The pandemic has seen a surge in harmful binge drinking as adults are forced to work from home.
A new study has warned levels of drinking among adults increases the longer they spend at home in lockdown, according to the study by The University of Texas Health Science Centre at Houston School of Public Health, Dallas Campus.
The research, based on a survey of nearly 2,000 over-18s in the US and peer-reviewed in the American Journal of Drug and Alcohol Abuse is the first to highlight the relationship nationally between hazardous drinking and life stresses triggered by the COVID-19 pandemic and the associated “lockdowns”.
The findings showed the odds of heavy alcohol consumption among binge drinkers – those who, within two hours, consumed five or more drinks for men and four and above for women – rose an extra 19% for every week of lockdown.
The odds of increased alcohol intake overall for binge drinkers was more than double that of people who did not drink excessively (60% vs 28%), especially those with depression or a history of the disease.
It warned that:
- During the pandemic, binge drinkers on average drank four drinks per occasion, compared to two drinks among non-binge drinkers.
- Participants who drank at harmful levels during the pandemic would consume seven drinks maximum on one occasion. This is compared to a maximum of two per session during the pandemic for those who did not.
- Living with children in lockdown minimally reduced the odds (by 26%) of turning to the bottle for people in general.
The researchers are now calling for new intervention and prevention strategies for people in isolation at risk of hazardous drinking. Otherwise, they warned there could be long-lasting health consequences.
“Increased time spent at home is a life stressor that impacts drinking and the Covid-19 pandemic may have exacerbated this stress,” says Sitara Weerakoon, a PhD candidate from UTHealth. “Future research should consider the potential for depressive symptoms acting as a moderator (a factor that changes the impact) in the relation between the time spent under a shelter-in-place mandate (lockdown) and binge drinking.
“Additional research is (also) needed to develop best treatment for people with substance use disorders who may be more susceptible to adverse health outcomes.”
The study aimed to identify a link between COVID-19-related stress factors and changes in alcohol consumption and binge drinking since the pandemic began.
The data was from an online survey completed by 1,982 adults from mid-March to mid-April, which coincided with the first US state-wide stay-at-home order on 19 March. The average age of participants was 42 and the majority were white (89%) and female (69%).
On average, every respondent had been in lockdown for four weeks, and spent 21 hours a day at home, with the majority (72%) not leaving for work.
Overall, nearly a third (32%) of participants reported binge drinking during the pandemic with binge drinkers increasing their intake. However, non-binge drinkers consumed about the same amount of alcohol than before lockdown.
Limitations of the study include the survey data being self-reported, and the fact the question on binge-drinking did not specify a time within which the alcohol was consumed.
In addition, the majority (70%) of participants were relatively high earners, a factor already associated with hazardous alcohol use. The authors said future research is needed in a more ‘generalisable population’.
