This policy brief explores the intersections between family violence, community violence, and health and recommends new violence prevention strategies that use a coordinated and comprehensive approach. It begins by discussing results of the Adverse Childhood Exposures (ACE) study that indicate as the extent of exposure to adverse events increases in a child's life, the number of negative health outcomes throughout the lifespan increases, including chronic lung disease, heart and liver disease, poor sexual and reproductive health outcomes, depression, alcohol and drug dependency, and suicide. Adverse health outcomes in adults who have been exposed to violence are also described. Following sections discuss the increased health care and societal costs of violence, strategies for preventing violence, and preventing violence to promote healthy outcomes. Policy recommendations are then made for developing a comprehensive, collaborative, systems-based approach to violence prevention. Recommendations include: targeting violence prevention resources toward evidence-informed, high impact programs and policies; supporting multi-sector collaborations and collaboration between school districts, public health, and community service agencies; and supporting comprehensive clinical violence prevention strategies through health care financing policies. 24 references.
