According to the CDC, nearly 29 million U.S. women and 16 million U.S. men have experienced severe physical violence by an intimate partner at some point in their lifetime. Most of those experiences occur before the age of twenty-five. The evidence is clear that domestic violence takes a physical and emotional toll on individuals, families and communities. Those exposed both directly and indirectly are at a greater risk of mental health disorders, infectious and chronic diseases and death. And the global annual cost in lost productivity, health care, and law enforcement is estimated to be in the trillions. This Forum event, held during National Domestic Violence Awareness Month, explored the many dimensions of domestic violence, the need for evidence-based prevention strategies and the role that the public and private sectors need to play to shift the conversation from intervention to preventive action. The panel included thought leaders and experts in public health and research coming together to advance the prevention of domestic violence. This event was Presented jointly with The Huffington Post on October 24, 2016. Watch the entire series from The Forum at Harvard T.H. Chan School of Public Health at www.ForumHSPH.org.
