Domestic violence is a public health issue and there has been growing recognition that there are harmful consequences for children and young people living in violent homes. Tackling domestic violence is a priority in UK government crime control policies, in health and in policies on child protection and children’s welfare. This article considers the paediatrician’s role in the context of UK policy expectations for safeguarding children and young people, early intervention and providing universal, targeted and responsive services to address children’s needs. Based upon a review of the research literature on domestic violence and the role of the paediatrician, this article briefly considers the impact of domestic violence upon children’s health and wellbeing. It also makes practical recommendations for paediatricians on: presenting symptoms and diagnosis; supporting children and the non-abusive parent; referral; and working with others to safeguard vulnerable children.
