Sexual violence was defined as forced sex, coerced sex and forced touching. Five percent of girls had experienced forced sex before age 18, and coerced intercourse was reported by 9% of girls, according to the report. In addition, almost 90% of girls who had experienced sexual violence said that it first occurred between ages 13 and 17. The authors recommended that efforts to address issues surrounding sexual violence should "focus on prevention of perpetration by men of sexual violence, and since sexual- and intimate-partner violence might have common roots, local and national initiatives could be reviewed, adapted and scaled up for this purpose." According to the researchers, three-quarters of the boys and men who perpetrated the sexual violence were related or known to the girls (IRIN/PlusNews, 5/13)."
