Altered alcohol consumption during COVID-19 pandemic lockdown

Abstract

Background Since the onset of the COVID-19 pandemic in December 2019, many countries around the world have imposed lockdown measures in order to reduce virus spread. Social isolation is known to have a significant psychological impact, potentially triggering alcohol misuse in adults. In our study, we aimed to investigate the effect of COVID-19 lockdown measures on alcohol consumption in adults in Bavaria. Methods In this cross-sectional study, we enrolled 2067 participants, with 1961 young adults (mean age 23.3\u2009±\u20094.1) and 106 mature adults (mean age 66.7\u2009±\u20099.7). Participants were asked to complete a standardized questionnaire, semi-quantitatively evaluating the alcohol drinking behaviour before and during the pandemic lockdown. Results After implementation of lockdown, the alteration of alcohol consumption was significantly different between young and mature adults ( p \xa0<\u2009\xa00.001). Among young adults, 42% reported unchanged drinking behaviour compared to 76% in the mature adult group; 44% of young adults reported to drink less compared to only 7% of mature adults. An increase in alcohol consumption was only reported by 14% of young adults and 17% of mature adults. Interestingly, in the entire cohort, the change of alcohol intake was most pronounced among moderate drinkers (>\u20090 to <\u20095 drinks/week) in both age groups ( p \xa0<\u2009\xa00.001). Ordinal logistic regression revealed female sex, low BMI and younger age to be associated with a decrease in number of self-reported drinks/week. Conclusion The COVID-19 pandemic lockdown significantly affected alcohol drinking behaviour. Further studies exploring long-term effects on potential alcohol misuse and the relevance on public health are warranted. Trial registration The study was retrospectively registered at ClinicalTrials.gov ( NCT04361877 ) on April 24, 2020.
