Firearm legislation, gun violence, and mortality in children and young adults: A retrospective cohort study of 27,566 children in the USA

Firearm-related injuries types in hospitalized children are associated with age, race, and state level legislation. Accidents are most prevalent in young children, Whites, and states with lenient gun laws, while suicide attempts are more common in adolescents, Whites, and states with lenient gun laws. Suicide attempts are also associated with the greatest odds of in-hospital mortality. To address firearm violence, consideration should be given to legislation that promote safe gun storage behaviors and restrict firearm accessibility to children.
