Associations Among Racial Discrimination, Perceived Stress, and Birth Satisfaction in Black Women in the Postpartum Period.

OBJECTIVE: To examine associations among experiences of racial discrimination, perceived stress, and birth satisfaction and to test if perceived stress mediates the relationship between racial discrimination and birth satisfaction among Black women in the postpartum period. DESIGN: Secondary analysis of data from the Biosocial Impact on Black Births study. SETTING: A postpartum unit of a large hospital in Central Florida. PARTICIPANTS: Black women (N = 155) in the postpartum period. METHODS: Participants completed the lifetime Experiences of Discrimination scale, Perceived Stress Scale and Birth Satisfaction Scale-Revised between 24 hours and 23 days after birth. We calculated descriptive statistics and Spearman's ρ correlation coefficients to evaluate associations among variables. We used multiple linear regression to evaluate perceived stress as a mediator between racial discrimination and birth satisfaction. RESULTS: Racial discrimination had a positive association with perceived stress (ß = 2.445, p = .03), and perceived stress had a negative association with birth satisfaction (ß = -0.221, p = .02). Racial discrimination had no significant direct effect on birth satisfaction (ß = -0.091, p = .94); therefore, perceived stress did not mediate the relationship. CONCLUSION: More experiences of discrimination over the life span were associated with higher levels of perceived stress. Participants who reported higher levels of perceived stress reported lower levels of birth satisfaction. Our study adds to the body of knowledge regarding associations between racial discrimination and perceived stress and perceived stress and birth satisfaction.

Racial Discrimination, Social Support, and Psychological Distress Among Black Pregnant Women.

BACKGROUND: Black pregnant women who experience racial discrimination are at an increased risk of psychological distress. Studies have not adequately addressed if social support may moderate the association between experiences of racial discrimination and psychological distress among Black pregnant women. OBJECTIVE: We sought to examine the moderating effect of social support on the association between experiences of racial discrimination and psychological distress among Black pregnant women. METHODS: We report findings based on cross-sectional data collected from 599 Black pregnant women enrolled in a prospective cohort study prior to the COVID-19 pandemic. Women completed questionnaires about experiences of racial discrimination (Experiences of Discrimination), social support (MOS Social Support Survey), and psychological distress (Psychological General Wellbeing Index). RESULTS: Women had an average age of 26 ± 5 years and gestational age at data collection of 17 ± 6 weeks. Approximately 53% of women reported ever experiencing racial discrimination in at least one situation, and 54% reported psychological distress. After adjustment for covariates, racial discrimination was associated with a 2.2-fold increase in psychological distress (odds ratio [OR] = 2.24; 95% confidence interval [CI] 1.35-3.70; P = .002). Low social support (scores below the median) was associated with a 3.8-fold higher likelihood of psychological distress (OR = 3.84, 95% CI 2.27-6.48, P < .001). Social support did not moderate the association of lifetime experiences of racial discrimination with psychological distress. CONCLUSIONS: Findings of the study contribute to evidence that lifetime experiences of racial discrimination and low levels of social support relate to psychological distress among Black pregnant women.

A Mixed Methods Approach to Understand Mother-Father Relationship and Perceived Stress Among Black Pregnant Women.

BACKGROUND: Black women in the United States report moderate to high levels of perceived stress during pregnancy. Though lower levels of involvement and support from father of the baby (FOB) and higher levels of conflict have been associated with higher levels of maternal perceived stress, it is not clear how Black pregnant women experience the mother-father relationship and its influence on perceived stress. PURPOSE: To examine and describe the mother-father relationship and its role in experiences of perceived stress from the perspective of Black pregnant women. METHODS: Using a convergent, mixed methods approach with ideal-type analysis, we conducted a secondary analysis of data among 60 Black pregnant women enrolled in the Biosocial Impact on Black Births study. Women completed online self-report questionnaires and participated in a semi-structured interview by telephone. RESULTS: Participants who reported more conflict with FOB also reported higher levels of perceived stress (ρ(47) = .431, P= .002). Themes (importance, communication, support, conflict, satisfaction, and stress) emerged from the data. Five distinct mother-father relationship typologies were identified following an ideal-type analysis of the combined dataset: Cared For; Managing Expectations; Just Friends, For the Kids; It's Complicated; and Can't be Bothered. CONCLUSIONS: These findings are an innovative exemplar of ideal-type analysis and provide a deeper understanding of the nuance and dynamics within the mother-father relationship and how it influences perceived stress among Black pregnant women. IMPLICATIONS: Clinicians must recognize the significance of the mother-father relationship and, when appropriate, encourage paternal involvement or intervene if there is conflict during pregnancy.

Neighborhood Environment and Perceived Stress Before and During the COVID-19 Pandemic Among Childbearing Black Women.

PURPOSE: The purpose of this study among pregnant and postpartum Black women was twofold: (1) to compare levels of perceived stress, depressive symptoms, social support, and neighborhood disorder and crime before the pandemic vs during the pandemic; and (2) to examine the association of perceived stress, depressive symptoms, and social support with neighborhood disorder and crime at both time points. METHODS: This was a prospective study as part of the Biosocial Impact on Black Births, a longitudinal study that examined the role of maternal factors on preterm birth among Black women. A sample of 143 women were included who responded to survey questions during pregnancy prior to the pandemic and again after birth, during the pandemic. Women completed the COVID survey between May 21, 2020, and January 28, 2021. RESULTS: The levels of perceived stress (70.75 and 76.28, respectively, P < .01) and social support (17.01 and 18.78, respectively, P < .01) were lower during the pandemic than prior to the pandemic. Social support, perceived stress, and depressive symptoms were significantly correlated with the pre-pandemic measures of perceived neighborhood disorder and crime. Perceived stress and depressive symptoms were also significantly correlated with pandemic measures of perceived neighborhood. CONCLUSION: Women reported lower levels of perceived stress during the pandemic than prior to the pandemic, but neighborhood characteristics were consistently associated with perceived stress and depressive symptoms both prior to and during the pandemic. Further exploration is warranted to better understand these relationships.

Changes in Lipid Profiles with the Progression of Pregnancy in Black Women.

Background/Objectives: Lipid metabolism plays an important role in maternal health and fetal development. There is a gap in the knowledge of how lipid metabolism changes during pregnancy for Black women who are at a higher risk of adverse outcomes. We hypothesized that the comprehensive lipidome profiles would show variation across pregnancy indicative of requirements during gestation and fetal development. Methods: Black women were recruited at prenatal clinics. Plasma samples were collected at 8-18 weeks (T1), 22-29 weeks (T2), and 30-36 weeks (T3) of pregnancy. Samples from 64 women who had term births (≥37 weeks gestation) were subjected to "shotgun" Orbitrap mass spectrometry. Mixed-effects models were used to quantify systematic changes and dimensionality reduction models were used to visualize patterns and identify reliable lipid signatures. Results: Total lipids and major lipid classes showed significant increases with the progression of pregnancy. Phospholipids and glycerolipids exhibited a gradual increase from T1 to T2 to T3, while sphingolipids and total sterol lipids displayed a more pronounced increase from T2 to T3. Acylcarnitines, hydroxy acylcarnitines, and Lyso phospholipid levels significantly decreased from T1 to T3. A deviation was that non-esterified fatty acids decreased from T1 to T2 and increased again from T2 to T3, suggestive of a potential role for these lipids during the later stages of pregnancy. The fatty acids showing this trend included key fatty acids-non-esterified Linoleic acid, Arachidonic acid, Alpha-linolenic acid, Eicosapentaenoic acid, Docosapentaenoic acid, and Docosahexaenoic acid. Conclusions: Mapping lipid patterns and identifying lipid signatures would help develop intervention strategies to reduce perinatal health disparities among pregnant Black women.

Pilot Study of the FitMoms2B Physical Activity Promotion Program Among Black Women With High-Risk Pregnancies.

OBJECTIVE: To explore the feasibility of recruitment, adherence, and retention and the acceptability of the FitMoms2B physical activity promotion program and study measures among non-Hispanic Black women with high-risk pregnancies. DESIGN: One-arm pilot feasibility study. SETTING: A large regional high-risk prenatal clinic in the southeastern United States. PARTICIPANTS: Non-Hispanic Black women who had singleton, high-risk pregnancies at 16 to 23 weeks gestation with no contraindications to physical activity (N = 13). METHOD: We evaluated the feasibility and acceptability of a multicomponent intervention, which included physical activity coaching, support from a workout partner, and an activity tracker. We also assessed the feasibility of study measures for future trials of the program. RESULTS: Of 179 patients screened, 20 were eligible, and 13 consented and enrolled (65%). Of the 13 participants, 9 completed data collection at Time Point (T) 1 (16-23 weeks gestation) and T2 (24-30 weeks), and 8 completed data collection at T3 (31 or more weeks). Adherence met expectations for coaching (63%), exercise with a workout partner (100%), and use of the activity tracker (92%). Acceptability was high (100%). CONCLUSION: We found that recruitment, retention, and adherence are feasible for the FitMoms2B physical activity promotion program. The program and study measures were acceptable to participants in our sample. We provide preliminary support for a randomized controlled trial to study physical activity promotion with virtual coaching, workout partner support, and activity tracking among Black pregnant women with high-risk pregnancies without contraindications to physical activity.

Neighborhood racial composition and experiences of racial discrimination: Associations with cytokines during pregnancy among African American women.

Background: Preterm birth rates are consistently higher in African American (AA) pregnancies compared to White pregnancies in the United States. Neighborhood racial composition, experiences of racial discrimination, and systemic inflammation are factors that have been associated with preterm birth and other adverse pregnancy outcomes that may account for these disparities. Here, we investigated whether perceived neighborhood racial composition and experiences of discrimination were predictive of cytokine levels during pregnancy among AA individuals. Methods: 545 AA individuals completed surveys and had blood samples collected at prenatal clinics in the Midwest at three timepoints (8-18,19-29, and 30-36 weeks gestation) throughout pregnancy. Pro-inflammatory [interferon (IFN)-γ, interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-α, macrophage migration inhibitory factor (MIF)] and anti-inflammatory cytokines (IL-10) were quantified. Multivariate and multilevel models were used to examine associations of perceived neighborhood racial composition and experiences of racial discrimination with cytokine levels, controlling for relevant covariates. Results: Perceived neighborhood racial composition was significantly associated with MIF at 30-36 weeks gestation in multivariate regression (p < 0.001). Living in neighborhoods with more compared to fewer White people was predictive of higher levels of MIF (b = 0.599, SE = 0.12, p < 0.001). Experiences of discrimination were also associated with higher levels of MIF (ß = 0.141, SE = 0.07, p = 0.036). Neither predictor was associated with other cytokines. Follow-up analyses revealed that neighborhood racial composition was also predictive of higher MIF levels at 8-18 weeks gestation (p = 0.02) and at 19-29 weeks gestation (p = 0.04). Conclusions: Living in neighborhoods with more White individuals and having more lifetime experiences of racial discrimination were positively related to levels of the pro-inflammatory cytokine, MIF, among pregnant AA individuals. MIF's known positive relationships with chronic stress and preterm birth suggest that these elevations in MIF may have negative health consequences. Future studies should explore whether MIF serves as a pathway between neighborhood racial composition or experiences of racial discrimination and preterm birth risk among AA individuals.

Vitamin D Status as an Important Predictor of Preterm Birth in a Cohort of Black Women.

Vitamin D deficiency (25 (OH)D < 20 ng/mL) is a modifiable risk factor that has been associated with an increased risk of preterm birth (PTB) (<37 weeks gestation). Black women are at a high risk for vitamin D deficiency due to higher melanin levels. Vitamin D sufficiency may be protective against PTB risk in Black women. Black participants between 8 and 25 weeks of gestation were included in this nested case-control study. The sample consisted of women who had either PTBs (n = 57) or term births, were selected based on maternal age compared to those who had PTBs (n = 118), and had blood samples available between 8 and 25 weeks of gestation. The women completed questionnaires about depressive symptoms and smoking behavior and had blood collected to determine their vitamin D levels. Gestational age at birth, hypertensive disorders, and body mass index (BMI) were collected from the medical records. The odds of PTB were increased by 3.34 times for participants with vitamin D deficiency after adjusting for hypertensive disorders of pregnancy and depressive symptoms. Vitamin D assessment and supplementation may be an important intervention for preventing PTB in pregnant Black women.

Mother-Father Relationship and Depressive Symptoms Among Pregnant Black Women.

BACKGROUND: Black women report higher levels of depressive symptoms during pregnancy than white women. A supportive relationship with the father of the baby may be protective and decrease depressive symptoms. OBJECTIVE: We sought to examine the association between mother-father relationship and depressive symptoms among pregnant black women. METHODS: Using a cross-sectional design, we conducted a secondary data analysis from a subsample of 405 pregnant black women who participated in the Biosocial Impact on Black Births study, a prospective cohort study. Participants completed questionnaires at 19- to 29-week gestation, including 6 measures of their relationship with the father of the baby: (1) contact, (2) involvement, (3) overall relationship, (4) change in relationship from prior to pregnancy to during pregnancy, (5) support, and (6) conflict. Latent class analysis was used to identify and classify the relationship construct. The Center for Epidemiologic Studies-Depression (CES-D) scale was used, with scores ≥23 considered high levels of depressive symptoms. Data were analyzed with logistic regression. RESULTS: Following adjustment for maternal sociodemographic characteristics, comorbid conditions, and health behaviors, women in a conflictual relationship had higher odds of having depressive symptom scores ≥23 (adjusted odds ratio: 3.50, 95% confidence interval: 2.00, 6.12) than those having no relationship (adjusted odds ratio: 2.81, 95% confidence interval: 1.43, 5.52), when compared with those with a good relationship. CONCLUSIONS: These findings suggest that having either a conflictual or no relationship with the father of the baby during pregnancy increases the odds for higher maternal depressive symptoms (CES-D scores ≥ 23) among pregnant black women.

Fathers Matter: Black Fathers' Relationships with their Partners during Pregnancy and Postpartum.

PURPOSE: To describe the characteristics of participants in the Fathers Matter study for a better understanding of fathers of the baby who engage in pregnancy research involving primarily Black couples and their relationships with their partners. STUDY DESIGN AND METHODS: The Fathers Matter Study uses a prospective design, identifying father-mother dyads during pregnancy and following them until birth as part of the Biosocial Impacts on Black Births Study. Participants completed prenatal and postpartum questionnaires. RESULTS: Our analyses are based on 111 fathers. Nearly all ( n = 101, 91.1%) of fathers identified as Black and 51.4% ( n = 57) had a high school diploma, graduate equivalency diploma, or higher. About half ( n = 57, 51.4%) reported annual incomes of $10,000 or less. Most reported that relationships with the mother were very close both before ( n = 100, 89.9%) and during ( n = 85, 76.6%) pregnancy. However, substantial variability was found in relationship satisfaction, involvement in the pregnancy, financial support provided, and scales of conflict and support. CLINICAL IMPLICATIONS: We found homogeneity in sociodemographic and basic relationship measures. Complex measures of the father-mother relationships demonstrated considerable variability. Data from fathers may identify their contributions to successful birth outcomes. Understanding relationships between fathers and mothers could identify risk or protective characteristics to be addressed at the family or community levels.

Epigenetic Implications of Neighborhood Disorder and Psychological Distress among Pregnant Black Women.

Background: In the United States, Black women experience preterm birth (PTB; <37 weeks gestation) at more than 1.5 times the rate of non-Hispanic White women. Social determinants of health including the neighborhood environment have been recognized as contributing to the risk of PTB. Due to historical segregation, Black women are more likely to live in neighborhoods with higher levels of neighborhood disorder compared with White women. Perceived neighborhood disorder appears to be a risk factor for maternal psychological distress in Black women and psychological distress has mediated the association between neighborhood disorder and the risk for PTB. However, the biological pathways underpinning these associations are not clear. Objective: We examined the associations among neighborhood disorder; psychological distress; DNA methylation of six stress-related, glucocorticoid candidate genes (AVP, CRH, CRHBP, FKBP5, HSD11B2, NR3C1); and gestational age at birth among 44 Black pregnant women. Methods: Women who were 18-45 years old and 8-18 weeks gestation had blood drawn and completed questionnaires measuring perceived neighborhood disorder, neighborhood crime, and psychological distress. Results: Three CpG sites were associated with neighborhood disorder (cg03405789 [CRH], cg14939152 and cg15910486 [NR3C1]). One CpG site, cg03098337 (FKBP5) was associated with psychological distress. Three of the identified CpG sites were located within gene CpG islands or shores-areas at which DNA methylation is known to affect gene transcription. Conclusion: These findings warrant further research to clarify intermediate biological pathways and potential biomarkers to identify women at risk for PTB. Identification of PTB risk early in pregnancy would allow for interventions to prevent PTB.

A mixed methods systematic review of midwives' clinical practices related to prenatal care of women with obesity.

OBJECTIVE: Maternal obesity has been related to adverse maternal and infant outcomes. It is a persistent challenge of midwifery care worldwide and can present clinical challenges and complications. This review sought to identify evidence on the practice patterns of midwives related to prenatal care of women with obesity. METHODS: The databases Academic Search Premier, APA PsycInfo, CINAHL PLUS with Full Text, Health Source: Nursing/Academic Edition, and MEDLINE were searched November 2021. Search terms included weight, obesity, practices, and midwives. Inclusion criteria included quantitative, qualitative, and mixed method studies that addressed practice patterns of midwives related to prenatal care of women with obesity published in peer-reviewed journals, written in English. The recommended Joanna Briggs Institute approach to mixed methods systematic reviews was followed e.g. study selection, critical appraisal, data extraction, and a convergent segregated method of data synthesis and integration. RESULTS: Seventeen articles from 16 studies were included. The quantitative evidence showed a lack of knowledge, confidence, and support for midwives that would facilitate adequate management of pregnant women with obesity while the qualitative evidence revealed that midwives desire a sensitive approach to discussing obesity and the risks associated with maternal obesity. DISCUSSION: Quantitative and qualitative literature report consistent individual and system-level barriers to implementing evidence-based practices. Implicit bias training, midwifery curriculum updates, and the use of patient centered care models may help overcome these challenges.

The associations of objective and perceived neighborhood disadvantage with stress among pregnant black women.

BACKGROUND: Neighborhood disadvantage may impact risk of preterm birth through stress. Few studies have examined how neighborhood disadvantage relates to stress during pregnancy, especially for Black women. METHODS: Secondary data analysis of 572 women in a prospective cohort in Detroit, MI and Columbus, OH. Participants completed questionnaires including the ROSS Neighborhood Disorder Scale, the crime subscale of the Perceived Neighborhood Scale (PNS), and the Perceived Stress Scale. An objective neighborhood disadvantage index (NDI) was created using principal components analysis after geocoding residential addresses and linking to Census data. RESULTS: All models used logistic regression. Adjusted for maternal age and annual household income, perceived stress was positively associated with perceived neighborhood disorder (p < .01). In a separate model, perceived neighborhood crime was positively associated with perceived neighborhood disorder (p = .005). In a joint model adjusted for age and income, the association of disorder with stress was similar in magnitude (p < .01) but the association between crime and stress weakened. The NDI was not associated with perceived stress before or after adjustment for confounders. CONCLUSIONS: Perceived neighborhood disadvantage may capture a different dimension than objective neighborhood disadvantage. Future studies should test stress as a pathway by which neighborhood environment increases risk of preterm birth.

Primary care nurse practitioner practices to lower type 2 diabetes risks in women with a history of gestational diabetes mellitus.

BACKGROUND: Women with a gestational diabetes mellitus (GDM) history have increased lifetime type 2 diabetes (T2D) risk, with 16 times greater risk 3 to 6 years after the pregnancy, compared with women without GDM. Offspring from diabetes-complicated pregnancies also face increased health risks. PURPOSE: The study purpose was to describe the primary care practices of nurse practitioners (NPs) aimed at reducing T2D-related health risks in women with a history of GDM. METHODOLOGY: Florida-licensed primary care NPs (n = 47) completed a 57-item online survey that included an 8-item scale about recommended practices to reduce T2D risks for women with GDM history. Descriptive statistics, Chi Square test, and Fisher exact test were conducted. RESULTS: Most (67%) participants "often/always" screened for T2D every 1-3 years per guidelines, but only 31.8% "often/always" advised about pregnancy planning/preconception T2D assessment. Compared with "none" or ≤2 hours of GDM care education, participants with >2 hours were more likely (p < .05) to "often/always" perform five recommended practices: 1) counsel about increased T2D risks; 2) educate about self-advocacy for T2D screening; 3) T2D screening every 1-3 years; 4) counsel about breastfeeding to reduce T2D risk; and 5) discuss postpartum weight loss and increased physical activity to lower T2D risk. CONCLUSION: Findings indicate inconsistent care practices and suggest that >2 hours of education about care of women with GDM history may increase primary care NPs performing recommended practices to reduce T2D risks and prevent health problems for women and future offspring. IMPLICATIONS: Nurse practitioner education is needed involving care of women with GDM history to mitigate risks for T2D.

The Association of Avoidance Coping with Gestational Weight Gain among Pregnant Black Women.

Gestational weight gain (GWG) outside recommended parameters can lead to pregnancy or birth complications. Avoidance coping may influence GWG. We examined the association of avoidance coping with GWG among a sample of 112 pregnant Black women in the Midwest. Participants completed avoidance coping questionnaires at three time points throughout pregnancy. Data were abstracted from medical records for BMI and GWG. Overall, 23.2% gained inadequate weight, 30.4% adequate weight, and 46.4% excess weight. Multinomial logistic regression models indicated associations between avoidance coping and GWG adjusted for covariates. Participants with higher avoidance coping scores at 22-29 weeks' gestation were more likely to experience excess weight gain (odds ratio [OR] = 1.19, 95% CI [1.02, 1.37]). Participants with higher avoidance coping scores at 30-36 weeks' gestation were less likely to experience excess weight gain, (OR = 0.82, 95% CI [0.72, 0.93]). The impact of higher avoidance coping on excess weight gain depends on the time period in pregnancy.

Psychosocial Factors and Telomere Length Among Parents and Infants of Immigrant Arab American Families.

Background: Immigrant Arab American families face multiple stressors related to migration and resettlement. Telomere length (TL) is an established biomarker of aging and psychosocial stress. No published studies have concurrently examined the association between maternal and paternal psychosocial factors and infants' TL. The purpose of this study was to: (1) compare mother, father, and infant TLs; (2) explore the association of maternal and paternal psychosocial factors (acculturative stress and depressive symptoms) with maternal and paternal TL; and (3) explore the association of maternal and paternal psychosocial factors with infants' TL among Arab American immigrants. Method: Using a cross-sectional exploratory design, a sample of 52 immigrant Arab American mother-father-infant triads were recruited from community centers. Data were collected in a single home visit when the infant was 6-24 months old. Each parent completed the study questionnaires addressing their psychosocial factors (acculturative stress, and depressive symptoms), then parents and infants provided buccal cell for TL measurement. Results: Maternal TL was positively correlated to infants' TL (r = .31, p = .04) and significantly shorter (p < .001). Paternal TL was not correlated with infant TL but was significantly shorter than infant's TL (p < .001). Maternal depression was significantly correlated with mothers' TL (r = .4, p = .007). Higher levels of maternal depressive symptoms were significantly associated with shorter infant TL when controlling for background characteristics. Conclusions: Our pilot study is the first study to examine maternal and paternal psychosocial factors related to migration and infants' TL. More research is needed to advance our understanding of the effects of immigration on the intergenerational transfer of stress and trauma.

Association of maternal and paternal psychosocial stress and infant hair cortisol among Arab American immigrants: A pilot study.

Acculturative stress is unique among immigrants and refers to the stress associated with maintaining cultural values and traditions in the host country. Immigrant parents confront psychosocial variables such as acculturative stress, anxiety, and depression that might result in intergenerational negative consequences on their infants. Measurement of hair cortisol concentration (HCC), an outcome of neuroendocrine dysregulation, is one relatively noninvasive approach to gauge stress in infants. No published studies have evaluated associations among parents' psychosocial variables and infants' HCC among immigrant families. Therefore, the purpose of this study was to: (1) examine the relationship between maternal and paternal psychosocial stress variables; and (2) examine the association between psychosocial variables of both parents (acculturative stress, anxiety, and depression) and infants' HCC among immigrant Arab American families. A sample of 31 immigrant Arab American triads (mother-father-infant) was recruited. During one home visit, each parent completed the study questionnaires separately when the baby was 6-24 months old and a hair sample was collected from the infant for HCC. Parents reported significant symptoms of anxiety (33% mothers; 45% fathers) and depression (33% mothers; 35.5% fathers). Paternal acculturative stress, anxiety, and depressive symptoms were significantly correlated to infants' HCC. Acculturative stress, anxiety, and depressive symptoms were significantly correlated between mother-father dyads. Future research should continue to focus on immigrant families and include both parents to better understand and improve infant health.

A Qualitative Approach to the Dimensions of Segregation among Pregnant Black Women.

This study compares and contrasts residents' perceptions of segregation measures using qualitative and quantitative data. Most studies exploring racial residential segregation and health outcomes use large-scale, metropolitan-wide measures. As a result, we have limited understanding of racial residential segregation outside of Census data, particularly about the firsthand experiences of those living in segregated areas. The purpose of this study was to compare data from Census-based measures of racial residential segregation with qualitative descriptions of these same constructs by pregnant, Black women in two US cities. Using novel qualitative interview questions, we explored the dimensions of segregation and neighborhood racial distribution among a sample of 27 pregnant, Black women between April and November 2019. The participants included in this sample had perceptions about their neighborhood segregation and demographic composition that were often different from the data derived from existing residential US Census data. The differences between qualitative and quantitative measures and the possible reasons for the discordance suggest new approaches to measurement and new directions for the study of segregation and health.

DNA Methylation Patterns of Glucocorticoid Pathway Genes in Preterm Birth Among Black Women.

Preterm birth (PTB; <37 weeks gestation) rates have increased for 5 of the last 6 consecutive years in the United States. These rates are particularly alarming for U.S. non-Hispanic Black women who give birth prematurely at 1.5 times the rate of non-Hispanic White women. Previous research suggests that psychological stress is associated with PTB in Black women. However, the biological pathways by which stress alters birth timing are not clear. We examined DNA methylation (DNAm) in peripheral blood leukocytes in 6 glucocorticoid, stress-related genes in 44 (22 PTB; 22 term birth) pregnant Black women. Four cytosine-phosphate-guanine (CpG) sites were identified as differentially methylated (p < 0.05) between women with PTB and women with term births. The ability to identify stress-related biological markers that are associated with PTB among Black women would provide a critical step toward decreasing the PTB disparity among these women. Future studies should include larger sample sizes and gene expression analyses of the stress-related biological pathways to PTB.

A Mixed-Methods Study of Experiences During Pregnancy Among Black Women During the COVID-19 Pandemic.

Pregnant women experienced disruptions in their prenatal care during the coronavirus disease-2019 (COVID-19) pandemic. While there is emerging research about the impact of COVID-19 on experiences of pregnancy, the majority of studies that have reported on prenatal care and birth during COVID-19 have not incorporated the first-person accounts of Black women. The purpose of this mixed-methods study was to explore the perspectives of Black women on prenatal care, labor, and birth during the pandemic. A total of 33 participants completed questionnaires. Fourteen of these 33 women and an additional 2 participated in qualitative interviews. Descriptive statistics and a mixed-methods analysis were employed. Participants expressed disappointment about disruptions in their experiences of pregnancy including the way their prenatal care was experienced, cancellation of planned "rites of passage," and visitor policy restrictions during and after the birth. Forty-five percent of participants reported being worried about getting COVID-19 and (61%) about their infant getting COVID-19. Many participants experienced a sense of loss that may permeate through other aspects of their lives. Providing extra support and points of contact can help lessen feelings of isolation during the pandemic and can also offer more explanation for rapidly changing policies and procedures.
