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.

AbstractAbstract PDF
PURPOSE
This study has a purpose to suggest research and intervention directions for health promoting behaviors (HPB) of the Korean middle-aged in the future.
METHODS
Forty four articles on HPB of the Korean middle-aged were reviewed and analyzed. The articles analyzed are theses written for a doctoral or master's degree and published between 1995 and 2007.
RESULTS
1. As for the major characteristics of the subject groups, most of them were between 40 and 60 years old (61.4%), were females (79.5%), and resided in cities (84.1%). 2. The dependent variables adopted were physiological, psychological and cognitive factors (self-efficacy, knowledge of health management, etc.), HPB and factors related to Health Promoting Lifestyle Profile (HPLP). 3. The average scores of HPLP were 1.57~3.08 on a 4-point scale. The highest score was observed in self-actualization, and the lowest score in exercise. 4. Self-efficacy, perceived health status and income had significant correlations with HPB. 5. In regression analysis, self-efficacy, self-esteem and perceived health status were the most powerful predictors.
CONCLUSION
It is necessary to develop intervention tools for more diverse HPB of the Korean middle-aged. The interventions are recommended to focus on increasing exercise and to use strategies for improving self-efficacy and self-esteem.
