Association between Childhood Trauma and Suicidal Behavior in the General Population

Area of Science:

• Mental Health
• Psychiatry
• Public Health

Background:

• Childhood trauma is a significant public health concern.
• Understanding the long-term impact of various childhood adversities on adult mental health is crucial.
• Suicidal behavior remains a major global health issue with complex etiological factors.

Purpose of the Study:

• To investigate the associations between different types of childhood trauma and suicidal behavior in the general South Korean population.
• To examine the relationship between childhood trauma and mental health indicators such as anxiety, depression, and perceived stress.
• To assess the impact of childhood trauma on health-related quality of life.

Main Methods:

• A cross-sectional mental health survey was conducted with 1,490 South Korean adults.
• Participants completed questionnaires on childhood trauma history (bullying, emotional, sexual, physical abuse) before age 12.
• Validated scales assessed suicidal behavior (ideation, planning, attempts), anxiety, depression, self-esteem, resilience, perceived stress, and quality of life.

Main Results:

• Any childhood trauma was linked to higher anxiety and depression (Hospital Anxiety and Depression Scale), higher perceived stress (Perceived Stress Scale), and lower quality of life (EuroQol 5D).
• Individuals with childhood trauma showed significantly higher rates of current suicidal ideation and histories of suicide planning and attempts.
• Multivariate analyses revealed bullying victimization and sexual abuse were significantly associated with all forms of suicidal behavior, while physical abuse correlated with suicide planning and attempts.

Conclusions:

• Childhood trauma is strongly associated with increased suicidality, anxiety, depression, and perceived stress, alongside diminished health-related quality of life in the general population.
• Specific types of trauma, namely bullying and sexual abuse, demonstrate robust associations with diverse suicidal behaviors, even after adjusting for confounding factors.
• These findings underscore the critical need for early intervention and support for children experiencing trauma to mitigate long-term mental health consequences and reduce suicide risk.
