Could Cutting Urban Blight Reduce Teen Murders? [news release]

From the 7 March 2016 Children’s Hospital of Philadelphia news release

Analyzing the immediate neighborhood surroundings of teenaged homicide victims, Philadelphia researchers found that neglected conditions — vacant lots, poor street lighting, fewer parks and less-traveled thoroughfares — were in much greater abundance compared to neighborhoods where adolescents were safer. Without attributing cause and effect, the new study adds to previous research suggesting that modifying specific outdoor features with low-cost improvements may foster community interaction and potentially reduce youth violence in cities.

“Homicide is a leading cause of death in U.S. adolescents and young adults, especially among African Americans, but the factors influencing violence are complex,” said corresponding author Alison J. Culyba, MD, MPH, an adolescent medicine specialist and epidemiologist at The Children’s Hospital of Philadelphia (CHOP). “Large-scale violence-prevention programs addressing poverty and educational disparities are absolutely necessary, but may require long-term investment to yield results. We focused on a different level — modifiable features of the built environment that might be factors in violence risk.”

Culyba and her CHOP co-authors collaborated with researchers from the Perelman School of Medicine at the University of Pennsylvania, led by epidemiologist Charles C. Branas, PhD, the senior author and director of the Penn Injury Science Center.

The study appeared today in JAMA Pediatrics.

“One theory that resonated with a lot of the things we found points to the importance of busy streets in promoting outdoor activity, interaction and cohesion in communities, which could potentially deter street violence,” said Branas, who has led several previous studies suggesting that urban parks and greening vacant lots encourage people to become invested in maintaining their neighborhoods and may reduce violent crime.

Both Culyba and Branas stress that this study does not show that street features and other elements cause or reduce homicide. Rather, they say, street lighting, pedestrian infrastructure, public transit, parks and vacant lot greening may be promising targets for future research to discover whether such interventions may provide social and health benefits.
