Solitary and Social Drinking in South Korea: An Exploratory Study

ABSTRACT

Objectives@#This study aimed to identify differences in drinking norms, heavy drinking, and motives between types of drinkers (abstainers, solitary, and social drinkers) in a representative sample of Korean adults. @*Methods@#An online survey of people registered on the electoral roll were randomly invited to be part of the “National Korean Drinking Culture Study” conducted in 2018 (n = 3,015). Participants included 1,532 men and 1,469 women aged 19-60 years. Questions included the number of times they drank in the last month, what they drank, and the volume drank. The amount of pure alcohol consumed was calculated.Drinking norms, motives, and types were determined in the survey questions. @*Results@#Solitary drinkers were more likely to be divorced or separated, less educated, and marginally employed. Solitary drinking peaked in those in their 30s (18.5%) and social drinkers in their 50s (68.1%).Solitary drinkers drank more frequently compared with social drinkers (6.1 vs. 3.6 times per month, p < 0.001), and consumed a significantly larger quantity of alcohol (69.5 g vs. 46.8 g per week). Solitary drinkers were more accepting of drinking-related behaviors in diverse situations compared with social drinkers. The regression analysis revealed that personal drinking motives were the most important factor influencing the frequency and quantity of alcohol consumption in both solitary and social drinking. @*Conclusion@#Solitary drinkers may be more vulnerable to alcohol abuse than social drinkers.
