Inequities in adverse perinatal outcomes among Black women through the lens of maternal nativity
Black women in the United States (US) have the highest risk of adverse perinatal outcomes, including preterm birth (PTB) and small for gestational age (SGA) birth, compared to women from all other race/ethnicities. Past research using samples of Black women living on the East Coast of the US has found variation in this risk by maternal nativity status, wherein foreign-born Black women are known to have a lower risk of adverse perinatal outcomes than US-born Black women. There is a paucity of research that contextualizes the rates of adverse perinatal outcomes among Black women through the lens of maternal nativity. This is particularly true for women on the West Coast of the US, where the immigrant ethnic composition is primarily African-born, compared to the largely Caribbean-born population on the East Coast. This dissertation utilizes all birth certificate and hospitalization data for singleton non-anomalous live-births to US- and African-born Black women in California from 2011-2020 to conduct three population-based studies examining the rates of PTB and SGA through the lens of maternal nativity, while exploring how African country of origin, exposure to neighborhood-level structural racism, and clinical factors may help to contextualize previously established nativity-based disparities.In the first chapter, births to all African-born Black women are stratified by African country of origin and compared to the overall rate of adverse perinatal outcomes among US-born Black women, to determine whether the lower risk of adverse outcomes is uniform across all African countries of origin. We also evaluate whether differences in socio-demographic and clinical risk factors explain the overall disparities in PTB and SGA risk between US- and African-born Black women. We found heterogeneity in the risk of adverse birth outcomes among the African-born population, as Cameroon- and Eritrea-born Black women had larger differences, while Ghana-born Black women had smaller differences compared to US-born Black women. Overall, differences in socio-demographic and clinical risk factors between US- and African-born Black women explained a modest proportion of the nativity-based disparities in PTB (14.4%) and SGA (19.6%), although these proportions varied across African countries of origin.In the second chapter, the aforementioned California birth data were merged with information from the American Community Survey to compute neighborhood-level measures of structural racism, operationalized as racial and economic neighborhood segregation. We assess the relationship between structural racism, maternal nativity, and adverse perinatal outcomes, finding that on average US-born Black women had an 81% greater risk of PTB and a 67% greater risk of SGA, compared to African-born Black women. US-born Black women were also more likely to live in areas with more structural racism than African-born Black women. Structural racism was associated with an increased risk of PTB and SGA for all Black women, however there was variation of this effect by maternal nativity.In the third chapter, we focus on data pertaining to pregnancy and postpartum co-morbidities as well as clinical procedures within our dataset to assess the relationship between 14 clinical factors and the risk of PTB and SGA by maternal nativity. We found that on average US-born Black women had a higher prevalence of clinical factors associated with adverse perinatal outcomes. However, among African-born Black women the clinical risk factors conferred a heightened risk of PTB and SGA compared to US-born Black women, and therefore differences in the impact of these of clinical factors likely does not explain the heightened risk of PTB and SGA among US-born Black women. Taken together, these findings emphasize the importance of considering maternal nativity when analyzing adverse perinatal outcome data for Black women. Analyses in California showed that nativity in Black women considered as an aggregate may mask heterogeneity in the risk of PTB and SGA. Future studies should continue to explore differences in the experience of racism across the life course as a core driver of inequities in adverse perinatal outcomes among Black women
Structural racism is associated with adverse postnatal outcomes among Black preterm infants.
BackgroundStructural racism contributes to racial disparities in adverse perinatal outcomes. We sought to determine if structural racism is associated with adverse outcomes among Black preterm infants postnatally.MethodsObservational cohort study of 13,321 Black birthing people who delivered preterm (gestational age 22-36 weeks) in California in 2011-2017 using a statewide birth cohort database and the American Community Survey. Racial and income segregation was quantified by the Index of Concentration at the Extremes (ICE) scores. Multivariable generalized estimating equations regression models were fit to test the association between ICE scores and adverse postnatal outcomes: frequent acute care visits, readmissions, and pre- and post-discharge death, adjusting for infant and birthing person characteristics and social factors.ResultsBlack birthing people who delivered preterm in the least privileged ICE tertiles were more likely to have infants who experienced frequent acute care visits (crude risk ratio [cRR] 1.3 95% CI 1.2-1.4), readmissions (cRR 1.1 95% CI 1.0-1.2), and post-discharge death (cRR 1.9 95% CI 1.2-3.1) in their first year compared to those in the privileged tertile. Results did not differ significantly after adjusting for infant or birthing person characteristics.ConclusionStructural racism contributes to adverse outcomes for Black preterm infants after hospital discharge.Impact statementStructural racism, measured by racial and income segregation, was associated with adverse postnatal outcomes among Black preterm infants including frequent acute care visits, rehospitalizations, and death after hospital discharge. This study extends our understanding of the impact of structural racism on the health of Black preterm infants beyond the perinatal period and provides reinforcement to the concept of structural racism contributing to racial disparities in poor postnatal outcomes for preterm infants. Identifying structural racism as a primary cause of racial disparities in the postnatal period is necessary to prioritize and implement appropriate structural interventions to improve outcomes

Neighborhood Income Is Associated with Health Care Use in Pediatric Short Bowel Syndrome
ObjectiveTo evaluate associations between neighborhood income and burden of hospitalizations for children with short bowel syndrome (SBS).Study designWe used the Pediatric Health Information System (PHIS) database to evaluate associations between neighborhood income and hospital readmissions, readmissions for central line-associated bloodstream infections (CLABSI), and hospital length of stay (LOS) for patients <18 years with SBS hospitalized between January 1, 2006, and October 1, 2015. We analyzed readmissions with recurrent event analysis and analyzed LOS with linear mixed effects modeling. We used a conceptual model to guide our multivariable analyses, adjusting for race, ethnicity, and insurance status.ResultsWe included 4289 children with 16 347 hospitalizations from 43 institutions. Fifty-seven percent of the children were male, 21% were Black, 19% were Hispanic, and 67% had public insurance. In univariable analysis, children from low-income neighborhoods had a 38% increased risk for all-cause hospitalizations (rate ratio [RR] 1.38, 95% CI 1.10-1.72, P = .01), an 83% increased risk for CLABSI hospitalizations (RR 1.83, 95% CI 1.37-2.44, P < .001), and increased hospital LOS (β 0.15, 95% CI 0.01-0.29, P = .04). In multivariable analysis, the association between low-income neighborhoods and elevated risk for CLABSI hospitalizations persisted (RR 1.70, 95% CI 1.23-2.35, P < .01, respectively).ConclusionsChildren with SBS from low-income neighborhoods are at increased risk for hospitalizations due to CLABSI. Examination of specific household- and neighborhood-level factors contributing to this disparity may inform equity-based interventions

“It was just one moment that I felt like I was being judged”: Pregnant and postpartum black Women's experiences of personal and group-based racism during the COVID-19 pandemic
BackgroundRacial inequities in maternal and child health outcomes persist: Black women and birthing people experience higher rates of adverse outcomes than their white counterparts. Similar inequities are seen in coronavirus disease (COVID-19) mortality rates. In response, we sought to explore the intersections of racism and the COVID-19 pandemic impact on the daily lives and perinatal care experiences of Black birthing people.MethodsWe used an intrinsic case study approach grounded in an intersectional lens to collect stories from Black pregnant and postpartum people residing in Fresno County (July-September 2020). All interviews were conducted on Zoom without video and were audio recorded and transcribed. Thematic analysis was used to group codes into larger themes.ResultsOf the 34 participants included in this analysis, 76.5% identified as Black only, and 23.5% identified as multiracial including Black. Their mean age was 27.2 years [SD, 5.8]. Nearly half (47%) reported being married or living with their partner; all were eligible for Medi-Cal insurance. Interview times ranged from 23 to 96 min. Five themes emerged: (1) Tensions about Heightened Exposure of Black Lives Matter Movement during the pandemic; (2) Fear for Black Son's Safety; (3) Lack of Communication from Health Care Professionals; (4) Disrespect from Health Care Professionals; and (5) Misunderstood or Judged by Health Care Professionals. Participants stressed that the Black Lives Matter Movement is necessary and highlighted that society views their Black sons as a threat. They also reported experiencing unfair treatment and harassment while seeking perinatal care.ConclusionsBlack women and birthing people shared that exposure to racism has heightened during the COVID-19 pandemic, increasing their levels of stress and anxiety. Understanding how racism impacts Black birthing people's lives and care experiences is critical to reforming the police force and revising enhanced prenatal care models to better address their needs

Mortality and Major Neonatal Morbidity in Preterm Infants with Serious Congenital Heart Disease.
OBJECTIVE: To investigate the trends of 1-year mortality and neonatal morbidities in preterm infants with serious congenital heart disease (CHD). STUDY DESIGN: This cohort study used a population-based administrative dataset of all liveborn infants of 26-36 weeks gestational age with serious CHD born in California between 2011 and 2017. We assessed 1-year mortality and major neonatal morbidities (ie, retinopathy of prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage grade >2, and periventricular leukomalacia) across the study period and compared these outcomes with those in infants without CHD. RESULTS: We identified 1921 preterm infants with serious CHD. The relative risk (RR) of death decreased by 10.6% for each year of the study period (RR, 0.89; 95% CI, 0.84-0.95), and the RR of major neonatal morbidity increased by 8.3% for each year (RR, 1.08; 95% CI, 1.02-1.15). Compared with preterm neonates without any CHD (n = 234 522), the adjusted risk difference (ARD) for mortality was highest at 32 weeks of gestational age (9.7%; 95% CI, 8.3%-11.2%), that for major neonatal morbidity was highest at 28 weeks (21.9%; 95% CI, 17.0%-26.9%), and that for the combined outcome was highest at 30 weeks (26.7%; 95% CI, 23.3%-30.1%). CONCLUSIONS: Mortality in preterm neonates with serious CHD decreased over the last decade, whereas major neonatal morbidities increased. Preterm infants with a gestational age of 28-32 weeks have the highest mortality or morbidity compared with their peers without CHD. These results support the need for specialized and focused medical neonatal care in preterm neonates with serious CHD
Maternal nativity and risk of adverse perinatal outcomes among Black women residing in California, 2011-2017.
ObjectiveExamine the risk of adverse perinatal outcomes among the United States (US)-born and foreign-born Black women in California.Study designThe study comprised all singleton live births to Black women in California between 2011 and 2017. We defined maternal nativity as US-born or foreign-born. Using Poisson regression, we computed risk ratios (RR) and 95% confidence intervals (CI) for three adverse perinatal outcomes: preterm birth, small for gestational age deliveries, and infant mortality.ResultsRates of adverse perinatal outcomes were significantly higher among US-born Black women. In adjusted models, US-born Black women experienced an increased risk of preterm birth (RR 1.51, 95% CI 1.39, 1.65) and small for gestational age deliveries (RR 1.52, 95% CI 1.41, 1.64), compared to foreign-born Black women.ConclusionsFuture studies should consider experiences of racism across the life course when exploring heterogeneity in the risk of adverse perinatal outcomes by nativity among Black women in the US
Clinicians' Perspectives on Racism and Black Women's Maternal Health.
ObjectiveThe objective of this study was to explore clinician perceptions of how racism affects Black women's pregnancy experiences, perinatal care, and birth outcomes.Materials and methodsWe conducted 25 semi-structured interviews with perinatal care clinicians practicing in the San Francisco Bay Area (January to March 2019) who serve racially diverse women. Participants were primarily recruited through "Dear Perinatal Care Provider" email correspondences sent through department listservs. Culturally concordant, qualitatively trained research assistants conducted all interviews in person. The interviews ranged from 30 to 60 minutes and were audio-recorded and professionally transcribed verbatim. We used the constant comparative method consistent with grounded theory to analyze data.ResultsMost participants were obstetrician/gynecologists (n = 11, 44%) or certified nurse midwives (n = 8, 32%), had worked in their current role for 1 to 5 years (n = 10, 40%), and identified as white (n = 16, 64%). Three themes emerged from the interviews: provision of inequitable care (e.g., I had a woman who had a massive complication during her labor course and felt like she wasn't being treated seriously); surveillance of Black women and families (e.g., A urine tox screen on the Black baby even though it was not indicated, and they didn't do it on the white baby when, in fact, it was indicated); and structural care issues (e.g., the history of medical racial experimentation).ConclusionClinicians' views about how racism is currently operating and negatively impacting Black women's care experiences, health outcomes, and well-being in medical institutions will be used to develop a racial equity training for perinatal care clinicians in collaboration with Black women and clinicians
Psychometric validation of a patient‐reported experience measure of obstetric racism© (The PREM‐OB Scale™ suite)
BackgroundPerinatal quality improvement lacks valid tools to measure adverse hospital experiences disproportionately impacting Black mothers and birthing people. Measuring and mitigating harm requires using a framework that centers the lived experiences of Black birthing people in evaluating inequitable care, namely, obstetric racism. We sought to develop a valid patient-reported experience measure (PREM) of Obstetric Racism© in hospital-based intrapartum care designed for, by, and with Black women as patient, community, and content experts.MethodsPROMIS© instrument development standards adapted with cultural rigor methodology. Phase 1 included item pool generation, modified Delphi method, and cognitive interviews. Phase 2 evaluated the item pool using factor analysis and item response theory.ResultsItems were identified or written to cover 7 previously identified theoretical domains. 806 Black mothers and birthing people completed the pilot test. Factor analysis concluded a 3 factor structure with good fit indices (CFI = 0.931-0.977, RMSEA = 0.087-0.10, R2 > .3, residual correlation < 0.15). All items in each factor fit the IRT model and were able to be calibrated. Factor 1, "Humanity," had 31 items measuring experiences of safety and accountability, autonomy, communication, and empathy. A 12-item short form was created to ease respondent burden. Factor 2, "Racism," had 12 items measuring experiences of neglect and mistreatment. Factor 3, "Kinship," had 7 items measuring hospital denial and disruption of relationships between Black mothers and their child or support system.ConclusionsThe PREM-OB Scale™ suite is a valid tool to characterize and quantify obstetric racism for use in perinatal improvement initiatives
Risk and Protective Factors for Preterm Birth Among Black Women in Oakland, California.
This project examines risk and protective factors for preterm birth (PTB) among Black women in Oakland, California. Women with singleton births in 2011-2017 (n = 6199) were included. Risk and protective factors for PTB and independent risk groups were identified using logistic regression and recursive partitioning. Having less than 3 prenatal care visits was associated with highest PTB risk. Hypertension (preexisting, gestational), previous PTB, and unknown Women, Infant, Children (WIC) program participation were associated with a two-fold increased risk for PTB. Maternal birth outside of the USA and participation in WIC were protective. Broad differences in rates, risks, and protective factors for PTB were observed
Racial disparities in emergency mental healthcare utilization among birthing people with preterm infants.
BackgroundBirthing people of color are more likely to deliver low birthweight and preterm infants, populations at significant risk of morbidity and mortality. Birthing people of color are also at higher risk for mental health conditions and emergency mental healthcare utilization postpartum. Although this group has been identified as high risk in these contexts, it is not known whether racial and ethnic disparities exist in mental healthcare utilization among birthing people who have delivered preterm.ObjectiveWe sought to determine if racial and ethnic disparities exist in postpartum mental healthcare-associated emergency department visits or hospitalizations for birthing people with preterm infants in a large and diverse population.Study designThis population-based historic cohort study used a sample of Californian live-born infants born between 2011 and 2017 with linked birth certificates and emergency department visit and hospital admission records from the California Statewide Health Planning and Development database. The sample was restricted to preterm infants (<37 weeks' gestation). Self-reported race and ethnicity groups included Hispanic, non-Hispanic Black, non-Hispanic Asian, non-Hispanic White, and non-Hispanic others. Mental health diagnoses were identified from the International Classification of Diseases Ninth and Tenth revision codes recorded in emergency department and hospital discharge records. Logistic regression analysis was used to estimate the association between mental health-related emergency department visits and rehospitalizations by race or ethnicity compared with non-Hispanic White birthing people and controlling for the following characteristics and health condition covariates: age, parity, previous preterm birth, body mass index, smoking, alcohol use, hypertension, diabetes, previous mental health diagnosis, and prenatal care.ResultsOf 204,539 birthing people who delivered preterm infants in California, 1982 visited the emergency department and 836 were hospitalized in the first year after preterm birth for a mental health-related illness. Black birthing people were more likely to have a mental health-related emergency department visit and hospitalization (risk ratio, 1.8; 95% confidence interval, 1.5-2.0 and risk ratio, 1.9; 95% confidence interval, 1.5-2.3, respectively) within the first postpartum year than White birthing people. Hispanic and Asian birthing people were less likely to have mental health-related emergency department visits (adjusted risk ratio, 0.7; 95% confidence interval, 0.7-0.8 and adjusted risk ratio, 0.2; 95% confidence interval, 0.2-0.3, respectively) and hospitalizations (adjusted risk ratio, 0.6; 95% confidence interval, 0.5-0.7 and adjusted risk ratio, 0.2; 95% confidence interval, 0.1-0.3, respectively). When controlling for birthing people with a previous mental health diagnosis and those without, the disparities remained the same.ConclusionRacial and ethnic disparities exist in emergency mental healthcare escalation among birthing people who have delivered preterm infants. Our findings highlight a need for further investigation into disparate mental health conditions, exacerbations, access to care, and targeted hospital and legislative policies to prevent emergency mental healthcare escalation and reduce disparities
