Impact of the COVID-19 pandemic on alcohol consumption in young adults: A systematic review.

Abstract

Objectives: The COVID-19 pandemic caused unprecedented restrictions, leading to differences in the frequency and patterns of alcohol consumption, especially among young adults. This systematic review aims to investigate the overall evidence concerning changes in alcohol consumption in this period.

Study design: Systematic review.

Methods: Adhering to PRISMA and SWiM guidelines, this study's review protocol is registered in PROSPERO (CRD42023464591). The studies research was carried out in PubMed, Scopus, and Web of Science. Inclusion criteria involved observational studies focusing on participants aged 18 to 35, exploring alcohol consumption during at least the first wave of COVID-19, and publications in English or Spanish.

Results: A total of 28 studies conducted in different countries were included, European (18), North American (9), and Latin American (1). Although in many studies the overall prevalence of alcohol use was reduced, it was mainly among occasional users, in which the main motivation was the lack of social contact. It was exposed that participants with a high risk of problematic use increased their alcohol consumption, showing associated factors such as poor mental health, depressive symptoms, stress, and coping motivations. Males generally exhibited a higher risk of problem use and risky behaviours than females.

Conclusions: During COVID-19, youth alcohol consumption decreased overall, especially among social drinkers, but increased among high-risk users due to factors like distress and loneliness. Similar trends during other disasters emphasize the importance of addressing high-risk drinking in disaster planning. Also, preventing high-risk drinking from adolescence and youth could be helpful in reducing the global burden and impact of alcohol consumption.
