One in five children in Israel has been sexually abused, according to a large study out of the University of Haifa Faculty of Social Work , Israel Radio reported on Monday. The study surveyed 12,000 people between the ages of 11 to 17. Most of the victims said they did not report the abuse due to embarrassment, or that they didn't know where to turn or due to fear of punishment by the abuser for reporting. The study found that the percentage of boys who are sexually abused in Israel is slightly higher than girls. Professors Rachel Lev-Wiesel and Zvi Eisikovits, who led the study, surveyed youth from every sector in Israel except for the haredim who did not participate.
