Association between health information literacy and oral health-related indicators in Korean adults: a cross-sectional study using data from the 2023 National Health and Nutrition Examination Survey

Objectives: In the present study, we aimed to determine the relationship between health literacy and oral health-related indicators in Korean adults. Methods: We used data from 2023, the second year of the 9th period when health information literacy was newly introduced during the National Health and Nutrition Survey, and grouped it using measurement tools of health information literacy. Results: In model 2, which was corrected for sociodemographic characteristics, the number of units required for a fixed prosthesis increased by 0.098 and difficulties with speaking function increased by 0.138 (p<0.05) in the incorrect answer group compared with that of the correct answer group. Conclusions: The ability to understand health information correlated with oral health-related indicators. Therefore, future policies and educational interventions should focus on simultaneously improving health information comprehension and oral health.
