- Abstract
To evaluate the association between prenatal stress and gestational weight gain (GWG). This was an analysis of women recruited between 2013–2015 from four sites in the US. We tested associations between responses at 32–35 weeks to the Life Experiences Survey (LES), a 37-item measure of events and perceived stress, and GWG categories. Bivariable comparisons and logistic regression were used to estimate the association between the total LES score and the odds of achieving adequate GWG. Among the 725 women, those with adequate GWG had lower median LES scores (5) compared to women with inadequate (7) and excessive (7) GWG, p?=?0.02. After adjusting for age, initial BMI, income, education, marital status and gestational diabetes, lower LES scores (multiples of the median) were associated with adequate GWG (aOR 0.81, 95% CI 0.67–0.98). Lower reported stress, as measured by the LES, was associated with a greater chance of women achieving adequate GWG. This relationship highlights the potential for interventions directed toward psychosocial support to have salutary effects upon GWG.

Fetal growth nomograms were developed to screen for fetal growth restriction and guide clinical care to improve perinatal outcomes; however, existing literature remains inconclusive regarding which nomogram is the gold standard. This study aimed to compare the ability of 4 commonly used nomograms (Hadlock, International Fetal and Newborn Growth Consortium for the 21st Century, Eunice Kennedy Shriver National Institute of Child Health and Human Development–unified standard, and World Health Organization fetal growth charts) and 1 institution-specific reference to predict small for gestational age and poor neonatal outcomes. This was a retrospective cohort study of all nonanomalous singleton pregnancies undergoing ultrasound at ≥20 weeks of gestation between 2013 and 2020 and delivering at a single academic center. Using random selection methods, the study sample was restricted to 1 pregnancy per patient and 1 ultrasound per pregnancy completed at ≥22 weeks of gestation. Fetal biometry data were used to calculate estimated fetal weight and percentiles according to the aforementioned 5 nomograms. Maternal and neonatal data were extracted from electronic medical records. Logistic regression was used to estimate the association between estimated fetal weight of <10th and <3rd percentiles compared with estimated fetal weight of 10th to 90th percentile as the reference group for small for gestational age and the neonatal composite outcomes (perinatal mortality, hypoxic-ischemic encephalopathy or seizures, respiratory morbidity, intraventricular hemorrhage, necrotizing enterocolitis, hyperbilirubinemia or hypoglycemia requiring neonatal intensive care unit admission, and retinopathy of prematurity). Receiver operating characteristic curve contrast estimation (primary analysis) and test characteristics were calculated for all nomograms and the prediction of small for gestational age and the neonatal composite outcomes. We restricted the sample to ultrasounds performed within 28 days of delivery; moreover, similar analyses were completed to assess the prediction of small for gestational age and neonatal composite outcomes. Among 10,045 participants, the proportion of fetuses classified as <10th percentile varied across nomograms from 4.9% to 9.7%. Fetuses with an estimated fetal weight of <10th percentile had an increased risk of small for gestational age (odds ratio, 9.9 [95% confidence interval, 8.5–11.5] to 12.8 [95% confidence interval, 10.9–15.0]). In addition, the estimated fetal weight of <10th and <3rd percentile was associated with increased risk of the neonatal composite outcome (odds ratio, 2.4 [95% confidence interval, 2.0–2.8] to 3.5 [95% confidence interval, 2.9–4.3] and 5.7 [95% confidence interval, 4.5–7.2] to 8.8 [95% confidence interval, 6.6–11.8], respectively). The prediction of small for gestational age with an estimated fetal weight of <10th percentile had a positive likelihood ratio of 6.3 to 8.5 and an area under the curve of 0.62 to 0.67. Similarly, the prediction of the neonatal composite outcome with an estimated fetal weight of <10th percentile had a positive likelihood ratio of 2.1 to 3.1 and an area under the curve of 0.55 to 0.57. When analyses were restricted to ultrasound within 4 weeks of delivery, among fetuses with an estimated fetal weight of <10th percentile, the risk of small for gestational age increased across all nomograms (odds ratio, 16.7 [95% confidence interval, 12.6–22.3] to 25.1 [95% confidence interval, 17.0–37.0]), and prediction improved (positive likelihood ratio, 8.3–15.0; area under the curve, 0.69–0.75). Similarly, the risk of neonatal composite outcome increased (odds ratio, 3.2 [95% confidence interval, 2.4–4.2] to 5.2 [95% confidence interval, 3.8–7.2]), and prediction marginally improved (positive likelihood ratio, 2.4–4.1; area under the curve, 0.60–0.62). Importantly, the risk of both being small for gestational age and having the neonatal composite outcome further increased (odds ratio, 21.4 [95% confidence interval, 13.6–33.6] to 28.7 (95% confidence interval, 18.6–44.3]), and the prediction of concurrent small for gestational age and neonatal composite outcome greatly improved (positive likelihood ratio, 6.0–10.0; area under the curve, 0.80–0.83). In this large cohort, Hadlock, recent fetal growth nomograms, and a local population-derived fetal growth reference performed comparably in the prediction of small for gestational age and neonatal composite outcomes.

To assess the validity of Spanish versions of the Survey of Well-being of Young Children (SWYC) Milestones and the Ages & Stages Questionnaire, Third Edition (ASQ-3), and to document the rates of developmental delays in an urban cohort of children with Hispanic parents. Spanish-speaking families with a child 9 to 60 months of age (N = 991) were initially screened using Spanish translations of the SWYC Milestones and the ASQ-3. A stratified random sample of 494 of these children subsequently received standardized clinical assessment to confirm the presence of developmental delays. Reverse weighting corrected for the selection bias inherent in the stratification scheme. Fifty-five percent of toddlers (9 to 41 months of age) and 34.8% of preschoolers (42 to 60 months of age) scored in the moderately to severely delayed range, most frequently in language. Sensitivity and specificity for toddlers with severe delays associated with the SWYC were 0.69 and 0.64, respectively, and 0.55 and 0.75 for the ASQ-3. Sensitivity and specificity for preschoolers with severe delays associated with the SWYC were 0.87 and 0.58, respectively, and 0.71 and 0.86 for the ASQ-3. Although psychometric properties of the Spanish translated versions are not as strong as the English versions, the findings suggest that both the SWYC Milestones and ASQ-3 represent promising tools for identifying Hispanic children with developmental delays. The rate of delays were consistent with other studies showing a high percentage of Hispanic children with developmental delays, most frequently in language skills. [ABSTRACT FROM AUTHOR]

In 2009, the National Academy of Sciences (NAS) called for more interdisciplinary and communityengaged approaches to teaching and learning in the agricultural and life sciences to better respond to the food system challenges of the 21st century. As a result, institutions from across the nation have responded with a number of experiential learning and service-learning frameworks and practices aimed to enhance the academic experience for both student and community stakeholders. Sustainable agriculture education, with its explicit focus on experiential learning, interdisciplinarity, and values-based programming, has emerged as a promising approach to strengthen the fabric of agriculture and life sciences education. The purpose of this paper is to illustrate the complex role of service learning as a central approach to undergraduate teaching and learning where interdisciplinary teaching, experiential learning, and community engagement are core goals. Specifically, we conducted a single embedded case study of a sustainable agriculture education program at a land grant university to explore how this triad was organized and possible service learning outcomes. Our case study was informed by semi-structured interviews of faculty and community partner stakeholders, participant observations of faculty and students, and secondary data analysis of course syllabi and other programmatic artifacts. Despite different understandings and practices of service learning by faculty within this, we found a common core of best practices. We conclude with criteria and best practices to guide teaching and learning from this triad perspective. [ABSTRACT FROM AUTHOR]

The inclusion of service-learning in higher education is an opportunity to enhance experiential curricula to increase student success post-graduation in the current dynamic and challenging job market. However, designing effective assessments to measure learning that takes place outside the classroom may be a difficult aspect for educators interested in including community- based learning opportunities in their curricula. A 2014 Community Nutrition course incorporating a service-learning assignment is used as an example of Assessment for Learning to achieve predetermined learning objectives. The purpose of this paper is to illustrate how educators can implement structured, multi-faceted assessment within service-learning using intentionally designed assignments that include multiple points of feedback to students, providing opportunities for reflection and learning. Examples of assessment tools that can be applied to a variety of class structures and environments are also provided. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose Patient-centered health care recognizes that adolescents and parents are stakeholders in adolescent health. We investigate adolescent and parent interest in receiving information about health topics and parent-teen communication from clinicians. Methods Ninety-one parent-adolescent dyads in one practice completed individual interviews. Items assessed levels of interest in receiving health and health communication information from the adolescent's doctor about 18 topics, including routine, mental health, sexual health, substance use, and injury prevention issues. Analyses tested differences between parents and adolescents, within-dyad correlations, and associations with adolescent gender and age. Results Most parents were female (84%). Adolescents were evenly divided by gender; 36 were aged 12–13 years, 35 were aged 14–15 years, and 20 were aged 16–17 years. Adolescent race reflected the practice population (60% black; 35% white). The vast majority of parents and adolescents reported moderate or high levels of interest in receiving information about all 18 health issues and information to increase parent-teen communication about these topics. Parents' interest in receiving information varied by adolescent age when the expected salience of topics varied by age (e.g., acne, driving safety), whereas adolescents reported similar interest regardless of age. Adolescent gender influenced parent and adolescent interest. Level of interest in receiving information from doctors within adolescent-parent pairs was not significantly correlated for one-half of topics. Conclusions Parents and adolescents want health care professionals to help them learn and talk about a wide range of adolescent health topics. Feasible primary care interventions that effectively improve parent-teen health communication, and specific adolescent health outcomes are needed. [ABSTRACT FROM AUTHOR]

The National Academy of Sciences called for a dynamic approach to teaching and learning in colleges of agriculture. In response, faculty at colleges and universities are implementing innovative frameworks for undergraduate education in the agricultural sciences. This study explored the collaborative and interdisciplinary teaching and learning practices of faculty in sustainable agriculture education curricula at a land grant university as an illustration of this innovation. Drawing upon a sociocultural learning framework, this study specifically emphasizes faculty work as a social practice and the inherently relational learning that occurs with other faculty, their students and community partners. Using an in-depth, qualitative research approach, a single embedded case study design was implemented to illustrate the teaching and learning experiences of an interdisciplinary group of faculty collaborating within an undergraduate minor that fosters community engagement through service-learning and sustainable agriculture curricula. The collaborative teaching structure that is explored is comprised of an instructor of record, collaborating faculty, community-partner and graduate teaching assistant. Faculty teaching in this program of study experience learning in the areas of disciplinary knowledge and pedagogical practice and navigate organizational challenges and barriers to collaborative work.

BREASTFEEDING ,POOR women ,RACE - Abstract
The promotion of breastfeeding as the ?ideal? infant feeding method has become an important public health campaign to improve infant health in the United States. Researchers have consistently documented lower breastfeeding initiation and duration rates among African Americans, teenagers, and low-income mothers. This paper examines the factors associated with both breastfeeding initiation and duration among low-income women from diverse racial, ethnic and immigrant backgrounds in Philadelphia. In addition to examining the relationship between socio-demographic characteristics and infant feeding practice, as many previous studies have done, we also include measures of household conditions and privacy, maternal health behaviors during pregnancy, WIC participation, birth/pregnancy characteristics, and health care and hospital practices regarding breastfeeding promotion. We will investigate the relative importance of these various factors on racial and ethnic differences in breastfeeding initiation and duration among non-Hispanic white, non-Hispanic African Americans, immigrant blacks, Puerto Ricans and other Hispanic women, using data from the Community Roles in Birth Outcomes Study (CRIB). The analyses will provide insight into who decides to initiate breastfeeding among an inner-city population, who continues and for how long among those mothers who initiate, and how these patterns vary by race, ethnicity, and nativity status. We use breastfeeding practice to explore how individual behaviors and actions, especially among a "high-risk" population, need to be contextualized within the lives and circumstances within which they are shaped and enacted.

- Abstract
The placenta is the principal regulator of the in uteroenvironment, and disruptions to this environment can result in adverse offspring health outcomes. To better characterize the impact of in uteroperturbations, we assessed the influence of known environmental pollutants on the expression of microRNA (miRNA) in placental samples collected from the National Children's Study (NCS) Vanguard birth cohort. This study analyzed the expression of 654 miRNAs in 110 term placentas. Environmental pollutants measured in these placentas included dichlorodiphenyldichloroethylene (DDE), bisphenol A (BPA), polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), arsenic (As), mercury (Hg), lead (Pb), and cadmium (Cd). A moderated t-test was used to identify a panel of differentially expressed miRNAs, which were further analyzed using generalized linear models. We observed 112 miRNAs consistently expressed in >70% of the samples. Consistent with the literature, miRNAs located within the imprinted placenta-specific C19MC cluster, specifically mir-517a, mir-517c, mir-522, and mir-23a, are among the top expressed miRNA in our study. We observed a positive association between PBDE 209 and miR-188–5p and an inverse association between PBDE 99 and let-7c. Both PCBs and Cd were positively associated with miR-1537 expression level. In addition, multiple let-7 family members were downregulated with increasing levels of Hg and Pb. We did not observe DDE or BPA levels to be associated with placental miRNA expression. This is the first birth cohort study linking environmental pollutants and placental expression of miRNAs. Our results suggest that placental miRNA profiles may signal in uteroexposures to environmental chemicals.

Preterm birth is a syndrome with many causes and phenotypes. We propose a classification that is based on clinical phenotypes that are defined by ≥1 characteristics of the mother, the fetus, the placenta, the signs of parturition, and the pathway to delivery. Risk factors and mode of delivery are not included. There are 5 components in a preterm birth phenotype: (1) maternal conditions that are present before presentation for delivery, (2) fetal conditions that are present before presentation for delivery, (3) placental pathologic conditions, (4) signs of the initiation of parturition, and (5) the pathway to delivery. This system does not force any preterm birth into a predefined phenotype and allows all relevant conditions to become part of the phenotype. Needed data can be collected from the medical records to classify every preterm birth. The classification system will improve understanding of the cause and improve surveillance across populations.

A comprehensive classification system for preterm birth requires expanded gestational boundaries that recognize the early origins of preterm parturition and emphasize fetal maturity over fetal age. Exclusion of stillbirths, pregnancy terminations, and multifetal gestations prevents comprehensive consideration of the potential causes and presentations of preterm birth. Any step in parturition (cervical softening and ripening, decidual-membrane activation, and/or myometrial contractions) may initiate preterm parturition, and should be recorded for every preterm birth, as should the condition of the mother, fetus, newborn, and placenta, before a phenotype is assigned.

In 2009, the Global Alliance to Prevent Prematurity and Stillbirth Conference charged the authors to propose a new comprehensive, consistent, and uniform classification system for preterm birth. This first article reviews issues related to measurement of gestational age, clinical vs etiologic phenotypes, inclusion vs exclusion of multifetal and stillborn infants, and separation vs combination of pathways to preterm birth. The second article proposes answers to the questions raised here, and the third demonstrates how the proposed system might work in practice. [ABSTRACT FROM AUTHOR]

Culhane, Jennifer F. and Goldenberg, Robert L.
- Abstract
In the United States, there is a pronounced and persistent race/ethnic disparity in the rate of preterm birth. Even after decades of basic science research and public health initiatives this disparity remains relatively unchanged. Factors that underpin this disparity are elusive and likely, at least in part, derived from complex mechanisms originating from social inequities. In this article several promising areas of research are explored. Specifically, social context or neighborhood-level exposures, maternal nativity, infection/inflammation, and preconception health differentials are discussed in the context of increasing risk of preterm birth among race/ethnic minorities.

Denney, Jeff M. and Culhane, Jennifer F.
- Abstract
Summary: Bacterial vaginosis (BV) infections are common in women of reproductive age and are easily diagnosed and treatable. Aside from being an annoyance when symptoms of discharge, odor, and pruritus occur in the gravid female, BV infections increase risk of late miscarriage, preterm labor, preterm premature rupture of membranes, and, consequently, preterm delivery. Antepartum and puerperal issues such as chorioamnionitis and endometritis are increased in the context of maternal BV. Moreover, the morbidities and mortality of preterm delivery are consequently increased as a result of BV during pregnancy. Although the pathology associated with BV appears to result from inflammation, more investigation is needed in terms of designing guidelines for appropriate screening and treatment for the prevention of adverse outcomes.

The article discusses a study which evaluated short-term outcomes associated with discordant twin pairs admitted to the neonatal intensive care unit (NICU). The study involved 384 discordant twin pairs whose mean gestational age was 32.6 weeks. It was concluded that larger twins had more acute respiratory issues but achieved certain milestones more rapidly with fewer complications.

Objective: This study was undertaken to assess if levels of interleukin-1β (IL-1β), IL-8, sialidase, prolidase and immunoglobulin A against Gardenerella vaginalis hemolysin (anti-Gvh IgA) in vaginal secretions differ between BV+ women with (M +) and without (M-) Mobiluncus spp. Study design: Vaginal secretions were obtained from 265 women at their first prenatal care visit and assessed for all study parameters. Gram stain evaluation using Nugent criteria was performed and coinfection with sexually transmitted infections determined. Differences between BV +/M+ and BV+/M-women were evaluated using the χ
2 statistic or Mann-Whitney test. Results: Of the 265 BV+ women, 43% (n = 113) were M+ of which 97% (n = 110) had Nugent scores of 9 or 10. BV+/M+ women had elevated levels of sialidase (median value: 4.11 nmol vs 1.91 nmol of converted substrate; P = .003) but no difference in prolidase, anti-Gvh IgA, IL-1β, IL-8, levels were found between the two groups. BV+/M-women had significantly higher rates of coinfection with Trichomonas vaginalis. Conclusion: BV+/M + women have higher vaginal concentrations of sialidase and lower rates of T vaginalis compared with BV+/M-women. Further research is needed to assess the association of this, and other, microbiologic profiles to risk of adverse pregnancy outcome. [ABSTRACT FROM AUTHOR]- Published

Objective: The purpose of this study was to assess the contribution of depressive symptoms and poor contraceptive use early in the first postpartum year to the risk of unintended repeat pregnancy at the end of that year among adults with low educational status (<12th grade or equivalence). Study design: This was a prospective observational cohort study of 643 sexually active, low-income, inner-city adult women (age ≥ 19) who enrolled prenatally (14.7 ± 6.9 weeks gestational age) and were followed twice after delivery (3.3 ± 1.3 months and 11.0 ± 1.3 months). Associations were assessed by multivariate logistic regression. Results: Low educational status (odds ratio, 2.32; 95% CI, 1.25-4.33) and less effective contraceptive use (odds ratio, 2.31; 95% CI, 1.05-4.51) were associated with unintended pregnancy. Neither depressive symptoms nor contraceptive use reduced the risk of pregnancy that was associated with low educational status. Conclusion: Low educational status was associated with more than twice the risk of unintended pregnancy 1 year after delivery. We found no evidence that depression or poor contraceptive use mediate this relationship. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To describe the range of risk reduction behaviors among women who continue to smoke after learning of their pregnancy, including reduced tobacco use, eventual cessation, and sustained abstinence as well as the patient-reported smoking cessation-promoting behaviors of prenatal care providers. Methods: This research is part of a larger prospective, community-based study conducted to assess the association between maternal stress and birth outcomes and infant health and development. Over a 2-year period, from February 2000 to November 2001, women receiving prenatal care at a consortium of public health centers in Philadelphia, Pennsylvania, were consecutively recruited (n = 1,451) completing interviews at their initial prenatal visit and again 3 to 4 months following their delivery. Smoking rates during pregnancy were determined from responses given during the first postpartum interview, at 3 to 4 months postpartum. Results: Of the 1,451 women interviewed at 3 to 4 months postpartum, 24.9 percent indicated smoking during their pregnancy. Of these antenatal smokers, 89.0 percent reported reducing their cigarette consumption during pregnancy. However, only 25.4 percent attained abstinence during their pregnancy. Among women who achieved abstinence during their pregnancy, 21.7 percent were still not smoking at the time of the postpartum interview. Antenatal smokers reported that prenatal care providers asked about their smoking (90.6%) and advised about quitting (76.5%). However, only 27.9 percent were given referrals to smoking cessation programs. Conclusion: While cessation was achieved by only a quarter of antenatal smokers, almost 90 percent reduced their cigarette consumption. Prenatal care providers identified and provided cessation advice to the majority of women who were smoking but they did not follow through with material assistance in the form of referrals to smoking cessation programs.

- Abstract
Objectives.-To describe where women receiving prenatal care (PNC) at community-based health centers (CBHCs) go for infant primary care, and to assess reasons for and factors associated with leaving CBHCs and using other practices for infant care. Methods.-A prospective survey of women receiving PNC at CBHCs from February 2000 to February 2002 was conducted. In-person, prepartum, and postpartum surveys included questions about sociodemographic and health characteristics, and health services use. Results,-Among 1107 primarily low-income, African American mothers, 60% of women left CBHCs and used other practices for their infants due to dissatisfaction, inconvenience, referral to and perceived expertise at other sites, and insurance changes. Leaving CBHCs was associated with being white, Latina, US born, educated beyond high school, single, owning a car, using non-CBHC practices for prepregnancy care, and having child health insurance. Among those who left, 48% used hospital-based clinics (HBCs) and 52% used private practices (PPs). Mothers using HBCs, when compared to those using PPs, were more likely to be African American (AOR = 6.83: 95% CI: 3.82, 12.22) or Latina (AOR = 5.60: 95% CI: 2.79, 11.24), dissatisfied with their PNC (AOR = 2.02, 95% CI: 1.05, 3.89) and to leave CBHCs because of insurance changes (AOR = 2.27: 95% CI: 1.18, 4.39) and perceived pediatric expertise at other sites (AOR = 4.81: 95% CI: 2.53, 9.11). Conclusions-The majority of women in our study left CBHCs and used other sites for pediatric care. Higher education, having child health insurance, and car ownership were associated with leaving CBHCs. Among women who left, race/ethnicity and perceived pediatric expertise were major factors associated with using HBCs rather than PPs. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to determine if clinical findings and sociodemographic variables among bacterial vaginosis (BV)-positive pregnant women are associated with different microbiologic profiles. Study design: Pregnant women were assessed for BV by Nugent criteria. BV+ women were separated into 6 mutually exclusive microbiologic groups. In unadjusted analyses, we compared (1) sociodemographic and behavioral characteristics, and (2) 3 clinical characteristics among BV+ women with and without Mobiluncus (M+ vs M-). Unadjusted data were analyzed using the chi-square test. Multiple logistic regression was used to assess the likelihood of having clinical signs of BV in women with and without Mobiluncus spp while controlling for confounders. Results: A total of 1756 BV+ pregnant women were followed. The M+ group (n = 702) was significantly more likely than the M- group (n = 1054) to be non-Hispanic black (80.9% vs 66.2%; P < .0001), older than 21 years (61.7% vs 48.7%; P < .0001), and to have had more than 3 lifetime sexual partners (66.4% vs 54.9%; P < .0001). The M+ group was also more likely to have clue cells on wet mount (63.9% vs 47.2%; P < .0001) and a positive amine odor after addition of KOH (57.2% vs 45.0%; P = .001). There was no difference in other demographic variables or physician diagnosis of abnormal vaginal discharge. In the adjusted analyses for each clinical outcome, all findings were consistent with the unadjusted analyses. Conclusion: BV+ pregnant women with Mobiluncus spp are more likely to have clue cells present on wet mount, a positive amine odor after KOH preparation, and to be older, non-Hispanic black, and have had more lifetime sexual partners compared to BV+ women without any Mobiluncus species.

Racial and social class differences in rates of preterm birth and other adverse outcomes are among the most widely recognized and least well-understood phenomena in the study of reproductive health. Individual-level characteristics have failed to account for such gradients. Recently, researchers have begun to argue that health in general and reproductive outcomes specifically are rooted in social inequalities. One area of such inequality may be residential segregation and the associated race/ethnic differences in exposure to adverse neighborhood conditions. We review the empiric data that examine the association between neighborhood conditions and reproductive health. We also review the major challenges that researchers face when trying to incorporate neighborhood-level variables into studies of health outcomes. Our goal is to stimulate further research that simultaneously considers social, economic, and biologic determinants of reproductive health. [ABSTRACT FROM AUTHOR]

PREGNANCY complications ,BACTERIAL diseases - Abstract
Objective: The purpose of this study was to assess the contribution of chronic social stressors to race/ethnic differences in the rate of bacterial vaginosis among pregnant women in the inner-city area.Study Design: We conducted a cross-sectional clinical prevalence study in a sample of 2304 women at the first prenatal visit (14.8 +/- 0.2 weeks of gestation). Bacterial vaginosis was diagnosed by Nugent's method. Stress was measured at the individual and community levels with the use of interviews and administrative records. Logistic regression was used to assess the effects of stress on the odds of bacterial vaginosis occurrence, after adjustment for demographic and behavioral risk.Results: Black women had significantly higher rates of bacterial vaginosis (64%) compared with white women (35%). Exposure to chronic stressors at the individual level differed by race (eg, 32% of the black women reported threats to personal safety compared with 13% of white women). There were significant racial differences in exposure to stress at the community level (eg, 63% of the black women lived in neighborhoods with aggravated assault rates that were above the citywide mean compared with 25% of the white women). After the adjustment for sociodemographic, behavioral risk, and perceived stress, the odds of the occurrence of bacterial vaginosis that was associated with the community level stressor of "homelessness" was significant (odds ratio, 6.7; 95% CI, 1.6-27.8). Inclusion of both individual and community level stressors reduced the black/white bacterial vaginosis odds ratio by 27%.Conclusion: Stressful exposures are associated positively with bacterial vaginosis in pregnancy in a sample of women of low income in the inner city. The measurement of stressors at multiple levels explained a significant proportion of the racial disparity in the rates of occurrence of bacterial vaginosis. [ABSTRACT FROM AUTHOR]- Published

Background: The American College of Obstetricians and Gynecologists recommends that pregnant patients receive expeditious treatment with first-line antihypertensive agents within 1 hour of confirmed severe hypertension to reduce the risk for maternal stroke. However, it is unknown how often this guideline is followed and what factors influence a patient's likelihood of receiving guideline-concordant care.Objective: We aimed to identify factors associated with receiving guideline-concordant treatment for an obstetrical hypertensive emergency.Study Design: We present a case-control study of all pregnant and postpartum patients who had persistent severe hypertension (≥2 systolic blood pressures ≥160 mm Hg or diastolic blood pressure ≥110 mm Hg, or both within 1 hour of each other) during their delivery hospitalization at a tertiary hospital from October 1, 2013, to August 31, 2020. Data were extracted from the hospital electronic medical records using standard definitions and billing and diagnosis codes. We defined receipt of the recommended treatment as administration of a first-line antihypertensive agent (intravenous labetalol, intravenous hydralazine, or immediate-release oral nifedipine) within 60 minutes of the first or second severe-range blood pressure measurement during their delivery hospitalization. Delayed treatment was defined as the administration of a first-line agent >60 minutes after the second elevated blood pressure measurement. Patients were considered untreated if a first-line agent was never administered. Maternal sociodemographic, clinical and pregnancy factors, and time and day of the week of the hypertensive emergency were compared among patients who received the recommended treatment, those who received delayed treatment, and those who were untreated. Bivariate analyses were performed, and multinomial and multivariable logistic regression models were used to adjust for potential confounders.Results: Of the 39,918 deliveries in the cohort, 1987 (5.0%) were complicated by severe, persistent obstetrical hypertension. Of these patients, 532 (26.8%) received the recommended treatment, 356 (17.9%) received delayed treatment, and 1099 (55.3%) did not receive any first-line antihypertensive therapy. The multinomial regression models that were used to compare these 3 groups indicated that patients who received the recommended treatment were more likely to be Black (adjusted odds ratio, 1.85; 95% confidence interval, 1.36-2.51), Hispanic (adjusted odds ratio, 1.77; 95% confidence interval, 1.28-2.52), or pregnant and at <37 weeks of gestation (adjusted odds ratio, 6.65; 95% confidence interval, 5.08-8.72). Treatment was less likely if the severe obstetrical hypertension emergency occurred overnight (7:00 PM to 6:59 AM) (adjusted odds ratio, 0.79; 95% confidence interval, 0.64-0.97) or during the postpartum period (adjusted odds ratio, 0.66; 95% confidence interval, 0.51-0.86).Conclusion: Approximately half of obstetrical patients with at least 2 documented severely elevated blood pressure measurements did not receive the recommended antihypertensive treatment. Of those who did receive treatment, about 40% had delayed treatment. Black and Hispanic race and preterm gestation were associated with an increased likelihood of receiving the recommended treatment when compared with White race and term pregnancies. Patients whose severe obstetrical hypertension emergency occurred overnight and those who were postpartum were less likely to receive any first-line antihypertensive treatment. Overall, patients without sociodemographic and clinical risk factors for severe obstetrical hypertension or other pregnancy complications were less likely to be treated. However, treatment improved significantly over time with the implementation of targeted quality measures and specific institutional policies based on the American College of Obstetricians and Gynecologists' latest severe obstetrical hypertension management guidelines.

- Abstract
Purpose. To understand how social and structural contexts shape individual risk, vulnerability, and interconception health-related behaviors of African-American women.Approach or Design. A longitudinal ethnographic study was conducted.Setting. The study was conducted in Philadelphia, Pennsylvania.Participants. The sample included 19 African-American women who were participants in the intervention group of a randomized clinical trial of interconceptional care.Method. Data were collected through interaction with participants over a period of 6 to 12 months. Participant observation, structured and unstructured interviews, and Photovoice were used to obtain data; grounded theory was used for analysis. The analysis was guided by intersectional theory.Results. Social disadvantage influenced health and health care–seeking behaviors of African-American women, and the disadvantage centered on the experience of racism. The authors identify seven experiences grounded in the interactions among the forces of racism, class, gender, and history that may influence women's participation in and the effectiveness of preconception and interconception health care.Conclusion. African-American women's health and wellness behaviors are influenced by an experience of racism structurally embedded and made more virulent by its intersection with class, gender, and history. These intersecting forces create what may be a unique exposure that contributes significantly to the proximal determinants of health inequities for African-American women. Health promotion approaches that focus on the individual as the locus of intervention must concomitantly unravel and address the intertwining structural forces that shape individual circumstance in order to improve women's interconceptional health and to reduce disparities.

Background: Hypertension was redefined in 2017 with lower diagnostic thresholds; elevated blood pressure is defined as systolic blood pressure of 120 to 129 mm Hg with diastolic blood pressure of <80 mm Hg and stage 1 hypertension as systolic blood pressure of 130 to 139 mm Hg or diastolic blood pressure of 80 to 89 mm Hg. These guidelines did not include pregnant women. There is limited information on stage 1 hypertension and pregnancy outcomes.Objective: This study aimed to determine whether elevated blood pressure and stage 1 hypertension as newly defined by the 2017 American College of Cardiology and the American Heart Association guidelines are associated with an increased risk of hypertensive disorders of pregnancy and other adverse maternal and neonatal outcomes.Study Design: In this retrospective cohort study, 18,801 women with singletons from 2013 to 2019 were categorized as normotensive, prehypertensive (elevated blood pressure), stage 1 hypertensive, or chronic hypertensive. Women with ≥2 systolic blood pressures of 120 to 129 mm Hg before 20 weeks' gestation were classified into the elevated blood pressure group. Women with ≥2 systolic blood pressures of 130 to 139 mm Hg or ≥2 diastolic blood pressures of 80 to 89 mm Hg before 20 weeks' gestation were assigned to the stage 1 hypertension group. Women were classified as chronic hypertensives if they had any of the following: ≥2 systolic blood pressure of ≥140 mm Hg or ≥2 diastolic blood pressure of ≥90 mm Hg before 20 weeks' gestation, a history of chronic hypertension, or antihypertensive medication use before 20 weeks' gestation. Women with pregestational diabetes, lupus, or <2 blood pressures before 20 weeks' gestation were excluded. The association of stage 1 hypertension with the risk of developing hypertensive disorders of pregnancy was estimated using multivariate logistic regression controlling for maternal sociodemographic characteristics, gestational weight gain by prepregnancy body mass index, parity, and aspirin use. Secondary outcomes included subgroups of hypertensive disorders (gestational hypertension, preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, and low platelet count syndrome), gestational diabetes, placental abruption, intrauterine growth restriction, preterm birth, neonatal intensive care unit admission, stillbirth and neonatal death, and maternal intensive care unit admission. All outcomes were adjusted for potential confounders.Results: Of the 18,801 women, 13,478 (71.7%) were normotensive, 2659 (14.1%) had elevated blood pressure, 1384 (7.4%) were stage 1 hypertensive, and 1280 (6.8%) were chronic hypertensive. A dose-response relationship was observed: the risk of hypertensive disorders of pregnancy increased from 4.2% in normotensive women to 6.7% (adjusted odds ratio, 1.50; 95% confidence interval, 1.26-1.79) in women with elevated blood pressure, to 10.9% (adjusted odds ratio, 2.54; 95% confidence interval, 2.09-3.08) in women with stage 1 hypertension, and 28.4% (adjusted odds ratio, 7.14; 95% confidence interval, 6.06-8.40) in women with chronic hypertension. Compared with normotensive women, women with stage 1 hypertension had an increased risk of neonatal intensive care unit admissions (15.8% vs 13.0%; adjusted odds ratio, 1.21; 95% confidence interval, 1.03-1.42), preterm birth at <37 weeks' gestation (7.2% vs 5.2%; adjusted odds ratio, 1.45; 95% confidence interval, 1.16-1.81), and gestational diabetes (14.8% vs 6.8%; adjusted odds ratio, 2.68; 95% confidence interval, 2.27-3.17).Conclusion: Our study demonstrates that elevated blood pressure and stage 1 hypertension, using the 2017 American College of Cardiology and the American Heart Association guideline definition, are associated with increased maternal and neonatal risk. This group of women warrants further investigation to determine whether pregnancy management can be altered to reduce maternal and neonatal morbidity. [ABSTRACT FROM AUTHOR]- Published

Mendez, Dara D., Hogan, Vijaya K., and Culhane, Jennifer
- Abstract
Objectives. We used Home Mortgage Disclosure Act (HMDA) data to demonstrate a method for constructing a residential redlining index to measure institutional racism at the community level. We examined the application of the index to understand the social context of health inequities by applying the residential redlining index among a cohort of pregnant women in Philadelphia.Methods. We used HMDA data from 1999–2004 to create residential redlining indices for each census tract in Philadelphia County, Pennsylvania. We linked the redlining indices to data from a pregnancy cohort study and the 2000 Census. We spatially mapped the levels of redlining for each census tract for this pregnancy cohort and tested the association between residential redlining and other community-level measures of segregation and individual health.Results. From 1999–2004, loan applicants in Philadelphia County, Pennsylvania, of black race/ethnicity were almost two times as likely to be denied a mortgage loan compared with applicants who were white (e.g., 1999 odds ratio [OR] = 2.00, 95% confidence interval [CI] 1.63, 2.28; and 2004 OR=2.26, 95% CI 1.98, 2.58). The majority (77.5%) of the pregnancy cohort resided in redlined neighborhoods, and there were significant differences in residence in redlined areas by race/ethnicity (p<0.001). Among the pregnancy cohort, redlining was associated with residential segregation as measured by the percentage of black population (r=0.155), dissimilarity (r=0.250), exposure (r=–0.115), and isolation (r=0.174) indices.Conclusions. The evidence of institutional racism may contribute to our understanding of health disparities. Residential redlining and mortgage discrimination against communities may be a major factor influencing neighborhood structure, composition, development, and wealth attainment. This residential redlining index as a measure for institutional racism can be applied in health research to understand the unique social and neighborhood contexts that contribute to health inequities.

- Abstract
Objectives. We determined the prevalence of first lifetime use of cigarettes during pregnancy or in the early postpartum period (incident smoking) and identified sociodemographic and health-related characteristics of incident smokers.Methods. We used statistics based on data from a longitudinal study of a large cohort of pregnant, low-income, urban women (n= 1,676) to describe the timing of first-time use and to compare incident smokers with those who had never smoked and those who had already smoked prior to pregnancy.Results. About one in 10 (10.2%) women who had not previously smoked initiated cigarette smoking during pregnancy or in the early postpartum period. Compared with those who had never smoked, incident smokers were more likely to report high levels of stress and to have elevated levels of depressive symptomatology, which may be rooted in relatively poor social and economic conditions.Conclusion. A significant number of women may be initiating smoking during pregnancy or in the early postpartum period. These women have characteristics that are consistent with the risk factors associated with smoking. Further research is warranted to determine prevalence in other populations, identify the risk factors for incident smoking, and assess the potential for primary prevention efforts designed to help women who had previously avoided cigarette use to remain smoke-free throughout pregnancy and in the postpartum period.
