Safety and Predictors of Sexual Minority Youth Carrying Weapons.

Prior research has revealed sexual minority youth are more likely to carry weapons both outside of and within school. However, to date, no study has examined the degree to which bullying and harassment is associated with weapon carrying among sexual minority youth. We utilized the Youth Risk Behavior Survey to examine the prevalence and likelihood of carrying weapons by sexual identity, adjusting for adverse experiences. From the Youth Risk Behavior Survey 2009-2015, we examined self-report of adverse experiences (e.g., being bullied, skipping school due to fear for personal safety) and performed Logistic regressions to estimate the odds of carrying a weapon and were adjusted to include demographics and adverse experiences. When surveyed by sexual identity, 14.0% of heterosexual, 21.8% of gay/lesbian, 18.5% of bisexual, and 17.4% of "not sure" students reported carrying a weapon in the past 30 days. Odds of carrying a weapon were significantly increased for youth who skipped school due to feeling unsafe at school, had ever been threatened with a weapon in the past year, and had ever been in a physical fight. Compared to heterosexual female peers, sexual minority women had increased odds of carrying a weapon. Pediatricians should recognize that experiencing bullying and feeling unsafe are associated with weapon carrying, particularly among sexual minorities. Pediatricians and professionals who work with youth should recognize that reported experiences of bullying may not be the most salient indicator of risk for weapon carrying among all youth, and that other fears of or experiences with bullying are crucial to screen for among sexual minorities in particular.

Student characteristics and substance use as predictors of self-reported HIV testing: the youth risk behavior survey (YRBS) 2013-2015.

Many adolescents and young adults (AYAs; ages 13-24) are unaware of their HIV status despite participating in behavior that places them at risk for contracting HIV. This study examined possible predictors of self-reported HIV testing for high school students (grades 9-12) who completed the Youth Risk Behavior Survey (YRBS). Three sex-stratified, stepwise multivariable logistic models were used to estimate odds of having received a HIV test being associated with student characteristics and substance use. The likelihood of being tested for HIV was associated with students who were a racial/ethnic minority and age 18 and older. HIV testing was also associated with male students who reported same sex partners (males) or same sex partners (males) and different sex partners (females). Female students who reported same sex partners (females) and different sex partners (males) were more likely to have been tested for HIV. Male and female students were more likely to have been tested for HIV if they reported illicit drug and/or marijuana use, while prescription drug use was also associated with HIV testing for female students. Knowledge of the predictors of HIV testing for adolescents can guide efforts for the effective scale up of testing for this vulnerable population.

Associations Between LGBTQ-Affirming School Climate and Intimate Partner Violence Victimization Among Adolescents.

Intimate partner violence (IPV) impacts sexual minority adolescents at rates equal to or greater than the rate it impacts heterosexual adolescents. We investigated whether reports of physical and sexual IPV were less frequent in school jurisdictions with more affirming climates for lesbian, gay, bisexual, transgender, and queer (LGBTQ) students; and whether these associations varied for sexual orientation subgroups. We combined student-level data from the 2015 Youth Risk Behavior Surveys on demographics and experiences with physical and sexual IPV with jurisdiction-level data from the 2014 School Health Profiles on LGBTQ-affirming school climate. Multilevel logistic regression models examined associations between LGBTQ-affirming school climates and IPV. We stratified our data by sex and examined whether these associations differed by sexual orientation subgroups using cross-level interaction terms between school climate and sexual orientation (assessed via sexual identity and behavior). Sexual minority youth were more likely to report experiencing past-year physical and sexual IPV than their heterosexual counterparts. Attending schools with more LGBTQ-affirming climates reduced the likelihood of reporting physical IPV, but not sexual IPV, for female students. More LGBTQ-affirming school climates increased risk for sexual IPV among gay male students. Establishing LGBTQ-affirming school climates may reduce physical IPV for female students, but may have unintended consequences on sexual IPV prevalence for gay male students. More work is necessary to ensure that these climates are affirming for all sexual minority students and to address sexual violence prevention.

Differential Decline in Illicit Drug Use by Sexual Identity Among United States High School Students, 2005-2017.

Purpose: Adolescent drug use remains a significant public health concern. Sexual minority youth (SMY) are at elevated risk for illicit drug use compared with their heterosexual peers. We investigated this pattern at the national level, exploring whether trends and disparities in drug use vary over time and by sexual identity. Methods: This study used Youth Risk Behavior Survey (YRBS) data, which were collected at seven time points from 2005 to 2017. Trends and disparities over time in the use of five drugs, as well as any drug use, were analyzed by self-reported sexual identity. Results: The results demonstrated a general decrease in drug use behaviors from 2005 to 2017. The greatest number of significant decreases was among heterosexual and bisexual students; the fewest were among gay and lesbian students. Disparities between heterosexual youth and SMY persisted across years, and were greater for gay and lesbian students in 2017 than for bisexual and not-sure youth. Conclusions: Our results represent the most comprehensive analysis of recent trends in drug use by sexual identity to date. Disparities in drug use remained significant despite overall downward trends within our sample. The significant decreases among bisexual students are not readily explained. We emphasize the need for ongoing research in this area, particularly given the currently volatile social position of sexual minority populations in the United States, and for culturally responsive and trauma-informed responses to SMY drug use.

Alcohol Use and Suicidality by Sexual Orientation Among U.S. Youth, 2009-2017.

INTRODUCTION: Alcohol use and suicidality remain serious risks for U.S. youth. Research has established that disparities exist in these outcomes between heterosexual and sexual minority youth. However, research into the associations between alcohol use and suicidality has yet to consider the differential role of sexual orientation. METHODS: Using a pooled, diverse sample from the 2009-2017 Youth Risk Behavior Survey, associations of alcohol use and suicidality by sex and sexual orientation, and changes in these outcomes over time, were investigated. Analyses were conducted in 2019. RESULTS: Suicidality was highest among nonheterosexuals, who ranged from twofold to sevenfold higher odds to report suicidality across all time points, with the most striking disparities among male sexual minority youth. Rates among all students remained stable or increased over time; notable exceptions included a decrease in suicide attempts among bisexual students. Among all students, current alcohol use was associated with elevated levels of suicidality. For female students, the association between drinking and suicidality did not significantly differ by sexual identity; for male students, it was significant regardless of sexual identity and most pronounced among not sure youth. CONCLUSIONS: These results emphasize the need for additional research into the relationship between contemporaneous alcohol use and suicidality, with attention to differences based on sex, sexual orientation, and other factors that may impact these relationships. There is a particular need for research to examine the temporal nature of the association such that evidence-informed, high-impact interventions can be developed to improve suicidality outcomes among sexual minority youth.

Changes in Victimization Risk and Disparities for Heterosexual and Sexual Minority Youth: Trends From 2009 to 2017.

PURPOSE: The aim of this study was to identify sex-stratified trends in victimization risk specific to heterosexual, lesbian, gay, bisexual, and questioning youth while considering changes in sexual orientation-disparities from 2009 to 2017. METHODS: Youth Risk Behavior Survey (YRBS) data collected biennially (five waves; 2009-2017) were pooled across 56 jurisdictions and 454,715 students for one of the most nationally representative samples of heterosexual and sexual minority youth to date. We analyzed a seven-item victimization risk assessment using the Centers for Disease Control and Prevention's recommended trend analysis approach. We used logistic regression with year-by-identity interactions to test whether sexual orientation-based disparities widened, narrowed, or were maintained over time. RESULTS: Victimization risk declined significantly for male and female bisexual and questioning youth, lesbian, gay, and heterosexual youth. Disparities narrowed between bisexual, questioning, and lesbian females and heterosexual females and between bisexual and heterosexual males. Nevertheless, sexual orientation-based disparities remained significant for all sexual minority youth in 2017. CONCLUSIONS: Distinct patterns of change in victimization risk for specific groups of sexual minority youth underscore the need to consider variability within sexual minority youth communities; treating them as a singular group could mask nuanced disparities. Some of the relatively small decreases in victimization risk also suggest the need for interventions to address a more comprehensive set of victimization-related risks beyond bullying and needed efforts that are not limited to the immediate school context.

Sexual Orientation Disparities in Pregnancy Risk Behaviors and Pregnancy Among Sexually Active Teenage Girls: Updates from the Youth Risk Behavior Survey.

Purpose: The purpose of this study was to determine the extent to which sexual identity and/or sexual behaviors were associated with pregnancy risk factors (condom use, alcohol or other drug use before sex, and World Health Organization [WHO] Tier 1 [i.e., intrauterine device, implant] or Tier 2 [i.e., injectable, pill, patch, or ring] contraception use) and teen pregnancy among female high school students who reported having a sexual relationship with a male partner. Methods: Data were from the Youth Risk Behavior Survey (YRBS; 2005-2015) (n = 63,313). Logistic regression was used to analyze sexual identity and behavior disparities in pregnancy risk behaviors and teen pregnancy. Interactions between sexual identity and behavior were also tested. All models adjusted for the YRBS complex sampling frame. Results: Girls who reported being unsure of their sexual identity were less likely to use condoms or a WHO Tier 1 or Tier 2 contraceptive method at last sex, and more likely to report alcohol or other drug use at last sex than heterosexual girls. Girls who identified as lesbian were also less likely to use a condom at last sex, and girls who reported both male and female sexual partners were more likely to report alcohol or other drug use and less likely to use condoms at last sex. Girls who identified as bisexual were more likely to report pregnancy during teenage years than girls who identified as heterosexual. Conclusion: Our results support the need to assess both sexual identity and sexual behavior in research on teen pregnancy and pregnancy risk. Furthermore, the finding that girls who were unsure of their sexual identity showed heightened risk highlights the need for additional research that includes this group.

Trends in Alcohol Use Behaviors by Sexual Identity and Behavior Among High School Students, 2007-2017.

PURPOSE: Certain groups, particularly sexual minority youth, demonstrate notable disparities in alcohol use risk. Assessing trends in alcohol use behaviors by sexual orientation over time is therefore important to the epidemiologic study of adolescent health equity. METHODS: We analyzed age at first drink, lifetime drinking behavior, current drinking, and binge drinking in a large, national sample of high school youth across six time points, beginning in 2007 and biennially through 2017. We assessed trends by sex, sexual identity, and sexual behavior, controlling for race/ethnicity and age. RESULTS: Our results demonstrated that, although overall alcohol use is decreasing among youth, disparities between heterosexual and sexual minority youth remain significant. The largest decreases were seen in current alcohol use among lesbian youth, which fell from a prevalence of 56.1% in 2007 to 38.9% in 2017, and among bisexual females (64.3% in 2007 to 41.1% in 2017). Despite this, alcohol use behaviors were still elevated among lesbian and bisexual female youth compared with heterosexual sex-matched counterparts. Heterosexual-identified male students saw significant decreases in alcohol use, whereas most alcohol use behaviors among sexual minority males decreased but not to a statistically significant degree, with the exception of binge drinking among those who identified as gay (2007: 36.0% to 2017: 12.6%) and bisexual (2007: 24.7% to 2017: 11.6%). Results by sexual behavior are presented within. CONCLUSIONS: Sexual minority youth continued to demonstrate markedly high prevalence of alcohol use behaviors compared with heterosexual peers across all time points. Downward trends in alcohol use may thus mask serious population health risks if not adequately explored. Research and health promotion efforts must consider sexual minority orientation to avoid incomplete or inaccurate representation of findings.

Correction to: Sexual Identity and Behavior Among U.S. High School Students, 2005-2015.

The following correction should be noted to the caption of Fig. 1 in this article.

Sexual Identity and Behavior Among U.S. High School Students, 2005-2015.

Sexual orientation is a multidimensional construct which is increasingly recognized as an important demographic characteristic in population health research. For this study, weighted Youth Risk Behavior Survey data were pooled across 47 jurisdictions biennially from 2005 to 2015, resulting in a national sample of 98 jurisdiction-years (344,815 students). Respondents were a median of 15.5 years, 49.9% male, and 48.8% White. Sexual identity and behavior trends from 2005 to 2015 were assessed with logistic regression analysis. Overall, 13.9% of females and 7.0% of males identified as lesbian, gay, bisexual (LGB), or not sure, while 9.1% of females and 4.2% of males indicated both same-and-different-sex behavior or same-sex behavior. In total, 17.0% of female and 8.5% of male youth reported non-heterosexual (LGB or not sure) sexual identity, same-sex sexual behavior, or both. LGB youth were approximately twice as likely as other youth to report lifetime sexual behavior. White and Asian youth were less likely to report non-heterosexual identity and/or have engaged in same-sex sexual behaviors than youth of other races/ethnicities. Prevalence of non-heterosexual identities increased over time for both sexes, but only female youth reported significantly more same-sex behavior over time. This is the first study to simultaneously assess adolescent sexual identity and behavior over time within a national dataset. These findings are critical for understanding the sexual health needs of adolescents and for informing sexual health policy and practice.

Racial/Ethnic Differences in Mental Health, Substance Use, and Bullying Victimization Among Self-Identified Bisexual High School-Aged Youth.

Purpose: Sexual minority youth are at increased risk for mental health problems and substance use, and accumulating evidence indicates that bisexual youth are at greatest risk. However, bisexual youth are not a homogenous group and scholars have called for greater attention to the intersections of multiple marginalized identities. As such, we examined racial/ethnic differences in mental health (sadness/hopelessness and suicidal ideation), substance use (cigarette use, binge drinking, marijuana use, and other illicit drug use), and bullying (in-person and electronic) among self-identified bisexual high school-aged youth (overall and by sex). Method: Data from the local versions of the Youth Risk Behavior Survey were pooled across jurisdictions and years (2011-2015), resulting in an analytic sample of 18,515 bisexual youth who were racially/ethnically diverse. Results: Black and Hispanic bisexual youth were less likely to report in-person and electronic bullying than White bisexual youth. In addition, Black bisexual youth were less likely to report sadness/hopelessness and suicidal ideation than White, Hispanic, and Other race/ethnicity bisexual youth. Black bisexual female youth were also less likely to report cigarette use, binge drinking, and other illicit drug use than White bisexual female youth. In contrast to most of our findings, Black bisexual youth were more likely to report marijuana use than White bisexual youth. Most of the significant racial/ethnic differences in mental health and substance use remained significant after controlling for bullying. Conclusion: These findings highlight the heterogeneity of bisexual youth and the need to consider multiple marginalized identities to understand the health disparities affecting this diverse population.

Cigarette Smoking Disparities Between Sexual Minority and Heterosexual Youth.

BACKGROUND: Using a population-based sample of youth, we examined rates of cigarette use and trends in cigarette use disparities between heterosexual youth and 3 subgroups of sexual minority youth (SMY) (ie, lesbian or gay, bisexual, and unsure) from 2005 to 2015. METHODS: Data are from 6 cohorts of the Youth Risk Behavior Survey, a national, biennial, school-based survey of ninth- to 12th-grade students in the United States (n = 404 583). Sex-stratified analyses conducted in 2017 examined trends in 2 cigarette-related behaviors: lifetime cigarette use and heavy cigarette use (20+ days in the past 30). RESULTS: Disparities in lifetime cigarette use between lesbian and heterosexual girls were statistically smaller in 2015 relative to 2005 (adjusted odds ratio [aOR] 0.29; 95% confidence interval [CI] 0.12-0.75; P = .011). Sexual orientation disparities in heavy use were narrower for bisexual boys in 2015 compared with 2005 (aOR 0.39; 95% CI 0.17-0.90; P = .028). Girls and boys unsure of their sexual identity had wider disparities in heavy use in 2015 (aOR 3.85; 95% CI 1.39-11.10; P = .009) relative to 2005 (aOR 2.44; 95% CI 1.22-5.00; P = .012). CONCLUSIONS: SMY remain at greater risk for cigarette-related behaviors despite greater acceptance of lesbian, gay, and bisexual people in the United States. Focused policies and programs aimed at reducing rates of SMY cigarette use are warranted, particularly for youth questioning their sexual identity.

Alcohol Use and Disordered Eating in a US Sample of Heterosexual and Sexual Minority Adolescents.

OBJECTIVE: To expand knowledge of co-occurring alcohol use and disordered eating behaviors (DEB) among sexual minority (ie, nonheterosexual) youth. METHOD: Using pooled 2009 to 2015 US Youth Risk Behavior Surveys (322,687 students; 7.3% lesbian, gay, bisexual), multivariable logistic regression models examined the following: (1) associations of age of onset of drinking and past month binge drinking with past year DEB (fasting, diet pill use, purging, steroid use); and (2) effect modification by sexual orientation. RESULTS: Alcohol use and sexual minority identity were independently associated with elevated odds for diet pill use and purging among female adolescents, and with fasting and steroid use among male adolescents. Odds of fasting increased with greater frequency of monthly binge drinking among heterosexual adolescent female youth, and odds of diet pill use increased with greater frequency of monthly binge drinking among heterosexual adolescent male youth. DEB prevalence was particularly pronounced among adolescents who binge drank and who were not sure of their sexual orientation identity. Among male adolescents not sure of their sexual orientation identity, those who binge drank more than 1 day in the past month had 8.63 to 23.62 times the odds of using diet pills relative to those who did not binge drink, and 13.37 to 26.42 times the odds of purging relative to those who did not binge drink. CONCLUSION: More research is needed on psychosocial factors underlying alcohol use and DEB in youth of all sexual orientations.

Sexual Minority Youth at Risk of Early and Persistent Alcohol, Tobacco, and Marijuana Use.

The current study sought to examine substance use disparities among sexual minority youth. The current subsample of 348,175 students participated in the Youth Risk Behavior Surveillance System (YRBSS) study from years 2005 to 2015 (biennially) in jurisdictions that asked at least one question about sexual minority status. Latent class analysis was used to identify implicit classes of sexual minority youth, based on respondents' sexual identity and sexual behavior. Sex-stratified regression models were run to determine the association between class membership and age of onset and persistent use of alcohol, tobacco, and marijuana. Findings showed that sexual minority female subgroups were primarily distinguished by sexual identity (e.g., "lesbian," "bisexual"), whereas sexual minority male subgroups were primarily distinguished by sexual behavior. Female lesbian and bisexual youth were at risk of initiating substance use at younger ages and, among lifetime users, were more likely to persist in their tobacco and marijuana use over time, relative to sexually active female heterosexual youth. Among lifetime users, male youth with partners of both sexes were at greater risk of persistent use of alcohol, tobacco, and marijuana over time and earlier ages of first use. Recommendations for intervention and prevention programs geared toward reducing sexual minority youth substance use are provided.

Bias From Potentially Mischievous Responders on Large-Scale Estimates of Lesbian, Gay, Bisexual, or Questioning (LGBQ)-Heterosexual Youth Health Disparities.

OBJECTIVES: To determine how sensitive estimates of lesbian, gay, bisexual, or questioning (LGBQ)-heterosexual youth health disparities are to the presence of potentially mischievous responders. METHODS: We used US data from the 2015 Youth Risk Behavior Survey, pooled across jurisdictions that included a question about sexual identity for a total sample of 148 960 students. We used boosted regressions (a machine-learning technique) to identify unusual patterns of responses to 7 screener items presumably unrelated to LGBQ identification, which generated an index of suspected mischievousness. We estimated LGBQ-heterosexual youth disparities on 20 health outcomes; then we removed 1% of suspected mischievous responders at a time and re-estimated disparities to assess the robustness of original estimates. RESULTS: Accounting for suspected mischievousness reduced estimates of the average LGBQ-heterosexual youth health disparity by up to 46% for boys and 23% for girls; however, screening did not affect all outcomes equally. Drug- and alcohol-related disparities were most affected, particularly among boys, but bullying and suicidal ideation were unaffected. CONCLUSIONS: Including screener items in public health data sets and performing rigorous sensitivity analyses can support the validity of youth health estimates.

Risk factors for diabetes are higher among non-heterosexual US high-school students.

Low physical activity (PA), high sedentary behavior (SB), and overweight and obesity have been shown to associate with increased Type 2 diabetes risk among adolescents. We investigated PA, SB, and overweight and obesity among Youth Risk Behavior Survey (YRBS) respondents to determine if non-heterosexual youth may be at increased diabetes risk compared to heterosexual youth. Weighted city and state YRBS data were pooled across 44 jurisdictions biennially from 2009 to 2015, resulting in a sample size of 350 673 students. Overall, 88.4% identified as heterosexual, 2.1% as gay or lesbian, 5.7% as bisexual, and 3.7% as unsure. With the exception of lesbian female students, after adjusting for age, race/ethnicity, body mass index, and survey year, all non-heterosexual youth reported significantly fewer days per week of PA compared to their sex-matched heterosexual counterparts. Similarly, compared to heterosexual female youth, bisexual and not sure female youth reported significantly more hours per day of SB. These PA and SB findings remained significant after adjustment for depressive symptoms and in-school bullying among bisexual female youth only. In fully adjusted models, lesbian students were 1.85 times more likely to be overweight and lesbian, bisexual, and not sure female youth were 1.55 to 2.07 times more likely to be obese than heterosexual female students. No significant differences in SB, overweight, or obesity were found among gay, bisexual, or unsure male youth compared to heterosexual male youth. Non-heterosexual youth may be at increased risk for developing type 2 diabetes mellitus compared to heterosexual youth. Future studies should characterize diabetes prevalence among non-heterosexual youth.

Condom and Substance Use at Last Sex: Differences between MSMO and MSWO High School Youth.

HIV disproportionately impacts youth, particularly young men who have sex with men (YMSM), a population that includes subgroups of young men who have sex with men only (YMSMO) and young men who have sex with men and women (YMSMW). In 2015, among male youth, 92% of new HIV diagnoses were among YMSM. The reasons why YMSM are disproportionately at risk for HIV acquisition, however, remain incompletely explored. We performed event-level analyses to compare how the frequency of condom use, drug and/or alcohol use at last sex differed among YMSMO and YMSWO (young men who have sex with women only) over a ten-year period from 2005⁻2015 within the Youth Risk Behavior Survey (YRBS). YMSMO were less likely to use condoms at last sex compared to YMSWO. However, no substance use differences at last sexual encounter were detected. From 2005⁻2015, reported condom use at last sex significantly declined for both YMSMO and YMSWO, though the decline for YMSMO was more notable. While there were no significant differences in alcohol and substance use at last sex over the same ten-year period for YMSMO, YMSWO experienced a slight but significant decrease in reported alcohol and substance use. These event-level analyses provide evidence that YMSMO, similar to adult MSMO, may engage in riskier sexual behaviors compared to YMSWO, findings which may partially explain the increased burden of HIV in this population. Future work should investigate how different patterns of event-level HIV risk behaviors vary over time among YMSMO, YMSWO, and YMSMW, and are tied to HIV incidence among these groups.

Sexual orientation disparities in prescription drug misuse among a nationally representative sample of adolescents: Prevalence and correlates.

OBJECTIVE: Sexual minority adolescents (SMA) may be at disproportionate risk for misusing prescription psychotropic medications compared to their heterosexual peers. However, generalizable studies specific to this age group are lacking. The current study aimed to describe the prevalence of sexual orientation disparities in prescription drug misuse among a nationally representative sample of adolescents as well as to examine key correlates of misuse. METHOD: Using data from the National Youth Risk Behavior Survey, we conducted stepwise multivariable weighted logistic regressions, sequentially controlling for demographics, experiences of victimization, mental health, and other illicit substance use. RESULTS: Adjusting for grade and race/ethnicity, female SMA and gay and unsure males had significantly elevated odds of ever misusing a prescription drug compared to heterosexual adolescents (ORs from 1.7-2.5). Most sexual orientation disparities among females remained significant with the addition of victimization and mental health covariates but attenuated completely after controlling for other illicit drug use. The effect for unsure males attenuated when victimization variables were included, but the effect for gay males remained significant through the final model. Controlling for other illicit drug use, mental health variables remained significant correlates for females whereas only forced sex was significant for males. CONCLUSION: These results suggest experiences of victimization and mental health partially account for the disparities in prescription drug misuse between SMA and heterosexual adolescents, and their effects may differ by sex. A combination of structural, individual coping, and universal drug prevention approaches should be used to make the largest impact on reducing these disparities.

Victimization as a mediator of alcohol use disparities between sexual minority subgroups and sexual majority youth using the 2015 National Youth Risk Behavior Survey.

BACKGROUND: Alcohol use among underage youth is a significant public health concern. According to the National Institute on Alcohol Abuse and Alcoholism, alcohol is the "drug of choice" among adolescents, meaning more youth use and abuse alcohol than any other substance. Prevalence of alcohol use is disproportionately higher among sexual minority youth (SMY) than among their heterosexual peers. We examined sexual identity and sexual behavior disparities in alcohol use, and the mediational role of bullying in a sample of high school students. METHODS: Data from the 2015 National Youth Risk Behavior Survey were used to assess the association between sexual minority status (identity and behavior) and alcohol use with weighted logistic regression. Due to well-documented differences between males and females, we stratified models by gender. Physical and cyberbullying were examined as mediators of the relationship between sexual minority status and alcohol use. RESULTS: We detected associations between certain subgroups of sexual minority youth and alcohol use across all four drinking variables (ever drank alcohol, age at first drink, current alcohol use, and binge drinking). Most of these associations were found among bisexual-identified youth and students with both male and female sexual partners; these individuals had up to twice the odds of engaging in alcohol use behaviors when compared with sexual majority students. Associations were strongest among females. Bullying mediated sexual minority status and alcohol use only among bisexual females. CONCLUSIONS: As disparities in alcohol use differ by gender, sexual identity, and sexual behavior, interventions should be targeted accordingly.
