COVID-19 exposure and diagnosis among college student drinkers: links to alcohol use behavior, motives, and context

The COVID-19 pandemic is a public health crisis. College student alcohol use is highly prevalent and primarily occurs in social settings where risk for COVID-19 transmission is heightened. This study explored the associations between alcohol use frequency, quantity, motives, and context with: (i) quarantine due to COVID-19 exposure and (ii) a positive diagnosis for COVID-19. A sample of n = 409 college student drinkers completed an online survey about their health and behaviors during the Fall 2020 semester. Since the start of the semester, 36% of students quarantined and 13% of students received a COVID-19 diagnosis. More frequent alcohol use was associated with increased odds of both quarantine and COVID-19 diagnosis. More frequent drinking for social motives was associated with increased likelihood of quarantine, and more frequent drinking for conformity motives was associated with increased likelihood of COVID-19 diagnosis. Participants who often drank alone or with a small group of friends were about half as likely to have quarantined, while those who often drank with a large group of friends were almost twice as likely to have quarantined. Participants who often drank in a bar or nightclub had almost three times the odds of a COVID-19 diagnosis. Frequent alcohol use and drinking for social and conformity motives and in certain contexts are linked to increased likelihood of COVID-19 exposure and diagnosis. Alcohol use prevention efforts, coupled with messaging to discourage large social gatherings in public places, might help to mitigate the spread of COVID-19 among college students.
