Density of dental practitioners and access to dental care for the elderly: A multilevel analysis with a view on socio-economic inequality

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.

Frailty as a determinant of dental attendance among community-dwelling older adults

OBJECTIVES

The aim of this study was to assess the association between different levels of frailty and dental attendance among home-dwelling older adults, in Belgium.

BACKGROUND

While many determinants of dental attendance among older adults have been identified, no study has focused on the role of frailty.

MATERIALS AND METHODS

This was a cross-sectional study on a random sample of home-dwelling adults aged 60 and over from two Belgian cities. Data were collected with a structured questionnaire through a participatory peer-research method. Time since the last dental attendance was the dependent variable. The independent variable was frailty, assessed with the Comprehensive Frailty Assessment Instrument, including physical, psychological, social, and environmental subdomains. Covariates were age, gender, having a partner, educational level, and household income, as well as self-perceived oral health. Data analysis included descriptive, bivariate (Chi-Square, ANOVA, and Kruskal-Wallis), and binomial logistic regression analyses.

RESULTS

The sample consisted of 1329 older adults with a mean age of 72.5 years (SD 8.9, range 60-103). In the low frailty group, 73% attended the dentist in the previous 12 months, while it was 62% and 54% in the medium and high frailty groups, respectively. In the fully adjusted model, the initial gradient in the relationship between overall frailty and dental attendance remained; those in the medium and the high frailty groups were respectively 1.46 (95% CI: 1.09, 1.95) and 1.67 (95% CI: 1.15, 2.43) times more likely to report no dental attendance in the previous year than the low frailty group. Similar associations could be seen in the physical and environmental frailty subdomains.

CONCLUSION

Frailty is consistently associated with less favourable dental attendance, independent from age, gender, socioeconomic factors, family composition, and self-perceived oral health. Once frailty has been detected, good interprofessional communication and care are needed to avoid the drop-out of older adults from the oral healthcare system.

Trends in dental care utilisation among the elderly using longitudinal data from 14 European countries: A multilevel analysis

BACKGROUND

The use of dental care among older people is low compared to other forms of health care, with significant health consequences. However, the evidence on the extent to which countries' welfare systems and socio-economic factors influence the uptake of dental care by older people is limited. This study aimed to describe trends of dental care utilisation, and to compare use of dental care with other types of healthcare services among the elderly, considering different socio-economic factors and welfare systems in European countries.

METHODS

Multilevel logistic regression analysis was performed using longitudinal data from four waves (between Wave 5 and 8) of the Survey of Health, Ageing and Retirement in Europe database, with a follow-up period of 7 years. The study sample included 20,803 respondents aged 50 years or older from 14 European countries.

RESULTS

The annual dental care attendance was the highest in Scandinavian countries (85.7%), however, improving trends of dental attendance was recognized in Southern and Bismarckian countries (p<0.001). The difference in use of dental care services between socio-economic groups was expanding over time regarding low- and high-income level and residential area. A more marked difference was observed between social groups in dental care utilisation compared to other forms of care. Income level and unemployed status had significant effect on forgoing dental care due to cost and unavailability.

CONCLUSION

The observed differences between socioeconomic groups may highlight the health consequences of the different organization and financing of dental care. The elderly population could benefit from adopting policies aiming to reduce the financial barriers to dental care usage, especially in Southern and Eastern European countries.

Factors associated with the use of dental services in the previous 12 and 36 months by Brazilian older people residing in rural areas

OBJECTIVES

To describe the use of dental services in two periods and associated factors in older people residing in the rural area of a municipality in southern Brazil.

METHODS

This was a cross-sectional study nested in a cohort study. A standardised questionnaire was used to collect the variables of interest. The dependent variables were the use of dental services in the 12 and 36 months prior to the interview.

RESULTS

A total of 863 older people were interviewed, 24.7% of whom had visited a dentist in the previous year and 38.7% had visited a dentist in the previous 3 years. Skin colour, health insurance and self-rated health were associated with both outcomes. Individuals with non-white skin, those who did not have health insurance and those who considered their health to be poor or very poor were more likely to take a long time before seeking oral health services. Differences between the two outcomes were observed in oral health and the use of tobacco. The likelihood of having gone more than 3 years without visiting a dentist was greater among smokers and lower among those with dental caries.

CONCLUSIONS

The prevalence of dental service use was low. Variables related to the adoption of unhealthy behaviours and the occurrence of oral diseases were only related to the use of dental services 36 months prior to the interview. Public policies must be reorganised to prioritise population groups with greater difficulties in the use of dental services.

Inequality in dental care expenditure in Iranian households: analysis of income quintiles and educational levels

Background

Oral health is a major public health issue which affects the human life. Access to dental care is one of the important factors in maintaining oral health. This study was aimed to investigate inequality in dental care expenditure in Iranian households.

Methods

The present study is a secondary analysis of a national cross-sectional survey. The data collected from the Households Income and Expenditure Survey in 2016 and 2017. The final sample consisted of 54,354 households living in rural and urban regions of all the provinces. Inequalities in household’s dental care expenditure per capita in respect to income quintiles and educational level were measured based on the Gini coefficient and concentration index.

Results

The results showed that about 8% of households had paid for dental care during the month before sampling. The Gini coefficient value was estimated to be 0.97 and 0.96 for dental care expenditure per capita respectively in absolute and relative measure. It indicated a significant inequality in the dental expenditure among the sample households. The values of concentration index were positive and significant for all dental care subcategories in respect to the provincial and national income quintiles as well as the educational level of the head of the household.

Conclusions

Income and educational inequality in the both absolute and relative dental services expenditure of the Iranian households were in favor of higher income groups as well as higher educational level of household heads. Income inequality was higher in total dental care expenditure per capita and all its subcategories than the educational inequalities of dental expenditure. In order to reduce these inequalities, the policymakers need to pay special attention to low-income households, particularly those with low-educated heads.

Coprescription Trends in Western Medicine, Chinese Herbal Medicine and Dental Medicine among Older Adults in Taiwan from 1997 to 2013

BACKGROUND

Coprescription is a potential medical problem for older adults that could induce polypharmacy and subsequent complications. In Taiwan, Chinese herbal medicine (CHM) is popular among the older adults. Investigating the coprescription trends in Western medicine, CHM and dental medicine is important to avoid possible polypharmacy.

METHODS

We analyzed data from the Longitudinal Health Insurance Database 2000 (LHID 2000) in Taiwan. Patients ≥ 60 years old who received coprescription of Western medicine, CHM and drugs for dental care from 1997 to 2013 were included. The odds ratio (OR) and 95% confidence interval (95% CI) were estimated by a logistic regression model for evaluating the correlation between baseline characteristics and coprescription.

RESULTS

A total of 266,034 patients were included for the analysis. Most patients receiving coprescriptions lived in the northern Taiwan and with a monthly income lower than 20,000 new Taiwan dollars. The trends in older adults using Western medicine alone or CHM alone decreased over time, but the cohort using dental medicine alone had the opposite result. Decreased trends in coprescription with age were noted. The trends in the proportion of coprescription and the number of days of coprescription increased with the calendar year. Increased trends in the proportion of patients with coprescription were also found, except for the cohort of patients who used both Western medicine and CHM. Patients who were female, and aged 70-79 years were prone to receive coprescription.

CONCLUSIONS

Coprescription in older patients is not uncommon in Taiwan. Healthcare providers and policymakers should be aware of the complex coprescription pattern in the older adults.

Impact of fees on access to dental care: evidence from France

BACKGROUND

For financial reasons, dental prosthetics is one of the major unmet dental healthcare needs [Financial-SUN (F-SUN)]. Private fees for dental prosthetics result in significant out-of-pocket payments for users. This study analyzes the impact of geo-variations in protheses fees on dental F-SUN.

METHODS

Using a nationwide French declarative survey and French National Health Insurance administrative data, we empirically tested the impact of prosthetic fees on dental F-SUN, taking into account several other enabling factors. Our empirical strategy was built on the homogeneous quality of the dental prosthesis selected and used to compute our price index.

RESULTS

Unmet dental care needs due to financial issues concern not only the poorest but also people with middle incomes. The major finding is the positive association between dental fees and difficulty in gaining access to dental care when other enabling factors are taken into account (median fee in the highest quintile: OR = 1.35; P value = 0.024; 95% CI 1.04-1.76). People with dental F-SUN are those who have to make a greater financial effort due to a low/middle income or a lack of complementary health insurance. For identical financial reasons, the tendency to give up on healthcare increases as health deteriorates.

CONCLUSIONS

The results underscore the need for fee regulation regarding dental prosthetics. This is in line with the current French government dental care reform.

General practitioner consultation after a visit to the emergency department: an observational study

BACKGROUND

Some studies have demonstrated an association between poor continuity of care, high likelihood of 'inappropriate' use of emergency departments (EDs) and avoidable hospitalization. However, we lack data concerning primary care use after an ED visit.

OBJECTIVE

Identify the determinants of a visit to the general practitioner (GP) after an ED visit.Methods.

DESIGN

Observational study (single-centre cohort).

SETTING

One emergency department in Paris, France.

SUBJECTS

All adult patients who presented at the ED and were discharged.

MAIN OUTCOME MEASURE

We collected data by the use of a standardized questionnaire, patients' medical records and a telephonic follow-up. Descriptive analyses were performed to compare individuals with and without a GP. Then, for those with a GP, multivariate logistic regression was used to identify the determinants of the GP consultation.

RESULTS

We included 243 patients (mean age 45 years [±19]); 211 (87%) reported having a GP. Among those who reported having a GP, 52% had consulted their GP after the ED visit. Not having a GP was associated with young age, not having complementary health insurance coverage, and being single. GP consultation was associated with increasing age [adjusted odds ratios (aOR) = 1.03], poor self-reported health status (aOR = 2.25), medical complaints versus traumatic injuries (aOR = 2.24) and prescription for sick note (aOR = 5.74).

CONCLUSION

Not having a GP was associated with factors of social vulnerability such as not having complementary health insurance coverage. For patients with a GP, consultation in the month after an ED visit seems appropriate, because it was associated with poor health status and medical complaints.

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.

What Are the Determinants of Dental Care Expenditures in Institutions for Adults With Disabilities? Findings From a National Survey

OBJECTIVE

To analyze the determinants of dental care expenditures in institutions for adults with disabilities.

DESIGN

Health and disability survey and insurance database.

SETTING

Institutional setting.

PARTICIPANTS

Adults (N=2222) living in institutions for people with cognitive, sensory, and mobility disabilities.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

We used a Heckman selection model to correct for potential sample selection bias due to the high percentage of non-dental care users. The Heckman selection model is a 2-step statistical approach based on the simultaneous estimation of 2 multiple regression models-a selection equation (step 1) and an outcome equation (step 2)-offering a means of correcting for nonrandomly selected samples. The selection equation modeled whether the individual had consulted a dentist at least once, whereas the outcome equation explained the dental care expenditures. Disability severity was assessed by scoring mobility and cognitive functional limitations. Regressions also included sociodemographic characteristics and other health-related variables.

RESULTS

Individuals with the highest cognitive limitation scores, without family visits, without supplementary health insurance, and with poor oral health status were less likely to consult a dentist. After controlling for potential selection bias, the only variable that remained statistically significant in the outcome equation was the oral health status: when individuals with poor health status had consulted at least once, they had a higher level of dental care expenditure.

CONCLUSIONS

Functional limitations were barriers to accessing dental care even in institutions for adult with disabilities. These barriers should be overcome because they may worsen their oral health status and well-being. Given the lack of literature on this specific topic, our results are important from a policy perspective. Health authorities should be alerted by these findings.

Seasonal influenza vaccine uptake among people with disabilities: A nationwide population study of disparities by type of disability and socioeconomic status in France

People with disabilities use various preventive health services less frequently than others, notably because of a lower socioeconomic status (SES). We examined variations of seasonal influenza vaccine uptake according to type/severity of disability and SES. We analyzed (in 2016) data from the 2008 French national cross-sectional survey on health and disability (n=12,396 adults living in the community and belonging to target groups for seasonal influenza vaccination). We defined seasonal influenza vaccine uptake during the 2007-2008 season by the self-reporting of a flu shot between September 2007 and March 2008. We built scores of mobility, cognitive, and sensory limitations, and an SES score based on education, occupation, and income. We performed bivariate analyses and then multiple log-binomial regressions. The prevalence of vaccine uptake was 23% in the 18-64 group and 63% in the ≥65 group. In bivariate analyses, it was higher among people in both age groups who had mobility and/or cognitive limitations and in the ≥65 group among those with sensory limitations. In the multiple regression analyses, only the presence of major mobility limitations in the18-64 group remained significant. The probability of vaccine uptake was higher in the highest SES category than in the lowest. Among at-risk groups, people with disabilities were more frequently vaccinated than others, mainly because of their higher levels of morbidity and healthcare use. Socioeconomic inequalities in access to vaccination persist in France. Future research is needed to monitor the trend in vaccine uptake in institutions.

Use of care and the oral health status of people aged 60 years and older in France: results from the National Health and Disability Survey

Objective

We aimed to analyze, from the data in a national survey, the use of oral care and the oral health status of patients living at home or in an institution.

Background

Patients aged 60 years and older have important oral health needs, but their oral management may differ according to their immediate environment. The fact of living at home or in an institution can influence the use of care and alter the patients’ perception of their oral health status.

Methods

The data analyzed were taken from a survey on disability and health carried out in 2008–2009, which is representative of the population living in France. It consists of two sections, one centered on disability and health among home-dwellers and the other on patients living in an institution. In each of these two populations, we carried out descriptive analysis of three themes: use of care, forgoing of care, and oral health.

Results

Although visits to physicians and specialists were frequent, visits to dentists were lower in both populations. While a minority of patients forwent care, it was dental care that was mainly forgone by both home-dwellers and institutionalized patients. The cost factor remained the principal reason, but other factors such as fear or accessibility problems were cited. Use of a dental appliance was considerably more frequent among institutionalized patients than among home-dwellers, with just over half the institutionalized population wearing a dental appliance. Perceived state of oral health remained difficult to interpret.

Conclusion

To improve access to oral care for the elderly, the patients, their entourage and health providers need increased awareness and information on the importance of good oral health. Better information must be associated with regular clinical examination.

Socioeconomic determinants of access to health services among older adults: a systematic review

OBJECTIVE

The objective of this study was to analyze the association between the socioeconomic characteristics and the access to or use of health services among older adults.

METHODS

This is a systematic review of the literature. The search has been carried out in the databases PubMed, LILACS and Web of Science, without restriction of dates and languages; however we have included only articles published in Portuguese, English, and Spanish. The inclusion criteria were: observational design, socioeconomic factors as variables of interest in the analysis of the access to or use of health services among older adults, representative sample of the target population, adjustment for confounding factors, and no selection bias.

RESULTS

We have found 5,096 articles after deleting duplicates and 36 of them have been selected for review after the process of reading and evaluating the inclusion criteria. Higher income and education have been associated with the use and access to medical appointments in developing countries and some developed countries. The same association has been observed in dental appointments in all countries. Most studies have shown no association between socioeconomic characteristics and the use of inpatient and emergency services. We have identified greater use of home visits in lower-income individuals, with the exception of the United States.

CONCLUSIONS

We have observed an unequal access to or use of health services in most countries, varying according to the type of service used. The expansion of the health care coverage is necessary to reduce this unequal access generated by social inequities.

The healthcare system and the provision of oral healthcare in EU Member States: France

The French oral health system is based on the provision of dental treatment and is organised around a fee-per-item model. The system is funded by a complex mix of public and complementary health insurance schemes. The system is successful in that it provides access to affordable dental treatment to the majority of the French population. However, France had the highest health expenditure as a share of gross domestic product (GDP) of all European Union countries in 2008 and rising oral health inequalities may be exacerbated by the manner in which oral health care is provided and funded. In addition, there is no organised national strategy for the prevention of oral diseases or for oral health promotion.

What Are the Determinants of Specialized Outpatient and Dental Care Use in Adults With Disabilities Living in Institutions: Findings From a National Survey in France

OBJECTIVE

To explore the determinants of specialized outpatient care use (general practitioners excluded) in people with disabilities living in institutions.

DESIGN

Cross-sectional study.

SETTING

National health and disability survey.

PARTICIPANTS

People (N=2528) living in institutions for adults with cognitive, sensory, and mobility disabilities.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

We used different measures of disability severity available in the survey: (1) the continuous score of limitations based on a measure we constructed according to self-reported level of difficulty performing 18 tasks without aid; (2) the Katz Index; and (3) the respondent's self-reported perception of functional limitations. Logistic regressions were performed to examine the determinants of the likelihood of having consulted a specialized outpatient care physician or a dentist at least once in the previous year.

RESULTS

Of the 2528 individuals, 45% (1141) and 28% (697) had respectively consulted a specialized outpatient care physician or a dentist at least once in the previous year. After adjusting for health care needs, higher functional limitation scores, dependency in all 6 activities of daily living, and self-reported perceptions of severe functional limitations were significantly associated with a lower likelihood of having consulted a specialized outpatient care physician (adjusted odds ratio [AOR], .95 [95% confidence interval {CI}, .94-.96]; AOR, .29 [95% CI, .23-.38]; and AOR, .51 [95% CI, .42-.62], respectively) or a dentist (AOR, .95 [95% CI, .94-.96]; AOR, .29 [95% CI, .21-.39]; AOR, .55 [95% CI, .44-.67], respectively) at least once in the previous year. Being a man, reporting a lack of family support, and having a low socioeconomic status also significantly affected specialized outpatient care use.

CONCLUSIONS

Regardless of the method used to define and measure disability, a high degree of disability negatively affects specialized outpatient care use after adjusting for health care need. Further studies are needed to better understand the reasons why this association between the degree of functional limitation and unmet medical needs is also a reality for people with disabilities living in institutions.

Community factors predicting dental care utilization among older adults

BACKGROUND

Few investigators have studied the influence of community factors on dental care utilization among older adults. The authors' objective in this study was to investigate the effect of community factors on dental care utilization after adjustment for individual factors.

METHODS

Using data from a cross-sectional survey of Ohio residents, the authors assessed dental care utilization in a sample of 2,166 adults 65 years or older. They linked individual-level dental care utilization, predisposing factors (age, sex, race or ethnicity, marital status, education), enabling factors (poverty, dental insurance) and need-related factors (physical and mental health problems) with county-level data (socioeconomic environment and health resource environment) from the 2010 Area Health Resource Files (from the U.S. Department of Health and Human Services) and the American Community Survey (from the 2006-2010 U.S. census). By using multilevel logistic regression models, the authors evaluated the association between dental care utilization and community factors after adjustment for individual factors.

RESULTS

The results indicated that individual factors such as being female, married and nonpoor and having a higher educational level and private dental insurance were associated with higher odds of having utilized dental care. Furthermore, older adults living in a county with a higher dentist-to-population ratio were more likely to use dental services even after the authors adjusted the results for the individual-level factors (odds ratio = 1.10; P = .03).

CONCLUSIONS

County-level dentist-to-population ratio has independent effects on older adults' dental care utilization even after adjustment for individual-level characteristics. Practical Implications. A comprehensive policy plan is required to intervene at both the individual and community levels to improve dental care utilization among older adults. By understanding the factors influencing dental care utilization among older adults, U.S. dentists will be better positioned to meet the dental needs of this population.

Individual- and community-level social gradients of edentulousness

Background

Community-level factors as well as individual-level factors affect individual health. To date, no studies have examined the association between community-level social gradient and edentulousness. The aim of this study was to investigate individual- and community-level social inequalities in edentulousness and to determine any explanatory factors in this association.

Methods

We analyzed the data from the Japan Gerontological Evaluation Study (JAGES). In 2010-2012, 112,123 subjects aged 65 or older responded to the questionnaire survey (response rate = 66.3%). Multilevel logistic regression analysis was applied to determine the association between community-level income and edentulousness after accounting for individual-level income and demographic covariates. Then, we estimated the probability of edentulousness by individual- and community-level incomes after adjusted for covariates.

Results

Of 79,563 valid participants, the prevalence of edentulousness among 39,550 men (49.7%) and 40,013 women (50.3%) were both 13.8%. Living in communities with higher mean incomes and having higher individual-level incomes were significantly associated with a lower risk of edentulousness (odds ratios [ORs] by 10,000 USD increments were 0.37 (95% confidence interval [CI] [0.22-0.63]) for community-level and 0.85 (95% CI [0.84-0.86]) for individual-level income). Individual- and community-level social factors, including density of dental clinics, partially explained the social gradients. However, in the fully adjusted model, both community- and individual-level social gradients of edentulousness remained significant (ORs = 0.43 (95% CI [0.27-0.67]) and 0.90 (95% CI [0.88-0.91]), respectively). One standard deviation changes in community- and individual-level incomes were associated with 0.78 and 0.84 times lower odds of edentulousness, respectively. In addition, compared to men, women living in communities with higher average incomes had a significantly lower risk of edentulousness (p-value for interaction < 0.001).

Conclusions

Individual- and community-level social inequalities in dental health were observed. Public health policies should account for social determinants of oral health when reducing oral health inequalities.

Social determinants of denture/bridge use: Japan gerontological evaluation study project cross-sectional study in older Japanese

Background

Studies suggest that using a denture/bridge may prevent disability in older people. However, not all older people with few remaining teeth use a denture/bridge. This cross-sectional study aimed to examine the social determinants which promote denture/bridge use among older Japanese.

Methods

A total of 54,388 (25,630 males and 28,758 females) community-dwelling individuals aged 65 or over, living independently, able to perform daily activities, and with 19 or fewer teeth. The dependent variable was denture/bridge use. Socio-demographics, number of teeth, present illness, social participation, social support, and social networks were used as individual-level independent variables. Data for social capital were aggregated and used as local district (n = 561 for males, n = 562 for females) -level independent variables. Number of dentists working in hospitals/clinics per population and population density were used as municipality (n = 28) -level independent variables. Three-level multilevel Poisson regression analysis was performed for each sex.

Results

High equivalent income, low number of teeth, present illness, and living in a municipality with high population density were significantly associated with denture/bridge use in both sexes in the fully adjusted models (p < 0.05). Denture/bridge use was significantly associated with high educational attainment in males and participating in social groups in females in the fully adjusted model (p < 0.05). No significant associations were observed between denture/bridge use and social capital.

Conclusions

Denture/bridge use was significantly associated with high economic status and present illness in both sexes, high educational attainment in males, and participation in social groups in females among community-dwelling older Japanese after adjusting for possible confounders.

Socioeconomic inequalities in the non-use of dental care in Europe

INTRODUCTION

Oral health is an important component of people's general health status. Many studies have shown that socioeconomic status is an important determinant of access to health services. In the present study, we explored the inequality and socioeconomic factors associated with people's non-use of dental care across Europe.

METHODS

We obtained data from the European Union Statistics on Income and Living Conditions survey conducted by Eurostat in 2007. These cross-sectional data were collected from people aged 16 years and older in 24 European countries, except those living in long-term care facilities. The variable of interest was the prevalence of non-use of dental care while needed. We used the direct method of standardisation by age and sex to eliminate confounders in the data. Socioeconomic inequalities in the non-use of dental care were measured through differences in prevalence, the relative concentration index (RCI), and the relative index of inequality (RII). We compared the results among countries and conducted standard and multilevel logistic regression analyses to examine the socioeconomic factors associated with the non-use of dental care while needed.

RESULTS

The results revealed significant socio-economic inequalities in the non-use of dental care across Europe, the magnitudes of which depended on the measure of inequality used. For example, inequalities in the prevalence of non-use among education levels according to the RCI ranged from 0.005 (in the United Kingdom) to -0.271 (Denmark) for men and from -0.009 (Poland) to 0.176 (Spain) for women, whereas the RII results ranged from 1.21 (Poland) to 11.50 (Slovakia) for men and from 1.62 (Poland) to 4.70 (Belgium) for women. Furthermore, the level-2 variance (random effects) was significantly different from zero, indicating the presence of heterogeneity in the probability of the non-use of needed dental care at the country level.

CONCLUSION

Overall, our study revealed considerable socioeconomic inequalities in the non-use of dental care at both the individual (intra-country) and collective (inter-country) levels. Therefore, to be most effective, policies to reduce this social inequality across Europe should address both levels.

A multi-country comparison of reasons for dental non-attendance

The purpose of this study was to describe differences across countries with respect to the reasons for dental non-attendance by Europeans currently 50 yr of age and older. The analyses were based on retrospective life-history data from the Survey of Health, Ageing, and Retirement in Europe and included information on various reasons why respondents from 13 European countries had never had regular dental visits in their lifetime. A series of logistic regression models was estimated to identify reasons for dental non-attendance across different welfare-state regimes. The highest proportion of respondents without any regular dental attendance throughout their lifetime was found for the Southern welfare-state regime, followed by the Eastern, the Bismarckian, and the Scandinavian welfare-state regimes. Factors such as patients' perception that regular dental treatment is 'not necessary' or 'not usual' appear to be the predominant reason for non-attendance in all welfare-state regimes. The health system-level factor 'no place to receive this type of care close to home' and the perception of regular dental treatment as 'not necessary' were more often referred to within the Southern, Eastern, and Bismarckian welfare-state regimes than in Scandinavia. This could be relevant information for health-care decision makers in order to prioritize interventions towards increasing rates of regular dental attendance.

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

AIM

To assess the socioeconomic-related inequality in dental care utilization among Thai elderly and to determine factors associated with the observed inequality after the country achieved universal coverage.

METHODS

The data were taken from the nationally representative Thailand Health & Welfare Survey 2007. Data of 10,096 Thai elderly (aged over 60 years) were selected. Descriptive analyses of the features of dental care utilization among Thai elderly were carried out, in addition to the concentration index (Cindex ) being used to quantify the extent of socioeconomic-related inequality in dental care utilization. Logistic regression was used to determine factors associated with inequality in dental care.

RESULTS

Socioeconomic-related inequality in dental care utilization among Thai elderly was shown. Also, utilization was more concentrated among wealthier older adults, as shown by the positive value of Cindex (equals 0.244). The poor elderly, however, were more likely to utilize dental care at public facilities, particularly primary care facilities. Multivariate analysis showed that certain demographic, socioeconomic and geographic characteristics were particularly associated with poor-rich differences in dental care utilization among Thai elderly.

CONCLUSIONS

Although socioeconomic-related inequality in dental care utilization among Thai elderly exists, the pro-poor utilization at public facilities, particularly primary care facilities, substantiates the concerted effort to reducing inequality in dental care utilization for Thai elderly.
