-injury type. In non-suicidal self-injury type, percentage of girls was higher and clinical symptoms were more severe than delinquency type. In addition, delinquency type members could be a bully, while non-suicidal self-injury type members could be abused by a family member. Logistic regression analysis showed that both risky behavior subtypes were significant predictors of suicide attempt. Conclusion : These results suggest that two types of risky behaviors of depressed adolescents have an effect on the suicide attempts independently. Then, the implications and limitations of the study were discussed and directions for future studies were suggested.

Objectives : This study aimed to compare the characteristics of suicide attempts among Korean patients with mixed and non-mixed depression. Methods : Patients who visited the emergency room due to a suicide attempt and participated in the Korean Cohort for the Model Predicting a Suicide and Suicide-related Behavior study were included. Using the Montgomery-Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS), 111 patients were classified into the mixed depression (n=46) and non-mixed depression groups (n=65). The Koukopoulos Mixed Depression Rating Scale (KMDRS) score was calculated using the MADRS and YMRS scores. Suicide attempt characteristics were evaluated using the Columbia Suicidal Severity Rating Scale (C-SSRS) and Suicide Intent Scale (SIS). Results : In the mixed depression group, the reason item among the ideation intensity score of the C-SSRS was higher, and the deterrent item score was lower. Scores on the timing and suicide note items of the SIS were higher, and scores for overt communication items were lower in the mixed depression group. The KMDRS score was positively correlated with the C-SSRS ideation intensity and total SIS score. After adjusting for additional variables, the KMDRS scores had a significant effect on the C-SSRS ideation intensity and total SIS scores. Conclusions : The mixed depression group showed a difference in the intensity of suicidal ideation and suicidal intention compared to those in the non-mixed depression group. The overall suicidal ideation intensity and suicidal intention increased according to the degree of mixed depression.

Purpose: The purpose of this study is to explore influencing factors which contribute to the suicidal ideation in community residents who have ever experienced suicidal attempts. Methods: The subjects of this study were a total of 165 local residents with some experiences of suicidal attempts in B City and K Province. The data were collected from May 1st to October 30th, 2012 and self-report questionnaires including Suicidal Ideation Inventory, Self-Esteem Inventory, Depression, Family and Social Support Inventory were used as a measurement tool. The data were analyzed using t-test, ANOVA, Pearson correlation coefficients, multiple regression with the SPSS/WIN 18.0 program. Results: The average score of suicidal ideation in the local residents with experiences of suicidal attempts was $12.7{\pm}6.25$. Predicted factors on suicidal ideation in the local residents with experiences of suicide attempts included self-esteem, depression and physical illness, and the suicidal ideation has a variance explanation power of 54%. Conclusion: The development and application of intervention programs, which can help to increase self-esteem levels and decrease depression levels among community residents with experiences of suicidal attempts, are first needed. Furthermore, nursing services of customized self-management for people with physical disabilities are needed on the basis of their own physical problems.

Purpose: The purpose of this study is to measure suicidal ideation and to investigate the affecting factors in male baby boomers using Korea Health Panel Data 2011. Methods: The Korea Health Panel Data 2011 were collected from June to December 2011 by Korea Institute for Health and Social Affairs and National Health Insurance Corporation and included 908 people who responded to the question regarding suicidal ideation. The data were analyzed by chi-square and multiple logistic regression using SPSS WIN 20.0 program. Results: The ratio of suicidal ideation was 6.1% in male baby boomers. Affecting factors of suicidal ideation in male baby boomers showed that presence of depression, frustrating experience, and regular diet had more suicidal ideation by 10.90 times (CI 5.14-23.18), 7.78 times (CI 1.98-30.51), 3.38 times (CI 1.65-6.90), respectively. Conclusion: This study is meaningful as an attempt to measure suicidal ideation and to analyze affecting factors with suicidal ideation in male baby boomers. Further study including careful and thorough examination may be needed.
