Abstract
BACKGROUND Experiencing symptoms of psychological distress during pregnancy is common and has been linked to dysregulated immune functioning. In this context, immunoregulatory function is especially relevant because of its crucial role in establishment and maintenance of healthy pregnancy. However, little research has examined associations between women's prenatal psychological distress and immunoregulatory biomarkers. We investigated how symptoms of depression, anxiety, and stress relate to circulating levels of regulatory T-cells (Tregs). MATERIALS AND METHODS Pregnant Latina women were assessed at around 12 weeks of pregnancy (N = 82). These assessments included blood draws and self-report questionnaires assessing symptoms of depression, state anxiety, pregnancy-related anxiety, and perceived stress. Flow cytometry on PBMCs was used to quantify circulating Tregs, defined as CD3+CD4+CD25hiCD127loFoxP3+, and subpopulations positive for one of the following intra- or extracellular markers, CD45RA, CTLA-4, Helios, PD-1, TIM-3, and TIGIT. We collected 82 samples at 12 weeks. Multivariable linear regressions tested for associations between symptoms of psychological distress and Treg concentrations, adjusted for gestational age. RESULTS State anxiety symptoms at 12 weeks were negatively associated with parent Treg cell levels (b = -4.02, p = 0.023) and subpopulations Helios+ (b = -3.29, p = 0.019) and TIM3+ (b = -3.17, p = 0.008). Perceived stress was negatively associated with the PD-1+ subpopulation at 12 weeks (b = -4.02, p = 0.023). Depression was not related to Tregs or the subpopulations. CONCLUSION Our observation that symptoms of anxiety and stress are related to tolerogenic immunology suggests a possible biomechanism explaining correlations of maternal mood disorders with adverse outcomes for mothers and offspring.

Neighborhood racial composition and experiences of racial discrimination: Associations with cytokines during pregnancy among African American women. Brain Behav Immun Health 2024; 35:100715. [PMID: 38193096 PMCID: PMC10771980 DOI: 10.1016/j.bbih.2023.100715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 12/08/2023] [Accepted: 12/08/2023] [Indexed: 01/10/2024] Open
Abstract
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 (β = 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.

Abstract
BACKGROUND Independently, active maternal and environmental tobacco smoke exposure and maternal stress have been linked to an increased risk of preterm birth and low birth weight. An understudied relationship is the potential for interactive effects between these risk factors. METHODS Data was obtained from the All Our Families cohort, a study of 3,388 pregnant women < 25 weeks gestation recruited from those receiving prenatal care in Calgary, Canada between May 2008 and December 2010. We investigated the joint effects of active maternal smoking, total smoke exposure (active maternal smoking plus environmental tobacco smoke) and prenatal stress (Perceived Stress Scale, Spielberger State-Trait Anxiety Inventory), measured at two time points (< 25 weeks and 34-36 weeks gestation), on preterm birth and low birth weight. RESULTS A marginally significant association was observed with the interaction active maternal smoking and Spielberger State-Trait Anxiety Inventory scores in relation to low birth weight, after imputation (aOR = 1.02, 95%CI: 1.00-1.03, p = 0.06). No significant joint effects of maternal stress and either active maternal smoking or total smoke exposure with preterm birth were observed. Active maternal smoking, total smoke exposure, Perceived Stress Scores, and Spielberger State-Trait Anxiety Inventory scores were independently associated with preterm birth and/or low birth weight. CONCLUSIONS Findings indicate the role of independent effects of smoking and stress in terms of preterm birth and low birthweight. However, the etiology of preterm birth and low birth weight is complex and multifactorial. Further investigations of potential interactive effects may be useful in helping to identify women experiencing vulnerability and inform the development of targeted interventions.

Abstract
In response to disproportionately high rates of infant mortality and preterm birth among women of color and women in poverty in Fresno County, California, community and academic partners coordinated a community-based participatory research (CBPR) project with local residents. Social isolation and stress, inaccessible prenatal care, and dissatisfaction with care experiences were identified as leading predictors of poor birth outcomes. The PRECEDE-PROCEED framework was used to lead the CBPR effort that resulted in the development of a model of group prenatal care, named Glow! Group Prenatal Care Program (Glow! Program). Group prenatal care (GPNC), which focuses on pregnancy health assessments, education, and peer support, has the potential to address the health and social priorities of women during pregnancy. As a result of the employed CBPR process and the extensive participation from stakeholders, this modified GPNC model responds to the unique needs of the at-risk community members, the agencies aiming to improve maternal-child health experiences and outcomes, and the prenatal care providers offering it to their patients. The methods from this study can be applied in the design and implementation of community-based health care interventions. Returning to community partners throughout the design, implementation, and evaluation phases underscored that health care interventions cannot be designed in silos, and require flexibility to respond to factors that promote improved maternal and infant outcomes, which affect the end goal for the intervention.

Abstract
BACKGROUND In low-income countries, where socioeconomic adversities and perinatal distress are common, adverse birth outcomes are significant public health problems. In these settings, perinatal distress, i.e., high symptoms of anxiety, depression, and/or stress during pregnancy, may be linked with adverse birth outcomes. However, few prospective studies have investigated the impact of perinatal distress on adverse birth outcomes such as preterm birth (gestational age <37 weeks), low birth weight (<2.5 kg), and small for gestational age birth (birth weight below the 10th percentile for gestational age and sex). OBJECTIVES Our main objective was to assess the influence of perinatal distress on adverse birth outcomes. Secondly, to investigate if perinatal distress is an independent risk factor or a mediator in the pathway between socioeconomic adversity and adverse birth outcomes. METHODS In a prospective cohort study following 991 women from before 20 weeks of gestation until delivery in northern Ethiopia, we collected self-reported data on distress at a mean of 14.8 (standard deviation [SD] = 1.9) and 33.9 (SD = 1.1) weeks of gestation. Distress was measured using the Edinburgh Postnatal Depression Scale, the anxiety subscale of the Hospital Anxiety and Depression Scale, and the Perceived Stress Scale. To determine birth outcomes, gestational age was estimated from the last menstrual period, fundal palpation, and/or ultrasound, while birth weight was obtained from delivery records and measured within three days after birth for those delivered at home. Logistic regression and mediation analysis were employed to evaluate the impact of perinatal distress on adverse birth outcomes. RESULTS Perinatal anxiety (OR [95% CI] 1.08 [1.02, 1.13]), depression (1.07 [1.03, 1.11]), stress (1.14 [1.07, 1.22]), and total distress (1.15 [1.07, 1.23]) were all associated with low birth weight, and small for gestational age birth but none did with preterm birth. Mediation analysis demonstrated that perinatal distress was a mediator in the pathway between socioeconomic adversity and adverse birth outcomes. CONCLUSION Our study revealed that perinatal distress was linked with adverse birth outcomes and acted as a mediator between socioeconomic adversity and these outcomes. Our findings highlight the importance of screening women for distress and providing appropriate interventions, focusing on women experiencing socioeconomic adversity. Integrating mental health services into primary maternal care in low-income countries could be an effective approach to achieve this.

Abstract
In theoretical research on disaster vulnerability, access to resources is critical for optimal outcomes. Studying the impact of a hurricane on maternal stress can expand theories of disaster vulnerability. This is a cross-sectional mixed-methods prospective study of maternal stress during Hurricane Florence in the United States. Results from chi-squares compared the proportion of respondents who reported having support for a financial emergency were significant, specifically that higher income respondents indicated the ability to rely on someone in case of an emergency. A regression analysis indicated that social support was significant and negatively related to stress as a dependent variable, while evacuation status and pregnancy status were not significant predictors of stress. Five themes emerged from the overall qualitative data: concerns about infant feeding, evacuation logistics, general stress, family roles, and 'other' issues.

Abstract
Intimate partner violence (IPV) and posttraumatic stress disorder increase the risk of poor pregnancy outcomes, but associations among IPV exposure, mental health, and pregnancy complications remain underexplored. This study assessed the interaction between three types of IPV exposure (i.e., physical, sexual, psychological) and posttraumatic stress symptoms (PTSS) on prenatal complications (e.g., preeclampsia, gestational diabetes) among pregnant women exposed to IPV. Participants included 137 IPV-exposed pregnant women (Mage = 27.29, SD = 6.00; 66.9% African American/Black). Three regression models were run to test the main effect of each type of IPV and PTSS on pregnancy complications, and the moderating effect of PTSS on the association between IPV and pregnancy complications, controlling for socioeconomic status, gestational age, and childhood trauma. Main effects were observed for sexual coercion, β = .32, p = .010, R2 part = .050, and PTSS, β = 0.19, p = .039, R2 part = .026, with more frequent sexual IPV and higher levels of PTSS associated with more pregnancy complications. Moderating effects were also evident, with the IPV x PTSS interaction significant for all three IPV domains: psychological aggression, f2 = .046; sexual coercion, f2 = .079; and physical assault, f2 = .048. PTSS strengthened the positive association between psychological and sexual IPV and pregnancy complications. Physical IPV and pregnancy complications were inversely related for participants with low-level PTSS. Results provide novel information on how IPV types and PTSS function together during pregnancy. Findings highlight the need for evidence-based prenatal interventions that successfully address both IPV exposure and PTSS severity.

Abstract
BACKGROUND Stress can lead to adverse physiological and psychological outcomes. Therefore, understanding stress during pregnancy provides insight into racial disparities in maternal health, particularly Black maternal health. OBJECTIVES This study aimed to describe (1) daily exposure to self-reported stress levels during pregnancy, and (2) sources of stress among participants that identified as Black or White using data collected via ecological momentary assessment. METHODS We leveraged survey data from the Postpartum Mothers Mobile Study, a prospective longitudinal study using ecological momentary assessment data collection methods to describe patterns of stress during pregnancy. This article is descriptive and documents patterns of self-reported stress levels and sources of stress. Frequencies and percentages of stress responses were computed to describe these patterns. RESULTS The sample (n = 296) was 27% Black (n = 78) and 63% White (n = 184). Results were based on at least one measurement of that stress level during pregnancy. A similar number of Black and White participants reported no stress during pregnancy. White (85%-95%) and Black (60%-70%) participants reported low to moderate levels of stress. Black participants (38%) and White participants (35%) reported experiencing high stress. Black and White participants reported similar sources of stress: stress from a partner, too many things to do, a baby or other children, and financial concerns. White participants reported work as a top stressor, and Black participants reported financial issues as a top source of stress. CONCLUSION This study provides insight into daily exposure to stress that has implications for maternal health. We described patterns of self-reported stress and sources of stress among Black and White participants. The daily exposures to stress reported by this sample exist within a context of root causes of structural inequities in education, health care, income, wealth, and housing that must be addressed to achieve maternal health equity.

Abstract
OBJECTIVE High pregnancy anxiety is a consistent predictor of earlier labor and delivery. Placental corticotropin-releasing hormone (pCRH) predicts earlier delivery consistently and it has been identified as a biological mediator of the association between pregnancy anxiety and gestational length. However, studies have not examined whether changes in pregnancy anxiety are associated with earlier birth as mediated by changes in pCRH during pregnancy. Accordingly, this study tests whether linear changes in pregnancy anxiety are associated with length of gestation indirectly through nonlinear increases in pCRH over pregnancy. METHODS A sample of pregnant women (n=233) completed prenatal assessments in early pregnancy, second trimester, and third trimester that included a 4-item assessment of pregnancy anxiety and collection of blood samples assayed for pCRH using radioimmunoassay. Length of gestation was abstracted from medical records after birth. RESULTS Increases in pregnancy anxiety from early pregnancy to third trimester predicted shorted length of gestation, as did nonlinear increases in pCRH over pregnancy. However, there was no evidence of an indirect effect of changes in pregnancy anxiety on length of gestation via changes in pCRH. CONCLUSIONS These results indicate that linear changes in pregnancy anxiety and nonlinear changes in pCRH during pregnancy are independent risk factors for shortened gestational length. This study adds to a small but growing body of work on biopsychological processes in pregnancy and length of gestation. Modeling changes in psychological and biological processes during pregnancy could provide more insight into understanding risk for adverse pregnancy outcomes.

Abstract
INTRODUCTION Up to 40% of patients report depression or anxiety symptoms in pregnancy; feelings of increased stress are nearly universal. Antepartum stress is linked to adverse outcomes including preterm birth, low birthweight, postpartum depression, and maternal self harm. Unfortunately, limited treatment options exist, and patients are often hesitant to initiate medications prenatally. Thus, the development of efficacious nonpharmacologic interventions is crucial. This pilot study investigated the feasibility and impact of an application (app)-based mindfulness practice, begun in the first trimester, on maternal stress and pregnancy outcomes. METHODS The study enrolled patients prior to 15 weeks' gestation and followed them prospectively through birth. Patients were provided with a free subscription to Expectful, a commercially available prenatal mindfulness app, and asked to complete daily meditations. Patients completed the Perceived Stress Scale (PSS) self-assessment at 15 weeks and 28 weeks. PSS scores and pregnancy outcomes were compared with a historical control group of pregnant people who did not use the app. RESULTS Of 68 patients approached, 59 consented to enrollment. Of these, 21 used the app, with an average use of 170 minutes (range, 1.3-1315 min). The average PSS score was significantly lower in the app group at 28 weeks. Additionally, the change in PSS score for app users was greater compared with that of the historical control between enrollment and 28 weeks (-6.3 vs -0.95, P = .0008). Pregnancy outcomes were similar for app users and the historical control. DISCUSSION Our recruitment rate suggests pregnant patients are eager for a nonmedication intervention to decrease stress. However, adherence after enrollment was limited. For a subset of motivated patients, an app-based mindfulness practice significantly reduced perceived stress between the second and third trimesters compared with non-app users. Prenatal mindfulness apps represent an important low-intervention, low-cost, highly accessible tool for managing perinatal mood and stress.

Abstract
BACKGROUND Stress-induced pregnancy complications are thought to represent a significant cause of maternal morbidity and mortality; little is known regarding types of stress most predictive of adverse outcomes. METHODS We used Utah PRAMs 2012-2014 data to evaluate links between preconception life stressors and prevalence of hypertensive disorders of pregnancy (HDP) and pre-term labor (PTB) (births <37 weeks gestational age, and very PTB <33 weeks). We categorized 12 specific stressful events into 4 groups: partner, traumatic, financial, and emotional. Adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were estimated controlling for important sociodemographic, lifestyle, and pregnancy history factors. RESULTS 4,378 mothers completed the survey. 26.6%, 12.2%, 32.2%, and 28.4% reported partner, traumatic, financial, and emotional-related stress. Reporting any of the 4-types of life stress was linked with increased prevalence of HDP (aPR: 1.46 [95% CI: 0.96, 2.22]) after adjusting for age, race/ethnicity, BMI, education, prior diagnosis of high blood pressure, and prior history of preterm labor. The strongest association was observed for financial stress (aPR: 1.50 [95% CI: 1.03, 2.18]). Financial stress was also associated with increased prevalence of very PTB (aPR: 1.61 [95% CI: 1.03, 2.51]) after adjustment. CONCLUSION Women reporting financial stress, including job loss, pay reduction, or difficulty paying bills, had increased prevalence of HDP and very PTB.

The FACAM study: protocol for a randomized controlled study of an early interdisciplinary intervention to support women in vulnerable positions through pregnancy and the first 5 years of motherhood. Trials 2022; 23:73. [PMID: 35073975 PMCID: PMC8785506 DOI: 10.1186/s13063-022-06022-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Accepted: 01/12/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Inequality in health can have profound short- and long-term effects on a child's life. Infants develop in a responsive environment, and the relationship between mother and infant begins to develop during pregnancy. The mother's ability to bond with the fetus and newborn child may be challenged by mental health issues which can cause impaired functioning and poorer health outcomes. Families with complex problems need interdisciplinary interventions starting in early pregnancy to be prepared for motherhood and to ensure healthy child development. This study aims to examine the effects of an early and coordinated intervention (the Family Clinic and Municipality (FACAM) intervention) offered to vulnerable pregnant women during pregnancy and the child's first year of life on the mother-child relationship, maternal social functioning, mental health, reflective functioning, well-being, parental stress, and the development and well-being of the child. METHODS The study is a prospective randomized controlled trial where we will randomize 320 pregnant women enrolled to receive antenatal care at the family clinic at Odense University Hospital, to either FACAM intervention or usual care. The FACAM intervention consists of extra support by a health nurse or family therapist during pregnancy and until the child starts school. The intervention is most intensive in the first 12 months and also includes attachment-based support provided either individually or in groups. The participants are assessed at baseline, and when the infant is 3 and 12 months old. The primary outcome is maternal sensitivity measured by the Coding Interactive Behavior (CIB) instrument. Secondary outcomes include prenatal parental reflective functioning, mental well-being, depressive symptoms, breastfeeding duration, maternal satisfaction, child development, parent competence, parental stress, and activities with the child. DISCUSSION The trial is expected to contribute knowledge about the effect of early coordinated support in antenatal and postnatal care for vulnerable pregnant women and their families. TRIAL REGISTRATION ClinicalTrials.gov NCT03659721 . Registered on September 6, 2018.

Abstract
OBJECTIVES The study investigated the role of social capital, self-efficacy, and depression as determinants of stress during pregnancy. MATERIALS AND METHODS In a cross-sectional study, 200 low-risk pregnant women with at least 5 years of education and ages 18 or more were enrolled in public obstetric clinics of Babol University of Medical Sciences. The participants completed four questionnaires including Social Capital, Revised Prenatal Distress Questionnaire (NuPDQ), Perceived Stress, and General Self-efficacy. RESULTS Women at late phase of pregnancy had lower mean scores of total social capital (61.5 ± 17.1 vs. 47.1 ± 18.1) and self-efficacy (60.1 ± 9.7 vs. 55.1 ± 15.2) compared to those at early pregnancy. Social capital was the negative independent variable associated with pregnancy-specific stress in the adjusted model (β = -0.418, P = 0.020). Both social capital (β = -0.563, P ≤ 0.001) and self-efficacy (β = -0.330, P ≤ 0.001) were negative independent variables associated with general stress. CONCLUSIONS Our findings suggest that health professionals should note the benefits of social capital in stress management and encourage women in establishing stronger relations and neighborhood environments during pregnancy.

Abstract
(1) Background: High stress levels during pregnancy can affect the organogenesis and the foetus’ central nervous system maturation. The objective of this study was to determine whether a relationship between maternal stress during pregnancy and alterations in child neurodevelopment exists; (2) Methods: A bibliographical review was carried out following PRISMA Methodology and using Scopus, Web of Science and Cinahl databases. The research questions were made using PEO methodology (Participants, Exposition, Outcomes). Moreover, article quality was measured using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies; (3) Results: 22 articles that fit the inclusion criteria were selected. Different elements altered because of maternal stress during pregnancy could side with alterations in different areas of the neurodevelopment, such as cognitive development, motor development, behaviour, temperament, memory and learning abilities; (4) Conclusions: Although maternal stress can have an influence on children’s neurodevelopment, it is still unknown which are the specific elements related to this stress that can modify it negatively. Furthermore, future studies should evaluate whether a sex-specific association exists.

Abstract
Purpose This study aimed to identify the components of preterm birth (PTB) through women's personal narratives and to visualize clinical symptom expressions (CSEs). Methods The participants were 11 women who gave birth before 37 weeks of gestational age. Personal narratives were collected by interactive unstructured storytelling via individual interviews, from August 8 to December 4, 2019 after receiving approval of the Institutional Review Board. The textual data were converted to PDF and analyzed using the MAXQDA program (VERBI Software). Results The participants' mean age was 34.6 (±2.98) years, and five participants had a spontaneous vaginal birth. The following nine components of PTB were identified: obstetric condition, emotional condition, physical condition, medical condition, hospital environment, life-related stress, pregnancy-related stress, spousal support, and informational support. The top three codes were preterm labor, personal characteristics, and premature rupture of membrane, and the codes found for more than half of the participants were short cervix, fear of PTB, concern about fetal well-being, sleep difficulty, insufficient spousal and informational support, and physical difficulties. The top six CSEs were stress, hydramnios, false labor, concern about fetal wellbeing, true labor pain, and uterine contraction. "Stress" was ranked first in terms of frequency and "uterine contraction" had individual attributes. Conclusion The text network analysis of narratives from women who gave birth preterm yielded nine PTB components and six CSEs. These nine components should be included for developing a reliable and valid scale for PTB risk and stress. The CSEs can be applied for assessing preterm labor, as well as considered as strategies for students in women's health nursing practicum.

Abstract
BACKGROUND Food insecurity (FI) occurs when people lack secure access to sufficient amounts of safe and nutritious food. FI has been associated with negative effects on human health, including during the prenatal and neonatal periods. The objective of this study is to evaluate the consequences of FI for pregnant women's and newborns' health. METHODS A literature search was performed with three independent researchers based on the PRISMA guidelines; the search covered the period of November 2008 to July 2019 and was conducted in the following databases: the US National Library of Medicine at the National Institutes of Health (PubMed), Latin American and Caribbean Health Sciences (LILACS), Cochrane Library, Web of Science, Embase, Scopus and OpenGrey. The terms and descriptors were defined by consulting the Medical Subject Headings (MeSH) and Health Sciences Descriptors (DeCS) platforms and mainly included "food security", "food insecurity", "pregnancy" and "newborn". The studies were selected through a title and abstract review and then a reading of the full text. The quality of the studies and the risk of bias were analysed based on the criteria defined in the "Joanna Briggs Institute Reviewers' Manual" and by Guyatt and colleagues for interventional studies. The population, study design, FI measurement instruments, FI proportions, outcomes, confounders and results were extracted from the 37 studies that were selected according to the eligibility and quality criteria. RESULTS FI proportions ranged from 5.2 to 87%. Most studies were conducted with African populations (42.2%) and applied globally used scales to assess FI (56.7%); 27% of the studies adapted scales. There were wide variations in the instruments used to estimate FI. The main outcomes related to FI included stress, anxiety and depression during pregnancy, followed by dietary quality and dietary diversity. Associations of FI with birth defects, neonatal mortality and the early introduction of animal milk to the infant's diet were also observed. CONCLUSIONS It is necessary to pay attention to the diversity of FI measurement instruments before FI results are compared. FI can be a risk factor for depression and stress during pregnancy, as well as for neonatal mortality, newborn health problems and breastfeeding interruption. TRIAL REGISTRATION This systematic review was registered on PROSPERO (CRD42018109478).

Abstract
PURPOSE The purpose of the study was to identify to identify the nursing needs and stress levels among spouses of women hospitalized with preterm labor, and to determine factors influencing spousal stress. METHODS Data were collected from 95 spouses of hospitalized pregnant women due to preterm labor at a hospital in Gyeonggi province from June to December of 2016. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression. RESULTS The mean score of spouses' nursing needs was 3.06±0.42 and stress was 1.85±0.44 out of 4.00. The highest score of nursing needs was 3.37±0.51 in assurance and the highest score for stress was 2.26±0.72 for patient's illness and prognosis. There was a significant positive correlation between stress in spouse and nursing needs (p=.004). Stress was explained by nursing needs (β=.28) and hospitalization days (β=.21). CONCLUSIONS: The results of this study suggest that appropriate nursing interventions are required to address the nursing needs at the beginning of hospitalization and to reduce the stress among spouses of hospitalized pregnant women diagnosed with preterm labor.

Abstract
PURPOSE Exposure to prenatal stress has been reported to affect the risk of adverse neurodevelopmental outcomes in the offspring; however, there is currently no clear consensus. The aim of this systematic review and meta-analysis was to examine the existing literature on the association between prenatal stress and autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) in the offspring. METHODS Based on a registered protocol, we searched several electronic databases for articles in accordance with a detailed search strategy. We performed this study following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). RESULTS Prenatal stress was significantly associated with an increased risk of both ASD (pooled OR 1.64 [95% CI 1.15-2.34]; I2 = 90%; 15 articles) and ADHD (pooled OR 1.72 [95% CI 1.27-2.34]; I2 = 85%; 12 articles). CONCLUSIONS This study suggests that prenatal stress may be associated with ASD and ADHD; however, several limitations in the reviewed literature should be noted including significant heterogeneity and there is a need for carefully controlled future studies in this area.

Abstract
Preterm birth is an important issue of public reproductive health worldwide. The effects of the toxic metals on the likelihood of spontaneous preterm birth (SPB) are still under discussion. Our study aimed to investigate the association between maternal exposure to the five typical toxic metals or metalloid (i.e. arsenic (As), cadmium (Cd), chromium (Cr), mercury (Hg), and lead (Pb)) and the SPB likelihood. The mothers delivering fetus with SPB (cases) and those with term healthy birth (controls) were chosen from a prospective birth cohort of 3201 women carried out in Shanxi Province, China. A total of 147 SPB cases and 381 controls were included in our nested case-control study. We collected maternal general information by questionnaire and collected their blood sample during recruitment. The serum concentrations of the five toxic metals were measured by inductively coupled-plasma mass spectrometry. We found that the demographic information between the cases and controls were well balanced. The participants in our study had relatively higher serum As concentration. For the other toxic metals (i.e. Cd, Cr, Hg, and Pb), their serum concentrations were overall in the middle range of those from general population. There were no significant associations of the serum concentrations of the five concerned toxic metals with the SPB likelihood. Our study results overall did not support that maternal exposure to As or Cd significantly contribute to the SPB risk in the current exposure level, as well as the other three toxic metals. We further proposed their upper concentration limits in maternal serum from the perspective of SPB likelihood during the early pregnant period, i.e. 18.2 ng/mL of As, 1.05 ng/mL of Cd, 0.96 ng/mL of Cr, 1.07 ng/mL of Hg, and 1.54 ng/mL of Pb.

Abstract
Background: The effect of maternal mental health during pregnancy on Cesarean section through implications of pre- and postnatal birth have narrowly been investigated. The aim of the present study was to investigate the effect of maternal mental health during pregnancy on the type of delivery in the suburbs of Bandar Abbas. Methods: This study used data of 200 mothers registered in a prospective cohort study on pregnant women in the suburbs of Bandar Abbas, South of Iran, during 2016-18. The presence of depression, anxiety, or stress in expecting mothers were measured by DASS-21 questionnaire and the outcome defined as having Cesarean section (Cesarean section) was measured at postpartum. The relative risk (95% CI) was calculated using Cox regression models. All analyses were performed using STATA statistical package, with a significance level of 5%. Results: Information of 196 mothers were collected (98% response rate); the mean age of the participants was 27.28 (±5.62) years. The prevalence of depression, anxiety, and stress was 13.8% (27), 40.4% (40), and 7.6% (15), respectively. Nearly 40% of mothers went through Cesarean section. Compared to mothers with good mental health, the risk of Cesarean section was 96% higher in depressed mothers (RR=2, 95% CI: 1.43-2.74) (p=0.001), 81% higher in anxious mothers (RR=1.81, 95% CI: 1.29-2.53) (p=0.003), and 75% higher in stressed mothers (RR=1.75, 95% CI: 0.86-3.56) (p=0.121). Conclusion: The findings of this study showed that poor mental health, especially anxiety and depression, during pregnancy could increase the risk of Cesarean section. Accordingly, screening protocols for mental health status and prenatal counseling sessions are suggested for pregnant mothers to increase their informed decision on types of delivery.

Abstract
BACKGROUND An emerging body of literature suggests there is a relationship between a pregnant woman's psychological wellbeing and the development of maternal-fetal attachment (MFA) and early postpartum bonding. The nature of this relationship is not well understood because of the limited theoretical framework surrounding the construct of MFA and variations in study methods and data collection points. In this systematic review, we synthesize the published literature to determine the nature of the relationship from the antenatal to early postnatal period and to provide recommendations for future research and clinical practice. METHOD Using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach, four electronic databases were searched for peer-reviewed empirical studies, published in English. Articles were considered for inclusion if data was collected on at least one domain of maternal wellbeing/mental health and MFA during pregnancy or MFA during pregnancy and the mother-infant relationship during the early postpartum period (up to 12 weeks). No date parameters were applied to the search strategy. The review was registered with PROPSERO (registration number: CRD42018096174). RESULTS 25 studies examining maternal mental health and MFA/postpartum bonding were selected for inclusion in this review. Key findings identified from the review were: a need to validate existing mental health measures or develop new measures specific for use in antenatal populations; inconsistencies in data collection points throughout pregnancy and postpartum; a lack of consensus about the construct of MFA and the way it is assessed; and a continued focus on postpartum outcomes. CONCLUSION Scientific gaps remain in our understanding of the relationship between maternal mental health and both MFA and postpartum bonding which limit our theoretical understanding of the MFA construct. Recommendations for future research are to employ prospective longitudinal designs that span the full pregnancy and postpartum period, and for consistency in the terminology and methodology used when considering MFA. A re-focus of research attention on the theory behind MFA will allow a richer and more holistic account of the emerging relationship between mother and baby.

Abstract
Background: CenteringPregnancy group prenatal care (GPNC) has been shown to reduce rates of preterm birth (PTB). We evaluated the impact of GPNC on spontaneous PTB (sPTB) as a first step in exploring the possible mechanism by which GPNC may decrease rates of PTB. We also evaluated whether attending more than five GPNC sessions affected PTB risk and examined all differences by race/ethnicity. Materials and Methods: We conducted a retrospective cohort study among women delivering at a single institution between April 2009 and March 2014. Birth outcome data from vital statistics records were appended to patient records, and detailed chart abstraction was used to determine spontaneous versus indicated PTB. The association between GPNC and attending more than five GPNC sessions and birth outcomes (i.e., PTB, sPTB, low birth weight [LBW], and neonatal intensive care unit [NICU] admissions) was analyzed using generalized estimating equation log binomial regression models. We examined effect modification of the associations by race/ethnicity. Results: The analysis included 1,292 women in GPNC and 8,703 in traditional individual prenatal care (IPNC). After controlling for potential confounders, the risk of PTB (risk ratio [RR] 0.38; 95% confidence interval [CI] 0.31-0.47), sPTB (RR 0.49; 95% CI 0.38-0.63), LBW (RR 0.46; 95% CI 0.37-0.56), and NICU admissions (RR 0.46; 95% CI 0.37-0.57) was lower in GPNC compared to IPNC women. Results differed by maternal race/ethnicity, with the strongest associations among non-Hispanic white mothers and the weakest associations among Hispanic mothers, especially for sPTB. Similarly, the risk of PTB, LBW, and NICU admissions was lower among GPNC women who attended more than five sessions. Conclusion: Participation in GPNC demonstrated a decreased risk for sPTB, as well as other adverse birth outcomes. In addition, participation in more than five GPNC sessions demonstrated a decreased risk for adverse birth outcomes. Prospective longitudinal studies are needed to further explore mechanisms associated with these findings.

Abstract
Stress in pregnancy is an exceedingly common issue that impacts the mother's mental health and the health of her baby. Yet, women with a supportive network of friends and family may experience lower stress and improved mental health. Therefore, the aims of this secondary analysis were to (a) examine relationships between stress experiences (i.e. perceived stress, pregnancy-specific stress) and indicators of mental health (i.e. absence of depressive symptoms and resourcefulness), (b) determine the effects of social support on stress experiences and indicators of mental health, and (c) determine if social support mediates the relationship between stress experiences and indicators of mental health. A convenience sample of 82 women in their second and third trimester of pregnancy participated in the parent study. Findings indicate that stress experiences were moderately correlated with indicators of mental health and social support predicted stress experiences and indicators of mental health. All social support mediation models were not significant with the exception of social support mediating the relationship between pregnancy-specific stress and resourcefulness. This was the first study to investigate the mediating role of social support on the relationship between pregnancy-specific stress and resourcefulness. Pregnant women may benefit from social support interventions to meaningfully reduce their stress and promote mental health. Such interventions may be physical activity, group prenatal care, or even peripartum home visits.

Abstract
Pregnancy-specific stress (PSS) arises from the numerous changes that women experience during pregnancy and from their concerns about childbirth and the health of their offspring. Prolonged or elevated maternal stress heightens risk for poor fetal, infant, and child outcomes. The Prenatal Distress Questionnaire (PDQ) and its expanded successor, the revised Prenatal Distress Questionnaire (NuPDQ), were developed to assess PSS, but their psychometric properties and findings are not well-documented. We reviewed research using the PDQ (n = 45) or NuPDQ (n = 37). Results establish that PSS as measured by these instruments is common in pregnancy; PSS is associated with sociodemographic and obstetric characteristics, perceptions of pregnancy, health behaviors, maternal health, and birth outcomes. The NuPDQ is an especially appropriate tool to assess PSS, with demonstrated reliability and convergent, concurrent, and predictive validity. The ability to assess PSS in a reliable and valid manner is critical to advance research and improve maternal and child health.

Abstract
BACKGROUND: Breastfeeding plays an important role in both maternal and infant health and well-being. While researchers have examined the relationship between postpartum psychological distress and breastfeeding behaviors, few have investigated links between prenatal distress, postpartum distress, and breastfeeding behaviors over time. RESEARCH AIM: We aimed to determine if prenatal breastfeeding beliefs and psychological distress during and after pregnancy were associated with initiation and early cessation rates of breastfeeding. METHODS: In our secondary data analysis, a nonexperimental longitudinal one-group design was used. We assessed pregnant women ( N = 70) during four perinatal visits (early, mid, and late pregnancy and 7-10 weeks postpartum). Participants completed self-report surveys about psychological distress and depressive symptoms at each visit, breastfeeding beliefs during the third visit, and breastfeeding behaviors at the postpartum visit. RESULTS: Participants who breastfed for ⩾8 weeks had more positive beliefs about breastfeeding prior to delivery than participants with early cessation, who in turn had more positive beliefs than those who never initiated. Participants with early cessation reported heightened levels of pregnancy-specific distress in early pregnancy compared to those who continued breastfeeding or never initiated. Participants who continued breastfeeding for ⩾8 weeks reported less general anxiety and depressive symptoms in postpartum than those who discontinued or never initiated. CONCLUSIONS: Prenatal beliefs about breastfeeding, pregnancy-specific distress in early pregnancy, and general anxiety and depressive symptoms in postpartum are associated with breastfeeding initiation and continuation. Of clinical relevance, addressing prenatal and postpartum distress in the implementation of breastfeeding practice interventions could improve breastfeeding rates.

Abstract
PURPOSE To identify risk factors for premature birth among premature obstetric labor women. METHODS Participants were 129 hospitalized women who were diagnosed with potential premature obstetric labor with 20 weeks to 37 weeks of gestation. Data were analyzed using descriptive statistics, χ2 test, t-test, and binary logistic regression. RESULTS Of 129 women, 78(60.5%) gave premature birth and 51 (39.5%) gave full-term birth. Risk factors for premature birth were education level (≤bachelor's degree), abnormal bowel condition (constipation or diarrhea), time firstly diagnosed with a premature obstetric labor (below 28 weeks of pregnancy), and multiple pregnancy. There were also increased risks of premature birth for participants with high level of anxiety and high level of prenatal stress. In social support, there was an increased risk of premature birth for participants with low level of social support. CONCLUSION Prenatal nursing programs should consider not only psychosocial factors such as anxiety, prenatal stress, and social support, but also some general and obstetric factors such as education level, abnormal bowel condition, time firstly diagnosed with a premature obstetric labor, and multiple pregnancy to increase maternal and child health.

Abstract
Preterm birth continues to be a problem affecting low-, middle-, and high-income countries, with rates increasing in some areas despite ongoing efforts to reduce the incidence. This emphasizes the need for more effective interventions, particularly if we aim to achieve the broad health targets of the Sustainable Development Goals (SDGs) by 2030. The current focus on medically-oriented interventions such as reducing nonmedically-indicated induction of labor, cesarean birth, and multiple embryo transfers associated with assisted reproductive technologies, as well as the application of cervical cerclage and use of progesterone therapy, though important, are likely only partial solutions to the complex phenomenon of preterm birth. Preterm birth has multiple etiologies. The biologic mechanisms involved in preterm labor and how it may be triggered are not well understood. There is growing evidence to suggest some of these triggers may also be related to stress and environmental conditions. In this review, we focus on evidence concerning psychosocial (mind) and environmental factors (environment) as well as briefly review the evidence related to maternal and fetal factors (body) associated with the risk of preterm birth, with reference to some of the SDGs. We also assess emerging evidence regarding the interaction of the body, mind, and environment in relation to preterm birth, currently a gap in our knowledge, and how these interactions could impact clinical practice. Findings suggest that multidisciplinary expertise and approaches will be needed to develop effective interventions to address the complex etiologies of preterm birth, as opposed to single-risk-factor mitigation. Clinicians and researchers will play key roles in identifying many of these risk factors and shaping interventions that address this complex issue. Addressing the interlinkages between body, mind, and environment through the integration of research and clinical practice is critical to reducing the risk of preterm birth and contributing to the achievement of the SDGs.

Abstract
OBJECTIVE The aim of this systematic review was to assess the effect of interventions to reduce stress in pregnant women with a history of miscarriage. DESIGN A systematic review of randomised controlled trials (RCTs). DATA SOURCE A total of 13 medical, psychological and social electronic databases were searched from January 1995 to April 2016 including PUBMED, CENTRAL, Web of Science and EMBASE. ELIGIBILITY CRITERIA This review focused on women in their subsequent pregnancy following miscarriage. All published RCTs which assessed the effect of non-medical interventions such as counselling or support interventions on psychological and mental health outcomes such as stress, anxiety or depression when compared with a control group were included. Stress, anxiety or depression had to be measured at least preintervention and postintervention. RESULTS This systematic review found no RCT which met our initial inclusion criteria. Of the 4140 titles screened, 17 RCTs were identified. All of them were excluded. One RCT, which implemented a caring-based intervention, included pregnant women in their subsequent pregnancy; however, miscarriage was analysed as a composite variable among other pregnancy losses such as stillbirth and neonatal death. Levels of perceived stress were measured by four RCTs. Different types of non-medical interventions, time of follow-up and small sample sizes were found. CONCLUSION Cohort studies and RCTs in non-pregnant women suggest that support and psychological interventions may improve pregnant women's psychological well-being after miscarriage. This improvement may reduce adverse pregnancy-related outcomes in subsequent pregnancies. However, this review found no RCTs which met our criteria. There is a need for targeted RCTs that can provide reliable and conclusive results to determine effective interventions for this vulnerable group.

Abstract
PURPOSE The aim of this study was to determine the influence of various factors on preterm labor symptoms (PLS) and preterm birth (PB). METHODS This prospective cohort study included 193 women in the second stage of pregnancy. Multiple characteristics including body mass index (BMI), smoking, and pregnancy complications were collected through a self-report questionnaire. Pregnancy stress and PLS were each measured with a related scale. Cervical length and birth outcome were evaluated from medical charts. Multiple regression was used to predict PLS and logistic regression was used to predict PB. RESULTS Multiple regression showed smoking experience, pregnancy complications and pregnancy specific stress were predictors of PLS and accounted for 19.2% of the total variation. Logistic regression showed predictors of PB to be twins (OR=13.68, CI=3.72~50.33, p<.001), shorter cervix (<25mm) (OR=5.63, CI=1.29~24.54, p<.05), BMI >25 (kg/m²) (OR=3.50, CI=1.35~9.04, p<.01) and a previous PB (OR=4.15, CI=1.07~16.03, p<.05). CONCLUSION The results of this study show that the multiple factors affect stage II pregnant women can result in PLS or PB. And preterm labor may predict PB. These findings highlight differences in predicting variables for pretrm labor and for PB. Future research is needed to develop a screening tool to predict the risk of preterm birth in pregnant women.

Abstract
Over the last two decades, numerous studies have suggested that dedicated time for parents to be with their children in the earliest months of life offers significant benefits to child health. The United States (US) is the only wealthy nation without a formalized policy guaranteeing workers paid time off when they become new parents. As individual US states consider enacting parental leave policies, there is a significant opportunity to decrease health inequities and build a healthier American population. This document is intended as a critical review of the present evidence for the association between paid parental leave and population health.

Abstract
BACKGROUND Economic interventions are increasingly recognised as a mechanism to address perinatal health outcomes among disadvantaged groups. In the US, the earned income tax credit (EITC) is the largest poverty alleviation programme. Little is known about its effects on perinatal health among recipients and their children. We exploit quasi-random variation in the size of EITC payments to examine the effects of income on perinatal health. METHODS The study sample includes women surveyed in the 1979 National Longitudinal Survey of Youth (n = 2985) and their children born during 1986-2000 (n = 4683). Outcome variables include utilisation of prenatal and postnatal care, use of alcohol and tobacco during pregnancy, term birth, birthweight, and breast-feeding status. We first examine the health effects of both household income and EITC payment size using multivariable linear regressions. We then employ instrumental variables analysis to estimate the causal effect of income on perinatal health, using EITC payment size as an instrument for household income. RESULTS We find that EITC payment size is associated with better levels of several indicators of perinatal health. Instrumental variables analysis, however, does not reveal a causal association between household income and these health measures. CONCLUSIONS Our findings suggest that associations between income and perinatal health may be confounded by unobserved characteristics, but that EITC income improves perinatal health. Future studies should continue to explore the impacts of economic interventions on perinatal health outcomes, and investigate how different forms of income transfers may have different impacts.
