Relationships between oral function, dietary intake and nutritional status in older adults aged 75 years and above: a cross-sectional study. BMC Public Health 2024; 24:1465. [PMID: 38822295 PMCID: PMC11143706 DOI: 10.1186/s12889-024-18906-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 05/21/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND Malnutrition is related to impaired oral health and function that causes poor dietary intake, declining the general health of older adults. The role of dietary intake in the association between oral function and nutritional status of Chinese older adults (aged 75 and above) was examined in this cross-sectional study. METHODS Through the randomized cluster sampling method, 267 older adults living in rural areas of Qingdao, Shandong (aged 81.4 ± 4.3, 75-94 years) were chosen as the primary research participants. A Mini Nutritional Assessment - Short Form was used to determine nutritional status, and Food Frequency Questionnaire and 24-hour Food Intake Recall were used to assess dietary intake. The oral function was evaluated by analyzing the teeth, oral problems, bite force, tongue pressure, lip sealing pressure, chewing function questionnaire, whole saliva flow rate, 10-Item Eating Assessment Tool, and water swallow test. RESULTS Based on the MNA-SF score, it was divided into a well-nourished group and a malnutrition group, with the malnutrition group comprising 40.6% of participants. The participants in the malnutrition group showed a higher rate of xerostomia, lower bite force, tongue pressure, and lip sealing pressure, and higher Chewing Function Questionnaire and 10-Item Eating Assessment Tool scores. Furthermore, their plant fat, iron, cereals and potatoes, vegetables, fruits, and seafood intake were relatively low. The regression model indicated that exercise frequency, stroke, chewing and swallowing function, intake of vegetables and fruits were risk factors for nutritional status of older adults. CONCLUSION Malnutrition was relatively common among the Chinese older adults aged 75 and above, and it was significantly correlated with exercise frequency, stroke, chewing and swallowing function, and intake of vegetables and fruits. Therefore, nutrition management should be carried out under the understanding and guidance of the oral function and dietary intake of the older adults.

Abstract
BACKGROUND Oral frailty has become a worldwide problem among older adults. Although researchers have conducted various studies on oral frailty, its definition remains controversial. PURPOSE To clarify the concept of oral frailty. METHODS Online databases PubMed, Web of Science, CINAHL, Cochrane Library, ProQuest, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang database were searched from inception to September 20, 2023. The reference lists of relevant studies were searched manually. Eligible articles, theses, and books were analyzed using Walker & Avant's concept analysis model. RESULTS The attributes of oral frailty were abnormal oral structure and/or decline in multi-faceted oral function and coexisting decline in physical, cognitive and social functions. Its antecedents were aging, social frailty, and severe periodontitis, whereas its consequences were decline in physical health and mental health, social withdrawal, lower quality of life and systemic frailty. CONCLUSION Oral frailty could result in worse conditions among older adults physically, psychologically and socially. Tools based on the concept analysis need to be developed to comprehensively assess oral frailty.

Cureus 2024; 16:e56849. [PMID: 38659520 PMCID: PMC11042667 DOI: 10.7759/cureus.56849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 03/24/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Facial muscles, particularly those involved in mastication, play a pivotal role in the chewing process. Despite their influence on chewing, these muscles undergo alterations during mastication. Examining the relationship between chewed substances and muscle activity can provide insights into various pathological processes and aid in the development of therapeutic chewing techniques. AIM This study aimed to evaluate the impact of different commercially available chewing gums on the activity of key masticatory muscles. METHOD Twenty-two participants were recruited for the study. They were instructed to chew four commercially available gums: group 1 comprised sugar gum with a strong flavor; group 2 included gum containing sorbitol; group 3 consisted of gum containing xylitol; and group 4 provided sugar gum with a mild flavor. Electromyogram (EMG) recordings were utilized to assess muscle activity. Various aspects of muscle activity, including chewing time, maximum muscle potential, and coordination between different muscles, were evaluated. Data tabulation and analysis were performed using IBM SPSS software version 23.0 (IBM Corp., Armonk, NY). RESULT Analysis revealed that in terms of temporalis symmetry, group 2 exhibited the highest mean deviation, while for masseter symmetry, group 3 demonstrated the highest mean deviation. The total deviation for the temporalis and masseter muscles was 72.16% and 65.55%, respectively, indicating greater symmetry in the temporalis muscle. Additionally, group 3 displayed the highest mean deviation in both left and right-sided synergic activity of the muscles. The total deviation for the right and left sides was 64.34% and 65.67%, respectively. CONCLUSION The findings suggest that sugar-free chewing gums elicit increased muscle activity compared to sugar-containing chewing gums. Furthermore, the utilization of calorie-free chewing gums with a firm texture was associated with better-coordinated muscle activity. These results provide valuable insights into the effects of different chewing gums on masticatory muscle function and coordination, which may have implications for therapeutic interventions and oral health management.

Abstract
PURPOSE We evaluated oral frailty (OFr) and its association with health-related quality of life (HRQoL), energy and protein intake, and survival among older long-term care residents. METHODS This cross-sectional study with a 3-year follow-up for survival assessed 349 residents in long-term care facilities (73% female, mean age 82 years). We defined OFr with six signs (dry mouth, food residue on oral surfaces, unclear speech, inability to keep mouth open or pain expression during the clinical oral examination, diet pureed/soft) and OFr severity was categorized as Group 1, (mild) = 0-1 signs, Group 2 (moderate) = 2-4 signs, and Group 3 (severe) = 5-6 signs. We measured HRQoL with 15D instrument, and energy and protein intake by a 1- to 2-day food record. Mortality was retrieved from central registers on March 2021. RESULTS Of the residents, 15% had 0-1, 67% 2-4 and 18% 5-6 OFr signs. HRQoL decreased linearly from Group 1 to Group 3. OFr correlated with such dimensions of HRQoL as mobility, eating, speech, excretion, usual activities, mental function, and vitality. We found no association between OFr categories and energy and protein intake. Survival decreased linearly from Group 1 to Group 3. CONCLUSIONS OFr was common among older long-term care residents and OFr severity predicts poorer outcomes. The six oral signs denoting OFr may be used at the bedside to screen residents at risk for OFr.

Abstract
AIM To enable easy assessment of oral frailty; that is, an overlapping slight decline in multifaceted oral function, in any setting, we developed the oral frailty five-item checklist (OF-5), and examined its predictive validity for increased risks of physical frailty, physical disability and mortality among community-dwelling older adults. METHODS This population-based cohort study randomly selected 2044 residents in Kashiwa, Japan, with no long-term care needs. Baseline data were collected in 2012, and follow-up data were collected in 2013, 2014, 2016, 2018 and 2021. The OF-5 includes five measures: fewer teeth, difficulty in chewing, difficulty in swallowing, dry mouth and low articulatory oral motor skills. Physical frailty was defined according to the Cardiovascular Health Study criteria. Physical disability and mortality determined from the long-term care insurance receipt database were followed for 9 years. RESULTS Of 2031 eligible participants (mean age 73.1 ± 5.6 years; 51.1% women), 39.3% individuals with ≥2 OF-5 points had significantly increased prevalence and new-onset rate of physical frailty. After adjusting for potential confounders, oral frailty, defined as ≥2 OF-5 points, was associated with increased risks of physical disability (adjusted hazard ratio 1.40; 95% confidence interval 1.14-1.72) and mortality (adjusted hazard ratio 1.44; 95% confidence interval 1.11-1.87). The highest adjusted hazard ratios were observed in older adults with coexisting physical and oral frailty. CONCLUSIONS The OF-5 showed strong predictive validity for physical frailty, physical disability and mortality in Japanese older adults. This assessment tool can be implemented in various settings and foster comprehensive prevention through interprofessional collaboration. Geriatr Gerontol Int 2023; 23: 651-659.

Abstract
OBJECTIVE This study aims to investigate the bone remodelling and resorption in immediate implantation and restoration of clinical implant-supported overdentures. MATERIALS AND METHODS Six adult domestic dogs were divided into 2 groups: In the experimental group, 6 implants were immediately placed in each mandible, the distal end implants were inclined distal to the long axis of the tooth at an angle of 30 degrees, and restored immediately. As the control group, the animals underwent immediate implant placement with single denture restoration, respectively, nontilting and tilting at 30 degrees in the long axis of the tooth. The osseointegration index (OI) and rate of bone ingrowth fraction were measured, and the peri-implant bone remodelling was observed. The marginal bone loss was measured in the slices of bone-implant and analyzed. RESULTS New bone regenerated and had remodelled in each group. The experimental group had no statistically significant differences, when compared with other groups, except the tilted implant control group, in terms of the OI and bone ingrowth fraction. CONCLUSION Obvious bone absorption did not statistically significantly occur in implant-supported overdenture of immediate implant placement and function with satisfactory new bone and OI.

Abstract
OBJECTIVES Preserving sufficient oral function and maintaining aadequate nutrition are essential for preventing physical frailty and the following long-term care. We recently developed the 6-month Comprehensive Awareness Modification of Mouth, Chewing And Meal (CAMCAM) program, in which participants gather monthly to learn about oral health and nutrition while eating a textured lunch together. This study examined whether the CAMCAM program could improve attitude and behavior towards oral health, mastication, and diet as well as ameliorate oral frailty in community-dwelling older adults. DESIGN Single-arm pre-post comparison study. SETTING AND PARTICIPANTS A total of 271 community-dwelling adults (72.3 ± 5.7 years of age; 159 women [58.7%]) in 4 Japanese municipalities were recruited, of which 249 participants (92%) were assessed at the final evaluation. INTERVENTION Participants gathered once a month at community centers to learn about oral health and nutrition while eating a "munchy" textured lunch containing proper nutrition. MEASUREMENTS Oral frailty, frailty, and eating behavior were evaluated with the Oral Frailty Index-8 (OFI-8), Kihon checklist (KCL), and CAMCAM checklist, respectively. Participants were divided into Oral frailty (OF) and Robust groups according to OFI-8 scores. The differences in KCL and CAMCAM checklist results between the OF and Robust groups were statistically tested along with changes in scores after the program. RESULTS KCL and CAMCAM checklist scores were significantly lower in the OF group at the initial assessment. OFI-8 and KCL findings were significantly improved in the OF group after completing the program (all P <0.05). Regarding the CAMCAM checklist, awareness of chewing improved significantly in the Robust group (P=0.009), with a similar tendency in the OF group (P=0.080). CONCLUSION The findings of this pilot study suggest that the CAMCAM program may improve both oral and systemic frailty in addition to attitudes towards chewing, oral health, and meals, especially in individuals with oral frailty. The CAMCAM program merits expansion as a community-based frailty prevention program.

Abstract
BACKGROUND oral frailty (OFr) may be called a syndrome lacking a consensus on its definition. OBJECTIVE the aim was to prove the relationship between OFr to the phenotype of frailty, general health and nutrition in long-term care. DESIGN the FINnish ORAL Health Study in Long-Term Care study is a cross-sectional clinical research comprising findings on oral and general health and nutrition. SETTING participants were divided into groups according to the number of OFr signs: Group 1 (0-1 sign), Group 2 (2-4 signs) and Group 3 (5-6 signs). SUBJECTS the study includes data on 349 older residents of long-term care facilities in Helsinki, Finland. METHODS frailty status was defined according to Fried's frailty phenotype. OFr was evaluated with six signs: dry mouth, diet of pureed or soft food, residue of food on oral surfaces, unclear speech, inability to keep mouth open during the clinical oral examination and pain expression during the examination. RESULTS a significant linear relationship across the OFr groups with Fried's frailty phenotype was found (P for linearity = 0.008, adjusted by gender and age). A linear trend existed between OFr groups and general health; prevalence of dementia and malnutrition increased from Group 1 to Group 3. The need for help with eating and oral hygiene procedures increased from Group 1 to Group 3. Moreover, OFr had a linear relationship with chewing and swallowing difficulties. CONCLUSIONS OFr is related to Fried's frailty phenotype, general health, nutrition and need for help with daily activities.

Abstract
This retrospective case-control study evaluated the prevalence of declined swallowing function and the association with oral functions and gender in community-dwelling elderly patients. Their profiles, the results of swallowing function (Eating Assessment Tool: EAT-10) and other oral functions (oral dryness, maximum occlusal force (MOF), tongue-lip motor function (oral diadochokinesis: ODK), maximum tongue pressure (MTP) and masticatory performance (MP)) were extracted for analyses. The patients were categorized into three groups according to EAT-10 score (Group 1: 0, Group 2: 1 and 2, Group 3: ≥3). In total, 242 patients were enrolled and 46 of them (19.0%) were categorized into declined swallowing function (Group 3). In two-group comparisons (Group 1, 2 versus Group 3), significant differences were identified in age and the number of remaining teeth, but they were not identified in three-group comparisons. The patients with declined swallowing function (Group 3) had significantly lower function in ODK and MTP. Multiple logistic regression analyses identified that declined swallowing function was independently associated with declined functions in ODK /ka/ (OR: 5.31, 95% CI: 1.03-27.23, p = 0.04) and in MTP (OR: 2.74, 95% CI: 1.12-6.66, p = 0.03). This study could confirm the critical role of tongue functions in swallowing in community-dwelling elderly patients.

Abstract
BACKGROUND Although various training methods have been reported for improving oral function such as occlusal force, there are few reports that show the training effect of eating hard food on the oral functions. OBJECTIVE To examine the training effects of habitually ating hard gummy candies on oral functions. METHODS Participants of this cohort study were recruited into a training (six women, eight men; mean age 27.6 ± 3.5 years) and control group (two women, seven men; mean age 28.3 ± 4.9 years). The training group ate nine custom-developed hard gummy candies three times per week for 3 months. Training effects were evaluated by measuring the maximal occlusal force, masticatory performance, maximal tongue pressure, number of chewing cycles until swallowing the candy, duration of chewing and cycle time before training, after 1, 2 and 3 months of training, and 1 month after stopping training. The iEMG/force, which evaluates masseter muscle hypertrophy with electromyograms (EMG), was calculated. RESULTS Masticatory performance after 1 month (p = 0.01), maximal occlusal force after 2 months (p < 0.01) and maximal tongue pressure after 3 months of training were significantly increased (p = 0.02), and the cycle time after 2 months of training (p = 0.02) was significantly decreased compared to before the intervention. Except for masticatory performance, the other effects were maintained for 1 month after stopping training. Changes in iEMG/force were not significant, but a tendency for muscle hypertrophy was observed in the training group. CONCLUSION Habitual eating of hard gummy candies is a task-specific training that can improve overall masticatory function, including tongue pressure.

Tanaka T, Hirano H, Ohara Y, Nishimoto M, Iijima K. Oral Frailty Index-8 in the risk assessment of new-onset oral frailty and functional disability among community-dwelling older adults. Arch Gerontol Geriatr 2021; 94:104340. [PMID: 33529863 DOI: 10.1016/j.archger.2021.104340] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 12/23/2020] [Accepted: 01/11/2021] [Indexed: 01/08/2023]
Abstract
BACKGROUND Oral frailty is associated with the loss of oral function and increased care needs. We have previously developed an Oral Frailty Index (OFI-8) to identify older adults at risk of oral frailty. Herein, we aimed to examine whether OFI-8 scores are indicative of oral frailty or functional disability risk in community-dwelling older adults. METHODS A total of 2,011 individuals (51% women; mean age, 73.0 ± 5.5 years) participated in the 2012 baseline survey (last follow-up wave 2018). Oral frailty was assessed at each time point, based on tooth status, oral function, and other subjective measures. Functional disability was defined as long-term care certification granted during 2012-2019. The OFI-8 items were assessed at baseline. RESULTS The prevalence and incidence rates of oral frailty at baseline and 6 years were 16% and 24%, respectively. The area under the receiver operating characteristic curve of OFI-8 was 0.88 with 95% confidence interval of 0.86-0.90 for oral frailty. The OFI-8 score of ≥4 points maximized the sum of sensitivity and specificity values. The corresponding positive rate, sensitivity, specificity, positive, and negative predictive values were 30%, 80%, 80%, 43%, and 95%, respectively, for baseline oral frailty. A 1-point increase in the OFI-8 score corresponded to a 1.3-fold increase in the risk of new-onset oral frailty and 1.1-fold increase in the risk of disability. CONCLUSIONS OFI-8 may help identify individuals at risk of oral frailty and functional disability. It may also increase the awareness of oral care and facilitate its uptake.

J Oral Rehabil 2020; 48:411-421. [PMID: 33128790 DOI: 10.1111/joor.13122] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 10/26/2020] [Indexed: 11/30/2022]
Abstract
The deterioration of oral function to a state of oral hypofunction (OHF) is reportedly associated with malnutrition and frailty. Thus, we Investigated the association of OHF with physical characteristics and function and test the effects of a programme including comprehensive oral and physical exercises and textured lunch gatherings (COPE-TeL programme) on oral and physical function in older adults with OHF. Eighty-six community-dwelling older adults were randomly assigned into control (n = 43) or intervention (n = 43) groups. The participants were further divided into OHF and normal oral function (NOF) sub-groups based on initial oral examinations. The intervention group participated in the 12-week COPE-TeL programme, while the control group performed the physical exercise regimen only. The differences in measured variables for physical and oral function between the OHF and NOF groups were statistically tested, and changes in the proportion of participants with OHF were examined. Physical function, such as hand grip strength and walking speed, was significantly lower in the OHF group at the initial assessment. The proportion of participants with OHF was 56% in the intervention group and 67% in the control group before the trial, which became significantly reduced after completing the COPE-TeL programme in the intervention group (26%, P = .002), but not in the controls (61%, P = .549). Older adults with OHF may have diminished physical function. The COPE-TeL programme of oral and physical exercises along with textured lunch gatherings may be effective for older adults with OHF.

Chang MY, Lee G, Jung YJ, Park JS. Effect of Neuromuscular Electrical Stimulation on Masseter Muscle Thickness and Maximal Bite Force Among Healthy Community-Dwelling Persons Aged 65 Years and Older: A Randomized, Double Blind, Placebo-Controlled Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17113783. [PMID: 32466588 PMCID: PMC7312302 DOI: 10.3390/ijerph17113783] [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: 04/27/2020] [Revised: 05/25/2020] [Accepted: 05/25/2020] [Indexed: 12/16/2022]
Abstract
Aim: This study investigated the effect of neuromuscular electrical stimulation (NMES) on masseter muscle thickness and maximal bite force among healthy community-dwelling elderly persons older than 65 years. Materials and methods: A total of 40 participants were randomly assigned to the experimental and placebo groups. In the experimental group, NMES was applied to both masseter muscles, and electrical signals were gradually increased until the participants felt a grabbing sensation (range 6.0–7.5 mA) in the masseter muscle. The placebo group, in contrast, underwent NMES in the same manner and procedure as the experimental group with less electrical intensity (0.5 mA). All interventions were administered five times a week for six weeks, 20 min per day. The outcomes were masseter muscle thickness assessed using ultrasound and maximal bite force using a bite force meter. The level of significance was set as p < 0.05. Results: The experimental group showed a significant increase in both masseter muscle thickness and maximal bite force as compared with the placebo group (p = 0.002 and 0.019, respectively). Moreover, the degree of change in the masseter muscle thickness and maximal bite force significantly increased in the experimental and placebo groups (p < 0.001, both). Conclusions: This study demonstrated that NMES could be an effective modality for increasing masseter muscle thickness and maximal bite force in healthy older adults.
