Adolescent Self-Harm

摘要

Canadian child psychiatrists are seeing increasing numbers of adolescents with intentional self-harm. In Ontario, the rates of adolescents presenting at emergency departments rose 135% from 2009 to 2017 ( ). Large increases in adolescent self-harm have been reported in many other countries. With, to my knowledge, one striking exception: In a study of Danish health administrative records, Sarah Steeg and her co-authors found that the incidence rate of self-harm among adolescents aged 10–19 years peaked in 2007 (at 25.1/10,000 Danish youths), and then decreased steadily to 13.8/10,000 in 2016 ( ). What have the Danes done differently?
