Child sexual abuse (CSA), also called child molestation, is a form of child abuse in which an adult or older adolescent uses a child for sexual stimulation. Forms of child sexual abuse include engaging in sexual activities with a child (whether by asking or pressuring, or by other means), indecent exposure, child grooming, and child sexual exploitation, such as using a child to produce child pornography.
CSA is not confined to specific settings; it permeates various institutions and communities. CSA affects children in all socioeconomic levels, across all racial, ethnic, and cultural groups, and in both rural and urban areas. In places where child labor is common, CSA is not restricted to one individual setting; it passes through a multitude of institutions and communities. This includes but is not limited to schools, homes, and online spaces where adolescents are exposed to abuse and exploitation. Child marriage is one of the main forms of child sexual abuse; UNICEF has stated that child marriage "represents perhaps the most prevalent form of sexual abuse and exploitation of girls". The effects of child sexual abuse can include depression, post-traumatic stress disorder, anxiety, complex post-traumatic stress disorder, and physical injury to the child, among other problems. Sexual abuse by a family member is a form of incest and can result in more serious and long-term psychological trauma, especially in the case of parental incest.
