A new study finds that many American teens -- both boys and girls -- suffer some form of physical, emotional, or sexual violence in a relationship.

Researchers from the Centers for Disease Control and Prevention found that one in five female students and one  in 10 male students who date have experienced some form of teen dating violence during the past year.

The CDC's national Youth Risk Behavior Survey has provided estimates of teen dating violence (TDV) since 1999 but changes were made to the survey in 2013 to capture more serious forms of physical TDV, screen out students who did not date and assess sexual TDV. Over the years, nationwide prevalence estimates of TDV have remained at about 9 percent for both males and females in this annual CDC survey.

Teen dating violence can provide a point of potential intervention as specific types of TDV have been associated with increased alcohol and tobacco use, depressive symptoms and suicidality, eating disorders, and high-risk sexual behavior, according to the study background.

Among 9,900 students who reported dating, survey results indicate that female students who dated during the past 12 months had a prevalence of physical TDV only of 6.6 percent, 8 percent for sexual TDV only; 6.4 percent for both physical and sexual TDV, and 20.9 percent for any TDV.

Prevalence of TDV among dating males in the preceding 12 months was 4.1 percent for physical TDV only, 2.9 percent for sexual TDV only, 3.3 percent for both physical and sexual TDV, and 10.4 percent for any TDV. While the vast majority of students did not report experiencing TDV, the authors note that most students who experienced TDV experienced more than one incident.

The question on physical TDV asked how many times someone "physically hurt you on purpose" and the new question on sexual TDV asked "how many times did someone you were dating or going out with force you to do sexual things that you did not want to do?"

All health-risk behaviors, including alcohol use, suicide ideation and drug use were most prevalent among students who had experienced both physical and sexual TDV and least prevalent among students who experienced no TDV.

"These results present broader implications for TDV prevention efforts. Although female students have a higher prevalence than male students, male and female students are both impacted by TDV, and prevention efforts may be more effective if they include content for both sexes," the study concludes.

The findings are detailed online in the journal JAMA Pediatrics.
