Prevalence of childhood sexual abuse in a community sample of Australian women.

OBJECTIVE

To ascertain the prevalence of childhood sexual abuse (CSA) in a community sample of Australian women.

DESIGN

Retrospective study, done in 1994, of cross-sectional data on the prevalence of CSA, collected as part of a larger two-stage case-control study of the possible relationship between CSA and alcohol abuse. Data were appropriately weighted to adjust for the different selection probabilities of cases and controls.

PARTICIPANTS

710 Women randomly selected from Australian federal electoral rolls.

RESULTS

One hundred and forty-four women (20%) had experienced CSA. In 14 of these 144 women (10%), the abuse involved either vaginal or anal intercourse (i.e., 2% of the sample population experienced such abuse). The mean age at first episode of CSA was 10 years, and most (71%) of the women were aged under 12 years at the time. Perpetrators of the abuse were usually male (98%) and usually known to the child; 41% were relatives. The mean age of abusers was 34 years, with a median age difference of 24 years from that of the abused individual. Only 10% of CSA experiences were ever reported to the police, a doctor or a helping agency (e.g., community organisations, such as sexual assault services).

CONCLUSION

The high rates of CSA (estimated to be 20% of all women) and low rates of reporting (10%) indicate the need for general practitioners and other health professionals to be aware that a history of such abuse may be common in women in the general population.
