Research Snapshot: Changes in alcohol consumption during the COVID-19 pandemic in Canada

What you need to know

There is evidence that large-scale disasters lead to emotional distress and increased substance use. Similar patterns have been observed during the COVID-19 pandemic. Alcohol is the most used substance among Canadians during the pandemic. The risk of alcohol-related harms can be experienced from both acute and longer-term consumption. Alcohol sales were designated as an essential service during COVID-19 in many Canadian jurisdictions, and comparable patterns have been observed in the United States, the United Kingdom, Poland and Australia.

Canadian researchers conducted a cross-sectional survey focusing on the impact of the COVID-19 pandemic on alcohol use and emotional well-being among New Brunswick and Nova Scotia adults. To date, research in this area has been limited, with no population-based Canadian studies. This study found that individuals who reported increased feelings of stress, loneliness and hope­lessness during the COVID-19 pandemic were more likely to report increased drinking frequency.

What is this research about?

Individuals often use alcohol as a coping mechanism during times of stress. Studies have shown that emotional distress is associated with increased drinking frequency in both men and women. New and emerging evidence is now suggesting that alcohol consumption has increased during the COVID-19 pandemic. This increase has potential long-term social and economic costs for individuals, communities and society.

Drawing on data from a cross-sectional survey of adults in New Brunswick and Nova Scotia, this study examined:

  1. changes in alcohol consumption during the COVID-19 pandemic
  2. an association between drinking more frequently during the COVID-19 pandemic and increased feelings of stress, loneliness and hopelessness
  3. differences based on gender.

What did the researchers do?

The researchers conducted a cross-sectional survey of adults living in New Brunswick and Nova Scotia. They collected data from 2,000 individuals aged 19 and older in two phases. In the first phase, 500 respondents were randomly selected to be surveyed online, and researchers targeted those with Internet access, including hard-to-reach target groups. In the second phase, 1,500 respondents were selected through telephone, and researchers targeted those regions not captured or underrepresented in the online survey. A Canadian market research company administered the survey.

The researchers captured data on the following factors:

What did the researchers find?

Of those surveyed, the average age of the participants was 50 years, and 52% identified as women.

The researchers found that:  

Overall, the researchers found increased feelings of stress, loneliness and hopelessness were all associated with drinking more frequently during the pandemic. Furthermore, respondents who reported more frequent drinking since the start of the pandemic were, on average, younger and more likely to report fair or poor mental health and higher rates of stress, loneliness and hopelessness.

Limitations of the research

The researchers note that their study had several limitations. Data were only collected in New Brunswick and Nova Scotia, and may not be generalizable to other regions of Canada. In addition, survey responses were based on individual experiences at a specific point in time, so the researchers could not determine any cause-and-effect relationship between emotional distress and increased frequency of drinking during the pandemic. Responses were drawn from self-reports, which may have led to response bias, including social desirability bias and recall bias. Also, the study had a low response rate, which may have led to non-response bias.

How can you use this research?

The researchers note that more research is needed to help develop alcohol control policies and public health interventions to understand the association between several factors such as mental health, drinking frequency and alcohol availability that increased alcohol consumption throughout the pandemic and beyond. They recommend that future public health measures should include warnings against emotionally motivated alcohol consumption and other high-risk drinking behaviours.
