Integrative approaches to methods training for early-career scientists: Rationale and process evaluation of the first cohort of the Michigan Integrative Well-Being and Inequality Training Program. J Clin Transl Sci 2023; 7:e169. [PMID: 37588674 PMCID: PMC10425869 DOI: 10.1017/cts.2023.595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 06/10/2023] [Accepted: 07/12/2023] [Indexed: 08/18/2023] Open
Abstract
Background The Michigan Integrative Well-Being and Inequality (MIWI) Training Program aims to provide state-of-the-art, interdisciplinary training to enhance the methodological skills of early-career scientists interested in integrative approaches to understanding health disparities. The goals of this paper are to describe the scientific rationale and core design elements of MIWI, and to conduct a process evaluation of the first cohort of trainees (called "scholars") to complete this program. Methods Mixed methods process evaluation of program components and assessment of trainee skills and network development of the first cohort (n = 15 scholars). Results The program drew 57 applicants from a wide range of disciplines. Of the 15 scholars in the first cohort, 53% (n = 8) identified as an underrepresented minority, 60% (n = 9) were within 2 years of completing their terminal degree, and most (n = 11, 73%) were from a social/behavioral science discipline (e.g., social work, public health). In the post-program evaluation, scholars rated their improvement in a variety of skills on a one (not at all) to five (greatly improved) scale. Areas of greatest growth included being an interdisciplinary researcher (mean = 4.47), developing new research collaborations (mean = 4.53), and designing a research study related to integrative health (mean = 4.27). The qualitative process evaluation indicated that scholars reported a strong sense of community and that the program broadened their research networks. Conclusions These findings have implications for National Institutes of Health (NIH) efforts to train early-career scientists, particularly from underrepresented groups, working at the intersection of multiple disciplines and efforts to support the formation of research networks.

Abstract
Racism drives population health inequities by shaping the unequal distribution of key social determinants of health, such as socioeconomic resources and exposure to stressors. Research on interrelationships among race, socioeconomic resources, stressors, and health has proceeded along two lines that have largely remained separate: one examining differential effects of socioeconomic resources and stressors on health across racialized groups (moderation processes), and the other examining the role of socioeconomic resources and stressors in contributing to racial inequities in health (mediation processes). We conceptually and analytically integrate these areas using race theory and a novel moderated mediation approach to path analysis to formally quantify the extent to which an array of socioeconomic resources and stressors-collectively and individually-mediate racialized health inequities among a sample of older adults from the Health and Retirement Study. Our results yield theoretical contributions by showing how the socioeconomic status-health gradient and stress processes are racialized (24% of associations examined varied by race), substantive contributions by quantifying the extent of moderated mediation of racial inequities (approximately 70%) and the relative importance of various social factors, and methodological contributions by showing how commonly used simple mediation approaches that ignore racialized moderation processes overestimate-by between 5% and 30%-the collective roles of socioeconomic status and stressors in accounting for racial inequities in health.

Abstract
For more than a century, substantial racial and ethnic inequities in perinatal health outcomes have persisted despite technical clinical advances and changes in public health practice that lowered the overall incidence of morbidity. Race is a social construct and not an inherent biologic or genetic reality; therefore, racial differences in health outcomes represent the consequences of structural racism or the inequitable distribution of opportunities for health along racialized lines. Clinicians and scientists in obstetrics and gynecology have a responsibility to work to eliminate health inequities for Black, Brown, and Indigenous birthing people, and fulfilling this responsibility requires actionable evidence from high-quality research. To generate this actionable evidence, the research community must realign paradigms, praxis, and infrastructure with an eye directed toward reproductive justice and antiracism. This special report offers a set of key recommendations as a roadmap to transform perinatal health research to achieve health equity. The recommendations are based on expert opinion and evidence presented at the State of the Science Research Symposium at the 41st Annual Pregnancy Meeting of the Society for Maternal-Fetal Medicine in 2021. Recommendations fall into 3 broad categories-changing research paradigms, reforming research praxis, and transforming research infrastructure-and are grounded in a historic foundation of the advances and shortcomings of clinical, public health, and sociologic scholarship in health equity. Changing the research paradigm requires leveraging a multidisciplinary perspective on structural racism; promoting mechanistic research that identifies the biologic pathways perturbed by structural racism; and utilizing conceptual models that account for racism as a factor in adverse perinatal outcomes. Changing praxis approaches to promote and engage multidisciplinary teams and to develop standardized guidelines for data collection will ensure that paradigm shifts center the historically marginalized voices of Black, Brown, and Indigenous birthing people. Finally, infrastructure changes that embed community-centered approaches are required to make shifts in paradigm and praxis possible. Institutional policies that break down silos and support true community partnership, and also the alignment of institutional, funding, and academic publishing objectives with strategic priorities for perinatal health equity, are paramount. Achieving health equity requires shifting the structures that support the ecosystem of racism that Black, Brown, and Indigenous birthing people must navigate before, during, and after childbearing. These structures extend beyond the healthcare system in which clinicians operate day-to-day, but they cannot be excluded from research endeavors to create the actionable evidence needed to achieve perinatal health equity.

Abstract
This qualitative study examines how the "Strong Black Woman" (SBW) label can have potentially negative health effects for African American/Black women that contribute to eating disorders. This study addresses the gap in literature on racial disparities that are present in understanding eating disorders that contribute to obesity and obesityrelated issues. Through semi-structured individual interviews conducted with (N = 11) Black female higher education students, participants were able to discuss how disorganized overeating patterns were associated with the emotional stress of being labeled a Strong Black Woman. Findings provide implications to clinicians, educators, and researchers by identifying stress inducing factors heightened by racist and sexist microaggressions that contribute to the mental and physical health of Black women. This study also adds to the limited literature on the intersection of racism and sexism that contribute to poor health outcomes in Black women.

Abstract
Quantitative studies of racial health disparities often use static measures of self-reported race and conventional regression estimators, which critics argue is inconsistent with social-constructivist theories of race, racialization, and racism. We demonstrate an alternative counterfactual approach to explain how multiple racialized systems dynamically shape health over time, examining racial inequities in cardiometabolic risk in the National Longitudinal Study of Adolescent to Adult Health. This framework accounts for the dynamics of time-varying confounding and mediation that is required in operationalizing a "race" variable as part of a social process (racism) rather than a separable, individual characteristic. We decompose the observed disparity into three types of effects: a controlled direct effect ("unobserved racism"), proportions attributable to interaction ("racial discrimination"), and pure indirect effects ("emergent discrimination"). We discuss the limitations of counterfactual approaches while highlighting how they can be combined with critical theories to quantify how interlocking systems produce racial health inequities.

Abstract
BACKGROUND AND OBJECTIVES Prior research documents accelerated physiological aging among African Americans due to their greater lifetime exposure to social and economic adversity. Yet, less is known about the mechanisms through which early life stressors, such as early life racial discrimination (ELRD), and later life psychosocial resources, such as racial centrality (i.e., importance of Black identity to one's sense of self), interact to shape allostatic load (AL) in adulthood. We evaluate the life course processes linking ELRD, adult racial centrality, and adult AL among older African Americans. RESEARCH DESIGN AND METHODS Data from the Nashville Stress and Health Study included African Americans aged 50 and older (N = 260). Poisson regression models assessed the links between ELRD, adult centrality, and adult AL. Interactions determined whether ELRD conditions the centrality-AL association in adulthood. RESULTS Adolescent ELRD conferred significantly higher levels of adult centrality and 32% increased risk of high adult AL. Greater adult centrality was linked to high adult AL, but the ELRD-adult AL association was not explained by centrality. However, ELRD and centrality interact to shape adult AL, such that racial centrality was protective against high adult AL for those who experienced racial discrimination as children or adolescents. DISCUSSION AND IMPLICATIONS Findings highlight the multiple pathways through which racism-related stressors and psychosocial resources interact to shape physiological dysregulation in later life and underscore the health significance of racial identity for older African Americans. Clinicians and public health professionals should assess early life stressors and foster psychosocial resilience to promote healthy aging.

Abstract
There is a well-established link between psychosocial risks and psychological health among African American (AA) men. Yet, the psychosocial sources and physical health consequences of resilience (i.e., the ability to maintain good health despite adversity) remain underexplored. Using data from 283 AA men in the Nashville Stress and Health Study, the present study investigated the links between psychosocial resilience and allostatic load (AL), a biological indicator of physiological dysregulation. Latent class analysis (LCA) identified distinct resilience profiles comprising eight psychosocial resources across four categories: coping strategies, sense of control, racial identity, and social support. Analysis of variance (ANOVA) tests determined significant class differences in men’s AL scores. LCA results confirm a four-class model was the best fit: Class 1 (high resources, 32%), Class 2 (high coping but low control, 13%), Class 3 (low resources but high racial identity, 20%), and Class 4 (low resources but high mastery, 34%). Results reveal lower AL (better health) among Classes 1 (m = 0.35) and 4 (m = 0.31) and higher AL (worse health) among Classes 2 (m = 0.44) and 3 (m = 0.44). Findings indicate that the “quality” rather than the “quantity” of psychosocial resources matters for physical health among AA men, as positive health outcomes were observed among both low- and high-resource classes. Results suggest different resource combinations produce distinct patterns of resilience among AA men and underscore the need to further elucidate complex resilience processes among this population.

Abstract
The United States lags in life expectancy compared to most of the world's similarly wealthy nations, driven by pronounced regional disparities particularly between the South and the rest of the country. The U.S. South has a violent history of lynchings of Black Americans by White mobs after the ending of slavery and up to the Civil Rights Era. Building on critical race scholarship, the objective of this study was to determine whether there exists an association between historical lynchings and overall life expectancies in the U.S. South. We created a cross-sectional county-level data set with 1221 data points utilizing data from the Equal Justice Initiative and Robert Wood Johnson Foundation Country Health Rankings. The average life expectancy for 2019-2020 was 76.1 years, ranging from 68.2 years to 90.2 years. Overall life expectancy was found to be highest (76.6) in counties with no recorded lynchings, and lowest (75.5) in counties with the most lynchings (p < .001). In the spatially enabled regression model, the history of lynching along with other covariates explained 57.1% of the variance in life expectancies across the study area. Counties with a history of lynchings also score lower compared to the reference group in various socioeconomic indicators, including median household incomes and high school graduation rates. The findings suggest that lynchings were pivotal in creating the social and physical environment affecting health outcomes in the U.S. South today. We call for further public health research which acknowledges and explores this form of violent and institutional anti-Black racism as foundational to the nation's regional health disparities.

Abstract
Objectives Health studies of structural racism/discrimination have been animated through the deployment of neighborhood effects frameworks that engage institutionalist concerns about sociopolitical resources and mobility structures. This study highlights the acute illness risks of place-based inequalities and neighborhood-varying race-based inequalities by focusing on access to and the regulation of mortgage markets. Design By merging neighborhood data on lending processes from the Home Mortgage Disclosure Act with individual health from the Project on Human Development in Chicago Neighborhoods, this article evaluates the acute childhood illness risks of four mutually inclusive, political economies using multilevel generalized linear models. Setting Chicago, IL, USA. Participants Youth aged 0 to 17 years. Main Outcome Measures The prevalence of 11 acute illnesses (cold/flu, sinus trouble, sore throat/tonsils, headache, upset stomach, bronchitis, skin infection, pneumonia, urinary tract infections, fungal disease, mononucleosis) and the past-year frequencies of 6 acute illnesses (cold/flu, sinus trouble, sore throat/tonsils, headache, upset stomach, bronchitis) are evaluated. Methods Multilevel logistic regression. Results The most theoretically consistent predictor of illness is a measure identifying neighborhoods with above-city-median levels of racial disparities in the regulation of loans - a mesolevel measure of structural racism. In areas with high levels of minority-White differences in less-regulated credit, youth are more likely to have a range of acute illnesses and experience them at more frequent intervals in the past year. Conclusions This article highlights the substantive and methodological importance of focusing on multidimensional representations of institutionalized political economic inequalities circumscribed and traversed by the power relations established by institutions and the state.

Abstract
Special Issue - Race reconciled II: Interpreting and communicating biological variation and race in 2021 Many sociocultural factors, like poverty and trauma, or homelessness versus a safe neighborhood, can get "under our skin" and affect our lives. These factors may also get "into our genes" through epigenetic changes that influence how genes are expressed. Changes in gene expression can further influence how we respond to sociocultural factors and how those factors impact our physical and mental health, creating a feedback loop between our sociocultural environment and our genome.

Abstract
Analyzing data from the 2015-2016 Indian Demographic and Health Survey (N = 41,768), we investigate how women's circulating glucose varies with the severity of intimate partner violence (IPV) they have experienced in the last year and how their likelihoods of corresponding noncommunicable diseases vary with IPV severity in their lifetime. Consistent with a physiological stress response, women who have recently experienced severe IPV exhibit higher glucose levels and are more likely to have extremely high levels-forewarning of disease development-than women who have not experienced IPV. Correspondingly, women who have ever experienced severe IPV in their lifetime have 33%-200% higher probabilities of diabetes, heart disease, thyroid disorders, and cancer and are 70% more likely to have any of these diseases and 175% more likely to have multiple than women who have experienced none.

Abstract
This study uses nationally representative data to extend a steadily growing body of research on the health consequences of skin color by comparatively examining the consequences of perceived ingroup and outgroup skin color discrimination (perceived colorism) for physical health among African Americans. Using a comprehensive set of measures of physical health, I find that perceived ingroup colorism is significantly associated with worse physical health outcomes among African Americans. Notably, the magnitude of ingroup colorism's associations with most of these outcomes rivals or even exceeds that of major lifetime discrimination, everyday discrimination, and perceived outgroup colorism. These findings compellingly suggest the inclusion of perceived colorism measures in future survey data collection efforts.

Abstract
Background In the United States, Black Americans are suffering from a significantly disproportionate incidence of COVID-19. Going beyond mere epidemiological tallying, the potential for racial-justice interventions, including reparations payments, to ameliorate these disparities has not been adequately explored. Methods We compared the COVID-19 time-varying Rt curves of relatively disparate polities in terms of social equity (South Korea vs. Louisiana). Next, we considered a range of reproductive ratios to back-calculate the transmission rates βi→j for 4 cells of the simplified next-generation matrix (from which R0 is calculated for structured models) for the outbreak in Louisiana. Lastly, we considered the potential structural effects monetary payments as reparations for Black American descendants of persons enslaved in the U.S. would have had on pre-intervention βi→j and consequently R0. Results Once their respective epidemics begin to propagate, Louisiana displays Rt values with an absolute difference of 1.3–2.5 compared to South Korea. It also takes Louisiana more than twice as long to bring Rt below 1. Reasoning through the consequences of increased equity via matrix transmission models, we demonstrate how the benefits of a successful reparations program (reflected in the ratio βb→b/βw→w) could reduce R0 by 31–68%. Discussion While there are compelling moral and historical arguments for racial-injustice interventions such as reparations, our study considers potential health benefits in the form of reduced SARS-CoV-2 transmission risk. A restitutive program targeted towards Black individuals would not only decrease COVID-19 risk for recipients of the wealth redistribution; the mitigating effects would also be distributed across racial groups, benefiting the population at large.

Background In the United States, Black Americans are suffering from significantly disproportionate incidence and mortality rates of COVID-19. The potential for racial-justice interventions, including reparations payments, to ameliorate these disparities has not been adequately explored. Methods We compared the COVID-19 time-varying R t curves of relatively disparate polities in terms of social equity (South Korea vs. Louisiana). Next, we considered a range of reproductive ratios to back-calculate the transmission rates β i→j for 4 cells of the simplified next-generation matrix (from which R 0 is calculated for structured models) for the outbreak in Louisiana. Lastly, we modeled the effect that monetary payments as reparations for Black American descendants of persons enslaved in the U.S. would have had on pre-intervention β i→j . Results Once their respective epidemics begin to propagate, Louisiana displays R t values with an absolute difference of 1.3 to 2.5 compared to South Korea. It also takes Louisiana more than twice as long to bring R t below 1. We estimate that increased equity in transmission consistent with the benefits of a successful reparations program (reflected in the ratio β b→b / β w→w ) could reduce R 0 by 31 to 68%. Discussion While there are compelling moral and historical arguments for racial injustice interventions such as reparations, our study describes potential health benefits in the form of reduced SARS-CoV-2 transmission risk. As we demonstrate, a restitutive program targeted towards Black individuals would not only decrease COVID-19 risk for recipients of the wealth redistribution; the mitigating effects would be distributed across racial groups, benefitting the population at large.

Abstract
BACKGROUND Enhanced understanding of spatial social polarization as a determinant of infant mortality is critical to efforts aimed at advancing health equity. Our objective was to identify associations between spatial social polarization and risk of infant death. METHODS We conducted a cross-sectional analysis of all birth records issued to non-Hispanic (NH) Black and White women in Wayne County, MI, from 2010 to 2013 (n = 84 159), including linked death records for deaths occurring at less than 1 year of age. Spatial social polarization was measured in each Census tract of maternal residence (n = 599) using the Index of Concentration at the Extremes (ICE)-a joint measure of racial and economic segregation-estimated from American Community Survey 2009-2013 data. Log-Poisson regression models quantified relative risk (RR) of infant death (all-cause and cause-specific) associated with tertiles of the index, adjusting for maternal demographic characteristics and tract-level poverty. RESULTS The crude infant-mortality rate was more than 2-fold higher among NH Black infants compared with NH Whites (14.0 vs 5.9 deaths per 1000 live births). Half of the 845 infant deaths (72% NH Black, 28% NH White) occurred in tracts in the lowest tertile of the ICE distribution, representing areas of relative deprivation. After adjustments, risk of death among infants in the lowest tertile was 1.46 times greater than those in the highest tertile (adjusted infant-mortality rate = 3.7 deaths per 1000 live births in highest tertile vs 5.4 deaths per 1000 live births in lowest tertile, relative risk = 1.46, 95% confidence interval = 1.02, 2.09). Patterns of associations with the index differed by cause of death. CONCLUSIONS These findings suggest efforts to support equitable community investments may reduce incidents of death and the disproportionate experience of loss among NH Black women.

Abstract
US Latino/as experience high rates of discrimination, resulting in personal and relational distress. A sample of 238 Latino/a young adults (Mage = 25.37 years; 57.6% men; 54.4% Mexican) was used to investigate how perceived discrimination was associated with romantic relationship instability via young adults' depressive symptoms. The moderating roles of ethnic identity and romantic relationship maintenance on these associations were examined. Greater relationship maintenance and ethnic identity affirmation were associated with less depression and relationship instability. Under conditions of high ethnic identity exploration and resolution, the association between discrimination and depressive symptoms was stronger, leading to greater relationship instability. The findings reveal that the protective roles of cultural and relational factors may depend on the stressor and outcomes examined.

Abstract
Prior research suggests that there are health benefits associated with marriage, although the physiological implications of marital status for women's health is less clear. Given that recent trends indicate that Black women are less likely to marry than White women, the goal of this study was to evaluate whether marital status accounts for racial differences in women's physical health. Using data from the Nashville Stress and Health Study (2011–2014), we estimated the probability of high allostatic load (AL), a biological indicator of physiological dysregulation, among women aged 18–69. We examined AL scores by race and marital status, evaluated the extent to which Black-White differences persisted after accounting for marital status, and assessed whether the racial disparity in AL varied across marital status groups. Results indicated that Black women had higher AL than White women, although racial differences in AL were not explained by marital status. In addition, marital status was a significant predictor of AL among Black, but not White women. Moreover, the racial disparity in AL was smallest among never married women and largest among currently and formally married women. Taken together, these findings suggest that Black-White inequalities in women's physical health are not explained by racial differences in marital status, despite the widening racial gap in marriage. Nevertheless, marital status may be an influential factor in shaping outcomes among Black women.

Abstract
This paper estimates the benefits of eliminating racial disparities in mortality rates and work weeks lost due to illness. Using data from the American Community Survey (2005–2007) and Minnesota vital statistics (2011–2015), we explore economic methodologies for estimating the costs of health disparities. The data reveal large racial disparities in both mortality and labor market non-participation arising from preventable diseases and illnesses. Estimates show that if racial disparities in preventable deaths were eliminated, the annualized number of lives saved ranges from 475 to 812, which translates into $1.2 billion to $2.9 billion per year in economic savings (in 2017 medical care inflation-adjusted dollars). After eliminating the unexplained racial disparities in labor market participation, an additional 4,217 to 9185 Minnesota residents would have worked each year, which equals $247.43 million to $538.85 million in yearly net benefits to Minnesota.

Abstract
OBJECTIVES We investigated the patterns of foreign-born Hispanic health convergence to U.S.-born Hispanics using an allostatic load index, a subjective biological risk health profile, and we explored whether the health convergence patterns differ by sex. METHODS The analytic sample consisted of 3,347 Hispanics from the pooled 2005-2010 National Health and Nutrition Examination Survey. We used negative binomial regression models to investigate the association between duration in the United States and the allostatic load index, while controlling for potential covariates. RESULTS Foreign-born Hispanics who had lived in the United States for 0-9 years and 10-19 years had lower levels of allostatic load than U.S.-born Hispanics; however, those who had lived in the United States for 20 or more years had a level of allostatic load similar to their U.S.-born counterparts. The pattern of immigrant health convergence shows a clear sex difference. In the sex-stratified models, we found that foreign-born Hispanic men converged to the level of allostatic load of U.S.-born Hispanic men after having lived in the United States for approximately 10 years. The health convergence pattern qualitatively differed for foreign-born Hispanic women, who remained healthier than U.S.-born Hispanic women regardless of duration in the United States. CONCLUSIONS Foreign-born Hispanics are healthier than their U.S.-born counterparts, providing support for the healthy migrant hypothesis. This relatively better health of foreign-born Hispanics disappears with a longer duration in the United States, providing support for the health convergence hypothesis, but is most noticeable for men. Foreign-born Hispanic women converge to U.S.-born Hispanic women's health status at a slower tempo, compared with foreign-born Hispanic men.

Abstract
BACKGROUND Behavioral health problems usually co-occur along with physical health problems, resulting in higher health care costs. These co-occurring conditions are likely to be more prevalent and serious among low income patients, affecting both the quality and costs of care. OBJECTIVE To examine the prevalence, severity, and health care costs of co-occurring chronic and behavioral health conditions among low income people compared with higher income people. METHODS Analysis of the 2011-2014 Medical Expenditure Panel Survey. Sample includes 146,000 persons aged 18-64 years. Regression analysis was used to examine how the combination of behavioral health conditions and chronic health conditions is associated with health care expenditures, and how this association differs by family income. RESULTS (1) Comorbid behavioral health problems are more prevalent and serious among low income people with chronic conditions compared with higher income people; (2) among patients with co-occurring chronic and behavioral problems, average annual spending is greater among the low income patients ($9472) compared with high income patients ($7457); (3) higher costs among low income patients with co-occurring conditions reflects their poorer mental and physical health, relative to higher income patients. CONCLUSIONS For many low income people, comorbid behavioral problems need to be understood in the social context in which they live. Simply screening low income people for behavioral health problems may not be sufficient unless there is greater understanding of the mechanisms that both cause and exacerbate chronic and behavioral health problems in the low income population.

Abstract
RATIONALE Previous research has identified long-term exposure to stress as a risk factor for negative mental and physical health outcomes. This pattern of findings suggests that environmental stimuli that evoke feelings of stress or strain may also result in physiological responses, which may accumulate over the life course and ultimately increase the overall risk of various physical health conditions. This physiological "wear and tear" resulting from sustained levels of stress or strain has been previously operationalized as allostatic load (AL), a comprehensive indicator of stress exposure. OBJECTIVE The current study examines the association between one potential environmental stressor-perceived inequality-and AL with a research design aimed at addressing both observed and unobserved sources of confounding; it also employs a more comprehensive AL measure (comprised of 24 biomarkers tapping seven physiological systems) than previous studies. METHOD The biomarker twin sample from the Midlife Development in the United States (MIDUS) study was used to estimate a series of twin comparison models, which include controls for latent sources of influence that cluster within families. The sibling comparison models also included additional controls for lifestyle choices, overall physical health, and demographics which may confound the examined associations. RESULTS The results revealed significant associations between greater perceptions of inequality and greater overall levels of AL. The association persisted even after including controls for both observed and unobserved influences that may confound the examined associations but was limited to more recent measures of perceived inequality. Associations involving earlier measures of perceived inequality, along with a lifetime measure, failed to reach conventional levels of significance. CONCLUSION Perceived inequality appears to be a robust predictor of AL and potentially contributes to subsequent physical health problems, particularly for more proximate forms of perceived inequality.

Abstract
A substantial gap remains between what we know about type 2 diabetes prevention and our ability to apply that knowledge in socially disadvantaged populations at highest risk. This gap results, in part, from a lack of integration between epidemiologic science and social psychology theory, particularly regarding the intersections of stress, self-regulatory health behaviors, and the biological mechanisms underlying the development of diabetes. In this commentary, we describe the utility of a theoretical framework that focuses on the intersection of biological, psychosocial, and environmental contexts as they apply to diabetes disparities, and how such a framework could inform a translational research agenda to reorient prevention efforts to address these inequalities. Such reorientation is needed to ensure that the implementation of prevention efforts does not inadvertently widen diabetes disparities.

Self-identified race, socially assigned skin tone, and adult physiological dysregulation: Assessing multiple dimensions of "race" in health disparities research. SSM Popul Health 2016; 2:595-602.

Abstract
Despite a general acceptance of “race” as a social, rather than biological construct in the social sciences, racial health disparities research has given less consideration to the dimensions of race that may be most important for shaping persistent disparities in adult physical health status. In this study, we incorporate the social constructionist view that race is multidimensional to evaluate the health significance of two measures of race, racial self-identification and the socially perceived skin tone of black Americans, in a sample of black and white adults in the Nashville Stress and Health Study (N=1186). First, we use the approach most common in disparities research—comparing group differences in an outcome—to consider self-identified racial differences in allostatic load (AL), a cumulative biological indicator of physical dysregulation. Second, we examine intragroup variations in AL among blacks by skin tone (i.e. light, brown, or dark skin). Third, we assess whether the magnitude of black-white disparities are equal across black skin tone subgroups. Consistent with prior research, we find significantly higher rates of dysregulation among blacks. However, our results also show that racial differences in AL vary by blacks’ skin tone; AL disparities are largest between whites and dark-skinned blacks and smallest between whites and light-skinned blacks. This study highlights the importance of blacks’ skin tone as a marker of socially-assigned race for shaping intragroup and intergroup variations in adult physiological dysregulation. These results demonstrate the importance of assessing multiple dimensions of race in disparities research, as this approach may better capture the various mechanisms by which “race” continues to shape health. Blacks have higher allostatic load (i.e. physiological dysregulation) than whites. Skin tone is a source of intragroup variation in allostatic load among blacks. Black-white differences in allostatic load vary by blacks’ perceived skin tone. Allostatic load disparity is smallest between whites and light-skinned blacks. Results show importance of self-identified and socially assigned race measures.

Abstract
As the social sciences expand their involvement in genetic and genomic research, more information is needed to understand how theoretical concepts are applied to genetic data found in social surveys. Given the layers of complexity of studying race in relation to genetics and genomics, it is important to identify the varying approaches used to discuss and operationalize race and identity by social scientists. The present study explores how social scientists have used race, ethnicity, and ancestry in studies published in four social science journals from 2000 to 2014. We identify not only how race, ethnicity, and ancestry are classified and conceptualized in this growing area of research, but also how these concepts are incorporated into the methodology and presentation of results, all of which structure the discussion of race, identity, and inequality. This research indicates the slippage between concepts, classifications, and their use by social scientists in their genetics-related research. The current study can assist social scientists with clarifying their use and interpretations of race and ethnicity with the incorporation of genetic data, while limiting possible misinterpretations of the complexities of the connection between genetics and the social world.

Abstract
BACKGROUND Cancer disparities are associated with a broad range of sociocultural determinants of health that operate in community contexts. High-risk populations may be more vulnerable to social and environmental factors that lead to chronic stress. Theoretical and empirical research indicates that exposure to contextual and sociocultural stress alters biological systems, thereby influencing cancer risk, progression, and, ultimately, mortality. OBJECTIVE We sought to describe contextual pathways through which stress likely increases cancer risk in high-risk, underserved populations. METHODS This review presents a description of the link between contextual stressors and disease risk disparities within underserved communities, with a focus on 1) stress as a proximal link between biological processes, such as cytokine responses, inflammation, and cancer and 2) stress as a distal link to cancer through biobehavioral risk factors such as poor diet, physical inactivity, circadian rhythm or sleep disruption, and substance abuse. These concepts are illustrated through application to populations served by three National Cancer Institute-funded Community Networks Program Centers (CNPCs): African Americans in the Deep South (the South Carolina Cancer Disparities Community Network [SCCDCN]), Native Hawaiians ('Imi Hale-Native Hawaiian Cancer Network), and Latinos in the Lower Yakima Valley of Washington State (The Center for Hispanic Health Promotion: Reducing Cancer Disparities). CONCLUSIONS Stress experienced by the underserved communities represented in the CNPCs is marked by social, biological, and behavioral pathways that increase cancer risk. A case is presented to increase research on sociocultural determinants of health, stress, and cancer risk among racial/ethnic minorities in underserved communities.

[PMID: 25884852 PMCID: PMC4340096 DOI: 10.1186/s12889-015-1462-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2014] [Accepted: 01/26/2015] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND A 2011 report by the Oregon Health Authority and the Department of Human Services documented disparities in its Latino and American Indian populations on multiple individual-level health indicators. However, research is lacking on the social contexts in which Latinos and American Indians in Oregon live and how these environments influence the health of communities as a whole. To help fill this gap, this study sought to contextualize the social environments that influence the health of Latinos and American Indian residents in three Oregon communities. METHODS Guided by an ecological framework, we conducted one-time semi-structured qualitative interviews with 26 study participants to identify the prominent health-related issues in the communities and to examine the factors that study participants perceived as enabling or inhibiting healthy lifestyles of community residents. We used a grounded theory approach to perform content and thematic analyses of the data. RESULTS Study participants identified preventable chronic conditions, such as diabetes, obesity, and hypertension, as the most pressing health concerns in their communities. Results showed that traditional and cultural activities and strong family and community cohesion were viewed as facilitators of good community health. Poverty, safety concerns, insufficient community resources, and discrimination were perceived as barriers to community health. Three themes emerged from the thematic analyses: social connectedness is integral to health; trauma has an ongoing negative impact on health; and invisibility of residents in the community underlies poor health. CONCLUSIONS This study's findings provide insight to the social contexts which operate in the lives of some Latinos and American Indians in Oregon. While participants identified community-level factors as important to health, they focused more on the social connections of individuals to each other and the relationships that residents have with their communities at-large. Our findings may also help to explain how the intra- and inter-personal levels, the community/institutional level, and the macro level/public policy contexts can serve to influence health in these communities. For example, trauma and invisibility are not routinely examined in community health assessment and improvement planning activities; nonetheless, these factors appear to be at play affecting the health of residents.

Abstract
INTRODUCTION Historical trauma (HT) is a collective trauma inflicted on a group of people who share an identity or affiliation, and is often characterized by the transgenerational legacy of traumatic experiences, and expressed through various psychological and social responses. This construct is proposed in contrast to post-traumatic stress disorder (PTSD) due to limitations identified with the latter diagnostic category when addressing collective trauma, especially in situations of political and social violence. The purpose of this article is to review the literature published so far on HT. METHODS A search was performed using the terms "historical trauma" and "mental health" or "trauma histórico" and "salud mental" in the scientific databases, EMBASE, Ebscohost, JSTOR, ProQuest, LILACS, SciELO, PsycARTICLES, ISI Web of Science and PubMed. RESULTS The authors reviewed HT definition, paramount characteristics of its traumatic experience, and several theories of on the transgenerational succession if these experiences occur, as well as possible consequences of traumatic events at individual, family and social level. Common characteristics of different therapeutic models are highlighted, in addition to some recommendations for their application. CONCLUSIONS PTSD has clear limitations in addressing community and cumulative traumatic experiences related to specific social and historical contexts. The authors discuss the potential utility of HT in this task. Finally, several gaps in current knowledge regarding this construct are mentioned, and some recommendations for future research are indicated.

Abstract
Current scholarly research, both sociologically and biologically based, continues to be inundated with notions of race operating as a biological construct and as a proxy for poor health outcomes. Medical research and practice have fostered an environment where diagnostics, treatment, and the creation and dissemination of drug regimens often are influenced by a patient's skin color and ethnicity. The emergence of biological markers in social science-based surveys has fueled recent health disparities research that is shaping the meaning, interpretation, and policy of the health of people of color. Using hypertension as an example, this paper focuses on ways in which biological markers are discussed within the realm of health in the African diaspora. Additionally, the paper discusses how the quantification of disease etiology devoid of social and historical contexts can be troubling to both the social science and medical fields. Finally, the paper identifies the ways in which black scholars can shape the conversation of health inequity in future research. The notion of "racial diseases"-that people of different races suffer from peculiar diseases and experience common diseases differently-is centuries old. It is tied to the original use of biology in inventing the political category of race. -Dorothy Roberts, Fatal Invention.

Abstract
Theories of historical trauma increasingly appear in the literature on individual and community health, especially in relation to racial and ethnic minority populations and groups that experience significant health disparities. As a consequence of this rapid growth, the literature on historical trauma comprises disparate terminology and research approaches. This critical review integrates this literature in order to specify theoretical mechanisms that explain how historical trauma influences the health of individuals and communities. We argue that historical trauma functions as a public narrative for particular groups or communities that connects present-day experiences and circumstances to the trauma so as to influence health. Treating historical trauma as a public narrative shifts the research discourse away from an exclusive search for past causal variables that influence health to identifying how present-day experiences, their corresponding narratives, and their health impacts are connected to public narratives of historical trauma for a particular group or community. We discuss how the connection between historical trauma and present-day experiences, related narratives, and health impacts may function as a source of present-day distress as well as resilience.

Abstract
BACKGROUND Leukocyte telomere length (LTL) is an indicator of general systemic aging, with shorter LTL being associated with several chronic diseases of aging and earlier mortality. Identifying factors related to LTL among African Americans may yield insights into mechanisms underlying racial disparities in health. PURPOSE To test whether the combination of more frequent reports of racial discrimination and holding a greater implicit anti-black racial bias is associated with shorter LTL among African-American men. METHODS Cross-sectional study of a community sample of 92 African-American men aged between 30 and 50 years. Participants were recruited from February to May 2010. Ordinary least squares regressions were used to examine LTL in kilobase pairs in relation to racial discrimination and implicit racial bias. Data analysis was completed in July 2013. RESULTS After controlling for chronologic age and socioeconomic and health-related characteristics, the interaction between racial discrimination and implicit racial bias was significantly associated with LTL (b=-0.10, SE=0.04, p=0.02). Those demonstrating a stronger implicit anti-black bias and reporting higher levels of racial discrimination had the shortest LTL. Household income-to-poverty threshold ratio was also associated with LTL (b=0.05, SE=0.02, p<0.01). CONCLUSIONS Results suggest that multiple levels of racism, including interpersonal experiences of racial discrimination and the internalization of negative racial bias, operate jointly to accelerate biological aging among African-American men. Societal efforts to address racial discrimination in concert with efforts to promote positive in-group racial attitudes may protect against premature biological aging in this population.

Abstract
PURPOSE There is growing evidence that racial, ethnic, and socioeconomic status (SES) differentials in health emerge early in life. This study provided a descriptive profile of allostatic load (AL) among adolescents, focusing on sociodemographic correlates and variation in age patterns of AL by race and ethnicity. Allostatic load, an index of cumulative physiological dysregulation, is a construct that measures how individuals' interactions with their environment "get under the skin" to influence health. METHODS We used data from 8,052 adolescents ages 12-19 years, from the United States National Health and Nutrition Examination Survey 1999-2008. A summary measure of AL was assessed with biomarkers representing cardiovascular, inflammatory, and metabolic systems. Weighted univariate, bivariate, and multivariable negative binomial regression statistics were employed. RESULTS Mean AL increased with age, was higher for blacks than whites or Mexican-Americans, and was higher among adolescents of lower SES. Although black adolescents had higher AL for all ages, the relative advantage of whites and Mexican-Americans declined with age. CONCLUSIONS Racial and SES inequalities in AL exist during adolescence. These findings contribute to the understanding of how early life adverse factors "get under the skin," and are potentially translated into disease outcomes and health disparities later in life.

Abstract
A growing empirical literature in economics and sociology documents the existence of differences in social and economic outcomes between mixed-race blacks and other blacks . However, few researchers have considered whether the advantages associated with mixed-race status may have also translated into differences in mortality outcomes between subgroups of blacks and how both groups compared to whites. We employ previously untapped 1880 North Carolina Mortality census records in conjunction with data from the 1880 North Carolina Population Census to examine whether mulatto, or mixed-race blacks may have experienced mortality advantages over to their colored, or non-mixed race counterparts. For men between the ages of 20-44, estimates demonstrate that all black males are more likely than whites to die. Although our results indicate that there are no statistically significant differences in mortality between mulatto and colored blacks, there are some indications that mulatto males may have enjoyed a slight mortality advantage compared to their colored counterparts. However, we find a substantial mortality advantage associated with mixed-race status among women. These findings indicate that mixed-race women, rather than men, may have accrued any mortality advantages associated with color and white ancestry.

Abstract
This article addresses conceptual and methodological aspects of the relations between discrimination and health from an epidemiological perspective. Definitions of discrimination and related constructs are reviewed, and the main theories underlying their association with health are presented. Scales developed to assess discrimination are discussed, in conjunction with a new instrument, devised to operationalize the concept in Brazilian epidemiological surveys. As a relatively unpredictable and uncontrollable source of psychosocial stress, discrimination has been consistently associated with adverse health outcomes and behaviors, particularly mental disorders, smoking, and alcohol use. However, progress in the area depends partly on dealing with aspects related to the assessment of the phenomenon, such as the definition of a construct map and simultaneous measurement of different types of discrimination. Research involving these aspects will enhance our understanding of discrimination and its health consequences, thus increasing our ability to reduce its social occurrence.

Abstract
We investigate whether school racial composition is associated with racial and ethnic differences in early adult health. We then examine whether perceived discrimination, social connectedness, and parent support attenuates this relationship. Using U.S. data from Waves I and IV of the National Longitudinal Survey of Adolescent Health, we found that black adolescents attending predominantly white schools reported poorer adult health while Asians reported better health. Further research is warranted to understand whether there are qualitative differences in the treatment of racial and ethnic minorities within certain school contexts and how that differential treatment is related to adult health outcomes.

Abstract
The concept of allostasis suggests that greater cumulative stress burden can influence stress-responsive physiology. Dysregulation of allostatic mediators, including the hypothalamic-pituitary-adrenal (HPA) axis, is thought to precede many other signs of age-related pathology as the persistent burden of stressors accumulates over the individual's life span. We predicted that even in young adulthood, HPA regulation would differ between Blacks and Whites, reflecting, in part, higher rates of stressor exposure and greater potential for stressors to "get under the skin." We examined whether stressor exposure, including experiences with racism and discrimination, explained race differences in waking cortisol and the diurnal rhythm. We also examined whether HPA functioning was associated with mental health outcomes previously linked to cortisol. Salivary cortisol was assayed in 275 young adults (127 Blacks, 148 Whites, 19 to 22 years old), four times a day across 3 days. Hierarchical linear models revealed flatter slopes for Blacks, reflecting significantly lower waking and higher bedtime cortisol levels compared to Whites. Associations of HPA functioning with stressors were typically more robust for Whites such that more stress exposure created an HPA profile that resembled that of Black young adults. For Blacks, greater stressor exposure did not further impact HPA functioning, or, when significant, was often associated with higher cortisol levels. Across both races, flatter slopes generally indicated greater HPA dysregulation and were associated with poor mental health outcomes. These differential effects were more robust for Whites. These findings support an allostatic model in which social contextual factors influence normal biorhythms, even as early as young adulthood.
