Socioeconomic inequalities linked to the transitioning to neurocognitive disorders and mortality

Research on socioeconomic position (SEP) and mild neurocognitive impairment, considered a transient state between normal cognitive function and dementia is limited. The purpose of this study was to determine the role of SEP in transitioning between different cognitive states and mortality risk. Using nationally representative English data and utilising a multistate model association between SEP and the risk of transitioning from no cognitive impairment (NOCI) to Cognitive impairment no dementia (CIND), dementia and death were investigated. The potential reverse transition from CIND to NOCI was also explored. The probabilities of transitioning between cognitive states and time spent in each state differed significantly between those with lower and higher levels of SEP. Higher wealth was associated with a reverse transition from CIND to NOCI [HR = 1.56, CI (1.42,1.72)]. Socioeconomic advantage might protect against the progression to the early stages of neurocognitive disorders (CIND) and facilitate the potential reversion from mild cognitive impairment to a healthy cognitive state in later life. Lower levels of education affect the risk of mortality after the onset of dementia.

Analysis of NSSO data sets for a spatial evaluation of water and housing inequality in India

Achieving all Sustainable Development Goals by 2030 to meet basic needs and improve quality of life has become ever more significant. This study examines the accessibility and factors affecting safe drinking water and housing across India's socioeconomic strata to support Sustainable Development Goals (SDG) 06 and 11. The study also assesses government programs that provide affordable housing and safe water. This study analyses key aspects of the 76th National Social Survey on Housing and Sanitation (NSSO WASH) data on housing conditions and drinking water to determine how each component affects people's standard of living. Descriptive analysis, probit, and multinomial logistic regressions were used to tabulate socioeconomic factors such household size, location, gender, income, education, occupation type, social group, and scheme recipient. Our study found that there was 20% more likely that households in the lowest quintile income bracket have access to clean drinking water; thanks to government schemes like the National Rural Drinking Water Programme and Atal Mission for Rejuvenation and Urban Transformation. Due to socioeconomic inequities, some social groups are more likely to lack safe water services, according to the study. Gender and education, especially female family members, affect access to basic needs. Rural households get 26% less safe drinking water than urban households. Vulnerable groups face lack of access to clean water and safe housing/shelter due to these gaps. Further, a new composite index has been devised to assess housing and clean water inequalities across Indian states. To achieve the Sustainable Development Goals, research recommends increased government initiatives and investments, as well as appropriate monitoring and evaluation mechanisms, for WASH conditions, boosting women's education and awareness in suboptimal states.

IMPACT OF POLITICAL APATHY ON THE DEMOCRATIC PROCESS AND GOVERNANCE IN NIGERIA

This study investigates the multifaceted impact of political apathy on the democratic process and governance in Nigeria, with a focus on local government elections in Ogun State. Through a descriptive research design, data was collected from 230 male and female adults in Ogun State, employing stratified and simple random sampling methods. Statistical analysis, including means and correlation analysis, was utilized to examine factors contributing to political apathy, manifestations of apathy, and its consequences on governance. The findings revealed widespread agreement among respondents regarding factors contributing to political apathy, including corruption, ethnic and religious divisions, and socio-economic disparities. Moreover, low voter turnout, limited civic engagement, and elite capture of political institutions are identified as manifestations of political apathy, undermining democratic principles such as representation and accountability. The consequences of political apathy on governance are profound, exacerbating socio-economic inequalities and eroding democratic legitimacy and accountability. Recommendations are provided to address these challenges, including comprehensive governance reforms, promotion of civic engagement, and initiatives to address socio-economic inequalities. These findings underscore the urgent need for proactive measures to combat political apathy and revitalize democratic governance in Nigeria, emphasizing the importance of transparency, inclusivity, and accountability in political processes.

Accessing the Impact of Policy Reforms on the Rights to Education: A Comparative Study of Emerging and Developed Economies (Nigeria and the U.S. )

This study examined the impact of education policy reforms on the right to education in emerging and developed economies, focusing on Nigeria and the United States. It analyzed how policy interventions shaped access to education, the quality of educational outcomes, and equity in both countries. The key research questions investigated the effectiveness of education reforms in improving access, addressing regional and socioeconomic disparities, and ensuring quality education. The study adopted a comparative case study methodology, analyzing secondary data, policy documents, and education statistics from both nations. Theoretical frameworks such as Human Capital Theory and a rights-based approach to education were used to evaluate the policies' impact. Findings revealed that while Nigeria made significant strides in increasing school enrollment through policies like the Universal Basic Education (UBE) program, it struggled with quality, funding, and regional disparities. In contrast, the U.S. achieved widespread access to education but faced persistent challenges related to racial and socioeconomic inequities, influenced by the shortcomings of standardized testing and uneven funding allocation. The study’s implications suggested that addressing policy implementation, funding, and equity issues is essential for advancing the right to education. Recommendations were provided to strengthen reforms, improve funding mechanisms, and promote equitable access to quality education in both contexts.

Language-in-Education Planning for Foreign Languages in Morocco: Analyzing the Historical and Structural Impacts of History, Social Class, Ideology, and Power Dynamics

The present paper analyzes language-in-education planning for foreign languages within the Moroccan educational system. These policies have been adopted and/or implemented as part of three successive educational reforms that the state has undergone in the last 25 years (e.g., the National Charter 1999, the Emergency Program 2008, and the Strategic Vision 2015). Despite the state’s advocacy for varying foreign language instruction, these policies have been marked by a consolidation of French instruction as a primary foreign language and a shift to using it as a medium of instruction for science and technology subjects in middle and secondary education as part of language alternation pedagogy. The study adopts Tollefson’s (1991) Historical-Structural Approach as a conceptual framework to analyze how the constructs of history, class structures, ideology, and power dynamics have influenced language-in-education planning to perpetuate the social, economic, and political privileges of a francophone-oriented elite. The latter have employed their economic and political power to influence the indecisive aspect of the language-in-education policies—both covertly and overtly—to increase socioeconomic inequalities and injustices, including linguistic disparities between the elite and lower social classes. This dominant position of French within the educational system has also been motivated by external influences, manifested in the heavy political and economic relationship with France, the former colonizer.

Swift action: scrutinizing emergency measures from the COVID-19 pandemic

This manuscript evaluates India’s emergency measures during the COVID-19 pandemic. Key actions including a nationwide lockdown to curb virus spread and strengthen healthcare infrastructure are thoroughly studied and its effects analysed. Healthcare responses included scaling up testing, medical supplies, and using the “Aarogya Setu” app for contact tracing are briefly looked at to assess effectiveness of the policies implemented by the government. The largest vaccination drive in the world which covered the vast population was no mean feat and worth applauding. Challenges included supply chain disruptions, healthcare disparities, and socio-economic inequalities. Comparisons with global practices highlighted areas for improvement. The evaluation underscores the importance of swift, adaptable, and inclusive policy measures, offering valuable lessons for future pandemic preparedness. The article aims to outline the various measures undertaken by the government and determine the effectiveness of them in controlling the outbreak of COVID-19 in the country.

Psychosocial factors mediate social inequalities in health-related quality of life among children and adolescents

BackgroundThe present analysis aimed to assess the mediating role of psychosocial and behavioural factors in socio-economic inequalities in health-related quality of life (HRQoL) among children and adolescents.MethodsCross-sectional data was drawn from the randomly selected SEROCoV-KIDS cohort study in Geneva, Switzerland. Associations of socio-economic conditions (parents’ highest education, household financial situation) with HRQoL, psychosocial (parent–child relationship, school difficulties, friends, extracurricular activities) and behavioural factors (screen time, physical activity, green spaces time, sleep duration), along with associations of psychosocial and behavioural factors with HRQoL, were evaluated with generalized estimating equations. Counterfactual mediation analyses were conducted to test pathways linking socio-economic conditions to HRQoL.ResultsOf 965 children and 816 adolescents, those with disadvantaged financial circumstances were more likely to have a poor HRQoL (adjusted Odds Ratio [aOR]: 3.80; 95% confidence interval [CI]: 1.96–7.36 and aOR: 3.66; 95%CI: 2.06–6.52, respectively). Psychosocial characteristics mediated 25% (95%CI: 5–70%) and 40% (95%CI: 18–63%) of financial disparities in HRQoL among children and adolescents, respectively. Health behaviours were weakly patterned by socio-economic conditions and did not contribute to financial differences in HRQoL.ConclusionsThese findings provide empirical evidence for mechanisms explaining socio-economic disparities in child HRQoL and could inform interventions aimed to tackle health inequalities.

Addressing the Anthropocene from the Global South: integrating paleoecology, archaeology and traditional knowledge for COP engagement

The triple planetary crisis of climate change, pollution, and biodiversity loss necessitates more holistic, comprehensive, and integrated public policy approaches. Within the United Nations Framework Convention on Climate Change, this crisis highlights significant conflicts over forms of knowledge and conceptualization, affecting how international policies are formed. Indigenous knowledge systems have become increasingly acknowledged for their vital role in addressing the challenges of the Anthropocene. Conferences of the Parties institutions like the International Indigenous Peoples Forum on Climate Change emphasize the critical, although not always recognized, importance of Indigenous territories, which contain eighty percent of the world’s biodiversity. Here, we show that research in paleoecology, archaeology and history demonstrates the long-term significance of traditional knowledge and Indigenous land management practices for contemporary ecosystem dynamics. Drawing from these varied studies and perspectives also reveal the socio-economic inequalities resulting from centuries of European colonialism. We showcase three case studies on; (i) pastoralism in eastern Africa, (ii) natural resource management in southeast Asia and (iii) adaptation to sea level rise in the Caribbean, which touch upon highly diverse human resilience strategies across space and time. Despite efforts at the COP28 to accelerate climate action and incorporate diverse knowledge systems, significant challenges remain. The need for a pluralistic knowledge, rather than a one-size-fits-all approach, blending scientific language with artistic and narrative forms, is proposed as critical for fostering effective communication and developing more effective and equitable solutions for global environmental governance.

Rural-urban differentials in undernutrition among women in India: Evidence from a decomposition approach.

Background: Global healthcare and nutrition policies have not eliminated the pressing public health issue of undernutrition, which remains a paramount public health concern in countries like India, coinciding with overweight and obesity, in the form of dual burden of malnutrition. Aim: This study delves into the rural-urban differential in undernutrition among reproductive-aged women in India for targeted policy interventions and to achieve universal health coverage. Methods: Data from the recent iteration of the National Family Health Survey (NFHS-5; 2019-21) were utilized to examine the factors influencing rural-urban differentials in women's undernutrition. A set of logistic regression and Fairlie's decomposition analysis are employed to identify the associated covariates and understand the factors driving these differentials. Results: The analysis reveals that rural women are significantly more vulnerable to undernutrition compared to urban counterparts, with factors such as education, wealth status, age, and dietary diversity playing key roles. The decomposition analysis of the rural-urban gap revealed that the variables considered in the study accounted for approximately 75% of the disparity. The difference in household wealth between rural and urban areas contributed about 63% of the explained gap, followed by educational status (16%), age group (11%), dietary diversity (8%), religion (5%), and media exposure (4%). Conclusion: The findings underscore the importance of targeted interventions addressing socio-economic inequalities to mitigate undernutrition among women in India. Enhancing access to education, improving economic opportunities, promoting dietary diversity, and challenging cultural norms are crucial steps towards achieving equitable nutritional outcomes and reducing the existing rural-urban disparity.

Bibliometric Analysis on the Dynamics of Income Inequality in the Digital Economy

This study utilizes bibliometric analysis to explore the evolving discourse surrounding income inequality in the digital economy, identifying key thematic shifts and central scholarly contributions from 2000 to 2024. By employing VOSviewer to map keywords and author networks, the research reveals a significant transition in academic focus—from traditional aspects of economic disparity to more complex issues such as digital inequality and globalization. The findings underscore the increasing concern over how digital advancements intersect with and potentially exacerbate socioeconomic inequalities. A detailed examination of author collaborations suggests a robust, albeit evolving, network of scholarship that highlights the need for more interdisciplinary approaches and integration of emerging researchers into mainstream discourse. This study not only provides a comprehensive overview of the academic landscape but also offers insights into the practical implications for policy aimed at mitigating inequality in the digital age.

Socioeconomic inequalities in cervical cancer screening in sub-Saharan Africa: Decomposition analysis

Abstract Background Cervical cancer remains prevalent in sub-Saharan Africa (SSA). Despite global efforts to eliminate this disease, its incidence continues to rise due to barriers in screening, vaccination, and treatment access. While studies address access barriers, little has explored inequality, often limited to single countries. Here, we examine socioeconomic inequalities in cervical cancer screening in SSA. Methods Data from the Demographic and Health Surveys of 10 SSA countries was used for the analysis. We stratified the study by wealth index and educational attainment as a measure of socioeconomic status. Socioeconomic status inequalities in cervical cancer screening were constructed using concentration curves. We then computed the concentration index to quantify socioeconomic inequality. To examine the factors associated with high socioeconomic inequality in cervical cancer screening, a decomposition analysis was conducted. Results Concentration curves showed screening uptake skewed towards the wealthy and educated across all countries, reflected by positive concentration indices (CIX=0.21; p-value<0.0001) except in Burkina Faso and Mauritius. Decomposition analysis revealed significant positive concentration indices for women with complete secondary (CIX=0.74) and higher education (CIX=0.91), those in the richest wealth index (CIX=0.35), separated women (CIX=0.08), currently working women (CIX=0.02), as well as those who were exposed to reading newspaper/magazine (CIX=0.19), listening to radio (CIX=0.10), and watching TV (CIX=0.44). Conclusions Cervical cancer screening in SSA exhibits pro-rich and pro-higher educational inequalities. Urgent interventions are needed to restructure existing screening programs to prioritize accessibility and inclusion, particularly for women from poorer households and with a lower level of education. These findings are vital for policymakers and public health practitioners to address cervical cancer screening disparities in SSA. Key messages • Addressing socioeconomic inequalities in cervical cancer screening is crucial for improving public health in sub-Saharan Africa. • Combatting socioeconomic disparities in cervical cancer screening is critical for achieving health equity in sub-Saharan Africa.

7.X.1. Providing BoD estimates on a regional level – necessity in assessing health inequalities

Abstract Burden of disease indicators, such as Disability-adjusted life years (DALY), Years lost due to disability (YLD) and Years lost due to death (YLL) have become standard indicators in public health reporting systems. Due to the combination of morbidity and mortality, the DALY provides valuable information on the burden due to specific diseases. These tools are employed by policymakers to devise intervention programs with the objective of enhancing the collective health of the population. Studies at the subnational level offer a greater added value to the public health information systems. Identifying variations in health outcomes and disease burden across different regions is a key factor when introducing targeted interventions and allocating resources. Health inequalities persist also in countries with good health systems and well-developed welfare state. There are notable contrasts in the political, economic and social environments across Europe. Moreover, the European countries are at different stages of the epidemiological transition, which encompasses a range of factors influencing health and modifiable risk behaviours. These differences are determined by socioeconomic inequalities at national and sub-national level, such as municipalities, counties and others. It is therefore imperative to provide BoD indicators at the most possible detailed regional-level and to link this information with further indicators such as deprivation indexes or Gini coefficients. Obtaining regional-level data for BoD analysis and health inequalities is not straightforward and can pose many challenges. Data availability is usually scarce and may involve significant resources in collecting it. Data quality and data completeness can also pose challenges in the reporting systems, which can result in under-reporting of certain diseases and overlooking health problems in the population. Also, countries with smaller populations are confronted with the challenge of a limited number of cases, which poses difficulties in obtaining regional estimates. The following workshop presents examples from European BoD studies, that have analysed health inequalities at regional level. The first presentation shows a country comparison study of the overall YLL and their association with socioeconomic and geographical inequalities. The second is from an Estonian study, representing a country with a small population that has developed its own methodology for assessing regional health issues. The third presentation from the German BoD study presents results on 96 spatial planning regions, which have been combined with the German index of socioeconomic deprivation. The final presentation brings example from Norway, where the association between YLL and education and income is examined at municipality level. Key messages • By comparing BoD estimates at the regional level, policymakers and public health officials can identify areas with higher disease burdens, indicating potential health inequalities. • Linking information on BoD indicators with data on regional and socioeconomic inequalities is essential when monitoring developments and tailoring strategies in public health outcomes.

Do poor psychosocial resources mediate health inequalities in type 2 diabetes? The Maastricht Study

Abstract Low socioeconomic position (SEP) has been identified as a risk factor for type 2 diabetes mellitus (T2DM). A potential pathway of this association is psychosocial resources. Disadvantageous environmental conditions result in low control beliefs through adverse resources and inferiority beliefs through social comparison for people with a low SEP. We examined two poor psychosocial resources, low control beliefs and inferiority beliefs, to explain socioeconomic inequalities in T2DM. We analysed mediating roles of low control beliefs and inferiority beliefs by using counterfactual mediation analysis. 8293 participants aged 40-75 living in Limburg, the Netherlands participated in The Maastricht Study starting from September 2010 to October 2020 and were followed up to 10 years with annual questionnaires with a median follow-up time of 7.18 years. SEP (education, income, occupation), control and inferiority beliefs, and (pre)diabetes by oral glucose tolerance test were measured at baseline. Incident T2DM was self-reported per annum. 3.2%(N = 203) of the participants without T2DM at baseline reported incident T2DM. People with low SEP had more often prevalent and incident T2DM (e.g., low education:HR=2.13, 95%CI:1.53-2.97). Lower control beliefs and higher inferiority beliefs were more common among people with low SEP than people with high SEP. Moreover, lower control beliefs and higher inferiority beliefs were risk factors for T2DM (e.g., low control beliefs: HR = 1.50, 95%CI:1.08-2.09). The relationship between SEP and T2DM was partially mediated by control beliefs (7.98-13.56%) and inferiority beliefs (2.16-4.53%). Poor psychosocial resources are important in socioeconomic inequalities in diabetes. Researchers and practitioners should consider the psychosocial profile of people with lower SEP might differ from those with higher SEP and this might interfere with the development, treatment, and prevention of T2DM. We should aim to work with such beliefs, instead of against it. Key messages • Socioeconomic health inequalities in diabetes has many underlying mechanism including psychosocial pathways. • Interventions and research should consider the different environment of low SEP and psychosocial profiles of people. We should aim to work with it, instead of against it.

The role of class stigma in socioeconomic inequalities in type 2 diabetes: The Maastricht Study

Abstract Background Low socioeconomic position (SEP) is a risk factor for type 2 diabetes mellitus (T2DM). An underlying mechanism behind socioeconomic health inequalities can be stigma, particularly classism. Studying the influence of class stigma in the context of (pre)diabetes and socioeconomic inequalities may shed light on the societal factors influencing diabetes. Methods Data from 1947 participants aged 49-88 who participated in the second phase of The Maastricht Study starting between November 2020 and April 2023 were used. SEP (education, income, occupation) and 6-item classism scale were measured through self-reported questionnaires. (Pre)diabetes was measured through an oral glucose tolerance test. We conducted multinomial logistic regression analyses to investigate the associations between SEP, classism, and diabetes status. Results 20.9% (N = 406) of the study sample had T2DM (Mage=69.8(±6.8) years; 31.3% women). People with low SEP had more often T2DM (e.g., income OR = 2.13, 95%CI:1.54-2.82) and reported perceived classism (e.g., education OR = 2.07, 95%CI:1.33-3.21) than people with high SEP. Classism was not statistically significantly associated with T2DM (OR = 0.78, 95%CI:0.48-1.29). Conclusions Social health inequalities are apparent in T2DM; however, our results suggest that class stigma might not be a major factor in underlying processes. Further research can investigate the role of chronic stress and intersection of multiple stigmas. Key messages • The underlying factors behind socioeconomic health disparities are complex. Social and psychological environment in low SEP should be investigated carefully. • Although low SEP is strongly associated with T2DM and perceived classism, class stigma might not be a major target in explaining socioeconomic pathways in diabetes.

Socioeconomic inequalities in substance use among Norwegian adolescents between 2014 and 2022

Abstract Background Increasing use of substances is observed among adolescents in recent years. Early onset of substance use dramatically increases the risk of substance use disorder, dependence, and poorer psychological, social, and physical health, and is thus a public health concern. We explore trends in socioeconomic inequalities in past year use of cannabis and other illicit drugs between 2014 and 2022 among Norwegian adolescents. Methods This study is based on data retrieved from five waves of the nationwide Norwegian Ungdata survey (2014-2022) among adolescents attending upper secondary education (N = 282,259; 51 % girls). Trends in socioeconomic inequalities were assessed using the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII). Results The use of cannabis and other illicit drugs increased among boys (from 13% to 19%, and from 2% to 5%, respectively) and girls (from 8% to 14%, and from 1% to 3%, respectively) between 2014 and 2022. Higher prevalence’s was observed among the least affluence girls between 2020 and 2022, both in absolute and relative terms (SII: 0.01 to 0.06, RII: 0.97 to 1.52, p < 0.001). No inequalities were observed among boys during this time. While relative and absolute inequalities in use of other illicit drugs decreased in boys, absolute inequalities increased in girls. Boys were more likely than girls to have used cannabis and other illicit drugs, although the gender gap in cannabis use narrowed slightly during the study period. Conclusions Our data suggest increasing use of cannabis and other illicit drugs among Norwegian adolescent boys and girls between 2014 and 2022. Future studies should examine the potential causes of increasing substance use as a basis for understanding, and distinguishing between, the many intertwining factors that influence adolescent drug use behaviors. Key messages • The use of cannabis and other illicit drugs increased between 2014 and 2022 among Norwegian boys and girls. • While inequalities in the use of cannabis and ither illicit drug use increased in girls, small or no inequalities was observed among boys.

Narrowing socioeconomic inequalities in coronary heart disease: insight from Mendelian randomization

Abstract Background Socioeconomic inequalities in coronary heart disease (CHD) represent a pressing global public health concern. However, which dimensions of socioeconomic status (SES) affect CHD and the potential modifiable mediators remain elusive. Methods We performed two-sample Mendelian randomization (MR) analyses based on summary data from large-scale genome-wide association studies in populations of European ancestry. Specifically, by applying bidirectional univariable MR (UVMR) and multivariable MR (MVMR), we investigated the causal relationships of education, occupation, income, Townsend deprivation index (TDI) with CHD and the independent effects of these SES indicators. We further employed a two-step MR to comprehensively profile the mediating effects of 23 behavioral, 3 psychological and 5 biological factors in the relationships. Results An independent causal association was observed between genetically predicated education and CHD, with a 30% lower risk of CHD (OR: 0.70; 95% CI: 0.53-0.93) for each 4.2-year of schooling. Each one-s.d. higher household income was causally, but not independently, associated with a 39% lower risk of CHD (OR: 0.61; 95% CI: 0.49-0.77). No significant causal association was suggested for occupation and TDI with CHD, and no reverse causal effect was observed for CHD on the SES indicators. Of 31 candidate mediators, nine factors mediated the effect of education on CHD significantly, with an individual mediation proportion of 33.5% for smoking, 29.2% for sedentary behaviour, 14.4% for blood lipids, 13.4% for BMI, 11.7% for systolic blood pressure, 9.5% for diastolic blood pressure, 7.8% for well-being spectrum, 6.4% for depression and 2.8% for blood glucose. Conclusions This study highlights that education was the primary SES indicator affecting CHD with considerable mediation by a number of modifiable risk factors. These findings inform policies to mitigate disparities of CHD risk attributable to socioeconomic inequalities. Key messages • Education can be prioritized over other common SES indicators as an essential strategy to reduce the burden of CHD. • Interventions for narrowing socioeconomic inequalities in CHD could focus on more easily modifiable mediating factors.

Welfare regimes and socioeconomic inequalities in edentulism: A multilevel analysis of 40 countries

Abstract Aim To evaluate the association between welfare regimes with edentulism and to investigate if it modifies the magnitude of socioeconomic inequalities in edentulism. Methods We analysed data from 40 high-, middle- and low-income countries collected between 2007 and 2018, encompassing 117397 individuals 20 years or older. The main outcome was edentulism and welfare regimes were the main exposure and effect modifier. Individual level variables were sex, age and quintiles of the wealth score. Multilevel logistic regression was used to estimate the odds of being edentulous and cross-level interaction terms between individual wealth and country factors were tested. Findings Individuals at the lowest wealth quintile had a consistently higher prevalence of edentulism. The highest age-sex standardised prevalence of edentulism was found in Eastern European countries (9.9%) followed by Informal Security (9.4%), while the lowest was among the Insecurity regime (1.4%) followed by the Social Democratic regime (4.7%). Liberal countries presented the highest magnitude of absolute and relative inequalities, where the lowest quintile had OR = 16.7 (95%CI: 10.5-26.5) times more chances of being edentulous and 14.4 percentage points higher prevalence. Low-income countries in the Insecurity Regime in social and labour market presented the lowest level of inequalities. Among HIC and upper-middle income countries, Social Democratic regime had the lowest absolute inequalities (4.0 percentage points difference between highest and lowest quintiles) and the Informal Security regime had the lowest relative differences between the highest and lowest quintiles (OR = 3.21, 95%CI: 2.83-3.63). Interpretation Our findings suggest that policies in some welfare regimes might improve oral health while reducing inequalities. High and upper-middle-income countries presented a high level of edentulism and inequalities. Key messages • Larger socioeconomic inequalities in edentulism were found in high-income countries with liberal policies. • A possible benefit of welfare policies on prevalence and inequalities in edentulism may be only evident among industrialised countries.

Exploring UK adult and policy stakeholder perspectives on obesity prevention policy and inequalities

Abstract In England, 14 obesity strategies have been published, including 689 proposed policies, while rates of obesity persist, and inequalities worsen. This study explores adults’ attitudes in relation to food-related obesity policy and how socioeconomic inequalities in obesity are considered throughout the policy process through the perspective of policy stakeholders (PSH). 31 semi-structured interviews with UK-based adults (GPP) (18+) and 14 interviews with PSH categorised as government officials, academics, and advocacy group representatives were conducted and analysed using Braun and Clarke’s thematic analysis. Both PSH and GPP attributed obesity causation primarily to the food environment rather than to individual behaviour. The PSH identified the food industry’s role in shaping the environment. Level of deprivation was believed to exacerbate the barriers to healthy weight in both samples. All participants agreed that, in the UK, there was an unequal opportunity to attain a healthy diet. A disconnect was found between the GPP perspectives towards the barriers to healthy weight and their attitudes towards policy action. The GPP described mistrust in the government’s motives and willingness, fuelling the perspective that policy lacked impact and was disconnected from their lived experiences, particularly among participants of lower socioeconomic status and higher weight classifications. The PSH raised concerns regarding barriers to policy implementation, including inconsistent government commitment, competing priorities, and resistance to state intervention. PSH suggested that it was unfeasible to prioritise inequalities while population rates remain high, and the failure of implement proposed policies continue. This study shows the necessity of incorporating a health equity lens, breaking down policy silos, and amplifying community voices in the policy process to challenge assumptions regarding lived experiences and ensure healthier equitable policy outcomes. Key messages • The study shows the importance of integrating a health equity lens, breaking policy silos, and amplifying community voices to challenge assumptions and achieve more equitable policy outcomes. • Obesity policy requires greater consideration to inequalities to strengthen policy impact as demonstrated by all participants recalling the unequal opportunity to sustain a healthy weight in the UK.

Socioeconomic inequalities in avoidable mortality: results from the Italian nationwide cohort

Abstract Background Inequalities in avoidable mortality have been well evaluated in many European countries. We aimed to assess the association between socioeconomic status and avoidable mortality in Italy. Methods The nationwide closed cohort of the 2011 Census of Population and Housing was followed up for 2012- 2019 mortality. Outcomes of preventable and of treatable mortality were evaluated among people aged 30-74. Exposures were education level and residence macro area (North-West, North-East, Center, South-Islands). Adjusted mortality rate ratios (MRRs) were estimated through multivariate quasi-Poisson regression models, by sex and group of causes, taking into account age at death and macro area of residence. Relative index of inequalities (RII) was estimated for preventable, treatable, and non-avoidable mortality and for some specific causes. Results The cohort consisted of 35,708,459 residents (48.8% men, 17.5% aged 65-74), 34% with a high school diploma, 33.5% living in the South-Islands; 1,127,760 deaths were observed, of which 65.2% for avoidable causes (40.4% preventable and 24.9% treatable). Inverse trends between education level and mortality were observed for all causes; comparing the least with the most educated groups, a strong association was observed for preventable (males MRR = 2.39; females MRR = 1.65) and for treatable causes of death (males MRR = 1.93; females MRR = 1.45). Highest RII were observed for HIV/AIDS and alcohol-related diseases (both sexes), drug-related diseases and tuberculosis (males), and diabetes mellitus, cardiovascular diseases, and renal failure (females). Higher risks of preventable and of treatable mortality were found for those living in the South-Islands. Conclusions We documented relevant socioeconomic inequalities in avoidable mortality in Italy, especially in the Southern regions. They represent a possible missed gain in health and suggest a reassessment of priorities and definition of health targets with the lens of equity. Key messages • An inverse socioeconomic gradient in avoidable mortality was observed in Italy, both for preventable and for treatable mortality, with geographical heterogeneity. • Greatest social disparities were found in mortality for causes strongly associated with risk behavior and for which it is possible to identify risk factors on which to intervene.

Monitoring inequities using routine administrative data: a case study of cancer screening in Ontario, Canada

Abstract Routine cancer screening is a critical primary care service to reduce cancer morbidity and mortality, through early detection, diagnosis, and treatment. We evaluated longitudinal changes in socioeconomic inequities in cancer screening in Ontario, Canada, by using linked provincial health administrative databases including 15.9 million records eligible for cancer screening. The rate of colorectal cancer screening increased between 2011 and 2020 (54% to 62%) with a reduction in the indices of inequity (slope index, SII: from 0.36 to 0.33; relative index of inequity, RII: from 0.69 to 0.54). However, the rate of cervical cancer screening decreased (from 76% to 68%), particularly in deprived areas (RII increasing from 0.47 to 0.54). Access to cancer screening is a challenge in deprived areas. Understanding the socio-economic determinants in access to screening across the life course can help develop tailored interventions to increase health equity.
