Adapting and retesting evidence-based child maltreatment prevention programs: a case study in Canada.

This special issue of Health Promotion and Chronic Disease Prevention in Canada is timely, as child maltreatment is a significant public health problem; globally, the number affected is at least in the hundreds of millions. One-quarter of adults report having been physically abused and over one-third emotionally abused as children; one in 5 women and one in 13 men report having been sexually abused. Recent national surveys of violence against children conducted in Africa and in other low- and middle-income countries reveal rates of childhood physical, sexual and emotional abuse even higher than the global rates.
