Contextual and individual factors associated with public dental services utilisation in Brazil: A multilevel analysis

Using Andersen's behavioural model to examine individual and contextual factors associated with dental service utilization in Brazil

OBJECTIVES

The study aimed to examine individual and contextual factors associated with the frequency of dental service utilization among adolescents, adults and older adults Brazilians.

METHODS

This cross-sectional study used secondary data from the Brazilian 2019 National Health Survey (94 114 individuals). The outcome 'when was your last dental appointment?' was categorized into three groups: up to 1 year, more than 1 year and never had a dental appointment. Andersen's behavioural model was used to select contextual and individual variables. Multinomial logistic regression analysis was performed to calculate the odds ratio (OR) and 95% confidence intervals (95% CI).

RESULTS

The following variables showed increased probability to the outcome had the last dental appointment more than 1 year ago: older adult, illiterate or incomplete primary school, and without private dental insurance. The outcome never had a dental appointment was significantly associated with illiterate (OR 26.65; 95% CI 17.63-40.29), male (OR 2.38; 95% CI 2.17-2.61), without private dental insurance (OR 5.20; 95% CI 3.48-7.76), self-rated oral health as bad or very bad (OR 2.67; 95% CI 2.31-3.09), household not enrolled in primary care teams (OR 1.29; 95% CI 1.11-1.49), household in a rural area (OR 1.86; 95% CI 1.69-2.05), high household crowding (OR 1.08; 95% CI 1.04-1.14) and low household income per capita (OR 0.99; 95% CI 0.99-0.99).

CONCLUSIONS

This study showed that contextual and individual factors induce inequity in dental appointments. Moreover, Andersen's behavioural model demonstrated inequitable access for dental services in Brazil, in which social structure and enabling characteristics, rather than the need for the service, determine who receives health care. Living in a household enrolled in primary care teams favoured regular dental appointments. Thus, these findings may help policymakers improve health access by expanding coverage of dental services in primary health care.

Explaining public dental service utilization: A theoretical model

OBJECTIVES

Constructing and validating a theoretical model of relationships between dental services use and socioeconomic characteristics, oral health status, primary care coverage, and public dental services.

METHODS

The first stage of the study consisted of developing a theoretical-conceptual model to demonstrate the expected relationships between variables based on the literature. In the second stage, we tested the proposed theoretical model using the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique, using data from the Brazilian National Health Survey conducted in 2019 with a sample of 41,664 individuals aged 15 or older.

RESULTS

This study successfully defined a theoretical model that explains the systematic relationships involving public dental services utilization. Socioeconomic status was negatively associated with oral health status (β = -0.376), enrollment in primary care facilities (β = -0.254), and the use of public dental consultations (β = -0.251). Being black, indigenous, or living in a rural area was directly associated with lower socioeconomic status and greater use of public dental services.

CONCLUSIONS

The identified relationships, establishing a theoretical basis for further investigations, also provide evidence of a public access policy's effect on oral health services on equity, supporting the construction of more effective and equitable public policies.

Influence of sociodemographic factors and Family Health Strategy coverage on oral health promotion procedures: an analysis of Brazilian municipalities in 2019

Background

The aim of the study was to investigate associations between sociodemographic factors and municipal Family Health Strategy (FHS) coverage and oral health promotion (OHP) procedures in Brazil.

Material and Methods

Data were obtained using public information systems and by direct request to the Ministry of Health. Clinical and collective OHP procedures performed in 2019 were analyzed, and sociodemographic covariates were associated with FHS coverage (population covered by FHS teams [FHST] and oral health teams [OHT]). Negative binomial regression models associated outcomes with covariates and estimated the prevalence ratio (PR) and confidence intervals (95%CI).

Results

A total of 4,913 municipalities were included. Municipalities with low-income inequality (PR=1.04, 95%CI 1.01 to 1.08), high illiteracy rate (RP=1.06, 95%CI 1.00 to 1.13), and population size of 10,001 to 50,000 inhabitants (PR=1.07, 95%CI 1.02 to 1.12) and 50,001 to 100,000 (PR=1.21, 95%CI 1.12 to 1.30) showed a higher frequency of clinical procedures. In contrast, a low frequency of clinical procedures was associated with reduced vulnerability to poverty (PR=0.83, 95%CI 0.78 to 0.89) and low OHT coverage (PR=0.39, 95%CI 0.33 to 0.45). Regarding collective procedures, the final model showed associations between low frequency and reduced income inequality (PR=0.91, 95%CI 0.87 to 0.95), low per capita income (PR=0.84, 95%CI 0.81 to 0.88), and low (PR=0.53, 95%CI 0.35 to 0.80) and medium Human Development Index (PR=0.79, 95%CI 0.71 to 87).

Conclusions

Clinical and collective OHP procedures were associated with sociodemographic conditions and OHT coverage in the FHS. Key words:Health Promotion, Oral Health, Social Determinants of Health, Universal Health Coverage.

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.

Pathways of socioeconomic inequalities in self-perceived oral health

Although there is a large body of evidence of the influence of social determinants on oral health, information on the mechanisms by which these determinants operate is poorly documented. Therefore, we aimed to investigate the pathways through which socioeconomic inequalities may influence self-perceived oral health (SPOH) in Brazilian adults. This cross-sectional study used data from the National Health Survey (NHS) of 2019, with a representative sample of adults aged 18 to 59 years (n = 65,803). The outcome was SPOH, assessed by a global self-item. Structural equation modeling was used to test direct and indirect pathways connecting a latent variable for socioeconomic position (SEP) to SPOH via psychosocial, behavioral, and biological factors. Higher SEP was directly associated with better SPOH [standardized coefficient (SC) = 0.069; p < 0.01)] fewer depressive symptoms (SC = -0.059; p < 0.01), fewer missing teeth (SC = 0.131; p < 0.01), and more healthy behaviors (SC = 0.643; p < 0.01). Fewer depressive symptoms (SC = -0.141; p < 0.01), more healthy behaviors (SC = 0.242; p < 0.01), and fewer missing teeth (SC = 0.058; p < 0.01) were directly associated with good SPOH. Among specific indirect effects of SEP on SPOH, the behavioral pathway was the one that best explained this association (SC = 0.155). Socioeconomic inequities in SPOH are mediate by psychosocial, behavioral, and biological factors. This has implications for positioning health strategies in the social context in which people live, to facilitate healthy choices and promote good oral health.

Socioeconomic inequalities in the utilization of dental services among adults in Saudi Arabia

Background

This study used the Anderson Behavioral Model to assess the socioeconomic inequalities in dental services utilization among adults in Saudi Arabia, along with other predictors of utilization, to inform future planning of dental care services.

Methods

This cross-sectional study was a secondary analysis using national data from the 2019 Kingdom of Saudi Arabia World Health Survey (KSAWHS). The survey consisted of two interviewer-administered questionnaires: one household and one individual interview. The questions covered predisposing factors (age, gender, marital status, nationality, education, employment), enabling factors (income, household wealth, area-based socioeconomic class, health insurance, eligibility for free governmental health care, transportation and region of residence) and self-reported need for dental treatment. The main outcome was dental utilization in the past year; predisposing, enabling and need factors were independent variables. Hierarchical logistic regression analyses identified significant predictors of dental utilization, applying survey weights to adjust for the complex survey design. Adjusted odds ratios with 95% confidence intervals and p values were reported in the final model.

Results

The final dataset included 8535 adults (response rate = 95.4%). Twenty percent of adults had visited the dentist at least once in the past year (95% CI 18–21%). There were socioeconomic inequalities in dental utilization. High household income (OR 1.43, p = 0.043), second and middle household wealth status (OR 1.51, p = 0.003 and OR 1.57, p = 0.006) and access to free governmental health care (OR 2.05, p = 0.004) were significant predictors in the final regression model along with perceived need for dental treatment (OR 52.09, p < 0.001).

Conclusion

Socioeconomic inequalities in the utilization of dental services exist in Saudi Arabia. The need for treatment was the strongest predictor suggesting predominantly symptomatic attendance. Increasing awareness about the importance of preventive dental visits rather than symptomatic attendance could be an important policy implication to improve oral health and optimize dental care expenditure. Further research should explore the drivers for adults to seek preventive care in the absence of any recognized dental problems.
