Growing up in a home with domestic abuse can not only ruin your childhood but can also have profound and lifelong effects on your mental and physical health for the rest of your life. Adverse Childhood Experiences (ACEs) are an increasing international concern. The first study was conducted in San Diego in 1998 and has since spread all over the world including the Welsh ACE study in 2015 (http://www.wales.nhs.uk/sitesplus/888/page/88517/). These studies have been used to demonstrate the links between adverse childhood experiences and a wide range of physical and mental health problems throughout adult life. Research has found that, compared to people who grew up with no domestic abuse, you are between two and six times more likely to have also experienced one of the other nine ACEs. It is the profound message that comes out of the ACEs report that makes BRAVE EIP research and development such an important project.
