Discrimination, racial bias, and telomere length in African-American men

Why public health framing matters: An experimental study of the effects of COVID-19 framing on prejudice and xenophobia in the United States

The COVID-19 pandemic has triggered a notable increase in the expression of prejudicial and xenophobic attitudes that threaten the wellbeing of minority groups and contribute to the overall public health toll of the virus. However, while there is evidence documenting the growth in discrimination and xenophobia, little is known about how the COVID-19 outbreak is activating the expression of such negative attitudes. The goal of the current paper therefore was to investigate what aspects of the COVID-19 pandemic may be contributing to this rise in expressions of prejudice and xenophobia. More specifically, this study used an experimental design to assess the effects of using stigmatized language to describe the virus as well as the threat to physical health and economic wellbeing posed by the virus on COVID-19 prejudice. Data were collected from a national sample of 1451 adults residing within the United States. Results from 2 × 2 x 2 between-subjects analyses of covariance demonstrated that emphasizing the connection between China and COVID-19, rather than framing the virus neutrally, increased negative attitudes toward Asian Americans, beliefs that resources should be prioritized for Americans rather than immigrants, and general xenophobia. Emphasizing the severity of the economic impact of the virus also increased beliefs that Asian Americans are a threat to resources and general xenophobia. In contrast, messages which emphasized the serious health risks of COVID-19 did not increase bias toward Asian Americans or xenophobia. Our findings suggest that specific types of public health messaging related to infectious diseases, especially framing the virus in terms of its country of origin or its likely economic impact, may elicit prejudice and xenophobia. Public health campaigns that emphasize the severity of the virus, however, are not likely to trigger the same negative attitudes. Implications for public health responses to health crises are discussed.

Meaning in Life Predicts Decreased Depressive Symptoms and Increased Positive Affect over Time but Does Not Buffer Stress Effects in a National Sample of African-Americans

Few studies have specifically focused on meaning in life in African Americans and many important questions remain, including whether effects of meaning in life are direct or moderated by levels of stress. In a national sample of 909 African Americans, we tested meaning in life as a prospective predictor of changes in depressive symptoms and positive affect over a 2.5-year period. Controlling for demographics and hassles, meaning in life predicted decreased depressive symptoms and increased positive affect across the span of 2.5 years. Moderation effects were not found for hassles, age, or income. Gender moderated the effect of meaning on positive affect such that effects were stronger for women than for men. These results suggest that, for African Americans, meaning in life appears to robustly protect against future depressive symptoms and promote positive affect over time unaffected by amount of stress experienced or most demographic factors.

Development of a SCAR marker linked to fungal pathogenicity of rice blast fungus Magnaporthe Oryzae

PCR-based molecular approaches including RAPD (random amplified polymorphic DNA), ISSR (inter-simple sequence repeat), and SRAP (sequence-related amplified polymorphism) are commonly used to analyze genetic diversity. The aims of this study are to analyze genetic diversity of M. oryzae isolates using PCR-based molecular approaches such as RAPD, ISSR, and SRAP and to develop SCAR marker linked to the pathogenicity of rice blast fungus. Twenty Magnaporthe oryzae isolates were collected mainly from the south of Vietnam and assessed for genetic variation by RAPD, ISSR, and SRAP methods. The comparison of those methods was conducted based on the number of polymorphic bands, percentage of polymorphism, PIC values, and phylogenetic analysis. Then, sequenced characterized amplified region (SCAR) markers were developed based on specific bands linked to fungal pathogenicity of rice blast fungus, M. oryzae. The results indicated that SRAP markers yielded the greatest number of polymorphic bands (174) and occupied 51.7% with polymorphism information content (PIC) value of 0.66. Additionally, the SRAP approach showed stability and high productivity compared with RAPD and ISSR. The SCAR marker developed from the SRAP method identified the presence of the avirulence AVR-pita1 gene involving fungal pathogenicity that can break down blast resistance in rice cultivars. The consistency of SCAR marker obtained in this study showed its efficiency in rapid in-field detection of fungal pathogenicity. SCAR marker developed from SRAP technique provides a useful tool for improving the efficiency of blast disease management in rice fields.

A systematic review on the effects of social discrimination on telomere length

Discrimination is unfair treatment against a certain group based on race, age, gender, sexual orientation, or other social identities. Discrimination is pervasive in society, elevates psychosocial stress, and is associated with negative mental and physical health outcomes. However, more research is needed to understand the biological mechanisms underlying discrimination-related health disparities. Telomere science may contribute to elucidate some of these aspects. Telomeres are protein-DNA complexes that shorten after cell division and are valuable markers of cellular aging. Short telomeres have been associated with the onset of age-related diseases. Evidence shows that chronic psychological stress may accelerate telomere shortening. Since discrimination can lead to psychological strain with cumulative impact on general health, we hypothesized that groups that report more discrimination show reduced telomere length (TL) as a consequence of psychosocial stress elevation. Through a systematic review of the literature we found 12 articles that met our criteria. Eligible studies measured racial, gender, unfair policing, and multiple forms of discrimination in association with TL. Our review showed mixed results, suggesting that there is weak evidence of a main association between discrimination and TL. However, discrimination may interact with several variables (such as depressive symptoms, acculturation, higher socioeconomic status, internalization of negative racial bias, and not discussing discrimination experiences with others) and contribute to shorten telomeres. Discrimination is a complex social construct composed of a vast sum of experiences, impressions, and contexts that in combination with other sources of stress may have an impact on TL. Telomeres may be a plausible pathway to investigate health discrepancies in discriminated groups in society, but more evidence is needed to investigate the potential harm of discrimination on cells.

Disparities in patient-centered communication for Black and Latino men in the U.S.: Cross-sectional results from the 2010 health and retirement study

BACKGROUND

A lack of patient-centered communication (PCC) with health providers plays an important role in perpetuating disparities in health care outcomes and experiences for minority men. This study aimed to identify factors associated with any racial differences in the experience of PCC among Black and Latino men in a nationally representative sample.

METHODS

We employed a cross-sectional analysis of four indicators of PCC representative of interactions with doctors and nurses from (N = 3082) non-Latino White, Latino, and Black males from the 2010 Health and Retirement Study (HRS) Core and the linked HRS Health Care Mail in Survey (HCMS). Men's mean age was 66.76 years. The primary independent variable was Race/Ethnicity (i.e. Black and Hispanic/Latino compared to white males) and covariates included age, education, marital status, insurance status, place of care, and self-rated health.

RESULTS

Bivariate manova analyses revealed racial differences across each of the four facets of PCC experience such that non-Hispanic white men reported PC experiences most frequently followed by black then Hispanic/Latino men. Multivariate linear regressions predictive of PCC by race/ethnicity revealed that for Black men, fewer PCC experiences were predicted by discriminatory experiences, reporting fewer chronic conditions and a lack of insurance coverage. For Hispanic/Latino men, access to a provider proved key where not having a place of usual care solely predicted lower PCC frequency.

IMPLICATIONS

Researchers and health practitioners should continue to explore the impact of inadequate health care coverage, time-limited medical visits and implicit racial bias on medical encounters for underrepresented patients, and to advocate for accessible, inclusive and responsive communication between minority male patients and their health providers.

Mechanisms of Racial Health Disparities: Relationships between Coping and Psychological and Physiological Stress Responses

Objective

Psychological distress and physiological dysregulation represent two stress response pathways linked to poor health and are implicated in racial disparities in aging-related health outcomes among US men. Less is known about how coping relates to these stress responses. The purpose of this exploratory study was to examine whether midlife and older men's coping strategies and behaviors accounted, in part, for Black-White disparities in men's psychological and physiological stress responses.

Methods

We examined racial differences in 12 coping strategies (COPE Inventory subscales, religious/spiritual coping, and behaviors such as stress eating and substance use) and their relationships with psychological distress (Negative Affect scale) and physiological dysregulation (blunted diurnal cortisol slopes) using regression models and cross-sectional data from 696 Black and White male participants aged 35-85 years in the National Survey of Midlife Development in the United States (MIDUS) II, 2004-2006.

Results

Black men exhibited more psychological distress and physiological dysregulation than White men. Black and White men reported comparable use of most coping strategies, none of which demonstrated similar relationships with both stress responses. Coping strategies explained variations in psychological distress consistent with conventional protective-harmful categorizations. Coping accounted for racial disparities in men's psychological distress, as Black men reported using harmful strategies more often and were more susceptible to their negative effects. Neither differential use of coping strategies nor differing relationships accounted for racial disparities in physiological dysregulation.

Conclusions

Findings revealed complex relationships between coping and psychological and physiological stress responses and suggest the importance of differing approaches to reducing associated racial health disparities among men.

Discrimination as a social determinant of stress and health among New York City taxi drivers

Discrimination is associated with poorer mental and physical health outcomes. Taxi drivers have a higher risk of exposure to discrimination and higher rates of chronic conditions. A cross-sectional needs assessment was conducted with a multilingual group of 535 male taxi drivers in New York City. Drivers reporting higher discrimination were more likely to have higher perceived stress and were more likely to have anxiety/depression and chronic pain, adjusting for confounders. Workplace-based interventions designed to help drivers cope with discrimination, stress, and chronic health conditions, interventions to educate the taxi-riding public, and greater attention to these issues from administrative agencies are warranted.

Neurobiological Markers of Resilience to Early-Life Adversity During Adolescence

Early-life adversity (ELA) exposure (e.g., trauma, abuse, neglect, or institutional care) is a precursor to poor physical and mental health outcomes and is implicated in 30% of adult mental illness. In recent decades, ELA research has increasingly focused on characterizing factors that confer resilience to ELA and on identifying opportunities for intervention. In this review, we describe recent behavioral and neurobiological resilience work that suggests that adolescence (a period marked by heightened plasticity, development of key neurobiological circuitry, and sensitivity to the social environment) may be a particularly opportune moment for ELA intervention. We review intrapersonal factors associated with resilience that become increasingly important during adolescence (specifically, reward processing, affective learning, and self-regulation) and describe the contextual factors (family, peers, and broader social environment) that modulate them. In addition, we describe how the onset of puberty interacts with each of these factors, and we explore recent findings that point to possible "pubertal recalibration" of ELA exposure as an opportunity for intervention. We conclude by describing considerations and future directions for resilience research in adolescents, with a focus on understanding developmental trajectories using dimensional and holistic models of resilience.

An Online Behavioral Health Intervention Promoting Mental Health, Manhood, and Social Support for Young Black Men: The YBMen Project

Conventional definitions of mental health, manhood, and social support create barriers to accessing behavioral health care for Black men ages 18 to 30. Targeted behavioral health interventions sensitive to culture, social norms, and gender that circumvent these barriers are desperately needed to improve access and integrated care for this group. This article reports mixed methods findings from the 2017 iteration of the Young Black Men, Masculinities, and Mental Health (YBMen) project, a social media-based, psychoeducational program that promotes mental health, progressive definitions of manhood, and sustainable social support for Black men. Young Black men (n = 350) across two universities in the Midwest completed baseline surveys on their mental health, definitions of manhood, and social support. Forty of the men participated in the YBMen intervention and at postintervention reported experiencing fewer depressive symptoms on the Patient Health Questionnaire (PHQ-9, Z = -2.05, p < .01) and the Gotland Male Depression Scale (GMDS; Z = -1.76, p < .05). There were also changes on the Conformity to Masculine Norms Inventory (CMNI) for Self-Reliance (Z = -0.34, p = .26) and Heterosexual Self-Presentation (Z = -0.18, p = .59), though these changes were not statistically significant. A qualitative review of postintervention interviews revealed participants' appreciation of the YBMen project and its influence on their mental health, manhood, and social support. Programmatic efforts that support the behavioral health, positive development, and social relationships of Black men translate into positive families, communities, and experiences as they live, learn, love, and work over the life course.

Discrimination and sexual risk among Caribbean Latinx young adults

Objectives: Discrimination, such as being treated unfairly due to race, contributes to stress. Individuals may cope with this by engaging in risky behaviors. Consistent with this premise, prior studies found that discrimination is associated with substance use. Research has also shown that sex while 'high' on alcohol and drugs is associated with increased risk for HIV and other STIs. The present study examines the relationship between discrimination and sexual risk. We investigate whether discrimination is associated with sex while high on alcohol and drugs. Design: Analyses focus on a sample of 356 Caribbean Diasporic young adults, primarily Caribbean Latinx, aged 18 to 25 who participated in the Drug Use and HIV Risk among Youth Survey carried out from 1997 to 2000 in Brooklyn, New York. Logistic regression examined the association between self-reported discrimination and sex while high. Results: More than half (52.3%) of respondents reported moderate discrimination. Sex while high was also reported: 35.7% for alcohol, 43.3% for marijuana, and 32.6% for heroin/cocaine. Discrimination was associated with increased risk of sex while high on (1) marijuana and (2) heroin/cocaine, but was not with alcohol. Conclusions: Discrimination may be a risk factor for engaging in sex while high on drugs, which may put individuals at risk for HIV as well as other STIs. Future research should explore relationships between discrimination and sex while high on alcohol and drugs among various racial/ethnic groups and Diasporas, while also assessing how this relationship may contribute to HIV incidence.

Advances in Understanding the Causes and Consequences of Health Disparities in Aging Minorities

PURPOSE OF REVIEW

The purpose was to discuss appropriate methods for advancing our understanding of health disparities or minority aging including life-course perspectives, biological measures, pain measurement, and generational approaches.

RECENT FINDINGS

Life course perspectives provide an orientation for studying older minorities that concomitantly captures exposures and stressors that may lead to earlier onset of disease and premature mortality. The use of biological markers to study health disparities in older minorities is necessary in order to identify pathways between psychosocial factors and health outcomes. Work focusing on pain disparities should include explorations of relationships between psychosocial factors, and subjective and objective measures of pain. Studying families can provide insight into genetic associations and coping styles in older minorities.

SUMMARY

Methodological approaches that take life course, biology, and social factors into account may help identify causal pathways between social determinants of health and health outcomes among older minorities. Once these causal pathways have been identified, more strategies and interventions that strive toward health equity across older adults of all race/ethnic groups can be developed.

Association between racial discrimination and health-related quality of life and the impact of social relationships

PURPOSE

Interpersonal racial discrimination is associated with poor health. Social relationships may moderate the impact of discrimination and represent modifiable behaviors that can be targeted by public health interventions. We described citywide associations between self-reported racial discrimination and health-related quality of life among the overall New York City (NYC) adult residential population and by four main race/ethnicity groups and explored whether social relationships moderated health effects of discrimination.

METHODS

We analyzed cross-sectional survey data from 2335 adults weighted to be representative of the NYC population. We measured exposures to lifetime interpersonal racial discrimination in nine domains using a modified version of the Experiences of Discrimination scale. We performed unadjusted and adjusted regression analyses on four self-rated health-related quality of life outcomes including general health, physical health, mental health, and limitations from physical or mental health.

RESULTS

Overall, 47% [95% CI 44.5, 50.3] of respondents reported having experienced racial discrimination in at least one domain. In the overall population, significant associations with racial discrimination were noted in adjusted models for poor physical health, poor mental health, and limitations by poor physical and mental health. Among those exposed to racial discrimination, the risk of experiencing poor mental health was lower among those who had contact with family or friends outside their household at least once a week, compared with those who had less frequent social contact.

CONCLUSION

This study provides evidence that social relationships may moderate the impact of racial discrimination on mental health and should be integrated into health promotion efforts.

Psychosocial Stressors and Telomere Length: A Current Review of the Science

A growing literature suggests that exposure to adverse social conditions may accelerate biological aging, offering one mechanism through which adversity may increase risk for age-related disease. As one of the most extensively studied biological markers of aging, telomere length (TL) provides a valuable tool to understand potential influences of social adversity on the aging process. Indeed, a sizeable literature now links a wide range of stressors to TL across the life span. The aim of this article is to review and evaluate this extant literature with a focus on studies that investigate psychosocial stress exposures and experiences in early life and adulthood. We conclude by outlining potential biological and behavioral mechanisms through which psychosocial stress may influence TL, and we discuss directions for future research in this area.

A Meta-Analysis of the Relationship Between Internalized Racial Oppression and Health-Related Outcomes

Internalized racism represents a critical component of the system of racial oppression wherein People of Color adopt the negative beliefs about their race held by members of the White majority group. In this meta-analysis, the authors reviewed 29 studies (32 effect sizes) on the relationships between internalized racism and negative physical and mental health outcomes published between 1999 and 2015 and tested for literature-driven moderator effects using subgroup analyses. Results suggested that the direct overall relation between internalized racism and health was strongest for negative mental health outcomes ( r = .26), followed by negative physical health outcomes ( r = .11). Significant moderator effects were found for scale of measurement, country of sample (United States vs. international), and sampling method. Moderator effects of gender, publication type, year, and sample setting were not statistically significant. These findings are discussed and their implications for practice, advocacy, education/training, and research are described.

Racial discrimination and telomere shortening among African Americans: The Coronary Artery Risk Development in Young Adults (CARDIA) Study

OBJECTIVE

Telomeres are protective sequences of DNA capping the ends of chromosomes that shorten over time. Leukocyte telomere length (LTL) is posited to reflect the replicative history of cells and general systemic aging of the organism. Chronic stress exposure leads to accelerated LTL shortening, which has been linked to increased susceptibility to and faster progression of aging-related diseases. This study examined longitudinal associations between LTL and experiences of racial discrimination, a qualitatively unique source of minority psychosocial stress, among African Americans.

METHOD

Data are from 391 African Americans in the Coronary Artery Risk Development in Young Adults (CARDIA) Telomere Ancillary Study. We examined the number of domains in which racial discrimination was experienced in relation to LTL collected in Years 15 and 25 (Y15: 2000/2001; Y25: 2010/2011). Multivariable linear regression examined if racial discrimination was associated with LTL. Latent change score analysis (LCS) examined changes in racial discrimination and LTL in relation to one another.

RESULTS

Controlling for racial discrimination at Y15, multivariable linear regression analyses indicated that racial discrimination at Y25 was significantly associated with LTL at Y25. This relationship remained robust after adjusting for LTL at Y15 (b = -.019, p = .015). Consistent with this finding, LCS revealed that increases in experiences of racial discrimination were associated with faster 10-year LTL shortening (b = -.019, p = .015).

CONCLUSIONS

This study adds to evidence that racial discrimination contributes to accelerated physiologic weathering and health declines among African Americans through its impact on biological systems, including via its effects on telomere attrition.

New Evidence of Skin Color Bias and Health Outcomes Using Sibling Difference Models: A Research Note

In this research note, we use data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to determine whether darker skin tone predicts hypertension among siblings using a family fixed-effects analytic strategy. We find that even after we account for common family background and home environment, body mass index, age, sex, and outdoor activity, darker skin color significantly predicts hypertension incidence among siblings. In a supplementary analysis using newly released genetic data from Add Health, we find no evidence that our results are biased by genetic pleiotropy, whereby differences in alleles among siblings relate to coloration and directly to cardiovascular health simultaneously. These results add to the extant evidence on color biases that are distinct from those based on race alone and that will likely only heighten in importance in an increasingly multiracial environment as categorization becomes more complex.

Discrimination, social support, and telomere length: the Multi-Ethnic Study of Atherosclerosis (MESA)

PURPOSE

We sought to assess the association of reports of discrimination with leukocyte telomere length (LTL) and effect measure modification by social support.

METHODS

This study used data from the Multi-Ethnic Study of Atherosclerosis Stress Ancillary Study (n = 1153). Discrimination was measured using the everyday discrimination and the major experiences of discrimination scales. LTL was defined as the ratio of telomeric DNA to single-copy control gene (mean = 0.916, SD = 0.205). Linear regression models were used to examine the relationship between discrimination and LTL.

RESULTS

We found no association between either measure of discrimination and LTL, but there was evidence of effect modification by social support (P (χ2) = 0.001) for everyday discrimination only. Among those with low social support, reporting moderate and high everyday discrimination was associated with a 0.35 (95% CI: -0.54 to -0.16) and a 0.17 (95% CI: -0.34 to -0.01) shorter telomere length, respectively, compared to reporting no discrimination, after adjusting for demographic factors, health behaviors, and health conditions. There were no associations between discrimination and LTL among those reporting moderate or high social support.

CONCLUSIONS

These findings underscore the importance of continued investigation of the potential health consequences of chronic unfair treatment in the absence of supportive resources.

"That Guy is Gay and Black. That's a Red Flag." How HIV Stigma and Racism Affect Perception of Risk Among Young Black Men Who Have Sex with Men

Young Black men who have sex with men's (YBMSM) attitudes and personal beliefs about themselves and their risk for HIV can be modified as a result of experiences with racism and HIV stigma. In-depth qualitative interviews were conducted with 25 HIV-negative YBMSM, aged 18-24, in North Carolina and Maryland. Data were thematically analyzed to capture participants' experiences and thoughts related to stigmatizing experiences and their perception of risk for HIV. Participants reported experiencing HIV stigmatizing and blatant racist commentary related to their identities as YBMSM. Participants described diverse strategies to distance themselves from these negative stereotypes and decrease their sexual risk for HIV. The findings highlight that HIV stigma and racial stereotypes are one of the many types of discrimination that YBMSM experience within the Black and gay communities and in society; leading to psychological distress and an altered perception of self and sexual risk.

Shortened telomere length is associated with unfair treatment attributed to race in African Americans living in Tallahassee, Florida

OBJECTIVES

Experiences of interpersonal discrimination are pervasive stressors in the lives of African Americans. Increased discrimination stress may cause premature aging. Telomere length (TL) is a plastic genetic trait that is an emerging indicator of cellular health and aging. Short TL is a risk factor for the earlier onset of disease. TL shortens with age, a process that may be accelerated by psychosocial stress. Our study explores the relationship between TL and experiences of discrimination in the form of self-reported unfair treatment (UT).

METHODS

Using a qPCR-based method, we measured TL in DNA from saliva samples provided by 135 African American adults from Tallahassee, FL. We developed discrimination measures using a modified survey that explores nine social domains of self-reported unfair treatment experienced both directly and indirectly. We used multiple regression to examine associations between UT and TL.

RESULTS

We found that racial discrimination in the form of self-reported unfair treatment attributed to race (UT-Race-Self) is inversely associated with TL.

CONCLUSIONS

The significant association between increased UT-Race-Self and shorter telomeres supports the hypothesis that psychosocial stress stemming from racial discrimination may affect TL. The potential impact of discrimination on TL may contribute to premature biological aging and racial health inequalities seen in African Americans.

The Intergenerational Transmission of Discrimination: Children's Experiences of Unfair Treatment and Their Mothers' Health at Midlife

A growing body of research suggests that maternal exposure to discrimination helps to explain racial disparities in children's health. However, no study has considered if the intergenerational health effects of unfair treatment operate in the opposite direction-from child to mother. To this end, we use data from mother-child pairs in the National Longitudinal Survey of Youth 1979 to determine whether adolescent and young adult children's experiences of discrimination influence their mother's health across midlife. We find that children who report more frequent instances of discrimination have mothers whose self-rated health declines more rapidly between ages 40 and 50 years. Furthermore, racial disparities in exposure to discrimination among children explains almost 10% of the black-white gap but little of the Hispanic-white gap in self-rated health among these mothers. We conclude that the negative health impacts of discrimination are likely to operate in a bidirectional fashion across key family relationships.

The relationship between neighborhood socioeconomic deprivation and telomere length: The 1999-2002 National Health and Nutrition Examination Survey

Socioeconomically disadvantaged neighborhoods have been associated with poor health outcomes. Little is known about the biological mechanism by which deprived neighborhood conditions exert negative influences on health. Data from the 1999–2002 National Health and Nutrition Examination Surveys (NHANES) were used to assess the relationship between neighborhood deprivation index (NDI) and log-transformed leukocyte telomere length (LTL) via multilevel modeling to control for census tract level clustering. Models were constructed using tertiles of NDI (ref = low NDI). NDI was calculated using census tract level socioeconomic indicators from the 2000 U.S. Census. The sample (n = 5,106 adults) was 49.8% female and consisted of 82.9% non-Hispanic whites, 9.4% non-Hispanic blacks, and 7.6% Mexican Americans. Mean age was 45.8 years. Residents of neighborhoods with high NDI were younger, non-white, had lower educational attainment, and had a lower poverty to income ratio (all p < 0.0001). Neighborhood deprivation was inversely associated with LTL among individuals living in neighborhoods with medium NDI (β = −0.043, SE = 0.012, p = 0.0005) and high NDI (β = −0.039, SE = 0.013, p = 0.003). Among men, both medium (β = −0.042, SE = 0.015, p = 0.006) and high (β = −0.047, SE = 0.015, p = 0.001) NDI were associated with shorter LTL. Among women, only medium NDI (β = −0.020, SE = 0.016, p = 0.009) was associated with shorter LTL. After controlling for individual characteristics, including individual-level socioeconomic status, increasing neighborhood socioeconomic deprivation is associated with shorter LTL among a nationally representative sample of US adults. This suggests that telomere shortening may be a mechanism through which neighborhood deprivation results in poor health outcomes.

•

Neighborhood deprivation is inversely related to telomere length.

•

This persists after adjusting for behavior and individual socioeconomic status.

•

Telomere shortening in high deprivation represented 7.5 years of accelerated aging.

•

Telomere shortening may be a mechanism linking neighborhoods and health.

Anti-black Attitudes Are a Threat to Health Equity in the United States

OBJECTIVES

To assess the extent to which persistent racism shapes perspectives on public health policies aimed at improving health equity in the United States. Specifically we evaluate the relationship between implicit and explicit anti-black attitudes and support for the ACA at the beginning of the Trump administration.

METHODS

We use bivariate statistics to examine views toward the ACA, anti-black attitudes, and demographic variables. Using logistic regression, we examine how anti-black attitudes and demographic variables relate to participants stating that the ACA has worsened the quality of health care services in the United States.

SURVEY POPULATION

Data for this study come from the American National Election Studies 2016 Time Series Study, which targets US citizens age 18 and older currently living in the United States (N = 3245).

RESULTS

Implicit anti-black attitudes, particularly among whites, are strongly associated with negative feelings toward the ACA. A measure of explicit racial prejudice has the opposite relationship among whites. These results suggest that whites are most critical of the ACA when they hold positive attitudes toward blacks but hold negative stereotypes about blacks' work ethic and reject policies to eliminate racial inequalities.

CONCLUSIONS

Anti-black racial attitudes are a critical barrier to enacting health policies that stand to improve health equity in the United States. Public health practitioners and policymakers should consider racism as an essential barrier to overcome in the push for greater health equity in the United States.

Loving-kindness meditation slows biological aging in novices: Evidence from a 12-week randomized controlled trial

Combinations of multiple meditation practices have been shown to reduce the attrition of telomeres, the protective caps of chromosomes (Carlson et al., 2015). Here, we probed the distinct effects on telomere length (TL) of mindfulness meditation (MM) and loving-kindness meditation (LKM). Midlife adults (N = 142) were randomized to be in a waitlist control condition or to learn either MM or LKM in a 6-week workshop. Telomere length was assessed 2 weeks before the start of the workshops and 3 weeks after their termination. After controlling for appropriate demographic covariates and baseline TL, we found TL decreased significantly in the MM group and the control group, but not in the LKM group. There was also significantly less TL attrition in the LKM group than the control group. The MM group showed changes in TL that were intermediate between the LKM and control groups yet not significantly different from either. Self-reported emotions and practice intensity (duration and frequency) did not mediate these observed group differences. This study is the first to disentangle the effects of LKM and MM on TL and suggests that LKM may buffer telomere attrition.

Racial Discrimination, Disease Activity, and Organ Damage: The Black Women's Experiences Living With Lupus (BeWELL) Study

Black women are disproportionately affected by systemic lupus erythematosus (SLE), a chronic, potentially debilitating autoimmune disease, and they also experience more rapid progression and worse outcomes compared with other groups. We examined if racial discrimination is associated with disease outcomes among 427 black women with a validated diagnosis of SLE, who live in the Atlanta, Georgia, metropolitan area, and were recruited to the Black Women's Experiences Living with Lupus Study (2015-2017). Frequency of self-reported experiences of racial discrimination in domains such as employment, housing, and medical settings was assessed using the Experiences of Discrimination measure. SLE activity in the previous 3 months, including symptoms of fatigue, fever, skin rashes, and ulcers, was measured using the Systemic Lupus Activity Questionnaire; irreversible damage to an organ or system was measured using the Brief Index of Lupus Damage. Results of multivariable linear regression analyses examining the Systemic Lupus Activity Questionnaire and log-transformed Brief Index of Lupus Damage scores indicated that increasing frequency of racial discrimination was associated with greater SLE activity (b = 2.00, 95% confidence interval: 1.32, 2.68) and organ damage (b = 0.08, 95% confidence interval: 0.02, 0.13). Comprehensive efforts to address disparities in SLE severity should include policies that address issues of racial discrimination.

An investigation of racial/ethnic and sex differences in the association between experiences of everyday discrimination and leukocyte telomere length among patients with coronary artery disease

Leukocyte telomere length (LTL) may be sensitive to psychosocial stressors such as discrimination. An inclusive examination of experiences of discrimination on LTL across racial/ethnic and sex groups is currently lacking. Baseline data were obtained from 369 White and African American patients with coronary artery disease (CAD) in the Mental Stress Ischemia Mechanisms and Prognosis Study. LTL was measured from peripheral blood leukocytes by quantitative polymerase chain reaction and calculated in kilobase pairs. Discrimination was measured using the 10-item Everyday Discrimination Scale (EDS). Responses were rated using 4-point Likert scales ranging from never = 1 to often = 4 and summed. Regression models were stratified by race/ethnicity and sex to estimate associations between discrimination and LTL. Each 10-unit increase in experiences of everyday discrimination was associated with an average of .20 fewer kilobase pairs (or 200 base pairs) among both African American women (β = -0.19; 95% CI: -0.35, -0.04; p-value: 0.02) and White women (β = -0.19; 95% CI: -0.37, -0.01; p-value: 0.04), after adjusting for basic demographic factors. Results were similar after further adjusting for behavioral, disease, and psychosocial risk factors (depression and stress). There were no significant associations between experiences of everyday discrimination and LTL for White men or African American men. Overall, experiences of discrimination were associated with shorter LTL among women and not in men. Discrimination may be a potential source of stress associated with shorter LTL among women with CAD. Future studies should explore longitudinal associations between everyday experiences of discrimination and telomere length and also with adverse cardiovascular outcomes.

Perceived racism in relation to telomere length among African American women in the Black Women's Health Study

PURPOSE

Telomere length is considered a biomarker of human aging and premature morbidity and mortality which has been associated with chronic stress.

METHODS

We assessed the relation between perceived racism and telomere length in the Black Women's Health Study, a follow-up study of U.S. black women begun in 1995. Participants were asked about frequency of "everyday racism" (e.g., "people act as if they think you are not intelligent") and "institutional racism" (e.g., "ever treated unfairly due to race by police"). Using quantitative real-time polymerase chain reaction assay, relative telomere lengths (RTL) were measured as the copy number ratio of telomere repeat to a single control gene in 997 participants. Associations of racism variables with log-RTL were estimated by multivariable linear regression, with adjustment for age at blood draw and potential confounders.

RESULTS

Participants were aged 40-70 years (mean = 55.6 years), and mean telomere length was 0.77 (range 0.21-1.38). In stratified analyses, there was an inverse association between everyday racism and log-RTL among women who did not discuss their experiences of racism with others (β = -0.1104; 95% CI = -0.2140 to -0.0067; P = .045).

CONCLUSIONS

Everyday racism was associated with shorter telomere length among women who reported not discussing those experiences with others.

Experienced discrimination and racial differences in leukocyte gene expression

Racial disparities in health outcomes between African Americans and European Americans have been well-documented, but not fully understood. Chronic inflammation contributes to several of the diseases showing racial disparities (e.g., Human Immunodeficiency Virus [HIV]), and racial differences in stress exposure (e.g., experiences of racial discrimination) that stimulate pro-inflammatory processes that may contribute to differential health outcomes. We performed a cross-sectional bioinformatic analyses relating perceived discrimination (as measured by the Perceived Ethnic Discrimination Questionnaire [PED-Q]) to the activity of pro-inflammatory, neuroendocrine, and antiviral transcription control pathways relevant to the conserved transcriptional response to adversity (CTRA) in peripheral blood leukocytes. Subjects were 71 individuals (37 HIV-seropositive (HIV+); 34 HIV-seronegative (HIV-)) (mean age = 53 years, range 27-63), who self-identified either as African American/Black (n = 48) or European American/White (n = 23). This provided the opportunity to examine the independent effects of race and HIV, as well as the modifying role of perceived discrimination on pathways involved in CTRA. Exploratory analysis examined the interactive effects of HIV and race on pathways involved in CTRA. Relative to European Americans, African Americans showed increased activity of two key pro-inflammatory transcription control pathways (NF- кB and AP-1) and two stress-responsive signaling pathways (CREB and glucocorticoid receptor); these effects did not differ significantly as a function of HIV infection (HIV x Race interaction, all p > .10). Results suggested that differences in experiences of racial discrimination could potentially account for more than 50% of the total race-related difference in pro-inflammatory transcription factor activity. In sum, differential exposure to racial discrimination may contribute to racial disparities in health outcomes in part by activating threat-related molecular programs that stimulate inflammation and contribute to increased risk of chronic illnesses.

Cortisol and Racial Health Disparities Affecting Black Men in Later Life: Evidence From MIDUS II

In the United States, Black men have poorer overall health and shorter life spans than most other racial/ethnic groups of men, largely attributable to chronic health conditions. Dysregulated patterns of daily cortisol, an indicator of hypothalamic-pituitary-adrenal (HPA) axis stress-response functioning, are linked to poor health outcomes. Questions remain regarding whether and how cortisol contributes to Black-White differences in men's health. This exploratory study compared early day changes in cortisol levels (diurnal cortisol slopes from peak to pre-lunch levels) and their associations with medical morbidity (number of chronic medical conditions) and psychological distress (Negative Affect Scale) among 695 Black and White male participants in the National Survey of Midlife in the United States (MIDUS II, 2004-2009). Black men exhibited blunted cortisol slopes relative to White men (-.15 vs. -.21, t = -2.97, p = .004). Cortisol slopes were associated with medical morbidity among Black men (b = .050, t = 3.85, p < .001), but not White men, and were unrelated to psychological distress in both groups. Findings indicate cortisol may contribute to racial health disparities among men through two pathways, including the novel finding that Black men may be more vulnerable to some negative health outcomes linked to cortisol. Further, results suggest that while cortisol may be a mechanism of physical health outcomes and disparities among older men, it may be less important for their emotional health. This study increases understanding of how race and male sex intersect to affect not only men's lived experiences but also their biological processes to contribute to racial health disparities among men in later life.

Gender inequality and restrictive gender norms: framing the challenges to health

Gender is not accurately captured by the traditional male and female dichotomy of sex. Instead, it is a complex social system that structures the life experience of all human beings. This paper, the first in a Series of five papers, investigates the relationships between gender inequality, restrictive gender norms, and health and wellbeing. Building upon past work, we offer a consolidated conceptual framework that shows how individuals born biologically male or female develop into gendered beings, and how sexism and patriarchy intersect with other forms of discrimination, such as racism, classism, and homophobia, to structure pathways to poor health. We discuss the ample evidence showing the far-reaching consequences of these pathways, including how gender inequality and restrictive gender norms impact health through differential exposures, health-related behaviours and access to care, as well as how gender-biased health research and health-care systems reinforce and reproduce gender inequalities, with serious implications for health. The cumulative consequences of structured disadvantage, mediated through discriminatory laws, policies, and institutions, as well as diet, stress, substance use, and environmental toxins, have triggered important discussions about the role of social injustice in the creation and maintenance of health inequities, especially along racial and socioeconomic lines. This Series paper raises the parallel question of whether discrimination based on gender likewise becomes embodied, with negative consequences for health. For decades, advocates have worked to eliminate gender discrimination in global health, with only modest success. A new plan and new political commitment are needed if these global health aspirations and the wider Sustainable Development Goals of the UN are to be achieved.

The role of epigenetic aging in education and racial/ethnic mortality disparities among older U.S. Women

BACKGROUND

Higher mortality experienced by socially disadvantaged groups and/or racial/ethnic minorities is hypothesized to be, at least in part, due to an acceleration of the aging process. Using a new epigenetic aging measure, Levine DNAmAge, this study aimed to investigate whether epigenetic aging accounts for mortality disparities by race/ethnicity and education in a sample of U.S. postmenopausal women.

METHODS

1834 participants from an ancillary study (BA23) in the Women's Health Initiative, a national study that recruited postmenopausal women (50-79 years) were included. Over the 22 years of follow-up, 551 women died, and 31,946 person-years were observed. Levine DNAmAge (unit in years) was calculated based on an equation that we previously developed in an independent sample, which incorporates methylation levels at 513 CpG sites.

RESULTS

As previously reported, non-Hispanic blacks and Hispanics were epigenetically older than non-Hispanic whites of the same chronological age. Similarly, those with less education had older epigenetic ages than expected in the full sample, as well as among non-Hispanic whites and Hispanics, but not among non-Hispanic blacks. Non-Hispanic blacks and those with low education exhibited the greatest risk of mortality. However, this association was partially attenuated when accounting for differences in DNAmAge. Furthermore, formal mediation analysis suggested that DNAmAge partially mediated the mortality increase among non-Hispanic blacks, compared to non-Hispanic whites (proportion mediated, 15.8%, P = 0.002), as well as the mortality increase for those with less than high school education, compared to college educated (proportion mediated, 11.6%, P < 2E-16).

CONCLUSIONS

Among a group of postmenopausal women, non-Hispanic blacks and those with less education exhibit higher epigenetic aging, which partially accounts for their shorter life expectancies.

Association of psychosocial factors with leukocyte telomere length among African Americans in the Jackson Heart Study

Leukocyte telomere length (LTL) is a biomarker of cellular aging. African Americans report more stress than other groups; however, the association of psychosocial stressors with biological aging among African Americans remains unclear. The current study evaluated the association of psychosocial factors (negative affect and stressors) with LTL in a large sample of African American men and women (n = 2,516) from the Jackson Heart Study. Using multivariable linear regression, we examined the sex-specific associations of psychosocial factors (cynical distrust, anger in and out, depressive symptoms, negative affect summary scores, global stress, weekly stress, major life events, and stress summary scores) with LTL. Model 1 adjusted for demographics and education. Model 2 adjusted for model 1, smoking, alcohol intake, physical activity, diabetes, hypertension, and high-sensitivity C-reactive protein. Among women, high (vs. low) cynical distrust was associated with shorter mean LTL in model 1 (b = -0.12; p = 0.039). Additionally, high (vs. low) anger out and expressed negative affect summary scores were associated with shorter LTL among women after full adjustment (b = -0.13; p = 0.011; b = -0.12, p = 0.031, respectively). High levels of cynical distrust, anger out, and negative affect summary scores may be risk factors for shorter LTL, particularly among African-American women.

Salivary uric acid: Associations with resting and reactive blood pressure response to social evaluative stress in healthy African Americans

High levels of uric acid are associated with greater risk of stress-related cardiovascular illnesses that occur disproportionately among African Americans. Whether hyperuricemia affects biological response to acute stress remains largely unknown, suggesting a need to clarify this potential connection. The current study examined how salivary uric acid (sUA) is associated with resting and reactive blood pressure - two robust predictors of hypertension and related cardiovascular disease and disparity. Healthy African Americans (N = 107; 32% male; M age = 31.74 years), completed the Trier Social Stress Test to induce social-evaluative stress. Systolic and diastolic blood pressure readings were recorded before, during, and after the task to assess resting and reactive change in blood pressure. Participants also provided a saliva sample at baseline that was assayed for sUA. At rest, and controlling for age, sUA was modestly associated with higher systolic (r = .201, p =  .044), but not diastolic (r = .100, p =  .319) blood pressure. In response to the stressor task, and once again controlling for age, sUA was also associated with higher total activation of both systolic (r = .219, p =  .025) and diastolic blood pressure (r = .198, p <  .044). A subsequent moderation analysis showed that associations between sUA and BP measures were significant for females, but not for males. Findings suggest that uric acid may be implicated in hypertension and cardiovascular health disparities through associations with elevated blood pressure responses to acute social stress, and that low levels of uric acid might be protective, particularly for females.

Telomeres in neurological disorders

Ever since their discovery, the telomeres and the telomerase have been topics of intensive research, first as a mechanism of cellular aging and later as an indicator of health and diseases in humans. By protecting the chromosome ends, the telomeres play a vital role in preserving the information in our genome. Telomeres shorten with age and the rate of telomere erosion provides insight into the proliferation history of cells. The pace of telomere attrition is known to increase at the onset of several pathological conditions. Telomere shortening has been emerging as a potential contributor in the pathogenesis of several neurological disorders including autism spectrum disorders (ASD), schizophrenia, Alzheimer's disease (AD), Parkinson's disease (PD) and depression. The rate of telomere attrition in the brain is slower than that of other tissues owing to the low rate of cell proliferation in brain. Telomere maintenance is crucial for the functioning of stem cells in brain. Taking together the studies on telomere attrition in various neurological disorders, an association between telomere shortening and disease status has been demonstrated in schizophrenia, AD and depression, in spite of a few negative reports. But, studies in ASD and PD have failed to produce conclusive results. The cause-effect relationship between TL and neurological disorders is yet to be elucidated. The factors responsible for telomere erosion, which have also been implicated in the pathogenesis of neurological disorders, need to be explored in detail. Telomerase activation is now being considered as a potential therapeutic strategy for neurological disorders.

Interpersonal-level discrimination indices, sociodemographic factors, and telomere length in African-Americans and Whites

OBJECTIVE

Studies have linked self-reported discrimination to telomere attrition, a biological marker of accelerated cellular aging. However, it is unknown whether intersections between social categories-race, socioeconomic status (SES), sex, and age-influence the association of varying forms of discrimination with telomere length. We examined these associations in a socioeconomically and racially/ethnically diverse urban sample.

METHODS

Cross-sectional data were from 341 middle-aged (30-64 years) African American and White, community participants in the Healthy Aging in Neighborhoods of Diversity across the Life Span Study (HANDLS). Multiple regression models examined up to 3-way interactions between a discrimination measure (i.e., everyday, racial, gender, lifetime burden, and frequency of discrimination across sources) and two social categories.

RESULTS

After adjusting for depressive symptoms, waist circumference, and lifetime substance use, two themes emerged: 1) among women with higher SES, a) greater lifetime discrimination burden (b = -0.23, p =  .011), gender discrimination (b = -0.29, p =  .040), and racial discrimination (b = -0.24, p = 0.023) and 2) among younger adults, irrespective of race and sex, greater frequency of discrimination across sources (b = 0.002, p =  .008) was associated with shorter telomeres.

CONCLUSIONS

Irrespective of race, women with higher SES and younger adults reporting greater discrimination may be at particular risk for accelerated aging. Telomere attrition promotes and accelerates chronic health conditions for which there are health disparities. Future research explicating intersections among specific discrimination indices and social categories is warranted.

Perceived Racial Discrimination and Pain Intensity/Disability Among Economically Disadvantaged Latinos in a Federally Qualified Health Center: The Role of Anxiety Sensitivity

The present study examined the role of anxiety sensitivity (AS; fear of the negative consequences of anxiety) in the relation between perceived racial discrimination and pain-related problems among Latinos seeking health services at a Federally Qualified Health Center. Participants included 145 adult Latinos (87.80% female, Mage = 38.07 years, SD = 11.98, and 96.2% reported Spanish as their first language). Results indicated that perceived racial discrimination was indirectly related to the pain intensity and pain disability through AS. These effects were evident above and beyond the variance accounted for by gender, age, marital status, educational status, employment status, years living in the United States, and number of axis I diagnoses. Overall, the present findings highlight the merit in focusing further scientific attention on the interplay between perceived racial discrimination and AS to better understand and inform interventions to reduce pain problems among Latinos in primary care.

Racial discrimination, educational attainment, and biological dysregulation among midlife African American women

OBJECTIVE

To examine the association between self-reported racial discrimination and allostatic load, and whether the association differs by socioeconomic position.

METHODS

We recruited a purposive cross-section of midlife (ages 30-50) African American women residing in four San Francisco Bay area counties (n = 208). Racial discrimination was measured using the Experience of Discrimination scale. Allostatic load was measured as a composite of 15 biomarkers assessing cardiometabolic, neuroendocrine, and inflammatory activity. We calculated four composite measures of allostatic load and three system-specific measures of biological dysregulation. Multivariable regression was used to examine associations, while adjusting for relevant confounders.

RESULTS

In the high education group, reporting low (b = -1.09, P = .02, 95% CI = -1.99, -0.18) and very high (b = -1.88, P = .003, 95% CI = -3.11, -0.65) discrimination was associated with lower allostatic load (reference=moderate). Among those with lower education, reporting low (b = 2.05, P = .008, 95% CI = 0.55,3.56) discrimination was associated with higher allostatic load. Similar but less consistent associations were found for poverty status. Associations were similar for cardiometabolic functioning, but not for neuroendocrine or inflammatory activity.

CONCLUSIONS

Racial discrimination may be an important predictor of cumulative physiologic dysregulation. Factors associated with educational attainment may mitigate this association for African American women and other groups experiencing chronic social stress.

Multiple forms of discrimination, social status, and telomere length: Interactions within race

Previous research has demonstrated inverse associations between experiences of interpersonal discrimination and telomere length, a marker of cellular aging. Here, we investigate within-race interactions between multiple indices of interpersonal discrimination and sociodemographic characteristics in relation to telomere length in African American and White adults. Participants were from the Healthy Aging in Neighborhoods of Diversity across the Life Span study (Baltimore, Maryland). Ages ranged from 30 to 64 years old and all self-identified as either African American (n = 176) or White (n = 165). Using linear regression, three patterns were observed within African Americans: (1) women reporting greater lifetime burden of discrimination (p = .02), racial (p = .03), or gender (p = .01) discrimination; (2) those with higher socioeconomic status reporting greater lifetime burden (p = .03) or racial discrimination (p = .02); and (3) younger adults reporting greater exposure to multiple sources of discrimination (p = .03) had shorter telomere length. Among Whites, younger and older men reporting greater racial discrimination had shorter and longer telomeres, respectively (p = .02). Findings demonstrate within-race patterns of interpersonal discrimination and cellular aging, which may contribute to racial health disparities.

Perceived Unfair Treatment by Police, Race, and Telomere Length: A Nashville Community-based Sample of Black and White Men

Police maltreatment, whether experienced personally or indirectly through one's family or friends, represents a structurally rooted public health problem that disproportionately affects minorities. Researchers, however, know little about the physiological mechanisms connecting unfair treatment by police (UTBP) to poor health. Shortened telomeres due to exposure to this stressor represent one plausible mechanism. Using data from a community sample of black (n = 262) and white (n = 252) men residing in Nashville-Davidson County, we test four hypotheses: (1) Black men will be more likely to report UTBP than white men, (2) those reporting UTBP will have shorter telomeres than those not reporting UTBP, (3) this association will be more pronounced among black men, and (4) these hypotheses will extend to those who report vicarious UTBP. Results reveal support for all hypotheses. The implications for our findings are discussed as they pertain to debates on policing practices and health disparities research.

"I Feel Trapped": The Tension Between Personal and Structural Factors of Social Isolation and the Desire for Social Integration Among Older Residents of a High-Crime Neighborhood

Background and Objectives

The aim of this study was to examine the factors contributing to the social isolation of older residents of a high-crime neighborhood through the in-depth examination of their lived experiences. A deeper understanding of factors contributing to social isolation can allow policymakers and health care providers to create policies and programs to alleviate the social isolation of these vulnerable and understudied individuals.

Research Design and Methods

Participants were recruited through the support of the Housing Authority and Police and Fire Departments of Richmond, California, a town with a high-crime rate. Fifty-nine ethnographic interviews were conducted with 20 individuals of 58-95 years of age. Transcripts and fieldnotes were analyzed with a focus on the specific factors contributing the social isolation of participants.

Results

An overarching theme of tension between personal and structural factors of social isolation and desire for social integration emerged from qualitative content analysis. A tension emerged between a longing to participate in society and the immersion in a reality so dense with obstacles that made participation in society difficult to attain. Four specific themes also emerged. Three themes demonstrated underlying factors of social isolation stemming from the personal sphere and the physical and social environment. The fourth theme illustrated participants' desire for social integration.

Discussion and Implications

Findings demonstrate the salience of interventions and programs to make neighborhoods safe and accessible to older residents. Findings also suggest a need to reframe the conceptual framework for social isolation to better measure and alleviate this public health problem.

A scoping systematic review of social stressors and various measures of telomere length across the life course

Numerous studies examine the relationship between social stressors and telomere length (TL). Beyond considering methods and major findings, this scoping systematic review takes a novel approach as it groups studies according to the types of social stressor considered and by age groups. Following PRISMA guidelines, we searched PubMed, Web of Science, Embase, and Scopus. We included all English-language human subject research articles that modeled any measure of TL as a dependent variable and exposure to a social stressor as an independent variable. For the sample of 105 articles, we summarized methods and findings by type of social stressor (socioeconomic stressors, stressful life events, work-related stressors, and neighborhood stressors) and by age of the study population (infants/children, middle-aged adults, older adults, and mixed samples of middle-aged and older adults). We found more variation in TL measurement methodology in studies of infants/children and older adults than in studies focusing on middle-aged adults. The most consistent finding was a relationship between early-life stressors and shorter TL. Work and neighborhood stressors, and older populations, are currently understudied. Across all stressors, limited evidence suggests that the stress-TL relationship may be moderated by characteristics such as age, sex, and race/ethnicity. We conclude with specific suggestions for future research.

Justice for all? Beliefs about justice for self and others and telomere length in African Americans

OBJECTIVE

Believing in justice can protect health. Among marginalized racial minorities however, both endorsing and rejecting beliefs about justice might be critical. The current research examined links between African Americans' beliefs about justice for self and for others and telomere length (TL)-an indicator of biological aging that is increasingly implicated in racial health disparities, with shorter telomeres indicating poorer health.

METHOD

Healthy African Americans (N = 118; 30% male; M age = 31.63 years) completed individual differences measures of justice beliefs for self and others and then provided dried blood spot samples that were assayed for TL.

RESULTS

We expected that a belief in justice for self would be positively associated with TL, whereas a belief in justice for others would be negatively associated. A significant 3-way interaction with chronological age confirmed this hypothesis-among older African Americans, TL was positively associated with believing in justice for self, but only when this belief was accompanied by a weak endorsement of the belief in justice for others.

CONCLUSION

Findings underscore that for racial minorities, health might be best protected when justice beliefs are both endorsed and rebuffed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Racial disparities in renal function: the role of racial discrimination. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

Background

Racial discrimination may play a significant role in higher incidence and poorer prognosis of chronic kidney disease among Black individuals. This study set out to investigate the association between racial discrimination and renal function and to estimate the contribution of racial discrimination to existing racial disparities in renal function.

Methods

A cross-sectional analysis using baseline data (2008–2010) of 14 355 participants (35–74 years) in the Brazilian Longitudinal Study of Adult Health cohort study. Renal function was estimated based on estimated glomerular filtration rates (eGFR) obtained by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Racial discrimination was assessed using a modified version of the Lifetime Major Events Scale ; race/colour was self-reported. Covariates included were age, sex, level of education and selected health-related factors.

Results

Racial discrimination was reported by 31.6%, 6.3% and 0.8% of Black, Brown and White individuals, respectively. The older the age, the lower the prevalence of racial discrimination among Blacks. Racial discrimination was independently associated with lower mean eGFR (β=−2.38; 95% CI −3.50 to −1.25); however, associations were limited to individuals aged under 55 years. In this age group, eGFR differences between Black and White individuals were reduced by 31% when exposure to racial discrimination was accounted for.

Conclusion

Blacks are approximately 40 times more likely to report racial discrimination than Whites. Racial discrimination was associated with lower mean eGFR and explained a significant portion of eGFR differences between Black and White individuals aged under 55 years. Exposure to experiences of racial discrimination should be accounted for in studies investigating racial disparities in renal function.

The Relation Between Discrimination, Sense of Coherence and Health Varies According to Ethnicity: A Study Among Three Distinct Populations in Israel

Self-reported experiences of discrimination and sense of coherence (SOC) have been found to be associated with health. A face-to-face survey of Long Term Jewish Residents (LTJR), Arabs and former Soviet Union (fSU) immigrants in Israel was performed. Respondents reported their physical and mental health, self-reported experiences of discrimination, SOC and socioeconomic status. Multivariable logistic regressions and bootstrapping path analyses were performed. Discrimination was associated with health after adjusting for all other variables. SOC was also associated with health. SOC did not mediate the strong association between discrimination and health among Israeli LTJR, but was a significant mediator among Arabs and fSU immigrants. Discrimination seems to have a direct effect on health only among the majority and not among minority populations. High levels of SOC may reduce the negative effects of discrimination on health by serving as a coping resource, however only among minorities.

Stress-Related Biosocial Mechanisms of Discrimination and African American Health Inequities

This review describes stress-related biological mechanisms linking interpersonal racism to life course health trajectories among African Americans. Interpersonal racism, a form of social exclusion enacted via discrimination, remains a salient issue in the lives of African Americans, and it triggers a cascade of biological processes originating as perceived social exclusion and registering as social pain. Exposure to discrimination increases sympathetic nervous system activation and upregulates the HPA axis, increasing physiological wear and tear and elevating the risks of cardiometabolic conditions. Consequently, discrimination is associated with morbidities including low birth weight, hypertension, abdominal obesity, and cardiovascular disease. Biological measures can provide important analytic tools to study the interactions between social experiences such as racial discrimination and health outcomes over the life course. We make future recommendations for the study of discrimination and health outcomes, including the integration of neuroscience, genomics, and new health technologies; interdisciplinary engagement; and the diversification of scholars engaged in biosocial inequities research.

Weathering the storm; a review of pre-pregnancy stress and risk of spontaneous abortion

The Weathering Effect is a theory that links stress exposure, over the life-course, with racial disparities in reproductive outcomes, through the effects of social adversity on a woman's body. The concept of maternal "weathering" captures cumulative somatic and psychological adversities that can exacerbate the effects of aging. Much of the evidence for weathering comes from observational studies linking self-report measures with reproductive outcomes. The purpose of this review is to explore biological mechanisms that underlie these observations. We focus on spontaneous abortion because this event is understudied despite evidence of racial disparities in this outcome. Spontaneous abortion is the most common pregnancy failure, and it happens early in pregnancy. Early pregnancy is a time most susceptible to the harmful effects of immune dysregulation that may, in part, result from adversities experienced before pregnancy begins. In exploring these mechanisms, we draw on well-defined signaling processes observed in the stressor-depression relationship. Pro-inflammatory dysregulation, for example, has particular relevance to immunological control occurring early in pregnancy. Early pregnancy immunologic changes affect the trajectories of pregnancy via control of trophoblastic invasion. Within the first few weeks of pregnancy, uterine derived cytokines operate within cytokine networks and play a critical role in this invasion. Programming for pro-inflammatory dysregulation can occur before conception. This dysregulation, brought into early pregnancy, has implications for viability and success of the index pregnancy. These patterns suggest early pregnancy health is susceptible to stress processing pathways that influence this immunologic control in the first six to eight weeks of pregnancy. In this review, we discuss the known mediating role of immune factors in the stressor-depression relationship. We also discuss how adversity experienced before the index pregnancy, or "pre-pregnancy" may influence these pathways, and subsequently influence early pregnancy health. There is a need to understand adversity, experienced before pregnancy, and mechanisms driving the effects of these experiences on pregnancy outcomes. This approach is a useful entry point for understanding racial inequities in pregnancy health through an understanding of differences in exposures to adversity. We hypothesize that spontaneous abortion involves cyclical changes within a woman's reproductive tract in response to stressors that are established well before a woman enters into pregnancy. Furthermore, we propose mechanisms that potentially drive weathering processes relevant to reproductive disparities. We also examine what is known about pre-pregnancy stress exposures associated with race, inequity, and adversity, and their potential impact on neuroendocrine and immune changes affecting early pregnancy risk.

Income and Self-Rated Mental Health: Diminished Returns for High Income Black Americans

Background: The minorities' diminished return theory suggests that socioeconomic position (SEP) generates smaller health gains for racial/ethnic minorities compared to Whites. The current study was a Black⁻White comparison of the association between household income and self-rated mental health (SRMH). Methods: This cross-sectional study used data from the 2017 State of the State Survey (SOSS). With representative sampling, the SOSS generates results that are generalizable to the state of Michigan. This study included 881 adults, (n = 92) Black and (n = 782) White. The independent variable was household income. The dependent variable was SRMH, measured using a single item. Age, gender, and participation in the labor force were covariates. Race/ethnicity was the focal moderator. Logistic regression models were used for data analysis. Results: Overall, higher household income was associated with better SRMH, net of covariates. An interaction was found between race/ethnicity and household income on SRMH, suggesting a smaller, or nonexistent, protective effect for Blacks compared to Whites. In race/ethnicity-stratified models, higher household income was associated with better SRMH for Whites but not Blacks. Conclusion: Supporting the minorities' diminished return theory, our study documents differential effects for income on SRHM for Blacks and Whites, where Whites but not Blacks appear to benefit from their income. Given this, researchers and policy makers are cautioned against making assumptions that racial groups benefit equally from similar economic resources.

Perceived Interpersonal Discrimination and Older Women's Mental Health: Accumulation Across Domains, Attributions, and Time

Experiencing discrimination is associated with poor mental health, but how cumulative experiences of perceived interpersonal discrimination across attributes, domains, and time are associated with mental disorders is still unknown. Using data from the Study of Women’s Health Across the Nation (1996–2008), we applied latent class analysis and generalized linear models to estimate the association between cumulative exposure to perceived interpersonal discrimination and older women’s mental health. We found 4 classes of perceived interpersonal discrimination, ranging from cumulative exposure to discrimination over attributes, domains, and time to none or minimal reports of discrimination. Women who experienced cumulative perceived interpersonal discrimination over time and across attributes and domains had the highest risk of depression (Center for Epidemiologic Studies Depression Scale score ≥16) compared with women in all other classes. This was true for all women regardless of race/ethnicity, although the type and severity of perceived discrimination differed across racial/ethnic groups. Cumulative exposure to perceived interpersonal discrimination across attributes, domains, and time has an incremental negative long-term association with mental health. Studies that examine exposure to perceived discrimination due to a single attribute in 1 domain or at 1 point in time underestimate the magnitude and complexity of discrimination and its association with health.
