TMD and GOHAI indices of Brazilian institutionalised and community-dwelling elderly

Rationale and objectives: Considering the controversy in the literature regarding several aspects of temporomandibular dysfunction (TMD) in elderly populations and the absence of reliable data on elderly Brazilians in this field, this study consisted of an evaluation of TMD prevalence and the self‐perception of oral health among institutionalised and community‐dwelling elderly in São José dos Campos, Brazil. Methods: Two hundred and fifteen community‐dwelling and 185 institutionalised elderly people were evaluated by the Helkimo anamnestic (Ai) and clinical dysfunction (Di) indices and answered a questionnaire using the Geriatric Oral Health Assessment Index (GOHAI). Results: The major prevalence of TMD symptoms was for the Ai0 (symptom‐free) group (69.5%), while the major prevalence of clinical signs was for the DiI (mild) group (56%). Women presented a higher AiII classification than men (χ² test, p = 0.049). Community‐dwelling elderly presented a significantly lower Ai0 classification than the institutionalised ones (Two ratios equality test, p < 0.001). There was no relationship between the institutionalised status and the clinical dysfunction index for Di0 and DiIII classification (Two ratios equality test, p = 0.194 and 0.535 respectively). The institutionalised elderly presented greater (One‐way anova = 0.005) self‐perception of oral health (33.45) than did the community‐dwelling group (32.66). There were only weak Pearson’s correlations among the anamnestic (?33.0%) or clinical (?14.7%) findings by the TMD and GOHAI indices. Symptom‐free (Ai0) institutionalised elderly presented better scores in all GOHAI dimensions and elderly representing an absence of clinical TMD signs (Di0) presented higher GOHAI physical dimension scores in both groups. Conclusions: The prevalence of TMD symptoms among this sample of elderly individuals was relatively low, self‐perception of oral health was reasonable and a weak, inverse correlation was found between TMD signs and symptoms and elderly self‐perception of oral health measured by the GOHAI index.     

CBO guidelines to prevent accidental falls in the elderly: how can it be used in the institutionalized elderly?

Fall incidents occur frequently in the community dwelling elderly and even more in the institutionalised elderly. Fall-related research data indicate positive effects of a multifactorial intervention targeted on prevention of falls and fall-related injuries. In November 2004 the guideline "Prevention of fall incidents in the elderly" developed by The Dutch Institute for Healthcare Improvement (CBO) was published. This guideline pays attention to the risk factors for falling and the prevention of fall incidents in all settings. The highlights for nursing homes are: all nursing home patients are at risk; perform a fall risk assessment to direct fall preventive activities; together with specific fall prevention for the patient general fall prevention for the institute has to be undertaken; a multifactorial approach is indicated. In nursing homes it is possible to perform such approach multidisciplinary.     

Head Turning-Induced Hypotension in Elderly People

Carotid sinus hypersensitivity has a high prevalence in the elderly and is a possible cause of falls. In carotid sinus hypersensitivity, external triggers cause sudden reductions in blood pressure, leading to dizziness or syncope, resulting in falls. Turning of the head is considered an important example of such an external trigger in everyday life, wherein rotation of the neck is thought to manipulate the hypersensitive carotid sinus. However, direct evidence for this is lacking. The aim of this study was to investigate the effects of head turning in elderly with carotid sinus hypersensitivity. We performed a prospective, observational study in 105 elderly patients who visited a geriatric falls clinic in a university teaching hospital and in 25 community dwelling healthy elderly subjects. Continuous measurements of blood pressure and heart rate (Finapres) were performed before, during, and after head turning. Head turning-induced hypotension was defined as a drop in systolic blood pressure of at least 20 mmHg during head turning. Carotid sinus hypersensitivity was examined with carotid sinus massage. We also tested for two other common geriatric hypotensive syndromes, orthostatic hypotension and post prandial hypotension, using active standing and a meal test. All three hypotensive syndromes were defined using consensus definitions. Head turning resulted in hypotension in 39% of patients (mean systolic blood pressure drop 36 mm Hg) and in 44% of the healthy elderly, irrespective of the direction of the head movement. Carotid sinus hypersensitivity was associated with head-turning induced hypotension (OR= 3.5, 95% CI= 1.48 to 8.35). We conclude that head turning is indeed an important cause of sudden drops in blood pressure in elderly with carotid sinus hypersensitivity.

目的:探究老年高血压患者颈动脉内膜中膜厚度(IMT)与动态血压参数间的相关关系,为老年高血压患者的临床治疗提供理论基础。方法:选取2015年1月至2016年1月在我院接受治疗的老年高血压患者204例,根据超声检查结果分为A、B、C三组,每组68例。24 h无创检测患者动态血压参数,包括24h平均收缩压(24h SBP),24 h平均舒张压(24h DBP)、白天平均收缩压(d SBP)、白天平均舒张压(d DBP)、夜间平均收缩压(n SBP)、夜间平均舒张压(n DBP),24h脉压(24h PP)及白天脉压(d PP)、夜间脉压(n PP),记录冠心病的发生率、杓型与非杓型高血压比例,利用Person相关性分析IMT与冠心病发生率及动态血压参数的相关性。结果:收缩压和脉压比较差异均有统计学意义(P0.05),其中B组、C组高于A组,C组高于B组,差异具有统计学意义(P0.05)。非杓型高血压在A组占54.41%,B组占60.29%,C组占79.41%,各组间差异有统计学意义(P0.05);A组、B组、C组冠心病发病率分别为41.18%、54.41%和91.18%,组间比较差异有统计学意义(P0.05)。IMT同冠心病发生率和24h SBP、d SBP、n SBP、24h PP、d PP、n PP呈正相关(r=0.876,0.448,0.378,0.476,0.443,0.491,0.438,P0.05)。结论:老年高血压患者收缩压,脉压升高以及非杓型高血压是造成颈动脉内膜中膜厚度增加的主要原因,同时,IMT与冠心病发病率和动态血压参数间呈正相关关系。     

Extreme winter warming events more negatively impact small rather than large soil fauna: shift in community composition explained by traits not taxa

Extreme weather events can have negative impacts on species survival and community structure when surpassing lethal thresholds. Extreme winter warming events in the Arctic rapidly melt snow and expose ecosystems to unseasonably warm air (2–10 °C for 2–14 days), but returning to cold winter climate exposes the ecosystem to lower temperatures by the loss of insulating snow. Soil animals, which play an integral part in soil processes, may be very susceptible to such events depending on the intensity of soil warming and low temperatures following these events. We simulated week‐long extreme winter warming events – using infrared heating lamps, alone or with soil warming cables – for two consecutive years in a sub‐Arctic dwarf shrub heathland. Minimum temperatures were lower and freeze‐thaw cycles were 2–11 times more frequent in treatment plots compared with control plots. Following the second event, Acari populations decreased by 39%; primarily driven by declines of Prostigmata (69%) and the Mesostigmatic nymphs (74%). A community‐weighted vertical stratification shift occurred from smaller soil dwelling (eu‐edaphic) Collembola species dominance to larger litter dwelling (hemi‐edaphic) species dominance in the canopy‐with‐soil warming plots compared with controls. The most susceptible groups to these winter warming events were the smallest individuals (Prostigmata and eu‐edaphic Collembola). This was not apparent from abundance data at the Collembola taxon level, indicating that life forms and species traits play a major role in community assembly following extreme events. The observed shift in soil community can cascade down to the micro‐flora affecting plant productivity and mineralization rates. Short‐term extreme weather events have the potential to shift community composition through trait composition with potentially large consequences for ecosystem development.     

Oral microbial flora and oral malodour of the institutionalised elderly in Japan

Objectives: To determine the oral health status, especially the level of oral microbial flora and oral malodour, of institutionalised elderly people compared with non‐institutionalised elderly people. Setting: Three institutions and numerous private homes. Subjects: 56 institutionalised and 56 non‐institutionalised elderly people. Main Outcome Measures: Institutionalised elderly people had higher levels of Candida, staphylococci, and oral malodour. Results: Institutionalised elderly people had a higher level of Candida in denture wearers, and a higher level of staphylococci and oral malodour compared with the non‐institutionalised elderly. Conclusion: The institutionalised elderly have a higher risk of opportunistic infections and oral health care should be improved to protect them from these infections and to reduce oral malodour.     

Relationships between depression,lifestyle and quality of life in the community dwelling elderly: a comparison between gender and age groups

This study aimed to comprehensively investigate the comprehensive relationships between depression and the characteristics of lifestyle and quality of life (QOL) of healthy, community dwelling elderly, and compare them according to gender and age groups. 1302 subjects (657 males and 645 females) were used for analysis. The investigators in this study were researchers working at universities in each prefecture. Data collection was conducted in a general delivery survey and interview setting or an education class setting. The geriatric depression scale (GDS) consisting of 15 items with a dichotomous scale was used to assess depression symptoms in the elderly. In addition, 16 items selected from the four factors of economic situation, physical health, social activity, and personal status were used to assess lifestyle. Furthermore, this study investigated life satisfaction, morale, and physical function with the LSI scale, PGC morale scale and the ADL scale of the Ministry of Education, Science and Culture, respectively. According to our results, depression characteristics of the elderly differ between gender and age groups. Depression increases in the old-old elderly rather than in the young-old elderly and is highest in old-old females. The factors significantly related to depression in community dwelling elderly were the number of friends and morale. In particular, an increase in the number of friends was related to a decrease in depression. Depression in the old-old elderly was more significantly related to many lifestyle items compared with the young-old elderly, and especially in the old-old elderly, the extent of social activities related to a decrease in depression.     

Alzheimer's disease,oral function and nutritional status

Objectives: To study differences in nutritional, dental status and oral function between institutionalised patients with Alzheimer's disease and cognitively healthy elderly people living in the community. Design: Comparison was made between two groups, Alzheimer's disease sufferers and healthy controls, using established criteria for anthropometric, mental and dental state. Setting: An institution and residential area in Stockholm, Sweden. Subjects: Forty patients with Alzheimer's disease living in a nursing home and 40 age-and gender-matched control subjects living independently. Intervention: Dental status and anthropometric variables. Results: Overnutrition was less frequent among the demented than the controls and more demented were undernourished. Dental status was similar in the two groups with few edentulous subjects but only 2 of 7 edentulous subjects with Alzheimer's disease wore dentures. Having natural teeth and many functional oral zones is important for food consistency choice, but not for nutritional status. In the Alzheimer group, the stage of dementia has a strong association to the ability to eat unaided and an association with dental status. Conclusion: There are differences in nutritional status between Alzheimer patients in institutions and cognitively healthy elderly living at home. The choice of food consistency is correlated to dental status but nutritional status is not shown to be influenced by dental status. However, the ability to eat unaided is strongly correlated to cognitive status.     

Factors associated with missing teeth in the Brazilian elderly institutionalised population

doi:10.1111/j.1741‐2358.2012.00655.x Factors associated with missing teeth in the Brazilian elderly institutionalised population Objective: Identify factors associated with missing teeth in the elderly institutionalised population in Brazil. Methodology: Cross‐sectional study of elderly institutionalised Brazilians with 1192 subjects. A questionnaire was applied as well as an epidemiological survey of oral health conditions in accordance with WHO. Factorial analysis was carried out with variables related to missing teeth, as well as the Fisher’s exact test, chi‐squared test and multiple logistic regression. Results: Mean age was 76.3 (±9.8), 53.5% (638) of subjects were women and 717 (60.2) were dependent. Mean of Decayed Missing and Filled Teeth Index (DMFT index) was 29.4 (±4.9). The subjects that did not use upper and lower dentures were 61.5% (732) and 79.2% (944), respectively. Median number of missing teeth per person was 27.88 (±6.8) with a mean of 4 (±6.6) teeth present and 2.4 (±4.5) caries‐free teeth. Factors associated with missing teeth following multivariate analysis were: age, sex, self‐assessment of oral health, access to health services, type of institution and area of the country. Conclusions: High level of tooth loss and low level of rehabilitation demonstrate precarious oral health. It is therefore necessary to improve institutional access mechanisms to public health facilities for the institutionalised elderly.     

Prevalence of oral and dental disorders in institutionalised elderly people in Rasht,Iran

doi:10.1111/j.1741‐2358.2009.00313.x
Prevalence of oral and dental disorders in institutionalised elderly people in Rasht, Iran Objective: The aim of this study was to determine the prevalence of dental and oral mucosal lesions in institutionalised elderly people in Rasht. Background: Oral health in the elderly people is important to tailor the health programmes for this increasing age group within the population. Methods: A total of 216 elderly people residing in a geriatric nursing home were included in the study. Subjects were interviewed and examined clinically and registered in a data collection form and analysed using spss version 11 program (SPSS Inc, Chicago, Illinois, USA). Results: The prevalence of dental and oral disorders was 44.9% and 86.1% respectively. The most frequent oral disorders were dry mouth (42.1%), fissure tongue (25.9%), atrophic of tongue (25%), sublingual varicosity (22.7%), burning sensation (16.7%) and varix (15.3%). The prevalence of edentulousness was 56% (95%CI: 49–63%). The mean level of retained teeth was 3.22. The odds of an oral mucosal disorder in females were significantly more than in males (OR = 2.79, 95%CI: 1.25–6.23). Discussion: The findings revealed a high prevalence of dental and oral disorders in institutionalised elderly people in Rasht in comparison to similar studies. The mean of retained teeth was also much lower than in other reports. Therefore, the necessity for regular oral examination of these rapidly expanding age groups of people is essential.     

Tooth loss and associated factors in long-term institutionalised elderly patients

Objective: To compare partial and total tooth loss in dependent institutionalised elderly patients and identify any associated factors. Background: A poor oral health status, together with a reduction of autonomy can seriously affect the general health and increase the risk of death in elderly people. Those with total tooth loss and in need of assistance are the most at risk. Materials and methods: In 2004, a cross‐sectional study of 321 elderly patients was conducted in long‐term hospital services provided in Montpellier, France. Socio‐demographic, behavioural, medical and oral health information was recorded for each patient. Multivariate logistic regression models were performed to test the relationship between those covariates and partial or total tooth loss. Pearson chi‐squared tests were used for bivariate analyses. Results: The proportion of edentulousness was 26.9%; among these12.6% had no dentures. The factors significantly associated with edentulism were: an age ‘older than 87 years’ [odds ratio (OR) = 9.4], the presence of a nephropathy (OR = 6.8), and inadequate oral hygiene (OR = 0.1). The factors most significantly associated with partial tooth loss (at least 21 missing teeth) were ‘cancerous disease’ (OR = 9.9), the presence of a nephropathy (OR = 5.6) and the presence of a neurological disease (OR = 4.1). The factors significantly related to dentate status (20 or more natural teeth retained) were ‘hypertension treatment’ (OR = 2.4), and ‘cortisone treatment’ (OR = 0.2). Conclusion: General health problems as well as a poor oral condition were significant risk indicators for tooth loss among the long‐term institutionalised elderly. This suggests that the number of remaining teeth has a strong effect on oral health‐related quality of life.     

Eight-year mortality associated with dental occlusion and denture use in community-dwelling elderly persons

Objective: To evaluate the influence of dental occlusion, with or without the use of dentures, on mortality in community‐dwelling elderly persons. Subjects: A total of 1030 randomly selected healthy independent elderly aged 65 and over were surveyed in 1995. For the study reported here, subjects were classified into three groups according to the presence or absence of maxillo‐mandibular tooth contacts. Subjects with no maxillo‐mandibular tooth contacts were further subdivided into those with and without dentures. Methods: Data on mortality were obtained from Kure City Council in September 2003. Cox regression models were used in analysing the risk for death with gender and age as covariates. Results: Individuals whose teeth had contact in at least the bilateral premolar regions at baseline had 0.78 times (95% CI: 0.60–0.99) smaller risk for death during the succeeding 8 years than those who had no occlusion. Among those who had no occlusion with their own teeth, the risk for mortality among denture non‐users was 1.52 times (95% CI: 1.25–1.83) higher than the risk for denture users. Conclusion: These results may support the view that, in the elderly, poor dental occlusion is associated with an increased risk for mortality and that, in the edentulous, the use of dentures is associated with a decreased risk for mortality.     

Tooth loss, denture wearing and associated factors among an elderly institutionalised Brazilian population

Objective: This cross‐sectional study assessed the prevalence and extent of tooth loss as well as denture wear and associated factors in institutionalised elderly in Brazil. Background: There is scarcity of research in Brazil concerning geriatric oral health issues. Material and methods: A sample of 335 individuals over 60 years of age, representative of the institutionalised elderly from Belo Horizonte, Brazil, were selected through a stratified sampling strategy. Data were collected from structured questionnaires, reviews of medical records and intra‐oral examinations. Results: Edentulousness was observed in 74.9% of the elderly and was related to age, years of study, income, length of institutionalisation, systemic diseases and mini‐mental score. Among the dentate subjects, 17.9% possessed 20 or more teeth. Approximately half the edentulous elderly (42.6%) and most of the partially dentate subjects (66.7%) did not wear dentures. The multivariate analysis showed that subjects that wear dentures were more likely to be female, possess higher incomes, be more functionally independent and married. Furthermore, the odds of wearing dentures among the elderly who had lost 13–32 teeth were 9.11 times higher than those who had lost up to 12 teeth. Conclusion: Tooth loss is highly prevalent in this institutionalised Brazilian population, and the prevalence of denture wear is low. The extent of tooth loss, income, functional status and marital status are important predictors for denture wear. The development of an oral health programme for these individuals should assist in their rehabilitation needs and promote in‐home care or safe transport for the elderly to a health care location.     

Relationship between periodontal status and intellectual function among community-dwelling elderly persons

doi: 10.1111/j.1741‐2358.2011.00483.x
Relationship between periodontal status and intellectual function among community‐dwelling elderly persons Objective: The aim of this study was to indicate the relationship between periodontal status and intellectual function in the elderly. Background: Periodontal status has been shown to be related to demographic, socioeconomic, and psychological status. Intellectual function is a significant indicator of health status. Nevertheless, the relationship between periodontal status and intellectual function has not been elucidated in detail among the elderly. Materials and Methods: A total of 152 community‐dwelling elderly persons, aged 70–74 years, were enrolled in the study. Periodontal status was evaluated using the WHO Community Periodontal Index of Treatment Needs (CPITN). Intellectual function was assessed by four neuropsychological tests: Raven’s Coloured Progressive Matrices (RCPM) test, the Verbal Paired Associates 1 (VerPA) task and the Visual Paired Associates 1 (VirPA) task, extracted from the Wechsler Memory Scale Revised Edition, and the Block Design subtest, extracted from the Wechsler Adult Intelligence Scales, Third Edition. Correlations between CPITN and each test were examined using Spearman rank correlation coefficients. The ordinal regression model was constructed with CPITN as the dependent variable and neuropsychological test as the principal independent variable to adjust for demographic factors, general health, lifestyle and oral health behaviour. Results: Significant correlations were found between the RCPM test, the VerPA task, the Visual Paired Associates 1 and CPITN. In the ordinal regression model, CPITN was significantly related to measures of RCPM after adjusting for demographic factors, general health status, lifestyle and oral health behaviour. Conclusion: Intellectual function is considered a significant indicator of periodontal status among community‐dwelling elderly persons.

摘要 目的：对蚌埠市蚌山区老年人群骨质疏松症进行流行病学调查,并探讨骨质疏松症对跌倒风险和认知功能的影响。方法：于2019年11月~2021年4月采用多阶段分层随机抽样的方法,抽取蚌埠市蚌山区的常住居民,调查老年人群骨质疏松症发生率,共发放960份调查问卷,回收941份,回收率为98.02%。根据有无骨质疏松症分为骨质疏松症组和无骨质疏松症组,观察两组跌倒风险和认知功能状况。应用多因素logistic回归分析老年人群发生骨质疏松症的危险因素和保护因素。结果：941例研究对象中,检查出存在骨质疏松症者325人,发病率为34.54%。根据有无骨质疏松症分为骨质疏松症组（n=325）和无骨质疏松症组（n=616）。单因素分析结果显示,老年人群发生骨质疏松症与乳制品和钙片摄入情况、年龄、连续服用类固醇激素超过3个月情况、骨折史、性别、其他慢性病患病情况、体质量指数、婚姻状况、饮茶情况、每天运动情况有关（P<0.05）。多因素logistic回归性分析,结果显示：年龄≥70岁、性别为女性、连续服用类固醇激素超过3个月情况是老年人群发生骨质疏松症的危险因素,而每天运动情况≥30 min、有乳制品和钙片摄入情况、体质量指数≥24 kg/m²是老年人群发生骨质疏松症的保护因素（P<0.05）。骨质疏松症组的跌倒风险评估工具（FROP-Com）评分高于无骨质疏松症组,跌倒效能量表（MFES）评分低于无骨质疏松症组（P<0.05）。骨质疏松症组的简明精神状态检查量表（MMSE）评分低于无骨质疏松症组,画钟试验（CDT）评分高于无骨质疏松症组（P<0.05）。结论：蚌埠市蚌山区老年人群骨质疏松症患病率较高,且受到年龄、性别、连续服用类固醇激素超过3个月情况等因素的影响,而每天运动情况≥30 min、乳制品和钙片摄入情况、体质量指数≥24 kg/m²可减少骨质疏松症患病率,同时存在骨质疏松症的患者其跌倒风险升高,认知功能下降。     

Relationships between higher‐level functional capacity and dental health behaviors in community‐dwelling older adults

doi: 10.1111/j.1741‐2358.2012.00654.x Relationships between higher‐level functional capacity and dental health behaviors in community‐dwelling older adults Objective: The aim of the present study was to elucidate relationships between higher‐level functional capacity and dental health behaviours in community‐dwelling older adults. Background: In ageing society, it is necessary to promote oral health in the elderly, because good oral health is a significant contributing factor to good general health. Higher‐level functional capacity has been considered a crucial factor for successful independent living in the elderly. We hypothesised that functional capacity is a significant indicator of dental health behaviours. Methods: Three hundred and thirty‐eight adults aged 65 years or older were enrolled in this study. Higher‐level functional capacity was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG‐index). Univariate and multivariate models were constructed with dental health behaviours, such as regular visits to a dentist, brushing frequency and use of extra cleaning devices, as the dependent variable, and the total TMIG‐index score and its subcategory scores as the principal independent variable. Results: Univariate logistic regression analysis demonstrated a significant correlation between low TMIG‐index and ‘intellectual activity’ subcategory scores to lack of regular visits to a dentist and not using extra cleaning devices. Using a multivariate model, significant relationships remained after adjusting for a number of variables including demographics, medical status, lifestyle and number of remaining teeth. Conclusion: Intellectual activity of higher‐level functional capacity may be an accurate indicator of dental health behaviours in community‐dwelling older adults. Intellectual activity should be taken into consideration to effectively promote oral health behaviours and oral hygiene in elderly persons living independently.

Relationship between subjective assessment of oral health and medical expenses in community-dwelling elderly persons

doi: 10.1111/j.1741‐2358.2011.00459.x
Relationship between subjective assessment of oral health and medical expenses in community‐dwelling elderly persons Objectives: The increasing medical expenses of elderly persons in Japan’s rapidly ageing society have become a major concern. It is therefore important to elucidate the factors associated with such escalation. Here, we focused on the relationship between subjective self‐assessment of oral health, as an index of general health, and medical expenses (excluding dental repair) under the hypothesis that oral health contributes to general medical expenses. Several studies have shown that oral health status is correlated with general health status among elderly persons. We speculated that oral health status might show a relation with medical costs among elderly persons. However, few studies have investigated this relationship to date. Materials and Methods: Participants were 259 elderly subjects (range: 65–84 years; 120 men, 139 women) residing independently. Subjective assessment of oral health was evaluated by their responses (‘Good’, ‘Not good’ and ‘Not at all good’) on a survey questionnaire. The correlation between subjective assessment of oral health and medical expenditure was analysed using Spearman’s rank method, the Mann–Whitney U‐test and the Kruskal–Wallis test. Medical expenses were used as the dependent variable in multinomial logistic regression analysis with background and intraoral factors as independent variables. Results: A slight yet statistically significant correlation was observed between subjective assessment of oral health and outpatient treatment fees. Conclusion: The findings revealed that subjective assessment of oral health is significantly and independently related to the medical expenses of community‐dwelling elderly persons after adjusting for social background, living environment and physical factors.     

Association between number of teeth, edentulism and use of dentures with percentage body fat in south Brazilian community-dwelling older people

doi: 10.1111/j.1741‐2358.2010.00411.x Association between number of teeth, edentulism and use of dentures with percentage body fat in south Brazilian community‐dwelling older people Objective: To evaluate if poor oral status was associated with percentage body fat in a representative sample of south Brazilian community‐dwelling elderly. Background: Evidence suggests that elders with extensive tooth loss and edentulism present with compromised chewing function, which results in dietary changes. However, few studies have assessed whether poor oral status is associated with percentage body fat in community‐dwelling elderly. Materials and methods: A random sample of 471 south Brazilians =>60 years of age was evaluated. Measurements included a questionnaire to assess socio‐demographic, behavioural, general, and oral health data. Percentage body fat was measured with a Tanita TBF 612 digital scale, which measures foot‐to‐foot bioelectrical impedance; and oral status assessment, by means of oral examinations assessing the number of teeth and use of dental prostheses. Correlates of risk of inadequate percentage body fat were assessed by means of multinomial logistic regression. Results: Edentulous participants were more likely to be underfat [OR: 3.11 (1.27–7.61)] or overfat/obese [OR: 1.82 (1.05–3.16)]. Conclusion: The present study shows that edentulous older people had higher odds for inadequate percentage body fat. The maintenance of teeth had a crucial role in increasing the chance of having an adequate body fat percentage in the study population.
