Childhood adversity predicted suicidal ideation in older age: Results from a National Survey in Korea

Abstract

Objectives: Suicide is a major mental health concern in South Korea, where a rapid increase in suicide rates among older adults is evident. This study aims to understand the association of childhood adversity with suicidal ideation in later life, and whether gender differences in the effects of childhood adversity exist.

Method: The sample consisted of older adults aged 60 years and more in six waves of the Korea Welfare Panel Study from 2012 to 2017 (N = 4,105). A mixed effect logistic regression with random intercept was used to test the effects of childhood adversity on the risk of 12-month suicidal ideation.

Results: After controlling for socioeconomic status, psychosocial resources, and health conditions, the mixed effect models using longitudinal data indicated that parental death predicted an increased risk of suicidal ideation and that a greater number of childhood adversities predicted a higher likelihood of suicidal ideation. No gender differences were found in the effects of childhood adversity on suicidal thoughts.

Conclusion: These findings support a life course perspective, highlighting the importance of assessing early life disadvantages to understand suicidal ideation among older adults. The findings suggest that interventions targeting older adults who experienced parental death in childhood or multiple adversities may be effective in preventing suicidal ideation.
