Abstract

PURPOSE: Rates of hospital-treated self-harm are highest among young people. The current study examined trends in rates of self-harm among young people in Ireland over a 10-year period, as well as trends in self-harm methods.

METHODS: Data from the National Self-Harm Registry Ireland on presentations to hospital emergency departments (EDs) following self-harm by those aged 10-24 years during the period 2007-2016 were included. We calculated annual self-harm rates per 100,000 by age, gender and method of self-harm. Poisson regression models were used to examine trends in rates of self-harm.

RESULTS: The average person-based rate of self-harm among 10-24-year-olds was 318 per 100,000. Peak rates were observed among 15-19-year-old females (564 per 100,000) and 20-24-year-old males (448 per 100,000). Between 2007 and 2016, rates of self-harm increased by 22%, with increases most pronounced for females and those aged 10-14 years. There were marked increases in specific methods of self-harm, including those associated with high lethality.

CONCLUSIONS: The findings indicate that the age of onset of self-harm is decreasing. Increasing rates of self-harm, along with increases in highly lethal methods, indicate that targeted interventions in key transition stages for young people are warranted.
