The Impact of (COVID)-19 on Beverage Purchasing Behaviors in Korea

Abstract

Objective: In this study, we examined changes in purchase behavior of alcoholic beverages (ie, soju, beer, wine, traditional Korean liquor, and liquor) and non-alcoholic beverages (ie, fruit and vegetable juices, coffee, tea, bottled water, milk, yogurt, and plant-based milk) before and after the COVID-19 pandemic. Methods: Monthly beverage expenditure data, based on Korean household demographic information, was used for 3 years and 6 months. The 2-part model was used for analysis. To examine the effect of COVID-19, beverage expenditure was analyzed after dividing it into short-term and long-term effects. Results: Our results show that the probability of purchasing alcoholic beverages increased owing to the long-term effect of the COVID-19 pandemic. The amounts of beer, wine, and traditional Korean liquor purchased increased in the long-term. The purchase of sweet drinks decreased (ie, fruit and vegetable juices and yogurt) in the long-term because of the effect of the pandemic. On the other hand, tea, water, and plant-based milk expenditures increased. Conclusion: This beverage consumption pattern reflects both unhealthy (ie, an increase in alcoholic beverage purchases) and healthy drinking behaviors (ie, a decrease in sweet beverage purchases and an increase in tea, water, and plant-based milk purchases).
