Taking Aim at Gun Violence


Though the epidemic of firearm deaths in the U.S. has long been viewed through a criminal justice lens, two UCLA Fielding School professors who are studying the issue say it must be tackled through prevention strategies.

Gun violence isn't just a criminal justice issue, it’s a public health issue, says Dr. Michael Rodriguez, a professor of community health sciences at the UCLA Fielding School and family medicine at the David Geffen School of Medicine at UCLA.

Rodriguez has been studying gun violence for more than 25 years. He and Dr. Ninez Ponce, UCLA Fielding School professor of health policy and management and director of FSPH’s UCLA Center for Health Policy Research, recently received a grant to explore the issue in California, where about 3,000 people died by gunfire in 2019 — 54% of them by suicide.

“Gun violence kills people,” Rodriguez says. “It also injures many more people and maims people and provides them with disabilities for life. These are health impacts. By recognizing that guns are causing these health impacts, we recognize that it’s a health problem. Once we recognize it as a health problem, we can think about it the way we do other health problems.”

Rodriguez points to COVID-19 as an example of what a public health response looks like. Once the deadly nature of the virus was understood, doctors, scientists, and the community at large looked for ways to mitigate the threat. They mapped and studied the virus, developed effective vaccines, investigated potential treatments, and outlined personal and collective interventions to help stop the spread of the disease.

“It’s the same way with guns,” Rodriguez says. “We can look at what’s going on. We can look at what are the risk factors. We can look at what we can do to reduce the gun violence in sensible ways and then implement them.” Previous gun violence reduction efforts, such as outlawing specific weapons, resulted in a drop in deaths and injuries, he says.

The three-year grant, which Rodriguez and Ponce received in 2020 from the philanthropic National Collaborative on Gun Violence Research, will support research on gun ownership and attitudes among under-studied groups represented in the population-based California Health Interview Survey (CHIS), which annually surveys more than 20,000 residents across California.

Ponce, the principal investigator of CHIS, considers the gun-violence epidemic in the U.S. to be even more than a public health issue. She calls it a “human rights crisis.”

“It’s the leading cause of pre-mature death in the United States, killing 38,000 people and causing nearly 85,000 injuries each year,” she says. “That’s more than 100 deaths and more than 230 wounded every day.”

Preventing death, disability, and injury from firearms will require research and data on what interventions might be most effective. “One of the pillars of public health is prevention,” Ponce says. “These preventable deaths and injuries fuel researchers and advocates to produce actionable data to promote policies and programs that reduce violence, especially among at-risk communities.”

Until recently, federal funding for gun-violence research was limited by a 1996 congressional provision that prevented the U.S. Centers for Disease Control and Prevention from using public funds for studies that “advocate or promote gun control.” Congress clarified the law in 2018, and allocated $25 million the following year to study gun safety, splitting the funds between the CDC and the National Institutes of Health.

According to the CDC, more people were killed by firearms than by traffic accidents in the U.S. in 2019: nearly 40,000. Motor-vehicle safety, too, has benefited from public health research over the years, as studies led to seat belt mandates and other regulations that significantly reduced car-accident injuries and deaths.

Rodriguez and Ponce will focus their research on young adults, veterans, immigrants, and members of the LGBT community. “We suspect there may be more people who own guns in these categories than we thought, because of the fear many of them have and the persecution many of them have experienced,” Rodriguez says. “Unfortunately, while fear frequently drives people to get a gun, with the thought that having that gun will increase their safety, the reality is that a handgun in the home increases the risks for homicide and for suicide in that home."

Veterans are at high risk of suicide from self-inflicted gunshot wounds, Ponce notes, and are more likely than other U.S. residents to own a firearm. According to a 2019 report by the Department of Veterans Affairs, the suicide rate is 1.5 times higher for veterans than for non-veterans, and firearms were the method in 70% of male veteran suicide deaths. In addition, guns were the leading cause of death among children and teens in 2019, according to the Coalition to Stop Gun Violence.

The aim of the UCLA Fielding School professors’ research and other public health explorations of gun violence is to inform public policies, Rodriguez says, adding that public sentiment already favors increased gun-safety measures. Multiple polls show that a majority of Americans, including a majority of gun owners, support such policies as universal background checks and allowing a judge to remove guns from people at risk of hurting themselves or others.

Rodriguez says he hopes to see gun safety addressed with the same nonpartisan energy as the opioid epidemic. “Republicans and Democrats are coming together to find sound ways to provide information about opioids, to provide laws to protect the public,” he says. “Everybody in the public knows that opioids are dangerous — they’re dangerous and let’s do something about it. Same thing we should be doing with guns: Get together with those we elect and help create safer environments.”

Ponce notes that the United States has more guns and more gun deaths than other high-income countries. The loss isn’t only in lives, but in dollars, with gun violence costing the U.S. more than $280 billion annually in medical care, criminal-justice costs, employer costs, and work loss. “Building research and data on gun violence enables policymakers and advocates to make strides toward gun-violence prevention,” she says. “It’s even more critical now, with all of the tragic events happening around the nation and with racial tensions amidst the pandemic, which has been fraught with devastating losses.”

Despite near-daily mass shootings in the U.S., Rodriguez remains hopeful that thoughtful research on firearms and the damage they inflict can generate enough public and political support to change laws and ultimately protect people from unnecessary injury and death. “I’ve seen it work,” says Rodriguez, whose research as a postdoctoral fellow at Stanford University contributed to the movement to outlaw cheap, low-caliber guns known as Saturday night specials, resulting in a statewide ban in 1997.

He believes sound research can inspire a similar movement nationwide. “Just like with tobacco, with opioids — we’ve got to change this around, and we can do it,” he says. “We can do it because people want things to be different. And I think we, in the health professions, can help advise on what it is we need to do to help make our communities and our homes safer.”
