Child maltreatmentis a global problem with serious life long consequences.There are no reliableglobal estimates for the prevalence of child maltreatment. Data for many

countries,especiallylow and middle income countries,are lacking.

studies reveal thatapproximately 20% of women and 5%一10% of men report being sexually abused as children.While 25%一50%of all children report being physically

abused.Additionally,many children are subject to emotional abuse(sometimes referred toas psychological abuse).

proportion of deathsdue to child maltreatment are incorrectly attributed to（归因于）falls, burns and drowning.
