Decomposition Analysis of Socioeconomic Inequalities in Utilization of Oral Health Services: A Population-Based Study in Urban and Rural Households of Ahvaz.

Inequality in the use of dental services is a primary concern of global health, and few studies have been done in this field in Iran. Therefore, the present study aimed to conduct a decomposition analysis of socioeconomic inequalities in the utilization of oral health services. This was a cross-sectional study in which 715 households, including 2680 people living in Ahvaz, were included using a stratified-cluster sampling. Data were collected using a questionnaire. For data analysis and estimating the elasticity of the influencing factors, the logistic model and Stata software were used. The social and economic disparities in oral health variables were broken down into determinant components using the Van Doorslaer and Wagstaff technique. The key factors determining social and economic inequalities in the utilization of these services were insurance status, education level, income quintile, and occupation. Nearly 31% of utilization inequalities can be attributed to the insurance status of households. In addition, the education level of household members (about 28%) was the second factor of inequality. The variables of income quintile and occupation are also considered as the third factor, and the age of household members had a negative role in the socioeconomic inequality. The utilization of oral health services can be improved by improving economic and social variables in society. Therefore, including oral health services in insurance plans and primary health care services and supporting people with low-income levels can play an important role in reducing these inequalities.

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

BackgroundThis 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.MethodsThis 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.ResultsThe 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).ConclusionSocioeconomic 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.

Are there socio-economic inequalities in utilization of predictive biomarker tests and biological and precision therapies for cancer? A systematic review and meta-analysis

BackgroundNovel biological and precision therapies and their associated predictive biomarker tests offer opportunities for increased tumor response, reduced adverse effects, and improved survival. This systematic review determined if there are socio-economic inequalities in utilization of predictive biomarker tests and/or biological and precision cancer therapies.MethodsMEDLINE, Embase, Scopus, CINAHL, Web of Science, PubMed, and PsycINFO were searched for peer-reviewed studies, published in English between January 1998 and December 2019. Observational studies reporting utilization data for predictive biomarker tests and/or cancer biological and precision therapies by a measure of socio-economic status (SES) were eligible. Data was extracted from eligible studies. A modified ISPOR checklist for retrospective database studies was used to assess study quality. Meta-analyses were undertaken using a random-effects model, with sub-group analyses by cancer site and drug class. Unadjusted odds ratios (ORs) and 95% confidence intervals (CIs) were computed for each study. Pooled utilization ORs for low versus high socio-economic groups were calculated for test and therapy receipt.ResultsAmong 10,722 citations screened, 62 papers (58 studies; 8 test utilization studies, 37 therapy utilization studies, 3 studies on testing and therapy, 10 studies without denominator populations or which only reported mean socio-economic status) met the inclusion criteria. Studies reported on 7 cancers, 5 predictive biomarkers tests, and 11 biological and precision therapies. Thirty-eight studies (including 1,036,125 patients) were eligible for inclusion in meta-analyses. Low socio-economic status was associated with modestly lower predictive biomarker test utilization (OR 0.86, 95% CI 0.71–1.05; 10 studies) and significantly lower biological and precision therapy utilization (OR 0.83, 95% CI 0.75–0.91; 30 studies). Associations with therapy utilization were stronger in lung cancer (OR 0.71, 95% CI 0.51–1.00; 6 studies), than breast cancer (OR 0.93, 95% CI 0.78–1.10; 8 studies). The mean study quality score was 6.9/10.ConclusionsThese novel results indicate that there are socio-economic inequalities in predictive biomarker tests and biological and precision therapy utilization. This requires further investigation to prevent differences in outcomes due to inequalities in treatment with biological and precision therapies.

Geographical and socioeconomic inequalities in the utilization of maternal healthcare services in Nigeria: 2003\u20132017

BackgroundMaternal mortality has remained a challenge in many low-income countries, especially in Africa and in Nigeria in particular. This study examines the geographical and socioeconomic inequalities in maternal healthcare utilization in Nigeria over the period between 2003 and 2017.MethodsThe study used four rounds of Nigeria Demographic Health Surveys (DHS, 2003, 2008, 2013, and 2018) for women aged 15–49 years old. The rate ratios and differences (RR and RD) were used to measure differences between urban and rural areas in terms of the utilization of the three maternal healthcare services including antenatal care (ANC), facility-based delivery (FBD), and skilled-birth attendance (SBA). The Theil index (T), between-group variance (BGV) were used to measure relative and absolute inequalities in the utilization of maternal healthcare across the six geopolitical zones in Nigeria. The relative and absolute concentration index (RC and AC) were used to measure education-and wealth-related inequalities in the utilization of maternal healthcare services.ResultsThe RD shows that the gap in the utilization of FBD between urban and rural areas significantly increased by 0.3% per year over the study period. The Theil index suggests a decline in relative inequalities in ANC and FBD across the six geopolitical zones by 7, and 1.8% per year, respectively. The BGV results do not suggest any changes in absolute inequalities in ANC, FBD, and SBA utilization across the geopolitical zones over time. The results of the RC and the AC suggest a persistently higher concentration of maternal healthcare use among well-educated and wealthier mothers in Nigeria over the study period.ConclusionWe found that the utilization of maternal healthcare is lower among poorer and less-educated women, as well as those living in rural areas and North West and North East geopolitical zones. Thus, the focus should be on implementing strategies that increase the uptake of maternal healthcare services among these groups.

Socioeconomic inequalities in the utilisation of hypertension and type 2 diabetes management services in Indonesia.

SummaryObjectivesTo describe socioeconomic inequalities in the utilisation of hypertension and type 2 diabetes (T2D) management services in the Indonesian population and to determine whether education level and geographical location contribute to inequalities.MethodsCross‐sectional study using data from the 2014 Indonesia Family Life Survey (N = 30 762 for hypertension; N = 6758 for T2D). Socioeconomic status was measured by household consumption. The prevalence of hypertension and T2D was determined using internationally standardised clinical measurement, while disease management was defined by participation in screening and current use of medication. The relative index of inequality (RII) was used to estimate inequalities, adjusted to education level and geographical location.ResultsFor all household consumption quintiles, we observed low rates of screening participation for T2D and low medication use in both hypertension and T2D. We found socioeconomic inequalities in screening participation for hypertension (RII 2.68, 95% CI 2.42–2.96) and T2D (RII 7.30, 95% CI 5.48–9.72) and also for medication use in hypertension (RII 3.09, 95% CI 2.28–4.18) and T2D (RII 2.81, 95% CI 1.09–7.27). Education level contributed to socioeconomic inequalities in screening utilisation for both hypertension and T2D. Geographical location contributed to inequalities in screening utilisation and medication use for T2D. Socioeconomic inequalities in medication use for hypertension and T2D were larger among men than women.ConclusionsLarge socioeconomic inequalities were found in the utilisation of hypertension and T2D management services in Indonesia. Improving affordability, availability and approachability of services is crucial to reduce such inequalities.

Decomposing the Socio-economic Inequalities in Utilization of Full Antenatal Care in Jharkhand State, India

It is widely evidenced that low socio-economic status is significantly associated with poor health, but inequalities caused by social and economic factors are poorly quantified. This paper attempts to measure contributions of selected factors to the differences in full antenatal care (ANC) utilization in the state of Jharkhand, India, based on the third wave of District Level Household and Facility Survey (DLHS-3) data in 2007–2008. Full ANC is defined as having a minimum of three antenatal visits, at least two tetanus toxoid injections and receiving folic acid tablets for at least 90 days or more during the last pregnancy. Multivariate and decomposition statistical techniques were employed to examine the factors associated with utilization of ANC services and their contributions to inequalities in utilization. Results show that the factors with the largest contribution to utilization of ANC services were poor economic status of women (37.53%), mass media exposure (30.71%), and residence in a rural area (15.56%). The relative contributions of region, mothers’ education, age, and birth order of the women in generating inequalities were small. Therefore, to improve maternal health and to reduce socio-economic gaps in the state, more focus is needed on vulnerable sections of society and regions where the effects of government health programs hardly reach.

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

BackgroundTurkish 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. MethodsWe 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. ResultsThere 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). ConclusionPro-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.

Local level inequalities in the use of hospital-based maternal delivery in rural South Africa.

BackgroundThere is global concern with geographical and socio-economic inequalities in access to and use of maternal delivery services. Little is known, however, on how local-level socio-economic inequalities are related to the uptake of needed maternal health care. We conducted a study of relative socio-economic inequalities in use of hospital-based maternal delivery services within two rural sub-districts of South Africa.MethodsWe used both population-based surveillance and facility-based clinical record data to examine differences in the relative distribution of socio-economic status (SES), using a household assets index to measure wealth, among those needing maternal delivery services and those using them in the Bushbuckridge sub-district, Mpumalanga, and Hlabisa sub-district, Kwa-Zulu Natal. We compared the SES distributions in households with a birth in the previous year with the household SES distributions of representative samples of women who had delivered in hospitals in these two sub-districts.ResultsIn both sub-districts, women in the lowest SES quintile were significantly under-represented in the hospital user population, relative to need for delivery services (8% in user population vs 21% in population in need; p < 0.001 in each sub-district). Exit interviews provided additional evidence on potential barriers to access, in particular the affordability constraints associated with hospital delivery.ConclusionsThe findings highlight the need for alternative strategies to make maternal delivery services accessible to the poorest women within overall poor communities and, in doing so, decrease socioeconomic inequalities in utilisation of maternal delivery services.

Socio-economic inequalities in health care utilisation in Norway: a population based cross-sectional survey.

BackgroundNorway provides universal health care coverage to all residents, but socio-economic inequalities in health are among the largest in Europe. Evidence on inequalities in health care utilisation is sparse, and the aim of this population based study was to investigate socio-economic inequalities in the utilisation of health care services in Tromsø, Norway.MethodsWe used questionnaire data from the cross-sectional Tromsø Study, conducted in 2007–8. All together 12,982 persons aged 30–87 years participated with the response rate of 65.7%. This is slightly more than one third of the total population (33.8%) in the mentioned age group in Tromsø municipality. By logistic regression analyses we studied associations between household income, education and self-rated occupational status and the utilisation of general practitioner, somatic and psychiatric specialist outpatient services. The outcome variables were probability and frequency of use during the previous 12 months. Analyses were stratified by gender and adjusted for age, marital status, and self-rated health.ResultsSelf-rated health was the dominant predictor of health care utilisation. Women’s probability of visiting a general practitioner did not vary by socio-economic status, but high income was associated with less frequent use (odds ratio [OR] for trend 0.89, 95% confidence interval [CI] 0.81-0.98). In men, high income predicted lower probability and frequency of general practitioner utilisation (OR for trend 0.85, CI 0.76-0.94, and 0.86, 0.78-0.95, respectively). Women’s probability of visiting a somatic specialist increased with higher income (OR for trend 1.11, CI 1.01-1.21) and higher education (OR for trend 1.27, CI 1.16-1.39). We found the same trends for men, though significant only for education (OR for trend 1.14, CI 1.05-1.25). The likelihood of visiting psychiatric specialist services increased with higher education and decreased with higher income in women (OR for trend 1.57, CI 1.24-1.98, and 0.69, 0.56-0.86, respectively), but did not vary significantly by socio-economic variables in men. Higher income predicted more frequent use of psychiatric specialist services in men (OR for trend 2.02, CI 1.12-3.63).ConclusionsThis study revealed important inequalities in the utilisation of health care services in Norway, inequalities which may contribute to sustaining inequalities in health outcomes.
