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.

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.

목 적: 세로토닌 활성도와 척도를 이용하여 세로토닌과 수면, 세로토닌과 자살 사고, 자살과 수면과의 상호 관련성을 평가하려고 하였다. 방 법: 주요우울증으로 진단된 65명을 대상으로 선택적 세로토닌 재흡수 억제제를 투여 받기 전 우울증의 심각도, 수면 양상, 자살 사고 정도를 평가하고 소리 자극과 뇌파를 이용하여 세로토닌 활성도 수치를 측정하였다. 결 과: Beck Depression Inventory (BDI) 중 불면 척도를 기준으로 두 군으로 나누어 비교한 결과 불면증이 있는 군은 없는 군에 비해 총 BDI 점수와 BDI 중 자살 항목 점수가 유의하게 높았다. 하지만 두 군 간의 세로토닌 활성도에서 유의한 차이는 없었다. 자살 시도 과거력이 있는 군과 자살 시도 과거력이 없는 군으로 나누어 비교한 결과 자살 시도군이 비시도군보다 BDI 중 자살 항목 점수가 유의하게 높았다. 또한 세로토닌 활성도는 통계적 유의성은 없었으나 자살 시도군에서 세로토닌 활성도가 더 낮은 경향성을 보였다. 결 론: 현재까지의 연구로는 자살, 수면, 세로토닌 모두가 서로 연관되어 있을 것이라는 가설은 아직까지 유효한 것 같다. 하지만 이러한 가설을 보다 명확하게 증명하기 위해서는 더 많은 연구가 필요할 것으로 보인다.

Objectives: This study investigated the association between oral health and suicide attempts in adults aged 65 years or older using the 7^th Korea National Health and Examination Survey (KHANES, 2016-2018). Methods: Of the total 24,269 participants of the 7^th KHANES (2016-2018), 1,488 adults aged 65 years or older who had an oral health examination were selected. Variations in suicide attempts with demographic characteristics and perceived oral health status were analyzed using the χ² test, and the association between oral health and suicide attempts was analyzed using the logistic regression model. Results: The suicide attempt rate was higher among older adults with chewing (p<0.01) and speaking (p<0.05) difficulties. The odds ratio for a suicide attempt was 1.05 times higher among those with tooth loss (p<0.05). Conclusions: Our results showed that older adults with tooth loss had an increased risk of suicide. Thus, it is important to prevent tooth loss, in the first place, through proper oral health management. If tooth loss occurs, appropriate treatment should be prioritized to facilitate functional recovery. Finally, national support is required for older adults with limited access to dental care.

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.

Purpose: The purpose of the study was to explore and describe the experience of Korean college students on suicide attempts. Methods: Eight students participated and data were collected through in-depth individual interviews between September, 2011 and April, 2012. Data were analyzed using Strauss and Corbin's grounded theory method. Results: Analysis showed that the central phenomenon of suicide attempt experience of college students was 'inextricable despair'. Causal conditions were 'sense of shame by failure to achieve perfect independence' and 'a big gap between reality and ideals'. Contextual conditions were 'extreme situation of being cornered' and 'excessive changes in emotions'. Intervening conditions were 'important others' and 'perspectives on the world'. Action/interaction strategies were 'temporary efforts' and 'gathering up one's mind'. Consequences were 'trauma as one's own hurt', 'conflict between life and death' and 'becoming mature'. Conclusion: The results of this study provide an in-depth understanding of the experience of college students with attempted suicide. It is necessary to develop programs to prevent suicide attempts by college students and these results can be used as a basis for program development.

연구목적 본 연구에서는 우울감을 주소로 내원한 청소년을 대상으로 비자살성 자해행동(Non-suicidal Self-Injury, 이하 NSSI) 의 빈도와, NSSI유무에 따른 사회인구학적, 임상적 특성을 비교하고, 이와 연관된 자살시도의 예측인자를 밝히고자 한다. 방 법 총 113명의 우울감을 주소로 내원한 12세에서 18세 청소년을 대상으로, 사회인구학적 특징, 자살행동과 NSSI, 심리상태에 대해 자기보고식 검사도구를 이용하여 평가하였고, 반구조화된 면담도구를 이용하여 정신과적 진단을 하였다. NSSI의 유무에 따라 두 군으로 나누어 이들의 사회인구학적 특징과 임상적 특징을 비교하였고, 로지스틱 회귀분석을 이용하여 유의한 변수 중 자살시도의 예측인자를 분석하였다. 결 과 분석에 포함된 113명의 청소년 중 42.1%에서 NSSI를 보고하였다. NSSI 가 있는 군은 없는 군에 비해 여성이 더 많았고, 우울, 불안 및 자살사고점수가 더 높았다. 자살 시도의 가장 연관성이 높은 예측인자는 NSSI, 가족이나 친구 중 자살/자해 경험, 총 상태불안점수였다[Odds Ratio (OR)=0.05, 95% Confidence Interval (CI)=0.01~0.20, p<0.001 ; OR=0.07, 95% CI=0.01~0.45, p=0.005; OR=1.10, 95% CI=1.02~1.19, p=0.013]. 결 론 본 연구를 통해 우울감을 주소로 병원에 방문한 청소년은 일반인구에 비해 NSSI의 빈도가 3배 정도 더 높고, NSSI가 동반된 경우 자살사고와 불안이 높며 자살시도와도 연관성이 매우 높음을 확인하였다. 본 연구 결과를 통해 병원에 방문한 우울한 청소년의 경우, NSSI에 대한 평가의 반드시 포함해야 하며 청소년 대상 자살예방프로그램 개발 시 NSSI에 대한 평가 및 접근을 반드시 포함해야 할 것으로 생각된다.

Objective : This study investigated the temperament and character traits associated with suicide attempts in patients with mood disorders. Methods : The temperament and character inventory (TCI) was administered to 150 patients who visited psychiatric clinics seeking treatment for mood symptoms. The patients were divided into three groups as follows : non-suicide ideation, suicide ideation and suicide attempt. We also gathered socio-economic data in order to rule out confounding variables. MANOVA was performed to analyze differences in personal temperament and character scores on the TCI between the three groups. Results : The self-directedness and cooperativeness subscales of the TCI are most influenced by the clinical symptoms rated by Beck Suicide Ideation Scale and Hamilton Depression Rating Scale. In the temperament scale, the suicide attempt group scored higher on the novelty seeking and harm avoidance items than the other two groups. The specific temperaments associated with suicidal behavior in patients with depression are impulsivity (NS2) and anticipatory anxiety or pessimism (HA1). Conclusion : In this study, we found that more risky patients who had previously attempted suicide had a temperament of impulsivity or pessimism. This finding suggests that a more cautious approach is needed to assess mood disorder patients with impulsive or pessimistic temperaments in order to prevent suicide attempts.

Purpose: The purpose of this study was to examine the meaning and essence of suicide for elderly people who had previously attempted suicide as an older person. Methods: Giorgi's descriptive phenomenology was used for analysis. The researchers carried out in-depth interviews, recordings and memos individually with four elders. The elders were individuals who had attempted suicide sometime in the past 5 yr. They were interviewed from 5 to 10 times using open-ended questions and a semi-structural format. Demographic data were also collected. Results: The meaning of suicide before a suicide attempt in older people had four core components: conflict with family, powerlessness and despair in their life with a drop in self-esteem, using internal and external resources to resolve their troubles and awareness of imminent crisis. Conclusion: These results of this study will increase understanding of suicide in older people by defining their subjective experience of suicide attempts and applying grounded data in the development of programs that provide concrete intervention strategies to prevent suicide in elderly people.
