This is a descriptive correlational study to determine factors affecting suicide attempts of the aged with suicide ideation by using data of a nation-wide survey, Korea National Health and Nutrition Examination Survey (KNHANES) conducted from January 2001 to December 2011. The survey was approved by Institutional Review Board of Korea Centers for Disease Control and Prevention. The subjects of this study were 2,347 elderly people with suicide ideation among 14,179 aged 65 or older. Statistically, multiple logistic regression analysis was conducted with independent variables showing a significant difference in suicidal ideation to obtain odds ratios, cutoff values, the efficiency of predicting suicide attempts. ModelⅠrevising psychological factors found to be highly related with suicide attempts in literature review, showed that the elderly experiencing a high level of stress and depression for over two weeks attempted suicide more than those with a low level of stress and without depression for over two weeks, respectively, in hierarchial regression analysis and its efficiency was 68.7%. ModelⅡ revising both of psychological and physical characteristics, revealed that the aged having a high level of stress, depression for over two weeks and depressive symptoms and having smoked attempted suicide more than those with a low level of stress and without depression for over two weeks, depressive symptoms and smoking history, respectively, in hierarchial regression analysis. As the positive and the negative predictive values and the efficiency of ModelⅡ recorded 72.8%, 77.5% and 77.2%, respectively, it is considered to be more appropriate to predict suicide attempts of elderly people.
