Perspective: Nutrition Health Disparities Framework: A Model to Advance Health Equity.

Disparities in nutrition, such as poor diet quality and inadequate nutrient intake, arise from multiple factors and are related to adverse health outcomes such as obesity, diabetes, cardiovascular disease, and some cancers. The aim of the current perspective is to present a nutrition-centric socioecological framework that delineates determinants and factors that contribute to diet and nutrition-related disparities among disadvantaged populations. The Nutrition Health Disparities Framework (NHDF) describes the domains (biological, behavioral, physical/built environment, sociocultural environment, and healthcare system) that influence nutrition-related health disparities through the lens of each level of influence (that is, individual, interpersonal, community, and societal). On the basis of the scientific literature, the authors engaged in consensus decision making in selecting nutrition-related determinants of health within each domain and socioecological level when creating the NHDF. The framework identifies how neighborhood food availability and access (individual/built environment) intersect with cultural norms and practices (interpersonal/sociocultural environment) to influence dietary behaviors, exposures, and risk of diet-related diseases. In addition, the NHDF shows how factors such as genetic predisposition (individual/biology), family dietary practices (interpersonal/behavioral), and food marketing policies (societal) may impact the consumption of unhealthy foods and beverages and increase chronic disease risk. Family and peer norms (interpersonal/behavior) related to breastfeeding and early childhood nutrition interact with resource-poor environments such as lack of access to preventive healthcare settings (societal/healthcare system) and low usage of federal nutrition programs (societal/behavioral), which may increase risk of poor nutrition during childhood and food insecurity. The NHDF describes the synergistic interrelationships among factors at different levels of the socioecological model that influence nutrition-related outcomes and exacerbate health disparities. The framework is a useful resource for nutrition researchers, practitioners, food industry leaders, and policymakers interested in improving diet-related health outcomes and promoting health equity in diverse populations.

The Impact of Health Inequities on Population-Based Breast Cancer Survival in a Colombian Population, 2008-2015.

OBJECTIVE: To obtain breast cancer survival estimates in Manizales, Colombia, considering socioeconomic level, health insurance regime and residential area, while adjusting for age, histology and stage at diagnosis. METHODS: Analytical cohort study based on breast cancer incident cases recorded by the Population-based Manizales Cancer Registry between 2008-2015. Patients were followed-up for 60 months. Cause-specific survival was calculated using the Kaplan-Meier method for variables of interest, with the Wilcoxon-Breslow-Gehan test for differences. Cox multivariate regression models were fitted. RESULTS: 856 breast cancer cases were included. The 5-year cause-specific survival for the entire cohort was 78.2%. It was higher in women with special/exception health insurance, high socioeconomic level, <50 years old, ductal carcinoma, and stages I and II. Residential area did not impact survival. In Cox models, the subsidized health insurance regime (HR: 4.87 vs contributory) and low socioeconomic level (HR: 2.45 vs high) were predictors of the hazard of death in women with breast cancer, adjusted for age, histology, stage and interactions age-stage and insurance-stage. A positive interaction (synergistic effect modification) between health insurance regime and stage regarding to survival was observed. CONCLUSION: Socioeconomic factors significantly contribute to the inequities in breast cancer survival, independent of the stage at diagnosis. This suggests the need for comprehensive interventions to remove barriers to accessing the health system. This research provides evidence of survival gaps mediated by certain social determinants of health and generates data on the overall performance of the Colombian health system.

The impact of telomere length on prostate cancer aggressiveness, genomic instability and health disparities.

The telomere repetitive TTAGGG motif at the ends of chromosomes, serves to preserve genomic integrity and chromosomal stability. In turn, genomic instability is a hallmark of cancer-implicating telomere disturbance. Prostate cancer (PCa) shows significant ancestral disparities, with men of African ancestry at the greatest risk for aggressive disease and associated genomic instability. Yet, no study has explored the role of telomere length (TL) with respect to ancestrally driven PCa health disparities. Patient- and technically-matched tumour-blood whole genome sequencing data for 179 ancestrally defined treatment naïve PCa patients (117 African, 62 European), we assessed for TL (blood and tumour) associations. We found shortened tumour TL to be associated with aggressive PCa presentation and elevated genomic instabilities, including percentage of genome alteration and copy number gains, in men of African ancestry. For European patients, tumour TL showed significant associations with PCa driver genes PTEN, TP53, MSH2, SETBP1 and DDX11L1, while shorter blood TL (< 3200 base pairs) and tumour TL (< 2861 base pairs) were correlated with higher risk for biochemical recurrence. Concurring with previous studies linking TL to PCa diagnosis and/or prognosis, for the first time we correlated TL differences with patient ancestry with important implications for future treatments targeting telomere dysfunction.

Burden of liver cancer mortality by county, race, and ethnicity in the USA, 2000-19: a systematic analysis of health disparities.

BACKGROUND: Understanding how specific populations are affected by liver cancer is important for identifying priorities, policies, and interventions to mitigate health risks and reduce disparities. This study aims to provide comprehensive analysis of rates and trends in liver cancer mortality for different racial and ethnic populations in the USA nationally and at the county level from 2000 to 2019. METHODS: We applied small-area estimation methods to death registration data from the US National Vital Statistics System and population data from the US National Center for Health Statistics to estimate liver cancer mortality rates by county, racial and ethnic population, and year (2000-19) in the USA. Race and ethnicity were categorised as non-Latino and non-Hispanic American Indian or Alaska Native (AIAN), non-Latino and non-Hispanic Asian or Pacific Islander (Asian), non-Latino and non-Hispanic Black (Black), Latino or Hispanic (Latino), and non-Latino and non-Hispanic White (White). Estimates were adjusted using published misclassification ratios to correct for inaccuracies in race or ethnicity as recorded on death certificates, and then age-standardised. Mortality rate estimates are presented for all county and racial and ethnic population combinations with a mean annual population greater than 1000. FINDINGS: Nationally, the age-standardised liver cancer mortality rate increased between the years 2000 (4·2 deaths per 100 000 population [95% uncertainty interval 4·1-4·3]) and 2016 (6·0 per 100 000 [5·9-6·1]), followed by a stabilisation in rates from 2016 to 2019 (6·1 per 100 000 [6·0-6·2]). Similar trends were observed across the AIAN, Black, Latino, and White populations, whereas the Asian population showed an overall decrease across the 20-year study period. Qualitatively similar trends were observed in most counties; however, the mortality rate and the rate of change varied substantially across counties, both within and across racial and ethnic populations. For the 2016-19 period, mortality continued to increase at a substantial rate in some counties even while it stabilised nationally. Nationally, the White population had the lowest mortality rate in all years, while the racial and ethnic population with the highest rate changed from the Asian population in 2000 to the AIAN population in 2019. Racial and ethnic disparities were substantial: in 2019, mortality was highest in the AIAN population (10·5 deaths per 100 000 [9·1-12·0]), notably lower for the Asian (7·5 per 100 000 [7·1-7·9]), Black (7·6 per 100 000 [7·3-7·8]), and Latino (7·7 per 100 000 [7·5-8·0]) populations, and lowest for the White population (5·5 [5·4-5·6]). These racial and ethnic disparities in mortality were prevalent throughout the country: in 2019, mortality was higher in minoritised racial and ethnic populations than in the White population living in the same county in 408 (87·7%) of 465 counties with unmasked estimates for the AIAN population, 604 (90·6%) of 667 counties for the Asian population, 1207 (81·2%) of 1486 counties for the Black population, and 1073 (73·0%) of 1469 counties for the Latino population. INTERPRETATION: Although the plateau in liver cancer mortality rates in recent years is encouraging, mortality remains too high in many locations throughout the USA, particularly for minoritised racial and ethnic populations. Addressing population-specific risk factors and differences in access to quality health care is essential for decreasing the burden and disparities in liver cancer mortality across racial and ethnic populations and locations.

Examining the impact of COVID-19 on Maori:non-Maori health inequities in Aotearoa, New Zealand: an observational study protocol.

INTRODUCTION: The COVID-19 pandemic has had both direct and indirect impacts on the health of populations worldwide. While racial/ethnic health inequities in COVID-19 infection are now well known (and ongoing), knowledge about the impact of COVID-19 pandemic management on non-COVID-19-related outcomes for Indigenous peoples is less well understood. This article presents the study protocol for the Health Research Council of New Zealand funded project 'Ma te Mohio ka Marama: Impact of COVID-19 on Maori:non-Maori inequities'. The study aims to explore changes in access to healthcare, quality of healthcare and health outcomes for Maori, the Indigenous peoples of Aotearoa New Zealand (NZ) and non-Maori during the COVID-19 outbreak period across NZ. METHODS AND ANALYSIS: This observational study is framed within a Kaupapa Maori research positioning that includes Kaupapa Maori epidemiology. National datasets will be used to report on access to healthcare, quality of healthcare and health outcomes between Maori and non-Maori during the COVID-19 pandemic in NZ. Study periods are defined as (a) prepandemic period (2015-2019), (b) first pandemic year without COVID-19 vaccines (2020) and (c) pandemic period with COVID-19 vaccines (2021 onwards). Regional and national differences between Maori and non-Maori will be explored in two phases focused on identified health priority areas for NZ including (1) mortality, cancer, long-term conditions, first 1000 days, mental health and (2) rheumatic fever. ETHICS AND DISSEMINATION: This study has ethical approval from the Auckland Health Research Ethics Committee (AHREC AH26253). An advisory group will work with the project team to disseminate the findings of this project via project-specific meetings, peer-reviewed publications and a project-specific website. The overall intention of the project is to highlight areas requiring health policy and practice interventions to address Indigenous inequities in health resulting from COVID-19 pandemic management (both historical and in the future).

Health Disparities in Young Adults: A Direct Comparison of Distress and Unmet Needs Across Cancer Centers.

PURPOSE: Information on concerns that young adults (YAs) with cancer face when receiving care outside of specialized treatment centers is needed to increase equitable care to YAs at greater risk of marginalization by the health care system. The current study compared distress and unmet needs at the time of clinic visit between YAs receiving care from three different cancer clinics: (1) a National Cancer Institute-designated center, (2) a community-based clinic, and (3) a county hospital outpatient clinic. METHODS: The Adolescent and Young Adult Psycho-Oncology Screening Tool (AYA-POST) was administered to measure distress and cancer-related concerns of YAs in active treatment. A one-way analysis of variance (ANOVA) compared distress scores by treatment site. A Fisher's exact test compared the number of participants endorsing each item on the Needs Assessment Checklist from each site. A simple linear regression determined the association between distress and number of items endorsed on the Needs Assessment Checklist. RESULTS: Ninety-seven participants completed the AYA-POST, endorsing, on average, 11 concerns. Fisher's exact test showed significant differences between sites in the proportion of participants endorsing eight items: boredom (P < .001), eating/appetite (P < .001), nausea/vomiting (P < .001), financial concern (P = .002), hopelessness/helplessness (P = .03), confidentiality (P = .04), sibling concern (P = .04), and insurance (P = .05). The simple linear regression model was significant (F(1, 94) = 39.772, P < .001, R2 = 0.297), indicating the number of unmet needs accounted for almost 30% of the variance in distress. The one-way ANOVA was not significant (F(2, 93) = 1.34, P = .267). CONCLUSION: Social determinants of health can influence the number and type of unmet needs experienced, affecting distress and other outcomes and underscoring the importance of timely, effective, age-appropriate screening and intervention for distress and unmet needs in YAs with cancer.

Racial iniquity in mortality from cervical cancer in Brazil: a time trend study from 2002 to 2021. / Iniquidade racial na mortalidade por câncer de colo de útero no Brasil: estudo de séries temporais de 2002 a 2021.

This ecological study examined time series, from 2002 to 20121, of age-adjusted coefficients of cervical cancer mortality, in Brazil, in women aged 20 years or more, by race. The information sources were Brazil's mortality information system (Sistema de Informação sobre Mortalidade - SIM) and the official bureau of statistics (Instituto Brasileiro de Geografia e Estatística - IBGE). Annual changes in age-adjusted mortality rates were calculated using the Prais-Winsten linear regression method. Black women die more and the rate is decreasing less. Racial inequality has increased over the years. In 2002, there were 0.08 more deaths per 100,000 women in the black population than among white women; in 2021, the number was one death. Health policymaking should consider racial differences in the implementation of strategies and goals.

O objetivo desse artigo é analisar séries temporais da mortalidade por câncer de colo do útero segundo raça/cor no Brasil de 2002 a 2021. Estudo ecológico de séries temporais com dados do Sistema de Informação sobre Mortalidade e informações populacionais do IBGE. Variações anuais das taxas de mortalidade ajustadas por idade de mulheres de 20 anos ou mais foram estimadas pelo modelo de regressão linear simples com correção de Prais-Winsten. Foram registrados 133.429 óbitos por câncer de colo de útero, destes, 51,2% foram de mulheres negras. As mulheres negras morrem mais e têm menor queda do coeficiente. Houve aumento da desigualdade racial ao longo dos anos. Em 2002, ocorriam 0,08 óbitos/100 mil mulheres a mais na população negra comparada com a população branca; em 2021 esse número é de aproximadamente 1 óbito. Para a elaboração de políticas de saúde da mulher devem ser consideradas as diferenças raciais na implementação de estratégias e metas.

Social determinants of health and health inequities in breast cancer screening: a scoping review.

Introduction: This scoping review aims to highlight key social determinants of health associated with breast cancer screening behavior in United States women aged ≥40 years old, identify public and private databases with SDOH data at city, state, and national levels, and share lessons learned from United States based observational studies in addressing SDOH in underserved women influencing breast cancer screening behaviors. Methods: The Arksey and O'Malley York methodology was used as guidance for this review: (1) identifying research questions; (2) searching for relevant studies; (3) selecting studies relevant to the research questions; (4) charting the data; and (5) collating, summarizing, and reporting results. Results: The 72 included studies were published between 2013 and 2023. Among the various SDOH identified, those related to socioeconomic status (n = 96) exhibited the highest frequency. The Health Care Access and Quality category was reported in the highest number of studies (n = 44; 61%), showing its statistical significance in relation to access to mammography. Insurance status was the most reported sub-categorical factor of Health Care Access and Quality. Discussion: Results may inform future evidence-based interventions aiming to address the underlying factors contributing to low screening rates for breast cancer in the United States.

Health inequities and societal costs for patients with fibromyalgia and their spouses: a Danish cohort study.

OBJECTIVE: To assess the burden of illness of people with fibromyalgia (FM) and their spouses compared with selected match populations in Denmark. METHODS: Population-based, cohort case-control study using data from Danish registries from 1994 to 2021. Individuals with an FM diagnosis were identified from the National Patient Register (2008-2019) and randomly matched to a 1:4 general population comparator. Spouses or persons co-living with subjects with FM at the time of diagnosis were compared with matched comparator spouses. Healthcare and societal costs, socioeconomic status and occurrence of comorbidities were evaluated for subjects with FM, spouses and controls. RESULTS: 9712 subjects with FM (94.9% females, mean age 50 years) and 5946 spouses were included. At year of diagnosis, subjects with FM had significantly more comorbidities compared with controls, including significantly more comorbid rheumatic disorders. The highest risk at the time of FM diagnosis was a comorbid diagnosis of ankylosing spondylitis (OR 7.0, 95% CI 4.9 to 10.0). Significantly more comorbidities were also observed in spouses. Subjects with FM and spouses had higher healthcare and public transfer costs and lower income from employment at all timepoints. Loss of income from employment in subjects with FM occurred years before establishment of the FM diagnosis. The employment rate after diagnosis was 22%. 10 years after the FM diagnosis, 50% received disability pension as compared with 11% of matched controls. The observed net average increased societal cost for subjects with FM amounted to €27 193 per patient-year after diagnosis. CONCLUSION: FM has major health and socioeconomic consequences for patients, their partners and society and call for improved healthcare strategies matching patients' needs.

A longitudinal analysis of health inequalities from adolescence to young adulthood and their underlying causes.

Research suggests that children of low-educated parents face greater health burdens during the passage from adolescence to young adulthood, as they are more likely to become low-educated themselves, establish behavioural and psychosocial disadvantages, or being exposed to unhealthy working conditions. However, studies examining the development and drivers of health inequalities during this particular life stage are limited in number and have produced varied results. This study investigates trajectories of self-rated health and overweight from 14 to 25 years of age, stratified by parental education, and explores the role of potential mediators (educational achievement, health behaviours, psychosocial factors, working conditions). We rely on prospective cohort data from the National Educational Panel Study (NEPS), a representative sample of 14,981 German ninth graders interviewed yearly from 2011 to 2021 (n = 90,096 person-years). First, we estimated random-effects growth curves for self-rated health and overweight over participants' age and calculated the average marginal effect of high versus low parental education. Second, a series of simulation-based mediation analyses were performed to test how much of health inequalities were explained by children's educational attainment (years of school education, years in university), health behaviours (smoking, alcohol, physical inactivity), psychosocial factors (number of grade repetitions, years in unemployment, chronic stress, self-esteem) and working conditions (physical and psychosocial job demands). We accounted for potential confounding by controlling for age, sex, migration background, residential area, household composition, and interview mode. Results show that higher parental education was related to higher self-rated health and lower probabilities of being overweight. Interaction between parental education and age indicated that, after some equalisation in late adolescence, health inequalities increased in young adulthood. Furthermore, educational attainment, health behaviours, psychosocial factors, and early-career working conditions played a significant role in mediating health inequalities. Of the variables examined, the level of school education and years spent in university were particular strong mediating factors. School education accounted for around one-third of the inequalities in self-rated health and one-fifth of the differences in overweight among individuals. Results support the idea that the transition to adulthood is a sensitive period in life and that early socio-economic adversity increases the likelihood to accumulate health disadvantages in multiple dimensions. In Germany, a country with comparatively low educational mobility, intergenerational continuities in class location seem to play a key role in the explanation of health inequalities in youth.

Health inequalities for people with learning disabilities: why it matters and what emergency physicians need to know.

People with learning disabilities die on average 16 years earlier than the general population in England. They are a vulnerable group and may have unhealthy lifestyles and multimorbidity that lead to poor health outcomes. Worryingly, premature deaths are also more common and these often have contributory healthcare causes. This may be a result of staff lacking awareness, expertise and experience managing people with learning disabilities, the lack of reasonable adjustments, or discriminatory attitudes. Other issues include polypharmacy and inappropriate prescribing of sedatives, inappropriate use of do not resuscitate orders, and diagnostic overshadowing leading to delayed or misdiagnoses. Emergency physicians need to be aware of subtle or atypical presentations of illnesses such as sepsis. Carers and family can be vital informants, helping clinicians to interpret subtle signs and aid communication with people with learning disabilities. One simple approach to reasonable adjustments, as required by law, is the TEACH mnemonic: people with learning disabilities need more time (T), in a conducive environment (E), with clinicians approaching them with the right attitude (A) and an open mind. Good communication (C) is essential and clinicians must make every attempt to understand their patients and to be understood by their patients. Finally clinicians need to consider what 'help' (H) the patient and their carers or family needs. With the right approach, time and environment, emergency physicians can optimise the care delivered to people with learning disabilities to address their needs.

Quantifying the Value of Reduced Health Disparities: Low-Dose Computed Tomography Lung Cancer Screening of High-Risk Individuals Within the United States.

OBJECTIVE: This study aimed to measure the value of increasing lung cancer screening rates for high-risk individuals and its impact on health disparities. METHODS: The model estimated changes in health economic outcomes if low-dose computed tomography screening increased from current to 100% compliance, following clinical guidelines. Current low-dose computed tomography screening rates were estimated by income, education, and race, using 2017-2019 Behavioral Risk Factor Surveillance System data. The model contained a decision tree module to segment the population by screening outcomes and a Markov chain module to estimate cancer progression over time. Model parameters included information on survival, quality of life, and costs related to cancer diagnosis, treatment, and adverse events. Distributional cost-effectiveness analysis estimated the net monetary value from reduced health disparities-measured using quality-adjusted life expectancy-across income, education, and race groups. Outcomes were assessed over 30 years. RESULTS: Lung cancer screening eligibility using US Preventive Services Task Force guidelines was higher for individuals with income <$15 000 (47.2%) and without a high-school education (46.1%) than individuals with income >$50 000 (16.6%) and with a college degree (13.5%), respectively. Increasing lung cancer screening to 100% compliance was cost-effective ($64 654 per quality-adjusted life-year) and produced economic value by up to $560 per person ($182.1 billion for United States overall). Up to 32.2% of the value was due to reductions in health disparities. CONCLUSIONS: Significant value in increasing lung cancer screening rates derived from reducing health disparities. Policy makers and clinicians may not be appropriately prioritizing cancer screening if value from reducing health disparities is unconsidered.

Maternal and Perinatal Health Disparities Among Middle Eastern and North African Women and Children in the United States.

INTRODUCTION: Few studies have evaluated the health of Middle Eastern and North African (MENA) women and children in the United States. Objectives were to determine the odds of well-visits, preventive behaviors during pregnancy, and low birthweight among foreign-born non-Hispanic MENA women and children compared to their US- and foreign-born non-Hispanic White counterparts after adjusting for covariates (hereafter, reported as MENA and White). METHODS: We analyzed 2000-2018 National Health Interview Survey data (411,709 women, 311,961 children). Outcomes included well-woman visits (past 12 months); dentist visits (past 6 months) and current smoking among pregnant women; and low, moderately low, and very low birthweight among children. Covariates included age, family income, and health insurance for children. Education and marital status were also evaluated among women. RESULTS: Over half (53.4%) of foreign-born MENA women were of childbearing age (ages 18-45) compared to 47.7% US-born and 43.2% foreign-born White women. The odds of completing a well-women visit were 0.73 times lower (95% CI = 0.38-0.89) among foreign-born MENA women compared to US-born White women after adjusting for age, education, and marital status. There was no statistically significant difference in dental visits between groups. No foreign-born MENA pregnant women reported current smoking. Foreign-born MENA children had higher odds of low (OR = 1.65; 95% CI = 1.16-2.35) and moderately low birthweight (OR = 1.78; 95% CI = 1.19-2.66) compared to US-born White children in adjusted models. DISCUSSION: MENA women and children are classified as White by the federal government. Our results highlight that the health of foreign-born MENA women and children differ from their White counterparts.

Using the Social Vulnerability Index to Analyze Statewide Health Disparities in Cholecystectomy.

INTRODUCTION: Addressing the effects of social determinants of health in surgery has become a national priority. We evaluated the utility of the Social Vulnerability Index (SVI) in determining the likelihood of receiving cholecystectomy for cholecystitis in Texas. METHODS: A retrospective study of adults with cholecystitis in the Texas Hospital Inpatient Discharge Public Use Data File and Texas Outpatient Surgical and Radiological Procedure Data Public Use Data File from 2016 to 2019. Patients were stratified into SVI quartiles, with the lowest quartile as low vulnerability, the middle two as average vulnerability, and the highest as high vulnerability. The relative risk (RR) of undergoing surgery was calculated using average vulnerability as the reference category and subgroup sensitivity analyses. RESULTS: A total of 67,548 cases were assessed, of which 48,603 (72.0%) had surgery. Compared with the average SVI groups, the low vulnerability groups were 21% more likely to undergo cholecystectomy (RR = 1.21, 95% confidence interval [CI] 1.18-1.24), whereas the high vulnerability groups were 9% less likely to undergo cholecystectomy (RR = 0.91, 95% CI 0.88-0.93). The adjusted model showed similar results (RR = 1.05, 95% CI 1.04-1.06 and RR = 0.97, 95% CI 0.96-0.99, for low and high vulnerability groups, respectively). These results remained significant after stratifying for age, sex, ethnicity, and insurance status. However, the differences between low, average, and high vulnerability groups diminished in rural settings, with lower surgery rates in all groups. CONCLUSIONS: Patients with higher SVI were less likely to receive an elective cholecystectomy. SVI is an effective method of identifying social determinants impacting access to and receipt of surgical care.

Isolating the Drivers of Racial Inequities in Prostate Cancer Treatment.

BACKGROUND: Black individuals in the United States are less likely than White individuals to receive curative therapies despite a 2-fold higher risk of prostate cancer death. While research has described treatment inequities, few studies have investigated underlying causes. METHODS: We analyzed a cohort of 40,137 Medicare beneficiaries (66 and older) linked to the Surveillance Epidemiology and End Results (SEER) cancer registry who had clinically significant, non-metastatic (cT1-4N0M0, grade group 2-5) prostate cancer (diagnosed 2010-2015). Using the Kitagawa-Oaxaca-Blinder decomposition, we assessed the contributions of patient health and health care delivery on the racial difference in localized prostate cancer treatments (radical prostatectomy or radiation). Patient health consisted of comorbid diagnoses, tumor characteristics, SEER site, diagnosis year, and age. Health care delivery was captured as a prediction model with these health variables as predictors of treatment, reflecting current treatment patterns. RESULTS: A total of 72.1% and 78.6% of Black and White patients received definitive treatment, respectively, a difference of 6.5 percentage points. An estimated 15% [95% confidence interval (CI): 6-24] of this treatment difference was explained by measured differences in patient health, leaving the remaining estimated 85% (95% CI: 74-94) attributable to a potentially broad range of health care delivery factors. Limitations included insufficient data to explore how specific health care delivery factors, including structural racism and social determinants, impact differential treatment. CONCLUSIONS: Our results show the inadequacy of patient health differences as an explanation of the treatment inequity. IMPACT: Investing in studies and interventions that support equitable health care delivery for Black individuals with prostate cancer will contribute to improved outcomes.

It Takes a Village: An Interdisciplinary Approach to Preparing Internal Medicine Residents to Care for Patients at the Intersection of Women's Health, Gender-Affirming Care, and Health Disparities.

Objective: To create an interdisciplinary curriculum to teach key topics at the intersection of women's health, gender-affirming care, and health disparities to internal medicine (IM) residents. Materials and Methods: A core team of faculty from IM, Obstetrics and Gynecology, and Surgery partnered with faculty and fellows from other disciplines and with community experts to design and deliver the curriculum. The resulting curriculum consisted of themed half-day modules, each consisting of three to four inter-related topics, updated and repeated on an ∼3-year cycle. Health equity was a focus of all topics. Module delivery used diverse interactive learning strategies. Modules have been presented to ∼175 residents annually, beginning in 2015. To assess the curriculum, we used formative evaluation methods, using primarily anonymous, electronic surveys, and collected quantitative and qualitative data. Most surveys assessed resident learning by quantifying residents' self-reported comfort with skills taught in the module pre- and postsession. Results: Of 131 residents who completed an evaluation in 2022/23, 121 (90%) "somewhat" or "strongly" agreed with their readiness to perform a range of skills taught in the module. In all previous years where pre- and postsurveys were used to evaluate modules, we observed a consistent meaningful increase in the proportion of residents reporting high levels of comfort with the material. Residents particularly valued interactive teaching methods, and direct learning from community members and peers. Conclusion: Our interdisciplinary curriculum was feasible, valued by trainees, and increased resident learning. The curriculum provides a template to address equity issues across a spectrum of women's and gender-affirming care conditions that can be used by other institutions in implementing similar curricula.

Mining the health disparities and minority health bibliome: A computational scoping review and gap analysis of 200,000+ articles.

Without comprehensive examination of available literature on health disparities and minority health (HDMH), the field is left vulnerable to disproportionately focus on specific populations or conditions, curtailing our ability to fully advance health equity. Using scalable open-source methods, we conducted a computational scoping review of more than 200,000 articles to investigate major populations, conditions, and themes as well as notable gaps. We also compared trends in studied conditions to their relative prevalence using insurance claims (42 million Americans). HDMH publications represent 1% of articles in Medical Literature Analysis and Retrieval System Online (MEDLINE). Most studies are observational in nature, although randomized trial reporting has increased fivefold in the past 20 years. Half of HDMH articles concentrate on only three disease groups (cancer, mental health, and endocrine/metabolic disorders), while hearing, vision, and skin-related conditions are among the least well represented despite substantial prevalence. To support further investigation, we present HDMH Monitor, an interactive dashboard and repository generated from the HDMH bibliome.

Bridging Health Disparities: a Genomics and Transcriptomics Analysis by Race in Prostate Cancer.

As the era of cancer genomics expands, disproportionate rates of prostate cancer incidence and mortality by race have demonstrated increasing relevance in clinical settings. While Black men are most particularly affected, as data has historically shown, the opposite is observed for Asian men, thus creating a basis for exploring genomic pathways potentially involved in mediating these opposing trends. Studies on racial differences are limited by sample size, but recent expanding collaborations between research institutions may improve these imbalances to enhance investigations on health disparities from the genomics front. In this study, we performed a race genomics analysis using GENIE v11, released in January 2022, to investigate mutation and copy number frequencies of select genes in both primary and metastatic patient tumor samples. Further, we investigate the TCGA race cohort to conduct an ancestry analysis and to identify differentially expressed genes highly upregulated in one race and subsequently downregulated in another. Our findings highlight pathway-oriented genetic mutation frequencies characterized by race, and further, we identify candidate gene transcripts that have differential expression between Black and Asian men.
