RESUMO
Early-life exposure to neighborhood violence can negatively affect children's socioemotional development and long-term health outcomes. Community-level interventions that modify the built environment to facilitate social encounters can have a positive impact on health. An example of such interventions is the building of green spaces and playgrounds. This case study describes collaboration among residents, local organizations, and a university that aimed to increase the utilization of a vacant lot by converting it into a green space with a playground. Informal conversations at volunteer gatherings and neighborhood association meetings indicated a positive impact of this project in the community. We propose a model for future program implementation and research to improve health in disinvested and disordered communities. We conclude that more research is needed on community partnerships that modify the built environment to decrease community violence. Community-based participatory research may be successful in evaluating future projects with this goal.
