The Child and youth health service of the Canton of Geneva is an important actor in support of abused children attending school. Incidence of child abuse is stable at around 3.5 per 1,000 school children. Physical, psychological abuse and neglect are the types most frequently encountered. The main risk factors for abuse are precarious socio-economic situations, parenting issues and finally issues related to young people themselves. Although the incidence of abuse is stable in recent years, with respect to the growing number of children attending school, we can conclude that the absolute number of children at risk increases, confirming the need to develop and maintain common policies and prevention actions in this area.
