Researchers call for supports, coping strategies as youth self-harm rises
TORONTO — A new Canadian study showing a steady increase in youth self-harm highlights the need for more mental health support and proactive teaching of coping strategies to deal with emotional anguish, researchers say.
The study, published Monday in the medical journal JAMA Pediatrics, examined research papers from 12 Organization for Economic Co-operation and Development (OECD) countries, including Canada, that presented data for people aged 24 and younger between January 2000 and December 2024.
It found an average 3.5 per cent increase every year in self-injuries over that time period documented in hospital and doctor’s visits, with higher rates among girls than boys.
“There is a long and sustained trend in self-injury. So it’s not just a short-term blip, and it’s not just localized to a single jurisdiction, but it is happening everywhere, and it is happening at a large rate and scale,” said lead author Dr. Natasha Saunders, a pediatrician at the Hospital for Sick Children in Toronto.
