Allostatic load burden and racial disparities in mortality

Taking action to achieve health equity and eliminate healthcare disparities within acute care surgery

Addressing disparities is crucial for enhancing population health, ensuring health security, and fostering resilient health systems. Disparities in acute care surgery (trauma, emergency general surgery, and surgical critical care) have been well documented and the magnitude of inequities demand an intentional, organized, and effective response. As part of its commitment to achieve high-quality, equitable care in all aspects of acute care surgery, the American Association for the Surgery of Trauma convened an expert panel at its eigty-second annual meeting in September 2023 to discuss how to take action to work towards health equity in acute care surgery practice. The panel discussion framed contemporary disparities in the context of historic and political injustices, then identified targets for interventions and potential action items in health system structure, health policy, the surgical workforce, institutional operations and quality efforts. We offer a four-pronged approach to address health inequities: identify, reduce, eliminate, and heal disparities, with the goal of building a healthcare system that achieves equity and justice for all.

Chronic Work Discrimination, Allostatic Load, and HbA1c in Older Workers

BACKGROUND AND OBJECTIVE

Work discrimination is an important public health problem with consequences for health. This study examined the effect of chronic work discrimination on 4-year changes in HbA1c, as a reflection of glucose control and type 2 diabetes risk in older workers and assessed whether allostatic load (AL) affected the strength of this association.

RESEARCH DESIGN AND METHODS

We used Health and Retirement Study data (2010-2016, n = 3,246). Conditional change multinomial logistic regression examined the association between chronic work discrimination, high AL (4 or more out of 8 high-risk biomarkers), and HbA1c, while accounting for relevant covariates.

RESULTS

Black participants had the highest rates of baseline (22.7%) and follow-up (28%) HbA1c levels, AL (38%), and chronic work discrimination (39%; p < .01). Severe chronic work discrimination was associated with elevated HbA1c (relative risk ratio [RRR] = 1.61, 95% confidence interval [CI] = 1.07, 2.43). AL was associated with elevated HbA1c (RRR = 1.49, 95% CI = 1.04, 2.14). Relative to White participants, Hispanic (RRR = 1.52, 95% CI = 1.07, 2.16, RRR = 1.81, 95% CI = 1.051, 3.12), and Black (RRR = 2.42, 95% CI = 1.82, 3.23; RRR = 3.00, 95% CI = 1.97, 4.56) participants had an increased risk of intermediate and elevated HbA1c, respectively. Among those with long job tenure (≥5 years), both moderate (RRR = 1.81, 95% CI = 1.11, 2.96) and severe (RRR = 1.90, 95% CI = 1.15, 3.12) chronic work discrimination was associated with elevated HbA1c.

DISCUSSION AND IMPLICATIONS

Chronic work discrimination was associated with HbA1c; however, no moderating effects of AL were observed. Findings underscore a need for organizational and public health measures to establish strong anti-discrimination laws in the workplace to improve the work environment of older workers and reduce diabetes risk.

Obtaining the Most Accurate, Explainable Model for Predicting Chronic Obstructive Pulmonary Disease: Triangulation of Multiple Linear Regression and Machine Learning Methods

BACKGROUND

Lung disease is a severe problem in the United States. Despite the decreasing rates of cigarette smoking, chronic obstructive pulmonary disease (COPD) continues to be a health burden in the United States. In this paper, we focus on COPD in the United States from 2016 to 2019.

OBJECTIVE

We gathered a diverse set of non-personally identifiable information from public data sources to better understand and predict COPD rates at the core-based statistical area (CBSA) level in the United States. Our objective was to compare linear models with machine learning models to obtain the most accurate and interpretable model of COPD.

METHODS

We integrated non-personally identifiable information from multiple Centers for Disease Control and Prevention sources and used them to analyze COPD with different types of methods. We included cigarette smoking, a well-known contributing factor, and race/ethnicity because health disparities among different races and ethnicities in the United States are also well known. The models also included the air quality index, education, employment, and economic variables. We fitted models with both multiple linear regression and machine learning methods.

RESULTS

The most accurate multiple linear regression model has variance explained of 81.1%, mean absolute error of 0.591, and symmetric mean absolute percentage error of 9.666. The most accurate machine learning model has variance explained of 85.7%, mean absolute error of 0.456, and symmetric mean absolute percentage error of 6.956. Overall, cigarette smoking and household income are the strongest predictor variables. Moderately strong predictors include education level and unemployment level, as well as American Indian or Alaska Native, Black, and Hispanic population percentages, all measured at the CBSA level.

CONCLUSIONS

This research highlights the importance of using diverse data sources as well as multiple methods to understand and predict COPD. The most accurate model was a gradient boosted tree, which captured nonlinearities in a model whose accuracy is superior to the best multiple linear regression. Our interpretable models suggest ways that individual predictor variables can be used in tailored interventions aimed at decreasing COPD rates in specific demographic and ethnographic communities. Gaps in understanding the health impacts of poor air quality, particularly in relation to climate change, suggest a need for further research to design interventions and improve public health.

Relationships among race, ethnicity, and gender and whole health among U.S. veterans

Racial, ethnic, and gender health care disparities in the United States are well-documented and stretch across the lifespan. Even in large integrated health care systems such as Veteran Health Administration, which are designed to provide equality in care, social and economic disparities persist, and limit patients' achievement of health goals across multiple domains. We explore Veterans' Whole Health priorities among Veteran demographic groups. Participants who were enrolling in Veteran Health Administration provided demographics and Whole Health priorities using eScreening, a web-based self-assessment tool. Veterans had similar health care goals regardless of demographic characteristics but differences were noted in current health appraisals. Non-White and women Veterans reported worse health-relevant functioning. Black Veterans were more likely to endorse a low rating for their personal development/relationships. Multiracial Veterans were more likely to endorse a low rating of their surroundings. Asian Veterans were less likely to provide a high rating of their surroundings. Women Veterans reported lower appraisals for body and personal development but higher appraisals of professional care. Results indicated that demographic factors such as race and gender, and to a lesser extent ethnicity, were associated with health disparities. The Whole Health model provides a holistic framework for addressing these disparities. These findings may inform more culturally sensitive care and enhance Veteran Health Administration equal access initiatives. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Addressing the Harms of Structural Racism on Health in Incarcerated Youth Through Improved Nutrition and Exercise Programs

Every year, hundreds of thousands of youth across the country enter the juvenile legal system. A significantly disproportionate number of them are youth of color. While youth arrests have declined over the past several decades, racial disparities have increased and persist at every stage of the system. Many youth of color enter the juvenile legal system with a history of trauma and stress that compromises their health and well-being. Arrest, prosecution, and incarceration exacerbate these poor health outcomes. This paper examines several of the health impacts of structural racism in the policing and incarceration of youth of color. The paper begins by highlighting some of the most pressing social determinants of adolescent health and then considers how youth detention and incarceration contribute to unhealthy weight, hypertension, diabetes, and cardiovascular disease through unhealthy food environments, limited physical activity, and the added stress of the incarceration setting. This paper adds to the existing literature on the harms of youth detention and advocates for harms elimination strategies grounded in a public health approach to public safety and community-based alternatives to detention. For those youth who will remain in detention, the authors offer suggestions to reduce harms and improve the health of systems-involved youth, including opportunities for research.

Racial Disparities in COVID-19 Severity Are Partially Mediated by Chronic Stress-Evidence from a Large Integrated Healthcare System

BACKGROUND

Racial and ethnic minorities have experienced a disproportionate burden of severe COVID-19. Whether chronic stress, also disproportionately experienced by racial and ethnic minorities, explains this excess risk is unknown.

METHODS

We identified 9577 adults (≥ 18 years) diagnosed with COVID-19 from January 1, 2020, through September 30, 2021, enrolled in Kaiser Permanente Georgia (KPGA) with complete biomarker data. Self-reported race (Black or White) was defined from electronic medical records. Chronic stress, defined as allostatic load (AL), a composite score (scale 0-7) based on seven cardio-metabolic biomarkers, was categorized as below (low AL) or above (high AL) the median. Severe COVID-19 was defined as hospitalization or mortality within 30 days of COVID-19 diagnosis. The association between race, AL, and severe COVID-19 was assessed using multivariable Poisson regression. The mediating effect of AL was assessed using the Valeri and VanderWeele method. All results were expressed as risk ratios (RRs) with 95% confidence intervals.

RESULTS

Overall, Black (vs. White) KPGA members had an 18% excess risk of AL (RR: 1.18, 95%CI: 1.14-1.23) and a 24% excess risk of severe COVID-19 (RR: 1.24, 95%CI: 1.12, 1.37). AL explained 23% of the Black-White disparities in severe COVID-19.

CONCLUSIONS

In our study, chronic stress, characterized by AL, partially mediated Black-White disparities in severe COVID-19 outcomes.

Looking Upstream to Understand Race/Ethnicity as a Moderator for Poststroke Neuroinflammation and a Social Determinant for Poststroke Aphasia Outcomes

INTRODUCTION

Over the past decade, the stroke literature has begun to acknowledge and explore explanations for longstanding racial/ethnic differences in stroke outcomes. Poststroke cognitive impairment (PSCI) and poststroke aphasia are two such negative poststroke outcomes where racial/ethnic differences exist. Physiological differences, such as stroke type and lesion size, have been used to partially explain the variation in PSCI and aphasia. However, there is some evidence, although limited, that suggests neuroinflammatory processes as part of allostatic load may be a key contributor to the observed disparities.

METHOD

In this tutorial, we explore the influence of race differences in inflammation on poststroke cognitive outcomes. We suggest lifetime stress and other external determinants of health such as neighborhood environment and discriminatory practices through "weathering" explain differences in inflammation. While using an allostatic load framework, we explore the literature focusing specifically on the role of neuroinflammation on poststroke outcomes.

CONCLUSIONS

Examination of the immune response poststroke provides a foundation for understanding the mechanisms of PSCI and poststroke aphasia and the potential contributions of neuroinflammatory processes on poststroke cognitive outcomes. Furthermore, understanding of racial differences in those processes may contribute to a better understanding of racial disparities in general stroke outcomes as well as poststroke aphasia.

Subsidized Versus Unsubsidized Senior Housing Communities in PA: A Window on Variation in Health, Function, and Access to Services in Old Age

Introduction: Independent Living residences for older adults can be divided into two categories and require better definitions for research purposes; the purpose of this manuscript is to provide those definitions and explore variation in provided services and resident characteristics: (a) Subsidized age-based housing (55+) (Department of Housing and Urban Development (HUD) housing units for low-income adults), and (b) non-subsidized age-based housing. Methods: Residents in the two settings were compared: 37 subsidized locations (p = 289 residents) and 19 non-subsidized (p = 208). Aging support services in each housing type were quantified. Results: Subsidized residents are more likely to be female (84.6% vs. 70.2%, p = .0002) and have fair-poor health (36.5% vs. 12.5%, p < .0001), frequent pain (28.4% vs. 12.8%, p < .0001), and fair-poor mobility (37.5% vs. 23.5%, p = .0298). Non-subsidized locations are more likely to offer support services; on average, residents are older (mean age 83vs. 75; p < .0001) and white (97.6% vs. 69.2%, p < .0001). Conclusion: Significant differences exist between populations living in subsidized and non-subsidized housing, suggesting the effect of cumulative disadvantage over the lifespan; populations in poorer health have access to fewer services. Research is needed to explore generalizability on a national level.

Allostatic load in the US general population: Race and educational intersection

Objectives

Educational attainment is a protective factor against poor health, but high educational attainment has a weaker effect on black people than on white people; this pattern has been called marginalization-related diminished returns (MDRs). Using a national sample of white people and black people 25 years and above, this study estimates the association between high educational attainment and allostatic load between black people and white people, and within each group.

Study design

This cross-sectional study uses data from the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2016, including 2761 black people and 7058 white people. The outcome variable of interest was the Allostatic Load Scale (AL). We created the allostatic load scale by using 8 biomarkers, then created a binary variable (if ALS≥4 as 1 and ALS<4 as 0) to present elevated AL.

Methods

We used several weighted modified Poisson regression models controlling for educational attainment (a predictor) and race (a moderator variable), age, sex, and marital status. We also controlled the models for smoking and drinking status as health behavior variables. As a sensitivity analysis, we ran several sets of regression analysis using the AL scale as a continuous outcome variable.

Results

We found an inverse association between AL and educational attainment. The interaction between race and education has resulted in an inverse association between AL and educational attainment, with a weaker association in black people than in white people. We found similar findings by running regression models with AL as a continuous variable.

Conclusions

We observed a weaker association between educational attainment and AL in black people than in white people, suggesting that educational attainment has more robust protection against allostatic load for white people than black people.

Black Mothers' Concern for Their Children as a Measure of Vicarious Racism-Related Vigilance and Allostatic Load

This study investigates the relationship between allostatic load and a novel form of altruistic racism-related fear, or concern for how racism might harm another, which we term vicarious racism-related vigilance. Using a subsample of Black mothers from the African American Women's Heart & Health Study (N = 140), which includes detailed health and survey data on a community sample of Black women in the San Francisco Bay Area, this study investigates the relationship between Black mothers' experiences with racism-related vigilance as it relates to their children and allostatic load-a multisystem metric of underlying health across multiple biological systems. Findings indicate that vicarious racism-related vigilance was positively associated with allostatic load (i.e., worse health). Findings highlight the salience of vicarious racism-related vigilance for the health of Black mothers, underscoring how intersections between race, gender, and parenthood result in susceptibility to unique forms of health-harming stress.

Social Determinants of Cancer Disparities

Cancer is a major public health issue that is associated with significant morbidity and mortality across the globe. At its root, cancer represents a genetic aberration, but socioeconomic, environmental, and geographic factors contribute to different cancer outcomes for selected population subsets. The disparities in the delivery of healthcare affect all aspects of cancer management from early prevention to end-of-life care. In an effort to address the inequality in the delivery of healthcare among socioeconomically disadvantaged populations, the World Health Organization defined social determinants of health (SDOH) as conditions in which people are born, live, work, and age. These factors play a significant role in the disproportionate cancer burden among different population groups. SDOH are associated with disparities in risk factor burden, screening modalities, diagnostic testing, treatment options, and quality of life of patients with cancer. The purpose of this article is to describe a more holistic and integrated approach to patients with cancer and address the disparities that are derived from their socioeconomic background.

Effect of neighborhood deprivation index on breast cancer survival in the United States

PURPOSE

To analyze the association between the Neighborhood Deprivation Index (NDI) and clinical outcomes of locoregional breast cancer (BC).

METHODS

Surveillance, Epidemiology and End Results (SEER) database is queried to evaluate overall survival (OS) and disease-specific survival (DSS) of early- stage BC patients diagnosed between 2010 and 2016. Cox multivariate regression was performed to measure the association between NDI (Quintiles corresponding to most deprivation (Q1), above average deprivation (Q2), average deprivation (Q3), below average deprivation (Q4), least deprivation (Q5)) and OS/DSS.

RESULTS

Of the 88,572 locoregional BC patients, 27.4% (n = 24,307) were in the Q1 quintile, 26.5% (n = 23,447) were in the Q3 quintile, 17% (n = 15,035) were in the Q2 quintile, 13.5% (n = 11,945) were in the Q4 quintile, and 15.6% (n = 13,838) were in the Q5 quintile. There was a predominance of racial minorities in the Q1 and Q2 quintiles with Black women being 13-15% and Hispanic women being 15% compared to only 8% Black women and 6% Hispanic women in the Q5 quintile (p < 0.001). In multivariate analysis, in the overall cohort, those who live in Q2 and Q1 quintile have inferior OS and DSS compared to those who live in Q5 quintile (OS:- Q2: Hazard Ratio (HR) 1.28, Q1: HR 1.2; DSS:- Q2: HR 1.33, Q1: HR 1.25, all p < 0.001).

CONCLUSION

Locoregional BC patients from areas with worse NDI have poor OS and DSS. Investments to improve the socioeconomic status of areas with high deprivation may help to reduce healthcare disparities and improve breast cancer outcomes.

The heart of Detroit study: a window into urban middle-aged and older African Americans' daily lives to understand psychosocial determinants of cardiovascular disease risk

BACKGROUND

Cardiovascular disease disproportionately affects African Americans. Psychosocial factors, including the experience of and emotional reactivity to racism and interpersonal stressors, contribute to the etiology and progression of cardiovascular disease through effects on health behaviors, stress-responsive neuroendocrine axes, and immune processes. The full pathway and complexities of these associations remain underexamined in African Americans. The Heart of Detroit Study aims to identify and model the biopsychosocial pathways that influence cardiovascular disease risk in a sample of urban middle-aged and older African American adults.

METHODS

The proposed sample will be composed of 500 African American adults between the ages of 55 and 75 from the Detroit urban area. This longitudinal study will consist of two waves of data collection, two years apart. Biomarkers of stress, inflammation, and cardiovascular surrogate endpoints (i.e., heart rate variability and blood pressure) will be collected at each wave. Ecological momentary assessments will characterize momentary and daily experiences of stress, affect, and health behaviors during the first wave. A proposed subsample of 60 individuals will also complete an in-depth qualitative interview to contextualize quantitative results. The central hypothesis of this project is that interpersonal stressors predict poor cardiovascular outcomes, cumulative physiological stress, poor sleep, and inflammation by altering daily affect, daily health behaviors, and daily physiological stress.

DISCUSSION

This study will provide insight into the biopsychosocial pathways through which experiences of stress and discrimination increase cardiovascular disease risk over micro and macro time scales among urban African American adults. Its discoveries will guide the design of future contextualized, time-sensitive, and culturally tailored behavioral interventions to reduce racial disparities in cardiovascular disease risk.

The Modifying Role of Resilience on Allostatic Load and Cardiovascular Disease Risk in the Jackson Heart Study

We examined whether resilience modified associations between allostatic load (AL), a physiological indicator of coping with repeated stressors, and cardiovascular disease (CVD) among 2758 African Americans in the Jackson Heart Study. Baseline AL was quantified using biological measures of metabolic, cardiovascular, and immune markers. We constructed a multidimensional resilience measure using validated questionnaires for social support, social networks, religious experiences, and optimism. Participants were followed until 2016 for stroke, coronary heart disease (CHD), and heart failure (HF). We used multivariable-adjusted, sex-stratified Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between dichotomous AL and CVD. High AL was associated with CHD among women (HR = 1.73, 95% CI = 1.00, 2.99) and HF among women (HR = 1.52, 95% CI = 0.98, 2.37) and men (HR = 2.17, 95% CI = 1.28, 3.68). Among women, resilience did not modify the AL-CVD relationship. Among men, we observed higher stroke risk among men with low resilience (HR = 2.21, 95% CI = 0.94, 5.22) and no association among those with high resilience. Counterintuitively, high AL was associated with greater HF (HR = 5.80, 95% CI = 2.32, 14.47) in the subgroup of men with high resilience. Future studies addressing different facets of resilience are needed to elucidate underlying mechanisms for CVD prevention among African Americans.

Investigating the association between educational attainment and allostatic load with risk of cancer mortality among African American women

BACKGROUND

African American (AA) women navigate the world with multiple intersecting marginalized identities. Accordingly, AA women have higher cumulative stress burden or allostatic load (AL) compared to other women. Studies suggest that AA women with a college degree or higher have lower AL than AA women with less than a high school diploma. We examined the joint effect of educational attainment and AL status with long-term risk of cancer mortality, and whether education moderated the association between AL and cancer mortality.

METHODS

We performed a retrospective analysis among 4,677 AA women within the National Health and Nutrition Examination Survey (NHANES) from 1988 to 2010 with follow-up data through December 31, 2019. We fit weighted Cox proportional hazards models to estimate adjusted hazard ratios (aHRs) of cancer death between educational attainment/AL (adjusted for age, income, and smoking status).

RESULTS

AA women with less than a high school diploma living with high AL had nearly a 3-fold increased risk (unadjusted HR: 2.98; 95%C CI: 1.24-7.15) of cancer death compared to AA college graduates living with low AL. However, after adjusting for age, this effect attenuated (age-adjusted HR: 1.11; 95% CI: 0.45-2.74). AA women with high AL had 2.3-fold increased risk of cancer death (fully adjusted HR: 2.26; 95% CI: 1.10-4.57) when compared to AA with low AL, specifically among women with high school diploma or equivalent and without history of cancer.

CONCLUSIONS

Our findings suggest that high allostatic load is associated with a higher risk of cancer mortality among AA women with lower educational attainment, while no such association was observed among AA women with higher educational attainment. Thus, educational attainment plays a modifying role in the relationship between allostatic load and the risk of cancer death for AA women. Higher education can bring several benefits, including improved access to medical care and enhanced medical literacy, which in turn may help mitigate the adverse impact of AL and the heightened risk of cancer mortality among AA women.

Physical attractiveness and cardiometabolic risk

OBJECTIVES

There is only limited evidence suggesting that physical attractiveness and individuals' actual health are causally linked. Past studies demonstrate that characteristics related to physical attractiveness are more likely to be present in healthy individuals, including those with better cardiovascular and metabolic health, yet many of these studies do not account for individuals' initial health and socioeconomic characteristics, which are related to both physical attractiveness and later life health.

METHODS

We use panel survey data from the National Longitudinal Study of Adolescent to Adult Health in the United States to examine the relationship between interviewer-rated in-person physical attractiveness and actual cardiometabolic risk (CMR) based on a set of relevant biomarkers: LDL cholesterol, glucose mg/dL, C-reactive protein, systolic and diastolic blood pressure, and resting heart rate.

RESULTS

We identify a robust relationship between individuals' physical attractiveness and 10-year follow up actual health measured by the levels of CMR. Individuals of above-average attractiveness appear to be noticeably healthier than those who are described as having average attractiveness. We find that individuals' gender and race/ethnicity do not have a major effect on the described relationship. The link between physical attractiveness and health is affected by interviewers' main demographic characteristics. We carefully address the possibility of confounders affecting our results including sociodemographic and socioeconomic characteristics, cognitive and personality traits, initial health problems and BMI.

CONCLUSION

Our findings are largely in line with the evolutionary perspective which assumes that physical attractiveness is linked to individuals' biological health. Being perceived as physically attractive might also imply, among other aspects, high levels of satisfaction with life, self-confidence and ease of finding intimate partners, all of which can positively affect individuals' health.

A mixed-methods study of race-based stress and trauma affecting Asian Americans during COVID

COVID-19 propelled anti-Asian racism around the world; empirical research has yet to examine the phenomenology of racial trauma affecting Asian communities. Our mixed methods study of 215 Asian participants of 15 ethnicities examined experiences of racism during COVID and resulting psychological sequelae. Through qualitative content analysis, themes emerged of emotional, cognitive, and behavioral changes resulting from these racialized perpetrations, including: internalizing emotions of fear, sadness, and shame; negative alterations in cognitions such as reduced trust and self worth; and behavioral isolation, avoidance, and hypervigilance, in addition to positive coping actions of commitment to racial equity initiatives. We engaged in data triangulation with quantitative Mann-Whitney U tests, finding that those who experienced COVID discrimination had significantly higher racial trauma and PTSD scores compared to those who did not. Our convergent findings provide clinicians with novel ways to assess the ongoing impact of racial trauma and implement appropriate interventions for clients.

Allostatic load and incident heart failure in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study

BACKGROUND

Allostatic load (AL) is the physiologic "wear and tear" on the body from stress. Yet, despite stress being implicated in the development heart failure (HF), it is unknown whether AL is associated with incident HF events.

METHODS

We examined 16,765 participants without HF at baseline from the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. The main exposure was AL score quartile. AL was determined according to 11 physiologic parameters, whereby each parameter was assigned points (0-3) based on quartiles within the sample, and points were summed to create a total AL score ranging from 0-33. The outcome was incident HF event. We examined the association between AL quartile (Q1-Q4) and incident HF events using Cox proportional hazards models, adjusted for demographics, socioeconomic factors, and lifestyle.

RESULTS

The mean age was 64 ± 9.6 years, 61.5% were women, and 38.7% were Black participants. Over a median follow up of 11.4 years, we observed 750 incident HF events (635 HF hospitalizations and 115 HF deaths). Compared to the lowest AL quartile (Q1), the fully adjusted hazards of an incident HF event increased in a graded fashion: Q2 HR 1.49 95% CI 1.12-1.98; Q3 HR 2.47 95% CI 1.89-3.23; Q4 HR 4.28 95% CI 3.28-5.59. The HRs for incident HF event in the fully adjusted model that also adjusted for CAD were attenuated, but remained significant and increased in a similar, graded fashion by AL quartile. There was a significant age interaction (p-for-interaction < 0.001), whereby the associations were observed across each age stratum, but the HRs were highest among those aged < 65 years.

CONCLUSION

AL was associated with incident HF events, suggesting that AL could be an important risk factor and potential target for future interventions to prevent HF.

The COVID-19, racism, and violence syndemic: Evidence from a qualitative study with Black residents of Chicago

The COVID-19 pandemic emerged in the United States in the shadows of a vast history of structural racism and community and police violence that disproportionately affect Black communities. Collectively, they have created a syndemic, wherein COVID-19, racism, and violence are mutually reinforcing to produce adverse health outcomes. The purpose of this study was to understand the COVID-19, racism, and violence syndemic and examine how structural racism and violence contributed to the disproportionate impact of COVID-19 on Black communities. In early 2021, we conducted phenomenological qualitative interviews with 50 Black residents of Chicago. Interview transcripts were coded and analyzed using thematic analysis. We identified four primary themes in our analyses: 1) the intersection of racism and violence in Chicago; 2) longstanding inequities were laid bare by COVID-19; 3) the pervasiveness of racism and violence contributes to poor mental health; 4) and COVID-19, racism and violence emerged as a syndemic. Our findings underscore the importance of addressing social and structural factors in remediating the health and social consequences brought about by COVID-19.

Inequalities in Exposure to Firearm Violence by Race, Sex, and Birth Cohort From Childhood to Age 40 Years, 1995-2021

Importance

The past quarter-century has seen both sharp declines and increases in firearm violence in the United States. Yet, little is known about the age of first exposure to firearm violence and how it may differ by race, sex, and cohort.

Objective

To examine race, sex, and cohort differences in exposure to firearm violence in a representative longitudinal study of children who grew up in periods with varying rates of firearm violence in the United States and to examine spatial proximity to firearm violence in adulthood.

Design, Setting, and Participants

This population-based representative cohort study included multiple cohorts of children followed-up from 1995 through 2021 in the Project on Human Development in Chicago Neighborhoods (PHDCN). Participants included Black, Hispanic, and White respondents from 4 age cohorts of Chicago, Illinois, residents, with modal birth years of 1981, 1984, 1987, and 1996. Data analyses were conducted from May 2022 to March 2023.

Main Outcomes and Measures

Firearm violence exposure, including age when first shot, age when first saw someone shot, and past-year frequency of fatal and nonfatal shootings within 250 m of residence.

Results

There were 2418 participants in wave 1 (in the mid-1990s), and they were evenly split by sex, with 1209 males (50.00%) and 1209 females (50.00%). There were 890 Black respondents, 1146 Hispanic respondents, and 382 White respondents. Male respondents were much more likely than female respondents to have been shot (adjusted hazard ratio [aHR], 4.23; 95% CI, 2.28-7.84), but only moderately more likely to have seen someone shot (aHR, 1.48; 95% CI, 1.27-1.72). Compared with White individuals, Black individuals experienced higher rates of all 3 forms of exposure (been shot: aHR, 3.05; 95% CI, 1.22-7.60; seen someone shot: aHR, 4.69; 95% CI, 3.41-6.46; nearby shootings: adjusted incidence rate ratio [aIRR], 12.40; 95% CI, 6.88-22.35), and Hispanic respondents experienced higher rates of 2 forms of violence exposure (seen someone shot: aHR, 2.59; 95% CI, 1.85-3.62; nearby shootings: aIRR, 3.77; 95% CI, 2.08-6.84). Respondents born in the mid-1990s who grew up amidst large declines in homicide but reached adulthood during city and national spikes in firearm violence in 2016 were less likely to have seen someone shot than those born in the early 1980s who grew up during the peak of homicide in the early 1990s (aHR, 0.49; 95% CI, 0.35-0.69). However, the likelihood of having been shot did not significantly differ between these cohorts (aHR, 0.81; 95% CI, 0.40-1.63).

Conclusions and Relevance

In this longitudinal multicohort study of exposure to firearm violence, there were stark differences by race and sex, yet the extent of exposure to violence was not simply the product of these characteristics. These findings on cohort differences suggest changing societal conditions were key factors associated with whether and at what life stage individuals from all race and sex groups were exposed to firearm violence.

Association of Allostatic Load With All-Cause Mortality in Patients With Breast Cancer

Importance

Elevated allostatic load (AL) has been associated with adverse socioenvironmental stressors and tumor characteristics that convey poor prognosis in patients with breast cancer. Currently, the association between AL and all-cause mortality in patients with breast cancer is unknown.

Objective

To examine the association between AL and all-cause mortality in patients with breast cancer.

Design, Setting, and Participants

This cohort study used data from an institutional electronic medical record and cancer registry at the National Cancer Institute Comprehensive Cancer Center. Participants were patients with breast cancer diagnoses (stage I-III) between January 1, 2012, through December 31, 2020. Data were analyzed from April 2022 through November 2022.

Exposure

AL was expressed as a summary score calculated by assigning 1 point for biomarkers in the worst sample quartile. High AL was defined as AL greater than the median.

Main Outcomes and Measures

The main outcome was all-cause mortality. A Cox proportional hazard models with robust variance tested the association between AL and all-cause mortality.

Results

There were 4459 patients (median [IQR] age, 59 [49-67] years) with an ethnoracial distribution of 3 Hispanic Black patients (0.1%), 381 non-Hispanic Black patients (8.5%), 23 Hispanic White patients (0.5%), 3861 non-Hispanic White patients (86.6%), 27 Hispanic patients with other race (0.6%), and 164 non-Hispanic patients with other race (3.7%). The mean (SD) AL was 2.6 (1.7). Black patients (adjusted relative ratio [aRR], those with 1.11; 95% CI, 1.04-1.18), single marital status (aRR, 1.06; 95% CI, 1.00-1.12), and those with government-supplied insured (Medicaid aRR, 1.14; 95% CI, 1.07-1.21; Medicare aRR, 1.11; 95% CI, 1.03-1.19) had a higher adjusted mean AL than those who were White, married/living as married, or privately insured, respectively. Adjusting for sociodemographic, clinical, and treatment factors, high AL was associated with a 46% increase in mortality risk (hazard ratio [HR], 1.46; 95% CI, 1.11-1.93) over low AL. Similarly, compared with patients in the first AL quartile, those in the third quartile (HR, 1.53; 95% CI, 1.07-2.18) and the fourth quartile (HR, 1.79; 95% CI, 1.16-2.75) had significantly increased risks of mortality. There was a significant dose-dependent association between increased AL and a higher risk of all-cause mortality. Furthermore, AL remained significantly associated with higher all-cause mortality after adjusting for the Charlson Comorbidity Index.

Conclusions and Relevance

These findings suggest increased AL is reflective of socioeconomic marginalization and associated with all-cause mortality in patients with breast cancer.

Effect of Neighborhood Deprivation Index on Breast Cancer Survival in the United States

Purpose To analyze the association between the Neighborhood Deprivation Index (NDI) and clinical outcomes of early-stage breast cancer (BC). Methods Surveillance, Epidemiology and End Results (SEER) database is queried to evaluate overall survival (OS) and disease-specific survival (DSS) of early- stage BC patients diagnosed between 2010-2016. Cox multivariate regression was performed to measure the association between NDI (Quintiles corresponding to most deprivation (Q1), above average deprivation (Q2), average deprivation (Q3), below average deprivation (Q4), least deprivation (Q5)) and OS/DSS. Results Of the 88,572 early-stage BC patients, 27.4% (n = 24,307) were in the Q1 quintile, 26.5% (n = 23,447) were in the Q3 quintile, 17% (n = 15,035) were in the Q2 quintile, 13.5% (n = 11,945) were in the Q4 quintile, and 15.6% (n = 13,838) were in the Q5 quintile. There was a predominance of racial minorities in the Q1 and Q2 quintiles with Black women being 13-15% and Hispanic women being 15% compared to only 8% Black women and 6% Hispanic women in the Q5 quintile (p < 0.001). In multivariate analysis, in the overall cohort, those who live in Q2 and Q1 quintile have inferior OS and DSS compared to those who live in Q5 quintile (OS:- Q2: Hazard Ratio (HR) 1.28, Q1: HR 1.2; DSS:- Q2: HR 1.33, Q1: HR 1.25, all p < 0.001). Conclusion Early-stage BC patients from areas with worse NDI have poor OS and DSS. Investments to improve the socioeconomic status of areas with high deprivation may help to reduce healthcare disparities and improve breast cancer outcomes.

Investigating the Association between Educational Attainment and Allostatic Load with Risk of Cancer Mortality among African American Women

Background African American (AA) women navigate the world with multiple intersecting marginalized identities. Accordingly, AA women have higher cumulative stress burden or allostatic load (AL) compared to other women. AL correlates with poorer health outcomes and increased risk of cancer death. However, research indicates AA women with a college degree or higher have lower AL than AA women with less than a high school diploma. We examined whether educational attainment differences and AL status in AA women are associated with long-term risk of cancer mortality. Methods We performed a retrospective analysis among 4,677 AA women respondents using National Health and Nutrition Examination Survey (NHANES) data from 1988 through 2010 with follow up data through December 31, 2019. We fit Cox proportional hazards models to estimate adjusted hazard ratios (aHRs) of cancer death between educational attainment/AL (adjusted for age, sociodemographic, and health factors). Results AA women with less than a high school diploma living with high AL had nearly a 3-fold increased risk (unadjusted HR: 2.98; 95%C CI: 1.24â€"7.15) of cancer death compared to AA college graduates living with low AL. However, after adjusting for age, the increased risk of cancer death in those with less than a high school diploma and high AL attenuated (age-adjusted HR: 1.11; 95% CI: .45-2.74). Conclusions Differences in educational attainment and AL in AA women were not associated with increased risk of cancer mortality when adjusted for age. Previous studies have shown that increased allostatic load is associated with increased risk of cancer death. However, for African American women, higher educational attainment does not modify the risk of cancer mortality. The benefits that may come along with higher education such as increased access to medical care and better medical literacy do not change the risk of cancer mortality in AA women.

Allostatic load and cardiovascular outcomes in males with prostate cancer

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death in men with prostate cancer (PC). Accumulated stress plays an important role in CVD development. The cumulative burden of chronic stress and life events can be measured using allostatic load (AL).

METHODS

The initial cohort included males aged 18 years and older diagnosed with PC (2005-2019). AL was modeled as an ordinal variable (0-11). Fine-Gray competing risk regressions measured the impact of precancer diagnosis AL and postdiagnosis AL in 2-year major cardiac events (MACE). The effect of AL changes over time on MACE development was calculated via piecewise Cox regression (before, and 2 months, 6 months, and 1 year after PC diagnosis).

RESULTS

We included 5261 PC patients of which 6.6% had a 2-year MACE. For every 1-point increase in AL before and within 60 days after PC diagnosis, the risk of MACE increased 25% (adjusted hazard ratio [aHR] =1.25, 95% confidence interval [CI] = 1.18 to 1.33) and 27% (aHR = 1.27, 95% CI = 1.20 to 1.35), respectively. Using AL as a time-varying exposure, the risk of MACE increased 19% (aHR = 1.19, 95% CI = 1.11 to 1.27), 22% (aHR = 1.22, 95% CI = 1.14 to 1.33), 28% (aHR = 1.28, 95% CI = 1.23 to 1.33), and 31% (aHR = 1.31, 95% CI = 1.27 to 1.35) for every 1-point increase in AL before, 2 months after, 6 months after, and 1 year after PC diagnosis, respectively.

CONCLUSION

AL and its changes over time are associated with MACE in PC patients, suggesting a role of a biological measure of stress as a marker of CVD risk among men with PC.

Racial disparities among older adults with acute myocardial infarction: The SILVER-AMI study

BACKGROUND

Despite an aging population, little is known about racial disparities in aging-specific functional impairments and mortality among older adults hospitalized for acute myocardial infarction (AMI).

METHODS

We analyzed data from patients aged 75 years or older who were hospitalized for AMI at 94 US hospitals from 2013 to 2016. Functional impairments and geriatric conditions were assessed in-person during the AMI hospitalization. The association between race and risk of mortality (primary outcome) was evaluated with logistic regression adjusted sequentially for age, clinical characteristics, and measures of functional impairment and other conditions associated with aging.

RESULTS

Among 2918 participants, 2668 (91.4%) self-identified as White and 250 (8.6%) as Black. Black participants were younger (80.8 vs 81.7 years; p = 0.010) and more likely to be female (64.8% vs 42.5%; p < 0.001). Black participants were more likely to present with impairments in cognition (37.6% vs 14.5%; p < 0.001), mobility (66.0% vs 54.6%; p < 0.001) and vision (50.1% vs 35.7%; p < 0.001). Black participants were also more likely to report a disability in one or more activities of daily living (22.4% vs 13.0%; p < 0.001) and an unintentional loss of more than 10 lbs in the year prior to hospitalization (37.2% vs 13.0%; p < 0.001). The unadjusted odds of 6-month mortality among Black participants (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.4-2.8) attenuated to non-significance after adjustment for age, clinical characteristics (OR 1.70, 95% CI 1.7, 1.2-2.5), and functional/geriatric conditions (OR 1.5, 95% CI 1.0-2.2).

CONCLUSIONS

Black participants had a more geriatric phenotype despite a younger average age, with more functional impairments. Controlling for functional impairments and geriatric conditions attenuated disparities in 6-month mortality somewhat. These findings highlight the importance of systematically assessing functional impairment during hospitalization and also ensuring equitable access to community programs to support post-AMI recovery among Black older adults.

Longitudinal associations between allostatic load, pet ownership, and socioeconomic position among U.S. adults aged 50

It is hypothesized that pets provide benefits to human health by buffering the deleterious effects of stress, but varying exposure to chronic stress via social position is rarely considered in these conceptual and empirical models. Allostatic load is an index of biological and physical measures that represents cumulative wear and tear on the body via chronic stress exposure. In this study, we use the 2006-2016 waves of the Health and Retirement Study, a nationally representative, longitudinal panel survey of adults aged 50+ in the United States, to test whether and to what extent pet ownership has an impact on allostatic load, and whether pet ownership moderates the effects of socioeconomic position on allostatic load. Linear mixed effects regression models revealed that pet owners had significantly lower allostatic load scores than those who do not own pets; however, after adjusting for socioeconomic position (i.e., wealth, education, race, ethnicity, gender, marital status), the effect of pet ownership was no longer significant. We estimated a series of models stratified by sociodemographic groups to test moderation effects. Among those who had a high school education, pet owners had lower allostatic load scores, whereas among those who had attended some college, pet owners had higher scores. Among those who were aged 80+, pet owners had higher scores than those who did not own pets. These findings suggest that the magnitude of the effect of pet ownership on allostatic load may not be sufficient to counteract experiences of high chronic stress as experienced by lower-status groups. Supporting the human-animal bond may contribute to improving older adult population health if paired with efforts to address the underlying causes of population health disparities.

Disparities in health condition diagnoses among aging transgender and cisgender medicare beneficiaries, 2008-2017

INTRODUCTION

The objective of this research is to provide national estimates of the prevalence of health condition diagnoses among age-entitled transgender and cisgender Medicare beneficiaries. Quantification of the health burden across sex assigned at birth and gender can inform prevention, research, and allocation of funding for modifiable risk factors.

METHODS

Using 2009-2017 Medicare fee-for-service data, we implemented an algorithm that leverages diagnosis, procedure, and pharmacy claims to identify age-entitled transgender Medicare beneficiaries and stratify the sample by inferred gender: trans feminine and nonbinary (TFN), trans masculine and nonbinary (TMN), and unclassified. We selected a 5% random sample of cisgender individuals for comparison. We descriptively analyzed (means and frequencies) demographic characteristics (age, race/ethnicity, US census region, months of enrollment) and used chi-square and t-tests to determine between- (transgender vs. cisgender) and within-group gender differences (e.g., TMN, TFN, unclassified) difference in demographics (p<0.05). We then used logistic regression to estimate and examine within- and between-group gender differences in the predicted probability of 25 health conditions, controlling for age, race/ethnicity, enrollment length, and census region.

RESULTS

The analytic sample included 9,975 transgender (TFN n=4,198; TMN n=2,762; unclassified n=3,015) and 2,961,636 cisgender (male n=1,294,690, female n=1,666,946) beneficiaries. The majority of the transgender and cisgender samples were between the ages of 65 and 69 and White, non-Hispanic. The largest proportion of transgender and cisgender beneficiaries were from the South. On average, transgender individuals had more months of enrollment than cisgender individuals. In adjusted models, aging TFN or TMN Medicare beneficiaries had the highest probability of each of the 25 health diagnoses studied relative to cisgender males or females. TFN beneficiaries had the highest burden of health diagnoses relative to all other groups.

DISCUSSION

These findings document disparities in key health condition diagnoses among transgender Medicare beneficiaries relative to cisgender individuals. Future application of these methods will enable the study of rare and anatomy-specific conditions among hard-to-reach aging transgender populations and inform interventions and policies to address documented disparities.

Allostatic Load Measurement: A Systematic Review of Reviews, Database Inventory, and Considerations for Neighborhood Research

BACKGROUND

Neighborhoods are critical to understanding how environments influence health outcomes. Prolonged environmental stressors, such as a lack of green spaces and neighborhood socioeconomic disadvantage, have been associated with higher allostatic load levels. Since allostatic load levels experienced earlier in life have stronger associations with mortality risk, neighborhoods may be uniquely suited to monitor and mitigate the impacts of environmental stressors. Researchers often study allostatic load in neighborhoods by utilizing administrative boundaries within publicly accessible databases as proxies for neighborhoods.

METHODS

This systematic review of reviews aims to identify commonly used biomarkers in the measurement of allostatic load, compare measurement approaches, inventory databases to study allostatic load, and spotlight considerations referenced in the literature where allostatic load is studied in neighborhoods. The review was conducted using the search term "allostatic load" in the MEDLINE, CINAHL, and PsychINFO databases. The search results were filtered to include reviews.

RESULTS

The search returned 499 articles after deduplication. Overall, 18 synthesis reviews met the inclusion criteria and were retained for extraction. The synthesis reviews analyzed represented 238 studies published from 1995 to 2020. The original ten biomarkers were most often used to measure allostatic load. More recently, body mass index and C-reactive protein have additionally been frequently used to measure allostatic load burden.

CONCLUSIONS

The scientific contributions of this study are that we have identified a clear gap in geographic considerations when studying allostatic load. The implication of this study is that we have highlighted geographic concepts when conducting neighborhood-level research using administrative databases as a neighborhood proxy and outlined emerging future trends that can enable future study of allostatic load in the neighborhood context.

Responding to "Don't Say Gay" Laws in the US: Research Priorities and Considerations for Health Equity

INTRODUCTION

Despite increased legal rights for lesbian, gay, bisexual, transgender, and queer-identifying (LGBTQ +) people in the USA over the past 30 years, there has been an increasing number of anti-LGBTQ + laws proposed and passed at the state level. One of the most notorious laws, Florida's HB 1557, also known as the "Don't Say Gay" law, garnered substantial national attention for prohibiting discussions of sexual orientation or gender identity in public school classrooms. Other states quickly proposed similar laws, but little scholarship exists on the potential impacts of these laws.

METHODS

We explore the potential health equity ramifications of laws like Florida's HB 1557, focusing on the individual, interpersonal, and broader policy and practice implications. Examining these policies through the lens of political determinants of health, we identify theoretical and methodological approaches needed to address recent "Don't Say Gay" policies.

RESULTS

Theoretical approaches emphasizing power, intersectionality, and the role of politics in health should guide research examining the impacts of recent anti-LGBTQ + policies. Laws like Florida's HB 1557 emphasize the need for methodological approaches that emphasize collaborative engagement between researchers and community members, and future research may be needed to understand how stressors created by law and policy can have individual and interpersonal consequences.

CONCLUSIONS

Public health researchers have a role to play in reversing policies that negatively affect LGBTQ + individuals and undermine health equity. Research combating harmful policies may require theoretical approaches attentive to power differences and methodological approaches that squarely focus on disrupting power imbalances.

Anticipation of Racially Motivated Police Brutality and Youth Mental Health

Purpose

Exposure to police brutality is a significant risk to adolescent mental health. This study extends this literature by exploring connections between anticipation of racially motivated police brutality and multiple facets of adolescent mental health.

Methods

Students ages 14 to 18 (n = 151) were recruited from a study administered in Baltimore City public schools. Between December 2020 and July 2021, participants completed a questionnaire assessing anticipatory stress regarding racially motivated police brutality and current mental health. Regression models examined associations between this anticipatory stress and mental health. Latent profile and regression analyses were used to examine whether anticipatory stress was more salient among adolescents with comorbid mental health symptoms, compared to those without comorbid symptoms.

Results

Youth with anticipatory stress stemming from both personal and vicarious police brutality had more symptoms of anxiety, depression, and PTSD, as well as lower hope, compared to youth without anticipatory stress. The association between anticipatory stress and anxiety was stronger for girls than boys.

Conclusions

Findings from this study highlight racialized police brutality as a common anticipated stressor among youth, particularly for girls. Findings have implications for policing interventions, including development of additional trainings for police officers and promoting positive police/youth interactions.

A Framework for Interfacing and Partnering with Environmental Justice Communities as a Prelude to Human Health and Hazard Identification in the Vulnerable Census Tracts of Columbus, Ohio

Columbus, Ohio is one of the more prosperous, well-educated, and progressive cities in the United States. However, it ranks as the second worst life expectancy at birth, has a census tract wealth gap (27-year disparity), and one of the higher infant mortality rates in the country. These data suggest that there are likely several high-risk, vulnerable neighborhoods in Columbus with residents experiencing disparate and adverse outcomes. Illustrative of this fact are studies that have examined the social processes and mechanisms through which neighborhood contexts are at the forefront, including exposures to chemical stressors such as particulate matter (PM_2.5) as well as non-chemical stressors including violence, social determinants of health, zoning, and land use policies. It is documented that disparate and adverse outcomes are magnified in the vulnerable neighborhoods on the Near East Side as compared to Columbus city proper, Franklin County and/or the state of Ohio. As such, we developed a nuanced community engagement framework to identify potential environmental hazards associated with adverse pregnancy outcomes in those census tracts. The refined framework uses a blended version of traditional community-based participatory research (CBPR) models and is referred to as E⁶, Enhancing Environmental Endeavors via e-Equity, Education, and Empowerment.

A consequence of mass incarceration: county-level association between jail incarceration rates and poor mental health days

INTRODUCTION

Mass incarceration has mental health consequences on those directly affected; some studies have also shown spillover effects on the physical health of the surrounding population. There is a dearth of research on the spillover mental health consequences of mass incarceration. This study aimed to quantify a consequence of mass incarceration which may adversely affect the population's health and widen health disparities.

METHODS

Using data from the Vera Institute's Incarceration Trends 2.2 and the Robert Wood Johnson County Health Rankings, the association between county-level (n = 2823) counts of jail incarceration and reported number of poor mental health days within the past 30 days in the United States in 2018 was examined. To conduct the analysis, a negative binomial regression model was fit, adjusting for State and key demographic covariates.

RESULTS

A change in jail incarceration rate from the first to the second and third tertiles was associated with 10.14% and 14.52% increases, respectively. For every 1% increase in the rate of mass incarceration, there was a statistically significant 15% increase in the average number of reported poor mental health days over the past 30 days.

DISCUSSION

Mass incarceration is a threat to mental health as well as the well-being of the surrounding population. This can be attributed to the spillover effects that extend beyond those who are directly affected by mass incarceration. Interventions to reduce jail incarceration as well as address the mental health needs of those living in high-incarceration rate areas should be prioritized in order to reduce health inequities and augment health outcomes for all residents of the United States.

Risk of Presenting with Poor-Prognosis Metastatic Cancer in Adolescents and Young Adults: A Population-Based Study

Having metastatic disease at diagnosis poses the great risk of death among AYAs with cancer from all sociodemographic subgroups. This “landscape” study utilized United States Surveillance, Epidemiology, and End Results Program data from 2000−2016 to identify subgroups of AYAs at highest risk for presenting with metastases across twelve cancer sites having a poor-prognosis (5-year survival <50% with metastases). Adjusted odds ratios for risk of metastatic disease presentation were compared for AYAs in aggregate and by sociodemographic subgroup (race/ethnicity, sex, socioeconomic status [SES]). In general, AYAs who were male, racial/ethnic minorities, or low SES were at consistently greatest risk of metastases. Strikingly, having metastatic melanoma was independently associated with multiple AYA sociodemographic subgroups, including males (aOR 3.11 [95% CI 2.64−3.66]), non-Hispanic Blacks (4.04 [2.32−7.04]), Asian Pacific Islanders (2.99 [1.75−5.12]), Hispanics (2.37 [1.85−3.04]), and low SES (2.30 [1.89−2.80]). Non-Hispanic Blacks were more likely to present with metastatic cancer in all sites, except for bone, rhabdomyosarcoma, and stomach. Low SES AYAs are more likely to present with metastatic melanoma, bone tumors, soft tissue sarcomas, breast, cervical, lung, and stomach carcinomas. Building on these results, future cancer-specific studies should investigate the connection between sociodemographic risk factors and biological drivers of metastases. This line of research has potential to inform targeted public health and screening efforts to facilitate risk reduction and earlier detection of these deadly diseases.

Association of Race and Area Deprivation With Breast Cancer Survival Among Black and White Women in the State of Georgia

Importance

Increasing evidence suggests that low socioeconomic status and geographic residence in disadvantaged neighborhoods contribute to disparities in breast cancer outcomes. However, little epidemiological research has sought to better understand these disparities within the context of location.

Objective

To examine the association between neighborhood deprivation and racial disparities in mortality among Black and White patients with breast cancer in the state of Georgia.

Design, Setting, and Participants

This population-based cohort study collected demographic and geographic data from patients diagnosed with breast cancer between January 1, 2004, and February 11, 2020, in 3 large health care systems in Georgia. A total of 19 580 patients with breast cancer were included: 12 976 from Piedmont Healthcare, 2285 from Grady Health System, and 4319 from Emory Healthcare. Data were analyzed from October 2, 2020, to August 11, 2022.

Exposures

Area deprivation index (ADI) scores were assigned to each patient based on their residential census block group. The ADI was categorized into quartile groups, and associations between ADI and race and ADI × race interaction were examined.

Main Outcomes and Measures

Cox proportional hazards regression models were used to compute hazard ratios (HRs) and 95% CIs associating ADI with overall mortality by race. Kaplan-Meier curves were used to visualize mortality stratified across racial and ADI groups.

Results

Of the 19 580 patients included in the analysis (mean [SD] age at diagnosis, 58.8 [13.2] years), 3777 (19.3%) died during the course of the study. Area deprivation index contributed differently to breast cancer outcomes for Black and White women. In multivariable-adjusted models, living in a neighborhood with a greater ADI (more deprivation) was associated with increased mortality for White patients with breast cancer; compared with the ADI quartile of less than 25 (least deprived), increased mortality HRs were found in quartiles of 25 to 49 (1.22 [95% CI, 1.07-1.39]), 50 to 74 (1.32 [95% CI, 1.13-1.53]), and 75 or greater (1.33 [95% CI, 1.07-1.65]). However, an increase in the ADI quartile group was not associated with changes in mortality for Black patients with breast cancer (quartile 25 to 49: HR, 0.81 [95% CI, 0.61-1.07]; quartile 50 to 74: HR, 0.91 [95% CI, 0.70-1.18]; and quartile ≥75: HR, 1.05 [95% CI, 0.70-1.36]). In neighborhoods with an ADI of 75 or greater, no racial disparity was observed in mortality (HR, 1.11 [95% CI, 0.92-1.36]).

Conclusions and Relevance

Black women with breast cancer had higher mortality than White women in Georgia, but this disparity was not explained by ADI: among Black patients, low ADI was not associated with lower mortality. This lack of association warrants further investigation to inform community-level approaches that may mitigate the existing disparities in breast cancer outcomes in Georgia.

A multi-center study on the association between serum magnesium levels and allostatic load in hemodialysis patients

Objective: Serum magnesium (Mg²⁺) levels are associated with insulin resistance, hypertension, lipid abnormalities, and inflammation. However, limited studies have indicated the relationship between Mg²⁺ and multiple system indexes. The purpose of this study was to investigate the association between Mg²⁺ and allostatic load (AL) in hemodialysis patients.

Methods: A cross-sectional survey was conducted on hemodialysis patients from different centers in Anhui Province, China, between January and December 2020. A total of 3,025 hemodialysis patients were recruited. Their clinical data were measured before hemodialysis. Information was collected by an online self-reported questionnaire and medical record. Serum Mg²⁺ was divided into three groups by tertiles. A score of AL greater than or equal to 3 was defined as high AL. A binary logistic regression model was applied to examine the relationship between serum Mg²⁺ and AL.

Results: A total of 1,222 patients undergoing hemodialysis were included, 60% of whom were males (733/1,222). The mean (standard deviation) age of patients was 55.90 (12.75). The median level of serum Mg²⁺ was 1.22 mmol/L. The rate of high AL levels was 23.4%. Serum Mg²⁺ was negatively correlated with body mass index, fasting blood glucose (Glu), and C-reactive protein and positively correlated with high-density lipoprotein, low-density lipoprotein, total cholesterol, diastolic blood pressure (DBP), and serum phosphorus. After adjusting for gender, anxiety, diabetes, family residence, lipid-lowering agents, antihypertensive medications, albumin, and Glu, the binary logistic regression model showed that patients with lower levels of serum Mg²⁺ were more likely have high AL (OR for the T1 group of serum Mg²⁺:1.945, 95% CI: 1.365–2.773, and OR for the T2 group of serum Mg²⁺:1.556, 95% CI: 1.099–2.201).

Conclusion: Our data support the hypothesis that higher serum Mg²⁺ concentrations may contribute to lower health risk in hemodialysis populations. Further randomized controlled trials and cohort studies are warranted to verify whether Mg²⁺ supplementation could be part of routine examinations in hemodialysis populations.

Allostatic load predicts racial disparities in intracerebral hemorrhage cognitive outcomes

A large portion of stroke disparities remains unexplained, even after adjusting for demographic, comorbidity, and health care access variables. There is a critical need to close this knowledge gap by investigating novel factors that may contribute to stroke disparities. Allostatic load (AL) is the lifetime adverse physiologic impact of needing to adjust to socially structured stressors such as racism. AL has been shown to increase health vulnerability and worsen outcomes in marginalized populations. We sought to assess the differential impact of AL on cognitive outcomes post intracerebral hemorrhage (ICH) across race-ethnicity. The Intracerebral Hemorrhage Outcomes Project (ICHOP) prospectively collected data from patients presenting to Columbia Medical Center with ICH from 3/2009 to 5/2016. Data included demographics, stroke scores, labs, complications, neuroimaging, medical history, and discharge data. Five markers of AL (HbA1c, WBC, SBP, HR, ALB) were obtained. An AL score was generated by summing the elements in each patient that fell outside normal ranges, with AL score ranging 0–5. A linear regression model, adjusted for stroke severity and ICH volumes, was used to evaluate the relationship between AL and Modified Telephone Interview for Cognitive Status (TICS-m) at discharge, stratified by race-ethnicity. Among 248 white, 195 black, and 261 Hispanic ICH patients, neither mean AL nor mean TICS differed by race/ethnicity (p = 0.51, p = 0.79 respectively). In the overall cohort AL did not predict TICS at discharge (Beta -1.0, SE 1.1, p = 0.353). In Whites (beta 1.18, SE 2.5, p = 0.646) and Hispanics (beta -0.95, SE 1.6, p = 0.552) AL was not associated with TICS at discharge. In Black patients, higher AL was associated with a decrease in TICS at discharge (beta -3.2, SE 1.5, p = 0.049). AL is an important determinant of post ICH outcomes for certain minority populations. AL may explain some of the unexplained health disparities in stroke populations.

Religious service attendance and mortality among older Black men

Religious institutions have been responsive to the needs of Black men and other marginalized populations. Religious service attendance is a common practice that has been associated with stress management and extended longevity. The objective of this study was to examine the relationship between religious service attendance and all-cause mortality among Black men 50 years of age and older. Data for this study were from NHANES III (1988–1994). The analytic sample (n = 839) was restricted to participants at least 50 years of age at the time of interview who self-identified as Black and male. Mortality was the primary outcome for this study and the NHANES III Linked Mortality File was used to estimate race-specific, non-injury-related death rates using a probabilistic matching algorithm, linked to the National Death Index through December 31, 2015, providing up to 27 years follow-up. The primary independent variable was religious service attendance, a categorical variable indicating that participants attended religious services at least weekly, three or fewer times per month, or not at all. The mean age of participants was 63.6±0.3 years and 36.4% of sample members reported that they attended religious services one or more times per week, exceeding those attending three or fewer times per month (31.7%), or not at all (31.9%). Cox proportional hazard logistic regression models were estimated to determine the association between religious service attendance and mortality. Participants with the most frequent religious service attendance had a 47% reduction of all-cause mortality risk compared their peer who did not attend religious services at all (HR 0.53, CI 0.35–0.79) in the fully adjusted model including socioeconomic status, non-cardiovascular medical conditions, health behaviors, social support and allostatic load. Our findings underscore the potential salience of religiosity and spirituality for health in Black men, an understudied group where elevated risk factors are often present.

Education in the Jim Crow South and Black-White inequities in allostatic load among older adults

In the U.S., Black adults consistently have higher allostatic load – an indicator of physiological dysregulation – than White adults. Education is considered a likely mechanism given racial differences in attainment, but evidence is mixed. This may be due, in part, to data limitations that have made it difficult for scholars to account for the structurally rooted systemic racism that shaped the U.S. education system and led to large racial inequities in school term length and school attendance among older adults who grew up in the Jim Crow South. Our study addresses this limitation by linking historical data on Black and White segregated school systems in the U.S. South from 1919 to 1954 to the Health and Retirement Study (HRS) to determine if a new measure of educational attainment that accounts for structural racism that led to differences in the number of school days attended by Black and White students across years and states better explains Black-White inequities in allostatic load among older adults who attended school during Jim Crow. We restrict our sample to HRS respondents racialized as White or Black, who resided in the South when they were school-aged, completed primary/secondary school between 1919 and 1954, and provided a measure of allostatic load (n = 1932). We find that our new measure of schooling – duration in school – reduced the Black-White inequity in allostatic load more so than self-reported years of schooling whether we measured allostatic load continuously (34% vs 16%) or categorically (45% vs 20%). Our findings highlight the importance of identifying and using historically informed measures of schooling that account for structurally rooted systemic racism when trying to understand how education shapes the health of individuals racialized as Black in the United States.

•

U.S. Black adults show greater physiological dysregulation than White adults.

•

Mixed evidence as to whether education explains this inequity.

•

May be due to unmeasured structurally rooted systematic racism in early schooling.

•

Our education measure accounts for race inequity in term length and days attended.

•

This measure explains Black-White inequity in allostatic load.

Methodological approaches for studying structural racism and its biopsychosocial impact on health

BACKGROUND

Structural racism is a powerful determinant of health that drives health disparities, morbidity, and mortality across racialized and minoritized groups.

PURPOSE

This article discusses approaches for measuring structural racism and its resultant network of negative biopsychosocial consequences for health and well-being.

METHODS

We draw on prevailing theoretical models and approaches to characterize both the nature of structural racism and integrated methods for assessing its consequences across mental and physical health.

DISCUSSION

This article will serve to guide researchers in health-related disciplines to accurately assess the biopsychosocial consequences of structural racism in key populations.

Medical students' knowledge of race-related history reveals areas for improvement in achieving health equity

BACKGROUND

Medical schools have increasingly integrated social justice, anti-racism, and health equity training into their curricula. Yet, no research examines whether medical students understand the complex history of racial injustice. We sought to investigate the relationship between medical students' historical knowledge and their perceptions regarding health equity.

METHODS

Medical students at one large urban medical school self-rated their familiarity and importance of various racially-significant historical events and persons, as well as their agreement with statements regarding health equity, education, and preparedness to act. Descriptive and multivariate analyses were conducted in R.

RESULTS

Of 166 (RR=31.3%) participants, 96% agreed that understanding historical context is necessary in medicine; yet 65% of students could not describe the historical significance of racial events or persons. Only 57% felt that they understood this context, and the same percentage felt other medical students did not. A minority of students felt empowered (40%) or prepared (31%) to take action when they witness racial injustice in healthcare. Multiracial identity was significantly associated with increased knowledge of African American history (p<0.01), and a humanities background was significantly associated with increased knowledge of Latin American history (p=0.017). There was a positive, significant relationship between advocacy statements, such as "I have taken action" (p<0.001) and "I know the roots of racism" (p<0.001) with mean familiarity of historical events.

CONCLUSIONS

This study demonstrates that while students agree that racism has no place in healthcare, there remains a paucity of knowledge regarding many events and figures in the history of American race relations and civil rights, with implications for future physicians' patient care and health equity efforts.

Exploring racial disparities on the association between allostatic load and cancer mortality: A retrospective cohort analysis of NHANES, 1988 through 2019

Background

Methods

Results

Conclusions

Impact

•

Allostatic load (AL) is a biologic measure for the ‘wear and tear’ of chronic stress.

•

Studies suggests that racial minorities have higher allostatic load.

•

There is limited knowledge on the association between allostatic and cancer, by race.

•

We observed that AL may increase the risk of cancer death by 14%.

•

Among those aged <40 years, high AL increased cancer death risk by more than 80%.

Allostatic load in the context of disasters

Environmental disasters, pandemics, and other major traumatic events such as the Covid-19 pandemic or war contribute to psychosocial stress which manifests in a wide range of mental and physical consequences. The increasing frequency and severity of such events suggest that the adverse effects of toxic stress are likely to become more widespread and pervasive in the future. The allostatic load (AL) model has important elements that lend themselves well for identifying adverse health effects of disasters. Here we examine several articulations of AL from the standpoint of using AL to gauge short- and long-term health effects of disasters and to provide predictive capacity that would enable mitigation or prevention of some disaster-related health consequences. We developed a transdisciplinary framework combining indices of psychosocial AL and physiological AL to produce a robust estimate of overall AL in people affected by disasters and other traumatic events. In conclusion, we urge researchers to consider the potential of using AL as a component in a proposed disaster-oriented human health observing system.

Dimensions of acculturation and biological dysregulation among Latina/os: the role of ethnic background, gender, and immigrant generation

Objective: Research examining how different dimensions of acculturative beliefs and behaviors influence the risk of biological dysregulation among Latina/os is limited. This study examined associations between three types of acculturation and allostatic load (i.e. a multisystem index of biological dysregulation) across gender and Latina/o ethnic groups. Multiplicative models were also included in order to determine whether immigrant generation moderates acculturation-allostatic load relationships.Design: Data were drawn from the Hispanic Community Health Study/ Study of Latina/os. The sample consisted of 11,841 Latina/os from five ethnic groups: Cuban, Puerto Rican, Dominican, Mexican, and South/Central American. The measure for allostatic load was derived from 15 biomarker and anthropometric measures that were designed to capture cardiometabolic risk, glucose metabolism, cardiopulmonary function, inflammation, and organ function. Acculturation measures, immigrant generation, gender, ethnic background, and other covariates were derived from self-reports. Survey corrected ordinary least squares regressions were used to assess relationships between different dimensions of acculturation and allostatic load.Results: Results demonstrate dimensions of acculturation play a significant role in the risk of biological dysregulation for Latina/os with divergent results across gender and ethnic background. Estimates from the multiplicative models show immigrant generation moderates acculturation-allostatic load relationships, and relationships are dependent on gender and ethnic background.Conclusion: The study contributes to the understanding of how different dimensions of acculturation, as well as other important structural determinants of health, influence the risk of biological dysregulation among Latina/os. Finding from this study can inform targeted strategies designed to reduce the physiological consequences of chronic stress among Latina/os.

Investigating Racial Differences in Allostatic Load by Educational Attainment among Non-Hispanic Black and White Men

Education continues to be a key factor contributing to increased access to critical life-improving opportunities and has been found to be protective against Allostatic Load (AL). The purpose of this study was to assess AL among Non-Hispanic (NH) White and NH Black men with the same level of education. We used 1999–2016 National Health and Nutrition Examination Surveys (NHANES) data with an analytical sample of 6472 men (1842 NH Black and 4630 NH White), and nine biomarkers to measure AL, controlling for various demographic and health-related factors. NH Black men had a higher AL score than NH White men (39.1%, 842 vs. 37.7%, 1,975). Racial disparities in AL between NH Black and NH White men who have a college degree or above (PR: 1.49, CI: [1.24–1.80]) were observed. Models posited similar AL differences at every other level of education, although these were not statistically significant. The findings reveal that socioeconomic returns to education and the societal protective mechanisms associated with education vary greatly between White and Black men.

Racial differences in running and landing measures associated with injury risk vary by sex

It is unknown whether running and landing mechanics differ between racial groups despite injury disparities between African Americans (AA) and white Americans (WA). This study aimed to identify potential racial differences in running and landing mechanics and understand whether anthropometric, strength, and health status factors contribute to these differences. Venous blood samples, anthropometry, lower-extremity strength, and health status assessments were collected (n = 84, 18-30y). Three-dimensional motion capture and force plate data were recorded during 7 running and 7 drop vertical jump trials. Racial effects were determined, and regression models evaluated explanatory factors. AA females ran with longer stance times (p = 0.003) than WA females, while AA males ran with smaller loading rates (p = 0.046) and larger peak vertical ground reaction forces (p = 0.036) than WA males. Frontal plane knee range of motion during landing was greater in AA females (p = 0.033) than WA females; larger waist circumference and weaker knee extension strength accounted for this significance. Although outcome measures were associated with physiologic, anthropometric, and activity measures, their explanatory power for race was ambiguous, except for knee range of motion in females. Modifiable factors explaining racial effects during landing in females are potential intervention targets to reduce racial health disparities in running and landing injuries.

Investigation of Differences in Allostatic Load among Black Men by Level of Educational Attainment: High School Graduates Experience the Highest Levels of Stress

Allostatic load (AL)—the biological assessment of long-term exposure to stress—may explain mortality-rate disparities among non-Hispanic Black (Black) men. We aimed to investigate AL among Black men with equivalent education status after controlling for income. A cross-sectional study was employed to investigate AL among 4113 Black men who participated in the National Health and Nutrition Examination Survey between 1999–2018. A summation of 8 biomarker factors were used to compute AL, differences in socio-demographic characteristics by education status were evaluated, and health behaviors that may influence AL were examined. To determine the high-risk thresholds for each AL component, we examined each component’s distribution among NHB men for whom complete biomarker data were available in the NHANES sample. High-risk thresholds were determined as either (1) above the 75th percentile for body mass index (BMI), diastolic blood pressure (DBP), glycated hemoglobin, systolic blood pressure (SBP), total cholesterol, and serum triglycerides; or (2) below the 25th percentile for serum albumin and serum creatinine. Modified Poisson regression models were used to estimate prevalence ratios and their associated 95% confidence intervals for high AL risk while adjusting for potential confounders. Black men with a high school diploma/GED had a greater prevalence of high AL compared with Black men who had other levels of education, and a slightly higher prevalence of high AL compared with Black men who had less than a high school education. Black men with college degrees had a lower prevalence of high AL than Black men with the lowest levels of educational attainment. Researchers must further examine the hidden costs stemming from the interplay between discrimination associated with being Black in America and systemic racism in the educational system—which may be preventing Black men from achieving optimal health.

Examining educational attainment and allostatic load in non-Hispanic Black women

Background

Research suggests that non-Hispanic Black (henceforth, Black) women and people with lower educational attainment have higher levels of allostatic load (AL). This study sought to determine the association between educational attainment and AL among a large sample of Black women.

Methods

We analyzed data among 4177 Black women from the National Health and Nutrition Examination Survey years 1999–2018. AL score was defined as the total for abnormal measures of eight biomarkers. We further categorized participants with AL score greater than or equal to 4 as having high AL. We calculated mean estimates of total allostatic load scores using generalized linear models. We performed modified Poisson Regression models with robust variance estimation to estimate prevalence ratios (PRs) of high allostatic load and their associated 95% confidence intervals (CIs) by educational attainment.

Results

Black women with a college degree or higher had the lowest prevalence of high allostatic load (31.8% vs. 42.7%, 36.3%, 36.6%), and age adjusted mean allostatic load scores (mean = 1.90 vs. mean = 2.34, mean = 1.99, mean = 2.05) when compared to Black women with less than a high school diploma, high school diploma or GED, and some college or associates degree respectively. Even after accounting for age, poverty-to-income ratio, smoking, congestive heart failure, and heart attack, Black college graduates had an 14.3% lower prevalence of high allostatic load (PR = 0.857, 95% CI 0.839–0.876) when compared to Black women with lower educational attainment.

Conclusions

Black women with a baccalaureate degree or higher educational attainment had lower allostatic load compared to Black women with less than a high school education. This finding further confirms higher education is a social determinant of health. Future research should explore differences in AL by more granular degree types.

Temporal Trends in Racial and Ethnic Disparities in Endovascular Therapy in Acute Ischemic Stroke

Introduction

Endovascular therapy (EVT) use increased following clinical trials publication in 2015, but limited data suggest there may be persistent race and ethnicity differences.

Methods and Results

We included all patients with acute ischemic stroke arriving within 6 hours of last known well and with National Institute of Health Stroke Scale (NIHSS) score ≥6 between April 2012 and June 2019 in the Get With The Guidelines‐Stroke database and evaluated the association between race and ethnicity and EVT use and outcomes, comparing the era before versus after 2015. Of 302 965 potentially eligible patients; 42 422 (14%) underwent EVT. Although EVT use increased over time in all racial and ethnic groups, Black patients had reduced odds of EVT use compared with non‐Hispanic White (NHW) patients (adjusted odds ratio [aOR] before 2015, 0.68 [0.58‒0.78]; aOR after 2015, 0.83 [0.76‒0.90]). In‐hospital mortality/discharge to hospice was less frequent in Black, Hispanic, and Asian patients compared with NHW. Conversely discharge home was more frequent in Hispanic (29.7%; aOR, 1.28 [1.16‒1.42]), Asian (28.2%; aOR, 1.23 [1.05‒1.44]), and Black (29.1%; aOR, 1.08 [1.00‒1.18]) patients compared with NHW (24%). However, at 3 months, functional independence (modified Rankin Scale, 0–2) occurred less frequently in Black (37.5%; aOR, 0.84 [0.75‒0.95]) and Asian (33%; aOR, 0.79 [0.65‒0.98]) patients compared with NHW patients (38.1%).

Conclusions

In a large cohort of patients treated with EVT, Black versus NHW patient disparities in EVT use have narrowed over time but still exist. Discharge related outcomes were slightly more favorable in racial and ethnic underrepresented groups; 3‐month functional outcomes were worse but improved across all groups with time.
