Priorities for research on equity and health: towards an equity-focused health research agenda

Representativeness in health research studies: an audit of Greater Manchester Clinical Research Network studies between 2016 and 2021

BACKGROUND

There are increasing concerns that participants in health research in the UK are not representative of the UK population, risking widening health inequities. However, detailed information on the magnitude of the problem is limited. Therefore, we evaluated if the health research conducted in the Greater Manchester region was broadly representative of its diverse population.

METHODS

We conducted an audit of all health  research studies conducted exclusively in Greater Manchester, using data from a national research network. Two researchers selected studies that were (1) an interventional or observational study of a health outcome; (2) 'closed' for recruitment between May 2016 and May 2021 and (3) human research. They extracted study information (dates, contacts, sample recruited, clinical speciality). Participant characteristics were sourced from published and unpublished manuscripts and requested directly from principal investigators and named study contacts. Data were extracted, summarised and compared to the Greater Manchester population for the following metrics: ethnicity, sex, age, deprivation and smoking status. A weighted mean age estimate was calculated to account for variation in age reporting. Too few studies provided patient-level deprivation data so, using the area code of the recruitment site, the area level multiple deprivation, health deprivation and disability index and decile was derived. These data were geo-mapped using QGIS 3.26.

RESULTS

Overall, 145/153 (95%) studies met inclusion criteria and participant information was sourced for 85/145 (59%) studies, representing 21,797 participants. Participant information was incomplete for all metrics. Where ethnicity (N = 10,259) data were available and compared to Greater Manchester estimates there was evidence that ethnic minorities were under-represented (6% versus 16%). Most of the recruitment occurred in central Manchester (50%) and with NHS hospital settings (74%).

CONCLUSIONS

Greater Manchester health research in 2016-2021 was centralised and under-represented ethnic minorities. We could not report which ethnic minority group was least represented because sourcing detailed participant information was challenging. Recommendations to improve the reporting of key participant characteristics with which to monitor representativeness in health research are discussed.

Admitting the heterogeneity of social inequalities: intersectionality as a (self-)critical framework and tool within mental health care

Inequities shape the everyday experiences and life chances of individuals at the margins of societies and are often associated with lower health and particular challenges in accessing quality treatment and support. This fact is even more dramatic for those individuals who live at the nexus of different marginalized groups and thus may face multiple discrimination, stigma, and oppression. To address these multiple social and structural disadvantages, intersectional approaches have recently gained a foothold, especially in the public health field. This study makes an empirically informed argument for the merits of increasing the use of intersectional frameworks in the mental health field. In the mental health field, the potential for greater attention to multiple unjustified disadvantages appears to be of particular importance, as many mental health service users already face stigma and discrimination because of their mental health issues and thus may benefit particularly frequently and far-reachingly from effective problem awareness about multiple disadvantages. Intersectional approaches may help address the complexity, interdependence, and mutual constitution of social inequalities better than previous approaches that examined only one category of sociostructural stratification. By helping to identify the needs of those at the greatest risk of poor health, intersectional frameworks and tools can contribute not only to better address the needs of multiple disadvantaged individuals with mental health issues but also to the promotion of equity in the field of mental health, contributing to the reduction of health disparities.

Integrating the social environment with an equity perspective into the exposome paradigm: A new conceptual framework of the Social Exposome

The importance of the social environment and social inequalities in disease etiology is well-known due to the profound research and conceptual framework on social determinants of health. For a long period, in exposome research with its classical orientation towards detrimental health effects of biological, chemical, and physical exposures, this knowledge remained underrepresented. But currently it gains great awareness and calls for innovations in rethinking the role of social environmental health determinants. To fill this gap that exists in terms of the social domain within exposome research, we propose a novel conceptual framework of the Social Exposome, to integrate the social environment in conjunction with the physical environment into the exposome concept. The iterative development process of the Social Exposome was based on a systematic compilation of social exposures in order to achieve a holistic portrayal of the human social environment - including social, psychosocial, socioeconomic, sociodemographic, local, regional, and cultural aspects, at individual and contextual levels. In order to move the Social Exposome beyond a mere compilation of exposures, three core principles are emphasized that underly the interplay of the multitude of exposures: Multidimensionality, Reciprocity, and Timing and continuity. The key focus of the conceptual framework of the Social Exposome is on understanding the underlying mechanisms that translate social exposures into health outcomes. In particular, insights from research on health equity and environmental justice have been incorporated to uncover how social inequalities in health emerge, are maintained, and systematically drive health outcomes. Three transmission pathways are presented: Embodiment, Resilience and Susceptibility or Vulnerability, and Empowerment. The Social Exposome conceptual framework may serve as a strategic map for, both, research and intervention planning, aiming to further explore the impact of the complex social environment and to alter transmission pathways to minimize health risks and health inequalities and to foster equity in health.

Societal Adaptation to Aging and Prevalence of Depression Among Older Adults: Evidence From 20 Countries

Policy Points Countries have adopted different strategies to support aging populations, which are broadly reflected in social, economic, and contextual environments. Referred to as "societal adaptation to aging," these factors affect countries' capacity to support older adults. Results from our study show that countries with more robust societal adaptation to aging had lower depression prevalence. Reductions in depression prevalence occurred among every investigated sociodemographic group and were most pronounced among the old-old. Findings suggest that societal factors have an underacknowledged role in shaping depression risk. Policies that improve societal approaches to aging may reduce depression prevalence among older adults.

CONTEXT

Countries have adopted various formal and informal approaches to support older adults, which are broadly reflected in different policies, programs, and social environments. These contextual environments, broadly referred to as "societal adaptation to aging," may affect population health.

METHODS

We used a new theory-based measure that captured societal adaptation to aging, the Aging Society Index (ASI), which we linked with harmonized individual-level data from 89,111 older adults from 20 countries. Using multi-levels models that accounted for differences in the population composition across countries, we estimated the association between country-level ASI scores and depression prevalence. We also tested if associations were stronger among the old-old and among sociodemographic groups that experience more disadvantage (i.e., women, those with lower educational attainment, unmarried adults).

FINDINGS

We found that countries with higher ASI scores, indicating more comprehensive approaches to supporting older adults, had lower depression prevalence. We found especially strong reductions in depression prevalence among the oldest adults in our sample. However, we did not find stronger reductions among sociodemographic groups who may experience more disadvantage.

CONCLUSIONS

Country-level strategies to support older adults may affect depression prevalence. Such strategies may become increasingly important as adults grow older. These results offer promising evidence that improvements in societal adaptation to aging-such as through adoption of more comprehensive policies and programs targeting older adults-may be one avenue to improve population mental health. Future research could investigate observed associations using longitudinal and quasi-experimental study designs, offering additional information regarding a potential causal relationship.

Personal recovery and socio-structural disadvantage: A critical conceptual review

Despite its seeming breadth and diversity, the bulk of the personal (mental health) recovery literature has remained strangely 'silent' about the impact of various socio-structural inequalities on the recovery process. Such an inadequacy of the empirical literature is not without consequences since the systematic omission or downplaying, at best, of the socio-structural conditions of living for persons with lived experience of mental health difficulties may inadvertently reinforce a reductionist view of recovery as an atomised, individualised phenomenon. Motivated by those limitations in extant scholarship, a critical literature review was conducted to identify and critique relevant research to problematise the notion of personal recovery in the context of socio-structural disadvantage such as poverty, homelessness, discrimination and inequalities. The review illuminates the scarcity of empirical research and the paucity of sociologically-informed theorisation regarding how recovery is shaped by the socio-structural conditions of living. Those inadequacies are especially pertinent to homelessness research, whereby empirical investigations of personal recovery have remained few and undertheorised. The gaps in the research and theorising about the relational, contextual and socio-structural embeddedness of recovery are distilled. The critical review concludes that personal recovery has remained underresearched, underproblematised and undertheorised, especially in the context of homelessness and other forms of socio-structural disadvantage. Understanding how exclusionary social arrangements affect individuals' recovery, and the coping strategies that they deploy to negotiate those, is likely to inform anti-oppressive interventions that could eventually remove the structural constraints to human emancipation and flourishing.

Action on the social determinants for advancing health equity in the time of COVID-19: perspectives of actors engaged in a WHO Special Initiative

Since the 2008 publication of the reports of the Commission on Social Determinants of Health and its nine knowledge networks, substantial research has been undertaken to document and describe health inequities. The COVID-19 pandemic has underscored the need for a deeper understanding of, and broader action on, the social determinants of health. Building on this unique and critical opportunity, the World Health Organization is steering a multi-country Initiative to reduce health inequities through an action-learning process in 'Pathfinder' countries. The Initiative aims to develop replicable and reliable models and practices that can be adopted by WHO offices and UN staff to address the social determinants of health to advance health equity. This paper provides an overview of the Initiative by describing its broad theory of change and work undertaken in three regions and six Pathfinder countries in its first year-and-a-half. Participants engaged in the Initiative describe results of early country dialogues and promising entry points for implementation that involve model, network and capacity building. The insights communicated through this note from the field will be of interest for others aiming to advance health equity through taking action on the social determinants of health, in particular as regards structural determinants.

Social Risk Factors Are Associated With Disability Prevalence - Results From 17 States in the 2017 Behavioral Risk Factor Surveillance System

PURPOSE

Determine the association between incremental increases in the number of social risk factors and the prevalence of any disability and disability type.

DESIGN

The cross-sectional analysis was conducted using 2017 Behavioral Risk Factor Surveillance System data from states whose surveys included items about social risk factors.

SETTING

Respondents from 17 US states.

SUBJECTS

Respondents included 136 432 adults.

MEASURES

Dichotomized social risk factors included food, housing, and financial insecurity, unsafe neighborhood, and healthcare access hardship.

ANALYSIS

Weighted χ² and logistic regression analyses adjusted for demographic characteristics, measures of socioeconomic position, and comorbid health conditions were used to examine differences in the prevalence of disability by social risk factor and via a social risk index created by summing the social risk factors.

RESULTS

Compared to those reporting 0 social risk factors, respondents reporting ≥4 had more than thrice the odds of reporting a cognition ((adjusted odds ratio [AOR]=3.37; 95%CI [2.75-4.13]), independent living (AOR=3.24 [2.52-4.15]), self-care (AOR=3.33 [2.55-4.34]), or any disability (AOR=3.90 [3.24-4.70]); more than twice the odds of reporting a vision (AOR=2.61 [1.93-3.52]) or mobility (AOR=2.72 [2.16-3.41]) disability; and more than 1.5 times the odds of reporting a hearing disability (AOR=1.59 [1.22-2.07]).

CONCLUSIONS

Incremental increases in the number of social risk factors were independently associated with higher odds of disability. Intervention efforts should address the social context of US adults with disabilities to improve health outcomes.

Authorship Distribution and Under-Representation of Sub-Saharan African Authors in Global Oncology Publications

Local researchers must be engaged in research conducted in their populations. However, local authors from low- and middle-income countries are often under-represented in global health journals. This report aims to assess and describe the representation of authors in the Journal of Clinical Oncology Global Oncology (JCO GO).

Sub-Saharan African authors are under-represented in global onc publications →* more equity is needed. *The authors would like to use an arrow emoji in their tweet.

Cross-sectional study of COVID-19 knowledge, beliefs and prevention behaviours among adults in Senegal

OBJECTIVES

The aim of the study was to explore COVID-19 beliefs and prevention behaviours in a francophone West African nation, Senegal.

DESIGN

This was a cross-sectional analysis of survey data collected via a multimodal observational study.

PARTICIPANTS

Senegalese adults aged 18 years or older (n=1452).

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome measures were COVID-19 prevention behaviours. Secondary outcome measures included COVID-19 knowledge and beliefs. Univariate, bivariate and multivariate statistics were generated to describe the sample and explore potential correlations.

SETTING

Participants from Senegal were recruited online and telephonically between June and August 2020.

RESULTS

Mask wearing, hand washing and use of hand sanitiser were most frequently reported. Social distancing and staying at home were also reported although to a lower degree. Knowledge and perceived risk of COVID-19 were very high in general, but risk was a stronger and more influential predictor of COVID-19 prevention behaviours. Men, compared with women, had lower odds (adjusted OR (aOR)=0.59, 95% CI 0.46 to 0.75, p<0.001) of reporting prevention behaviours. Rural residents (vs urban; aOR=1.49, 95% CI 1.12 to 1.98, p=0.001) and participants with at least a high school education (vs less than high school education; aOR=1.33, 95% CI 1.01 to 1.76, p=0.006) were more likely to report COVID-19 prevention behaviours.

CONCLUSIONS

In Senegal, we observed high compliance with recommended COVID-19 prevention behaviours among our sample of respondents, in particular for masking and personal hygiene practice. We also identified a range of psychosocial and demographic predictors for COVID-19 prevention behaviours such as knowledge and perceived risk. Stakeholders and decision makers in Senegal and across Africa can use place-based evidence like ours to address COVID-19 risk factors and intervene effectively with policies and programming. Use of both phone and online surveys enhances representation and study generalisability and should be considered in future research with hard-to-reach populations.

Enabling community input to improve equity in and access to translational research: The Community Coalition for Equity in Research

Background:

The COVID vaccine trials illustrated the critical need for the development of mechanisms to serve as a bridge between least advantaged communities and researchers. Such mechanisms would increase the number of studies that are designed with community needs and interests in mind, in ways that will close gaps rather than widen them. This paper reports on the creation of the Community Coalition for Equity in Research, a community-driven resource designed to build community capacity to provide researchers with credible and actionable input on study design and implementation and increase researchers’ understanding of factors that influence community support of research.

Methods and Results:

We provide a description of the Coalition’s structure and process and an evaluation of its first year of operation. Researchers rated their experience very positively and reported that the Coalition’s review will improve their research. Coalition members reported high levels of satisfaction with their participation and the processes set up for them to engage with researchers. Members also largely agreed that their participation has value for their community, and that it has increased their interest in research and the likelihood that they would recommend research participation to others.

Conclusions:

The Coalition represents a model for increasing two-way engagement between researchers and the larger community. We are optimistic that the Coalition will continue to develop and grow into a vibrant entity that will bring value to both investigators and our local communities and will increase the consideration of equity as a foundational principle in all translational research.

Individual Life-Course Socioeconomic Position and Hearing Aid Use in the Atherosclerosis Risk in Communities Study

BACKGROUND

To measure the association between individual life-course socioeconomic position (SEP) and hearing aid use, we examined childhood and adulthood socioeconomic variables collected at the Atherosclerosis Risk in Communities (ARIC) study baseline visit (1987-1989)/Life Course Socioeconomic Status study (2001-2002) and hearing aid use data collected at visit 6 (2016-2017).

METHODS

ARIC is a prospective cohort study of older adults (45-64 years) recruited from 4 U.S. communities. This analysis included a subset of 2 470 participants with hearing loss at visit 6 (≥25 decibels hearing level [dB HL] better-ear) with complete hearing aid use data. Childhood SEP variables included parental education, parental occupation, and parental home ownership. Young and older adulthood SEP variables included income, education, occupation, and home ownership. Each life epoch was assigned a score ranging from 0 to 5 and then summed to calculate the individual cumulative SEP score. Multivariable-adjusted logistic regression was used to estimate the association between individual cumulative SEP and hearing aid use. Missing SEP scores were imputed for participants with incomplete socioeconomic data.

RESULTS

Of the 2 470 participants in the analytic cohort (median [interquartile interval] age 79.9 [76.7-84.0], 1 330 [53.8%] women, 450 [18.2%] Black), 685 (27.7%) participants reported hearing aid use. Higher cumulative SEP was positively associated with hearing aid use (odds ratio [OR] = 1.09, 95% confidence interval [CI]: 1.04-1.14), and slightly stronger for childhood (OR = 1.09, 95% CI: 1.00-1.20) than older adulthood SEP score (OR = 1.06, 95% CI: 0.95-1.18).

CONCLUSIONS

In this community-based cohort of older adults with hearing loss, higher individual life-course SEP was positively associated with hearing aid use.

Active Ageing in Italy: An Evidence-Based Model to Provide Recommendations for Policy Making and Policy Implementation

In ageing societies, active ageing (AA) has been recognized as a useful conceptual tool due to its holistic approach to social issues and recognised benefits from it at multiple levels (micro, meso and macro) for addressing demographic challenges. However, one of the main problems identified in relation to AA, is to turn into practice, at the policy making level, the many positive aspects that it promises at the conceptual level, as is demonstrated by the available evidence based on experiences carried out in some European countries. As an advancement in this field, through an original research experience carried out in Italy between 2019 and 2021, this study for the first time provides a model for producing recommendations for policy making and policy implementation in the field of AA, by managing the main problematic aspects related to the operationalization, at the policy making level, of the AA concept, with the potential for replication in other countries. The main challenges were identified, as well as the way to deal with them through a model, for a proper operationalization of the AA concept, based, among other aspects, on a solid international framework concerning this matter, on a mainstreaming ageing approach (at the public policy level) and on a wide stakeholder participation through co-decisional tools. A multi-level (national-regional-local) perspective was adopted to consider cultural and geographical diversity, among other challenges.

Authorship trends in infectious diseases society of America affiliated journal articles conducted in low-income countries, 1998-2018

An increasing amount of infectious diseases research is conducted in low-income countries (LIC) given their high burden of disease; however, the contribution of LIC investigators as measured by authorship metrics, specifically to infectious diseases research, has not been thoroughly studied. We performed a literature search for primary research conducted either within LICs or using samples from LIC participants published between 1998-2017 in the Infectious Disease Society of America-affiliated journals Clinical Infectious Diseases, Journal of Infectious Diseases, and Open Forum Infectious Diseases. Primary outcomes included proportion of LIC-affiliated first and last authors (i.e. lead authors) per year and authorship trends over time. Secondary outcomes included proportion of LIC-affiliated authorship by geographic distribution and disease focus. Among 1308 publications identified, 50% had either a first or last LIC-affiliated author. Among these authors, 48% of LIC-affiliated first authors and 52% of LIC-affiliated last authors also reported a non-LIC institutional affiliation. While the absolute number of articles by LIC-affiliated lead authors increased over the 20-year period, the proportion of articles with LIC-affiliated lead authors decreased. There is a growing literature for infectious disease research conducted in LICs yet authorship trends in a small subset of these publications demonstrate a pronounced and worsening exclusion of LIC-affiliated investigators from publishing as lead authors.

Integrating Sex/Gender into Environmental Health Research: Development of a Conceptual Framework

There is a growing awareness about the need to comprehensively integrate sex and gender into health research in order to enhance the validity and significance of research results. An in-depth consideration of differential exposures and vulnerability is lacking, especially within environmental risk assessment. Thus, the interdisciplinary team of the collaborative research project INGER (integrating gender into environmental health research) aimed to develop a multidimensional sex/gender concept as a theoretically grounded starting point for the operationalization of sex and gender in quantitative (environmental) health research. The iterative development process was based on gender theoretical and health science approaches and was inspired by previously published concepts or models of sex- and gender-related dimensions. The INGER sex/gender concept fulfills the four theoretically established prerequisites for comprehensively investigating sex and gender aspects in population health research: multidimensionality, variety, embodiment, and intersectionality. The theoretical foundation of INGER's multidimensional sex/gender concept will be laid out, as well as recent sex/gender conceptualization developments in health sciences. In conclusion, by building upon the latest state of research of several disciplines, the conceptual framework will significantly contribute to integrating gender theoretical concepts into (environmental) health research, improving the validity of research and, thus, supporting the promotion of health equity in the long term.

A Review of Regulatory Frameworks Governing Biobanking in the Low and Middle Income Member Countries of BCNet

Biomedical research based on the sharing and use of ever larger volumes of samples and data is increasingly becoming an essential component of scientific discovery. The success of biobanking and genomic research is dependent on the broad sharing of resources for use by investigators. However, important ethical challenges need to be addressed for the sample and data sharing to be successful. Despite low- and middle-income countries (LMICs) carrying a higher burden of disease, biomedical research conducted to date has mainly focused on high-income countries. In order for LMICs to benefit from the advances in such research, normative documents (such as laws and guidelines) play a significant role in allowing LMIC projects to partake and be represented in global biomedical research. The administration and management of the ethical aspects of biobanking, including informed consent, are key components in ensuring that samples and data can legally and ethically be used and shared. As part of its support to the LMIC biobanks, the International Agency for Research on Cancer (IARC) established a biobank and population cohort building network (BCNet) in 2013 with the aims of providing support (including education and training) and facilitating the development and improvement of biobanking infrastructure in LMICs. A comparative analysis of the laws and guidelines in BCNet countries was completed to highlight some of the ethical and legal issues related to biobanking in LMICs and to identify examples of effective systems of governance already in operation.

Directing Research Toward Health Equity: a Health Equity Research Impact Assessment

Despite medical research advancements, inequities persist, as research has enhanced the health of some while leaving many communities untouched. Reforms are needed to direct research toward health equity, both during this pandemic and beyond. All research must currently pass scientific and ethical review processes, but neither may adequately examine a project's potential impact on inequities and local communities. Research stakeholders need practical tools to help review and examine any given study's impact on health equity. We articulate a health equity research impact assessment, which draws from existing research impact assessments and health disparities research measures and frameworks. We describe how this tool was developed and how it may be used by research reviewers, researchers, academic institutions, and funding agencies to elevate health equity in medical science.

Associations between depressive esymptoms and identity-specific social support among Black men who have sex with men (BMSM) in Baltimore City, Maryland

Introduction

Depression and other adverse mental health outcomes are prevalent among Black men who have sex with men (BMSM). Social support can be protective against symptoms of depression, the effects of which may be amplified by experiences of a shared social identity.

Methods

We explored the associations between BMSM-specific social support and depressive symptoms among a sample of 280 BMSM. We used chi-square and t-tests to examine bivariate associations between social support, depressive symptoms, and key correlates, and logistic regression to adjust the relationship between social support and depressive symptoms.

Results

Most participants reported high (43.2%) or moderate (41.8%) levels of BMSM-specific social support, 38% reported depressive symptoms, and 47.6% were living with HIV. Adjusting for socioeconomic and structural vulnerabilities, health, and involvement in the gay community, high social support was associated with a marginal decrease in the odds of depressive symptoms compared to low social support.

Conclusions

Results indicate that BMSM-specific social support is protective against depressive symptoms even in the context of other socioeconomic and structural vulnerabilities, suggesting that strengths-based interventions focused on building community and mutual support among BMSM may be valuable tools to prevent depression and promote positive mental health outcomes for members of this population.

Quantifying representativeness in randomized clinical trials using machine learning fairness metrics

OBJECTIVE

We help identify subpopulations underrepresented in randomized clinical trials (RCTs) cohorts with respect to national, community-based or health system target populations by formulating population representativeness of RCTs as a machine learning (ML) fairness problem, deriving new representation metrics, and deploying them in easy-to-understand interactive visualization tools.

MATERIALS AND METHODS

We represent RCT cohort enrollment as random binary classification fairness problems, and then show how ML fairness metrics based on enrollment fraction can be efficiently calculated using easily computed rates of subpopulations in RCT cohorts and target populations. We propose standardized versions of these metrics and deploy them in an interactive tool to analyze 3 RCTs with respect to type 2 diabetes and hypertension target populations in the National Health and Nutrition Examination Survey.

RESULTS

We demonstrate how the proposed metrics and associated statistics enable users to rapidly examine representativeness of all subpopulations in the RCT defined by a set of categorical traits (eg, gender, race, ethnicity, smoking status, and blood pressure) with respect to target populations.

DISCUSSION

The normalized metrics provide an intuitive standardized scale for evaluating representation across subgroups, which may have vastly different enrollment fractions and rates in RCT study cohorts. The metrics are beneficial complements to other approaches (eg, enrollment fractions) used to identify generalizability and health equity of RCTs.

CONCLUSION

By quantifying the gaps between RCT and target populations, the proposed methods can support generalizability evaluation of existing RCT cohorts. The interactive visualization tool can be readily applied to identified underrepresented subgroups with respect to any desired source or target populations.

Informing 'good' global health research partnerships: A scoping review of guiding principles

Background: Several sets of principles have been proposed to guide global health research partnerships and mitigate inequities inadvertently caused by them. The existence of multiple sets of principles poses a challenge for those seeking to critically engage with and develop their practice. Which of these is best to use, and why? To what extent, if any, is there agreement across proposed principles?

Objective: The objectives of this review were to: (1) identify and consolidate existing documents and principles to guide global health research partnerships; (2) identify areas of overlapping consensus, if any, regarding which principles are fundamental in these partnerships; (3) identify any lack of consensus in the literature on core principles to support these partnerships.

Methods: A scoping review was conducted to gather documents outlining ‘principles’ of good global health research partnerships. A broad search of academic databases to gather peerreviewed literature was conducted, complemented by a hand-search of key global health funding institutions for grey literature guidelines.

Results: Our search yielded nine sets of principles designed to guide and support global health research partnerships. No single principle recurred across all documents reviewed. Most frequently cited were concerns with mutual benefits between partners (n = 6) and equity (n = 4). Despite a lack of consistency in the inclusion and definition of principles, all sources highlighted principles that identified attention to fairness, equity, or justice as an integral part of good global health research partnerships.

Conclusions: Lack of consensus regarding how principles are defined suggests a need for further discussion on what global health researchers mean by ‘core’ principles. Research partnerships should seek to interpret the practical meanings and requirements of these principles through international consultation. Finally, a need exists for tools to assist with implementation of these principles to ensure their application in research practice.

Achieving Equitable Access to Medicines and Health Services: A COVID-19-time Recalled Matter

In the 21^st century, while some people seek to use artificial intelligence for health services delivery, others have to surrender their health rights to meet basic needs. The gradient in health has become more pronounced in the COVID-19 crisis considering discrepancies in disease prevalence, geographical accessibility, availability, affordability, quality/safety of health services, and human resources. Through PubMed, GoogleScholar, Scopus, WHO, OECD, and UN databases, the English documents and global statistics were collected. Determining the role of health equity-related factors and introducing mechanisms to maintain regional and international justice in health, specifically during the COVID-19 pandemic, were among the core concepts of this paper. Social determinants of health (SDH), interregional and intraregional bodies are the main drivers of discrimination in health services. Governments should relish chief health strategists' role in possessing legitimacy, accountability, direction, transparent performance, fairness, and good governance in one word. Improving health literacy and telemedicine, providing income support, and reforming insurance where needed, are other national mechanisms to amend inequity. Among interregional issues, what is concerning is the matter of sanctions on access to health services, which is against the Universal Declaration of Human Rights. Shortage of vital medications, ventilators, test kits, COVID-19 vaccines, pharmaceutical raw materials, foreign currency, decreased national currency value, purchasing power parity, and quality/safety of health services resulted from such oppression. The article also provides practical suggestions, paving the way for re-establishing global solidarity and developing health justice in deprived regions.

Values are not enough: qualitative study identifying critical elements for prioritization of health equity in health systems

Background

Health system policies and programs that reduce health inequities and improve health outcomes are essential to address unjust social gradients in health. Prioritization of health equity is fundamental to addressing health inequities but challenging to enact in health systems. Strategies are needed to support effective prioritization of health equity.

Methods

Following provincial policy recommendations to apply a health equity lens in all public health programs, we examined health equity prioritization within British Columbia health authorities during early implementation. We conducted semi-structured qualitative interviews and focus groups with 55 senior executives, public health directors, regional directors, and medical health officers from six health authorities and the Ministry of Health. We used an inductive constant comparative approach to analysis guided by complexity theory to determine critical elements for prioritization.

Results

We identified seven critical elements necessary for two fundamental shifts within health systems. 1) Prioritization through informal organization includes creating a systems value for health equity and engaging health equity champions. 2) Prioritization through formal organization requires explicit naming of health equity as a priority, designating resources for health equity, requiring health equity in decision making, building capacity and competency, and coordinating a comprehensive approach across levels of the health system and government.

Conclusions

Although creating a shared value for health equity is essential, health equity - underpinned by social justice - needs to be embedded at the structural level to support effective prioritization. Prioritization within government and ministries is necessary to facilitate prioritization at other levels. All levels within health systems should be accountable for explicitly including health equity in strategic plans and goals. Dedicated resources are needed for health equity initiatives including adequate resourcing of public health infrastructure, training, and hiring of staff with equity expertise to develop competencies and system capacity.

The effects of socioeconomic conditions on old-age mortality within shared disability pathways

Objective

How disability manifests itself in an individual is a highly complex process influenced by a wide range of individual and environmental factors. Its complexity makes the search for generalizable characteristics of the disablement process a challenging task. Consequentially, little is known about how the effect on other health outcomes such as life expectancy are modified after the onset of chronic ailments. In this paper we posit an alternative approach to generalize health trajectories of older people with disability and then analyze how socioeconomic conditions affect the longevity within these trajectory groups.

Methods

Individual level information about the first three successive onsets of chronic disability after age 50 is transformed into state-sequences. We extract trajectory groups based on onset time and the time spent in a certain state. Mortality hazards are then estimated with a Gompertz proportional hazards model to compare effects of different socioeconomic measures within the trajectory groups.

Results

Three distinct trajectory groups are identified, the mild (1), the early severe (2), and late severe (3) pathway. Estimates of the mortality analysis suggest that social inequalities in longevity are less pronounced after onset of old-age disability. We found a consistent survival prolonging effect for individuals who engage in daily activities (such as meeting with friends, walking) that ranged between 33.2% and 77.3%. The importance of other variables varies between trajectory groups.

Discussion

This study shows how health trajectories of individuals with disability can be generalized when information on the onset and severity of single conditions is available. Such an approach may help us to better predict health and care expenditures and help families and individuals with their personal care planning. The findings from the subsequent survival analysis suggest a substantial reduction of socioeconomic mortality differences after onset of old-age disability, which appears to be independent of its nature.

A novel conceptual model and heuristic tool to strengthen understanding and capacities for health inequalities research

BACKGROUND

Despite increasing evidence on health inequalities over the past decades, further efforts to strengthen capacities to produce research on this topic are still urgently needed to inform effective interventions aiming to address these inequalities. To strengthen these research capacities, an initial comprehensive understanding of the health inequalities research production process is vital. However, most existing research and models are focused on understanding the relationship between health inequalities research and policy, with less focus on the health inequalities research production process itself. Existing conceptual frameworks provide valuable, yet limited, advancements on this topic; for example, they lack the capacity to comprehensively explain the health (and more specifically the health inequalities) research production process at the local level, including the potential pathways, components and determinants as well as the dynamics that might be involved. This therefore reduces their ability to be empirically tested and to provide practical guidance on how to strengthen the health inequalities research process and research capacities in different settings. Several scholars have also highlighted the need for further understanding and guidance in this area to inform effective action.

METHODS

Through a critical review, we developed a novel conceptual model that integrates the social determinants of health and political economy perspectives to provide a comprehensive understanding of how health inequalities research and the related research capacities are likely to be produced (or inhibited) at local level.

RESULTS

Our model represents a global hypothesis on the fundamental processes involved, and can serve as a heuristic tool to guide local level assessments of the determinants, dynamics and relations that might be relevant to better understand the health inequalities research production process and the related research capacities.

CONCLUSIONS

This type of knowledge can assist researchers and decision-makers to identify any information gaps or barriers to be addressed, and establish new entry points to effectively strengthen these research capacities. This can lead to the production of a stronger evidence base, both locally and globally, which can be used to inform strategic efforts aimed at achieving health equity.

Intersectionality-based quantitative health research and sex/gender sensitivity: a scoping review

Background

The implementation of a theoretical intersectionality framework into quantitative data analyses is gaining increasing interest in health research. The substantive foundation of intersectionality was established in the U.S., based on the claim of black feminists to broaden the scope of contemporary gender studies by considering the intersection between sex/gender and race/ethnicity more firmly. The aim of our scoping review with particular emphasis on sex/gender was to assess how intersectionality-informed studies in epidemiological research considered different social dimensions in their multivariable and multivariate analyses.

Methods

Following the PRISMA Extension for Scoping Reviews (PRISMA-ScR), we conducted a literature review in PubMed. Three distinct health-related fields were brought into focus: diabetes representing a frequent chronic disease, smoking as a wide-spread behavioural health determinant and physical activity as a central target for health promotion. Initially, we compared which and how different social dimensions were accounted for and how inter-categorical and intersectionality-informed analyses were conducted. Further, we assessed sex/gender sensitivity by comparing operationalisation of sex/gender, how sex/gender theories were used and which central theoretical sex/gender concepts were referred to when aiming at explanation of (intersectional) sex/gender differences.

Results

Our results suggest, that intersectionality-based analyses within the three selected health-related fields are mainly conducted in the U.S. and focused on the intersection between sex/gender and race/ethnicity by using them jointly as subgrouping variables and as parts of interaction terms in regression analyses. Income and education as proxies for social class as well as age are mainly used for adjustment in quantitative analyses. Other approaches for calculating interactions (i.a. synergy-index, CART-analysis) are an exception. Even though sex/gender was considered in every included study and Gender was the most frequent theoretical sex/gender concept referred to when theoretically explaining sex/gender differences, it was exclusively operationalised as binary and solution-linked sex/gender variables were hardly considered in quantitative analyses.

Conclusion

The systematic integration of solution-linked variables indicating modifiable aspects of sex/gender-related living conditions and disadvantages could improve sex/gender sensitivity as part of intersectionality-based quantitative data analysis in health research.

Cataract Services are Leaving Widows Behind: Examples from National Cross-Sectional Surveys in Nigeria and Sri Lanka

The Sustainable Development Goals aim to leave no one behind. We explored the hypothesis that women without a living spouse—including those who are widowed, divorced, separated, and never married—are a vulnerable group being left behind by cataract services. Using national cross-sectional blindness surveys from Nigeria (2005–2007; n = 13,591) and Sri Lanka (2012–2014; n = 5779) we categorized women and men by marital status (married/not-married) and place of residence (urban/rural) concurrently. For each of the eight subgroups we calculated cataract blindness, cataract surgical coverage (CSC), and effective cataract surgical coverage (eCSC). Not-married women, who were predominantly widows, experienced disproportionate cataract blindness—in Nigeria they were 19% of the population yet represented 56% of those with cataract blindness; in Sri Lanka they were 18% of the population and accounted for 54% of those with cataract blindness. Not-married rural women fared worst in access to services—in Nigeria their CSC of 25.2% (95% confidence interval, CI 17.8–33.8%) was far lower than the best-off subgroup (married urban men, CSC 80.0% 95% CI 56.3–94.3); in Sri Lanka they also lagged behind (CSC 68.5% 95% CI 56.6–78.9 compared to 100% in the best-off subgroup). Service quality was also comparably poor for rural not-married women—eCSC was 8.9% (95% CI 4.5–15.4) in Nigeria and 37.0% (95% CI 26.0–49.1) in Sri Lanka. Women who are not married are a vulnerable group who experience poor access to cataract services and high cataract blindness. To “leave no one behind”, multi-faceted strategies are needed to address their needs.

Lifetime experiences of gender-based violence, depression and condom use among female sex workers in Cameroon

BACKGROUND

In general populations, consistent data highlight the relationships among violence, HIV risk behavior and depression; however, these patterns are not well understood among female sex workers (FSWs). We examined the relationship between FSWs' experiences with sexual violence and consistent condom use as a key HIV risk behavior and explored mental health as a potential mediator.

METHODS

In total, 2,165 FSWs were recruited via respondent-driven sampling in Cameroon in 2016. The women answered questions about violence, condom use and mental health.

RESULTS

Inconsistent condom use with clients was reported by 23.5% of participants (508/2,165). Lifetime sexual violence was prevalent with 33.0% (713/2,163) of participants. Almost 50% (1,067/2,143) of respondents had some level of depression. Sexual violence was significantly associated with inconsistent condom use (adjusted risk ratio (aRR) 1.4, 95% confidence interval (CI) (1.2-1.6)). Of FSWs with no depression, 24.9% (267/1,071) reported sexual violence, versus 56.1% (32/57) of respondents with severe depression (p < .01). Severe depression significantly increased risk of condomless sex (aRR 1.8, 95% CI (1.3-2.6)); in mediation analysis, both sexual violence and severe depression remained significant predictors of condomless sex (aRR 1.4, 95% CI (1.2, 1.6) and aRR 1.7, 95% CI (1.2-2.4), respectively). Depression did not mediate the relationship between sexual violence and condom use.

CONCLUSION

Sexual violence and depression are prevalent and independently associated with condom nonuse with clients among FSWs in Cameroon. Results highlight the need for interventions to address mental health as well as gender-based violence for FSWs.

Effects of community health worker interventions on socioeconomic inequities in maternal and newborn health in low-income and middle-income countries: a mixed-methods systematic review

Introduction

Community health worker (CHW) interventions are promoted to improve maternal and newborn health in low-income and middle-income countries. We reviewed the evidence on their effectiveness in reducing socioeconomic inequities in maternal and newborn health outcomes, how they achieve these effects, and contextual processes that shape these effects.

Methods

We conducted a mixed-methods systematic review of quantitative and qualitative studies published between 1996 and 2017 in Medline, Embase, Web of Science and Scopus databases. We included studies examining the effects of CHW interventions in low-income and middle-income countries on maternal and newborn health outcomes across socioeconomic groups (wealth, occupation, education, class, caste or tribe and religion). We then conducted a narrative synthesis of evidence.

Results

We identified 1919 articles, of which 22 met the inclusion criteria. CHWs facilitated four types of interventions: home visits, community-based groups, cash transfers or combinations of these. Four studies found that CHWs providing home visits or facilitating women’s groups had equitable coverage. Four others found that home visits and cash transfer interventions had inequitable coverage. Five studies reported equitable effects of CHW interventions on antenatal care, skilled birth attendance and/or essential newborn care. One study found that a CHW home visit intervention did not reduce wealth inequities in skilled birth attendance. A study of women’s groups reported greater reductions in neonatal mortality among lower compared with higher socioeconomic groups. Equity was most improved when CHWs had relevant support for assisting women to improve health practices and access health care within community contexts.

Conclusion

While current evidence remains limited, particularly for mortality, existing studies suggest that CHW interventions involving home visits, cash transfers, participatory women’s groups or multiple components can improve equity in maternal and newborn health. Future mixed-methods research should explore intervention strategies and contextual processes shaping such effects on equity to optimise these efforts.

The impact and importance of place on health for young people of Pasifika descent in Queensland, Australia: a qualitative study towards developing meaningful health equity indicators

Background

Health equity is a priority in the global sustainable development agenda. Available health equity indicators often focus on health outcomes, access to healthcare, risk factors and determinants such as income, education, and gender. Less attention has been given to other social determinants, including those related to place and ethnicity. Measures such as income, education, and gender, however, may not provide policy-makers with sufficient information to redress inequities. In this paper, we begin to develop health equity indicators for young Pasifika peoples in Logan, Queensland, Australia. While health data on Pasifika young people in Queensland is scant, available data suggests significant inequalities. The purpose of the study was to develop an understanding of the drivers of these disparities through the lens of the social determinants of health, to create health equity indicators.

Methods

Following meetings with community stakeholders to develop respectful and collaborative partnership processes, we took a youth participatory action research approach. Six peer researchers (3 male, 3 female) were recruited from the Logan area for the project. Following training, the peer researchers undertook 31 qualitative interviews with young Pasifika (16–24 years old). Data was manually analysed, coded and grouped into themes to develop the draft indicators. Interviews used the culturally appropriate Talanoa storytelling approach.

Results

Six key themes were identified from the interviews and were used to develop example indicators related to: spiritual and socio-cultural dimensions, place, access to culturally responsive services, economic and material dimensions and political dimensions. The results demonstrate health inequities experienced by Pasifika populations are strongly linked to place and their economic, social and cultural position.

Conclusions

This study emphasises the need to understand the multiplicity of place-based factors that interact in complex ways to shape health inequities for young Pasifika peoples. It highlights health equity indicators must go beyond healthcare services, outcomes and a limited number of objective determinants, to include a more holistic focus. Starting to measure health and wellbeing via the lens of the social determinants of health will help to identify where policy-makers and programmes can intervene to begin to more adequately address inequities.

Obstacles and opportunities for monitoring ethnicity-based inequalities in maternal health care: Lessons from Mexico

BACKGROUND

Monitoring and reducing inequalities in health care has become more relevant since the adoption of the Sustainable Development Goals (SDGs). The SDGs bring an opportunity to put the assessment of inequalities by ethnicity on the agenda of decision-makers. The objective of this qualitative study is to know how current monitoring is carried out and to identify what factors influence the process in order to incorporate indicators that allow the evaluation of inequalities by ethnicity.

METHODS

We conducted 17 semi-structured interviews with key informants from the health ministry, monitoring observatories, research centers, and international organizations, involved in maternal health care monitoring in Mexico. Our analysis was interpretative-phenomenological and focused on examining experiences about monitoring maternal health care in order to achieve a full picture of the current context in which it takes place and the factors that influence it.

RESULTS

The obstacles and opportunities pointed out from the participants emerge from the limitations or advantages associated with the accuracy of evaluation, availability of information and resources, and effective management and decision-making. Technicians, coordinators, researchers or decision-makers are not only aware of the inequalities but also of its importance. However, this does not lead to political decisions permitting an indicator to be developed for monitoring it. As for opportunities, the role of international organizations and their links with the countries is crucial to carry out monitoring, due to political and technical support.

CONCLUSIONS

The success of a monitoring system to help decision-makers reduce inequalities in health care depends not only on accurate evaluations but also on the context in which it is implemented. Understanding the operation, obstacles and opportunities for monitoring could be a key issue if the countries want to advance towards assessing inequalities and reducing health inequities with the aid of concrete policies and initiatives.

Racial and Ethnic Disparities in Provider-Related Barriers to Health Care for Children in California After the ACA

The aim of this study was to examine disparities in provider-related barriers to health care by race and ethnicity of children in California after the implementation of the Affordable Care Act (ACA). California Health Interview Survey child (0-11 years) survey data from 2014 to 2016 were used to conduct multivariable logistic regressions to estimate the odds of reporting any provider-related barrier, trouble finding a doctor, child’s health insurance not accepted by provider, and child not being accepted as a new patient. Compared with parents of non-Latino white children, parents of non-Latino black, Latino, Asian, and other/multiracial children were not more likely to report experiencing any of the 4 provider-related barrier measures. The associations between children’s race and ethnicity and parents’ reports of provider-related barriers were nonsignificant. Findings demonstrate that there are no significant racial/ethnic differences in provider-related barriers to health care for children in California in the post-ACA era.

Understanding intersections of social determinants of maternal healthcare utilization in Uttar Pradesh, India

OBJECTIVE

To explore intersections of social determinants of maternal healthcare utilization using the Classification and Regression Trees (CART) algorithm which is a machine-learning method used to construct prediction models.

METHODS

Institutional review board approval for this study was granted from Public Health Service-Ethical Review Board (PHS-ERB) and from the Health Ministry Screening Committee (HMSC) facilitated by Indian Council for Medical Research (ICMR). IRB review and approval for the current analyses was obtained from University of California, San Diego. Cross-sectional data were collected from women with children aged 0-11 months (n = 5,565) from rural households in 25 districts of Uttar Pradesh, India. Participants were surveyed on maternal healthcare utilization including registration of pregnancy (model-1), receipt of antenatal care (ANC) during pregnancy (model-2), and delivery at health facilities (model -3). Social determinants of health including wealth, social group, literacy, religion, and early age at marriage were captured during the survey. The Classification and Regression Tree (CART) algorithm was used to explore intersections of social determinants of healthcare utilization.

RESULTS

CART analyses highlight the intersections, particularly of wealth and literacy, in maternal healthcare utilization in Uttar Pradesh. Model-1 documents that women who are poorer, illiterate and Muslim are less likely to have their pregnancies registered (71.4% vs. 86.0% in the overall sample). Model-2 documents that poorer, illiterate women had the lowest ANC coverage (37.7% vs 45% in the overall sample). Model-3, developed for deliveries at health facilities, highlighted that illiterate and poor women have the lowest representation among facility deliveries (59.6% vs. 69% in the overall sample).

CONCLUSION

This paper explores the interactions between determinants of maternal healthcare utilization indicators. The findings in this paper highlights that the interaction of wealth and literacy can play a very strong role in accentuating or diminishing healthcare utilization among women. The study also reveals that religion and women's age at marriage also interact with wealth and literacy to create substantial disparities in utilization. The study provides insights into the effect of intersections of determinants, and highlights the importance of using a more nuanced understanding of the impact of co-occurring forms of marginalization to effectively tackle inequities in healthcare utilization.

Social Determinants of Health in the lives of urinary catheter users

OBJECTIVE

To identify the influence of social determinants of health on the life conditions of patients who use intermittent urinary catheters.

METHOD

This was a descriptive study conducted in a rehabilitation center with 243 neurogenic bladder patients who used clear intermittent urinary catheters. The study was carried out between March 2012 and October 2015, using interviews based on semi-structured instruments, and data analysis using descriptive statistics.

RESULTS

Most of the patients were men, between 16 and 64 years old, single, with an elementary education level, and a monthly household income of 2 to 3 minimum wages. The results show that the social determinants of health were related to socioeconomic, demographic, and health factors.

CONCLUSION

The findings indicate a complex relationship between social determinants of health and the life conditions of patients who use clean intermittent urinary catheters, presenting greater vulnerability related to some aspects of health conditions.

In Madagascar, Use Of Health Care Services Increased When Fees Were Removed: Lessons For Universal Health Coverage

Despite overwhelming burdens of disease, health care access in most developing countries is extremely low. As governments work toward achieving universal health coverage, evidence on appropriate interventions to expand access in rural populations is critical for informing policies. Using a combination of population and health system data, we evaluated the impact of two pilot fee exemption interventions in a rural area of Madagascar. We found that fewer than one-third of people in need of health care accessed treatment when point-of-service fees were in place. However, when fee exemptions were introduced for targeted medicines and services, the use of health care increased by 65 percent for all patients, 52 percent for children under age five, and over 25 percent for maternity consultations. These effects were sustained at an average direct cost of US$0.60 per patient. The pilot interventions can become a key element of universal health care in Madagascar with the support of external donors.

Reducing inequity of cataract blindness and vision impairment is a global priority, but where is the evidence?

Throughout the world, people who are socially or economically disadvantaged disproportionately experience blindness and vision impairment caused by cataract. Reducing vision loss from cataract and its unequal distribution must be a priority if the WHO's aim of 'universal eye health' is to be realised. To help achieve this, decision-makers and service planners need evidence on which strategies improve access to cataract services among disadvantaged populations, and under what circumstances. Unfortunately, despite many strategies to improve cataract services being implemented in recent decades, evidence of what works, for who and in what circumstances is not readily available. This paper summarises the extent of the evidence on interventions to reduce inequity of vision loss from cataract and makes suggestions for how the evidence base can be strengthened.

Accounting for equity considerations in cost-effectiveness analysis: a systematic review of rotavirus vaccine in low- and middle-income countries

Background

Cost-effectiveness analysis (CEA) is frequently used as an input for guiding priority setting in health. However, CEA seldom incorporates information about trade-offs between total health gains and equity impacts of interventions. This study investigates to what extent equity considerations have been taken into account in CEA in low- and middle-income countries (LMICs), using rotavirus vaccination as a case study.

Methods

Specific equity-related indicators for vaccination were first mapped to the Guidance on Priority Setting in Health Care (GPS-Health) checklist criteria. Economic evaluations of rotavirus vaccine in LMICs identified via a systematic review of the literature were assessed to explore the extent to which equity was considered in the research objectives and analysis, and whether it was reflected in the evaluation results.

Results

The mapping process resulted in 18 unique indicators. Under the 'disease and intervention' criteria, severity of illness was incorporated in 75% of the articles, age distribution of the disease in 70%, and presence of comorbidities in 5%. For the 'social groups' criteria, relative coverage reflecting wealth-based coverage inequality was taken into account in 30% of the articles, geographic location in 27%, household income level in 8%, and sex at birth in 5%. For the criteria of 'protection against the financial and social effects of ill health', age weighting was incorporated in 43% of the articles, societal perspective in 58%, caregiver's loss of productivity in 45%, and financial risk protection in 5%. Overall, some articles incorporated the indicators in their model inputs (20%) while the majority (80%) presented results (costs, health outcomes, or incremental cost-effectiveness ratios) differentiated according to the indicators. Critically, less than a fifth (17%) of articles incorporating indicators did so due to an explicit study objective related to capturing equity considerations. Most indicators were increasingly incorporated over time, with a notable exception of age-weighting of DALYs.

Conclusion

Integrating equity criteria in CEA can help policy-makers better understand the distributional impact of health interventions. This study illustrates how equity considerations are currently being incorporated within CEA of rotavirus vaccination and highlights the components of equity that have been used in studies in LMICs. Areas for further improvement are identified.

How do gender relations affect the working lives of close to community health service providers? Empirical research, a review and conceptual framework

Close-to-community (CTC) providers have been identified as a key cadre to progress universal health coverage and address inequities in health service provision due to their embedded position within communities. CTC providers both work within, and are subject to, the gender norms at community level but may also have the potential to alter them. This paper synthesises current evidence on gender and CTC providers and the services they deliver. This study uses a two-stage exploratory approach drawing upon qualitative research from the six countries (Bangladesh, Indonesia, Ethiopia, Kenya, Malawi, Mozambique) that were part of the REACHOUT consortium. This research took place from 2013 to 2014. This was followed by systematic review that took place from January-September 2017, using critical interpretive synthesis methodology. This review included 58 papers from the literature. The resulting findings from both stages informed the development of a conceptual framework. We present the holistic conceptual framework to show how gender roles and relations shape CTC provider experience at the individual, community, and health system levels. The evidence presented highlights the importance of safety and mobility at the community level. At the individual level, influence of family and intra-household dynamics are of importance. Important at the health systems level, are career progression and remuneration. We present suggestions for how the role of a CTC provider can, with the right support, be an empowering experience. Key priorities for policymakers to promote gender equity in this cadre include: safety and well-being, remuneration, and career progression opportunities. Gender roles and relations shape CTC provider experiences across multiple levels of the health system. To strengthen the equity and efficiency of CTC programmes gender dynamics should be considered by policymakers and implementers during both the conceptualisation and implementation of CTC programmes.

Economic evaluations of alcohol prevention interventions: Is the evidence sufficient? A review of methodological challenges

•

There are few economic evaluations of alcohol prevention interventions.

•

Consideration of impacts beyond an individual’s health in evaluations is limited.

•

No published studies using other priority-setting methods in the alcohol area.

•

Consideration of wider societal perspectives and health inequalities is minimal.

•

Including inter-sectoral costs and consequences in evaluations is challenging.

Public health interventions have unique characteristics compared to health technologies, which present additional challenges for economic evaluation (EE). High quality EEs that are able to address the particular methodological challenges are important for public health decision-makers. In England, they are even more pertinent given the transition of public health responsibilities in 2013 from the National Health Service to local government authorities where new agents are shaping policy decisions.

Addressing alcohol misuse is a globally prioritised public health issue. This article provides a systematic review of EE and priority-setting studies for interventions to prevent and reduce alcohol misuse published internationally over the past decade (2006–2016). This review appraises the EE and priority-setting evidence to establish whether it is sufficient to meet the informational needs of public health decision-makers.

619 studies were identified via database searches. 7 additional studies were identified via hand searching journals, grey literature and reference lists. 27 met inclusion criteria. Methods identified included cost-utility analysis (18), cost-effectiveness analysis (6), cost-benefit analysis (CBA) (1), cost-consequence analysis (CCA) (1) and return-on-investment (1). The review identified a lack of consideration of methodological challenges associated with evaluating public health interventions and limited use of methods such as CBA and CCA which have been recommended as potentially useful for EE in public health. No studies using other specific priority-setting tools were identified.

Strategies and governance to reduce health inequalities: evidences from a cross-European survey

BACKGROUND

The main objective of the paper is to identify the governance system related to policies to reduce health inequalities in the European regions. Considering the Action Spectrum of inequalities and the check list of health equity governance, we developed a survey in the framework of the AIR Project - Addressing Inequalities Intervention in Regions - was an European project funded by the Executive Agency of Health and Consumers.

METHODS

A web-based qualitative questionnaire was developed that collected information about practiced strategies to reduce health inequalities. In total 28 questionnaires from 28 different regions, related to 13countries, were suitable for the analysis.

RESULTS

Progress in health equity strategies at the national and regional levels has been made by countries such as France, Portugal, Poland, and Germany. On the other hand, Spain, Italy, and Belgium have a variable situation depending on the region. However, the results of the survey indicate that the governance system for health equity different in terms of commitment, resources and tools.

CONCLUSIONS

The survey highlights a weakness of governance system for the majority of countries in terms of evaluation actions and of impact of interventions in reducing inequalities, and the difficulties in having a clear and integrated vision between the national and regional levels.

Strengthening capacity to research the social determinants of health in low- and middle-income countries: lessons from the INTREC programme

BACKGROUND

The INDEPTH Training & Research Centres of Excellence (INTREC) collaboration developed a training programme to strengthen social determinants of health (SDH) research in low- and middle-income countries (LMICs). It was piloted among health- and demographic researchers from 9 countries in Africa and Asia. The programme followed a blended learning approach and was split into three consecutive teaching blocks over a 12-month period: 1) an online course of 7 video lectures and assignments on the theory of SDH research; 2) a 2-week qualitative and quantitative methods workshop; and 3) a 1-week data analysis workshop. This report aims to summarise the student evaluations of the pilot and to suggest key lessons for future approaches to strengthen SDH research capacity in LMICs.

METHODS

Semi-structured interviews and questionnaires with 24 students from 9 countries in Africa and Asia were used to evaluate each teaching block. Information was collected about the students' motivation and interest in studying SDH, any challenges they faced during the consecutive teaching blocks, and suggestions they had for future courses on SDH.

RESULTS

Of the 24 students who began the programme, 13 (54%) completed all training activities. The students recognised the need for such a course and its potential to improve their skills as health researchers. The main challenges with the online course were time management, prior knowledge and skills required to participate in the course, and the need to get feedback from teaching staff throughout the learning process. All students found the face-to-face workshops to be of high quality and value for their work, because they offered an opportunity to clarify SDH concepts taught during the online course and to gain practical research skills. After the final teaching block, students felt they had improved their data analysis skills and were better able to develop research proposals, scientific manuscripts, and policy briefs.

CONCLUSIONS

The INTREC programme has trained a promising cadre of health researchers who live and work in LMICs, which is an essential component of efforts to identify and reduce national and local level health inequities. Time management and technological issues were the greatest challenges, which can inform future attempts to strengthen research capacity on SDH.

Social inequality in health: revisiting moments and trends in 50 years of publication of RSP

This study describes the frequency and types of articles on social inequalities in health published in 50 years of the Revista de Saúde Pública, taking as reference some milestones that were used as guidelines to develop the research on this theme. Checking titles, keywords and abstracts or full texts, we identified 288 articles whose central or secondary focus was social inequalities in health. Corresponding to just 1.8% in the initial years, articles on social inequalities in health have represent 10.1% of the articles published in the last decade. The designs used were mainly cross-sectional (58.0%) and ecological (18.1%). The most analyzed themes were: food/nutrition (20.8%), mortality (13.5%), infectious diseases (10.1%), oral health (9.0%), and health services (8.7%). Articles focused on the analysis of racial inequalities in health amounted to 6.9%. Few articles monitored the trends of social inequalities in health, essential enterprise to assess and support interventions, and an even smaller number evaluated the impact of policies and programs on the reduction of social inequalities in health.

Inequality in cataract blindness and services: moving beyond unidimensional analyses of social position

OBJECTIVE

Inequalities in cataract blindness are well known, but data are rarely disaggregated to explore the combined effects of a range of axes describing social disadvantage. We examined inequalities in cataract blindness and services at the intersection of three social axes.

METHODS

Three dichotomous social variables (sex (male/female); place of residence (urban/rural); literacy (literate/illiterate)) from cross-sectional national blindness surveys in Pakistan (2001-2004; n=16 507) and Nigeria (2005-2007; n=13 591) were used to construct eight subgroups, with disadvantaged subgroups selected a priori (ie, women, rural dwellers, illiterate). In each data set, the social distribution of cataract blindness, cataract surgical coverage (CSC) and effective cataract surgical coverage (eCSC) were examined. Inequalities were assessed comparing the best-off and worst-off subgroups using rate differences and rate ratios (RRs). Logistic regression was used to assess cumulative effects of multiple disadvantage.

RESULTS

Disadvantaged subgroups experienced higher prevalence of cataract blindness, lower CSC and lower eCSC in both countries. A social gradient was present for CSC and eCSC, with coverage increasing as social position improved. Relative inequality in eCSC was approximately twice as high as CSC (Pakistan: eCSC RR 2.7 vs CSC RR 1.3; Nigeria: eCSC RR 8.7 vs CSC RR 4.1). Cumulative disadvantage was observed for all outcomes, deteriorating further with each additional axis along which disadvantage was experienced.

CONCLUSIONS

Each outcome tended to be worse with the addition of each layer of social disadvantage. Illiterate, rural women fared worst in both settings. Moving beyond unidimensional analyses of social position identified subgroups in most need; this permits a more nuanced response to addressing the inequitable distribution of cataract blindness.

Healthy Ageing: Raising Awareness of Inequalities, Determinants, and What Could Be Done to Improve Health Equity

PURPOSE OF THE STUDY

Social and scientific discourses on healthy ageing and on health equity are increasingly available, yet from a global perspective limited conceptual and analytical work connecting both has been published. This review was done to inform the WHO World Report on Ageing and Health and to inform and encourage further work addressing both healthy aging and equity.

DESIGN AND METHODS

We conducted an extensive literature review on the overlap between both topics, privileging publications from 2005 onward, from low-, middle-, and high-income countries. We also reviewed evidence generated around the WHO Commission on Social Determinants of Health, applicable to ageing and health across the life course.

RESULTS

Based on data from 194 countries, we highlight differences in older adults' health and consider three issues: First, multilevel factors that contribute to differences in healthy ageing, across contexts; second, policies or potential entry points for action that could serve to reduce unfair differences (health inequities); and third, new research areas to address the cause of persistent inequities and gaps in evidence on what can be done to increase healthy ageing and health equity.

IMPLICATIONS

Each of these areas warrant in depth analysis and synthesis, whereas this article presents an overview for further consideration and action.

Research on health equity in the SDG era: the urgent need for greater focus on implementation

BACKGROUND

The tremendous increase in knowledge on inequities in health and their drivers in recent decades has not been matched by improvements in health inequities themselves, or by systematic evidence of what works to reduce health inequities. Within health equity research there is a skew towards diagnostic studies in comparison to intervention studies showing evidence of how interventions can reduce disparities.

MAIN TEXT

The lack of sufficient specific evidence on how to implement specific policies and interventions in specific contexts to reduce health inequities creates policy confusion and partly explains the lack of progress on health inequities. In the field of research on equity in health, the time has come to stop focusing so much energy on prevalence and pathways, and instead shift to proposing and testing solutions. Four promising approaches to do so are implementation research, natural experimental policy studies, research on buy-in by policy-makers to action on health inequities, and geospatial analysis.

CONCLUSION

The case for action on social determinants and health inequities has well and truly been made. The community of researchers on health equity now need to turn their attention to supporting implementation efforts towards achievements of the Sustainable Development Goals and substantive reductions in health inequities.

Disparities at the intersection of marginalized groups

PURPOSE

Mental health disparities exist across several dimensions of social inequality, including race/ethnicity, socioeconomic status and gender. Most investigations of health disparities focus on one dimension. Recent calls by researchers argue for studying persons who are marginalized in multiple ways, often from the perspective of intersectionality, a theoretical framework applied to qualitative studies in law, sociology, and psychology. Quantitative adaptations are emerging but there is little guidance as to what measures or methods are helpful.

METHODS

Here, we consider the concept of a joint disparity and its composition, show that this approach can illuminate how outcomes are patterned for social groups that are marginalized across multiple axes of social inequality, and compare the insights gained with that of other measures of additive interaction. We apply these methods to a cohort of young men from the National Longitudinal Survey of Youth, examining disparities for black men with low early life SES vs. white men with high early life SES across several outcomes that predict mental health, including unemployment, wages, and incarceration.

RESULTS AND CONCLUSIONS

We report striking disparities in each outcome, but show that the contribution of race, SES, and their intersection varies.

Socio-economic inequalities in health and health service use among older adults in India: results from the WHO Study on Global AGEing and adult health survey

OBJECTIVE

The objectives of this study were to measure socio-economic inequalities in self-reported health (SRH) and healthcare visits and to identify factors contributing to health inequalities among older people aged 50-plus years.

STUDY DESIGN

This study is based on a population-based, cross-sectional survey.

METHODS

We accessed data of 7150 older adults from the World Health Organization's Study on Global AGEing and adult health Indian survey. We used multivariate logistic regression to assess the correlates of poor SRH. We estimated the concentration index to measure socio-economic inequalities in SRH and healthcare visits. Regression-based decomposition analysis was employed to explore the correlates contributing to poor SRH inequality.

RESULTS

About 19% (95% CI: 18%, 20%) reported poor health (n = 1368) and these individuals were significantly less wealthy. In total, 5134 (71.8%) participants made at least one health service visit. Increasing age, female gender, low social caste, rural residence, multimorbidity, absence of pension support, and health insurance were significant correlates of poor SRH. The standardized concentration index of poor SRH -0.122 (95% CI: -0.102; -0.141) and healthcare visits 0.364 (95% CI: 0.324, 0.403) indicated pro-poor and pro-rich inequality, respectively. Economic status (62.3%), pension support (11.5%), health insurance coverage (11.5%), social caste (10.7%) and place of residence (4.1%) were important contributors to inequalities in poor health.

CONCLUSION

Socio-economic disparities in health and health care are major concerns in India. Achievement of health equity demand strategies beyond health policies, to include pro-poor, social welfare policies among older Indians.

An argument for renewed focus on epidemiology for public health

PURPOSE

Although epidemiology has an indispensable role in serving public health, the relative emphasis of applications of epidemiology often tend toward individual-level medicine over public health in terms of resources and impact.

METHODS

We make distinctions between public health and medical applications of epidemiology to raise awareness among epidemiologists, many of whom came to the field with public health in mind. We discuss reasons for the overemphasis on medical epidemiology and suggest ways to counteract these incentives.

RESULTS

Public health epidemiology informs interventions that are applied to populations or that confer benefits beyond the individual, whereas medical epidemiology informs interventions that improve the health of treated individuals. Available resources, new biomedical technologies, and existing epidemiologic methods favor medical applications of epidemiology. Focus on public health impact and methods suited to answer public health questions can create better balance and promote population-level improvements in public health.

CONCLUSIONS

By deliberately reflecting on research motivations and long-term goals, we hope the distinctions presented here will facilitate critical discussion and a greater consciousness of our potential impact on both individual and population-level health. Renewed intentions towards public health can help epidemiologists navigate potential projects and ultimately contribute to an epidemiology of consequence.

Large-scale fortification of condiments and seasonings as a public health strategy: equity considerations for implementation

Fortification of staple foods with vitamins and minerals is an effective approach to increase micronutrient intake and improve nutritional status. The specific use of condiments and seasonings as vehicles in large-scale fortification programs is a relatively new public health strategy. This paper underscores equity considerations for the implementation of large-scale fortification of condiments and seasonings as a public health strategy by examining nonexhaustive examples of programmatic experiences and pilot projects in various settings. An overview of conceptual elements in implementation research and equity is presented, followed by an examination of equity considerations for five implementation strategies: (1) enhancing the capabilities of the public sector, (2) improving the performance of implementing agencies, (3) strengthening the capabilities and performance of frontline workers, (3) empowering communities and individuals, and (4) supporting multiple stakeholders engaged in improving health. Finally, specific considerations related to intersectoral action are considered. Large-scale fortification of condiments and seasonings cannot be a standalone strategy and needs to be implemented with concurrent and coordinated public health strategies, which should be informed by a health equity lens.
