This study investigates suicidal ideation and its associated factors by sex in Korean adults, focusing on health behaviors and health status.


Cross-sectional data of 6,969 adults (25–64 years) who completed the Fourth Korean National Health and Nutrition Examination Survey were analyzed.


In both sexes, those who were married, had higher educational attainment or were non-smokers experienced low stress and had good self-rated health showed lower suicidal ideation. Significant factors were age for men and subjective body image and sleep time for women. In men, those aged 45–54 years showed the highest suicidal ideation rate. The effects of stress and depression on suicidal ideation were higher in men than in women.


The development of a suicide prevention program for Korean adults requires different approaches for each sex. For working men aged 45–54 years, it should focus on the management of work-related stress and depression. For women, it should be a community support program for those who are less educated, have no job or experience a great deal of stress and depression.
