Income-related inequalities in denture-wearing by Europeans aged 50 and above

Baby boomers in Europe: demography, socioeconomic, and health status and oral health needs

The European countries are aging fast. Baby boomers in Europe constitute a diverse population group with several differences in life events and living conditions. The fiscal effects of the aging of European population have led to changes in policies and legislation that largely affect the lives of baby boomers necessitating an increase in their working lives. Furthermore, reforms are planned in the existing health and long-term care systems. Although some baby boomers in Europe face chronic medical conditions, the majority perceive their general health as good or very good. However, approximately one quarter have reported unmet needs for medical care, mainly due to cost or long waiting lists with large variability among different countries. The oral health of baby boomers has improved compared to previous generations particularly related to tooth loss. However, older groups in many countries face an increase in dental caries and periodontal disease. Some baby boomers may enter very old age with many natural teeth, functional impairment, limited ability to perform oral hygiene and an increased demand for more complex dental care as well as domiciliary care. However, in contrast to medical care, dental expenses in Europe are mainly financed with out-of-pocket payments while domiciliary dental care is rarely provided leading to unmet dental care needs for the most vulnerable individuals. Educational interventions for all healthcare professionals, as well as formal and informal carers and the public are required, and appropriate policies and legislations are needed to promote the oral health of the aging European population.

Difference of income inequalities of denture use by co-payment rates: A JAGES cross-sectional study

OBJECTIVES

Studies suggest that wearing dentures to restore missing teeth can have a positive impact on health status. However, income inequalities in denture wearing exist. The aim of this study was to investigate how differing co-payment rates under the current Japanese Universal Health Insurance Coverage System affect income inequalities in denture non-use among older adults with severe tooth loss.

METHODS

This cross-sectional study used data from the 2019 Japan Gerontological Evaluation Study (JAGES). Self-administered questionnaires were mailed to 345 356 independent people who did not receive long-term care insurance benefits and were aged ≥65 years. The dependent variable was denture non-use, and the independent variable was the equivalent annual household income. The Slope Index of Inequality (SII) and Relative Index of Inequality (RII) were used with regression-based approaches to determine both absolute and relative inequalities in denture non-use by co-payment rates. The covariates were sex, age, years of education, number of teeth and comorbidities.

RESULTS

Of the 240 889 responses received (response rate =69.9%), we analysed 21 594 participants who fulfilled the inclusion criteria. The mean age was 72.8 years (standard deviation =4.1), and 57.6% were men. For 30 per cent, 20 per cent and 10 per cent co-payment rates, the percentages of people who did not use dentures and had severe tooth loss (≤9 teeth) were 18.3%, 13.3%, and 8.5%, respectively. All analyses confirmed significant inequalities in denture non-use. The lower the co-payment rate, the smaller the inequalities. SIIs for each co-payment rate were as follows: 30 per cent =13.35% (95% confidence interval [CI] = 9.61-17.09); 20 per cent =7.85% (95% CI = 4.88-10.81); and 10 per cent =4.85% (95% CI = 2.55-7.16). Inclusion of interaction term between income and co-payment rate significantly lowered the inequalities by co-payment rate in logistic regression analysis and SII. For RII, although the interaction was not statistically significant, a similar trend was observed.

CONCLUSIONS

Income inequalities in denture use existed among older adults with severe tooth loss in Japan, and the inequalities appeared to be greater when the co-payment rate was higher.

Do health systems cover the mouth? Comparing dental care coverage for older adults in eight jurisdictions

Oral health is an important component of general health, yet there is limited financial protection for the costs of oral health care in many countries. This study compares public dental care coverage in a selection of jurisdictions: Australia (New South Wales), Canada (Alberta), England, France, Germany, Italy, Sweden, and the United States. Drawing on the WHO Universal Coverage Cube, we compare breadth (who is covered), depth (share of total costs covered), and scope (services covered), with a focus on adults aged 65 and older. We worked with local experts to populate templates to provide detailed and comparable descriptions of dental care coverage in their jurisdictions. Overall most jurisdictions offer public dental coverage for basic services (exams, x-rays, simple fillings) within four general types of coverage models: 1) deep public coverage for a subset of the older adult population based on strict eligibility criteria: Canada (Alberta), Australia (New South Wales) and Italy; 2) universal but shallow coverage of the older adult population: England, France, Sweden; 3) universal, and predominantly deep coverage for older adults: Germany; and 4) shallow coverage available only to some subgroups of older adults in the United States. Due to the limited availability of comparable data within and across jurisdictions, further research would benefit from standardized data collection initiatives for oral health measures.

Income-related health inequalities among the migrant and native-born populations in Greece during the economic crisis: a decomposition analysis

Background

The economic crisis has induced detrimental socio-economic and health effects in Greece. This study aims to measure overall income-related health inequalities and examine their determinants, and to compare the respective within estimates for major subpopulations defined by citizenship (Greece, Albania, other countries) in Greece.

Methods

Data for 1332 cases were collected from a cross-sectional observational survey (MIGHEAL) conducted at a national level in 2016. Income-related inequalities in poor subjective health, limiting long-standing illness, elevated depressive symptoms and non-communicable diseases were measured with the standard and Erreygers concentration indices. Decomposition analysis identified key factors explaining the inequalities.

Results

Overall, significant inequalities favouring the better-off were established in all ill-health indicators, particularly in depression. Greek citizens were associated with consistent health inequalities, while, concerning the other groups, significant disparities were found only in depression for Albanians. Decomposition analyses identified socio-economic status, income in particular, as the main contributor to overall income-related health inequalities, followed by barriers to healthcare access, adverse family background and hazardous working conditions. Risk behaviours and discrimination were relatively less important, whereas area of residence was mainly reducing inequality. Citizens from Albania and other countries were found to be poorer, but with fewer health problems, hence, different citizenship decreased inequalities.

Conclusion

Socio-economic health inequalities in Greece can be mitigated by means of appropriate multi-sectorial policy interventions, by focussing primarily on the most socio-economically disadvantaged groups. The overall inequality-producing mechanisms and the different health needs of ethnic groups should be taken into account when formulating such policies.

Experience of dental care, knowledge and attitudes of older immigrants in Sweden-A qualitative study

OBJECTIVES

Knowledge about the oral health and dental care habits of older immigrants is limited. The aim of this study was to explore dental service utilization, oral care habits, and attitudes to and knowledge about oral diseases and their prevention among older immigrants in Sweden.

METHODS

A qualitative research method was used, and data were collected in individual interviews to gain a deeper understanding of the immigrants' views. Thirteen immigrants, seven women and six men, recruited from meeting places for older immigrants, participated, all aged between 59 and 88 (median 72 years). Interviews were tape-recorded and transcribed verbatim. Eight interviews were carried out with the help of an authorized interpreter.

RESULTS

In the analytical process, performed using the content analysis method, meaning units were identified and condensed into codes which were labelled and grouped into subcategories and categories. The interview analysis resulted in four categories: Experiences of dental care, Attitudes, Barriers and Prevention of oral diseases. The elderly immigrants described a mix of regular and acute dental care and were often not satisfied with the outcome of the treatments. They stated that oral health was important and that they were responsible for their own teeth. Barriers to dental care were costs, language problems and lack of confidence in dental services. Daily oral hygiene routines were performed using a traditional chewing stick and/or regular toothbrush.

CONCLUSION

The participants stated that, despite the barriers to treatment described above, they valued good oral health and visited dental services when they needed to.

Midlife Cognitive Ability, Education, and Tooth Loss in Older Danes

OBJECTIVE

To examine the possible influence of cognitive ability and education at age 50 or 60 on number of teeth at age 70.

SETTING

Community-dwelling population in Copenhagen, Denmark.

PARTICIPANTS

Men and women born in 1914 (N = 302).

MEASUREMENTS

Cognitive ability was assessed using the Wechsler Adult Intelligence Scale at age 50 or 60. A global cognitive ability measure was used as a continuous measure and according to tertile. Information on education was gathered using a questionnaire at age 50 or 60. A clinical oral examination took place at age 70, and oral health was measured according to number of teeth (<6 vs ≥6). Baseline covariates were smoking, alcohol, sex, and income.

RESULTS

Logistic regression analyses revealed that greater cognitive ability and educational attainment had a protective effect against risk of tooth loss. The associations were significant and persisted after adjusting for confounders and a two-way interaction between cognitive ability and education.

CONCLUSION

Higher education level and cognitive ability measured at age 50 or 60 were associated with having more teeth at age 70. Whether these findings are due to the interaction of these factors with oral health, related socioeconomic factors, or other factors remains to be studied.

Oral health status in older immigrants in a medium-sized Swedish city

AIM

The aim of the study was to investigate oral health and oral care habits among older immigrants to Sweden from countries outside the Nordic region.

METHOD

Participants ≥60 years of age from senior social centers for immigrants were invited to attend oral examinations. Data was collected on the number of teeth, dentures, caries, periodontal status, saliva secretion, and plaque scores. Participants also described their general health and oral care habits.

RESULTS

Fourteen men and 28 women, median age 71.5 years, participated. Seventeen percent were edentulous, women often than men. Three out of four had caries and 63% had gingival bleeding. Two-thirds brushed their teeth twice per day and 60% had visited dental services in the last 2 years.

CONCLUSION

The group had a high prevalence of oral diseases and discomfort. They used dental services and brushed their teeth less frequently than Swedish populations of the same age.

Explaining inequalities in Health Care Utilization among Turkish adults: Findings from Health Survey 2008

BACKGROUND

Turkish health system showed major improvements in health outcomes since initiation of the Health Transition Programme (HTP) in 2003, however little is known regarding income-related inequalities in health care use. The aim of this study was to assess horizontal inequities in health care use in Turkey.

METHODS

We used the data from Turkish Health Survey 2008 with 14,655 respondents. We calculated concentration index (C) and horizontal inequity index (HI) to measure the socioeconomic inequalities in utilization of general practitioner (GP) care, specialist care, inpatient care, dental care and emergency care. Contributions of each factor to the observed inequality in health care utilization were assessed through decomposition method.

RESULTS

There was a significant pro-rich inequality in specialist care and oral health care utilization among individuals as indicated by positive values of HI (=0.1149) and HI (=0.1137), respectively. However, the poor were more likely to utilize emergency care (HI=-0.0461) and inpatient care (HI=-0.0731). GP care was also slightly pro-poor distributed (HI=-0.0042).

CONCLUSION

Pro-poor income-related inequalities in health care use were largely explained by greater health care need among low income groups, while non-need factors were the main determinants for pro-rich utilization (education, residence area). Inequalities in dental and specialist care linked to low income, low education level and rural areas should be given priority by decision makers to reduce the negative impact of utilization on health. Our results provide some evidence of inequity in 2008, after the introduction of HTP and provide a baseline against which the effects of the new reforms can be assessed.

Dental health among older Israeli adults: is this a reflection of a medical care model inadequately addressing oral health?

OBJECTIVES

Israel's health-care system is considered as one of the most efficient worldwide. The purpose of the present study was to assess oral health outcomes, dental care use and respective social inequalities among the older segment of the Israeli population.

METHODS

Secondary analyses were conducted of recently available data from the Survey of Health, Ageing, and Retirement in Europe (SHARE Israel, wave 2), which specifically includes information on chewing ability, denture wearing and dental care use obtained from more than 2,400 Israeli people, 50+ years of age. Multivariate logistic regressions and concentration indices were used to analyse determinants of oral health and dental care use.

RESULTS

Seventy per cent of respondents reported being able to bite/chew on hard foods and 49% of respondents reported wearing dentures. Forty-three per cent of respondents had visited a dentist within the past 12 months, with about half of all dental visits being made for solely nonpreventive reasons. Significant income-related inequalities were identified, with higher income being associated with greater dental care use (particularly preventive dental visits), better chewing ability and less denture wearing.

CONCLUSIONS

For the older segment of the Israeli population and compared with other countries, the findings of the present study suggest a relatively low level of chewing ability, a high extent of nonpreventive dental visiting, as well as considerable inequalities in oral health and care. It seems that the Israeli health-care system may be improved even further by more comprehensive inclusion of dental care into universal health coverage.

Forgoing dental care for economic reasons in Switzerland: a six-year cross-sectional population-based study

Background

While oral health is part of general health and well-being, oral health disparities nevertheless persist. Potential mechanisms include socioeconomic factors that may influence access to dental care in the absence of universal dental care insurance coverage. We investigated the evolution, prevalence and determinants (including socioeconomic) of forgoing of dental care for economic reasons in a Swiss region, over the course of six years.

Methods

Repeated population-based surveys (2007–2012) of a representative sample of the adult population of the Canton of Geneva, Switzerland. Forgone dental care, socioeconomic and insurance status, marital status, and presence of dependent children were assessed using standardized methods.

Results

A total of 4313 subjects were included, 10.6% (457/4313) of whom reported having forgone dental care for economic reasons in the previous 12 months. The crude percentage varied from 2.4% in the wealthiest group (monthly income ≥13,000CHF, 1CHF ≈ 1$) to 23.5% among participants with the lowest income (<3,000CHF). Since 2007/8, forgoing dental care remained stable overall, but in subjects with a monthly income of <3,000CHF, the adjusted percentage increased from 16.3% in 2007/8 to 20.6% in 2012 (P trend = 0.002). Forgoing dental care for economic reasons was independently associated with lower income, younger age, female gender, current smoking, having dependent children, divorced status and not living with a partner, not having a supplementary health insurance, and receipt of a health insurance premium cost-subsidy.

Conclusions

In a Swiss region without universal dental care insurance coverage, prevalence of forgoing dental care for economic reasons was high and highly dependent on income. Efforts should be made to prevent high-risk populations from forgoing dental care.

Oral health conditions and cognitive functioning in middle and later adulthood

Background

The purpose of the present study was to examine the impact of oral health conditions on cognitive functioning on basis of data samples from several European countries.

Methods

Secondary analyses were conducted of data from wave 2 of the Survey of Health, Ageing, and Retirement in Europe (SHARE) which includes 14 European countries and is intended to be representative of each country’s middle and later adulthood population. Information on word recall, verbal fluency, and numeracy as well as information on chewing ability and denture wearing status was available for a total of 28,693 persons aged 50+. Multivariate regression analysis was used to detect influences of oral health parameters on cognitive functioning (p < 0.05).

Results

Persons with good chewing ability or without dentures had significantly better word recall, verbal fluency, and numeracy skills than persons with chewing impairment or with dentures. The observed patterns of parameter estimates imply differential oral health impacts on numeracy compared to word recall and verbal fluency.

Conclusions

The present study provides novel large-scale epidemiological evidence supportive of an association between oral health and cognitive functioning. Future research should intend to verify the precise causal links between oral health conditions, various cognitive dimensions, and their neural correlates.

Measuring socio-economic inequalities in edentate Scottish adults--cross-sectional analyses using Scottish Health Surveys 1995-2008/09

OBJECTIVES

To investigate the appropriateness of different measures of socio-economic inequalities, in relation to adult oral health in Scotland, utilizing data from a series of large, representative population surveys.

METHODS

The Scottish Health Surveys (SHeS) (1995; 1998; 2003; 2008/09) are cross-sectional national population-based surveys used to monitor health status in those living in private households. The age groups included in this study are as follows: 45-54; 55-64 years: all survey years; 65-74: 1998 onwards; 75+: 2003 onwards. Primary outcome was no natural teeth (edentulism). Three measures of socio-economic position: Occupational social class, Education, Carstairs deprivation score (2001) were used. Simple (absolute/relative differences) and complex measures (Slope Index, Relative Index, Concentration Index and c-index) of inequality were produced for each age group across all four surveys.

RESULTS

Simple and complex (absolute) measures of inequality have both demonstrated narrowing disparities in edentulism over time in the 45- to 64-year-old group, a levelling off in those aged 65 and above, and a rise in those aged 75+. Complex relative measures (RII, Concentration Index and c-index), however, show an increasing trend in inequalities over time for all age groups, suggesting that rates of improvement in edentulism rates are not uniform across all social groups.

CONCLUSIONS

Simple absolute inequality provides a quick and easy indication of the extent of disparities between extreme groups, whereas complex measures (absolute and relative) consider the gradient in health across all social groups. We have demonstrated that both are useful measures of inequality and should be considered complementary to one another. The appropriate choice of complex measure of inequality will depend on the audience to whom the results are to be communicated. This methodological approach is not confined to oral health but is applicable to other health outcomes that are socially patterned.
