Risk of ESRD in the United States

BACKGROUND

Although incidence rates of end-stage renal disease (ESRD) in the United States are reported routinely by the US Renal Data System (USRDS), risks (probabilities) are not reported. Short- and long-term risk estimates need to be updated and expanded to minority populations, including Native Americans, Asian/Pacific Islanders, and Hispanics.

STUDY DESIGN

Risk estimation from surveillance data in large populations using life-table methods. A competing-risks framework was applied by constructing a hypothetical cohort followed from birth to death.

SETTING & PARTICIPANTS

Total US population. Incidence and mortality rates of ESRD were obtained from the USRDS; all-cause mortality rates were obtained from CDC WONDER.

PREDICTORS

Age, sex, race/ethnicity, and year.

OUTCOMES

10-year to lifetime risks (cumulative incidence) of ESRD.

RESULTS

Among males, lifetime risks of ESRD from birth using 2013 data were 3.1% (95% CI, 3.0%-3.1%) for non-Hispanic whites, 8.0% (95% CI, 7.9%-8.2%) for non-Hispanic blacks, 3.8% (95% CI, 3.4%-4.9%) for non-Hispanic Native Americans, 5.1% (95% CI, 4.8%-5.4%) for non-Hispanic Asians/Pacific Islanders, and 6.2% (95% CI, 6.1%-6.4%) for Hispanics. Among females, lifetime risks were 2.0% (95% CI, 2.0%-2.1%) for non-Hispanic whites, 6.8% (95% CI, 6.7%-6.9%) for non-Hispanic blacks, 3.6% (95% CI, 3.3%-4.2%) for non-Hispanic Native Americans, 3.8% (95% CI, 3.6%-4.0%) for non-Hispanic Asian/Pacific Islanders, and 4.3% (95% CI, 4.2%-4.5%) for Hispanics. Lifetime risk of ESRD from birth increased from 3.5% in 2000 to 4.0% in 2013 in males and decreased from 3.0% to 2.8% in females.

LIMITATIONS

Standard life-time assumption of fixed age-specific rates over time and possible ESRD misclassification. To be useful in clinical practice, this application will require additional predictors (eg, comorbid conditions and chronic kidney disease stage).

CONCLUSIONS

ESRD risk in the United States varies more than 2-fold among racial/ethnic groups for both sexes.

Trends in Between-Country Health Equity in Sub-Saharan Africa from 1990 to 2011: Improvement, Convergence and Reversal

It is not clear whether between-country health inequity in Sub-Saharan Africa has been reduced over time due to economic development and increased foreign investments. We used the World Health Organization's data about 46 nations in Sub-Saharan Africa to test if under-5 mortality rate (U5MR) and life expectancy (LE) converged or diverged from 1990 to 2011. We explored whether the standard deviation of selected health indicators decreased over time (i.e., sigma convergence), and whether the less developed countries moved toward the average level in the group (i.e., beta convergence). The variation of U5MR between countries became smaller from 1990 to 2001. Yet this sigma convergence trend did not continue after 2002. Life expectancy in Africa from 1990-2011 demonstrated a consistent convergence trend, even after controlling for initial differences of country-level factors. The lack of consistent convergence in U5MR partially resulted from the fact that countries with higher U5MR in 1990 eventually performed better than those countries with lower U5MRs in 1990, constituting a reversal in between-country health inequity. Thus, international aid agencies might consider to reassess the funding priority about which countries to invest in, especially in the field of early childhood health.

Scoping review: national monitoring frameworks for social determinants of health and health equity

BACKGROUND

The strategic importance of monitoring social determinants of health (SDH) and health equity and inequity has been a central focus in global discussions around the 2011 Rio Political Declaration on SDH and the Millennium Development Goals. This study is part of the World Health Organization (WHO) equity-oriented analysis of linkages between health and other sectors (EQuAL) project, which aims to define a framework for monitoring SDH and health equity.

OBJECTIVES

This review provides a global summary and analysis of the domains and indicators that have been used in recent studies covering the SDH. These studies are considered here within the context of indicators proposed by the WHO EQuAL project. The objectives are as follows: to describe the range of international and national studies and the types of indicators most frequently used; report how they are used in causal explanation of the SDH; and identify key priorities and challenges reported in current research for national monitoring of the SDH.

DESIGN

We conducted a scoping review of published SDH studies in the PubMed(®) database to obtain evidence of socio-economic indicators. We evaluated, selected, and extracted data from national scale studies published from 2004 to 2014. The research included papers published in English, Italian, French, Portuguese, and Spanish.

RESULTS

The final sample consisted of 96 articles. SDH monitoring is well reported in the scientific literature independent of the economic level of the country and magnitude of deprivation in population groups. The research methods were mostly quantitative and many papers used multilevel and multivariable statistical analyses and indexes to measure health inequalities and SDH. In addition to the usual economic indicators, a high number of socio-economic indicators were used. The indicators covered a broad range of social dimensions, which were given consideration within and across different social groups. Many indicators included in the WHO EQuAL framework were not common in the studies in this review due to their intersectoral and interdisciplinary nature.

CONCLUSIONS

Our review illustrates that the attention to SDH monitoring has grown in terms of its importance and complexity within the scientific health literature. We identified a need to make indicators more wide-ranging in order to include a broader range of social conditions. The WHO EQuAL framework can provide intersectoral and interdisciplinary means of building a more comprehensive standardised approach to monitoring the SDH and improving equity in health.

Analysing implementer narratives on addressing health inequity through convergent action on the social determinants of health in India

BACKGROUND

Understanding health inequity in India is a challenge, given the complexity that characterise the lives of its residents. Interpreting constructive action to address health inequity in the country is rare, though much exhorted by the global research community. We critically analysed operational understandings of inequity embedded in convergent actions to address health-related inequalities by stakeholders in varying contexts within the country.

METHODS

Two implementer groups were purposively chosen to reflect on their experiences addressing inequalities in health (and its determinants) in the public sector working in rural areas and in the private non-profit sector working in urban areas. A representing co-author from each group developed narratives around how they operationally defined, monitored, and addressed health inequality in their work. These narratives were content analysed by two other co-authors to draw out common and disparate themes characterising each action context, operational definitions, shifts and changes in strategies and definitions, and outcomes (both intended and unintended). Findings were reviewed by all authors to develop case studies.

RESULTS

We theorised that action to address health inequality converges around a unifying theme or pivot, and developed a heuristic that describes the features of this convergence. In one case, the convergence was a single decision-making platform for deliberation around myriad village development issues, while in the other, convergence brought together communities, legal, police, and health system action around one salient health issue. One case emphasized demand generation, the other was focussed on improving quality and supply of services. In both cases, the operationalization of equity broke beyond a biomedical or clinical focus. Dearth of data meant that implementers exercised various strategies to gather it, and to develop interventions - always around a core issue or population.

CONCLUSIONS

This exercise demonstrated the possibility of constructive engagement between implementers and researchers to understand and theorize action on health equity and the social determinants of health. This heuristic developed may be of use not just for further research, but also for on-going appraisal and design of policy and praxis, both sensitive to and reflective of Indian concerns and understandings.

Determinants of marginalization and inequitable maternal health care in North-Central Vietnam: a framework analysis

BACKGROUND

Vietnam has achieved great improvements in maternal healthcare outcomes, but there is evidence of increasing inequity. Disadvantaged groups, predominantly ethnic minorities and people living in remote mountainous areas, do not gain access to maternal health improvements despite targeted efforts from policymakers.

OBJECTIVE

This study identifies underlying structural barriers to equitable maternal health care in Nghe An province, Vietnam. Experiences of social inequity and limited access among child-bearing ethnic and minority women are explored in relation to barriers of care provision experienced by maternal health professionals to gain deeper understanding on health outcomes.

DESIGN

In 2012, 11 focus group discussions with women and medical care professionals at local community health centers and district hospitals were conducted using a hermeneutic-dialectic method and analyzed for interpretation using framework analysis.

RESULTS

The social determinants 'limited negotiation power' and 'limited autonomy' orchestrate cyclical effects of shared marginalization for both women and care professionals within the provincial health system's infrastructure. Under-staffed and poorly equipped community health facilities refer women and create overload at receiving health centers. Limited resources appear diverted away from local community centers as compensation to the district for overloaded facilities. Poor reputation for low care quality exists, and professionals are held in low repute for causing overload and resulting adverse outcomes. Country-wide reforms force women to bear responsibility for limited treatment adherence and health insight, but overlook providers' limited professional development. Ethnic minority women are hindered by relatives from accessing care choices and costs, despite having advanced insight about government reforms to alleviate poverty. Communication challenges are worsened by non-existent interpretation systems.

CONCLUSIONS

For maternal health policy outcomes to become effective, it is important to understand that limited negotiation power and limited autonomy simultaneously confront childbearing women and health professionals. These two determinants underlie the inequitable economic, social, and political forces in Vietnam's disadvantaged communities, and result in marginalized status shared by both in the poorest sectors.

Impacts of Climate Change on Inequities in Child Health

This paper addresses an often overlooked aspect of climate change impacts on child health: the amplification of existing child health inequities by climate change. Although the effects of climate change on child health will likely be negative, the distribution of these impacts across populations will be uneven. The burden of climate change-related ill-health will fall heavily on the world's poorest and socially-disadvantaged children, who already have poor survival rates and low life expectancies due to issues including poverty, endemic disease, undernutrition, inadequate living conditions and socio-economic disadvantage. Climate change will exacerbate these existing inequities to disproportionately affect disadvantaged children. We discuss heat stress, extreme weather events, vector-borne diseases and undernutrition as exemplars of the complex interactions between climate change and inequities in child health.

Diabetes and work: 12-year national follow-up study of the association of diabetes incidence with socioeconomic group, age, gender and country of origin

AIMS

To investigate the extent and socioeconomic distribution of incident diabetes among the Danish working-age population.

METHODS

The Danish National Diabetes Register was linked with socioeconomic and population-based registers covering the entire population. We analysed the 12-year diabetes incidence using multivariate Poisson regression for 2,086,682 people, adjusting for gender, 10-year age groups, main population groups defined by country of origin, and seven socioeconomic groups: professionals, managers, technicians, workers skilled at basic level, unskilled workers, unemployed and pensioners.

RESULTS

The crude 12-year incidence of diabetes was 5.8%. The saturated multivariate model, adjusted for gender, age, country of origin and socioeconomic status; showed a relative risk (RR) for diabetes incidence of 1.44 for male (reference: female), 3.95 for the age range of 50-59 years (reference: 30-39 years), 2.07 for unskilled workers (reference: professionals) and 2.15 for people from countries of 'non-Western origin' (reference: Danish origin).

CONCLUSIONS

Diabetes incidence increases with age, male gender and low socioeconomic status; and also among people from countries of 'non-Western origin'. The results indicate that getting a more senior workforce will substantially increase the proportion of workers with diabetes, especially among already vulnerable groups.

Community health workers as an integral strategy in the REACH U.S. program to eliminate health inequities

Mounting evidence indicates that community health workers (CHWs) contribute to improved behavioral and health outcomes and reductions in health disparities. We provide an overview (based on grantee reports and community action plans) that describe CHW contributions to 22 Racial and Ethnic Approaches to Community Health (REACH) programs funded by the Centers for Disease Control and Prevention from 2007 to 2012, offering additional evidence of their contributions to the effectiveness of community public health programs. We then highlight how CHWs helped deliver REACH U.S. community interventions to meet differing needs across communities to bridge the gap between health care services and community members, build community and individual capacity to plan and implement interventions addressing multiple chronic health conditions, and meet community needs in a culturally appropriate manner. The experience, skills, and success gained by CHWs participating in the REACH U.S. program have fostered important individual community-level changes geared to increase health equity. Finally, we underscore the importance of CHWs being embedded within these communities and the flexibility they offer to intervention strategies, both of which are characteristics critical to meeting needs of communities experiencing health disparities. CHWs served a vital role in facilitating and leading changes and will continue to do so.

Maternal and institutional characteristics associated with the administration of prophylactic antibiotics for caesarean section: a secondary analysis of the World Health Organization Multicountry Survey on Maternal and Newborn Health

OBJECTIVE

To illustrate the variability in the use of antibiotic prophylaxis for caesarean section, and its effect on the prevention of postoperative infections.

DESIGN

Secondary analysis of a cross-sectional study.

SETTING

Twenty-nine countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health.

POPULATION

Three hundred and fifty-nine health facilities with the capacity to perform caesarean section.

METHODS

Descriptive analysis and effect estimates using multilevel logistic regression.

MAIN OUTCOME MEASURES

Coverage of antibiotic prophylaxis for caesarean section.

RESULTS

A total of 89 121 caesarean sections were performed in 332 of the 359 facilities included in the survey; 87% under prophylactic antibiotic coverage. Thirty five facilities provided 0-49% coverage and 77 facilities provided 50-89% coverage. Institutional coverage of prophylactic antibiotics varied greatly within most countries, and was related to guideline use and the practice of clinical audits, but not to the size, location of the institution or development index of the country. Mothers with complications, such as HIV infection, anaemia, or pre-eclampsia/eclampsia, were more likely to receive antibiotic prophylaxis. At the same time, mothers undergoing caesarean birth prior to labour and those with indication for scheduled deliveries were also more likely to receive antibiotic prophylaxis, despite their lower risk of infection, compared with mothers undergoing emergency caesarean section.

CONCLUSIONS

Coverage of antibiotic prophylaxis for caesarean birth may be related to the perception of the importance of guidelines and clinical audits in the facility. There may also be a tendency to use antibiotics when caesarean section has been scheduled and antibiotic prophylaxis is already included in the routine clinical protocol. This study may act as a signal to re-evaluate institutional practices as a way to identify areas where improvement is possible.

Socio-economic determinants and inequities in coverage and timeliness of early childhood immunisation in rural Ghana

OBJECTIVES

To assess the extent of socio-economic inequity in coverage and timeliness of key childhood immunisations in Ghana.

METHODS

Secondary analysis of vaccination card data collected from babies born between January 2008 and January 2010 who were registered in the surveillance system supporting the ObaapaVita and Newhints Trials was carried out. 20 251 babies had 6 weeks' follow-up, 16 652 had 26 weeks' follow-up, and 5568 had 1 year's follow-up. We performed a descriptive analysis of coverage and timeliness of vaccinations by indicators for urban/rural status, wealth and educational attainment. The association of coverage with socio-economic indicators was tested using a chi-square-test and the association with timeliness using Cox regression.

RESULTS

Overall coverage at 1 year of age was high (>95%) for Bacillus Calmette-Guérin (BCG), all three pentavalent diphtheria-pertussis-tetanus-haemophilus influenzae B-hepatitis B (DPTHH) doses and all polio doses except polio at birth (63%). Coverage against measles and yellow fever was 85%. Median delay for BCG was 1.7 weeks. For polio at birth, the median delay was 5 days; all other vaccine doses had median delays of 2-4 weeks. We found substantial health inequity across all socio-economic indicators for all vaccines in terms of timeliness, but not coverage at 1 year. For example, for the last DPTHH dose, the proportion of children delayed more than 8 weeks were 27% for urban children and 31% for rural children (P < 0.001), 21% in the wealthiest quintile and 41% in the poorest quintile (P < 0.001), and 9% in the most educated group and 39% in the least educated group (P < 0.001). However, 1-year coverage of the same dose remained above 90% for all levels of all socio-economic indicators.

CONCLUSIONS

Ghana has substantial health inequity across urban/rural, socio-economic and educational divides. While overall coverage was high, most vaccines suffered from poor timeliness. We suggest that countries achieving high coverage should include timeliness indicators in their surveillance systems.

Inequalities in public health care delivery in Zambia

BACKGROUND

Access to adequate health services that is of acceptable quality is important in the move towards universal health coverage. However, previous studies have revealed inequities in health care utilisation in the favour of the rich. Further, those with the greatest need for health services are not getting a fair share. In Zambia, though equity in access is extolled in government documents, there is evidence suggesting that those needing health services are not receiving their fair share. This study seeks therefore, to assess if socioeconomic related inequalities/inequities in public health service utilisation in Zambia still persist.

METHODS

The 2010 nationally representative Zambia Living Conditions and Monitoring Survey data are used. Inequality is assessed using concentration curves and concentrations indices while inequity is assessed using a horizontal equity index: an index of inequity across socioeconomic status groups, based on standardizing health service utilisation for health care need. Public health services considered include public health post visits, public clinic visits, public hospital visits and total public facility visits.

RESULTS

There is evidence of pro-poor inequality in public primary health care utilisation but a pro-rich inequality in hospital visits. The concentration indices for public health post visits and public clinic visits are -0.28 and -0.09 respectively while that of public hospitals is 0.06. After controlling for need, the pro-poor distribution is maintained at primary facilities and with a pro-rich distribution at hospitals. The horizontal equity indices for health post and clinic are estimated at -0.23 and -0.04 respectively while that of public hospitals is estimated at 0.11. A pro-rich inequity is observed when all the public facilities are combined (horizontal equity index = 0.01) though statistically insignificant.

CONCLUSION

The results of the paper point to areas of focus in ensuring equitable access to health services especially for the poor and needy. This includes strengthening primary facilities that serve the poor and reducing access barriers to ensure that health care utilisation at higher-level facilities is distributed in accordance with need for it. These initiatives may well reduce the observed inequities and accelerate the move towards universal health coverage in Zambia.

Simple steps to equity in child survival

Although the number of child deaths has declined globally over the past 20 years, many countries still lag behind their millennium development goal targets, and inequity in child health remains a pernicious problem both between and within countries. Breastfeeding is a key intervention to reduce child mortality, and in an article published in BMC Medicine, Roberts and colleagues have shown that breastfeeding interventions can have a significant role in reducing inequity in child health. With the proper attention paid to overcoming the barriers to scaling up breastfeeding interventions, deployment of effective interventions in health facilities and the community, and improvements in support for breastfeeding interventions across society, many countries that are struggling to meet their millennium development goals could make significant gains in child survival and inequity.

Can breastfeeding promote child health equity? A comprehensive analysis of breastfeeding patterns across the developing world and what we can learn from them

BACKGROUND

In 2010 more than 7.7 million children died before their fifth birthday. Over 98% of these deaths occurred in developing countries, and recent estimates have attributed hundreds of thousands of these deaths to suboptimal breastfeeding.

METHODS

This study estimated prevalence of suboptimal breastfeeding for 137 developing countries from 1990 to 2010. These estimates were compared against WHO infant feeding recommendations and combined with effect sizes from existing literature to estimate associated disease burden using a standard comparative risk assessment approach. These prevalence estimates were disaggregated by wealth quintile and linked with child mortality rates to assess how improved rates of breastfeeding may affect child health inequalities.

RESULTS

In 2010, the prevalence of exclusive breastfeeding ranged from 3.5% in Djibouti to 77.3% in Rwanda. The proportion of child Disability Adjusted Life Years (DALYs) attributable to suboptimal breastfeeding is 7.6% at the global level and as high as 20.2% in Swaziland. Suboptimal breastfeeding is a leading childhood risk factor in all developing countries and consistently ranks higher than water and sanitation. Within most countries, breastfeeding prevalence rates do not vary considerably across wealth quintiles.

CONCLUSIONS

Breastfeeding is an effective child health intervention that does not require extensive health system infrastructure. Improvements in rates of exclusive and continued breastfeeding can contribute to the reduction of child mortality inequalities in developing countries.

A new generation of trade policy: potential risks to diet-related health from the trans pacific partnership agreement

Trade poses risks and opportunities to public health nutrition. This paper discusses the potential food-related public health risks of a radical new kind of trade agreement: the Trans Pacific Partnership agreement (TPP). Under negotiation since 2010, the TPP involves Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the USA, and Vietnam. Here, we review the international evidence on the relationships between trade agreements and diet-related health and, where available, documents and leaked text from the TPP negotiations. Similar to other recent bilateral or regional trade agreements, we find that the TPP would propose tariffs reductions, foreign investment liberalisation and intellectual property protection that extend beyond provisions in the multilateral World Trade Organization agreements. The TPP is also likely to include strong investor protections, introducing major changes to domestic regulatory regimes to enable greater industry involvement in policy making and new avenues for appeal. Transnational food corporations would be able to sue governments if they try to introduce health policies that food companies claim violate their privileges in the TPP; even the potential threat of litigation could greatly curb governments' ability to protect public health. Hence, we find that the TPP, emblematic of a new generation of 21st century trade policy, could potentially yield greater risks to health than prior trade agreements. Because the text of the TPP is secret until the countries involved commit to the agreement, it is essential for public health concerns to be articulated during the negotiation process. Unless the potential health consequences of each part of the text are fully examined and taken into account, and binding language is incorporated in the TPP to safeguard regulatory policy space for health, the TPP could be detrimental to public health nutrition. Health advocates and health-related policymakers must be proactive in their engagement with the trade negotiations.

Health professionals working with First Nations, Inuit, and Métis consensus guideline

OBJECTIVE

Our aim is to provide health care professionals in Canada with the knowledge and tools to provide culturally safe care to First Nations, Inuit, and Métis women and through them, to their families, in order to improve the health of First Nations, Inuit, and Métis.

EVIDENCE

Published literature was retrieved through searches of PubMed, CINAHL, Sociological Abstracts, and The Cochrane Library in 2011 using appropriate controlled vocabulary (e.g.,cultural competency, health services, indigenous, transcultural nursing) and key words (e.g., indigenous health services, transcultural health care, cultural safety). Targeted searches on subtopics (e.g., ceremonial rites and sexual coming of age) were also performed. The PubMed search was restricted to the years 2005 and later because of the large number of records retrieved on this topic. Searches were updated on a regular basis and incorporated in the guideline to May 2012. Grey (unpublished) literature was identified through searching the websites of selected related agencies (e.g., Campbell Collaboration, Social Care Online, Institute for Healthcare Improvement).

VALUES

The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task force on Preventive Health Care (Table).

Sociodemographic changes over 25 years of pediatric epilepsy surgery at UCLA

OBJECT

Low income, government insurance, and minority status are associated with delayed treatment for neurosurgery patients. Less is known about the influence of referral location and how socioeconomic factors and referral patterns evolve over time. For pediatric epilepsy surgery patients at the University of California, Los Angeles (UCLA), this study determined how referral location and sociodemographic features have evolved over 25 years.

METHODS

Children undergoing epilepsy neurosurgery at UCLA (453 patients) were classified by location of residence and compared with clinical epilepsy and sociodemographic factors.

RESULTS

From 1986 to 2010, referrals from Southern California increased (+33%) and referrals from outside of California decreased (-19%). Over the same period, the number of patients with preferred provider organization (PPO) and health maintenance organization (HMO) insurance increased (+148% and +69%, respectively) and indemnity insurance decreased (-96%). Likewise, the number of Hispanics (+117%) and Asians (100%) increased and Caucasians/whites decreased (-24%). The number of insurance companies decreased from 52 carriers per 100 surgical patients in 1986-1990 to 19 per 100 in 2006-2010. Patients living in the Eastern US had a younger age at surgery (-46%), shorter intervals from seizure onset to referral for evaluation (-28%) and from presurgical evaluation to surgery (-61%) compared with patients from Southern California. The interval from seizure onset to evaluation was shorter (-33%) for patients from Los Angeles County compared with those living in non-California Western US states.

CONCLUSIONS

Referral locations evolved over 25 years at UCLA, with more cases coming from local regions; the percentage of minority patients also increased. The interval from seizures onset to surgery was shortest for patients living farthest from UCLA but still within the US. Geographic location and race/ethnicity was not associated with differences in becoming seizure free after epilepsy surgery in children.

Closing the health equity gap: evidence-based strategies for primary health care organizations

INTRODUCTION

International evidence shows that enhancement of primary health care (PHC) services for disadvantaged populations is essential to reducing health and health care inequities. However, little is known about how to enhance equity at the organizational level within the PHC sector. Drawing on research conducted at two PHC Centres in Canada whose explicit mandates are to provide services to marginalized populations, the purpose of this paper is to discuss (a) the key dimensions of equity-oriented services to guide PHC organizations, and (b) strategies for operationalizing equity-oriented PHC services, particularly for marginalized populations.

METHODS

The PHC Centres are located in two cities within urban neighborhoods recognized as among the poorest in Canada. Using a mixed methods ethnographic design, data were collected through intensive immersion in the Centres, and included: (a) in-depth interviews with a total of 114 participants (73 patients; 41 staff), (b) over 900 hours of participant observation, and (c) an analysis of key organizational documents, which shed light on the policy and funding environments.

RESULTS

Through our analysis, we identified four key dimensions of equity-oriented PHC services: inequity-responsive care; trauma- and violence-informed care; contextually-tailored care; and culturally-competent care. The operationalization of these key dimensions are identified as 10 strategies that intersect to optimize the effectiveness of PHC services, particularly through improvements in the quality of care, an improved 'fit' between people's needs and services, enhanced trust and engagement by patients, and a shift from crisis-oriented care to continuity of care. Using illustrative examples from the data, these strategies are discussed to illuminate their relevance at three inter-related levels: organizational, clinical programming, and patient-provider interactions.

CONCLUSIONS

These evidence- and theoretically-informed key dimensions and strategies provide direction for PHC organizations aiming to redress the increasing levels of health and health care inequities across population groups. The findings provide a framework for conceptualizing and operationalizing the essential elements of equity-oriented PHC services when working with marginalized populations, and will have broad application to a wide range of settings, contexts and jurisdictions. Future research is needed to link these strategies to quantifiable process and outcome measures, and to test their impact in diverse PHC settings.

Informal politics and inequity of access to health care in Lebanon

INTRODUCTION

Despite the importance of political institutions in shaping the social environment, the causal impact of politics on health care access and inequalities has been understudied. Even when considered, research tends to focus on the effects of formal macro-political institutions such as the welfare state. We investigate how micro-politics and informal institutions affect access to care.

METHODS

This study uses a mixed-methods approach, combining findings from a household survey (n = 1789) and qualitative interviews (n = 310) in Lebanon. Multivariate logistic regression was employed in the analysis of the survey to examine the effect of political activism on access to health care while controlling for age, sex, socioeconomic status, religious commitment and piety.

RESULTS

We note a significantly positive association between political activism and the probability of receiving health aid (p < .001), with an OR of 4.0 when comparing individuals with the highest political activity to those least active in our sample. Interviews with key informants also reveal that, although a form of "universal coverage" exists in Lebanon whereby any citizen is eligible for coverage of hospitalization fees and treatments, in practice, access to health services is used by political parties and politicians as a deliberate strategy to gain and reward political support from individuals and their families.

CONCLUSIONS

Individuals with higher political activism have better access to health services than others. Informal, micro-level political institutions can have an important impact on health care access and utilization, with potentially detrimental effects on the least politically connected. A truly universal health care system that provides access based on medical need rather than political affiliation is needed to help to alleviate growing health disparities in the Lebanese population.

Social conditions and urban health inequities: realities, challenges and opportunities to transform the urban landscape through research and action

The process of urbanization entails social improvements with the consequential better quality-of-life for urban residents. However, in many low-income and some middle-income countries, urbanization conveys inequality and exclusion, creating cities and dwellings characterized by poverty, overcrowded conditions, poor housing, severe pollution, and absence of basic services such as water and sanitation. Slums in large cities often have an absence of schools, transportation, health centers, recreational facilities, and other such amenities. Additionally, the persistence of certain conditions, such as poverty, ethnic heterogeneity, and high population turnover, contributes to a lowered ability of individuals and communities to control crime, vandalism, and violence. The social vulnerability in health is not a "natural" or predefined condition but occurs because of the unequal social context that surrounds the daily life of the disadvantaged, and often, socially excluded groups. Social exclusion of individuals and groups is a major threat to development, whether to the community social cohesion and economic prosperity or to the individual self-realization through lack of recognition and acceptance, powerlessness, economic vulnerability, ill health, diminished life experiences, and limited life prospects. In contrast, social inclusion is seen to be vital to the material, psychosocial, and political aspects of empowerment that underpin social well-being and equitable health. Successful experiences of cooperation and networking between slum-based organizations, grassroots groups, local and international NGOs, and city government are important mechanisms that can be replicated in urban settings of different low- and middle-income countries. With increasing urbanization, it is imperative to design health programs for the urban poor that take full advantage of the social resources and resourcefulness of their own communities.

Toward a research and action agenda on urban planning/design and health equity in cities in low and middle-income countries

The importance of reestablishing the link between urban planning and public health has been recognized in recent decades; this paper focuses on the relationship between urban planning/design and health equity, especially in cities in low and middle-income countries (LMICs). The physical urban environment can be shaped through various planning and design processes including urban planning, urban design, landscape architecture, infrastructure design, architecture, and transport planning. The resultant urban environment has important impacts on the health of the people who live and work there. Urban planning and design processes can also affect health equity through shaping the extent to which the physical urban environments of different parts of cities facilitate the availability of adequate housing and basic infrastructure, equitable access to the other benefits of urban life, a safe living environment, a healthy natural environment, food security and healthy nutrition, and an urban environment conducive to outdoor physical activity. A new research and action agenda for the urban environment and health equity in LMICs should consist of four main components. We need to better understand intra-urban health inequities in LMICs; we need to better understand how changes in the built environment in LMICs affect health equity; we need to explore ways of successfully planning, designing, and implementing improved health/health equity; and we need to develop evidence-based recommendations for healthy urban planning/design in LMICs.

Addressing the social and environmental determinants of urban health equity: evidence for action and a research agenda

Urban living is the new reality for the majority of the world's population. Urban change is taking place in a context of other global challenges--economic globalization, climate change, financial crises, energy and food insecurity, old and emerging armed conflicts, as well as the changing patterns of communicable and noncommunicable diseases. These health and social problems, in countries with different levels of infrastructure and health system preparedness, pose significant development challenges in the 21st century. In all countries, rich and poor, the move to urban living has been both good and bad for population health, and has contributed to the unequal distribution of health both within countries (the urban-rural divide) and within cities (the rich-poor divide). In this series of papers, we demonstrate that urban planning and design and urban social conditions can be good or bad for human health and health equity depending on how they are set up. We argue that climate change mitigation and adaptation need to go hand-in-hand with efforts to achieve health equity through action in the social determinants. And we highlight how different forms of governance can shape agendas, policies, and programs in ways that are inclusive and health-promoting or perpetuate social exclusion, inequitable distribution of resources, and the inequities in health associated with that. While today we can describe many of the features of a healthy and sustainable city, and the governance and planning processes needed to achieve these ends, there is still much to learn, especially with respect to tailoring these concepts and applying them in the cities of lower- and middle-income countries. By outlining an integrated research agenda, we aim to assist researchers, policy makers, service providers, and funding bodies/donors to better support, coordinate, and undertake research that is organized around a conceptual framework that positions health, equity, and sustainability as central policy goals for urban management.

Rights, knowledge, and governance for improved health equity in urban settings

All three of the interacting aspects of daily urban life (physical environment, social conditions, and the added pressure of climate change) that affect health inequities are nested within the concept of urban governance, which has the task of understanding and managing the interactions among these different factors so that all three can be improved together and coherently. Governance is defined as: "the process of collective decision making and processes by which decisions are implemented or not implemented": it is concerned with the distribution, exercise, and consequences of power. Although there appears to be general agreement that the quality of governance is important for development, much less agreement appears to exist on what the concept really implies and how it should be used. Our review of the literature confirmed significant variation in meaning as well as in the practice of urban governance arrangements. The review found that the linkage between governance practices and health equity is under-researched and/or has been neglected. Reconnecting the fields of urban planning, social sciences, and public health are essential "not only for improving local governance, but also for understanding and addressing global political change" for enhanced urban health equity. Social mobilization, empowering governance, and improved knowledge for sustainable and equitable development in urban settings is urgently needed. A set of strategic research questions are suggested.

Urban health inequities and the added pressure of climate change: an action-oriented research agenda

Climate change will likely exacerbate already existing urban social inequities and health risks, thereby exacerbating existing urban health inequities. Cities in low- and middle-income countries are particularly vulnerable. Urbanization is both a cause of and potential solution to global climate change. Most population growth in the foreseeable future will occur in urban areas primarily in developing countries. How this growth is managed has enormous implications for climate change given the increasing concentration and magnitude of economic production in urban localities, as well as the higher consumption practices of urbanites, especially the middle classes, compared to rural populations. There is still much to learn about the extent to which climate change affects urban health equity and what can be done effectively in different socio-political and socio-economic contexts to improve the health of urban dwelling humans and the environment. But it is clear that equity-oriented climate change adaptation means attention to the social conditions in which urban populations live-this is not just a climate change policy issue, it requires inter-sectoral action. Policies and programs in urban planning and design, workplace health and safety, and urban agriculture can help mitigate further climate change and adapt to existing climate change. If done well, these will also be good for urban health equity.

Integrated approaches to address the social determinants of health for reducing health inequity

The social and physical environments have long since been recognized as important determinants of health. People in urban settings are exposed to a variety of health hazards that are interconnected with their health effects. The Millennium Development Goals (MDGs) have underlined the multidimensional nature of poverty and the connections between health and social conditions and present an opportunity to move beyond narrow sectoral interventions and to develop comprehensive social responses and participatory processes that address the root causes of health inequity. Considering the complexity and magnitude of health, poverty, and environmental issues in cities, it is clear that improvements in health and health equity demand not only changes in the physical and social environment of cities, but also an integrated approach that takes into account the wider socioeconomic and contextual factors affecting health. Integrated or multilevel approaches should address not only the immediate, but also the underlying and particularly the fundamental causes at societal level of related health issues. The political and legal organization of the policy-making process has been identified as a major determinant of urban and global health, as a result of the role it plays in creating possibilities for participation, empowerment, and its influence on the content of public policies and the distribution of scarce resources. This paper argues that it is essential to adopt a long-term multisectoral approach to address the social determinants of health in urban settings. For comprehensive approaches to address the social determinants of health effectively and at multiple levels, they need explicitly to tackle issues of participation, governance, and the politics of power, decision making, and empowerment.
