Area racism and birth outcomes among Blacks in the United States

Long-term ambient sulfur dioxide exposure during gestation and preterm birth in North Carolina, 2003-2015

BACKGROUND

Coal-fired power plants are major contributors of ambient sulfur dioxide (SO2) air pollution. Epidemiological literature suggests an adverse association between SO2 exposure during gestation and preterm birth (PTB; <37 weeks completed gestation). PTB is strongly associated with infant mortality and increased risk for later life morbidities.

OBJECTIVE

We investigated associations between SO2 and PTB in North Carolina and evaluated whether the associations were modified by race/ethnicity.

METHODS

We assembled a retrospective, administrative cohort of singleton births in North Carolina from 2003-2015. We used US EPA EQUATES data to assign long-term SO2 gestational exposures to eligible births for the entire pregnancy and by trimester. We used multivariable generalized linear regression to estimate risk differences (RD (95%CI)) per 1-ppb increase in SO2, adjusted for gestational parent education, Medicaid status, marital status, and season of conception. Multi-pollutant models were additionally adjusted for other criteria air co-pollutants (O3, PM2.5, NO2).

RESULTS

The median SO2 (24-hour average) across exposure windows was ~1.5 (IQR: 1.8) ppb. The overall baseline risk for PTB was 8,756 per 100,000 live births. When stratified by race/ethnicity, the baseline risk for PTB was 12215, 7824, and 7187 per 100,000 live births among non-Hispanic Black, non-Hispanic white, and Hispanic births, respectively. RDs per 1-ppb increase in SO2 averaged across the entire pregnancy were 317.0 (95%CI: 279.4, 354.5) and 568.2 (95%CI: 500.3, 636.1) per 100,000 live births for single- and multi-pollutant models, respectively. For the PTB multi-pollutant models, we observed similar RDs for non-Hispanic Black participants (669.6 [95%CI: 573.9, 765.2]) and non-Hispanic white participants (635.4 [95%CI: 557.2, 713.6]) with smaller RDs for Hispanic participants (336.8 [95%CI: 241.3, 432.2]).

SIGNIFICANCE

The results for our adjusted single- and multi-pollutant models showed adverse associations between SO2 and PTB, with some evidence of effect measure modification by race/ethnicity within subcategories of PTB.

Public drinking water contaminant estimates for birth cohorts in the Environmental Influences on Child Health Outcomes (ECHO) Cohort

BACKGROUND

The United States Environmental Protection Agency (USEPA) regulates over 80 contaminants in community water systems (CWS), including those relevant to infant health outcomes. Multi-cohort analyses of the association between measured prenatal public water contaminant concentrations and infant health outcomes are sparse in the US.

OBJECTIVE

Our objectives were to (1) develop Zip Code Tabulation Area (ZCTA)-level CWS contaminant concentrations for participants in the Environmental Influences on Child Health Outcomes (ECHO) Cohort and (2) evaluate regional, seasonal, and sociodemographic inequities in contaminant concentrations at the ZCTA-level. The ECHO Cohort harmonizes data from over 69 extant pregnancy and pediatric cohorts across the US.

METHODS

We used CWS estimates derived from the USEPA's Six-Year Review 3 (2006-2011) to develop population-weighted, average concentrations for 10 contaminants across 7640 ZCTAs relevant to the ECHO Cohort. We evaluated contaminant distributions, exceedances of regulatory thresholds, and geometric mean ratios (with corresponding percent changes) associated with ZCTA sociodemographic characteristics via spatial lag linear regression models.

RESULTS

We observed significant regional variability in contaminant concentrations across the US. ZCTAs were most likely to exceed the maximum contaminant level for arsenic (n = 100, 1.4%) and the health-protective threshold for total trihalomethanes (n = 3584, 64.0%). A 10% higher proportion of residents who were American Indian/Alaskan Native and Hispanic/Latino was associated with higher arsenic (11%, 95% CI: 7%, 15%; and 2%, 95% CI: 0%, 3%, respectively) and uranium (15%, 95% CI: 10%, 21%; and 9%, 95% CI: 6%, 12%, respectively) concentrations.

IMPACT

Nationwide epidemiologic analyses evaluating the association between US community water system contaminant concentration estimates and associated adverse birth outcomes in cohort studies are sparse because public water contaminant concentration estimates that can be readily linked to participant addresses are not available. We developed Zip Code Tabulation Area (ZCTA)-level CWS contaminant concentrations that can be linked to participants in the Environmental Influences on Child Health Outcomes (ECHO) Cohort and evaluated regional, seasonal, and sociodemographic inequities in contaminant concentrations for these ZCTAs. Future epidemiologic studies can leverage these CWS exposure estimates in the ECHO Cohort to evaluate associations with relevant infant outcomes.

Racialization processes and depressive symptoms among pregnant Mexican-origin immigrant women

This study examines how racialization processes (conceptualized as multilevel and dynamic processes) shape prenatal mental health by testing the association of discrimination and the John Henryism hypothesis on depressive symptoms for pregnant Mexican-origin immigrant women. We analyzed baseline data (n = 218) from a healthy lifestyle intervention for pregnant Latinas in Detroit, Michigan. Using separate multiple linear regression models, we examined the independent and joint associations of discrimination and John Henryism with depressive symptoms and effect modification by socioeconomic position. Discrimination was positively associated with depressive symptoms (β = 2.84; p < .001) when adjusting for covariates. This association did not vary by socioeconomic position. Women primarily attributed discrimination to language use, racial background, and nativity. We did not find support for the John Henryism hypothesis, meaning that the hypothesized association between John Henryism and depressive symptoms did not vary by socioeconomic position. Examinations of joint associations of discrimination and John Henryism on depressive symptoms indicate a positive association between discrimination and depressive symptoms (β = 2.81; p < .001) and no association of John Henryism and depressive symptoms (β = -0.83; p > .05). Results suggest complex pathways by which racialization processes affect health and highlight the importance of considering experiences of race, class, and gender within racialization processes.

Black Pregnancy-Related Mortality in the United States

The maternal mortality rate for non-Hispanic Black birthing people is 69.9 deaths per 100,000 live births compared with 26.6 deaths per 100,000 live births for non-Hispanic White birthing people. Black pregnancy-related mortality has been underrepresented in research and the media; however, there is growing literature on the role of racism in health disparities. Those who provide care to Black patients should increase their understanding of racism's impact and take steps to center the experiences and needs of Black birthing people.

Structural Racism and Health Stratification: Connecting Theory to Measurement

Less than 1% of studies on racialized health inequities have empirically examined their root cause: structural racism. Moreover, there has been a disconnect between the conceptualization and measurement of structural racism. This study advances the field by (1) distilling central tenets of theories of structural racism to inform measurement approaches, (2) conceptualizing U.S. states as racializing institutional actors shaping health, (3) developing a novel latent measure of structural racism in states, (4) using multilevel models to quantify the association between structural racism and five individual-level health outcomes among respondents from the Health and Retirement Study (N = 9,020) and the Behavioral Risk Factor Surveillance System (N = 308,029), and (5) making our measure of structural racism publicly available to catalyze research. Results show that structural racism is consistently associated with worse health for Black people but not White people. We conclude by highlighting this study's contributions (theoretical, methodological, and substantive) and important avenues for future research on the topic.

A Decade of Tweets: Visualizing Racial Sentiments Towards Minoritized Groups in the United States Between 2011 and 2021

BACKGROUND

Research has demonstrated the negative impact of racism on health, yet the measurement of racial sentiment remains challenging. This article provides practical guidance on using social media data for measuring public sentiment.

METHODS

We describe the main steps of such research, including data collection, data cleaning, binary sentiment analysis, and visualization of findings. We randomly sampled 55,844,310 publicly available tweets from 1 January 2011 to 31 December 2021 using Twitter's Application Programming Interface. We restricted analyses to US tweets in English using one or more 90 race-related keywords. We used a Support Vector Machine, a supervised machine learning model, for sentiment analysis.

RESULTS

The proportion of tweets referencing racially minoritized groups that were negative increased at the county, state, and national levels, with a 16.5% increase at the national level from 2011 to 2021. Tweets referencing Black and Middle Eastern people consistently had the highest proportion of negative sentiment compared with all other groups. Stratifying temporal trends by racial and ethnic groups revealed unique patterns reflecting historical events specific to each group, such as the killing of George Floyd regarding sentiment of posts referencing Black people, discussions of the border crisis near the 2018 midterm elections and anti-Latinx sentiment, and the emergence of COVID-19 and anti-Asian sentiment.

CONCLUSIONS

This study demonstrates the utility of social media data as a quantitative means to measure racial sentiment over time and place. This approach can be extended to a range of public health topics to investigate how changes in social and cultural norms impact behaviors and policy.A supplemental digital video is available at http://links.lww.com/EDE/C91.

A research agenda for understanding how social inequality is linked to brain structure and function

Consistent evidence documents powerful effects of social inequality on health, well-being and academic achievement. Yet research on whether social inequality may also be linked to brain structure and function has, until recently, been rare. Here we describe three methodological approaches that can be used to study this question-single site, single study; multi-site, single study; and spatial meta-analysis. We review empirical work that, using these approaches, has observed associations between neural outcomes and structural measures of social inequality-including structural stigma, community-level prejudice, gender inequality, neighbourhood disadvantage and the generosity of the social safety net for low-income families. We evaluate the relative strengths and limitations of these approaches, discuss ethical considerations and outline directions for future research. In doing so, we advocate for a paradigm shift in cognitive neuroscience that explicitly incorporates upstream structural and contextual factors, which we argue holds promise for uncovering the neural correlates of social inequality.

Dual pandemics? Assessing associations between area racism, COVID-19 case rates, and mental health among U.S. adults

Mental health worsened during the COVID-19 pandemic, especially among racially minoritized adults. Population-level racial attitudes, or area racism, may be associated with mental health, particularly during this historical moment, but this possibility has not been tested in prior research. In the present study, we use nationally representative data from the Household Pulse Survey (April-October 2020) to document associations between area racism and depression/anxiety in the United States among non-Hispanic Black, non-Hispanic Asian, Hispanic, non-Hispanic White, and other racial/ethnic minority adults. We further consider the national COVID-19 case rate to examine an additional macro-level stressor. Findings indicate that area racism was positively associated with depression and/or anxiety for Black, Hispanic, White, and other racial/ethnic minority adults. Moreover, COVID-19 cases posed an additional, independent mental health threat for most groups. This study points to area racism as a macro-level stressor and an antecedent of mental health for racially diverse groups of Americans.

Structural Racism and Adverse Pregnancy Outcomes Through the Lens of the Maternal Microbiome

Microbiome science offers a glimpse into personalized medicine by characterizing health and disease states according to an individual's microbial signatures. Without a critical examination of the use of race as a variable, microbiome studies may be susceptible to the same pitfalls as other areas of science grounded in racist biology. We will examine the use of race as a biological variable in pregnancy-related microbiome research. Emerging data from studies that investigate the intestinal microbiome in pregnancy suggest strong influence of a poor diet on adverse pregnancy outcomes. Differences in the vaginal microbiome implicated in adverse pregnancy outcomes are frequently attributed to race. We review evidence that links systemic racism to pregnancy health outcome differences with a focus on the vaginal and intestinal microbiomes as well as diet. We also review how structural racism ultimately contributes to inequitable access to healthy food and higher risk environmental exposures among pregnant people of lower socioeconomic status and exacerbates common pregnancy comorbidities.

Interpersonal Discrimination, Neighborhood Inequities, and Children's Body Mass Index: A Descriptive, Cross-Sectional Analysis

Psychosocial stressors have been implicated in childhood obesity, but the role of racism-related stressors is less clear. This study explored associations between neighborhood inequities, discrimination/harassment, and child body mass index (BMI). Parents of children aged 5-9 years from diverse racial/ethnic backgrounds (n = 1307), completed surveys of their child's exposure to discrimination/harassment. Census tract data derived from addresses were used to construct an index of concentration at the extremes, a measure of neighborhood social polarization. Child's height and weight were obtained from medical records. Multiple regression and hierarchical models examined child's BMI and racism at the individual and census tract levels. Children residing in the most Black-homogenous census tracts had 8.2 percentage units higher BMI percentile (95% confidence interval, 1.5-14.9) compared with white-homogenous tracts (P = .03). Household income and home values were lower, poverty rates higher, and single parent households more common among Black-homogeneous census tracts. Almost 30% of children experienced discrimination/harassment in the past year, which was associated with a 5.28-unit higher BMI percentile (95% confidence interval, 1.72-8.84; P = .004). Discrimination and racial/economic segregation were correlated with higher child BMI. Longitudinal studies are needed to understand whether these factors may be related to weight gain trajectories and future health.

The Water Surrounding the Iceberg: Cultural Racism and Health Inequities

Policy Points Cultural racism-or the widespread values that privilege and protect Whiteness and White social and economic power-permeates all levels of society, uplifts other dimensions of racism, and contributes to health inequities. Overt forms of racism, such as racial hate crimes, represent only the "tip of the iceberg," whereas structural and institutional racism represent its base. This paper advances cultural racism as the "water surrounding the iceberg," allowing it to float while obscuring its base. Considering the fundamental role of cultural racism is needed to advance health equity.

CONTEXT

Cultural racism is a pervasive social toxin that surrounds all other dimensions of racism to produce and maintain racial health inequities. Yet, cultural racism has received relatively little attention in the public health literature. The purpose of this paper is to 1) provide public health researchers and policymakers with a clearer understanding of what cultural racism is, 2) provide an understanding of how it operates in conjunction with the other dimensions of racism to produce health inequities, and 3) offer directions for future research and interventions on cultural racism.

METHODS

We conducted a nonsystematic, multidisciplinary review of theory and empirical evidence that conceptualizes, measures, and documents the consequences of cultural racism for social and health inequities.

FINDINGS

Cultural racism can be defined as a culture of White supremacy, which values, protects, and normalizes Whiteness and White social and economic power. This ideological system operates at the level of our shared social consciousness and is expressed in the language, symbols, and media representations of dominant society. Cultural racism surrounds and bolsters structural, institutional, personally mediated, and internalized racism, undermining health through material, cognitive/affective, biologic, and behavioral mechanisms across the life course.

CONCLUSIONS

More time, research, and funding is needed to advance measurement, elucidate mechanisms, and develop evidence-based policy interventions to reduce cultural racism and promote health equity.

"Speak Up!" Investigating U.S. professional sports teams' #BlackLivesMatter statements

George Floyd's death caused by police brutality fueled a wave of the Black Lives Matter (BLM) movement both nationally and globally. Almost every professional sports team in the United States released a statement pertaining to racial inequality and social injustice. The current study investigated the content and word counts of the BLM statements posted on Twitter by all teams across the four major men's professional sports leagues: Major League Baseball (MLB), National Basketball Association (NBA), National Football League (NFL), and National Hockey League (NHL). Based on a series of text analyses, we found differences in both the content and word counts of statements put forth by each league. Notably, compared to teams in other leagues, NFL teams avoided negative sentiment words (e.g., by not using words like "racism") and utilized more action-oriented terms like "support", "listen", and "conversation" in their statements. Practical implications and future directions for research are discussed.

Disparities by race/ethnicity in unplanned cesarean birth among healthy nulliparas: a secondary analysis of the nuMoM2b dataset

BACKGROUND

Racial disparities exist in maternal morbidity and mortality, with most of these events occurring in healthy pregnant people. A known driver of these outcomes is unplanned cesarean birth. Less understood is to what extent maternal presenting race/ethnicity is associated with unplanned cesarean birth in healthy laboring people, and if there are differences by race/ethnicity in intrapartum decision-making prior to cesarean birth.

METHODS

This secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b) dataset involved nulliparas with no significant health complications at pregnancy onset who had a trial of labor at ≥ 37 weeks with a singleton, non-anomalous fetus in cephalic presentation (N = 5,095). Logistic regression models were used to examine associations between participant-identified presenting race/ethnicity and unplanned cesarean birth. Participant-identified presenting race/ethnicity was used to capture the influence of racism on participant's healthcare experiences.

RESULTS

Unplanned cesarean birth occurred in 19.6% of labors. Rates were significantly higher among Black- (24.1%) and Hispanic- (24.7%) compared to white-presenting participants (17.4%). In adjusted models, white participants had 0.57 (97.5% CI [0.45-0.73], p < 0.001) lower odds of unplanned cesarean birth compared to Black-presenting participants, while Hispanic-presenting had similar odds as Black-presenting people. The primary indication for cesarean birth among Black- and Hispanic- compared to white-presenting people was non-reassuring fetal heart rate in the setting of spontaneous labor onset.

CONCLUSIONS

Among healthy nulliparas with a trial of labor, white-presenting compared to Black or Hispanic-presenting race/ethnicity was associated with decreased odds of unplanned cesarean birth, even after adjustment for pertinent clinical factors. Future research and interventions should consider how healthcare providers' perception of maternal race/ethnicity may bias care decisions, leading to increased use of surgical birth in low-risk laboring people and racial disparities in birth outcomes.

Examining Twitter-Derived Negative Racial Sentiment as Indicators of Cultural Racism: Observational Associations With Preterm Birth and Low Birth Weight Among a Multiracial Sample of Mothers, 2011-2021

BACKGROUND

Large racial and ethnic disparities in adverse birth outcomes persist. Increasing evidence points to the potential role of racism in creating and perpetuating these disparities. Valid measures of area-level racial attitudes and bias remain elusive, but capture an important and underexplored form of racism that may help explain these disparities. Cultural values and attitudes expressed through social media reflect and shape public norms and subsequent behaviors. Few studies have quantified attitudes toward different racial groups using social media with the aim of examining associations with birth outcomes.

OBJECTIVE

We used Twitter data to measure state-level racial sentiments and investigate associations with preterm birth (PTB) and low birth weight (LBW) in a multiracial or ethnic sample of mothers in the United States.

METHODS

A random 1% sample of publicly available tweets from January 1, 2011, to December 31, 2021, was collected using Twitter's Academic Application Programming Interface (N=56,400,097). Analyses were on English-language tweets from the United States that used one or more race-related keywords. We assessed the sentiment of each tweet using support vector machine, a supervised machine learning model. We used 5-fold cross-validation to assess model performance and achieved high accuracy for negative sentiment classification (91%) and a high F1 score (84%). For each year, the state-level racial sentiment was merged with birth data during that year (~3 million births per year). We estimated incidence ratios for LBW and PTB using log binomial regression models, among all mothers, Black mothers, racially minoritized mothers (Asian, Black, or Latina mothers), and White mothers. Models were controlled for individual-level maternal characteristics and state-level demographics.

RESULTS

Mothers living in states in the highest tertile of negative racial sentiment for tweets referencing racial and ethnic minoritized groups had an 8% higher (95% CI 3%-13%) incidence of LBW and 5% higher (95% CI 0%-11%) incidence of PTB compared to mothers living in the lowest tertile. Negative racial sentiment referencing racially minoritized groups was associated with adverse birth outcomes in the total population, among minoritized mothers, and White mothers. Black mothers living in states in the highest tertile of negative Black sentiment had 6% (95% CI 1%-11%) and 7% (95% CI 2%-13%) higher incidence of LBW and PTB, respectively, compared to mothers living in the lowest tertile. Negative Latinx sentiment was associated with a 6% (95% CI 1%-11%) and 3% (95% CI 0%-6%) higher incidence of LBW and PTB among Latina mothers, respectively.

CONCLUSIONS

Twitter-derived negative state-level racial sentiment toward racially minoritized groups was associated with a higher risk of adverse birth outcomes among the total population and racially minoritized groups. Policies and supports establishing an inclusive environment accepting of all races and cultures may decrease the overall risk of adverse birth outcomes and reduce racial birth outcome disparities.

Sulfur dioxide reduction at coal-fired power plants in North Carolina and associations with preterm birth among surrounding residents

Coal-fired power plants (CFPP) are major contributors of air pollution, including the majority of anthropogenic sulfur dioxide (SO2) emissions, which have been associated with preterm birth (PTB). To address a 2002 North Carolina (NC) policy, 14 of the largest NC CFPPs either installed desulfurization equipment (scrubbers) or retired coal units, resulting in substantial reductions of SO2 air emissions. We investigated whether SO2 air emission reduction strategies at CFPPs in NC were associated with changes in prevalence of PTB in nearby communities.

Methods

We used US EPA Air Markets Program Data to track SO2 emissions and determine the implementation dates of intervention at CFPPs and geocoded 2003-2015 NC singleton live births. We conducted a difference-in-difference analysis to estimate change in PTB associated with change in SO2 reduction strategies for populations living 0-<4 and 4-<10 miles from CFPPs pre- and postintervention, with a comparison of those living 10-<15 miles from CFPPs.

Results

With the spatial-temporal exposure restrictions applied, 42,231 and 41,218 births were within 15 miles of CFPP-scrubbers and CFPP-retired groups, respectively. For residents within 4-<10 miles from a CFPP, we estimated that the absolute prevalence of PTB decreased by -1.5% [95% confidence interval (CI): -2.6, -0.4] associated with scrubber installation and -0.5% (95% CI: -1.6, 0.6) associated with the retirement of coal units at CFPPs. Our findings were imprecise and generally null-to-positive among those living within 0-<4 miles regardless of the intervention type.

Conclusions

Results suggest a reduction of PTB among residents 4-<10 miles of the CFPPs that installed scrubbers.

The Future of Social Determinants of Health: Looking Upstream to Structural Drivers

Policy Points Policies that redress oppressive social, economic, and political conditions are essential for improving population health and achieving health equity. Efforts to remedy structural oppression and its deleterious effects should account for its multilevel, multifaceted, interconnected, systemic, and intersectional nature. The U.S. Department of Health and Human Services should facilitate the creation and maintenance of a national publicly available, user-friendly data infrastructure on contextual measures of structural oppression. Publicly funded research on social determinants of health should be mandated to (a) analyze health inequities in relation to relevant data on structural conditions and (b) deposit the data in the publicly available data repository.

Structural racism and homophobia evaluated through social media sentiment combined with activity spaces and associations with mental health among young sexual minority men

BACKGROUND

Research suggests that structural racism and homophobia are associated with mental well-being. However, structural discrimination measures which are relevant to lived experiences and that evade self-report biases are needed. Social media and global-positioning systems (GPS) offer opportunity to measure place-based negative racial sentiment linked to relevant locations via precise geo-coding of activity spaces. This is vital for young sexual minority men (YSMM) of color who may experience both racial and sexual minority discrimination and subsequently poorer mental well-being.

METHODS

P18 Neighborhood Study (n = 147) data were used. Measures of place-based negative racial and sexual-orientation sentiment were created using geo-located social media as a proxy for racial climate via socially-meaningfully-defined places. Exposure to place-based negative sentiment was computed as an average of discrimination by places frequented using activity space measures per person. Outcomes were number of days of reported poor mental health in last 30 days. Zero-inflated Poisson regression analyses were used to assess influence of and type of relationship between place-based negative racial or sexual-orientation sentiment exposure and mental well-being, including the moderating effect of race/ethnicity.

RESULTS

We found evidence for a non-linear relationship between place-based negative racial sentiment and mental well-being among our racially and ethnically diverse sample of YSMM (p < .05), and significant differences in the relationship for different race/ethnicity groups (p < .05). The most pronounced differences were detected between Black and White non-Hispanic vs. Hispanic sexual minority men. At two standard deviations above the overall mean of negative racial sentiment exposure based on activity spaces, Black and White YSMM reported significantly more poor mental health days in comparison to Hispanic YSMM.

CONCLUSIONS

Effects of discrimination can vary by race/ethnicity and discrimination type. Experiencing place-based negative racial sentiment may have implications for mental well-being among YSMM regardless of race/ethnicity, which should be explored in future research including with larger samples sizes.

Exposure to anti-Black Lives Matter movement and obesity of the Black population

RATIONALE

Black Lives Matter (BLM) is a social movement against systematic injustice and police violence toward Black people whose goal is to ensure their safety and the expression of their culture. As BLM gained momentum, counter-movements emerged, such as All Lives Matter (ALM), White Lives Matter (WLM), and Blue Lives Matter (BlueLM). Because they undermine support for Black people's safety and culture, exposure to stances against BLM can be a race-related stressor. Although the perception of racial discrimination has been associated with negative health outcomes in Black people, it is not clear whether exposure to negative stances on a race-related social issue is associated with worse health outcomes.

OBJECTIVE

We investigated whether living in areas of the United States with a high prevalence of negative stances on BLM is associated with worse health outcomes, such as higher body mass index (BMI) and prevalence of obesity.

METHODS

We scraped geo-coded tweets (N = 51,020) that contained #BLM, #ALM, #WLM, and #BlueLM from 2014 to 2016. We determined the stances of the tweets on BLM using machine learning algorithms and aggregated stances at the metropolitan or micropolitan statistical area (MMSA) levels. Participants' BMI and obesity status were derived from the 2017 BRFSS SMART data in 76 MMSAs, as compiled by the Centers for Disease Control and Prevention (N = 20,530).

RESULTS

After controlling for individual- and regional-level covariates, regional measures of racism and police brutality rate, and baseline BMI in 2014 aggregated on MMSA level, Black people had a higher BMI and prevalence of obesity in areas that showed higher negative stances on BLM. Stances against BLM were positively associated with implicit racism against Black people and can be an acute race-related stressor associated with negative downstream health outcomes.

CONCLUSION

Negative societal sentiments around race-related issues may be detrimental to the health outcomes of minority populations.

Measures of Racism and Discrimination in Preterm Birth Studies

OBJECTIVE

Preterm birth (any birth at less than 37 weeks of gestation) disproportionally affects Black birthing people and is associated with adverse perinatal and fetal health outcomes. Racism increases the risk of preterm birth, but standardized measurement metrics are elusive. This narrative synthesis examines literature on measures of racial discrimination used in preterm birth research.

DATA SOURCES

Six databases (CINAHL, Cochrane, EMBASE, PubMed [MEDLINE], Scopus, Web of Science) and ClinicalTrials.gov were searched. Search terms were categorized into three groups (racism terms, measurement terms, preterm birth terms) to identify original research articles that explored associations between racism and preterm birth. English-language, original research articles with U.S. populations were included.

METHODS OF STUDY SELECTION

Studies were excluded if conducted in only White populations, if only paternal factors were included, or if only racial differences in preterm birth were described. Articles were independently reviewed by two blinded researchers for inclusion at every stage of screening and data extraction; a third reviewer resolved discrepancies.

TABULATION, INTEGRATION, AND RESULTS

Sixty studies were included in the final analysis. Articles primarily included measures examining interpersonal forms of racism (n=17) through the Experiences of Discrimination and Everyday Discrimination scales, neighborhood composition (n=22) with the Neighborhood Deprivation Index and the Index of Concentration at the Extremes, policy-level racism (n=12) through institutions such as residential racial segregation or policy inequities, or multiple forms (n=9).

CONCLUSION

Among studies, assessment methods and application of constructs varied. This heterogeneity poses significant challenges to understanding associations between racial discrimination and preterm birth and to describing potential etiologic pathways of preterm birth, which ultimately hinders development of effective intervention. Strategies to capture multilevel exposures to racism require the development and expansion of metrics that are culturally inclusive, empirically valid, and reliable among Black pregnant populations.

Sexual Orientation-Related Nondiscrimination Laws and Maternal Hypertension Among Black and White U.S. Women

Background: Black women and sexual minority women are more likely to report adverse maternal health. Little research has investigated maternal health disparities at the intersection of race/ethnicity and sexual orientation or the mechanisms that contribute to these disparities. Materials and Methods: We analyzed data from the National Longitudinal Study of Adolescent to Adult Health. Our sample was restricted to Black and White women who had at least one live birth and were followed-up in Wave V of the data (n = 3,396). We used multivariable logistic regression to analyze the associations between race, sexual orientation identity, and a four-item state-level index of sexual orientation-related nondiscrimination laws. Results: We found that higher numbers of state-level sexual orientation-related nondiscrimination laws were associated with lower risk of maternal hypertension among U.S. women overall (odds ratio [OR] = 0.82, 95% confidence interval [CI] 0.73-0.93), and Black women had a higher risk of maternal hypertension relative to White women (OR = 1.32, 95% CI 1.00-1.79). Interactions between race, sexual orientation identity, and sexual orientation-related policies show that, regardless of sexual orientation identity, sexual orientation-related nondiscrimination laws were associated with a lower risk of maternal hypertension among White mothers (OR = 0.80, 95% CI 0.70-0.92). However, among Black women, these laws were associated with a lower risk of maternal hypertension among lesbian and bisexual women (OR = 0.18, 95% CI 0.05-0.68) only. Conclusions: Laws that prevent discrimination related to sexual orientation in various societal domains may play an important role in improving maternal health outcomes among White women in general and Black lesbian and bisexual women in particular.

Measuring institutional and structural racism in research on adolescence and developmental science

Dismantling racism and oppression in adolescence requires sound measurement and rigorous methods. In this commentary, we discuss the measurement of institutional and structural racism and approaches to operationalizing structures and systems in adolescent research. Drawing on a recent framework for the conceptualization, measurement, and analysis of institutional racism and health (Needham et al., Journal of Racial and Ethnic Health Disparities, in press), we highlight several considerations for measuring institutional and structural racism. These include definitional issues, the tension between individual- and area-level measures, questions of timing, and matters of design and analysis. We conclude with suggestions to address gaps in existing literature and call for transdisciplinary training, collaboration, and partnership to promote the healthy development of Black and Indigenous People of Color (BIPOC) adolescents and young people.

Disparities in infant mortality by maternal race and Hispanic origin, 2017-2018

Disparities in infant mortality by race and Hispanic origin groups continue to persist in the United States. Maternal and infant characteristics known to be associated with infant mortality vary by race and ethnicity. This report describes racial and ethnic disparities in infant mortality in the United States using the 2017-2018 cohort linked birth/infant death files from the National Vital Statistics System. Distributions of births and infant mortality rates are described by selected maternal and infant characteristics. Adjusted rates and rate ratios from logistic regression models, compared to unadjusted rates and ratios, show the extent to which race and Hispanic origin disparities would be attenuated if all groups had the same distributions of select maternal and infant factors. Results support the premise that the different distributions of several variables across racial/ethnic groups, most notably gestational age, account for a significant portion of the disparities in infant mortality between racial/ethnic groups.

Inequities in quality perinatal care in the United States during pregnancy and birth after cesarean

OBJECTIVE

High-quality, respectful maternity care has been identified as an important birth process and outcome. However, there are very few studies about experiences of care during a pregnancy and birth after a prior cesarean in the U.S. We describe quantitative findings related to quality of maternity care from a mixed methods study examining the experience of considering or seeking a vaginal birth after cesarean (VBAC) in the U.S.

METHODS

Individuals with a history of cesarean and recent (≤ 5 years) subsequent birth were recruited through social media groups to complete an online questionnaire that included sociodemographic information, birth history, and validated measures of respectful maternity care (Mothers on Respect Index; MORi) and autonomy in maternity care (Mother's Autonomy in Decision Making Scale; MADM).

RESULTS

Participants (N = 1711) representing all 50 states completed the questionnaire; 87% planned a vaginal birth after cesarean. The most socially-disadvantaged participants (those less educated, living in a low-income household, with Medicaid insurance, and those participants who identified as a racial or ethnic minority) and participants who had an obstetrician as their primary provider, a male provider, and those who did not have a doula were significantly overrepresented in the group who reported lower quality maternity care. In regression analyses, individuals identified as Black, Indigenous, and People of Color (BIPOC) were less likely to experience autonomy and respect compared to white participants. Participants with a midwife provider were more than 3.5 times more likely to experience high quality maternity care compared to those with an obstetrician.

CONCLUSION

Findings highlight inequities in the quality of maternal and newborn care received by birthing people with marginalized identities in the U.S. They also indicate the importance of increasing access to midwifery care as a strategy for reducing inequalities in care and associated poor outcomes.

"This work that we're doing is bigger than ourselves": A qualitative study with community-based birth doulas in the United States

CONTEXT

Community-based birth doulas support pregnant women, transgender men, and gender non-binary individuals during the perinatal period and provide essential services and expertise that address health inequities, often taking on additional roles to fill systemic gaps in perinatal care in the United States (US). Despite the benefits that community-based birth doulas provide, there is little research exploring the work-related conditions and stressors community-based doulas experience. To address this gap, we examined the work experiences, related stressors, and stress management strategies of individual community-based birth doulas.

METHODS

In this qualitative, descriptive study we conducted 18 interviews in March through June 2021 with individuals who self-identified as community-based doulas working in underserved communities in the US. We analyzed the interviews for themes, which we defined and finalized through team consensus.

RESULTS

The doulas reported engaging in specific strategies in their work to address perinatal inequities. They also described facing several work-related stressors, including witnessing discrimination against clients, experiencing discrimination in medical environments, and struggling with financial instability. To mitigate these stressors and job-related challenges, interviewees reported they relied on doula peer support and reconnected with their motivations for the work.

CONCLUSIONS

Community-based doulas provide essential services and expertise which address inequities and systemic gaps in perinatal care. However, as they work to improve perinatal health, doulas themselves are providing equity work amidst an inequitable system and with insufficient political or financial support. Increased compensation and systemic support which acknowledges the breadth of services provided is needed to strengthen and sustain this critical part of the perinatal workforce.

Racial and Socioeconomic Disparities in Cardiovascular Outcomes of Preeclampsia Hospitalizations in the United States 2004-2019

Background

Preeclampsia is associated with higher in-hospital cardiovascular events and mortality with known disparities by race/ethnicity, but data on the interaction between income and these outcomes remain limited.

Objectives

This study investigated racial and socioeconomic disparities in cardiovascular outcomes of preeclampsia at delivery hospitalizations.

Methods

We analyzed National Inpatient Sample data using International Classification of Diseases-9th Revision/-10th Revision codes between 2004 and 2019. We identified a total of 2,436,991 delivery hospitalizations with preeclampsia/eclampsia as a primary diagnosis representing White (43.1%), Black (18.4%), Hispanic (18.7%), and Asian or Pacific Islander (A/PI; 3.3%) women. We stratified the population based on median household income (low income, medium income, and high income). Logistic regression and propensity-matched analysis were used for reporting outcomes adjusted for age, hospital region, and baseline comorbidities.

Results

Black Hispanic, and A/PI women with preeclampsia had higher in-hospital mortality compared with White women across all groups of income. Hispanic women had lower odds of peripartum cardiomyopathy (PPCM) compared with White women. A significant interaction effect was observed with race/ethnicity and median household income for in-hospital mortality and PPCM with preeclampsia. Furthermore, high-income Black women had higher odds of PPCM, stroke, acute kidney injury, heart failure, cardiac arrhythmia, and venous thromboembolism compared with low-income White women.

Conclusions

Women with preeclampsia experience significant racial/ethnic and socioeconomic disparities in inpatient mortality and cardiovascular outcomes at delivery. Across all income groups, Black, Hispanic, and A/PI women experience higher odds of in-hospital mortality compared with White women. Furthermore, high-income Black women had greater odds of many CV complications compared with low-income White women.

State Policies, Racial Disparities, and Income Support: A Way to Address Infant Outcomes and the Persistent Black-White Gap?

Low birth weight and preterm births vary by state, and Black mothers typically face twice the risk that their white counterparts do. This gap reflects an accumulation of psychosocial and material exposures that include interpersonal racism, differential experience with area-level deprivation such as residential segregation, and other harmful exposures that the authors refer to as "institutional" or "structural" racism. The authors use logistic regression models and a dataset that includes all births from 1994 to 2017 as well as five state policies from this period-Aid to Families with Dependent Children/Temporary Aid for Needy Families, housing assistance, Medicaid, minimum wage, and the earned income tax credit (EITC)-to examine whether these state social policies, designed to provide a financial safety net, are associated with risk reduction of low birth weight and preterm birth to Black and white mothers, and whether variations in state generosity attenuate the racial inequalities in birth outcomes. The authors also examine whether the relationship between state policies and racial inequalities in birth outcomes is moderated by the education level of the mother. We find that the EITC reduces the risk of low birth weight and preterm birth for Black mothers. The impact is much less consistent for white mothers. For both Black and white mothers, the benefits to birth outcomes are larger for mothers with less education.

Spotlighting Black Adolescent Development in the Shadow of Racism: A Commentary

The special issue brings together scholarship that expands our understanding of the adverse effects of interpersonal, online, and vicarious racial discrimination on Black adolescents' psychosocial well-being and sociocultural factors (e.g., racial socialization and positive racial identity) that mitigate these effects. It also focuses attention on ways that adolescents' behavior and characteristics shape racial socialization. Some of the critical tasks that lie ahead include elevating a developmental perspective, documenting developmental pathways, directly assessing proximal mediating processes, giving more attention to the robustness and replicability of findings, and expanding levels of analyses and outcomes to include both macro-structural indicators and indicators of physiological and neuropsychological functioning.

Area-level racial prejudice and health: A systematic review

BACKGROUND

In recent years, there has been growing interest in "moving beyond the individual" to measure area-level racism as a social determinant of health. Much of this work has aggregated racial prejudice data collected at the individual-level to the area-level.

OBJECTIVE

As this is a rapidly emerging area of research, we conducted a systematic literature review to describe evidence of the relationship between area-level racial prejudice and health, whether results differed by race/ethnicity, and to characterize key conceptual and methodological considerations to guide future research.

METHOD

We searched four interdisciplinary databases for US-based, peer-reviewed articles measuring area level racial prejudice by aggregating individual-level indicators of racial prejudice and examining associations with mental or physical health outcome(s). Data extraction followed PRISMA guidelines and also included theory and conceptualization, pathways to health, and strengths and limitations.

RESULTS

Fourteen of 14,632 identified articles met inclusion criteria and were included in the review. Health outcomes spanned all-cause (n = 4) and cause-specific (n = 4) mortality, birth outcomes (n = 4), cardiovascular outcomes (n = 2), mental health (n = 1), and self-rated health (n = 1). All studies found a positive association between area-level racial prejudice and adverse health outcomes among racial/ethnic minoritized groups, with four studies also showing a similar association among Whites. Engagement with formal theory was limited and exposure conceptualization was mixed. Methodological considerations included unmeasured confounding and trade-offs between generalizability, self-censorship, and specificity of measurement.

CONCLUSIONS

Future research should continue to develop the conceptual and methodological rigor of this work and test hypotheses to inform evidence-based interventions to advance population health and reduce racial health inequities. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Addressing Systemic Racism in Birth Doula Services to Reduce Health Inequities in the United States

Purpose: Birth doulas support pregnant people during the perinatal period. Evidence of doulas' positive impacts on pregnancy and birth outcomes, particularly among underserved populations, supports expanding access. However, health workforce-related barriers challenge the development of robust doula services in the United States. This study examined the various approaches organizations have taken to train, recruit, and employ doulas as well as their perspectives on what system-level changes are needed to redress health inequities in underserved communities and expand access to birth doula services.

Methods: In addition to literature and policy reviews, we conducted 16 semistructured interviews from March to August 2020 with key informants from organizations involved in training, certifying, advocating for, and employing doulas, and informants involved in state policy making. We analyzed data using qualitative analysis software to identify cross-cutting themes.

Results: The landscape of organizations involved in doula training and certification is diverse. In discussing their training and curriculum, interviewees from large organizations and community-based organizations (CBOs) stressed the importance of incorporating a focus on structural racism in maternal health into training curricula. CBOs specifically offered three areas of systems-level change that can help equitably grow doula services: the importance of addressing structural racism, changing the balance of power in decision making and policy making, and a cautious approach to Medicaid reimbursement.

Conclusion: This study provides evidence of how doula organizations move the field toward better serving the specific needs of underserved populations. It recognizes the expertise of CBOs in developing policy to expand doula services to communities in need. The information from this study highlights the complexities of facilitating consistency across doula training and certification requirements and implementing a sustainable funding mechanism while also meeting communities' unique needs.

Role of discrimination and resilience on birth weight: A systematic examination in a sample of Black, Latina, and White women

Introduction:

Health inequities begin before birth with Black women being more likely to have low birth weight babies than White and Latina women. Although both Latina and Black women experience discrimination, only Black women appear to be affected.

Methods:

In this study using medical records and face-to-face interviews, we systematically examined the role of discrimination (daily, environmental, vicarious) on continuous birth weight (controlling for gestational age and baby’s gender) in a sample of 329 Black, Latina, and White pregnant women, as well as whether familism, prayer, and/or discrimination attribution buffered this association.

Results:

Linear regression analyses revealed that only prayer acted as a resilience factor, with Latina women appearing to benefit from prayer in the link between vicarious and daily discrimination on birth weight conditional on gestational age, whereas Black women showed no moderation and White women showed an exacerbation in the link.

Discussion:

The results of this study suggest that sociocultural norms may play a role in explaining the Latina epidemiological paradox, but more research is needed to understand the significance.

State-Level Regulations Regarding the Protection of Sexual Minorities and Birth Outcomes: Results From a Population-Based Cohort Study

OBJECTIVE

We leverage state-level variability in social policies that confer legal protections for sexual minorities (e.g., employment nondiscrimination acts) and examine their association with birth outcomes among sexual minority women.

METHODS

We link measures of structural protections (i.e., social policies) to a prospective, population-based cohort of US adults-the National Longitudinal Study of Adolescent to Adult Health ( n = 7913 total singleton births, n = 274 singleton births to bisexual women, n = 53 singleton births to lesbian women)-which includes measurement of key risk factors for birth outcomes over the life course.

RESULTS

Lesbian, gay, bisexual (LGB) policy protections were associated with better birth outcomes for lesbian women. For example, among lesbian women, the predicted birth weight for infants in states with no policy protections was 3.01 kg (95% confidence interval = 2.71-3.30) but was 3.71 kg (95% confidence interval = 3.46-3.96) in states with three or four policy protections. In negative control analyses, there was no association between LGB policy protections and birth outcomes among the nonstigmatized group (i.e., heterosexual women), providing evidence of specificity. Furthermore, in states with the most LGB policy protections, lesbian women were at lower risk for preterm births and had infants with higher birth weights than heterosexual and bisexual women. These associations remained robust after adjusting for 13 risk factors, including demographics, prior and current indicators of socioeconomic status, preconception and perinatal risk factors, and neighborhood characteristics.

CONCLUSIONS

These results provide novel evidence that sexual orientation-related policy protections, measured at the state level, are associated with a decreased risk for adverse birth outcomes among lesbian women.

Impact of paternal presence and parental social-demographic characteristics on birth outcomes

OBJECTIVES

Maternal race, marital status, and social environment impact risk of preterm delivery and size for gestational age. Although some paternal characteristics such as age are associated with pregnancy outcomes, the influence of the paternal presence, race/ethnicity and adverse life events is not well known. The objective of the study was to assess birth outcomes in mothers with a paternal presence compared to those without during the post-partum period. The secondary aim was to determine whether paternal race is associated with birth outcomes.

METHODS

This was a cross-sectional study using parental surveys linked with birth certificate data from 2016 to 2018. Adverse birth composite outcomes (ABCO) including small for gestational age (SGA), prematurity or neonatal intensive care unit admission (NICU) were assessed.

RESULTS

A total of 695 parents were analyzed (239 single mothers and 228 mother-father pairs). Compared to mothers with a father present, mothers without a father present exhibited increased odds of ABCO, prematurity and NICU. Non-Hispanic Black fathers had increased odds of ABCO and NICU compared to Non-Hispanic Whites (NHW). Hispanic fathers had increased odds of NICU compared to NHW.

CONCLUSIONS

Paternal absence in the post-partum period and paternal race were both independently associated with ABCO and NICU. Assessment of paternal presence and paternal race in clinical practice may help identify opportunities for additional support necessary to optimize birth outcomes.

Experiences of Quality Perinatal Care During the US COVID-19 Pandemic

INTRODUCTION

Quality perinatal care is recognized as an important birth process and outcome. During the coronavirus disease 2019 (COVID-19) pandemic, quality of perinatal care was compromised as the health care system grappled with adapting to an ever-changing, uncertain, and unprecedented public health crisis.

METHODS

The aim of this study was to explore the quality of perinatal care received during the COVID-19 pandemic in the United States. Data were collected via an online questionnaire completed by people who gave birth in the United States after March 15, 2020. The questionnaire included the Mothers on Respect Index and the Mothers Autonomy in Decision Making validated measures. Low-quality perinatal care was defined as decreased respect and/or autonomy in the perinatal care received. Responses were geocoded by zip code to determine COVID-19 case-load in the county on the date of birth. Multivariate regression analyses described associations between respect and autonomy in decision-making for perinatal care and levels of COVID-19 outbreak across the United States.

RESULTS

Participants (N = 707) from 46 states and the District of Columbia completed the questionnaire. As COVID-19 cases increased, participants' experiences of autonomy in decision-making for perinatal care decreased significantly (P = .04). Participants who identified as Black, Indigenous, and people of color, those who had an obstetrician provider, and those who gave birth in a hospital were more likely to experience low-quality perinatal care. Those with a midwife provider or who had a home birth were more likely to experience high-quality perinatal care in adjusted models.

DISCUSSION

Variability in experiences of high-quality perinatal care by sociodemographic characteristics, birth setting, and provider type may relate to implicit bias, structural racism, and inequities in maternal health and COVID-19 outcomes for birthing people from marginalized communities.

Structural Intersectionality as a New Direction for Health Disparities Research

This article advances the field by integrating insights from intersectionality perspectives with the emerging literatures on structural racism and structural sexism-which point to promising new ways to measure systems of inequality at a macro level-to introduce a structural intersectionality approach to population health. We demonstrate an application of structural intersectionality using administrative data representing macrolevel structural racism, structural sexism, and income inequality in U.S. states linked to individual data from the Behavioral Risk Factor Surveillance System to estimate multilevel models (N = 420,644 individuals nested in 76 state-years) investigating how intersecting dimensions of structural oppression shape health. Analyses show that these structural inequalities: (1) vary considerably across U.S. states, (2) intersect in numerous ways but do not strongly or positively covary, (3) individually and jointly shape health, and (4) are most consistently associated with poor health for black women. We conclude by outlining an agenda for future research on structural intersectionality and health.

Progress and push-back: How the killings of Ahmaud Arbery, Breonna Taylor, and George Floyd impacted public discourse on race and racism on Twitter

This study examined whether killings of George Floyd, Ahmaud Arbery, and Breonna Taylor by current or former law enforcement officers in 2020 were followed by shifts in public sentiment toward Black people. Methods: Google searches for the names "Ahmaud Arbery," "Breonna Taylor," and "George Floyd" were obtained from the Google Health Application Programming Interface (API). Using the Twitter API, we collected a 1% random sample of publicly available U.S. race-related tweets from November 2019-September 2020 (N = 3,380,616). Sentiment analysis was performed using Support Vector Machines, a supervised machine learning model. A qualitative content analysis was conducted on a random sample of 3,000 tweets to understand themes in discussions of race and racism and inform interpretation of the quantitative trends. Results: The highest rate of Google searches for any of the three names was for George Floyd during the week of May 31 to June 6, the week after his murder. The percent of tweets referencing Black people that were negative decreased by 32% (from 49.33% in November 4-9 to 33.66% in June 1-7) (p < 0.001), but this decline was temporary, lasting just a few weeks. Themes that emerged during the content analysis included discussion of race or racism in positive (14%) or negative (38%) tones, call for action related to racism (18%), and counter movement/arguments against racism-related changes (6%). Conclusion: Although there was a sharp decline in negative Black sentiment and increased public awareness of structural racism and desire for long-lasting social change, these shifts were transitory and returned to baseline after several weeks. Findings suggest that negative attitudes towards Black people remain deeply entrenched.

Whither weathering? The variable significance of age in Black-White low birth weight disparities

This paper uses birth certificate data to provide novel estimates of the age-specific risk of a low birth weight birth (LBW, an infant born weighting <2500 g) for U.S.-born non-Hispanic Black and White mothers, and finds that patterns vary markedly over space and time. Notably, risk of an LBW birth for Black mothers increased much more steeply with age in 1991-94 than in 2014-17. This decline in LBW risks among older Black mothers led to a decline in the Black-White LBW gap of more than half a percentage point. Both patterns and changes were regional; while age gradients on the Black-White LBW gap were lowest in the South in 1991-94, by 2014-17 they had increased in the South and declined in the rest of the country. These descriptive data allow a new examination of hypotheses regarding the causes of age-specific racial LBW gaps. Research has found that racial disparities in a number of health outcomes, including LBW, increase with age, leading some to speculate that this increase is due to the cumulative effects of exposure to disadvantage. The large degree of variability in Black-White LBW disparities suggests that age-specific causes may also play a role. A series of counterfactual trend analyses explore the roles of two specific mechanisms, smoking and hypertension, and compares these to a more fundamental indicator of socioeconomic status: education.

Neighborhood cognitive amenities? A mixed-methods study of intellectually-stimulating places and cognitive function among older Americans

Neighborhoods structure health and wellbeing in later life. Local spaces can encourage physically active and socially engaged aging in place, and may also nurture opportunities for cognitively-stimulating creative and complex activities such as reading; playing and listening to music; learning; and engagement in galleries, performing arts, and museums. These activities are associated with better cognitive health outcomes. In this exploratory sequential mixed-methods study, thematic analysis of interviews and ethnographic fieldwork with 125 diverse older adults in the Minneapolis (MN) metropolitan area (mean age 71 years) explored how and where older adults participated in intellectually-stimulating neighborhood activities. Thematic analysis indicated that libraries, higher education campuses, and sites of arts and culture were frequented intellectually-stimulating places, with racial differences in perception and usage. The qualitative findings informed quantitative investigation of associations between these amenities and cognitive function in a large national sample of aging Black and white Americans (n=21,165, mean age 67 years) in the Reasons for Geographic and Racial Differences in Stroke Study. We used multilevel linear regression models to examine whether living in a neighborhood with higher kernel densities of libraries, higher education campuses, and arts/cultural sites had a net positive effect on cognitive function. Analysis identified statistically significant positive associations between arts/cultural sites and cognitive function, with a significantly larger effect size for white versus Black participants. The study contributes new evidence to the emerging ecological model of cognitive health. It critically considers racial disparities in access to health-promoting neighborhood infrastructure and opportunities to age well in place.

The relationship between air pollutants and maternal socioeconomic factors on preterm birth in California urban counties

BACKGROUND

Preterm birth is the leading cause of perinatal morbidity and mortality in the U.S. and disparities among racial and ethnic groups persist. While etiologies of preterm birth have not been fully elucidated, it is probable that environmental and social factors play a role.

OBJECTIVE

We hypothesized that there is an interactive association between exposure to fine particulate matter (PM_2.5) or ozone (O₃) and neighborhood socioeconomic factors that increase the risk of preterm birth.

METHODS

We conducted a retrospective study using geocoded birth certificate data between 2007 and 2011, daily ambient air quality data on PM_2.5 and O₃, and American Community Survey (2007-2011 5-year estimates) data to assess census tract-level socioeconomic factors in California urban counties.

RESULTS

Our study found a small positive association between maternal exposures to PM_2.5 and O₃ and preterm birth that varied by gestational exposure period. In mixed-effects models, we found an increase in the risk of preterm birth for a one-unit change in PM_2.5 averaged across the entire pregnancy (AOR = 1.02, 95% CI: 1.01, 1.02) and O₃ during 3-months pre-pregnancy (AOR = 1.03, 95% CI: 1.02, 1.04). Interaction between census tract-level factors and air pollutants showed an increase in the risk of preterm birth among mothers living in higher socioeconomic areas, though, a fixed cohort bias sensitivity analysis showed these associations were not significant.

SIGNIFICANCE

These findings substantiate previous studies that showed associations between air pollution and preterm birth, even as pollution levels have decreased. This study has important implications for policy decisions and may help inform research on potential mechanisms of preterm birth.

Social epigenomics: are we at an impasse?

Aim: Social scientists have placed particularly high expectations on the study of epigenomics to explain how exposure to adverse social factors like poverty, child maltreatment and racism - particularly early in childhood - might contribute to complex diseases. However, progress has stalled, reflecting many of the same challenges faced in genomics, including overhype, lack of diversity in samples, limited replication and difficulty interpreting significance of findings. Materials & methods: This review focuses on the future of social epigenomics by discussing progress made, ongoing methodological and analytical challenges and suggestions for improvement. Results & conclusion: Recommendations include more diverse sample types, cross-cultural, longitudinal and multi-generational studies. True integration of social and epigenomic data will require increased access to both data types in publicly available databases, enhanced data integration frameworks, and more collaborative efforts between social scientists and geneticists.

The Racial Configuration of Parent Couples and Premature Birth: an Analysis of the Utah Population Database

In this paper, we analyze detailed maternal and paternal race information in a 25-year time series of birth record data to consider racial inequities in premature births experienced by women of color and women within interracial parent couples. We analyze birth outcomes within Utah, a historically racially homogeneous state experiencing growing racial diversity and interracial marriage over the past two decades. Our analyses consider disparities in preterm birth according to maternal race and the interracial status of couples for all birth certificate records within the Utah Population Database from 1989 to 2015 (N = 1,148,818). Our results, consistent with a dyadic perspective on minority stress, indicate that maternal race and interracial parent-couple status are each significantly associated with heightened risk of premature birth. The odds of preterm birth are significantly greater among all four racialized groups in the analyses (African Americans, Asians, Native Americans, and Native Hawaiian or Pacific Islanders) as compared to White women. Furthermore, we find that mothers in mixed-race parent couples with either a white or a black father experience a greater risk of preterm birth than mothers parenting with a father of the same race. Our results suggest that in order to capture the complete perspective on racial-ethnic disparities in adverse birth outcomes, outcomes pivotal for subsequent health outcomes over the life course, it is critical to address racism's toxic effects across multiple levels of lived experience-from the individual level, to the parent dyad, to the local community and beyond.

Evaluating associations between area-level Twitter-expressed negative racial sentiment, hate crimes, and residents' racial prejudice in the United States

Background

The objective of the current study is to investigate whether an area-level measure of racial sentiment derived from Twitter data is associated with state-level hate crimes and existing measures of racial prejudice at the individual-level.

Methods

We collected 30,977,757 tweets from June 2015-July 2018 containing at least one keyword pertaining to specific groups (Asians, Arabs, Blacks, Latinos, Whites). We characterized sentiment of each tweet (negative vs all other) and averaged at the state-level. These racial sentiment measures were merged with other measures based on: hate crime data from the FBI Uniform Crime Reporting Program; implicit and explicit racial bias indicators from Project Implicit; and racial attitudes questions from General Social Survey (GSS).

Results

Living in a state with 10% higher negative sentiment in tweets referencing Blacks was associated with 0.57 times the odds of endorsing a GSS question that Black-White disparities in jobs, income, and housing were due to discrimination (95% CI: 0.40, 0.83); 1.64 times the odds of endorsing the belief that disparities were due to lack to will (95% CI: 0.95, 2.84); higher explicit racial bias (β: 0.11; 95% CI: 0.04, 0.18); and higher implicit racial bias (β: 0.09; 95% CI: 0.04, 0.14). Twitter-expressed racial sentiment was not statistically-significantly associated with incidence of state-level hate crimes against Blacks (IRR: 0.99; 95% CI: 0.52, 1.90), but this analysis was likely underpowered due to rarity of reported hate crimes.

Conclusion

Leveraging timely data sources for measuring area-level racial sentiment can provide new opportunities for investigating the impact of racial bias on society and health.

Hidden internet-based measure of discrimination and mental health of Black people

Incorporating the internet-based measure of discrimination obtained by Google Trends into state-level panel data, we conduct a fixed-effect model estimation to elucidate the relationship between racial discrimination and depression among Black people. We find that the deterioration of mental health among Black people, measured as the percentage of Black people with depression, is closely associated with our measure of discrimination.

Acknowledging and Addressing Allostatic Load in Pregnancy Care

The USA is one of the few countries in the world in which maternal and infant morbidity and mortality continue to increase, with the greatest disparities observed among non-Hispanic Black women and their infants. Traditional explanations for disparate outcomes, such as personal health behaviors, socioeconomic status, health literacy, and access to healthcare, do not sufficiently explain why non-Hispanic Black women continue to die at three to four times the rate of White women during pregnancy, childbirth, or postpartum. One theory gaining prominence to explain the magnitude of this disparity is allostatic load or the cumulative physiological effects of stress over the life course. People of color disproportionally experience social, structural, and environmental stressors that are frequently the product of historic and present-day racism. In this essay, we present the growing body of evidence implicating the role of elevated allostatic load in adverse pregnancy outcomes among women of color. We argue that there is a moral imperative to assign additional resources to reduce the effects of elevated allostatic load before, during, and after pregnancy to improve the health of women and their children.

Women's Reproductive Rights Policies and Adverse Birth Outcomes: A State-Level Analysis to Assess the Role of Race and Nativity Status

INTRODUCTION

Reproductive rights policies can potentially support or inhibit individuals' abilities to attain the highest standard of reproductive and sexual health; however, research is limited on how broader social policies may differentially impact women of color and immigrants in the U.S. This study examines the associations among state-level reproductive rights policies, race, and nativity status with preterm birth and low birth weight in the U.S.

METHODS

This was a retrospective, cross-sectional analysis of all births occurring within all the 50 states and the District of Columbia using vital statistics birth record data in 2016 (N=3,945,875). Modified log-Poisson regression models with generalized estimating equations were fitted to estimate the RR of preterm birth and low birth weight associated with tertiles of the reproductive rights policies index. Analyses were conducted between 2019 and 2020.

RESULTS

Compared with women in states with the most restrictive reproductive rights policies, women living in the least restrictive states had a 7% lower low birth weight risk (adjusted RR=0.93, 95% CI=0.88, 0.99). In particular, low birth weight risk was 8% lower among Black women living in the least restrictive states than among their counterparts living in the most restrictive states (adjusted RR=0.92, 95% CI=0.86, 0.99). In addition, low birth weight risk was 6% lower among U.S.-born Black women living in the least restrictive states than among those living in the most restrictive states, but this was marginally significant (adjusted RR=0.94, 95% CI=0.89, 1.00). No other significant associations were found for race-nativity-stratified models.

CONCLUSIONS

Women living in states with fewer restrictions related to reproductive rights have lower rates of low birth weight, especially for Black women.

Contraceptive selection and practice: Associations with self-identified race and socioeconomic disadvantage

Many researchers and policymakers have linked contraceptive programs to improvements in women's and children's socioeconomic outcomes. However, these studies have overlooked how socioeconomic status may be an initial driver of contraceptive choice and behavior. Here, I examine the relationship between a comprehensive measure of socioeconomic disadvantage, self-identified race, and contraceptive method selection at enrollment in a unique longitudinal study of contraceptive clients who received a new type of method at no cost. I then examine whether socioeconomic disadvantage has an association with contraceptive switching or discontinuation. I demonstrate that socioeconomic disadvantage decreases the chance of selecting any IUD, while Black racial membership increases the chance of selecting the 3-month injectable and Multiracial membership increases the chance of selecting the Vaginal Ring. I then demonstrate that socioeconomic disadvantage and self-identified race have intersectional and variable associations with switching, and, to a lesser extent, discontinuing methods. These findings offer an important insight for implementation in contraceptive programs: eliminating financial barriers to access contraceptive services does not eliminate the socioeconomic contexts that influence method selection and use that occur as part of everyday lived experiences. Taken cumulatively, these results suggest that contraceptive services should be offered to women in ways that ensure access to reproductive justice without obscuring the need for social changes in the institutions that create disadvantage and shape contraceptive use itself.

Social Determinants of Placental Health and Future Disease Risks for Babies

Birthweight is a well-known predictor of adult-onset chronic disease. The placenta plays a necessary role in regulating fetal growth and determining birth size. Maternal stressors that affect placental function and prenatal growth include maternal overnutrition and undernutrition, toxic social stress, and exposure to toxic chemicals. These stressors lead to increased vulnerability to disease within any population. This vulnerability arises from placental and fetal exposure to stressors during fetal life. The biological drivers linking various social determinants of health to compromised placental function and fetal development have been little studied.
