Physical and sexual violence are known public health hazards,1 imposing substantial physical and emotional burdens on those who have experienced such violence.2 Gay, lesbian, bisexual, and questioning adolescents are believed to be at higher risk than their heterosexual peers for violence.3 However, no nationally representative study has examined the holistic risk of violence to sexual minority adolescents, and some forms of violence (eg, sexual assault by a stranger), to our knowledge, have not been assessed.4 We used data from the National Youth Risk Behavior Survey (YRBS), conducted every 2 years by the Centers for Disease Control and Prevention, to quantify the risk of physical and sexual violence faced by sexual minority adolescents attending high schools in the United States.


For this cross-sectional study, we used pooled data from the 2015 and 2017 YRBS public use files to broaden the sample size and scope of our analysis. The survey in each of these years had a response rate of 60%.

The YRBS uses a 3-stage cluster sample of US counties within all states, schools within counties, and classrooms within schools to achieve a nationally representative sample of American adolescents. Students anonymously record responses on computer-scannable paper surveys administered during the school day. This study, which uses secondary, deidentified data, was exempted from institutional review board approval and informed consent as necessary for protection of public health under the common rule, at 45-CFR-46.102.

Participants in the YRBS in each year were asked to indicate their sex (female or male) and sexual orientation (heterosexual, gay or lesbian, bisexual, or not sure) and whether they had experienced any of 3 types of physical violence (past-year physical violence committed by a romantic partner, past-year physical fights anywhere, or past-year physical fights at school) and 2 types of sexual violence (lifetime forced intercourse, past-year sexual assault by a romantic partner). In 2017, participants were asked an additional question: whether they had experienced past-year sexual assault committed by anyone.

Outcome variables were dichotomized to indicate whether participants had experienced each form of violence 0 times or at least 1 time. The risks for each type of violence among sexual minority adolescents were quantified through descriptive statistics and logistic regression analysis after adjustment for the same confounders used in a previous analysis5: survey year, sex, age, race/ethnicity, English language proficiency, and grade level. Risk ratios were computed from the regression models using random draws from the variance-covariance matrix.5 Survey sample weight–adjusted analyses were conducted with the survey package in R, version 3.5.2 (R Foundation).6 Significance tests for regression analyses used 2-sided α = .05.


Of the 28 811 participants in the 2015 and 2017 YRBS, 87.1% reported their sexual orientation as heterosexual, 2.2% as gay or lesbian, 7.0% as bisexual, and 3.7% as not sure.

Twelve percent of sexual minority adolescents reported physical violence committed by a romantic partner, 27.6% engaged in a physical fight, and 11.1% engaged in a physical fight on school property (Table). Furthermore, 20.6% of sexual minority adolescents reported experiencing sexual assault, 18.0% reported experiencing forced intercourse, and 12.5% reported experiencing sexual assault by a romantic partner.

After adjusting for confounders, sexual minority adolescents were consistently more likely than their heterosexual counterparts to report physical and sexual violence, including physical violence committed by a romantic partner (adjusted risk ratio [aRR], 1.97; 95% CI, 1.65-2.34) and sexual assault committed by anyone (aRR, 2.10; 95% CI, 1.68-2.58) in the preceding 12 months. Bisexual sexual minority adolescents were at a particularly elevated risk for violence, including physical violence committed by a romantic partner (aRR, 2.22; 95% CI, 1.82-2.67) and sexual assault committed by anyone (aRR, 2.36; 95% CI, 1.76-3.10).

Sexual minority female adolescents were at an elevated risk of physical violence relative to the risk to heterosexual female adolescents, including engaging in a physical fight anywhere (aRR, 1.74; 95% CI, 1.53-1.96) and engaging in a fight on school property (aRR, 1.91; 95% CI, 1.49-2.43). Sexual minority male adolescents had elevated risks of sexual violence relative to the risks to heterosexual male adolescents, including the risk of sexual assault (aRR, 4.64; 95% CI, 2.97-6.84) and the risk of forced intercourse (aRR, 4.70; 95% CI, 3.40-6.32).


Sexual minority adolescents—particularly bisexual youth—are at an elevated risk for both physical and sexual violence. Given the substantial physical and emotional consequences of violence for those subjected to it and the large existing health disparities among sexual minority adolescents, addressing both physical and sexual violence against sexual minority adolescents should become a public health priority.

This study has some limitations. Self-reports are subject to misreporting and bias. Students who reported “not sure” may have been questioning their sexuality or unsure of the question. The YRBS does not collect information on transgender individuals; thus, we cannot assess their risk. This study was cross-sectional, and we cannot make causal claims about its findings. Although the YRBS is representative of US high school students, it may not be representative of US sexual minority high school students.

The results of our study suggest the existence of a crisis of violence against sexual minority adolescents. Researchers should work with policy makers and clinicians to design, implement, and assess interventions to reduce the risks and mitigate the harms of violence committed against sexual minority adolescents.

    Violence Against Sexual Minority Adolescents
    Michael McAleer, PhD(Econometrics),Queen's | Asia University, Taiwan
    The detailed, enlightening, and novel clinical analysis by experts on physical and sexual violence among sexual minority, specifically LGBQ, adolescents in the USA is disturbing in terms of public health hazards, as well as the criminally liable behaviour of the perpetrators of such violence.

    Public information on the prevalence of physical and sexual assault against sexual minority adults is generally available through many studies, but not for sexual minority adolescents.

    Consequently, the findings in the paper provide an urgent wake-up call for researchers, public policy decision makers, clinicians, and pediatricians to develop interventions to reduce the risks of
    violence committed against sexual minority adolescents.

    The pooled data were accessed from the National Youth Risk Behavior Survey (YRBS), conducted every 2 years by the US Centers for Disease Control and Prevention (CDC), for 2015 and 2017, and are based on anonymous self assessments.

    The questionnaires required self identification of sexual orientation as Lesbian, Gay or Bisexual, with "not sure" interpreted as Queer or Questioning (that is, still exploring one's sexual orientation), for the acronym LGBQ.

    Transgender and Intersexed (that is, with ambiguous biological sex characteristics) were not included in the questionnaire, which is surprising, as Transgender (though not Intersexed) has been included in LGBT since Gallup started tracking in 2012, every two years, the percentage of US adults identifying as LGBT (

    A direct comparison between adult LGBT (3.9% in 2015 and 4.5% in 2017) and adolescent LGBQ (12.9% based on pooled data for 2015 and 2017). is not strictly accurate, but is nevertheless instructive in terms of the apparent large differences between adult and adolescent self identification. 

    The important questionnaire that is conducted by the US CDC should expand the sexual minority classifications to include LGBTIQ adolescents to enable more accurate, targeted and robust public health interventions against unacceptable and elevated physical and sexual violence.
