Objectives: To explore changes in self-reported oral health in middle-aged Koreans over a period of 9 years.Methods: This study design was a cross-sectional analysis. This study analyzed the data of 18,845 middle-aged (45-64 years) subjects who participated in 4-6th Korea National Health and Nutrition Examination Surveys (KNHANES). A complex-sample chi-square test was used to analyze self-reported poor oral health according to sex, household income, and education. A complex-sample logistic regression analysis was used to identify the changes in the factors. SPSS 23.0 and the R ver. 3.5.1 statistical package were used for the analyses.Results: Poor oral health have been decreased by 5.3% over the 9-year period. Middle-aged men were more likely to report their oral health as worse than women. The lower income and education groups reported their oral health as poor compared to the higher income and education groups. The factors affecting self-reported poor oral health over the 9-year period were sex, income, and education.Conclusions: More than half of the aged population reported their oral health as poor. Oral health policies should be established for the aged population, including the middle-aged population, for long-term plans.
