"Some previous research has found that aggression and sexual risk-taking are related, so it was not entirely surprising that bullies and bully-victims reported more sexual risk-taking than their peers," Melissa K. Holt said.
What's more, some research has found that kids and teens cope with being bullied by using drugs or alcohol, for instance. Acting out sexually may be another way young people respond to bullying, Holt told Reuters Health.
She led the research at the Boston University School of Education.
The study included almost 9,000 high school students from 24 schools who completed a survey about bullying and sexual behavior. "Risky sex" was defined as casual sex and sex while under the influence of alcohol or drugs.
About 80 percent of the students said they had not bullied other kids or been bullied themselves.
Seven percent of those teens reported ever having casual sex with someone they had just met or didn't know very well. And 12 percent said they had had sex under the influence.
The numbers were similar for students who said they had been bullied, but hadn't bullied others.
But among the six percent of kids who claimed to have acted as bullies, one quarter had engaged in casual sex and just over a third said they'd had sex while drunk or high.
Another six percent of students said they had both acted as bullies and been the victims of bulling. Of those teens, 20 percent had had casual sex and 23 percent reported having sex under the influence.
The researchers accounted for other childhood experiences that might lead to sexual risk-taking, but the link to bullying remained.
