“…Data from a longitudinal study, collected as part of the Japan Gerontological Evaluation Study (JAGES) project, an ongoing Japanese prospective cohort study [ 15 , 16 ], were used for the present study. The JAGES aims to investigate factors associated with the loss of healthy years, such as functional decline, cognitive impairment, and death among non-institutionalized older people.…”

We sought to examine if self-reported oral health conditions regarding difficulty eating tough foods, dry mouth, choking, number of teeth and denture use are associated with incident falls. Our study was based on panel data from the Japan Gerontological Evaluation Study conducted in 2010 and 2013 using self-administered questionnaires. Data from 19,995 male and 20,858 female community-dwelling older people aged ≥65 years without a history of falls within the previous year in 2010 were analyzed. Multilevel logistic regression models were used to determine the association between poor oral health in 2010 and multiple incident falls in 2013 after adjusting for possible confounders and considering differences in municipalities. The percentage of males and females who reported falls in 2013 were 2.4% and 2.1%, respectively. After adjusting for age, educational attainment, equivalized income, depression, self-rated health, instrumental activities of daily living, body mass index, present illness related to falls, social participation, walking in min/day, alcohol drinking status, and municipality population density, dry mouth in males (odds ratio [OR] = 1.41; 95% confidence interval [CI]: 1.12–1.77) and choking in females (OR = 1.64; 95% CI: 1.27–2.11) were significantly associated with incident falls. Difficulty eating tough foods in both sexes and choking in males were marginally associated with incident falls (p<0.1). Females having 10–19 teeth without dentures (OR = 1.63; 95% CI: 1.14–2.31), ≤9 teeth with dentures (OR = 1.36; 95% CI: 1.03–1.80), and ≤9 without dentures (OR = 1.46; 95% CI: 1.02–2.08) were significantly associated with incident falls compared with those having ≥20 teeth, respectively. These findings suggest that poor oral function, having fewer teeth, and not using dentures are predictors of incident falls. Further studies are needed to determine whether improving oral health can reduce the risk of falls.

“…The first hypothesis is that psychiatric disorders trigger an over active inflammatory response to stressors and pathogens (Warren et al., ), for example in the periodontal tissues. Poor oral health has been reported as a risk factor for depression (Hsu et al., ; Yamamoto et al., ). Some researchers have already reported certain mediators which have strong associations between these diseases (Mousavijazi, Naderan, Ebrahimpoor, & Sadeghipoor, ).…”

Aim This study aimed to investigate the factors associated with periodontal traits considering genetic and environmental background in predominantly older female twins. Methods This was a cross‐sectional study using self‐reported questionnaires for periodontal traits in TwinsUK. Age‐adjusted and age‐stratified multivariate analyses were conducted for all twins. Subsequently, co‐twin control analysis within genetically identical twins who were discordant for periodontal traits was performed by controlling for genetic confounders. Results Data of twins aged 20–91 were available in 4,143 individuals for self‐reported periodontitis and 4,244 for gum bleeding. Age‐adjusted model showed increasing risk in the following: smoking, anxiety/stress and depression for both periodontal traits. Within discordant monozygotic (MZ) twins (514 individuals for periodontitis and 754 for gum bleeding), the association of anxiety/stress remained significant for both periodontitis (OR 1.60, CI: 1.02–2.52) and gum bleeding (OR 1.60, CI: 1.06–2.40). A significant relationship for depression remained for periodontitis (OR 1.68, CI: 1.04–2.70), but it was no longer significant for gum bleeding. Age stratification showed that the association of mood disorders with periodontal traits was generally stronger in older group. Conclusions Multivariate analysis among discordant MZ female twins found mood disorders were independently associated with periodontal traits, suggesting that genetic/early‐life environmental factors may not explain this association.

“…5,6 Difficulty in chewing hard foods and the lack of natural teeth are also associated with depressive symptoms in older Japanese. 7 However, the relationships between ageing, depression and oral health remain understudied and unclear. In a world with an ageing population, a better understanding of these relationships is important, particularly if simple oral health interventions reduce the risk of accumulating depressive symptoms.…”

Associations between oral health and depressive symptoms: Findings from the Concord Health and Ageing in Men Project

Objective: To investigate whether poorer oral health, tooth loss and lower usage of dental services are associated with depressive symptoms in older Australian men. Methods: Cross-sectional study of data collected from participants of the Concord Health and Ageing in Men Project. Depressive symptoms were evaluated by the Geriatric Depression Scale. Chewing capacity was estimated by ability to chew 11 food items. Results: The prevalence of depressive symptoms was 17.5%. Self-evaluated oral health, chewing capacity and the number of natural and decayed teeth were associated with depressive symptoms. After adjusting for multiple confounders, chewing capacity (PR 1.93; 95% CI 1.34-2.79) and decayed teeth (PR 1.68; 95% CI 1.03-2.75) maintained a significant association with depressive symptoms. Conclusion: The direction of causality between oral health and depression is unclear; however, oral health may contribute to depression in older Australian men and depressive symptoms may limit chewing capacity and be aggravated by untreated dental decay.

Abstract: These findings suggest that having no teeth and oral health problems may play a role in the development or worsening of depressive symptoms.
