The study’s results are particularly troublesome for older people who live in violent neighborhoods, who are more prone to loneliness and might already have chronic health issues like diabetes, obesity or heart disease, said Tung, whose research focuses on disparities in chronic disease management. Loneliness is a growing health concern, and a key predictor of mortality in the U.S. Seventy-seven percent of the study’s respondents were age 50 and up.
“The association between violence exposure and loneliness is a really interesting one, because there’s such a strong link,” Tung said. “The pervasiveness of violence seems to be more evident now than ever. What does that sense of violence in our culture do more broadly to loneliness?”
Social withdrawal might be a survival strategy in violent neighborhoods, but it’s not a good long-term option, added study co-author Monica E. Peek, an associate professor at the University of Chicago and the associate director of the Chicago Center of Diabetes Translation Research.
“Someone who is socially isolated and lonely has a higher risk for cardiovascular disease, just like someone who has a history of smoking. Loneliness is a public health issue with real health implications,” Peek said. “Violence impacts more than just the victims, but the whole community. Everyone’s health is potentially affected.”
The study’s findings tie into a bigger conversation happening nationwide about how issues like loneliness, food insecurity and housing impact a person’s physical and psychological health, Peek added.
“Our health care system is changing and evolving, and we’re starting to think not just about medical care but the social needs of our patients, and trying to use the medical system as a way to integrate those needs. Having a more holistic approach will better help our health outcomes,” she said.
In addition to Tung and Peek, the study’s authors included Louise C. Hawkley, senior research scientist with NORC at the University of Chicago; and Kathleen A. Cagney, professor in UChicago’s Department of Sociology.
The second report, led by medical student by Nichole A. Smith at the University of Chicago Pritzker School of Medicine, quantified a connection between exposure to community and police violence and hypervigilance.
Hypervigilance, a heightened emotional state of always feeling “on guard,” can prevent people from making healthy lifestyle choices. Chronic hypervigilance can lead to hypertension, cardiovascular disease, memory impairment, anxiety disorders and difficulty regulating emotions.
“It’s a very well-studied phenomenon, mostly in veterans. But it’s so poorly studied in community-based settings where you have this chronic exposure to violence,” Tung said.
The study found a surprisingly strong association between hypervigilance and exposure to police violence more than community violence. Exposure to community violence resulted in a 5.5% increase in the hypervigilance score, while exposure to police violence was associated with a 9.8% increase. Participants who experienced a traumatic event during a police stop were associated with a 20% increase in hypervigilance scores.
The findings suggest a complex association between police violence and the mental and physical health of community members. It raised the question of whether hypervigilance, both among residents and police officers, could possibly lead to harmful escalations during police stops.
The study said more trauma-informed policing and opportunities for community-building activities between police and community members, such as the CAPS police baseball league with community members, could help reduce hypervigilance on both sides and prevent situations from escalating into harmful ones.
Tung was inspired to do these two studies after she noticed more of her patients who live in violent neighborhoods were struggling to follow their prescribed health regimens.
“They would be hesitant to join walking groups because they were afraid to walk in their neighborhoods. Or I’d ask, ‘Why didn’t you get your medications on time?’ And they’d say, ‘Well, I could only get a ride at night, and I don’t want to leave the house at night.’ That kind of thing was coming up a lot more,” Tung said.
In addition to Smith and Tung, the study’s authors included Dexter R. Voisin, dean and professor of social work at the University of Toronto; and Joyce P. Yang, a postdoctoral fellow at Stanford University.
