Objectives The aim of this study was to identify the socioeconomic factors associated with the prevalence of periodontitis in Koreans. Methods Cross‐sectional data from 12 763 subjects, 15 years old and above, who underwent periodontal examinations were obtained from the K orean N ational H ealth and N utrition E xamination S urvey IV (2007–209). Multivariate linear and logistic regression analyses were applied to estimate the association between socioeconomic indicators and prevalence of periodontitis. Results A significant association was found between increasing age and periodontitis. Participants with higher income were less likely to have periodontitis (aOR = 0.9 and 95% CI = 0.78–0.98, and aOR = 0.7 and 95% CI = 0.60–0.80 in the middle and highest quintiles of monthly household income, respectively). In addition, participants living in rural areas were less likely to have periodontitis (aOR = 0.9 and 95% CI = 0.81–0.99), and current smokers were more likely to have periodontitis (aOR = 1.7 and 95% CI = 1.49–1.89). The analysis of comorbidities revealed that individuals with diabetes mellitus ( DM ) were significantly more likely to have periodontitis (aOR = 1.4 and 95% CI = 1.18–1.68). Conclusions In a rapidly increasing K orean population, the lower socioeconomic groups as well as individuals with DM were significantly more likely to present with periodontitis.
