Objective:
RD833293: Administrative Core
The Southern Center on Environmentally Driven Disparities in Birth Outcomes (SCEDDBO) is governed through an Administrative Core that includes an Executive Committee composed of the Director, the two Co-Directors and the Project Manager; an Internal Steering Committee composed of members of the Executive Committee and the Directors of the Research Projects and the Facility and Community Outreach Cores, as well as a community member and the Director of the Durham County Health Department; and an External Advisory Committee composed of senior environmental health scientists, as well as community representatives, with expertise relevant to SCEDDBO, who provide informal consultation, as well as annual formal evaluation of Center research and outreach activities.
The specific aims of the Center's Administrative Core are to:
- Provide scientific direction and leadership.
- Coordinate and foster interactions among research project and facility core investigators.
- Provide administrative services for the Center.
- Direct the Young Investigators program.
- Represent Duke's SCEDDBO to the university, the community, the NIH, other Children's Environmental Health Centers across the United States, and the policy and scientific community interested in children's environmental health more broadly.
In all activities, SCEDDBO emphasizes the importance of diversity. The decision to focus on health disparities; the gender and racial diversity of Center leadership; the incorporation of natural, social, and biomedical scientists; a commitment to community-based participatory research; and efforts to promote the careers of promising new investigators are all indicative of the importance that we place on fostering environments where all people can prosper.
RD833293C001: Project A: Mapping Disparities in Birth Outcomes
Project A utilizes the conceptual framework of the weathering hypothesis, which posits that chronic and persistent stressors lead to accelerated biological aging of women, which in turn accounts for adverse birth outcomes among certain subpopulations. The central objective is to determine whether and to what extent joint exposures to socioeconomic and environmental stressors contribute to racial and ethnic health disparities in fetal growth restriction.
Using a geographically based nested study design moving from analysis of births for the entire state of North Carolina to six demographically and geographically distinct counties to a single health center and state-of-the-art geographic information systems applications with Bayesian spatial hierarchical modeling and other advanced spatial statistical approaches, the specific aims are to:
- Spatially link detailed birth record, fetal death certificates, socioeconomic, environmental, tax assessor, community-based, and clinical obstetric data at highly resolved scales for the state of North Carolina from 1990-2003.
- Refine the concept of fetal growth restriction by (a) developing a joint distribution for birthweight and gestation using bivariate modeling for live births and fetal deaths—both separately and jointly; and (b) defining it in terms of fetal and infant mortality, rather than percentile cut points.
- Determine whether and to what extent differential exposures to both environmental and social stressors help explain health disparities in fetal growth restriction among (a) African American women compared to Non-Hispanic White and Hispanic women, (b) older African American women compared to younger African American women, (c) Hispanic women compared to Non-Hispanic White and African American women, and (d) foreign-born Hispanic women compared to U.S.-born Hispanic women.
This project evaluates a large number of factors in diverse populations, providing broad relevance for birth outcomes across time, space and demography. Identifying social and environmental factors contributing to fetal growth restriction will improve our understanding of disease etiology and explain the racial disparity in disease incidence, leading to effective interventions against poor outcomes in all population groups.
RD833293C002: Project B: Healthy Pregnancy, Healthy Baby: Studying Racial Disparities in Birth Outcomes
The central objective of the Healthy Pregnancy, Healthy Baby Study is to determine how the interaction of environmental, social and host factors contributes to disparities in birth outcomes between African American and White women in the American South. There are four specific aims:
- Conduct a cohort study of pregnant women in Durham, NC, designed to correlate birth weight, gestation and birth weight x gestation with environmental, social and host factors.
- Develop community-level measures of environmental and social factors by inventorying neighborhood quality and the built environment in partnership with local community groups.
- Create a comprehensive data architecture, spatially resolved at the tax parcel level, of environmental, social and host factors affecting pregnant women by linking data from the cohort study and neighborhood assessments with additional environmental and socioeconomic data.
-
Determine whether and to what extent differential exposures explain health disparities in birth outcomes by applying innovative spatial and genetic statistical methods to:
- Identify environmental, social, and host factors that cluster to predict birth outcomes in the entire sample.
- Determine whether these clusters are more or less present in African American versus White populations and quantify the proportion of health disparities explained by differences in cluster frequency.
- Identify environmental, social, and host factors that cluster to predict birth outcomes within the African American and White subsamples and compare these clusters across racial groups.
RD833293C003: Project C: Perinatal Environmental Exposure Disparity and Neonatal Respiratory Health
- To determine whether maternal exposure to airborne particulates (PM) and/or ozone (1st hit) restricts fetal growth and/or postnatal growth, as well as impairs lung development/function in newborn mice.
- To determine whether PM and/or ozone exposure reprograms maternal inflammatory responses.
- To determine whether postnatal (2nd hit) ozone exposure further impairs postnatal somatic and lung development/function following maternal PM and/or ozone exposures.
- To determine whether genetic or developmental susceptibility to airway hyper-reactivity exacerbates maternal and/or postnatal exposure effects on postnatal somatic and lung development/function.
Progress Summary:
RD833293: Administrative Core
Announcement. The Administrative Core (AC) served as the host for Administrator Johnson when he traveled to Durham to announce the Southern Center on Environmentally Driven Disparities in Birth Outcomes (SCEDDBO) award. AC personnel worked with the Nicholas School and Duke University Offices of Communication and Government Relations to ensure that all substantive and organizational requests from the Administrator's office were fulfilled. A research roundtable allowed SCEDDBO investigators to brief the Administrator on scientific goals and objectives, as well as potential policy applications. The Administrator, in turn, provided helpful comments on the direction of the Center. In addition, a formal event was held on campus, where Administrator Johnson, Stanley Meiburg (U.S. Environmental Protection Agency [EPA]), Richard Brodhead (President, Duke University), and Marie Lynn Miranda (Principal Investigator, SCEDDBO) all offered remarks, followed by questions and answers (Q&A) from the audience.
RD833293C001: Project A: Mapping Disparities in Birth Outcomes
Over the past year, the Project A research team has met weekly to discuss new research ideas, review progress of current analysis and identify next steps, and work on manuscript preparation.
We have done considerable methodological work on how to synthesize categorical data sets to enhance inference. We are particularly interested in how to deal with a collection of data sets of varying sizes that are all relevant to a particular scientific question but which include different subsets of the relevant variables, with some overlap. This work attempts to synthesize cross-classified categorical data sets drawn from a common population where many of the sets are incomplete (i.e., one or more of the classification variables is unobserved) but at least one is completely observed. This is expected to reduce uncertainty about the cell probabilities in the associated multiway contingency table as well as for derived quantities, such as relative risks and odds ratios. We have made substantial progress on the underlying modeling and have developed a simulation example as well. A manuscript on this work has been submitted for publication.
Out of efforts to develop new spatial methodologies for addressing health disparities, additional methodological work on disaggregated spatial modeling for areal unit categorical data is currently under way. This work uses innovative statistical methodology that extends spatial disease mapping techniques to model subgroups within areal units using a spatially smoothed, multilevel, log-linear model. A presentation based on this work was given at the annual meeting of the American Public Health Association in November 2007, and a related manuscript is presently in submission. We also are exploring the public health applications of this methodology to elucidate health disparities across space and subgroups.
We have spent considerable time linking the detailed birth record data to EPA monitoring data on particulate matter up to 10 μm in size (PM10), particulate matter up to 2.5 μm in size (PM2.5), and ozone in order to study the impact of maternal exposure to air pollution on birth weight. We are focused especially on refining exposure metrics to most effectively characterize meaningful exposures, as well as to capture any windows of vulnerability. Significant progress has been made on the relationship between birth outcomes and exposure to particulate matter and ozone separately, and the current focus is determining how to characterize joint exposure to both particulate matter and ozone.
Our project on racial residential segregation is in an earlier stage of development but promises to reveal key insights into how to think about the spatial aspects of the social factors influencing health disparities. We are working to determine which facets of segregation best characterize the way community-level racial residential segregation acts to promote health disparities in birth outcomes. Although our initial efforts were statewide, we have since decided that given the significantly more detailed data available for Durham County, we will focus on this area while we work to determine what variables are most important to characterizing racial residential segregation in terms of its health consequences.
In addition, we have been working on specific analysis and manuscripts examining the impact of maternal age and birth order on birth weight, the joint distribution of birth weight and gestational age, and the etiology of racial disparities in maternal hypertensive disorders.
RD833293C002: Project B: Healthy Pregnancy, Healthy Baby: Studying Racial Disparities in Birth Outcomes
As of April 1, 2008, 933 women have been enrolled in the study, with only 46 women withdrawn or lost to follow-up. Women are recruited from Duke University Medical Center (DUMC) and Lincoln Community Health Center. Demographic data indicate that we are successfully recruiting women who are most at risk for adverse pregnancy outcomes, particularly low-income, low-educational attainment, and non-Hispanic Black women.
The following information is collected from participants in the Healthy Pregnancy, Healthy Baby Study:
- Psychosocial measures include: CES-D, perceived stress, self-efficacy, interpersonal support, paternal support, perceived racism, perceived community standing, pregnancy intention, John Henryism Active Coping Scale, and NEO Five Factor Inventory of personality.
- Environmental exposure survey measures include: short survey on fish consumption, smoking pattern and exposure to secondhand smoke, and drinking water source.
- Maternal and neonatal medical record abstraction includes: detailed prepregnancy medical and social history, antepartum complications, birth outcomes, and neonatal complications.
- Blood samples for genetic and environmental analysis to assess candidate genes related to environmental contaminant (nicotine, cotinine, cadmium, lead, mercury, arsenic, and manganese), metabolism, inflammation, vascular dysfunction, and stress response.
- Cord blood and placental samples currently are being stored for future genetic analysis and evaluation of activity at the maternal-fetal interface.
We have been highly successful in collection of participant-level data as well as biological samples, with greater than 90 percent attainment of maternal blood sample for genetic and environmental analyses. Collection of cord blood and placental samples, which began in June 2007, also has been successful, with approximately 150 delivery samples collected.
All maternal data is georeferenced (i.e., linked to the physical address of the mother) using geographic information system (GIS) software. The Healthy Pregnancy, Health Baby Study also includes an in-depth neighborhood assessment designed to capture both built environment and community-level social stressors and community resources. The cohort study and neighborhood assessment data are spatially linked to extensive environmental and demographic data at a highly resolved spatial scale.
To date, we have generated genotypes on 624 blood samples from pregnant women for 104 single nucleotide polymorphisms (SNPs) in 16 genes, primarily involved in either metabolism of heavy metals or immune response.
RD833293C003: Project C: Perinatal Environmental Exposure Disparity and Neonatal Respiratory Health
We have determined that postnatal ozone (1 ppm x 3h/d, 3 d/week x 4 weeks) significantly impairs postnatal weight gain in C56BL/6 mice. Air pollutant exposure at a vulnerable window of postnatal development impairs growth.
Postnatal ozone increases nebulized methacholine-induced airway hyperreactivity (AHR) in C57BL/6 mice measured at 4 weeks but not 3 weeks. Ozone-induced AHR is developmentally regulated.
We have found that prenatal instillation of particulate matter (St. Louis particle, NIST#1648) twice weekly in time-mated pregnant mice augments postnatal ozone-induced AHR in mice, measured at 4 weeks postnatal. Prenatal air pollutant exposure reprograms postnatal air pollutant responses that result in AHR. A manuscript is in preparation to report these findings.
In studies just completed in collaboration with M. Ian Gilmour, U.S. EPA, we exposed time-mated C56BL/6 pregnant mice to internal combustion engine diesel exhaust (0.5, 1 and 2 mg/m3 x 6 h/d, 5 d/week, from gestation day 617) versus air control. Pups delivered to exposed dams were exposed postnatally to ozone, as described above. Prenatal diesel exposure dose-dependently impaired lung compliance and pressure-volume loop hysteresis versus air or prenatal air postnatal ozone controls. There were parallel effects on nebulized methacholine challenge-induced AHR. Prenatal ambient exposures to diesel particulates at doses relevant to human environmental exposure worsened postnatal ozone-induced lung function and AHR.
Future Activities:
RD833293C001: Project A: Mapping Disparities in Birth Outcomes
We recently began the process of linking participants in Project B with their associated birth certificate record. We are excited to begin exploring the additional insights into the detailed birth record data that can be gleaned by linking these data with the rich dataset collected in Project B. This linkage not only will allow us to explore issues of data accuracy in the detailed birth record, but also will allow us to begin implementing the methods of synthesizing categorical data, discussed above.
RD833293C002: Project B: Healthy Pregnancy, Healthy Baby: Studying Racial Disparities in Birth Outcomes
In the upcoming year, we will continue to enroll study participants with our target sample size of 1,500 pregnant women.
We will begin preliminary analyses on approximately 700 to 800 participants with complete pregnancy data, genetic results and environmental results. Analyses will look at the joint impact of environmental, social, and host factors on birth outcomes, especially as they differ by race. Identification of such co-exposures could lead to development and implementation of strategies to prevent adverse birth outcomes, ultimately decreasing or eliminating the racial disparity.
Maternal blood samples will be analyzed for both protein and genetic associations with adverse birth outcomes. Maternal samples collected at 24 to 28 weeks gestation will be analyzed for protein levels involving markers of inflammation, vascular dysfunction and stress response. DNA analysis is well under way, with genotyping completed for several genetic polymorphisms regarding environmental contaminant metabolism, as well as inflammatory cytokines and chemokines. Genotyping will continue and include genes involved in the maternal stress response and vascular/endothelial cell dysfunction. Statistical analysis regarding candidate gene polymorphisms will begin in June 2008. We will continue to genotype SNPs in the candidate genes we had proposed, as well as genotyping new, pertinent genes, as the literature suggests (i.e., GRK2/GRK5 as described by Liggett, et al., 2008). In addition, during Year 2, we will begin genotyping functional polymorphisms such as the 5HTTLPR in the serotonin transporter.
RD833293C003: Project C: Perinatal Environmental Exposure Disparity and Neonatal Respiratory Health
We have developed a recent collaboration with M. Ian Gilmour, U.S. EPA, Research Triangle Park, NC, to enable us to perform prenatal diesel particle exposures at concentrations and doses that more closely resemble human environmental exposures. Because the thrust of our project is to determine combined exposure effects on pregnancy and postnatal somatic and lung development, we are working on developing a system to perform simultaneous or alternating diesel and ozone exposures. This novel exposure scheme now is being developed and will begin early in Year 2 of the project.
Major mechanistic questions underlie the link between prenatal exposure(s) and adverse neonatal outcomes. Because maternal inflammation is a mechanism central to many exposures implicated in fetal growth restriction, postnatal development and postnatal morbidities, our plan is to test the concept by performing the single and combined pre- and postnatal exposures using inbred mouse strains with genetically determined but differing inflammatory repertoires in Year 2.
