Subsequent Risks of Self-Harm, Suicide Attempts, and Suicide in Adolescents
Overview
This study analyzes the risks of subsequent self-harm, suicide attempts, and suicide in adolescents following their first hospital-treated self-harm episode.
Background
Self-harm is a significant public health concern among adolescents aged 10-24 years, as it is a major risk factor for suicide. This study provides insights into the timing and demographics of subsequent self-harm and suicide risks following initial treatment.

Key Findings
Within 1 year, 17.3% of adolescents experienced subsequent self-harm.
8.3% had a suicide attempt, and 0.3% died by suicide within the same period.
The highest risks for self-harm and suicide attempts occurred in the first month post-episode.
Males showed the highest risk for suicide, while females had a higher risk for suicide attempts.
Children aged 10-12 years exhibited the greatest risk for first-month self-harm.
Using violent or multiple methods during the initial self-harm event increased the risk of all outcomes.
Clinical Implications
The findings indicate the need for immediate and ongoing support for adolescents following a self-harm episode.
Conclusion
The study highlights the elevated risk of subsequent self-harm and suicide following an initial self-harm episode.
