Purpose: Suicide among adolescents is a serious problem worldwide, and especially, the suicide rate of teenagers is increasing rapidly in South Korea. This study was conducted to investigate the factors affecting the respective suicidal behavior in terms of home-environment characteristics, health behavior characteristics, and psychological health characteristics in Korean adolescents. Methods: The data of the Web-based Survey of the Youth Risk Behavior from 2015 to 2017 collected by the Korea Centers for Disease Control and Prevention (KCDC) was analyzed using multivariable logistic regression analysis. Results: The influential factors by depression and suicidal behavior (suicidal ideation (SI), suicidal plan (SP), and suicidal attempt (SA)) were female(adjusted odds ratios [aOR], 1.45, 1.69, 1.30, 2.19), age (aOR 1.03, 0.98, 0.97, 0.90), no family members (aOR 1.21, 1.36, 2.11, 2.32), living with only the father (aOR 1.05, 1.06, 1.07, 1.11), high economic status (aOR 1.15, 1.22, 1.34, 1.46), residence in relatives' home (aOR 1.6, 1.36, 2.34, 1.97), drinking experience (aOR 1.35, 1.47, 1.57, 1.76), smoking experience (aOR 1.28, 1.30, 1.31, 1.94), hospital treatment experience due to violence (aOR 2.18, 3.33, 6.24, 8.40), bad health status (aOR 1.23, 1.48, 2.00, 2.15), unhappiness (aOR 2.49, 6.14, 6.72, 8.89), and a lot of stress (aOR 6.05, 10.40, 4.86, 5.52). Conclusion: The suicidal behavior risk screening and prevention program for adolescents should be developed considering the subjective happiness and hospital treatment experience status due to violence that affects suicidal behavior.

Purpose: The purpose of this study was to investigate the relationship between patients with a neuropsychiatric history and features of their suicide attempt, in order to analyze the risk associated with psychiatrist prescribed drugs Methods: We retrospectively investigated cases of intentional overdose drug ingestion in patients greater than 14 years of age who visited OO emergency medical center between January 1, 2008 and July 31, 2010. We evaluated patient medical records to ascertain their age, sex, neuropsychiatric history, and components of ingested intoxicant. Information regarding any suicide reattempt was obtained after discharge through follow up telephone survey. SPSS version 13.0 was used for statistical analysis. Fisher's exact test was performed with p<0.05 considered statistically significant. Results: Ninety-six of 209 patients (46%) had a past history of psychological problems. Among those 96 patients with a history of psychological problems, 46(48%) used an overdose of the medicine prescribed by their psychologist in order to attempt suicide. However, for patients without a history of psychological problems, intoxication by neuropsychiatric drugs was insignificant. Neuropsychiatric patients required greater follow up care after discharge and exhibited significantly more suicide reattempts. Conclusion: This study revealed that patients sometimes use the medicine prescribed by their psychologist to attempt suicide. Therefore, an exhaustive plan to control the medicines prescribed to psychiatric patients should be established.

Objectives : The purpose of this study was to examine personality traits associated with suicidal symptoms (with history of suicide attempt or suicidal idea) in depressed patients. Methods : A sample 186 patients diagnosed with major depressive disorder was divided into two groups : suicidal group (with history of suicide attempt or suicidal idea, n=70) and non-suicidal group (without history of suicide attempt or suicidal idea, n=116). NEO Personality Assessment System were used to evaluate personality trait. Results : Neuroticism was high in suicidal group (p=0.041). In multivariate logistic regression, Neuroticism was also a significant influence on suicidal symptoms (Odds Ratio=1.04, 95% Confidence Interval 1.01-1.07, p=0.0145). Conclusions : High Neuroticism is a useful information to identify individuals at high risk of suicide in depressive patients.

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.

The purpose of this study is to investigate the relevance of discrimination and violence experienced by persons with disabilities to suicidal ideation of persons with disabilities. The study data used the 2014 national survey of the disabled persons and 6,332 people were included in the analysis. Suicidal ideation was defined as whether or not suicide was actually attempted in the last year. The reference group was a group without suicidal ideation and logistic regression analysis of violence discrimination and experience was performed. The study found that 18.5%(n=1.171) of people with disabilities had suicidal ideation. The risk of suicidal ideation was higher when there was language violence and mental violence because of being disabled. When adolescents experienced sexual harassment, sexual abuse, and sexual violence, the risk of suicide was 16.7(CI=4.22-66.18) times higher. The risk of suicidal ideation was 5.8(CI=2.34-14.6) times higher for those who did not know the violent offenders and 4.08(CI=2.05-8.12) times higher for coping strategies that ignored or tolerated violence. The risk of suicidal ideation was 1.60(CI=1.24-2.08) times higher in the case of discrimination experienced at the time of marriage and it was 2.73(CI=4.22-66.18) times higher when they had always felt the discrimination due to disability. The suicidal ideation that comes from experiences of violent experience and discrimination can appear as actual suicide. Therefore, it is necessary to support the suicide prevention program at the community level, along with the care and consideration of the family and society of the disabled for the well-being of the disabled.

Objectives: This study investigates the prevalence of suicide ideation and its the related factors by gender among Korean adults. Methods: National cross-sectional data from the database of the first and second year of $5^{th}$ Korean National Health and Nutritional Examination Survey (KNHANES V-1, V-2) were used for this study. 13,165 adults (${\geq}20$ years) were included in this analysis. Results: The prevalence of suicide ideation was 9.8% for men, 18.9% for women. Renal failure, depression, melancholy, stress, perceived health status, and smoking were significant risk factors among both men and women for suicide ideation. Divorced, separated or widowed of marital status and severe physical activity were related factors of suicide ideation for men. Low educational attainment, and alcohol dependency were associated factors of suicide ideation for women. Conclusions: There was gender difference of prevalence and risk factors of suicide ideation. These gender differences should be considered for planning and implementing suicide prevention program.

This study examined dietary habits and mental health according to generalized anxiety disorders (GAD) and caffeine consumption in adolescents. The data were collected from the 18^th Korea Youth Risk Behavior Survey with a sample of 51,850 students. The proportion of students in the GAD High-Risk·Caffeine consumption group (GHRCC) who consumed sweet drinks (p< .001), fast food (p< .001), and midnight meals (p< .001) every day was 15.6, 21.9, and 22.4%, respectively. These proportions were higher than those of students who consumed sweet drinks, fast food, and midnight meals 1-2 times a week, 3-4 times a week, or not at all. In addition, the proportions of GHRCC among students who responded "yes" to experiencing sadness and despair (p< .001), suicidal thoughts (p< .001), suicide plans (p< .001), suicide attempts (p< .001), and loneliness (p< .001) were higher than students who responded "no." The GAD High-Risk group (GHR) had higher odds with the consumption of midnight meals (OR: 2.51, 95% CI: 2.10-2.99), caffeine consumption (OR: 2.46, 95% CI: 2.21-2.74), and fast food (OR: 2.11, 95% CI: 1.75-2.55) than GAD Low-Risk group. Based on the above results, the risk of GHR was higher among students who consumed midnight meals, caffeine, and fast food daily than those who did not.

The rates and numbers of elderly suicide in Korea have been increased during 1985-1998. This indicates the seriousness of the problems which the elderly are faced with. So many late-life problems may push older people across the edges. Those in unbearable situations may call out fur helps, they may try to cope with various ways, or they may commit suicides. Because it is widely believed that suicide among the elderly can be understood as a personal solution or alternative to late-life problems in old age, the elderly\`s suicides seem to be an appropriate indicator in estimating seriousness of late-life problems. A comparison of the history of suicide research with other populations shows that the several late-life problems have been found with placing an individual elder at risks for increasing suicidal behaviors Research has identified such problems as financial insecurity, retirement, loss of social roles, physical illness, lack of social supports, and loneliness as the problems that increase the incidence of suicidal behavior. Though it is difficult far us to explain and understand the phenomenon of the elderly\`s suicide because of its complexity, we need to ascertain problems and social conditions behind suicides and also to prepare for some appropriate policy-tasks in light of social welfare for the aged, through examining the phenomenon. For explaining the elderly\`s suicide, the theoretical orientations are based on sociological perspectives in the paper. From the standpoints of social integration theory and exchange theory, this study is to examine the relationship between late-life problems and suicide. These two may have been fruitfully employed in conjunction with each other. Finally, this study would identify urgent late-life problems related with the elderly\`s suicide and suggest the relevant policies for Korean elders. Sometime in the near future, the government should be required to provide social welfare programs for the elderly, particularly for those at risk for increasing suicidal behaviors.

Background & Objectives: There were increasing evidence about the relationship between allergy related disease such as asthma, atopic dermatitis and allergic rhinitis and suicide ideation. However little was known about the concrete relatedness between severity and comorbidity of allergy related disease with suicide ideation. The objective of this study was to investigate the cases of the prevalence of suicide ideation among adolescents with allergy related disease such as asthma, atopic dermatitis and allergic rhinitis, and examine the association between allergy related disease and suicidal ideation among adolescents in South Korea. Methods: Data was based on Korean Youth Risk Behavior Web-based Survey(2014) which was a cross-sectional study containing 34,874 Korean middle and high school students who diagnosed with allergy related disease. We used the weights, strata and primary sampling unit information provided by the public use dataset to compute descriptive statistics and logistic regressions. Computations were done with SPSS version 20.0. Results: 19.9%, 15.6%, 13.8% of adolescents who suffered from one, two and three of allergy related diseases respectively reported having been thought of suicide ideation. Socio-demographic factors were adjusted as control variables. Students with greater severity of disease were more likely to have suicide ideation. Odds ratio for students who were absent one to three days from school because of allergies was 1.96(95% CI 1.51-2.46), and odds ratio for those who were absent more than four days from school was 3.60(95% CI 2.46-5.28). Conclusions: Given that adolescents' severity and comorbidity of allergy related disease were clearly associated with suicide ideation, suicide prevention programs for adolescents with allergy related disease should be improved by strategic approaches towards the severity and comorbidity of disease.

Objectives : The purpose of this study was to examine the prevalence and clinical characteristics of nonsuicidal self-injury (NSSI), and its association with suicide attempts among clinically depressed adolescents in Korea. Methods : In total, 113 depressed adolescents aged 12-18 years in South Korea were enrolled in this study. We assessed sociodemographic and clinical characteristics including suicidality and non-suicidal self-injury (NSSI) using various self-reported scales and semi-structured interview for diagnosis of psychiatric disorders. Demographic and clinical characteristics of the subjects were compared between NSSI and non-NSSI groups. We examined significant predictors of suicide attempts using logistic regression analysis. Results : Among 113 depressed participants, 48 (42.1%) adolescents were classified into the NSSI group. In the NSSI group, there were significantly more females, showed higher depression, higher state-anxiety, and more suicide ideation. The most predictive factors of suicide attempts were history of NSSI, observed suicide/NSSI behaviors of their family or friends, and total state anxiety score. Conclusions : NSSI is more common problem among clinically depressed adolescents and history of NSSI is a significant predictor of present suicide attempts. To include the assessment of NSSI for clinically depressed adolescent may be crucial for intervention programs for high risk adolescents of suicide in Korea.
