In a study led by PISC Past Trainee Beidi Dong, PhD, Dong et al. address two questions to understand whether and how place-based interventions targeting micro-geographic places can help to reduce the co-occurrence of violence and poor health. The first question Dong et al. sought to answer was, "Does the co-occurrence persist after adjusting for shared selection factors at micro-geographic locations?". The second, "What are the mediating mechanisms between living at violent crime hot spots and deteriorated health?".
After adjusting for measured confounders, Dong et al. found that individuals in violent crime hot spots continued to have lower levels of self-rated general health, higher health limitations, and health problems. The study identified three modifiable mediating mechanisms, whereby interventions may further break the link between living with violence and deteriorated health. These three modifiable mechanisms include lower perceptions of safety, collective efficacy, and police legitimacy. These mechanisms provide insights into the complex relationship between violence and poor health while also providing avenues to strengthen collaboration between public health and law enforcement to address poor health in crime spots.
