Objectives: The study aimed to analyze the effects of household financial difficulties caused by COVID-19 (2019 coronavirus disease) on suicidal tendencies of adolescents. Methods: We selected 54,948 middle and high school students who were surveyed based on the Korean Youth Risk Behavior Web-based Survey 2020. To analyze the data, we used the STATA 16.0 program to conduct propensity score matching (PSM). Results: After controlling for selection effects by using PSM, the household financial difficulties caused by COVID-19 maintained a significant predictive effect on increasing suicidal ideation, suicide attempts, and decreasing tendency in hospital-treated after suicide attempts. However, depressive symptoms and suicide plan did not show a significant correlation with household financial difficulties associated with COVID-19. Conclusions: It was found that the rate of suicidal ideation and suicide attempts among adolescents who experienced a household financial difficulties due to COVID-19. Therefore, It can provide empirical evidence for estimating the impact of COVID-19 on adolescent suicide rates.

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.

Purpose: This study explored the influencing factors on suicide-related behaviors (ideation, plans, and attempts) focusing on mental health problems (anxiety, depression, and loneliness) among Korean adolescents. Methods: A secondary analysis was conducted with data from the 16th Korean Youth Health Behavior Survey collected from in 2020 by the Korea Centers for Disease Control and Prevention. Chi-square tests and multivariate logistic regression analyses were performed. Results: After the adjustment of demographic characteristics and health risk behaviors, the influences of mental health problems on suicidal ideation, plans, and attempts showed the anxiety odds ratio (OR) for severe anxiety vs. minimal (OR 4.65, 4.67, and 3.75), depression (OR 4.27, 3.69, and 4.49), loneliness (OR 2.18, 1.96, and 1.96). Health risk behaviors (violence experience, drug use, stress, smoking, and drinking alcohol) and demographic variables (gender, school record, and socioeconomic status) were also significantly associated with suicide-related behaviors. Conclusion: Anxiety, depression, and loneliness were strong predictors of suicide-related behaviors. Early detection of suicide risks through screening for comprehensive mental health problems was recommended. Suicide prevention that considers the risk factors, including mental health problems and other risk factors, needs to be developed and implemented to reduce suicide risks among adolescents.

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 aim of this study was updating suicide-related indicators, including the number of suicidal deaths, suicide rate, and the prevalence of suicidal ideation and suicide attempts. We observed trends in suicide-related indicators based on up-to-date information. This study used five data sources to evaluate the trends of suicide-related indicators: Statistics Korea (1983-2020), Korean Wealth Panel Study (KOWEPS, 2012-2020), and Korea Health Panel Survey (KHP, 2010-2013, 2016-2018), Korean National Health and Nutrition Examination (KNHANES, 2007-2013, 2015-2020), and Korean Community Health Survey (KCHS, 2008-2009, 2013, 2017). The suicide rate per 100,000 population decrease from 26.9 in 2019 to 25.7 in 2020. Based on recently available data, the rates of suicidal ideation were 1.48% (KOWEPS, 2020), 2.61% (KHP, 2018), 4.62% (KNHANES, 2019), and 6.96% (KCHS, 2017). Those of suicide attempt as were 0.07% (KOWEPS, 2020), 0.44% (KNHANES, 2020), and 0.32% (KCHS, 2017). Annual percentage change (APC) of suicide rate was -1.87% (Statistics Korea, 2011-2020). APC of suicidal ideation was -10.7% (KOWEPS, 2012-2020), -11.5% (KHP, 2010-2013, 2016-2018), -14.7% (KNHANES, 2007-2013, 2015, 2017, 2019), and -2.5% (KCHS, 2008-2009, 2013, 2017). APC of suicide attempt was -11.3% (KOWEPS, 2012-2019), -5.2% (KNHANES, 2007-2013, 2015-2020), and -4.4% (KCHS, 2008-2009, 2013, 2017). Although the suicide rate in Korea has decreased compared to 10 years ago, it is still at a high level. Thus, continuous observation and appropriate suicide prevention policies are needed.

Purpose: Suicide ranks among the top causes of death among youth in South Korea. This study aimed to identify the characteristics of suicidal individuals treated at emergency departments between 2011 and 2020. Methods: A retrospective analysis was conducted using data from January 2011 to December 2020 in the Injury Surveillance Cohort, a prospective registry. Patients' sex, age, mortality, methods of self-harm, and previous suicide attempts were analyzed. The methods of self-harm were categorized into falls, asphyxiation, blunt injuries, penetrating injuries, poisoning, and others. Sub-groups with and without poisoning were compared. Results: The proportion of self-harm/suicide attempts increased from 2.3% (2011) to 5.0% (2020). The mortality rate decreased from 10.8% (2011) to 6.3% (2020). Poisoning was the most common method (61.7%). Mortality rates ranged from 42.0% for asphyxiation to 0.2% for blunt injuries. Individuals in their 20s showed a marked increase in suicide/self-harm attempts, especially in the last three years. A large proportion of decedents in their 70s or older (52.6%) used poisoning as a method of suicide. The percentage of individuals with two or more previous attempts rose from 7.1% (2011) to 19.7% (2020). The death rates by poisoning decreased from 7.7% (2011) to 2.5% (2020). Conclusion: Our findings underscore the urgent need for targeted interventions and suicide prevention policies. Managing and reducing suicide and self-harm in emergency settings will require a focus on poisoning, the 10-29 age group, and the elderly. This paper will be valuable for future policies aiming to reduce the societal burden of suicide and self-harm.

Objective : The aim of this study was to find associations between specific symptoms and suicidal behavior by using global severity on depression scales. Methods : Data were obtained from 1,183 patients of CRESCEND study. Factor analysis of the 17-item Hamilton Rating Scale for Depression (HAM-D) and the Beck Depression Inventory-II (BDI-II) was used to compare symptom clusters between the past suicide attempters and the non-suicide attempters, among the patients with depressive disorders. Results : Factor analyses of HAM-D and BDI-II extracted three factors. Suicide attempters had significantly higher scores on core factor of HAM-D, including depressed mood, feeling of guilt, suicide, work, and activities. The higher scores on all factors of BDI-II or scores correlated with a total of 7 suicide attempts and with known risk factors for suicidal behavior. Conclusion : These findings suggest that the suicide attempters complained of more cognitive, affective, somatic symptoms on BDI-II, but the core factor on HAM-D was the only differentiated factor between the two groups. Clinician-rated scales as well as self-reported questionnaires were valid in measuring suicidal attempts, and the clinical profile may help in guiding the studies of biological correlates and the treatments to reduce suicide risk.

Objectives Although impulsivity has long been thought as an important factor influencing suicidal behaviors, it is unknown whether impulsivity increases the risk of dying from suicidal behaviors and what specific component among constructs of impulsivity contributes to the risk of dying among suicide attempters. Methods To elucidate the association between impulsivity and medical lethality of suicide attempt among suicide attempters, we consecutively recruited 46 suicide attempters who visited an emergency room of a general hospital located in a metropolitan area, Seoul, Republic of Korea, due to suicide attempts and consented to participate in this study. Then we assessed medical lethality with the Beck Lethality Scale (LS) and impulsivity with the Korean version of the Barratt Impulsiveness Scale-11-Revised (BIS). Demographic variables were obtained from medical records and structured social work reports for suicide attempters. Results Although total scores of the BIS did not correlate with LS scores, only the scores of self-control, that is one of the Barrett's six theoretical constructs of impulsivity in which the higher score indicates less self-control and more impulsivity, had a significant positive correlation with scores of LS (p = 0.003). The association remained significant after adjusting for variables known to affect suicide lethality such as job status, recent alcohol consumption, diagnosis of depressive disorders, and having a plan for suicide (${\beta}=0.429$, p = 0.009). Conclusions Not impulsivity in general, but poor self-control, in particular, predicts lethal suicidal behaviors among suicide attempters. The degree of self-control should be evaluated when assessing patients with elevated suicide risk, and proper measures should be installed to prevent possible future lethal suicide attempts.
