OBJECTIVES This study aimed to identify the individual and regional characteristics that influence suicidal ideation among the Korean elderly population.
METHODS
Using data collected from the 2013 Korea Community Health Survey, a multilevel analysis was performed to establish an understanding of individual behavioral patterns and regional influences on suicidal ideation.
RESULTS
Among the 77,407 individuals sampled, 11,236 (14.5%) elderly people over 60 years of age experienced suicidal ideation. Among individual factors, age, frequency of communication with friends, religious activity, social activity, leisure activity, trust in neighbors, subjective stress level, depressive symptoms, and subjective health status were significantly associated with suicidal ideation. The results showed that the lower the regional deprivation level, the higher the suicidal ideation odds ratio. In terms of regional size, the most significant effects were found in rural areas.
CONCLUSIONS
This study suggested that suicidal ideation in the elderly is associated with community factors, such as the regional deprivation index, as well as personal factors.

OBJECTIVES Little information exists on the association between comorbidities of mental disorders and suicidal ideation in developing countries. The current study examined the relationship between the presence of comorbid mental disorders and suicidal ideation in the adult population.
METHODS
This cross-sectional study was conducted using the cluster random sampling method in 3 steps. Data were collected from a household assets survey and the self-administered 28-item General Health Questionnaire as first step in screening, and the Persian version of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition - Text Revision was used in the second stage to determine the prevalence of mental disorders. Bivariate and multivariate analysis were used to investigate the associations between mental disorders and suicidal ideation.
RESULTS
Of the 763 participants, 199 (26.1%) had 1 or more mental disorder. Forty-two (71.4%) subjects with comorbidities had a history of suicidal ideation, whereas 59 (7.7%) of all participants had a history of suicidal ideation. We found that major depressive disorder and obsessive-compulsive disorder were the most predictive of suicidal ideation in both sexes. The odds ratio for suicidal ideation associated with having 3 comorbid disorders was 2.70 (95% confidence interval [CI], 1.40 to 14.12) in males and 3.06 (95% CI, 1.25 to 15.22) in females.
CONCLUSIONS
Consistent with pervious data, our results confirmed that mental disorders and comorbidities of mental disorders were important predictors of suicidal ideation. Our findings are very useful for applied intervention programs to reduce the suicide rate in regions in which it is high.
