Study explores pandemic-related shifts in alcohol sales across 16 US states

An evaluation of information from 16 U.S. states means that the primary few months of the COVID-19 pandemic noticed will increase in wine and spirit gross sales, accompanied by notable modifications within the relationship between alcohol gross sales and other people’s visits to companies that promote alcohol.

College at Buffalo researchers Yingjie Hu, Brian M. Quigley and Dane Taylor current these findings within the open-access journal PLOS ONE on Dec. 15. The workforce notes that developments diverse by state.

After U.S. states applied stay-at-home orders and different restrictions to cut back the unfold of COVID-19 in March 2020, anecdotes urged a rise in alcohol gross sales. Nonetheless, data-driven investigations into whether or not alcohol gross sales and use did certainly improve have produced combined outcomes.

To assist make clear the potential influence of COVID-19 lockdowns and different social distancing measures on the dynamics of alcohol gross sales, Hu and colleagues carried out an evaluation of related knowledge from 16 U.S. states, evaluating the interval from March to June 2020 to the identical interval in 2018 and 2019.

“Anonymized human mobility knowledge and geospatial evaluation assist us perceive how folks’s visiting habits to alcohol shops modified throughout the stay-at-home interval of COVID-19, and the way such habits change diverse throughout completely different geographic areas,” says Hu, Ph.D., an assistant professor of geography within the UB Faculty of Arts and Sciences.

“Understanding how alcohol buy habits is modified by occasions reminiscent of COVID is essential as a result of heavy alcohol use is understood to be related to quite a few social issues, particularly inside the residence,” says Quigley, Ph.D., analysis assistant professor of drugs within the Jacobs Faculty of Medication and Biomedical Sciences at UB and the UB Medical and Analysis Institute on Addictions.

Utilizing quite a lot of analytical strategies, together with machine-learning strategies, they evaluated month-to-month alcohol gross sales knowledge reported by the U.S. Nationwide Institute on Alcohol Abuse and Alcoholism (NIAAA), in addition to anonymized mobility knowledge from over 45 million sensible cellular gadgets (principally smartphones) indicating folks’s visits to companies the place alcohol is offered. (The NIAAA knowledge focuses on month-to-month gross sales of alcohol for 16 U.S. states. It contains gross sales of spirits, wine and beer, however not all states report knowledge in all of these classes.)

The evaluation discovered that general, gross sales of spirits and wine elevated within the early months of the pandemic—by as a lot as 20-40% in some states in sure months—whereas beer gross sales declined general in comparison with the identical interval throughout latest years. In the meantime, folks’s visits to bars and pubs declined, however visits to liquor shops elevated.

Dynamics diverse considerably throughout states. For instance, whereas beer gross sales decreased in most states between March and June 2020 in contrast with the identical months lately, they elevated in Kansas, Arkansas and Texas. In the meantime, Texas, Kentucky and Virginia confirmed sustained will increase of their gross sales of each spirits and wine, which the authors recommend “may be alarming indicators for problematic alcohol use.”

“If knowledge can present details about geographic areas wherein alcohol use will increase throughout sure sorts of occasions reminiscent of throughout extreme climate, excessive unemployment, or occasions such because the COVID pandemic, this info may be helpful to assist put together legislation enforcement, medical professionals and substance use dysfunction remedy suppliers to handle alcohol-related points related to such occasions,” Quigley says.

Machine-learning assessments within the research level to a major shift within the relationship between alcohol gross sales knowledge and visits to varied alcohol shops. Extra analysis will likely be obligatory to grasp how folks’s behaviors modified, however these findings recommend the chance that some states might have seen a rise in on-line alcohol purchases or panic shopping for of spirits and wine.

The analysis workforce notes that the research has some limitations: For instance, many states weren’t included within the NIAAA dataset, and the human mobility knowledge was not in a position to seize alcohol gross sales at locations reminiscent of grocery shops, the place gross sales of alcohol are combined with gross sales of different gadgets. However, these outcomes present insights into the potential results of lockdown insurance policies on alcohol use and will inform future public well being insurance policies to handle alcohol-related social points, the researchers say.

From a analysis methodological perspective, Taylor, Ph.D., UB assistant professor of arithmetic, notes, “Interfacing new knowledge sources reminiscent of anonymized human mobility knowledge with public well being challenges which can be troublesome or costly to instantly measure reveals new methodological challenges for utilized machine studying analysis.”
