Binge Drinking Disparities by Grade, Race and Ethnicity, Sexual Orientation, and Gender Identity

Binge drinking disparities between sexual and gender minority (SGM) students and their heterosexual, cisgender peers are well-established. Data limitations have precluded understandings of whether the onset and progression of these disparities differ by grade. Additionally, little is known about whether and how SGM-related binge drinking varies across groups of students coincidingly defined by sexual orientation or gender identity (SOGI), race, and ethnicity. In the current study, we used a large, statewide sample of secondary school students in California to describe the prevalence of binge drinking among subgroups of adolescents at the intersections of grade, race and ethnicity, and SOGI.

Data were from the 2017-2019 cycle of the California Healthy Kids Survey, one of the largest statewide cross-sectional surveys of secondary school students in the United States (n = 925 744). We described the grade-specific prevalence rates of past 30-day binge drinking by (1) grade level, (2) race and ethnicity, and (3) SOGI. Predicted probabilities estimated adjusted percentages of students' binge drinking by subgroups.

SGM-related binge drinking differences were present early in secondary school. Several subgroups of SGM adolescents with minoritized racial and ethnic identities reported higher binge drinking rates relative to their same-grade, white, non-SGM peers.

Prevention and intervention programs must consider developmentally- and culturally-informed strategies to most effectively promote health among minoritized students.
