Association Between COVID-19-Related Characteristics and Oral Health Status Among Korean Adults

Abstract

This study investigated the association between COVID-19-related characteristics and oral health in Korean adults. Data from the 2021 Korean Community Health Survey were used (n = 229 242). A total of 26.5% responded that their subjective oral health status was good, and 20.2% experienced chewing discomfort. People less affected by COVID-19 in their daily lives were more likely to have good subjective oral health. Subjective oral health status was more likely to be good in those who had increased physical activity, did not consume instant food, smoked less, and were vaccinated against COVID-19. Those who were concerned about being infected, concerned about being criticized, and worried about economic damage due to COVID-19 were more likely to experience chewing discomfort. People with decreased physical activity, increased instant food consumption, and increased alcohol drinking and smoking due to COVID-19 were more likely to experience chewing discomfort. Our findings suggested that COVID-19-related characteristics were associated with oral health status.
