The National Council for Childhood and Motherhood has observed 337 violations against children since the beginning 2014, Al-Ahram Arabic news website reported.
The council said the reports were recorded via a government helpline.
Sixty-seven of the cases involved child trafficking and 57 involved the killing of children.
