Purpose: The purpose of this study was to analyze the factors associated with self-rated poor oral health and chewing discomfort among Korean elderly people in the Korea National Health and Nutrition Examination Survey(KNHANES). Materials and Methods: Data from the 7th(2016-2018) KNHANES were downloaded from the KNHANES website. Participants were older adults aged 70 years who responded to a questionnaire about their self-rated oral health or chewing discomfort. Multivariate logistic regression analysis was performed by dividing demographic and oral health factors into three models, and odds ratios with 95% confidence intervals were presented. Results: For self-rated poor oral health, up to 1.59 times increase in caries in permanent teeth and up to 1.84 times in crease in severe periodontitis, and up to 2.41 times increase in negative perceptions for those with 20 or more natural teeth compared to those without. In terms of chewing discomfort, depending on the model, those with a middle school diploma or less had up to 2.05 times more discomfort than those with a college degree or higher. Having severe periodontitis was associated with up to 1.68 times more discomfort, and having fewer than 20 natural teeth was associated with up to 2.46 times more discomfort. Conclusion: Some demographic factors and a number of oral health factors were found to be associated with self-rated poor oral health and chewing discomfort in older adults. Further in-depth analyses that reflect additional factors that were not included in the study are necessary.
