Abstract
INTRODUCTION Although the relationship between the number of teeth and frailty has been extensively studied, the mediating role of nutrition status in the association between the number of teeth and frailty remains to be clarified. METHODS A number of 6,664 participants lived in the communities of West China were analyzed in our study. Physical frailty was determined based on the phenotype established by Fried. Nutrition status was evaluated using the Mini Nutrition Assessment-Short Form (MNA-SF) scale. Multiple linear regression was employed to evaluate the direct relationships between the number of teeth, nutrition, and frailty. Mediation models and structural equation model (SEM) pathway analysis were used to test the mediating role of nutrition status in the relationship between the number of teeth and frailty. RESULTS Among the 6,664 participants aged over 50 years old, the prevalence of frailty was 6.2%. Multiple linear regression analysis showed a significant total relationship between the number of teeth (β = -0.359, 95% CI: -0.473 to -0.244, p < 0.001) and frailty. After adjusting for MNA-SF scores, the relationship between the number of teeth and frailty remained significant (β = -0.327, 95% CI: -0.443 to -0.211, p < 0.001), indicating a partial mediating effect of nutrition. Mediation analysis verified that nutrition partially mediated the relationship between the number of teeth and frailty (indirect effect estimate = -0.0121, bootstrap 95% CI: -0.0151 to -0.0092; direct effect estimate = -0.0874, bootstrap 95% CI: -0.1086 to -0.0678) in the fully adjusted model. This mediating effect occurred through influencing weight loss, low level of physical activity, and debility. SEM framework pathway analysis confirmed the association between the number of teeth, nutrition, and frailty. CONCLUSIONS Our findings demonstrated that frailty was correlated with the number of teeth and poorer nutritional status, with nutrition partially mediating the correlation between the number of teeth and frailty. Our results supported early nutritional evaluation and intervention in oral health to decrease the risk of frailty.

Liu S, Guo Y, Hu Z, Zhou F, Li S, Xu H. Association of oral status with frailty among older adults in nursing homes: a cross-sectional study. BMC Oral Health 2023; 23:368. [PMID: 37287021 PMCID: PMC10249201 DOI: 10.1186/s12903-023-03009-8] [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: 10/23/2022] [Accepted: 05/03/2023] [Indexed: 06/09/2023] Open
Abstract
BACKGROUND The oral status of an individual is a vital aspect of their overall health. However, older adults in nursing homes have a higher prevalence of frailty and poor oral health, particularly in the context of global aging. The objective of this study is to explore the association between oral status and frailty among older adults residing in nursing homes. METHODS The study involved 1280 individuals aged 60 and above from nursing homes in Hunan province, China. A simple frailty questionnaire (FRAIL scale) was used to evaluate physical frailty, while the Oral Health Assessment Tool was used to assess oral status. The frequency of tooth brushing was classified as never, once a day, and twice or more a day. The traditional multinomial logistic regression model was used to analyze the association between oral status and frailty. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated while controlling for other confounding factors. RESULTS The study found that the prevalence of frailty among older adults living in nursing homes was 53.6%, while the prevalence of pre-frailty was 36.3%. After controlling for all potential confounding factors, mouth changes requiring monitoring (OR = 2.10, 95% CI = 1.34-3.31, P = 0.001) and unhealthy mouth (OR = 2.55, 95% CI = 1.61-4.06, P < 0.001) were significantly associated with increased odds of frailty among older adults in nursing homes. Similarly, both mouth changes requiring monitoring (OR = 1.91, 95% CI = 1.20-3.06, P = 0.007) and unhealthy mouth (OR = 2.24, 95% CI = 1.39-3.63, P = 0.001) were significantly associated with a higher prevalence of pre-frailty. Moreover, brushing teeth twice or more times a day was found to be significantly associated with a lower prevalence of both pre-frailty (OR = 0.55, 95% CI = 0.34-0.88, P = 0.013) and frailty (OR = 0.50, 95% CI = 0.32-0.78, P = 0.002). Conversely, never brushing teeth was significantly associated with higher odds of pre-frailty (OR = 1.82, 95% CI = 1.09-3.05, P = 0.022) and frailty (OR = 1.74, 95% CI = 1.06-2.88, P = 0.030). CONCLUSIONS Mouth changes that require monitoring and unhealthy mouth increase the likelihood of frailty among older adults in nursing homes. On the other hand, those who brush their teeth frequently have a lower prevalence of frailty. However, further research is needed to determine whether improving the oral status of older adults can change their level of frailty.

Zhang XM, Jiao J, Cao J, Wu X. The association between the number of teeth and frailty among older nursing home residents: a cross-sectional study of the CLHLS survey. BMC Geriatr 2022; 22:1007. [PMID: 36585614 PMCID: PMC9805096 DOI: 10.1186/s12877-022-03688-y] [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: 06/26/2022] [Accepted: 12/08/2022] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Given that few studies have explored the association between oral health and frailty among older nursing home residents, the purpose of this study was to assess the association between oral health (i.e., the number of teeth and oral behaviors) and frailty in this population using the Chinese Longitudinal Healthy Longevity Survey (CLHLS). METHODS This was a national cross-sectional study derived from the seventh wave of CLHLS in 2018, consisting of 365 older nursing home residents aged 65 years or older. The frailty index was constructed based on 32 variables consisting of self-rated health status, anxiety, depression, ADL and IADL. Oral health was measured through the number of natural teeth and tooth brushing behavior. Multiple logistic regression was used to identify this association between the number of teeth, oral health behaviors, and frailty. RESULTS The mean age of this sample was 87.6 (SD = 9.5), with 154 (42.2%) males. The prevalence of frailty and edentulism was 71.2% and 33.4%, respectively. Multiple logistic regression analysis found that the likelihood of frailty decreased with an increased number of teeth, with an OR of 0.94 (95% CI: 0.91-0.98). Compared with participants with edentulism, older adults with 1 to 20 teeth had a lower likelihood of frailty (OR = 0.39, 95% CI: 0.17-0.88); these results were also found in older adults with more than 20 teeth (OR = 0.20, 0.07-0.57). Additionally, older adults who brush their teeth regularly have a lower likelihood of frailty than those who never brush their teeth (OR = 0.37, 95% CI: 0.13-0.99). CONCLUSION Older nursing home residents who maintain their natural teeth can help lower the risk of frailty, and regular toothbrushing also contributes to decreasing the risk of frailty. Our study emphasizes the importance of oral health, and cohort studies with large-scale samples to address this important issue are warranted in the future.

Global prevalence of edentulism and dental caries in middle-aged and elderly persons: A systematic review and meta-analysis. J Dent 2022; 127:104335. [PMID: 36265526 DOI: 10.1016/j.jdent.2022.104335] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 09/16/2022] [Accepted: 10/14/2022] [Indexed: 11/06/2022] Open
Abstract
OBJECTIVE The aim of the study was to analyze data collected from studies worldwide on the prevalence of edentulism and dental caries, in community-dwellers aged ≥ 45 years. DATA Inclusion criteria; participants aged ≥ 45 years, community-dwellers. Exclusion criteria; participants aged < 45 years, in nursing homes, data obtained from dental clinics or pre-2005. The quality assessment tool by The National Heart, Lung and Blood Institute for Observational Cohort and Cross-sectional studies was used. Meta-analysis using the random-effects model (95% confidence interval) was done with data on participants who were edentulous and/or had active dental caries and stratified by regions of the world, age and Gross National Income per capita. Limitations in the data arose from several factors such as design of the studies included differences in socioeconomic status and access to health care among different countries. SOURCES Embase, MEDLINE via Pubmed and Scopus, manual searches, from January 2016, restricted to English. Experts from different countries were contacted to identify National oral health surveys (NOHS) conducted from 2010 onwards. STUDY SELECTION Eighty-six papers and seventeen NOHS were selected for data extraction. Majority of the studies (n = 69) were cross-sectional and of fair quality. 1.1%-70%, 4.9% - 98% prevalence of edentulism and dental caries, respectively. 22%, 45% estimated random-effects pooled prevalence of edentulism and dental caries, respectively. CONCLUSIONS Within the limitations of this study, the findings indicate that untreated dental caries and tooth loss are prevalent on a global level with wide variations among different countries, age groups and socioeconomic status. CLINICAL SIGNIFICANCE The findings demonstrate the reality of the new cohort of older adults, with higher tooth retention implying more dental caries incidence and the need for different care strategies to ensure better oral health. Large variations and difficulty in making comparisons among different countries highlight the need for more standardized, regular research.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:2884. [PMID: 35270577 PMCID: PMC8909940 DOI: 10.3390/ijerph19052884] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Revised: 02/27/2022] [Accepted: 02/28/2022] [Indexed: 11/16/2022]
Abstract
This cross-sectional study was conducted to clarify the association between oral frailty (OF) and physical frailty (PF). In total, 308 Taiwanese middle-old (75−84 years) community-dwelling people with cognitive decline were recruited from random rural community health care centers. Eight items were considered for the evaluation of their OF status. The Study of Osteoporotic Fracture index was used for frailty assessment, which revealed that 22% of the participants had PF. In an adjusted model, PF was significantly associated with the OF subdomains of difficult to eat hard food (p = 0.009), choking (p = 0.008), denture use (p = 0.008), and inability to chew hard food (p = 0.001); and high risk of OF (OR = 3.03; p = 0.002). After eight steps with elimination of the least significant independent variable, age (p= 0.008), self-reported health status of fair (p = 0.000) and poor (p = 0.000), mild cognitive impairment (p < 0.001) and denture use (p = 0.011) were found to be the indispensable predictors for PF. The logistic regression model with 5 indispensable variables had a predictive value of 78.2%. Longitudinal analyses are needed to examine whether OF is a risk factor for PF onset.

Abstract
OBJECTIVES This study aimed to explore the association between number of teeth and cognitive frailty in American older adults. DESIGN Cross-sectional study. SETTING Community. PARTICIPANTS The participants were 1,531 community-dwelling older adults aged 60 or older from the NHANES database. METHODS Frailty was assessed using a 49-item frailty index, with a cut-off value for frailty of more than 0.21. Cognitive dysfunction was evaluated by the Digit-Symbol Coding Test (DSCT), with the cut-off being below the lowest interquartile range (scores ≤37). Cognitive frailty was defined as participants who suffered from both frailty and cognitive dysfunction. Oral health indicators included number of teeth and other factors, such as the presence of gum disease, daily use of dental floss, daily use of mouthwash and self-rated oral health. Multivariable logistic regression models were used to explore the relationship between number of teeth and cognitive frailty. RESULTS The mean age of the total sample was 69.67 (SD=6.60) years, and 52.71% (n=807) were female. Our study suggests there was a negative association between number of teeth and cognitive frailty (OR =0.98,95%CI:0.96-0.99, P=0.044) after controlling for potential confounding factors. In addition, older adults with 20 or more teeth had lower odds of being cognitively frail (OR=0.66,95%CI:0.44-0.99, P=0.046) than individuals who had less than 20 teeth. CONCLUSION This study suggests that older adults who have more teeth are associated with a lower risk of cognitive frailty. This finding highlights the importance of maintaining as many teeth as possible throughout life and into old age. Cohort studies will be required in the future to determine this relationship.
