This study was done to investigate the prevalence of suicidal ideation and associated factors in Korean adults.
From the database of the 5th Korean National Health and Nutritional Examination Survey conducted in 2010, cross-sectional data for 6,283 adults (> or =20 years) were used in this analysis.
One-year prevalence of suicidal ideation was 14.8%. Higher suicidal ideation was found for women, elders, adults who were divorced or separated, who were in the lower socio-economic class, were alcohol dependent, had a short sleep time, and had higher perceived stress and depression. On stepwise multivariate logistic regression analysis, depression (odds ratio 6.89 [95% confidence interval 5.18~9.16]), perceived stress(3.52 [2.66~4.65]), being woman (1.72 [1.32~2.26]), being an elder (> or =65 yrs) (1.78 [1.07~2.96]), low education(3.52 [2.66~4.62]) and not married (1.48 [1.04~2.12]) were associated with suicidal ideation in Korean adults.
The results indicate that suicidal ideation is highly prevalent in Korean adults, especially in people with depression or high perceived stress. Identification of high-risk group and suicide prevention programs are warranted to reduce the prevalence of suicidal ideation.
