Wednesday & Thursday, April 27 – 28 | Virtual Workshop
Thursday, April 28, 2022 | Post-workshop Networking
The goals of this Environmental Health Disparities and Environmental Justice (EHD-EJ) Faculty sponsored workshop were to examine the effects of chemical and non-chemical stressors on adverse maternal and fetal health outcomes, discuss diseases specific to women and individuals assigned female at birth, and to assess the role of racial and ethnic disparities in these exposures. The concepts of early and lifetime exposures and the correlation between socioeconomic status and hazardous exposures in disproportionally impacted communities were explored with a focus on the synergistic impacts on women’s health.
This workshop fostered dialogue among NIEHS employees, outside researchers, and members of the community as participants examine racism as a public health issue. The ideas, strategies, opportunities, and recommendations that emerged from the workshop will be used to inform an action plan for NIEHS that integrates within the institute’s core values, promoting a path forward that reduces environmental health disparities.
Post-workshop breakout rooms were available by session following the conclusion of the workshop from 1:15 to 2:15 p.m. EDT on Thursday, April 28, to allow for networking and follow-up with speakers, attendees, and NIEHS staff and scientists who are able to participate.

Black and other pregnant people of color in the U.S. continue to experience vast inequities in maternal and child health outcomes, including preterm birth, infant and maternal mortality. A large body of research finds that such inequities are not explained by individual-level differences in socioeconomic position, health behaviors, or access to health care. Instead, their persistence arises from the macro-level features and functions of our society that dictate the distribution of power and resources across people and places. Increasingly emergent research has sought to quantify measures of structural racism – the totality of ways in which racial discrimination is embedded across mutually reinforcing societal systems – and other macro-level indicators of inequality for the purposes of empirically evaluating their association with population health inequities.
This presentation will provide an overview of various measures of structural racism used in population health research and summarize research findings related to its harmful impact on maternal and child health outcomes and inequities. It will include recommendations for future extensions in this area of research.

The public health burden of uterine leiomyomas (fibroids) in the U.S. is immense, with an annual estimated cost of up to $34 billion. These hormonally responsive smooth muscle tumors can substantially burden the millions of women they affect. Fibroid tumors are associated with pelvic pain, heavy bleeding, and infertility. Black women are disproportionately burdened by fibroids. They experience a higher risk of fibroids, an earlier age of onset, and more severe symptoms than non-Black women. However, critical empirical gaps exist in explaining racial disparities in the development and progression of fibroids. There remains a major void in empirical data linking life course social structural stressors to fibroid risk factors, morbidity, and response to medical treatment. Moreover, intersectionality. a critical theoretical framework that asserts that multiple marginalized social positions (e.g., race, gender) and processes (e.g., racism, sexism, classism) intersect to reflect privilege and inequality, has not been integrated broadly into the study of reproductive health. This presentation will discuss the core tenets of intersectionality and its relevance to inequities in environmental exposures and women’s health outcomes.
The presentation will feature three cases that highlight different measures of social-structural stressors. The first case study will discuss how natural hair discrimination, a form of intersectional discrimination experienced by Black women, influences the use of potentially harmful personal care products. The second case study will focus on the association of adverse childhood events, including sexual abuse, fibroid symptom severity, and symptom-related quality of life among a diverse sample of women undergoing hysterectomies for fibroid treatment. The third case study will use qualitative data to illustrate how fibroid management decisions among Black women are influenced by a range of factors including contemporary and historical medical racism.

She recently participated in SARS CoV-2 seroprevalence investigations with the Houston Health Department and Harris County Public Health. Symanski is currently serving as a sub-group co-chair of an International Agency for Research on Cancer (IARC) Working Group, Cobalt metal (without tungsten carbide or other metal alloys) and cobalt (II) salts; Trivalent and pentavalent antimony; and Weapons-grade tungsten (with nickel and cobalt) alloy, volume 131. Symanski is also co-directing in Spring 2022 the inaugural offering of a medical school course entitled: Environmental Health: What Every Physician Should Know.
Despite advances in healthcare, persistent racial/ethnic inequalities remain a barrier to improving maternal and child health in Houston, a city plagued by environmental justice and equity problems and a microcosm for exposures in the physical, social, and built environments, i.e., the environmental riskscape. Houston is also among the most racially and economically diverse cities in the U.S. Because the city has no zoning laws, many industrial facilities and waste sites are located within poor neighborhoods and neighborhoods of color – as a legacy of historic redlining practices. Consequently, exposures to chemical and non-chemical stressors are heightened among health disparity populations, leading to growing concerns about the health of Houston’s mothers and children. The overarching goal of the Maternal and Infant Environmental Health Riskscape (MIEHR) Research Center is to elucidate the contributions of the environmental riskscape to health disparities in Black and White pregnant women and infants in the greater Houston area. To achieve this goal, we are assembling a cohort of mother-infant dyads from three major obstetric hospitals in the Texas Medical Center to: 1) Assess associations between the mixture of metals and non-chemical stressors, including stress, discrimination, and impacts of disasters with preterm birth and 2) Interrogate maternal biological [e.g., circulating cell-free RNA (cfRNA)] and chemical [PAHs and metal] exposures, as well as features of the social and built environments, to develop disparities-aware classifiers for preterm birth. Identifying the role of combined exposures to chemical and non-chemical stressors and developing predictive classifiers that rely on attributes of individual- and place-level stressors will yield actionable findings that will inform interventions to mitigate disparities and improve the health and well-being of women and their children.

Anthropogenic pressures lead to rapid and significant changes in the environment, posing a threat to public health. Several studies confirm that some communities are disproportionately affected by environmental changes. Many of these communities have expressed concerns about the potential health effects of changes in their environment, but few have received support and guidance from researchers in implementing research projects based on their concerns. Our lab highlights community knowledge as a valuable source of information to explore the relationships between environmental factors and health. Most of our lab’s research concerns the potential health impacts of unconventional natural gas operations. To extract natural gas, the industry uses a technique called hydraulic fracturing, which typically involves the drilling of wells and the injection of a large volume of fracking fluid (water, sand, and various chemicals) to fracture the rock formation, freeing the trapped natural gas. Northeastern British Columbia (Canada) sits on an important source of natural gas with approximately 30,000 wells drilled so far. Some chemicals used or associated with hydraulic fracturing may contaminate the soil by accidental spills, leaks, or during disposal of wastewaters. Unconventional natural gas operations can release volatile organic compounds and trace elements naturally occurring in the rock formation. Many of these chemicals are known or suspected reproductive and development toxicants, carcinogens, endocrine disruptors, and respiratory irritants.
During this workshop, Dr. Caron-Beaudoin will present her research regarding the gestational exposure to contaminants associated with unconventional natural gas operations and maternal and birth outcomes in Northeastern British Columbia.
Investigating the Interplay between Environmental and Social Stressors on Maternal Reproductive Health
Carrie Breton, Sc.D., Keck School of Medicine of University of Southern California
Keck School of Medicine of the University of Southern California
Carrie Breton, Sc.D., is Professor of Preventive Medicine at the Keck School of Medicine of the University of Southern California (USC) and is Director of the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) Center for Environmental Health Disparities. She also co-directs the USC program site for the Environmental Influences on Child Health Outcomes (ECHO) national NIH program. Breton’s work addresses the interplay between genetics, epigenetics, and susceptibility to environmental exposures such as air pollution and tobacco smoke on health outcomes in children. Her work in the MADRES Center examines whether pre- and postpartum environmental exposures, coupled with exposures to psychosocial and built environment stressors, affect maternal and child cardiometabolic health outcomes, including perturbed infant growth trajectories and increased childhood obesity risk. Her work in ECHO takes a multigenerational life course approach to studying the contribution of the environment to the developmental origins of childhood and emerging adult respiratory and metabolic health. She has conducted several other studies investigating how environmental exposures alter epigenetic profiles in newborns and young children, and what roles those changes play in underlying disease risk.
Eliminating disparities in maternal health outcomes is a national priority, especially given the numerous adverse health sequelae. Moreover, pregnancy may be an underappreciated period of susceptibility to environmental exposures and impacts on later maternal health outcomes. Given the lack of data on the relationships between prenatal exposures and stressors with postpartum maternal health, we are currently investigating how exposures such as air pollution affect maternal health outcomes, including complications in pregnancy such as gestational diabetes and thyroid dysfunction, as well as depression and cardiometabolic health in the postpartum period within the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) Center.
Importantly, we are exploring whether different levels of individual or neighborhood level stressors make certain groups of individuals more or less vulnerable to the negative effects of pollutant exposures. In this workshop, we will share recent results investigating the effects of prenatal air pollutants on pregnancy complications and birth outcomes, as well as postpartum maternal health. We highlight that some of the strongest effects on maternal health and birth outcomes are found in participants with the highest levels of perceived stress and who live in neighborhoods experiencing the highest levels of cumulative environmental and social burden.

Women of color experience greater risks of adverse reproductive and fetal developmental outcomes than their white counterparts. Growing research shows that the causal factors driving these reproductive health disparities extend well beyond individual socioeconomic differences but are attributable in large part to the intersection of racist policies in housing, law enforcement, education, and healthcare among others, leading to systematic disadvantages, chronic psychosocial stress, and a disproportionate burden of exposure to reproductive toxicants. The adverse reproductive and fetal developmental effects of women’s exposure to a milieu of chemical and non-chemical stressors may also confer greater lifelong health risks on their offspring and contribute to a vicious intergenerational cycle of health disparity.
Disentangling the intersection of the effects of chemical and non-chemical reproductive stressors on fertility and fetal developmental effects is critically important for eliminating the disparities, yet there are formidable challenges. I will present data-driven examples to illustrate some of the challenges in characterizing the reproductive and fetal developmental risks of women’s exposure to environmental reproductive toxicants and the racial and ethnic disparities in their effects. The examples are intended to foster discussion of the opportunities and strategies for filling the existing data gaps.

Many of the diseases and disorders of widespread prevalence in the human population, and for which cures have been elusive, are deemed ‘complex’ disorders and attributed to multiple environmental and genetic factors. Yet, in general, experimental animal models of chemical exposure effects fail to capture the complexity and context of the human environment, or they focus predominantly on interactions with genetic factors. Our laboratory has attempted to generate more translationally relevant animal models of lead (Pb) exposures, to understand the actual risk to the central nervous system posed by interactions of lead with risk factors with which it shares biological substrates and common adverse outcomes.
These included combinations of developmental Pb exposures with prenatal stress and/or with offspring stress, based on the shared mediation by these risk factors through the hypothalamic-pituitary-adrenal axis and brain mesocorticolimbic systems. Such studies revealed that maternal and/or prenatal stress can enhance Pb neurotoxicity, and even unmask Pb effects not seen in the absence of stress. In some cases, combined Pb exposure and prenatal stress resulted in effects consistent with higher levels of Pb exposure alone. Additionally, Pb neurotoxicity was dramatically influenced by the type of behavioral experience that offspring had previously undergone, resulting in modified epigenetic profiles in the brain. Furthermore, the nature of these interactions was highly sex-dependent. In summary, studies of the neurotoxicity of chemicals such as Pb exposure alone, i.e., in the absence of other pertinent environmental risk factors, may result in misleading information as to exposure levels of concern and mechanisms underlying toxicity.

Previously, we have shown that Maternal Separation and Early Weaning (MSEW), a model of early life stress, exacerbates high fat diet (HF)-induced visceral obesity in female offspring compared to normally reared female mice. Here, we investigated the female-specific signature of lipid and kinase pathways in visceral fat when obesity is induced in mice previously exposed to MSEW. Visceral fat was collected to assess lipidomics, transcriptomics, serine/threonine kinase activity, and in vitro lipolysis assay. Female MSEW mice showed increased adiposity and triacylglycerol accumulation (44:2/FA 18:2+NH4 lipids), reduced mitochondrial DNA density, and decreased phosphorylation of seven phosphokinases, despite a similar number of preadipocytes, food intake, and energy expenditure.
Single-cell RNA sequencing in isolated pre- and mature adipocytes showed a ~9-fold downregulation of aquaglyceroporin 3 (Aqp3), a channel responsible for glycerol efflux. Obese MSEW mice displayed high levels of circulating and adrenal-derived aldosterone and visceral adipose tissue-derived corticosterone. As mineralocorticoid receptors (MR) can bind both of these hormones and promote fat cell expansion during obesity, we used the MR blocker spironolactone (100 mg/kg/day, 2 weeks), which normalized the elevated intracellular glycerol levels, and the number of large size adipocytes in MSEW mice compared to controls. This data provides new insights into the dysregulation of adipose tissue in female MSEW mice by identifying possible targets important in adipocyte hypertrophy. Furthermore, our data suggests that MR plays a role in the promotion of adipocyte hypertrophy in female MSEW mice by preventing glycerol release in favor of triglyceride formation and storage.

Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) is a Superfund Research program created in 2010 to study the effects of exposure to contaminants on preterm births and maternal and child health in Puerto Rico. One of PROTECT’s Community Engagement Core objectives is to share with the participants the results of their exposures to chemical and environmental substances during their pregnancy period and strategies to reduce them. During the pandemic, the report back process was affected by social distancing and the closure ordered by the government of Puerto Rico. To generate more accessible and immediate communication with the participants, the PROTECT community engagement team developed a "PROTECT Responde" initiative. The purpose of this initiative was to create an educational campaign developed for digital social media platforms such as Facebook, Youtube, and Instagram to inform participants about possible environmental pollutants and harmful chemicals that can be related to adverse effects on pregnancy in maternal and child health. This campaign, as well as other Community Engagement Core activities, are planned in the context of our Community Advisory Team composed of collaborators in maternal and child health from the participating Federally Qualified Health Centers (FQHCs), Community groups and participants. This team oversees the creation and development of campaign materials and all report back materials and strategies through regular meetings.
The COVID-19 pandemic forced our Community Engagement Core to adapt our implementation strategies, for example translating our printed educational materials to videos, interviews, and infographics through social media platforms, and integrate them into the closed-circuit TV at collaborating FQHCs. The Community Advisory Team were instrumental in reviewing and supporting PROTECT on the development of materials that would answer the needs of our participants and make sure the messages were relevant and understood. The content developed consisted of videos, infographics, and radio segments that educate about PROTECT findings studies of chemicals and environmental pollutants related to preterm birth and other health outcomes. The main aspects to consider in all the creative processes were the importance of cultural humility, sociodemographic characteristics, and adaptation of the scientific content to a general vocabulary. The "PROTECT Responde" initiative is being implemented in health centers and other community settings.
Abandoning Exclusivity for Authentic Collaborations with Communities
Tanya Khemet Taiwo, Ph.D., M.P.H., C.P.M., University of California Davis, Environmental Health Sciences Center
Janette Robinson Flint, Black Women for Wellness, Los Angeles
Tanya Khemet Taiwo, Ph.D., M.P.H., C.P.M., is an assistant professor in the Department of Midwifery and Director of the Master of Arts in Maternal-Child Health Systems program. She also provides midwifery care on a part-time basis at CommuniCare Health Centers, a Federally Qualified Health Center with clinics in urban and rural communities around the Sacramento area. These clinics are committed to the compassionate care of low-income families in a multidisciplinary setting. Taiwo comes from a family tradition of midwives, stretching back at least three generations. Her grandmother and her maternal aunts were midwives practicing in rural Jamaica. She apprenticed with midwives in Seattle, Senegal, and Jamaica.
Taiwo is an epidemiologist whose research examines the role of maternal prenatal stress on child neurodevelopment, and how these stressors interact with environmental exposures. Her concern for environmental exposures affecting pregnant women drives her as co-director of the Community Engagement Core at the UC Davis Environmental Health Sciences Center. She is also a research fellow at The Birth Place Lab at the University of British Columbia. At the Birth Place Lab, she is collaborating on the Giving Voice to Mothers Study, a community-based participatory research project that examines how race, ethnicity, and birthplace affect maternity care in the United States.
Janette Robinson Flint and Tanya Khemet Taiwo will draw on their collective decades of experience as reproductive and environmental justice activists and environmental justice researchers to engage participants with proven effective strategies for developing and sustaining equitable and effective partnerships. In this workshop, we will engage participants in critical thinking about the roots of environmental injustice and its impact on women’s health disparities, and how these systems continue to be perpetuated in environmental health policy and research priorities. We will examine where the environmental health community has failed to examine the unique exposures experienced by Black, Indigenous, and women of color – specifically, the exposures to chemical toxins in beauty, personal care, hair, and cleaning products.
This will be followed by a discussion of the importance and value of community engagement and how, when well done, can help close these gaps in knowledge and abandon the standard narrative that compartmentalizes environmental exposures, communities, and life experiences without attending to the social forces that shape these conditions. Participants will gain insights into community participatory research challenges and benefits, and build the skills needed to recognize and avoid performative or ineffective patterns of working with community partners that perpetuate racism, classism, and academic elitism. We will examine how researchers can move from the tendency toward tokenism and further marginalization, to power-sharing and meaningful engagement. Creating sustainable approaches to reduce health burdens requires effective and equitable collaborations of researchers engaged with affected communities and truly multi-disciplinary teams that extend beyond our limited perception of what multi-disciplinary means. In this manner, we can identify optimal targeted solutions, utilize research to build community resilience, improve enforcement measures, increase the environmental health literacy of the public, and empower communities most at risk.
Creating Authentic Partnerships between the Columbia Center for Children’s Environmental Health (CCCEH) and Community Youth
Julie Herbstman, Ph.D., Sc.M., Columbia University, Mailman School of Public Health
Yesibel Pimentel and Quincy L. Wise, Columbia Center for Children’s Environmental Health (CCCEH)
Julie Herbstman, Ph.D, is an environmental and molecular epidemiologist whose research area focuses on the effects of prenatal exposures to environmental pollutants and the molecular mechanisms underlying these associations. She is an Associate Professor in the Environmental Health Sciences Department at the Columbia University Mailman School of Public Health and is the Director of the Columbia Center for Children’s Environmental Health (CCCEH). She has expertise in the design, conduct, and analysis of epidemiologic studies that include biomarker data and directs multiple longitudinal birth cohort studies of children born in New York City. She leads a number of NIH-funded research projects looking at early life to endocrine-disrupting compounds, which frequently elicit sex-specific effects, including polybrominated diphenyl ethers (PBDE), pyrethroid pesticides, polycyclic aromatic hydrocarbons (PAH), phenols (including BPA) and phthalates, and their impact on child health and neurodevelopment as well as maternal health. She is also a Principal Investigator of a cohort grant within the NIH-funded nationwide Environmental Influences on Child Health Outcomes (ECHO) consortium.
Since 1998, the Columbia Center for Children’s Environmental Health (CCCEH) has been conducting community-based research in Northern Manhattan and the South Bronx neighborhoods of New York City to identify the harmful effects of early life exposure to environmental pollutants on children's health. Community partnerships are the keystone of this research and are instrumental in helping us identify community needs and ensure that our research has measurable and maximal translational impact. Beginning with WeACT for Environmental Justice, which was our original leading partner, we have expanded our collaborations with other community groups and now have 22 active members of our Community Advisory and Stakeholder Board (CASB). In collaboration with these groups, we have been elevating and amplifying the voices of youth within and around the community. Here, we provide an example of an issue (Beauty Justice) around which we extended our collaborations and ultimately our reach by engaging with and supporting our youth-based community members.
