The buffering effect of social support on hypothalamic-pituitary-adrenal axis function during pregnancy

The social and healthcare professional support drawn upon by women antenatally during the COVID-19 pandemic: A recurrent, cross-sectional, thematic analysis

OBJECTIVE

To explore antenatal experiences of social and healthcare professional support during different phases of social distancing restriction implementation in the UK.

DESIGN

Semi-structured interviews were conducted via telephone or video-conferencing software between 13 July 2020 - 2 September 2020. Interviews were transcribed and a recurrent, cross-sectional, thematic analysis was conducted.

PARTICIPANTS

Twelve antenatal women were interviewed during UK social distancing restrictions (Timepoint 1; T1) and a separate sample of twelve women were interviewed in the initial easing of these restrictions (Timepoint 2; T2).

FINDINGS

T1 themes were: 'Maternity care as non-essential' and 'Pregnancy is cancelled'. T2 themes were: 'Technology is a polarised tool' and 'Clinically vulnerable, or not clinically vulnerable? That is the question'.

KEY CONCLUSIONS

At T1, anxieties were ascribed to the exclusion of partners from routine care, and to perceived insensitivity and aggression from the public. For T2, insufficient Governmental transparency led to disillusionment, confusion, and anger. Covert workplace discrimination also caused distress at T2. Across timepoints: deteriorated mental wellbeing was attributed to depleted opportunities to interact socially and scaled back maternity care.

IMPLICATIONS FOR PRACTICE

Recommendations are made to: protect maternal autonomy; improve quality of mental health and routine care signposting; prioritise parental community support in the re-opening of 'non-essential' services; prioritise the option for face-to-face appointments when safe and legal; and protecting the rights of working mothers.

In the pandemic from the womb. Prenatal exposure, maternal psychological stress and mental health in association with infant negative affect at 6 months of life

For mother-infant health especially, the pandemic has brought multiple stressors inside a susceptible psychobiological system. We study the longitudinal associations between maternal prenatal and postpartum: (a) COVID-19 stressful events exposure, (b) pandemic psychological stress, and (c) mental health and infants' negative affect. A sample of 643 Italian pregnant women completed a web-based survey from April 8th to May 4th, 2020 and a follow-up at 6 months after delivery. Maternal assessment covered prenatal and postpartum measures for: COVID-19 stressful events exposure, pandemic psychological stress, mental health symptoms (i.e., depression, anxiety, posttraumatic stress disorder) and postpartum, social support and report of infants' negative affect. Maternal mental health symptoms during pregnancy, at the peak of pandemic, is longitudinally associated with infant negative affect, with postpartum mental health mediating this association. Also, maternal COVID-19 stressful events exposure in postpartum is associated with negative affect at 6 months mediated by postpartum mental health symptoms. Maternal pandemic psychological stress during pregnancy predicted mental health symptoms in postpartum. The study supports the association between pandemic-related maternal health across pregnancy and postpartum and offspring's development (i.e., negative affect). It also puts the spotlight on mental health risk in women experiencing lockdown during pregnancy, especially when feeling high psychological stress in pregnancy or when directly exposed to COVID-19 stressful events postpartum.

Early-life matters: The role of fetal adrenal steroids in the relationship between cytokines within the placental circulation and cognitive development among infants in the Philippines

Prenatal exposure to inflammation is related to the risk for cognitive impairment in offspring. However, mechanisms underlying the link between inflammatory cytokines at the maternal-fetal interface and human cognitive development are largely unknown. This study addressed this research gap by examining whether i) cytokines within the placenta are associated with different domains of neurocognitive development during infancy, and ii) if DHEA-S in cord blood mediates these associations. We also explored the role of early-life socioeconomic status (SES) in moderating the effect of fetal adrenal steroids on cognitive development in low- and middle-income country contexts. A cohort of 242 mother-infant dyads in Leyte, the Philippines participated in the study and all of them were followed from early pregnancy until 12-months. Concentrations of pro- and anti-inflammatory cytokines in the placenta, and DHEA-S in cord blood collected at delivery were evaluated. The multifactorial aspects of the infant's cognitive functioning were assessed based on the Bayley Scales of Infant Development, third edition (BSID-III). We used Structural Equation Modelling (SEM) with an orthogonal rotation to examine associated paths among latent variables of pro- and anti-inflammatory cytokines in the placenta, fetal neuroendocrine factors, and cognitive development. Pathway analyses showed that both pro- and anti-inflammatory cytokines in the placenta were indirectly related to cognitive (p < 0.05) and language developmental outcomes (p < 0.1) via DHEA-S in cord blood among the low SES group. Yet, we found no statistically significant indirect effect of pro- or anti-inflammatory cytokines on neurocognitive development among the high SES sub-sample. This study extends our understanding of how early-life socioeconomic conditions modify biological pathways underlying the relationship between prenatal factors and postpartum cognitive development.

Social Support Buffers the Effects of Prenatal Depressed Mood: A Mixed-Methods Study

BACKGROUND: Women use various coping strategies to deal with stress and depression. These strategies are shaped by social contexts over the life course and may attenuate and/or exacerbate the physiologic effects of depression. AIMS: The purpose of this study was to determine whether coping strategies (active, disengaged, or social support coping) moderate depression-related diurnal cortisol dysregulation and to explore how social context influences women's use of coping. METHODS: This was a mixed-methods study of pregnant women (N = 65) during mid-pregnancy. Cortisol was measured in saliva collected during the waking hours of the day. Participants completed the Edinburgh Depression Scale and the Brief COPE. A subset of the sample participated in semistructured qualitative interviews (n = 20). RESULTS: Social support coping, but not active or disengaged coping, moderated end-of-day cortisol levels. Among depressed women, higher use of social support was associated with lower and more dynamic (i.e., less flat) diurnal cortisol rhythms. The qualitative findings revealed how complex social dynamics related to financial insecurity, lack of mutuality, and social identity affected women's use of and access to social support. CONCLUSION: These findings support theories of the stress-buffering effects of social support. Future research is needed to examine how social determinants affect access to social support, and how early life social experiences condition women's adaptive formation of social support coping strategies over the life course. Clinically, these findings underscore the value of relationship-centered nursing care for depressed women.

Nature-based interventions to support mental health and well-being of young women in pregnancy: exploratory work for future feasibility RCT

Background

The prevalence of mental health and well-being issues among young women is increasing. Pregnancy is a time when new mental health challenges may arise, or existing conditions can be exacerbated. This project presents preparatory work on how nature-based interventions may help to support the mental health and well-being of young pregnant women (aged 16-24 years) in a future study.

Methods

This project was formed of three main phases conducted from March to August 2022: (1) mapping nature activities available across the East Midlands region and two focus groups with providers of nature activities (n = 6); (2) public participation and involvement work to inform future research. This included four focus groups with young women (n = 11), leading to the formation of a new young women's panel (Research Influencers Group). Networking and stakeholder engagement to support future research.

Results

The mapping survey identified 68 nature-based organisations/projects operating in the region, many of whom expressed interest in being involved in future research. The young women's focus groups confirmed the importance of the topic and generated a wealth of information to support the intervention design. A Research Influencer Group of five young women was established from the focus group participants. The Research Influencer Group chose the nature-based intervention and had input into all aspects of the study design. This group will continue into future projects. Focus groups with providers of nature activities have further advanced the study design. The project team have developed relationships with relevant stakeholders and networks that will inform the future trial.

Conclusion

This preparatory co-design work suggested that a nature-based intervention may be acceptable to young women, and providers of such interventions felt it was feasible to offer these activities to young pregnant women. This preparatory work has led to an outline research plan which has been co-produced with public contributors and stakeholders throughout.

Limitations

This preparatory work is limited by small focus group samples, and the possibility that not all providers were reached through the snowballing approach to the mapping survey.

Future work

Future research is needed to test the nature-based intervention; this would be in the form of a feasibility randomised controlled trial of nature-based interventions to promote the mental health and well-being of young pregnant women.

Experience of mental health in women with Polycystic Ovary Syndrome: a descriptive phenomenological study

Purpose: This study aims to investigate the experiences, emotional coping strategies, and help-seeking needs of women with PCOS from their perspective, considering common psychological issues such as stress, anxiety, and depression that are prevalent among individuals with PCOS. Materials and Methods: The study recruited 14 women with PCOS for semi-structured interviews between October and November 2022, using a descriptive phenomenology method design. The interviews were analyzed using NVivo 12 software. Results: Four themes and eleven subthemes were derived from the semi-structured interviews: (1) Negative Mental Health Status; (2) Four Patterns of Emotion Regulation; (3) The Psychological Double-Edged Sword: Family Social Network; (4) Strong Demands for Psychological Counseling and Lifestyle Guidance. Conclusion: The study suggests that interventions should focus on fostering internalized self-efficacy and emotional expression, promoting constructive familial support, and providing psychological counseling and lifestyle recommendations to alleviate psychological distress experienced by women with PCOS.

Maternal Early Life Adversity and Infant Stress Regulation: Intergenerational Associations and Mediation by Maternal Prenatal Mental Health

Early life adversity is a potent risk factor for poor mental health outcomes across the lifespan, including offspring vulnerability to psychopathology. Developmentally, the prenatal period is a sensitive window in which maternal early life experiences may influence offspring outcomes and demarcates a time when expectant mothers and offspring are more susceptible to stressful and salutary influences. This prenatal plasticity constituted the focus of the current study where we tested the association of maternal early life adversity with infant stress regulation through maternal prenatal internalizing symptoms and moderation by prenatal social support. Mother-infant dyads (n = 162) were followed prospectively and mothers completed assessments of social support and depressive and anxiety symptoms across pregnancy. Infants completed standardized stress paradigms at one month and six months. There were several key findings. First, maternal prenatal depressive symptoms significantly mediated predictions of infant cortisol reactivity to the heel stick at one month from maternal early life adversity: specifically, maternal early life adversity positively predicted depressive symptoms in pregnancy, which in turn predicted dampened infant cortisol reactivity. Second, prenatal social support did not significantly moderate predictions of depressive or anxiety symptoms in pregnancy from maternal early life adversity nor did it alter the associations of maternal depressive or anxiety symptoms with infant stress regulation. These results suggest that maternal prenatal mental health is a key mechanism by which maternal early life adverse experiences affect offspring risk for psychopathology. We discuss potential clinical and health implications of dysregulated infant cortisol reactivity with respect to lifespan development.

Maternal prenatal social contact during the COVID-19 pandemic predicts infant birth weight

BACKGROUND

Social connectedness and mental health have been associated with infant birth weight, and both were compromised by the COVID-19 pandemic.

AIMS

We sought to examine whether changes in maternal prenatal social contact due to the COVID-19 pandemic were associated with infant birth weight and if maternal prenatal mental health mediated this association.

STUDY DESIGN

A longitudinal study of mothers and their infants born during the first wave of the COVID-19 pandemic.

SUBJECTS

The sample consisted of 282 United States-based mother-infant dyads.

OUTCOME MEASURES

Depressive symptoms were measured with the Beck Depression Inventory-II, anxiety was measured with the State Anxiety Inventory, and stress was measured using the Perceived Stress Scale 14. We also asked participants about pandemic-related changes in social contact across various domains. Adjusted birth weight was calculated from birth records or participant-report when birth records were unavailable.

RESULTS

Decreases in social contact during the pandemic were associated with lower adjusted infant birth weight (B = 76.82, SE = 35.82, p = .035). This association was mediated by maternal prenatal depressive symptoms [Effect = 15.06, 95 % CI (0.19, 35.58)] but not by prenatal anxiety [95 % CI (-0.02, 32.38)] or stress [95 % CI (-0.31, 26.19)].

CONCLUSION

These findings highlight concerns for both mothers and infants in the wake of the COVID-19 pandemic, since birth weight can have long-term health implications and the social restructuring occasioned by the pandemic may lead to lasting changes in social behavior.

How prenatal cortisol levels relate to grandmother-mother relationships among a cohort of Latina women

INTRODUCTION

As part of the human reproductive strategy, mothers receive childcare assistance from others. For kin, allomothers are adaptively incentivized to provide assistance due to inclusive fitness benefits. Previous studies across a broad range of populations identify grandmothers as particularly consistent allomothers. Minimal attention has been paid to the possibility that allomothers may begin investing in offspring quality during the prenatal stage of life. Here, we innovate within the area of grandmother allocare research by examining the prenatal stage of life and biopsychosocial mechanisms by which prenatal grandmother effects may be enacted.

METHODS

Data derive from the Mothers' Cultural Experiences study, a cohort of 107 pregnant Latina women in Southern California. At <16 weeks' gestation, we administered questionnaires, collected morning urine samples, and measured cortisol by enzyme-linked immunosorbent assay, correcting for specific gravity. We measured the soon-to-be maternal and paternal grandmothers' relationship quality, social support, frequency of seeing each other, communicating, and geographic proximity to pregnant mothers, that is, their daughters and daughters-in-law. These measures were self-reported by the pregnant mothers. We assessed how grandmother constructs related to the pregnant women's depression, stress, anxiety, and cortisol levels.

RESULTS

We observed benefits conferred by maternal grandmothers for mothers' prenatal mental health and lower cortisol levels. Paternal grandmothers also conferred mental health benefits to pregnant daughters-in-law, but higher cortisol levels.

CONCLUSION

Our results suggest that grandmothers, especially maternal grandmothers, are able to improve their inclusive fitness by caring for pregnant daughters, and allomother support may positively impact prenatal health. This work extends the traditional cooperative breeding model by identifying a prenatal grandmother effect, and, by examining a maternal biomarker.

Perspectives about social support among unmarried pregnant university students in South Africa

BACKGROUND

Pregnant young women in an academic environment are susceptible to stressors associated with unintended pregnancy and academic demands of universities. The challenges they face may be exacerbated by lack of social support, putting them at risk of psychological disorders such as depression. Women who receive social support during pregnancy and postpartum experience less emotional distress and report greater maternal satisfaction. However, very little is known about the perspectives about social support among unmarried pregnant students in tertiary institutions.

METHODS

Participants were purposively selected among unmarried pregnant students and those in the puerperal period at the time of the study. We conducted semi-structured qualitative interviews to explore the perspectives of unmarried pregnant students on the type of support that they need during pregnancy and the puerperium and the period when most support is needed. The data were audio-recorded and transcribed verbatim, then analysed using thematic analysis.

RESULTS

The findings show that social supports (emotional, instrumental, informational, and financial) were highlighted as important resources to cope with stressors during pregnancy and post-birth. Emotional support from male partners was the most important type of support needed as it entailed a sense of being loved and cared for. Social support was identified as important throughout the different phases of pregnancy and post birth, with different support needs expressed at each of these phases.

CONCLUSION

This study identified support needs of unmarried pregnant university students in their transition to motherhood. Given the several challenges that they are faced with, unmarried pregnant students need social support, including male partner support to enhance wellbeing as they try to cope with academic and pregnancy-related stressors.

Associations between psychological distress and hair cortisol during pregnancy and the early postpartum: A meta-analysis

Pregnancy and the early postpartum signify a period of high stress. Perinatal stress can include psychological distress (PD), such as anxiety, depression, and stress, as well as neuroendocrine stress, indexed by activation of the hypothalamic-pituitary-adrenal (HPA) axis and the production of the hormone cortisol. Elevated PD and cortisol levels during the perinatal period can have long-term implications for the mother and child. Methodological advances have enabled the sampling of cortisol from hair, to provide a retrospective marker of HPA axis activity over several months. Despite knowing that maternal PD and HPA activity during the perinatal period independently impact health and development, research to date is unclear as to the association between maternal PD and hair cortisol. The present meta-analysis included 29 studies to assess the strength of the relation between maternal PD and hair cortisol levels during pregnancy and the early postpartum period. Several sample and methodological factors were assessed as moderators of this effect. Analyses were conducted using multilevel meta-analysis. Results of the multilevel meta-analysis indicated that the overall effect size between PD and HCC was small but not significant z = 0.039, 95% CI [- 0.001, 0.079]. Moderator analyses indicated that the strength of the association between PD and hair cortisol was moderated by pregnancy status (i.e., effects were stronger in pregnant compared to postpartum samples), timing of HCC and PD measurements (i.e., effects were larger when PD was measured before HCC) and geographic location (i.e., effects were larger in North American studies). The findings advance our understanding of the link between PD and HPA activity during the perinatal period, a time of critical impact to child development.

Prenatal Stress and the Developing Brain: Postnatal Environments Promoting Resilience

Heightened maternal stress during pregnancy is associated with atypical brain development and an elevated risk for psychopathology in offspring. Supportive environments during early postnatal life may promote brain development and reverse atypical developmental trajectories induced by prenatal stress. We reviewed studies focused on the role of key early environmental factors in moderating associations between prenatal stress exposure and infant brain and neurocognitive outcomes. Specifically, we focused on the associations between parental caregiving quality, environmental enrichment, social support, and socioeconomic status with infant brain and neurocognitive outcomes. We examined the evidence that these factors may moderate the effects of prenatal stress on the developing brain. Complementing findings from translational models, human research suggests that high-quality early postnatal environments are associated with indices of infant neurodevelopment that have also been associated with prenatal stress, such as hippocampal volume and frontolimbic connectivity. Human studies also suggest that maternal sensitivity and higher socioeconomic status may attenuate the effects of prenatal stress on established neurocognitive and neuroendocrine mediators of risk for psychopathology, such as hypothalamic-pituitary-adrenal axis functioning. Biological pathways that may underlie the effects of positive early environments on the infant brain, including the epigenome, oxytocin, and inflammation, are also discussed. Future research in humans should examine resilience-promoting processes in relation to infant brain development using large sample sizes and longitudinal designs. The findings from this review could be incorporated into clinical models of risk and resilience during the perinatal period and used to design more effective early programs that reduce risk for psychopathology.

Associations Between ADHD Symptoms and Maternal and Birth Outcomes: An Exploratory Analysis in a Multi-Country Cohort of Expectant Mothers

OBJECTIVE

ADHD symptoms can adversely impact functioning in a range of domains relevant for maternal well-being and fetal development; however, there has been almost no research examining their impact during pregnancy. We aimed to address this gap.

METHOD

We used data (n = 1,204) from a longitudinal birth cohort study spanning eight countries to address this gap.

RESULTS

ADHD symptoms in the third trimester of pregnancy were associated with lower social support from family (b = -0.16, p = .031), friends (b = -0.16, p = .024), and significant others (b = -0.09, p = .001); higher stress (b = 0.34, p < .001) and depressive symptoms (b = 0.31, p < .001), and increased likelihood of an unwanted pregnancy (b = 0.30, p = .009). Significant associations with tobacco use (b = 0.36, p = .023) and premature birth (b = 0.35, p = .007) did not survive correction for multiple comparisons and there were no significant associations with alcohol use, low birth weight, or unplanned pregnancy.

CONCLUSION

Results suggest that women with ADHD symptoms could benefit from earlier, more regular screening for mental health difficulties and greater mental health support during pregnancy.

Prenatal Maternal Distress During the COVID-19 Pandemic and Associations With Infant Brain Connectivity

BACKGROUND

The COVID-19 pandemic has caused substantially elevated distress in pregnant individuals, which has the potential to affect the developing infant brain. Our main objective was to understand how prenatal distress was related to infant brain structure and function and whether social support moderated the associations.

METHODS

The Pregnancy during the COVID-19 Pandemic (PdP) cohort study collected Patient-Reported Outcomes Measurement Information System Anxiety scale, Edinburgh Postnatal Depression Scale, and Social Support Effectiveness Questionnaire data from a population-based sample of pregnant individuals living in Canada (N = 8602). For a subsample of participants, their infants (n = 75) underwent magnetic resonance imaging at 3 months of age to examine whether prenatal maternal distress was associated with infant brain architecture, including the role of social support as a potential protective factor.

RESULTS

Overall, 33.4% of participants demonstrated clinically elevated depression symptoms and 47.1% of participants demonstrated clinically elevated anxiety symptoms. We identified lower social support as a significant predictor of clinically elevated prenatal maternal distress (t8598 = -22.3, p < .001). Fifty-eight diffusion image datasets (20 female/38 male, 92 ± 14 days old) and 41 functional datasets (13 female/28 male, 92 ± 14 days old) were included in our analysis after removal of poor-quality images and infants without postpartum maternal distress scores. We found significant relationships between prenatal maternal distress and infant amygdala-prefrontal microstructural and functional connectivity measures, and we demonstrate for the first time that social support moderates these relationships.

CONCLUSIONS

Our findings suggest a potentially long-lasting impact of the COVID-19 pandemic on children and show that social support acts as a possible mediator not just for pregnant individuals but also developing infants. These findings provide timely evidence to inform clinical practice and policy surrounding the care of pregnant individuals and highlight the importance of social support.

The Impact of COVID-19 on Maternal Mental Health during Pregnancy: A Comparison between Canada and China within the CONCEPTION Cohort

The effect of the COVID-19 pandemic on maternal mental health has been described in Canada and China but no study has compared the two countries using the same standardized and validated instruments. In this study, we aimed to evaluate and compare the impact of COVID-19 public health policies on maternal mental health between Canada and China, as we hypothesize that geographical factors and different COVID-19 policies are likely to influence maternal mental health. Pregnant persons >18 years old were recruited in Canada and China using a web-based strategy. All participants recruited between 26 June 2020 and 16 February 2021 were analyzed. Self-reported data included sociodemographic variables, COVID-19 experience and maternal mental health assessments (Edinburgh Perinatal Depression Scale (EPDS), Generalized Anxiety Disorders (GAD-7) scale, stress and satisfaction with life). Analyses were stratified by recruitment cohort, namely: Canada 1 (26 June 2020-10 October 2020), Canada 2 and China (11 October 2020-16 February 2021). Overall, 2423 participants were recruited, with 1804 participants within Canada 1, 135 within Canada 2 and 484 in China. The mean EDPS scores were 8.1 (SD, 5.1) in Canada 1, 8.1 (SD, 5.2) in Canada 2 and 7.7 (SD, 4.9) in China (p-value Canada 2/China: p = 0.005). The mean GAD-7 scores were 2.6 (SD, 2.9) in China, 4.3 (SD, 3.8) in Canada 1 (p < 0.001) and 5.8 (SD, 5.2) in Canada 2 (p < 0.001). When adjusting for stress and anxiety, being part of the Chinese cohort significantly increased the chances of having maternal depression by over threefold (adjusted OR 3.20, 95%CI 1.77-5.78). Canadian and Chinese participants reported depressive scores nearly double those of other crises and non-pandemic periods. Lockdowns and reopening periods have an important impact on levels of depression and anxiety among pregnant persons.

Molecular changes in nucleus accumbens due to amelioration of depressive-like behavior by housing with companion

Social support are positively and causally related to mental health. Higher levels of perceived social support and group memberships are shown to be associated with lower depression symptomatology and recovery from depression, but the molecular biological mechanism behind its remains largely unknown. Here, we report that accompanying with companion ameliorated chronic unpredictable mild stress (CUMS) induced depression-like behaviors in mice. Accompanying with companion altered RNA expression profiles of nucleus accumbens (NAc) in CUMS-induced susceptible and resilience mice. 117 differentially expressed genes (DEGs) were found to be associated with depression-like behaviors, 17 DEGs associated with resilient behaviors, 43 DEGs associated with accompanying with companion. Importantly, 234 differentially expressed miRNAs that associated with accompanying with companion were obtained, and the miRNA-mRNA network associated with companion was established in NAc, based on the miRNA and mRNA profiles. Taken together, our findings revealed a potential new approach to improve depression-like behaviors, as well as many potential drug targets for the prevention or treatment of depression.

Coparenting-focused preventive intervention reduces postnatal maternal BMI and buffers impact of cortisol

OBJECTIVE

The postpartum period is a key life stage, contributing to increased maternal obesity risk. Current lifestyle interventions do not consider the role of a woman's partner in reducing stress and supporting lifestyle change. The objective of this study was to assess the effect of an intervention that seeks to enhance coparenting relationship quality on maternal BMI from before conception to 12 months post partum and whether the intervention moderated the association of changes in cortisol and BMI.

METHODS

A randomized controlled trial was used to assess an intervention (eight classes: four during and four following pregnancy) focusing on enhancing couple coparenting relationships during pregnancy and post partum (n = 57) compared with standard care (n = 53).

RESULTS

The main outcome measures were changes in maternal BMI and cortisol. There was a smaller increase in BMI for mothers in intervention compared with control groups (mean [SE], -1.03 [0.42] kg/m2 , p = 0.015). There was an interaction between intervention status and cortisol change predicting BMI change (p = 0.026), such that cortisol change significantly predicted BMI change among mothers in the control (p = 0.049) but not the intervention groups (p = 0.204).

CONCLUSIONS

A coparenting intervention improved maternal postpartum BMI, with this effect potentially related to ameliorating the negative effect of stress, as measured by cortisol, on BMI. The role of enhanced coparenting in improving maternal anthropometry warrants urgent attention.

Levels and Predictors of Anxiety and Depression in Turkish Pregnant Woman During the Covid-19 Pandemic

OBJECTIVE

 In addition to being a medical phenomenon, pandemics affect the individual and society on several levels and lead to disruptions. In the pandemic process, different groups in the population, including pregnant women as a defenseless group, are subjected to psychological threat. The present study aimed to determine the levels of anxiety and depression and related factors in pregnant women during the the coronavirus disease 2019 (Covid-19) pandemic.

METHODS

 The present cross-sectional study was conducted with 269 pregnant women through face-to-face interviews held in Istanbul, Turkey. Regarding the data collection tools, the Cronbach α reliability coefficient was of 0.90 for the Beck Anxiety Inventory, and of 0.85 for the Beck Depression Inventory.

RESULTS

 Among the participating pregnant women, 30.5% had mild, 17.5% had moderate, and 5.9% had severe anxiety symptoms, whereas 35.3% had mild, 16.7% had moderate, and 2.2% had severe depression symptoms. We found that those who were concerned about their health had 5.36 times (p = 0.04) more risk of developing anxiety, and 4.82 times (p = 0.01) more risk of developing depression than those who were not concerned. Those who had a history of psychiatric disease had 3.92 times (p = 0.02) more risk of developing anxiety than those without it.

CONCLUSION

 We determined that about half of the pregnant women included in the study had some degree of anxiety and depression during the COVID-19 pandemic. The risk factors for anxiety and depression among the pregnant women were determined as smoking, concerns about health and getting infected with the coronavirus, history of psychiatric disease, and undergoing regular antenatal care.

The Alberta Pregnancy Outcomes and Nutrition (APrON) longitudinal study: cohort profile and key findings from the first three years

PURPOSE

The objectives of the ongoing Canadian longitudinal cohort called the Alberta Pregnancy Outcomes and Nutrition (APrON) study are to: (1) determine the relationship between maternal nutrient intake and status before, during, after pregnancy, and (a) maternal mental health, (b) pregnancy and birth outcomes, and (c) infant/child neurodevelopment and behavior; (2) identify maternal mental health and nutrient predictors of child behaviour; and (3) establish a DNA biobank to explore genomic predictors of children's neurodevelopment and behavior. The purpose of this paper is to describe the participants, measures, and key findings on maternal and paternal mental health, maternal nutrition, and child outcomes to when children are 3 years of age.

PARTICIPANTS

Participants included mothers and their children (n=2189) and mothers' partners (usually fathers; n=1325) from whom data were collected during the period from pregnancy to when children were 3 years of age, in Alberta, Canada. More than 88% of families have been retained to take part in completed data collection at 8 years of age.

FINDINGS TO DATE

Data comprise: questionnaires completed by pregnant women/mothers and their partners on mothers', fathers' and children's health; dietary interviews; clinical assessments; linkage to hospital obstetrical records; and biological samples such as DNA. Key findings on mental health, nutrition and child outcomes are presented. APrON women who consumed more selenium and omega-3 were less likely to develop symptoms of perinatal depression. Higher prenatal consumption of choline rich foods such as eggs and milk were recommended as was vitamin D supplementation for both mothers and children to meet guidelines. Couples in which both mothers and fathers were affected by perinatal depression reported lower incomes and higher maternal prenatal depressive symptoms and lower support from fathers postnatally and their children presented with the most behavioural problems. Maternal experiences of early adversity predicted increased likelihood of perinatal depression and anxiety and children's behavioural problems.

FUTURE PLANS

The APrON cohort offers a unique opportunity to advance understanding of the developmental origins of health and disease. There is a planned follow-up to collect data at 12 years of age.

Stronger functional network connectivity and social support buffer against negative affect during the COVID-19 outbreak and after the pandemic peak

Health and financial uncertainties, as well as enforced social distancing, during the COVID-19 pandemic have adversely affected the mental health of people. These impacts are expected to continue even after the pandemic, particularly for those who lack support from family and friends. The salience network (SN), default mode network (DMN), and frontoparietal network (FPN) function in an interconnected manner to support information processing and emotional regulation processes in stressful contexts. In this study, we examined whether functional connectivity of the SN, DMN, and FPN, measured using resting-state functional magnetic resonance imaging before the pandemic, is a neurobiological marker of negative affect (NA) during the COVID-19 pandemic and after its peak in a large sample (N = 496, 360 females); the moderating role of social support in the brain-NA association was also investigated. We found that participants reported an increase in NA during the pandemic compared to before the pandemic, and the NA did not decrease, even after the peak period. People with higher connectivity within the SN and between the SN and the other two networks reported less NA during and after the COVID-19 outbreak peak, and the buffer effect was stronger if their social support was greater. These findings suggest that the functional networks that are responsible for affective processing and executive functioning, as well as the social support from family and friends, play an important role in protecting against NA under stressful and uncontrollable situations.

Association of Maternal Stress and Social Support During Pregnancy With Growth Marks in Children's Primary Tooth Enamel

IMPORTANCE

Exposure to maternal psychosocial stressors during the prenatal and perinatal periods can have major long-term mental health consequences for children. However, valid and inexpensive biomarkers are currently unavailable to identify children who have been exposed to psychosocial stress and the buffers of stress exposure.

OBJECTIVE

To assess whether a growth mark in tooth enamel, the neonatal line, is associated with exposure to prenatal and perinatal maternal psychosocial factors.

DESIGN, SETTING, AND PARTICIPANTS

This prospective cohort study used exfoliated primary canine teeth and epidemiological survey data from 70 children enrolled in the Avon Longitudinal Study of Parents and Children, a birth cohort based in Bristol, England. Exfoliated teeth were collected from children at 5 to 7 years of age. Data were collected from January 1, 1991, to December 31, 1998, and were analyzed from January 1, 2019, to August 10, 2021.

EXPOSURES

Four types of prenatal and perinatal maternal psychosocial factors were studied: stressful life events, psychopathological history, neighborhood disadvantage, and social support. Data were collected from mailed-in questionnaires completed during and shortly after pregnancy.

MAIN OUTCOMES AND MEASURES

Neonatal line width measured within 3 portions of the tooth crown (the cuspal, middle, and innermost third) in exfoliated primary canines.

RESULTS

A total of 70 children (34 of 70 [48.7%] male; 63 of 67 [94.0%] White) were studied. Most children were born full term (57 [83.8%]) and to mothers of typical child-bearing age (60 [88.2%]). Neonatal lines were wider in the canines of children born to mothers who self-reported severe lifetime depression (β = 3.35; 95% CI, 1.48-5.23; P = .001), any lifetime psychiatric problems (β = 2.66; 95% CI, 0.92-4.41; P = .003), or elevated anxiety or depressive symptoms at 32 weeks' gestation (β = 2.29; 95% CI, 0.38-4.20; P = .02). By contrast, neonatal lines were narrower in children born to mothers who self-reported high social support shortly after birth (β = -2.04; 95% CI, -3.70 to -0.38; P = .02). The magnitude of these associations was large, up to 1.2 SD unit differences, and persisted after adjusting for other risk factors.

CONCLUSIONS AND RELEVANCE

In this cohort study, neonatal line width was associated with exposure to maternal perinatal psychosocial factors. Replication and validation of these findings can further evaluate teeth as possible new biomarkers.

Longitudinal effects of perinatal social support on maternal depression: a marginal structural modelling approach

BACKGROUND

Depression in the perinatal period, during pregnancy or within 1 year of childbirth, imposes a high burden on women with rippling effects through her and her child's life course. Social support may be an important protective factor, but the complex bidirectional relationship with depression, alongside a paucity of longitudinal explorations, leaves much unknown about critical windows of social support exposure across the perinatal period and causal impacts on future depressive episodes.

METHODS

This study leverages marginal structural models to evaluate associations between longitudinal patterns of perinatal social support and subsequent maternal depression at 6 and 12 months postpartum. In a cohort of women in rural Pakistan (n=780), recruited in the third trimester of pregnancy and followed up at 3, 6 and 12 months postpartum, we assessed social support using two well-validated measures: the Multidimensional Scale of Perceived Social Support (MSPSS) and the Maternal Social Support Index (MSSI). Major depressive disorder was assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM IV).

RESULTS

High and sustained scores on the MSPSS through the perinatal period were associated with a decreased risk of depression at 12 months postpartum (0.35, 95% CI: 0.19 to 0.63). Evidence suggests the recency of support also matters, but estimates are imprecise. We did not find evidence of a protective effect for support based on the MSSI.

CONCLUSIONS

This study highlights the protective effect of sustained social support, particularly emotional support, on perinatal depression. Interventions targeting, leveraging and maintaining this type of support may be particularly important for reducing postpartum depression.

Prevalence and determinants of low social support during pregnancy among Australian women: a community-based cross-sectional study

Background

Pregnancy is a time for women in which the need for social support is crucial. Social support reduces stressors and improves the emotional and physical well-being of pregnant women. Women receiving low social support during pregnancy are at risk of substances use, developing mental illness, and adverse birth outcomes. The current study aims to determine the prevalence and determinants of low social support during pregnancy among Australian women.

Methods

Data were obtained from the 1973–1978 cohort of Australian Longitudinal Study on Women’s Health (ALSWH) and those who report being pregnant (n = 493) were included in the current analyses. Social support was assessed using Medical Outcomes Study Social Support index (MOSS). A logistic regression model was applied to identify determinants of low social support, separately for each MOSS domain.

Result

The study found that 7.1% (n = 35) of pregnant women reported low social support. Significant determinants of low emotional support were non-partnered (AOR = 4.4, 95% CI: 1.27, 14.99), difficulty managing on available income (AOR = 3.1, 95% CI: 1.18, 8.32), experiencing depressive symptoms (AOR = 8.5, 95% CI: 3.29, 22.27) and anxiety symptoms (AOR = 2.9, 95% CI: 1.26, 7.03). Significant determinants of low affectionate support were suffering from depressive symptoms (AOR = 5.3, 95% CI: 1.59, 17.99), having anxiety symptoms (AOR: 6.9, 95% CI: 2.21, 22.11) and being moderately/very stressed (AOR: 3, 95% CI: 1.17, 7.89). Significant determinants of low tangible support were difficulty managing available income (AOR = 3, 95% CI: 1.29, 6.95), and being depressed (AOR = 2.8, 95% CI: 1.48, 5.34).

Conclusion

The study revealed that 7.1% of pregnant women reported low social support. Having a mental health problems, being stressed, being from low socio-economic status and being non-partnered were significant determinants of low social support during pregnancy. Maternal health professionals and policymakers can use this information to screen pregnant women at risk of receiving low social support and improve the level of support being provided.

Providing strong social support improves emotional and physical well-being, strengthens social relationships, promotes health, and enhances the stress coping ability of pregnant women. However, pregnant women receiving low social support are at risk of substances use, developing mental illness, and adverse birth outcomes. The current study aims to determine the prevalence and determinants of low social support during pregnancy among Australian women. Data were obtained from Survey 6 of the 1973–1978 cohort of the Australian Longitudinal Study on Women’s Health (ALSWH) (n = 493, pregnant women aged 34–39 years). This cohort is one of ALSWH ongoing community-based study focusing on the health of women in Australia. Social support provided for a pregnant woman was the outcome variable, assessed using the 19-item Medical Outcomes Study Social Support index (MOSS). The prevalence of low social support in each domain was calculated for each of the independent variables. A logistic regression model, using a backward stepwise elimination approach, was employed to identify determinants of low social support. In the final model, the strength of association measured by adjusted odds ratios (AOR) with 95% confidence intervals. The significance level was set at p < 0.05. From the total participant pregnant women, 7.1% of them reported low social support. Significant determinants of low social support among pregnant Australian women were, having a mental illness, being stressed and/or being from low socio-economic status and being non-partnered. Maternal health professionals can use this information to screen pregnant women at risk of receiving low social support as well as develop policy to help enhance the social support being given and the psychological wellbeing being of pregnant women.

Covariation of psychobiological stress regulation with valence and quantity of social interactions in everyday life: disentangling intra- and interindividual sources of variation

While the overall effects of social relationships on stress and health have extensively been described, it remains unclear how the experience of social interactions covaries with the activity of psychobiological stress in everyday life. We hypothesized that the valence as well as quantitative characteristics of social interactions in everyday life would attenuate psychobiological stress. Sixty healthy participants provided data for the analyses. Using an ecological momentary assessment design, participants received 6 prompts on their smartphone for 4 days. At each prompt, they reported on social interactions since the last prompt (any occurrence, frequency, duration, quality, and perceived social support), current subjective stress, and provided one saliva sample for the analyses of cortisol (sCort) and alpha-amylase (sAA). Experiencing any contact within days as well as higher daily levels of contact quality and perceived social support were associated with reduced levels of sCort. Furthermore, on a daily level, experiencing at least one contact in-between prompts more often as well as having more contacts on average attenuated the sAA output. Perceived social support and contact quality as well as higher daily contact durations were associated with lower subjective stress. For sCort, daily levels of stress moderated the effects of experiencing any contact within days while daily perceived social support moderated the effects of subjective stress. For sAA, experiencing at least one contact in-between prompts more often on a daily level moderated the effects of subjective stress. There were no between-person effects throughout all analyses. The results show ecologically valid evidence for direct attenuating effects of social interactions on psychobiological stress as well as for the stress-buffering hypothesis in everyday life. Increasing the quantity and improving the valence of social interactions on an intrapersonal level can possibly reduce psychobiological stress and prevent its consequences.

The Psychological Impact of the COVID-19 Pandemic on Pregnant Women

BACKGROUND

The COVID-19 pandemic has meant significant precautions and changes in delivering healthcare services. The aim of the study was to explore the lifestyle changes of pregnant women during the COVID-19 pandemic in Romania, the changes in prenatal care and delivery during the pandemic and the psychological impact on women and to determine how healthcare providers can help them to overcome this period.

METHODS

A cross-sectional survey was conducted anonymously and distributed among pregnancy-related groups from Romania, recruiting 559 study participants, between May and October 2020. A total of 559 pregnant women completed an online 26-item questionnaire but we only validated 557 responses for study. The survey included basic demographic questions, pregnancy-related questions, questions regarding the pregnant women's lifestyle changes during the pandemic and their perception of the COVID-19 pandemic and questions which evaluated the impact of the pandemic on prenatal care and delivery in Romania.

RESULTS

The pandemic restrictions affected women's routine activities regarding professional, familial and social life. Therefore, for pregnant women who were emotionally vulnerable, these restrictions had a great impact on their mental health. The majority of the study participants (78.8%, N = 439) were emotionally affected by the pandemic. The fear related to the possibility of having their pregnancy affected by the virus was dominant in the group (45.8%). A high number of women (69.5%) felt safe when they accessed health services, but private hospitals were considered safer (53.1%) compared to public hospitals (14.4%). The majority of participants (53.7%) used to have prenatal care in a private healthcare system. During the pandemic, preventive measures were associated with low confidence in the healthcare system. Of the total group of participants, 123 women (22.1%) gave birth during the pandemic. Of these, a majority of the study participants considered that it was very difficult for them to cope without their partner during the hospitalization and labor period.

CONCLUSIONS

The main anxiety of pregnant women were related to threats to their lives and their baby's health because of the uncertainty caused by pandemic. It is important to know that the restrictions and the changes in maternity care had a negative impact on them. This conclusion must be taken into account when preventive measures will be decided for helping them to get through such a period. Additionally, psychological support will be essential for improving the mental health of pregnant women and for preventing a negative outcome of the pregnancy. These feelings must be taken into account when preventive measures will be established during pandemic and a psychological support will be essential for improving their mental health for preventing negative outcome of pregnancy.

Social Network and Behavioral Synchrony Influences On Maternal and Infant Cortisol Response

This study examined the contributions of mothers' social network stability and mother-infant behavioral synchrony on cortisol response in infants and their mothers during separation. The quality and stability of mothers' social network system and mother-infant bond have both been shown to affect infant neuroendocrine response. Yet, no studies have directly addressed how these two forms of social relationships might differentially affect infants' and mothers' neuroendocrine responses during separation. First-time mothers (N = 133) and their 3-month-old infants participated in the study. Maternal social network stability, mother-infant behavioral synchrony, and mother and infant cortisol response during an infant challenge task were assessed. Behavioral synchrony accounted for significant variance in infants' cortisol response, and after adjusting for synchrony, mothers' network stability measures did not explain variance in infant cortisol. Social network stability, but not synchrony, accounted for significant variance in mothers' cortisol response. These results demonstrate that, when mothers and infants experience brief separation, the quality of their bond is associated with a lower stress response for infants; but for mothers, it is the longevity of her social relationships outside of the mother-infant relationship context that is associated with her lower stress response.

Associations among childhood threat and deprivation experiences, emotion dysregulation, and mental health in pregnant women

OBJECTIVE

Women who have experienced childhood maltreatment are at increased risk for experiencing mental health problems. When these occur during pregnancy, they are associated with birth complications and worse developmental outcomes for children. Emotion dysregulation (ED) may be an important, and potentially modifiable, mechanism that links women's maltreatment experiences with their mental health. However, there is limited information about the emotion regulation skills of pregnant women to guide treatment. The current study examines the unique effects of childhood threat (physical, sexual, and emotional abuse and exposure to violence) and deprivation (physical and emotional neglect and separation from primary caregivers) experiences on pregnant women's ED, posttraumatic stress and negative emotional symptoms, and social support.

METHOD

Two hundred forty-three women were recruited from an urban prenatal care clinic, the majority of whom identified as Latinx (80%) and low-income (90%). The mean age of the women was 27 years (SD = 5.5).

RESULTS

Structural equation modeling revealed significant indirect pathways from childhood threat experiences to posttraumatic stress and negative emotional symptoms via women's ED. In contrast, childhood deprivation experiences were associated with inattention to one's emotions and low perceived social support.

CONCLUSIONS

These results underscore the importance of identifying women during pregnancy who may be at risk for ED or emotional inattentiveness due to childhood maltreatment experiences and providing prevention and intervention efforts aimed at enhancing their emotional awareness and regulation.

Protocol for the Pregnancy During the COVID-19 Pandemic (PdP) Study: A Longitudinal Cohort Study of Mental Health Among Pregnant Canadians During the COVID-19 Pandemic and Developmental Outcomes in Their Children

BACKGROUND

The COVID-19 pandemic and countermeasures implemented by governments around the world have led to dramatically increased symptoms of depression and anxiety. Pregnant individuals may be particularly vulnerable to the negative psychological effects of COVID-19 public health measures because they represent a demographic that is most affected by disasters and because pregnancy itself entails significant life changes that require major psychosocial and emotional adjustments.

OBJECTIVE

The PdP study was designed to investigate the associations among exposure to objective hardship caused by the pandemic, perceived stress and psychological distress in pregnant individuals, and developmental outcomes in their offspring.

METHODS

The PdP study comprises a prospective longitudinal cohort of individuals who were pregnant at enrollment, with repeated follow-ups during pregnancy and the postpartum period. Participants were eligible if they were pregnant, ≥17 years old, at ≤35 weeks of gestation at study enrollment, living in Canada, and able to read and write in English or French. At enrollment, participants completed an initial survey that assessed demographic and socioeconomic characteristics, previous pregnancies and births, prepregnancy health, health conditions during pregnancy, medications, psychological distress, social support, and hardships experienced because of the COVID-19 pandemic (eg, lost employment or a loved one dying). For the first three months following the initial survey, participants received a monthly email link to complete a follow-up survey that asked about their experiences since the previous survey. After three months, follow-up surveys were sent every other month to reduce participant burden. For each of these surveys, participants were first asked if they were still pregnant and then routed either to the next prenatal survey or to the delivery survey. In the postpartum period, surveys were sent at 3, 6, and 12 months of infant age to assess maternal stress, psychological distress, and infant development.

RESULTS

Participant recruitment via social media (Facebook and Instagram) began on April 5, 2020, and is ongoing. As of April 2021, more than 11,000 individuals have started the initial survey. Follow-up data collection is ongoing.

CONCLUSIONS

This longitudinal investigation seeks to elucidate the associations among hardships, maternal psychological distress, child development during the COVID-19 pandemic, and risk and resilience factors that amplify or ameliorate these associations. The findings of this study are intended to generate knowledge about the psychological consequences of pandemics on pregnant individuals and point toward prevention and intervention targets.

Psychosocial status modifies the effect of maternal blood metal and metalloid concentrations on birth outcomes

BACKGROUND

Metal exposure and psychosocial stress in pregnancy have each been associated with adverse birth outcomes, including preterm birth and low birth weight, but no study has examined the potential interaction between them.

OBJECTIVES

We examined the modifying effect of psychosocial stress on the association between metals and birth outcomes among pregnant women in Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) birth cohort study.

METHODS

In our analysis of 682 women from the PROTECT study, we measured 16 essential and non-essential metals in blood samples at two time points. We administered questionnaires to collect information on depression, perceived stress, social support, and life experience during pregnancy. Using K-means clustering, we categorized pregnant women into one of two groups: "good" and "poor" psychosocial status. We then evaluated whether the effect of blood metals (geometric average) on adverse birth outcomes (gestational age, preterm birth [overall and spontaneous], birth weight z-score, small for gestation [SGA], large for gestation [LGA]) vary between two clusters of women, adjusting for maternal age, maternal education, pre-pregnancy body mass index (BMI), and second-hand smoke exposure.

RESULTS

Blood manganese (Mn) was associated with an increased odds ratio (OR) of overall preterm birth (OR/interquartile range [IQR] = 2.76, 95% confidence interval [CI] = 1.25, 6.12) and spontaneous preterm birth (OR/IQR: 3.68, 95% CI: 1.20, 6.57) only among women with "poor" psychosocial status. The association between copper (Cu) and SGA was also statistically significant only among women having "poor" psychosocial status (OR/IQR: 2.81, 95% CI: 1.20, 6.57). We also observed associations between nickel (Ni) and preterm birth and SGA that were modified by psychosocial status during pregnancy.

CONCLUSIONS

Presence of "poor" psychosocial status intensified the adverse associations between Mn and preterm birth, Cu and SGA, and protective effects of Ni on preterm. This provides evidence that prenatal psychosocial stress may modify vulnerability to metal exposure.

Cortisol and estriol responses to awakening in the first pregnancy trimester: Associations with maternal stress and resilience factors

BACKGROUND

Little is known about the maternal cortisol awakening response (CAR) in the first pregnancy trimester. Similarly unknown is how the CAR in early gestation relates to other steroid hormones, such as estriol. Maternal estriol in blood and urine is used to monitor fetal well-being since it is produced by the fetoplacental unit from fetal precursors. Low levels have been associated with maternal-fetal complications. We were recently able to show that estriol is measurable in maternal saliva from 6 weeks' gestation onwards. However, its pattern following morning awakening and potential links with salivary cortisol in early gestation is relatively unknown. In this prospective study, we explored the cortisol and estriol responses to morning awakening in first-trimester pregnant women, the potential association of these endocrine variables with maternal stress and resilience factors, and their predictive value for the further pregnancy course.

METHODS

Fifty-one women with an uncomplicated, singleton pregnancy responded to questionnaires measuring chronic and pregnancy-specific stress, emotional support, and daily uplifts at 6 weeks' gestation. At 8 and 10 weeks, the women collected saliva samples immediately, 30, and 60 min after morning awakening. After 12 weeks, 40 women reported on the further pregnancy course, of whom 6 had developed complications.

RESULTS

In response to morning awakening, cortisol levels increased significantly at 10 weeks (p = .04), while estriol levels decreased significantly at both 8 and 10 weeks (p < .001). A stronger cortisol increase was linked to a stronger estriol decrease at 8 (p = .03), but not at 10 weeks. Then, perceived emotional support at 6 weeks was negatively associated with cortisol baseline at 8 (p = .01) and positively with estriol baseline at 10 weeks (p = .03). Moreover, higher pregnancy-specific stress was related to a lower estriol baseline at 8 weeks (p = .047). Furthermore, compared to healthy women, those with complications at follow-up had already reported less emotional support (p = .03) and fewer daily uplifts (p = .03) at 6 weeks. These women also seemed to lack a significant estriol response to morning awakening at 8 weeks (p > .10).

DISCUSSION

These findings advance our knowledge of cortisol and estriol secretion following morning awakening and encourage the investigation of E3 in addition to cortisol when researching prenatal stress and its consequences for maternal and fetal health.

Association between maternal employment status during pregnancy and risk of depressive symptomatology 1 month after childbirth: the Japan Environment and Children's Study

BACKGROUND

Previous studies, which examined the association between employment status and postpartum depression, were limited by binary or ternary employment status measures (employed/unemployed or full-time/part-time/unemployed). This study examined the association between detailed employment status during pregnancy and risk of depressive symptomatology 1 month after childbirth, and the effect modification by one's perceived level of social support and household equivalent income.

METHODS

Our study examined 76 822 participants in the Japan Environment and Children's Study. The exposure included maternal employment status during pregnancy (regular workers, dispatched workers, part-time workers, self-employed workers, non-employed and others), and the outcome was depressive symptomatology 1 month after childbirth: Edinburgh Postnatal Depression Scale (EPDS scores ≥9 and ≥13). Adjusted ORs and 95% CIs of depressive symptomatology associated with employment status were calculated by multivariable logistic regression. Subgroup analyses by perceived level of social support and household equivalent income were conducted.

RESULTS

Compared with regular workers, the risk of depressive symptomatology (EPDS score ≥9) was higher for non-employed and others, and that (EPDS score ≥13) was so for part-time workers. There was no significant interaction by perceived level of social support and household equivalent income in the associations. However, part-time workers and non-employed had excess risk of depressive symptomatology among women with lower perceived level of social support, but not among those with the higher one.

CONCLUSION

Compared with regular workers, part-time workers and non-employed had an increased risk of depressive symptomatology, which was confined to women with lower perceived level of social support.

The relationship between psychosocial health status and social support of pregnant women

PURPOSE

The aim of this study was to determine the relationship between psychosocial health status and social support, which has important effects on pregnancy, and to determine the factors related to both psychosocial health and social support.

METHOD

The research was planned to be a descriptive study. The sample of the study consisted of 393 pregnant women. 'Personal Information Form', 'Pregnancy Psychosocial Health Assessment Scale (PPHAS)', and 'Multidimensional Scale of Perceived Social Support (MSPSS)' were used to collect data, and Student's t-test, ANOVA and Tukey's HSD tests were used for the data analysis. The relationship between the two continuous variables was evaluated according to the Pearson correlation coefficient.

RESULTS

Psychosocial health conditions and perceived social supports of pregnant women whose spouses were working were determined to be significantly higher (p < .05), and at a lower level (p < .05) in pregnant women with two or more children. As MSPSS total mean scores of the pregnant women increased, their PPHAS total mean scores were weakly affected in the positive direction (r = 0.393, p < .01).

CONCLUSIONS

It is recommended that health care needs of pregnant women should be evaluated not only in terms of physical health but also together with their psychosocial health and social supports. Furthermore, this assessment should be done in their own home environment with their spouses and other family members.

Elevated depression and anxiety symptoms among pregnant individuals during the COVID-19 pandemic

BACKGROUND

Anxiety and depression symptoms in pregnancy typically affect between 10 and 25% of pregnant individuals. Elevated symptoms of depression and anxiety are associated with increased risk of preterm birth, postpartum depression, and behavioural difficulties in children. The current COVID-19 pandemic is a unique stressor with potentially wide-ranging consequences for pregnancy and beyond.

METHODS

We assessed symptoms of anxiety and depression among pregnant individuals during the current COVID-19 pandemic and determined factors that were associated with psychological distress. 1987 pregnant participants in Canada were surveyed in April 2020. The assessment included questions about COVID-19-related stress and standardized measures of depression, anxiety, pregnancy-related anxiety, and social support.

RESULTS

We found substantially elevated anxiety and depression symptoms compared to similar pre-pandemic pregnancy cohorts, with 37% reporting clinically relevant symptoms of depression and 57% reporting clinically relevant symptoms of anxiety. Higher symptoms of depression and anxiety were associated with more concern about threats of COVID-19 to the life of the mother and baby, as well as concerns about not getting the necessary prenatal care, relationship strain, and social isolation due to the COVID-19 pandemic. Higher levels of perceived social support and support effectiveness, as well as more physical activity, were associated with lower psychological symptoms.

CONCLUSION

This study shows concerningly elevated symptoms of anxiety and depression among pregnant individuals during the COVID-19 pandemic, that may have long-term impacts on their children. Potential protective factors include increased social support and exercise, as these were associated with lower symptoms and thus may help mitigate long-term negative outcomes.

Ecological momentary assessment of stress, racism and other forms of discrimination during pregnancy using smartphone technology

BACKGROUND

In the United States, there are considerable racial inequities in adverse perinatal outcomes. Exposure to racism, sexism, and other forms of oppression may help explain these inequities.

OBJECTIVES

To describe the application of real-time data collection using ecological momentary assessment (EMA) and smartphone technology to assess exposure to stress, racism, sexism, microaggressions, and other forms of oppression.

METHODS

The Postpartum Mothers Mobile Study (PMOMS) is an ongoing longitudinal cohort study that began recruitment in December 2017. Participants delivering at a hospital in Pittsburgh, PA are recruited by 29 weeks' gestation. Using smartphones and smart scales, participants complete daily surveys related to psychosocial, behavioural, and contextual factors and weigh themselves weekly for approximately 15 months. We provide a preliminary descriptive analysis of EMA self-reported measures of stress, racism, sexism, and microaggressions; and non-EMA measures of stress and major discrimination.

RESULTS

The sample (n = 230) is 63.5% White, 24.8% Black/African American, and 7% Hispanic origin. The most commonly reported item from the Major Discrimination Scale is being unfairly fired (18.1% of the sample). Of those, 31.7% and 17.1% attribute unfair firing to their gender and race, respectively. From the random EMA measures, on average, participants report experiences of racism and sexism at least once daily, in an average 12-hour day over the 4-week period. Black participants indicate about two experiences per day of racism, and White participants indicate more than 1 per day of sexism. Mean stress levels from the EMA measures were similar to the stress measures collected at baseline.

CONCLUSIONS

The methods applied in PMOMS provide real-time data regarding how participants' daily experiences of stress and discrimination influence their lives. Future work will include understanding if and how these EMA measures may relate to already established measures of racism, sexism, and stress; and ultimately understanding associations with perinatal inequities.

Prevalence of depression symptoms and its influencing factors among pregnant women in late pregnancy in urban areas of Hengyang City, Hunan Province, China: a cross-sectional study

OBJECTIVES

To evaluate the prevalence of depressive symptoms and its influencing factors in late pregnancy.

DESIGN

Cross-sectional study.

SETTING

Fourteen community in urban areas of Hengyang City.

PARTICIPANTS

The study conducted from July to October 2019, and surveyed 813 women in late pregnancy who lived in urban areas of Hengyang for more than 6 months, signed an informed consent and were without cognitive disorders, severe mental illnesses or other serious diseases.

MEASURES

Perinatal depression symptoms were evaluated using the Patient Health Questionnaire-9, and perinatal anxiety symptoms were evaluated using the Generalised Anxiety Disorder-7 Scale. Sociodemographic variables, obstetric characteristics, lifestyle behaviours, family factors, social support, sleep quality and self-efficacy were obtained through structured questionnaires.

RESULTS

The prevalence of depression symptoms among pregnant women in late pregnancy was 9.2% (95% CI 7.2%-11.2%). Protective factor: age between 25 and 29 years (OR=0.398; 95% CI 0.16-0.991).

RISK FACTORS

a normal relationship with her mother-in-law (OR=5.309; 95% CI 1.122-4.184), artificial insemination (OR=4.339; 95% CI 1.492-12.623), no exercise during pregnancy (OR=2.666; 95% CI 1.177-6.039), low self-efficacy (OR=4.253; 95% CI 1.518-11.916), low social support (OR=2.371; 95% CI 1.206-4.661), poor sleep quality (OR=2.134; 95% CI 1.131-4.027), existence of anxiety symptoms (OR=17.654; 95% CI 8.494-36.689).

CONCLUSION

The prevalence of depression symptoms is lower than that in developing countries, but due to the large population base of China, the problem should still be taken seriously. To prevent mental disorders of pregnant women, early screening for mental disorders, promotion of healthy lifestyles, mental healthcare during pregnancy and improved family and social support should be implemented during pregnancy nursing.

Perceived social support moderates neural reactivity to emotionally valenced stimuli during pregnancy

Reactivity to emotional information, measurable at the level of neural activity using event-related potentials, is linked to symptoms of affective disorders. Behavioral evidence suggests that contextual factors, such as social support, can alter emotional reactivity such that affective responding is normalized when social support is high. This possibility remains largely untested at the neural level, specifically through approaches that can offer insight into the mechanistic processes contributing to individual differences in emotional reactivity. Yet, such knowledge could be useful for prevention and intervention efforts, particularly with groups at risk for increased emotional reactivity, such as pregnant mothers for whom emotional distress predicts both maternal and child outcomes. Expectant mothers took part in a longitudinal study that tested whether the late positive potential (LPP), a neural index of reactivity to emotional information, was moderated by maternal perceptions of social support. In the third trimester of pregnancy, lower perceived social support was associated with an absence of a traditional LPP effect, which differentiates valenced from neutral stimuli. Findings suggest that perceptions of social support may normalize emotional processing at the neural level and highlight the potential importance of social support modulation of emotional reactivity during times of known biological change.

Attachment & Child Health (ATTACH) pilot trials: Effect of parental reflective function intervention for families affected by toxic stress

Toxic stressors (e.g., parental violence, depression, low income) place children at risk for insecure attachment. Parental reflective function-parents' capacity to understand their own and their child's mental states and thus regulate their own feelings and behavior toward their child-may buffer the negative effects of toxic stress on attachment. Our objective was to test the effectiveness of the Attachment and Child Health (ATTACH) intervention, focusing on improving reflective function and children's attachment security, for at-risk mothers and children <36 months of age. Three pilot studies were conducted with women and children from an inner city agency serving vulnerable, low-income families and a family violence shelter. Randomized control trial (n = 20, n = 10 at enrollment) and quasi-experimental (n = 10 at enrollment) methods tested the effect of the ATTACH intervention on the primary outcome of reflective function scores, from transcribed Parent Development Interviews. Our secondary outcome was children's attachment patterns from Ainsworth's Strange Situation Procedure. Despite some attrition, mixed methods analysis of covariance and t tests revealed significant differences in maternal, child, and overall reflective function, with moderate effect sizes. While more children whose mothers received the ATTACH program were securely attached posttreatment, as compared with controls, significant differences were not observed, which may be due to missing observations (n = 5 cases). Understanding the effectiveness of programs like the ATTACH intervention contributes to improved programs and services to promote healthy development of children affected by toxic stress.

Oxytocin and the stress buffering effect of social company: a genetic study in daily life

Social relationships are a crucial determinant of both mental and physical health. This effect is partly due to social buffering of stress. Animal studies suggest that social buffering is mediated via the oxytocin system, while studies in humans are sparse and limited by the low ecological validity of laboratory settings. In the present study, participants (N = 326) completed smartphone questionnaires four times a day over 4 to 5 days, measuring stressors, negative affect, and social context to assess social buffering. We found that under stress, participants reported a higher need for social company. Further, the impact of prior stressful events on momentary negative affect was attenuated by the perceived pleasantness of current social company. This social buffering effect was moderated by haplotypes of the oxytocin receptor gene, based on two well-described single nucleotide polymorphisms (rs2268498, rs53576). Effects were robust when controlling for gender and age, applying different data quality criteria, and even apparent in genotype-based analyses. Our findings demonstrate that social buffering and its modulation by oxytocin system characteristics have implications for life as lived outside the laboratory.

Discrimination Increases the Association Between Parental and Adolescent Allostatic Load in Chinese Rural-to-Urban Migrants

PURPOSE

This study was designed to examine the extent to which parents' allostatic load (AL) and adolescents' perceived discrimination are interrelated in the prediction of adolescents' AL among rural-to-urban migrants in China, as well as the possible buffering role of social support.

METHODS

Multi-informant data were collected in this study. A total of 158 rural-to-urban migrant adolescents (Mean_age = 11.62 years) and one of each of their parents (Mean_age = 39.84 years) were recruited from the suburbs of Beijing, China. Both adolescents' and parents' AL scores were based on 10 physiological indices. Migrant adolescents were asked to report their perceived discrimination and social support.

RESULTS

Parents' AL was significantly positively related to adolescents' AL. The relationship between parents' and adolescents' AL was stronger among adolescents reporting higher perceived discrimination than among those reporting lower. Social support moderated the adverse effects of parents' AL and perceived discrimination on adolescents' AL. Specifically, among adolescents reporting higher social support, the relationships between parents' and adolescents' AL were not significant for those with either high or low perceived discrimination. However, among adolescents reporting lower social support, the positive association was significant for those with high perceived discrimination but not for those with low perceived discrimination.

CONCLUSIONS

Parents' AL was a strong predictor of migrant adolescents' AL, and perceived discrimination acted as a catalyst to increase the association. The relationships of parental AL and perceived discrimination with AL were not significant for adolescents who received high social support.

Supportive Social Interactions in Infertility Treatment Decrease Cortisol Levels: Experimental Study Report

PURPOSE

The aim of the research project was to analyze the importance of supportive social interactions in the process of infertility treatment. The acceptance rates of ART (Assisted Reproductive Technology) in Poland are lower than in western European countries and the social stigma of infertility exists. The research project draws attention to the issue of disclosure of fertility problems and the ability to seek support in Polish couples.

METHODS

An experimental study was conducted with 51 heterosexual couples who qualified for IVF. The participants were randomly divided into an experimental and control group. The first stage of the research procedure, with all the couples, was to extract a saliva (cortisol) sample as a biomarker for stress. In the second stage the control group viewed an informational (non-emotional) video about human embryology. The experimental group took part in a supportive social interaction process. In the supportive social interaction process, a maximum of five couples, were led through a broad general understanding of their IVF experience by an experienced group psychologist. The third stage of the research involved the second extraction of a saliva (cortisol) sample form all participants. In addition, demographic and medical history related to fertility was collected.

RESULTS

The statistical analysis indicates a significant decrease in the level of stress experienced after the supportive social interaction. The reported differences between the experimental group and the control group indicated a larger decrease of cortisol level for women and men.

CONCLUSION

In the current study, the hypothesis that taking part in supportive social interaction significantly lowers stress levels (measured via cortisol) of infertile couples (men and women) was supported. Further the project indicates that a supportive social interaction has a beneficial effect on infertile couple's health and well-being. The results of the study clearly point to the benefits of couples involved in infertility treatment to express and share their experience, and in doing so, provides measurable physiological and psychological benefits.

Maternal and paternal perinatal depressive symptoms associate with 2- and 3-year-old children's behaviour: findings from the APrON longitudinal study

BACKGROUND

Prenatal and postnatal depressive symptoms are common in expectant and new mothers and fathers. This study examined the association between four patterns of probable perinatal depression (mother depressed, father depressed, both depressed, neither depressed) in co-parenting mothers and fathers and their children's internalizing and externalizing behaviours at 24 and 36 months of age. The influence of sociodemographic, risk and protective factors was also examined.

METHODS

Depressive symptoms were measured during pregnancy and at 3 months postpartum and children's behaviour was assessed at 24 and 36 months of age. Families (n = 634) provided data on their children's internalizing (i.e. emotionally reactive, anxious/depressed, somatic complaints, withdrawn and total) and externalizing (i.e. attention problems, aggression and total) behaviour. Marginal models were employed to determine the relationship between children's behaviour over the two time points and the four patterns of probable parental depression. Sociodemographic variables as well as risk (stress) and protective (social support) factors were included in these models.

RESULTS

In the perinatal period 19.40% (n = 123) of mothers scored as probably depressed and 10.57% (n = 67) of fathers. In 6.31% (n = 40) of the participating families, both parents scored as probably depressed and in 63.72% (n = 404) neither parent scored as depressed. For children's emotionally reactive, withdrawn and total internalizing behaviours, both mothers' probable depression and mothers and fathers' co-occurring probable depression predicted higher scores, while for children's aggressive behaviour, attention problems, and total externalizing behaviours, only mothers' probable depression predicted higher scores, controlling for sociodemographic, risk and protective factors.

CONCLUSIONS

While probable perinatal depression in mothers predicted 2 and 3 year-old children's behavioural problems, co-occurrence of depression in mothers and fathers had an increased association with internalizing behavioural problems, after considering sociodemographic, risk and protective factors. Health care providers are encouraged to consider the whole family in preventing and treating perinatal depression.

Spontaneous Coronary Artery Dissection (SCAD): FEMALE SURVIVORS' EXPERIENCES OF STRESS AND SUPPORT

PURPOSE

Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic type of acute myocardial infarction that primarily affects young, healthy women without typical risk factors for heart disease. Few investigations have examined psychosocial variables in this population and none have looked at patient perceptions of the experience and stresses associated with having a SCAD event or the resources currently available to SCAD survivors. This investigation describes survivors' subjective experiences of SCAD. Participants also provided information about types and helpfulness of resources available to them post-SCAD, including cardiac rehabilitation.

METHODS

Participants were recruited online and completed a one-time questionnaire.

RESULTS

Participants (n = 409) completed a questionnaire concerning their experiences with their SCAD event in the 1 y and 2 wk prior to the SCAD event. Their responses reflected moderate to high perceptions of stress. Participants experienced the SCAD event as highly stressful and frightening and their heart health presents as a moderate-severe source of current, post-diagnosis stress. Spontaneous coronary artery dissection-based informational support was frequently rated as inadequate, whereas other supportive resources varied in their helpfulness and accessibility. Participants reported positive experiences in cardiac rehabilitation and strong interest in SCAD-specific, professionally led, online patient education and support groups.

CONCLUSIONS

This study is the largest to date investigation of SCAD survivors and their experiences in this understudied and perhaps underrecognized condition. Opportunities for researchers and providers to develop, tailor, and disseminate SCAD-specific interventions are discussed.

Understanding Pregnancy and Postpartum Health Using Ecological Momentary Assessment and Mobile Technology: Protocol for the Postpartum Mothers Mobile Study

Background

There are significant racial disparities in pregnancy and postpartum health outcomes, including postpartum weight retention and cardiometabolic risk. These racial disparities are a result of a complex interplay between contextual, environmental, behavioral, and psychosocial factors.

Objective

This protocol provides a description of the development and infrastructure for the Postpartum Mothers Mobile Study (PMOMS), designed to better capture women’s daily experiences and exposures from late pregnancy through 1 year postpartum. The primary aims of PMOMS are to understand the contextual, psychosocial, and behavioral factors contributing to racial disparities in postpartum weight and cardiometabolic health, with a focus on the daily experiences of stress and racism, as well as contextual forms of stress (eg, neighborhood stress and structural racism).

Methods

PMOMS is a longitudinal observation study that is ancillary to an existing randomized control trial, GDM² (Comparison of Two Screening Strategies for Gestational Diabetes). PMOMS uses an efficient and cost-effective approach for recruitment by leveraging the infrastructure of GDM², facilitating enrollment of participants while consolidating staff support from both studies. The primary data collection method is ecological momentary assessment (EMA) and through smart technology (ie, smartphones and scales). The development of the study includes: (1) the pilot phase and development of the smartphone app; (2) feedback and further development of the app including selection of key measures; and (3) implementation, recruitment, and retention.

Results

PMOMS aims to recruit 350 participants during pregnancy, to be followed through the first year after delivery. Recruitment and data collection started in December 2017 and are expected to continue through September 2020. Initial results are expected in December 2020. As of early May 2019, PMOMS recruited a total of 305 participants. Key strengths and features of PMOMS have included data collection via smartphone technology to reduce the burden of multiple on-site visits, low attrition rate because of participation in an ongoing trial in which women are already motivated and enrolled, high EMA survey completion and the use of EMA as a unique data collection method to understand daily experiences, and shorter than expected timeframe for enrollment because of the infrastructure of the GDM² trial.

Conclusions

This protocol outlines the development of the PMOMS, one of the first published studies to use an ongoing EMA and mobile technology protocol during pregnancy and throughout 1 year postpartum to understand the health of childbearing populations and enduring racial disparities in postpartum weight and cardiometabolic health. Our findings will contribute to the improvement of data collection methods, particularly the role of EMA in capturing multiple exposures and knowledge in real time. Furthermore, the results of the study will inform future studies investigating weight and cardiometabolic health during pregnancy and the postpartum period, including how social determinants produce population disparities in these outcomes.

Dynamic and bidirectional associations between maternal stress, anxiety, and social support: The critical role of partner and family support

BACKGROUND

Stress and anxiety in pregnancy and the postpartum period are associated with poor long-term maternal and child health outcomes. Social support has been shown to mitigate the effects of maternal stress and anxiety; however, the directionality and longitudinal associations among these variables are poorly understood. Using a novel multilevel modeling approach called dynamic structural equation modeling (DSEM), we examined within-person (state-level) autoregressive and cross-lagged associations among stress, anxiety, and social support in the perinatal period in order to elucidate directional associations over time.

METHODS

Mothers from a longitudinal pregnancy cohort (N = 3,388) completed self-report measures of stress, anxiety, and social support across 4 time points from pregnancy to 12 months postpartum.

RESULTS

Higher than average levels of stress and anxiety led to elevations in anxiety and stress and decreases in social support at subsequent time points. Importantly, earlier individual levels of partner and family support predicted subsequent decreases in stress and anxiety.

LIMITATIONS

Support was measured via maternal self-report thus extrapolations cannot be made to tangible or instrumental supports and lagged relationships represent average lags over time.

CONCLUSIONS

Using a novel statistical approach, these results suggest that increases in both partner and family support may be powerful protective factors for decreasing mental health difficulties in pregnancy and the postpartum, highlighting the importance of targeting and increasing this type of support from pregnancy to the postpartum period.

Ambulatory Blood Pressure Trajectory and Perceived Stress in Relation to Birth Outcomes in Healthy Pregnant Adolescents

OBJECTIVE

An early decline in resting blood pressure (BP), followed by an upward climb, is well documented and indicative of a healthy pregnancy course. Although BP is considered both an effector of stress and a clinically meaningful measurement in pregnancy, little is known about its trajectory in association with birth outcomes compared with other stress effectors. The current prospective longitudinal study examined BP trajectory and perceived stress in association with birth outcomes (gestational age (GA) at birth and birth weight (BW) percentile corrected for GA) in pregnant adolescents, a group at risk for stress-associated poor birth outcomes.

METHODS

Healthy pregnant nulliparous adolescents (n = 139) were followed from early pregnancy through birth. At three time points (13-16, 24-27, and 34-37 gestational weeks ±1 week), the Perceived Stress Scale was collected along with 24-hour ambulatory BP (systolic and diastolic) and electronic diary reporting of posture. GA at birth and BW were abstracted from medical records.

RESULTS

After adjustment for posture and pre-pregnancy body mass index, hierarchical mixed-model linear regression showed the expected early decline (B = -0.18, p = .023) and then increase (B = 0.01, p < .001) of diastolic BP approximating a U-shape; however, systolic BP displayed only an increase (B = 0.01, p = .010). In addition, the models indicated a stronger systolic and diastolic BP U-shape for early GA at birth and lower BW percentile and an inverted U-shape for late GA at birth and higher BW percentile. No effects of perceived stress were observed.

CONCLUSIONS

These results replicate the pregnancy BP trajectory from previous studies of adults and indicate that the degree to which the trajectory emerges in adolescence may be associated with variation in birth outcomes, with a moderate U-shape indicating the healthiest outcomes.

Effects of Social Support Source and Effectiveness on Stress Buffering After Stem Cell Transplant

BACKGROUND

This study used the social support effectiveness framework to examine whether effective social support buffered the relationship between stressful life events and distress among hematopoietic stem cell transplant (HSCT) survivors and whether that buffering effect depended on the type of caregiver who provided it (partner versus non-partner caregivers).

METHODS

A total of 275 HSCT survivors completed measures of the effectiveness of their caregiver's support-social support effectiveness (SSE)-distress, and stressful life events. Hierarchical linear regression was used to analyze a three-way interaction between stressful life events, caregiver SSE, and caregiver type on distress.

RESULTS

After controlling for covariates, the three-way interaction of stressful life events, caregiver SSE, and caregiver type was significant (b = - 0.21, SE = 0.00, p < 0.001). Among partnered survivors, more stressful life events were associated with greater distress (B = 0.03, SE = 0.01, p = 0.045) when caregiver SSE was low. There was no association between stressful life events and distress when caregiver SSE was average (B = 0.01, SE = 0.01, p = 0.50) or high (B = - 0.01, SE = 0.02, p = 0.61). Among non-partnered survivors, there was a positive association between stressful life events and distress regardless of caregiver SSE.

CONCLUSIONS

Average or highly effective caregiver support buffered effects of stressful life events on distress among partnered survivors. There was no evidence that support at any level of effectiveness buffered stressful life events among non-partnered survivors. Findings highlight the importance of measuring social support effectiveness and source of support among HSCT survivors.

Social Support During Pregnancy Modifies the Association Between Maternal Adverse Childhood Experiences and Infant Birth Size

Introduction Adverse childhood experiences (ACEs) can deleteriously affect health, including pregnancy and birth outcomes occurring later in life. Identification of modifiable factors during pregnancy that buffer the ill effects of adversity is warranted. Social support during pregnancy can promote better birth outcomes, yet it is unknown whether it could also mitigate perinatal risks stemming from ACEs. Thus, this study considers multiple forms of social support in pregnancy as modifiers of an ACEs and fetal growth association. Methods Data were collected from mother and infant pairs from an ongoing prospective birth cohort. Women enrolled around 27 weeks gestation and completed gold-standard assessments of ACEs and social support. Infant cephalization index scores [(head circumference /birthweight) × 100; a marker of asymmetric fetal growth] were derived. Multivariable regression models tested main effects and interaction between ACEs and social support in relation to infant cephalization. Results Higher levels of ACEs were associated with higher cephalization scores (β = 0.01, SE = 0.01, p < 0.05) whereas higher social support was associated with lower cephalization scores (β = - 0.03, SE = 0.01, p < 0.05). A significant interaction was observed showing a protective effect of social support among those with low (0 events) and moderate (1-3 events) ACEs but not among those with high ACEs (4 + events; p < 0.05). Tangible and emotional support, but not information support, contributed to the associations. Discussion Maternal ACEs can deleteriously affect birth size, yet social support during pregnancy provides some buffer from its enduring effects. Interventions designed to enhance pregnancy social support may not only improve maternal wellbeing, but may also safeguard infant health.

Partner social support during pregnancy and the postpartum period and inflammation in 3-month-old infants

Prenatal social stress "programs" offspring immune activity in animal models, but how the prenatal social environment affects human offspring inflammation is not known. Here, we test associations between prenatal partner support quality, i.e. positive/helpful support, negative/upsetting support, and their interaction, and infant inflammatory markers. A sample of 113 women from the Alberta Pregnancy Outcomes and Nutrition (APrON) cohort were followed from early pregnancy to 3-months postpartum. Partner support quality was measured during pregnancy and the postpartum period. Three-month-old infant blood samples were assayed for inflammatory markers, i.e., adaptive immune markers IFNγ, IL12p70 and IL10. The prenatal positive-by-negative partner support interaction predicted infant IFNγ, IL12p70, and IL10, p's<.035, independent of covariates and postpartum partner support. When negative partner support was high, high positive support predicted higher infant IFNγ, IL12p70, and IL10. As such, partner support during pregnancy that is both highly negative/upsetting and also highly positive/helpful predicted adaptive immunity markers in infants at 3 months of age.
