Abstract
Alcohol's harms to others (AHTO) refers to the negative effects experienced by individuals other than the drinker. This study investigates the prevalence and risk factors of AHTOs among US college students (sophomores/juniors), based on the first national probability-based survey conducted in 20 years. We assessed AHTOs in the fall of 2021 from 1918 participants across 46 US schools, weighting the data to reflect the US undergraduate sophomore/junior population. We combined survey weights and prevalence estimates to approximate the number of sophomores/juniors in the US college population who experienced each AHTO. Once weighted, the sampling method was designed to be representative of sophomores/juniors. We used multivariate logistic regression with clustered standard errors to estimate the likelihood of each AHTO domain and any AHTO for demographic and behavioural risk and protective factors. Half (53.5%) of our sample reported experiencing at least one AHTO, which corresponds to nearly 6 million US sophomores/juniors. Students who were White; attended 4-year schools; identified as cisfemale or transgender, gender nonconforming, or 2+ identities; of higher socioeconomic status (as indicated by parent's highest level of education); lived with roommates; and/or participated in Greek organisations or intercollegiate athletics had a higher likelihood of AHTOs. Our findings demonstrate that AHTOs, including academic, physical and sexual harms, are prevalent on college campuses. These results suggest that colleges likely underestimate the impact of alcohol on their students. Therefore, broadening and strengthening campus and state-level policies and strategies to prevent and reduce these harms effectively are needed.
