Objective: The aim of this study was to investigate the prevalence of depression and suicidal ideation among older Korean adults and the predictors of suicidal ideation.
Methods: We analyzed data from 5,604 Koreans aged 65 or older collected by the Korea National Health and Nutrition Examination Survey in 2012?2016, an annual national, cross-sectional, epidemiologic study of the Korean population. A chi-square test was used to assess differences in socio-demographic characteristics by suicidal ideation. Psychological variables, self-rated physical health, and the five dimensions of the Korean version of the EQ-5D (EuroQoL) were compared between four subgroups categorized according to the presence/absence of suicidal ideation and depression. Multiple logistic regression was used to estimate the predictive power of health-related quality of life variables, as well as physical and psychological factors regarding suicidal ideation.
Results: Overall, 11.5% of the sample reported suicidal ideation, and 20.0% of the suicidal ideation group were diagnosed with depression. Respondents with suicidal ideation had significantly lower levels of health-related quality of life than those without suicidal ideation. EQ-5D self-control (OR=1.42), anxiety/depression (OR=2.32), depression (OR=2.07), and self-rated physical health (OR=1.36) were found to significantly predict suicidal ideation.
Conclusion: Suicidal ideation without depression was prevalent among older Koreans. Self-control, anxiety/depression of EQ-5D, selfrated physical health, and depression predicted suicidal ideation. Interventions to screen older Koreans for early detection of suicide risk and prevention strategies should consider evaluating each EQ-5D dimension.
