Suicide has been a long-standing problem for global public health, along with almost 800,000 deaths from suicide worldwide in 2016, accounting for 1.4% of all deaths. South Korea was ranked first in suicide mortality in 2018 among countries in the Organization for Economic Cooperation and Development. This study aimed to suggest up-to-date information about suicide-related indicators such as the rate of suicidal ideation, suicide attempt, and suicide death, and its trends by applying sampling weight to make it nationally representative. In this study, we used the data sources: Korea National Health and Nutrition Examination (KNHANES, '07-13, '15-18), Korean Community Health Survey (KCHS, '08-09, '13, '17), Korean Wealth Panel Study (KOWEPS, '12-18), Korea Health Panel Survey (KHP, '10-13), and Statistics Korea (1983-2017). The rate of suicidal ideation as recent year was 4.73% (KNHANES, '17), 6.96% (KCHS, '17), 2.29% (KOWEPS, '18), and 5.39% (KHP, '13). That of suicide attempt as recent year was 0.51% (KNHANES, '18), 0.32% (KCHS, '17), and 0.15% (KOWEPS, '18). Annual percentage change (APC) of suicidal ideation was -15.4% (KNHANES, '07-13, '15, '17), -2.5% (KCHS, '08-09, '13, '17), -10.8% (KOWEPS, '12-18), and -10.9% (KHP, '10-13). APC of suicide attempt was -4.4% (KNHANES, '07-13, '15-18), -4.4% (KCHS, '08-09, '13, '17), and -13.6% (KOWEPS, '12-18). APC of death by intentional self-harm was -1.25% (Statistics Korea, '07-18). All suicide-related indicators were found to be decreasing in the overall from 2009. Individuals with lower income level were more likely to experience suicidal ideation and suicide attempts. Even though suicide rate had been continuously decreasing from its highest point in 2011 (suicide rate: 31.7 per 100,000 population) to 2017 (suicide rate: 24.3 per 100,000 population), it increased again in 2018 (suicide rate: 26.6 per 100,000 population). This information would be grounded on policy implementation for suicide prevention, thus continuous data observation is necessary.

The purpose of this study was to identify the rate of suicidal attempts, investigate difference of rate of suicidal attempts between students and delinquents, and examine correlation between personality, family dynamics, environment, and suicidal attempts among Korean adolescents. Method: Data were collected through questionnaire surveys. Internal consistencies for this questionnaire ranged from 0.63 to 0.88. The subject used in this study consisted of 922(delinquent : 367, student : 555), using the proportional stratified random sampling method. Statistical methods employed were Chi-square and t-test. Results: \circled1 The rate of suicidal attempts were 10.8%, and the highest peak age of suicidal attempt was 17-18 year old (16.9%). \circled2 Delinquents(19.6%) showed a higher rate of suicidal attempts than students (5.1%). Among the students, girls (43.3%) showed a higher rate of suicidal attempt than boys (19.1%). Whereas, boys (80.9%) showed a higher rate of suicidal attempt than girls (56.7%) among delinquents. \circled3 Those who attempt suicide have more familial problem such as incest, psychosis, depression, attempted suicide, committed suicide, and alcoholism in their family. They also have more dysfunctional family dynamics, environment, and maladaptive personalities than non-attempters. Conclusions: Suicide and suicidal behaviors are multifaceted events. For suicide prevention, independent assessments of variables such as familial problems, personality, family dynamics, and environment must be considered.

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.

Purpose: The study was performed to identify factors influencing suicidal ideation in patients with chronic mental health problems and who live in the community. Methods: Data were collected using questionnaires and participants were 140 people with mental illness living in Y-si, Gyeonggi-do. The study was carried out from May 15 to September 30, 2014. Data were analyzed using descriptive statistics, Pearson Correlation Coefficients, and Logistic Regression with the SPSS/WIN 18.0 statistical program. Results: The number of persons who attempted suicide was 47(33.6%) and the number who had suicide ideation was 22(15.7%). The mean score for depression was $6.4{\pm}6.45$. The mean score for life satisfaction was $16.5{\pm}8.21$. Depression had a significant negative correlation with life satisfaction. Odds ratio of suicide ideation was 1.19. The significant factor influencing suicidal ideation was depression. Conclusion: The results of this study can be used in the development and practice of programs to decrease suicide in people with mental illness.

Purpose: This study was done to explore the relationship of social support and meaning of life to suicidal thoughts among patients with cancer. Methods: Data were collected by questionnaires from 138 patients who had been in cancer treatment at medical clinics and 8 patients who were members of an internet cancer association. The data were collected between August and November 2009 and analyzed using SPSS 12.0. Results: Of the participants, 47.3% reported having had suicidal thoughts and 16.4% had attempted suicide since the diagnosis of cancer. The study participants received most support from family members, but 73.3% reported experiencing an existential vacuum. The suicide attempt group had significantly higher scores according to gender, age, level of education, diagnosis, treatment modality, level of activity, caregiver and social support compare to the suicide thought group. Suicidal thoughts were negatively related to social support and meaning of life was positively associated with social support. Support from family and friends and diagnosis explained 50.0% of variance for suicidal thoughts with 36.0% of variance being explained by family support. Conclusion: Nurses should be able to identify risk factors for suicide in cancer patients. Prevention and intervention efforts need to be directed toward improving social support, family support in particular, and assisting patients finding meaning in life after a diagnosis of cancer.

Objectives: This study attempted to determine the influence of factors related to suicide attempts in the elderly. Data from a 2017 Community Health Survey were used to find 67,810 subjects aged 65 years or older. Methods: Cross-analysis and logistic regression analysis were conducted by dividing the suicide thought and suicide attempt experience groups. Results: In the group with subjective stress, suicidal thoughts were higher in women 2.748 times (p<0.01) and 1.917 times (p<0.001) in women. In terms of income level, the higher the income level, the lower the suicidal ideation experience. Suicide attempts were 0.708 times lower when mastication was not uncomfortable and 0.170 times lower when the patient was not experiencing depression (p<0.001). Conclusions: The correlation between oral dysfunction and suicidal thoughts and attempts in the elderly has been demonstrated, and it is expected to be used as baseline data for establishing an institutional study.

The purpose of this study is to examine the difference in the mediating effects of relief from fatigue through sleep and perceived subjective health in the relationship between perceived stress and subjective happiness in middle school students who attempted suicide. The analysis was conducted using Path analysis, the Bootstrapping method, Phantom variable and Multiple group analysis by AMOSS using the IBM SPSS 23 and IBM SPSS AMOS 23 programs with 820 middle school students who attempted suicide in the past 12 months using the raw data of the Korea Risk Behavior Web-Based Survey (2016). In the relationship between perceived stress and perceived subjective health, the indirect effect of relief from fatigue through sleep and perceived subjective health (${\beta}=-.12$, p=.003) was statistically significant. The difference in the magnitude of the two indirect effects was found to be greater for the subjective health status than for relief from fatigue through sleep (difference = .02, p=.028) and the effects were greater for the males (${\beta}=.44$, p <.001) than for the females (${\beta}=.23$, p<.001). Based on the findings, it is necessary to develop and apply an educational program that includes the factors that contribute to improving the happiness of middle school students.

Objectives: The purpose of this study was to investigate the association between suicidal behavior and patterns of alcohol consumption in Korean adults. Methods: This study was based on data provided by the Korea National Health and Nutritional Examination Survey from 2007 to 2011. A total of 42 347 subjects were included in the study, of whom 19 292 were male and 23 055 were female. Logistic regression analysis was performed to assess the association between patterns of alcohol consumption and suicidal behavior. Results: Among the study subjects, 1426 males (11.3%) and 3599 females (21.2%) had experienced suicidal ideation, and 106 males (0.8%) and 190 females (1.1%) had attempted suicide during the previous 12 months. Alcohol Use Disorders Identification Test (AU-DIT) scores were found to be associated with suicidal ideation in males and associated with both suicidal ideation and suicide attempts in females. Alcoholic blackouts were associated with suicidal ideation and suicide attempts in males, and were also associated with suicidal ideation in females. Conclusions: In this study, we found that certain patterns of alcohol consumption were associated with suicidal behaviors. In particular, only alcoholic blackouts and categorized AUDIT scores were found to be associated with suicidal behavior in males. We therefore suggest that further research is needed to examine this relationship prospectively and in other settings.

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.
