Abstract
OBJECTIVES
To estimate the prevalence of edentulism according to the socio-demographic variables of Korean adults between 2007 and 2018 and to analyze the trends.
METHODS
This study was conducted using raw data from the Korea National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2018. Edentulism was defined as the absence of upper and lower teeth or the retained root of the missing teeth. To obtain the prevalence of edentulism, complex sample frequency analysis and regression analysis were performed according to the socio-demographic variables to represent the national population. The Korean population structure in 2005 was exploited as a standard population to calculate age-standardized edentulism.
RESULTS
The prevalence of edentulism in 2016-2018 was 9.7% in the Korean elderly, and the change of age-standardized edentulism steadily declined over time from 2007, 12.8%. In particular, it decreased by approximately 20% in the period between 2016 and 2018 compared to that in 2007 for those in their 80s. The trend of the prevalence according to gender decreased significantly in women. According to the level of education, the greatest decrease was seen in the group with the lowest education, although the prevalence itself was higher than that seen in those who were more educated.
CONCLUSIONS
The prevalence of edentulism among the older Korean population has decreased over time. However, the concern is on those with lower education and men as these groups are still at higher risk for edentulism.
Summary
Korean summary
치아상실은 구강건강의 지표로써 현재 국외에서는 무치악 유병률 추이 파악뿐만 아니라 다국 간의 비교가 이루어지고 있지만 아시아의 주요국가 중 하나인 한국의 무치악 유병률 추이에 대해서는 아직 연구되지 않았다. 연구 결과, 2016-2018년 한국 노인의 무치악 유병률은 9.72%였으며, 연령표준화된 무치악 유병률의 변화는 2007 년 12.8 %에서 꾸준히 감소했다. 결론적으로 무치악으로 어려움을 겪을 수 있는 교육수준이 낮은 노인과 남성에 대해선 지속적인 관심이 필요하다.
Key Message
Tooth loss is an indicator of oral health. At present, not only the trend of edentulous prevalence is being identified abroad, but also multi-country comparisons are being made, but the trend of edentulous prevalence in Korea, one of the major Asian countries, has not been studied. As a result of the study, the prevalence of edentulous in Korea in 2016-2018 was 9.72%, and the change in the age-standardized edentulous prevalence steadily decreased from 12.8% in 2007. In conclusion, continuous attention is needed for the elderly and men with low educational standards who may suffer from edentulous.
