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 purpose of this study is to describe the prevalence of suicidal ideation and to investigate related factors contributing to suicidal ideation in elderly people with focus on comparison of gender differences. Methods: From the database of the Fourth Korean National Health and Nutrition Examination Survey (KNHANES-IV), the researchers selected 3,164 old adults aged over 65. The original study was a population-based epidemiological survey of health and nutrition in a stratified multistage clustered probability design. Data were analyzed by using ${\chi}^2$-test and t-test and multiple logistic regression with the SPSS/WIN18.0 program. Results: Suicidal ideation in women (37.5%) occurred more frequently than men (17.5%). Depression, stress, restriction on activities and quality of life were significant variables of suicidal ideation in both the men and women aged 65 over. Low educational levels and economic states were significantly associated with suicidal ideation in men but not in women. Conclusion: The development of a suicide prevention program for elders requires different approaches to the genders respectively. It is also recommended that programs be developed that can help control the variables identified in this study along with a follow-up study for verifying the model.

Purpose The purpose of this study is to develop a prediction model and decision rules for the elderly's suicidal ideation based on the Korean Welfare Panel survey data. By utilizing this data, we obtained many decision rules to predict the elderly's suicide ideation. Design/methodology/approach This study used classification analysis to derive decision rules to predict on the basis of decision tree technique. Weka 3.8 is used as the data mining tool in this study. The decision tree algorithm uses J48, also known as C4.5. In addition, 66.6% of the total data was divided into learning data and verification data. We considered all possible variables based on previous studies in predicting suicidal ideation of the elderly. Finally, 99 variables including the target variable were used. Classification analysis was performed by introducing sampling technique through backward elimination and data balancing. Findings As a result, there were significant differences between the data sets. The selected data sets have different, various decision tree and several rules. Based on the decision tree method, we derived the rules for suicide prevention. The decision tree derives not only the rules for the suicidal ideation of the depressed group, but also the rules for the suicidal ideation of the non-depressed group. In addition, in developing the predictive model, the problem of over-fitting due to the data imbalance phenomenon was directly identified through the application of data balancing. We could conclude that it is necessary to balance the data on the target variables in order to perform the correct classification analysis without over-fitting. In addition, although data balancing is applied, it is shown that performance is not inferior in prediction rate when compared with a biased prediction model.

Objectives : The purpose of this study was to examine psychosocial factors influencing suicidal ideation of community dwelling elderly, using the senior community center in Jeonnam Province. Methods : A total of 2,202 subjects (369 males, 1,833 females) were recruited. We evaluated sociodemographic factors, using a self-reporting questionnaire. Subjects completed the Geriatric Depression Scale-Short Form Korean Version (SGDS), Multi-dimensional Scale of Perceived Social Support (MSPSS), Korean version of the General Health Questionale-12 (GHQ-12) and Satisfaction with Life scale (SWLS), to assess psychosocial factors affecting suicidal ideation. Results : Among 2,202 subjects, 179 (8.1%) reported recent suicidal ideation. Self-perceptive health status (p<0.001) and physical disease (p=0.002) revealed differences between two groups. The scores of four scales in the suicidal group were significantly different from the control group: SGDS (p<0.001) and GHQ-12 (p<0.001) were higher, while MSPSS (p<0.001) and SWLS (p<0.001) were lower, in the suicidal ideation group than the control group. Multivariate logistic regression analysis revealed that physical disease (OR 2.575, 95%CI 1.022-6.492), SGDS (OR 1.181, 95%CI 1.120-1.246) and GHQ-12 (OR 1.192, 95%CI 1.108-1.283), were significantly associated with suicidal ideation. Conclusion : Findings support that physical disease, depression, and general mental health may correlate to suicidal ideation in the elderly.

Purpose: The aim of this study is to explore levels of suicidal ideation and identify subgroups of high suicidal risk among the depressed elderly in Korea. Methods: A descriptive cross-sectional design was adopted on secondary data from the 6th (1st year) Korean national health and nutrition examination survey (KNHANES). A total of 239 depressed elders aged 60 or over who participated in the KNHANES. The prevalence of suicidal ideation and its related factors, including sociodemographic, physical, psychological characteristics and quality of life (EQ-5D index) were examined. Descriptive statistics and a decision tree analysis were performed using the SPSS/WIN 23.0 and SPSS Modeler 14.2 programs. Results: Of the depressed elderly, 28.9% had suicidal ideation. Three groups with high suicidal ideation were identified. Predictive factors included perceived stress level, household income level, quality of life and restriction of activity. In the highest risk group were those depressed elderly with moderate and low levels of stress, less than .71 of EQ-5D index and restriction of activity, and 80.0% of these participants had suicidal ideation. The accuracy of the model was 80.8%, its sensitivity 85.9%, and its specificity 68.1%. Conclusion: Multi-dimensional intervention should be designed to decrease suicide among the depressed elderly, particularly focusing on subgroups with high risk factors. This research is expected to contribute itself to the policy design and solution building in the future as it suggests policy implications in preventing the suicide of the depressed elderly.

Objectives: This study aimed to investigate factors influencing suicidal ideation among Korean adults. Methods: Cross-sectional data from the fifth Korea National Health and Nutritional Examination Survey conducted in 2012 were analyzed in this study. The subjects were categorized into three groups by subjects' age(defined as young adults(20-39), middle-aged adults(40-59), and the elderly(60 or more). Data were analyzed by frequency, Chi-square test and multiple logistic regression using SPSS 18.0. Results: The factors influencing suicidal ideation were different among three age groups. The influencing factors were (1) gender, marital status, household income, perceived stress and depression in the young adult group, (2) household income, perceived health status, perceived stress and depression in the middle-aged group, (3) gender, regular physical activity, smoking, perceived health status, perceived stress and depression in the elderly group. Conclusions: The health education considering the characteristics of each age group should be developed and applied to prevent adults' suicidal ideation because the factors influencing suicidal ideation were revealed differently between the age groups.
