Multiparous Black and Latinx Women Face More Barriers to Prenatal Care than White Women

Use of Maternal Race and Weight Provides Equitable Performance in Serum Screening for Open Neural Tube Defects

BACKGROUND

Maternal serum alpha-fetoprotein (AFP) levels are used in screening for open neural tube defects (ONTD). Historical reports show that AFP levels and maternal weights are higher in self-reported Black than White individuals, but recent reports question the need to account for these variables in screening. Our study compares screening performance with and without accounting for race.

METHODS

Retrospective analysis was performed on deidentified prenatal screening records including maternal weight and self-reported race of White or Black. Gestational age-specific medians and weight-adjusted multiples of the median levels were calculated separately for each group and using a race-agnostic analysis. Outcome measures included the proportion of screen-positive results.

RESULTS

Records for analysis (n = 13 316) had an ultrasound confirmed gestational age between 15 and 21 completed weeks, singleton pregnancy, and self-reported race. Race was Black for 26.3%. AFP levels for pregnancies in Black individuals were higher than in White individuals: 6% to 11% depending on gestational age. Race-specific gestational age and maternal weight analyses resulted in similar screen-positive rates for self-reported White and Black individuals at 0.74% vs 1.00%, respectively (P = 0.14). However, use of race-agnostic analyses resulted in a screen-positive rate that was 2.4 times higher in Black than White individuals (P < 0.001).

CONCLUSION

These data show that the historical method of accounting for maternal race and weight in prenatal screening for ONTD provides equitable performance. Using a race-agnostic methodology results in an increased screen-positive rate and a disproportionate rate of required follow-up care for individuals who self-identify as Black.

Impact of Race/Ethnicity and Insurance Status on Obstetric Outcomes: Secondary Analysis of the NuMoM2b Study

OBJECTIVE

 This study aimed to investigate the impact of race/ethnicity and insurance status on obstetric outcomes in nulliparous women.

STUDY DESIGN

 Secondary analysis of the Nulliparous Pregnancy Outcomes Study Monitoring Mothers-To-Be. Obstetric outcomes included the development of a hypertensive event during pregnancy, need for a cesarean section, delivery of a preterm neonate, and postpartum hemorrhage.

RESULTS

 Of 7,887 nulliparous women, 64.7% were non-Hispanic White (White), 13.4% non-Hispanic Black (Black), 17.8% Hispanic, and 4.1% were Asian. Black women had the highest rates of developing new-onset hypertension (32%) and delivering preterm (11%). Cesarean deliveries were the highest in Asian (32%) and Black women (32%). Individuals with government insurance were more likely to deliver preterm (11%) and/or experience hemorrhage after delivery. In multivariable analyses, race/ethnicity was associated with hypertension and cesarean delivery. More important, the adjusted odds ratios for preventable risk factors, such as obesity, diabetes, and severe anemia were greater than the adjusted odds ratios for race/ethnicity in terms of poor maternal outcome.

CONCLUSION

 Although disparities were observed between race/ethnicity and obstetric outcomes, other modifiable risk factors played a larger role in clinical differences.

KEY POINTS

· Race or insurance alone had mixed associations with maternal morbidities.. · Race and insurance had low associations with maternal morbidities.. · Other, modifiable risk factors may be more important.. · Both social and biological factors impact health disparities..

Disparities by Race in Pregnancy Care and Clinical Outcomes in Women With Multiple Sclerosis: A Diverse Multicenter Cohort

BACKGROUND AND OBJECTIVES

Racial disparities exist in both neurologic and obstetric populations, underscoring the importance of evaluating pregnancy outcomes in diverse women with multiple sclerosis (MS). The objective of this multicenter retrospective study was to compare pregnancy care and outcomes between Black and Hispanic (underrepresented) and White women with MS.

METHODS

Demographic and clinical data were extracted from medical records of 9 US MS centers for women with MS/clinically isolated syndrome who delivered live births between 2010 and 2021. Sites identified at last 15 consecutive Black/Hispanic women and a matching number of White women. Socioeconomic factors, pregnancy, and MS care/outcomes were compared between groups (underrepresented and White and then Black and Hispanic) using Wilcoxon rank sum (U statistic and effect size r reported), χ2, t tests and logistic regressions as appropriate to data type. Multiple imputation by chained equation was used to account for missing data.

RESULTS

Overall, 294 pregnancies resulting in live births were analyzed ( 81 Black, 67 Hispanic, and 146 White mothers). Relative to underrepresented women, White women lived in areas of higher median (interquartile range [IQR]) Child Opportunity Index (79 [45.8] vs 22 [45.8], U = 3,824, r = 0.56, p < 0.0001) and were more often employed (84.9% vs 75%, odds ratio [OR] 2.57, CI 1.46-4.50, p = 0.0008) and privately insured (93.8% vs 56.8%, OR 11.6, CI 5.5-24.5, p < 0.0001) and more received a 14-week ultrasound (98.6% vs 93.9%, OR 4.66, CI 0.99-21.96, p = 0.027). Mode of delivery was significantly different between the three groups (X2(10,294) = 20.38, p = 0.03); notably, Black women had the highest rates of emergency cesarean deliveries, and Hispanic women highest rates of uncomplicated vaginal deliveries. Babies born to underrepresented women had lower median (IQR) birthweights than babies born to White women (3,198 g [435.3 g] vs 3,275 g [412.5 g], U = 9,255, r = 0.12, p = 0.04) and shorter median (IQR) breastfeeding duration (4.5 [3.3] vs 6.0 [4.2] months, U = 8,184, r = 0.21, p = 0.003). While underrepresented women were younger than White women (mean [SD] 30.9 [4.8] vs 33.8 [4.0], t = 1.97, CI 1.96-3.98, p < 0.0001), their median (Q1-Q3, IQR) Expanded Disability Status Scale was higher (1.5 [1-2.5, 1.5] vs 1 [0-1.5, 1.5], U = 7,260, r = 0.29, p < 0.0001) before pregnancy. Finally, medical records were missing more key data for Black women (19.7% missing vs 8.9% missing, OR 2.54, CI 1.25-5.06, p = 0.008).

DISCUSSION

In this geographically diverse multicenter cohort, underrepresented women entered pregnancy with higher disability and fewer health care resources. Pregnancy represents a pivotal window where structural factors affect maternal and fetal health and neurologic trajectories; it is a critical period to optimize care and health outcomes.

Child Care as a Barrier to Perinatal Health Care in Illinois

PURPOSE

Within a multi-state Collaborative Improvement and Innovation Network addressing the social determinants of health during 2017-2020, the Illinois Department of Public Health led an exploratory project to understand how the availability of child care affects maternal health care utilization. The project assessed whether lack of child care was a barrier to perinatal health care utilization and gathered information on health facility practices, resources, and policies related to child care DESCRIPTION: TWe surveyed (1) birthing hospitals (n = 98), (2) federally qualified health centers (FQHCs) (n = 40), and (3) a convenience sample of postpartum persons (n = 60).

ASSESSMENT

Each group reported that child care concerns negatively affect health care utilization (66% of birthing hospitals, 50% of FQHCs, and 32% of postpartum persons). Among postpartum persons, the most common reported reason for missing a visit due to child care issues was "not feeling comfortable leaving my child(ren) in the care of others" (22%). The most common child care resource reported by facilities was "staff watching children" (53% of birthing hospitals, 75% of FQHCs); however, most did not have formal child care policies or dedicated space for children. Fewer than half of FQHCs (43%) discussed child care at the first prenatal visit.

CONCLUSION

The project prompted the Illinois Title V program to add a child care-related strategy to their 2021-2025 Action Plan, providing opportunity for further examination of practices and policies that could be implemented to reduce child care barriers to perinatal care. Systematically addressing child care in health care settings may improve health care utilization among birthing/postpartum persons.

The Racial Disparities in Maternal Mortality and Impact of Structural Racism and Implicit Racial Bias on Pregnant Black Women: A Review of the Literature

BACKGROUND

The maternal mortality rate (MMR) in the United States (USA) continues to increase despite medical advances and is exacerbated by stark racial disparities. Black women are disproportionately affected and are three times more likely to experience a pregnancy-related death (PRD) compared to Non-Hispanic White (NHW) women.

METHODS

A literature review was conducted to examine the racial disparities in the United States' MMR, specifically among pregnant Black women. PubMed and key organizations (World Health Organization, Center for Disease Control and Prevention, American College of Obstetricians and Gynecologists, Alliance for Innovation on Maternal Health, Association of American Medical Colleges, U.S. Census Bureau, and U.S. Congress) were searched for publications after 2014.

RESULT

Forty-two articles were reviewed to identify the role of structural racism, implicit biases, lack of cultural competence, and disparity education on pregnant Black women. This review highlights that maternal health disparities for Black women are further impacted by both structural racism and racial implicit biases. Cultural competence and educational courses targeting racial disparities among maternal healthcare providers (MHCP) are essential for the reduction of PRDs and pregnancy-related complications (PRC) among this target population. Additionally, quality and proper continuity of care require an increased awareness surrounding the risk of cardiovascular diseases for pregnant Black women.

CONCLUSIONS

The surging MMR for Black women is a public health crisis that requires a multi-tiered approach. Interventions should be implemented at the provider and healthcare institution level to dismantle implicit biases and structural racism. Improving patient-provider relationships through increased cultural competency and disparity education will increase patient engagement with the maternal healthcare (MHC) system.

Healthcare Experiences of African American Women with the Fragile X Premutation

This study aims to understand the healthcare experiences of African American women with a fragile X premutation (PM). PM carriers are at risk for fragile X-associated conditions, including primary ovarian insufficiency (FXPOI) and neuropsychiatric disorders (FXAND). There is no racial/ethnic association with carrying a PM, but African American women historically experience barriers receiving quality healthcare in the USA. Obstacles to care may increase mental health conditions like anxiety and depression. Eight African American women with a PM were interviewed to explore disparities in receiving healthcare and to learn about psychosocial experiences during and after their diagnoses. Interviews were transcribed verbatim and independently coded by two researchers. A deductive-inductive approach was used, followed by thematic analysis to determine prominent themes. The average participant age was 52.3 ± 8.60 years, with a mean age at premutation diagnosis of 31 ± 5.95 years. Seven participants had children with FXS. Themes from interviews included healthcare experiences, family dynamics, and emotional/mental health after their diagnosis. Participants reported concerns about not being taken seriously by providers and mistrust of the medical institutions. Within families, participants reported denial, insensitivity, and isolation. Participants reported a high incidence of anxiety and depression. Both are symptoms of FXAND and stresses of systemic racism and sexism. The reported family dynamics around the news of a genetic diagnosis stand apart from other racial cohorts in fragile X research: interventions like family counseling sessions and inclusive support opportunities from national organizations could ease the impacts of a PM for African American women.

Postpartum Home Blood Pressure Monitoring Program: Improving Care for Hypertension During Postpartum after a Hospital Birth

BACKGROUND AND SIGNIFICANCE

Hypertensive disorders of pregnancy complicate about 10% of pregnancies and are a leading cause of maternal morbidity and mortality.

PURPOSE

The purpose of this quality improvement project was to evaluate a program to provide a home blood pressure monitor to all postpartum patients who had a hypertensive diagnosis and elevated blood pressure.

METHODS

The program includes a blood pressure monitor, instructions for its use, education about hypertension, and a guidance grid with standardized blood pressure parameters reviewed prior to discharge from the hospital. Patients are taught about potential adverse outcomes during postpartum. Patients are instructed to follow-up with their care provider based on the parameters. A retrospective medical record review was used to evaluate clinical outcomes.

RESULTS

Medical records of 185 patients indicated that 20% ( n = 36) who received the home BP monitor reported one or more mild-to-severe range blood pressure(s) during postpartum. Twenty-eight percent ( n = 52) had outpatient medication adjustments, including decreasing, increasing, starting, and discontinuing medications. Nine percent ( n = 17) of patients returned to the obstetric triage for evaluation. There was patient overlap between those experiencing elevated blood pressures, medication adjustments, and those who returned to hospital for evaluation.

CLINICAL IMPLICATIONS

Ongoing monitoring may improve identification and management of postpartum hypertension and potentially prevent progression to hypertensive-related adverse events.

Health Care Disparities in High-Risk Neonates

Long-standing health disparities in maternal reproductive health, infant morbidity and mortality, and long-term developmental outcomes are rooted in a foundation of structural racism. Social determinants of health profoundly affect reproductive health outcomes of Black and Hispanic women disproportionately; they have higher rates of death during pregnancy and preterm birth. Their infants are also more likely to be cared for in poorer quality neonatal intensive care units (NICUs), receive poorer quality of NICU care, and are less likely to be referred to an appropriate high-risk NICU follow-up program. Interventions that mitigate the impact of racism will help to eliminate health disparities.

The Biopsychosocial Model and Perinatal Health Care: Determinants of Perinatal Care in a Community Sample

Insufficient care in the perinatal period is associated with poorer maternal health, poorer perinatal outcomes, infant mortality, and health inequalities. Identifying the sources of and reducing the rates of insufficient care is therefore a major clinical and public health objective. We propose a specific application of the biopsychosocial model that conceptualizes prenatal and postpartum care quality as health markers that are influenced by psychological factors and family and social context. Clinic attendance data were abstracted from the electronic medical records of N = 291 participants enrolled in a longitudinal pregnancy cohort study of healthy women who have been followed since the first trimester; the Kotelchuck Index (KI) was calculated as an index of perinatal care utilization. Detailed prenatal psychological, social, and sociodemographic data were collected from self-report questionnaire and interview. Bivariate analyses indicated socio-demographic (e.g., race), psychological (e.g., response to perceived racism, affective symptoms, trauma experience), and social and family context (e.g., social support, family size) significantly influenced pre- and post-natal care utilization. Multivariate logistic regression analyses, adjusting for medical complications, identified social and family context as robust predictors of perinatal care utilization. The findings underscore the need for biopsychosocial models of health care and highlight several potential strategies for improving health care utilization.

Revisiting the Neuropathology of Sudden Infant Death Syndrome (SIDS)

Background: Sudden infant death syndrome (SIDS) is one of the leading causes of infant mortality in the United States (US). The extent to which SIDS manifests with an underlying neuropathological mechanism is highly controversial. SIDS correlates with markers of poor prenatal and postnatal care, generally rooted in the lack of access and quality of healthcare endemic to select racial and ethnic groups, and thus can be viewed in the context of health disparities. However, some evidence suggests that at least a subset of SIDS cases may result from a neuropathological mechanism. To explain these issues, a triple-risk hypothesis has been proposed, whereby an underlying biological abnormality in an infant facing an extrinsic risk during a critical developmental period SIDS is hypothesized to occur. Each SIDS decedent is thus thought to have a unique combination of these risk factors leading to their death. This article reviews the neuropathological literature of SIDS and uses machine learning tools to identify distinct subtypes of SIDS decedents based on epidemiological data.

Methods: We analyzed US Period Linked Birth/Infant Mortality Files from 1990 to 2017 (excluding 1992–1994). Using t-SNE, an unsupervised machine learning dimensionality reduction algorithm, we identified clusters of SIDS decedents. Following identification of these groups, we identified changes in the rates of SIDS at the state level and across three countries.

Results: Through t-SNE and distance based statistical analysis, we identified three groups of SIDS decedents, each with a unique peak age of death. Within the US, SIDS is geographically heterogeneous. Following this, we found low birth weight and normal birth weight SIDS rates have not been equally impacted by implementation of clinical guidelines. We show that across countries with different levels of cultural heterogeneity, reduction in SIDS rates has also been distinct between decedents with low vs. normal birth weight.

Conclusions: Different epidemiological and extrinsic risk factors exist based on the three unique SIDS groups we identified with t-SNE and distance based statistical measurements. Clinical guidelines have not equally impacted the groups, and normal birth weight infants comprise more of the cases of SIDS even though low birth weight infants have a higher SIDS rate.
