Teens are less likely to carry a gun if they live in a state requiring universal background checks in addition to federal requirements, according to a new study.

According to a news report, researchers from Indiana University wanted to check whether the federal law requirement that licensed gun dealers but not private sellers must perform background checks was enough to keep guns out of teens’ hands. They used data on high school students across the country from the Youth Risk Behavior Survey from 1993-2017, which includes several years before the National Instant Criminal Background Check System (NICS) launched in 1998. 

The report notes that the study showed just under six percent of teens carried a gun, and 83 percent of those were from states without a universal background check law. In addition, neither the NICS nor a state universal background check law alone was enough to significantly impact gun carrying rates but reduced the risk by 25 percent.

“Our study results suggest the NICS is only effective in reducing adolescent gun carrying when in the presence of state laws requiring universal background checks on all prospective gun buyers,” co-author Teresa M. Bell, Ph.D., said in a video abstract. “Further, states with universal background check laws need access to a national system such as the NICS in order to reduce teen gun carrying.”

Authors noted universal background checks might deter teens who otherwise may have tried to purchase a gun from a private seller and could stop some adults from buying guns they planned to sell to teens, says the report. 

“Implementing (universal background checks) nationally may decrease the number of guns accessible to adolescents and, in turn, reduce their gun carrying,” according to the study. The best way to protect kids from guns is to keep them out of the home, according to the AAP. In homes with guns, the AAP recommends keeping them locked and unloaded with ammunition locked separately.

“The sound application of rigorous scientific and public health methods has achieved marked success in other disciplines of injury prevention (eg, motor vehicle crash deaths, drowning), and parallel investments to advance the science of firearm injury prevention have the potential to reverse current trends in child and adolescent firearm deaths,” the authors wrote.
