The Relationship Between Perceived Racism/Discrimination and Health Among Black American Women: a Review of the Literature from 2003 to 2013

Disparities in perinatal COVID-19 infection and vaccination

The COVID-19 pandemic exposed and exacerbated persistent health inequities in perinatal populations, resulting in disparities of maternal and fetal complications. In this narrative review, we present an adapted conceptual framework of perinatal social determinants of health in the setting of the COVID-19 pandemic and use this framework to contextualize the literature regarding disparities in COVID-19 vaccination and infection. We synthesize how elements of the structural context, individual socioeconomic position, and concrete intermediary determinants influence each other and perinatal COVID-19 vaccination and infection, arguing that systemic inequities at each level contribute to observed disparities in perinatal health outcomes. From there, we identify gaps in the literature, propose mechanisms for observed disparities, and conclude with a discussion of strategies to mitigate them.

Nursing student perceptions of racism and health disparities in the United States: A critical race theory perspective

BACKGROUND

Limited research has been done on nursing students' awareness of racial disparities and their readiness to address bias and racism in clinical practice.

PURPOSE

This study investigated nursing students' perceptions of how racial disparities affect health outcomes, including maternal outcomes, in the United States.

METHODS

Interpretive description was used and supported by the critical race theory as a framework to guide the data collection, analysis, and interpretation to understand participants' perceptions surrounding racism and health disparities.

DISCUSSION

Nurse educators should guide students to look beyond individual behavioral and risk factors and consider systemic issues as a leading contributors to health disparities.

CONCLUSION

The most critical finding was the lack of participants' understanding of systemic racism and its impact on health disparities. While they often attributed racial disparities to low socioeconomic status and lack of education, they did not understand the relationships between social determinants of health and systemic racism.

Harmonizing Assessments of Everyday Racial Discrimination Experiences: The Multigroup Everyday Racial Discrimination Scale (MERDS)

Reliable and valid assessment of direct racial discrimination experiences in everyday life is critical to understanding one key determinant of ethnoracial minority health and health disparities. To address psychometric limitations of existing instruments and to harmonize the assessment of everyday racial discrimination, the new Multigroup Everyday Racial Discrimination Scale (MERDS) was developed and validated. This investigation included 1,355 college and graduate students of color (Mage = 21.54, 56.0% women). Factor analyses were performed to provide evidence for structural validity of everyday racial discrimination scores. Item response theory modeling was used to investigate item difficulty relative to the level of everyday racial discrimination, and measurement error conditioned on the construct. MERDS scores were reliable, supported construct unidimensionality, and distinguished individuals who reported low to very high frequency of everyday racial discrimination. Results on the associations with racial identity and psychopathology symptoms, and utility of the scale are discussed.

Discrimination and bladder health among women in the CARDIA cohort study: Life course and intersectionality perspectives

OBJECTIVE

This study examines whether discriminatory experiences are associated with lower urinary tract symptoms (LUTS) and their impact among 972 women in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study, which recruited participants from 4 cities in the United States.

METHOD

Exposure to discrimination was assessed 3 times (1992-93, 2000-01, 2010-11) and averaged across assessments. Participants separately reported whether they experienced discrimination on the basis of their gender, race or color, and socioeconomic position or social class. For each social identity, discrimination was assessed in 6-7 settings (e.g., when getting a job, medical care, or housing). At different time points, women who reported discriminatory experiences for a given social identity were asked how frequently the discrimination occurred and how stressful experience(s) were. Following the 2010-11 assessment, data on LUTS and their impact were collected. Women were classified into bladder health versus mild, moderate, or severe symptoms/impact clusters.

RESULTS

More Black than White women reported discriminatory experiences across all social identities and most settings. Perceived stress of discriminatory experiences did not differ between Black and White women. In analyses stratified by race and social identity, White women reported LUTS/impact with discriminatory experiences in more settings, more frequent discriminatory experiences across settings, and each additional social identity for which discrimination was experienced. Black women reported LUTS/impact with more frequent discriminatory experiences across settings. For Black women, greater perceived stress of both gender and race discrimination were associated with LUTS/impact. For White women, only greater perceived stress of race discrimination was associated with LUTS/impact.

CONCLUSIONS

This is one of the first studies to examine discrimination in relation to LUTS/impact. Additional research is needed to better understand differences in how discriminatory experiences based on potentially intersecting identities may be related to bladder health among women.

Associations among discrimination, psychological functioning, and substance use among US Black adults aged 18-28: Moderation by racial attribution and sex

INTRODUCTION

Discrimination is associated with poor mental health and substance use among Black Americans, but research is needed on mediators and moderators of these relationships. This study tested whether: 1) discrimination is associated with current alcohol, tobacco (cigarette or e-cigarette), and cannabis use among US Black emerging adults; 2) psychological distress (PD) and positive well-being (PW) are mediators of discrimination-substance use relationships; and 3) these relationships are moderated by sex and attributions to discrimination (racial vs. nonracial).

METHODS

Using data from a 2017 US nationally representative survey, we conducted bivariate and multiple-group moderated mediation analyses among 1118 Black American adults aged 18-28. The study assessed discrimination and attribution to discrimination using the Everyday Discrimination scale, past 30-day PD with the Kessler-6 scale, and past 30-day PW with the Mental Health Continuum Short Form. We utilized probit regression for all structural equation models and adjusted final models for age.

RESULTS

Discrimination was positively associated with past 30-day cannabis and tobacco use directly and indirectly through PD in the overall model. Among males who reported race as the sole/main attribution to discrimination, discrimination was positively associated with alcohol, cannabis, and tobacco use through PD. Among females who reported race as the sole/main attribution to discrimination, discrimination was positively associated with cannabis use through PD. Discrimination was positively associated with tobacco use among those who reported nonracial attributions to discrimination and with alcohol use among those whose attribution was not assessed. Discrimination was positively associated with PD among those who reported race as a secondary attribution to discrimination.

CONCLUSIONS

Discrimination specifically attributed to race may contribute to greater PD and in turn alcohol, cannabis, and tobacco use among Black emerging adults, especially males. Future substance use prevention and treatment efforts targeted to Black American emerging adults may benefit from addressing racial discrimination and PD.

A Systematic Review of Interpersonal Interactions Related to Racism in Studies Assessing Breast and Gynecological Cancer Health Outcomes Among Black Women

OBJECTIVE

To identify how studies measure racism-related variables at the interpersonal level and identify associated breast and gynecological cancer disparities among Black women.

METHODS

A systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Searches were conducted in PubMed, CINAHL Plus, and Scopus using terms centered on racism and cancer. Inclusion criteria consisted of the study being conducted in the USA with Black or African American women and the study stating an outcome or focus identified as a breast or gynecological cancer health disparity. Two researchers independently screened titles and abstracts and full texts articles and completed quality assessments of included studies. Data were extracted into a matrix table, and common concepts were identified and synthesized using the matrix method. The quality of included studies was assessed using the Joanna Briggs Institute's critical appraisal tools.

RESULTS

Thirteen studies that examined the effect of racism-related variables operating at the interpersonal level on breast, cervical, and ovarian cancer outcomes in Black women were identified for inclusion. Across studies, racism-related variables were measured as discrimination, trust, racism, and clinician-patient interactions. Additionally, across studies, disparities were identified in cancer screening, treatment received, survivorship quality of life, and incidence.

CONCLUSION

This review highlights the need for valid, reliable, and consistent measurement of racism operating at the interpersonal level to first understand its impact on cancer health disparities and to also facilitate the development and evaluation of interventions aimed at mitigating interpersonal-level racism.

Spatialising urban health vulnerability: An analysisof NYC's critical infrastructure during COVID-19

This paper examines how fragmentation of critical infrastructure impacts the spread of the coronavirus outbreak in New York City at the neighbourhood level. The location of transportation hubs, grocery stores, pharmacies, hospitals and parks plays an important role in shaping spatial disparities in virus spread. Using supervised machine learning and spatial regression modelling we examine how the geography of COVID-19 case rates is influenced by the spatial arrangement of four critical sectors of the built environment during the public health emergency in New York City: health care facilities, mobility networks, food and nutrition and open space. Our models suggest that an analysis of urban health vulnerability is incomplete without the inclusion of critical infrastructure metrics in dense urban geographies. Our findings show that COVID-19 risk at the zip code level is influenced by (1) socio-demographic vulnerability, (2) epidemiological risk, and (3) availability and access to critical infrastructure.

Overlap between birth trauma and mistreatment: a qualitative analysis exploring American clinician perspectives on patient birth experiences

INTRODUCTION

Research exploring the mistreatment of birthing people in the United States is emerging rapidly within the context of increasingly poor maternal health outcomes that include unacceptable racial disparities. Previous research has explored overlap between psychological birth trauma and mistreatment using patient descriptions of birth experiences, but no previous studies have explored these issues from the perspectives of clinicians. The aim of this study was to explore whether maternity care providers' descriptions of patient birth trauma overlap with categories of mistreatment from a globally accepted typology.

METHODS

Content analysis was performed on a qualitative data set of 28 semi-structured interviews about patient birth trauma, completed in 2018-2019 with U.S. maternity care clinicians, including obstetricians, family physicians, midwives and labor/delivery nurses. The interviews were part of a larger study exploring maternity clinician perspectives and experiences of patient birth trauma. For this analysis Krippendorff's method of categoric distinction was used, with categories from a globally recognized typology of maternity patient mistreatment.

RESULTS

Clinicians' descriptions of their experiences with patient birth trauma mapped onto all seven mistreatment categories, although no interview questions specifically asked about mistreatment. In more than 30 hours of interviews, transcribed to more than 800 pages, the word mistreatment appears only once, suggesting that some healthcare providers may use the phrase "birth trauma" as a euphemism to describe mistreatment. Eighteen of 28 interviews included at least one description that fit into a mistreatment category. "Failure to meet professional standards of care" was the category with the most mapped clinician statements, followed by "Stigma and discrimination" and "Poor rapport between women and providers."

CONCLUSIONS

This study contributes new insight into maternity clinicians' conceptualization of patient trauma and how their descriptions of birth trauma overlap with mistreatment. Clinicians implicitly connected mistreatment with some patient experiences of birth trauma, even when they were not specifically asked about mistreatment. Findings point to a need for further research into mistreatment, including routinized "everyday care" that may include mistreatment, particularly for marginalized and historically excluded birthing people. Future research also must explore the potential role of mistreatment in poor and inequitable U.S. birth outcomes.

A review of African American women's experiences in menopause

IMPORTANCE AND OBJECTIVE

Little is known and reported about the experiences of African American women as they transition to and experience menopause. Accepted norms are based on the experience of a predominantly White population. The aim of this study is to review available data about the distinct experiences of African American women during the menopause transition and menopause.

METHODS

A literature search was developed and executed by the review team in collaboration with a health sciences librarian. The search combined controlled vocabulary and title/abstract terms related to the health status disparities of African Americans in the menopause transition and menopause. The following databases were searched from inception through April 28, 2022: PubMed, Scopus (Elsevier), and Web of Science Core Collection (Clarivate).

DISCUSSION AND CONCLUSION

African American women experience distinct differences in physical, psychological, social, and quality of life measures during menopause. Increasing awareness about the unique menopause experiences of African American women is critically important to improve the health of this underserved population.

Measurement considerations in the link between racial/ethnic discrimination and adolescent well-being: A meta-analysis

Racial/ethnic discrimination is a commonplace experience for many adolescents of color, and an increasing number of studies over the past 25 years have sought to document discrimination and its consequences at this stage of the life course. The evidence is clear and convincing that racial/ethnic discrimination is harmful for adolescents' socioemotional and behavioral well-being as well as their academic success. Discrimination measurement, however, poses a critical source of potential variation in the observed effect sizes capturing the associations between racial/ethnic discrimination and adolescents' well-being. This meta-analysis integrated 1,804 effect sizes on 156,030 unique ethnically- and geographically-diverse adolescents (M age = 14.44, SD = 2.27) from 379 studies that used 79 unique instruments to assess racial/ethnic discrimination. The meta-analysis focused on a host of measurement-related moderators, including the number of items, response scale and response dimensions, reliability, retrospective reference period, perpetrators, and initial target populations. Larger effect sizes were observed for instruments with more items and with non-dichotomously rated items. Perpetrator and retrospective reference period also emerged as key moderators, while measure reliability, response dimensions, and initial measurement development characteristics were not significant moderators. Findings provide key insights for the development of more precise, effective instruments to assess perceived racial/ethnic discrimination in adolescence.

Psychological Resilience, Cardiovascular Disease, and Metabolic Disturbances: A Systematic Review

Background

Positive psychosocial factors can play an important role in the development of cardiovascular disease (CVD). Among them, psychological resilience (PR) is defined as the capacity of responding positively to stressful events. Our aim was to assess whether PR is associated with CVD or metabolic disturbances through a systematic review.

Methods

We gathered articles from PubMed, Web of Science, PsycInfo, and Google Scholar up to October 28, 2021. We included articles that were in English, were observational, and had PR examined as exposure. The CVD outcomes were either clinical or metabolic outcomes (i.e., dyslipidemia, obesity, metabolic syndrome, hypertension, and diabetes).

Results

Our literature search identified 3,800 studies, of which 17 met the inclusion criteria. Of them, seven were longitudinal and 10 cross-sectional, and 13 were on adults and four on children. The exposure assessment was heterogeneous, i.e., 12 studies used different kinds of self-administered questionnaires and five used interviews with a psychologist. Regarding outcomes, five studies investigated CVD, seven obesity, one metabolic syndrome, two hypertension, four dyslipidemia, and four diabetes. In longitudinal studies, PR was found to have an inverse association with included outcomes in five studies from the Swedish military conscription cohort but had no association with CVD in a study on African-American women and was associated with slower progression of diabetes in a general population. The cross-sectional studies showed that the prevalence of disease was not associated with PR in many cases but the progression of disease was associated with PR.

Conclusion

PR seems to have a possibly favorable association with CVD and metabolic disturbances that differs according to the type of outcome and population. Our study limitations are given by the small number of studies available and the heterogeneity in PR measurement.

Risk Patterns and Mortality in Postmenopausal Women Using Latent Class Analysis

INTRODUCTION

Although risk factors often co-occur, previous studies examining lifestyle or psychosocial factors often treat these factors as individual predictors of health. This study aims to identify the underlying subgroups of women characterized by distinct lifestyle and psychosocial risk patterns and to investigate the prospective associations between risk patterns and mortality among postmenopausal women.

METHODS

A total of 64,812 postmenopausal women aged 50-79 years without prevalent diabetes, cardiovascular disease, and cancer at baseline (1993-1998) were followed until 2019 with a mean follow-up duration of 14.6 (SD=6.4) years. Latent class analysis was used to identify the latent classes of women with homogeneous combinations of lifestyle and psychosocial variables and to test whether the classes were prospectively associated with mortality. Analyses were stratified by race/ethnicity and were performed in 2020.

RESULTS

A total of 4 latent classes (Healthy Lifestyle and Psychosocial, Risky Psychosocial, Risky Lifestyle, and Risky Lifestyle and Risky Psychosocial) were identified for Hispanic, Black, and White women, and 2 classes (High Risk or Low Risk) were identified for American Indian and Asian women. Women in the Risky Lifestyle and Risky Psychosocial group had the highest hazard ratios for all outcomes studied for all race/ethnicity groups than those in the Healthy Lifestyle and Psychosocial group, followed by those in the Risky Lifestyle group. Risky Psychosocial class was significantly associated with an elevated risk of overall and cardiovascular disease mortality only in Black women.

CONCLUSIONS

The class with concurrent risky lifestyle and psychosocial factors conveyed the greatest risk of all types of mortality than a low-risk ref group. Health promotion should address both behavioral and psychosocial risks concurrently.

Perceived Racial Discrimination in the Pregnant African American Population: A Concept Analysis

African American women experience higher lifetime exposure to chronic stressors, such as perceived racial discrimination. Clearly defining perceived racial discrimination in the pregnant African American population has the potential to better explain the phenomenon and how it relates to adverse birth outcomes such as preterm birth. The purpose of this concept analysis is to more clearly define perceived racial discrimination in the pregnant African American population using Rodgers' evolutionary method. Defining the concept of interest has the potential to uncover modifiers that may help close the gap in the Black-White infant mortality rates in the United States.

A robust time delay estimation method for ultrasonic echo signals and elastography

Modern medicine cannot ignore the significance of elastography in diagnosis and treatment plans. Despite improvements in accuracy and spatial resolution of elastograms, robustness against noise remains a neglected attribute. A method that can perform in a satisfactory manner under noisy conditions may prove useful for various elastography methods. Here, we propose a method based on eigenvalue decomposition (EVD). In this method, the estimated time delay is defined as the index of the maximum element in the eigenvector that corresponds to the minimum eigenvalue in the covariance matrix of the received signal. Moreover, the implementation of the least-squares (LS) solution and the lower-upper (LU) decomposition contributes to improving the speed of computation and the accuracy of the estimation under low signal-to-noise ratio (SNR) conditions. To assess the performance of the proposed algorithm, it is evaluated along with generalized cross-correlation (GCC) and EVD. The simulation results clearly confirm that the jitter variance achieved in the proposed algorithm outperforms GCC and EVD in the proximity of the Cramer-Rau lower band. Moreover, our algorithm provides satisfactory performance in terms of variance and bias against sub-sample delay at low SNRS. According to the experimental results, the calculated values of the elastographic signal-to-noise ratio (SNRe) and the elastographic contrast-to-noise ratio (CNRe) of the proposed algorithm were 16.7 and 20.09, respectively, clearly better than the values of the other two methods. Furthermore, the proposed algorithm offers less execution time (about 30% of GCC), with a computational complexity equal to GCC and better than EVD.

Working Agenda for Black Mothers: A Position Paper From the Association of Black Cardiologists on Solutions to Improving Black Maternal Health

Following decades of decline, maternal mortality began to rise in the United States around 1990—a significant departure from the world’s other affluent countries. By 2018, the same could be seen with the maternal mortality rate in the United States at 17.4 maternal deaths per 100 000 live births. When factoring in race/ethnicity, this number was more than double among non-Hispanic Black women who experienced 37.1 maternal deaths per 100 000 live births. More than half of these deaths and near deaths were from preventable causes, with cardiovascular disease being the leading one. In an effort to amplify the magnitude of this epidemic in the United States that disproportionately plagues Black women, on June 13, 2020, the Association of Black Cardiologists hosted the Black Maternal Heart Health Roundtable—a collaborative task force to tackle the maternal health crisis in the Black community. The roundtable brought together diverse stakeholders and champions of maternal health equity to discuss how innovative ideas, solutions and opportunities could be implemented, while exploring additional ways attendees could address maternal health concerns within the health care system. The discussions were intended to lead the charge in reducing maternal morbidity and mortality through advocacy, education, research, and collaborative efforts. The goal of this roundtable was to identify current barriers at the community, patient, and clinician level and expand on the efforts required to coordinate an effective approach to reducing these statistics in the highest risk populations. Collectively, preventable maternal mortality can result from or reflect violations of a variety of human rights—the right to life, the right to freedom from discrimination, and the right to the highest attainable standard of health. This is the first comprehensive statement on this important topic. This position paper will generate further research in disparities of care and promote the interest of others to pursue strategies to mitigate maternal mortality.

"Just Because You Have Ears Doesn't Mean You Can Hear"-Perception of Racial-Ethnic Discrimination During Childbirth

Background

Black and Latina women in New York City are twice as likely to experience a potentially life-threatening morbidity during childbirth than White women. Health care quality is thought to play a role in this stark disparity, and patient-provider communication is one aspect of health care quality targeted for improvement. Perceived health care discrimination may influence patient-provider communication but has not been adequately explored during the birth hospitalization.

Purpose

Our objective was to investigate the impact of perceived racial-ethnic discrimination on patient-provider communication among Black and Latina women giving birth in a hospital setting.

Methods

We conducted four focus groups of Black and Latina women (n=27) who gave birth in the past year at a large hospital in New York City. Moderators of concordant race/ethnicity asked a series of questions on the women's experiences and interactions with health care providers during their birth hospitalizations. One group was conducted in Spanish. We used an integrative analytic approach. We used the behavioral model for vulnerable populations adapted for critical race theory as a starting conceptual model. Two analysts deductively coded transcripts for emergent themes, using constant comparison method to reconcile and refine code structure. Codes were categorized into themes and assigned to conceptual model categories.

Results

Predisposing patient factors in our conceptual model were intersectional identities (eg, immigrant/Latina or Black/Medicaid recipient), race consciousness ("…as a woman of color, if I am not assertive, if I am not willing to ask, then they will not make an effort to answer"), and socially assigned race (eg, "what you look like, how you talk"). We classified themes of differential treatment as impeding factors, which included factors overlooked in previous research, such as perceived differential treatment due to the relationship with the infant's father and room assignment. Themes for differential treatment co-occurred with negative provider communication attributes (eg, impersonal, judgmental) or experience (eg, not listened to, given low priority, preferences not respected).

Conclusions

Perceived racial-ethnic discrimination during childbirth influences patient-provider communication and is an important and potentially modifiable aspect of the patient experience. Interventions to reduce obstetric health care disparities should address perceived discrimination, both from the provider and patient perspectives.

An Anti-Racist Approach to Achieving Mental Health Equity in Clinical Care

Racism is an important determinant of health and health disparities, but few strategies have been successful in eliminating racial discrimination from medical practice. This article proposes a novel antiracist approach to clinical care that acknowledges the racism shaping the clinical encounter and historical arc of racial oppression embedded in health care. Although preliminary, this approach can be easily implemented into clinical care and may reduce the harm done by racism. It could also serve as a template for antiracist service provision in other sectors, such as education and law enforcement.

Resilience and CVD-protective Health Behaviors in Older Women: Examining Racial and Ethnic Differences in a Cross-Sectional Analysis of the Women's Health Initiative

Little is known about the relationship between self-reported psychological resilience (resilience) and health behaviors shown to reduce the risk of cardiovascular disease (CVD). This study examines the associations between resilience and CVD-related risk factors, such as diet, smoking, physical activity, sleep, and alcohol consumption among older American women from diverse backgrounds.

METHODS

A cross-sectional secondary analysis was conducted on 77,395 women (mean age 77 years, Black (N = 4475, 5.8%), non-Hispanic white (N = 69,448, 89.7%), Latina (N = 1891, 2.4%), and Asian or Pacific Islander (N = 1581, 2.0%)) enrolled in the Women's Health Initiative Extension Study II. Resilience was measured using an abbreviated version of the brief resilience scale. Multivariable logistic regression models were used to evaluate the association between resilience and health behaviors associated with risk for CVD, while adjusting for stressful life events and sociodemographic information. To test whether these associations varied among racial/ethnic groups, an interaction term was added to the fully adjusted models between resilience and race/ethnicity.

RESULTS

High levels of resilience were associated with better diet quality (top 2 quintiles of the Healthy Eating Index 2015) (OR = 1.22 (95% Confidence Interval (1.15-1.30)), adhering to recommended physical activity (≥ 150 min per week) (1.56 (1.47, 1.66)), sleeping the recommended hours per night (7-9) (1.36 (1.28-1.44)), and moderate alcohol intake (consuming alcoholic drink(s) 1-7 days per week) (1.28 (1.20-1.37)). The observed association between resilience and sleep is modified by race/ethnicity (p = 0.03).

CONCLUSION

Irrespective of race/ethnicity, high resilience was associated with CVD-protective health behaviors. This warrants further investigation into whether interventions aimed at improving resilience could increase the effectiveness of lifestyle interventions.

A Moderated Mediation Analysis on the Association Between Perceived Discrimination and Physical Symptoms Among Immigrant Women from Mainland China into Hong Kong: Evidence from the FAMILY Cohort

With a research focus on the possible impact of perceived discrimination on physical symptoms, this study examined a moderated mediation model that depressive symptoms would mediate the association between perceived discrimination and physical symptoms, and family satisfaction would show moderating effects on both depressive and physical symptoms among immigrants. Immigrant women from Mainland China into Hong Kong (N = 966) completed a cross-sectional survey. Depressive symptoms mediated the association between perceived discrimination and physical symptoms. Family satisfaction moderated the association between perceived discrimination and depressive symptoms that participants with lower family satisfaction showed a stronger association. However, family satisfaction did not moderate with perceived discrimination or depressive symptoms to predict physical symptoms. Our findings demonstrated the health consequences of perceived discrimination. Development of resilience programs, particularly with a focus of strengthening family resources, may in tandem help immigrants manage their experiences with discrimination.

The Association Between State-Level Racial Attitudes Assessed From Twitter Data and Adverse Birth Outcomes: Observational Study

Background

In the United States, racial disparities in birth outcomes persist and have been widening. Interpersonal and structural racism are leading explanations for the continuing racial disparities in birth outcomes, but research to confirm the role of racism and evaluate trends in the impact of racism on health outcomes has been hampered by the challenge of measuring racism. Most research on discrimination relies on self-reported experiences of discrimination, and few studies have examined racial attitudes and bias at the US national level.

Objective

This study aimed to investigate the associations between state-level Twitter-derived sentiments related to racial or ethnic minorities and birth outcomes.

Methods

We utilized Twitter’s Streaming application programming interface to collect 26,027,740 tweets from June 2015 to December 2017, containing at least one race-related term. Sentiment analysis was performed using support vector machine, a supervised machine learning model. We constructed overall indicators of sentiment toward minorities and sentiment toward race-specific groups. For each year, state-level Twitter-derived sentiment data were merged with birth data for that year. The study participants were women who had singleton births with no congenital abnormalities from 2015 to 2017 and for whom data were available on gestational age (n=9,988,030) or birth weight (n=9,985,402). The main outcomes were low birth weight (birth weight ≤2499 g) and preterm birth (gestational age <37 weeks). We estimated the incidence ratios controlling for individual-level maternal characteristics (sociodemographics, prenatal care, and health behaviors) and state-level demographics, using log binomial regression models.

Results

The accuracy for identifying negative sentiments on comparing the machine learning model to manually labeled tweets was 91%. Mothers living in states in the highest tertile for negative sentiment tweets referencing racial or ethnic minorities had greater incidences of low birth weight (8% greater, 95% CI 4%-13%) and preterm birth (8% greater, 95% CI 0%-14%) compared with mothers living in states in the lowest tertile. More negative tweets referencing minorities were associated with adverse birth outcomes in the total population, including non-Hispanic white people and racial or ethnic minorities. In stratified subgroup analyses, more negative tweets referencing specific racial or ethnic minority groups (black people, Middle Eastern people, and Muslims) were associated with poor birth outcomes for black people and minorities.

Conclusions

A negative social context related to race was associated with poor birth outcomes for racial or ethnic minorities, as well as non-Hispanic white people.

Health disparities in cervical cancer: Prevalence of high-risk HPV and cytologic diagnoses according to race

BACKGROUND

In the United States, the rate of cervical cancer is disproportionally higher in Hispanic and Black women compared with White women. In the current study, the authors compared human papillomavirus (HPV) testing and cytology results among Black and White women over a 24-month period. They then assessed the rates in young women in 2011 compared with 2017 according to race.

METHODS

The authors searched the gynecologic cytology case files for Black and White women treated at Johns Hopkins Hospital across all ages for a period of 24 months (2017-2019) and compared HPV results and cytologic interpretations. They then compared results among Black and White cohorts of young women (aged 21-29 years) in 2011 versus 2017.

RESULTS

A total of 26,302 specimens from January 2017 to January 2019, including 11,676 Black women and 14,626 White women, were reviewed. The most common HPV genotype(s) detected were non-HPV-16 and/or HPV-18 (non-16/18) high-risk HPV (hrHPV) (84% of positive results). Non-16/18 hrHPV was more common in Black women (1309 women; 15%) compared with White women (1075 women; 9%). Non-16/18 hrHPV was more commonly observed in association with atypical squamous cells, cannot rule out high-grade squamous intraepithelial lesion and/or high-grade squamous intraepithelial lesion (ASC-H/HSIL) in HPV-positive Black women compared with White women (P = .007). Black women were found to have higher rates of HPV-positive Papanicolaou results and high-grade lesions, including carcinoma (P < .01). In the 2011 cohort, young Black women were found to have a higher rate of ASC-H/HSIL (P = .003) compared with White women. However, the difference was not noted in the 2017 cohort. There was a decrease in ASC-H/HSIL in 2017 compared with 2011, with a lower incidence of ASC-H/HSIL noted among Black women in 2017.

CONCLUSIONS

Black women appear to have a higher incidence of higher grade lesions, but the difference between Black and White cohorts was not found to be significant in young women in more recent years.

Racial Segregation and Intraventricular Hemorrhage in Preterm Infants

BACKGROUND

Intraventricular hemorrhage (IVH) disproportionately affects black neonates. Other conditions that are more common in black neonates, including low birth weight and preterm delivery, have been linked with residential racial segregation (RRS). In this study, we investigated the association between RRS and IVH.

METHODS

A retrospective cohort of neonates born between 24 and 32 weeks' gestation was constructed by using birth certificates linked to medical records from California, Missouri, and Pennsylvania between 1995 and 2009. Dissimilarity, a measure of RRS indicating the proportion of minorities in the census tract of the mother in comparison to the larger metropolitan area, was linked to patient data, yielding a cohort of 70 775 infants. Propensity score analysis matched infants born to mothers living in high segregation to those living in less segregated areas on the basis of race, sociodemographic factors, and medical comorbidities to compare the risk of developing IVH.

RESULTS

Infants born to mothers in the most segregated quartile had a greater risk of developing IVH compared with those in the lowest quartile (12.9% vs 10.4%; P < .001). In 17 918 pairs matched on propensity scores, the risk of developing IVH was greater in the group exposed to a segregated environment (risk ratio = 1.08, 95% confidence interval: 1.01-1.15). This effect was stronger for black infants alone (risk ratio = 1.16; 95% confidence interval: 1.03-1.30).

CONCLUSIONS

RRS is associated with an increased risk of IVH in preterm neonates, but the effect size varies by race. This association persists after balancing for community factors and birth weight, representing a novel risk factor for IVH.

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.

Factors Influencing Recommended Cancer Screening in Low-Income African American Women in Tennessee

OBJECTIVE

This study examined the factors that predict recommended screening compliance to cervical, breast, and colorectal cancers in low-income African American women. It also examined obstacles to screenings by geographic region and screening status.

METHODS

As a part of the Meharry Community Networks Program (CNP) needs assessment, a 123-item community survey was administered to assess demographic characteristics, health care access and utilization, and screening practices for various cancers in low-income African Americans. For this study, only African American women 40 years and older (n = 308) were selected from the Meharry CNP community survey database.

RESULTS

There were several predictors to recommended screening such as being employed and having health insurance (P < 0.05). Additionally, the obstacles to screening posed a similar level of difficulty for participants from different geographic areas.

DISCUSSION

Sociodemographic differences and obstacles of screening need to be addressed in educational interventions aimed at improving cancer screenings.

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.

Cognitive flexibility and the health of Black college-attending young adults experiencing interpersonal racial discrimination

This study examined the utility of cognitive flexibility for the health of college-attending Black young adults facing chronic interpersonal racial discrimination in a sample of 218 healthy students attending a predominantly White university in the southeastern United States. Path and simple slope analysis indicated that cognitive flexibility moderated the association between racial discrimination and waist circumference but not depressive symptoms. At high cognitive flexibility, more experiences of discrimination were significantly associated with larger waist circumference. Findings suggest that cognitive flexibility may be detrimental for physical health and not of paramount importance for mental health of college-attending Black young adults.

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.

Experiences of Community Doulas Working with Low-Income, African American Mothers

Purpose: The aim of this study was to learn from doulas the components of their services that might best serve low-income, African American (AA) women and to show the significance of doulas in helping these women have healthy, positive, birth experiences.

Methods: Ten doulas were recruited from a local community doula program and through word-of-mouth referrals from participants and completed in-depth interviews. Interviews were transcribed verbatim and analyzed using Atlas.ti software to identify emerging themes. Thematic saturation was achieved in interviews.

Results: Several themes emerged from the interviews including: (1) The influence of similarities of race, culture, and lived experience on doula care; (2) How doulas often provide birthing persons with support and resources beyond birth; and (3) How doulas recognize the institutional biases that exist in the health care system and try to mediate their effect on birthing persons.

Conclusions: These themes highlight how doulas can support birthing persons to mitigate the negative effects of social determinants of health, specifically racism and classism, and highlight potential avenues for doulas to consider when working with birthing persons who have low income and are AA.

The Complexity of Adaptation to Childhood Polyvictimization in Youth and Young Adults: Recommendations for Multidisciplinary Responders

Exposure to violence is pervasive in our society. An abundance of research has demonstrated that individuals who experience polyvictimization (PV)-prolonged or multiple forms of traumatic victimizations-are at heightened risk for continuing to experience repeated victimizations throughout their lifetimes. The current article reviews several overlapping constructs of traumatic victimizations with the ultimate goal of providing a unifying framework for conceptualizing prolonged and multiple victimization (defined in this article as PV) as a precursor to complex post-traumatic biopsychosocial adaptations, revictimization, and in some instances reenactment as a perpetrator (defined as complex trauma [CT]). This model is then applied to three socially disadvantaged victim populations-lesbian, gay, bisexual, transgender, queer, or questioning; commercially sexually exploited individuals; and urban communities of color-who are at heightened risk for PV and for exhibiting complex clinical presentations to demonstrate how the PV-CT framework can destigmatize, reframe, and ultimately reduce health disparities experienced by these populations. Trauma-informed recommendations are provided to aid researchers and multidisciplinary providers working to reduce harm and improve the quality of life for polyvictims.

Twitter-derived measures of sentiment towards minorities (2015-2016) and associations with low birth weight and preterm birth in the United States

INTRODUCTION

The objective of this study was to investigate the association between state-level publicly expressed sentiment towards racial and ethnic minorities and birth outcomes for mothers who gave birth in that state.

METHODS

We utilized Twitter's Streaming Application Programming Interface (API) to collect 1,249,653 tweets containing at least one relevant keyword pertaining to a racial or ethnic minority group. State-level derived sentiment towards racial and ethnic minorities were merged with data on all 2015 U.S. births (N=3.99 million singleton births).

RESULTS

Mothers living in states in the lowest tertile of positive sentiment towards racial/ethnic minorities had greater prevalences of low birth weight (+6%), very low birth weight (+9%), and preterm birth (+10%) compared to mothers living in states in the highest tertile of positive sentiment, controlling for individual-level maternal characteristics and state demographic characteristics. Sentiment towards specific racial/ethnic groups showed a similar pattern. Mothers living in states in the lowest tertile of positive sentiment towards blacks had an 8% greater prevalence of low birth weight and very low birth weight, and a 16% greater prevalence of preterm birth, compared to mothers living in states in the highest tertile. Lower state-level positive sentiment towards Middle Eastern groups was also associated with a 4-13% greater prevalence of adverse birth outcomes. Results from subgroup analyses restricted to racial/ethnic minority mothers did not differ substantially from those seen for the full population of mothers.

CONCLUSIONS

More negative area-level sentiment towards blacks and Middle Eastern groups was related to worse individual birth outcomes, and this is true for the full population and minorities.

Experiences of Racism and Breastfeeding Initiation and Duration Among First-Time Mothers of the Black Women's Health Study

BACKGROUND

Breastfeeding rates are lower for black women in the USA compared with other groups. Breastfeeding and lactation are sensitive time points in the life course, centering breastfeeding as a health equity issue. In the USA, experiences of racism have been linked to poor health outcomes but racism relative to breastfeeding has not been extensively investigated.

AIMS

This study aims to investigate the association between experiences of racism, neighborhood segregation, and nativity with breastfeeding initiation and duration.

METHODS

This is a prospective secondary analysis of the Black Women's Health Study, based on data collected from 1995 through 2005. Daily and institutional (job, housing, police) racism, nativity, and neighborhood segregation in relation to breastfeeding were examined. Odds ratios and 95% confidence intervals were calculated using binomial logistic regression for the initiation outcomes (N = 2705) and multinomial logistic regression for the duration outcomes (N = 2172).

RESULTS

Racism in the job setting was associated with lower odds of breastfeeding duration at 3-5 months. Racism with the police was associated with higher odds of breastfeeding initiation and duration at 3-5 and 6 months. Being born in the USA or having a parent born in the USA predicted lower odds of breastfeeding initiation and duration. Living in a segregated neighborhood (primarily black residents) as a child was associated with decreased breastfeeding initiation and duration relative to growing up in a predominantly white neighborhood.

CONCLUSION

Experiences of institutionalized racism influenced breastfeeding initiation and duration. Structural-level interventions are critical to close the gap of racial inequity in breastfeeding rates in the USA.

The development of the cortisol response to dyadic stressors in Black and White infants

Acute reactivity of the stress hormone cortisol is reflective of early adversity and stress exposure, with some studies finding that the impact of adversity on the stress response differs by race. The objectives of the current study were to characterize cortisol reactivity to two dyadically based stress paradigms across the first year of life, to examine cortisol reactivity within Black and White infants, and to assess the impact of correlates of racial inequity including socioeconomic status, experiences of discrimination, and urban life stressors, as well as the buffering by racial socialization on cortisol patterns. Salivary cortisol reactivity was assessed at 4 months of age during the Still Face paradigm (N = 207) and at 12 months of age across the Strange Situation procedure (N = 129). Infants demonstrated the steepest recovery after the Still Face paradigm and steepest reactivity to the Strange Situation procedure. Race differences in cortisol were not present at 4 months but emerged at 12 months of age, with Black infants having higher cortisol. Experiences of discrimination contributed to cortisol differences within Black infants, suggesting that racial discrimination is already "under the skin" by 1 year of age. These findings suggest that race-related differences in hypothalamic-pituitary-adrenal reactivity are present in infancy, and that the first year of life is a crucial time period during which interventions and prevention efforts for maternal-infant dyads are most likely able to shape hypothalamic-pituitary-adrenal reactivity thereby mitigating health disparities early across the life course.

The association between the end of court-ordered school desegregation and preterm births among Black women

Racial segregation, and in particular school segregation, likely plays an important role in affecting health outcomes. To examine this connection, this paper explores the relationship between the end of court-ordered school desegregation and preterm births among Blacks using birth certificate information between 1992 and 2002 (n = 183,178). The end of court-ordered oversight has important implications for the level of racial segregation in schools: If residential segregation remains high, neighborhood-based student assignment plans would naturally increase school segregation. A rise in school segregation may lead to worse educational, labor, and health outcomes among Blacks. Using multiple difference-in-differences framework that exploits variation in exposure to schools that declared unitary status, it finds that school districts’ release from court oversight is associated with a 0.8 percentage point increase in preterm births among Black mothers. This paper contributes to literature that finds that the end of court-ordered school desegregation in the 1990s have negative implications for Blacks. More research should be conducted to understand the causal relationship between school segregation and infant health.

Equitable health: let's stick together as we address global discrimination, prejudice and stigma

Tackling discrimination permanently in healthcare is not insurmountable. It is achievable. Discrimination is costly in lives, in healthcare delivery and waste, in human capital, in financial resource and even in healthcare improvement initiatives that do not adequately account for its impact. Healthcare must understand the underlying inequalities each faces from the start and tailor care toward equal health outcomes. Solutions have been offered and should be funded and evaluated. Additionally, a global plan to address discrimination and bias in healthcare must be consistent, accountable and be shaped around standardized tools and measures. The idea that an individual is better or more important than another has no place in today’s world, particularly in health. Therefore, it is critical that each is provided his or her individual needs to achieve best outcomes. It is critical for healthcare to advance health equity. Global healthcare must do its part to be a team leader on this issue.

Discrimination Fully Mediates the Effects of Incarceration History on Depressive Symptoms and Psychological Distress Among African American Men

AIM

Using a nationally representative sample of African American men, this study investigated the associations between lifetime history of incarceration, discrimination, and mental health (e.g., depressive symptoms and psychological distress). We hypothesized that discrimination would fully mediate the association between incarceration history and mental health outcomes among African American men.

METHODS

Using a cross-sectional design, our analysis included 1271 African American men who participated in the National Survey of American Life (NSAL), 2001-2003. Incarceration history was the main independent variable. Depressive symptoms and psychological distress were the dependent variables. Everyday discrimination was the mediator. Age, education, and income were covariates. Structural equation models (SEMs) were used for data analysis.

RESULTS

Among African American men, incarceration history was positively associated with perceived discrimination, depressive symptoms, and psychological distress. Everyday discrimination fully mediated the associations between incarceration history and both depressive symptoms and psychological distress.

CONCLUSION

Discrimination may play an important role in the mental health problems of African American men with a history of incarceration. These findings have public policy implications as well as clinical implications for mental health promotion of African American men. Policies that reduce preventable incarceration or at least reduce subsequent discrimination for those who have been incarcerated may enhance mental health of previously incarcerated African American men.

Cardiovascular Health in African Americans: A Scientific Statement From the American Heart Association

BACKGROUND AND PURPOSE

Population-wide reductions in cardiovascular disease incidence and mortality have not been shared equally by African Americans. The burden of cardiovascular disease in the African American community remains high and is a primary cause of disparities in life expectancy between African Americans and whites. The objectives of the present scientific statement are to describe cardiovascular health in African Americans and to highlight unique considerations for disease prevention and management.

METHOD

The primary sources of information were identified with PubMed/Medline and online sources from the Centers for Disease Control and Prevention.

RESULTS

The higher prevalence of traditional cardiovascular risk factors (eg, hypertension, diabetes mellitus, obesity, and atherosclerotic cardiovascular risk) underlies the relatively earlier age of onset of cardiovascular diseases among African Americans. Hypertension in particular is highly prevalent among African Americans and contributes directly to the notable disparities in stroke, heart failure, and peripheral artery disease among African Americans. Despite the availability of effective pharmacotherapies and indications for some tailored pharmacotherapies for African Americans (eg, heart failure medications), disease management is less effective among African Americans, yielding higher mortality. Explanations for these persistent disparities in cardiovascular disease are multifactorial and span from the individual level to the social environment.

CONCLUSIONS

The strategies needed to promote equity in the cardiovascular health of African Americans require input from a broad set of stakeholders, including clinicians and researchers from across multiple disciplines.

Access to and Satisfaction with Prenatal Care Among Pregnant Women with Physical Disabilities: Findings from a National Survey

BACKGROUND

Previous qualitative studies suggest that women with physical disabilities face disability-specific barriers and challenges related to prenatal care accessibility and quality. This study aims to examine the pregnancy and prenatal care experiences and needs of U.S. mothers with physical disabilities and their perceptions of their interactions with their maternity care clinicians.

MATERIALS AND METHODS

We conducted the first survey of maternity care access and experiences of women with physical disabilities from 37 states. The survey was disseminated in partnership with disability community agencies and via social media and targeted U.S. women with a range of physical disabilities who had given birth in the past 10 years. The survey included questions regarding prenatal care quality and childbirth and labor experiences.

RESULTS

A total of 126 women with various physical disability types from 37 states completed the survey. Almost half of the respondents (53.2%) reported that their physical disability was a big factor in their selection of a maternity care provider and 40.3% of women reported that their prenatal care provider knew little or nothing about the impact of their physical disability on their pregnancy. Controlling for maternal demographic characteristics and use of mobility equipment, women who reported that their prenatal care provider lacked knowledge of disability and those who felt they were not given adequate information were more likely to report unmet needs for prenatal care.

CONCLUSIONS

The findings from this study suggest the need for training and education for clinicians regarding the prenatal care needs of women with physical disabilities.

Associations between racial discrimination, smoking during pregnancy and low birthweight among Roma

Background

Racial discrimination may increase the risk of low birthweight (LBW), but has not been studied among Roma, the largest minority population in Europe. Moreover, few studies test both institutional and interpersonal forms of racial discrimination on health. Our objective was to examine associations between institutional and interpersonal racial discrimination with LBW, and to test potential mediation by smoking during pregnancy. In 2012-2013, Romani women interviewers surveyed 410 Romani women in Serbia and Macedonia. We measured institutional discrimination (neighborhood segregation, legal status of housing and neighborhood socioeconomic status), interpersonal discrimination [Everyday Discrimination Scale (EDS)], birthweight and smoking by self-report or interviewer report. We estimated relative risks for discrimination on LBW and separately on smoking during pregnancy using log-binomial regression, adjusting for age, parity, years at residence and wealth. The indirect effect of high EDS via smoking on LBW was estimated using inverse odds weighting mediation. Living in a low SES neighborhood showed a 2-fold risk of LBW [adjusted risk ratio (aRR) = 2.4, 95% CI = 1.2, 5.0]; aRRs for segregation and illegal housing were weaker (aRR = 1.8, 95% CI = 0.7, 4.3; aRR = 1.3, 95% CI = 0.6, 2.6, respectively). Institutional measures were not associated with smoking. High EDS was associated with LBW (aRR = 2.4, 95% CI = 1.1, 5.2) and smoking during pregnancy (aRR = 1.4, 95% CI = 1.1, 1.8); the indirect effect of EDS on LBW via smoking was not significant. Interpersonal discrimination and living in a low SES neighborhood were associated with LBW among Roma. Interventions to improve Romani health may benefit from a human rights approach.

Anticipating anonymity in screening program databases

In this paper, we propose a technique for improving anonymity in screening program databases to increase the privacy for the participants in these programs. The data generated by the invitation process (screening centre, appointment date) is often made available to researchers for medical research and for evaluation and improvement of the screening program. This information, combined with other personal quasi-identifiers such as the ZIP code, gender or age, can pose a risk of disclosing the identity of the individuals participating in the program, and eventually their test results. We present two algorithms that produce a set of screening appointments that aim to increase anonymity of the resulting dataset. The first one, based on the constraint programming paradigm, defines the optimal appointments, while the second one is a suboptimal heuristic algorithm that can be used with real size datasets. The level of anonymity is measured using the new concept of generalized k-anonymity, which allows us to show the utility of the proposal by means of experiments, both using random data and data based on screening invitations from the Norwegian Cancer Registry.

Perceived Weight Discrimination and 10-Year Risk of Allostatic Load Among US Adults

BACKGROUND

Discrimination promotes multisystem physiological dysregulation termed allostatic load, which predicts morbidity and mortality. It remains unclear whether weight-related discrimination influences allostatic load.

PURPOSE

The aim of this study was to prospectively examine 10-year associations between weight discrimination, allostatic load, and its components among adults 25-75 years in the Midlife Development in the US Biomarker Substudy.

METHODS

Participants with information on weight discrimination were analyzed (n=986). At both timepoints, participants self-reported the frequency of perceived weight discrimination across nine scenarios as "never/rarely" (scored as 0), "sometimes" (1), or "often" (2). The two scores were averaged and then dichotomized as "experienced" versus "not experienced" discrimination. High allostatic load was defined as having ≥3 out of 7 dysregulated systems (cardiovascular, sympathetic/parasympathetic nervous systems, hypothalamic pituitary axis, inflammatory, lipid/metabolic, and glucose metabolism), which collectively included 24 biomarkers. Relative risks (RR) were estimated from multivariate models adjusted for sociodemographic and health characteristics, other forms of discrimination, and BMI.

RESULTS

Over 41% of the sample had obesity, and 6% reported weight discrimination at follow-up. In multivariable-adjusted analyses, individuals who experienced (versus did not experience) weight discrimination had twice the risk of high allostatic load (RR, 2.07; 95 % CI, 1.21; 3.55 for baseline discrimination; 2.16, 95 % CI, 1.39; 3.36 for long-term discrimination). Weight discrimination was associated with lipid/metabolic dysregulation (1.56; 95 % CI 1.02, 2.40), glucose metabolism (1.99; 95 % CI 1.34, 2.95), and inflammation (1.76; 95 % CI 1.22, 2.54), but no other systems.

CONCLUSIONS

Perceived weight discrimination doubles the 10-year risk of high allostatic load. Eliminating weight stigma may reduce physiological dysregulation, improving obesity-related morbidity and mortality.

Does Lack of "Genetic-Relative Family Health History" Represent a Potentially Avoidable Health Disparity for Adoptees?

Many adoptees face a number of challenges relating to separation from biological parents during the adoption process, including issues concerning identity, intimacy, attachment, and trust, as well as (for older adopted children) language and other cultural challenges. One common health challenge faced by adoptees involves lack of access to genetic-relative family health history (GRFHx). Lack of GRFHx represents a disadvantage due to a reduced capacity to identify diseases and recommend appropriate screening for conditions for which the adopted person may be at increased risk. In this article, we draw out common features of traditionally understood "health disparities" in order to identify analogous features in the context of adoptees' lack of GRFHx.

New spatially continuous indices of redlining and racial bias in mortgage lending: links to survival after breast cancer diagnosis and implications for health disparities research

Racial health disparities continue to be a serious problem in the United States and have been linked to contextual factors, including racial segregation. In some cases, including breast cancer survival, racial disparities appear to be worsening. Using the Home Mortgage Disclosure Act (HMDA) database, we extend current spatial analysis methodology to derive new, spatially continuous indices of (1) racial bias in mortgage lending and (2) redlining. We then examine spatial patterns of these indices and the association between these new measures and breast cancer survival among Black/African American women in the Milwaukee, Wisconsin metropolitan area. These new measures can be used to examine relationships between mortgage discrimination and patterns of disease throughout the United States.

Racial Discrimination and HIV-related Risk Behaviors in Southeast Louisiana

OBJECTIVES

We examined the relationship between cumulative experiences of racial discrimination and HIV-related risk taking, and whether these relationships are mediated through alcohol use among African Americans in semi-rural southeast Louisiana.

METHODS

Participants (N = 214) reported on experiences of discrimination, HIV sexual risk-taking, history of sexually transmitted infection (STI), and health behaviors including alcohol use in the previous 90 days. Experiences of discrimination (scaled both by frequency of occurrence and situational counts) as a predictor of a sexual risk composite score as well as a history of STI was assessed using multivariate linear and logistic regression, respectively, including tests for mediation by alcohol use.

RESULTS

Discrimination was common in this cohort, with respondents confirming their experience on average 7 of the 9 potential situations and on more than 34 separate occasions. After adjustment, discrimination was significantly associated with increasing sexual risk-taking and lifetime history of STI when measured either by frequency of occurrence or number of situations, although there was no evidence that these relationships were mediated through alcohol use.

CONCLUSIONS

Cumulative experiences of discrimination may play a significant role in sexual risk behavior and consequently increase vulnerability to HIV and other STIs.
