Understanding poor oral health among older adults in Türkiye: socioeconomic and healthcare access challenges

BACKGROUND

Oral health is an integral part of overall well-being, and older individuals are particularly vulnerable due to age-related changes and barriers to healthcare access. Despite Türkiye's comprehensive public health insurance system, significant disparities in oral health persist, highlighting the need for targeted research and interventions. This study assesses the oral health of people aged 65 and older in Türkiye and explores the factors linked to poor oral health, such as individual characteristics, lifestyle, socioeconomic status, social support, overall health, and access to healthcare services.

METHODS

A secondary analysis was performed using the cross-sectional 2022 Türkiye Health Survey, which gathered data from 3,144 individuals aged 65 and above. Oral health was self-reported, with poor oral health defined as participants rating their dental and gum condition as 'bad' or 'very bad.' Factors assessed included age, gender, education, social support, healthcare access, and the presence of chronic diseases.

RESULTS

Among the participants, 25.8% reported poor oral health. Key factors associated with this included being older, female, having lower levels of education, difficulty communicating in one's mother tongue, experiencing limitations in daily activities, and facing cost-related barriers to dental care. Multivariable analysis found that cost related barriers and limitations in daily activities had the strongest impact on oral health. The study also highlighted the importance of social support in maintaining better oral health.

CONCLUSIONS

Poor oral health in older adults in Türkiye is strongly influenced by cost-related barriers, limitations in daily activities, and lack of social support. Expanding public dental services, reducing out-of-pocket costs, and integrating oral health into chronic disease programs are critical steps. Providing culturally sensitive and mobile care options can also address mobility challenges and enhance oral health outcomes for the elderly.

Migrant-Local Differences in the Relationship Between Oral Health, Social Support, and Loneliness Among Older Adults in Weifang, China: Cross-Sectional Study

Background

Increased aging and accelerated urbanization have led to the migration of older adults within China. Migrant older adults (MOAs) may experience physical and psychological discomfort in influx cities, and they are a vulnerable group that has emerged in the course of fast urbanization. Previous studies have confirmed the association between oral health and loneliness as well as the relationship between social support and loneliness; however, no research has been done to clarify the underlying mechanisms and the migrant-local difference between oral health, social support, and loneliness.

Objective

This study aimed to test the association between oral health, social support, and loneliness among Chinese older adults, as well as the migrant-local difference on the above relationship.

Methods

Multistage cluster random sampling was used to enroll a total of 1205 participants, including 613 MOAs and 592 local older adults (LOAs). Loneliness was assessed by the 6-item short-form UCLA Loneliness Scale; oral health was measured via the Chinese version Geriatric Oral Health Assessment Index (GOHAI); social support was evaluated by the Social Support Rating Scale (SSRS). Descriptive analysis, χ2 tests, and t tests were conducted. Multigroup structural equation modeling (SEM) was employed to clarify the migrant-local difference on the association between oral health, social support, and loneliness among MOAs and LOAs.

Results

The mean score of loneliness was 8.58 (SD 3.032) for MOAs and 8.00 (SD 2.790) for LOAs. Oral health and social support were found to be negatively related to loneliness among MOAs and LOAs; the standardized direct effects for MOAs were -0.168 and -0.444 (P<.001), and they were -0.243 and -0.392 (P<.001) for LOAs, respectively. Oral health generated a direct positive effect on social support, and the direct effect was 0.186 for MOAs (P<.001) and 0.247 for LOAs (P<.001).

Conclusions

Loneliness was fairly low among older adults in Weifang, China, while MOAs showed higher loneliness than LOAs. Oral health had both direct and indirect negative effects on loneliness among MOAs and LOAs, with no significant path differences between MOAs and LOAs. Social support was found to be negatively associated with loneliness for both MOA and LOA, while the association was stronger among MOAs than LOAs. Oral health exerted a significantly positive effect on social support for both MOAs and LOAs, while no significant difference existed between them. Measures should be taken by the government, society, and families to increase social support, improve oral health, and further reduce loneliness among MOAs and LOAs.

Association Between Physical Function and Edentulism in Older Adults: Findings from the Indonesian Family Life Survey 2014

This study aimed to determine the association between physical function and edentulism among older adults. The fifth wave of Indonesian Family Life Survey (IFLS-5) data was used. Physical function was evaluated through physical performance, physical capability, and appendicular skeletal muscle mass (ASM). Edentulous was found in 10.96% of 2554 older adults. Low physical performance (OR 2.02, 95% CI 1.32-3.09; P = .001) was shown to be associated with edentulism in the 60 to 69 age group. In the 70 to 79 age group, both low physical performance (OR 1.62, 95% CI 1.04-2.53; P = .033) and 1 dependency in ADL/IADL (OR 1.75, 95% CI 1.02-2.98; P = .04) were significantly associated with edentulism. Two or more dependencies in ADL/IADL (OR 4.02, 95% CI 1.15-13.99; P = .029) demonstrated significant association with edentulism in older adults ≥80 years. These findings highlighted the importance of maintaining natural teeth and improving oral health during the aging process.

Decomposition Analysis of the Prevalence of Denture Use Between Rural and Urban Older Individuals With Edentulism in China: Cross-Sectional Study

BACKGROUND

Edentulism impacts the physical health and quality of life of older individuals. The prevalence, influencing factors, and differences in terms of edentulism in urban and rural areas of China are unclear.

OBJECTIVE

This study investigated the denture-wearing conditions and causes affecting older patients with edentulism in urban and rural areas of China and analyzed the differences.

METHODS

This cross-sectional study included the data of 5139 older individuals (age>65 years) with edentulism obtained from 23 Chinese provinces in 2018. Participants were divided into urban and rural groups based on their household registration. Factors influencing denture use in both groups were explored using binary logistic regression, while factors influencing differences in denture wearing in both groups were explored using the Fairlie decomposition model.

RESULTS

Of the 5139 participants, 67.05% (808/1205) from urban areas and 51.12% (2011/3934) from rural areas wore dentures. In the urban group, participants with a higher level of education (1-6 years: odds ratio [OR] 2.093, 95% CI 1.488-2.945; ≥7 years: OR 2.187, 95% CI 1.565-3.055) or who exercised (OR 2.840, 95% CI 2.016-3.999) preferred wearing dentures, but individuals with BMI<18.5 kg/m2 (OR 0.558, 95% CI 0.408-0.762) or widowed (OR 0.618, 95% CI 0.414-0.921) did not. In the rural group, a higher level of education (1-6 years: OR 1.742, 95% CI 1.429-2.123; ≥7 years: OR 1.498, 95% CI 1.246-1.802), living alone (OR 1.372, 95% CI 1.313-1.663), exercise (OR 1.612, 95% CI 1.340-1.940), high economic status (OR 1.234, 95% CI 1.035-1.472), residence in the eastern area (OR 2.045, 95% CI 1.723-2.427), presence of chronic diseases (1 disease: OR 1.534, 95% CI 1.313-1.793; ≥2 diseases: OR 1.500, 95% CI 1.195-1.882) were positively associated and age≥80 years (OR 0.318, 95% CI 0.247-0.408), BMI<18.5 kg/m2 (OR 0.692, 95% CI 0.590-0.813), and widowed (OR 0.566, 95% CI 0.464-0.690) or other marital status (OR 0.600, 95% CI 0.392-0.918) were negatively associated with denture use. The Fairlie decomposition model revealed that the number of chronic diseases (16.34%), education level (11.94%), region of residence (11.00%), annual income (10.55%), exercise (6.81%), and age (-0.92%) were the main factors responsible for differences between urban and rural edentulism and could explain the difference in the denture-wearing rate (58.48%) between both groups.

CONCLUSIONS

Older individuals with edentulism with a higher education level and who exercise are more willing to wear dentures, while those with BMI<18.5 kg/m2 show a decreased willingness to wear dentures in both urban and rural areas in China. Controlling the number of chronic diseases, improving the education level and annual income, cultivating good exercise habits, and bridging the gap between the economic status of the east and west can narrow the differences in denture wearing among urban and rural older individuals with edentulism.

Having Plans for the Future in Very Old People

This study aimed to investigate the prevalence of having plans for the future among very old people and the factors associated with having such plans. A longitudinal population-based study with home visits for 85-, 90-, and ≥95-year-old participants in Sweden and Finland was used. Multivariate logistic regression and Cox proportional-hazards regression models with a maximum 5-year follow-up period were used. The prevalence of having plans for the future was 18.6% (174/936). More men than women and more people living in Sweden than in Finland had plans for the future. In multivariate models, having plans for the future was associated with speaking Swedish, being dentate, and living in the community in the total sample; speaking Swedish and being dentate among women; and speaking Swedish, having a lower Geriatric Depression Scale score, and urban residence among men. Having plans for the future was associated univariately, but not multivariately, with increased survival.

Oral health inequalities among geriatric population: A systematic review

As per the World Health Organization, governments should aim to accomplish two significant global milestones by 2030: reducing health disparities and granting universal accessibility to healthcare. The aim of this article was to systematically review the inequalities and understand the multifactorial causation of oral health inequalities among the older adults.

Methods

Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) standards were used to carry out the review and is documented in PROSPERO CRD42026695761. Two authors did the search and screening in accordance with the protocol. Electronic databases such as PubMed, Google Scholar, and EBSCOhost articles of the last 10 years were searched for research presenting data on oral health status and oral health related quality of life in the elderly population. Quality assessment was performed using the Newcastle Ottawa Scale (NOS) for retrospective and prospective research.

Results

Only 24 studies fulfilled the eligibility criteria and were incorporated into the qualitative synthesis. Multiple aspects of oral health and the related variables influencing disparities in oral health in the elderly population living in institutions have a positive link.

Conclusion

The findings support the notion that this demographic consists of weak, dependent individuals who have poor oral health. The vulnerable elderly institutionalized population was recognized and validated, thus helps in providing measures that will eventually focus the risk factors to improve their OHRQoL.

Tooth Loss and Systemic Diseases in the Slovenian Elderly Population: A Cross-Sectional Study of the Associaton Between Oral and Systemic Health

Introduction

This study aimed to assess the prevalence of edentulism and tooth loss in the Slovenian elderly population, along with the associated risk factors, and investigate the association between systemic and oral health.

Methods

The study included 445 individuals aged 65 or older (average age: 79.7±8.9 years). Data on preserved teeth, dental history, chronic diseases, and medications were collected through clinical examinations. Height and weight were recorded in order to calculate body mass index (BMI), and the education level was also collected. Chronic systemic diseases and medications were categorized. Statistical analysis was conducted using linear regression and nonparametric tests.

Results

Participants had an average of 4.7±7.7 teeth, with no significant gender differences. Higher age (β=-0.185, p<0.001) and lower education level (p<0.001) were associated with fewer teeth, while higher BMI showed no correlation (β=-0.085, p=0.325). Diabetes mellitus (p=0.031), cardiovascular diseases (p=0.025), and thyroid diseases (p=0.043) were inversely related to retained teeth. This inverse relationship also applied to individuals who recovered from malignancies, not including head and neck malignancies (p=0.019). No significant relationship was found between osteoporosis and the number of teeth (p=0.573). Notably, antidiabetic drug use was inversely related to the number of teeth (p=0.004), while analgesics showed a positive relationship (p=0.022).

Conclusions

This study highlights the association between specific sociodemographic factors, chronic diseases, and retained teeth among elderly individuals in Slovenia. High edentulism rates among the elderly emphasize the need for enhanced preventive measures and risk factor management, particularly for high-risk groups like the elderly.

Complete Loss of Natural Teeth and Loneliness: A Fixed-Effect Analysis

Psychosocial properties of oral health have been reported. The present study aimed to investigate the causal effect of complete loss of natural teeth on loneliness by using fixed-effects analysis to control for confounding factors, including unmeasured time-invariant factors. Data from older adults participating in at least 2 consecutive waves of the English Longitudinal Study of Ageing in waves 3 (2006/2007), 5 (2010/2011), and 7 (2014/2015) were analyzed (N = 18,682 observations from 7,298 individuals). The association between complete loss of natural teeth and loneliness score (ranging from 3 to 9) was examined using fixed-effect linear regression analysis adjusting for time-varying confounders, including sociodemographic and health characteristics. The prevalence of complete tooth loss was 12.7%, 12.8%, and 10.6% in waves 3, 5, and 7, respectively. Individuals who transitioned to complete tooth loss during any 2 consecutive waves had an increase in loneliness score by 0.27 (95% confidence interval [CI] 0.03, 0.52), which was greater than those who maintained natural teeth (-0.03; 95% CI -0.05, -0.01). Fixed-effects analysis adjusting for time-varying confounders revealed a significant association between complete loss of natural teeth and an increase in loneliness score by 0.31 (95% CI 0.17, 0.46). Complete loss of natural teeth among older adults in England was associated with loneliness, even after accounting for measured time-varying and (un)measured time-invariant confounders. Retaining natural teeth may reduce the risk of loneliness.

Oral health-related quality of life and loneliness: results based on a cross-sectional survey

BACKGROUND

The aim of this study was to clarify the link between oral health-related quality of life (independent variable) and loneliness (outcome) among the general adult population (also stratified by sex).

METHODS

Data were taken from a quota-based survey of the German general adult population (representative in terms of state, sex and age group), with n = 5,000 individuals (mean age was 46.9 years, SD: 15.3 years, ranging from 18 to 74 years). Oral health-related quality of life was quantified using the OHIP-G5. Loneliness was quantified using the De Jong Gierveld tool. Multiple linear regressions were conducted.

RESULTS

After adjusting for several covariates, multiple linear regressions revealed that poor oral health-related quality of life is associated with higher loneliness levels in the total sample (β = 0.12, p < 0.001). Such associations were also found in both sexes (men: β = 0.12, p < 0.001, women: β = 0.12, p < 0.001).

CONCLUSION

Study findings showed an association between oral health-related quality of life and loneliness. Such knowledge is important for addressing individuals at risk for higher loneliness levels. Future research is required to clarify the underlying mechanisms.

Projecting trends in the disease burden of adult edentulism in China between 2020 and 2030: a systematic study based on the global burden of disease

Purpose

This study was based on the Global Burden of Disease (GBD) database and aimed to analyze the trend of disease burden for complete edentulism in Chinese adults between 1990 and 2030, and to provide valuable information for the development of more effective management and preventive measures.

Methods

Data on Chinese adults with complete edentulism from 1990 to 2019 was analyzed using GHDx data. Descriptive analyses were used to analyze changes in the prevalence and burden of complete edentulism, gender and age distribution between 1990 and 2019. In addition, we used an autoregressive integrated moving average (ARIMA) model to predict the trend of disease burden for Chinese adults with complete edentulism between 2020 and 2030.

Results

The incidence, prevalence, and rate of YLDs in adults with complete edentulism in China showed an increasing trend from 1990 to 2019. In 2019, the incidence was 251.20 per 100,000, the prevalence was 4512.78 per 100,000, and the YLDs were 123.44 per 100,000, marking increases of 20.58, 94.18, and 93.12% from 1990. Males experienced a higher increase than females. However, the standardized rates decreased over the same period. The ARIMA model predicts a subsequent upward and then downward trend for all indicators between 2019 and 2030, except for the standardized incidence rate which remained essentially unchanged. Specifically, the incidence is predicted to decrease from 388.93 to 314.40 per 100,000, prevalence from 4512.78 to 3049.70 per 100,000, and YLDs from 123.44 to 103.44 per 100,000. The standardized prevalence and YLDs rates are also expected to decrease.

Conclusion

The burden of complete edentulism in China is projected to show an increasing trend from 2020 to 2022 and a decreasing trend from 2023 to 2030. Despite the decline in the burden of disease associated with complete edentulism in China, many problems remain to be solved.

Spatiotemporal trends of disease burden of edentulism from 1990 to 2019: A global, regional, and national analysis

Background

Understanding the spatiotemporal trends in disease burden of edentulism is critical to reducing disease burden of edentulism and deploying medical resources. We assessed the changing patterns of disease burden of edentulism at global, regional, and national levels from 1990 to 2019.

Methods

Data on incident cases, prevalent cases, disability-adjusted life years (DALYs), and age-standardized rates (ASRs) of edentulism were extracted from the Global Burden of Disease 2019 Study. We calculated the estimated annual percentage change (EAPC) to quantify spatiotemporal trends in the ASRs of edentulism.

Results

In 2019, the number of prevalent cases and DALYs of edentulism were 35.2 and 9.6 million, and the ASPR and ASDR were 43.12/1,000 and 1.18/1,000, with EAPCs of -0.18 [95% confidence interval (CI): -0.28, -0.09] and -0.16[95% CI: -0.26, -0.07] from 1990 to 2019, respectively. Females and the elderly had a higher burden of edentulism. Although the ASPR, ASDR, and ASIR in the high SDI, high-middle SDI, and middle SDI regions showed a decreasing or stable trend, the absolute disease burdens of edentulism in these regions were still high. Although the absolute disease burdens of low SDI and low-middle SDI were low, their ASPR and ASDR showed an upward trend. In countries with high initial disease burden or high SDI, ASPR, ASDR, and ASIR showed stable or declining trends.

Conclusion

The absolute disease burden due to edentulism was increasing in many countries and regions. Countries should reduce the disease burden caused by edentulism by adopting measures including the prevention and treatment of dental caries and periodontal disease.

Income-related inequality and decomposition of edentulism among aged people in China

Background

The aim of this study was to assess the income-related inequality of edentulism among the aged in China and identify the contributing factors.

Methods

A secondary analysis of data from the 4th National Oral Health Epidemiology Survey in China was conducted, and 65–74 years old were selected for the analysis of income-related inequality of edentulism. The concentration curve, Concentration index (CI) and Erreygers-corrected concentration index (EI) were used to represent inequality and its degree qualitatively and quantitatively, respectively. A decomposition method based on probit model was employed to determine the contributors of inequality, including demographic factors, income status, oral health-related knowledge, attitude and practices and self-perceived general health status.

Results

In China, aged people with edentulism were concentrated in the poor. The CI was − 0.2337 (95% CIs: − 0.3503, − 0.1170). The EI was − 0.0413 (95% CIs: − 0.0619, − 0.0207). The decomposition results showed that income (75.02%) and oral health-related knowledge, attitude and practices (15.52%) were the main contributors to the inequality.

Conclusion

This study showed that pro-poor inequality among the elderly with edentulism existed in China. Corresponding policies against the contributors could be considered to promote the health equality of the elders.

Oral Health, Loneliness and Social Isolation. A Systematic Review and Meta-Analysis

OBJECTIVES

Thus far, some empirical studies have investigated the association between oral health and loneliness as well as social isolation. However, a systematic review and meta-analysis is lacking synthesizing this evidence. Hence, our purpose was to close this knowledge gap.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Observational studies examining the association between oral health and loneliness or social isolation were included. Disease-specific samples were excluded.

METHODS

We searched three electronic databases (PubMed, PsycINFO, CINAHL), and did an additional hand search. Data extraction covered methods, sample characteristics and main findings. To evaluate study quality/risk of bias, the NIH tool was used. Study selection, data extraction and assessment of study quality were each conducted by two reviewers.

RESULTS

Seven studies were included in our current work. Several cross-sectional studies and one longitudinal study reported an association between poorer oral health and higher loneliness as well as higher social isolation. The quality of the studies was mostly fair, with two studies of high quality. The pooled OR was 1.47 (95% CI: 1.24-1.75) among the studies with adult samples.

CONCLUSION

Most of the included studies demonstrated an association between oral health and loneliness or social isolation. There is a lack of high quality studies on these associations; in particular, future studies should use longitudinal data to clarify the directionality between oral health and loneliness or social isolation. Prospero registration number: CRD42021268116.

The Association between Oral Health-Related Quality of Life, Loneliness, Perceived and Objective Social Isolation-Results of a Nationally Representative Survey

The aim was to examine the association between oral health-related quality of life and loneliness and perceived as well as objective social isolation. Data were used from a nationally representative survey with n = 3075 (late Summer 2021). The established Oral Health Impact Profile (OHIP-G5) was used to quantify oral health-related quality of life. Moreover, established tools were used to quantify the outcome measures (De Jong Gierveld loneliness scale, Bude/Lantermann scale and Lubben Social Network Scale). It was adjusted for several covariates in regression analysis. Linear regressions showed that low oral health-related quality of life is associated with higher loneliness (B = 0.03, p < 0.001), higher perceived social isolation (B = 0.06, p < 0.001) and higher objective social isolation (B = 0.07, p < 0.05). Further regressions were performed (e.g., stratified by denture usage). Our study stressed the importance of low oral health-related quality of life for loneliness and social isolation (both perceived and objective). This knowledge is important to address individuals at risk. Future studies should clarify the underlying mechanisms.

What variables are associated with use of and need for dental prosthesis? A cross-sectional study

BACKGROUND

Population-based studies assessing the factors associated with use of and need for dental prosthesis among older adults are scarce.

OBJECTIVE

To evaluate the use of and need for dental prosthesis and associated factors in the older adult population of a southern city of Brazil.

MATERIAL AND METHODS

A cross-sectional study, involving community-dwelling older adults (≥60 years), was performed. A probabilistic per cluster sampling was used, and 282 participants from Veranópolis, Brazil, were included. A clinical oral health examination was performed, and a structured questionnaire was applied. Bivariate and multivariate analyses were performed to verify associations using Poisson regression with robust variance.

RESULTS

The prevalence of use of dental prosthesis was 87.2% (n = 246), while the prevalence of need for dental prosthesis was 27% (n = 76). Older adults with medium/high levels of education had 17.8% (P = .019) lower prevalence ratio (PR) for use of dental prosthesis. Unmarried and retired older adults had, respectively, 11.1% (PR:1.111; 95%CI:1.022-1.207) and 19.5% (PR:1.195; 95%CI:1.009-1.415) higher PR for use of prosthesis. Those without access to dental care had 11.8% (P = .012) higher PR for use of dental prosthesis. Older adults living in rural areas had 64.7% (PR:1.647; 95%CI:1.079-2.514) higher PR of need for dental prosthesis.

CONCLUSION

High and low prevalence of use of and need for dental prosthesis, respectively, were detected in this sample. Level of education, marital status, retirement status and access to dental care were associated with the use of dental prostheses. However, only residence area was associated with the need for oral rehabilitation.

Chewing ability and oral health-related quality of life in frail elders after new complete dentures insertion: A paired controlled clinical trial

AIMS

To compare the effect of new complete dentures (CDs) on self-perceived masticatory ability (MA) and oral health-related quality of life (OHRQoL) in frail and nonfrail elders.

METHODS AND RESULTS

Twenty completely edentulous elders were assigned to two groups: frail and nonfrail (n = 10/each). MA was evaluated using a visual analogue scale. OHRQoL was assessed with the Oral Health Impact Profile (OHIP-Edent). Variables were evaluated with volunteers wearing their old and unsatisfactory CDs. Then, a new set of CDs was manufactured and all outcomes were reassessed 2 months after the insertion. Data were analyzed by repeated measures' analyses of variance and Tukey tests. MA for lettuce and peanuts was improved (P < .05) for the frail group after new CD insertion. Psychological discomfort and handicap OHIP-Edent domain improved (P < .05) for both groups after prosthetic treatment. Before treatment, controls reported greater psychological discomfort than the frail group. Meanwhile, the handicap domain score of frail patients improved to a level similar to that of the nonfrail group after treatment. Regardless of frailty, elders showed better MA scores for most food types after treatment and decreased OHIP-Edent domain values.

CONCLUSION

Self-reported MA and OHRQoL of frail elderly people were greatly improved after new CD use.

Income or education, which has a stronger association with dental implant use in elderly people in Japan?

OBJECTIVES

Although inequalities in dental implant use based on educational level have been reported, no study has used income as a proxy for the socioeconomic status. We examined: (i) income inequalities in implant use; and (ii) whether income or education has a stronger association with implant use in elder Japanese.

METHODS

In 2016, a self-reported questionnaire was mailed to participants aged 65 years or older living across Japan as part of the ongoing Japan Gerontological Evaluation Study. We used data from 84,718 respondents having 19 or fewer teeth. After multiple imputation, multi-level logistic regression estimated the association of dental implant use with equivalised income level and years of formal education. Confounders were age, sex, and density of dental clinics in the residential area.

RESULTS

3.1% of respondents had dental implants. Percentages of dental implant use among the lowest (≤ 9 years) and highest (≥ 13 years) educational groups were 1.8 and 5.1, respectively, and among the lowest (0 < 12.2 '1,000 USD/year') and highest (≥ 59.4 '1,000 USD/year') income groups were 1.7 and 10.4, respectively. A fully adjusted model revealed that both income and education were independently associated with dental implant use. Odds ratios for implant use in the highest education and income groups were 2.13 [95% CI = 1.94-2.35] and 4.85 [95% CI = 3.78-6.22] compared with the lowest education and income groups, respectively. From a model with standardised variables, income showed slightly stronger association than education.

CONCLUSION

This study reveals a public health problem that even those with the highest education but low income might have limited accessibility to dental implant services.

The prevalence of edentulism and their related factors in Indonesia, 2014/15

BACKGROUND

Little information exists about the loss of all one's teeth (edentulism) among older adults in Indonesia. The aim of this study was to investigate the prevalence of edentulism and associated factors among older adults in Indonesia.

METHOD

This study examines the self-reported prevalence of edentulism and associated factors among older adults (50 years and older) in a cross-sectional national study using the Indonesia Family Life Survey IFLS-5, 2014/15. The community-based study uses a multi-stage stratified sampling design to interview and assess household members, with a household response rate of over 90%.

RESULTS

The overall prevalence of edentulism was 7.2, 29.8% in 80 years and older and 11.8% in those with no formal education. In adjusted Poisson regression analysis, older age, living in five major island groups and having functional disability were associated with edentulism. In addition, among men, having quit and current tobacco use and among women, having low social capital were associated with edentulism. Further, in adjusted analysis, among men, edentulism was positively associated with hypertension and negatively associated with diabetes, and among women, edentulism was associated with functional disability.

CONCLUSIONS

Results suggest that overall and/or among men or women that older age, living in five major island groups, having functional disability, tobacco quitters and users and those with low social capital was associated with edentulism. The identified associated factors of edentulism may be utilized in oral health programmes targeting older adults in Indonesia.
