Dating violence against adolescent girls and associated substance use, unhealthy weight control, sexual risk behavior, pregnancy, and suicidality

Context Intimate partner violence against women is a major public health co ncern. Research among adults has shown that younger age is a consistent ris k factor for experiencing and perpetrating intimate partner violence. Howev er, no representative epidemiologic studies of lifetime prevalence of datin g violence among adolescents have been conducted. Objective To assess lifetime prevalence of physical and sexual violence fro m dating partners among adolescent girls and associations of these forms of violence with specific health risks. Design, Setting, and Participants Female 9th- through 12th-grade students w ho participated in the 1997 and 1999 Massachusetts Youth Risk Behavior Surv eys (n =1977 and 2186, respectively). Main Outcome Measures Lifetime prevalence rates of physical and sexual dati ng violence and whether such violence is independently associated with subs tance use, unhealthy weight control, sexual risk behavior, pregnancy, and s uicidality. Results Approximately 1 in 5 female students (20.2% in 1997 and 18.0% in 19 99) reported being physically and/or sexually abused by a dating partner. A fter controlling for the effects of potentially confounding demographics an d risk behaviors, data from both surveys indicate that physical and sexual dating violence against adolescent girls is associated with increased risk of substance use (eg, cocaine use for 1997, odds ratio [OR], 4.7; 95% confi dence interval [CI], 2.3-9.6; for 1999, OR, 3.4; 95% Cl, 1.7-6.7), unhealth y weight control behaviors (eg, use of laxatives and/or vomiting [for 1997, OR, 3.2; 95% Cl, 1.8-5.5; for 1999, OR, 3.7;95% CI, 2.2-6.5]), sexual risk behaviors (eg, first intercourse before age 15 years [for 1997, OR, 8.2; 9 5%. CI, 5.1-13.4; for 1999, OR, 2.4; 95% Cl, 1.4-4.2]), pregnancy (for 1997 , OR, 6.3; 95% Cl, 3.4-11.7; for 1999, OR, 3.9; 95% CI, 1.9-7.8), and suici dality (eg, attempted suicide [for 1997, OR, 7.6; 95% Cl, 4.7-12.3; for 199 9, OR, 8.6; 95% CI, 5.2-14.4]). Conclusion Dating violence is extremely prevalent among this population, an d adolescent girls who report a history of experiencing dating violence are more likely to exhibit other serious health risk behaviors.
