The health of socially excluded young people is suffering because professionals are failing to listen to their needs, according to research by the Children's Society.
The research is contained in a new report called Talking Sense, which accuses doctors, teachers and social workers of failing to listen to the young people most in need.
More than 100 young people in the North East and North West were interviewed, of whom 80 per cent had experienced physical and sexual abuse.
The majority say that despite seeking professional help, they are still suffering severe physical and mental health problems such as chronic stress, suicidal feelings, anger and violence to themselves and others.
The Children's Society has issued guidance for health professionals on how to improve healthcare services. Kathy Evans, policy manager at the charity, said: "This report shows that if professionals care and listen, it can make all the difference to children's lives."
