Objective: The purpose of this study was to examine the relationship between potential explanatory variables of alcohol harm paradox and the economic class. Methods: This research involved 4,029 adults aged between 19 and 65 years who had drinking experiences over the last year. The sample was drawn form the 15th Korean welfare panel data set published in 2021. Four explanatory variables of alcohol harm paradox including smoking, binge drinking, poor diet, and low accessibility to medical services were selected from the results of literature reviews. Generalized ordered logit analysis was conducted to investigate the relationship between the four variables and the economic class. Results: Among those four variables specified in the research models, smoking and poor diet were found to be statistically significant. The results showed that those who smoked or had poor diet were more likely to belonged to the economically lower class group. Conclusion: This study focused on individual factors of alcohol harm paradox, and found smoking and poor diet were related to the economically disadvantaged. The future studies are needed to examine the explanatory variable beyond the individual level such as community environments or alcohol related polices.
