Epidemiologic variations in childhood sexual abuse.

We retrospectively reviewed records of 566 children ranging from 6 months to 16 years of age who presented to a sexual assault crisis center. They represented 33.2% of all alleged sexual assault victims seen over a 36 month period. There were 103 males (18.2%) and 463 females (81.8%). Significant differences in presentation were demonstrated with respect to the victim's age, sex, and race, but the major factor influencing the variation is the victim/assailant relationship. Younger children were more likely than older children to present with histories of multiple assaults (p less than .0005), by known assailants (p less than .0005), occurring in the child's or assailant's home (p less than .001) and to report less violence (p less than .05). More risk of violence (p less than .0005) or evidence of trauma (p less than .0005) and less reporting of home assaults (p less than .0005) or multiple assault episodes (p less than .0005) were found in assaults by strangers when compared with non-stranger assaults. A lower frequency of reporting was found in females between 7 and 11 years of age. The dynamics of childhood sexual abuse are discussed in relationship to these findings. A number of victim and assailant related factors determine reporting patterns of childhood sexual abuse.
