Abstract
PURPOSE A growing body of evidence suggests that oral health is associated with a wide range of health outcomes; however, opinions tend to vary because of inconsistent findings. This study aimed to simultaneously examine the association between oral health status and multiple health and well-being indicators using outcome-wide epidemiology. METHODS Data were obtained from the Japan Gerontological Evaluation Study. Oral health status was categorized as: ≥20 teeth, 10-19 teeth with dental prosthesis, 0-9 teeth with prosthesis, 10-19 teeth without prosthesis, and 0-9 teeth without prosthesis. We examined the associations between oral health status in 2013 and 35 health and well-being outcomes in 2019, including physical/cognitive health, psychological distress, subjective health, social well-being, prosocial/altruistic behaviors, and health behaviors, using two databases (n=32,827 and 15,905). RESULTS Compared to individuals with ≥20 teeth, those with <20 teeth had a 10-33% higher risk of mortality and a 6-14% higher risk of functional disability six years later. Additionally, individuals with fewer than 20 teeth tended to go out less frequently and eat fewer vegetables and fruits. Furthermore, individuals with 0-9 teeth without a prosthesis were more likely to have severe functional disability (risk ratio (RR):1.17, 95% confidence interval (CI):1.05-1.31), engage in fewer intellectual activities (standardized difference: 0.17, 95% CI: 0.10-0.24), and feel more hopeless (RR: 1.21, 95% CI: 1.04-1.41). CONCLUSIONS The prevention of tooth loss and prosthodontic treatment may be associated with reduced mortality and functional disability, as well as maintenance of intellectual ability, frequency of going out, and improvements in dietary lifestyle.

Front Public Health 2023; 11:1194054. [PMID: 37342280 PMCID: PMC10277727 DOI: 10.3389/fpubh.2023.1194054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Accepted: 05/17/2023] [Indexed: 06/22/2023] Open
Abstract
Objectives The available evidence on the connections between tooth loss, denture use, and mortality from all causes or specific causes among older adults is inconclusive. Therefore, we aimed to investigate the association between tooth loss, denture use, and all-cause and cause-specific mortality in older adults. Methods A cohort of 5,403 participants aged 65 and older were recruited in the 2014 Chinese Longitudinal Healthy Longevity Survey wave and followed up in the 2018 wave. Cox proportional hazard models were used to examine the association between the number of natural teeth, denture use, and all-cause and cause-specific mortality. Results During a mean (SD) follow-up of 3.1 years (1.3), 2,126 deaths (39.3%) occurred. Individuals with 0 and 1-9 teeth had higher mortality due to all-cause, cardiovascular disease (CVD), cancer, and other causes (all p-trend <0.05) than those with 20+ teeth. At the same time, no association was found with respiratory disease mortality. Participants who used dentures had lower mortality due to all causes [hazard ratios (HR) 0.79, 95% confidence intervals (CI) 0.71-0.88], CVD (HR 0.80, 95% CI 0.64-1.00), respiratory disease (HR 0.66, 95% CI 0.48-0.92), and other causes (HR 0.77, 95% CI 0.68-0.88) than those without dentures. Joint analysis revealed that older adults with fewer natural teeth and no dentures had higher mortality. Additionally, interaction analyses showed that the effects of the number of natural teeth on all-cause mortality were more pronounced in older adults aged <80 years (p-value for interaction = 0.03). Conclusion Having fewer natural teeth, particularly less than 10 teeth, is linked to an increased risk of mortality from all causes, including CVD, cancer, and other causes, but not respiratory disease. The use of dentures would mitigate the adverse impact of tooth loss on all-cause and some cause-specific mortality.

Association between self-reported oral health and cognitive function among the community-dwelling elderly in Jinan, China: the mediating effect of life satisfaction. Front Psychol 2023; 14:1116325. [PMID: 37303887 PMCID: PMC10248475 DOI: 10.3389/fpsyg.2023.1116325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 05/09/2023] [Indexed: 06/13/2023] Open
Abstract
Background Deterioration of self-reported oral health and decline in cognitive function are two main adverse health outcomes experienced by the older adults. Little evidence was found on the psychosocial mechanism between self-reported oral health and cognitive function. This study explores the association between self-reported oral health and cognitive function and examines the mediating effect of life satisfaction among the community-dwelling elderly in Jinan, China. Methods A total of 512 older individuals (60+) were included in the study. Cognitive function was assessed using the Chinese version of the Mini-Mental State Examination scale (MMSE), and self-reported oral health was measured using the Chinese version of the Geriatric Oral Health Assessment Index (GOHAI). Pearson correlation analysis was used to determine the relationship between self-reported oral health, life satisfaction, and cognitive function. Multivariate linear regression analysis was conducted to explore the possible effect of covariates. Structural equation modelling and Bootstrap analyses were conducted to verify the mediating role of life satisfaction. Results The mean MMSE score was 25.65 ± 4.42. Better self-reported oral health was significantly associated with a higher level of life satisfaction, and those with higher life satisfaction experienced better cognitive function. Age, educational level and source of living expenses were found to be cofounding variables. Life satisfaction partially mediated the effect of self-reported oral health on cognitive function (95% confidence interval [CI]: 0.010 to 0.075). The mediating effect of life satisfaction accounted for 24% of the total effect. Conclusion The level of cognitive function was relatively high. Self-reported oral health was positively associated with cognitive function, and the mediating effect of life satisfaction was proven to exist in the community-dwelling older individuals. Early screening for oral diseases and a greater focus on life satisfaction are recommended.

Abstract
AIM Social isolation and oral health problems commonly exist in older populations and can influence each other. However, evidence on this bidirectional correlation is scarce. This systematic review aimed to provide a comprehensive overview of literature in which social isolation and oral health were associated with each other separately. METHODS Electronic searches were performed through six databases. Original cross-sectional and longitudinal prospective studies that evaluated the associations between social isolation and oral health as either exposure or outcome were included. RESULTS In total, 282 articles were retrieved. Of these, 10 cross-sectional studies and one longitudinal study were included in the analysis. The level of evidence reported was generally moderate to strong. Most studies found that both stronger objective and perceived social isolation were associated with worse oral health in both directions. The frequency of meeting friends had an inconsistent association with oral health. CONCLUSIONS The results of our systematic review showed a bidirectional association between social isolation and oral health in independent community-dwelling older adults. Both objective and perceived social isolation are associated with oral health. As objective social isolation indicators, quality of social connectedness appears to play a more important role in the association with oral health.

Abstract
AIM Tooth loss and cognitive decline progress over time and influence each other. This study estimated the impact of sustaining natural dentition on cognitive function in U.S. adults, accounting for the fact that dental and cognitive statuses change over time. MATERIALS AND METHODS Data from adults aged ≥51 years who participated in five waves of the Health and Retirement Study from 2004 to 2016 (n = 10,953) were analysed. The impact of retaining some natural teeth from 2006 to 2012 on cognitive function score (0-27) and cognitive impairment (defined as having a cognitive function score of <12) in 2016 was evaluated using the doubly robust targeted maximum likelihood estimation method by considering both time-invariant and time-varying confounders, including cognitive function at baseline and during follow-up. RESULTS Respondents with some natural teeth between 2006 and 2012 had a 0.40 point (95% confidence interval [CI]: 0.10-0.71) higher cognitive function score and 3.27 percentage point (95% CI: 0.11-6.66) lower cognitive impairment prevalence in 2016 than those with complete tooth loss. CONCLUSIONS Considering past cognitive function assessed at multiple time points, sustained natural dentition was associated with better cognitive function.

Abstract
Background Hearing loss has occurred as a critical concern for aging and health. However, it remains unknown whether nocturnal sleep and midday napping duration are associated with hearing loss in middle-aged and older adults. Methods The study comprised 9,573 adults from China Health and Retirement Longitudinal Study, who have completed the survey for sleep characteristics and subjective functional hearing. We collected self-reported nocturnal sleep duration (<5, 5 to <6, 6 to <7, 7 to <9, ≥9 h/night) and midday napping duration (≤5, 5 to ≤30, and >30 min). The sleep information was classified into different sleep patterns. The primary outcome was self-reported hearing loss events. Multivariate Cox regression models and restricted cubic splines were used to investigate the longitudinal association of sleep characteristics with hearing loss. We applied Cox generalized additive models and bivariate exposure-response surface diagrams to visualize the effects of different sleep patterns on hearing loss. Results We confirmed 1,073 cases of hearing loss (55.1% female) during the follow-up. After adjusting for demographic characteristics, lifestyle factors and health condition, nocturnal sleep with < 5 h was positively associated with hearing loss [hazard ratio (HR): 1.45, 95% confidence interval [CI]: 1.20, 1.75]. Individuals with napping for 5 to ≤30 min had a 20% (HR: 0.80, 95%CI: 0.63, 1.00) lower risk of hearing loss compared with those with napping ≤ 5 min. Restrictive cubic splines showed the reverse J-shaped association between nocturnal sleep and hearing loss. Moreover, we found significant joint effects of sleeping < 7 h/night and midday napping ≤ 5 min (HR: 1.27, 95% CI: 1.06, 1.52) on hearing loss. Bivariate exposure-response surface diagrams also reflected the finding that short sleep without napping existed the highest risk of hearing loss. Compared with persistently sleeping moderately (7-9 h/night), those who persistently slept < 7 h/night or shifted from < 7 h/night to moderate or > 9 h/night had higher risks of hearing loss. Conclusion Inadequate nocturnal sleep was associated with an elevated risk of poor subjective hearing in middle-aged and older adults, while moderate napping decreased the risk of hearing loss. Keeping sleep stable within recommendation duration may be a useful strategy for preventing poor hearing loss.

Abstract
PURPOSE Measuring health-related quality of life (HRQOL) in various health conditions in different countries is important given the regional differences. This study employed large-scale nationwide data targeting older adults in Japan to estimate the HRQOL in the key health conditions that are the major causes of disability. METHODS Our data were derived from two survey waves (2016 and 2019 surveys) of cross-sectional data from the Japan Gerontological Evaluation Study, an ongoing nationwide study targeting functionally independent older adults in Japan. A total of 28,345 individuals from 27 of the 47 Japanese provinces were analyzed. The EuroQoL 5-dimension 5-level instrument (EQ-5D-5L) was employed to assess the HRQOL utility scores. The targeted minimum loss-based estimator with sampling weighting methods was applied to estimate the utility score in eight major health conditions, including sensory organ disease, musculoskeletal disease, oral disorders, and depressive disorders. RESULTS The estimated HRQOL utility score for those with the poorest health conditions in self-rated health, hearing loss, vision loss, number of remaining teeth (e.g., no teeth with no denture use), oral dysfunction, depressive symptoms, chronic low back pain, and chronic knee pain was 0.576 (95% confidence interval (CI) 0.555-0.598), 0.768 (95% CI 0.737-0.800), 0.680 (95% CI 0.662-0.699), 0.809 (95% CI 0.796-0.821), 0.776 (95% CI 0.764-0.788), 0.723 (95% CI 0.710-0.737), 0.715 (95% CI 0.690-0.739), and 0.742 (95% CI 0.722-0.763), respectively. CONCLUSION We successfully provided a catalog for the HRQOL utility score in key health conditions that are the leading causes of disability among older adults.

Abstract
This study investigated the relationship between eye frailty and physical, social, and psychological/cognitive weaknesses among older adults in Japan. The participants were 192 community-dwelling older adult women. We measured handgrip strength, walking speed, and skeletal muscle mass; additionally, their physical, social, and psychological/cognitive frailties were surveyed using questionnaires. Eye frailty self-checks were used to assess eye frailty. Exploratory and confirmatory factor analyses were employed to verify the validity of the eye frailty self-checks. Eye frailty prevalence and related factors were investigated by conducting a binomial logistic regression analysis, with eye frailty as the dependent variable. The factor analysis results showed that a model could be constructed with the two factors of visual acuity or contrast and visual field. The model's goodness of fit was acceptable, supporting the validity of the self-checking construct. The Kihon checklist was the only variable with a significant relationship to eye frailty. Regarding the relationship between eye frailty and subordinate items of the Kihon checklist, social withdrawal [odds ratio (OR) 2.437, 95% confidence interval 1.145-5.188], cognitive function (OR 2.047, 95%CI 1.051-3.984), and depressed mood (OR 1.820, 95%CI 1.163-2.848) were significant. Eye frailty can be considered a factor reflecting the existence of social and psychological/cognitive frailties.

Abstract
PURPOSE Uncorrected refractive error (URE) is the leading cause of vision impairment and the second leading cause of blindness. It is a major public health challenge worldwide. However, the current status of URE in Japan is unclear. STUDY DESIGN Cross-sectional study. METHODS In 2012, a population-based cross-sectional study was conducted among community dwellers aged 40 years and older who received health check-ups in Minamiaizu and Tadami, Fukushima Prefecture, Japan. URE was considered when the presenting visual acuity in the better-seeing eye was < 0.5 and when visual acuity improved more than 1 line with refractive correction in the better-seeing eye. We estimated the age-specific prevalence of URE, and calculated the p-value for trend to examine the linear pattern of the association of the prevalence of URE and age. RESULTS This analysis included 2952 participants. The mean age (standard deviation [SD]) of the study population was 69.10(9.67) years and 57.79% were women. The overall prevalence of URE was 10.90% (95% CI, 9.77-12.05%). Prevalence by age category was 5.00% (95% CI, 2.03-10.03%), 6.09% (95% CI, 3.59-9.58%), 7.02% (95% CI, 5.49-8.81%), 11.96% (95% CI, 10.15-13.97%), and 22.39% (95% CI, 18.41-26.78%) for 40-49 years, 50-59 years, 60-69 years, 70-79 years, and 80 years or older, respectively (p-for trend, < 0.001). CONCLUSIONS The prevalence of URE was 10.9% and exceeded 20%, especially in individuals older than 80 years. Given the correlation between increasing incidence of URE and increase in age, public health intervention to promote awareness of URE is important, especially for the older population.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182212265. [PMID: 34832020 PMCID: PMC8620215 DOI: 10.3390/ijerph182212265] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 11/18/2021] [Accepted: 11/20/2021] [Indexed: 11/16/2022]
Abstract
Reduction of the incidence of depression and improvement of quality of life (QOL) of elderly people have become important subjects. Various factors are related to depressive symptoms in elderly people, and sensory impairment is a key to health, QOL, and depressive symptoms. In this cross-sectional study, a visual acuity test and audiometry were used to examine the relationships of visual and hearing impairment and other factors with depressive symptoms in elderly people. A group of 490 community-dwelling people aged over 65 years old underwent vision and hearing tests, the Center for Epidemiologic Studies Depression Scale (CES-D), Mini-Mental State Examination (MMSE), and questionnaires on social isolation, QOL, and physical condition. Logistic regression analysis was used to examine factors affecting CES-D. Multivariate logistic regression analysis indicated that hearing impairment, pain score, and satisfaction with human relationships and activities of daily living (ADL) were independent predictors of CES-D scores. Satisfaction with human relationships and ADL can reduce depressive symptoms in elderly people. Hearing impairment, pain, and social contact are also important. Therefore, improvement of social networks, interpersonal relationships, ADL, and hearing impairment may be effective in improving these symptoms in elderly people.

Results from the NEIGE Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182111082. [PMID: 34769605 PMCID: PMC8582950 DOI: 10.3390/ijerph182111082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 10/13/2021] [Accepted: 10/19/2021] [Indexed: 12/17/2022]
Abstract
Background: Childhood maltreatment can impede gratitude, yet little is known about the older population and its moderators. The aim of this study is to clarify the association between childhood maltreatment and levels of gratitude of the older population, and the moderating effect of social ties on the association. Methods: We analyzed the data of 524 community-dwelling older adults aged 65–84 years without functional disabilities in Tokamachi City, Niigata, Japan, collected for the Neuron to Environmental Impact across Generations (NEIGE) study in 2017. Using a questionnaire, the participants rated three types of childhood maltreatment before the age of 18 (physical abuse, emotional neglect, and psychological abuse), level of gratitude, and social ties. Results: We found an inverse association between emotional neglect and gratitude. Furthermore, emotional neglect was inversely associated with gratitude only for those with lower levels of social ties. Conclusions: Promoting social ties may mitigate the adverse impact of emotional neglect on the level of gratitude.
