“…This pathway of eating difficulties was highlighted by a recent study, where the reported association between tooth loss and incident ADL disability was explained (10%) by self‐reported eating difficulties in an older population 19 . Furthermore, only in the BRHS, tooth loss was associated with greater incidence of ADL difficulties, in accordance with previous studies 18,19,40 …”

“…One potential direction is that poor oral health, specifically tooth loss, can influence the development of disability, including activities of daily living (ADL), instrumental activities of daily living (IADL), and mobility limitations, in older age. [16][17][18][19][20][21] Nevertheless, limited evidence exists for the associations between oral health and incidence of mobility limitations, defined by difficulty walking and going up stairs, which is a key feature of functional independence. 22 Little is also known about the association of periodontal disease and self-reported oral health measures with incident disability in older adults.…”

Background Preventing oral health problems can be crucial for maintaining physical independence in older adults. We aimed to examine the associations of a range of oral health problems with incidence of disability in older adults. Methods We used prospective data from the British Regional Health Study (BRHS) (N = 2147, 71–92 years), and the Health, Aging and Body Composition (HABC) study (USA) (N = 3075, 71–80 years). Oral health measures included tooth loss, periodontal disease, self‐rated oral health, and self‐reported dry mouth. Participants were followed for onset of disability over a follow‐up period of 3 years. Onset of disability was assessed through new cases of mobility limitations, activities of daily living (ADL), and instrumental activities of daily living (IADL). Logistic regression was performed to calculate the odds of incident disability. Results In the BRHS, tooth loss was associated with greater odds of mobility limitations and ADL difficulties. Periodontal disease was associated with greater incidence of mobility limitations. Self‐report of ≥3 dry mouth symptoms was associated with increased odds of incident mobility limitations and ADL difficulties (OR = 2.08, 95% CI 1.27–3.42; OR = 1.73, 95% CI 1.03–2.90). Fair/poor self‐rated oral health was associated with greater incidence of IADL difficulties. In the HABC study, complete tooth loss was associated with greater incidence of mobility limitations (OR = 1.86, 95% CI 1.13–3.06), and fair/poor self‐rated oral health was associated with increased odds of incident ADL difficulties (OR = 1.42, 95% CI 1.04–1.94). Conclusions Oral health problems in older adults, particularly tooth loss, self‐reported dry mouth and self‐rated oral health were associated with greater incidence of disability. Poor oral health plays a potentially important role in the development of disability in older populations, which in turn is an essential part of quality of life and healthy aging.

“…Previous studies also demonstrated that teeth loss is associated with development of cognitive impairment among older adults [ 18 ]. Teeth loss also increased the risk of functional disability in the elderly population [ 19 ]. Malnutrition, cognitive impairment, and functional disability may lead to nasogastric feeding dependency.…”

Background To examine the association between teeth loss and nasogastric tube feeding dependency in older people. Methods The National Health Interview Survey (NHIS) 2005, 2009, and 2013 in Taiwan. Participants were selected by a multistage stratified sampling method and baseline characteristics, including socioeconomic status and health habits, were obtained by well-trained interviewers. The NHIS was linked with the National Health Insurance research database 2000–2016 and the National Deaths Dataset, which contains all the medical information of ambulatory and inpatient care. Cox regression was used to examine the association between the number of teeth lost and nasogastric tube feeding dependency. Results There were 6165 adults older than 65 years old enrolled in the analysis, with 2959 male (48%) and the mean (SD) age was 73.95(6.46) years old. The mean follow-up duration was 6.5(3.3) years. Regarding the teeth loss categories, 1660 (26.93%), 2123 (34.44%), and 2382 (38.64%) of participants were categorized as having no teeth loss, loss of 1–9 teeth, and loss of 10–28 teeth, respectively. During 39,962 person-years of follow-up, new-onset nasogastric feeding dependency was recognized in 220(13.25%), 256(12.06%), and 461(19.35%) participants who were categorized as having no teeth loss, loss of 1–9 teeth, and loss of 10–28 teeth, respectively. Kaplan-Meier curves demonstrated significant findings (Log-rank P < 0.01). After potential confounders were adjusted, compared with those without teeth loss, older adults who had lost 10–28 teeth had significantly increased risks of occurrence nasogastric feeding dependency (AHR, 1.31; 95% CI, 1.05–1.62; p-value = 0.02). Furthermore, a significant dose-response relation between the number of teeth lost and increased risk of nasogastric feeding was found (p for trend< 0.01). Conclusions Older adults who had lost 10–28 teeth had a significantly increased risk of nasogastric tube feeding dependency. Early identification of the oral disease is crucial for the prevention of the occurrence of teeth loss and the following nutrition problems, which would reduce risk of nasogastric tube feeding dependency.

AimThe effect of dentition status on higher‐level functional capacity patterns over time remains unclear. We aimed to identify distinct higher‐level functional capacity trajectories in individuals aged 70–80 years, and examine whether dentition status at 70 years predicted the trajectory.MethodsThe study included 551 community‐dwelling adults aged 70 years at baseline. Higher‐level functional capacity was measured using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG‐IC) up to the age of 80 years. A higher TMIG‐IC score indicated a higher level of competence. Group‐based trajectory modeling was used to identify distinct TMIG‐IC trajectories. The number of teeth, use of dentures, sex and education were added as baseline group membership predictors. Dental visits, health behaviors, body mass index and comorbidities during observation were added as time‐varying covariates.ResultsThree TMIG‐IC trajectories were identified: “high/stable” (65.3%), “middle/decline” (24.5%) and “low/decline” (10.2%). A lower number of teeth and non‐denture use were associated with increased odds of a low/decline trajectory relative to a high/stable trajectory (odds ratio 1.09, 95% confidence interval 1.04–1.14 [per one decrease] and odds ratio 3.96, 95% confidence interval 1.54–10.16, respectively).ConclusionsOlder adults with fewer teeth and those without dentures at the age of 70 years were more likely to follow a trajectory toward functional decline with low baseline TMIG‐IC scores, which further declines by the age of 80 years. These findings suggest that preserving natural teeth later in life, as well as using dentures, could contribute toward maintaining a higher‐level functional competence.
