Social determinants of health are the conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning and quality of life outcomes and risks - these social determinants of health often aid in explaining the racial and ethnic health inequities present in the United States (US). The root cause of these social determinants of health has been tied to structural racism, and residential segregation is one such domain of structural racism that allows for the operationalization of the geography of structural racism. This review focuses on three residential segregation measures that are often utilized to capture segregation as a function of race/ethnicity, income, and simultaneously race/ethnicity and income. Empirical findings related to the spatial and spatio-temporal heterogeneity of these residential segregation measures are presented. We also discuss some of the implications of utilizing these three residential segregation measures.

In the U.S., inequities by race/ethnicity in health outcomes, such as in the HIV epidemic, are long standing but have come to the forefront during the COVID-19 pandemic. There is growing recognition of the role of structural racism in racialized health inequities, yet the conceptualization and operationalization of structural racism in HIV research lags. We conducted a scoping review of existing published literature, between 1999-April 2024, conceptualizing and measuring structural racism\'s impact among people living with or at risk for HIV in the U.S. Our initial search yielded 236 unique articles, which after title and abstract screening yielded ten articles meeting full text review criteria. We then extracted key parameters, such as conceptualization, method of measurement of structural racism, study aims, design, and findings. Three of the articles were qualitative studies that conceptualized structural racism using (1) the social network model, (2) individual and structural intersectionality and (3) critical race theory. Operationalization of structural racism within the seven quantitative studies fell into three categories: (1) structural level, (2) a scale of experiences of racism, including structural racism, and (3) using explanatory demographic factors as downstream measures of the effects of structural racism. The variance in the conceptualization and operationalization of structural racism highlights the different interpretations of structural racism in its applications to the field of HIV research. Given the vast racial/ethnic inequities in HIV, we propose three overarching suggestions for next steps in improving the conduct of research on structural racism in HIV: (1) we must prioritize measuring racism past the individual and interpersonal levels to consider systemic factors at a societal level that manifest as structural racism to improve HIV outcomes in the U.S., (2) consider intergenerational effects of structural racism through the use of longitudinal data, and (3) broaden the agenda of structural racism to incorporate other systems of oppression. Additionally, broadening the scope of funding and inclusion of more researchers and individuals with lived experiences to support structural racism research to drive the scientific agenda and design of structural-level interventions will not only bolster achieving the U.S. Ending the HIV Epidemic goals but will do so by addressing inequities.

Since 2020, brought to the forefront by movements such as Black Lives Matter and Idle No More, it has been widely acknowledged that systemic racism contributes to racially differentiated health outcomes. Health professional educators have been called to address such disparities within healthcare, policy, and practice. To tackle structural racism within healthcare, one avenue that has emerged is the creation of medical education interventions within postgraduate residency medical programming. The objective of this scoping review is to examine the current literature on anti-racist educational interventions, that integrate a systemic or structural view of racism, within postgraduate medical education. Through the identification and analysis of 23 papers, this review identified three major components of interest across medical interventions, including (a) conceptualization, (b) pedagogical issues, and (c) outcomes & evaluation. There were overlapping points of discussion and analysis within each of these components. Conceptualization addressed how researchers conceptualized racism in different ways, the range of curricular content educators chose to challenge racism, and the absence of community\'s role in curricular development. Pedagogical issues addressed knowledge vs. skills-based teaching, and tensions between one-time workshops and integrative curriculum. Outcomes and evaluation highlighted self-reported Likert scales as dominant types of evaluation, self-evaluation in educational interventions, and misalignments between intervention outcomes and learning objectives. The findings are unique in their in-depth exploration of anti-racist medical interventions within postgraduate medical education programming, specifically in relation to efforts to address systemic and structural racism. The findings contribute a meaningful review of the current state of the field of medical education and generate new conversations about future possibilities for a broader anti-racist health professions curriculum.

UNASSIGNED: Sudden cardiac arrest is associated with high morbidity and mortality. Despite having a disproportionate burden of sudden cardiac death (SCD), rates of primary and secondary prevention of SCD with implantable cardioverter-defibrillator (ICD) therapy are lower among eligible racially minoritized patients. This review highlights the racial and ethnic disparities in ICD utilization, associated barriers to ICD care, and proposed interventions to improve equitable ICD uptake.
UNASSIGNED: Racially minoritized populations are disproportionately eligible for ICD therapy but are less likely to see cardiac specialists, be counseled on ICD therapy, and ultimately undergo ICD implantation, fueling disparate outcomes. Racial disparities in ICD utilization are multifactorial, with contributions at the patient, provider, health system, and structural/societal level.
UNASSIGNED: Racial and ethnic disparities have been demonstrated in preventing SCD with ICD use. Proposed strategies to mitigate these disparities must prioritize care delivery and access to care for racially minoritized patients, increase the diversification of clinical and implementation trial participants and the healthcare workforce, and center reparative justice frameworks to rectify a long history of racial injustice.

Inclusion and diversity in precision oncology are essential in reducing cancer disparities among racial and ethnic groups. However, present studies have favored the recruitment and participation of Whites, with limited applicability of their results to minority groups. Many reasons for their underrepresentation are downstream manifestations of structural racism. Therefore, this scoping review provides a precise mapping of recruitment and participation barriers for minorities in precision oncology that are associated with structural racism, including a critical appraisal of how disciplinary norms, paradigms, and tools used therein could inadvertently contribute to unforeseen inclusion and diversity challenges. Empirical and theoretical publications from Web of Science and PubMed were searched and analyzed to identify recruitment and participation barriers for minorities in precision oncology. In addition, using the public health critical race praxis (PHCRP) as guiding analytical framework, empirical studies were analyzed to identify unforeseen barriers resulting from simplification processes, assumptions, norms, paradigms, and tools used during the research process. One-hundred thirty-five barriers to recruitment and participation were identified or reported in included publications. They were subsequently categorized as being a manifestation of one of the following forms of racism, namely internalized, interpersonal, institutional, and structural racism. The PCHRP analysis revealed four additional factors to be considered in precision oncology studies in ensuring appropriate representation of their study populations. Future interventions aimed at reducing health disparities should focus predominantly on barriers associated with structural and institutional racism, which should then have ripple effects on other forms of racism. Importantly, the four factors identified through the PHCRP framework could further explain the lower participation rates of minorities in precision oncology and related activities. Therefore, they should be given due consideration by all stakeholders involved in the precision oncology ecosystem, from researchers and healthcare professionals to policy-makers, research ethics committees, and funders.

BACKGROUND: Limited literature exists on structural racism measures on health outcomes for Asian Americans, Native Hawaiians, and Pacific Islanders (AAs and NH/PIs). AAs and NH/PIs make up approximately 6.2% of the U.S. population and consist of diverse ethnic subgroups with distinct languages, cultures, religions, socioeconomic statuses, and historical backgrounds. The lack of disaggregated data collection and contextualized measures hinders our understanding of how structural racism affects health outcomes in these populations.
METHODS: We conducted a scoping review to assess the extent to which measures of structural racism are used in research with AAs and NH/PIs. Databases, including CINAHL, EBSCO, PsychINFO, PubMed, Scopus, and Social Science Citation Index, were searched for peer-reviewed articles on the measures of and empirical impacts of structural racism on AA and NH/PI health. We identified 23 full-text articles from a pool of 11,660 screened articles. Four articles were included in the final analysis.
RESULTS: Among the selected studies, two studies identified an association between racial segregation and mental and behavioral health outcomes within AAs and NH/PIs. The other two studies found redlining on chronic health outcomes in these communities. These studies uncovered associations between government systems and policies and AA and NH/PI health outcomes.
CONCLUSIONS: Existing measures may not adequately capture the complex relationships between structural racism and health outcomes in AAs and NH/PIs. Future research should contextualize and operationalize the multifaceted manifestations of structural racism unique to AAs and NH/PIs to achieve health equity.

BACKGROUND: Amid persistent disparities in Covid-19 vaccination and burgeoning research on vaccine hesitancy (VH), we conducted a scoping review to identify multilevel determinants of Covid-19 VH and under-vaccination among marginalized populations in the U.S. and Canada.
METHODS: Using the scoping review methodology developed by the Joanna Briggs Institute, we designed a search string and explored 7 databases to identify peer-reviewed articles published from January 1, 2020-October 25, 2022. We combine frequency analysis and narrative synthesis to describe factors influencing Covid-19 VH and under-vaccination among marginalized populations.
RESULTS: The search captured 11,374 non-duplicated records, scoped to 103 peer-reviewed articles. Among 14 marginalized populations identified, African American/Black, Latinx, LGBTQ+, American Indian/Indigenous, people with disabilities, and justice-involved people were the predominant focus. Thirty-two factors emerged as influencing Covid-19 VH, with structural racism/stigma and institutional mistrust (structural)(n = 71) most prevalent, followed by vaccine safety (vaccine-specific)(n = 62), side effects (vaccine-specific)(n = 50), trust in individual healthcare provider (social/community)(n = 38), and perceived risk of infection (individual)(n = 33). Structural factors predominated across populations, including structural racism/stigma and institutional mistrust, barriers to Covid-19 vaccine access due to limited supply/availability, distance/lack of transportation, no/low paid sick days, low internet/digital technology access, and lack of culturally- and linguistically-appropriate information.
CONCLUSIONS: We identified multilevel and complex drivers of Covid-19 under-vaccination among marginalized populations. Distinguishing vaccine-specific, individual, and social/community factors that may fuel decisional ambivalence, more appropriately defined as VH, from structural racism/structural stigma and systemic/institutional barriers to vaccination access may better support evidence-informed interventions to promote equity in access to vaccines and informed decision-making among marginalized populations.

UNASSIGNED: Outcomes for amyotrophic lateral sclerosis (ALS) patients are improved with prompt diagnosis, earlier initiation of disease-modifying treatments, and participation in a multidisciplinary clinic. We studied diagnostic delay and disease severity at time of clinic presentation between Black and non-Hispanic Caucasian ALS patients.
UNASSIGNED: We performed a retrospective analysis of non-Hispanic Caucasian and Black ALS patients seen in the Virginia Commonwealth University Health System multidisciplinary ALS clinic between 2017 and 2023. Diagnostic delay, ALS Functional Rating Scale-Revised (ALSFRS-R) and upright forced vital capacity (FVC) scores at baseline appointment were collected. Patient\'s distance from clinic and affluency of residential neighborhood were evaluated.
UNASSIGNED: We analyzed 172 non-Hispanic Caucasian and 33 Black ALS patients. Black patients had a 64% increase in diagnostic delay compared to non-Hispanic Caucasian patients. Black patients had a lower performance on ALSFRS-R (5.3 points, p < 0.001) and FVC (17.9 percentage points p < 0.001) at time of first clinic visit. Black patients lived closer to clinic, with higher proportion living in the city of Richmond, but in less affluent areas with lower median house income ($55,300 ± 22,600 vs $69,900 ± 23,700).
UNASSIGNED: Our findings demonstrate a large racial difference in ALS diagnostic delay, and greater disease severity and lower respiratory function at time of diagnosis for Black ALS patients. Delay in diagnosis prolongs access to disease-modifying therapies, multidisciplinary care, durable medical equipment, and respiratory and nutritional support. Potential sources of these racial disparities include providers\' implicit bias and structural racism.

With the unanimous approval of the Intersectoral Global Action Plan on epilepsy and other neurological disorders by the World Health Organization in May 2022, there are strong imperatives to work towards equitable neurological care.
Using epilepsy as an entry point to other neurologic conditions, we discuss disparities faced by marginalized groups including racial/ethnic minorities, Americans living in rural communities, and Americans with low socioeconomic status.
The National Institute on Minority Health Disparities Research Framework (NIMHD) was used to conduct a narrative review through a health equity lens to create an adapted framework for epilepsy and propose approaches to working towards equitable epilepsy and neurological care.
In this narrative review, we identified priority populations (racial and ethnic minority, rural-residing, and low socioeconomic status persons with epilepsy) and outcomes (likelihood to see a neurologist, be prescribed antiseizure medications, undergo epilepsy surgery, and be hospitalized) to explore disparities in epilepsy and guide our focused literature search using PubMed. In an adapted NIMHD framework, we examined individual, interpersonal, community, and societal level contributors to health disparities across five domains: (1) behavioral, (2) physical/built environment, (3) sociocultural, (4) environment, and (5) healthcare system. We take a health equity approach to propose initiatives that target modifiable factors that impact disparities and advocate for sustainable change for priority populations.
To improve equity, healthcare providers and relevant societal stakeholders can advocate for improved care coordination, referrals for epilepsy surgery, access to care, health informatics interventions, and education (i.e., to providers, patients, and communities). More broadly, stakeholders can advocate for reforms in medical education, and in the American health insurance landscape.
Equitable healthcare should be a priority in neurological care.

This scoping review summarized findings and key measures from U.S.-based studies that 1) examined associations between geographic indicators of structural racism (e.g., redlining, racial segregation) and access to food retailers (e.g., supermarkets, convenience stores) or 2) documented disparities in access by neighborhood racial/ethnic composition. In 2022, relevant scientific literature was reviewed using Covidence software. Independent reviewers examined 13,069 citations; 163 citations advanced to the full-text review stage and 70 were selected for inclusion. Twenty-one studies (30%) linked one or more indicator of structural racism to food retailer access while 49 (70%) solely examined differences in access by neighborhood racial/ethnic composition. All studies featuring indicators of structural racism reported significant findings; however, indicators varied across studies making it difficult to make direct comparisons. Key indicators of structural racism in the food access literature included redlining (n = 3), gentrification (n = 3), and racial segregation (n = 4). Many U.S.-based studies have evaluated food retailer access by neighborhood racial/ethnic composition. Moving forward, studies should model indicators of structural racism and determine their influence on geographic access to large and small food retailers.
