Each year, 20,000 children and adolescents across the U.S. lose a parent to gun violence, while an estimated two to three times more have a parent who has been injured due to a firearm. To better understand the mental health impact of parental firearm injury, investigators from Mass General Brigham analyzed records from a large health insurance database, finding that in the year following a parent’s injury, children had increases in psychiatric diagnoses and mental health visits, especially if the parent had suffered a severe injury.
