Every year, there are an about 31,000 homicide(杀人) deaths in children under 15.This number underestimates the true extent of the problem, as a significant proportion of deaths due to child maltreatment are incorrectly attributed to falls, bums and drowning.
Child maltreatment causes suffering to children and families and can have long-term consequences. Maltreatment causes stress that is associated with disruption in early brain development. Extreme stress can impair the development of the nervous and immune systems. Consequently, as adults, maltreated children are at increased risk for behavioural, physical and mental health problems. Via the behavioural and mental health consequences, maltreatment can contribute to heart disease, cancer, suicide and sexually transmitted infections.
Beyond the health consequences of child maltreatment, there is an economic impact, including costs of hospitalization, mental health treatment, child welfare, and longer-term health costs.
A number of risk factors for child maltreatment have been identified. These risk factors are not present in all social and cultural contexts, but provide an overview when attempting to understand the causes of child maltreatment.
It is important to emphasize that children are the victims and are never to blame for maltreatment. A number of characteristics of an individual child may increase the likelihood of being maltreated, such as being either under four years old or an adolescent, being unwanted, or failing to fulfill the expectations of parents and having special needs, crying persistently or having abnormal physical features.
