Nearly 14% of teens who participated in a survey reported trying to kill themselves, with transgender teens reporting the highest rates of suicide attempts. Among female to male teens, the language the study uses for transgender male teens, more than half (50.8%) said they’d tried to take their lives, according to the study, published Tuesday in the journal Pediatrics.  “Gender identity is one’s own understanding of being male, female, neither, or both,” Russell B. Toomey, lead author of the study and an associate professor of family studies and human development at the University of Arizona, wrote in an email.
