As part of a women’s health center project, we reviewed 16 years of research to examine health disparities between women with and without disabilities. We reviewed MEDLINE-indexed articles between 1990 and 2005 with data on women with and without physical, sensory, intellectual, developmental, or psychiatric disabilities. Our review found few articles examining health disparities in chronic disease, cancer, mental health and substance abuse, preventive screening, health-promoting behaviors, and health services utilization. Results reflect apparent health disparities between women with and without disabilities. Challenges for the field exist in standardizing disability definitions and determining a future course for health disparity research and policy. PMID:20446182

A multi-level system quality improvement intervention to reduce racial disparities in hypertension care and control: study protocol

PubMed Central

2013-01-01

Background Racial disparities in blood pressure control have been well documented in the United States. Research suggests that many factors contribute to this disparity, including barriers to care at patient, clinician, healthcare system, and community levels. To date, few interventions aimed at reducing hypertension disparities have addressed factors at all of these levels. This paper describes the design of Project ReD CHiP (Reducing Disparities and Controlling Hypertension in Primary Care), a multi-level system quality improvement project. By intervening on multiple levels, this project aims to reduce disparities in blood pressure control and improve guideline concordant hypertension care. Methods Using a pragmatic trial design, we are implementing three complementary multi-level interventions designed to improve blood pressure measurement, provide patient care management services and offer expanded provider education resources in six primary care clinics in Baltimore, Maryland. We are staggering the introduction of the interventions and will use Statistical Process Control (SPC) charting to determine if there are changes in outcomes at each clinic after implementation of each intervention. The main hypothesis is that each intervention will have an additive effect on improvements in guideline concordant care and reductions in hypertension disparities, but the combination of all three interventions will result in the greatest impact, followed by blood pressure measurement with care management support, blood pressure measurement with provider education, and blood pressure measurement only. This study also examines how organizational functioning and cultural competence affect the success of the interventions. Discussion As a quality improvement project, Project ReD CHiP employs a novel study design that specifically targets multi-level factors known to contribute to hypertension disparities. To facilitate its implementation and improve its sustainability, we have

The national research leadership has recently become aware of the tremendous potential of translational research as an approach to address health disparities. The Research Centers in Minority Institutions (RCMI) Translational Research Network (RTRN) is a research network that supports multi-institutional, multidisciplinary collaboration with a focus on key diseases and conditions for which disproportionately adverse racial and ethnic health disparities exist. The RTRN is designed to facilitate the movement of scientific advances across the translational research spectrum by providing researchers at different institutions with the infrastructure and tools necessary to collaborate on interdisciplinary and transdisciplinary research projects relating to specific health outcomes for which major racial/ethnic disparities exist. In the past, the difficulty of overcoming the restrictions imposed by time and space have made it difficult to carry out this type of large-scale, multilevel collaboration efficiently. To address this formidable challenge, the RTRN will deploy a translational research cluster system that uses “cyber workspaces” to bring researchers with similar interests together by using online collaboratory technology. These virtual meeting environments will provide a number of tools, including videoconferences (seminars, works in progress, meetings); project management tools (WebCT, Microsoft Share Point); and posting areas for projects, concepts, and other research and educational activities. This technology will help enhance access to resources across institutions with a common mission, minimize many of the logistical hurdles that impede intellectual exchange, streamline the planning and implementation of innovative interdisciplinary research, and assess the use of protocols and practices to assist researchers in interacting across and within cyber workspaces.

Payment systems generally do not directly encourage or support the reduction of health disparities. In 2013 the Finding Answers: Solving Disparities through Payment and Delivery System Reform program of the Robert Wood Johnson Foundation sought to understand how alternative payment models might intentionally incorporate a disparities-reduction component to promote health equity. A qualitative analysis of forty proposals to the program revealed that applicants generally did not link payment reform tightly to disparities reduction. Most proposed general pay-for-performance, global payment, or shared savings plans, combined with multicomponent system interventions. None of the applicants proposed making any financial payments contingent on having successfully reduced disparities. Most applicants did not address how they would optimize providers' intrinsic and extrinsic motivation to reduce disparities. A better understanding of how payment and care delivery models might be designed and implemented to reduce health disparities is essential. Project HOPE—The People-to-People Health Foundation, Inc.

Leaders of health care organizations need to be prepared to improve quality and achieve equity in today's health care environment characterized by a focus on achieving value and addressing disparities in a diverse population. To help address this need, the Disparities Solutions Center at Massachusetts General Hospital launched the Disparities Leadership Program in 2007. The leadership program is an ongoing, year-long, executive education initiative that trains leaders from hospitals, health plans, and health centers to improve quality and eliminate racial and ethnic disparities in health care. Feedback from participating organizations demonstrates that health care leaders seem to possess knowledge about what disparities are and about what should be done to eliminate them. Data collection, performance measurement, and multifaceted interventions remain the tools of the trade. However, the barriers to success are lack of leadership buy-in, organizational prioritization, energy, and execution, which can be addressed through organizational change management strategies.

Working across boundaries of power, identity, and political geography is fraught with difficulties and contradictions. In Tali Tal and Iris Alkaher's, " Collaborative environmental projects in a multicultural society: Working from within separate or mutual landscapes?" the authors describe their efforts to do this in the highly charged atmosphere of Israel. This forum article offers a response to their efforts. Writing from a framework of critical pedagogy, I use the concepts of space and time to anchor my analysis, as I examine the issue of power in this Jew/Arab collaborative environmental project. This response problematizes "sharing" in a landscape fraught with disparities. It also looks to further Tal and Alkaher's work by geographically and politically grounding it in the broader current conflict and by juxtaposing sustainability with equity.

Context Reporting on health disparities is fundamental for meeting the goal of reducing health disparities. One often overlooked challenge is determining the best way to report those disparities associated with multiple attributes such as income, education, sex, and race/ethnicity. This article proposes an analytical approach to summarizing social disparities in health, and we demonstrate its empirical application by comparing the degrees and patterns of health disparities in all fifty states and the District of Columbia (DC). Methods We used the 2009 American Community Survey, and our measure of health was functional limitation. For each state and DC, we calculated the overall disparity and attribute-specific disparities for income, education, sex, and race/ethnicity in functional limitation. Along with the state rankings of these health disparities, we developed health disparity profiles according to the attribute making the largest contribution to overall disparity in each state. Findings Our results show a general lack of consistency in the rankings of overall and attribute-specific disparities in functional limitation across the states. Wyoming has the smallest overall disparity and West Virginia the largest. In each of the four attribute-specific health disparity rankings, however, most of the best- and worst-performing states in regard to overall health disparity are not consistently good or bad. Our analysis suggests the following three disparity profiles across states: (1) the largest contribution from race/ethnicity (thirty-four states), (2) roughly equal contributions of race/ethnicity and socioeconomic factor(s) (ten states), and (3) the largest contribution from socioeconomic factor(s) (seven states). Conclusions Our proposed approach offers policy-relevant health disparity information in a comparable and interpretable manner, and currently publicly available data support its application. We hope this approach will spark discussion regarding how best

How is gender implicated in our exploration of health disparities in Canada? Set against the backdrop of federal government policy, this review paper examines the ways in which gender intersects with other health determinants to produce disparate health outcomes. An overview of salient issues including the impact of gender roles, environmental exposures, gender violence, workplace hazards, economic disparities, the costs of poverty, social marginalization and racism, aging, health conditions, interactions with health services, and health behaviours are considered. This review suggests health is detrimentally affected by gender roles and statuses as they intersect with economic disparities, cultural, sexual, physical and historical marginalization as well as the strains of domestic and paid labour. These conditions result in an unfair health burden borne in particular by women whose access to health determinants is--in various degrees--limited. While progress has certainly been made on some fronts, the persistence of health disparities among diverse populations of women and men suggests a postponement of the vision of a just society with health for all that was articulated in the Federal Plan on Gender Equality. Commitment, creativity and collaboration from stakeholders ranging from various levels of government, communities, academics, non-governmental agencies and health professionals will be required to reduce and eliminate health disparities between and among all members of our society.

To reduce racial and ethnic disparities in diabetes care and outcomes, it is critical to integrate health care and community approaches. However, little work describes how to expand and sustain such partnerships and initiatives. We outline our experience creating and growing an initiative to improve diabetes care and outcomes in the predominantly African American South Side of Chicago. Our project involves patient education and activation, a quality improvement collaborative with six clinics, provider education, and community partnerships. We aligned our project with the needs and goals of community residents and organizations, the mission and strategic plan of our academic medical center, various strengths and resources in Chicago, and the changing health care marketplace. We use the Robert Wood Johnson Foundation Finding Answers: Disparities Research for Change conceptual model and the Consolidated Framework for Implementation Research to elucidate how we expanded and sustained our project within a shifting environment. We recommend taking action to integrate health care with community projects, being inclusive, building partnerships, working with the media, and understanding vital historical, political, and economic contexts. © 2014 Society for Public Health Education.

Background Accurate forecasting of cardiovascular disease (CVD) mortality is crucial to guide policy and programming efforts. Prior forecasts have often not incorporated past trends in rates of reduction in CVD mortality. This creates uncertainties about future trends in CVD mortality and disparities. Methods and Results To forecast US CVD mortality and disparities to 2030, we developed a hierarchical Bayesian model to determine and incorporate prior age, period and cohort (APC) effects from 1979–2012, stratified by age, gender and race; which we combined with expected demographic shifts to 2030. Data sources included the National Vital Statistics System, SEER single year population estimates, and US Bureau of Statistics 2012 National Population projections. We projected coronary disease and stroke deaths to 2030, first based on constant APC effects at 2012 values, as most commonly done (conventional); and then using more rigorous projections incorporating expected trends in APC effects (trend-based). We primarily evaluated absolute mortality. The conventional model projected total coronary and stroke deaths by 2030 to increase by approximately 18% (67,000 additional coronary deaths/year) and 50% (64,000 additional stroke deaths/year). Conversely, the trend-based model projected that coronary mortality would fall by 2030 by approximately 27% (79,000 fewer deaths/year); and stroke mortality would remain unchanged (200 fewer deaths/year). Health disparities will be improved in stroke deaths, but not coronary deaths. Conclusions After accounting for prior mortality trends and expected demographic shifts, total US coronary deaths are expected to decline, while stroke mortality will remain relatively constant. Health disparities in stroke, but not coronary, deaths will be improved but not eliminated. These APC approaches offer more plausible predictions than conventional estimates. PMID:26846769

Population disparities in asthma.

2005-01-01

The prevalence of asthma in the United States is higher than in many other countries in the world. Asthma, the most common chronic disease of childhood in the United States, disproportionately burdens many socioeconomically disadvantaged urban communities. In this review we discuss hypotheses for between-country disparities in asthma prevalence, including differences in "hygiene" (e.g., family size, use of day care, early-life respiratory infection exposures, endotoxin and other farm-related exposures, microbial colonization of the infant bowel, exposure to parasites, and exposure to large domestic animal sources of allergen), diet, traffic pollution, and cigarette smoking. We present data on socioeconomic and ethnic disparities in asthma prevalence and morbidity in the United States and discuss environmental factors contributing to asthma disparities (e.g., housing conditions, indoor environmental exposures including allergens, traffic air pollution, disparities in treatment and access to care, and cigarette smoking). We discuss environmental influences on somatic growth (low birth weight, prematurity, and obesity) and their relevance to asthma disparities. The relevance of the hygiene hypothesis to the U.S. urban situation is reviewed. Finally, we discuss community-level factors contributing to asthma disparities.

There are meaningful cancer-related disparities in the Appalachian region of the U.S. To address these disparities, the Appalachia Community Cancer Network (ACCN), a collaboration of investigators and community partners in five states (Kentucky, Ohio, Pennsylvania, Virginia, and West Virginia), is involved in increasing cancer education and awareness, conducting community-based participatory research (CBPR), and creating mentorship and training opportunities. The primary objective of this paper is to describe cancer-related disparities in the Appalachian region of the U.S. as an example of the disparities experienced by underserved, predominantly white, rural populations, and to describe ACCN activities designed to intervene regarding these disparities. An ACCN overview/history and the diverse activities of ACCN-participating states are presented in an effort to suggest potential useful strategies for working to reduce health-related disparities in underserved white populations. Strengths that have emerged from the ACCN approach (e.g., innovative collaborations, long-standing established networks) and remaining challenges (e.g., difficulties with continually changing communities, scarce resources) are described. Important recommendations that have emerged from the ACCN are also presented, including the value of allowing communities to lead CBPR efforts. Characteristics of the community-based work of the ACCN provide a framework for reducing health-related disparities in Appalachia and in other underserved white and rural populations. PMID:21873582

The purpose of this study was to examine rates of 3 bacterial sexually transmitted diseases (STDs; syphilis, gonorrhea, and chlamydia) in 8 subpopulations (known as the "eight Americas") defined by race and a small number of county-level sociodemographic and geographical characteristics. The eight Americas are (1) Asians and Pacific Islanders in specific counties; (2) Northland low-income rural white; (3) Middle America; (4) Low-income whites in Appalachia and Mississippi Valley; (5) Western Native American; (6) Black middle America; (7) Southern low-income rural black; and (8) High-risk urban black. A list of the counties comprising each of the eight Americas was obtained from the corresponding author of the original eight Americas project, which examined disparities in mortality rates across the eight Americas. Using county-level STD surveillance data, we calculated syphilis, gonorrhea, and chlamydia rates (new cases per 100,000) for each of the eight Americas. Reported STD rates varied substantially across the eight Americas. STD rates were generally lowest in Americas 1 and 2 and highest in Americas 6, 7, and 8. Although disparities in STDs across the eight Americas are generally similar to the well-established disparities in STDs across race/ethnicity, the grouping of counties into the eight Americas does offer additional insight into disparities in STDs in the United States. The high STD rates we found for black Middle America are consistent with the assertion that sexual networks and social factors are important drivers of racial disparities in STDs.

Conjunctions between motion and disparity are encoded with the same spatial resolution as disparity alone.

Neurons in cortical area MT respond well to transparent streaming motion in distinct depth planes, such as caused by observer self-motion, but do not contain subregions excited by opposite directions of motion. We therefore predicted that spatial resolution for transparent motion/disparity conjunctions would be limited by the size of MT receptive fields, just as spatial resolution for disparity is limited by the much smaller receptive fields found in primary visual cortex, V1. We measured this using a novel "joint motion/disparity grating," on which human observers detected motion/disparity conjunctions in transparent random-dot patterns containing dots streaming in opposite directions on two depth planes. Surprisingly, observers showed the same spatial resolution for these as for pure disparity gratings. We estimate the limiting receptive field diameter at 11 arcmin, similar to V1 and much smaller than MT. Higher internal noise for detecting joint motion/disparity produces a slightly lower high-frequency cutoff of 2.5 cycles per degree (cpd) versus 3.3 cpd for disparity. This suggests that information on motion/disparity conjunctions is available in the population activity of V1 and that this information can be decoded for perception even when it is invisible to neurons in MT.

Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Study findings are presented according to their association with the prevalence, clinical presentation, management, and outcomes in acute critical illness. This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data are organized along the course of acute critical illness. The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research.

China is one of the largest and most populated countries in the world. It has undergone rapid economic growth in recent years. However, the development is not equitable, and the distribution of wealth significantly varies among the regions in China. Geographical and socioeconomic inequalities, together with the lack of an equitable national social support system, cause the high variance of health outcomes among the regions. Furthermore, the fast growth of the economy has evoked many environmental challenges and puts much pressure on the population. The severe environmental deterioration, especially of the atmosphere and water bodies, has affected the health of the people living in China. As a result, cancer has become a major public health issue, and an alarming increase in incidence and mortality has been reported. However, cancer incidence and mortality vary in different areas in China. Cancer and cancer treatment disparities have existed for years. This article will discuss the existing health and cancer disparities associated with the risk factors and how these disparities are managed in China.

To effectively attenuate cancer disparities in multiethnic, medically underserved populations, interventions must be developed collaboratively through solid community–academic partnerships and driven by community-based participatory research (CBPR). The Tampa Bay Community Cancer Network (TBCCN) has been created to identify and implement interventions to address local cancer disparities in partnership with community-based nonprofit organizations, faith-based groups, community health centers, local media, and adult literacy and education organizations. TBCCN activities and research efforts are geared toward addressing critical information and access issues related to cancer control and prevention in diverse communities in the Tampa Bay area. Such efforts include cross-cultural health promotion, screening, and awareness activities in addition to applied research projects that are rooted in communities and guided by CBPR methods. This article describes these activities as examples of partnership building to positively affect cancer disparities, promote community health, and set the stage for community-based research partnerships.

The Moral Problem of Health Disparities

PubMed Central

2010-01-01

Health disparities exist along lines of race/ethnicity and socioeconomic class in US society. I argue that we should work to eliminate these health disparities because their existence is a moral wrong that needs to be addressed. Health disparities are morally wrong because they exemplify historical injustices. Contractarian ethics, Kantian ethics, and utilitarian ethics all provide theoretical justification for viewing health disparities as a moral wrong, as do several ethical principles of primary importance in bioethics. The moral consequences of health disparities are also troubling and further support the claim that these disparities are a moral wrong. The Universal Declaration of Human Rights provides additional support that health disparities are a moral wrong, as does an analogy with the generally accepted duty to provide equal access to education. In this article, I also consider and respond to 3 objections to my thesis. PMID:20147677

Stereopsis, vertical disparity and relief transformations.

Gårding, J; Porrill, J; Mayhew, J E; Frisby, J P

1995-03-01

The pattern of retinal binocular disparities acquired by a fixating visual system depends on both the depth structure of the scene and the viewing geometry. This paper treats the problem of interpreting the disparity pattern in terms of scene structure without relying on estimates of fixation position from eye movement control and proprioception mechanisms. We propose a sequential decomposition of this interpretation process into disparity correction, which is used to compute three-dimensional structure up to a relief transformation, and disparity normalization, which is used to resolve the relief ambiguity to obtain metric structure. We point out that the disparity normalization stage can often be omitted, since relief transformations preserve important properties such as depth ordering and coplanarity. Based on this framework we analyse three previously proposed computational models of disparity processing; the Mayhew and Longuet-Higgins model, the deformation model and the polar angle disparity model. We show how these models are related, and argue that none of them can account satisfactorily for available psychophysical data. We therefore propose an alternative model, regional disparity correction. Using this model we derive predictions for a number of experiments based on vertical disparity manipulations, and compare them to available experimental data. The paper is concluded with a summary and a discussion of the possible architectures and mechanisms underling stereopsis in the human visual system.

The United States has set a national goal to eliminate health disparities. This article emphasizes the importance of food systems in generating and exacerbating health disparities in the United States and suggests avenues for reducing them. It presents a conceptual model showing how broad food system conditions interplay with community food environments—and how these relationships are filtered and refracted through prisms of social disparities to generate and exacerbate health disparities. Interactions with demand factors in the social environment are described. The article also highlights the separate food systems pathway to health disparities via environmental and occupational health effects of agriculture. PMID:23173027

The purpose of this paper was to describe the development and implementation of a health disparities summer internship program for minority high school students that was created to increase their knowledge of health disparities, provide hands-on training in community-engaged research, support their efforts to advocate for policy change, and further encourage youth to pursue careers in the health professions. Fifty-one high school students who were enrolled in a well-established, science-enrichment after-school program in Brooklyn, New York, participated in a 4-week summer internship program. Students conducted a literature review, focus groups/interviews, geographic mapping or survey development that focused on reducing health disparities at 1 of 15 partnering CBOs. Overall, student interns gained an increase in knowledge of racial/ethnic health disparities. There was a 36.2% increase in students expressing an interest in pursuing careers in minority health post program. The majority of the participating CBOs were able to utilize the results of the student-led research projects for their programs. In addition, research conclusions and policy recommendations based on the students' projects were given to local elected officials. As demonstrated by our program, community-academic partnerships can provide educational opportunities to strengthen the academic pipeline for students of color interested in health careers and health disparities research.

Stereo transparency and the disparity gradient limit

McKee, Suzanne P.; Verghese, Preeti

2002-01-01

Several studies (Vision Research 15 (1975) 583; Perception 9 (1980) 671) have shown that binocular fusion is limited by the disparity gradient (disparity/distance) separating image points, rather than by their absolute disparity values. Points separated by a gradient >1 appear diplopic. These results are sometimes interpreted as a constraint on human stereo matching, rather than a constraint on fusion. Here we have used psychophysical measurements on stereo transparency to show that human stereo matching is not constrained by a gradient of 1. We created transparent surfaces composed of many pairs of dots, in which each member of a pair was assigned a disparity equal and opposite to the disparity of the other member. For example, each pair could be composed of one dot with a crossed disparity of 6' and the other with uncrossed disparity of 6', vertically separated by a parametrically varied distance. When the vertical separation between the paired dots was small, the disparity gradient for each pair was very steep. Nevertheless, these opponent-disparity dot pairs produced a striking appearance of two transparent surfaces for disparity gradients ranging between 0.5 and 3. The apparent depth separating the two transparent planes was correctly matched to an equivalent disparity defined by two opaque surfaces. A test target presented between the two transparent planes was easily detected, indicating robust segregation of the disparities associated with the paired dots into two transparent surfaces with few mismatches in the target plane. Our simulations using the Tsai-Victor model show that the response profiles produced by scaled disparity-energy mechanisms can account for many of our results on the transparency generated by steep gradients.

Multilevel interventions are those that affect at least two levels of influence-for example, the patient and the health care provider. They can be experimental designs or natural experiments caused by changes in policy, such as the implementation of the Affordable Care Act or local policies. Measuring the effects of multilevel interventions is challenging, because they allow for interaction among levels, and the impact of each intervention must be assessed and translated into practice. We discuss how two projects from the National Institutes of Health's Centers for Population Health and Health Disparities used multilevel interventions to reduce health disparities. The interventions, which focused on the uptake of the human papillomavirus vaccine and community-level dietary change, had mixed results. The design and implementation of multilevel interventions are facilitated by input from the community, and more advanced methods and measures are needed to evaluate the impact of the various levels and components of such interventions.

A partnership formed between Northeastern Illinois University (NEIU) and the Robert H. Lurie Comprehensive Cancer Center of Northwestern University sought to address well-documented cancer health disparities in Chicago by developing a collaborative research, training, and educational infrastructure between a minority-serving institution and a National Cancer Institute designated comprehensive cancer center. With a critical examination of partnership documentation and outputs, we describe the partnership’s community-engaged approaches, challenges, and lessons learned. Northeastern Illinois University and the Lurie Cancer Center engaged in a yearlong partnership-building phase, identified interdisciplinary research teams, formed a governance structure, and identified collective aims. Partnership outcomes included funded inter-institutional research projects, new curriculum, and an annual research trainee program. Significant challenges faced included uncertain fiscal climate, widespread turnover, and dissimilar institutional demands. Lessons learned from this minority serving institution and comprehensive cancer center partnership may be useful for bridging distinct academic communities in the pursuit of ameliorating health disparities.

Despite numerous efforts to change healthcare delivery, the profile of disparities in diabetes care and outcomes has not changed substantially over the past decade. To understand potential contributors to disparities in diabetes care and glycemic control. Cross sectional analysis. Seven outpatient clinics affiliated with an academic medical center. Adult patients with type 2 diabetes who were Mexican American, Vietnamese American or non-Hispanic white (n = 1,484). Glycemic control was measured as hemoglobin A1c (HbA1c) level. Patient, provider and system characteristics included demographic characteristics; access to care; quality of process of care including clinical inertia; quality of interpersonal care; illness burden; mastery (diabetes management confidence, passivity); and adherence to treatment. Unadjusted HbA1c values were significantly higher for Mexican American patients (n = 782) (mean = 8.3 % [SD:2.1]) compared with non-Hispanic whites (n = 389) (mean = 7.1 % [SD:1.4]). There were no significant differences in HbA1c values between Vietnamese American and non-Hispanic white patients. There were no statistically significant group differences in glycemic control after adjustment for multiple measures of access, and quality of process and interpersonal care. Disease management mastery and adherence to treatment were related to glycemic control for all patients, independent of race/ethnicity. Generalizability to other minorities or to patients with poorer access to care may be limited. The complex interplay among patient, physician and system characteristics contributed to disparities in HbA1c between Mexican American and non-Hispanic white patients. In contrast, Vietnamese American patients achieved HbA1c levels comparable to non-Hispanic whites and adjustment for numerous characteristics failed to identify confounders that could have masked disparities in this subgroup. Disease management mastery appeared to be an important contributor

Disparity channels in early vision

2008-01-01

The last decade has seen a dramatic increase in our knowledge of the neural basis of stereopsis. New cortical areas have been found to represent binocular disparities, new representations of disparity information (e.g., relative disparity signals) have been uncovered, the first topographic maps of disparity have been measured, and the first causal links between neural activity and depth perception have been established. Equally exciting is the finding that training and experience affects how signals are channeled through different brain areas, a flexibility that may be crucial for learning, plasticity, and recovery of function. The collective efforts of several laboratories have established stereo vision as one of the most productive model systems for elucidating the neural basis of perception. Much remains to be learned about how the disparity signals that are initially encoded in primary visual cortex are routed to and processed by extrastriate areas to mediate the diverse capacities of 3D vision that enhance our daily experience of the world.

Heterophoria does not provide a reliable clue for ordering prisms in an asthenopic patient. The same reservation applies to associated phoria, as determined by prism correction of fixation disparity. Subjective tests for fixation disparity, even those with a fusionable fixation target, do not correctly indicate the vergence position of the eyes under natural viewing conditions. Attempts to measure fixation disparity on the basis of stereo disparity, using the "Measuring and Correction Methods of H.-J. Haase", have failed.

Oregon's Coordinated Care Organizations Increased Timely Prenatal Care Initiation And Decreased Disparities.

Policies at the state and federal levels affect access to health services, including prenatal care. In 2012 the State of Oregon implemented a major reform of its Medicaid program. The new model, called a coordinated care organization (CCO), is designed to improve the coordination of care for Medicaid beneficiaries. This reform effort provides an ideal opportunity to evaluate the impact of broad financing and delivery reforms on prenatal care use. Using birth certificate data from Oregon and Washington State, we evaluated the effect of CCO implementation on the probability of early prenatal care initiation, prenatal care adequacy, and disparities in prenatal care use by type of insurance. Following CCO implementation, we found significant increases in early prenatal care initiation and a reduction in disparities across insurance types but no difference in overall prenatal care adequacy. Oregon's reforms could serve as a model for other Medicaid and commercial health plans seeking to improve prenatal care quality and reduce disparities.

Empowerment to reduce health disparities.

PubMed

Wallerstein, Nina

2002-01-01

This article articulates the theoretical construct of empowerment and its importance for health-enhancing strategies to reduce health disparities. Powerlessness is explored as a risk factor in the context of social determinants, such as poverty, discrimination, workplace hazards, and income inequities. Empowerment is presented and compared with social capital and community capacity as strategies to strengthen social protective factors. A case study of a youth empowerment and policy project in New Mexico illustrates the usefulness of empowerment strategies in both targeting social determinants, such as public policies which are detrimental to youth, and improving community capacities of youth to be advocates for social change. Challenges for future practice and research are articulated.

Latitude and longitude vertical disparity

Read, Jenny C. A.; Phillipson, Graeme P.; Glennerster, Andrew

2010-01-01

The literature on vertical disparity is complicated by the fact that several different definitions of the term “vertical disparity” are in common use, often without a clear statement about which is intended or a widespread appreciation of the properties of the different definitions. Here, we examine two definitions of retinal vertical disparity: elevation-latitude and elevation-longitude disparity. Near the fixation point, these definitions become equivalent, but in general, they have quite different dependences on object distance and binocular eye posture, which have not previously been spelt out. We present analytical approximations for each type of vertical disparity, valid for more general conditions than previous derivations in the literature: we do not restrict ourselves to objects near the fixation point or near the plane of regard, and we allow for non-zero torsion, cyclovergence and vertical misalignments of the eyes. We use these expressions to derive estimates of the latitude and longitude vertical disparity expected at each point in the visual field, averaged over all natural viewing. Finally, we present analytical expressions showing how binocular eye position – gaze direction, convergence, torsion, cyclovergence, and vertical misalignment – can be derived from the vertical disparity field and its derivatives at the fovea.

Over the past several decades, Puerto Ricans have faced increased health threats from chronic diseases, particularly diabetes and hypertension. The patient-provider relationship is the main platform for individual disease management, whereas the community, as an agent of change for the community's health status, has been limited in its support of individual health. Likewise, traditional research approaches within communities have placed academic researchers at the center of the process, considering their knowledge was of greater value than that of the community. In this paradigm, the academic researcher frequently owns and controls the research process. The primary aim is contributing to the scientific knowledge, but not necessarily to improve the community's health status or empower communities for social change. In contrast, the community-based participatory research (CBPR) model brings community members and leaders together with researchers in a process that supports mutual learning and empowers the community to take a leadership role in its own health and well-being. This article describes the development of the community-campus partnership between the University of Puerto Rico School of Medicine and Piñones, a semi-rural community, and the resulting CBPR project: "Salud para Piñones". This project represents a collaborative effort to understand and address the community's health needs and health disparities based on the community's participation as keystone of the process. This participatory approach represents a valuable ally in the development of long-term community-academy partnerships, thus providing opportunities to establish relevant and effective ways to translate evidence-based interventions into concrete actions that impact the individual and community's wellbeing.

Processing vertical size disparities in distinct depth planes.

PubMed

Duke, Philip A; Howard, Ian P

2012-08-17

A textured surface appears slanted about a vertical axis when the image in one eye is horizontally enlarged relative to the image in the other eye. The surface appears slanted in the opposite direction when the same image is vertically enlarged. Two superimposed textured surfaces with different horizontal size disparities appear as two surfaces that differ in slant. Superimposed textured surfaces with equal and opposite vertical size disparities appear as a single frontal surface. The vertical disparities are averaged. We investigated whether vertical size disparities are averaged across two superimposed textured surfaces in different depth planes or whether they induce distinct slants in the two depth planes. In Experiment 1, two superimposed textured surfaces with different vertical size disparities were presented in two depth planes defined by horizontal disparity. The surfaces induced distinct slants when the horizontal disparity was more than ±5 arcmin. Thus, vertical size disparities are not averaged over surfaces with different horizontal disparities. In Experiment 2 we confirmed that vertical size disparities are processed in surfaces away from the horopter, so the results of Experiment 1 cannot be explained by the processing of vertical size disparities in a fixated surface only. Together, these results show that vertical size disparities are processed separately in distinct depth planes. The results also suggest that vertical size disparities are not used to register slant globally by their effect on the registration of binocular direction of gaze.

Health Disparities and Discrimination: Three Perspectives

PubMed Central

Ndiaye, Khadidiatou; Krieger, Janice R.; Warren, Jennifer R.; Hecht, Michael L.; Okuyemi, Kola

2010-01-01

This article presents three perspectives on health discrimination and disparities, organized around different conceptualizations of the way “space” perpetuates health disparities. The first two perspectives are grounded in conceptualizing space in a physical sense by exploring the manifestation of discrimination as a problem both among and within nations. The third perspective juxtaposes geographical space with cyberspace. The internet, with its ability to blur sense of place, social demarcations, and behavior is often considered a panacea that can eliminate the health disparities. The internet, however, may not be fulfilling its promise as an equal source of health information for all and disparities related to international and rural geography remain problematic. Solutions are proposed for reducing health disparities based on The Principle of Cultural Grounding (Hecht & Krieger, 2006; Hecht & Miller-Day, in press). PMID:20694161

Community-based participatory research (CBPR) holds tremendous promise for addressing public health disparities. As such, there is a need for academic institutions to build lasting partnerships with community organizations. Herein we have described the process of establishing a relationship between a research university and a Black church in rural North Carolina. We then discuss Harvest of Hope, the church-based pilot garden project that emerged from that partnership. The partnership began with a third-party effort to connect research universities with Black churches to address health disparities. Building this academic-community partnership included collaborating to determine research questions and programming priorities. Other aspects of the partnership included applying for funding together and building consensus on study budget and aims. The academic partners were responsible for administrative details and the community partners led programming and were largely responsible for participant recruitment. The community and academic partners collaborated to design and implement Harvest of Hope, a church-based pilot garden project involving 44 youth and adults. Community and academic partners shared responsibility for study design, recruitment, programming, and reporting of results. The successful operation of the Harvest of Hope project gave rise to a larger National Institutes of Health (NIH)-funded study, Faith, Farming and the Future (F3) involving 4 churches and 60 youth. Both projects were CBPR efforts to improve healthy food access and reducing chronic disease. This partnership continues to expand as we develop additional CBPR projects targeting physical activity, healthy eating, and environmental justice, among others. Benefits of the partnership include increased community ownership and cultural appropriateness of interventions. Challenges include managing expectations of diverse parties and adequate communication. Lessons learned and strategies for building

Development of Relative Disparity Sensitivity in Human Visual Cortex.

PubMed

Norcia, Anthony M; Gerhard, Holly E; Meredith, Wesley J

Stereopsis is the primary cue underlying our ability to make fine depth judgments. In adults, depth discriminations are supported largely by relative rather than absolute binocular disparity, and depth is perceived primarily for horizontal rather than vertical disparities. Although human infants begin to exhibit disparity-specific responses between 3 and 5 months of age, it is not known how relative disparity mechanisms develop. Here we show that the specialization for relative disparity is highly immature in 4- to 6-month-old infants but is adult-like in 4- to 7-year-old children. Disparity-tuning functions for horizontal and vertical disparities were measured using the visual evoked potential. Infant relative disparity thresholds, unlike those of adults, were equal for vertical and horizontal disparities. Their horizontal disparity thresholds were a factor of ∼10 higher than adults, but their vertical disparity thresholds differed by a factor of only ∼4. Horizontal relative disparity thresholds for 4- to 7-year-old children were comparable with those of adults at ∼0.5 arcmin. To test whether infant immaturity was due to spatial limitations or insensitivity to interocular correlation, highly suprathreshold horizontal and vertical disparities were presented in alternate regions of the display, and the interocular correlation of the interdigitated regions was varied from 0% to 100%. This manipulation regulated the availability of coarse-scale relative disparity cues. Adult and infant responses both increased with increasing interocular correlation by similar magnitudes, but adult responses increased much more for horizontal disparities, further evidence for qualitatively immature stereopsis based on relative disparity at 4-6 months of age. SIGNIFICANCE STATEMENT Stereopsis, our ability to sense depth from horizontal image disparity, is among the finest spatial discriminations made by the primate visual system. Fine stereoscopic depth discriminations depend

Diabetes Health Disparities

Racial and ethnic minorities bear a disproportionate burden of the diabetes epidemic; they have higher prevalence rates, worse diabetes control, and higher rates of complications. This article reviews the effectiveness of health care interventions at improving health outcomes and/or reducing diabetes health disparities among racial/ethnic minorities with diabetes. Forty-two studies met inclusion criteria. On average, these health care interventions improved the quality of care for racial/ethnic minorities, improved health outcomes (such as diabetes control and reduced diabetes complications), and possibly reduced health disparities in quality of care. There is evidence supporting the use of interventions that target patients (primarily through culturally tailored programs), providers (especially through one-on-one feedback and education), and health systems (particularly with nurse case managers and nurse clinicians). More research is needed in the areas of racial/ethnic minorities other than African Americans and Latinos, health disparity reductions, long-term diabetes-related outcomes, and the sustainability of health care interventions over time.

Although colorectal cancer (CRC) mortality rates are declining, racial-ethnic disparities in CRC mortality nationally are widening. Herein, the authors attempted to identify county-level variations in this pattern, and to characterize counties with improving disparity trends. The authors examined 20-year trends in US county-level black-white disparities in CRC age-adjusted mortality rates during the study period between 1989 and 2010. Using a mixed linear model, counties were grouped into mutually exclusive patterns of black-white racial disparity trends in age-adjusted CRC mortality across 20 three-year rolling average data points. County-level characteristics from census data and from the Area Health Resources File were normalized and entered into a principal component analysis. Multinomial logistic regression models were used to test the relation between these factors (clusters of related contextual variables) and the disparity trend pattern group for each county. Counties were grouped into 4 disparity trend pattern groups: 1) persistent disparity (parallel black and white trend lines); 2) diverging (widening disparity); 3) sustained equality; and 4) converging (moving from disparate outcomes toward equality). The initial principal component analysis clustered the 82 independent variables into a smaller number of components, 6 of which explained 47% of the county-level variation in disparity trend patterns. County-level variation in social determinants, health care workforce, and health systems all were found to contribute to variations in cancer mortality disparity trend patterns from 1990 through 2010. Counties sustaining equality over time or moving from disparities to equality in cancer mortality suggest that disparities are not inevitable, and provide hope that more communities can achieve optimal and equitable cancer outcomes for all.

Removing Obstacles To Eliminating Racial And Ethnic Disparities In Behavioral Health Care.

Despite decades of research, racial and ethnic disparities in behavioral health care persist. The Affordable Care Act expanded access to behavioral health care, but many reform initiatives fail to consider research about racial/ethnic minorities. Mistaken assumptions that underlie the expansion of behavioral health care run the risk of replicating existing service disparities. Based on a review of relevant literature and numerous observational and field studies with minority populations, we identified the following three mistaken assumptions: Improvement in health care access alone will reduce disparities, current service planning addresses minority patients' preferences, and evidence-based interventions are readily available for diverse populations. We propose tailoring the provision of care to remove obstacles that minority patients face in accessing treatment, promoting innovative services that respond to patients' needs and preferences, and allowing flexibility in evidence-based practice and the expansion of the behavioral health workforce. These proposals should help meet the health care needs of a growing racial/ethnic minority population. Project HOPE—The People-to-People Health Foundation, Inc.

The neighborhood context of racial and ethnic disparities in arrest.

Kirk, David S

2008-02-01

This study assesses the role of social context in explaining racial and ethnic disparities in arrest, with afocus on how distinct neighborhood contexts in which different racial and ethnic groups reside explain variations in criminal outcomes. To do so, I utilize a multilevel, longitudinal research design, combining individual-level data with contextual data from the Project on Human Development in Chicago Neighborhoods (PHDCN). Findings reveal that black youths face multiple layers of disadvantage relative to other racial and ethnic groups, and these layers work to create differences in arrest. At the family level, results show that disadvantages in the form of unstable family structures explain much of the disparities in arrest across race and ethnicity. At the neighborhood level, black youths tend to reside in areas with both significantly higher levels of concentrated poverty than other youths as well as lower levels of collective efficacy than white youths. Variations in neighborhood tolerance of deviance across groups explain little of the arrest disparities, yet tolerance of deviance does influence the frequency with which a crime ultimately ends in an arrest. Even after accounting for relevant demographic, family, and neighborhood-level predictors, substantial residual arrest differences remain between black youths and youths of other racial and ethnic groups.

This study seeks to examine the process of building the capacity to address health disparities in several urban African American neighborhoods. An inter-organizational network consisting of a research university, community members, community organizations, media partners, and foundations was formed to develop a community-based intervention designed to provide health promotion and disease prevention strategies for type 2 diabetes and hypertension. In-depth qualitative interviews (n = 18) with foundation executives and project directors, civic organization leadership, community leaders, county epidemiologist, and university partners were conducted. Our study contextualizes a process to build a public health partnership using cultural, community, organizational, and societal factors necessary to address health disparities. Results showed 5 important factors to build organizational capacity: leadership, institutional commitment, trust, credibility, and inter-organizational networks. These factors reflected other important organizational and community capacity indicators such as: community context, organizational policies, practices and structures, and the establishment of new commitments and partnerships important to comprehensively address urban health disparities. Understanding these factors to address African American health disparities will provide lessons learned for health educators, researchers, practitioners, foundations, and communities interested in building and sustaining capacity efforts through the design, implementation, and maintenance of a community-based health promotion intervention.

2014-01-01

Objectives To review the extent of health disparities in gynecologic cancer care and outcomes and to propose recommendations to help counteract the disparities. Methods We searched the electronic databases PubMed and the Cochrane Library. We included studies demonstrating quantifiable differences by race and ethnicity in the incidence, treatment, and survival of gynecologic cancers in the United States (US). Most studies relied on retrospective data. We focused on differences between Black and White women, because of the limited number of studies on non-Black women. Results White women have a higher incidence of ovarian cancer compared to Black women. However, the all-cause ovarian cancer mortality in Black women is 1.3 times higher than that of White women. Endometrial and cervical cancer mortality in Black women is twice that of White women. The etiology of these disparities is multifaceted. However, much of the evidence suggests that equal care leads to equal outcomes for Black women diagnosed with gynecologic cancers. Underlying molecular factors may play an additional role in aggressive tumor biology and endometrial cancer disparities. Conclusion Gynecologic cancer disparities exist between Black and White women. The literature is limited by the lack of large prospective trials and adequate numbers of non-Black racial and ethnic groups. We conclude with recommendations for continued research and a multifaceted approach to eliminate gynecologic cancer disparities. PMID:24406291

The Persistence of American Indian Health Disparities

PubMed Central

Jones, David S.

2006-01-01

Disparities in health status between American Indians and other groups in the United States have persisted throughout the 500 years since Europeans arrived in the Americas. Colonists, traders, missionaries, soldiers, physicians, and government officials have struggled to explain these disparities, invoking a wide range of possible causes. American Indians joined these debates, often suggesting different explanations. Europeans and Americans also struggled to respond to the disparities, sometimes working to relieve them, sometimes taking advantage of the ill health of American Indians. Economic and political interests have always affected both explanations of health disparities and responses to them, influencing which explanations were emphasized and which interventions were pursued. Tensions also appear in ongoing debates about the contributions of genetic and socioeconomic forces to the pervasive health disparities. Understanding how these economic and political forces have operated historically can explain both the persistence of the health disparities and the controversies that surround them. PMID:17077399

Integrating disparate lidar datasets for a regional storm tide inundation analysis of Hurricane Katrina

2009-01-01

Hurricane Katrina was one of the largest natural disasters in U.S. history. Due to the sheer size of the affected areas, an unprecedented regional analysis at very high resolution and accuracy was needed to properly quantify and understand the effects of the hurricane and the storm tide. Many disparate sources of lidar data were acquired and processed for varying environmental reasons by pre- and post-Katrina projects. The datasets were in several formats and projections and were processed to varying phases of completion, and as a result the task of producing a seamless digital elevation dataset required a high level of coordination, research, and revision. To create a seamless digital elevation dataset, many technical issues had to be resolved before producing the desired 1/9-arc-second (3meter) grid needed as the map base for projecting the Katrina peak storm tide throughout the affected coastal region. This report presents the methodology that was developed to construct seamless digital elevation datasets from multipurpose, multi-use, and disparate lidar datasets, and describes an easily accessible Web application for viewing the maximum storm tide caused by Hurricane Katrina in southeastern Louisiana, Mississippi, and Alabama.

Reducing and eliminating health disparities: a targeted approach.

Green, B. Lee; Lewis, Rhonda K.; Bediako, Shawn M.

2005-01-01

Health disparities have dominated recent discourse among public health and medical researchers. Ever since the United States began to compile health statistics, differences in health status have been noted between majority and non-majority populations. Myriad approaches have been undertaken in an attempt to reduce or eliminate racial and ethnic disparities in health. However, the disparities continue to persist. We are at a point in our history where innovative strategies must be explored that will be more effective in addressing racial and ethnic disparities in health. In large part, health disparities exist as a result of inequitable distribution of goods, resources, services and power in America. We have learned that improvements in health cannot come about solely through primary and secondary interventions but rather through an examination of the availability of resources that would allow individuals to improve their health. The goal of this paper is to provide an overview of the contextual factors that affect health disparities, to integrate theory to address disparities and to provide recommendations to encourage systematic changes to eliminate health disparities. It is hoped that this paper will bring about a national discussion relating to addressing the real issues we face in reducing and ultimately eliminating health disparities. PMID:15719868

African Americans are disproportionately burdened with colorectal cancer. Although incidence and mortality rates have declined in the past two decades, the disparity in health outcomes has progressively increased. This comprehensive review examines the existing literature regarding racial disparities in colorectal cancer screening, stage at diagnosis, and treatment to determine if differences exist in the quality of care delivered to African Americans. A comprehensive review of relevant literature was performed. Two databases (EBSCOHOST Academic Search Premier and Scopus) were searched from 2000 to 2007. Articles that assessed racial disparities in colorectal cancer screening, stage of disease at diagnosis, and treatment were selected. The majority of studies identified examined colorectal cancer screening outcomes. Although racial disparities in screening have diminished in recent years, African American men and women continue to have higher colorectal cancer incidence and mortality rates and are diagnosed at more advanced stages. Several studies regarding stage of disease at diagnosis identified socioeconomic status (SES) and health insurance status as major determinants of disparity. However, some studies found significant racial disparities even after controlling for these factors. Racial disparities in treatment were also found at various diagnostic stages. Many factors affecting disparities between African Americans and Whites in colorectal cancer incidence and mortality remain unexplained. Although the importance of tumor biology, genetics, and lifestyle risk factors have been established, prime sociodemographic factors need further examination to understand variances in the care of African Americans diagnosed with colorectal cancer.

Health-related disparities: influence of environmental factors.

PubMed

Olden, Kenneth; White, Sandra L

2005-07-01

Racial disparities in health cannot be explained solely on the basis of poverty, access to health care, behavior, or environmental factors. Their complex etiology is dependent on interactions between all these factors plus genetics. Scientists have been slow to consider genetics as a risk factor because genetic polymorphisms tend to be more variable within a race than between races. Now that studies are demonstrating the existence of racial differences in allelic frequencies for multiple genes affecting a single biologic mechanism, the present argument for a significant genetic role in contributing to health disparities is gaining support. Individuals vary, often significantly, in their response to environmental agents. This variability provides a high "background noise" when scientists examine human populations to identify environmental links to disease. This variability often masks important environmental contributors to disease risk and is a major impediment to efforts to investigate the causes of diseases.Fortunately, investments in the various genome projects have led to the development of tools and databases that can be used to help identify the genetic variations in environmental response genes that can lead to such wide differences in disease susceptibility. NIEHS developed the environ-mental genome project to catalog these genetic variants (polymorphisms)and to identify the ones that play a major role in human susceptibility to environmental agents. This information is being used in epidemiologic studies to pinpoint environmental contributors to disease better. The research summarized in this article is critically important for tying genetics and the environment to health disparities, and for the development of a rational approach to gauge environmental threats. Common variants in genes play pivotal roles in determining if or when illness or death result from exposure to drugs or environmental xenobiotics. Most common variants exist in all human

How criminal system racial disparities may translate into health disparities.

Disadvantaged racial and ethnic minorities in the U.S. are strikingly over-represented in the juvenile justice and adult criminal justice systems. This paper briefly reviews the extent of over-representation attributable primarily to drug offenses and an earlier conceptual framework introduced by Iguchi and colleagues showing how the use of incarceration as a key drug control tool has disproportionately affected the health and well being of racial and ethnic minority communities. We then provide observations from the field that demonstrate how the implementation of a quality assessment approach might be used to mitigate procedural/structural biases that contribute to disparities in minority confinement, and ultimately, to reduce disparities in access to resources and health care.

The paper critically examines the understanding, approach and indicators that have been used to measure the degree of disparity. It is fact that disparity exists everywhere. However, this paper highlights on disparities existing between rural and urban areas. In this context, it talks about 'whyí and 'howí disparities exist between rural and urban areas. The study suggests that 'incomeí is not a sufficient indicator to capture the magnitude of disparities at any level. It is, therefore, necessary to develop some indicators representing human resource development and infrastructure facility to understand the growing rural-urban disparity in India.

Health disparities through a psychological lens.

Adler, Nancy E

2009-11-01

There is growing concern in the United States about avoidable, unjust differences in health associated with sociodemographic characteristics, such as socioeconomic status and race/ethnicity. This concern has sparked research to identify how disparities develop and how they can be reduced. Studies showing that disparities occur at all levels of socioeconomic status, not simply at the very bottom, suggest that psychosocial factors play an important role.

Health disparities are an enormous challenge to American society. Addressing these disparities is a priority for U.S. society and especially for institutions of higher learning, with their threefold mission of education, service, and research. Collaboration across multiple intellectual disciplines will be critical as universities address health disparities. In addition, universities must collaborate with communities, with state partners, and with each other. Development of these collaborations must be sensitive to the history and unique characteristics of each academic institution and population. The authors describe the challenges of all three types of collaboration, but primarily focus on collaboration between research-intensive universities and historically black colleges and universities. The authors describe a four-year collaboration between Shaw University and the University of North Carolina at Chapel Hill (UNC-CH). These universities strategically developed multiple research initiatives to address health disparities, building on modest early success and personal relationships. These activities included participation by Shaw faculty in faculty development activities, multiple collaborative pilot studies, and joint participation in securing grants from the Agency for Health care Research and Quality of the federal Department of Health and Human Services and the National Institutes of Health, including a P-60 Project EXPORT center grant. These multiple activities were sometimes led by UNC-CH, sometimes by Shaw University. Open discussion of problems as they arose, realistic expectations, and mutual recognition of the strengths of each institution and its faculty have been critical in achieving successful collaboration to date.

Over the past several decades, Puerto Ricans have faced increased health threats from chronic diseases, particularly diabetes and hypertension. The patient-provider relationship is the main platform for individual disease management, whereas the community, as an agent of change for the community’s health status, has been limited in its support of individual health. Likewise, traditional research approaches within communities have placed academic researchers at the center of the process, considering their knowledge was of greater value than that of the community. In this paradigm, the academic researcher frequently owns and controls the research process. The primary aim is contributing to the scientific knowledge, but not necessarily to improve the community’s health status or empower communities for social change. In contrast, the community-based participatory research (CBPR) model brings community members and leaders together with researchers in a process that supports mutual learning and empowers the community to take a leadership role in its own health and well-being. This article describes the development of the community-campus partnership between the University of Puerto Rico School of Medicine and Piñones, a semi-rural community, and the resulting CBPR project: “Salud para Piñones”. This project represents a collaborative effort to understand and address the community’s health needs and health disparities based on the community’s participation as keystone of the process. This participatory approach represents a valuable ally in the development of long-term community-academy partnerships, thus providing opportunities to establish relevant and effective ways to translate evidence-based interventions into concrete actions that impact the individual and community’s wellbeing.

Though wide disparities in wealth have been documented across racial/ethnic groups, it is largely unknown whether differences in wealth are associated with health disparities within racial/ethnic groups. Data from the Survey of Consumer Finances (2004, ages 25-64) and the Health and Retirement Survey (2004, ages 50+), containing a wide range of assets and debts variables, were used to calculate net worth (a standard measure of wealth). Among non-Hispanic black, Hispanic and non-Hispanic white populations, we tested whether wealth was associated with self-reported poor/fair health status after accounting for income and education. Except among the younger Hispanic population, net worth was significantly associated with poor/fair health status within each racial/ethnic group in both data sets. Adding net worth attenuated the association between education and poor/fair health (in all racial/ethnic groups) and between income and poor/fair health (except among older Hispanics). The results add to the literature indicating the importance of including measures of wealth in health research for what they may reveal about disparities not only between but also within different racial/ethnic groups.

Eliminating health disparities in the African American population: the interface of culture, gender, and power.

Since the release of former Secretary Margaret Heckler's Secretary's Task Force Report on Black and Minority Health more than two decades ago, excess death from chronic diseases and other conditions between African Americans and Whites have increased. The conclusion of that report emphasized excess death and thus clinical care, paying little attention to the sociocultural environment and its effects on risk of disease. The authors of this article contend that eliminating health disparities between the African American and White populations in the United States requires a focus on improving the social environment of African Americans. They examine the interface of culture, gender, and power and how those are central to analysis of the root causes of health disparities. The REACH 2010 project of the Centers for Disease Control offers examples on how a coalition of community and research organizations can infuse community interventions with informed considerations of culture, gender, and power to eliminate health disparities.

Philanthropy and disparities: progress, challenges, and unfinished business.

PubMed

Mitchell, Faith; Sessions, Kathryn

2011-10-01

Philanthropy has invested millions of dollars to reduce disparities in health care and improve minority health. Grants to strengthen providers' cultural competence, diversify health professions, and collect data have improved understanding of and spurred action on disparities. The persistence of disparities in spite of these advances has shifted philanthropic attention toward strategies to change social, economic, and environmental conditions. We argue that these evolving perspectives, along with earlier groundwork, present new opportunities for funders, especially in combination with progress toward universal health coverage. This article looks at how philanthropy has addressed health disparities over the past decade, with a focus on accomplishments, the work remaining to be done, and how funders can help advance the disparities agenda.

Objectives. We sought to quantify how socioeconomic, health care, demographic, and geographic effects explain racial disparities in low birth weight (LBW) and preterm birth (PTB) rates in Brazil. Methods. We employed a sample of 8949 infants born between 1995 and 2009 in 15 cities and 7 provinces in Brazil. We focused on disparities in LBW (< 2500 g) and PTB (< 37 gestational weeks) prevalence between infants of African ancestry alone or African mixed with other ancestries, and European ancestry alone. We used a decomposition model to quantify the contributions of conceptually relevant factors to these disparities. Results. The model explained 45% to 94% of LBW and 64% to 94% of PTB disparities between the African ancestry groups and European ancestry. Differences in prenatal care use and geographic location were the most important contributors, followed by socioeconomic differences. The model explained the majority of the disparities for mixed African ancestry and part of the disparity for African ancestry alone. Conclusions. Public policies to improve children’s health should target prenatal care and geographic location differences to reduce health disparities between infants of African and European ancestries in Brazil.

The opportunities for healthy choices in homes, neighborhoods, schools, and workplaces can have decisive impacts on health. We review scientific evidence from promising interventions focused on the social determinants of health and discuss how such interventions can improve population health and reduce health disparities. We found sufficient evidence of successful outcomes to support disparity-reducing policy interventions targeted at education and early childhood; urban planning and community development; housing; income enhancements and supplements; and employment. Cost-effectiveness evaluations show that these interventions lead to long-term societal savings, but the interventions require more routine attention to cost considerations. We discuss challenges to implementation, including the need for long-term financing to scale up effective interventions for implementation at the local, state, and national levels.

Luminance, Colour, Viewpoint and Border Enhanced Disparity Energy Model

The visual cortex is able to extract disparity information through the use of binocular cells. This process is reflected by the Disparity Energy Model, which describes the role and functioning of simple and complex binocular neuron populations, and how they are able to extract disparity. This model uses explicit cell parameters to mathematically determine preferred cell disparities, like spatial frequencies, orientations, binocular phases and receptive field positions. However, the brain cannot access such explicit cell parameters; it must rely on cell responses. In this article, we implemented a trained binocular neuronal population, which encodes disparity information implicitly. This allows the population to learn how to decode disparities, in a similar way to how our visual system could have developed this ability during evolution. At the same time, responses of monocular simple and complex cells can also encode line and edge information, which is useful for refining disparities at object borders. The brain should then be able, starting from a low-level disparity draft, to integrate all information, including colour and viewpoint perspective, in order to propagate better estimates to higher cortical areas.

Goals for improving the quality of care for all Veterans and eliminating health disparities are outlined in the Veterans Health Administration Blueprint for Excellence, but the degree to which disparities in utilization, health outcomes, and quality of care affect Veterans is not well understood. To characterize the research on health care disparities in the Veterans Health Administration by means of a map of the evidence. We conducted a systematic search for research studies published from 2006 to February 2016 in MEDLINE and other data sources. We included studies of Veteran populations that examined disparities in 3 outcome categories: utilization, quality of health care, and patient health. We abstracted data on study design, setting, population, clinical area, outcomes, mediators, and presence of disparity for each outcome category. We grouped the data by population characteristics including race, disability status, mental illness, demographics (age, era of service, rural location, and distance from care), sex identity, socioeconomic status, and homelessness, and created maps illustrating the evidence. We reviewed 4249 citations and abstracted data from 351 studies which met inclusion criteria. Studies examining disparities by race/ethnicity comprised by far the vast majority of the literature, followed by studies examining disparities by sex, and mental health condition. Very few studies examined disparities related to lesbian, gay, bisexual, or transgender identity or homelessness. Disparities findings vary widely by population and outcome. Our evidence maps provide a "lay of the land" and identify important gaps in knowledge about health disparities experienced by different Veteran populations.

This paper describes a study that focuses on disparity changes in emotional scenes of stereoscopic (3D) images, in which an examination of the effects on pleasant and arousal was carried out by adding binocular disparity to 2D images that evoke specific emotions, and applying disparity modification based on the disparity analysis of famous 3D movies. From the results of the experiment, for pleasant, a significant difference was found only for the main effect of the emotions. On the other hand, for arousal, there was a trend of increasing the evaluation values in the order 2D condition, 3D condition and 3D condition applied the disparity modification for happiness, surprise, and fear. This suggests the possibility that binocular disparity and the modification affect arousal.

Disparities in obesity among rural and urban residents in a health disparate region.

Hill, Jennie L; You, Wen; Zoellner, Jamie M

2014-10-08

The burden of obesity and obesity-related conditions is not borne equally and disparities in prevalence are well documented for low-income, minority and rural adults in the United States. The current literature on rural versus urban disparities is largely derived from national surveillance data which may not reflect regional nuances. There is little practical research that supports the reality of local service providers such as county health departments that may serve both urban and rural residents in a given area. Conducted through a community-academic partnership, the primary aim of this study is to quantify the current levels of obesity (BMI), fruit and vegetable (FV) intake and physical activity (PA) in a predominately rural health disparate region. Secondary aims are to determine if a gradient exists within the region in which rural residents have poorer outcomes on these indicators compared to urban residents. Conducted as part of a larger ongoing community-based participatory research (CBPR) initiative, data were gathered through a random digit dial telephone survey using previously validated measures (n = 784). Linear, logistic and quantile regression models are used to determine if residency (i.e. rural, urban) predicts outcomes of FV intake, PA and BMI. The majority (72%) of respondents were overweight (BMI = 29 ± 6 kg/m2), with 29% being obese. Only 9% of residents met recommendations for FV intake and 38% met recommendations for PA. Statistically significant gradients between urban and rural and race exist at the upper end of the BMI distribution. In other words, the severity of obesity is worse among black compared to white and for urban residents compared to rural residents. These results will be used by the community-academic partnership to guide the development of culturally relevant and sustainable interventions to increase PA, increase FV intake and reduce obesity within this health disparate region. In particular, local stakeholders may wish to

Objectives. Racial disparities in late-life cognition persist even after accounting for educational attainment. We examined whether early-life educational quality and literacy in later life help explain these disparities. Method. We used longitudinal data from the Washington Heights-Inwood Columbia Aging Project (WHICAP). Educational quality (percent white students; urban/rural school; combined grades in classroom) was operationalized using canonical correlation analysis. Late-life literacy (reading comprehension and ability, writing) was operationalized using confirmatory factor analysis. We examined whether these factors attenuated race-related differences in late-life cognition. Results. The sample consisted of 1,679U.S.-born, non-Hispanic, community-living adults aged 65–102 (71% black, 29% white; 70% women). Accounting for educational quality and literacy reduced disparities by 29% for general cognitive functioning, 26% for memory, and 32% for executive functioning but did not predict differences in rate of cognitive change. Discussion. Early-life educational quality and literacy in late life explain a substantial portion of race-related disparities in late-life cognitive function. PMID:24584038

Harnessing Implementation Science to Increase the Impact of Health Disparity Research

Chinman, Matthew; Woodward, Eva N.; Curran, Geoffrey M.; Hausmann, Leslie R. M.

2017-01-01

Background Health disparities are differences in health or health care between groups based on social, economic, and/or environmental disadvantage. Disparity research often follows three steps: detecting (Phase 1), understanding (Phase 2), and reducing (Phase 3), disparities. While disparities have narrowed over time, many remain. Objectives We argue that implementation science could enhance disparities research by broadening the scope of Phase 2 studies and offering rigorous methods to test disparity-reducing implementation strategies in Phase 3 studies. Methods We briefly review the focus of Phase 2 and Phase 3 disparities research. We then provide a decision tree and case examples to illustrate how implementation science frameworks and research designs could further enhance disparity research. Results Most health disparities research emphasizes patient and provider factors as predominant mechanisms underlying disparities. Applying implementation science frameworks like the Consolidated Framework for Implementation Research could help disparities research widen its scope in Phase 2 studies and, in turn, develop broader disparities-reducing implementation strategies in Phase 3 studies. Many Phase 3 studies of disparity reducing implementation strategies are similar to case studies, whose designs are not able to fully test causality. Implementation science research designs offer rigorous methods that could accelerate the pace at which equity is achieved in real world practice. Conclusions Disparities can be considered a “special case” of implementation challenges—when evidence-based clinical interventions are delivered to, and received by, vulnerable populations at lower rates. Bringing together health disparities research and implementation science could advance equity more than either could achieve on their own. PMID:28806362

BACKGROUND The purpose of this study was to determine whether racial disparities in cancer therapy had diminished since the time they were initially documented in the early 1990s. METHODS The authors identified a cohort of patients in the SEER-Medicare linked database who were ages 66 to 85 years and who had a primary diagnosis of colorectal, breast, lung, or prostate cancer during 1992 through 2002. The authors identified 7 stage-specific processes of cancer therapy by using Medicare claims. Candidate covariates in multivariate logistic regression included year, clinical, and sociodemographic characteristics, and physician access before cancer diagnosis. RESULTS During the full study period, black patients were significantly less likely than white patients to receive therapy for cancers of the lung (surgical resection of early stage, 64.0% vs 78.5% for blacks and whites, respectively), breast (radiation after lumpectomy, 77.8% vs 85.8%), colon (adjuvant therapy for stage III, 52.1% vs 64.1%), and prostate (definitive therapy for early stage, 72.4% vs 77.2%, respectively). For both black and white patients, there was little or no improvement in the proportion of patients receiving therapy for most cancer therapies studied, and there was no decrease in the magnitude of any of these racial disparities between 1992 and 2002. Racial disparities persisted even after restricting the analysis to patients who had physician access before their diagnosis. CONCLUSIONS There has been little improvement in either the overall proportion of Medicare beneficiaries receiving cancer therapies or the magnitude of racial disparity. Efforts in the last decade to mitigate cancer therapy disparities appear to have been unsuccessful. PMID:18181101

Objective The objective of this article is to broadly review the scientific literature and summarize the most up-to-date findings on ovarian cancer health disparities worldwide and in the United States (U.S.). Methods The present literature on disparities in ovarian cancer was reviewed. Original research and relevant review articles were included. Results Ovarian cancer health disparities exist worldwide and in the U.S. Ovarian cancer disproportionately affect African American women at all stages of the disease, from presentation through treatment, and ultimately increased mortality and decreased survival, compared to non-Hispanic White women. Increased mortality is likely to be explained by unequal access to care and non-standard treatment regimens frequently administered to African American women, but may also be attributed to genetic susceptibility, acquired co-morbid conditions and increased frequency of modifiable risk factors, albeit to substantially lesser extent. Unequal access to care is, in turn, largely a consequence of lower socioeconomic status and lack of private health insurance coverage among the African American population. Conclusions Our findings suggest the need for policy changes aimed at facilitating equal access to quality medical care. At the same time, further research is necessary to fully resolve racial disparities in ovarian cancer. PMID:23266352

Racial and Ethnic Approaches to Community Health (REACH 2010) is a U.S.Centers for Disease Control and Prevention demonstration program that responds to the U.S. Department of Health and Human Services' goal to eliminate racial and ethnic disparities in health status by the year 2010. As part of REACH 2010, community projects were funded to develop, implement, and evaluate community action plans to improve health care and outcomes for racial and ethnic populations. This article describes the program and details the progress of the REACH 2010: Charleston and Georgetown Diabetes Coalition in reducing disparities in care. Approaches employed by the Coalition included community development, empowerment, and education related to diabetes; health systems change associated with access, care, and education; and coalition advocacy. Racial disparities were identified for 12,000 African Americans with diabetes in this urban/rural South Carolina community. After 24 months, significant differences that initially ranged from 11% to 28% in African Americans (when compared with whites/others) were not observed on 270 chart audits for A1C, lipid and kidney testing, eye examinations, and blood pressure control. Future efforts will focus on maintaining progress, eliminating other disparities, and identifying the contributions of each intervention in eliminating racial disparities. PMID:15158111

The intersection of disability and healthcare disparities: a conceptual framework.

PubMed

Meade, Michelle A; Mahmoudi, Elham; Lee, Shoou-Yih

2015-01-01

This article provides a conceptual framework for understanding healthcare disparities experienced by individuals with disabilities. While health disparities are the result of factors deeply rooted in culture, life style, socioeconomic status, and accessibility of resources, healthcare disparities are a subset of health disparities that reflect differences in access to and quality of healthcare and can be viewed as the inability of the healthcare system to adequately address the needs of specific population groups. This article uses a narrative method to identify and critique the main conceptual frameworks that have been used in analyzing disparities in healthcare access and quality, and evaluating those frameworks in the context of healthcare for individuals with disabilities. Specific models that are examined include the Aday and Anderson Model, the Grossman Utility Model, the Institute of Medicine (IOM)'s models of Access to Healthcare Services and Healthcare Disparities, and the Cultural Competency model. While existing frameworks advance understandings of disparities in healthcare access and quality, they fall short when applied to individuals with disabilities. Specific deficits include a lack of attention to cultural and contextual factors (Aday and Andersen framework), unrealistic assumptions regarding equal access to resources (Grossman's utility model), lack of recognition or inclusion of concepts of structural accessibility (IOM model of Healthcare Disparities) and exclusive emphasis on supply side of the healthcare equation to improve healthcare disparities (Cultural Competency model). In response to identified gaps in the literature and short-comings of current conceptualizations, an integrated model of disability and healthcare disparities is put forth. We analyzed models of access to care and disparities in healthcare to be able to have an integrated and cohesive conceptual framework that could potentially address issues related to access to

Racial and ethnic disparities in human papillomavirus-associated cancer burden with first-generation and second-generation human papillomavirus vaccines.

In the United States, the burden of human papillomavirus (HPV)-associated cancers varies by racial/ethnic group. HPV vaccination may provide opportunities for primary prevention of these cancers. Herein, the authors projected changes in HPV-associated cancer burden among racial/ethnic groups under various coverage assumptions with the available first-generation and second-generation HPV vaccines to evaluate changes in racial/ethnic disparities. Cancer-specific mathematical models simulated the burden of 6 HPV-associated cancers. Model parameters, informed using national registries and epidemiological studies, reflected sex-specific, age-specific, and racial/ethnic-specific heterogeneities in HPV type distribution, cancer incidence, stage of disease at detection, and mortality. Model outcomes included the cumulative lifetime risks of developing and dying of 6 HPV-associated cancers. The level of racial/ethnic disparities was evaluated under each alternative HPV vaccine scenario using several metrics of social group disparity. HPV vaccination is expected to reduce the risks of developing and dying of HPV-associated cancers in all racial/ethnic groups as well as reduce the absolute degree of disparities. However, alternative metrics suggested that relative disparities would persist and in some scenarios worsen. For example, when assuming high uptake with the second-generation HPV vaccine, the lifetime risk of dying of an HPV-associated cancer for males decreased by approximately 60%, yet the relative disparity increased from 3.0 to 3.9. HPV vaccines are expected to reduce the overall burden of HPV-associated cancers for all racial/ethnic groups and to reduce the absolute disparity gap. However, even with the second-generation vaccine, relative disparities will likely still exist and may widen if the underlying causes of these disparities remain unaddressed.

Socioeconomic Disparities in Health Behaviors

PubMed Central

Pampel, Fred C.; Krueger, Patrick M.; Denney, Justin T.

2011-01-01

The inverse relationships between socioeconomic status (SES) and unhealthy behaviors such as tobacco use, physical inactivity, and poor nutrition have been well demonstrated empirically but encompass diverse underlying causal mechanisms. These mechanisms have special theoretical importance because disparities in health behaviors, unlike disparities in many other components of health, involve something more than the ability to use income to purchase good health. Based on a review of broad literatures in sociology, economics, and public health, we classify explanations of higher smoking, lower exercise, poorer diet, and excess weight among low-SES persons into nine broad groups that specify related but conceptually distinct mechanisms. The lack of clear support for any one explanation suggests that the literature on SES disparities in health and health behaviors can do more to design studies that better test for the importance of the varied mechanisms.

2018-06-01

To identify the most appropriate imputation method for missing data in the HCUP State Inpatient Databases (SID) and assess the impact of different missing data methods on racial disparities research. HCUP SID. A novel simulation study compared four imputation methods (random draw, hot deck, joint multiple imputation [MI], conditional MI) for missing values for multiple variables, including race, gender, admission source, median household income, and total charges. The simulation was built on real data from the SID to retain their hierarchical data structures and missing data patterns. Additional predictive information from the U.S. Census and American Hospital Association (AHA) database was incorporated into the imputation. Conditional MI prediction was equivalent or superior to the best performing alternatives for all missing data structures and substantially outperformed each of the alternatives in various scenarios. Conditional MI substantially improved statistical inferences for racial health disparities research with the SID. © Health Research and Educational Trust.

Disparity modification in stereoscopic images for emotional enhancement

2015-03-01

This paper describes an experiment that focuses on disparity changes in emotional scenes of stereoscopic (3D) images, in which an examination of the effects on pleasant and arousal was carried out by adding binocular disparity to 2D images that evoke specific emotions, and applying disparity modification based on the disparity analysis of prominent 3D movies. From the results of the experiment, it was found that pleasant and arousal was increased by expanding 3D space to a certain level. In addition, pleasant gradually decreased and arousal gradually increased by expansion of 3D space above a certain level.

Health disparity knowledge and support for intervention in Saskatoon.

Lemstra, Mark; Neudorf, Cory; Beaudin, Gary

2007-01-01

A number of reports suggest that we need to determine public understanding about the broad determinants of health and also determine public support for actions to reduce health disparities in Canada. A cross-sectional random survey of 5,000 Saskatoon residents was used to determine knowledge about health determinants and health disparity and then determine public support for various interventions to address health disparity. Saskatoon residents understand most of the determinants of health except they understate the importance of social class and gender. Saskatoon residents do not have a good understanding of the magnitude of health disparity between income groups. A majority believe risk behaviours are mostly individual choices and are not associated with income status. Most residents believe even small differences in health status between income groups is unacceptable and a majority believe that something can be done to address health disparity by income status. Interventions proposed by residents to alleviate health disparity were evidence-based, including work-earning supplements and strengthening early intervention programs. Logistic regression revealed that greatest support for transferring money from health care treatment to health creation services (like affordable housing and education) came from young Aboriginal males with low income. Saskatoon residents have knowledge of health determinants and have a strong desire to support health disparity intervention. More knowledge transfer is required on the magnitude of health disparity based on income status. Broad-based health disparity intervention in Saskatoon appears possible.

Health disparities and health equity: concepts and measurement.

PubMed

Braveman, Paula

2006-01-01

There is little consensus about the meaning of the terms "health disparities," "health inequalities," or "health equity." The definitions can have important practical consequences, determining the measurements that are monitored by governments and international agencies and the activities that will be supported by resources earmarked to address health disparities/inequalities or health equity. This paper aims to clarify the concepts of health disparities/inequalities (used interchangeably here) and health equity, focusing on the implications of different definitions for measurement and hence for accountability. Health disparities/inequalities do not refer to all differences in health. A health disparity/inequality is a particular type of difference in health (or in the most important influences on health that could potentially be shaped by policies); it is a difference in which disadvantaged social groups-such as the poor, racial/ethnic minorities, women, or other groups who have persistently experienced social disadvantage or discrimination-systematically experience worse health or greater health risks than more advantaged social groups. ("Social advantage" refers to one's relative position in a social hierarchy determined by wealth, power, and/or prestige.) Health disparities/inequalities include differences between the most advantaged group in a given category-e.g., the wealthiest, the most powerful racial/ethnic group-and all others, not only between the best- and worst-off groups. Pursuing health equity means pursuing the elimination of such health disparities/inequalities.

Response functions for sine- and square-wave modulations of disparity.

Depth sensations cannot be elicited by modulations of disparity that are more rapid than about 6 Hz, regardless of the modulation amplitude. Vergence tracking also fails at similar modulation rates, suggesting that this portion of the oculomotor system is limited by the behavior of disparity detectors. For sinusoidal modulations of disparity between 1/2 to 2 deg of disparity, most depth-response functions exhibit a low-frequency decrease that is not observed with square-wave modulations of disparity.

Health disparities in chickenpox or shingles in Alberta?

Russell, M L; Schopflocher, D P; Svenson, L W

2008-01-01

Exploring for evidence of socio-economic health disparities in chickenpox and shingles in Alberta, Canada. Chickenpox and shingles cases were identified from administrative data from Alberta's universal health care insurance system for 1994-2002. Incident cases were those with the earliest dated utilization of a health service (chickenpox: ICD9-CM 052/ICD10-CA B01; shingles: ICD9-CM 053/ ICD10-CA B02). Crude and age-specific rates were estimated for each year by an indicator of socio-demographic status based upon the nature of the payer and eligibility for health care premium subsidy (SES-proxy) for the provincial health care insurance system. Among young children there is a gradient of disparity in chickenpox rates prior to the year in which publicly funded vaccination programs were implemented. After this point, disparities decline but less so for First Nations children than for others. There was no evidence of disparity by SES-proxy for shingles. Publicly funded vaccination programs may effectively contribute to reduction in disease disparities for vaccine-preventable diseases. Further study is required to ascertain why disparities continue for First Nations children.

Individual Objective and Subjective Fixation Disparity in Near Vision

PubMed Central

Jaschinski, Wolfgang

2017-01-01

Binocular vision refers to the integration of images in the two eyes for improved visual performance and depth perception. One aspect of binocular vision is the fixation disparity, which is a suboptimal condition in individuals with respect to binocular eye movement control and subsequent neural processing. The objective fixation disparity refers to the vergence angle between the visual axes, which is measured with eye trackers. Subjective fixation disparity is tested with two monocular nonius lines which indicate the physical nonius separation required for perceived alignment. Subjective and objective fixation disparity represent the different physiological mechanisms of motor and sensory fusion, but the precise relation between these two is still unclear. This study measures both types of fixation disparity at viewing distances of 40, 30, and 24 cm while observers fixated a central stationary fusion target. 20 young adult subjects with normal binocular vision were tested repeatedly to investigate individual differences. For heterophoria and subjective fixation disparity, this study replicated that the binocular system does not properly adjust to near targets: outward (exo) deviations typically increase as the viewing distance is shortened. This exo proximity effect—however—was not found for objective fixation disparity, which–on the average–was zero. But individuals can have reliable outward (exo) or inward (eso) vergence errors. Cases with eso objective fixation disparity tend to have less exo states of subjective fixation disparity and heterophoria. In summary, the two types of fixation disparity seem to respond in a different way when the viewing distance is shortened. Motor and sensory fusion–as reflected by objective and subjective fixation disparity–exhibit complex interactions that may differ between individuals (eso versus exo) and vary with viewing distance (far versus near vision).

Identifying health disparities across the tobacco continuum.

Few frameworks have addressed work-force diversity, inequities and inequalities as part of a comprehensive approach to eliminating tobacco-related health disparities. This paper summarizes the literature and describes the known disparities that exist along the tobacco disease continuum for minority racial and ethnic groups, those living in poverty, those with low education and blue-collar and service workers. The paper also discusses how work-force diversity, inequities in research practice and knowledge allocation and inequalities in access to and quality of health care are fundamental to addressing disparities in health. We examined the available scientific literature and existing public health reports to identify disparities across the tobacco disease continuum by minority racial/ethnic group, poverty status, education level and occupation. Results indicate that differences in risk indicators along the tobacco disease continuum do not explain fully tobacco-related cancer consequences among some minority racial/ethnic groups, particularly among the aggregate groups, blacks/African Americans and American Indians/Alaska Natives. The lack of within-race/ethnic group data and its interactions with socio-economic factors across the life-span contribute to the inconsistency we observe in the disease causal paradigm. More comprehensive models are needed to understand the relationships among disparities, social context, diversity, inequalities and inequities. A systematic approach will also help researchers, practitioners, advocates and policy makers determine critical points for interventions, the types of studies and programs needed and integrative approaches needed to eliminate tobacco-related disparities.

Racial Healthcare Disparities: A Social Psychological Analysis

Around the world, members of racial/ethnic minority groups typically experience poorer health than members of racial/ethnic majority groups. The core premise of this article is that thoughts, feelings, and behaviors related to race and ethnicity play a critical role in healthcare disparities. Social psychological theories of the origins and consequences of these thoughts, feelings, and behaviors offer critical insights into the processes responsible for these disparities and suggest interventions to address them. We present a multilevel model that explains how societal, intrapersonal, and interpersonal factors can influence ethnic/racial health disparities. We focus our literature review, including our own research, and conceptual analysis at the intrapersonal (the race-related thoughts and feelings of minority patients and non-minority physicians) and interpersonal levels (intergroup processes that affect medical interactions between minority patients and non-minority physicians). At both levels of analysis, we use theories of social categorization, social identity, contemporary forms of racial bias, stereotype activation, stigma, and other social psychological processes to identify and understand potential causes and processes of health and healthcare disparities. In the final section, we identify theory-based interventions that might reduce ethnic/racial disparities in health and healthcare. PMID:25197206

Disparities at the intersection of marginalized groups

2016-01-01

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. 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 males from the National Longitudinal Survey of Youth, examining disparities for black males with low early life SES vs. white males with high early life SES across several outcomes that predict mental health, including unemployment, wages, and incarceration. We report striking disparities in each outcome, but show that the contribution of race, SES, and their intersection varies. PMID:27531592

While persistent racial/ethnic disparities in influenza vaccination have been reported among the elderly, characteristics contributing to disparities are poorly understood. This study aimed to assess characteristics associated with racial/ethnic disparities in influenza vaccination using a nonlinear Oaxaca-Blinder decomposition method. We performed cross-sectional multivariable logistic regression analyses for which the dependent variable was self-reported receipt of influenza vaccine during the 2010–2011 season among community dwelling non-Hispanic African-American (AA), non-Hispanic White (W), English-speaking Hispanic (EH) and Spanish-speaking Hispanic (SH) elderly, enrolled in the 2011 Medicare Current Beneficiary Survey (MCBS) (un-weighted/weighted N= 6,095/19.2million). Using the nonlinear Oaxaca-Blinder decomposition method, we assessed the relative contribution of seventeen covariates—including socio-demographic characteristics, health status, insurance, access, preference regarding healthcare, and geographic regions —to disparities in influenza vaccination. Unadjusted racial/ethnic disparities in influenza vaccination were 14.1 percentage points (pp) (W-AA disparity, p<.001), 25.7 pp (W-SH disparity, p<.001) and 0.6 pp (W-EH disparity, p>.8). The Oaxaca-Blinder decomposition method estimated that the unadjusted W-AA and W-SH disparities in vaccination could be reduced by only 45% even if AA and SH groups become equivalent to Whites in all covariates in multivariable regression models. The remaining 55% of disparities were attributed to (a) racial/ethnic differences in the estimated coefficients (e.g., odds ratios) in the regression models and (b) characteristics not included in the regression models. Our analysis found that only about 45% of racial/ethnic disparities in influenza vaccination among the elderly could be reduced by equalizing recognized characteristics among racial/ethnic groups. Future studies are needed to identify additional

Stigma and Racial/Ethnic HIV Disparities: Moving Toward Resilience

Prior research suggests that stigma plays a role in racial/ethnic health disparities. However, there is limited understanding about the mechanisms by which stigma contributes to HIV-related disparities in risk, incidence and screening, treatment, and survival and what can be done to reduce the impact of stigma on these disparities. We introduce the Stigma and HIV Disparities Model to describe how societal stigma related to race and ethnicity is associated with racial/ethnic HIV disparities via its manifestations at the structural level (e.g., residential segregation) as well as the individual level among perceivers (e.g., discrimination) and targets (e.g., internalized stigma). We then review evidence of these associations. Because racial/ethnic minorities at risk of and living with HIV often possess multiple stigmas (e.g., HIV-positive, substance use), we adopt an intersectionality framework and conceptualize interdependence among co-occurring stigmas. We further propose a resilience agenda and suggest that intervening on modifiable strength-based moderators of the association between societal stigma and disparities can reduce disparities. Strengthening economic and community empowerment and trust at the structural level, creating common ingroup identities and promoting contact with people living with HIV among perceivers at the individual level, and enhancing social support and adaptive coping among targets at the individual level can improve resilience to societal stigma and ultimately reduce racial/ethnic HIV disparities.

Major efforts have been made to improve the health care system in Hunan province, China. The aims of this study were to assess whether and to what extent these efforts have impacted on gender and regional disparities of Tuberculosis (TB) incidence in recent years, especially for less developed areas. We obtained data from the 2005-2009 China Information System for Disease Control and Prevention (CISDCP)to conduct this study in Hunan province. Counties within the province were divided into four regions according to quartiles based on the 2007 per capita GDP. Index of Disparity (ID) and Relative Index of Inequality (RII) were used to measure the disparities of TB incidence in relation to gender and region. Bootstrap technique was used to increase the precision. The average annual incidence of TB was 111.75 per 100,000 in males and 43.44 per 100 000 in females in Hunan. The gender disparity was stable, with ID from 42.34 in 2005 to 43.92 in 2009. For regional disparity, ID, RII (mean) and RII (ratio) decreased significantly from 2005 to 2009 in males (P < 0.05) but remained stable among the female population. As interventions such as introduction of the New Rural Cooperative Scheme put in place to reduce health disparities in China, regional disparity in relation to incidence of TB decreased significantly, but the gender disparity remains in the Hunan province.

Health care disparities in emergency medicine.

The Institute of Medicine's landmark report, "Unequal Treatment: Confronting Racial and Ethnic Disparities in Health Care," documents the pervasiveness of racial and ethnic disparities in the U.S. health care delivery system, and provides several recommendations to address them. It is clear from research data, such as those demonstrating racial and ethnic disparities in emergency department (ED) pain management, that emergency medicine (EM) is not immune to this problem. The IOM authors describe two strategies that can reduce disparities in EM. First, workforce diversity is likely to result in a community of emergency physicians who are better prepared to understand, learn from, and collaborate with persons from other racial, ethnic, and cultural backgrounds, whether these be patients, fellow clinicians, or the larger medical and scientific community. Given the ethical and practical advantages of a more diverse EM workforce, continued and expanded initiatives to increase diversity within EM should be undertaken. Second, the specialty's educational programs should produce emergency physicians with the skills and knowledge needed to serve an increasingly diverse population. This cultural competence should include an awareness of existing racial and ethnic health disparities, recognition of the risks of stereotyping and biased treatment, and knowledge of the incidence and prevalence of health conditions among diverse populations. Culturally competent emergency care providers also possess the skills to identify and manage racial and ethnic differences in health values, beliefs, and behaviors with the ultimate goal of delivering quality health services to all patients cared for in EDs.

Ethnic disparities in cardiovascular health.

Ofili, E

Disparities in the cardiovascular outcomes of African-American patients is evident from national, regional, and local statistical data, as well as from the daily practice of medicine. This discussion highlights the complexity of ethnic disparities using a case-based approach with two typical cases from a cardiology practice. These cases underscore the complex interplay of the following factors in ethnic disparities. 1. Excess burden of cardiovascular risk factors in African Americans, with particular emphasis on high blood pressure, diabetes, obesity, physical inactivity, and psychosocial stress. 2. Inadequate knowledge of how personal risk factors are directly linked to atherosclerosis and heart disease. 3. Cultural factors in symptom recognition and health-care seeking behavior. 4. Economic factors influencing access to health care including prevention, diagnosis, and treatment. 5. A combination of psychosocial stress, racism, and frustration leading to sub-optimal interactions with the health care system. 6. Genetics of disease and predisposition to vascular disease and atherosclerosis. We must come to terms with these fundamental factors in the causation and, therefore, the resolution of ethnic disparities in cardiovascular health. Successful strategies must include: 1) partnerships for long-term, sustainable, population-wide strategies on risk factor modification; 2) models of culturally competent health care delivery; and 3) research on the gene-environment interactions, which cause the susceptibility of ethnic minorities to cardiovascular disease.

African Americans in the United States are more likely than their white counterparts to experience greater incidence and mortality due to colorectal cancer (CRC). Present for decades, these disparities have prompted researchers to investigate underlying causes and potential explanations. While some biological variations have been observed between races, evidence shows that approximately 50% of these disparities can be attributed to differences and disparities in CRC screening, resulting in reduced polyp removal for CRC prevention and/or early detection of CRC among African Americans. Other major contributors to CRC disparities are differences in treatment and access to care. Significant efforts are needed to increase CRC screening among African Americans through targeted interventions to reduce barriers such as increasing education, promoting physician recommendations, and providing affordable and quality care. Intervention is also needed to educate the medical community about these issues and to change health policy to provide a multilevel approach with the best chance of success in reducing racial disparities in CRC.

Previous mental health care disparities studies predominantly compare mean mental health care use across racial/ethnic groups, leaving policymakers with little information on disparities among those with a higher level of expenditures. To identify racial/ethnic disparities among individuals at varying quantiles of mental health care expenditures. To assess whether disparities in the upper quantiles of expenditure differ by insurance status, income and education. Data were analyzed from a nationally representative sample of white, black and Latino adults 18 years and older (n=83,878). Our dependent variable was total mental health care expenditure. We measured disparities in any mental health care expenditures, disparities in mental health care expenditure at the 95th, 97.5 th, and 99 th expenditure quantiles of the full population using quantile regression, and at the 50 th, 75 th, and 95 th quantiles for positive users. In the full population, we tested interaction coefficients between race/ethnicity and income, insurance, and education levels to determine whether racial/ethnic disparities in the upper quantiles differed by income, insurance and education. Significant Black-white and Latino-white disparities were identified in any mental health care expenditures. In the full population, moving up the quantiles of mental health care expenditures, Black-White and Latino-White disparities were reduced but remained statistically significant. No statistically significant disparities were found in analyses of positive users only. The magnitude of black-white disparities was smaller among those enrolled in public insurance programs compared to the privately insured and uninsured in the 97.5 th and 99 th quantiles. Disparities persist in the upper quantiles among those in higher income categories and after excluding psychiatric inpatient and emergency department (ED) visits. Disparities exist in any mental health care and among those that use the most mental health care

In 2001, the U.S. Department of Health and Human Services published Healthy People 2010, which identified objectives to guide health promotion and to eliminate health disparities. Since 2001, much research has been published documenting racial and ethnic disparities in healthcare. Although progress has been made in eliminating the disparities, ongoing work by public health social workers, researchers, and policy analysts is needed. This paper focuses on racial and ethnic health disparities, why they exist, where they can be found, and some of the key health/medical conditions identified by the U.S. Department of Health and Human Services to receive attention. Finally, there is a discussion of what policy, professional and community education, and research can to do to eliminate racial and ethnic disparities in healthcare.

A Persistent Disparity: Smoking in Rural Sexual and Gender Minorities.

2015-03-01

Sexual and gender minorities (SGM) smoke cigarettes at higher rates than the general population. Historically, research in SGM health issues was conducted in urban populations and recent population-based studies seldom have sufficient SGM participants to distinguish urban from rural. Given that rural populations also tend to have a smoking disparity, and that many SGM live in rural areas, it is vitally important to understand the intersection of rural residence, SGM identity, and smoking. This study analyzes the patterns of smoking in urban and rural SGM in a large sample. We conducted an analysis of 4280 adult participants in the Out, Proud, and Healthy project with complete data on SGM status, smoking status, and zip code. Surveys were conducted at 6 Missouri Pride Festivals and online in 2012. Analysis involved descriptive and bivariate methods, and multivariable logistic regression. We used GIS mapping to demonstrate the dispersion of rural SGM participants. SGM had higher smoking proportion than the non-SGM recruited from these settings. In the multivariable model, SGM identity conferred 1.35 times the odds of being a current smoker when controlled for covariates. Rural residence was not independently significant, demonstrating the persistence of the smoking disparity in rural SGM. Mapping revealed widespread distribution of SGM in rural areas. The SGM smoking disparity persists among rural SGM. These communities would benefit from continued research into interventions targeting both SGM and rural tobacco control measures. Recruitment at Pride Festivals may provide a venue for reaching rural SGM for intervention.

Numerous factors play a part in health disparities. Although health disparities are manifested at the level of the individual, other contexts should be considered when investigating the associations of disparities with clinical outcomes. These contexts include families, neighborhoods, social organizations, and healthcare facilities. This paper reports on health disparities research as a multilevel research domain from the perspective of a large national initiative. The Centers for Population Health and Health Disparities (CPHHD) program was established by the NIH to examine the highly dimensional, complex nature of disparities and their effects on health. Because of its inherently transdisciplinary nature, the CPHHD program provides a unique environment in which to perform multilevel health disparities research. During the course of the program, the CPHHD centers have experienced challenges specific to this type of research. The challenges were categorized along three axes: sources of subjects and data, data characteristics, and multilevel analysis and interpretation. The CPHHDs collectively offer a unique example of how these challenges are met; just as importantly, they reveal a broad range of issues that health disparities researchers should consider as they pursue transdisciplinary investigations in this domain, particularly in the context of a large team science initiative.

Freeman, William

2014-01-01

Health care is an important lever for moderating the effects of social determinants on health. We present a model that describes the relationships among social disadvantage, health-care disparities, and health disparities. Improving access to health care and enhancing patient-provider interaction are critical pathways for reducing disparities. Increasing the diversity of the public health and health-care workforces is an efficient strategy for reducing disparities because it impacts both access to care and patient-provider communication. Federal policy makers should continue interest in workforce diversity to optimize the health of all Americans. PMID:24385667

Perspectives of Orthopedic Surgeons on Racial/Ethnic Disparities in Care.

Racial/ethnic disparities in healthcare, including orthopedics, have been extensively documented. However, the level of knowledge among orthopedic surgeons regarding racial/ethnic disparities is unknown. The purpose of this study is to determine the views of orthopedic surgeons on (1) the extent of racial/ethnic disparities in orthopedic care, (2) patient and system factors that may contribute, and (3) the potential role of orthopedic surgeons in the reduction of disparities. Three hundred five members of the American Orthopaedic Association completed a survey to assess their knowledge of racial/ethnic disparities and their perceptions about the underlying causes. Twelve percent of respondents believe that patients often receive different care based on race/ethnicity in healthcare in general, while 9 % believe that differences exist in orthopedic care in general, 3 % believe that differences exist within their hospitals/clinics, and 1 % reported differences in their own practices. Despite this, 68 % acknowledge that there is evidence of disparities in orthopedic care. Fifty-one percent believe that a lack of insurance significantly contributes to disparities. Thirty-five percent believe that diversification of the orthopedic workforce would be a "very effective" strategy in addressing disparities, while 25 % percent believe that research would be "very effective" and 24 % believe that surgeon education would be "very effective." Awareness regarding racial/ethnic disparities in musculoskeletal care is low among orthopedic surgeons. Additionally, respondents were more likely to acknowledge disparities within the practices of others than their own. Increased diversity, research, and education may help improve knowledge of this problem.

Racial disparities in late-life cognition persist even after accounting for educational attainment. We examined whether early-life educational quality and literacy in later life help explain these disparities. We used longitudinal data from the Washington Heights-Inwood Columbia Aging Project (WHICAP). Educational quality (percent white students; urban/rural school; combined grades in classroom) was operationalized using canonical correlation analysis. Late-life literacy (reading comprehension and ability, writing) was operationalized using confirmatory factor analysis. We examined whether these factors attenuated race-related differences in late-life cognition. The sample consisted of 1,679 U.S.-born, non-Hispanic, community-living adults aged 65-102 (71% black, 29% white; 70% women). Accounting for educational quality and literacy reduced disparities by 29% for general cognitive functioning, 26% for memory, and 32% for executive functioning but did not predict differences in rate of cognitive change. Early-life educational quality and literacy in late life explain a substantial portion of race-related disparities in late-life cognitive function. © The Author 2014.

Neural activity in cortical area V4 underlies fine disparity discrimination.

Primates are capable of discriminating depth with remarkable precision using binocular disparity. Neurons in area V4 are selective for relative disparity, which is the crucial visual cue for discrimination of fine disparity. Here, we investigated the contribution of V4 neurons to fine disparity discrimination. Monkeys discriminated whether the center disk of a dynamic random-dot stereogram was in front of or behind its surrounding annulus. We first behaviorally tested the reference frame of the disparity representation used for performing this task. After learning the task with a set of surround disparities, the monkey generalized its responses to untrained surround disparities, indicating that the perceptual decisions were generated from a disparity representation in a relative frame of reference. We then recorded single-unit responses from V4 while the monkeys performed the task. On average, neuronal thresholds were higher than the behavioral thresholds. The most sensitive neurons reached thresholds as low as the psychophysical thresholds. For subthreshold disparities, the monkeys made frequent errors. The variable decisions were predictable from the fluctuation in the neuronal responses. The predictions were based on a decision model in which each V4 neuron transmits the evidence for the disparity it prefers. We finally altered the disparity representation artificially by means of microstimulation to V4. The decisions were systematically biased when microstimulation boosted the V4 responses. The bias was toward the direction predicted from the decision model. We suggest that disparity signals carried by V4 neurons underlie precise discrimination of fine stereoscopic depth.

Objectives. We examined socioeconomic disparities in tobacco dependence treatment outcomes from a free, proactive telephone counseling quitline. Methods. We delivered cognitive–behavioral treatment and nicotine patches to 6626 smokers and examined socioeconomic differences in demographic, clinical, environmental, and treatment use factors. We used logistic regressions and generalized estimating equations (GEE) to model abstinence and account for socioeconomic differences in the models. Results. The odds of achieving long-term abstinence differed by socioeconomic status (SES). In the GEE model, the odds of abstinence for the highest SES participants were 1.75 times those of the lowest SES participants. Logistic regression models revealed no treatment outcome disparity at the end of treatment, but significant disparities 3 and 6 months after treatment. Conclusions. Although quitlines often increase access to treatment for some lower SES smokers, significant socioeconomic disparities in treatment outcomes raise questions about whether current approaches are contributing to tobacco-related socioeconomic health disparities. Strategies to improve treatment outcomes for lower SES smokers might include novel methods to address multiple factors associated with socioeconomic disparities. PMID:24922165

Disparities in long-term care: building equity into market-based reforms.

PubMed

Konetzka, R Tamara; Werner, Rachel M

2009-10-01

A growing body of evidence documents pervasive racial, ethnic, and class disparities in long-term care in the United States. At the same time, major quality improvement initiatives are being implemented that rely on market-based incentives, many of which may have the unintended consequence of exacerbating disparities. We review existing evidence on disparities in the use and quality of long-term care services, analyze current market-based policy initiatives in terms of their potential to ameliorate or exacerbate these disparities, and suggest policies and policy modifications that may help decrease disparities. We find that racial disparities in the use of formal long-term care have decreased over time. Disparities in quality of care are more consistently documented and appear to be related to racial and socioeconomic segregation of long-term care facilities as opposed to within-provider discrimination. Market-based incentives policies should explicitly incorporate the goal of mitigating the potential unintended consequence of increased disparities.

Racial/Ethnic Disparities in Mental Health Care Utilization among U.S. College Students: Applying the Institution of Medicine Definition of Health Care Disparities.

The authors apply the Institute of Medicine's definition of health care disparities to college students. The analysis pools data from the first two waves of the Healthy Minds Study, a multicampus survey of students' mental health (N = 13,028). A probit model was used for any past-year service utilization, and group differences in health status were adjusted by transforming the entire distribution for each minority population to approximate the white distribution. Disparities existed between whites and all minority groups. Compared to other approaches, the predicted service disparities were greater because this method included the effects of mediating SES variables. Health care disparities persist in the college setting despite improved access and nearly universal insurance coverage. Our findings emphasize the importance of investigating potential sources of disparities beyond geography and coverage.

Adaptive Neuromorphic Circuit for Stereoscopic Disparity Using Ocular Dominance Map

Sharma, Sheena; Gupta, Priti; Markan, C. M.

2016-01-01

Stereopsis or depth perception is a critical aspect of information processing in the brain and is computed from the positional shift or disparity between the images seen by the two eyes. Various algorithms and their hardware implementation that compute disparity in real time have been proposed; however, most of them compute disparity through complex mathematical calculations that are difficult to realize in hardware and are biologically unrealistic. The brain presumably uses simpler methods to extract depth information from the environment and hence newer methodologies that could perform stereopsis with brain like elegance need to be explored. This paper proposes an innovative aVLSI design that leverages the columnar organization of ocular dominance in the brain and uses time-staggered Winner Take All (ts-WTA) to adaptively create disparity tuned cells. Physiological findings support the presence of disparity cells in the visual cortex and show that these cells surface as a result of binocular stimulation received after birth. Therefore, creating in hardware cells that can learn different disparities with experience not only is novel but also is biologically more realistic. These disparity cells, when allowed to interact diffusively on a larger scale, can be used to adaptively create stable topological disparity maps in silicon. PMID:27243029

Background Little is understood about racial/ethnic disparities in infant health in South America. We quantified the extent to which the disparity in preterm birth rate (PTB; < 37 gestational weeks) between infants of Native only ancestry and those of European only ancestry in Argentina and Ecuador are explained by household socioeconomic, demographic, healthcare use, and geographic location indicators. Methods The samples included 5199 infants born between 2000 and 2011 from Argentina and 1579 infants born between 2001 and 2011 from Ecuador. An Oaxaca-Blinder type decomposition model adapted to binary outcomes was estimated to explain the disparity in PTB risk across groups of variables and specific variables. Results Maternal use of prenatal care services significantly explained the PTB disparity, by nearly 57% and 30% in Argentina and Ecuador, respectively. Household socioeconomic status explained an additional 26% of the PTB disparity in Argentina. Conclusions Differences in maternal use of prenatal care may partly explain ethnic disparities in PTB in Argentina and Ecuador. Improving access to prenatal care may reduce ethnic disparities in PTB risk in these countries. PMID:27875924

Purpose Epidemiologists have long contributed to policy efforts to address health disparities. Three examples illustrate how epidemiologists have addressed health disparities in the U.S. and abroad through a “social determinants of health” lens. Methods To identify examples of how epidemiologic research has been applied to reduce health disparities, we queried epidemiologists engaged in disparities research in the U.S., Canada, and New Zealand, and drew upon the scientific literature. Results Resulting examples covered a wide range of topic areas. Three areas selected for their contributions to policy were: 1) epidemiology's role in definition and measurement, 2) the study of housing and asthma, and 3) the study of food policy strategies to reduce health disparities. While epidemiologic research has done much to define and quantify health inequalities, it has generally been less successful at producing evidence that would identify targets for health equity intervention. Epidemiologists have a role to play in measurement and basic surveillance, etiologic research, intervention research, and evaluation research. However, our training and funding sources generally place greatest emphasis on surveillance and etiologic research. Conclusions: The complexity of health disparities requires better training for epidemiologists to effectively work in multidisciplinary teams. Together we can evaluate contextual and multilevel contributions to disease and study intervention programs in order to gain better insights into evidenced-based health equity strategies.

Disparities in health care and health outcomes are a significant problem in the United States. Delivery system reforms such as the patient-centered medical home (PCMH) could have important implications for disparities. To investigate what role disparities play in current PCMH initiatives and how their set-up might impact on disparities. We selected 4 state-based PCMH initiatives (Colorado, Massachusetts, Pennsylvania, and Rhode Island), 1 regional initiative in New Orleans, and 1 multistate initiative. We interviewed 30 key actors in these initiatives and 3 health policy experts on disparities in the context of PCMH. Interview data were coded using the constant comparative method. We find that disparities are not an explicit priority in PCMH initiatives. Nevertheless, many policymakers, providers, and initiative leaders believe that the model has the potential to reduce disparities. However, because of the funding structure of initiatives and the lack of adjustment of quality metrics, health policy experts do not share this optimism and safety-net providers report concerns and frustration. Even though disparities are currently not a priority in the PCMH community, the design of initiatives has important implications for disparities.

Cooperative Learning in Reservoir Simulation Classes: Overcoming Disparate Entry Skills

NASA Astrophysics Data System (ADS)

Awang, Mariyamni

2006-10-01

Reservoir simulation is one of the core courses in the petroleum engineering curriculum and it requires knowledge and skills in three major disciplines, namely programming, numerical methods and reservoir engineering. However, there were often gaps in the students' readiness to undertake the course, even after completing the necessary requirements. The disparate levels of competency of the good and poor students made it difficult to target a certain level. Cooperative learning in the form of projects and peer teaching was designed to address the major concern of disparate entry skills, and at the same time the method used should also succeed in keeping students interest in class, developing communication skills and improving self-learning. Slower and weaker students were expected to benefit from being taught by good students, who were better prepared, and good students would gain deeper comprehension of the subject matter. From evaluations, the approach was considered successful since the overall passing rate was greater than 95% compared to previous years of around 70-80%. It had also succeeded in improving the learning environment in class. Future simulation classes will continue to use the cooperative approach with minor adjustments.

Development and implementation of effective, sustainable, and scalable interventions that advance equity could be propelled by innovative and inclusive partnerships. Readied catalytic frameworks that foster communication, collaboration, a shared vision, and transformative translational research across scientific and non-scientific divides are needed to foster rapid generation of novel solutions to address and ultimately eliminate disparities. To achieve this, we transformed and expanded a community-academic board into a translational science board with members from public, academic and private sectors. Rooted in team science, diverse board experts formed topic-specific “accelerators”, tasked with collaborating to rapidly generate new ideas, questions, approaches, and projects comprising patients, advocates, clinicians, researchers, funders, public health and industry leaders. We began with four accelerators—digital health, big data, genomics and environmental health—and were rapidly able to respond to funding opportunities, transform new ideas into clinical and community programs, generate new, accessible, actionable data, and more efficiently and effectively conduct research. This innovative model has the power to maximize research quality and efficiency, improve patient care and engagement, optimize data democratization and dissemination among target populations, contribute to policy, and lead to systems changes needed to address the root causes of disparities.

There is evidence of health disparities between sexual minority and heterosexual populations. Although the focus of lesbian, gay, bisexual, and transgender health research has been human immunodeficiency virus/acquired immunodeficiency syndrome and sexually transmitted infection among men who have sex with men, there are health disparities among sexual minority women. Using the minority stress framework, these disparities may in part be caused by individual prejudice, social stigma, and discrimination. To ensure equitable health for all, there is urgent need for targeted culturally sensitive health promotion, cultural sensitivity training for health care providers, and intervention-focused research.

In 2005, the Robert Wood Johnson Foundation created Finding Answers: Disparities Research for Change, a program to identify, evaluate, and disseminate interventions to reduce racial and ethnic disparities in the care and outcomes of patients with cardiovascular disease, depression, and diabetes. In this introductory paper, we present a conceptual model for interventions that aim to reduce disparities. With this model as a framework, we summarize the key findings from the six other papers in this supplement on cardiovascular disease, diabetes, depression, breast cancer, interventions using cultural leverage, and pay-for-performance and public reporting of performance measures. Based on these findings, we present global conclusions regarding the current state of health disparities interventions and make recommendations for future interventions to reduce disparities. Multifactorial, culturally tailored interventions that target different causes of disparities hold the most promise, but much more research is needed to investigate potential solutions and their implementation.

Why should we investigate the morphological disparity of plant clades?

PubMed Central

Oyston, Jack W.; Hughes, Martin; Gerber, Sylvain; Wills, Matthew A.

2016-01-01

Background Disparity refers to the morphological variation in a sample of taxa, and is distinct from diversity or taxonomic richness. Diversity and disparity are fundamentally decoupled; many groups attain high levels of disparity early in their evolution, while diversity is still comparatively low. Diversity may subsequently increase even in the face of static or declining disparity by increasingly fine sub-division of morphological ‘design’ space (morphospace). Many animal clades reached high levels of disparity early in their evolution, but there have been few comparable studies of plant clades, despite their profound ecological and evolutionary importance. This study offers a prospective and some preliminary macroevolutionary analyses. Methods Classical morphometric methods are most suitable when there is reasonable conservation of form, but lose traction where morphological differences become greater (e.g. in comparisons across higher taxa). Discrete character matrices offer one means to compare a greater diversity of forms. This study explores morphospaces derived from eight discrete data sets for major plant clades, and discusses their macroevolutionary implications. Key Results Most of the plant clades in this study show initial, high levels of disparity that approach or attain the maximum levels reached subsequently. These plant clades are characterized by an initial phase of evolution during which most regions of their empirical morphospaces are colonized. Angiosperms, palms, pines and ferns show remarkably little variation in disparity through time. Conifers furnish the most marked exception, appearing at relatively low disparity in the latest Carboniferous, before expanding incrementally with the radiation of successive, tightly clustered constituent sub-clades. Conclusions Many cladistic data sets can be repurposed for investigating the morphological disparity of plant clades through time, and offer insights that are complementary to more focused

2017-07-01

To examine how disparities in adult disability by educational attainment vary across US states. We used the nationally representative data of more than 6 million adults aged 45 to 89 years in the 2010-2014 American Community Survey. We defined disability as difficulty with activities of daily living. We categorized education as low (less than high school), mid (high school or some college), or high (bachelor's or higher). We estimated age-standardized disability prevalence by educational attainment and state. We assessed whether the variation in disability across states occurs primarily among low-educated adults and whether it reflects the socioeconomic resources of low-educated adults and their surrounding contexts. Disparities in disability by education vary markedly across states-from a 20 percentage point disparity in Massachusetts to a 12-point disparity in Wyoming. Disparities vary across states mainly because the prevalence of disability among low-educated adults varies across states. Personal and contextual socioeconomic resources of low-educated adults account for 29% of the variation. Efforts to reduce disparities in disability by education should consider state and local strategies that reduce poverty among low-educated adults and their surrounding contexts.

Research and action to address social disparities in cancer requires clarity about what constitutes and causes these persistent and onerous inequities in health. Currently, both scientific literature and government documents exhibit important disagreements, confused terminology, and considerable, if not deliberate, vagueness about the meaning of the phrase 'cancer disparities' and the related term 'social disparities in health.' This article accordingly reviews critical issues relevant to cohering understanding of what is meant by 'cancer disparities;' offers a definition premised on the causal contention that social disparities in health, by definition, arise from social inequity; and considers its implications for developing a multidisciplinary research agenda on social inequalities in cancer. Tackling this issue will require rigorous and critical frameworks, questions, and methods derived from multiple disciplines, and will necessarily involve epidemiologic, clinical, and intervention research, both quantitative and qualitative. At issue is making conscious research choices: about which types of disparities we study, in relation to which aspect of cancer, so as to improve the likelihood our research will help inform a society-wide discourse about the extent, origins of, and remedies for social injustices in cancer, thereby aiding efforts to eliminate social inequalities in health.

Objective To review methods of measuring racial/ethnic health care disparities. Study Design Identification and tracking of racial/ethnic disparities in health care will be advanced by application of a consistent definition and reliable empirical methods. We have proposed a definition of racial/ethnic health care disparities based in the Institute of Medicine's (IOM) Unequal Treatment report, which defines disparities as all differences except those due to clinical need and preferences. After briefly summarizing the strengths and critiques of this definition, we review methods that have been used to implement it. We discuss practical issues that arise during implementation and expand these methods to identify sources of disparities. We also situate the focus on methods to measure racial/ethnic health care disparities (an endeavor predominant in the United States) within a larger international literature in health outcomes and health care inequality. Empirical Application We compare different methods of implementing the IOM definition on measurement of disparities in any use of mental health care and mental health care expenditures using the 2004–2008 Medical Expenditure Panel Survey. Conclusion Disparities analysts should be aware of multiple methods available to measure disparities and their differing assumptions. We prefer a method concordant with the IOM definition.

Current approaches to health care quality have failed to reduce health care disparities. Despite dramatic increases in the use of quality measurement and associated payment policies, there has been no notable implementation of measurement strategies to reduce health disparities. The National Quality Forum developed a road map to demonstrate how measurement and associated policies can contribute to eliminating disparities and promote health equity. Specifically, the road map presents a four-part strategy whose components are identifying and prioritizing areas to reduce health disparities, implementing evidence-based interventions to reduce disparities, investing in the development and use of health equity performance measures, and incentivizing the reduction of health disparities and achievement of health equity. To demonstrate how the road map can be applied, we present an example of how measurement and value-based payment can be used to reduce racial disparities in hypertension among African Americans.

Compared to European-Americans, African-Americans have greater probability of becoming infected with HIV, as well as worse outcomes when they become infected. Therefore, adequate health communications should ensure that they capture the attention of African-Americans and do not perpetuate disadvantages relative to European-Americans. The objective of this report was to examine if racial disparities in attention to health information parallel racial disparities in health outcomes. Participants were clients of a public health clinic (Study 1 n = 64; Study 2 n = 55). Unobtrusive observation in a public health waiting room, message reading times, and response-time on a modified flanker task were used to examine attention to HIV- and flu-information across racial groups. In Study 1, participants were observed for the duration of their time in a public health clinic waiting room (average duration 31 minutes). In Study 2, participants completed tasks in a private room at the public health clinic (average duration 21 minutes). Across all attention measures, results suggest an interaction between race and information type on attention to health information. In particular, African-Americans differentially attended to information as a function of information type, with decreased attention to HIV versus flu information. In contrast, European-Americans attended equally to both HIV and flu information. As such, disparities in attention yielded less access to certain health information for African- than European-Americans in a health setting. The identified disparities in attention are particularly problematic because they disadvantage African-Americans at a time of great effort to correct racial disparities. Modifying the framing of health information in ways that ensure attention by all racial groups may be a strategy to increase attention, and thereby reduce disparities in health outcomes. Future research should find solutions that increase attentional access to health

Objectives To determine the contribution of progress in averting premature deaths to the increase in life expectancy and the decline in lifespan variation. Design International comparison of national life table data from the Human Mortality Database. Setting 40 developed countries and regions, 1840–2009. Population Men and women of all ages. Main outcome measure We use two summary measures of mortality: life expectancy and life disparity. Life disparity is a measure of how much lifespans differ among individuals. We define a death as premature if postponing it to a later age would decrease life disparity. Results In 89 of the 170 years from 1840 to 2009, the country with the highest male life expectancy also had the lowest male life disparity. This was true in 86 years for female life expectancy and disparity. In all years, the top several life expectancy leaders were also the top life disparity leaders. Although only 38% of deaths were premature, fully 84% of the increase in life expectancy resulted from averting premature deaths. The reduction in life disparity resulted from reductions in early-life disparity, that is, disparity caused by premature deaths; late-life disparity levels remained roughly constant. Conclusions The countries that have been the most successful in averting premature deaths have consistently been the life expectancy leaders. Greater longevity and greater equality of individuals' lifespans are not incompatible goals. Countries can achieve both by reducing premature deaths. PMID:22021770

The prevalence of childhood obesity is significantly higher among racial and/or ethnic minority children in the United States. It is unclear to what extent well-established obesity risk factors in infancy and preschool explain these disparities. Our objective was to decompose racial and/or ethnic disparities in children's weight status according to contributing socioeconomic and behavioral risk factors. We used nationally representative data from ∼10 700 children in the Early Childhood Longitudinal Study Birth Cohort who were followed from age 9 months through kindergarten entry. We assessed the contribution of socioeconomic factors and maternal, infancy, and early childhood obesity risk factors to racial and/or ethnic disparities in children's BMI z scores by using Blinder-Oaxaca decomposition analyses. The prevalence of risk factors varied significantly by race and/or ethnicity. African American children had the highest prevalence of risk factors, whereas Asian children had the lowest prevalence. The major contributor to the BMI z score gap was the rate of infant weight gain during the first 9 months of life, which was a strong predictor of BMI z score at kindergarten entry. The rate of infant weight gain accounted for between 14.9% and 70.5% of explained disparities between white children and their racial and/or ethnic minority peers. Gaps in socioeconomic status were another important contributor that explained disparities, especially those between white and Hispanic children. Early childhood risk factors, such as fruit and vegetable consumption and television viewing, played less important roles in explaining racial and/or ethnic differences in children's BMI z scores. Differences in rapid infant weight gain contribute substantially to racial and/or ethnic disparities in obesity during early childhood. Interventions implemented early in life to target this risk factor could help curb widening racial and/or ethnic disparities in early childhood obesity

Binocular disparity provides a powerful cue for depth perception in a stereoscopic environment. Despite increasing knowledge of the cortical areas that process disparity from neuroimaging studies, the neural mechanism underlying disparity sign processing [crossed disparity (CD)/uncrossed disparity (UD)] is still poorly understood. In the present study, functional magnetic resonance imaging (fMRI) was used to explore different neural features that are relevant to disparity-sign processing. We performed an fMRI experiment on 27 right-handed healthy human volunteers by using both general linear model (GLM) and multi-voxel pattern analysis (MVPA) methods. First, GLM was used to determine the cortical areas that displayed different responses to different disparity signs. Second, MVPA was used to determine how the cortical areas discriminate different disparity signs. The GLM analysis results indicated that shapes with UD induced significantly stronger activity in the sub-region (LO) of the lateral occipital cortex (LOC) than those with CD. The results of MVPA based on region of interest indicated that areas V3d and V3A displayed higher accuracy in the discrimination of crossed and uncrossed disparities than LOC. The results of searchlight-based MVPA indicated that the dorsal visual cortex showed significantly higher prediction accuracy than the ventral visual cortex and the sub-region LO of LOC showed high accuracy in the discrimination of crossed and uncrossed disparities. The results may suggest the dorsal visual areas are more discriminative to the disparity signs than the ventral visual areas although they are not sensitive to the disparity sign processing. Moreover, the LO in the ventral visual cortex is relevant to the recognition of shapes with different disparity signs and discriminative to the disparity sign.

Stereomotion speed perception: contributions from both changing disparity and interocular velocity difference over a range of relative disparities

NASA Technical Reports Server (NTRS)

Brooks, Kevin R.; Stone, Leland S.

2004-01-01

The role of two binocular cues to motion in depth-changing disparity (CD) and interocular velocity difference (IOVD)- was investigated by measuring stereomotion speed discrimination and static disparity discrimination performance (stereoacuity). Speed discrimination thresholds were assessed both for random dot stereograms (RDS), and for their temporally uncorrelated equivalents, dynamic random dot stereograms (DRDS), at relative disparity pedestals of -19, 0, and +19 arcmin. While RDS stimuli contain both CD and IOVD cues, DRDS stimuli carry only CD information. On average, thresholds were a factor of 1.7 higher for DRDS than for RDS stimuli with no clear effect of relative disparity pedestal. Results were similar for approaching and receding targets. Variations in stimulus duration had no significant effect on thresholds, and there was no observed correlation between stimulus displacement and perceived speed, confirming that subjects responded to stimulus speed in each condition. Stereoacuity was equally good for our RDS and DRDS stimuli, showing that the difference in stereomotion speed discrimination performance for these stimuli was not due to any difference in the precision of the disparity cue. In addition, when we altered stereomotion stimulus trajectory by independently manipulating the speeds and directions of its monocular half-images, perceived stereomotion speed remained accurate. This finding is inconsistent with response strategies based on properties of either monocular half-image motion, or any ad hoc combination of the monocular speeds. We conclude that although subjects are able to discriminate stereomotion speed reliably on the basis of CD information alone, IOVD provides a precise additional cue to stereomotion speed perception.

Racial and ethnic disparities in antidepressant drug use.

Little is known about racial and ethnic disparities in health care utilization, expenditures and drug choice in the antidepressant market. This study investigates factors associated with the racial and ethnic disparities in antidepressant drug use. We seek to determine the extent to which disparities reflect differences in observable population characteristics versus heterogeneity across racial and ethnic groups. Among the population characteristics, we are interested in identifying which factors are most important in accounting for racial and ethnic disparities in antidepressant drug use. Using Medical Expenditure Panel Survey (MEPS) data from 1996-2003, we have an available sample of 10,416 Caucasian, 1,089 African American and 1,539 Hispanic antidepressant drug users aged 18 to 64 years. We estimate individual out-of-pocket payments, total prescription drug expenditures, drug utilization, the probability of taking generic versus brand name antidepressants, and the share of drugs that are older types of antidepressants (e.g., TCAs and MAOIs) for these individuals during a calendar year. Blinder-Oaxaca decomposition techniques are employed to determine the extent to which disparities reflect differences in observable population characteristics versus unobserved heterogeneity across racial and ethnic groups. Caucasians have the highest antidepressant drug expenditures and utilization. African-Americans have the lowest drug expenditures and Hispanics have the lowest drug utilization. Relative to Caucasians and Hispanics, African-Americans are more likely to purchase generics and use a higher share of older drugs (e.g., TCAs and MAOIs). Differences in observable characteristics explain most of the racial/ethnic differences in these outcomes, with the exception of drug utilization. Differences in health insurance and education levels are particularly important factors in explaining disparities. In contrast, differences in drug utilization largely reflect unobserved

This paper presents an architecture for computing vector disparity for active vision systems as used on robotics applications. The control of the vergence angle of a binocular system allows us to efficiently explore dynamic environments, but requires a generalization of the disparity computation with respect to a static camera setup, where the disparity is strictly 1-D after the image rectification. The interaction between vision and motor control allows us to develop an active sensor that achieves high accuracy of the disparity computation around the fixation point, and fast reaction time for the vergence control. In this contribution, we address the development of a real-time architecture for vector disparity computation using an FPGA device. We implement the disparity unit and the control module for vergence, version, and tilt to determine the fixation point. In addition, two on-chip different alternatives for the vector disparity engines are discussed based on the luminance (gradient-based) and phase information of the binocular images. The multiscale versions of these engines are able to estimate the vector disparity up to 32 fps on VGA resolution images with very good accuracy as shown using benchmark sequences with known ground-truth. The performances in terms of frame-rate, resource utilization, and accuracy of the presented approaches are discussed. On the basis of these results, our study indicates that the gradient-based approach leads to the best trade-off choice for the integration with the active vision system.

Why should we investigate the morphological disparity of plant clades?

PubMed

Oyston, Jack W; Hughes, Martin; Gerber, Sylvain; Wills, Matthew A

2016-04-01

Disparity refers to the morphological variation in a sample of taxa, and is distinct from diversity or taxonomic richness. Diversity and disparity are fundamentally decoupled; many groups attain high levels of disparity early in their evolution, while diversity is still comparatively low. Diversity may subsequently increase even in the face of static or declining disparity by increasingly fine sub-division of morphological 'design' space (morphospace). Many animal clades reached high levels of disparity early in their evolution, but there have been few comparable studies of plant clades, despite their profound ecological and evolutionary importance. This study offers a prospective and some preliminary macroevolutionary analyses. Classical morphometric methods are most suitable when there is reasonable conservation of form, but lose traction where morphological differences become greater (e.g. in comparisons across higher taxa). Discrete character matrices offer one means to compare a greater diversity of forms. This study explores morphospaces derived from eight discrete data sets for major plant clades, and discusses their macroevolutionary implications. Most of the plant clades in this study show initial, high levels of disparity that approach or attain the maximum levels reached subsequently. These plant clades are characterized by an initial phase of evolution during which most regions of their empirical morphospaces are colonized. Angiosperms, palms, pines and ferns show remarkably little variation in disparity through time. Conifers furnish the most marked exception, appearing at relatively low disparity in the latest Carboniferous, before expanding incrementally with the radiation of successive, tightly clustered constituent sub-clades. Many cladistic data sets can be repurposed for investigating the morphological disparity of plant clades through time, and offer insights that are complementary to more focused morphometric studies.

While reducing racial/ethnic and socioeconomic disparities in cancer mortality has been identified as a national goal, current policies are unlikely to achieve it. In order to advance the development of policies for the primary prevention of cancer and cancer disparities, we propose that the practices of the tobacco, alcohol, and food industries be considered as modifiable social determinants of health. We review evidence that the practices of these industries in product design, marketing, retail distribution, and pricing contribute to cancer risk behavior, incidence, and disparities, then examine public health strategies designed to reduce health-damaging practices of these industries and encourage healthier alternatives. We conclude with recommendations for research, practice, and policy that could contribute to the development of less carcinogenic corporate practices.

Recurrent connectivity can account for the dynamics of disparity processing in V1

Samonds, Jason M.; Potetz, Brian R.; Tyler, Christopher W.; Lee, Tai Sing

2013-01-01

Disparity tuning measured in the primary visual cortex (V1) is described well by the disparity energy model, but not all aspects of disparity tuning are fully explained by the model. Such deviations from the disparity energy model provide us with insight into how network interactions may play a role in disparity processing and help to solve the stereo correspondence problem. Here, we propose a neuronal circuit model with recurrent connections that provides a simple account of the observed deviations. The model is based on recurrent connections inferred from neurophysiological observations on spike timing correlations, and is in good accord with existing data on disparity tuning dynamics. We further performed two additional experiments to test predictions of the model. First, we increased the size of stimuli to drive more neurons and provide a stronger recurrent input. Our model predicted sharper disparity tuning for larger stimuli. Second, we displayed anti-correlated stereograms, where dots of opposite luminance polarity are matched between the left- and right-eye images and result in inverted disparity tuning in the disparity energy model. In this case, our model predicted reduced sharpening and strength of inverted disparity tuning. For both experiments, the dynamics of disparity tuning observed from the neurophysiological recordings in macaque V1 matched model simulation predictions. Overall, the results of this study support the notion that, while the disparity energy model provides a primary account of disparity tuning in V1 neurons, neural disparity processing in V1 neurons is refined by recurrent interactions among elements in the neural circuit.

Integrating intersectionality and biomedicine in health disparities research.

PubMed

Kelly, Ursula A

2009-01-01

Persisting health disparities have lead to calls for an increase in health research to address them. Biomedical scientists call for research that stratifies individual indicators associated with health disparities, for example, ethnicity. Feminist social scientists recommend feminist intersectionality research. Intersectionality is the multiplicative effect of inequalities experienced by nondominant marginalized groups, for example, ethnic minorities, women, and the poor. The elimination of health disparities necessitates integration of both paradigms in health research. This study provides a practical application of the integration of biomedical and feminist intersectionality paradigms in nursing research, using a psychiatric intervention study with battered Latino women as an example.

This supplement is the second CDC Health Disparities and Inequalities Report (CHDIR). The 2011 CHDIR was the first CDC report to assess disparities across a wide range of diseases, behavioral risk factors, environmental exposures, social determinants, and health-care access (CDC. CDC Health Disparities and Inequalities Report-United States, 2011. MMWR 2011;60[Suppl; January 14, 2011]). The 2013 CHDIR provides new data for 19 of the topics published in 2011 and 10 new topics. When data were available and suitable analyses were possible for the topic area, disparities were examined for population characteristics that included race and ethnicity, sex, sexual orientation, age, disability, socioeconomic status, and geographic location. The purpose of this supplement is to raise awareness of differences among groups regarding selected health outcomes and health determinants and to prompt actions to reduce disparities. The findings in this supplement can be used by practitioners in public health, academia and clinical medicine; the media; the general public; policymakers; program managers; and researchers to address disparities and help all persons in the United States live longer, healthier, and more productive lives.

The goals of this special section are to examine the state-of-the-science regarding race/ethnicity and racism as they contribute to health disparities and to articulate a research agenda to guide future research. In the first paper, Myers presents an integrative theoretical framework for understanding how racism, poverty, and other major stressors relate to health through inter-related psychosocial and bio-behavioral pathways. Williams and Mohammed review the evidence concerning associations between racism and health, addressing the multiple levels at which racism can operate and commenting on important methodological issues. Klonoff provides a review and update of the literature concerning ethnicity-related disparities in healthcare, and addresses factors that may contribute to these disparities. Brondolo and colleagues consider racism from a stress and coping perspective, and review the literature concerning racial identity, anger coping, and social support as potential moderators of the racism-health association. Finally, Castro and colleagues describe an ecodevelopmental model that can serve as an integrative framework to examine multi-level social-cultural influences on health and health behavior. In aggregate, the special section papers address theoretical and methodological issues central to understanding the determinants of health disparities, with the aim of providing direction for future research critical to developing effective interventions to reduce these disparities.

One of the challenges of healthcare data processing, analysis and warehousing is the integration of data gathered from disparate and diverse data sources. Promoting the adoption of worldwide accepted information standards along with common terminologies and the use of technologies derived from semantic web representation, is a suitable path to achieve that. To that end, the HL7 V3 Reference Information Model (RIM) [1] has been used as the underlying information model coupled with the Web Ontology Language (OWL) [2] as the semantic data integration technology. In this paper we depict a biomedical data integration process and demonstrate how it was used for integrating various data sources, containing clinical, environmental and genomic data, within Hypergenes, a European Commission funded project exploring the Essential Hypertension [3] disease model.

Uneven Magnitude of Disparities in Cancer Risks from Air Toxics

This study examines race- and income-based disparities in cancer risks from air toxics in Cancer Alley, LA, USA. Risk estimates were obtained from the 2005 National Air Toxics Assessment and socioeconomic and race data from the 2005 American Community Survey, both at the census tract level. Disparities were assessed using spatially weighted ordinary least squares (OLS) regression and quantile regression (QR) for five major air toxics, each with cancer risk greater than 10−6. Spatial OLS results showed that disparities in cancer risks were significant: People in low-income tracts bore a cumulative risk 12% more than those in high-income tracts (p < 0.05), and those in black-dominant areas 16% more than in white-dominant areas (p < 0.01). Formaldehyde and benzene were the two largest contributors to the disparities. Contributions from emission sources to disparities varied by compound. Spatial QR analyses showed that magnitude of disparity became larger at the high end of exposure range, indicating worsened disparity in the poorest and most highly concentrated black areas. Cancer risk of air toxics not only disproportionately affects socioeconomically disadvantaged and racial minority communities, but there is a gradient effect within these groups with poorer and higher minority concentrated segments being more affected than their counterparts. Risk reduction strategies should target emission sources, risk driver chemicals, and especially the disadvantaged neighborhoods. PMID:23208297

Significant disparities in CKD rates and outcomes exist between black and white Americans. Health disparities are defined as health differences that adversely affect disadvantaged populations, on the basis of one or more health outcomes. CKD is the complex result of genetic and environmental factors, reflecting the balance of nature and nurture. Social determinants of health have an important role as environmental components, especially for black populations, who are disproportionately disadvantaged. Understanding the social determinants of health and appreciating the underlying differences associated with meaningful clinical outcomes may help nephrologists treat all their patients with CKD in an optimal manner. Altering the social determinants of health, although difficult, may embody important policy and research efforts, with the ultimate goal of improving outcomes for patients with kidney diseases, and minimizing the disparities between groups.

Clinical treatment guidelines have suggested that laparoscopic hernia repair should be the preferred approach in both men and women with bilateral or recurrent elective groin hernias. Anecdotal evidence suggests, however, that women are less likely to undergo a laparoscopic repair than men, and therefore, we aimed to delineate if these disparities persisted after controlling for patient factors and comorbidities. The American College of Surgeons National Surgical Quality Improvement Project data were abstracted for all elective groin hernia repairs between 2005 and 2014. Univariate analysis was used to compare rates of laparoscopic surgery between men and women. Multivariable analysis was performed, controlling for patient demographics, preoperative comorbidities, and year of surgery. Over the 10-y period, 141,490 patients underwent elective groin hernia repair, of which 13,325 were women (9.4%). The rate of general anesthesia utilization was high in both men (81.3%) and women (77.2%) with 75.1% of open repairs being performed under general anesthesia. Overall, 20.2% of women underwent laparoscopic repair compared with 28.0% of men (P < 0.01). Women tended to be older, had a lesser body mass index, and slightly greater American Anesthesia Association (all P < 0.05). On multivariable regression, women had decreased odds of undergoing a laparoscopic approach compared with men (odds ratio: 0.70; 95% confidence interval, 0.67-0.73, P < 0.01). In the elective setting, women were less likely to undergo laparoscopic repair of groin hernias than men. Although we are unable to ascertain underlying causes for these gender disparities, these data suggest that there remains a disparity in the management of groin hernias in women.

Oral health disparities and the workforce: a framework to guide innovation.

PubMed

Hilton, Irene V; Lester, Arlene M

2010-06-01

Oral health disparities currently exist in the United States, and workforce innovations have been proposed as one strategy to address these disparities. A framework is needed to logically assess the possible role of workforce as a contributor to and to analyze workforce strategies addressing the issue of oral health disparities. Using an existing framework, A Strategic Framework for Improving Racial/Ethnic Minority Health and Eliminating Racial/Ethnic Health Disparities, workforce was sequentially applied across individual, environmental/community, and system levels to identify long-term problems, contributing factors, strategies/innovation, measurable outcomes/impacts, and long-term goals. Examples of current workforce innovations were applied to the framework. Contributing factors to oral health disparities included lack of racial/ethnic diversity of the workforce, lack of appropriate training, provider distribution, and a nonuser-centered system. The framework was applied to selected workforce innovation models delineating the potential impact on contributing factors across the individual, environmental/community, and system levels. The framework helps to define expected outcomes from workforce models that would contribute to the goal of reducing oral health disparities and examine impacts across multiple levels. However, the contributing factors to oral health disparities cannot be addressed by workforce innovation alone. The Strategic Framework is a logical approach to guide workforce innovation, solutions, and identification of other aspects of the oral healthcare delivery system that need innovation in order to reduce oral health disparities.

In the USA, race and socioeconomic status are well-known factors associated with colorectal cancer incidence and mortality rates. These are higher among blacks than whites and other racial/ethnic groups. In this article, we review opportunities to address disparities in colorectal cancer incidence, mortality, and survivorship among African Americans. First, we summarize the primary prevention of colorectal cancer and recent advances in the early detection of the disease and disparities in screening. Then, we consider black-white disparities in colorectal cancer treatment and survival including factors that may contribute to such disparities and the important roles played by cultural competency, patient trust in one's physician, and health literacy in addressing colorectal cancer disparities, including the need for studies involving the use of colorectal cancer patient navigators who are culturally competent. To reduce these disparities, intervention efforts should focus on providing high-quality screening and treatment for colorectal cancer and on educating African Americans about the value of diet, weight control, screening, and treatment. Organized approaches for delivering colorectal cancer screening should be accompanied by programs and policies that provide access to diagnostic follow-up and treatment for underserved populations.

2014-01-01

Ocular inflammatory disorders disproportionately affect women, and the majority of affected women are of childbearing age. The role of sex or reproductive hormones has been proposed in many other inflammatory or autoimmune disorders, and findings from non-ocular autoimmune diseases suggest a complex interaction between sex hormones, genetic factors and the immune system. However, despite the age and sex bias, factors that influence this disparity are complicated and unclear. This review aims to evaluate the gender disparities in prevalence, incidence and severity of the most common infectious and non-infectious ocular inflammatory disorders. PMID:24987987

2014-01-01

Health disparities are prevalent across diseases of the respiratory system, and are major sources of morbidity and mortality among disadvantaged populations in the United States. The American Thoracic Society (ATS) aims to reduce disparities that are both avoidable and unjust. In meeting this goal, the ATS is committed to creating the Lung Corps, a diverse group of senior, mid-level, and junior clinicians, trainees, researchers, and public health practitioners to help achieve health equality. This will be achieved through the following mechanisms: (1) increase awareness of health disparities; (2) empower health professionals with the knowledge and tools to address disparities; (3) shape research agendas to focus on the root causes, to identify modifiable targets, and to promote innovative approaches to reduce disparities; and (4) develop and advocate for health-related policies and regulations that improve the respiratory health of the population. To ensure success, the Lung Corps will interact with other societies, agencies, and organizations to effect elimination of disparities in respiratory health. The ATS is committed to identifying and addressing health disparities to improve the overall health of individuals affected by respiratory diseases. PMID:24697756

Mind the gap: race/ethnic and socioeconomic disparities in obesity.

Race/ethnic and socioeconomic status (SES) disparities in obesity are substantial and may widen in the future. We review nine potential mechanisms that recent research has used to explain obesity disparities. Those nine mechanisms fall into three broad groups-health behaviors, biological factors, and the social environment-which incorporate both proximate and upstream determinants of obesity disparities. Efforts to reduce the prevalence of obesity in the US population and to close race/ethnic and SES disparities in obesity will likely require the use of multifaceted interventions that target multiple mechanisms simultaneously. Unfortunately, relatively few of the mechanisms reviewed herein have been tested in an intervention framework.

BACKGROUND The South Carolina Cancer Prevention and Control Research Network (SC-CPCRN) implemented the Community Health Intervention Program (CHIP) mini-grants initiative to address cancer-related health disparities and reduce the cancer burden among high-risk populations across the state. The mini-grants project implemented evidence-based health interventions tailored to the specific needs of each community. OBJECTIVE To support the SC-CPCRN’s goals of moving toward greater dissemination and implementation of evidence-based programs in the community to improve public health, prevent disease, and reduce the cancer burden. METHODS Three community-based organizations were awarded $10,000 each to implement one of the National Cancer Institute’s evidence-based interventions. Each group had 12 months to complete their project. SC-CPCRN investigators and staff provided guidance, oversight, and technical assistance for each project. Grantees provided regular updates and reports to their SC-CPCRN liaisons to capture vital evaluation information. RESULTS The intended CHIP mini-grant target population reach was projected to be up to 880 participants combined. Actual combined reach of the three projects reported upon completion totaled 1,072 individuals. The majority of CHIP participants were African-American females. Participants ranged in age from 19 to 81 years. Evaluation results showed an increase in physical activity, dietary improvements, and screening participation. CONCLUSIONS The success of the initiative was the result of a strong community-university partnership built on trust. Active two-way communication and an honest open dialogue created an atmosphere for collaboration. Communities were highly motivated. All team members shared a common goal of reducing cancer-related health disparities and building greater public health capacity across the state. PMID:23645547

Controlling disease and creating disparities: a fundamental cause perspective.

PubMed

Phelan, Jo C; Link, Bruce G

2005-10-01

The United States and other developed countries experienced enormous improvements in population health during the 20th century. In the context of this dramatic positive change, health disparities by race and socioeconomic status emerged for several potent killers. Any explanation for current health disparities must take these changing patterns into account. Any explanation that ignores large improvements in population health and fails to account for the emergence of disparities for specific diseases is an inadequate explanation of current disparities. We argue that genetic explanations and some prominent social causation explanations are incompatible with these facts. We propose that the theory of "fundamental causes" can account for both vast improvements in population health and the creation of large socioeconomic and racial disparities in mortality for specific causes of death over time. Specifically, we argue that it is our enormously expanded capacity to control disease and death in combination with existing social and economic inequalities that create health disparities by race and socioeconomic status: When we develop the ability to control disease and death, the benefits of this new-found ability are distributed according to resources of knowledge, money, power, prestige, and beneficial social connections. We present data on changing mortality patterns by race and socioeconomic status for two types of diseases: those for which our capacity to prevent death has increased significantly and those for which we remain largely unable to prevent death. Time trends in mortality patterns are consistent with the fundamental cause explanation.

Employment and Wage Disparities for Nurses With Activity Limitations.

PubMed

Wilson, Barbara L; Butler, Richard J; Butler, Matthew J

2016-11-01

No studies quantify the labor market disparities between nurses with and without activity difficulties (physical impairment or disability). We explore disparate treatment of nurses with activity difficulties at three margins of the labor market: the ability to get a job, the relative wage rate offered once a nurse has a job, and the annual hours of work given that wage rate. Key variables from the American Community Survey (ACS) were analyzed, including basic demographic information, wages, hours of work, and employment status of registered nurses from 2006 to 2014. Although there is relatively little disparity in hourly wages, there is enormous disparity in the disabled's employment and hours of work opportunities, and hence a moderate amount of disparity in annual wages. This has significant implications for the nursing labor force, particularly as the nursing workforce continues to age and physical limitations or disabilities increase by 15-fold from 25 to 65 years of age.  Physical or psychological difficulties increase sharply over the course of a nurse's career, and employers must heighten efforts to facilitate an aging workforce and provide appropriate job accommodations for nurses with activity limitations. © 2016 Sigma Theta Tau International.

Health Disparities and Health Equity: The Issue Is Justice

Eliminating health disparities is a Healthy People goal. Given the diverse and sometimes broad definitions of health disparities commonly used, a subcommittee convened by the Secretary's Advisory Committee for Healthy People 2020 proposed an operational definition for use in developing objectives and targets, determining resource allocation priorities, and assessing progress. Based on that subcommittee's work, we propose that health disparities are systematic, plausibly avoidable health differences adversely affecting socially disadvantaged groups; they may reflect social disadvantage, but causality need not be established. This definition, grounded in ethical and human rights principles, focuses on the subset of health differences reflecting social injustice, distinguishing health disparities from other health differences also warranting concerted attention, and from health differences in general. We explain the definition, its underlying concepts, the challenges it addresses, and the rationale for applying it to United States public health policy. PMID:21551385

Effects of Prism Eyeglasses on Objective and Subjective Fixation Disparity

PubMed Central

Schroth, Volkhard; Joos, Roland; Jaschinski, Wolfgang

2015-01-01

In optometry of binocular vision, the question may arise whether prisms should be included in eyeglasses to compensate an oculomotor and/or sensory imbalance between the two eyes. The corresponding measures of objective and subjective fixation disparity may be reduced by the prisms, or the adaptability of the binocular vergence system may diminish effects of the prisms over time. This study investigates effects of wearing prisms constantly for about 5 weeks in daily life. Two groups of 12 participants received eyeglasses with prisms having either a base-in direction or a base-out direction with an amount up to 8 prism diopters. Prisms were prescribed based on clinical fixation disparity test plates at 6 m. Two dependent variables were used: (1) subjective fixation disparity was indicated by a perceived offset of dichoptic nonius lines that were superimposed on the fusion stimuli and (2) objective fixation disparity was measured with a video based eye tracker relative to monocular calibration. Stimuli were presented at 6 m and included either central or more peripheral fusion stimuli. Repeated measurements were made without the prisms and with the prisms after about 5 weeks of wearing these prisms. Objective and subjective fixation disparity were correlated, but the type of fusion stimulus and the direction of the required prism may play a role. The prisms did not reduce the fixation disparity to zero, but induced significant changes in fixation disparity with large effect sizes. Participants receiving base-out prisms showed hypothesized effects, which were concurrent in both types of fixation disparity. In participants receiving base-in prisms, the individual effects of subjective and objective effects were negatively correlated: the larger the subjective (sensory) effect, the smaller the objective (motor) effect. This response pattern was related to the vergence adaptability, i.e. the individual fusional vergence reserves. PMID:26431525

Abstract To examine racial/ethnic and gender disparities in antiretroviral (ART) use and viral suppression among HIV-infected persons in care and identify factors that might account for observed disparities. The Medical Monitoring Project (MMP) is a complex sample survey of HIV-infected adults receiving medical care in the United States. We used weighted interview and medical record data collected 06/2009 to 05/2012 to estimate the prevalence of ART use and viral suppression among gender-stratified racial/ethnic groups. We used χ2 tests to identify significant differences in outcomes between white men versus other groups, and logistic regression models to identify the most parsimonious set of factors that could account for each observed difference. We found no significant disparity in ART use between white and Hispanic men, and no disparities between white men and white and Hispanic women after adjustment for disease stage, age, and poverty. Disparities in ART use between white men and black persons persisted after adjusting for other factors, but the observed differences were relatively small. Differences in ART use and adherence, demographic characteristics, and social determinants of health such as poverty, education, and insurance accounted for the observed disparities in viral suppression between white men and all groups except black men. In our model, accounting for these factors reduced the prevalence difference in viral suppression between white and black men by almost half. We found that factors associated with disparities differed among men and women of the same race/ethnicity, lending support to the assertion that gender affects access to care and health status among HIV-infected patients. In addition to supporting efforts to increase ART use and adherence among persons living with HIV, our analysis provides evidence for the importance of social determinants of health in understanding racial/ethnic and gender differences in ART use and viral suppression

How will the 'cancer moonshot' impact health disparities?

PubMed

Ramirez, Amelie G; Thompson, Ian M

2017-09-01

In 1971, President Nixon signed into law the National Cancer Act (NCA), colloquially known as the "War on Cancer", which pushed cancer onto the national agenda and is credited for many subsequent increases in the knowledge of the molecular, cellular, and genetic causes and effects of cancer. But even though cancer mortality has declined overall in intervening years after the NCA, cancer health disparities persist in the form of higher cancer incidence and mortality rates among certain cancer types and certain populations. Breast and cervical cancers disproportionately affect African American, Hispanic, and American Indian Women. Colorectal cancer is the second leading cause of death for Latinos (with men and women combined). Forty-five years after the NCA, how will the next enormous cancer initiatives-President Barack Obama's Cancer Moonshot and the All of Us Research Program (formerly the Precision Medicine Initiative Cohort Program)-impact cancer health disparities? The emergence of precision medicine and the sharing of information across sectors are at the heart of these large national initiatives and hold vast potential to address complex health disparities that remain in incidence reporting, incidence, treatment, prognoses, and mortality among certain cancer types and racial/ethnic minorities, including African Americans and Hispanics/Latinos, compared to Whites. But clinical research efforts and data collection have historically lacked diverse representation for various reasons, posing a large risk to these national initiatives in their ability to develop diverse cohorts that adequately represent racial/ethnic minorities. Efforts to reduce disparities and increase diversity in study cohorts have emerged, from patient navigation, to use of mobile technology to collect data, to national consortiums dedicated to including diverse groups, to university training on health disparities. These efforts point to the need for the Cancer Moonshot and precision medicine

Terminator disparity contributes to stereo matching for eye movements and perception.

PubMed

Quaia, Christian; Optican, Lance M; Cumming, Bruce G

2013-11-27

In the context of motion detection, the endings (or terminators) of 1-D features can be detected as 2-D features, affecting the perceived direction of motion of the 1-D features (the barber-pole illusion) and the direction of tracking eye movements. In the realm of binocular disparity processing, an equivalent role for the disparity of terminators has not been established. Here we explore the stereo analogy of the barber-pole stimulus, applying disparity to a 1-D noise stimulus seen through an elongated, zero-disparity, aperture. We found that, in human subjects, these stimuli induce robust short-latency reflexive vergence eye movements, initially in the direction orthogonal to the 1-D features, but shortly thereafter in the direction predicted by the disparity of the terminators. In addition, these same stimuli induce vivid depth percepts, which can only be attributed to the disparity of line terminators. When the 1-D noise patterns are given opposite contrast in the two eyes (anticorrelation), both components of the vergence response reverse sign. Finally, terminators drive vergence even when the aperture is defined by a texture (as opposed to a contrast) boundary. These findings prove that terminators contribute to stereo matching, and constrain the type of neuronal mechanisms that might be responsible for the detection of terminator disparity.

Gender disparities in health care.

PubMed

2012-01-01

The existence of disparities in delivery of health care has been the subject of increased empirical study in recent years. Some studies have suggested that disparities between men and women exist in the diagnoses and treatment of health conditions, and as a result measures have been taken to identify these differences. This article uses several examples to illustrate health care gender bias in medicine. These examples include surgery, peripheral artery disease, cardiovascular disease, critical care, and cardiovascular risk factors. Additionally, we discuss reasons why these issues still occur, trends in health care that may address these issues, and the need for acknowledgement of the current system's inequities in order to provide unbiased care for women in the future. © 2012 Mount Sinai School of Medicine.

Asthma disparities in urban environments.

PubMed

Bryant-Stephens, Tyra

2009-06-01

Asthma continues to disproportionately affect minority and low-income groups, with African American and Latino children who live in low-socioeconomic-status urban environments experiencing higher asthma morbidity and mortality than white children. This uneven burden in asthma morbidity has been ever increasing despite medical advancement. Many factors have contributed to these disparities in the areas of health care inequities, which result in inadequate treatment; poor housing, which leads to increased exposure to asthma allergens; and social and psychosocial stressors, which are often unappreciated. Interventions to reduce individual areas of disparities have had varying successes. Because asthma is a complex disease that affects millions of persons, multifaceted comprehensive interventions that combine all evidence-based successful strategies are essential to finally closing the gap in asthma morbidity.

Examining the Gap: Compensation Disparities between Male and Female Physician Assistants.

PubMed

Smith, Noël; Cawley, James F; McCall, Timothy C

Compensation disparities between men and women have been problematic for decades, and there is considerable evidence that the gap cannot be entirely explained by nongender factors. The current study examined the compensation gap in the physician assistant (PA) profession. Compensation data from 2014 was collected by the American Academy of PAs in 2015. Practice variables, including experience, specialty, and hours worked, were controlled for in an ordinary least-squares sequential regression model to examine whether there remained a disparity in total compensation. In addition, the absolute disparity in compensation was compared with historical data collected by American Academy of PAs over the previous 1.5 decades. Without controlling for practice variables, a total compensation disparity of $16,052 existed between men and women in the PA profession. Even after PA practice variables were controlled for, a total compensation disparity of $9,695 remained between men and women (95% confidence interval, $8,438-$10,952). A 17-year trend indicates the absolute disparity between men and women has not lessened, although the disparity as a percent of male compensation has decreased in recent years. There remain challenges to ensuring pay equality in the PA profession. Even when compensation-relevant factors such as experience, hours worked, specialty, postgraduate training, region, and call are controlled for, there is still a substantial gender disparity in PA compensation. Remedies that may address this pay inequality include raising awareness of compensation disparities, teaching effective negotiation skills, assisting employers as they develop equitable compensation plans, having less reliance on past salary in position negotiation, and professional associations advocating for policies that support equal wages and opportunities, regardless of personal characteristics.

Partnering health disparities research with quality improvement science in pediatrics.

PubMed

Lion, K Casey; Raphael, Jean L

2015-02-01

Disparities in pediatric health care quality are well described in the literature, yet practical approaches to decreasing them remain elusive. Quality improvement (QI) approaches are appealing for addressing disparities because they offer a set of strategies by which to target modifiable aspects of care delivery and a method for tailoring or changing an intervention over time based on data monitoring. However, few examples in the literature exist of QI interventions successfully decreasing disparities, particularly in pediatrics, due to well-described challenges in developing, implementing, and studying QI with vulnerable populations or in underresourced settings. In addition, QI interventions aimed at improving quality overall may not improve disparities, and in some cases, may worsen them if there is greater uptake or effectiveness of the intervention among the population with better outcomes at baseline. In this article, the authors review some of the challenges faced by researchers and frontline clinicians seeking to use QI to address health disparities and propose an agenda for moving the field forward. Specifically, they propose that those designing and implementing disparities-focused QI interventions reconsider comparator groups, use more rigorous evaluation methods, carefully consider the evidence for particular interventions and the context in which they were developed, directly engage the social determinants of health, and leverage community resources to build collaborative networks and engage community members. Ultimately, new partnerships between communities, providers serving vulnerable populations, and QI researchers will be required for QI interventions to achieve their potential related to health care disparity reduction.

Psychiatrists' attitudes toward and awareness about racial disparities in mental health care.

PubMed

Mallinger, Julie B; Lamberti, J Steven

2010-02-01

Psychiatrists may perpetuate racial-ethnic disparities in health care through racially biased, albeit unconscious, behaviors. Changing these behaviors requires that physicians accept that racial-ethnic disparities exist and accept their own contributions to disparities. The purposes of this study were to assess psychiatrists' awareness of racial disparities in mental health care, to evaluate the extent to which psychiatrists believe they contribute to disparities, and to determine psychiatrists' interest in participating in disparities-reduction programs. A random sample of psychiatrists, identified through the American Psychiatric Association's member directory, was invited to complete the online survey. The survey was also distributed to psychiatrists at a national professional conference. Of the 374 respondents, most said they were not familiar or only a little familiar with the literature on racial disparities. Respondents tended to believe that race has a moderate influence on quality of psychiatric care but that race is more influential in others' practices than in their own practices. One-fourth had participated in any type of disparities-reduction program within the past year, and approximately one-half were interested in participating in such a program. Psychiatrists may not recognize the pervasiveness of racial inequality in psychiatric care, and they may attribute racially biased thinking to others but not to themselves. Interventions to eliminate racial-ethnic disparities should focus on revealing and modifying unconscious biases. Lack of physician interest may be one barrier to such interventions.

Clades reach highest morphological disparity early in their evolution

Hughes, Martin; Gerber, Sylvain; Wills, Matthew Albion

2013-01-01

There are few putative macroevolutionary trends or rules that withstand scrutiny. Here, we test and verify the purported tendency for animal clades to reach their maximum morphological variety relatively early in their evolutionary histories (early high disparity). We present a meta-analysis of 98 metazoan clades radiating throughout the Phanerozoic. The disparity profiles of groups through time are summarized in terms of their center of gravity (CG), with values above and below 0.50 indicating top- and bottom-heaviness, respectively. Clades that terminate at one of the “big five” mass extinction events tend to have truncated trajectories, with a significantly top-heavy CG distribution overall. The remaining 63 clades show the opposite tendency, with a significantly bottom-heavy mean CG (relatively early high disparity). Resampling tests are used to identify groups with a CG significantly above or below 0.50; clades not terminating at a mass extinction are three times more likely to be significantly bottom-heavy than top-heavy. Overall, there is no clear temporal trend in disparity profile shapes from the Cambrian to the Recent, and early high disparity is the predominant pattern throughout the Phanerozoic. Our results do not allow us to distinguish between ecological and developmental explanations for this phenomenon. To the extent that ecology has a role, however, the paucity of bottom-heavy clades radiating in the immediate wake of mass extinctions suggests that early high disparity more probably results from the evolution of key apomorphies at the base of clades rather than from physical drivers or catastrophic ecospace clearing.

Objective African Americans are disproportionately diagnosed with schizophrenia, and the factors that contribute to this disparity are poorly understood. This study utilized data from the 1995 MacArthur Violence Risk Assessment Study to examine the impact of racial differences in sociodemographic characteristics, clinical presentation, and research interviewer perceptions of honesty on disparities in the diagnosis of schizophrenia in African Americans. Method African Americans (n = 215) and whites (n = 537) with severe mental illness receiving inpatient care were administered structured diagnostic, sociodemographic, and clinical measures during hospitalization. Assessments of interviewer-perceived honesty during diagnostic interviews were used to characterize interviewer perceptions of the patient, and their impact on racial disparities in the diagnosis of schizophrenia. Results African Americans were over three times as likely to be diagnosed with schizophrenia (n = 97, 45%) compared to whites (n = 101, 19%). Disparities in sociodemographic and clinical characteristics modestly contributed to disparities in diagnostic rates. In contrast, interviewer-perceived honesty proved to be a significant predictor of racial disparities in schizophrenia diagnoses that when accounted for, substantially reduced diagnostic disparities between African Americans and whites. Mediator analyses confirmed that interviewer-perceived honesty was the only consistent mediator of the relationship between race and schizophrenia diagnosis. Conclusions Interviewer perceptions patient honesty are important contributors to disparities in the diagnosis of schizophrenia among African Americans, and may be reflective of poor patient-clinician relationships. Methods of facilitating a trusting relationship between patients and clinicians are needed to improve the assessment and treatment of minorities seeking mental health care. PMID:22751938

There is convincing evidence that racial and ethnic disparities exist in the provision of health care, including the provision of emergency care; and that stereotyping, biases, and uncertainty on the part of health care providers all contribute to unequal treatment. Situations, such as the emergency department (ED), that are characterized by time pressure, incomplete information, and high demands on attention and cognitive resources increase the likelihood that stereotypes and bias will affect diagnostic and treatment decisions. It is likely that there are many as-yet-undocumented disparities in clinical emergency practice. Racial and ethnic disparities may arise in decisions made by out-of-hospital personnel regarding ambulance destination, triage assessments made by nursing personnel, diagnostic testing ordered by physicians or physician-extenders, and in disposition decisions. The potential for disparate treatment includes the timing and intensity of ED therapy as well as patterns of referral, prescription choices, and priority for hospital admission and bed assignment. At a national roundtable discussion, strategies suggested to address these disparities included: increased use of evidence-based clinical guidelines; use of continuous quality improvement methods to document individual and institutional disparities in performance; zero tolerance for stereotypical remarks in the workplace; cultural competence training for emergency providers; increased workforce diversity; and increased epidemiologic, clinical, and services research. Careful scrutiny of the clinical practice of emergency medicine and diligent implementation of strategies to prevent disparities will be required to eliminate the individual behaviors and systemic processes that result in the delivery of disparate care in EDs.

The racial/ethnic composition of our nation is projected to change drastically in the coming decades. It is therefore important that the health professions improve their efforts to provide culturally competent care to all patients. We reviewed literature concerning health care disparities and workforce diversity issues—particularly within the oral health field—and provide a synthesis of recommendations to address these issues. This review is highly relevant to both the medical and public health professions, because they are facing similar disparity and workforce issues. In addition, the recent establishment of relationships between oral health and certain systemic health conditions will elevate oral health promotion and disease prevention as important points of intervention in the quest to improve our nation’s public health.

This study uses data from the Health and Retirement Study and an approach informed by the Biopsychosocial Model of Racism as a Stressor to examine the extent to which SES, stressors, discrimination and neighborhood conditions are mechanisms underlying racial/ethnic disparities in functional limitations among men. Results reveal that racial/ethnic differences in SES, stressors, discrimination and neighborhood conditions—individually and collectively—account for a substantial proportion of racial/ethnic disparities in functional limitations. Findings suggest that the social determinants of health for men of color need to be more seriously considered in investigations of and efforts to address health disparities. PMID:26291191

Studies from four areas of musculoskeletal health care disparities were reviewed to determine the root causes of the disparities and gain insight into measurable interventions. The areas of musculoskeletal health were total joint arthroplasty, amputation for patients with diabetes, rehabilitation of and impairment in patients with stroke, and morbidity associated with unintentional injuries. The Jenkins Model on Health Disparities was used to investigate and rank the contributing causes (socioeconomic status, sociocultural beliefs, racism, biology) of the health care disparities. No single root cause was found for any of the conditions. Thus, all contributing factors must be considered when planning meaningful interventions.

Terminator Disparity Contributes to Stereo Matching for Eye Movements and Perception

PubMed Central

Optican, Lance M.; Cumming, Bruce G.

2013-01-01

In the context of motion detection, the endings (or terminators) of 1-D features can be detected as 2-D features, affecting the perceived direction of motion of the 1-D features (the barber-pole illusion) and the direction of tracking eye movements. In the realm of binocular disparity processing, an equivalent role for the disparity of terminators has not been established. Here we explore the stereo analogy of the barber-pole stimulus, applying disparity to a 1-D noise stimulus seen through an elongated, zero-disparity, aperture. We found that, in human subjects, these stimuli induce robust short-latency reflexive vergence eye movements, initially in the direction orthogonal to the 1-D features, but shortly thereafter in the direction predicted by the disparity of the terminators. In addition, these same stimuli induce vivid depth percepts, which can only be attributed to the disparity of line terminators. When the 1-D noise patterns are given opposite contrast in the two eyes (anticorrelation), both components of the vergence response reverse sign. Finally, terminators drive vergence even when the aperture is defined by a texture (as opposed to a contrast) boundary. These findings prove that terminators contribute to stereo matching, and constrain the type of neuronal mechanisms that might be responsible for the detection of terminator disparity. PMID:24285893

Sequist, Thomas D; Schneider, Eric C

2006-01-01

To reduce racial and ethnic disparities in health care, managers, policy makers, and researchers need valid and reliable data on the race and ethnicity of individuals and populations. The federal government is one of the most important sources of such data. In this paper we review the strengths and weaknesses of federal data that pertain to racial and ethnic disparities in health care. We describe recent developments that are likely to influence how these data can be used in the future and discuss how local programs could make use of these data. PMID:16899018

Racial disparities in clinic attendance may contribute to racial disparities in plasma human immunodeficiency virus type 1 : HIV-1) RNA levels among HIV-positive patients in care. Data from 946 African American and 535 Caucasian patients receiving HIV care at the University of North Carolina Center for AIDS Research HIV clinic between January 1, 1999, and August 1, 2012, were used to estimate the association between African American race and HIV virological suppression (i.e., undetectable HIV-1 RNA) when racial disparities in clinic attendance were lessened. Clinic attendance was measured as the proportion of scheduled clinic appointments attended (i.e., visit adherence) or the proportion of six 4-month intervals with at least 1 attended scheduled clinic appointment (i.e., visit constancy). In analyses accounting for patient characteristics, the risk ratio for achieving suppression when comparing African Americans with Caucasians was 0.91 (95% confidence interval: 0.85, 0.98). Lessening disparities in adherence or constancy lowered disparities in virological suppression by up to 44.4% and 11.1%, respectively. Interventions that lessen disparities in adherence may be more effective in eliminating disparities in suppression than interventions that lessen disparities in constancy. Given that gaps in care were limited to be no more than 2 years for both attendance measures, the impact of lessening disparities in adherence may be overstated. © The Author 2014.

To overcome cardiovascular disease (CVD) disparities impacting high-risk populations, it is critical to train researchers and leaders in conducting community-engaged CVD disparities research. The authors summarize the key elements, implementation, and preliminary outcomes of the CVD Disparities Fellowship and Summer Internship Programs at the Johns Hopkins University Schools of Medicine, Nursing, and Bloomberg School of Public Health. In 2010, program faculty and coordinators established a trans-disciplinary CVD disparities training and career development fellowship program for scientific investigators who desire to conduct community-engaged clinical and translational disparities research. The program was developed to enhance mentorship support and research training for faculty, post-doctoral fellows, and pre-doctoral students interested in conducting CVD disparities research. A CVD Disparities Summer Internship Program for undergraduate and pre-professional students was also created to provide a broad experience in public health and health disparities in Baltimore, Maryland, with a focus on CVD. Since 2010, 39 pre-doctoral, post-doctoral, and faculty fellows have completed the program. Participating fellows have published disparities-related research and given presentations both nationally and internationally. Five research grant awards have been received by faculty fellows. Eight undergraduates, 1 post-baccalaureate, and 2 medical professional students representing seven universities have participated in the summer undergraduate internship. Over half of the undergraduate students are applying to or have been accepted into medical or graduate school. The tailored CVD health disparities training curriculum has been successful at equipping varying levels of trainees (from undergraduate students to faculty) with clinical research and public health expertise to conducting community-engaged CVD disparities research.

Road-traffic injuries: confronting disparities to address a global-health problem.

Ameratunga, Shanthi; Hijar, Martha; Norton, Robyn

2006-05-06

Evidence suggests that the present and projected global burden of road-traffic injuries is disproportionately borne by countries that can least afford to meet the health service, economic, and societal challenges posed. Although the evidence base on which these estimates are made remains somewhat precarious in view of the limited data systems in most low-income and middle-income countries (as per the classification on the World Bank website), these projections highlight the essential need to address road-traffic injuries as a public-health priority. Most well-evaluated effective interventions do not directly focus on efforts to protect vulnerable road users, such as motorcyclists and pedestrians. Yet, these groups comprise the majority of road-traffic victims in low-income and middle-income countries, and consequently, the majority of the road-traffic victims globally. Appropriately responding to these disparities in available evidence and prevention efforts is necessary if we are to comprehensively address this global-health dilemma.

Racial-ethnic disparities in acute stroke care can contribute to inequality in stroke outcomes. We examined race-ethnic disparities in acute stroke performance metrics in a voluntary stroke registry among Florida and Puerto Rico Get With the Guidelines-Stroke hospitals. Seventy-five sites in the Florida Puerto Rico Stroke Registry (66 Florida and 9 Puerto Rico) recorded 58 864 ischemic stroke cases (2010-2014). Logistic regression models examined racial-ethnic differences in acute stroke performance measures and defect-free care (intravenous tissue plasminogen activator treatment, in-hospital antithrombotic therapy, deep vein thrombosis prophylaxis, discharge antithrombotic therapy, appropriate anticoagulation therapy, statin use, smoking cessation counseling) and temporal trends. Among ischemic stroke cases, 63% were non-Hispanic white (NHW), 18% were non-Hispanic black (NHB), 14% were Hispanic living in Florida, and 6% were Hispanic living in Puerto Rico. NHW patients were the oldest, followed by Hispanics, and NHBs. Defect-free care was greatest among NHBs (81%), followed by NHWs (79%) and Florida Hispanics (79%), then Puerto Rico Hispanics (57%) ( P <0.0001). Puerto Rico Hispanics were less likely than Florida whites to meet any stroke care performance metric other than anticoagulation. Defect-free care improved for all groups during 2010-2014, but the disparity in Puerto Rico persisted (2010: NHWs=63%, NHBs=65%, Florida Hispanics=59%, Puerto Rico Hispanics=31%; 2014: NHWs=93%, NHBs=94%, Florida Hispanics=94%, Puerto Rico Hispanics=63%). Racial-ethnic/geographic disparities were observed for acute stroke care performance metrics. Adoption of a quality improvement program improved stroke care from 2010 to 2014 in Puerto Rico and all Florida racial-ethnic groups. However, stroke care quality delivered in Puerto Rico is lower than in Florida. Sustained support of evidence-based acute stroke quality improvement programs is required to improve stroke care and

Outcomes and disparities in liver transplantation will be improved by redistricting-cons.

PubMed

Goldberg, David Seth; Karp, Seth

2017-04-01

Over the last 2 years, the liver transplant community has been debating a proposal to redraw the maps of organ distribution. The basis for these proposed changes is reported disparities in severity of illness at transplantation across the USA - however, this is based on the allocation model for end-stage liver disease score. In this review, we provide a critical overview of the redistribution proposal, its flaws and how it may worsen outcomes and exacerbate disparities in liver transplantation. The main findings we highlight are data questioning the disparity metric used to justify the redistribution. We also review data published in recent articles and presented at public forums questioning whether there truly are disparities in access to transplant care among the broader population with liver disease, and whether disparities even getting to the waitlist are important and not to be ignored. This review article highlights major methodological and policy flaws with the current redistribution proposal. We demonstrate how the waitlist disparities that the proposal is intended to fix are not as they seem. Furthermore, if this proposal is passed, outcomes of liver transplantation nationally may worsen, and disparities for those with limited access to healthcare will worsen.

Objectives. We investigated the role of socioeconomic factors in Black–White disparities in preterm birth (PTB). Methods. We used the population-based California Maternal and Infant Health Assessment survey and birth certificate data on 10 400 US-born Black and White California residents who gave birth during 2003 to 2010 to examine rates and relative likelihoods of PTB among Black versus White women, with adjustment for multiple socioeconomic factors and covariables. Results. Greater socioeconomic advantage was generally associated with lower PTB rates among White but not Black women. There were no significant Black–White disparities within the most socioeconomically disadvantaged subgroups; Black–White disparities were seen only within more advantaged subgroups. Conclusions. Socioeconomic factors play an important but complex role in PTB disparities. The absence of Black–White disparities in PTB within certain socioeconomic subgroups, alongside substantial disparities within others, suggests that social factors moderate the disparity. Further research should explore social factors suggested by the literature—including life course socioeconomic experiences and racism-related stress, and the biological pathways through which they operate—as potential contributors to PTB among Black and White women with different levels of social advantage.

Decrements in sleep health, including insufficient sleep duration, irregular timing of sleep, poor sleep quality, and sleep/circadian disorders are wide-spread in modern society and are associated with an array of disease risks and outcomes, including those contributing to health disparities (e.g. cardiovascular disease, obesity and diabetes, psychiatric illness and cancer). Recent findings have uncovered racial/ethnic and socioeconomic position differences in sleep health, however the contribution of sleep deficiency to health disparities remains largely unexplored, and understanding the underlying causes of disparities in sleep health is only beginning to emerge. In 2011, the National Heart Lung and Blood Institute convened a workshop, bringing together sleep and health disparities investigators, to identify research gaps and opportunities to advance sleep and health disparities science. This article provides a brief background and rationale for the workshop, and disseminates the research recommendations and priorities resulting from the working group discussions. PMID:26431756

Oral health is essential to the general health and well-being of individuals and the population. Yet significant oral health disparities persist in the U.S. population because of a web of influences that include complex cultural and social processes that affect both oral health and access to effective dental health care. This paper introduces an organizing framework for addressing oral health disparities. We present and discuss how the multiple influences on oral health and oral health disparities operate using this framework. Interventions targeted at different causal pathways bring new directions and implications for research and policy in reducing oral health disparities. PMID:16934121

Health disparities in chronic diseases: where the money is.

Crook, Errol D; Peters, Mosha

2008-04-01

Chronic diseases account for three-quarters of the U.S. health care expenditures and a majority of early deaths and lost of productive years of life. Health disparities exist among the common chronic diseases, such as hypertension, diabetes mellitus, HIV/AIDS, cancer, cardiovascular disease, and obesity, with ethnic minorities and the poor having higher incidence or worse outcomes. Strategies to eliminate these disparities in chronic diseases need to be multidisciplinary and focus on increasing access to all aspects of health care, including prevention. This article discusses the impact of health disparities on chronic diseases and offers some factors to consider for solutions to the problem.

2008-01-01

Context Racial and ethnic disparities in health care in the United States have been well documented, with research largely focusing on describing the problem rather than identifying the best practices or proven strategies to address it. Methods In 2006, the Disparities Solutions Center convened a one-and-a-half-day Strategy Forum composed of twenty experts from the fields of racial/ethnic disparities in health care, quality improvement, implementation research, and organizational excellence, with the goal of deciding on innovative action items and adoption strategies to address disparities. The forum used the Results Based Facilitation model, and several key recommendations emerged. Findings The forum's participants concluded that to identify and effectively address racial/ethnic disparities in health care, health care organizations should: (1) collect race and ethnicity data on patients or enrollees in a routine and standardized fashion; (2) implement tools to measure and monitor for disparities in care; (3) develop quality improvement strategies to address disparities; (4) secure the support of leadership; (5) use incentives to address disparities; and (6) create a messaging and communication strategy for these efforts. This article also discusses these recommendations in the context of both current efforts to address racial and ethnic disparities in health care and barriers to progress. Conclusions The Strategy Forum's participants concluded that health care organizations needed a multifaceted plan of action to address racial and ethnic disparities in health care. Although the ideas offered are not necessarily new, the discussion of their practical development and implementation should make them more useful. PMID:18522613

Herbivorous dinosaur jaw disparity and its relationship to extrinsic evolutionary drivers.

PubMed

MacLaren, Jamie A; Anderson, Philip S L; Barrett, Paul M; Rayfield, Emily J

2017-02-01

Morphological responses of nonmammalian herbivores to external ecological drivers have not been quantified over extended timescales. Herbivorous nonavian dinosaurs are an ideal group to test for such responses, because they dominated terrestrial ecosystems for more than 155 Myr and included the largest herbivores that ever existed. The radiation of dinosaurs was punctuated by several ecologically important events, including extinctions at the Triassic/Jurassic (Tr/J) and Jurassic/Cretaceous (J/K) boundaries, the decline of cycadophytes, and the origin of angiosperms, all of which may have had profound consequences for herbivore communities. Here we present the first analysis of morphological and biomechanical disparity for sauropodomorph and ornithischian dinosaurs in order to investigate patterns of jaw shape and function through time. We find that morphological and biomechanical mandibular disparity are decoupled: mandibular shape disparity follows taxonomic diversity, with a steady increase through the Mesozoic. By contrast, biomechanical disparity builds to a peak in the Late Jurassic that corresponds to increased functional variation among sauropods. The reduction in biomechanical disparity following this peak coincides with the J/K extinction, the associated loss of sauropod and stegosaur diversity, and the decline of cycadophytes. We find no specific correspondence between biomechanical disparity and the proliferation of angiosperms. Continual ecological and functional replacement of pre-existing taxa accounts for disparity patterns through much of the Cretaceous, with the exception of several unique groups, such as psittacosaurids that are never replaced in their biomechanical or morphological profiles.

2011-01-01

Background Cancer incidence and mortality rates have decreased over the last few decades, yet not all groups have benefited equally from these successes. This has resulted in increased disparities in cancer burden among various population groups. Objective This study examined trends in absolute and relative disparities in overall cancer incidence and mortality rates between African American and white residents of Wisconsin during 1995 to 2006. Methods Cancer incidence data were obtained from the Wisconsin Cancer Reporting System. Mortality data were accessed from the National Center for Health Statistics’ public use mortality file. Trends in incidence and mortality rates during 1995–2006 for African Americans and whites were calculated and changes in relative disparity were measured using rate ratios. Results With few exceptions, African American incidence and mortality rates were higher than white rates in every year of the period 1995–2006. Although cancer mortality and incidence declined for both groups over the period, relative racial disparities in rates persisted over the period and account for about a third of African American cancer deaths. Conclusions Elimination of cancer health disparities will require further research into the many contributing factors, as well as into effective interventions to address them. In Wisconsin, policy makers, health administrators, and healthcare providers need to balance resources carefully and set appropriate priorities to target racial inequities in cancer burden.

Malhotra, Chetna; Do, Young Kyung

2013-03-01

To assess the magnitude of socio-economic disparities in health system responsiveness in India after correcting for potential reporting heterogeneity by socio-economic characteristics (education and wealth). Data from Wave 1 of the Study on Global Ageing and Adult Health (2007-2008) involving six Indian states were used. Seven health system responsiveness domains were considered for a respondent's last visit to an outpatient service in 12 months: prompt attention, dignity, clarity of information, autonomy, confidentiality, choice and quality of basic amenities. Hierarchical ordered probit models (correcting for reporting heterogeneity through anchoring vignettes) were used to assess the association of socio-economic characteristics with the seven responsiveness domains, controlling for age, gender and area of residence. Stratified analysis was also conducted among users of public and private health facilities. Our statistical models accounting for reporting heterogeneity revealed socio-economic disparities in all health system responsiveness domains. Estimates suggested that individuals from the lowest wealth group, for example, were less likely than individuals from the highest wealth group to report 'very good' on the dignity domain by 8% points (10% vs 18%). Stratified analysis showed that such disparities existed among users of both public and private health facilities. Socio-economic disparities exist in health system responsiveness in India, irrespective of the type of health facility used. Policy efforts to monitor and improve these disparities are required at the health system level.

Disparities in infant mortality and effective, equitable care: are infants suffering from benign neglect?

PubMed

Rowley, Diane L; Hogan, Vijaya

2012-04-01

Quality care for infant mortality disparity elimination requires services that improve health status at both the individual and the population level. We examine disparity reduction due to effective care and ask the following question: Has clinical care ameliorated factors that make some populations more likely to have higher rates of infant mortality compared with other populations? Disparities in postneonatal mortality due to birth defects have emerged for non-Hispanic black and Hispanic infants. Surfactant and antenatal steroid therapy have been accompanied by growing disparities in respiratory distress syndrome mortality for black infants. Progesterone therapy has not reduced early preterm birth, the major contributor to mortality disparities among non-Hispanic black and Puerto Rican infants. The Back to Sleep campaign has minimally reduced SIDS disparities among American Indian/Alaska Native infants, but it has not reduced disparities among non-Hispanic black infants. In general, clinical care is not equitable and contributes to increasing disparities.

Disparities in neighborhood food access are well documented, but little research exists on how shocks influence such disparities. We examined neighborhood food access in New Orleans at 3 time points: before Hurricane Katrina (2004–2005), in 2007, and in 2009. We combined existing directories with on-the-ground verification and geographic information system mapping to assess supermarket counts in the entire city. Existing disparities for African American neighborhoods worsened after the storm. Although improvements have been made, by 2009 disparities were no better than prestorm levels. PMID:21233432

Effect of Medicaid Managed Care on racial disparities in health care access.

Cook, Benjamin Lê

2007-02-01

To evaluate the impact of Medicaid Managed Care (MMC) on racial disparities in access to care consistent with the Institute of Medicine (IOM) definition of racial disparity, which excludes differences stemming from health status but includes socioeconomic status (SES)-mediated differences. Secondary data from the Adult Samples of the 1997-2001 National Health Interview Survey, metropolitan statistical area (MSA)-level Medicaid Health Maintenance Organization (MHMO) market share from the 1997 to 2001 InterStudy MSA Trend Dataset, and MSA characteristics from the 1997 to 2001 Area Resource File. I estimate multivariate regression models to compare racial disparities in doctor visits, emergency room (ER) use, and having a usual source of care between enrollees in MMC and Medicaid Fee-for-Service (FFS) plans. To contend with potential selection bias, I use a difference-in-difference analytical strategy and assess the impact of greater MHMO market share at the MSA level on Medicaid enrollees' access measures. To implement the IOM definition of racial disparity, I adjust for health status but not SES factors using a novel method to transform the distribution of health status for minority populations to approximate the white health status distribution. MMC enrollment is associated with lowered disparities in having any doctor visit in the last year for blacks, and in having any usual source of care for both blacks and Hispanics. Increasing Medicaid HMO market share lowered disparities in having any doctor visits in the last year for both blacks and Hispanics. Although disparities in most other measures were not much affected, black-white ER use disparities exist among MMC enrollees and in areas of high MHMO market share. MMC programs' reduction of some disparities suggests that recent shifts in Medicaid policy toward managed care plans have benefited minority enrollees. Future research should investigate whether black-white disparities in ER use within MMC groups

Health disparities and gaps in school readiness.

PubMed

Currie, Janet

2005-01-01

The author documents pervasive racial disparities in the health of American children and analyzes how and how much those disparities contribute to racial gaps in school readiness. She explores a broad sample of health problems common to U.S. children, such as attention deficit hyperactivity disorder, asthma, and lead poisoning, as well as maternal health problems and health-related behaviors that affect children's behavioral and cognitive readiness for school. If a health problem is to affect the readiness gap, it must affect many children, it must be linked to academic performance or behavior problems, and it must show a racial disparity either in its prevalence or in its effects. The author focuses not only on the black-white gap in health status but also on the poor-nonpoor gap because black children tend to be poorer than white children. The health conditions Currie considers seriously impair cognitive skills and behavior in individual children. But most explain little of the overall racial gap in school readiness. Still, the cumulative effect of health differentials summed over all conditions is significant. Currie's rough calculation is that racial differences in health conditions and in maternal health and behaviors together may account for as much as a quarter of the racial gap in school readiness. Currie scrutinizes several policy steps to lessen racial and socioeconomic disparities in children's health and to begin to close the readiness gap. Increasing poor children's eligibility for Medicaid and state child health insurance is unlikely to be effective because most poor children are already eligible for public insurance. The problem is that many are not enrolled. Even increasing enrollment may not work: socioeconomic disparities in health persist in Canada and the United Kingdom despite universal public health insurance. The author finds more promise in strengthening early childhood programs with a built-in health component, like Head Start; family

OBJECTIVE To evaluate the attitudes and perceptions of primary care providers (PCPs) regarding the presence and underlying sources of racial/ethnic and socioeconomic disparities in hypertension control. METHODS We conducted a survey of 115 PCPs from 2 large academic centers in Colorado. We included physicians, nurse practitioners, and physician assistants. The survey assessed provider recognition and perceived contributors of disparities in hypertension control. RESULTS Respondents were primarily female (66%), non-Hispanic White (84%), and physicians (80%). Among respondents, 67% and 73% supported the collection of data on the patients’ race/ethnicity and socioeconomic status (SES), respectively. Eighty-six percent and 89% agreed that disparities in race/ethnicity and SES existed in hypertension care within the US health system. However, only 33% and 44% thought racial/ethnic and socioeconomic disparities existed in the care of their own patients. Providers were more likely to perceive patient factors rather than provider or health system factors as mediators of disparities. However, most supported interventions such as improving provider communication skills (87%) and cultural competency training (89%) to reduce disparities in hypertension control. CONCLUSIONS Most providers acknowledged that racial/ethnic and socioeconomic disparities in hypertension control exist in the US health system, but only a minority reported disparities in care among patients they personally treat. Our study highlights the need for testing an intervention aimed at increasing provider awareness of disparities within the local health setting to improve hypertension control for minority patients.

This study compared trends in racial-ethnic disparities in mental health care access among whites, blacks, Hispanics, and Asians by using the Institute of Medicine definition of disparities as all differences except those due to clinical appropriateness, clinical need, and patient preferences. Racial-ethnic disparities in mental health care access were examined by using data from a nationally representative sample of 214,597 adults from the 2004-2012 Medical Expenditure Panel Surveys. The main outcome measures included three mental health care access measures (use of any mental health care, any outpatient care, and any psychotropic medication in the past year). Significant disparities were found in 2004-2005 and in 2011-2012 for all three racial-ethnic minority groups compared with whites in all three measures of access. Between 2004 and 2012, black-white disparities in any mental health care and any psychotropic medication use increased, respectively, from 8.2% to 10.8% and from 7.6% to 10.0%. Similarly, Hispanic-white disparities in any mental health care and any psychotropic medication use increased, respectively, from 8.4% to 10.9% and 7.3% to 10.3%. No reductions in racial-ethnic disparities in access to mental health care were identified between 2004 and 2012. For blacks and Hispanics, disparities were exacerbated over this period. Clinical interventions that improve identification of symptoms of mental illness, expansion of health insurance, and other policy interventions that remove financial barriers to access may help to reduce these disparities.

Despite yearly advances in life-saving and preventive medicine, as well as strategic approaches by governmental and social agencies and groups, significant disparities remain in health, health quality, and access to health care within the United States. The determinants of these disparities include baseline health status, race and ethnicity, culture, gender identity and expression, socioeconomic status, region or geography, sexual orientation, and age. In order to renew the commitment of the medical community to address health disparities, particularly at the medical school level, we must remind ourselves of the roles of doctors and medical schools as the gatekeepers and the value setters for medicine. Within those roles are responsibilities toward the social mission of working to eliminate health disparities. This effort will require partnerships with communities as well as with academic centers to actively develop and to implement diversity and inclusion strategies. Besides improving the diversity of trainees in the pipeline, access to health care can be improved, and awareness can be raised regarding population-based health inequalities. PMID:23659676

Getting to equal: strategies to understand and eliminate general and orthopaedic healthcare disparities.

The 2001 Institute of Medicine report entitled Unequal Treatment: Confronting Racial and Ethnic Disparities in Health Care pointed out extensive healthcare disparities in the United States even when controlling for disease severity, socioeconomic status, education, and access. The literature identifies several groups of Americans who receive disparate healthcare: ethnic minorities, women, children, the elderly, the handicapped, the poor, prisoners, lesbians, gays, and the transgender population. Disparate healthcare represents an enormous current challenge with substantial moral, ethical, political, public health, public policy, and economic implications, all of which are likely to worsen over the next several decades without immediate and comprehensive action. A review of recent literature reveals over 100 general and specific suggestions and solutions to eliminate healthcare disparities. While healthcare disparities have roots in multiple sources, racial stereotypes and biases remain a major contributing factor and are prototypical of biases based on age, physical handicap, socioeconomic status, religion, sexual orientation or other differences. Given that such disparities have a strong basis in racial biases, and that the principles of racism are similar to those of other "isms", we summarize the current state of healthcare disparities, the goals of their eradication, and the various potential solutions from a conceptual model of racism affecting patients (internalized racism), caregivers (personally mediated racism), and society (institutionalized racism).

Context A disaster is indiscriminate in whom it affects. Limited research has shown that the poor and medically underserved, especially in rural areas, bear an inequitable amount of the burden. Objective To review the literature on the combined effects of a disaster and living in an area with existing health or health care disparities on a community’s health, access to health resources, and quality of life. Methods We performed a systematic literature review using the following search terms: disaster, health disparities, health care disparities, medically underserved, and rural. Our inclusion criteria were peer-reviewed, US studies that discussed the delayed or persistent health effects of disasters in medically underserved areas. Results There has been extensive research published on disasters, health disparities, health care disparities, and medically underserved populations individually, but not collectively. Conclusions The current literature does not capture the strain of health and health care disparities before and after a disaster in medically underserved communities. Future disaster studies and policies should account for differences in health profiles and access to care before and after a disaster. PMID:20389193

Stereoacuity versus fixation disparity as indicators for vergence accuracy under prismatic stress.

Fixation disparity has been widely used as an indicator for vergence accuracy under prismatic stress. However, the targets used for measuring fixation disparity contain artificial features in that the fusional contours are thinned out. We considered that stereoacuity might be a preferable indicator of vergence accuracy, as stereo targets represent natural viewing conditions. We measured fixation disparity with a computer adaptation of Ogle's test and stereoacuity with the automatic Freiburg Stereoacuity Test. Eight subjects were examined under increasing base-in and base-out prisms. The response of fixation disparity to prismatic stress revealed the curve types described by Ogle and Crone. All eight subjects reached a stereoscopic threshold below 10 arcsec. In seven subjects the stereoscopic threshold increased before double vision occurred. Our data suggest that stereoacuity is suitable to assess the range of binocular vision under prismatic stress. As stereoacuity bears the advantage over fixation disparity in that it can be measured without introducing artificial viewing conditions, we suggest exploring whether stereoacuity under prismatic stress would be more meaningful in the work-up of asthenopic patients than is fixation disparity.

Racial Disparities in Access to Care Under Conditions of Universal Coverage.

Racial disparities in access to regular health care have been reported in the U.S., but little is known about the extent of disparities in societies with universal coverage. To investigate the extent of racial disparities in access to care under conditions of universal coverage by observing the association between race and regular access to a doctor in Canada. Racial disparities in access to a regular doctor were calculated using the largest available source of nationally representative data in Canada--the Canadian Community Health Survey. Surveys from 2000-2010 were analyzed in 2014. Multinomial regression analyses predicted odds of having a regular doctor for each racial group compared to whites. Analyses were stratified by immigrant status--Canadian-born versus shorter-term immigrant versus longer-term immigrants--and controlled for sociodemographics and self-rated health. Racial disparities in Canada, a country with universal coverage, were far more muted than those previously reported in the U.S. Only among longer-term Latin American immigrants (OR=1.90, 95% CI=1.45, 2.08) and Canadian-born Aboriginals (OR=1.34, 95% CI=1.22, 1.47) were significant disparities noted. Among shorter-term immigrants, all Asians were more likely than whites, and among longer-term immigrants, South Asians were more like than whites, to have a regular doctor. Universal coverage may have a major impact on reducing racial disparities in access to health care, although among some subgroups, other factors may also play a role above and beyond health insurance.

We examine disparities in birth weight and gestational age by ethnic ancestry in 2000-2011 in eight South American countries. The sample included 60,480 singleton live births. Regression models were estimated to evaluate differences in birth outcomes by ethnic ancestry controlling for time trends. Significant disparities were found in seven countries. In four countries-Brazil, Ecuador, Uruguay, and Venezuela-we found significant disparities in both low birth weight and preterm birth. Disparities in preterm birth alone were observed in Argentina, Bolivia, and Colombia. Several differences in continuous birth weight, gestational age, and fetal growth rate were also observed. There were no systematic patterns of disparities between the evaluated ethnic ancestry groups across the study countries, in that no racial/ethnic group consistently had the best or worst outcomes in all countries. Racial/ethnic disparities in infant health are common in several South American countries. Differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms. Researchers and policymakers should acknowledge these disparities and develop research and policy programs to effectively target them.

Genetic Contributions to Disparities in Preterm Birth

Ethnic disparity in preterm delivery between African Americans and European Americans has existed for decades, and is likely the consequence of multiple factors, including socioeconomic status, access to care, environment, and genetics. This review summarizes existing information on genetic variation and its association with preterm birth in African Americans. Candidate gene-based association studies, in which investigators have evaluated particular genes selected primarily because of their potential roles in the process of normal and pathological parturition, provide evidence that genetic contributions from both mother and fetus account for some of the disparity in preterm births. To date, most attention has been focused on genetic variation in pro- and anti-inflammatory cytokine genes and their respective receptors. These genes, particularly the pro-inflammatory cytokine genes and their receptors, are linked to matrix metabolism since these cytokines increase expression of matrix degrading metalloproteinases. However, the role that genetic variants that are different between populations play in preterm birth cannot yet be quantified. Future studies based on genome wide association or admixture mapping may reveal other genes that contribute to disparity in prematurity. PMID:18787421

The Kidney Allocation System fundamentally altered kidney allocation, causing a substantial increase in regional and national sharing that we hypothesized might impact geographic disparities. We measured geographic disparity in deceased donor kidney transplant (DDKT) rate under KAS (6/1/2015-12/1/2016), and compared that with pre-KAS (6/1/2013-12/3/2014). We modeled DSA-level DDKT rates with multilevel Poisson regression, adjusting for allocation factors under KAS. Using the model we calculated a novel, improved metric of geographic disparity: the median incidence rate ratio (MIRR) of transplant rate, a measure of DSA-level variation that accounts for patient casemix and is robust to outlier values. Under KAS, MIRR was 1.75 1.81 1.86 for adults, meaning that similar candidates across different DSAs have a median 1.81-fold difference in DDKT rate. The impact of geography was greater than the impact of factors emphasized by KAS: having an EPTS score ≤20% was associated with a 1.40-fold increase (IRR =  1.35 1.40 1.45 , P < .01) and a three-year dialysis vintage was associated with a 1.57-fold increase (IRR =  1.56 1.57 1.59 , P < .001) in transplant rate. For pediatric candidates, MIRR was even more pronounced, at 1.66 1.92 2.27 . There was no change in geographic disparities with KAS (P = .3). Despite extensive changes to kidney allocation under KAS, geography remains a primary determinant of access to DDKT. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

Racial Disparities in Hepatitis C Treatment Eligibility.

Hepatitis C (HCV) is more prevalent in African Americans than in any other racial group in the United States. However, African Americans are more likely to be deemed ineligible for HCV treatment than non-African Americans. There has been limited research into the origins of racial disparities in HCV treatment eligibility. The purpose of this study was to compare medical and non-medical characteristics commonly assessed in clinical practice that could potentially contribute to HCV treatment ineligibility disparities between African American and non-African American patients. Patients with confirmed HCV RNA considering treatment (n = 309) were recruited from university-affiliated and VA liver and infectious disease clinics. African Americans and non-African Americans did not differ in prevalence of lifetime and current psychiatric disorders and risky behaviors, and HCV knowledge. HCV clinical characteristics were similar between both groups in terms of HCV exposure history, number of months aware of HCV diagnosis, stage of fibrosis, and HCV virologic levels. African Americans did have higher proportions of diabetes, renal disease, and bleeding ulcer. No clinical evidence was found to indicate that African Americans should be more often deemed ineligible for HCV treatment than other racial groups. Diabetes and renal disease do not fully explain the HCV treatment ineligibility racial disparity, because HCV patients with these conditions are priority patients for HCV treatment because of their greater risk for cirrhosis, steatosis, and hepatocellular carcinoma. The findings suggest that an underlying contributor to the HCV treatment eligibility disparity disfavoring African Americans could be racial discrimination.

The authors consider the challenges to quantifying both the business case and the social case for addressing disparities, which is central to achieving equity in the U.S. health care system. They describe the practical and methodological challenges faced by health plans exploring the business and social cases for undertaking disparity-reducing interventions. Despite these challenges, sound business and quality improvement principles can guide health care organizations seeking to reduce disparities. Place-based interventions may help focus resources and engage health care and community partners who can share in the costs of-and gains from-such efforts.

In this paper, variable disparity-motion estimation (VDME) based 3-view video coding is proposed. In the encoding, key-frame coding (KFC) based motion estimation and variable disparity estimation (VDE) for effectively fast three-view video encoding are processed. These proposed algorithms enhance the performance of 3-D video encoding/decoding system in terms of accuracy of disparity estimation and computational overhead. From some experiments, stereo sequences of 'Pot Plant' and 'IVO', it is shown that the proposed algorithm's PSNRs is 37.66 and 40.55 dB, and the processing time is 0.139 and 0.124 sec/frame, respectively.

Racial/ethnic minorities in the United States are more likely than Whites to have severe and persistent mental disorders and less likely to access mental health care. This comprehensive review evaluates studies of mental health and mental health care disparities funded by the National Institute of Mental Health (NIMH) to provide a benchmark for the 2015 NIMH revised strategic plan. A total of 615 articles were categorized into five pathways underlying mental health care and three pathways underlying mental health disparities. Identified studies demonstrate that socioeconomic mechanisms and demographic moderators of disparities in mental health status and treatment are well described, as are treatment options that support diverse patient needs. In contrast, there is a need for studies that focus on community- and policy-level predictors of mental health care disparities, link discrimination- and trauma-induced neurobiological pathways to disparities in mental illness, assess the cost effectiveness of disparities reduction programs, and scale up culturally adapted interventions.

The first 50Myr of dinosaur evolution: macroevolutionary pattern and morphological disparity.

Brusatte, Stephen L; Benton, Michael J; Ruta, Marcello; Lloyd, Graeme T

2008-12-23

The evolutionary radiation of dinosaurs in the Late Triassic and Early Jurassic was a pivotal event in the Earth's history but is poorly understood, as previous studies have focused on vague driving mechanisms and have not untangled different macroevolutionary components (origination, diversity, abundance and disparity). We calculate the morphological disparity (morphospace occupation) of dinosaurs throughout the Late Triassic and Early Jurassic and present new measures of taxonomic diversity. Crurotarsan archosaurs, the primary dinosaur 'competitors', were significantly more disparate than dinosaurs throughout the Triassic, but underwent a devastating extinction at the Triassic-Jurassic boundary. However, dinosaur disparity showed only a slight non-significant increase after this event, arguing against the hypothesis of ecological release-driven morphospace expansion in the Early Jurassic. Instead, the main jump in dinosaur disparity occurred between the Carnian and Norian stages of the Triassic. Conversely, dinosaur diversity shows a steady increase over this time, and measures of diversification and faunal abundance indicate that the Early Jurassic was a key episode in dinosaur evolution. Thus, different aspects of the dinosaur radiation (diversity, disparity and abundance) were decoupled, and the overall macroevolutionary pattern of the first 50Myr of dinosaur evolution is more complex than often considered.

To examine whether having a primary care physician (PCP) is associated with reduced ethnic disparities for colorectal cancer (CRC) screening and whether clustering of minorities within PCPs contributes to the disparities. Retrospective cohort study of Medicare beneficiaries age 66-75 in 2009 in Texas. The percentage of beneficiaries up to date in CRC screening in 2009 was stratified by race/ethnicity. Multilevel models were used to study the effect of having a PCP and PCP characteristics on the racial and ethnic disparities on CRC screening. Medicare data from 2000 to 2009 were used to assess prior CRC screening. Odds of undergoing CRC screening were more than twice as high in patients with a PCP (OR = 2.05, 95 percent CI 2.03-2.07). After accounting for clustering and PCP characteristics, the black-white disparity in CRC screening rates almost disappears and the Hispanic-white disparity decreases substantially. Ethnic disparities in CRC screening in the elderly are mostly explained by decreased access to PCPs and by clustering of minorities within PCPs less likely to screen any of their patients. © Health Research and Educational Trust.

Translating Research into Policy: Reducing Breast Cancer Disparities in Illinois

Cancer.gov

Dr. Carol Ferrans is internationally recognized for her work in disparities in health care and quality of life outcomes. She has a distinguished record of research that includes major grants funded by three institutes of the National Institutes of Health (National Cancer Institute, National Institute for Minority Health and Health Disparities, and National Institute for Nursing Research).    Dr. Ferrans’ work has been instrumental in reducing the disparity in breast cancer mortality Chicago, which at its peak was among the worst in the nation.  Efforts led by Dr. Ferrans and colleagues led directly to statewide legislation, to address the multifaceted causes of black/white disparity in deaths from breast cancer.  She was one of the founders of the Metropolitan Chicago Breast Cancer Task Force (MCBCTF), leading the team focusing on barriers to mammography screening, to identify reasons for the growing disparity in breast cancer mortality. Their findings (citing Ferrans’ research and others) and recommendations for action were translated directly into the Illinois Reducing Breast Cancer Disparities Act and two additional laws strengthening the Act.  These laws and other statewide efforts have improved access to screening and quality of mammography throughout the Illinois. In addition, Dr. Ferrans and her team identified cultural beliefs contributing to later stage diagnosis of breast cancer in African American and Latino women in Chicago, and most importantly, showed that these beliefs can be changed.  They reached more than 8,000 African American women in Chicago with a short film on DVD, which was effective in changing beliefs and promoting screening.  Her team’s published findings were cited by the American Cancer Society in their guidelines for breast cancer screening.  The Chicago black/white disparity in breast cancer deaths has decreased by 35% since the MCBCTF first released its report, according to data from the Illinois Department of Public

Introduction: In 2005, the National Cancer Institute funded the Community Networks Program (CNP), which aimed to reduce cancer health disparities in minority racial/ethnic and underserved groups through community-based participatory research, education, and training. The purpose of this study was to describe the CNP model and their tobacco-related work in community-based research, education, and training using a tobacco disparities research framework. Methods: We conducted a comprehensive review of the CNP tobacco-related activities including publications, published abstracts, research activities, trainee pilot studies, policy-related activities, educational outreach, and reports produced from 2005–2009. Two authors categorized the tobacco-related activities and publications within the framework. Results: Although there was no mandate to address tobacco, the CNPs produced 103 tobacco-related peer-reviewed publications, which reflects the largest proportion (12%) of all CNP cancer-related publications. Selected publications and research activities were most numerous under the framework areas “Psychosocial Research,” “Surveillance,” “Epidemiology,” and “Treatment of Nicotine Addiction.” Thirteen CNPs participated in tobacco control policymaking in mainstream efforts that affected their local community and populations, and 24 CNPs conducted 1147 tobacco-related educational outreach activities. CNP activities that aimed to build research and infrastructure capacity included nine tobacco-related pilot projects representing 16% of all CNP cancer-related pilot projects, and 17 publications acknowledging leveraged partnerships with other organizations, a strategy encouraged by the CNP. Conclusions: The CNP is a promising academic-community model for working to eliminate tobacco-related health disparities. Future efforts may address scientific gaps, consider collaboration across groups, assess the extent of operationalizing community-based participatory

Background Large socio-economic disparities exist in US dietary habits and cardiovascular disease (CVD) mortality. While economic incentives have demonstrated success in improving dietary choices, the quantitative impact of different dietary policies on CVD disparities is not well established. We aimed to quantify and compare the potential effects on total CVD mortality and disparities of specific dietary policies to increase fruit and vegetable (F&V) consumption and reduce sugar-sweetened beverage (SSB) consumption in the US. Methods and findings Using the US IMPACT Food Policy Model and probabilistic sensitivity analyses, we estimated and compared the reductions in CVD mortality and socio-economic disparities in the US population potentially achievable from 2015 to 2030 with specific dietary policy scenarios: (a) a national mass media campaign (MMC) aimed to increase consumption of F&Vs and reduce consumption of SSBs, (b) a national fiscal policy to tax SSBs to increase prices by 10%, (c) a national fiscal policy to subsidise F&Vs to reduce prices by 10%, and (d) a targeted policy to subsidise F&Vs to reduce prices by 30% among Supplemental Nutrition Assistance Program (SNAP) participants only. We also evaluated a combined policy approach, combining all of the above policies. Data sources included the Surveillance, Epidemiology, and End Results Program, National Vital Statistics System, National Health and Nutrition Examination Survey, and published meta-analyses. Among the individual policy scenarios, a national 10% F&V subsidy was projected to be most beneficial, potentially resulting in approximately 150,500 (95% uncertainty interval [UI] 141,400–158,500) CVD deaths prevented or postponed (DPPs) by 2030 in the US. This far exceeds the approximately 35,100 (95% UI 31,700–37,500) DPPs potentially attributable to a 30% F&V subsidy targeting SNAP participants, the approximately 25,800 (95% UI 24,300–28,500) DPPs for a 1-y MMC, or the approximately 31,000 (95

The goal of this analysis is to assess the effectiveness of a summer program designed to introduce high school students of color to health disparities research. A total of 73 students (69.9% Black, 68.5% female and 80.6% either junior/senior) participated in the 4-week Health Disparities Summer Internship Program (HDSIP) during the years 2012-2015. Students attended lectures covering topics such as health disparities, community-based participatory research (CBPR), immigrant health, and policy and advocacy. While working with community-based organizations, students gained hands-on experience related to issues discussed in class. Students completed research projects and provided suggestions for health policy change. Pre/post surveys were completed to evaluate the program. After participating in the HDSIP, students demonstrated heightened awareness of the social determinants of health, especially in regards to racial discrimination (p = .023); borderline statistically significant increases were shown for income (p = .082), community safety (p = .058), and healthcare access (p = .076). Most students (82.1%) planned to advocate for changes in their community; an increase from the initial 65.2% (p = .052). About nine out of ten students (89.6%) reported being satisfied with the summer program; the majority reported improvement in analytical skills, CBPR methods, and oral/communication skills. Increasing diversity in the health workforce has widely been proposed as a means of addressing health disparities. Introducing minority students to health professions can serve as a catalyst for lasting changes in health outcomes. The HDSIP has increased students' awareness of social determinants of health and has fostered their interest in improving the health of minority populations.

Reducing Racial Health Care Disparities: A Social Psychological Analysis.

Large health disparities persist between Black and White Americans. The social psychology of intergroup relations suggests some solutions to health care disparities due to racial bias. Three paths can lead from racial bias to poorer health among Black Americans. First is the already well-documented physical and psychological toll of being a target of persistent discrimination. Second, implicit bias can affect physicians' perceptions and decisions, creating racial disparities in medical treatments, although evidence is mixed. The third path describes a less direct route: Physicians' implicit racial bias negatively affects communication and the patient-provider relationship, resulting in racial disparities in the outcomes of medical interactions. Strong evidence shows that physician implicit bias negatively affects Black patients' reactions to medical interactions, and there is good circumstantial evidence that these reactions affect health outcomes of the interactions. Solutions focused on the physician, the patient, and the health care delivery system; all agree that trying to ignore patients' race or to change physicians' implicit racial attitudes will not be effective and may actually be counterproductive. Instead, solutions can minimize the impact of racial bias on medical decisions and on patient-provider relationships.

Species diversity vs. morphological disparity in the light of evolutionary developmental biology

PubMed Central

Minelli, Alessandro

2016-01-01

Background Two indicators of a clade’s success are its diversity (number of included species) and its disparity (extent of morphospace occupied by its members). Many large genera show high diversity with low disparity, while others such as Euphorbia and Drosophila are highly diverse but also exhibit high disparity. The largest genera are often characterized by key innovations that often, but not necessarily, coincide with their diagnostic apomorphies. In terms of their contribution to speciation, apomorphies are either permissive (e.g. flightlessness) or generative (e.g. nectariferous spurs). Scope Except for Drosophila, virtually no genus among those with the highest diversity or disparity includes species currently studied as model species in developmental genetics or evolutionary developmental biology (evo-devo). An evo-devo approach is, however, potentially important to understand how diversity and disparity could rapidly increase in the largest genera currently accepted by taxonomists. The most promising directions for future research and a set of key questions to be addressed are presented in this review. Conclusions From an evo-devo perspective, the evolution of clades with high diversity and/or disparity can be addressed from three main perspectives: (1) evolvability, in terms of release from previous constraints and of the presence of genetic or developmental conditions favouring multiple parallel occurrences of a given evolutionary transition and its reversal; (2) phenotypic plasticity as a facilitator of speciation; and (3) modularity, heterochrony and a coupling between the complexity of the life cycle and the evolution of diversity and disparity in a clade. This simple preliminary analysis suggests a set of topics that deserve priority for scrutiny, including the possible role of saltational evolution in the origination of high diversity and/or disparity, the predictability of morphological evolution following release from a former constraint, and

Increasing the engagement of racial and ethnic minorities in genomic research may help alleviate health disparities. This paper examines community perceptions of the relationships between race, genes, environment, and health disparities, and it discusses how such perceptions may influence participation in genomic research. We conducted semi-structured interviews with 91 African American, Latino, and white lay community members and community leaders in North Carolina. Using constant comparison methods, we identified, compared, and developed linkages between conceptual categories and respondent groups. Participants described gene-environment interactions as contributing to group differences in health outcomes, expressed the belief that genetic predisposition to disease differs across groups, and said that social conditions trigger group-level genetic differences and create poorer health outcomes among African Americans. Given the regional presence of major research institutions and the relatively high education level of many participants, this sample may not reflect the perspectives of those most disparately affected by health disparities. Members from multiple community sectors share perceptions and may respond to similar approaches when attempts are made to increase participation in genomic research. Researchers may inadvertently fuel the perception that health disparities experienced by minorities are rooted in the shared genomes of a particular group as distinct from those of other groups. The way researchers use race and ethnicity in recruitment, analysis, and communication of research findings inaccurately implies that there are genetic differences between races, when categories of social experience or ancestry may more accurately characterize health differences. Understanding these issues is crucial to designing effective community engagement strategies, recruitment plans, and messages about genomic research, which could ultimately help to lessen health

Health outcome disparities in racial minorities are well documented. However, it is unknown whether such disparities exist among elderly injured patients. We hypothesized that such disparities might be reduced in the elderly owing to insurance coverage under Medicare. We investigated this issue by comparing the trauma outcomes in young and elderly patients in California. A retrospective analysis of the California Office of Statewide Health Planning and Development hospital discharge database was performed for all publicly available years from 1995 to 2008. Trauma admissions were identified by International Classification of Disease, Ninth Revision, primary diagnosis codes from 800 to 959, with certain exclusions. Multivariate analysis examined the adjusted risk of in-hospital mortality in young (<65 y) and elderly (≥65 y) patients, controlling for age, gender, injury severity as measured by the survival risk ratio, Charlson comorbidity index, insurance status, calendar year, and teaching hospital status. A total of 1,577,323 trauma patients were identified. Among the young patients, the adjusted odds ratio of death relative to non-Hispanic whites for blacks, Hispanics, Asians, and Native Americans/others was 1.2, 1.2, 0.90, and 0.78, respectively. The corresponding adjusted odds ratios of death for elderly patients were 0.78, 0.87, 0.92, and 0.61. Young black and Hispanic trauma patients had greater mortality risks relative to non-Hispanic white patients. Interestingly, elderly black and Hispanic patients had lower mortality risks compared with non-Hispanic whites. Copyright © 2013 Elsevier Inc. All rights reserved.

Socioeconomic dynamics of gender disparity in childhood immunization in India, 1992-2006.

Recent evidence indicated that gender disparity in child health is minimal and narrowed over time in India. However, considering the geographical and socio-cultural diversity in India, the gender gap may persist across disaggregated socioeconomic context which may be masked by average level. This study examines the dynamics of gender disparity in childhood immunization across regions, residence, wealth, caste and religion in India during 1992-2006. We used multi-waves of the cross-sectional data of National Family Health Survey conducted in India between 1992-93 and 2005-06. Gender disparity ratio was used to measure the gender gap in childhood immunization across the selected socioeconomic characteristics. Multinomial regression analysis was used to examine the gender gap after accounting for other covariates. Results indicate that, at aggregate level, gender disparity in full immunization is minimal and has stagnated during the study period. However, gender disparity--disfavouring female children--becomes apparent across the regions, poor households, and religion--particularly among Muslims. Adjusted gender disparity ratio indicates that, full immunization is lower among female than male children of the western region, poor household and among Muslims. Between 1992-93 and 2005-06, the disparity in full immunization had narrowed in the northern region whereas it had, astonishingly, increased in some of the western and southern states of the country. Our findings emphasize the need to integrate gender issues in the ongoing immunization programme in India, with particular attention to urban areas, developed states, and to the Muslim community.

The numbers and proportions of racial and ethnic minorities have increased dramatically in US nursing homes in recent years. Concerns exist about whether nursing homes can serve appropriately the clinical and psychosocial needs of patients with increasingly diverse ethnic and cultural backgrounds. This study determined racial and ethnic disparities in social engagement among nursing home long-term residents. We analyzed the 2008 national Minimum Data Set supplemented with the Online Survey, Certification, and Reporting File and the Area Resource File. We estimated multivariable logistic regressions to determine disparities and how disparities were explained by individual, facility, and geographic factors. Stratified analyses further determined persistent disparities within patient and facility subgroups. Compared with white residents (n = 690,228), black (n = 123,116), Hispanic (n = 37,099), and other (n = 17,568) residents showed lower social engagement, with overall scores (mean ± SD) being 2.5 ± 1.7, 2.2 ± 1.6, 2.0 ± 1.6, and 2.1 ± 1.6, respectively. Disparities were partially explained by variations in individual, facility, and geographic covariates, but persisted after multivariable adjustments. Stratified analyses confirmed that disparities were similar in magnitude across patient and facility subgroups. Although nursing home residents showed overall low social engagement levels, racial/ethnic minority residents were even less socially engaged than white residents. Efforts to address disparities in psychosocial well-being and quality of life of nursing home residents are warranted.

Adjusting for Health Status in Non-Linear Models of Health Care Disparities

This article compared conceptual and empirical strengths of alternative methods for estimating racial disparities using non-linear models of health care access. Three methods were presented (propensity score, rank and replace, and a combined method) that adjust for health status while allowing SES variables to mediate the relationship between race and access to care. Applying these methods to a nationally representative sample of blacks and non-Hispanic whites surveyed in the 2003 and 2004 Medical Expenditure Panel Surveys (MEPS), we assessed the concordance of each of these methods with the Institute of Medicine (IOM) definition of racial disparities, and empirically compared the methods' predicted disparity estimates, the variance of the estimates, and the sensitivity of the estimates to limitations of available data. The rank and replace and combined methods (but not the propensity score method) are concordant with the IOM definition of racial disparities in that each creates a comparison group with the appropriate marginal distributions of health status and SES variables. Predicted disparities and prediction variances were similar for the rank and replace and combined methods, but the rank and replace method was sensitive to limitations on SES information. For all methods, limiting health status information significantly reduced estimates of disparities compared to a more comprehensive dataset. We conclude that the two IOM-concordant methods were similar enough that either could be considered in disparity predictions. In datasets with limited SES information, the combined method is the better choice. PMID:20352070

In 2005, the National Cancer Institute funded the Community Networks Program (CNP), which aimed to reduce cancer health disparities in minority racial/ethnic and underserved groups through community-based participatory research, education, and training. The purpose of this study was to describe the CNP model and their tobacco-related work in community-based research, education, and training using a tobacco disparities research framework. We conducted a comprehensive review of the CNP tobacco-related activities including publications, published abstracts, research activities, trainee pilot studies, policy-related activities, educational outreach, and reports produced from 2005-2009. Two authors categorized the tobacco-related activities and publications within the framework. Although there was no mandate to address tobacco, the CNPs produced 103 tobacco-related peer-reviewed publications, which reflects the largest proportion (12%) of all CNP cancer-related publications. Selected publications and research activities were most numerous under the framework areas "Psychosocial Research," "Surveillance," "Epidemiology," and "Treatment of Nicotine Addiction." Thirteen CNPs participated in tobacco control policymaking in mainstream efforts that affected their local community and populations, and 24 CNPs conducted 1147 tobacco-related educational outreach activities. CNP activities that aimed to build research and infrastructure capacity included nine tobacco-related pilot projects representing 16% of all CNP cancer-related pilot projects, and 17 publications acknowledging leveraged partnerships with other organizations, a strategy encouraged by the CNP. The CNP is a promising academic-community model for working to eliminate tobacco-related health disparities. Future efforts may address scientific gaps, consider collaboration across groups, assess the extent of operationalizing community-based participatory research, and improve common tracking measures. © The Author

Racial/ethnic disparities in preventing health problems have been reported in nursing homes. Incontinence is common among nursing home residents and can result in inflammatory-type skin damage, referred to as incontinence associated skin damage (IASD). Little is known about the prevention of IASD and whether there are racial/ethnic disparities in its prevention. This study assessed the proportion of older nursing home residents receiving IASD prevention after developing incontinence after admission (n=10,713) and whether there were racial/ethnic disparities in IASD prevention. Predictors of preventing IASD were also examined. Four national datasets provided potential predictors at multiple levels. Disparities were analyzed using the Peters-Belson method; predictors of preventing IASD were assessed using hierarchical logistic regression. Prevention of IASD was received by 0.12 of residents and no racial/ethnic disparities were found. Predictors of preventing IASD were primarily resident level factors including limitations in activities of daily living, poor nutrition, and more oxygenation problems. PMID:27586441

Socioeconomic disparities and health: impacts and pathways.

PubMed

Kondo, Naoki

2012-01-01

Growing socioeconomic disparity is a global concern, as it could affect population health. The author and colleagues have investigated the health impacts of socioeconomic disparities as well as the pathways that underlie those disparities. Our meta-analysis found that a large population has risks of mortality and poor self-rated health that are attributable to income inequality. The study results also suggested the existence of threshold effects (ie, a threshold of income inequality over which the adverse impacts on health increase), period effects (ie, the potential for larger impacts in later years, specifically after the 1990s), and lag effects between income inequality and health outcomes. Our other studies using Japanese national representative survey data and a large-scale cohort study of Japanese older adults (AGES cohort) support the relative deprivation hypothesis, namely, that invidious social comparisons arising from relative deprivation in an unequal society adversely affect health. A study with a natural experiment design found that the socioeconomic gradient in self-rated health might actually have become shallower after the 1997-98 economic crisis in Japan, due to smaller health improvements among middle-class white-collar workers and middle/upper-income workers. In conclusion, income inequality might have adverse impacts on individual health, and psychosocial stress due to relative deprivation may partially explain those impacts. Any study of the effects of macroeconomic fluctuations on health disparities should also consider multiple potential pathways, including expanding income inequality, changes in the labor market, and erosion of social capital. Further studies are needed to attain a better understanding of the social determinants of health in a rapidly changing society.

Objectives: Racial/ethnic disparities in nursing homes (NHs) are associated with lower quality of care, and state Medicaid payment policies may influence NH quality. However, no studies analyzing disparities in NH quality of life (QoL) exist. Therefore, this study aims to estimate associations at the NH level between average number of QoL deficiencies and concentrations of racial/ethnic minority residents, and to identify effects of state Medicaid payment policies on racial/ethnic disparities. Method: Multivariable Poisson regression with NH random effects was used to determine the association between NH minority concentration in 2000 to 2010 and average number of QoL deficiencies in 2001 to 2011 at the NH level, and the effect of state NH payment policies on QoL deficiencies and racial/ethnic disparities in QoL deficiencies across NH minority concentrations. Results: Racial/ethnic disparities in QoL between high and low minority concentration NHs decrease over time, but are not eliminated. Case mix payment was associated with an increased disparity between high and low minority concentration NHs in QoL deficiencies. Discussion: NH managers and policy makers should consider initiatives targeting minority residents or low-performing NHs with higher minority concentrations for improvement to reduce disparities and address QoL deficiencies.

Despite an accumulating body of literature addressing racial/ethnic disparities in children’s health and health care, there have been few published studies of interventions that have been successful in eliminating these disparities. The objectives of this article, therefore, are to (1) describe 3 interventions that have been successful in eliminating racial/ethnic disparities in children’s health and health care, (2) high-light tips and pitfalls regarding devising, implementing, and evaluating pediatric disparities interventions, and (3) propose a research agenda for pediatric disparities interventions. Key characteristics of the 3 successful interventions include rigorous study designs; large sample sizes; appropriate comparison groups; community-based interventions that are culturally and linguistically sensitive and involve collaboration with participants; research staff from the same community as the participants; appropriate blinding of outcomes assessors; and statistical adjustment of outcomes for relevant covariates. On the basis of these characteristics, I propose tips, pitfalls, an approach, and a research agenda for devising, implementing, and evaluating successful pediatric disparities interventions. Examination of 3 successful interventions indicates that pediatric health care disparities can be eliminated. Achievement of this goal requires an intervention that is rigorous, evidence-based, and culturally and linguistically appropriate. The intervention must also include community collaboration, minimize attrition, adjust for potential confounders, and incorporate mechanisms for sustainability. PMID:19861473

This study aimed to examine the socioeconomic disparities in health-related behaviors and to assess if behaviors eliminate socioeconomic disparities in oral health in a nationally representative sample of adult Americans. Data are from the US Third National Health and Nutrition Examination Survey (1988-1994). Behaviors were indicated by smoking, dental visits, frequency of eating fresh fruits and vegetables and extent of calculus, used as a marker for oral hygiene. Oral health outcomes were gingival bleeding, loss of periodontal attachment, tooth loss and perceived oral health. Education and income indicated socioeconomic position. Sex, age, ethnicity, dental insurance and diabetes were adjusted for in the regression analysis. Regression analysis was used to assess socioeconomic disparities in behaviors. Regression models adjusting and not adjusting for behaviors were compared to assess the change in socioeconomic disparities in oral health. The results showed clear socioeconomic disparities in all behaviors. After adjusting for behaviors, the association between oral health and socioeconomic indicators attenuated but did not disappear. These findings imply that improvement in health-related behaviors may lessen, but not eliminate socioeconomic disparities in oral health, and suggest the presence of more complex determinants of these disparities which should be addressed by oral health preventive policies.

While studies have consistently shown that in the USA, non-Hispanic Blacks (Blacks) have higher diabetes prevalence, complication and death rates than non-Hispanic Whites (Whites), there are no studies that compare disparities in diabetes mortality across the largest US cities. This study presents and compares Black/White age-adjusted diabetes mortality rate ratios (RRs), calculated using national death files and census data, for the 50 most populous US cities. Relationships between city-level diabetes mortality RRs and 12 ecological variables were explored using bivariate correlation analyses. Multivariate analyses were conducted using negative binomial regression to examine how much of the disparity could be explained by these variables. Blacks had statistically significantly higher mortality rates compared to Whites in 39 of the 41 cities included in analyses, with statistically significant rate ratios ranging from 1.57 (95 % CI: 1.33-1.86) in Baltimore to 3.78 (95 % CI: 2.84-5.02) in Washington, DC. Analyses showed that economic inequality was strongly correlated with the diabetes mortality disparity, driven by differences in White poverty levels. This was followed by segregation. Multivariate analyses showed that adjusting for Black/White poverty alone explained 58.5 % of the disparity. Adjusting for Black/White poverty and segregation explained 72.6 % of the disparity. This study emphasizes the role that inequalities in social and economic determinants, rather than for example poverty on its own, play in Black/White diabetes mortality disparities. It also highlights how the magnitude of the disparity and the factors that influence it can vary greatly across cities, underscoring the importance of using local data to identify context specific barriers and develop effective interventions to eliminate health disparities.

Implementing the Institute of Medicine definition of disparities: an application to mental health care.

PubMed

McGuire, Thomas G; Alegria, Margarita; Cook, Benjamin L; Wells, Kenneth B; Zaslavsky, Alan M

2006-10-01

In a recent report, the Institute of Medicine (IOM) defines a health service disparity between population groups to be the difference in treatment or access not justified by the differences in health status or preferences of the groups. This paper proposes an implementation of this definition, and applies it to disparities in outpatient mental health care. Health Care for Communities (HCC) reinterviewed 9,585 respondents from the Community Tracking Study in 1997-1998, oversampling individuals with psychological distress, alcohol abuse, drug abuse, or mental health treatment. The HCC is designed to make national estimates of service use. Expenditures are modeled using generalized linear models with a log link for quantity and a probit model for any utilization. We adjust for group differences in health status by transforming the entire distribution of health status for minority populations to approximate the white distribution. We compare disparities according to the IOM definition to other methods commonly used to assess health services disparities. Our method finds significant service disparities between whites and both blacks and Latinos. Estimated disparities from this method exceed those for competing approaches, because of the inclusion of effects of mediating factors (such as income) in the IOM approach. A rigorous definition of disparities is needed to monitor progress against disparities and to compare their magnitude across studies. With such a definition, disparities can be estimated by adjusting for group differences in models for expenditures and access to mental health services.

The Enduring Association between Education and Mortality: The Role of Widening and Narrowing Disparities

This paper examines how educational disparities in mortality emerge, grow, decline, and disappear across causes of death in the United States and how these change contribute to the enduring association of education and mortality over time. Focusing on adults age 40–64, we first examine the extent to which disparities in all-cause mortality by education persisted from 1989–2007. We then test the “fundamental cause” prediction that mortality disparities persist, in part, by shifting to new health outcomes over time, most importantly for those causes of death that have increasing mortality rates. To test this hypothesis, we focus in depth on the period from 1999–2007, when all causes of death were coded to the same classification system. The results indicate (a) both substantial widening and narrowing of mortality disparities across causes of death, (b) almost all causes of death that had increasing mortality rates also had widening disparities by education, and (c) the total disparity by education in all-cause mortality would be about 25% smaller today were it not for newly widened or emergent disparities since 1999. These results point to the theoretical and policy importance of identifying the social forces that cause health disparities to widen over time. PMID:26937041

To evaluate the level of competency and knowledge about health disparities among third-year doctor of pharmacy (PharmD) students at 2 Florida public colleges of pharmacy and to explore the demographic correlates of these variables. A cross-sectional survey study design was used to collect data from participants. The students had low health-disparities knowledge and moderate skills in dealing with sociocultural issues and cross-cultural encounters. Speaking a language(s) other than English and having exposure to cultural-competency instruction were the demographic variables found to be most significantly associated with clinical cultural competency and/or knowledge of health disparities. Clinical cultural competency and health-disparities instruction may not be adequately incorporated into the pharmacy school curricula in the institutions studied. Relevant education and training are necessary to enhance cultural competency among pharmacy students.

Racial and ethnic minorities have disproportionately higher cancer incidence and mortality than their White counterparts. In response to this inequity in cancer prevention and care, community-based lay health advisors (LHAs) may be suited to deliver effective, culturally relevant, quality cancer education, prevention/screening, and early detection services for underserved populations. APPROACH AND STRATEGIES: Consistent with key tenets of community-based participatory research (CBPR), this project engaged community partners to develop and implement a unique LHA training curriculum to address cancer health disparities among medically underserved communities in a tricounty area. Seven phases of curriculum development went into designing a final seven-module LHA curriculum. In keeping with principles of CBPR and community engagement, academic-community partners and LHAs themselves were involved at all phases to ensure the needs of academic and community partners were mutually addressed in development and implementation of the LHA program. Community-based LHA programs for outreach, education, and promotion of cancer screening and early detection, are ideal for addressing cancer health disparities in access and quality care. When community-based LHAs are appropriately recruited, trained, and located in communities, they provide unique opportunities to link, bridge, and facilitate quality cancer education, services, and research.

Despite Increased Insurance Coverage, Nonwhite Sexual Minorities Still Experience Disparities In Access To Care.

Previous studies suggest that members of sexual minority groups have poorer access to health services than heterosexuals. However, few studies have examined how sexual orientation interacts with gender and race to affect health care experience. Moreover, little is known about the role in health care disparities played by economic strains such as unemployment and poverty, which may result from prejudice and discrimination based on sexual orientation. Using data for 2013-15 from the National Health Interview Survey, we found that most members of sexual minority groups no longer have higher uninsurance rates than heterosexuals, but many continue to experience poorer access to high-quality care. Gay nonwhite men, bisexual white women, and bisexual and lesbian nonwhite women are disadvantaged in multiple aspects of access, compared to straight white men. Only some of these disparities are attributable to economic factors, which implies that noneconomic barriers to care are substantial. Our results suggest that the intersection of multiple social identities can reveal important gaps in health care experience. Making culturally sensitive services available may be key to closing the gaps. Project HOPE—The People-to-People Health Foundation, Inc.

Midwifery and health disparities: theories and intersections.

Cox, Kim J

2009-01-01

In the past decade, the reduction of health disparities has become an important policy agenda in the United States. Clinicians in practice, however, may be unfamiliar with the prevailing causal theories and uncertain about what they can do to help to reduce inequalities in health. The purpose of this article is to provide women's health care clinicians with an overview of the definitions, measurement issues, and theories that fall under the rubric of health disparities. The intersecting roles of genetics, race/ethnicity, environment, and gender are discussed. The article also provides practical suggestions for interventions and health policy change that can be implemented by clinicians in practice.

Area-socioeconomic disparities in mental health service use among children involved in the child welfare system.

Relying on data from a nationally representative sample of youth involved in the child welfare system (CWS) in 1999-2000 (the National Survey of Child and Adolescent Well-Being, Cohort 1) and 2008-2009 (Cohort 2), this study implemented a diverse set of disparity indicators to estimate area-socioeconomic disparities in mental health (MH) services use and changes in area-socioeconomic disparities between the two cohorts. Our study found that there are area-socioeconomic disparities in MH service use, indicating that the rates of MH service use among youth referred to the CWS differ by area-socioeconomic positions defined by county-level poverty rates. We also found that area-socioeconomic disparities increased over time. However, the magnitude of the increase varied widely across disparity measures, suggesting that there are different conclusions about the trend and magnitude of area-socioeconomic disparities, depending upon which disparity measures are implemented. A greater understanding of the methodological differences among disparity measures is warranted, which will in turn impact how interventions are designed to reduce socioeconomic disparities among children in the CWS.

2008-01-01

Background While Arab countries showed an impressive decline in child mortality rates during the past few decades, gaps in mortality by gender and socioeconomic status persisted. However, large socioeconomic disparities in child health were evident in almost every country in the region. Methods Using available tabulations and reliable micro data from national household surveys, data for 18 Arab countries were available for analysis. In addition to infant and child mortality, child health was measured by nutritional status, vaccination, and Acute Respiratory Infection (ARI). Within-country disparities in child health by gender, residence (urban/rural) and maternal educational level were described. Child health was also analyzed by macro measures of development, including per capita GDP (PPP), female literacy rates, urban population and doctors per 100,000 people. Results Gender disparities in child health using the above indicators were less evident, with most showing clear female advantage. With the exception of infant and child survival, gender disparities demonstrated a female advantage, as well as a large urban advantage and an overall advantage for mothers with secondary education. Surprisingly, the countries' rankings with respect to disparities were not associated with various macro measures of development. Conclusion The tenacity of pervasive intra-country socioeconomic disparities in child health calls for attention by policy makers and health practitioners. PMID:19021903

Review: Increasing Awareness and Education on Health Disparities for Health Care Providers

Nesbitt, Shawna; Palomarez, Rigo Estevan

2016-01-01

The focus of this review is to highlight health care disparities and trends in several common diseases in selected populations while offering evidence-based approaches to mitigating health care disparities. Health care disparities cross many barriers and affect multiple populations and diseases. Ethnic minorities, the elderly, and those of lower socioeconomic status (SES) are more at-risk than others. However, many low SES Whites and higher SES racial minorities have poorer health than their racial or SES peers. Also, recent immigrant groups and Hispanics, in particular, maintain high health ratings. The so-called Hispanic Paradox provides an example of how culture and social background can be used to improve health outcomes. These groups have unique determinants of disparity that are based on a wide range of cultural and societal factors. Providing improved access to care and reducing the social determinants of disparity is crucial to improving public health. At the same time, for providers, increasing an understanding of the social determinants promotes better models of individualized care to encourage more equitable care. These approaches include increasing provider education on disparities encountered by different populations, practicing active listening skills, and utilizing a patient’s cultural background to promote healthy behaviors PMID:27103768

Disparity in smoking prevalence by education: can we reduce it?

2010-03-01

Can an intervention program that is highly effective in reducing the prevalence of an unhealthy behavior in the general population also reduce the disparity among its subgroups? That depends on what measure of disparity is used. Using simple algebraic models, this study demonstrates that disparity measured in terms of relative difference between two groups tends to increase when the prevalence of the behavior is in decline. The study then shows an empirical example, by analyzing the effects of the California tobacco control program on smoking prevalence of two education groups, the lowest (less than 12 years) and the highest (16 years or more). It examines the data from four California Tobacco Surveys covering the years 1996, 1999, 2002, and 2005. The effects of three components of the tobacco control program known to be effective in decreasing prevalence (media, worksite policy, and price) on the two education groups are assessed. The smoking prevalence for the two groups is obtained from these four surveys and a regression line is computed for each education group from 1996 to 2005. Results show that the California program is effective with both low education and high education groups and that the rate of decline in smoking prevalence from 1996 to 2005 is no smaller for the low education group than for the high education group. The paper then discusses that an analysis of disparity based on relative difference, however, could result in misleading recommendations that an intervention like the California tobacco program needs to change from its current whole-population approach to one that focuses on targeting subgroups because it has not reduced disparity. It proposes that research should focus more on increasing the rate of change among less advantage groups and less on the relative disparity compared to some other group.

Sleep as a Potential Fundamental Contributor to Cardiovascular Health Disparities

Jackson, Chandra L.; Redline, Susan; Emmons, Karen M.

2016-01-01

Optimal sleep is integral to health but is commonly not obtained. Despite its wide ranging public health impact, sleep health is under-appreciated by the general public and is only rarely considered by policy makers, employers, schools, and others whose policies and structures can adversely affect sleep. Inadequate sleep duration and quality are prevalent in minority and low-income populations and may play a fundamental role in racial and socioeconomic status (SES) inequities for a wide range of health conditions including cardiovascular disease (CVD).The goal of this review is to examine the relationship between sleep and CVD health disparities. To this end, we describe the overall public health importance of sleep and the role of sleep duration as well as the two most common disorders (sleep apnea and insomnia) as risk factors for a number of chronic diseases. We then focus on the potential link between sleep and CVD disparities. A multilevel model developed for the analysis of population health and health disparities as a part of the National Cancer Institute’s Centers on Population Health and Health Disparities served as our conceptual framework. It is based on the notion that individual behaviors, like sleep, are influenced by complex and dynamic interrelations among the individual and his or her physical and social environments across the lifespan. Using this model, we describe modifiable factors that contribute to insufficient sleep and circadian misalignment, propose potential interventions in various sectors (e.g. neighborhoods, schools, workplaces) that address social structures that contribute to disparities, and conclude by recommending critical areas for future sleep research. We ultimately suggest that integrating sleep into public health research will identify novel approaches for closing the gap in health disparities, such as CVD. PMID:25785893

Same-Sex and Race-Based Disparities in Statutory Rape Arrests.

Chaffin, Mark; Chenoweth, Stephanie; Letourneau, Elizabeth J

2016-01-01

This study tests a liberation hypothesis for statutory rape incidents, specifically that there may be same-sex and race/ethnicity arrest disparities among statutory rape incidents and that these will be greater among statutory rape than among forcible sex crime incidents. 26,726 reported incidents of statutory rape as defined under state statutes and 96,474 forcible sex crime incidents were extracted from National Incident-Based Reporting System data sets. Arrest outcomes were tested using multilevel modeling. Same-sex statutory rape pairings were rare but had much higher arrest odds. A victim-offender romantic relationship amplified arrest odds for same-sex pairings, but damped arrest odds for male-on-female pairings. Same-sex disparities were larger among statutory than among forcible incidents. Female-on-male incidents had uniformly lower arrest odds. Race/ethnicity effects were smaller than gender effects and more complexly patterned. The findings support the liberation hypothesis for same-sex statutory rape arrest disparities, particularly among same-sex romantic pairings. Support for race/ethnicity-based arrest disparities was limited and mixed. © The Author(s) 2014.

Probabilistic choice between symmetric disparities in motion stereo matching for a lateral navigation system

Ershov, Egor; Karnaukhov, Victor; Mozerov, Mikhail

2016-02-01

Two consecutive frames of a lateral navigation camera video sequence can be considered as an appropriate approximation to epipolar stereo. To overcome edge-aware inaccuracy caused by occlusion, we propose a model that matches the current frame to the next and to the previous ones. The positive disparity of matching to the previous frame has its symmetric negative disparity to the next frame. The proposed algorithm performs probabilistic choice for each matched pixel between the positive disparity and its symmetric disparity cost. A disparity map obtained by optimization over the cost volume composed of the proposed probabilistic choice is more accurate than the traditional left-to-right and right-to-left disparity maps cross-check. Also, our algorithm needs two times less computational operations per pixel than the cross-check technique. The effectiveness of our approach is demonstrated on synthetic data and real video sequences, with ground-truth value.

OBJECTIVES We examined racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis and medication use and determined whether medication disparities were more likely due to underdiagnosis or undertreatment of African-American and Latino children, or overdiagnosis or overtreatment of white children. METHODS We used a population-based, multisite sample of 4297 children and parents surveyed over 3 waves (fifth, seventh, and 10th grades). Multivariate logistic regression examined disparities in parent-reported ADHD diagnosis and medication use in the following analyses: (1) using the total sample; (2) limited to children with an ADHD diagnosis or symptoms; and (3) limited to children without a diagnosis or symptoms. RESULTS Across all waves, African-American and Latino children, compared with white children, had lower odds of having an ADHD diagnosis and of taking ADHD medication, controlling for sociodemographics, ADHD symptoms, and other potential comorbid mental health symptoms. Among children with an ADHD diagnosis or symptoms, African-American children had lower odds of medication use at fifth, seventh, and 10th grades, and Latino children had lower odds at fifth and 10th grades. Among children who had neither ADHD symptoms nor ADHD diagnosis by fifth grade (and thus would not likely meet ADHD diagnostic criteria at any age), medication use did not vary by race/ethnicity in adjusted analysis. CONCLUSIONS Racial/ethnic disparities in parent-reported medication use for ADHD are robust, persisting from fifth grade to 10th grade. These findings suggest that disparities may be more likely related to underdiagnosis and undertreatment of African-American and Latino children as opposed to overdiagnosis or overtreatment of white children.

When does power disparity help or hurt group performance?

PubMed

Tarakci, Murat; Greer, Lindred L; Groenen, Patrick J F

2016-03-01

Power differences are ubiquitous in social settings. However, the question of whether groups with higher or lower power disparity achieve better performance has thus far received conflicting answers. To address this issue, we identify 3 underlying assumptions in the literature that may have led to these divergent findings, including a myopic focus on static hierarchies, an assumption that those at the top of hierarchies are competent at group tasks, and an assumption that equality is not possible. We employ a multimethod set of studies to examine these assumptions and to understand when power disparity will help or harm group performance. First, our agent-based simulation analyses show that by unpacking these common implicit assumptions in power research, we can explain earlier disparate findings--power disparity benefits group performance when it is dynamically aligned with the power holder's task competence, and harms group performance when held constant and/or is not aligned with task competence. Second, our empirical findings in both a field study of fraud investigation groups and a multiround laboratory study corroborate the simulation results. We thereby contribute to research on power by highlighting a dynamic understanding of power in groups and explaining how current implicit assumptions may lead to opposing findings.

Understanding and Addressing Racial Disparities in Health Care

Racial disparities in medical care should be understood within the context of racial inequities in societal institutions. Systematic discrimination is not the aberrant behavior of a few but is often supported by institutional policies and unconscious bias based on negative stereotypes. Effectively addressing disparities in the quality of care requires improved data systems, increased regulatory vigilance, and new initiatives to appropriately train medical professionals and recruit more providers from disadvantaged minority backgrounds. Identifying and implementing effective strategies to eliminate racial inequities in health status and medical care should be made a national priority. PMID:11481746

Binocular disparity tuning and visual-vestibular congruency of multisensory neurons in macaque parietal cortex

2012-01-01

Many neurons in the dorsal medial superior temporal (MSTd) and ventral intraparietal (VIP) areas of the macaque brain are multisensory, responding to both optic flow and vestibular cues to self-motion. The heading tuning of visual and vestibular responses can be either congruent or opposite, but only congruent cells have been implicated in cue integration for heading perception. Because of the geometric properties of motion parallax, however, both congruent and opposite cells could be involved in coding self-motion when observers fixate a world-fixed target during translation, if congruent cells prefer near disparities and opposite cells prefer far disparities. We characterized the binocular disparity selectivity and heading tuning of MSTd and VIP cells using random-dot stimuli. Most (70%) MSTd neurons were disparity-selective with monotonic tuning, and there was no consistent relationship between depth preference and congruency of visual and vestibular heading tuning. One-third of disparity-selective MSTd cells reversed their depth preference for opposite directions of motion (direction-dependent disparity tuning, DDD), but most of these cells were unisensory with no tuning for vestibular stimuli. Inconsistent with previous reports, the direction preferences of most DDD neurons do not reverse with disparity. By comparison to MSTd, VIP contains fewer disparity-selective neurons (41%) and very few DDD cells. On average, VIP neurons also preferred higher speeds and nearer disparities than MSTd cells. Our findings are inconsistent with the hypothesis that visual/vestibular congruency is linked to depth preference, and also suggest that DDD cells are not involved in multisensory integration for heading perception.

McGuire, Thomas G; Alegria, Margarita; Cook, Benjamin L; Wells, Kenneth B; Zaslavsky, Alan M

2006-01-01

Objective In a recent report, the Institute of Medicine (IOM) defines a health service disparity between population groups to be the difference in treatment or access not justified by the differences in health status or preferences of the groups. This paper proposes an implementation of this definition, and applies it to disparities in outpatient mental health care. Data Sources Health Care for Communities (HCC) reinterviewed 9,585 respondents from the Community Tracking Study in 1997–1998, oversampling individuals with psychological distress, alcohol abuse, drug abuse, or mental health treatment. The HCC is designed to make national estimates of service use. Study Design Expenditures are modeled using generalized linear models with a log link for quantity and a probit model for any utilization. We adjust for group differences in health status by transforming the entire distribution of health status for minority populations to approximate the white distribution. We compare disparities according to the IOM definition to other methods commonly used to assess health services disparities. Principal Findings Our method finds significant service disparities between whites and both blacks and Latinos. Estimated disparities from this method exceed those for competing approaches, because of the inclusion of effects of mediating factors (such as income) in the IOM approach. Conclusions A rigorous definition of disparities is needed to monitor progress against disparities and to compare their magnitude across studies. With such a definition, disparities can be estimated by adjusting for group differences in models for expenditures and access to mental health services. PMID:16987312

Report cards have been used to increase accountability and quality of care in health care settings, and to improve state infrastructure for providing quality mental health care services. However, to date, report cards have not been used to compare states on racial/ethnic disparities in mental health care. This qualitative study examines reactions of mental health care policymakers to a proposed mental health care disparities report card generated from population-based survey data of mental health and mental health care utilization. We elicited feedback about the content, format, and salience of the report card. Interviews were conducted with nine senior advisors to state policymakers and one policy director of a national non-governmental organization from across the U.S. Four primary themes emerged: fairness in state-by-state comparisons; disconnect between the goals and language of policymakers and researchers; concerns about data quality and; targeted suggestions from policymakers. Participant responses provide important information that can contribute to making evidence-based research more accessible to policymakers. Further, policymakers suggested ways to improve the structure and presentation of report cards to make them more accessible to policymakers and to foster equity considerations during the implementation of new health care legislation. To reduce mental health care disparities, effort is required to facilitate understanding between researchers and relevant stakeholders about research methods, standards for interpretation of research-based evidence and its use in evaluating policies aimed at ameliorating disparities.

Background This article introduces some key labor, economic, and social policies that historically and currently impact occupational health disparities in the United States. Methods We conducted a broad review of the peer-reviewed and gray literature on the effects of social, economic, and labor policies on occupational health disparities. Results Many populations such as tipped workers, public employees, immigrant workers, and misclassified workers are not protected by current laws and policies, including worker’s compensation or Occupational Safety and Health Administration enforcement of standards. Local and state initiatives, such as living wage laws and community benefit agreements, as well as multiagency law enforcement contribute to reducing occupational health disparities. Conclusions There is a need to build coalitions and collaborations to command the resources necessary to identify, and then reduce and eliminate occupational disparities by establishing healthy, safe, and just work for all.

Identification of racial disparities in breast cancer mortality: does scale matter?

This paper investigates the impact of geographic scale (census tract, zip code, and county) on the detection of disparities in breast cancer mortality among three ethnic groups in Texas (period 1995-2005). Racial disparities were quantified using both relative (RR) and absolute (RD) statistics that account for the population size and correct for unreliable rates typically observed for minority groups and smaller geographic units. Results were then correlated with socio-economic status measured by the percentage of habitants living below the poverty level. African-American and Hispanic women generally experience higher mortality than White non-Hispanics, and these differences are especially significant in the southeast metropolitan areas and southwest border of Texas. The proportion and location of significant racial disparities however changed depending on the type of statistic (RR versus RD) and the geographic level. The largest proportion of significant results was observed for the RD statistic and census tract data. Geographic regions with significant racial disparities for African-Americans and Hispanics frequently had a poverty rate above 10.00%. This study investigates both relative and absolute racial disparities in breast cancer mortality between White non-Hispanic and African-American/Hispanic women at the census tract, zip code and county levels. Analysis at the census tract level generally led to a larger proportion of geographical units experiencing significantly higher mortality rates for minority groups, although results varied depending on the use of the relative versus absolute statistics. Additional research is needed before general conclusions can be formulated regarding the choice of optimal geographic regions for the detection of racial disparities.

Addressing the Social Determinants of Health to Reduce Tobacco-Related Disparities

Introduction Comprehensive tobacco prevention and control efforts that include implementing smoke-free air laws, increasing tobacco prices, conducting hard-hitting mass media campaigns, and making evidence-based cessation treatments available are effective in reducing tobacco use in the general population. However, if these interventions are not implemented in an equitable manner, certain population groups may be left out causing or exacerbating disparities in tobacco use. Disparities in tobacco use have, in part, stemmed from inequities in the way tobacco control policies and programs have been adopted and implemented to reach and impact the most vulnerable segments of the population that have the highest rates of smokings (e.g., those with lower education and incomes). Methods Education and income are the 2 main social determinants of health that negatively impact health. However, there are other social determinants of health that must be considered for tobacco control policies to be effective in reducing tobacco-related disparities. This article will provide an overview of how tobacco control policies and programs can address key social determinants of health in order to achieve equity and eliminate disparities in tobacco prevention and control. Results Tobacco control policy interventions can be effective in addressing the social determinants of health in tobacco prevention and control to achieve equity and eliminate tobacco-related disparities when they are implemented consistently and equitably across all population groups. Conclusions Taking a social determinants of health approach in tobacco prevention and control will be necessary to achieve equity and eliminate tobacco-related disparities. PMID:25516538

Racial and ethnic disparities in the receipt of cancer treatment.

Shavers, Vickie L; Brown, Martin L

2002-03-06

A disproportionate number of cancer deaths occur among racial/ethnic minorities, particularly African Americans, who have a 33% higher risk of dying of cancer than whites. Although differences in incidence and stage of disease at diagnosis may contribute to racial disparities in mortality, evidence of racial disparities in the receipt of treatment of other chronic diseases raises questions about the possible role of inequities in the receipt of cancer treatment. To evaluate racial/ethnic disparities in the receipt of cancer treatment, we examined the published literature that addressed access/use of specific cancer treatment procedures, trends in patterns of use, or survival studies. We found evidence of racial disparities in receipt of definitive primary therapy, conservative therapy, and adjuvant therapy. These treatment differences could not be completely explained by racial/ethnic variation in clinically relevant factors. In many studies, these treatment differences were associated with an adverse impact on the health outcomes of racial/ethnic minorities, including more frequent recurrence, shorter disease-free survival, and higher mortality. Reducing the influence of nonclinical factors on the receipt of cancer treatment may, therefore, provide an important means of reducing racial/ethnic disparities in health. New data resources and improved study methodology are needed to better identify and quantify the full spectrum of nonclinical factors that contribute to the higher cancer mortality among racial/ethnic minorities and to develop strategies to facilitate receipt of appropriate cancer care for all patients.

Eliminating the cost of vaccines as a barrier to vaccination was one strategy of the Childhood Immunization Initiative; it led to Congressional legislation that authorized creation of the Vaccines for Children program (VFC) in 1994. CDC analyzed National Immunization Survey data for 1995-2011 to evaluate trends in disparities in vaccination coverage rates between non-Hispanic white children and children of other racial/ethnic groups. VFC has been effective in ireducing disparities in vaccination coverage among U.S. children. CDC's Office of Minority Health and Health Equity selected the intervention analysis and discussion that follows to provide an example of a program that has been effective in reducing childhood vaccination coverage-related disparities in the United States. At its inception in 1994, VFC was implemented in 78 Immunization Action Plan areas that covered the entire United States; within each area, concerted efforts were made to improve childhood vaccination coverage. The findings in this report demonstrate that there have been no racial/ethnic disparities in vaccine coverage for measles-mumps-rubella and poliovirus in the United States since 2005. Disparities in coverage for the diphtheria-tetanus-pertussis/diphtheria-tetanus-acellular pertussis vaccine were absent, declining, or inconsistent during this period, depending on the racial/ethnic group examined. The results in this report highlight the effectiveness of VFC.

Examining Sexual Orientation Disparities in Unmet Medical Needs among Men and Women

Using the National Longitudinal Study of Adolescent Health (N = 13,810), this study examines disparities in unmet medical needs by sexual orientation identity during young adulthood. We use binary logistic regression and expand Andersen’s health care utilization framework to identify factors that shape disparities in unmet medical needs by sexual orientation. We also investigate whether the well-established gender disparity in health-seeking behaviors among heterosexual persons holds for sexual minorities. The results show that sexual minority women are more likely to report unmet medical needs than heterosexual women, but no differences are found between sexual minority and heterosexual men. Moreover, we find a reversal in the gender disparity between heterosexual and sexual minority populations: heterosexual women are less likely to report unmet medical needs than heterosexual men, whereas sexual minority women are more likely to report unmet medical needs compared to sexual minority men. Finally, this work advances Andersen’s model by articulating the importance of including social psychological factors for reducing disparities in unmet medical needs by sexual orientation for women.

Walker, Bailus; Mays, Vickie M.; Warren, Rueben

2013-01-01

The elimination of racial/ethnic health status disparities is a compelling national health objective. It was etched in sharp relief by the 1985 report of the U.S. Department of Health and Human Services Secretary’s Task Force on Black and Minority Health and considerable attention has been devoted to the problem since that report. But the problem persists, disparities are not fully explained and effective policies to reduce them have been elusive, a situation presenting both opportunities and challenges. Important advances towards reducing racial/ethnic health disparities may be made by better understanding the complex bidirectional relationship between and among the multiple factors, biological and non-biological, influencing morbidity and mortality. The landscape in which these influences are felt is anything but static. In this paper selected components of the landscape that are critical to the elimination of racial/ethnic health status disparities are reviewed. These factors underscore the importance of adopting and maintaining a perspective on health disparities that encompasses a broad array of health determinants. PMID:15531810

Racial/ethnic, gender, and age disparities in access to renal transplantation among end-stage renal disease (ESRD) patients have been well documented, but few studies have explored health care staff attitudes towards these inequalities. Staff perceptions can influence patient care and outcomes, and identifying staff perceptions on disparities could aid in the development of potential interventions to address these health inequities. The objective of this study was to investigate dialysis staff (n = 509), primarily social workers and nurse managers, perceptions of renal transplant disparities in the Southeastern United States. This is a mixed methods study that uses both deductive and inductive qualitative analysis of a dialysis staff survey conducted in 2012 using three open-ended questions that asked staff to discuss their perceptions of factors that may contribute to transplant disparities among African American, female, and elderly patients. Study results suggested that the majority of staff (n = 255, 28%) perceived patients' low socioeconomic status as the primary theme related to why renal transplant disparities exist between African Americans and non-Hispanic whites. Staff cited patient perception of old age as a primary contributor (n = 188, 23%) to the disparity between young and elderly patients. The dialysis staff responses on gender transplant disparities suggested that staff were unaware of differences due to limited experience and observation (n = 76, 14.7%) of gender disparities. These findings suggest that dialysis facilities should educate staff on existing renal transplantation disparities, particularly gender disparities, and collaboratively work with transplant facilities to develop strategies to actively address modifiable patient barriers for transplant.

Measuring racial/ethnic disparities across the distribution of health care expenditures.

To assess whether black-white and Hispanic-white disparities increase or abate in the upper quantiles of total health care expenditure, conditional on covariates. Nationally representative adult population of non-Hispanic whites, African Americans, and Hispanics from the 2001-2005 Medical Expenditure Panel Surveys. We examine unadjusted racial/ethnic differences across the distribution of expenditures. We apply quantile regression to measure disparities at the median, 75th, 90th, and 95th quantiles, testing for differences over the distribution of health care expenditures and across income and education categories. We test the sensitivity of the results to comparisons based only on health status and estimate a two-part model to ensure that results are not driven by an extremely skewed distribution of expenditures with a large zero mass. Black-white and Hispanic-white disparities diminish in the upper quantiles of expenditure, but expenditures for blacks and Hispanics remain significantly lower than for whites throughout the distribution. For most education and income categories, disparities exist at the median and decline, but remain significant even with increased education and income. Blacks and Hispanics receive significantly disparate care at high expenditure levels, suggesting prioritization of improved access to quality care among minorities with critical health issues.

Regional Disparities in Online Map User Access Volume and Determining Factors

The regional disparities of online map user access volume (use `user access volume' in this paper to indicate briefly) is a topic of growing interest with the increment of popularity in public users, which helps to target the construction of geographic information services for different areas. At first place we statistically analysed the online map user access logs and quantified these regional access disparities on different scales. The results show that the volume of user access is decreasing from east to the west in China as a whole, while East China produces the most access volume; these cities are also the crucial economic and transport centres. Then Principal Component Regression (PCR) is applied to explore the regional disparities of user access volume. A determining model for Online Map access volume is proposed afterwards, which indicates that area scale is the primary determining factor for regional disparities, followed by public transport development level and public service development level. Other factors like user quality index and financial index have very limited influence on the user access volume. According to the study of regional disparities in user access volume, map providers can reasonably dispatch and allocate the data resources and service resources in each area and improve the operational efficiency of the Online Map server cluster.

Seeing voices of health disparity: evaluating arts projects as influence processes.

Arts-informed approaches are increasingly popular as vehicles for research, knowledge translation and for engaging key stakeholders on topics of health and health care. This paper describes an evaluation of a multimedia art installation intended to promote awareness of health disparities as experienced by homeless persons living in Toronto (Canada). The objective of the evaluation was to determine whether the installation had an impact on audience members, and if so, to understand its influence on viewers' perspectives on homelessness and the health concerns of homeless persons. Key themes were identified through the analysis of direct observational data of viewer interactions with the exhibit and qualitative interviews with different audience members after the exhibit. The four key themes were: (1) Promoting recognition of common humanity between viewers and viewed (challenging previously held assumptions and stereotypes, narrowing perceived social distance); (2) functions fulfilled (or potentially fulfilled) by the exhibit: raising awareness, educational applications, and potential pathways by which the exhibit could serve as a call to social action; (3) stories that prompt more stories: the stories within the exhibit (coupled with the interview questions) prompted further sharing of stories amongst the evaluation respondents, highlighting the iterative nature of such approaches. Respondents told of recognizing similarities in the experiences recounted in the exhibit with their own interactions with homeless persons; (4) strengths and weaknesses identified: including aesthetic features, issues of audience 'reach' and the importance of suitable venues for exhibition. Theoretically informed by narrative analysis and visual anthropology, this evaluation demonstrates that arts-informed 'interventions' are highly complex and work in subtle ways on viewers, allowing them to re-imagine the lives of others and identify points of common interest.

Objective Recent studies have highlighted disparities in cancer diagnosis between lesbian, gay, bisexual and transgender (LGBT) and heterosexual adults. Studies have yet to examine disparities between LGBT and heterosexual cancer survivors in prevalence of psychological distress. Methods Data for the current study were drawn from the LIVESTRONG dataset, a US national survey that sampled 207 LGBT and 4899 heterosexual cancer survivors (all cancer types, 63.5% women, mean age 49) in 2010. Symptoms of psychological distress were assessed with dichotomous yes/no items in three symptom clusters (depression related to cancer, difficulties with social relationships post-cancer, fatigue/energy problems). We selected a sample of 621 heterosexual survivors matched by propensity score to the 207 LGBT survivors and assessed disparities in count of symptoms using Poisson regression. We also performed subgroup analyses by self-reported sex. Results Relative to heterosexuals, LGBT cancer survivors reported a higher number of depression and relationship difficulty symptoms. Exploratory analyses revealed that disparities in number of symptoms were visible between gay, bisexual, and transgender versus heterosexual men but not between lesbian, bisexual, and transgender versus heterosexual women. Conclusions This study highlights several disparities in psychological distress that exist between LGBT and heterosexual survivors. A need remains for interventions tailored to LGBT survivors and for studies examining disparities within subgroups of LGBT survivors. PMID:25630987

Racial and Ethnic Disparities in the VA Health Care System: A Systematic Review

Objectives To better understand the causes of racial disparities in health care, we reviewed and synthesized existing evidence related to disparities in the “equal access” Veterans Affairs (VA) health care system. Methods We systematically reviewed and synthesized evidence from studies comparing health care utilization and quality by race within the VA. Results Racial disparities in the VA exist across a wide range of clinical areas and service types. Disparities appear most prevalent for medication adherence and surgery and other invasive procedures, processes that are likely to be affected by the quantity and quality of patient–provider communication, shared decision making, and patient participation. Studies indicate a variety of likely root causes of disparities including: racial differences in patients’ medical knowledge and information sources, trust and skepticism, levels of participation in health care interactions and decisions, and social support and resources; clinician judgment/bias; the racial/cultural milieu of health care settings; and differences in the quality of care at facilities attended by different racial groups. Conclusions Existing evidence from the VA indicates several promising targets for interventions to reduce racial disparities in the quality of health care. PMID:18301951

Slow and steady: the evolution of cranial disparity in fossil and recent turtles.

PubMed

Foth, Christian; Joyce, Walter G

2016-11-30

Turtles (Testudinata) are a diverse group of amniotes that have a rich fossil record that extends back to the Late Triassic, but little is known about global patterns of disparity through time. We here investigate the cranial disparity of 172 representatives of the turtle lineage and their ancestors grouped into 20 time bins ranging from the Late Triassic until the Recent using two-dimensional geometric morphometrics. Three evolutionary phases are apparent in all three anatomical views investigated. In the first phase, disparity increases gradually from the Late Triassic to the Palaeogene with only a minor perturbation at the K/T extinct event. Although global warming may have influenced this increase, we find the Mesozoic fragmentation of Pangaea to be a more plausible factor. Following its maximum, disparity decreases strongly towards the Miocene, only to recover partially towards the Recent. The marked collapse in disparity is likely a result of habitat destruction caused by global drying, combined with the homogenization of global turtle faunas that resulted from increased transcontinental dispersal in the Tertiary. The disparity minimum in the Miocene is likely an artefact of poor sampling. © 2016 The Author(s).

2010-01-01

Translational, transdisciplinary, and transformational research stands to become a paradigm-shifting mantra for research in health disparities. A windfall of research discoveries using these 3 approaches has increased our understanding of the health disparities in racial, ethnic, and low socioeconomic status groups. These distinct but related research spheres possess unique environments, which, when integrated, can lead to innovation in health disparities science. In this article, we review these approaches and propose integrating them to advance health disparities research through a change in philosophical position and an increased emphasis on community engagement. We argue that a balanced combination of these research approaches is needed to inform evidence-based practice, social action, and effective policy change to improve health in disparity communities.

Despite staggering investments made in unraveling the human genome, current estimates suggest that as much as 90% of the variance in cancer and chronic diseases can be attributed to factors outside an individual’s genetic endowment, particularly to environmental exposures experienced across his or her life course. New analytical approaches are clearly required as investigators turn to complicated systems theory and ecological, place-based and life-history perspectives in order to understand more clearly the relationships between social determinants, environmental exposures and health disparities. While traditional data analysis techniques remain foundational to health disparities research, they are easily overwhelmed by the ever-increasing size and heterogeneity of available data needed to illuminate latent gene x environment interactions. This has prompted the adaptation and application of scalable combinatorial methods, many from genome science research, to the study of population health. Most of these powerful tools are algorithmically sophisticated, highly automated and mathematically abstract. Their utility motivates the main theme of this paper, which is to describe real applications of innovative transdisciplinary models and analyses in an effort to help move the research community closer toward identifying the causal mechanisms and associated environmental contexts underlying health disparities. The public health exposome is used as a contemporary focus for addressing the complex nature of this subject. PMID:25310540

The Value of Friction, Tension, and Disparity in Global Collaboration (Invited)

NASA Astrophysics Data System (ADS)

Parsons, M. A.

2013-12-01

Misunderstandings; conflicting goals; competition for limited funds; differing worldviews, agendas, ideals... These types of 'friction' are inevitable in national and global collaboration. And while friction can create tension and conflict, it is not inherently bad. It is at these points of interaction and tension where we can sometimes gain the most insight. Common understanding comes not only through agreed universal principles but also through multiple lines of evidence that wind through disparate views and describe a greater story. Collaboration is not straightforward in an environment of friction, tension, and disparity. Collaborators do not necessarily have common goals. Dynamic, coalition-style politics emerge. How can we align these disparities to achieve standards and common knowledge while still valuing and understanding differing perspectives? Achieving the understanding that comes through both unity and disparity is a central goal of the Research Data Alliance. RDA is emerging as a "neutral place" or "social gateway" where frictions can be identified, addressed, and understood but not necessarily removed.

Toward a Fourth Generation of Disparities Research to Achieve Health Equity

2011-01-01

Achieving health equity, driven by the elimination of health disparities, is a goal of Healthy People 2020. In recent decades, the improvement in health status has been remarkable for the U.S. population as a whole. However, racial and ethnic minority populations continue to lag behind whites with a quality of life diminished by illness from preventable chronic diseases and a life span cut short by premature death. We examine a conceptual framework of three generations of health disparities research to understand (a) data trends, (b) factors driving disparities, and (c) solutions for closing the gap. We propose a new, fourth generation of research grounded in public health critical race praxis, utilizing comprehensive interventions to address race, racism, and structural inequalities and advancing evaluation methods to foster our ability to eliminate disparities. This new generation demands that we address the researcher’s own biases as part of the research process. PMID:21219164

The role of food culture and marketing activity in health disparities.

2012-11-01

Marketing activities have attracted increased attention from scholars interested in racial disparities in obesity prevalence, as well as the prevalence of other preventable conditions. Although reducing the marketing of nutritionally poor foods to racial/ethnic communities would represent a significant step forward in eliminating racial disparities in health, we focus instead on a critical-related question. What is the relationship between marketing activities, food culture, and health disparities? This commentary posits that food culture shapes the demand for food and the meaning attached to particular foods, preparation styles, and eating practices, while marketing activities shape the overall environment in which food choices are made. We build on prior research that explores the socio-cultural context in which marketing efforts are perceived and interpreted. We discuss each element of the marketing mix to highlight the complex relationship between food culture, marketing activities, and health disparities. Copyright © 2011 Elsevier Inc.

Medical Home Disparities for Latino Children by Parental Language of Interview

PubMed Central

DeCamp, Lisa Ross; Choi, Hwajung; Davis, Matthew M.

2015-01-01

Examination of Latino children in aggregate ignores important subgroup differences due to the parents’ English language ability. Previous reports of the pediatric medical home have not stratified Latino children by parental language differences to compare the two groups directly. We analyzed the 2007 National Survey of Children’s Health to determine medical home prevalence among Latino children, stratified by language of parental interview. Most Latino children with a Spanish-language parental interview had a usual source of care, but only one-quarter had a medical home. Striking medical home disparities persisted for Latino children with a Spanish-language interview, even after adjustment for potential confounders. Lack of a medical home was associated with disparities in the quality of care, more so than access disparities. Addressing health care disparities for Latino children requires particular attention to the unique needs of Latino children with parents who may experience language barriers during health care encounters.

Sequences corresponding to some of the polymorphic loci previously reported from Entamoeba histolytica have been detected in Entamoeba dispar. Comparison of nucleotide sequences of two loci between E. dispar strain SAW760 and E. histolytica strain HM-1:IMSS revealed significant differences in both repeat and flanking regions. The tandem repeat units varied not only in sequence but also in number and arrangement between the two species at both the loci. Using the sequences obtained, primer pairs aimed at amplifying species-specific products were designed and tested on a variety of E. histolytica and E. dispar samples. Amplification results were in complete agreement with the original species classification in all cases, and the PCR products displayed discernible size and pattern variations among the isolates.

Understanding ethnic/racial health disparities in youth and families in the US.

To summarize, ethnic and social class disparities are evident across a spectrum of markers of psychological, behavioral, and physical health. Furthermore, the pattern is often complex such that disparities are sometimes found within ethnic/racial groups as well as across those groups. Indeed, it is likely that the causes of health disparities may be different across specific subgroups. Moreover, theoretical models are needed that examine biological, contextual, and person-level variables (including culture-specific variables) to account for health disparities. The scholars in the present volume provide exemplary research that moves us towards more comprehensive and integrative models of health disparities. A brief glance at the work summarized by these scholars yields some common elements of focus for future researchers regarding risk (e.g., poverty, lack of contextual diversity) and protective (e.g., family support, cultural identity) factors yet they also identify aspects (e.g., genetic vulnerabilities) that may be unique to specific ethnic/racial groups. In addition to employing more integrative and culturally sensitive models of health disparities, future research studies could expand the scope of investigation to include transnational studies of health disparities and the processes contributing to them. They might also consider culture-specific health problems and syndromes such as "nervios" in Latino cultures. Within nations, further attention might be directed to the community contexts in which ethnic minority and low SES families reside, not only urban areas but the much less studied rural areas. Finally, efforts to assess health disparities and the factors contributing to them across cultural and ethnic groups need to attend closely to the issue of measurement equivalence in order to ensure valid cross-group comparisons. We would add that future research on health disparities will need to examine markers of positive health outcomes and well being (e

There are great disparities in mental health care around the world. Traditional approaches to mental health care have not been found to be transferrable to many parts of the world and are inadequate to address these disparities. Unconventional approaches are needed that match the traditions of care-seeking and care-giving within the communities where they are delivered. The authors review the global mental health literature and discuss how marriage and family therapists are in a particularly good position to have worldwide impact on mental health disparities. Five principles of global mental health are presented along with an example of how these principles are applied through the Reducing Mental Health Disparities One Community at a Time (RD1CT) model. © 2016 American Association for Marriage and Family Therapy.

Although health disparities research has already contributed to decreased mortality and morbidity in underserved communities, more work is needed. The NYC Epi Scholars program of the New York City Department of Health and Mental Hygiene (NYC DOHMH) aims to address gaps in critical public health needs and to train future public health leaders in epidemiology. The program is designed to increase racial/ethnic and socioeconomic diversity in the public health workforce, to provide fieldwork and practica opportunities, and to cultivate future leaders in epidemiology and public health. Since its inception in 2007, the NYC Epi Scholars program of the NYC DOHMH has sought talented epidemiology students interested in gaining practical experience in applied health disparities research. NYC Epi Scholars is open to graduate epidemiology students who have demonstrated achievement and leadership potential and gives them an opportunity to provide high-quality research assistance to projects that identify and address health disparities of public health significance. Many of the program's 32 alumni have made notable contributions to public health: publishing articles in peer-reviewed journals; making presentations at national and international conferences; and after graduating, pursuing careers at the DOHMH, Centers for Disease Control and Prevention, the Environmental Protection Agency, and the National Institutes of Health. Because of its noted success, the NYC Epi Scholars program may serve as a "best-practice" model for expansion in other urban health departments.

What makes African American health disparities newsworthy? An experiment among journalists about story framing.

PubMed

Hinnant, Amanda; Oh, Hyun Jee; Caburnay, Charlene A; Kreuter, Matthew W

2011-12-01

News stories reporting race-specific health information commonly emphasize disparities between racial groups. But recent research suggests this focus on disparities has unintended effects on African American audiences, generating negative emotions and less interest in preventive behaviors (Nicholson RA, Kreuter MW, Lapka C et al. Unintended effects of emphasizing disparities in cancer communication to African-Americans. Cancer Epidemiol Biomarkers Prev 2008; 17: 2946-52). They found that black adults are more interested in cancer screening after reading about the progress African Americans have made in fighting cancer than after reading stories emphasizing disparities between blacks and whites. This study builds on past findings by (i) examining how health journalists judge the newsworthiness of stories that report race-specific health information by emphasizing disparities versus progress and (ii) determining whether these judgments can be changed by informing journalists of audience reactions to disparity versus progress framing. In a double-blind-randomized experiment, 175 health journalists read either a disparity- or progress-framed story on colon cancer, preceded by either an inoculation about audience effects of such framing or an unrelated (i.e. control) information stimuli. Journalists rated the disparity-frame story more favorably than the progress-frame story in every category of news values. However, the inoculation significantly increased positive reactions to the progress-frame story. Informing journalists of audience reactions to race-specific health information could influence how health news stories are framed.

News stories reporting race-specific health information commonly emphasize disparities between racial groups. But recent research suggests this focus on disparities has unintended effects on African American audiences, generating negative emotions and less interest in preventive behaviors (Nicholson RA, Kreuter MW, Lapka C et al. Unintended effects of emphasizing disparities in cancer communication to African-Americans. Cancer Epidemiol Biomarkers Prev 2008; 17: 2946–52). They found that black adults are more interested in cancer screening after reading about the progress African Americans have made in fighting cancer than after reading stories emphasizing disparities between blacks and whites. This study builds on past findings by (i) examining how health journalists judge the newsworthiness of stories that report race-specific health information by emphasizing disparities versus progress and (ii) determining whether these judgments can be changed by informing journalists of audience reactions to disparity versus progress framing. In a double-blind-randomized experiment, 175 health journalists read either a disparity- or progress-framed story on colon cancer, preceded by either an inoculation about audience effects of such framing or an unrelated (i.e. control) information stimuli. Journalists rated the disparity-frame story more favorably than the progress-frame story in every category of news values. However, the inoculation significantly increased positive reactions to the progress-frame story. Informing journalists of audience reactions to race-specific health information could influence how health news stories are framed. PMID:21911844

Decoding conjunctions of direction-of-motion and binocular disparity from human visual cortex.

Motion and binocular disparity are two features in our environment that share a common correspondence problem. Decades of psychophysical research dedicated to understanding stereopsis suggest that these features interact early in human visual processing to disambiguate depth. Single-unit recordings in the monkey also provide evidence for the joint encoding of motion and disparity across much of the dorsal visual stream. Here, we used functional MRI and multivariate pattern analysis to examine where in the human brain conjunctions of motion and disparity are encoded. Subjects sequentially viewed two stimuli that could be distinguished only by their conjunctions of motion and disparity. Specifically, each stimulus contained the same feature information (leftward and rightward motion and crossed and uncrossed disparity) but differed exclusively in the way these features were paired. Our results revealed that a linear classifier could accurately decode which stimulus a subject was viewing based on voxel activation patterns throughout the dorsal visual areas and as early as V2. This decoding success was conditional on some voxels being individually sensitive to the unique conjunctions comprising each stimulus, thus a classifier could not rely on independent information about motion and binocular disparity to distinguish these conjunctions. This study expands on evidence that disparity and motion interact at many levels of human visual processing, particularly within the dorsal stream. It also lends support to the idea that stereopsis is subserved by early mechanisms also tuned to direction of motion.

Prior studies have described racial disparities in the quality of care for persons with HIV infection, but it is unknown if these disparities extend to common comorbid conditions. To inform implementation of interventions to reduce disparities in HIV care, we examined racial variation in a set of quality measures for common comorbid conditions among Veterans in care for HIV in the United States. The cohort included 23,974 Veterans in care for HIV in 2013 (53.4% black; 46.6% white). Measures extracted from electronic health record and administrative data were receipt of combination antiretroviral therapy (cART), HIV viral control (serum RNA < 200 copies/ml among those on cART), hypertension control (blood pressure < 140/90 mm Hg among those with hypertension), diabetes control (hemoglobin A1C < 9% among those with diabetes), lipid monitoring, guideline-concordant antidepressant prescribing, and initiation and engagement in substance use disorder (SUD) treatment. Black persons were less likely than their white counterparts to receive cART (90.2% vs. 93.2%, p<.001), and experience viral control (84.6% vs. 91.3%, p<.001), hypertension control (61.9% vs. 68.3%, p<.001), diabetes control (85.5% vs. 89.5%, p<.001), and lipid monitoring (81.5% vs. 85.2%, p<.001). Initiation and engagement in SUD treatment were similar among blacks and whites. Differences remained after adjusting for age, comorbidity, retention in HIV care, and a measure of neighborhood social disadvantage created from census data. Implementation of interventions to reduce racial disparities in HIV care should comprehensively address and monitor processes and outcomes of care for key comorbidities. Published by Elsevier Inc.

Racial disparities in the burden of sexually transmitted diseases (STDs) have been documented and described for decades. Similarly, methodological issues and limitations in the use of disparity measures to quantify disparities in health have also been well documented. The purpose of this study was to use historic STD surveillance data to illustrate four of the most well-known methodological issues associated with the use of disparity measures. We manually searched STD surveillance reports to find examples of racial/ethnic distributions of reported STDs that illustrate key methodological issues in the use of disparity measures. The disparity measures we calculated included the black-white rate ratio, the Index of Disparity (weighted and unweighted by subgroup population), and the Gini coefficient. The 4 examples we developed included illustrations of potential differences in relative and absolute disparity measures, potential differences in weighted and nonweighted disparity measures, the importance of the reference point when calculating disparities, and differences in disparity measures in the assessment of trends in disparities over time. For example, the gonorrhea rate increased for all minority groups (relative to whites) from 1992 to 1993, yet the Index of Disparity suggested that racial/ethnic disparities had decreased. Although imperfect, disparity measures can be useful to quantify racial/ethnic disparities in STDs, to assess trends in these disparities, and to inform interventions to reduce these disparities. Our study uses reported STD rates to illustrate potential methodological issues with these disparity measures and highlights key considerations when selecting disparity measures for quantifying disparities in STDs.

The Role of Worldviews in Health Disparities Education

PubMed Central

2010-01-01

Worldviews are sets of beliefs and assumptions that express how cultures interpret and explain their experience. Worldview has been a useful explanatory construct in the social science literature, but has been used less often in the context of human health. Reducing and ultimately eliminating the negative role that health care providers play in producing health disparities will require a cultural change. Here I posit that “worldview” is a critically important concept for health disparities education that overtime will serve to transform the culture of health care professionals toward a more self-reflective, humble, and open-minded posture.

2018-02-01

To examine wellness programs with financial incentives and their effect on disparities in preventive care. Financial incentives were introduced by 15 large employers, from 2010 to 2013. Fifteen private employers. A total of 299 436 employees and adult dependents. Preventive services and participation in financial incentives. Multivariate linear regression. Disparities in preventive services widened after introduction of financial incentives. Asians were 3% more likely and African Americans were 3% less likely to receive wellness rewards than whites and non-Hispanics, controlling for other factors. Federal law limits targeting of wellness financial incentives by subgroups; thus, employers should consider outreach and culturally appropriate messaging.

Neighborhoods and Race/Ethnic Disparities in Adolescent Sexual Risk Behavior

2013-01-01

Understanding the determinants of racial/ethnic disparities in adolescent sexual risk behavior is important given its links to the differential risk of teen pregnancy, childbearing, and sexually transmitted infections. This article tests a contextual model that emphasizes the concentration of neighborhood disadvantage in shaping racial/ethnic disparities in sexual risk behavior. We focus on two risk behaviors that are prevalent among Black and Hispanic youth: the initiation of sexual activity in adolescence and the number of sex partners. Using data from the 1997 National Longitudinal Study of Youth (N = 6,985; 48% female; 57% non-Hispanic White) evidence indicates that neighborhood disadvantage – measured by concentrated poverty, unemployment rates, and the proportion of female-headed households – partially explains Black and Hispanic disparities from Whites in the odds of adolescent sexual debut, although the prevalence of female-headed households in neighborhoods appears to be the main driver in this domain. Likewise, accounting for neighborhood disadvantage reduces the Black-White and Hispanic-White disparity in the number of sexual partners, although less so relative to sexual debut. We discuss theoretical and practical implications of these findings. PMID:24214727

Addressing the Social Determinants of Health to Reduce Tobacco-Related Disparities.

2015-08-01

Comprehensive tobacco prevention and control efforts that include implementing smoke-free air laws, increasing tobacco prices, conducting hard-hitting mass media campaigns, and making evidence-based cessation treatments available are effective in reducing tobacco use in the general population. However, if these interventions are not implemented in an equitable manner, certain population groups may be left out causing or exacerbating disparities in tobacco use. Disparities in tobacco use have, in part, stemmed from inequities in the way tobacco control policies and programs have been adopted and implemented to reach and impact the most vulnerable segments of the population that have the highest rates of smokings (e.g., those with lower education and incomes). Education and income are the 2 main social determinants of health that negatively impact health. However, there are other social determinants of health that must be considered for tobacco control policies to be effective in reducing tobacco-related disparities. This article will provide an overview of how tobacco control policies and programs can address key social determinants of health in order to achieve equity and eliminate disparities in tobacco prevention and control. Tobacco control policy interventions can be effective in addressing the social determinants of health in tobacco prevention and control to achieve equity and eliminate tobacco-related disparities when they are implemented consistently and equitably across all population groups. Taking a social determinants of health approach in tobacco prevention and control will be necessary to achieve equity and eliminate tobacco-related disparities. © The Author 2014.

Anti-bullying Policies and Disparities in Bullying: A State-Level Analysis.

PubMed

Hatzenbuehler, Mark L; Flores, Javier E; Cavanaugh, Joseph E; Onwuachi-Willig, Angela; Ramirez, Marizen R

2017-08-01

Recent research suggests that anti-bullying laws may be effective in reducing risk of bullying victimization among youth, but no research has determined whether these laws are also effective in reducing disparities in bullying. The aim of this paper was to evaluate the effectiveness of anti-bullying legislation in reducing disparities in sex- and weight-based bullying and cyberbullying victimization. Data on anti-bullying legislation were obtained from the U.S. Department of Education, which commissioned a systematic review of 16 key components of state laws in 2011. States were also categorized based on whether their legislation enumerated protected groups and, if so, which groups were enumerated. These policy variables from 28 states were linked to individual-level data on bullying and cyberbullying victimization from students in 9th through 12th grade participating in the 2011 Youth Risk Behavior Surveillance System study (N=79,577). Analyses were conducted in 2016. There was an absence of any kind of moderating effect of anti-bullying legislation on weight-based disparities in bullying and cyberbullying victimization. Only state laws with high compliance to Department of Education enumeration guidelines were associated with lower sex-based disparities in bullying victimization. Anti-bullying policies were not associated with lower weight-based disparities in bullying and cyberbullying victimization among youth, and only one form of policies (high compliance to Department of Education enumeration guidelines) was associated with lower sex-based disparities in bullying victimization. Results therefore suggest that anti-bullying legislation requires further refinement to protect youth who are vulnerable to bullying victimization.

To describe the dynamics of trends in socioeconomic disparities in oral health in Brazil and Sweden among adults, to assess whether trends follow expected patterns according to the inverse equity hypothesis. In Sweden, we obtained nationally representative data for the years 1968, 1974, 1981, 1991 and 2000, and in Brazil, for 16 state capitals in 1986 and in 2002. Trends in the prevalence of 'edentulism' and of 'teeth in good conditions' were described in two groups aged 35-44 with lower and higher economic standards, respectively. There was an annual decline in disparities in 'edentulism' of 0.4 percentage points (pp) (95% CI = 0.2-0.7) in Brazil and 0.7pp (95% CI = 0.5-0.9) in Sweden, as a result of improvements in both income groups. Concerning 'teeth in good conditions', in Brazil, there was improvement only in the higher income group and absolute disparities have increased (0.5pp annually), while in Sweden, there was a nonsignificant decrease (0.3pp annually) with improvements in both groups. Since 1991 in Sweden and in 2002 in Brazil, our measures of socioeconomic disparities in 'edentulism' were not statistically significant. Trends did not differ by sex or dental visit. Despite improvements in both income groups and a decrease in disparities in 'edentulism', the poorer group in Brazil has seen no improvement in 'teeth in good conditions' and disparities have increased. It appears that Brazil and Sweden reflect different stages of trend for 'teeth in good conditions' and the same stages for 'edentulism', represented by the inverse equity hypothesis. © 2010 John Wiley & Sons A/S.

Identification of racial disparities in breast cancer mortality: does scale matter?

PubMed Central

2010-01-01

Background This paper investigates the impact of geographic scale (census tract, zip code, and county) on the detection of disparities in breast cancer mortality among three ethnic groups in Texas (period 1995-2005). Racial disparities were quantified using both relative (RR) and absolute (RD) statistics that account for the population size and correct for unreliable rates typically observed for minority groups and smaller geographic units. Results were then correlated with socio-economic status measured by the percentage of habitants living below the poverty level. Results African-American and Hispanic women generally experience higher mortality than White non-Hispanics, and these differences are especially significant in the southeast metropolitan areas and southwest border of Texas. The proportion and location of significant racial disparities however changed depending on the type of statistic (RR versus RD) and the geographic level. The largest proportion of significant results was observed for the RD statistic and census tract data. Geographic regions with significant racial disparities for African-Americans and Hispanics frequently had a poverty rate above 10.00%. Conclusions This study investigates both relative and absolute racial disparities in breast cancer mortality between White non-Hispanic and African-American/Hispanic women at the census tract, zip code and county levels. Analysis at the census tract level generally led to a larger proportion of geographical units experiencing significantly higher mortality rates for minority groups, although results varied depending on the use of the relative versus absolute statistics. Additional research is needed before general conclusions can be formulated regarding the choice of optimal geographic regions for the detection of racial disparities. PMID:20602784

2008-01-01

Evidence shows that disparities in pain care exist, and this problem spans across all health care settings. Health care disparities are complex, and stem from the health system climate, limitations imposed by laws and regulations, and discriminatory practices that are deep seated in biases, stereotypes, and uncertainties surrounding communication and decision-making processes. A search of the Internet identified thousands of Web sites, documents, reports, and educational materials pertaining to health and pain disparities. Web sites for federal agencies, private foundations, and professional and consumer-oriented organizations provide useful information on disparities related to age, race, ethnicity, geography, socioeconomic status, and specific populations. The contents of 10 Web sites are examined for resources to assist health professionals and consumers in better understanding health and pain disparities and ways to overcome them in practice.

Service learning (SL) is a form of community-centered experiential education that places emerging health professionals in community-generated service projects and provides structured opportunities for reflection on the broader social, economic, and political contexts of health. We describe the elements and impact of five distinct week-long intensive SL courses focused on the context of urban, rural, border, and indigenous health contexts. Students involved in these SL courses demonstrated a commitment to community-engaged scholarship and practice in both their student and professional lives. SL is directly in line with the core public health value of social justice and serves as a venue to strengthen community–campus partnerships in addressing health disparities through sustained collaboration and action in vulnerable communities.

Winner-take-all phenomena are observed in various competitive systems. We find similar phenomena in replicator models with randomly fluctuating growth rates. The disparity between winners and losers increases indefinitely, even if all elements are statistically equivalent. A lognormal distribution describes well the nonstationary time evolution. If a nonlinear load corresponding to progressive taxation is introduced, a stationary distribution is obtained and disparity widening is suppressed.

LGBT older adults are a heterogeneous population with collective and unique strengths and challenges. Health, personal, and economic disparities exist in this group when compared to the general population of older adults, yet subgroups such as transgender and bisexual older adults and individuals living with HIV are at greater risk for disparities and poorer health outcomes. As this population grows, further research is needed on factors that contribute to promoting health equity, while decreasing discrimination and improving competent service delivery.

Pediatric appendicitis rupture rate: a national indicator of disparities in healthcare access.

PubMed

Jablonski, Kathleen A; Guagliardo, Mark F

2005-05-04

BACKGROUND: The U.S. National Healthcare Disparities Report is a recent effort to measure and monitor racial and ethnic disparities in health and healthcare. The Report is a work in progress and includes few indicators specific to children. An indicator worthy of consideration is racial/ethnic differences in the rate of bad outcomes for pediatric acute appendicitis. Bad outcomes for this condition are indicative of poor access to healthcare, which is amenable to social and healthcare policy changes. METHODS: We analyzed the KID Inpatient Database, a nationally representative sample of pediatric hospitalization, to compare rates of appendicitis rupture between white, African American, Hispanic and Asian children. We ran weighted logistic regression models to obtain national estimates of relative odds of rupture rate for the four groups, adjusted for developmental, biological, socioeconomic, health services and hospital factors that might influence disease outcome. RESULTS: Rupture was a much more burdensome outcome than timely surgery and rupture avoidance. Rupture cases had 97% higher hospital charges and 175% longer hospital stays than non-rupture cases on average. These burdens disproportionately affected minority children, who had 24% - 38% higher odds of appendicitis rupture than white children, adjusting for age and gender. These differences were reduced, but remained significant after adjusting for other factors. CONCLUSION: The racial/ethnic disparities in pediatric appendicitis outcome are large and are preventable with timely diagnosis and surgery for all children. Furthermore, estimating this disparity using the KID survey is a relatively straightforward process. Therefore pediatric appendicitis rupture rate is a good candidate for inclusion in the National Healthcare Disparities Report. As with most other health and healthcare disparities, efforts to reduce disparities in income, wealth and access to care will most likely improve the odds of favorable

Is there progress toward eliminating racial/ethnic disparities in the leading causes of death?

Keppel, Kenneth G; Pearcy, Jeffrey N; Heron, Melonie P

2010-01-01

We examined changes in relative disparities between racial/ethnic populations for the five leading causes of death in the United States from 1990 to 2006. The study was based on age-adjusted death rates for four racial/ethnic populations from 1990-1998 and 1999-2006. We compared the percent change in death rates over time between racial/ethnic populations to assess changes in relative differences. We also computed an index of disparity to assess changes in disparities relative to the most favorable group rate. Except for stroke deaths from 1990 to 1998, relative disparities among racial/ethnic populations did not decline between 1990 and 2006. Disparities among racial/ethnic populations increased for heart disease deaths from 1999 to 2006, for chronic obstructive pulmonary disease deaths from 1990 to 1998, and for chronic lower respiratory disease deaths from 1999 to 2006. Deaths rates for the leading causes of death are generally declining; however, relative differences between racial/ethnic groups are not declining. The lack of reduction in relative differences indicates that little progress is being made toward the elimination of racial/ethnic disparities.

Racial and Ethnic Health Disparities in Reproductive Medicine: An Evidence-Based Overview

PubMed Central

Owen, Carter M.; Goldstein, Ellen H.; Clayton, Janine A.; Segars, James H.

2014-01-01

Racial and ethnic health disparities in reproductive medicine exist across the life span and are costly and burdensome to our healthcare system. Reduction and ultimate elimination of health disparities is a priority of the National Institutes of Health who requires reporting of race and ethnicity for all clinical research it supports. Given the increasing rates of admixture in our population, the definition and subsequent genetic significance of self-reported race and ethnicity used in health disparity research is not straightforward. Some groups have advocated using self-reported ancestry or carefully selected single-nucleotide polymorphisms, also known as ancestry informative markers, to sort individuals into populations. Despite the limitations in our current definitions of race and ethnicity in research, there are several clear examples of health inequalities in reproductive medicine extending from puberty and infertility to obstetric outcomes. We acknowledge that socioeconomic status, education, insurance status, and overall access to care likely contribute to the differences, but these factors do not fully explain the disparities. Epigenetics may provide the biologic link between these environmental factors and the transgenerational disparities that are observed. We propose an integrated view of health disparities across the life span and generations focusing on the metabolic aspects of fetal programming and the effects of environmental exposures. Interventions aimed at improving nutrition and minimizing adverse environmental exposures may act synergistically to reverse the effects of these epigenetic marks and improve the outcome of our future generations.

2017-01-01

This study aims to investigate health disparities between lesbian, gay, and bisexual (LGB) adults and the general population in Korea, where there is low public acceptance of sexual minorities and a lack of research on the health of sexual minorities. The research team conducted a nationwide survey of 2,335 Korean LGB adults in 2016. Using the dataset, we estimated the age-standardized prevalence ratios (SPRs) for poor self-rated health, musculoskeletal pain, depressive symptoms, suicidal behaviors, smoking, and hazardous drinking. We then compared the SPRs of the LGB adults and the general population which participated in three different nationally representative surveys in Korea. SPRs were estimated for each of the four groups (i.e., gay men, bisexual men, lesbians, and bisexual women). Korean LGB adults exhibited a statistically significantly higher prevalence of depressive symptoms, suicidal ideation and attempts, and musculoskeletal pain than the general population. Lesbian and bisexual women had a higher risk of poor self-rated health and smoking than the general women population, whereas gay and bisexual men showed no differences with the general men population. Higher prevalence of hazardous drinking was observed among lesbians, gay men, and bisexual women compared to the general population, but was not observed in bisexual men. The findings suggest that LGB adults have poorer health conditions compared to the general population in Korea. These results suggest that interventions are needed to address the health disparities of Korean LGB adults.

Since 1887, the Policlinique Médicale Universitaire (PMU) has brought care to vulnerable populations who are at risk of poor physical, mental and social health. These include marginalised Swiss natives and immigrant communities (asylum seekers, undocumented immigrants). These patients are at risk of health disparities given their poor access to the health care system and lack of adapted quality care. Clinical approach must address these potential disparities, reinforced by a research describing them in order to explain their cause, and propose possible solutions, and a medical training addressing these topics from the undergraduate to the attending level. Through those holistic clinical approach, robust research and improved medical training, health providers will contribute to give quality care to all citizens, without exception!

To determine whether there is an Appalachian disparity in caries prevalence or extent in children living in Pennsylvania. We conducted a cross-sectional clinical assessment of caries in a sample representing 1st, 3rd, 9th, and 11th grade students across Pennsylvania. We used logistic regression and zero-inflated negative binomial regression controlling for age to examine the association of residence in an Appalachian county with caries prevalence and extent in the primary and permanent dentitions. Compared with children living outside Appalachia, more children living in Appalachia had a dft >0 (OR = 1.37, 95% CI = 1.07-1.76) and more had a DMFT >0 (OR = 1.32, 95% CI = 1.06-1.64). In addition, compared with children living outside Appalachia, children living in Appalachia had a greater primary but not permanent caries extent (IRR = 1.10, 95% CI = 1.01-1.19). We found Appalachian disparities in caries prevalence in both the primary and permanent dentitions and an Appalachian disparity in caries extent in the primary dentition. None of the disparities was moderated by age. This suggests that the search for the mechanism or mechanisms for the Appalachian disparities should focus on differential exposures to risk factors occurring prior to and at the start of elementary school. © 2014 John Wiley & Sons A/S.

Rienks, Jennifer; Oliva, Geraldine

2013-05-01

African American infants in San Francisco suffer a mortality rate two to three times higher than Whites, yet prior discussion groups with African American residents suggested they were unaware of this disparity. Social marketing techniques were used to develop and implement three campaigns to increase awareness. The campaign themes were (1) infant mortality disparities, (2) proper infant sleep position, and (3) taking action to reduce disparities. Mediums to carry messages included bus ads, radio ads, church fans, and posters and cards distributed at clinics, daycares, agency waiting rooms, and community organizations. Campaign effectiveness was evaluated using telephone surveys of African Americans. Almost 62% report some exposure to Campaign 1, 48.5% to Campaign 2, and 48.9% to Campaign 3. Chi-square analyses reveal a statistically ignificant increase in awareness of the disparity (39.6% vs. 62.7%, p < .0005, odds ratio [OR] = 2.5, confidence interval [CI] = 2.1-3.2). Although there was no overall significant increase in knowledge about proper sleep position, respondents who report any exposure to this campaign are more likely to know about sleep position (70.7% vs. 63.8%, p < .0001, OR = 2.2, CI = 1.6-3.2). Social marketing is an effective tool to increase disparity awareness, especially among groups disproportionately affected by the disparity.

Rural-urban disparities in child nutrition in Bangladesh and Nepal

2013-01-01

Background The persistence of rural-urban disparities in child nutrition outcomes in developing countries alongside rapid urbanisation and increasing incidence of child malnutrition in urban areas raises an important health policy question - whether fundamentally different nutrition policies and interventions are required in rural and urban areas. Addressing this question requires an enhanced understanding of the main drivers of rural-urban disparities in child nutrition outcomes especially for the vulnerable segments of the population. This study applies recently developed statistical methods to quantify the contribution of different socio-economic determinants to rural-urban differences in child nutrition outcomes in two South Asian countries – Bangladesh and Nepal. Methods Using DHS data sets for Bangladesh and Nepal, we apply quantile regression-based counterfactual decomposition methods to quantify the contribution of (1) the differences in levels of socio-economic determinants (covariate effects) and (2) the differences in the strength of association between socio-economic determinants and child nutrition outcomes (co-efficient effects) to the observed rural-urban disparities in child HAZ scores. The methodology employed in the study allows the covariate and coefficient effects to vary across entire distribution of child nutrition outcomes. This is particularly useful in providing specific insights into factors influencing rural-urban disparities at the lower tails of child HAZ score distributions. It also helps assess the importance of individual determinants and how they vary across the distribution of HAZ scores. Results There are no fundamental differences in the characteristics that determine child nutrition outcomes in urban and rural areas.

Cardiovascular disease (CVD), which includes coronary artery disease and stroke, is the leading cause of mortality in the nation. Excess CVD morbidity and premature mortality in the African American community is one of the most striking examples of racial/ethnic disparities in health outcomes. African Americans also suffer from increased rates of hypovitaminosis D, which has emerged as an independent risk factor for all-cause and cardiovascular mortality. This overview examines the potential role of hypovitaminosis D as a contributor to racial and ethnic disparities in cardiovascular disease (CVD). We review the epidemiology of vitamin D and CVD in African Americans and the emerging biological roles of vitamin D in key CVD signaling pathways that may contribute to the epidemiological findings and provide the foundation for future therapeutic strategies for reducing health disparities.

The impact of predictive genetic testing on cancer care can be measured by the increased demand for and utilization of genetic services as well as in the progress made in reducing cancer risks in known mutation carriers. Nonetheless, differential access to and utilization of genetic counseling and cancer predisposition testing among underserved racial and ethnic minorities compared with the white population has led to growing health care disparities in clinical cancer genetics that are only beginning to be addressed. Furthermore, deficiencies in the utility of genetic testing in underserved populations as a result of limited testing experience and in the effectiveness of risk-reducing interventions compound access and knowledge-base disparities. The recent literature on racial/ethnic health care disparities is briefly reviewed, and is followed by a discussion of the current limitations of risk assessment and genetic testing outside of white populations. The importance of expanded testing in underserved populations is emphasized.

Depressive symptom disparity between urban and rural older adults is an important public health issue in China. Social support is considered as an effective way to alleviate depression of older adults. This study aimed to investigate the extent to which social support could explain the depressive symptom disparity between urban and rural older adults in China. This study used data drawn from the 2011 China Health and Retirement Longitudinal Study with 6,772 observations. Multiple data analysis strategies were adopted, including descriptive analyses, bivariate analyses, regression analyses and decomposition analyses. There were significant depressive symptom disparities between urban and rural older adults in China. Social support had significant association with depressive symptom of older adults while adjusting for covariates. About 25%-28% of the depressive symptom disparities could be attributed to urban-rural gaps in social support, in which community support contributed 21%-25%. Educational level and physical health status also contributed to the disparities. This study only established correlations between social support and depressive symptom disparity rather than casual relationships; and the self-reported measurement of depressive symptom and the unobservable cultural factors might cause limitations. The urban-rural gap in social support, especially community support was a prime explanation for depressive symptom disparities between urban and rural older adults in China. To reduce the depressive symptom disparities, effective community construction in rural China should be put into place, including improving the infrastructure construction, strengthening the role of social organizations, and encouraging community interpersonal interactions for older adults.

Introduction Racial disparities in obesity exist at the individual and community levels. Retail food environment has been hypothesized to be associated with racial disparities in obesity prevalence. This study aimed to quantify how much food environment measures explain racial disparities in obesity at the county level. Methods Data from 2009 to 2010 on 3,135 U.S. counties were extracted from the U.S. Department of Agriculture Food Environment Atlas and the Behavioral Risk Factor Surveillance System and analyzed in 2013. Oaxaca–Blinder decomposition was used to quantify the portion of the gap in adult obesity prevalence observed between counties with a high and low proportion of African American residents is explained by food environment measures (e.g., proximity to grocery stores, per capita fast food restaurants). Counties were considered to have a high African American population if the percentage of African American residents was >13.1%, which represents the 2010 U.S. Census national estimate of percentage African American citizens. Results There were 665 counties (21%) classified as a high African American county. The total gap in mean adult obesity prevalence between high and low African American counties was found to be 3.35 percentage points (32.98% vs 29.63%). Retail food environment measures explained 13.81% of the gap in mean age-adjusted adult obesity prevalence. Conclusions Retail food environment explains a proportion of the gap in adult obesity prevalence observed between counties with a high proportion of African American residents and counties with a low proportion of African American residents.

Large and persistent racial/ethnic disparities exist in diabetes care. Considering the rapid rate of growth of Medicare Managed Care (MMC) plans among minority populations, our aim was to investigate whether disparities in diabetes management and healthcare expenditures are smaller in MMC versus Medicare fee-for-service (MFFS) plans. We hypothesized that racial/ethnic disparities in diabetes care and in health expenditures would be less pronounced in MMC compared with MFFS plans. Nationally representative data from the 2006 to 2011 Medical Expenditure Panel Survey on white, African American, and Hispanic seniors with diabetes were analyzed. We examined 4 measures of diabetes care-regular foot check, eye exam, cholesterol check, and flu vaccine-and total and out-of-pocket (OOP) healthcare expenditures. We implemented the Institute of Medicine's definition of disparity, applied propensity score weighting to adjust for potential differential selection, and used a difference-in-differences generalized linear framework to estimate outcome measures. For African Americans, MMC was associated with a $1183 (P <.036) reduction and a $547 (P <.001) increase in disparities in total and OOP healthcare expenditures, respectively. For Hispanics, disparities in foot exam, flu shot, and cholesterol check decreased by 5, 10, and 7 percentage points (P <.001); additionally, disparities in total and OOP healthcare expenditures were reduced by $3588 and $276 (P <.001), respectively. MMC plans spend less on everyone, including whites. Hispanic/white disparities in diabetes management and healthcare expenditures were smaller in MMC than in MFFS plans. African American/white disparities were not consistently larger in 1 setting than the other.

Socioeconomic Dynamics of Gender Disparity in Childhood Immunization in India, 1992–2006

Background Recent evidence indicated that gender disparity in child health is minimal and narrowed over time in India. However, considering the geographical and socio-cultural diversity in India, the gender gap may persist across disaggregated socioeconomic context which may be masked by average level. This study examines the dynamics of gender disparity in childhood immunization across regions, residence, wealth, caste and religion in India during 1992–2006. Method We used multi-waves of the cross-sectional data of National Family Health Survey conducted in India between 1992–93 and 2005–06. Gender disparity ratio was used to measure the gender gap in childhood immunization across the selected socioeconomic characteristics. Multinomial regression analysis was used to examine the gender gap after accounting for other covariates. Result Results indicate that, at aggregate level, gender disparity in full immunization is minimal and has stagnated during the study period. However, gender disparity – disfavouring female children – becomes apparent across the regions, poor households, and religion - particularly among Muslims. Adjusted gender disparity ratio indicates that, full immunization is lower among female than male children of the western region, poor household and among Muslims. Between 1992–93 and 2005–06, the disparity in full immunization had narrowed in the northern region whereas it had, astonishingly, increased in some of the western and southern states of the country. Conclusion Our findings emphasize the need to integrate gender issues in the ongoing immunization programme in India, with particular attention to urban areas, developed states, and to the Muslim community.

Introduction Racial and ethnic minorities have disproportionately higher cancer incidence and mortality than their White counterparts. In response to this inequity in cancer prevention and care, community-based lay health advisors (LHAs) may be suited to deliver effective, culturally relevant, quality cancer education, prevention/screening, and early detection services for underserved populations. Approach and Strategies Consistent with key tenets of community-based participatory research (CBPR), this project engaged community partners to develop and implement a unique LHA training curriculum to address cancer health disparities among medically underserved communities in a tricounty area. Seven phases of curriculum development went into designing a final seven-module LHA curriculum. In keeping with principles of CBPR and community engagement, academic–community partners and LHAs themselves were involved at all phases to ensure the needs of academic and community partners were mutually addressed in development and implementation of the LHA program. Discussion and Conclusions Community-based LHA programs for outreach, education, and promotion of cancer screening and early detection, are ideal for addressing cancer health disparities in access and quality care. When community-based LHAs are appropriately recruited, trained, and located in communities, they provide unique opportunities to link, bridge, and facilitate quality cancer education, services, and research.

There are documented disparities in the rates at which black children come into contact with the child welfare system in the United States compared to white children. A great deal of research has proliferated aimed at understanding whether systematic biases or differential rates of risk among different groups drive these disparities (Drake et al., 2011). In the current study, county rates of maltreatment disparity are compared across the United States and examined in relation to rates of poverty disparity as well as population density. Specifically, using hierarchical linear modeling with a spatially lagged dependent variable, the current study examined data from the National Child Abuse and Neglect Data System (NCANDS) and found that poverty disparities were associated with rates of maltreatment disparities, and densely populated metropolitan counties tended to have the greatest levels of maltreatment disparity for both black and Hispanic children. A significant curvilinear relationship was also observed between these variables, such that in addition to the most densely populated counties, the most sparsely populated counties also tended to have higher rates of maltreatment disparity for black and Hispanic children.

Simpson, Sean L.; Hairston, Kristen G.

2011-01-01

Objectives. We created an index quantifying the longitudinal burden of racial health disparities by state and compared this index to variables to guide the construction of, and validate support for, legislative efforts aimed at eliminating health disparities. Methods. We evaluated 5 focus areas of greatest racial disparities in health from 1999 to 2005 and compiled state health disparities index (HDI) scores. We compared these scores with variables representing the purported social determinants of health. Results. Massachusetts (0.35), Oklahoma (0.35), and Washington (0.39) averaged the fewest disparities. Michigan (1.22), Wisconsin (1.32), and Illinois (1.50) averaged the greatest disparities. The statistical reference point for nationwide average racial disparities was 1.00. The longitudinal mixed model procedure yielded statistically significant correlations between HDI scores and Black state population percentage as well as with the racial gap in uninsured percentages. We noted a trend for HDI correlations with median household income ratios. Conclusions. On the basis of the HDI-established trends in the extent and distribution of racial health disparities, and their correlated social determinants of health, policymakers should consider incorporating this tool to advise future efforts in minority health legislation.

Child Health Disparities: What Can a Clinician Do?

Pediatric primary and specialty practice has changed, with more to do, more regulation, and more family needs than in the past. Similarly, the needs of patients have changed, with more demographic diversity, family stress, and continued health disparities by race, ethnicity, and socioeconomic status. How can clinicians continue their dedicated service to children and ensure health equity in the face of these changes? This article outlines specific, practical, actionable, and evidence-based activities to help clinicians assess and address health disparities in practice. These tools may also support patient-centered medical home recognition, national and state cultural and linguistic competency standards, and quality benchmarks that are increasingly tied to payment. Clinicians can play a critical role in (1) diagnosing disparities in one's community and practice, (2) innovating new models to address social determinants of health, (3) addressing health literacy of families, (4) ensuring cultural competence and a culture of workplace equity, and (5) advocating for issues that address the root causes of health disparities. Culturally competent care that is sensitive to the needs, health literacy, and health beliefs of families can increase satisfaction, improve quality of care, and increase patient safety. Clinical care approaches to address social determinants of health and interrupting the intergenerational cycle of disadvantage include (1) screening for new health "vital signs" and connecting families to resources, (2) enhancing the comprehensiveness of services, (3) addressing family health in pediatric encounters, and (4) moving care outside the office into the community. Health system investment is required to support clinicians and practice innovation to ensure equity. Copyright © 2015 by the American Academy of Pediatrics.

Racial and ethnic disparities in the financial burden of prescription drugs among older Americans.

Xu, K Tom; Borders, Tyrone F

2007-01-01

This study examines racial and ethnic disparities in the financial burden of prescription drugs among older Americans using a market and an egalitarian model. A nationally representative data set, the Medical Expenditure Panel Survey 2002, was used. The financial burden of prescription drugs was measured by the out-of-pocket expenditure and proportion. In the market model (utilization adjustment)., utilization was measured at the annual aggregate level by the total number of prescription drugs, the average refills and the average quantity per prescription drug. In the egalitarian model (need adjustment)., health was measured by 15 chronic and costly diseases and the SF-12. Individuals 65 years or older were included. Nationally representative estimates were calculated. Raw racial and ethnic disparities were observed in the bivariate analyses between non-Hispanic whites and Hispanics in the out-of-pocket expenditure and proportion, and between non-Hispanic whites and non-Hispanic blacks in the out-of-pocket proportion. However, these disparities disappeared after controlling for utilization or health needs. Insurance status contributed the most to the disparities in the financial burden of prescription drugs. In conclusion, The disparities in the financial burden of prescription drugs between non-Hispanic elderly whites and Hispanics may be attributable to differences in utilization patterns. However, whether health disparities contribute to disparities in the financial burden of prescription drugs requires studies of specific diseases.

Background This study assesses racial/ethnic disparities in negative social consequences of drinking and alcohol dependence symptoms among white, black and Hispanic Americans. We examine whether and how disparities relate to heavy alcohol consumption and pattern, and the extent to which social disadvantage (poverty, unfair treatment, and racial/ethnic stigma) accounts for observed disparities. Methods We analyzed data from the 2005 U.S. National Alcohol Survey, an RDD telephone survey conducted with adults ages 18 and older in the 50 states and the District of Columbia (N=6,919). Given large racial/ethnic differences in abstinence rates, core analyses were restricted to current drinkers (N=4,080). Logistic regression was used to assess disparities in alcohol-related problems at three levels of heavy drinking, measured using a composite variable incorporating frequency of heavy episodic drinking, frequency of drunkenness, and maximum amount consumed in a single day. A mediational approach was used to assess the role of social disadvantage. Results African American and Hispanic drinkers were significantly more likely than white drinkers to report social consequences of drinking and alcohol dependence symptoms. Even after adjusting for differences in heavy drinking and demographic characteristics, disparities in problems remained. The racial/ethnic gap in alcohol problems was greatest among those reporting little or no heavy drinking, and gradually diminished to nonsignificance at the highest level of heavy drinking. Social disadvantage, particularly in the form of racial/ethnic stigma, appeared to contribute to racial/ethnic differences in problems. Conclusions These findings suggest that to eliminate racial/ethnic disparities in alcohol-related problems, public health efforts must do more than reduce heavy drinking. Future research should address the possibility of drink size underestimation, identify the particular types of problems that disproportionately affect

Global Gender Disparities in Obesity: A Review1

PubMed Central

Caballero, Benjamin

2012-01-01

There is a global obesity pandemic. However, the prevalence of overweight and obesity among men and women varies greatly within and between countries, and overall, more women are obese than men. These gender disparities in overweight and obesity are exacerbated among women in developing countries, particularly in the Middle East and North Africa. Yet, in developed countries, more men are overweight than women. Current knowledge suggests that myriad sociocultural dynamics throughout the world exacerbate gender disparities in excess weight gain. Different contextual factors drive gender differences in food consumption, and women often report consuming healthier foods, yet may consume more sugar-laden foods, than men. Acculturation, through complex sociocultural pathways, affects weight gain among both men and women. The nutrition transition taking place in many developing countries has also affected excess weight gain among both genders, but has had an even greater impact on the physical activity levels of women. Furthermore, in some countries, cultural values favor larger body size among women or men as a sign of fertility, healthfulness, or prosperity. As the global obesity pandemic continues, more research on gender disparities in overweight and obesity will improve the understanding of this pandemic. PMID:22797984

Objectives. To quantify the characteristics of community health workers (CHWs) involved in community intervention research and, in particular, to characterize their job titles, roles, and responsibilities; recruitment and compensation; and training and supervision. Methods. We developed and administered a structured questionnaire consisting of 25 closed- and open-ended questions to staff on National Institutes of Health–funded Centers for Population Health and Health Disparities projects between March and April 2014. We report frequency distributions for CHW roles, sought-after skills, education requirements, benefits and incentives offered, and supervision and training activities. Results. A total of 54 individuals worked as CHWs across the 18 research projects and held a diverse range of job titles. The CHWs commonly collaborated on research project implementation, provided education and support to study participants, and collected data. Training was offered across projects to bolster CHW capacity to assist in intervention and research activities. Conclusions. Our experience suggests national benefit in supporting greater efforts to recruit, retain, and support the work of CHWs in community-engagement research. PMID:26794157

Objective Despite overall improvements in congenital heart disease outcomes, racial and ethnic disparities have continued. The purpose of this study is to examine the effect of race and ethnicity, as well as other risk factors on congenital heart surgery length of stay and in-hospital mortality. Design From the 2012 Healthcare Cost and Utilization Project Kids Inpatient Database (KID), we identified 13,130 records with Risk Adjustment in Congenital Heart Surgery complexity score-eligible procedures. Multivariate logistic and linear regression modeling with survey weights, stratification and clustering was used to examine the relationships between predictor variables and length of stay as well as in-hospital mortality. Results No significant mortality differences were found among all race and ethnicity groups across each age group. Black neonates and black infants had a longer length of stay (neonatal Estimate = 8.73 days, p = .0034; infant Estimate 1.10 days, p = 0.0253), relative to whites. Government-sponsored insurance was associated with increased odds of neonatal mortality (odds ratio = 1.51, p = .0055), increased length of stay in neonates (Estimate = 4.26 days, p = .0009) and infants (Estimate = 1.52 days, p = .0181), relative to private insurance. Government-sponsored insurance was associated with increased number of chronic conditions, which were also associated with increased LOS (estimate 8.39 days, p < 0.001 in neonates; estimate 3.60 days, p < 0.001 in infants; estimate 1.87 days, p < 0.001 children). Conclusions Racial/ethnic disparities in congenital heart surgical outcomes may be changing compared to previous studies using the KID database. Increased length of stay in children with government-sponsored insurance may reflect expansion of individual states government-sponsored insurance eligibility criteria for children with complex chronic medical conditions. These findings warrant cautious optimism regarding racial and ethnic disparities in

Despite efforts to the contrary, disparities in health and health care persist in the United States. To solve this problem, federal agencies representing different disciplines and perspectives are collaborating on a variety of transdisciplinary research initiatives. The most recent of these initiatives was launched in 2006 when the Centers for Disease Control and Prevention's Office of Public Health Research and the Department of Health and Human Services’ Office of Minority Health brought together federal partners representing a variety of disciplines to form the Federal Collaboration on Health Disparities Research (FCHDR). FCHDR collaborates with a wide variety of federal and nonfederal partners to support and disseminate research that aims to reduce or eliminate disparities in health and health care. Given the complexity involved in eliminating health disparities, there is a need for more transdisciplinary, collaborative research, and facilitating that research is FCHDR's mission. PMID:19762652

Explaining Racial Disparities in Obesity Among Men: Does Place Matter?

National data indicate that Black men have higher rates of obesity than White men. Black men also experience earlier onset of many chronic conditions and premature mortality linked to obesity. Explanations for these disparities have been underexplored, and existing national-level studies may be limited in their ability to explicate these long-standing patterns. National data generally do not account for race differences in risk exposures resulting from racial segregation or the confounding between race and socioeconomic status. Therefore, these differences in obesity may be a function of social environment rather than race. This study examined disparities in obesity among Black and White men living in the same social and environmental conditions, who have similar education levels and incomes using data from the Exploring Health Disparities in Integrated Communities-SWB (EHDIC-SWB) study. The findings were compared with the 2003 National Health Interview Survey (NHIS). Logistic regression was used to examine the association between race and obesity adjusting for demographics, socioeconomic status, and health conditions. In the NHIS, Black men had a higher odds of obesity (odds ratio=1.29, 95% confidence interval=1.12-1.49) than White men. However in the EHDIC-SWB, which accounts for social and environmental conditions of where these men live, Black men had similar odds of obesity (odds ratio=1.06, 95% confidence interval=0.70-1.62) compared with White men. These data highlight the importance of the role that setting plays in understanding race disparities in obesity among men. Social environment may be a key determinant of health when seeking to understand race disparities in obesity among Black and White men. © The Author(s) 2014.

Congenital malformations are the major cause of infant mortality in the United States, but their contribution to overall racial disparity--a major public health concern--is poorly understood. We sought to estimate the contribution of a congenitally acquired central nervous system lesion, Dandy-Walker Syndrome (DWS), to black-white disparity in infant mortality. Data were obtained from the New York State Congenital Malformations Registry, an ongoing population-based validated surveillance system. We compared black to white infants with respect to infant, neonatal, and postneonatal mortality using Cox proportional hazards regression models. A total of 196 live-born neonates were diagnosed with DWS in the state from 1992 to 2005 inclusive. Of these, 53 were non-Hispanic black and 76 were non-Hispanic white. Neonatal mortality was similar for non-Hispanic blacks and non-Hispanic whites (adjusted hazards ratio [AHR], 1.42; 95% CI, 0.52-3.82), but non-Hispanic blacks had an 8-fold increased risk for postneonatal mortality (AHR, 8.26; 95% CI, 2.08-32.72). Adjustment for fetal growth and other maternal and infant characteristics resulted in a 10-fold increased risk of mortality for non-Hispanic black infants as compared to non-Hispanic whites. By contrast, adjustment for preterm birth attenuated the risk, but non-Hispanic black infants were still more than 6 times as likely to die during the postneonatal period than non-Hispanic whites (AHR, 6.36, 95% CI, 1.52-26.60). DWS has one of the largest black-white disparities in postneonatal survival. This underscores the importance of evaluating racial disparities in infant mortality by specific conditions in order to formulate targeted interventions to reduce disparities.

Although epidemiologic studies have established the existence of large sexual orientation disparities in illicit drug use among adolescents and young adults, the determinants of these disparities remain understudied. This study sought to determine whether sexual orientation disparities in illicit drug use are potentiated in states that are characterized by high levels of stigma surrounding sexual minorities. State-level structural stigma was coded using a previously established measure based on a 4-item composite index: (1) density of same-sex couples; (2) proportion of Gay-Straight Alliances per public high school; (3) 5 policies related to sexual orientation discrimination (e.g., same-sex marriage, employment non-discrimination); and (4) public opinion toward homosexuality (aggregated responses from 41 national polls). The index was linked to individual-level data from the Growing Up Today Study, a prospective community-based study of adolescents (2001-2010). Sexual minorities report greater illicit drug use than their heterosexual peers. However, for both men and women, there were statistically significant interactions between sexual orientation status and structural stigma, such that sexual orientation disparities in marijuana and illicit drug use were more pronounced in high-structural stigma states than in low-structural stigma states, controlling for individual- and state-level confounders. For instance, among men, the risk ratio indicating the association between sexual orientation and marijuana use was 24% greater in high- versus low-structural stigma states, and for women it was 28% greater in high- versus low-structural stigma states. Stigma in the form of social policies and attitudes may contribute to sexual orientation disparities in illicit drug use. Copyright © 2015 Elsevier Ltd. All rights reserved.

Racial disparities in health-related quality of life in a cohort of very-low-birth-weight 2- and 3-year-olds with and without asthma.

Children born very low birth weight (VLBW) are at risk for low health-related quality of life (HRQoL), compared with normal-birth-weight peers, and racial disparities may compound the difference. Asthma is the most pervasive health problem among VLBW children and is also more common among black than white children, partly due to unfavourable environmental exposures. This study explores racial disparities in HRQoL among VLBW children and examines whether potential disparities can be explained by asthma and neighbourhood disadvantage. The study population was the Newborn Lung Project, a cohort of infants (n=660) born VLBW in 2003-2004 in Wisconsin, USA, who were followed up at age 2-3. Multilevel linear regression models were used to examine the contributions of asthma, neighbourhood disadvantage, and other child and family socio-demographic covariates, to racial disparities in HRQoL at age 2-3. A child's HRQoL was measured using the Paediatric Quality of Life Inventory 4.0. VLBW, black, non-Hispanic children, on average, score nearly 4 points lower (p<0.01) on HRQoL than do white, non-Hispanic children. Including asthma reduces the difference between black and white children from -3.6 (p<0.01) to 0.08 (p>0.05). The authors found no evidence that the relationship between asthma and HRQoL differs by race. The interaction between neighbourhood disadvantage and asthma is statistically significant, with further examination suggesting that racial disparities are particularly pronounced in the most advantaged neighbourhoods. The authors found that the black disadvantage in HRQoL among 2-3-year-old VLBW children likely stems from a high prevalence of asthma. Neighbourhood attributes did not further explain the disparity, as the racial difference was particularly pronounced in advantaged neighbourhoods.

The Diversity and Disparity in Biomedical Informatics (DDBI) workshop will be focused on complementary and critical issues concerned with enhancing diversity in the informatics workforce as well as diversity in patient cohorts. According to the National Institute of Minority Health and Health Disparities (NIMHD) at the NIH, diversity refers to the inclusion of the following traditionally underrepresented groups: African Americans/Blacks, Asians (>30 countries), American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, Latino or Hispanic (20 countries). Gender, culture, and socioeconomic status are also important dimensions of diversity, which may define some underrepresented groups. The under-representation of specific groups in both the biomedical informatics workforce as well as in the patient-derived data that is being used for research purposes has contributed to an ongoing disparity; these groups have not experienced equity in contributing to or benefiting from advancements in informatics research. This workshop will highlight innovative efforts to increase the pool of minority informaticians and discuss examples of informatics research that addresses the health concerns that impact minority populations. This workshop topics will provide insight into overcoming pipeline issues in the development of minority informaticians while emphasizing the importance of minority participation in health related research. The DDBI workshop will occur in two parts. Part I will discuss specific minority health & health disparities research topics and Part II will cover discussions related to overcoming pipeline issues in the training of minority informaticians.

Residential Segregation and Racial Cancer Disparities: A Systematic Review.

This paper provides the first review of empirical studies of segregation and black-white cancer disparities. We searched all years of PubMed (through May 2016) using these terms: racial segregation, residential segregation, neighborhood racial composition (first terms) and (second terms) cancer incidence, mortality, survival, stage at diagnosis, screening. The 17 (of 668) articles that measured both segregation and a cancer outcome were retained. Segregation contributed significantly to cancer and to racial cancer disparities in 70% of analyses, even after controlling for socioeconomic status and health insurance. Residing in segregated African-American areas was associated with higher odds of later-stage diagnosis of breast and lung cancers, higher mortality rates and lower survival rates from breast and lung cancers, and higher cumulative cancer risks associated with exposure to ambient air toxics. There were no studies of many types of cancer (e.g., cervical). Studies differed in their measure of segregation, and 40% used an invalid measure. Possible mediators of the segregation effect usually were not tested. Empirical analysis of segregation and racial cancer disparities is a recent area of research. The literature is limited to 17 studies that focused primarily on breast cancer. Studies differed in their measure of segregation, yet segregation nonetheless contributed to cancer and to racial cancer disparities in 70% of analyses. This suggests the need for further research that uses valid measures of segregation, examines a variety of types of cancers, and explores the variables that may mediate the segregation effect.

Logan, Robert A

2017-01-01

This chapter compares the conceptual foundations of health literacy and health disparities. It details some of the conceptual differences between health literacy and health disparities and explains some similarities that suggest the need for increased research collaboration. The chapter is among the first to address the structural and social determinants of health together and explain that future research needs to assess their interactions. Overall, the chapter creates a conceptual foundation as well as challenges future scholars/practitioners to take more multidimensional approaches to assess health's determinants. The chapter also attempts to demonstrate there is nothing more practical than good theory, or clear conceptual foundations. The chapter is divided into four sections that address the following topics: three conceptual frameworks about the determinants of health; opportunities in health disparities and health literacy research; seeking an expanded, multidimensional conceptual approach to health literacy and health disparities research; as well as a conclusion. The chapter suggests there are vacuums in current research knowledge that need future attention - especially regarding the integration of health literacy and health disparities research.

Three-dimensional (3-D) scene reconstruction from stereoscopic binocular laparoscopic videos is an effective way to expand the limited surgical field and augment the structure visualization of the organ being operated in minimally invasive surgery. However, currently available reconstruction approaches are limited by image noise, occlusions, textureless and blurred structures. In particular, an endoscope inside the body only has the limited light source resulting in illumination non-uniformities in the visualized field. These limitations unavoidably deteriorate the stereo image quality and hence lead to low-resolution and inaccurate disparity maps, resulting in blurred edge structures in 3-D scene reconstruction. This paper proposes an improved stereo correspondence framework that integrates cost-volume filtering with joint upsampling for robust disparity estimation. Joint bilateral upsampling, joint geodesic upsampling, and tree filtering upsampling were compared to enhance the disparity accuracy. The experimental results demonstrate that joint upsampling provides an effective way to boost the disparity estimation and hence to improve the surgical endoscopic scene 3-D reconstruction. Moreover, the bilateral upsampling generally outperforms the other two upsampling methods in disparity estimation.

How Resource Dynamics Explain Accumulating Developmental and Health Disparities for Teen Parents’ Children

2014-01-01

This study examines the puzzle of disparities experienced by U.S. teen parents’ young children, whose health and development increasingly lag behind those of peers while their parents are simultaneously experiencing socioeconomic improvements. Using the nationally representative Early Childhood Longitudinal Study-Birth Cohort (2001–2007; N ≈ 8,600), we assess four dynamic patterns in socioeconomic resources that might account for these growing developmental and health disparities throughout early childhood and then test them in multilevel growth curve models. Persistently low socioeconomic resources constituted the strongest explanation, given that consistently low income, maternal education, and assets fully or partially account for growth in cognitive, behavioral, and health disparities experienced by teen parents’ children from infancy through kindergarten. That is, although teen parents gained socioeconomic resources over time, those resources remained relatively low, and the duration of exposure to limited resources explains observed growing disparities. Results suggest that policy interventions addressing the time dynamics of low socioeconomic resources in a household, in terms of both duration and developmental timing, are promising for reducing disparities experienced by teen parents’ children.

To longitudinally examine gender and racial disparities in driving cessation among older adults. Data came from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) Study (N = 1,789). Logistic generalized estimating equations (GEE) were used to identify predictors of driving cessation; stratified analysis and interaction terms were used to determine whether factors differed by gender and race. Two hundred and five (11.5%) participants stopped driving over the study period. Education was associated with increased risk of cessation for men (adjusted odds ratio [AOR] =1.40, 95% confidence interval [CI] =1.10 to 1.78), but decreased risk for women (AOR = 0.90, 95% CI = 0.82-0.98). Being married was associated with lower risk of cessation for men (AOR = 0.18, 95% CI = 0.06-0.56) but was unrelated to cessation for women (AOR = 1.00, 95% CI = 0.56-1.80). Results were consistent with the hypothesis that racial disparities in cessation widen with increasing age. Factors predictive of driving cessation vary by gender. Racial disparities in cessation are wider at older ages. Transportation policies and programs should account for social determinants and aim to address social disparities in driving mobility among older adults.

We used qualitative methods (semi-structured interviews with healthcare providers) to explore: 1) the role of narratives as a vehicle for raising awareness and engaging providers about the issue of healthcare disparities and 2) the extent to which different ways of framing issues of race within narratives might lead to message acceptance for providers' whose preexisting beliefs about causal attributions might predispose them to resist communication about racial healthcare disparities. Individual interviews were conducted with 53 providers who had completed a prior survey assessing beliefs about disparities. Participants were stratified by the degree to which they believed providers contributed to healthcare inequality: low provider attribution (LPA) versus high provider attribution (HPA). Each participant read and discussed two differently framed narratives about race in healthcare. All participants accepted the "Provider Success" narratives, in which interpersonal barriers involving a patient of color were successfully resolved by the provider narrator, through patient-centered communication. By contrast, "Persistent Racism" narratives, in which problems faced by the patient of color were more explicitly linked to racism and remained unresolved, were very polarizing, eliciting acceptance from HPA participants and resistance from LPA participants. This study provides a foundation for and raises questions about how to develop effective narrative communication strategies to engage providers in efforts to reduce healthcare disparities.

In the last 20 years, the issue of disparities in health between racial/ethnic groups has moved from the realm of common sense and anecdote to the realm of science. Hard, cold data now force us to consider what many had long taken for granted. Not only does health differ by race/ethnicity, but our health care system itself is deeply biased. From lack of diversity in the leadership and workforce, to ethnocentric systems of care, to biased clinical decision-making, the American health care system is geared to treat the majority, while the minority suffers. The photos shown here are of patients and scenes that recall some of the important landmarks in research on racial/ethnic disparities in health. The purpose is to put faces and humanity onto the numbers. While we now have great bodies of evidence upon which to lobby for change, in the end, each statistic still represents a personal tragedy or an individual triumph.

Disparities in access to and quality of health care along racial and ethnic lines are an important national problem. Health care purchasers and payers have a potentially important role to play in alleviating this problem. Using national surveys of 609 employers and 252 health plans with HMO products in 41 U.S. markets, we examined awareness of racial and ethnic disparities in health care access and quality, perceptions of employer and health plan role in addressing disparities, and reported efforts to measure and reduce disparities. Our findings suggest that most health plans and many employers are aware of the existence of substantial disparities and that health plans, but not employers, have taken steps to examine and influence patterns of care by race and ethnicity among their members.

Effects of Geography on Mental Health Disparities on Sexual Minorities in New York City.

PubMed

Felson, Jacob; Adamczyk, Amy

Gay and lesbian individuals have higher rates of psychological distress than do heterosexual individuals. The minority stress hypothesis attributes this disparity to adversity-related stress experienced by sexual minorities. In support of this idea, research in the U.S. has generally found that mental health disparities between sexual minorities and others are narrower in places where tolerance is relatively high. However, few studies have examined disparities between sexual minorities and others in neighborhoods where sexual minorities are most highly concentrated. Likewise, little research attention has been given to disparities for people who move to more tolerant places from less tolerant states and countries. Using data from the New York City Community Health Survey, we found some evidence that disparities between sexual minorities and others were lower in areas with higher concentrations of sexual minorities. However, disparities did not vary by the tolerance level of the state of birth among those born in the U.S. and were actually lower among those born in the least tolerant nations. These results complicate the idea that there is a dose-response relationship between tolerance and psychological distress among sexual minorities.

Mandated Coverage of Preventive Care and Reduction in Disparities: Evidence From Colorectal Cancer Screening

Objectives. We identified correlates of racial/ethnic disparities in colorectal cancer screening and changes in disparities under state-mandated insurance coverage. Methods. Using Behavioral Risk Factor Surveillance System data, we estimated a Fairlie decomposition in the insured population aged 50 to 64 years and a regression-adjusted difference-in-difference-in-difference model of changes in screening attributable to mandates. Results. Under mandated coverage, blood stool test (BST) rates increased among Black, Asian, and Native American men, but rates among Whites also increased, so disparities did not change. Endoscopic screening rates increased by 10 percentage points for Hispanic men and 3 percentage points for non-Hispanic men. BST rates fell among Hispanic relative to non-Hispanic men. We found no changes for women. However, endoscopic screening rates improved among lower income individuals across all races and ethnicities. Conclusions. Mandates were associated with a reduction in endoscopic screening disparities only for Hispanic men but may indirectly reduce racial/ethnic disparities by increasing rates among lower income individuals. Findings imply that systematic differences in insurance coverage, or health plan fragmentation, likely existed without mandates. These findings underscore the need to research disparities within insured populations. PMID:25905835

The search for an unrelated donor must be based on the HLA typing of the donor and the host. PCR techniques have facilitated high-resolution HLA typing, but they have also elicited questions about the real impact of the various disparities on the progress of the graft Thus, whereas a donor used to be accepted based on HLA-A and B Identity determined by serology and HLA-DRB1 through molecular biology techniques, now a donor is required to have a 70/70 Identity for loci HLA-A, B, C, DRB7, and DQB7. Furthermore, the real effect of the disparities in the sixth locus of the major histocompatibility complex-HLA-DPBT-is still in doubt. This study intends to conduct a literature review of the clinical impact of the various HLA disparities In transplants from unrelated donors.

Population specific studies in prostate cancer (PCa) reveal a unique heterogeneous etiology. Various factors, such as genetics, environment and dietary regimen seems to determine disease progression, therapeutic resistance and rate of mortality. Enormous disparity documented in disease incidences, aggressiveness and mortality in PCa among AAs (African Americans) and CAs (Caucasian Americans) is attributed to the variations in genetics, epigenetics and their association with metabolism. Scientific and clinical evidences have revealed the influence of variations in Androgen Receptor (AR), RNAse L, macrophage scavenger receptor 1 ( MRS1 ), androgen metabolism by cytochrome P450 3A4, differential regulation of microRNAs, epigenetic alterations and diet in racial disparity in PCa incidences and mortality. Concerted efforts are needed to identify race specific prognostic markers and treatment regimen for a better management of the disease.

Does Medicaid Managed Care Help Equalize Racial and Ethnic Disparities in Utilization?

To estimate the impact of different forms of Medicaid managed care (MMC) delivery on racial and ethnic disparities in utilization. Longitudinal, administrative data on 101,649 children in Kentucky continuously enrolled in Medicaid between January 1997 and June 1999. Outcomes considered are monthly professional, outpatient, and inpatient utilization. We apply an intent-to-treat, instrumental variables analysis using the staggered geographic implementation of MMC to create treatment and control groups of children. The implementation of MMC reduced monthly professional visits by a smaller degree for non-whites than whites (3.8 percentage points vs. 6.2 percentage points), thereby helping to equalize the initial racial/ethnic disparity in utilization. The Passport MMC program in the Louisville-centered region statistically significantly reduced disparities for professional visits (closing the gap by 8.0 percentage points), while the Kentucky Health Select MMC program in the Lexington-centered region did not. No substantive impact on disparities was found for either outpatient or inpatient utilization in either program. We find evidence that MMC has the possibility to reduce racial/ethnic disparities in professional utilization. More work is needed to determine which managed care program characteristics drive this result. © 2015 The Authors.

The overall goal of this research project was to assess ethnic disparities in monetary compensation among construction workers injured on the job through the linkage of medical records and workers' compensation data. Probabilistic linkage of medical records with workers' compensation claim data. In the final multivariable robust regression model, compensation was $5824 higher (P = 0.030; 95% confidence interval: 551 to 11,097) for white non-Hispanic workers than for other ethnic groups when controlling for injury severity, affected body region, type of injury, average weekly wage, weeks of temporary total disability, percent permanent partial disability, death, or attorney use. The analysis indicates that white non-Hispanic construction workers are awarded higher monetary settlements despite the observation that for specific injuries the mean temporary total disability and permanent partial disability were equivalent to or lower than those in Hispanic and black construction workers.

Health disparities are a persistent problem in many high-income countries. Health policymakers recognize the need to develop systematic methods for documenting and tracking these disparities in order to reduce them. The experience of the U.S., which has a well-established health disparities monitoring infrastructure, provides useful insights for other countries. This article provides an in-depth review of health disparities monitoring in the U.S. Lessons of potential relevance for other countries include: 1) the integration of health disparities monitoring in population health surveillance, 2) the role of political commitment, 3) use of monitoring as a feedback loop to inform future directions, 4) use of monitoring to identify data gaps, 5) development of extensive cross-departmental cooperation, and 6) exploitation of digital tools for monitoring and reporting. Using Israel as a case in point, we provide a brief overview of the healthcare and health disparities landscape in Israel, and examine how the lessons from the U.S. experience might be applied in the Israeli context. The U.S. model of health disparities monitoring provides useful lessons for other countries with respect to documentation of health disparities and tracking of progress made towards their elimination. Given the persistence of health disparities both in the U.S. and Israel, there is a need for monitoring systems to expand beyond individual- and healthcare system-level factors, to incorporate social and environmental determinants of health as health indicators/outcomes.

The Role of Binocular Disparity in Stereoscopic Images of Objects in the Macaque Anterior Intraparietal Area

Romero, Maria C.; Van Dromme, Ilse C. L.; Janssen, Peter

2013-01-01

Neurons in the macaque Anterior Intraparietal area (AIP) encode depth structure in random-dot stimuli defined by gradients of binocular disparity, but the importance of binocular disparity in real-world objects for AIP neurons is unknown. We investigated the effect of binocular disparity on the responses of AIP neurons to images of real-world objects during passive fixation. We presented stereoscopic images of natural and man-made objects in which the disparity information was congruent or incongruent with disparity gradients present in the real-world objects, and images of the same objects where such gradients were absent. Although more than half of the AIP neurons were significantly affected by binocular disparity, the great majority of AIP neurons remained image selective even in the absence of binocular disparity. AIP neurons tended to prefer stimuli in which the depth information derived from binocular disparity was congruent with the depth information signaled by monocular depth cues, indicating that these monocular depth cues have an influence upon AIP neurons. Finally, in contrast to neurons in the inferior temporal cortex, AIP neurons do not represent images of objects in terms of categories such as animate-inanimate, but utilize representations based upon simple shape features including aspect ratio.

Reproductive health screenings are a necessary part of quality health care. However, sexual minorities underutilize Papanicolaou (Pap) tests more than heterosexuals do, and the reasons are not known. Our objective was to examine if less hormonal contraceptive use or less positive health beliefs about Pap tests explain sexual orientation disparities in Pap test intention and utilization. We used multivariable regression with prospective data gathered from 3821 females aged 18 to 25 years in the Growing Up Today Study (GUTS). Among lesbians, less hormonal contraceptive use explained 8.6% of the disparities in Pap test intention and 36.1% of the disparities in Pap test utilization. Less positive health beliefs associated with Pap testing explained 19.1% of the disparities in Pap test intention. Together, less hormonal contraceptive use and less positive health beliefs explained 29.3% of the disparities in Pap test intention and 42.2% of the disparities in Pap test utilization. Hormonal contraceptive use and health beliefs, to a lesser extent, help to explain sexual orientation disparities in intention and receipt of a Pap test, especially among lesbians.

Objective To evaluate whether Medicare Part D has reduced racial/ethnic disparities in prescription drug utilization and spending. Data Nationally representative data on white, African American, and Hispanic Medicare seniors from the 2002–2009 Medical Expenditure Panel Survey are analyzed. Five measures are examined: filling any prescriptions during the year, the number of prescriptions filled, total annual prescription spending, annual out-of-pocket prescription spending, and average copay level. Study Design We apply the Institute of Medicine's definition of a racial/ethnic disparity and adopt a difference-in-difference-in-differences (DDD) estimator using a multivariate regression framework. The treatment group consists of Medicare seniors, the comparison group, adults without Medicare aged 55–63 years. Principal Findings Difference-in-difference-in-differences estimates suggest that for African Americans Part D increased the disparity in annual spending on prescription drugs by $258 (p = .011), yet had no effect on other measures of prescription drug disparities. For Hispanics, DDD estimates suggest that the program reduced the disparities in annual number of prescriptions filled, annual total and out-of-pocket spending on prescription drugs by 2.9 (p = .077), $282 (p = .019) and $143 (p < .001), respectively. Conclusion Medicare Part D had mixed effects. Although it reduced Hispanic/white disparities related to prescription drugs among seniors, it increased the African American/white disparity in total annual spending on prescription drugs.

During past decades, the number of dentists has continuously increased in Iran. Beside the quantity, the distribution of dentists affects the oral health status of population. The current study aimed to assess the pure and social disparities in distribution of dentists across the provinces in Iran in 2009. Data on provinces’ characteristics, including population and social situation, were obtained from multiple sources. The disparity measures (including Gini coefficient, index of dissimilarity, Gaswirth index of disparity and relative index of inequality (RII)) and pairwise correlations were used to evaluate the pure and social disparities in the number of dentists in Iran. On average, there were 28 dentists per 100,000 population in the country. There were substantial pure disparities in the distribution of dentists across the provinces in Iran. The unadjusted and adjusted RII values were 3.82 and 2.13, respectively; indicating area social disparity in favor of people in better-off provinces. There were strong positive correlations between density of dentists and better social rank. It is suggested that the results of this study should be considered in conducting plans for redistribution of dentists in the country. In addition, further analyses are needed to explain these disparities. PMID:23648443

To identify and quantify the sources of the urban-rural disparity in facility-acquired contracture rates in nursing homes. Survey inspection data of U.S. nursing homes from 1999 to 2008 and standardized national rural definition file from the Rural-Urban Commuting Area Codes. We estimated regressions of facility-level contracture rate as a function of urban-rural categories (urban, micropolitan, small rural town, and isolated small rural town) and other related facility characteristics to identify size of the urban-rural disparity. We used Blinder-Oaxaca decomposition techniques to determine the extent to which the disparity is attributable to the differences in facility and aggregate resident characteristics. Rural nursing homes have higher contracture rates than urban nursing homes. About half of the urban-rural disparity is explained by differences in observable characteristics among urban and rural nursing homes. Differences in staffing levels explain less than 5 percent of the disparity, case-mix explains 6-8 percent, and structure and operational characteristics account for 10-22 percent of the disparity. While a lower level and quality of staffing are a concern for rural nursing homes, facility structure and funding sources explain a larger proportion of the urban-rural disparity in the quality of care. © Health Research and Educational Trust.

Objectives. To examine gender disparities in cognitive functioning in India and the extent to which education explains this disparity in later life. Methods. This study uses baseline interviews of a prospective cohort study of 1,451 community-residing adults 45 years of age or older in four geographically diverse states of India (Karnataka, Kerala, Punjab, Rajasthan). Data collected during home visits includes cognitive performance tests, and rich sociodemographic, health, and psychosocial variables. The cognitive performance tests include episodic memory, numeracy, and a modified version of the Mini-Mental State Examination. Results. We find gender disparity in cognitive function in India, and this disparity is greater in the north than the south. We also find that gender disparities in educational attainment, health, and social and economic activity explain the female cognitive disadvantage in later life. Discussion. We report significant gender disparities in cognitive functioning among older Indian adults, which differ from gender disparities in cognition encountered in developed countries. Our models controlling for education, health status, and social and economic activity explain the disparity in southern India but not the region-specific disparity in the northern India. North Indian women may face additional sources of stress associated with discrimination against women that contribute to persistent disadvantages in cognitive functioning at older ages.

Advances in a wide array of scientific technologies have brought data of unprecedented volume and complexity into the oncology research space. These novel big data resources are applied across a variety of contexts-from health services research using data from insurance claims, cancer registries, and electronic health records, to deeper and broader genomic characterizations of disease. Several forms of big data show promise for improving our understanding of racial disparities in breast cancer, and for powering more intelligent and far-reaching interventions to close the racial gap in breast cancer survival. In this article we introduce several major types of big data used in breast cancer disparities research, highlight important findings to date, and discuss how big data may transform breast cancer disparities research in ways that lead to meaningful, lifesaving changes in breast cancer screening and treatment. We also discuss key challenges that may hinder progress in using big data for cancer disparities research and quality improvement.

Triple-negative breast cancer in African-American women: disparities versus biology

PubMed Central

Dietze, Eric C.; Sistrunk, Christopher; Miranda-Carboni, Gustavo; O’Regan, Ruth; Seewaldt, Victoria L.

2017-01-01

Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype that disproportionately affects BRCA1 mutation carriers and young women of African origin. There is evidence that African-American women with TNBC have worse clinical outcomes than women of European descent. However, it is unclear whether survival differences persist after adjusting for disparities in access to health-care treatment, co-morbid disease and income. It remains controversial whether TNBC in African-American women is a molecularly distinct disease or whether African-American women have a higher incidence of aggressive biology driven by disparities: there is evidence in support of both. Understanding the relative contributions of biology and disparities is essential for improving the poor survival rate of African-American women with TNBC. PMID:25673085

Minimal Similarity between Biogeographic Patterns of Morphological Disparity and Taxonomic Richness in Extant Coccolithophores

NASA Astrophysics Data System (ADS)

Villarosa Garcia, M.

2016-02-01

Morphologic disparity, carries both an ecological and evolutionary signal and, where practical, might bridge ecological processes observed in modern seas with macroevolutionary processes observed in the fossil record, complementing taxonomic diversity studies. I compare the biogeography of morphologic disparity and taxonomic richness in extant coccolithophores to understand the role of environmental conditions in their spatial partitioning. I analyze 112 traits in 125 species and measure geographic extent as the occupation of pelagic biogeographic provinces (sensu Spalding et al. 2012). In the modern ocean, coccolithophorid species richness increases towards the equator, peaking in the subtropics, and certain biomes harbor more species. In contrast, their morphologic disparity does not vary across latitudes and biomes, yielding similar values of variance and mean pair-wise distances. Disparity is weakly correlated to richness across clades and biomes (no clear latitudinal pattern). I also study the morphological breadth of clades in a multivariate morphospace plotted as principal coordinate axes (PCO). Clades have distinct centroids but show some overlap in volume. However, they are completely separate when using canonical variates analysis (CVA) on these PCO axes. The centroids of latitudinal groups are closely spaced, and overlap in morphospace, but again separate with CVA. However biome groups can't be distinguished using PCO or CVA. Although clades with the most species tend to have high disparity, most clades are found in every region yielding similar group disparities. Despite the fact that taxonomic diversity is spatially partitioned on the globe, morphologic disparity has no such organization. Past studies using marine gastropods (Roy et al. 2001; McClain 2005), cuttlefish (Neige 2003), and birds (Jønsson et al. 2015) also find minimal support for a biogeographic structure of disparity, highlighting the profound nature of this differential response.
