Childhood Sexual Abuse, Intellectual Disability, and Subsequent Physical and Mental Health Disorders: A Matched Cohort Study

This study assesses whether children with intellectual disability (ID) are more at risk of sexual abuse and whether they have similar consultation rates for physical and mental health disorders than children without ID. The matched-cohort design study uses administrative databases of children who had a sexual abuse report corroborated by a child protection agency and a matched group from the general population. Children with ID were 3.5 times more likely to have a corroborated sexual abuse report when compared to their peers without ID and a higher post-abuse number of medical consultations for physical and mental health disorders. Children with ID are more at risk of sexual abuse and physical and mental health disorders and may also be more vulnerable to the effects of abuse.
