High-Risk Drinking in Midlife Before Versus During the COVID-19 Crisis: Longitudinal Evidence From the United Kingdom

INTRODUCTION: Emerging evidence suggests that the COVID-19 pandemic and associated lockdown restrictions may have influenced alcohol consumption. This study examines changes in high-risk alcohol consumption from before to during the COVID-19 crisis in an established cohort of middle-aged British adults. METHODS: Participants consisted of 3,358 middle-aged adults from the 1970 British Cohort Study who completed the Alcohol Use Disorders Identification Test for detecting hazardous drinkers in primary care settings in 2016–2018 (when aged 46–48 years) and May 2020 (aged 50 years). Multivariable logistic regression analysis was used to examine changes in high-risk drinking (scores of ≥5), and multinomial regression was used to compare responses with individual test items in 2016–2018 and May 2020. RESULTS: Among middle-aged British adults, high-risk drinking increased by 5.2 percentage points from 19.4% to 24.6% (p<0.001) between 2016–2018 and May 2020. The increase in high-risk drinking was not moderated by sex, marital status, educational attainment, the presence of a chronic illness, or the year the baseline survey was completed. The prevalence of drinking ≥4 times a week doubled from 12.5% to 26% from before to during the pandemic (p<0.001), and there was also evidence of an increase in the frequency of being unable to stop drinking. CONCLUSIONS: This study provides evidence linking the COVID-19 crisis and associated lockdown restrictions to an increase in high-risk drinking patterns and particularly frequent drinking in British adults. Potential long-term changes in drinking habits should be monitored following the emergence of the COVID-19 pandemic.
