One in 12 teens self-harm, study finds

One in 12 teenagers self-harm, with girls more likely than boys to deliberately hurt themselves.

In the first study of its kind, Australian researchers followed about 2000 Victorian students from age 15 to see how many self-harmed during adolescence and into their 20s.

They found self-harm was most common among 15-year-olds, particularly girls and teenagers with symptoms of depression and anxiety.
