Questionnaire about a history of physical and sexual abuse in childhood. Results.\p=m-\A history of child physical abuse was reported more often by males (31.2%) than females (21.1%), while sexual abuse during childhood was more commonly reported by females (12.8%) than males (4.3%). Severe physical abuse was reported by similar proportions of males (10.7%) and females (9.2%). A greater percentage of females reported a history of severe sexual abuse (11.1%) compared with males (3.9%). Age of the respondent was not significantly associated with childhood abuse within any category for males. However, for females, the reported prevalence in childhood of sexual abuse, co-occurrence of physical and sexual abuse, and both categories of severe abuse decreased with increasing age of the respondent. Conclusions.\p=m-\A history of childhood maltreatment among Ontario residents is common. Child abuse may be more prevalent in younger women compared with older women, or there may be a greater willingness among younger women to re- port abuse.
