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.
