Objectives : This study aimed to identify the factors that affect the utilization of Korean Medicine within the past year. Methods : I analyzed micro-data from the Korean Medicine Utilization Survey (2020), which surveyed the general public. "User (in last 1 year)" were defined as those who had used Korean Medicine within the past year, while "Non-user (in last 1 year)" were defined as those who had used it in their lifetime but not within the past year. I examined several factors, including general characteristics, perceptions of Korean Medicine, satisfaction with Korean Medicine, and intention for future utilization. I conducted the Rao-Scott chi-squared test and complex sample logistic regression analysis. Results : I analyzed a total of 3,762 respondents, of which 1,442 (36.3%) were User (in last 1 year) and 2,320 (63.7%) were Non-user (in last 1 year). User (in last 1 year) and Non-user (in last 1 year) differed significantly in terms of demographic characteristics, perceptions, and satisfaction with Korean Medicine. Women, the elderly, those with low education levels, non-married individuals, those with low-income, chronic diseases, and poor subjective health conditions were significant factors. Those who used Korean Medicine within the past year were more knowledgeable about Korean Medicine than those who had not used it recently, and recognized herbal medicine as safer. In terms of satisfaction, User (in last 1 year) were more satisfied than Non-user (in last 1 year). The more women, the older, the more aware of Korean Medicine, the safer they perceived herbal medicine, the more satisfied they were with its use, the better their subjective health condition, and the absence of chronic diseases, the less they experienced Korean Medicine. Conclusions : The study showed that positive experiences and perceptions of Korean Medicine increase the likelihood of its utilization. Individuals with better subjective health conditions and without chronic diseases have a lower possibility of using Korean Medicine.
