Perceived racial discrimination and hypertension: a comprehensive systematic review

Working Together with God: Religious Coping, Perceived Discrimination, and Hypertension

This study examined the relationships of perceived discrimination and religious coping with hypertension in a sample of Black and White Seventh-day Adventists. Data come from a community-based sample of 6128 White American, 2253 African American and 927 Caribbean American adults (67% women; mean age = 62.9 years). Results indicate lifetime unfair treatment was significantly associated with hypertension regardless of race/ethnicity. Positive religious coping was associated with lower odds of hypertension and did not interact with unfair treatment. Both positive and negative religious coping were indirectly associated with increased hypertension risk through an increase in perceived discrimination.

Heart Disease and Stroke Statistics-2020 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals.

RESULTS

Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

The Association Between Perceived Racial Discrimination and Hypertension in a Low-Income, Racially Integrated Urban Community

We examined the association between perceived racial discrimination and hypertension among African Americans and whites who live in a low-income, racially integrated, urban community. Hypertension was defined as having a systolic blood pressure 140 mm Hg or more, a diastolic blood pressure 90 mm Hg or more, or taking antihypertensive medication(s). Perceived racial discrimination was based on self-reported responses of experiencing racial discrimination in various settings. Using modified Poisson multivariable regression models, we found no association between perceived racial discrimination and hypertension (prevalence ratio: 0.96, 95% confidence interval: 0.90-1.04). Findings suggest that social context may play a role in the relationship between perceived racial discrimination and hypertension.

Interactive Relations Across Dimensions of Interpersonal-Level Discrimination and Depressive Symptoms to Carotid Intimal-Medial Thickening in African Americans

OBJECTIVE

This study aimed to examine within-race interactions of multiple dimensions of self-reported discrimination with depressive symptoms in relation to carotid intimal-medial thickness (IMT), a subclinical marker of atherosclerosis prospectively implicated in stroke incidence, in middle-aged to older African American and white adults.

METHODS

Participants were a socioeconomically diverse group of 1941 African Americans (56.5%) and whites from the Healthy Aging in Neighborhoods of Diversity across the Life Span study (30-64 years old, 47% men, 45.2% with household income <125% federal poverty threshold) who underwent carotid IMT measurement. Discrimination was assessed across four dimensions (everyday, frequency across various social statuses, racial, and lifetime burden). The Center for Epidemiologic Studies Depression scale was used to assess depressive symptoms.

RESULTS

In cross-sectional hierarchical regression analyses, two interactions were observed in African Americans: more frequent discrimination across various social statuses (b < 0.001, p = .006) and a higher lifetime discrimination burden (b < 0.001, p = .02) were each related to thicker carotid IMT in those with greater depressive symptoms. No significant findings were observed within whites.

CONCLUSIONS

Among African Americans, those reporting high levels of discrimination and depressive symptoms have increased carotid atherosclerosis and may be at greater risk for clinical end points compared with those reporting one or neither of these risk factors. Findings suggest that assessment of interactive relationships among social and psychological factors may elucidate novel pathways for cardiovascular disease, including stroke, among African Americans.

Assessing the Role of Health Behaviors, Socioeconomic Status, and Cumulative Stress for Racial/Ethnic Disparities in Obesity

OBJECTIVE

This study aimed to examine the explanatory role of health behaviors, socioeconomic position (SEP), and psychosocial stressors on racial/ethnic obesity disparities in a multiethnic and multiracial sample of adults.

METHODS

Using data from the Chicago Community Adult Health Study (2001-2003), Oaxaca-Blinder decomposition analysis was conducted to quantify the extent to which health behaviors (fruit and vegetable consumption and physical activity), SEP, and cumulative stressors (e.g., perceived discrimination, financial strain) each explained differences in obesity prevalence in Black, US-born Hispanic, and non-US-born Hispanic compared with non-Hispanic White participants.

RESULTS

SEP and health behaviors did not explain obesity differences between racial/ethnic minorities and White individuals. Having high levels of stress in four or more domains explained 4.46% of the differences between Black and White individuals, whereas having high levels of stress in three domains significantly explained 14.13% of differences between US-born Hispanic and White. Together, the predictors explained less than 20% of differences between any racial/ethnic minority group and White individuals.

CONCLUSIONS

Exposure to stressors may play a role in obesity disparities, particularly among Black and US-born Hispanic individuals. Other obesity-related risk factors need to be examined to understand the underlying mechanisms explaining obesity disparities.

Self-rated health of Middle Eastern immigrants in the US: a national study

OBJECTIVES

The aim of the study was to examine self-rated health (SRH) of Middle Eastern immigrants in the US compared with US-born non-Hispanic whites and to examine factors associated with fair/poor SRH among Middle Eastern immigrants in the US.

STUDY DESIGN

We used a cross-sectional design to analyze the National Health Interview Survey from 2001 to 2015.

METHODS

Secondary survey analysis procedures were conducted using the SAS program, with a total of 3,966 Middle Eastern and 731,285 US-born non-Hispanic whites. Descriptive statistics and regression analyses were used.

RESULTS

Middle Eastern immigrants had significantly higher rates of fair/poor SRH than US-born whites across the three survey waves. Reporting symptoms of serious psychological distress, older age (60+ years), current alcohol-drinking status, and having a family member with disability were the factors associated significantly with higher odds of reporting fair/poor SRH in Middle Eastern immigrants, whereas education was a protecting factor of fair/poor SRH.

CONCLUSIONS

This study indicates that Middle Eastern immigrants are one of the US immigrant populations that report poor health status, which reveals the need for health policy attention to reduce health disparities.

Understanding how discrimination can affect health

BACKGROUND

To provide an overview of the empirical research linking self-reports of racial discrimination to health status and health service utilization.

METHODS

A review of literature reviews and meta-analyses published from January 2013 to 2019 was conducted using PubMed, PsycINFO, Sociological Abstracts, and Web of Science. Articles were considered for inclusion using the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) framework.

RESULTS

Twenty-nine studies met the criteria for review. Both domestic and international studies find that experiences of discrimination reported by adults are adversely related to mental health and indicators of physical health, including preclinical indicators of disease, health behaviors, utilization of care, and adherence to medical regimens. Emerging evidence also suggests that discrimination can affect the health of children and adolescents and that at least some of its adverse effects may be ameliorated by the presence of psychosocial resources.

CONCLUSIONS

Increasing evidence indicates that racial discrimination is an emerging risk factor for disease and a contributor to racial disparities in health. Attention is needed to strengthen research gaps and to advance our understanding of the optimal interventions that can reduce the negative effects of discrimination.

Everyday Racial Discrimination and Hypertension among Midlife African American Women: Disentangling the Role of Active Coping Dispositions versus Active Coping Behaviors

Racial discrimination, a psychosocial stressor, may contribute to disproportionate rates of hypertension among African American women. Coping moderates the effects of psychosocial stress on health. Coping dispositions describe stable personality characteristics, whereas contextual frameworks emphasize flexible coping behaviors in response to specific stressful encounters. Using data from the African American Women's Heart and Health Study-a non-probability cross-section of 208 midlife African American women in Northern California-we estimated the association between everyday racial discrimination (Everyday Discrimination Scale, EDS) and prevalence of hypertension (HTN), and evaluated moderation by coping disposition (John Henryism Active Coping scale, JH) versus context-specific active coping behavior (Active Coping with Racism scale, ACR). There were no main associations between EDS, JH, or ACR on HTN prevalence. There was evidence of statistical interaction between EDS and ACR (p-int = 0.05), but not JH (p-int = 0.90). Among those with high levels of ACR, reporting monthly (prevalence ratio (PR) = 2.35, 95% confidence interval (CI) = 1.13, 4.87), weekly (PR = 2.15, 95% CI = 1.01, 4.61), or daily (PR = 2.36, 95% CI = 1.14, 4.88) EDS was associated with higher HTN prevalence, versus reporting racial discrimination yearly or less. In contrast, among those with low levels of ACR, reporting more chronic racial discrimination was associated with lower hypertension prevalence, although results were less precise. Findings suggest that ongoing active coping with chronic racial discrimination may contribute to hypertension risk among African American women.

CE: Original Research: Midlife Hypertension and Hypercholesterolemia in Relation to Cognitive Function Later in Life in Black Women

: Purpose: This study sought to evaluate midlife hypertension and hypercholesterolemia in relation to cognitive function later in life among black women.

METHODS

Participants were drawn from the Nurses' Health Study and the Women's Health Study databases. In these studies, health professionals reported health information by questionnaire at baseline and at regular follow-up intervals, including diagnoses of hypertension, hypercholesterolemia, or both; and they completed telephone-based cognitive assessments later in life. Multivariable-adjusted linear regression models were used to estimate mean differences in global cognition and executive function scores, comparing women with and without a history of hypertension at midlife and women with and without a history of hypercholesterolemia at midlife.

RESULTS

Data for 363 black female health professionals were analyzed. Those with a history of hypertension or hypercholesterolemia at midlife did not have lower global cognition and executive function scores later in life compared with those without such a history, although there were trends in this direction.

CONCLUSION

In the study sample, a history of hypertension or hypercholesterolemia at midlife was not related to worse cognitive function in later life. But there was a suggestive pattern of trends that warrants further exploration in larger studies.

Sex Differences in the Impact of Racial Discrimination on Mental Health Among Black Americans

PURPOSE OF REVIEW

Greater racial discrimination is associated with poorer mental health among Black Americans; yet, there remains an incomplete understanding of sex differences in exposure to racial discrimination, and further, of how sex differences in coping with racial discrimination may heighten or diminish risk for poorer mental health.

RECENT FINDINGS

Black men may experience greater exposure to both structural and communal forms of racial discrimination, whereas Black women may face both a wider range of potential sources, as well as encounter greater variability in the subjective experience of racial discrimination. For both Black women and men, racial discrimination may be similarly associated with maladaptive coping strategies (i.e., emotional eating, rumination) that also are linked to poorer mental health; however, emerging findings suggest that mindfulness may partially buffer these deleterious effects. Overall, the recent literature reveals mixed findings with respect to sex differences in the experience and negative mental health impact of racial discrimination. Despite this heterogeneity, evidence documents sex differences in the settings, type, and qualitative experience of racial discrimination among Black Americans. Additionally, growing evidence indicating that racial discrimination is associated with physiological markers of stress reactivity and psychopathology risk further bolsters its characterization as a unique form of chronic stress among Black Americans and other minority groups in the USA.

Barriers to equitable maternal health in Aotearoa New Zealand: an integrative review

BACKGROUND

The purpose of this review was to examine the literature for themes of underlying social contributors to inequity in maternal health outcomes and experiences in the high resource setting of Aotearoa New Zealand. These 'causes of the causes' were explored and compared with the international context to identify similarities and New Zealand-specific differences.

METHOD

A structured integrative review methodology was employed to enable a complex cross disciplinary analysis of data from a variety of published sources. This method enabled incorporation of diverse research methodologies and theoretical approaches found in the literature to form a unified overall of the topic.

RESULTS

Six integrated factors - Physical Access, Political Context, Maternity Care System, Acceptability, Colonialism, and Cultural factors - were identified as barriers to equitable maternal health in Aotearoa New Zealand. The structure of the maternal health system in New Zealand, which includes free maternity care and a woman centred continuity of care structure, should help to ameliorate inequity in maternal health and yet does not appear to. A complex set of underlying structural and systemic factors, such as institutionalised racism, serve to act as barriers to equitable maternity outcomes and experiences. Initiatives that appear to be working are adapted to the local context and involve self-determination in research, clinical outreach and community programmes.

CONCLUSIONS

The combination of six social determinants identified in this review that contribute to maternal health inequity is specific to New Zealand, although individually these factors can be identified elsewhere; this creates a unique set of challenges in addressing inequity. Due to the specific social determinants in Aotearoa New Zealand, localised solutions have potential to further maternal health equity.

Expectations of Racism and Carotid Intima-Media Thickness in African American Women

OBJECTIVE

Several researchers have argued that racism-related stressors play an important role in adverse cardiovascular outcomes among African American women. However, studies have primarily focused on experiences of racism; thus, the role of expectations of racism is insufficiently understood. The current proof-of-concept study was designed to examine associations among expectations of racism, self-reported experiences of racism, and carotid intima-media thickness (IMT), a marker of cardiovascular risk, in African American women.

METHODS

Participants were 52 healthy African American women, aged 30 to 50 years (M (SD) = 40.8 (4.3)). Expectations of racism were assessed with a modified version of the Race-Based Rejection Sensitivity Questionnaire, experiences of racism were assessed with the Schedule of Racist Events, and carotid IMT was measured using B-mode ultrasound.

RESULTS

In linear regression analyses adjusted for age, expectations of racism were associated with higher levels of carotid IMT (b = .04, SE = .014, p = .013), after adjusting for experiences of racism. Findings remained significant after additional adjustments for cardiovascular risk factors (b = .03, SE = .014, p = .032). Associations were not confounded by additional stressors, hostility, or negative affect (depressive symptoms).

CONCLUSIONS

Independent of actual reports of racism, "expectations" of racism may be associated with increased cardiovascular risk in African American women. In addition, although experiences of discrimination were associated with depressive symptoms, expectations of racism were not, suggesting that other negative emotions likely play a role. Future studies are needed to replicate these results in larger samples and to explore the psychological and physiological pathways through which expectations of racism might affect cardiovascular disease risk across a range of populations.

Black-White Marriages: The Moderating Role of Openness on Experience of Couple Discrimination and Marital Satisfaction

This study examined how open communication between spouses may buffer against discrimination experienced by Black-White couples. Results from 178 couples analyzed using a combination of common-fate and actor-partner interdependence models, indicated that for Black partners, marital satisfaction was not contingent on the level of openness when experiences of couple discrimination were low. When experiences of couple discrimination were high, levels of marital satisfaction were maintained among partners who reported high openness and reduced among partners who reported low openness. Moderation effects were not found for White partners. The results suggest that because Black partners are more aware of and sensitized to discrimination, White partners' abilities to attune to their partners' needs for support could help enhance their relationships.

Systematic Review of Chronic Discrimination and Changes in Biology During Pregnancy Among African American Women

Profound racial health disparities in maternal and infant health exist in the USA. Discrimination based on race may contribute to these disparities, but the biological pathways through which racial discrimination acts on health are not fully known. Even less is known about these pathways during development. Examining how racial discrimination becomes biology is paramount because it may shed light on how and when such social forces result in lasting biological consequences for health and wellbeing. To begin exploring this issue, we performed a systematic review of the relationships between experiences of chronic racial discrimination and relevant biomarkers measured during pregnancy among African American women. The literature search included studies published prior to August 2018 in the MEDLINE, Embase, and PsycINFO databases, and 11 studies met our inclusion criteria. We evaluated the articles based on the biological system that the authors investigated, which included the immune, neuroendocrine, and cardiovascular systems. We found that the current literature provides preliminary evidence that experiences of chronic racial discrimination are associated with changes in maternal biology during pregnancy. However, the literature was limited in both quantity and quality. We found only 11 studies that addressed this subject, four of which only provided indirect evidence, and many studies had small sample sizes. Future work in this area should develop more informative methods that consider the interaction between interpersonal and structural racial discrimination, individual variation, and sociocultural factors. We conclude researchers should continue to work in this area and focus on developing more effective study designs and larger sample sizes.

Perceived Discrimination and Cardiometabolic Risk Among US Hispanics/Latinos in the HCHS/SOL Sociocultural Ancillary Study

BACKGROUND

Metabolic syndrome (MetS) is a group of cardiovascular risk factors including elevated blood pressure, elevated triglycerides, decreased high-density lipoprotein cholesterol, impaired fasting glucose, and abdominal obesity, which disproportionately affects Hispanics/Latinos. The present study examined associations between perceived discrimination and MetS in Hispanic/Latino adults from various background groups (i.e., Dominican, Central American, Cuban, Mexican, Puerto Rican, South American).

METHODS

Data were obtained from 5174 Hispanics/Latinos who participated in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study. MetS components and covariates were measured at a baseline examination, and perceived discrimination was assessed within 9 months of baseline. Path analysis modeled associations of perceived discrimination with MetS prevalence and each of the six components of MetS, controlling for age, sex, income, acculturation, physical activity, diet, smoking, and alcohol use.

RESULTS

Among the full cohort, perceived discrimination was not associated with MetS prevalence in any of the models evaluated. Higher perceived discrimination at work/school was associated with larger waist circumference. When examining background groups separately, higher perceived ethnicity-associated threat was related to increased MetS prevalence only among individuals of Central American background. Differential patterns of association between perceived discrimination and MetS components were found for different background groups.

CONCLUSIONS

Overall results suggested that perceived discrimination was not strongly or consistently associated with MetS among Hispanics/Latinos.

Differential associations between everyday versus institution-specific racial discrimination, self-reported health, and allostatic load among black women: implications for clinical assessment and epidemiologic studies

PURPOSE

Black women have the highest estimated allostatic load (AL). AL and self-perceived health are strong health predictors and have been linked to racial discrimination. Research suggests that everyday and institution-specific racial discrimination may predict different AL and self-reported health (SRH) outcomes. Furthermore, discrepancies between AL and self-perceived health could widen disparities. We estimated associations between everyday versus institution-specific racial discrimination with AL and SRH.

METHODS

Data are from a San Francisco Bay Area community sample of 208 black women aged 30-50 years. Participation involved a questionnaire, self-interview, blood draw, and anthropometric measurements. Adjusted generalized linear regression models estimated associations of racial discrimination with AL and SRH.

RESULTS

After adjusting for age, socioeconomic position, and medication use, institution-specific discrimination was negatively associated with AL (i.e., better health), whereas everyday experiences showed no association. Those reporting very-high (vs. moderate) institution-specific discrimination had lower AL (β = -1.31 [95% CI: -2.41, -0.20]; AL range: 0-15). No racial discrimination-SRH association was found.

CONCLUSIONS

For black women, (1) institution-specific racial discrimination may be differentially embodied compared with everyday experiences and (2) institutional racism may contribute to physiologic stress-regulation regardless of self-perceived health status. Potential factors that may contribute to an inverse racial discrimination-AL association, and future research, are discussed.

Links between discrimination and cardiovascular health among socially stigmatized groups: A systematic review

BACKGROUND

There is a high prevalence of cardiovascular disease across diverse groups in the U.S. population, and increasing research has identified stigma as a potential barrier to cardiovascular disease prevention and treatment. This systematic review examines evidence linking discrimination and cardiovascular health among socially stigmatized groups.

STUDY DESIGN

Six databases were systematically reviewed from inception through February 2018 for studies with adult subjects, focusing on cardiovascular health indicators among social groups stigmatized because of their gender, race/ethnicity, age, body weight/obesity, or sexual orientation. The Newcastle-Ottawa Scale was used to evaluate the methodological quality and risk of bias for nonrandomized studies, and the Cochrane Collaboration 7-item domain for randomized controlled and experimental trials.

RESULTS

The search identified 84 eligible studies published between 1984 and 2017. Studies retrieved were categorized according to demonstrated links between stigma and cardiovascular disease risk factors including blood pressure (n = 45), heart rate variability (n = 6), blood/saliva cardiovascular biomarkers (n = 18), as well as other indicators of cardiovascular health (n = 15). Based on the findings from included studies, 86% concluded that there was a significant relationship among stigma or discrimination and cardiovascular health indicators among socially stigmatized groups. However, there were varying degrees of evidence supporting these relationships, depending on the type of discrimination and cardiovascular health indicator. The current evidence implies an association between perceived discrimination and cardiovascular health. However, a majority of these studies are cross-sectional (73%) and focus on racial discrimination (79%), while using a wide variety of measurements to assess social discrimination and cardiovascular health.

CONCLUSIONS

Future research should include longitudinal and randomized controlled trial designs, with larger and more diverse samples of individuals with stigmatized identities, using consistent measurement approaches to assess social discrimination and its relationship with cardiovascular health.

Risk of dementia and mild cognitive impairment among older adults in same-sex relationships

INTRODUCTION

Sexual minority discrimination might lead to a higher risk of mild cognitive impairment (MCI) and dementia. The aim of this study was to assess the risk of MCI and dementia between older adults in same-sex relationships (SSR) and opposite-sex relationships (OSR).

METHODS

We analyzed longitudinal data from the National Alzheimer's Coordinating Center up to September 2017. Analyses included cognitively normal individuals 55+ at baseline who had a spouse, partner, or companion as study partner at any assessment. Associations were calculated using survival analysis adjusting for demographics and APOE-e4 carrier status.

RESULTS

Hazard ratios of MCI and dementia did not differ statistically between SSR and OSR individuals in the total sample nor stratified by sex.

CONCLUSION

The lack of association between SSR and MCI and dementia warrants future research into their potential resilience mechanisms and the inclusion of sexual minority status questions in research and surveillance studies. The potential recruitment bias caused by nonprobabilistic sampling of the cohort and the reporting and ascertainment bias caused by using SSR to infer sexual minority status may have influenced our findings.

Triple jeopardy: the joint impact of racial segregation and neighborhood poverty on the mental health of black Americans

PURPOSE

Because segregation may shield blacks from discrimination as well as increase their exposure to concentrated poverty, its net impact on the mental well-being of black Americans is unclear. We investigated the intersection between segregation, neighborhood poverty, race, and psychological well-being.

METHODS

Using data from the nationally representative 2008-2013 National Health Interview Survey merged with U.S. Census data, we examined the association between black-white metropolitan segregation (D-index and P-index) and psychological distress (a binary indicator based on the Kessler 6 score ≥ 13) for blacks and whites. Furthermore, we assessed whether neighborhood poverty explains and/or modifies the association. Logistic regression models were estimated separately for blacks and whites as well as for each segregation index.

RESULTS

Higher D- and P-indices were associated with higher odds of psychological distress for blacks. Neighborhood poverty explained some, but not all, of the association. In models that allowed for the impact of metropolitan segregation to vary by neighborhood poverty, higher segregation was found to be detrimental for blacks who resided in high poverty neighborhoods but not for those living in low poverty neighborhoods. We found no evidence that segregation impacts the mental health of whites-either detrimentally or beneficially-regardless of neighborhood poverty level.

CONCLUSIONS

The impact of segregation differs by neighborhood poverty and race. The psychological harm of structural racism, resulting in segregation and concentrated poverty, is not additive but multiplicative, reflecting a "triple jeopardy" for blacks, whereby their mental health is detrimentally impacted by the compounded effects of both neighborhood distress and racial segregation.

Placing prostate cancer disparities within a psychosocial context: challenges and opportunities for future research

Black men are more likely to be diagnosed with prostate cancer compared with White men. Despite advances in prevention and treatment strategies, disparities in prostate cancer among Black men persist. While research on the causes of higher incidence and mortality is ongoing, there is limited evidence in the existing literature that clearly speaks to the potential psychological or social factors that may contribute to disparities in prostate cancer incidence. Given the lack of attention to this issue, we review scientific evidence of the ways in which social factors, including socioeconomic status and racial segregation, as well as psychological factors, like depression and anxiety, are related to subsequent prostate cancer risk, which could occur through behavioral and biological processes. Our objective is to illuminate psychosocial factors and their context, using a racial disparity lens, which suggests opportunities for future research on the determinants of prostate cancer. Ultimately, we aim to contribute to a robust research agenda for the development of new prostate cancer prevention measures to reduce racial disparities.

Racism and Health: Evidence and Needed Research

In recent decades, there has been remarkable growth in scientific research examining the multiple ways in which racism can adversely affect health. This interest has been driven in part by the striking persistence of racial/ethnic inequities in health and the empirical evidence that indicates that socioeconomic factors alone do not account for racial/ethnic inequities in health. Racism is considered a fundamental cause of adverse health outcomes for racial/ethnic minorities and racial/ethnic inequities in health. This article provides an overview of the evidence linking the primary domains of racism-structural racism, cultural racism, and individual-level discrimination-to mental and physical health outcomes. For each mechanism, we describe key findings and identify priorities for future research. We also discuss evidence for interventions to reduce racism and describe research needed to advance knowledge in this area.

Examining the service-related experiences and outcomes of caregivers involved in a system of care who experienced everyday discrimination

Individuals who report everyday experiences of discrimination are at heightened risk for adverse health outcomes and tend to report underutilization of health services. Systems of care (SOCs) have the potential to engage members of minority groups and to reduce health disparities. We examined the service-related experiences of predominantly Latinx caregivers enrolled in a SOC for their children with severe psychological health needs. We used independent samples t-tests and regression analyses to compare relations among service access, perceived service characteristics, and caregiver stress according to whether caregivers reported frequent or infrequent discrimination. The frequent discrimination group scored significantly higher on dimensions of stress and had greater dosage than the infrequent group. There were no differences in relations between service characteristics and outcomes by group. Findings indicated important differences in the service-related experiences and outcomes of caregivers who reported frequent and infrequent discrimination. We discuss limitations and implications.

Perceived discrimination and depressive symptoms among US Latinos: the modifying role of educational attainment

OBJECTIVE

Despite growing evidence that discrimination may contribute to poor mental health, few studies have assessed this association among US Latinos. Furthermore, the interaction between discrimination and educational attainment in shaping Latino mental health is virtually unexplored. This study aims to examine the association between perceived discrimination and depressive symptoms and the modifying role of education among a population of Mexican-origin adults.

DESIGN

We utilized population-based data from 629 Mexican-origin adults (mean age = 52.8 years) participating the Niños Lifestyle and Diabetes Study (2013-2014). Perceived discrimination was defined as responding 'sometimes' or 'often' to at least one item on the 9-item Everyday Discrimination Scale. High depressive symptoms were defined as scoring ≥10 on the CESD-10. We used log-binomial and linear-binomial models to estimate prevalence ratios (PR) and prevalence differences (PD), respectively, of high depressive symptoms for levels of perceived discrimination. Final models were adjusted for age, sex, education, cultural orientation, and nativity. General estimating equations were employed to account for within-family clustering.

RESULTS

Prevalence of perceived discrimination and high depressive symptoms were 49.5% and 29.2%, respectively. Participants experiencing discrimination had higher depressive symptom prevalence than those never or rarely experiencing discrimination [PR = 1.94, 95% confidence interval (CI): 1.46-2.58; PD = 0.19, 95% CI: 0.12-0.27]. The strength of this association varied by education level. The association between discrimination and depressive symptoms was stronger among those with >12 years of education (PR = 2.69; PD = 0.24) compared to those with ≤12 years of education (PR = 1.36; PD = 0.09).

CONCLUSION

US Latinos suffer a high burden of depressive symptoms, and discrimination may be an important driver of this burden. Our results suggest that effortful coping strategies, such as achieving high education despite high perceived discrimination, may magnify discrimination's adverse effect on Latino mental health.

Racism and Health: Evidence and Needed Research

In recent decades, there has been remarkable growth in scientific research examining the multiple ways in which racism can adversely affect health. This interest has been driven in part by the striking persistence of racial/ethnic inequities in health and the empirical evidence that indicates that socioeconomic factors alone do not account for racial/ethnic inequities in health. Racism is considered a fundamental cause of adverse health outcomes for racial/ethnic minorities and racial/ethnic inequities in health. This article provides an overview of the evidence linking the primary domains of racism-structural racism, cultural racism, and individual-level discrimination-to mental and physical health outcomes. For each mechanism, we describe key findings and identify priorities for future research. We also discuss evidence for interventions to reduce racism and describe research needed to advance knowledge in this area.

Religiosity and health: A global comparative study

The objective of this paper is to understand global connections between indicators of religiosity and health and how these differ cross-nationally. Data are from World Values Surveys (93 countries, N=121,770). Health is based on a self-assessed question about overall health. First, country-specific regressions are examined to determine the association separately in each country. Next, country-level variables and cross-level interactions are added to multilevel models to assess whether and how context affects health and religiosity slopes. Results indicate enormous variation in associations between religiosity and health across countries and religiosity indicators. Significant positive associations between all religiosity measures and health exist in only three countries (Georgia, South Africa, and USA); negative associations in only two (Slovenia and Tunisia). Macro-level variables explain some of this divergence. Greater participation in religious activity relates to better health in countries characterized as being religiously diverse. The importance in god and pondering life's meaning is more likely associated with better health in countries with low levels of the Human Development Index. Pondering life's meaning more likely associates with better health in countries that place more stringent restrictions on religious practice. Religiosity is less likely to be related to good health in communist and former communist countries of Asia and Eastern Europe. In conclusion, the association between religiosity and health is complex, being partly shaped by geopolitical and macro psychosocial contexts.

Using Values Affirmation to Reduce the Effects of Stereotype Threat on Hypertension Disparities: Protocol for the Multicenter Randomized Hypertension and Values (HYVALUE) Trial

Background

Medication nonadherence is a significant, modifiable contributor to uncontrolled hypertension. Stereotype threat may contribute to racial disparities in adherence by hindering a patient’s ability to actively engage during a clinical encounter, resulting in reduced activation to adhere to prescribed therapies.

Objective

The Hypertension and Values (HYVALUE) trial aims to examine whether a values-affirmation intervention improves medication adherence (primary outcome) by targeting racial stereotype threat.

Methods

The HYVALUE trial is a patient-level, blinded randomized controlled trial comparing a brief values-affirmation writing exercise with a control writing exercise among black and white patients with uncontrolled hypertension. We are recruiting patients from 3 large health systems in the United States. The primary outcome is patients’ adherence to antihypertensive medications, with secondary outcomes of systolic and diastolic blood pressure over time, time for which blood pressure is under control, and treatment intensification. We are comparing the effects of the intervention among blacks and whites, exploring possible moderators (ie, patients’ prior experiences of discrimination and clinician racial bias) and mediators (ie, patient activation) of intervention effects on outcomes.

Results

This study was funded by the National Heart, Lung, and Blood Institute. Enrollment and follow-up are ongoing and data analysis is expected to begin in late 2020. Planned enrollment is 1130 patients. On the basis of evidence supporting the effectiveness of values affirmation in educational settings and our pilot work demonstrating improved patient-clinician communication, we hypothesize that values affirmation disrupts the negative effects of stereotype threat on the clinical interaction and can reduce racial disparities in medication adherence and subsequent health outcomes.

Conclusions

The HYVALUE study moves beyond documentation of race-based health disparities toward testing an intervention. We focus on a medical condition—hypertension, which is arguably the greatest contributor to mortality disparities for black patients. If successful, this study will be the first to provide evidence for a low-resource intervention that has the potential to substantially reduce health care disparities across a wide range of health care conditions and populations.

Coding the Everyday Discrimination Scale: implications for exposure assessment and associations with hypertension and depression among a cross section of mid-life African American women

BACKGROUND

Studies suggest that racial discrimination impacts health via biological dysregulation due to continual adaptation to chronic psychosocial stress. Therefore, quantifying chronicity is critical for operationalising the relevant aetiological exposure and hence maximising internal validity. Using one of the most common discrimination scales in the epidemiological literature, we develop a novel approach for more accurately assessing chronicity and compare it with conventional approaches to determine whether coding influences differential exposure classification and associations with hypertension and depression among African American women.

METHODS

Data are from a socioeconomically diverse cross section of 208 mid-life African American women in Northern California (data collection: 2012-2013). Racial discrimination was assessed using the Everyday Discrimination Scale (α=0.95), and was coded using two conventional approaches: (1) situation-based coding: number of different situations ever experienced; (2) frequency-based coding: sum of Likert scale responses ranging from 'never' to 'almost everyday'; and (3) a new chronicity-based coding approach: sum of responses, weighted to capture annual chronicity (eg, 'a few times a month'=3×12=36×/year). Outcomes are hypertension and depressive symptomatology (10-item Center for Epidemiologic Studies-Depression Scale).

FINDINGS

Exposure classification differed by coding approach, by up to 41%. There was a positive association between racial discrimination and hypertension prevalence for chronicity coding only (prevalence ratio=1.61, 95% CI 1.03 to 2.49). For depressive symptoms, a dose-response relationship of similar magnitude was observed for all three coding approaches.

CONCLUSION

Scale coding is an important methodological consideration for valid exposure assessment in epidemiological research. Coding can impact exposure classification and associations with important indicators of African American women's mental and physical health.

Effects of Neighborhood Discrimination Towards Mainland Immigrants on Mental Health in Hong Kong

Using data from a representative sample of Chinese adults who were surveyed in the Hong Kong Panel Study of Social Dynamics (HKPSSD), we estimate the effects of neighborhood discrimination towards immigrants from Mainland China on the mental health of Chinese residents in Hong Kong. Contrary to our expectations, discrimination towards immigrants from Mainland China measured at the neighborhood level is not associated with the poor mental health of post-1997 immigrants; instead, a higher level of immigrant discrimination is associated with a lower level of psychological distress for both post-1997 Mainland immigrants and other Chinese residents in Hong Kong. A functional family also appears to be a consistent predictor of better mental health for both groups. Our findings, therefore, suggest that immigrant discrimination can signify a prejudice that leads to social distance or avoidance and that the post-1997 Mainland immigrants do not have extensive contact with other local residents in Hong Kong. Although local residents’ discriminatory attitudes may not result in aggressive behaviors that have a negative impact on newcomers’ mental health, the social distance between the immigrants and the local residents is still an issue that requires further research and practical attention.

Xenophobia as a determinant of health: an integrative review

Though xenophobia has become increasingly relevant in today's political climate, little is known about the impact of xenophobia on health. While some studies have shown that xenophobia, in local contexts, may contribute to worse mental health outcomes, none have attempted to review the published literature to integrate these findings. This integrative scoping review examines the strength of these publications, then synthesizes their findings to provide a global perspective on xenophobia. The results show that it is not merely a political threat, but also has real, negative impact on the health of individuals and their communities. Given the multiple negative effects on individual and community health, xenophobia warrants more attention from both a public health and political perspective. Policies that promote cultural integration and understanding are essential to improving community health.

Explaining the Relationship Between Minority Group Status and Health Disparities: A Review of Selected Concepts

Purpose: There is growing concern that value-based payment for health care may disadvantage health care organizations that serve populations with social risk. In the broader investigation of social risk factors, including income, education, neighborhood deprivation, and other risks, the focus on race and ethnicity as a risk factor for disparities in health and health care has diminished. Understanding the independent contribution of minority group status is critical to this discussion. This narrative review discusses four concepts-minority stress, resilience, epigenetics, and life course-that may help explain the contribution of minority group status and its association with health disparities. Methods: We briefly describe each concept and the supporting evidence. Results: Our results indicate that all four concepts have potential relevance for understanding and addressing health disparities. The life course perspective emphasizes the importance of understanding explanatory mechanisms and factors that contribute to health-including biological, physical, and social factors-over a person's life span. Both minority stress and resilience may influence health in either a negative or positive manner that potentially underlies health changes. Exposure to these factors and others may interact with and modify epigenetic regulation-biological processes that impact how our genes are expressed. This may increase the risk of disease and negative health outcomes, particularly among groups that may be at disproportionate risk because of social circumstances and environmental exposure over the life course. Conclusion: Despite these concepts' relevance, more research is needed to assess how they may explain the relationship between minority status and disparities in health. Such evidence is needed to focus interventions and to inform the design of delivery and payment models that can spur actions to reduce disparities.

A Mixed-Methods Study to Examine the Role of Psychosocial Stress and Air Pollution on Hypertension in Mexican-Origin Hispanics

PURPOSE

Independent and combined effects of air pollution and psychosocial stressors on hypertension, a risk factor for cardiovascular disease, among Hispanics are not well studied.

METHODS

We administered a pilot-tested questionnaire on individual- and neighborhood-level psychosocial stressors, developed with community input, to nearly 2500 individuals from the MD Anderson Cancer Center cohort of Mexican-Americans. We used data from local air quality monitors to estimate individual exposures to ozone (O3) and fine particulate matter (PM2.5) for the 12-month period preceding enrollment using inverse distance interpolation. We applied logistic regression models to examine relationships between exposures to psychosocial stressors and air pollution with prevalent hypertension and used stratified analyses to examine the interacting effects of these two exposures on hypertension. RESULTS: There was a positive association between prevalent hypertension and a high frequency of feeling anxious or depressed (prevalence odds ratio (POR) = 1.36, 95% CI [1.06-1.75]) and experiencing aches and pains (POR = 1.29, 95% CI [1.01-1.64]). The odds of having hypertension were also elevated among those worrying about their own health (POR = 1.65, 95% CI [1.30-2.06]) or about not having enough money (POR = 1.27, 95% CI [1.01-1.6]). We observed an inverse association between O3 and hypertension. There was no interaction between psychosocial stressors and O3 on hypertension.

CONCLUSION

Our findings add to the evidence of a positive association between individual and family stressors on hypertension among Hispanics and other racial/ethnic groups. Contrary to previous studies reporting positive associations, our results suggest that long-term exposure to O3 may be inversely related to prevalent hypertension.

On the prevalence of racial discrimination in the United States

Boutwell, Nedelec, Winegard, Shackelford, Beaver, Vaughn, Barnes, & Wright (2017) published an article in this journal that interprets data from the Add Health dataset as showing that only one-quarter of individuals in the United States experience discrimination. In Study 1, we attempted to replicate Boutwell et al.'s findings using a more direct measure of discrimination. Using data from the Pew Research Center, we examined a large sample of American respondents (N = 3,716) and explored the prevalence of discrimination experiences among various racial groups. Our findings stand in contrast to Boutwell et al.'s estimates, revealing that between 50% and 75% of Black, Hispanic, and Asian respondents (depending on the group and analytic approach) reported discriminatory treatment. In Study 2, we explored whether question framing affected how participants responded to Boutwell's question about experiencing less respect and courtesy. Regardless of question framing, non-White participants reported more experiences than White participants. Further, there was an interaction of participant race and question framing such that when participants were asked about experiences of less respect or courtesy broadly, there were no differences between non-White participants and White participants, but when they were asked about experiences that were specifically race-based, non-White participants reported more experiences than White participants. The current research provides a counterweight to the claim that discrimination is not a prevalent feature of the lives of minority groups and the serious implications this claim poses for research and public policy.

An Examination of the Relationship between Discrimination, Depression, and Hypertension in Native Hawaiians

Native Hawaiians bear a disproportionate burden of hypertension. Discrimination and depression are potential hypertension risk factors. Although the relationship between discrimination and depression is well established, how these factors affect hypertension risk in indigenous populations remains unknown. We examined the relationship between discrimination, depression, and hypertension in adult Native Hawaiians. We hypothesized that greater frequency of perceived discrimination and greater frequency of depressive symptoms would independently increase the likelihood of having hypertension. Surveys were mailed to 540 adult Native Hawaiians residing on five Hawaiian Homesteads. The surveys measured: hypertension status, sociodemographic factors (age, gender, income, employment status), body mass index (BMI), physical activity frequency, smoking, Hawaiian cultural affiliation, American cultural affiliation, perceived discrimination, and depressive symptoms. Respondents (n=171) were mostly female (71%), a mean age of 57yrs, and 54% reported having hypertension. The logistic regression model included perceived discrimination, depression, BMI, frequency of vigorous physical activity, and Hawaiian cultural affiliation, and sociodemographic variables. The model showed that Hawaiian cultural affiliation and discrimination were significantly related to hypertension status. Depression was not related to hypertension status. Interaction analysis found that for individuals with lower Hawaiian cultural affiliation, frequent perceived discrimination was significantly associated with lower odds of having hypertension. The negative association between perceived discrimination and hypertension status was opposite from hypothesized. However, the interaction suggests this relationship holds only for less culturally affiliated individuals. These results underscore the varied nature of hypertension determinants and may have clinical implications for the treatment of hypertension in Native Hawaiians.

Sexual Orientation and Gender Identity Victimization Among Young Adults in the New York City Metropolitan Area: The P18 Cohort Study

Sexual and gender minority populations are significantly more likely to experience verbal and physical victimization in young adulthood. These analyses examine the types, contexts, and sources of lifetime sexual orientation and gender identity victimization (SGV) in a diverse sample of sexual minority men (SMM) and transgender women as well as the extent to which experiences of SGV vary between subgroups of the population. Cross-sectional data were collected as part of a study of sexual health, mental health, and HIV examined through the lens of syndemic production in young SMM. Measures assessed sociodemographic characteristics as well as the types, sources, and contexts of physical assault and verbal harassment due to actual or perceived gender or sexuality. Verbal harassment was more prevalent in the sample than physical assault (44.5% vs. 11.6%). Schools or sports teams and neighborhoods were the most common contexts for verbal and physical SGV. Strangers were the most frequent perpetrators of SGV, followed by family and peers. Bivariate analyses showed significant differences in SGV based on race, education, perceived familial SES, sexual identity, and borough of residence. In multivariate analyses, race, SES, sexual identity, and borough of residence were significant predictors of verbal SGV. Findings suggest that SGV experiences are not uniform in sexual minority young adults, and thus prevention and care must be targeted. Understanding the multiple identities of sexual minority young adults who experience greater levels of victimization can allow for policy and interventions to best support those at risk.

Exploring Racism and Health: An Intensive Interactive Session for Medical Students

Introduction

Growing recognition of the deleterious effects of racism on health has led to calls for increased education on racism for health care professionals. As part of a larger curriculum on health equity and social justice, we developed a new educational session on racism for first-year medical students consisting of a lecture followed by a case-based small-group discussion.

Methods

Over the academic years of 2016-2017, 2017-2018, and 2018-2019, a total of 536 first-year medical students participated in this mandatory session. The course materials were developed as a collaboration between faculty and students. The lecture was delivered in a large-group format; the small-group case-based discussion consisted of 10-12 students with one upper-level student facilitator.

Results

The majority of respondents for the course evaluation felt that the course had met its stated objectives, and many commented that they had an increased awareness of the role of racism in shaping health. Students felt that the small-group activity was especially powerful for learning about racism.

Discussion

Active student involvement in curriculum development and small-group facilitation was critical for successful buy-in from students. Additional content on bias, stereotyping, and health care disparities will be the focus of faculty development programs and will also be integrated into the clerkships to build on these important topics as students are immersed in clinical care.

Stress, adherence, and blood pressure control: A baseline examination of Black women with hypertension participating in the SisterTalk II intervention

The prevalence of hypertension is highest among Black women, but treatment adherence is reportedly low. Stress unique to the experiences of Black Americans may be associated with low adherence and poor blood pressure control, but few studies have examined the relationships between stress, adherence, and blood pressure control among hypertensive Black women. This study seeks to fill gaps in research by examining the association between stress, adherence, and blood pressure control. The baseline sample (n = 571) of at-risk or hypertensive Black women from the SisterTalk II RCT (Northeastern USA, 2004-2006) to improve adherence to recommendations for hypertension was analyzed. Participants self-reported stress, pharmacological adherence, non-pharmacological adherence (i.e. lifestyle management such as diet and exercise), and demographics. Blood pressure and anthropometrics (BMI and waist circumference) were measured. Statistical analysis included ANOVA, t-tests, linear regression. Tests of mediation examined if adherence mediated the relationship between stress and blood pressure control. This study found that stress was associated with lower age (p < .001) and being a single parent (p < .001). Stress was also associated with higher systolic blood pressure (p = .029), and poor blood pressure control (p = .043). Participants who reported higher stress also reported lower non-pharmacological adherence (p = .042). Non-pharmacological adherence was found to mediate the association between stress and blood pressure control. Hence, results document a relationship between stress with non-pharmacological adherence and blood pressure control among Black American women. More research is necessary to examine the relationship between stress and treatment adherence.

Weight bias among exercise and nutrition professionals: a systematic review

Obesity affects approximately one-third of American adults. Recent evidence suggests that weight bias may be pervasive among both exercise and nutrition professionals working with adults who have obesity. However, the published literature on this topic is limited. This review aimed to (i) systematically review existing literature examining weight bias among exercise and nutrition professionals; (ii) discuss the implications of this evidence for exercise and nutrition professionals and their clients; (iii) address gaps and limitations of this literature; and (iv) identify future research directions. Of the 31 studies that met the criteria for this review, 20 examined weight bias among exercise professionals, of which 17 (85%) found evidence of weight bias among professionals practicing physical therapy (n = 4), physical education (n = 8) and personal/group fitness training (n = 5). Of 11 studies examining weight bias among nutrition professionals, eight (73%) found evidence of weight bias. These findings demonstrate fairly consistent evidence of weight bias among exercise and nutrition professionals. However, the majority of studies were cross-sectional (90%). Given that weight bias may compromise quality of care and potentially reinforce weight gain and associated negative health consequences in patients with obesity, it is imperative for future work to examine the causes and consequences of weight bias within exercise and nutrition professions using more rigorous study designs.

Does the healthy immigrant effect apply to mental health? Examining the effects of immigrant generation and racial and ethnic background among Australian adults

The healthy immigrant effect (HIE) refers to the phenomena in which immigrants show greater health outcomes than the native-born population. However, it is unclear what is the extent to which HIE applies to various outcomes and populations. Much of the work on HIE has revolved around physical health outcomes; mental health, however, has not garnered the same level of attention with regard to HIE. It is also uncertain whether immigrants’ health advantage persists beyond one generation. This study assesses the mental health of the first, second, and third and higher generations (70,517 person-year observations) for individuals from various racial and ethnic backgrounds in Australia using Waves 1−16 of the Household Income and Labour Dynamics in Australia survey. The dependent variable is mental health score and key independent variables include generation and racial and ethnic background. I control for age, educational attainment, labor force status, marital status, remoteness, household income, language, neighborhood disadvantage, citizenship, weight, and gender. Using linear regression with random effects, this study finds that mental health varies by generation; the third and higher generation show the greatest mental health score, followed by the first generation and the second generation, net of controls. Mental health score also varies by racial and ethnic background. Except for English-speaking groups, native-born Australians show a clear advantage over Europeans, North Africans/Middle Easterners, and Asians. Racial and ethnic disparities differ by generation and are strongest among the first generation. My findings extend HIE, which typically emphasize immigrants’ superior health outcomes over the native-born population but do not focus on racial and ethnic disparities among immigrants. My results suggest that immigrant groups vary widely in their mental health outcomes but these lessen over time. Overall, the findings suggest the limited applicability of HIE for a broad range of health outcomes and populations.

•

The third and higher generation have the highest mental health scores, followed by the first and second generations.

•

The first generation's mental health scores are associated with relatively fewer factors relative to the second and third and higher generations.

•

English-speaking groups show the highest mental health followed by native-born Australians.

•

All other minority groups show lower mental health scores.

•

Racial and ethnic disparities in mental health differ by generation.

Interpersonal and institutional ethnic discrimination, and mental health in a random sample of Palestinian minority men smokers in Israel

PURPOSE

We sought to extend research into the health effects of discrimination to a non-Western context. We examined the associations between interpersonal and institutional ethnic discrimination, and anxiety and depression among Palestinian-Arab minority men citizens of Israel.

METHODS

We used data from a nationwide stratified random sample of 964 Arab men in Israel, current or former smokers (age 18-64), who were interviewed as part of a 2012-2013 study on cessation. The questionnaire included an adapted Arabic version of the Experiences of Discrimination scale and a new scale on perceived institutional group discrimination. Logistic regression models estimated the effects of both forms of discrimination on depressive symptoms (Center for Epidemiological Studies Depression Scale) and anxiety (State-Trait Anxiety Inventory), while adjusting for socio-demographic and economic factors.

RESULTS

The prevalence of depressive symptoms was 24.7% and anxiety 45.5%. Approximately 42% of men reported experiencing interpersonal discrimination, and 50.8% reported perceived institutional group discrimination. Controlling for covariates, experiencing interpersonal discrimination was associated with higher odds for depressive symptoms [OR = 2.36, 95% confidence intervals (CI) = 1.69-1.57] and anxiety (OR = 1.92, 95% CI = 1.45-2.55). Perceived institutional group discrimination was associated only with anxiety (OR = 1.76, 95% CI = 1.32-2.35). Introducing both forms of discrimination into the same model slightly attenuated these associations.

CONCLUSIONS

Interpersonal and institutional forms of ethnic discrimination are independently associated with poorer mental health among Arab minority men current and former smokers in Israel. Future research is warranted into both forms of discrimination in the general Arab population in Israel, including women.

Perceived discrimination is associated with the inflammatory response to acute laboratory stress in women at risk for cardiovascular disease

Cardiovascular disease (CVD) is the leading cause of death in the United States and exacts a disproportionate toll on minorities. Growing evidence demonstrates that perceived discrimination is a significant contributing factor to psychological distress, chronic low-grade inflammation, and cardiovascular health. However, little is known regarding the extent to which perceived discrimination contributes to the inflammatory response to acute stress. Therefore, the purpose of this study was to examine the influence of perceived discrimination on the inflammatory response to a laboratory acute stress paradigm in women at risk for CVD. A cross-sectional sample of 99 postmenopausal women (50 African American and 49 non-Hispanic White) (mean age 60.2 years) with at least two risk factors for CVD underwent the Trier Social Stress Test (TSST). Subjects completed the Detroit Area Study Discrimination Scale (DAS-DS) Everyday Discrimination subscale and provided blood and saliva samples prior to the TSST and every 15 min up to 90 min post-TSST to measure a pro-inflammatory cytokine, interleukin-6 (IL-6). Perceived discrimination was significantly associated with the salivary IL-6 response to the TSST (b = 0.49, SE = 0.13, p = <0.001) controlling for age, race, marital status, household income, BMI, statin use, childhood maltreatment, depressive symptoms, and subjective social status. Women who reported higher levels of perceived discrimination had higher levels of salivary IL-6 at baseline and following the TSST as compared to women who reported lower levels of perceived discrimination. Results suggest that higher levels of perceived discrimination, regardless of race and socioeconomic status, may heighten levels of inflammation, prior to and following an acute stress exposure. The circulating Il-6 response was associated with BMI only and did not correlate with salivary IL-6. These data suggest that perceived discrimination may contribute to the salivary-IL-6 acute stress response. However, more research is needed to help clarify the complex relationships among stress and salivary proinflammatory cytokines.

Blood pressure recovery to social stress in parentally bereaved and non-bereaved youths

OBJECTIVE

To examine differences in blood pressure response and recovery in a sample of bereaved and non-bereaved youths during an acute stress task conducted 5 years after time of parental death.

METHODS

One-hundred and ninety-two (n = 192) bereaved and non-bereaved offspring (ages 11-29) participated in an adaptation of the Trier Social Stress Task (TSST) 5-years after the time of parental death. Blood pressure measurements were collected before, during, and after the laboratory stress protocol. Mixed models for repeated measures were used to analyze the effects of bereavement status and course of psychiatric disorder in the 5-year period after parental death in both offspring and caregivers on blood pressure response; linear regression was used to examine these associations with blood pressure recovery.

RESULTS

Although there were no differences across groups in diastolic (DBP) or systolic blood pressure (SBP) response to stress, bereaved offspring demonstrated less SBP recovery to the TSST as compared to non-bereaved offspring. A significant interaction between bereavement status and race, and a marginally significant interaction between bereavement status and sex indicated poor SBP recovery for parentally bereaved racial/ethnic minority offspring as compared to parentally bereaved Caucasian offspring, and for parentally bereaved males compared to parentally bereaved females.

CONCLUSIONS

Parentally bereaved youths demonstrate blood pressure response to social stress tasks similar to that of non-bereaved youths, but parentally bereaved ethnic/racial minority youths and parentally bereaved males evidence a less complete recovery from the effects of stress. The health consequences of poor blood pressure recovery in bereaved youths are discussed.

Relationship of Time-Activity-Adjusted Particle Number Concentration with Blood Pressure

Emerging evidence suggests long-term exposure to ultrafine particulate matter (UFP, aerodynamic diameter < 0.1 µm) is associated with adverse cardiovascular outcomes. We investigated whether annual average UFP exposure was associated with measured systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and hypertension prevalence among 409 adults participating in the cross-sectional Community Assessment of Freeway Exposure and Health (CAFEH) study. We used measurements of particle number concentration (PNC, a proxy for UFP) obtained from mobile monitoring campaigns in three near-highway and three urban background areas in and near Boston, Massachusetts to develop PNC regression models (20-m spatial and hourly temporal resolution). Individual modeled estimates were adjusted for time spent in different micro-environments (time-activity-adjusted PNC, TAA-PNC). Mean TAA-PNC was 22,000 particles/cm³ (sd = 6500). In linear models (logistic for hypertension) adjusted for the minimally sufficient set of covariates indicated by a directed acyclic graph (DAG), we found positive, non-significant associations between natural log-transformed TAA-PNC and SBP (β = 5.23, 95%CI: −0.68, 11.14 mmHg), PP (β = 4.27, 95%CI: −0.79, 9.32 mmHg), and hypertension (OR = 1.81, 95%CI: 0.94, 3.48), but not DBP (β = 0.96, 95%CI: −2.08, 4.00 mmHg). Associations were stronger among non-Hispanic white participants and among diabetics in analyses stratified by race/ethnicity and, separately, by health status.

Perceived discrimination and cardiovascular health disparities: a multisystem review and health neuroscience perspective

There are distinct racial disparities in cardiovascular disease (CVD) risk, with Black individuals at much greater risk than White individuals. Although many factors contribute to these disparities, recent attention has focused on the role of discrimination as a stress-related factor that contributes to racial disparities in CVD. As such, it is important to understand the mechanisms by which discrimination might affect CVD. Recent studies have examined these mechanisms by focusing on neurobiological mediators of CVD risk. Given this increase in studies, a systematic review of perceived discrimination and neurobiological mediators of CVD risk is warranted. Our review uses a multisystem approach to review studies on the relationship between perceived discrimination and (1) cardiovascular responses to stress, (2) hypothalamic-pituitary-adrenocortical axis function, and (3) the immune system, as well as (4) the brain systems thought to regulate these parameters of peripheral physiology. In addition to summarizing existing evidence, our review integrates these findings into a conceptual model describing multidirectional pathways linking perceived discrimination with a CVD risk.
