Short Term Coping-Behaviors and Postpartum Health in a Population-Based Study of Women with a Live Birth, Stillbirth, or Neonatal Death.

Objective: Responding to the National Institutes of Health Working Group's call for research on the psychological impact of stillbirth, we compared coping-related behaviors by outcome of an index birth (surviving live birth or perinatal loss - stillbirth or neonatal death) and, among individuals with loss, characterized coping strategies and their association with depressive symptoms 6-36 months postpartum.

Methods: We used data from the Stillbirth Collaborative Research Network follow-up study (2006-2008) of 285 individuals who experienced a stillbirth, 691 a livebirth, and 49 a neonatal death. We conducted a thematic analysis of coping strategies individuals recommended following their loss.

Racial and ethnic inequities in stillbirth in the US: Looking upstream to close the gap: Seminars in Perinatology.

Though stillbirth rates in the United States improved over the previous decades, inequities in stillbirth by race and ethnicity have persisted nearly unchanged since data collection began. Black and Indigenous pregnant people face a two-fold greater risk of experiencing the devastating consequences of stillbirth compared to their White counterparts. Because race is a social rather than biological construct, inequities in stillbirth rates are a downstream consequence of structural, institutional, and interpersonal racism which shape a landscape of differential access to opportunities for health.

Spatial Variation in Very Preterm Birth to Hispanic Women Across the United States: The Role of Intensified Immigration Enforcement.

Introduction: Limited existing research suggests that immigration climate and enforcement practices represent a social determinant of health for immigrants, their families, and communities. However, national research on the impact of specific policies is limited. The goal of this article is to estimate the effect of county-level participation in a 287(g) immigration enforcement agreement on very preterm birth (VPTB, <32 weeks' gestation) rates between 2005-2016 among US-born and foreign-born Hispanic women across the United States.

Chronic Stress and Preconception Health Among Latina Women in Metro Atlanta.

Background: Underserved subgroups are less likely to have optimal health prior to pregnancy. We describe preconception health indicators (behavior, pregnancy intention, and obesity) among pregnant Latina women with and without chronic stress in metro Atlanta.

Design: We surveyed 110 pregnant Latina women enrolled in prenatal care at three clinics in Atlanta.

Perceptions of stress and resilience among Latina women enrolled in prenatal care in Metro Atlanta through an ecosocial lens.

Stress across the life course is highly prevalent, particularly among immigrant and racial/ethnic minority women who face adversities associated with structural and interpersonal racism. Understanding how women perceive and describe stress and resilience can provide cultural context to inform interventions to improve health among pregnant women facing adversity. The goal of this project was to examine how external stressors and coping strategies prior to and during pregnancy are reflected in Latina women's narratives about their lives through an Ecosocial framework.

Glucocorticoid receptor sensitivity in early pregnancy in an African American cohort.

Problem: Disruption in homeostatic feedback loops between inflammatory mediators and the hypothalamic-pituitary-adrenal (HPA) axis is a key mechanism linking chronic stress to inflammation and adverse health outcomes, including those occurring during pregnancy. In particular, alterations in glucocorticoid sensitivity may occur as a result of chronic stress, including that due to racial discrimination, and may be implicated in the persistent adverse maternal and infant health outcomes experienced by African Americans. While there are a few large-scale studies in human pregnancy that measure both cytokines and HPA axis hormones, to our knowledge, none directly measure glucocorticoid sensitivity at the cellular level, especially in an African American population.

Interpregnancy interval and risk of stillbirth: a population-based case control study.

Purpose: We examined the association between interpregnancy intervals (IPIs) and stillbirth (defined as fetal death ≥20 weeks), as both short and long IPIs have been associated with adverse perinatal outcomes. Prior pregnancy loss is also a known risk factor for stillbirth, and women who suffer a prior loss often have shorter IPIs. For these reasons, we also sought to quantify the proportion of the association between prior pregnancy loss and subsequent stillbirth risk that may be attributed to a short IPI.

Association of participation in a supplemental nutrition program with stillbirth by race, ethnicity, and maternal characteristics.

Background: Participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) has been associated with lower risk of stillbirth. We hypothesized that such an association would differ by race/ethnicity because of factors associated with WIC participation that confound the association.

Methods: We conducted a secondary analysis of the Stillbirth Collaborative Research Network's population-based case-control study of stillbirths and live-born controls, enrolled at delivery between March 2006 and September 2008.

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

The Weathering Effect is a theory that links stress exposure, over the life-course, with racial disparities in reproductive outcomes, through the effects of social adversity on a woman's body. The concept of maternal "weathering" captures cumulative somatic and psychological adversities that can exacerbate the effects of aging. Much of the evidence for weathering comes from observational studies linking self-report measures with reproductive outcomes.

Stillbirth, Inflammatory Markers, and Obesity: Results from the Stillbirth Collaborative Research Network.

Background: Obesity is associated with increased risk of stillbirth, although the mechanisms are unknown. Obesity is also associated with inflammation. Serum ferritin, C-reactive protein, white blood cell count, and histologic chorioamnionitis are all markers of inflammation.

Potentially Preventable Stillbirth in a Diverse U.S. Cohort.

Objective: To estimate the proportion of potentially preventable stillbirths in the United States.

Methods: We conducted a secondary analysis of 512 stillbirths with complete evaluation enrolled in the Stillbirth Collaborative Research Network from 2006 to 2008. The Stillbirth Collaborative Research Network was a multisite, geographically, racially, and ethnically diverse, population-based case-control study of stillbirth in the United States.

A population-based study of the effect of pregnancy history on risk of stillbirth.

Objective: To examine the effect of pregnancy history on the risk of stillbirth.

Methods: In a population-based cross-sectional study, data were reviewed from all women aged at least 20 years with singleton pregnancies in Finland between 2000 and 2010. The primary outcome-stillbirth-was defined as fetal death after 22 gestational weeks or death of a fetus weighing at least 500 g.

Fetal death certificate data quality: a tale of two U.S. counties.

Purpose: Describe the relative frequency and joint effect of missing and misreported fetal death certificate (FDC) data and identify variations by key characteristics.

Methods: Stillbirths were prospectively identified during 2006-2008 for a multisite population-based case-control study. For this study, eligible mothers of stillbirths were not incarcerated residents of DeKalb County, Georgia, or Salt Lake County, Utah, aged ≥13 years, with an identifiable FDC.

Route of Delivery in Women With Stillbirth: Results From the Stillbirth Collaborative Research Network.

Objective: To describe delivery management of singleton stillbirths in a population-based, multicenter case series.

Methods: We conducted a retrospective chart review of 611 women with singleton stillbirths at 20 weeks of gestation or greater from March 2006 to September 2008. Medical and delivery information was abstracted from medical records.

Improving surveillance for the hidden half of fetal-infant mortality: a pilot study of the expansion of the Pregnancy Risk Assessment Monitoring System to include stillbirth.

Purpose: In the United States, stillbirths (fetal deaths ≥ 20 weeks' gestation) are now more common than infant deaths. Nationally available data are limited, and little is known about women's experiences around the time of a loss. The Pregnancy Risk Assessment Monitoring System (PRAMS), a state-based survey of women with a recent live birth, could be expanded to include women who experienced a stillbirth.

The association of stillbirth with depressive symptoms 6-36 months post-delivery.

Background: Stillbirths (≥ 20 weeks' gestation), which account for about 1 in 200 US pregnancies, may grieve parents deeply. Unresolved grief may lead to persistent depression.

Methods: We compared depressive symptoms in 2009 (6-36 months after index delivery) among consenting women in the Stillbirth Collaborative Research Network's population-based case-control study conducted 2006-08 (n = 275 who delivered a stillbirth and n = 522 who delivered a healthy livebirth (excluding livebirths < 37 weeks, infants who had been admitted to a neonatal intensive care unit or who died).

Placental findings in singleton stillbirths.

Objective: To compare placental lesions for stillbirth cases and live birth controls in a population-based study.

Methods: Pathologic examinations were performed on placentas from singleton pregnancies using a standard protocol. Data were analyzed overall and within gestational age groups at delivery.

Bile acids in a multicenter, population-based case-control study of stillbirth.

Objective: We sought to compare bile acids in women with and without stillbirth in a population-based study.

Study Design: The Stillbirth Collaborative Research Network conducted a multisite, population-based case-control study of stillbirth (fetal deaths ≥20 weeks). Maternal sera were obtained at the time of enrollment and frozen at -80°C until assay for bile acids.

Antiphospholipid antibodies in stillbirth.

Objective: To compare antiphospholipid antibodies in deliveries with and without stillbirth using a multicenter, population-based case-control study of stillbirths and live births.

Methods: Maternal sera were assayed for immunoglobulin (Ig)G and IgM anticardiolipin and anti-β2-glycoprotein-I antibodies. Assays were performed in 582 stillbirth deliveries and 1,547 live birth deliveries.

A population-based case-control study of stillbirth: the relationship of significant life events to the racial disparity for African Americans.

Stillbirths (fetal deaths occurring at ≥20 weeks' gestation) are approximately equal in number to infant deaths in the United States and are twice as likely among non-Hispanic black births as among non-Hispanic white births. The causes of racial disparity in stillbirth remain poorly understood. A population-based case-control study conducted by the Stillbirth Collaborative Research Network in 5 US catchment areas from March 2006 to September 2008 identified characteristics associated with racial/ethnic disparity and interpersonal and environmental stressors, including a list of 13 significant life events (SLEs).

Measuring women's cumulative neighborhood deprivation exposure using longitudinally linked vital records: a method for life course MCH research.

A life course conceptual framework for MCH research demands new tools for understanding population health and measuring exposures. We propose a method for measuring population-based socio-environmental trajectories for women of reproductive age. We merged maternal longitudinally-linked births to Georgia-resident women from 1994 to 2007 with census economic and social measures using residential geocodes to create woman-centered socio-environmental trajectories.
