Background Bacteria involved in chronic periodontal disease induce inflammatory cytokines. These cytokines can enter the brain through systemic circulation and cause depression. In this study, we investigated the association between depressed mood and chronic periodontitis in older adults in Korea. Methods This study used data from the Life‐changing Period Health Checkup (2007–2008), performed only at 66 years of age, which is available from the National Health Insurance Service‐Senior Cohort Database. The depressed mood status was evaluated by three questions in the mental health examination. The definition of chronic periodontitis was determined based on the diagnosis and treatment codes for chronic periodontitis. Based on the three questions, we investigated the association between depressive mood and chronic periodontal disease by dividing the study population into 9622 depressed mood subjects (DMS) and 9091 non‐depressed mood subjects (NDMS). Multivariable‐adjusted logistic regression analysis was performed, and odds ratios (ORs) with 95% confidence intervals (95% CIs) were presented. Results Among the NDMS, 5390 patients with chronic periodontitis were identified, and among the DMS, 5964 patients with chronic periodontitis were identified. The crude OR (95% CI) for chronic periodontitis in DMS compared to NDMS was 1.12 (1.06–1.19). The adjusted OR (95% CI) for chronic periodontitis was 1.12 (1.06–1.19). As a result of confirming the effect of sex and comorbidity on the association between depressed mood and chronic periodontitis, a significant association was observed for women at 1.15 (1.07–1.25). In addition, the adjusted OR (95% CI) for depressive mood and chronic periodontitis was 1.15 (1.07–1.25) for patients with hypertension, 1.13 (1.03–1.25) for patients with diabetes, 1.12 (1.02–1.22) for patients with dyslipidemia, and 1.18 (1.04–1.34) for patients with heart disease. Conclusions This study confirmed the relationship between depressed mood and chronic periodontitis in older adults. Therefore, education to strengthen the emotional management of older adults, especially with respect to depression, would play an auxiliary role in preventing and treating periodontitis.
