More than 100 governments today made historic commitments to end childhood violence, including nine pledging to ban corporal punishment - an issue that affects 3 out of every 5 children regularly in their homes. These commitments were made at a landmark event in Bogotá, Colombia, where government delegations are set to agree on a new global declaration aimed at protecting children from all kinds of violence, exploitation and abuse.

Also at the event, which is hosted by the Governments of Colombia and Sweden together with the World Health Organization (WHO), UNICEF and the United Nations Special Representative of the Secretary-General on Violence against Children, several countries committed to improve services for childhood violence survivors or tackle bullying, while others said they would invest in critical parenting support - one of the most effective interventions for reducing violence risks in the home.

"Despite being highly preventable, violence remains a horrific day to day reality for millions of children around the world - leaving scars that span generations," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. "Today countries made critical pledges that, once enacted, could finally turn the tide on childhood violence. From establishing lifechanging support for families to making schools safer places or tackling online abuse, these actions will be fundamental to protecting children from lasting harm and ill health."

Over half of all children globally - some 1 billion - are estimated to suffer some form of violence, such as child maltreatment (including corporal punishment, the most prevalent form of childhood violence), bullying, physical or emotional abuse, as well as sexual violence. Violence against children is often hidden, mostly occurs behind closed doors, and is vastly underreported. WHO estimates that fewer than half of affected children tell anyone they experienced violence and under 10% receive any help.

Such violence not only constitutes a grave violation of children's rights but also increases the risk of immediate and long-term health issues. For some children, violence results in death or serious injury. Every 13 minutes, a child or adolescent dies as a result of homicide - equating to around 40 000 preventable deaths each year. For others, experiencing violence has devastating and life-long consequences. These include anxiety and depression, risky behaviours like unsafe sex, smoking and substance abuse, and reduced academic achievement.

Evidence shows that violence against children is preventable, with the health sector having a critical role to play. Proven solutions include parenting support to help caregivers avoid violent discipline and build positive relationships with their children; school-based interventions to strengthen life and social skills for children and adolescents, and prevent bullying; child-friendly social and health services for children that experience violence; laws that prohibit violence against children and reduce underlying risk factors such as access to alcohol and guns, and efforts to ensure safer internet use for children. Research has shown that when countries effectively implement such strategies, they can reduce violence against children by as much as 20-50%.

In line with the UN Convention on the Rights of the Child, the first global targets for ending violence against children were established in the United Nations' Sustainable Development Goals. Progress in reducing overall prevalence of childhood violence has however been slow, despite gains in some individual countries. Around 9 in 10 children still live in countries where prevalent forms of childhood violence such as corporal punishment, or even sexual abuse and exploitation, are not yet prohibited by law.

Over 1000 people are attending this first-ever Ministerial Conference on Violence against Children, including high-level government delegations, children, young people, survivor and civil society allies.

Specific pledges at the event include among others, commitments to end physical punishment, to introduce new digital safety initiatives, increase the legally permitted age of marriage and to invest in parenting education and child protection. WHO provides significant support for efforts to end childhood violence, through technical guidance, guiding effective strategies for prevention and response, and conducting new research and data, including its global status reports.
