Roughly 7 percent of young Americans between the ages of 11 and 18 who died by homicide in recent years were killed by intimate partners, a new study finds.

Key results from the University of Washington School Of Medicine study, which was published in JAMA Pediatrics:

• 2188 people between 11 and 18 years old were killed in violent deaths from 2003 and 2016.
• In 150 of those deaths, an intimate partner was responsible for the crime — about 7 percent of the time.
• 135 of the victims were female and the average age of the victims was 16.8.
• 102 of the perpetrators in the crimes were at least 18, with their average age being 20.6.
• 94 of the perpetrators were the current intimate partners of the victims.

"Adolescents, particularly girls, in dating relationships may face risk of homicide, especially in circumstances of a breakup or jealousy and when perpetrators have access to firearms. Understanding homicide in early dating relationships can inform prevention and intervention efforts tailored to adolescents," the study results read.

Study author Avanti Adhia of the University of Washington told NPR that the results show that intimate partner violence does not just occur among adults.

"People think that intimate partner violence among adolescents is less serious than among adults," Adhia said. "It's important to highlight that this can really lead to death. It's not something to brush off as 'This is just an argument between kids.'"
