Experience of socioeconomic-related inequality in dental care utilization among Thai elderly under universal coverage

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.

Oral health approach in universal health coverage

OBJECTIVE

This study aimed to map how oral health is addressed within the universal health coverage (UHC).

METHODS

This scoping review followed the Joanna Briggs Institute methodology. Searches included the WHO Library and PubMed, Scopus, Embase, LILACS, and Cochrane databases. Quantitative and qualitative studies were included without publication date and language restrictions.

RESULTS

A total of 486 studies were retrieved, of which 292 were excluded in the title and abstract screening phase; 121 full-texts were assessed. After the removal of duplicates and unavailable documents, 50 studies were included in the review and categorized according to the level of scientific evidence.

CONCLUSION

Few studies discussed oral health within the UHC, mostly because this coverage does not include oral health adequately. When offered, oral health packages are limited and include specific populations. Access and use of oral health services remain guided by economic factors, exposing the theoretical financial protectionism that perpetuates health inequalities.

To appreciate the influence of contributed determinants on dental care utilization in the context of socio-economic inequalities

BACKGROUND

To appreciate dental care utilization in ‌the context of socio-economic inequalities, it is imperative to identify sources of inequalities and evaluate the extent to which dental care utilization is still related to socio-economic status. This study aimed to quantify the influence of contributed determinants on dental care utilization in the context of socio-economic inequalities amongst adults residing in Tehran metropolis.

METHODS

In this cross-sectional community-based study, a stratified random sample of 1,510 subjects aged over 18 years was investigated by the zero-inflated Poisson analysis to measure the effect of determinants on utilization of dental care, and concentration index as well as the decomposition approach to identify the contributions of deterministic variables to the socio-economic inequality. Data was obtained by employing a phone interview survey. Individuals who were not willing or able to answer the questions in the telephone interview due to hearing or neurological problems did not participate in the interview. Dental care utilization was measured using the number of dental appointments.

RESULTS

Gender (male), oral health-related behaviors (such as brushing and dental flossing), experience of toothache, and concern about dental appearance were associated with an increased likelihood of utilizing dental care. Individuals who belonged to advanced age groups and lived alone significantly underutilized dental care. The concentration index equaling 0.05 (SE = 0.05) corroborates a pro-rich inequality. Decomposition analysis demonstrated the impact of oral health-related behaviors (i.e. dental brushing and use of dental flossing), concern about dental appearance, toothache, gender (male), insurance coverage of dental care, and smoking habit on the poor-rich gap in the dental care utilization.

CONCLUSIONS

The influence of socio-economic inequalities on dental care utilization is discernable along the entire spectrum of socio-economic status. Individuals with lower socio-economic status experience more underutilization of dental care. Community subgroups, particularly the more deprived bracket, require consideration from key stakeholders, including policymakers and health professionals for the enhancement of dental care utilization as revealed by underlying determinants.

Factors affecting oral and dental services` utilization among Elderly: a scoping review

BACKGROUND

Regular use of oral and dental services by the elderly is one of the important factors in reducing oral and dental diseases. This study aimed to identify the factors affecting oral and dental services` utilization among elderly.

METHODS

The published articles on the factors affecting oral and dental services` utilization among elderly were found through a scoping search and using related keywords in PubMed, Scopus, Embase, and Web of Science databases within January 2000 - December 2022 according to the PRISMA guidelines. The data were analyzed using the thematic analysis method.

RESULTS

Among the 2381 articles retrieved from the databases, forty-two were extracted. The factors affecting oral and dental services` utilization among elderly were classified into five main components as follows: access, demographic factors, social factors, health level, and mental factors. The results showed that income, education level, living area, number of teeth, and importance of care were the most frequent in the main components of access, demographic factors, social factors, health level, and mental factors, respectively.

CONCLUSION

Equitable utilization of oral and dental services is the right of all members of the society, especially the elderly. Therefore, it is necessary to provide the elderly with suitable conditions to utilize such services, which are mostly luxury items. Furthermore, increasing the elderly's awareness and encouraging them to use oral and dental services regularly can help reduce the burden of oral and dental diseases.

Indicators of integrating oral health care within universal health coverage and general health care in low-, middle-, and high-income countries: a scoping review

BACKGROUND

The World Health Organization (WHO) has recently devoted special attention to oral health and oral health care recommending the latter becoming part of universal health coverage (UHC) so as to reduce oral health inequalities across the globe. In this context, as countries consider acting on this recommendation, it is essential to develop a monitoring framework to measure the progress of integrating oral health/health care into UHC. This study aimed to identify existing measures in the literature that could be used to indicate oral health/health care integration within UHC across a range of low-, middle- and high-income countries.

METHODS

A scoping review was conducted by searching MEDLINE via Ovid, CINAHL, and Ovid Global Health databases. There were no quality or publication date restrictions in the search strategy. An initial search by an academic librarian was followed by the independent reviewing of all identified articles by two authors for inclusion or exclusion based on the relevance of the work in the articles to the review topic. The included articles were all published in English. Articles concerning which the reviewers disagreed on inclusion or exclusion were reviewed by a third author, and subsequent discussion resulted in agreement on which articles were to be included and excluded. The included articles were reviewed to identify relevant indicators and the results were descriptively mapped using a simple frequency count of the indicators.

RESULTS

The 83 included articles included work from a wide range of 32 countries and were published between 1995 and 2021. The review identified 54 indicators divided into 15 categories. The most frequently reported indicators were in the following categories: dental service utilization, oral health status, cost/service/population coverage, finances, health facility access, and workforce and human resources. This study was limited by the databases searched and the use of English-language publications only.

CONCLUSIONS

This scoping review identified 54 indicators in a wide range of 15 categories of indicators that have the potential to be used to evaluate the integration of oral health/health care into UHC across a wide range of countries.

Change in Denture Procedures after Implementation of National Health Insurance Coverage for the Elderly in Korea: A Nationwide Database

Background: Dental health is an important factor in daily life routines and is closely associated with maintaining a health-related quality of life. This study examined denture procedure changes after implementation of the National Health Insurance (NHI) Coverage of Dentures for the elderly. Methods: We used the “Korean Community Health Survey (KCHS)” developed by the Korea Centers for Diseases Control and Prevention. We analyzed the association between policy implementation and dental health-related outcomes using difference-in-differences (DID) analysis to compare patients aged ≥75 with those 65–74 years before and after coverage. Results: A comparison of age groups and coverage periods showed that patients aged ≥75 years had higher (OR: 1.038, 95% CI: 1.021–1.055) procedure rates after coverage. In particular, elderly patients on medical aid had significantly higher denture procedure rates, while those without oral health screening were more likely to have denture procedures. Conclusions: This study determined the impact of the NHI Coverage of Denture procedure policy for the elderly and found increased denture treatments in the elderly. This policy appeared to positively affect older patients by increasing denture procedures for low-income and medical aid beneficiaries. Hence, the government needs to increase oral health examination and dental health policies for the elderly.

Social backgrounds, oral behaviors and dental service utilization among Thai older adults: data from the national oral health survey

Purpose

The number of older adults in Thailand is currently increasing. To create the appropriate oral health service for this age group requires an understanding of the factors that are associated with their dental service utilization. This study aimed to determine the associations between social backgrounds, oral behaviors and dental service utilization among Thai older adults.

Design/methodology/approach

This was a cross-sectional study on a representative sample of older adults in the 8th Thai National Oral Health Survey (TNOHS). Data of 4,130 Thai older adults were collected through interviews. The association between social backgrounds, oral behaviors and dental service utilization were investigated using chi-square and logistic regression models.

Findings

Of the older adults aged 60–74 years old, 38.4% had used dental services in the last 12 months. Smokers used dental services the least (32.1%). Location, income, education and social welfare were significantly associated with dental service utilization. Among the oral behaviors evaluated, smoking was significantly associated with low dental service utilization.

Originality/value

Thai older adults with a poor social background including location, income, education, entitlement to the Universal Coverage Scheme (UCS) and smoking made less use of dental services.

Predisposing and enabling factors associated with public denture service utilization among older Thai people: a cross-sectional population-based study

Backgrounds

Tooth loss is one of the major oral health problems among older Thai people. However, there is the existence of socioeconomic-related inequalities in dental service utilization, especially denture service. The aim of this study was to assess the determinants associated with inequalities in denture service utilization among older Thai people using the Andersen Behavioural model.

Method

This cross-sectional study involved secondary data analysis of the 2014 survey of older Thai people (N = 38,695). The dependent variable was a public denture service utilization over the past 5 years. Determinants were classified as predisposing and enabling factors. Predisposing variables included age, sex, education, economic condition and dependency status. Enabling variables included working status, health behaviours, health care utilization experience and social/community support. Data were analysed by using bivariate and multivariable analyses at α = 0.05. For bivariate analysis, chi-square test was used to determine the association between dependent and each independent variable. Then, all variables were incorporated into a multivariable binary logistic regression.

Results

The odds of denture service utilization were significantly higher for individuals who were older, female, and had a higher educational level and health-promoting behaviors. A positive dose-response relationship was demonstrated between denture service utilization and increased quartile of household assets.

Conclusions

Predisposing variables had a greater impact than enabling variables in denture service utilization among older Thai people. Despite free public denture service, socioeconomic-related inequalities persist. The government needs to reduce socioeconomic disparities to improve denture treatment inequality.

Oral healthcare systems for an ageing population: concepts and challenges

Oral healthcare systems (OHCS) are designed to maintain the health and function through Communication (Health promotion and education), Prevention, Assessment and Diagnosis, and Treatment. The complexity of these OHCS functions for the ageing are described utilizing the spectrum of dependency of the Seattle Care Pathway framework. Barriers and disparities which challenge the development of OHCS for the ageing can be universal but often vary between developed and developing countries. Recognizing that oral diseases are largely preventable, strategies to improve OHCS must be targeted locally, nationally, and internationally at oral health policy, education, research, and clinical care.

Disparities in dental healthcare utilization in China

OBJECTIVES

The goal of this study was to investigate inequality in dental service utilization in Chinese middle-aged and senior adults and changes in inequality over time and to determine the sources of inequality.

METHODS

The data included 17 648 individuals aged 45 years and older in 2013 and 15 450 individuals in 2015 who participated in the China Health and Retirement Longitudinal Study (CHARLS). The concentration index was used to quantify the degree of inequality. A decomposition method was employed to determine the sources of inequality, including need variables (demographic characteristics, self-reported health status, and presence of chronic diseases), living standard (measured by household consumption expenditure per capita), other non-need variables (education level, marital status, region of residence, urban-rural difference and type of health insurance plans).

RESULTS

The better-off not only had a higher likelihood of using dental care services than did the worse-off but also used them more often than the worse-off. The concentration index for probability of dental care utilization increased from 0.074 to 0.112 between 2013 and 2015, and the concentration index for total number of dental visits increased from 0.085 to 0.127. Living standard, education, health insurance plans and urban-rural disparities showed a pro-rich contribution to the inequality. The living standard contributed about 70% to the pro-rich inequality.

CONCLUSIONS

Dental care utilization in the Chinese middle-aged and older adults was concentrated in the better-off. Inequality in dental care utilization widened from 2013 to 2015. Achieving equity in dental care utilization remains a challenge for the healthcare system in China.

Effect of socio-economic factors in utilization of different healthcare services among older adult men and women in Ghana

BACKGROUND

The older adult population is increasing all over the world. In sub-Saharan Africa, due to poverty and low policy coverage, older adults are not well catered for. The effect of socio-economic inequality in the use of healthcare services among older adult men and women in Ghana was investigated in this paper.

METHODS

The data employed in the study were drawn from Global Ageing and Adult Health survey SAGE Wave 1 Ghana and was based on the design for the World Health Survey 2003, SAGE Wave 0, Ghana. The survey was conducted in 2007-2008 and collected data on socio-economic characteristics and other variables of the 5573 individuals interviewed.

RESULTS

Using generalized logit model, the study found that health status is a very strong determinant of the type of healthcare services preferred by older adults Ghanaians. Men with higher income preferred the private health facilities, while those who completed tertiary education, those with health insurance and those who self-rated their health as very bad, bad or moderate preferred public facility. Self-employed men and those in informal employment, preferred other health facilities outside the formal public health service. Women with primary and secondary education, preferred the private health facilities. Women with health insurance, those in middle and upper class income quintiles or those with self-rated bad and moderate health status or being relatively younger preferred the public facility to other health services. Self-employed women and those in informal employment preferred traditional treatment. In Ghana, there are important socio-economic gradients in the use of some healthcare services. In both sexes, those without insurance and rural residents preferred the pharmacy and traditional treatment.

CONCLUSION

These differences may be due to socio-economic inequities but could also indicate that the existing health facilities are not always used in an optimal way. Patient factors may be equally important as supply factors in explaining the differential use of health services. The public health systems in Ghana still have a major role in improving the health of older adults. National commitments in providing basic essential infrastructure and personnel to health centres for the citizenry is imperative. Policy readjustment of the national health insurance scheme to make it truly accessible to the aged is essential.

Changes in socioeconomic inequalities in the use of dental care following major healthcare reform in Chile, 2004-2009

The study examines changes in the distribution and socioeconomic inequalities of dental care utilization among adults after the major healthcare reform in Chile, 2004-2009. We evaluated the proportion of people who visited the dentist at least once in the previous two years, and the mean number of visits. These outcome variables were stratified by sex, age (20-39, 40-59, 60-63; ≥64 years), educational level (primary, secondary, higher), type of health insurance (public, private, uninsured), and socioeconomic status (quintiles of an asset-index). We also used the concentration index (CIndex) to assess the extent of socioeconomic inequalities in the use of dental care, stratified by age and sex as a proxy for dental care needs. The use of dental care significantly increased between 2004 and 2009, especially in those with public health insurance, with lower educational level and lower socioeconomic status. The CIndex for the total population significantly decreased both for the proportion who used dental care, and also the mean number of visits. Findings suggest that the use of dental care increased and socioeconomic-related inequalities in the utilization of dental care declined after a Major Health Reform, which included universal coverage for some dental cares in Chile. However, efforts to ameliorate these inequalities require an approach that moves beyond a sole focus on rectifying health coverage.

Longitudinal associations between oral health impacts and quality of life among a national cohort of Thai adults

BACKGROUND

There is limited evidence on the association between oral health and general health in middle-income countries. This study analysed data from 60,569 adult students enrolled at Sukhothai Thammathirat Open University and residing throughout Thailand who reported oral health impacts at the 2005 baseline and 2009 health status based on Short Form (SF-8) survey.

FINDINGS

In 2005, 16.4% had difficulty chewing and/or swallowing, 13.4% reported difficulty speaking and/or discomfort with social interaction, and 10.8% of the cohort reported having pain associated with teeth or dentures. Cohort members reporting one or more oral health impacts in 2005 had lower SF-8 mean scores in 2009. In particular, monotonic dose-response gradients in 2005-2009 associations based on multivariate linear regression were found between an increase in number of oral impacts (0, 1, 2, 3) and a decline in SF-8 Physical Component Summary scores (adjusted means of 50.5, 49.2, 48.6, 47.9) as well as SF-8 Mental Component Summary scores (adjusted means of 43.2, 40.9, 40.3, 38.6) in younger cohort members. Similar dose response gradients were found in older cohort members.

CONCLUSIONS

We found strong association between oral health impacts and adverse health and quality of life among Thai adults. This finding confirms that oral health is one of the key determinants of population health.

Pure and social disparities in distribution of dentists: a cross-sectional province-based study in Iran

During past decades, the number of dentists has continuously increased in Iran. Beside the quantity, the distribution of dentists affects the oral health status of population. The current study aimed to assess the pure and social disparities in distribution of dentists across the provinces in Iran in 2009. Data on provinces’ characteristics, including population and social situation, were obtained from multiple sources. The disparity measures (including Gini coefficient, index of dissimilarity, Gaswirth index of disparity and relative index of inequality (RII)) and pairwise correlations were used to evaluate the pure and social disparities in the number of dentists in Iran. On average, there were 28 dentists per 100,000 population in the country. There were substantial pure disparities in the distribution of dentists across the provinces in Iran. The unadjusted and adjusted RII values were 3.82 and 2.13, respectively; indicating area social disparity in favor of people in better-off provinces. There were strong positive correlations between density of dentists and better social rank. It is suggested that the results of this study should be considered in conducting plans for redistribution of dentists in the country. In addition, further analyses are needed to explain these disparities.
