More kids are attempting suicide or thinking about it, according to a new study out Wednesday.
The rate of children's hospitalizations for suicidal thoughts or activity doubled from about 2008 to 2015, researcher Dr. Gregory Plemmons of Vanderbilt University told NBC News.
The study, published in the journal Pediatrics, looked at data from 49 children's hospitals. It found that girls made up nearly two-thirds of cases.

What's behind the uptick isn't clear to the researchers — "I don't have any one magic answer that explains why we're seeing this," Plemmons said.
