Abstract

Objectives. This study was designed to examine the effects of socioeconomic status and oral health behaviors on periodontal diseases in the elderly Korean population, to determine whether any inequalities in oral health status exist depending on socioeconomic status, and ultimately to provide essential data for national healthcare policies intended to effectively reduce the inequalities. Methods. The raw data collected from 'The Fourth Korean National Health and Nutrition Examination Survey (KNHANES) 2007' was analyzed in this study. The subjects included in this study were seven hundred and seventy eight (778) elderly people, aged 65 years or older and who had completed the oral examination, health questionnaires and nutrition examination. Results. First, analyses of differences in the prevalence of periodontal diseases depending on socioeconomic status showed that the prevalence of periodontal diseases increases with age and also the prevalence of periodontal diseases is relatively higher in the residents of rural communities such as Eup or Myeon. Second, analyses of differences in the prevalence of periodontal diseases depending on oral health behaviors indicated that a lower frequency of eating between meals leads to a higher prevalence of periodontal diseases. Finally, regarding the magnitude of effects of socioeconomic status and oral health behaviors on periodontal diseases, it was found that both these factors (i.e., socioeconomic status and oral health behaviors) have significant effects on periodontal diseases. However, specifically socioeconomic status has more significant effects on periodontal diseases. Conclusions. In conclusion, it was revealed that considerable inequalities exist in the prevalence of periodontal diseases depending on socioeconomic status in the elderly population, and both the factors of socioeconomic status and oral health behaviors correlate with the prevalence of periodontal diseases. Specifically, the results of this study suggest that the effects of socioeconomic status on periodontal diseases are more significant than the effects of oral health behaviors, and oral health behaviors by themselves closely correlate with socioeconomic status.
