Males are younger perpetrators, with first perpetration occurring most often at 16 years old
TUESDAY, Oct. 8 (HealthDay News) -- Sexual violence perpetration appears to emerge earlier for males than females, with a link seen between perpetration and the viewing of violent sexual media, according to a study published online Oct. 7 in JAMA Pediatrics.
Michele L. Ybarra, Ph.D., M.P.H., from the Center for Innovative Public Health Research in San Clemente, Calif., and colleagues collected online data as part of the national Growing Up With Media study (2010 [wave 4] and 2011 [wave 5]). Recruitment was balanced on youths' biological sex and age (1,058 participants, aged 14 to 21 years).
The researchers found that nearly one in 10 youths (9 percent) reported some type of sexual violence perpetration in their lifetime, with 4 percent (10 females and 39 males) reporting attempted or completed rape. The mode age of first sexual perpetration was 16 years old (40 percent). Perpetrators reported greater exposure to violent X-rated media content. Younger beginning perpetrators were more often men (98 percent at 15 years or younger and 90 percent at ages 16 or 17). For ages 18 or 19 years, both sexes were relatively equally represented as perpetrators (males, 52 percent; females, 48 percent). Females were more likely to perpetrate against older victims, while males were more likely to perpetrate against younger victims.
"Findings suggest important differences between males and females in the etiology of adolescent sexual violence," the authors write.
