The Association Between Child Abuse and Attempted Suicide

Area of Science:

• Public Health
• Child Psychiatry
• Epidemiology

Background:

• Child abuse and suicidal behavior are prevalent issues among young populations.
• Adverse childhood experiences, including abuse, are linked to increased risk of suicidal behavior.
• Child abuse incidents have risen in Hong Kong, necessitating local investigation.

Purpose of the Study:

• To investigate the association between child abuse and attempted suicide in Hong Kong's child population.
• To utilize hospital electronic medical records for data analysis.

Main Methods:

• Retrospective analysis of electronic medical records from January 1, 1995, to July 31, 2016.
• Inclusion of patients under 18 diagnosed with child abuse or influenza (comparison group).
• Total sample size of 54,256 patients.

Main Results:

• Children with child abuse had significantly higher odds of hospital admission for attempted suicide compared to the influenza group.
• Adjusted hazard ratios for attempted suicide were 6.48 for sexual abuse and 4.83 for physical abuse.
• Female patients showed a higher risk of repeat suicide attempts; long-term follow-up revealed significant rates of attempts.

Conclusions:

• A significant association exists between child abuse and suicide attempts in Hong Kong children.
• Hospital admission records are valuable for identifying children at high risk for suicidal behavior.
• Findings suggest a need for enhanced, long-term intervention programs for child abuse survivors to mitigate suicide risk.
