Dental status, visits, and functional ability and dietary intake of elderly in Israel

Analysis of factors associated with tooth loss in older adults from 1995 to 2015: a population-based cross-sectional survey in Guangdong, China

OBJECTIVES

The aim of this study was to detect trends and related factors in the functional dentition (FD) in 65- to 74-year-olds in Guangdong, China, while also assessing trends in education and income inequality factors.

MATERIALS AND METHODS

Three large-scale cross-sectional National Oral Health Surveys (NOHS), specifically NOHS II in 1995, NOHS III in 2005, and NOHS IV in 2015, were included. Post hoc stratification was weighted for 1038 participants aged 65 to 74years. Retaining teeth ≥ 20 teeth and retaining < 20 teeth was defined as functional dentition (FD) and nonfunctional dentition (NFD), respectively. Logistic regression models were established to assess related factors. Slope index of inequality (SII) and relative index of inequality (RII) were used to analyze inequality.

RESULTS

From NOHS II to IV, the FD proportion increased from 42.8 to 71.9%. Years of NOH, with caries, with periodontal pocket, high educational level, high income level, female, and those who had dental visits were associated with FD preservation. The education-related SII decreased from 0.44 to 0.20, and the income-related SII increased from 0.13 to 0.16.

CONCLUSIONS

The FD proportion among 65- to 74-year-olds improved from 1995 to 2015. Years of NOHS, with caries, with periodontal pocket, high education level, and high income level were associated with higher FD proportion. Female and those who had dental visits were associated lower FD proportion. Social inequalities in FD persisted, especially economic-related inequalities. Public health policy support and respective interventions should be applied to increase FD retention.

The Association of Oral Processing Factors and Nutrient Intake in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

CONTEXT

Oral health and food oral-processing issues emerge with functional decline in the older adult population, potentially increasing the risk of malnutrition. Impairment of oral health is associated with poorer nutrition status; however, the relationship between oral factors and the intake of each nutrient remains poorly understood.

OBJECTIVE

The associations between different oral factors and nutrient intakes among community-dwelling older adults were investigated.

DATA SOURCES

A literature search from 5 databases (Web of Science, Scopus, Cochrane Library, Ovid [MEDLINE and Embase], and CINAHL) was completed on February 1, 2022. The search was limited to peer-reviewed articles published between the years 2012 and 2022.

DATA EXTRACTION

Six cross-sectional studies were included in the meta-analysis. Two authors independently completed the data extraction and summarized the study characteristics, factors adjusted for in the statistical analysis, the outcome, and summary statistics of the results.

DATA ANALYSIS

Meta-analyses showed evidence of a significant association between compromised oral factors (namely, denture status, chewing ability, and the number of teeth) with lower energy (weighted mean difference [WMD], -107 kcal d-1 (95% CI, -132 to -81), protein (WMD, -5.2 g d-1; 95% CI, -6.6 to -3.8), fat (WMD, -4.6 g d-1; 95% CI, -6.7 to -2.6), carbohydrate (WMD, -8.8 g d-1; 95% CI, -13.9 to -3.7), and vitamin C intakes (WMD, -12.9 mg d-1; 95% CI, -16.6 to -9.2) in older adults.

CONCLUSION

Oral health can be an indicator of compromised daily energy, protein, fat, carbohydrate, and vitamin C intakes in older adults. However, the small sample size of the studies included in this review and the heterogeneity among macronutrient studies should be considered. Because of the lack of studies covering all aspects of food oral processing (eg, salivary flow rate, tongue pressure), the associations between oral processing and nutrient intake were not thoroughly explored.

Success factors and barriers in interprofessional collaboration between dental hygienists and dietitians in community-dwelling older people: Focus group interviews

INTRODUCTION

Poor nutritional status can impair oral health while poor oral health can influence the individual's dietary intake, which may result in malnutrition. This interaction between nutritional status and oral health in older age requires attention, coordination and collaboration between healthcare professionals. This qualitative study explores dental hygienists' and dietitians' opinions about current collaboration with the aim of identifying success factors and barriers to this interprofessional collaboration.

METHODS

Three focus group interviews were held with Dutch dental hygienists and dietitians about nutritional and oral healthcare in community-dwelling older people.

RESULTS

In total, 9 dietitians and 11 dental hygienists participated in three online focus group interviews. Dental hygienists and dietitians seldom collaborated or consulted with each other. They struggled with the professional boundaries of their field of expertise and experienced limited knowledge about the scope of practice of the other profession, resulting in conflicting information to patients about nutrition and oral health. Interprofessional education was scarce during their professional training. Organizational and network obstacles to collaborate were recognized, such as limitations in time, reimbursement and their professional network that often does not include a dietitian or dental hygienist.

CONCLUSION

Dental hygienists and dietitians do not collaborate or consult each other about (mal)nutrition or oral health in community-dwelling older people. To establish interprofessional collaboration, they need to gain knowledge and skills about nutrition and oral health to effectively recognize problems in nutritional status and oral health. Interprofessional education for healthcare professionals is needed to stimulate interprofessional collaboration to improve care for older people.

Uptake of dental hygienist services by the Israeli 65+ age group

OBJECTIVES

To learn about the use patterns of dental hygienist services, by the 65+ age group in Israel and to identify the main barriers facing different population groups.

METHODS

Telephone interviews with a representative sample of 512 older adults aged 65 and over were conducted from February to April 2020.

RESULTS

About 50% of the older adults aged 65 and over visited a dentist (2.9 visits on average) and 35% visited a dental hygienist in the year preceding the interviews. 17% reported never visiting a dentist and 45% never received care from a dental hygienist. Dental care use rates are lower in the outlying areas of the country, among non-Jews and among those who find it difficult to cover monthly household expenses. Those who regularly visit a dental hygienist maintain a preventive oral health routine, including tooth brushing and visits to the dentist for periodic preventive check-ups. They are aware of the harmful effects of eating sweets in between meals. Most of the older adults aged 65 and over are unaware of the reform under which hygienist' care was included in the basket of services provided by health plans.

CONCLUSIONS

There is underutilization of dental hygienist services and lack of awareness of proper oral health behaviour in the lower socioeconomic group. As less than 50% of older adults are aware of the legal rights for dental care, there is a need to raise awareness of the reform and the services provided under it.

Chewing ability and associated factors in older adults in Germany. Results from GEDA 2019/2020-EHIS

BACKGROUND

Oral well-being is an important component of general well-being and quality of life, as it is greatly influenced by the ability to chew and speak, and thus by central factors of social interaction. Because quality of life and participation are important factors for health in older age, the aim of this article was to examine the chewing ability, including associated factors, for the older population in Germany on the basis of a nationally representative sample.

METHODS

Database is the German Health Update (GEDA 2019/2020-EHIS), a population based cross-sectional survey of the Robert Koch Institute. In the telephone interview, participants aged 55 years and older were asked: "Do you have difficulty biting and chewing on hard foods such as a firm apple? Would you say 'no difficulty', 'some difficulty', 'a lot of difficulty' or 'cannot do at all/ unable to do'?" Prevalences and multivariate prevalence ratios (PR) were calculated with 95% confidence intervals (95% CI) from log-Poisson regressions. Sociodemographic, health-, behavioral- and care-related characteristics were investigated as associated factors.

RESULTS

The analyses were based on data from 12,944 participants (7,079 women, 5,865 men). The proportion of people with reduced chewing ability was 20.0%; 14.5% had minor difficulty, 5.5% had major difficulty. There were no differences between women and men. The most important associated factors for reduced chewing ability were old age (PR 1.8, 95% CI 1.5-2.1), low socioeconomic status (PR 2.0, 95% CI 1.7-2.5), limitations to usual activities due to health problems (PR 1.9, 1.6-2.2), depressive symptoms (PR 1.7, 1.5-2.1), daily smoking (PR 1.6, 95% CI 1.3-1.8), low dental utilization (PR 1.6, 95% CI 1.4-1.9), and perceived unmet needs for dental care (PR 1.7, 95% CI 1.5-2.1).

CONCLUSIONS

One fifth of adults from 55 years of age reported reduced chewing ability. Thus, this is a very common functional limitation in older age. Reduced chewing ability was associated with almost all investigated characteristics. Therefore, its prevention requires a holistic view in the living environment and health care context of older people. Given that chewing ability influences quality of life and social participation, maintaining or improving chewing ability is important for healthy aging.

What Is the Relationship between the Chewing Ability and Nutritional Status of the Elderly in Korea?

This study aims to determine the relationship between chewing ability and the nutritional status of the elderly in Korea. This study utilized the data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted from 2013-2018 for persons who were ≥65 years of age. Of the 7835 subjects, 43.2% had chewing difficulty. Compared to the normal group, the chewing difficulty group had more stress, lower exercise frequency, less snack intake, a lower frequency of eating out, and a higher proportion of food insecurity. The chewing difficulty group had significantly lower food intake compared to the normal group, including various food groups such as cereals and grain, potatoes, fruits, meat, and milks and dairy products. The intake of fresh fruits was 24.5% lower and the intake of plant food (fresh fruits and nonstarchy vegetables) was 17.8% lower in the chewing difficulty group compared to the normal group. In addition, the intake of most nutrients (carbohydrates, fat, calcium, phosphorus, sodium, potassium, vitamin A, riboflavin, niacin, and vitamin C) was significantly lower in the chewing difficulty group than in the normal group. The chewing difficulty was significantly associated with undernutrition (OR = 1.63). In conclusion, chewing ability is closely related to food and nutrient intake among the elderly, which can decrease the quantity and quality of diet and is also related to undernutrition. Therefore, it is necessary to develop customized nutrition programs and aging-friendly food products that consider the chewing ability of the elderly.

Malnutrition is associated with increased disease risk in older people in the Makkah region of Saudi Arabia: A cross-sectional study

Introduction

There is little research on the nutritional status of older people in Saudi Arabia. This study investigated the factors associated with the nutritional status of older people in the Makkah region, Saudi Arabia. We hypothesized that older people who are at risk of malnutrition are at higher risk of different diseases.

Materials and methods

This cross-sectional study surveyed 271 people aged ≥60 years from October 2021 to January 2022. We collected data on demographics, body mass index, the Geriatric Depression Scale-Short Form, Geriatric Oral Health Assessment Index, Mini Nutritional Assessment, Eating Attitudes Test, and Household Dietary Diversity score.

Results

Among the 271 participants, 13.3% were malnourished and 53.9% were at risk of malnutrition. The oral health (P &lt; 0.001), depression (P &lt; 0.001), and eating disorder (P &lt; 0.002) scores were significantly associated with malnutrition. Congestive heart failure, asthma, peripheral vascular disease, Alzheimer's disease, and hypertension were more prevalent among malnourished participants—this supports our original hypothesis. The HDD score showed no significant differences between men and women.

Conclusion

Malnutrition was associated with overweight or obesity, poor oral health, and depression. Older people in the Makkah region, Saudi Arabia, had a high risk of malnutrition.

Tooth retention, health, and quality of life in older adults: a scoping review

OBJECTIVE

This scoping review describes the relationship between tooth retention, health, and quality of life in older adults.

METHODS

Seven databases were searched for English language articles for subjects ≥ 65 y from 1981 to 2021. Exposure was tooth retention (≥ 20), and outcomes were general/systemic health and quality of life. Methodological quality was assessed using the Newcastle-Ottawa Scale and Cochrane Risk of Bias 2.0 tool.

RESULTS

140 articles were included, only four were randomized trials. Inter-rater agreement (κ) regarding study inclusion was 0.924. Most were assessed with low risk of bias (n = 103) and of good quality (n = 96). Most studies were conducted in Japan (n = 60) and Europe (n = 51) and only nine in the US. Tooth retention was referred to as "functional dentition" in 132 studies and "shortened dental arch" in 19 studies. Study outcomes were broadly synthesized as (1) cognitive decline/functional dependence, (2) health status/chronic diseases, (3) nutrition, and (4) quality of life.

DISCUSSION

There is a positive relationship between tooth retention, overall health, and quality of life. Older adults retaining ≥ 20 teeth are less likely to experience poorer health. Having < 20 teeth increases the likelihood for functional dependence and onset of disability, and may affect successful ageing. This review supports the general finding that the more teeth older adults retain as they age, the less likely they are to have adverse health outcomes. However, significant knowledge gaps remain which can limit decision-making affecting successful ageing for many older adults. This review highlights the need to consider, as an important marker of oral health and function, the retention of a functional minimum of a natural dentition, rather than a simple numeric score of missing teeth.

Oral Health among Adult Residents in Vilnius, Lithuania

According to the World Health Organization (WHO) oral conditions may be determined by social, biological, behavioral, and psychosocial factors. The study assessed oral health status and its determinants associated with oral health conditions among adult residents in Vilnius, Lithuania. A total of 453 of 35–74-year-olds participated (response rate 63%). A self-reported questionnaire was administered. Dental caries experience (D₃MFS score), periodontal probing depth (PPD), andnumber of missing teeth were assessed clinically. Data were analyzed using χ² test, independent samples t-test, and multivariable linear regression. The mean (sd) of D₃MFS scores was 67.3 (33.5), the mean (sd) number of teeth with PPD 4+ mm was 5.9 (5.3), prevalence of periodontitis was 33%, the mean (sd) number of missing teeth was 6.9 (6.8), and prevalence of total edentulism was 3.8%. Medication use was associated with all oral health conditions, while age was associated with caries experience, and missing teeth. Sugar-containing diet was associated with caries experience, and missing teeth, and smoking with caries experience and periodontal status. Systemic diseases were associated with periodontal status, while behavioral determinants, last dental visit, and use of fluoridated toothpaste were associated with missing teeth. Oral health status among adult Vilnius residents was poor. Oral conditions were associated with both biological and behavioral determinants. Oral health promotion should focus on modifying behavioral determinants.

The association of oral function with dietary intake and nutritional status among older adults: Latest evidence from epidemiological studies

Inadequate and poor quality of diet and malnutrition are common and associated with adverse health outcomes, including morbidity and mortality, among older persons. This review aimed to establish the latest evidence from studies investigating the association between oral function and nutrition among older adults. An electronic search of MEDLINE using PubMed for literature published in English between March 2018 and March 2021 was conducted, and 27 papers were identified. The selected studies comprised 23 observational studies (17 cross-sectional and 6 longitudinal studies) and 4 interventional studies. Most of the observational studies demonstrated the following associations in older adults: older adults with poor oral function are likely to have poorer dietary intake and poorer nutritional status, and malnourished older adults are likely to have poorer oral function. The results of the intervention studies demonstrated that the combination of prosthodontic treatment and dietary counseling is more effective for improving dietary intake and nutritional status in older persons with tooth loss than the prosthodontic treatment alone. Our review confirmed that a relationship exists between oral function and nutrition and revealed the need for additional high-quality studies investigating comprehensive oral function, rather than a single aspect of oral function, with regard to nutritional status.

Oral health of the 65+ age group in Israel-2020

Background

In 2019, a reform of dental services for older adults was implemented in Israel to improve access and reduce barriers that stood in their way. The reform stipulated that preventive and restorative dentistry would be included in the basket of services of the National Health Insurance Law. The current study was conducted by the Myers-JDC-Brookdale Institute (MJB) and the Division of Dental Health of Israel’s Ministry of Health to examine the dental status and patterns of utilizations of dental services among the 65+ age group. This paper reports on the dental status of the 65+ age group in comparison with the same population two decades earlier.

Goals

To describe the dental status of Israel’s 65+ age group, and to identify the population at risk of dental morbidity.

Methodology

Telephone interviews were conducted with a representative sample of 512 older adults aged 65+, from February to April 2020.

Main findings

Some two-thirds of the 65+ age group assessed their oral health as good or very good. Twenty-four percent did not have natural teeth, while the rest had 19 teeth on average. Ten percent had not lost any teeth. In the 65–74 age group, 19% had no natural teeth and the rest had 20 teeth on average. In contrast, in the 85+ age group, 38% were edentulous and the rest had 13 teeth on average. Of the older adults who found it difficult to cover their monthly expenses, 39% were edentulous—twice the percentage of those who did manage to cover their monthly expenses (19%). Of the 65+ age group 44% had dentures—37% in the 65–74 age group, and 66% in the 85+ age group. Approximately 40% of the 65+ age group saw a dentist for preventive check-ups. The rest did not, mainly due to lack of awareness of the importance of doing so.

Conclusions and recommendations

The perceived status of oral health among the 65+ age group is currently better than it was 22 years ago. However, despite the improvement in oral health and health behavior, there are still barriers to the utilization of dental services. The main barriers are a lack of awareness of the importance of proper health behavior, and the cost of care for people with financial difficulty. This study provides decision-makers with data on the status of oral health, the utilization of dental services and the geographical disparities. The findings will help policy makers evaluate the effectiveness of the reform and fine tuning it in the future. Policies should be instated to increase awareness of constituencies and their access to the services, in addition to the entitlements the reform granted.

Factors associated with utilisation of dental services by the elders from São Paulo, Brazil

BACKGROUND

Population ageing in Brazil is rapid and is likely to place additional pressure over the Brazilian public health system.

OBJECTIVE

This study aims to examine the factors associated with utilisation of dental services in the previous year among a representative sample of older adults from São Paulo, Brazil.

METHODS

The sample included 5951 older adults who participated in the SBSP-15 study, an epidemiological survey conducted in 2015 in the State of São Paulo, Brazil. The outcome "utilisation of dental services" was defined as having visited a dentist in the previous year. Chi-square tests were employed in the bivariate analyses and Poisson regressions with robust variance in the multilevel analysis.

RESULTS

Only 30.5% of the participants had their last dental appointment within the previous year. Number of teeth and dental pain presented the strongest effects on the investigated outcome. Education, income, age, ethnicity, living alone, higher Family Health Strategy coverage and the Metropolitan area were associated with having visited a dentist in the previous year. Older adults who rated their oral health as positive did not report treatment need nor prosthodontic need, presented negative oral health-related quality of life, had their last dental appointment in the public health system and sought treatment due to pain or extraction also were more likely to report the utilisation of dental services in the previous year.

CONCLUSION

Regional, sociodemographic and subjective factors are associated with utilisation of dental services in the previous year among the elders from the State of São Paulo, Brazil.

Factors affecting oral examinations and dental treatments among older adults in Israel

Background

Routine dental examinations are important for early diagnosis and treatment of dental problems among older adults in order to improve their quality of life and avoid costly future treatments. In Israel, a significant percentage of adults do not seek dental care.

Methods

The study is based on a 2017 telephone survey conducted among people aged 50–75 from different population groups in Israel to examine their health beliefs and attitudes toward dental treatments.

Results

The results show that among older adults the decision to undergo routine dental checkups is affected by socio-demographic status and health beliefs regarding dental health. Lower age, higher income levels, and Jewish religion predicted higher chances of frequent checkups. In addition, those who saw the benefits of routine checkups, believed that dentists were readily available, and had higher levels of health motivation were more likely to seek out routine dental care.

Conclusions

According to the recent dental reform in Israel, people aged 75 and over are eligible for subsidized dental treatments. To enhance the frequency of dental checkups among older adults, it is recommended to provide this subsidized coverage for adults under age 75. In addition, planning dental health services for individuals in this age group should be based upon their accepted beliefs and values. Moreover, systematic health education through the media and health maintenance organizations should specifically target this population group to encourage them to undergo dental checkups more frequently.

Prevention, prevention and prevention

A recent study by Levy et al. presents the dental treatment needs of a large sample of combat soldiers. They found that 80% need some dental care.

It is unfortunate that so many, educated, otherwise healthy young adults are in need of dental care and it indicates that more prevention of dental disease is needed.

In last years, the Ministry of Health started two projects to prevent dental disease among the very young: In Mother and Child Health Centers and in kindergartens. In a couple of years, these projects will be widely implemented. With the School Dental Service, these two projects will cover all ages from birth to 18.

In the future, with these programs implemented, soldiers should need less dental treatment.

Is the oral health reform in Israel optimally distributed? - A commentary

A traditional and ethical principle recognizes a country’s primary general welfare responsibility to the young and the old. However, the middle, adult, age group cannot and should not be disregarded. The current dental component of the National Health Insurance Law (NHIL), in Israel, only includes children and the elderly. The present commentary focuses on the large group of adults, age 19–74, which are currently excluded.

The cumulative incidence of disease increases over the lifetime of a person. We believe that a NHIL commitment with a major age gap in coverage is unacceptable. The recent manuscript, published by Natapov et al., in this journal, has documented the overall dental health of the older Israeli population, with emphasis on nutritional aspects. This contribution to the literature is commendable. However, we aim to follow in the steps of the Alma Ata Declaration and Ottawa Charter of the World Health Organization (WHO) and to clarify that the government’s responsibility should cover all residents regardless of their age. In addition, a dental health epidemiological data base, currently nonexistent for adults, is called for.
