Characteristics of victims and assaults of sexual violence--improving inquiries and prevention.

The purpose of our study was to provide descriptive data on victim and assault characteristics in sexual violence and to ascertain risk factors in the sequence of the assault events. Retrospective data were collected on all sexual assault victims presented to the sexual referral centre, the police and the Institute of Forensic Medicine in Aarhus, Denmark, during a five-year period. Four hundred and twenty-three victims were included. The annual incidence rate was 14.5 per 100,000 inhabitants aged 12-87 years and the "dark figure" was estimated to be 1.34. Median age was 21 years; 69% of the victims knew the assailant, and penile intercourse was reported in 59% of the cases. Young age and drinking alcohol were risk factors for the assault to take place in a public place. Information to high-risk groups identified by this study should be integrated in approaches of modifying sexual behaviour. Furthermore, the results from this study are useful in supporting staff and police investigators in the guidance of their efforts regarding treatment and inquiries.
