Drinking, Social Abstaining, and Refusing Invitations: Demographic Differences Persist across College.
BACKGROUND
Alcohol use and misuse are prevalent on many college campuses. The current study examined participation in college environments where alcohol is present and being consumed. We documented students' alcohol consumption, social abstaining (i.e., attending an alcohol-present event, but not drinking), and refusing invitations to drinking events. We tested for differences by parental education, immigrant status, race-ethnicity, and gender. We charted longitudinal change across college.


METHODS
First-year students attending a large public US university (n=681, 18% first generation college student, 16% first generation immigrant, 73% racial-ethnic minority group member, 51% women) were recruited and followed longitudinally for seven semesters. Each semester, students completed up to 14 daily surveys; responses were aggregated to the semester level (n=4,267).


RESULTS
Multi-level logistic regression models demonstrated that first generation college students were less likely to drink and refuse invitations to drinking events than students with a college educated parent (AORs .66, .72, respectively). Similarly, first generation immigrants were less likely to drink, socially abstain, and refuse invitations (AORs .58-.73). Compared to White students, Black and Asian American students were less likely to drink (AORs .55, .53) and refuse invitations to drinking events (AORs .68, .66). The proportion of days spent drinking increased across college and refusing invitations was the most common at the start and end of college.


CONCLUSION
First generation college students, first generation immigrant students, and Black and Asian students participated less in pro-drinking environments during college. These findings indicate that on drinking and non-drinking days students' participation in alcohol-present situations differed by background. Furthermore, our results indicate that the students who are most likely to refuse invitations to drinking events are the same students who drink most frequently.
