Rates of self-injury are even higher in parts of the United States, according to government data. Boys are half as likely to harm themselves.
Up to 30 percent of teenage girls in some parts of the United States say they have intentionally injured themselves without aiming to commit suicide, researchers have found.
About one in four adolescent girls deliberately harmed herself in the previous year, often by cutting or burning, compared to about one in 10 boys.
The overall prevalence of self-harm was almost 18 percent.
“These numbers are very high for both genders — that surprised me,” said Martin A. Monto, a sociologist at the University of Portland and lead author of the new research.
Dr. Monto and his colleagues drew on data from a risk behavior survey administered by the Centers for Disease Control and Prevention in 2015. Their report, published online in the American Journal of Public Health, included almost 65,000 public high school students in 11 states.
