Incest

Printable PDF

Definition:  Sexual contact between blood relatives.  Often included in this group is sexual contact between stepparents and stepchildren.  Incest is considered by many experts to be a particularly damaging form of sexual abuse because it is perpetrated by individuals whom the victim trusts and depends upon.  In addition, support can also be lacking and pressure to keep silent powerful as fear of the family breaking up can be overwhelming to other family members.

Cultural Note:  There are, however, different cultural expectations and rules about incest.  For instance, in some areas of the Arab world and southern India, it is estimated that as many as 50% of marriages occur between first cousins.  In addition, in southern India, it is still common to see a maternal uncle marry the first daughter.
