Lee: Risk Factors for Suicidal Ideation across the Life Cycle among Korean Adults: Korean Psycho-social Anxiety Survey



To identify the risk factors for suicidal ideation across the life cycle among Korean adults using data from 2015 Korean Psycho-social Anxiety Survey.


The data were statistically analyzed using hierarchical logistic regression analysis.


The factors associated with suicidal ideation among the young adult group were education level (odds ratio [OR] 1.62, 95% confidence interval [CI] 1.05~2.49), self-esteem (OR 1.19, 95% CI 1.12~1.27), stress (OR 3.26, 95% CI 2.07~5.15), anger control problems (OR 3.58, 95% CI 2.34~5.50), and depression (OR 2.59, 95% CI 1.66~4.04) whereas among the middle-aged adults the factors were education level (OR 1.58, 95% CI 1.12~2.23), existence of a spouse (OR 2.55, 95% CI 1.72~3.78), self-esteem(OR 1.13, 95% CI 1.08~1.18), stress (OR 2.46, 95% CI 1.81~3.33), anger control problems (OR 1.70, 95% CI 1.22~2.36), and depression (OR 2.64, 95% CI 1.91~3.64). Among the older adult group the findings were the existence of a spouse (OR 2.16, 95% CI 1.37~3.39), self-esteem(OR 1.22, 95% CI 1.13~1.32), stress (OR 2.21, 95% CI 1.38~3.54), anxiety (OR 2.42, 95% CI 1.46~4.02), and depression (OR 2.48, 95% CI 1.30~4.72).


The findings suggest that there may be a need for different suicide intervention programs to decrease suicidal ideation across the life cycle.
