Abstract While empirical evidence shows that cognitive function affects oral health and vice versa, there is a lack of empirical evidence to test the reciprocal relationship between these two indicators. This study aimed to examine this relationship among middle-aged and older adults in China. Data were derived from the 2011 and 2015 waves of the China Health and Retirement Longitudinal study. A two-wave cross-lag analysis was adopted to test the hypothesized model. Cognitive function in 2011 was found to be a significant predictor of complete tooth loss in 2015. Furthermore, complete tooth loss in 2011 was found to be a significant predictor of cognitive cognition in 2015. This finding demonstrates the reciprocal relationship between cognitive function and oral health. This study highlights the importance of improving both cognitive health and oral health for middle-aged and older adults. Policy and intervention implications are discussed.

Abstract Objective Previous longitudinal studies have found that cognitive function affected oral health, and vice versa. However, research is lacking on the reciprocal relationships between cognitive function and edentulism simultaneously, especially in developing countries. The present study aimed to examine the reciprocal relationship between cognitive function and edentulism among middle-aged and older adults in China. Methods Data were derived from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study. The sample included 14,038 respondents aged 45 or older. A two-wave cross-lagged analysis was adopted to test the hypothesized model. Results Among respondents aged 45–59, baseline cognitive function was associated with subsequent edentulism [b = −0.017, standard deviation (SD) = 0.006, P < 0.01]. In contrast, baseline edentulism was not significantly associated with poorer cognitive function at the follow-up wave (b = −0.744, SD = 0.383, P > 0.05). However, among respondents aged 60 or older, baseline cognitive function was associated with subsequent edentulism (b = −0.017, SD = 0.005, P < 0.01), and baseline edentulism was also associated with follow-up lower levels of cognitive function (b = −0.419, SD = 0.143, P < 0.01). Conclusions These findings demonstrated the reciprocal relationships of cognitive function and edentulism. However, such relationships varied across age groups. This study demonstrates the importance of developing programs and services to promote both cognitive and oral health, especially for those in older age.

Abstract There is an increasing awareness of the importance of oral health and its associated risk factors among older adults. This symposium includes four papers that address cognitive function, social support and oral health problems and symptoms among older adults in the U.S. and China. Lu and his colleagues examined the reciprocal relationship between cognitive function and complete tooth loss Chinese adults age 50+ using the China Health and Retirement Longitudinal study. The results show that there is a reciprocal relationship between these two indicators. The second paper used the Population Study of Chinese Elderly in Chicago (PINE) and examined the associations between tooth/gums symptoms and changes in cognitive function in Chinese older immigrants. The results reveal that having teeth symptoms was associated with a decline in cognitive function. Using the same PINE data, the third paper examined the association between different characteristics of social relationships and the number of oral health problems among U.S. older Chinese adults. Wu and her colleagues conducted a partner-assisted pilot intervention to improve oral health for community-dwelling older adults with either mild cognitive impairment or mild dementia. The results of this 6-month intervention show that persons in the treatment group had more improvement in oral hygiene than those in the control group. Findings from these four papers illustrate that cognitive function, social support, and oral health are interrelated. This symposium highlights the importance of improving cognitive health, social support, and oral health for middle-aged and older adults.

BACKGROUND Till date no longitudinal prospective study have investigated the association between the oral health status and cognitive decline in the geriatric Indian population, possibly due to past studies differing in target groups and methodologies. We aimed to investigate the association between tooth loss, as evaluated through clinical oral examinations, and the development of cognitive decline in the older adults while considering baseline cognitive function. OBJECTIVE to investigate the association between tooth loss, as evaluated through clinical oral examinations, and the development of cognitive decline in the older adults while considering baseline cognitive function. METHODS This 5-year prospective cohort study followed 140 participants (mean age: 72.5 ± 4.3 years) without cognitive impairment aged ≥65 years (mean age: 70.9 ± 4.3 years) living in the Dhule Region of Maharashtra , India. Cognitive function was evaluated with the Mini-Mental State Examination (MMSE) in baseline and follow-up surveys,while oral health examination was carried out using Oral Hygiene Index To investigate the association between oral health status and cognitive decline, we applied a multiple logistic regression analysis adjusted for age, gender, hypertension, diabetes, cerebrovascular/cardiovascular disease, hypercholesterolemia, depressive symptoms, body mass index, smoking status, drinking status, duration of education, and baseline MMSE score. RESULTS In the 5 years after the baseline survey, we have obtained an overall incidence of 20.71%. population who developed cognitive decline (i.e., MMSE scores of ≤24). Multivariable logistic regression analysis indicated that participants with compromised oral health were more likely to develop cognitive decline than those with mild to moderate oral health were (odds ratio: 3.31; 95% confidence interval: 1.07–10.2). Age, male gender, and baseline MMSE scores were also significantly associated with cognitive decline. CONCLUSIONS Poor Oral health status was independently associated with the development of cognitive decline within 5 years among the geriatric population of India . This finding corroborates the hypothesis that oral health may be a predictor or risk factor for cognitive decline. CLINICALTRIAL Not applied

Bidirectional Relations

Abstract Background evidence suggests a reciprocal relationship between cognitive function (CF) and oral health (OH), but no study has demonstrated this inter-relationship in a longitudinal population. Objective to investigate the bidirectional relationship between CF and OH in an ageing cohort. Design cohort study. Setting general community. Subjects participants from the English Longitudinal Study of Ageing. Methods OH, measured by teeth status, self-reported OH and OH-related quality of life (OHRQoL), and CFs were collected at three time points in 2006/07, 2010/11 and 2014/15. Cross-lagged structural equation models were used to investigate the association between CF and OH, adjusted for potential confounding factors. Results 5477 individuals (56.4% women) were included (mean age = 63.1 years at 2006/07, 67.2 at 2010/11 and 70.4 at 2014/15, SD = 8.9) in analyses. The average CF score was 46.5(SD = 12.3) at baseline and 41.2 (SD = 13.4) at follow-up. 3350 (61.2%) participants had natural teeth only and 622 (11.2%) were edentulous. In the fully adjusted model, better cognition at baseline was associated with better OH at follow-up (beta coefficient = 0.02, 95% CI: 0.01–0.03); conversely better OH at baseline predicted better cognition (beta coefficient = 0.12, 95% CI: 0.06–0.18). Similar magnitude and direction of the reciprocal association was evident between cognition and OHRQoL. Conclusions This is the first longitudinal study to demonstrate the positive reciprocal association between CF and OH. The findings suggest the importance of maintaining both good CF and OH in old age.

AbstractRecent findings suggest that social disengagement in later life may result in cognitive decline and increase risk of Alzheimer’s and related dementias. However, little is known regarding the gender-specific longitudinal association between social engagement and cognition among middle-aged and older adults. Using data from a nationally representative sample of 2707 men and 5196 women from the Korean longitudinal study of aging, we examined the gender-specific association between social activity and cognitive function. Results from the generalized estimating equation model showed that compared to individuals with consistent social engagement (religious, senior center, sport, reunion, voluntary, political), individuals with inconsistent engagement had lower cognitive function. Transitioning from engagement to non-engagement was associated with lower cognitive function among men only. Not being part of a senior center was associated with decreased cognitive function among both genders, while not being part of a religious group was significant for women only. While marital status was a significant predictor of cognitive ability for women, depression was a significant predictor for men. These findings have implications for policy-makers as interventions targeting improved cognitive function among middle-aged and older adults may be more effective when gender-specific predictors are taken into consideration.

Abstract Background Associations between the frequency of social and intellectual activities and cognitive trajectories are understudied in Chinese middle-aged and older adults. We aimed to examine this association in a nationally representative longitudinal study. Methods The China Health and Retirement Longitudinal Study (CHARLS) is a nationally representative sample of Chinese middle-aged and older participants. The frequency of social and intellectual activities was measured at baseline. Interview-based cognitive assessments of orientation and attention, episodic memory, and visuospatial skills and the calculation of combined global scores were assessed every 2 years from 2011 to 2016. Cognitive aging trajectories over time were analyzed using group-based trajectory modeling, and the associations of the trajectory memberships with social and intellectual activities were analyzed using multinomial logistic regression. Odds ratios (OR) and 95% confidence intervals (CI) were reported. Results Among 8204 participants aged 50–75 years at baseline, trajectory analysis identified three longitudinal patterns of cognitive function based on the global cognitive scores: “persistently low trajectory” (n = 1550, 18.9%), “persistently moderate trajectory” (n = 3194, 38.9%), and “persistently high trajectory” (n = 3460, 42.2%). After adjustment for sociodemographic variables, lifestyles, geriatric symptoms, and health conditions, more frequent intellectual activities (OR 0.54, 95% CI 0.38–0.77) and social activities (OR 0.79, 95% CI 0.65–0.95) were both associated with a lower likelihood of being in the “persistently low trajectory” for global cognitive function. Conclusions These findings suggested that more frequent social and intellectual activities were associated with more favorable cognitive aging trajectories.

Abstract This study examined the joint effects of diabetes and poor oral health on cognitive function among older adults aged 60 years or older in the U.S. We analyzed data of 2,937 participants from the National Health and Nutrition Examination Survey (2011-2014). We investigated the interaction effects between diabetes and significant tooth loss, i.e. differences among the following four groups: 1=neither of the two conditions, 2=non-diabetic but with tooth loss, 3=diabetic but no tooth loss, and 4=both conditions. Significant interaction effects were found in our study. Having either diabetes or significant tooth loss was associated with lower cognitive function. When the two conditions were both present, the negative effects were much stronger than the total effects from either one of the two conditions. The additional loss of cognitive function resulting from multiple health conditions illustrates the importance of improving access to dental care for older adults in the U.S.
