Alcohol consumption during the COVID-19 pandemic in Europe: a large-scale cross-sectional study in 21 countries
Abstract
Aims: To investigate changes in alcohol consumption during the first months of the COVID-19 pandemic in Europe as well as its associations with income and experiences of distress related to the pandemic. Design: Cross-sectional on-line survey conducted between 24 April and 22 July 2020.
Setting: Twenty-one European countries. Participants: A total of 31 964 adults reporting past-year drinking.
Measurements: Changes in alcohol consumption were measured by asking respondents about changes over the previous month in their drinking frequency, the quantity they consumed and incidence of heavy episodic drinking events. Individual indicators were combined into an aggregated consumption-change score and scaled to a possible range of -1 to +1.
Using this score as the outcome, multi-level linear regressions tested changes in overall drinking, taking into account sampling weights and baseline alcohol consumption [Alcohol Use Disorder Identification Test (AUDIT-C)] and country of residence serving as random intercept. Similar models were conducted for each single consumption-change indicator.
Findings: The aggregated consumption-change score indicated an average decrease in alcohol consumption of -0.14 [95% confidence interval (CI) = -0.18, -0.10]. Statistically significant decreases in consumption were found in all countries, except Ireland (-0.08, 95% CI = -0.17, 0.01) and the United Kingdom (+0.10, 95% CI = 0.03, 0.17).
Decreases in drinking were mainly driven by a reduced frequency of heavy episodic drinking events (-0.17, 95% CI = -0.20, -0.14). Declines in consumption were less marked among those with low- or average incomes and those experiencing distress.
