Refugee or immigrant women residing in conflict prone countries portray elevated mental health related vulnerabilities during their peripartum periods and require effective interventions for improved maternal and child well-being. The objective of this systematic review is to generate evidence on effective interventions for managing peripartum mental health issues among refugee women from conflicted settings.

Systematic review.

Three databases MEDLINE/PubMed, Scopus, and Web of Science (core collection) were searched and Rayyan was used to perform screening. RoBANS tool was used to assess the risk of bias and narrative synthesis was conducted to narrate the result.

5425 potential articles were identified and seven studies were included for data extraction after a rigorous screening process. Four (n = 4), out of seven studies discussed improved Edinburgh Postnatal Depression Scale (EPDS) scores, reduced perinatal distress and depression, increased self-esteem, and knowledge about pregnancy and child development, etc. due to home visits during the antepartum and postpartum period. Two studies asserted the importance of group sessions and social support and found social support was negatively correlated with postpartum depression (r = -0.49, p < 0.0001). Formal/informal, public, private, or volunteered supports were explored to be important for increasing knowledge about maternal well-being, stress management, and childcare processes for refugee women.

The absence of limited experimental studies opens the opportunity for conducting further research on this topic. Besides, development partners can focus on this review to prioritise the intervention components during designing programmes on this related issue.

Longitudinal research assessing childhood mental health is limited, particularly in terms of tracking how early-life factors influence the development of emotional and behavioral disorders over time. The present study aimed to examine the influence of both antenatal and postnatal maternal mental health on children's emotional and behavioral development, with a focus on the trajectory of internalizing, externalizing and attention deficit hyperactivity disorder (ADHD) symptoms from early childhood through adolescence. The present study included 434 mother-child pairs of the Rhea mother-child cohort in Crete, Greece. Maternal depressive symptoms (EPDS), trait anxiety (STAI-Trait), and personality traits (EPQ-R) were assessed during the third trimester of pregnancy, while postnatal depressive symptoms (EPDS) were evaluated 8-10 weeks after childbirth. Children's internalizing, externalizing and ADHD-related symptoms were assessed at ages 4 (using the SDQ and ADHDT, respectively), and at ages 6, 11, and 15 (using the CBCL and CPRS-R:S, respectively). Multivariate mixed regression models, incorporating a random intercept for each child and a random slope for age at follow-up, were used to analyze the trajectories of symptoms from ages 4 to 15. Significant long-term associations were found between maternal mental health and child outcomes between the ages of 4 and 15. Specifically, higher levels of maternal trait anxiety and neuroticism were associated with an increase in children's internalizing, externalizing, and ADHD symptoms. Both antenatal and postnatal maternal depressive symptoms were linked to a greater likelihood of internalizing and externalizing symptoms over time, but only postnatal depression was related to a rise in ADHD symptoms. The findings emphasize the importance of perinatal maternal mental health in children's emotional and behavioral development and suggest the need for prevention and early intervention programs to support the mental health of both mothers and children.

Polycystic ovarian syndrome (PCOS) is a common female endocrinologic condition that affects both the metabolic and reproductive systems and is the most frequent cause of anovulatory infertility. It is also associated with a range of psychiatric outcomes in individuals, including bulimia nervosa, schizophrenia, bipolar disorder, depression, anxiety, and personality disorders. At the same time, evidence suggests that hyperandrogenism, the characteristic trait of PCOS, may impair fetal neurodevelopment. Epidemiological studies have linked maternal PCOS with a variety of behavioral and psychiatric conditions in offspring including autism spectrum disorder and attention deficit hyperactivity disorder. In this review, we explore evidence for potential underlying biological mechanisms that might explain these observed associations, discuss the complex interplay between genetics and various environmental factors across generations, and highlight avenues for future research.

Mental health during pregnancy is a critical factor influencing maternal and fetal outcomes. Anxiety and depression affect up to 30% of pregnant women, with significant consequences for maternal well-being and child development. Despite this, interventions during pregnancy remain limited, creating a need for innovative, accessible solutions.

This study aimed to evaluate the effectiveness of an immersive virtual reality (IVR) eHealth intervention in reducing anxiety and depression symptoms in women during pregnancy.

A 2-arm, randomized controlled trial was conducted across 5 primary care centers in Catalonia, Spain, between October 2021 and May 2024. The study included pregnant women (N=70) aged ≥18 years with moderate anxiety and depression symptoms (Edinburgh Postnatal Depression Scale [EPDS] scores: 9-12) at 12 to 14 weeks of gestation. They were randomly assigned (1:1) to an IVR intervention or standard care group. The intervention group engaged in daily 14-minute IVR mindfulness and relaxation sessions for 6 weeks. Mental health outcomes were assessed using the EPDS and State-Trait Anxiety Inventory.

The intervention group demonstrated significant reductions in EPDS scores, with a mean decrease from 11.32 (SD 0.96) to 7.25 (SD 1.32; P<.001), compared to an increase in the control group from 11.32 (SD 0.94) to 16.23 (SD 1.25; P<.001). Similarly, State-Trait Anxiety Inventory scores improved markedly in the intervention group (mean decrease from 57.94, SD 5.23 to 35.03, SD 6.12; coefficient -30.47, 95% CI -45.23 to -15.72; P<.001), while the control group experienced a nonsignificant increase (from 66.10, SD 5.89 to 72.91, SD 6.34; P=.68). High adherence rates were observed, with 79% (26/33) of participants completing ≥30 sessions. Participant satisfaction was high, with 87% (29/33) reporting being "very satisfied" with the intervention.

The IVR eHealth intervention significantly reduced symptoms of anxiety and depression, demonstrating its potential as an accessible and effective tool for mental health support during pregnancy. High adherence and satisfaction levels underscore its feasibility and acceptability. Future research should explore the long-term effects and scalability of IVR interventions in diverse settings.

Prenatal care aims to ensure the well-being of both mother and baby by closely watching for potential problems and addressing them promptly. A lack of such care often stems from a combination of issues, including financial hardship, limited education, challenges in accessing healthcare, inadequate medical services, and insufficient social support. The study aimed to assess how iron supplements given during prenatal care affect the prevalence of anemia and whether lack of prenatal care leads to increased maternal and fetal morbidity. This analysis is based on the retrospective evaluation of medical data from 125 patients admitted to the Obstetrics and Gynecology Department of Sf. Pantelimon Hospital in Bucharest, Romania, from August 2024 to February 2025. The parameters considered in this study include prenatal care access, mode of delivery, antepartum anemia and its severity, iron supplementation, postpartum anemia and the necessity of blood transfusions, and length of hospitalization. The link between prenatal care and reduced antepartum anemia underscores the importance of monitoring during pregnancy to mitigate risks. Postpartum hemoglobin levels were significantly higher in patients who received prenatal care, leading to a decrease in severe and moderate anemia cases. Additionally, prenatal care was associated with shorter hospital stays for newborns. Comprehensive prenatal care demonstrably enhanced both maternal and neonatal prognoses across the continuum of pregnancy and the puerperium, thereby contributing to a significant reduction in rates of maternal and fetal morbidity and mortality.

To explore effectiveness of non-pharmacological interventions in fear of childbirth.

All published literature were searched from three databases (Pubmed, Cochrane CENTRAL, and Web of Science) as of April 2024. The risk of bias of the included studies was assessed using the Cochrane Systematic Review Manual 2.0 bias risk assessment tool. The primary outcome was FOC, the secondary outcomes were depression, anxiety, stress, childbirth self-efficacy, and mode of delivery.

This study included 32 randomized controlled trials, involving 17 interventions and 3,187 pregnant women. Compared with usual care, cognitive-behavioral therapy (SMD = -1.62, 95%CI -2.47 to -0.66), haptonomy (SMD = -1.43, 95%CI -2.63 to -0.24), motivational interview (SMD = -1.35, 95%CI -2.35 to -0.35), counseling therapy (SMD = -1.08, 95%CI -1.91 to -0.25) statistically and significantly improved fear of childbirth in gestational period. Emotional freedom technique (SMD = -3.13, 95%CI -5.00 to -1.26), counseling therapy (SMD = -1.81, 95%CI -2.97 to -0.80), haptonomy (SMD = -1.78, 95%CI -2.89 to -0.66), cognitive-behavioral therapy (SMD = -1.42, 95%CI -2.53 to -0.32), motivational interview (SMD = -1.28, 95%CI -2.37 to -0.19) statistically and significantly improved fear of childbirth in postnatal period. The cluster analysis showed that emotional freedom technique, haptonomy, motivational interview, cognitive-behavioral therapy, counseling therapy were considered to be more effective non-pharmacological interventions.

Several non-pharmacological interventions are promising in the daily care of pregnant women with fear of childbirth. Healthcare professionals should be encouraged to apply these non-pharmacological interventions for informal caregivers of pregnant women with fear of childbirth.

The error-related negativity (ERN) has been called a putative neural marker of anxiety risk in children, with smaller ERN amplitudes denoting greater risk in early childhood. Children of anxious mothers are at elevated risk for anxiety problems compared to children of non-anxious mothers. Still unknown is whether discrete maternal symptoms interact with child ERN to predict different forms of child anxiety risk, knowledge of which could increase our understanding of the specificity of known conditions and pathways for transgenerational effects. Targeting two of the most prevalent forms of anxiety problems across children and adults, we tested whether maternal generalized anxiety disorder (GAD) and social phobia (SP) symptoms when children were 3 years old interacted with child ERN at age 4 years to predict child symptoms of overanxiousness and separation anxiety at age 5 years. We found that greater maternal SP, but not GAD, symptoms along with smaller (i.e., less negative) child ERN predicted more separation anxiety and overanxious symptoms in children, suggesting some specificity in prediction but less specificity in outcomes regarding the transmission of anxiety risk from mothers to offspring.

Maternal trauma influences infant and adult health outcomes and may impact future generations through epigenetic modifications such as DNA methylation (DNAm). Research in humans on the intergenerational epigenetic transmission of trauma effects is limited. In this study, we assessed DNAm signatures of war-related violence by comparing germline, prenatal, and direct exposures to violence across three generations of Syrian refugees. We compared families in which a pregnant grandmother versus a pregnant mother was exposed to violence and included a control group with no exposure to war. We collected buccal swab samples and survey data from mothers and 1-2 children in each of 48 families (n = 131 participants). Based on an epigenome-wide association study (EWAS), we identified differentially methylated regions (DMPs): 14 were associated with germline and 21 with direct exposure to violence. Most DMPs showed the same directionality in DNAm change across germline, prenatal, and direct exposures, suggesting a common epigenetic response to violence. Additionally, we identified epigenetic age acceleration in association with prenatal exposure to violence in children, highlighting the critical period of in utero development. This is the first report of an intergenerational epigenetic signature of violence, which has important implications for understanding the inheritance of trauma.

Antisocial Personality Disorder (ASPD) is a complex and often debilitating condition that can emerge from early behavioral disturbances in childhood and adolescence. This narrative review provides a comprehensive overview of the current understanding of ASPD in pediatric and adolescent populations, examining key diagnostic challenges, developmental trajectories, and emerging treatment approaches. Recent research underscores the critical role of the early identification of conduct disorder (CD) and oppositional defiant disorder (ODD) as precursors to ASPD. Specific attention is given to biological, environmental, and psychosocial risk factors, including genetic predispositions, family dynamics, and socio-economic adversity. Additionally, neuro-psychological research highlights deficits in executive function, emotion regulation, and social cognition, which may underline the persistent antisocial patterns. Neuroimaging studies suggest atypical neural activity in regions associated with empathy, reward processing, and impulse control. Effective intervention remains a challenge, as treatment options are limited and often complicated by co-occurring conditions, such as attention deficit hyperactivity disorder (ADHD) and mood disorders. Promising evidence supports the efficacy of integrative, multimodal approaches combining behavioral therapy, family interventions, and pharmacotherapy to reduce symptom severity and improve long-term outcomes. The review concludes by advocating for a public health approach that emphasizes prevention and early intervention, aiming to mitigate the progression to full ASPD in adulthood.

Childhood sleep quality is associated with physical, cognitive, and behavioral health and predicts later sleep quality; it has many determinants, including developmental exposures.

To examine associations between maternal stress during pregnancy and childhood sleep quality and determine whether postnatal stress mediates the association.

Data from the Environmental Influences on Child Health Outcomes cohort were used. Perceived Stress Scale (PSS) T-scores were the exposure measure. Outcome measures were preschool Child Behavior Checklist (CBCL) sleep syndrome scale and Patient-Reported Outcomes Measurement Information System Sleep Disturbance Parent Proxy short form 4a (PSD4a) T-scores at ages 4-8 years. Linear mixed-effects regression modeling was performed for each sleep outcome, adjusting for maternal age at delivery and education and child sex, gestational age at birth, and age at outcome ascertainment, with random intercepts for cohorts.

Prenatal PSS score was associated with both CBCL (B = 0.09, 95% confidence interval [CI]: 0.06, 0.11; p < 0.01) and PSD4a (B = 0.07, 95% CI: 0.03, 0.12; p < 0.01) scores. Postnatal perceived stress mediated a proportion of the total effect of prenatal stress in both CBCL (66.3%) and PSD4a (95.9%) samples.

Both pre- and postnatal maternal perceived stress appear to influence sleep quality during early life.

Prenatal stress significantly associates with child sleep problems and disturbances at ages 4-8 years; postnatal maternal stress is a significant mediator of these associations. Research suggests a range of prenatal affective/distress exposures associated with child sleep problems, but the conclusions remain in doubt due to the mixture of exposures and outcomes employed. Ours is the first US-based effort to explore associations between perceived maternal stress during pregnancy and child sleep problems and disturbance in early and middle childhood. Even a small effect of a prevalent issue like psychosocial stress may have important public health implications at the population level.

Interpersonal violence against women is a major global health problem that may have intergenerational effects. This study investigated associations between maternal experiences of interpersonal violence and other traumatic events and maternal and infant salivary diurnal cortisol in a cohort of adolescent mothers in São Paulo, Brazil.

Adolescent mothers (14-19 years) participating in a home-visiting intervention were interviewed retrospectively about lifetime and pregnancy violence and trauma exposure. Mothers collected saliva at waking and before bedtime from themselves (n = 23) and their infants (n = 32) at 12 months postpartum. Multivariable regression models were used to examine associations between trauma history variables and salivary diurnal cortisol.

Adjusting for the intervention group, infant sex, maternal age, non-supplement medication use, and sample collection time, we found that higher-than-average lifetime trauma exposure was associated with maternal evening cortisol (b = 0.472, p-value = 0.028). Lifetime assaultive violence exposure was also associated with maternal evening cortisol (b = 0.196, p-value = 0.02). Maternal exposure to traumatic events in pregnancy was positively associated with bedtime cortisol levels of infants (b = 0.21, p = 0.01). Trauma variables were not associated with maternal or infant morning cortisol levels.

Results suggest that maternal trauma history influences both maternal and infant postnatal cortisol regulation as indexed by evening cortisol levels. These results are consistent with models of fetal programming; however, future studies should investigate potential postnatal psychobiological pathways. Lifetime trauma exposure may also become embedded in the maternal hypothalamic-adrenal-pituitary axis regulation. Future studies are needed to consider other biological pathways in the intergenerational transmission of trauma.

Opioid use among pregnant women has more than quadrupled over the past 20 years; however, comorbid risk factors such as emotion dysregulation confound the developmental consequences of prenatal opioid use. Maternal respiratory sinus arrhythmia (RSA) may help to disentangle the comorbid risk factors of prenatal emotion dysregulation and substance use and isolate their consequences on newborn neurobehavior.

We examined maternal RSA in response to a mild, infant-related stress task in pregnant people (N = 192; 30 on medications for opioid use disorder) recruited from hospitals and a specialty prenatal clinic for substance use disorder.

Three latent profiles emerged based on maternal RSA reactivity. Mothers with RSA increasing (Profile 3; more nervous system dysregulation) had higher levels of emotion dysregulation than mothers with RSA decreasing (Profile 1; well-regulated nervous system responses) but were not more likely to use opioids. Additionally, RSA profiles were associated with newborn neurobehavior, including attention, regulation, handling, and arousal.

Given the variability in opioid use across RSA profiles and profile associations with newborn neurodevelopment, future studies should examine protective factors in pregnant individuals using opioids who show more flexible RSA responses.

Our study examined maternal psychophysiology and newborn outcomes in a unique population with high levels of emotion dysregulation and opioid use. Three profiles of maternal respiratory sinus arrythmia (RSA) reactivity were identified during pregnancy: decreasing, blunted, and increasing. The RSA increasing and blunted profiles were associated with higher emotion dysregulation than the decreasing profile. Most pregnant people on medications for opioid use disorder (65%) were grouped into the blunted profile, suggesting they might be more at risk for dysregulated RSA reactivity. Differences in RSA profiles were associated with newborn outcomes, with increasing and blunted RSA predicting more newborn neurobehavioral dysregulation.

Maternal psychological distress is related to poorer physical and mental health as well as child developmental problems. Interventions that optimise maternal mental health and wellbeing during the "first 1,000 days" of life should have wide-reaching benefits for the mother and her child. Digital mental health interventions (DMHIs) during this critical period have the potential to equip women with enhanced coping strategies that can be applied and maintained in daily life. This study aimed to understand uptake of DMHIs in pregnancy, and the extent participants apply intervention strategies 10-12 months post-participation in a pilot randomised controlled trial (RCT) comparing different digital programs.

A mixed methods triangulation approach was undertaken. We explored demographic data and psychological distress measures in the intervention groups and a comparison group that were offered the intervention but did not participate or did not meet the inclusion criteria based on gestational age (n = 525). Intervention participants (n = 54) were invited to undertake an interview up to 12 months post-intervention to understand ongoing skills application. Fifteen interviews were undertaken using a phenomenological approach to analyse the data.

Baseline psychological distress results showed a significant difference between those who enrolled in the intervention, compared to those who did not, with higher psychological distress (combined), and stress and depression (sub-scale) scores for the intervention groups. Qualitative content analysis identified four main themes relating to long-term engagement: (1) Motivations to use skills; (2) Taking time for oneself; (3) Emotional support; and (4) Improving wellbeing (such as aids sleep and emotional impacts). Within each theme there were several sub-themes, including enablers or barriers to engagement.

This study indicated that women who chose to enrol in DMHIs in pregnancy have greater psychological distress than those who chose not to participate. Many participants in this study continued to apply learnt skills in everyday life, such as breathing exercises. This implies that digital strategies may be effective and applicable longer-term to enable women to apply positive coping skills during critical child developmental periods. Ultimately, this will contribute to designing apps that sustain wellbeing and could be protective in preventing postnatal psychological distress.

Psychosocial stress affects the relationship between prolactin (PRL) and cortisol (CORT). The dynamics of PRL and CORT changes under stress in human milk (HM) are largely unknown. We investigated how maternal stress related to recent life changes affects milk CORT and PRL concentrations. The study involved 116 mothers exclusively breastfeeding 5-month-old infants. Maternal psychological stress was evaluated using the Recent Life Changes Questionnaire (RLCQ). Stress response was determined by administering the cold pressor test and measuring CORT in saliva taken during and in milk collected after the test. Hormones concentrations were assayed using the ELISA method. The hierarchical regression models were run to test the association between maternal RLCQ, salivary CORT, and PRL, and CORT in milk. Maternal RLCQ correlated positively with the CORT in saliva, however, no direct association was found between RLCQ and PRL. After controlling for covariates, a positive association was found between salivary and milk CORT. A negative relationship was observed between salivary CORT and milk PRL. The results of the present study indicate that maternal psychological stress may affect the relationship between CORT and PRL in HM. In response to psychological stress, both hormones transported via milk can program infant development in the early postnatal period.

Studies suggest that greater exposure to natural vegetation (i.e., greenness) is associated with better mental health. However, there is limited research on greenness and mental health in the preconception period, a critical window of exposure in the life course. We investigated the associations of residential greenness with perceived stress and depressive symptoms using cross-sectional data from a cohort of pregnancy planners.

From 2013 to 2019, we enrolled female-identified participants aged 21-45 years who were trying to conceive without the use of fertility treatment into a North American preconception cohort study (Pregnancy Study Online [PRESTO]). On the baseline questionnaire, participants completed the 10-item Perceived Stress Scale (PSS) and the Major Depression Inventory (MDI). Using geocoded addresses, we estimated residential greenness exposure via satellite imagery (Normalized Difference Vegetation Index [NDVI]) in a 100m buffer. We estimated mean differences and 95% confidence intervals for the association of greenness with perceived stress and depression scores using linear regression models, adjusting for individual and neighborhood sociodemographic characteristics. We also evaluated the extent to which associations were modified by urbanicity and neighborhood socioeconomic status (SES).

Among 9718 participants, mean age was 29.9 years, 81.5% identified as non-Hispanic White, 25% had household incomes <$50,000, and mean neighborhood income was $61,932. In adjusted models, higher greenness was associated with lower stress and depression scores (mean difference per interquartile range in greenness: -0.20, 95% CI: -0.39, -0.01; and -0.19, 95% CI: -0.48, 0.10, respectively). The association was stronger among residents of lower SES neighborhoods in urban areas (PSS: -0.57, 95% CI: -1.00, -0.15; MDI: -0.72, 95% CI: -1.40, -0.04).

Higher greenness exposure was associated with lower stress and depressive symptoms among pregnancy planners, particularly in lower-SES neighborhoods.

Maternal stress and depression during pregnancy and the first year of the infant's life affect a large percentage of mothers. Maternal stress and depression have been associated with adverse fetal and childhood outcomes as well as differential child DNA methylation (DNAm). However, the biological mechanisms connecting maternal stress and depression to poor health outcomes in children are still largely unknown. Here we aim to determine whether prenatal stress and depression are associated with differences in cord blood mononuclear cell DNAm (CBMC-DNAm) in newborns (n = 119) and whether postnatal stress and depression are associated with differences in peripheral blood mononuclear cell DNAm (PBMC-DNAm) in children of 12 months of age (n = 113) from the Canadian Healthy Infant Longitudinal Development (CHILD) cohort. Stress was measured using the 10-item Perceived Stress Scale (PSS) and depression was measured using the 20-item Center for Epidemiologic Studies Depression Questionnaire (CESD). Both stress and depression were measured longitudinally at 18 weeks and 36 weeks of pregnancy and six months and 12 months postpartum. We conducted epigenome-wide association studies (EWAS) using robust linear regression followed by a sensitivity analysis in which we bias-adjusted for inflation and unmeasured confounding using the bacon and cate methods. To quantify the cumulative effect of maternal stress and depression, we created composite prenatal and postnatal adversity scores. We identified a significant association between prenatal stress and differential CBMC-DNAm at 8 CpG sites and between prenatal depression and differential CBMC-DNAm at 2 CpG sites. Additionally, we identified a significant association between postnatal stress and differential PBMC-DNAm at 8 CpG sites and between postnatal depression and differential PBMC-DNAm at 11 CpG sites. Using our composite scores, we further identified 2 CpG sites significantly associated with prenatal adversity and 7 CpG sites significantly associated with postnatal adversity. Several of the associated genes, including PLAGL1, HYMAI, BRD2, and ERC2 have been implicated in adverse fetal outcomes and neuropsychiatric disorders. These data further support the finding that differential DNAm may play a role in the relationship between maternal mental health and child health.

Attention deficit hyperactivity disorder (ADHD), prevalent in 5% of children worldwide, impacts academic performance and often coexists with psychiatric disorders. Psychostimulant medications are primary treatments for ADHD, enhancing dopamine to reduce symptoms. However, dopamine increase may cause appetite loss. This pioneering study in the United Arab Emirates (UAE) explores psychostimulant effects on weight in children diagnosed with ADHD, aiming to uncover unique regional characteristics and contributing factors to weight changes.

This retrospective cohort study assessed data from electronic medical records from 2017 to 2022, aiming to assess the impact of psychostimulants on weight in children aged 6-18 years. Inclusion criteria covered psychostimulant-treated and untreated patients with ADHD. Statistical analysis, involving longitudinal data methods aimed to demonstrate significant weight differences.

Data from 107 pediatric patients diagnosed with ADHD were analyzed, with 86 meeting inclusion criteria. Most patients were male (80.2%). ADHD presentations varied, and methylphenidate immediate release was the most prescribed stimulant medication. Patients experienced initial weight loss followed by overall gain over 12 months. Coexisting conditions, maternal factors, family history, and correlations with autism spectrum disorder were explored.

This study provides valuable insights into the effects of psychostimulant medications on the weight of children and adolescents diagnosed with ADHD in the UAE. It suggests avenues for future research, emphasizing extended follow-ups to understand long-term psychostimulant effects, nuanced examinations of age and gender, and exploring interactions with comorbidities. Despite limitations, the research provides insights into ADHD medication effects, guiding personalized treatment approaches for pediatric populations.

Prenatal maternal stress is linked to offspring outcomes; however, there is little research on adolescents, behavioral, transdiagnostic outcomes, or the mechanisms through which relations operate. We examined, in N = 268 adolescents (Mage = 15.31 years; SD = 1.063; 57.8% boys) whether prenatal maternal stress is associated with adolescent affective outcomes; whether this association is mediated, serially, by childhood home atmosphere and adolescent behavioral inhibition system (BIS) sensitivity; and whether mediational effects are moderated by adolescent attention-deficit/hyperactivity disorder or maternal internalizing symptomology. Prenatal maternal daily stress and major life events were associated with adolescent outcomes through childhood negative atmosphere/neglect and BIS sensitivity, with no evidence of moderation. Results have implications regarding the effect of prenatal maternal stress on offspring outcomes and regarding corresponding sensitive periods.

The literature shows that maternal stress can influence behavior and immune function in F1. Yet, most studies on these are from the laboratory, and replicated studies on the mechanisms by which maternal stress drives individual characteristics are still not fully understood in wild animals. We manipulated high- and low-density parental population density using large-scale field enclosures and examined behavior and immune traits. Within the field enclosures, we assessed anti-keyhole limpet hemocyanin immunoglobulin G (anti-KLH IgG) level, phytohemagglutinin (PHA) responses, hematology, cytokines, the depressive and anxiety-like behaviors and prevalence and intensity of coccidial infection. We then collected brain tissue from juvenile voles born at high or low density, quantified mRNA and protein expression of corticotropin-releasing hormone (CRH) and glucocorticoid receptor gene (NR3C1) and measured DNA methylation at CpG sites in a region that was highly conserved with the prairie vole CRH and NR3C1 promoter. At high density, we found that the F1 had a lower DNA methylation level of CRH and a higher DNA methylation level of NR3C1, which resulted in an increase in the expression levels of the CRH mRNA and protein expression and further reduced the expression levels of the NR3C1 mRNA and protein expression, and ultimately led to have delayed responses to acute immobilization stress. Juvenile voles born at high density also reduced anti-KLH IgG levels and PHA responses, increased cytokines, and depressive and anxiety-like behaviors, and the effects further led to higher coccidial infection. From the perspective of population density inducing the changes in behavior and immunity at the brain level, our results showed a physiological epigenetic mechanism for population self-regulation in voles. Our results indicate that altering the prenatal intrinsic stress environment can fundamentally impact behavior and immunity by DNA methylation of HPA-axis genes and can further drive population fluctuations in wild animals.

Insecure and disorganized attachment patterns in children are linked to poor health outcomes over the lifespan. Attachment patterns may be predicted by variables that influence the quality of children's interactions with their primary caregivers/parents (usually mothers) such as prenatal and postnatal exposures and the children's own behaviours in interactions. The purposes of this exploratory study were to examine: (1) prenatal predictors of children's attachment patterns, and (2) postnatal mediators and moderators of associations between prenatal predictors and children's attachment patterns, with adjustment for relevant covariates. Mother-child dyads (n = 214) from the longitudinal Alberta Pregnancy Outcomes and Nutrition (APrON) cohort were studied using valid and reliable measures. Hayes' mediation analysis was employed to determine direct and indirect effects. Mothers' prenatal cortisol levels directly predicted disorganized (versus organized) child attachment in unadjusted models. Children's passivity (in adjusted models) and compulsivity (in unadjusted and adjusted models) in parent-child interactions mediated the pathway between mothers' prenatal cortisol levels and children's disorganized attachment patterns. Serial mediation analyses revealed that mothers' cortisol levels predicted their children's cortisol levels, which predicted children's compulsivity, and, ultimately, disorganized attachment in both unadjusted and adjusted models. No predictors were correlated with children's insecure (versus secure) attachment. This exploratory research suggests that prenatal exposure to mothers' cortisol levels and children's behavioural contributions to parent-child interaction quality should be considered in the genesis of children's attachment patterns, especially disorganization. Interventions focused on parent-child interactions could also focus on addressing children's behavioral contributions.

We investigated the association between persistence and change in behavioral difficulties during early to middle childhood and several cognitive outcomes. We observed 3904 8-year-olds enrolled in the longitudinal study Growing Up in New Zealand (50% male/female; 23% Māori, 9% Pacific Peoples, 13% Asian, 2% Middle Eastern/Latin American/African, 9% Other, 43% European). The NIH Toolbox Cognition Battery was used to assess cognitive functioning at 8 years and the Strengths and Difficulties Questionnaire for behavioral difficulties at 4.5 and 8 years. Multivariate logistic regression analyses were conducted, controlling for well-known sociodemographic confounders. Children with persistent or later onset of behavioral difficulties were at higher risk for poorer vocabulary, reading, inhibitory control/attention, episodic memory, working memory and processing speed at age 8 compared to children with no or improved difficulties. Our study supports the importance of addressing both cognitive and behavioral aspects when planning educational programmes and interventions in early and middle childhood.

We investigated whether structured maternal lifestyle interventions based on Mediterranean diet or stress reduction influence fetal-infant neurodevelopment detected by detailed fetal neurosonography and Ages and Stages Questionnaires 3rd edition (ASQ) at 12 months old.

This was a secondary analysis of a randomized clinical trial (2017-2020), including 1,221 singleton pregnancies at high risk for small-for-gestational age. Participants were randomized into three groups at 19-23 weeks' gestation: Mediterranean diet intervention, stress reduction program, or usual care. A detailed neurosonography was performed on 881 participants at mean (SD) 33.4 (1.1) weeks' gestation. Neurosonographic measurements were done offline. ASQ was performed on 276 infants at 1 year of corrected age.

Biparietal diameter was similar among study groups. Mediterranean diet group fetuses had deeper insula (26.80 [1.68] versus 26.63 [1.75], mm, p = 0.02) and longer corpus callosum (42.98 [2.44] versus 42.62 [2.27], mm, p = 0.04), with a lower rate of suboptimal score infants in ASQ problem-solving domain (6.2 vs. 16.3%, p = 0.03). Stress reduction group fetuses had deeper insula (26.90 [1.75] versus 26.63 [1.75], mm, p = 0.04) and lower rates of suboptimal score infants in ASQ fine motor domain (4.3 vs. 12.8%, p = 0.04), compared to usual care group fetuses.

Maternal structured intervention during pregnancy of the trial has the potential to modify offspring's neurodevelopment.

To assess the prevalence of anxiety and depression and their associated risk factors throughout the pregnancy and postpartum process using a new screening for the early detection of mental health problems.

A prospective cross-sectional descriptive multicentred study. Participants were consecutively enrolled at ≥ 12 weeks' gestation and followed at three different time points: at 12-14 weeks of pregnancy, at 29-30 weeks of pregnancy, and 4-6 weeks postpartum. All women completed a mental screening at week 12-14 of pregnancy consisting of two questions from the Generalised Anxiety Disorder Scale (GAD-2) and the two Whooley questions. If this screening was positive, the woman completed the Edinburgh Postnatal Depression Scale (EPDS).

Seven primary care centres coordinated by a Gynaecology and Obstetrics Department in the city of Terrassa (Barcelona) in northern Spain.

Pregnant women (N = 335, age 18-45 years), in their first trimester of pregnancy, and receiving prenatal care in the public health system between July 2018 and July 2020.

The most relevant factors associated with positive screening for antenatal depression or anxiety during pregnancy, that appear after the first trimester of pregnancy, are systematically repeated throughout the pregnancy, and are maintained in the postpartum period were: a history of previous depression, previous anxiety, abuse, and marital problems. In weeks 12-14 early risk factors for positive depression and anxiety screening and positive EPDS were: age, smoking, educational level, employment status, previous psychological/psychiatric history and treatment, suicide in the family environment, voluntary termination of pregnancy and current planned pregnancy, living with a partner and partner's income. In weeks 29-30 risk factors were: being a skilled worker, a history of previous depression or anxiety, and marital problems. In weeks 4-6 postpartum, risk factors were: age, a history of previous depression or anxiety or psychological/psychiatric treatment, type of treatment, having been mistreated, and marital problems.

Early screening for anxiety and depression in pregnancy may enable the creation of more effective healthcare pathways, by acting long before mental health problems in pregnant women worsen or by preventing their onset. Assessment of anxiety and depression symptoms before and after childbirth and emotional support needs to be incorporated into routine practice.

In-utero exposure to maternal psychological distress is increasingly linked with disrupted fetal and neonatal brain development and long-term neurobehavioral dysfunction in children and adults. Elevated maternal psychological distress is associated with changes in fetal brain structure and function, including reduced hippocampal and cerebellar volumes, increased cerebral cortical gyrification and sulcal depth, decreased brain metabolites (e.g., choline and creatine levels), and disrupted functional connectivity. After birth, reduced cerebral and cerebellar gray matter volumes, increased cerebral cortical gyrification, altered amygdala and hippocampal volumes, and disturbed brain microstructure and functional connectivity have been reported in the offspring months or even years after exposure to maternal distress during pregnancy. Additionally, adverse child neurodevelopment outcomes such as cognitive, language, learning, memory, social-emotional problems, and neuropsychiatric dysfunction are being increasingly reported after prenatal exposure to maternal distress. The mechanisms by which prenatal maternal psychological distress influences early brain development include but are not limited to impaired placental function, disrupted fetal epigenetic regulation, altered microbiome and inflammation, dysregulated hypothalamic pituitary adrenal axis, altered distribution of the fetal cardiac output to the brain, and disrupted maternal sleep and appetite. This review will appraise the available literature on the brain structural and functional outcomes and neurodevelopmental outcomes in the offspring of pregnant women experiencing elevated psychological distress. In addition, it will also provide an overview of the mechanistic underpinnings of brain development changes in stress response and discuss current treatments for elevated maternal psychological distress, including pharmacotherapy (e.g., selective serotonin reuptake inhibitors) and non-pharmacotherapy (e.g., cognitive-behavior therapy). Finally, it will end with a consideration of future directions in the field.

The objective of this scoping review is to review the research evidence regarding the impact of perinatal maternal stress on the maternal and infant gut and human milk microbiomes.

Perinatal stress which refers to psychological stress experienced by individuals during pregnancy and the postpartum period is emerging as a public health concern. Early exposure of infants to perinatal maternal stress can potentially lead to metabolic, immune, and neurobehavioral disorders that extend into adulthood. The role of the gut and human milk microbiome in the microbiome-gut-brain axis as a mechanism of stress transfer has been previously reported. A transfer of colonised aberrant microbiota from mother to infant is proposed to predispose the infant to a pro- inflammatory microbiome with dysregulated metabolic process thereby initiating early risk of chronic diseases. The interplay of perinatal maternal stress and its relationship to the maternal and infant gut and human milk microbiome requires further systematic examination in the literature.

This scoping review is an exploratory mapping review which will focus on the population of mothers and infants with the exploration of the key concepts of maternal stress and its impact on the maternal and infant gut and human milk microbiome in the context of the perinatal period. It will focus on the pregnancy and the post-natal period up to 6 months with infants who are exclusively breastfed.

This study will be guided by the Joanna Briggs Institute's (JBI) methodology for scoping reviews along with use of the Prisma Scr reporting guideline. A comprehensive search will be conducted using the following databases, CINAHL Complete; MEDLINE; PsycINFO, Web of Science and Scopus. A search strategy with pre-defined inclusion and exclusion criteria will be used to retrieve peer reviewed data published in English from 2014 to present. Screening will involve a three-step process with screening tool checklists. Results will be presented in tabular and narrative summaries, covering thematic concepts and their relationships. This protocol is registered with Open Science Framework DOI 10.17605/OSF.IO/5SRMV.

To investigate the associations between maternal mental health disorders before and during pregnancy and perinatal outcomes and child healthcare utilization between 6 and 18 months of age. Among the 6814 mother-child pairs from the Italian Internet-based NINFEA birth cohort, maternal depression, anxiety, and sleep disorders diagnosed by a physician before and during pregnancy were assessed through self-reported questionnaires completed during pregnancy and 6 months after delivery. Perinatal outcomes (preterm birth, birth weight, small for gestational age, congenital anomalies, and neonatal intensive care unit (NICU)) and children's healthcare utilization (emergency department (ED) visits, hospitalizations, and outpatient visits) were reported by mothers at 6 and 18 months postpartum. We used regression models adjusted for maternal age, education, parity, country of birth, region of delivery, and household income. Maternal mental health disorders were not associated with perinatal outcomes, except for depression, which increased the risk of offspring admission to NICU, and anxiety disorders during pregnancy, which were associated with preterm birth and lower birth weight. Children born to mothers with depression/anxiety disorders before pregnancy, compared to children of mothers without these disorders, had an increased odds of a visit to ED for any reason (odds ratio (ORadj) = 1.26, 95% confidence interval (CI): 1.02-1.54), of an ED visit resulting in hospitalization (ORadj = 1.75, 95%CI: 1.27-2.42), and of planned hospital admissions (ORadj = 1.55, 95%CI: 1.01-2.40). These associations with healthcare utilization were similar for mental disorders also during pregnancy. The association pattern of maternal sleep disorders with perinatal outcomes and child healthcare utilization resembled that of maternal depression and/or anxiety disorders with these outcomes.   Conclusion: Antenatal maternal mental health is a potential risk factor for child-health outcomes and healthcare use. Early maternal mental health interventions may help to promote child health and reduce healthcare costs. What is Known: • Poor maternal mental health affects pregnancy outcomes and child health, and children of mothers with mental health conditions tend to have increased healtcare utilization. • Parents with poor mental health often face challenges in caring for their children and have less parenting self-efficacy, which could potentially lead to frequent medical consultations for minor health issues. What is New: • Maternal pre-pregnancy mental disorders were not associated with preterm birth, low birth weight, SGA, and congenital anomalies, except for depression, which increased the risk of offspring admission to NICU. Anxiety disorders during pregnancy were associated with lower birth weight and an increased odds of preterm birth. • Maternal depression and/or anxiety and sleep disorders, both before and during pregnancy, were associated with an increase in children's healthcare utilization between 6 and 18 months of life.

There are few support interventions for women with fear of childbirth tailored towards type of fears and parity. To inform the future development of an acceptable and relevant intervention for women with severe fear of childbirth, primary objectives were to examine: (1) pregnant women's experiences of and preferences for support and (2) barriers and facilitators to help-seeking. Secondary objectives were to examine if there are any differences based on pregnant women's parity.

Pregnant women with a severe fear of childbirth in Sweden completed an online cross-sectional survey between February and September 2022. Severe fear of childbirth was measured using the fear of childbirth scale. Quantitative data were analysed using descriptive and inferential statistics and free answers were analysed using manifest content analysis. A contiguous approach to integration was adopted with qualitative and quantitative findings reported separately.

In total, 609 participants, 364 nulliparous and 245 parous women, had severe fear of childbirth. The main category "A twisting road to walk towards receiving support for fear of childbirth" was explored and described by the generic categories: Longing for support, Struggling to ask for support, and Facilitating aspects of seeking support. Over half (63.5%), of pregnant women without planned or ongoing treatment, wanted support for fear of childbirth. Most (60.2%) pregnant women with ongoing or completed fear of childbirth treatment regarded the treatment as less helpful or not at all helpful. If fear of childbirth treatment was not planned, 35.8% of women would have liked to have received treatment. Barriers to help seeking included stigma surrounding fear of childbirth, previous negative experiences with healthcare contacts, fear of not being believed, fear of not being listened to, and discomfort of having to face their fears. Facilitators to help seeking included receiving respectful professional support that was easily available, flexible, and close to home.

Most pregnant women with severe fear of childbirth felt unsupported during pregnancy. Findings emphasise the need to develop individual and easily accessible psychological support for women with severe fear of childbirth, delivered by trained professionals with an empathetic and respectful attitude.

Perinatal mental health research provides an important perspective on neurobehavioral development. Here, we aim to review the association of maternal perinatal health with offspring neurodevelopment, providing an update on (self-)regulation problems, hypothesized mechanistic pathways, progress and challenges, and implications for mental health.

(1) Meta-analyses confirm that maternal perinatal mental distress is associated with (self-)regulation problems which constitute cognitive, behavioral, and affective social-emotional problems, while exposure to positive parental mental health has a positive impact. However, effect sizes are small. (2) Hypothesized mechanistic pathways underlying this association are complex. Interactive and compensatory mechanisms across developmental time are neglected topics. (3) Progress has been made in multiexposure studies. However, challenges remain and these are shared by clinical, translational and public health sciences. (4) From a mental healthcare perspective, a multidisciplinary and system level approach employing developmentally-sensitive measures and timely treatment of (self-)regulation and coregulation problems in a dyadic caregiver-child and family level approach seems needed. The existing evidence-base is sparse.

During the perinatal period, addressing vulnerable contexts and building resilient systems may promote neurobehavioral development. A pluralistic approach to research, taking a multidisciplinary approach to theoretical models and empirical investigation needs to be fostered.

Prenatal maternal distress can negatively affect pregnancy outcomes, yet its impact on the offspring's brain structure and function remains unclear. This systematic review summarizes the available literature on the relationship between prenatal maternal distress and brain development in fetuses and infants up to 12 months of age.

We searched Central, Embase, MEDLINE, PsycINFO, and PSYNDEXplus for studies published between database inception and December 2023. Studies were included if prenatal maternal anxiety, stress, and/or depression was assessed, neuroimaging was used to examine the offspring, and the offspring's brain was imaged within the first year of life. The quality of the included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies-II.

Out of the 1516 studies retrieved, 71 met our inclusion criteria. Although the studies varied greatly in their methodology, the results generally pointed to structural and functional aberrations in the limbic system, prefrontal cortex, and insula in fetuses and infants prenatally exposed to maternal distress.

The hippocampus, amygdala, and prefrontal cortex have a high density of glucocorticoid receptors, which play a key role in adapting to stressors and maintaining stress-related homeostasis. We thus conclude that in utero exposure to maternal distress prompts these brain regions to adapt by undergoing structural and functional changes, with the consequence that these alterations increase the risk for developing a neuropsychiatric illness later on. Future research should investigate the effect of providing psychological support for pregnant women on the offspring's early brain development.

Prenatal maternal stress and mental health problems are known to increase risk for developmental psychopathology in offspring, yet pathways leading to risk or resiliency are poorly understood. In a quasi-experimental design, we prospectively examined associations between disaster-related prenatal stress, maternal mental health symptoms, and infant temperament outcomes. Mothers who were pregnant during Hurricane Harvey (N = 527) reported on objective hardships (e.g., loss of belongings or income, evacuation, home flooding) related to the storm and subsequent mental health symptoms (anxiety/depression, posttraumatic stress) across time. At a postpartum assessment, mothers reported on their infant's temperament (negative affect, positive affect, orienting/regulatory capacity). Greater objective hardship indirectly predicted higher levels of infant orienting/regulatory capacity through its association with increased maternal posttraumatic stress symptoms. Greater objective hardship also indirectly predicted higher levels of infant negative affect through its association with increased maternal anxiety/depression symptoms across time. Our findings suggest a psychological mechanism linking prenatal stress with specific temperamental characteristics via maternal mental health symptoms. Findings point to the importance of high-quality assessment and mental health services for vulnerable women and young children.

Antenatal depression and maternal nutrition can influence infant temperament. Although broad-spectrum-micronutrients (BSM: vitamins and minerals) given above Recommended Dietary Allowances during pregnancy can mitigate symptoms of antenatal depression, their associated effects on infant temperament are unknown. One hundred and fourteen New Zealand mother-infant dyads (45 infants exposed to BSM during pregnancy (range of exposure during pregnancy: 12-182 days) to treat antenatal depressive symptoms (measured by Edinburgh Postnatal Depression Scale) and 69 non-exposed infants) were followed antenatally and for 12 months postpartum to determine the influence of in utero BSM exposure on infant temperament. The Infant Behavior Questionnaire-Revised: Very Short-Form assessed temperament at 4 (T1), 6 (T2) and 12 (T3) months postpartum via online questionnaire. Latent growth curve modeling showed BSM exposure, antenatal depression and infant sex did not statistically significantly predict initial levels or longitudinal changes in orienting/regulatory capacity (ORC), positive affectivity/surgency (PAS) or negative affectivity (NEG). Higher gestational age was positively associated with initial PAS, and smaller increases between T1 and T3. Breastfeeding occurrence was positively associated with initial NEG. Although not significant, BSM exposure exerted small, positive effects on initial NEG (β = -0.116) and longitudinal changes in ORC (β = 0.266) and NEG (β = -0.235). While BSM exposure did not significantly predict infant temperament, it may mitigate risks associated with antenatal depression. BSM-exposed infants displayed temperamental characteristics on par with typical pregnancies, supporting the safety of BSM treatment for antenatal depression.

Trends and gaps in perinatal anxiety research remain unknown. The objective of this bibliometric review was to analyze the characteristics and trends in published research on perinatal anxiety to inform future research.

All published literature in Web of Science on perinatal anxiety from January 1, 1920 to December 31, 2020 were screened by two reviewers. VOSViewer was utilized to visualize linkages between publications. Bibliometric data were extracted from abstracts.

The search strategy identified 4561 publications. After screening, 2203 publications related to perinatal anxiety were used for the visualization analysis. For the bibliometric data, 1534 publications had perinatal anxiety as a primary focus. There were 7910 different authors, over half named only once (55.5 %), from 63 countries. 495 journals were identified, with over half (56.0 %) publishing only one article. Most articles were published between 2011 and 2020 (75.9 %). In terms of perinatal timing, over half (54.2 %) published on antenatal anxiety. Only 6.0 % of studies reported on perinatal anxiety in fathers and 56.5 % also reported on perinatal depression.

Web of Science was solely used, and manual screening of each publication was required.

This bibliometric analysis found: (1) perinatal anxiety is a growing field of research, with publications increasing over time; (2) there is variation in authors and journals; (3) over half of the publications focus on antenatal anxiety; (4) paternal anxiety is understudied; and (5) only 6 % of publications came from low and lower-middle income countries. Gaps related to maternal postnatal anxiety and paternal perinatal anxiety exist.

There are no published studies on pregnancy-related concerns, worries, and fears (CWFs) in primiparous and multiparous women and men in U.S. Air Force (USAF) families. Reflecting a biopsychosocial model of behavioral health, women's and men's pregnancy-related CWF Questionnaires were developed. Usable data were obtained from 260 women and 243 men in USAF families. Similarities and differences in pregnancy-related CWFs were found when USAF and general population data were compared. The present findings can inform not only the general provision of pregnancy health-related services but also USAF secondary prevention pregnancy-related programs (e.g., USAF nurse home visiting programs for first-time parents). If CWF Questionnaires are individually administered, the information can be used to tailor services to individual client needs.

Objectives We aim to estimate the prevalence of anxiety among pregnant women, explore the possible risk factors, and compare the presence of anxiety in each gestational trimester in all pregnant women attending the antenatal care clinics at a tertiary care hospital in Manama, Bahrain. Methods This study followed a cross-sectional research design at the antenatal clinics of Salmaniya Medical Complex in Manama, Bahrain. Direct interviews with 513 participants were conducted using the Pregnancy Anxiety Questionnaire-Revised-2 (PRAQ-R2). Results Most participants (63%) were 25-35 years old. The majority (85.6%) were Bahraini nationals, and 52.2% were university-educated. Almost two-thirds were unemployed, 28.1% had associated chronic comorbidities, 3.1% had associated psychiatric disorders, 15% had a high level of anxiety, and 38% had a moderate level of anxiety. Employed participants had a significantly higher level of anxiety (p=0.022) than housewives/unemployed participants. Participants' levels of anxiety differed significantly according to their gestational age (p=0.043), with the highest anxiety among those in their third trimester (15.7%). Participants' anxiety levels were significantly higher among those with previously complicated pregnancies (p=0.002). Moreover, those with unplanned current pregnancy had significantly higher anxiety levels (p=0.019). Conclusions This study showed that anxiety seems to be a common disorder among pregnant women in Bahrain. It was more prevalent during the third trimester, and its occurrence was associated with the pregnant woman's employment, the occurrence of previously complicated pregnancies, and unplanned current pregnancies.

Suicide is a global issue. It is the third responsible for death among the reproductive age group. Pregnancy is a complicated event and crucial in the life of a woman with considerable physiological, hormonal changes, social, and mental changes. However, third-world countries like Ethiopia have not been investigated well. Therefore, the study planned to assess the magnitude and factors associated with suicidal ideation. Furthermore, it will identify the role of hyperemesis gravidarum on suicidal ideation.

A Cross-sectional study was employed for 543 pregnant participants attending antenatal care at Hiwot Fana Specialized University Hospital and Jugal General Hospital, Harari regional state, eastern Ethiopia from June 1 to August 1, 2022. The recruited participants were selected by systematic random sampling method. Suicide was assessed using Composite International Diagnostic by interview methods data collection. Epi data and STATA version 14.1 were used for data entry and analysis respectively. Candidate variables were entered into a multivariate logistic regression then those variables that have p-value < 0.05 were considered as significantly associated.

The magnitude of suicidal ideation in this study was found to be 11.15% at (95% CI: 8.75-14.11). Regarding the associated factor, unwanted pregnancy (AOR = 3.39: at 95% CI = 1.58-7.27), Hyperemesis gravidarum (AOR = 3.65: at 95% CI = 1.81-7.34), having depressive symptoms (AOR = 2.79: at 95% CI = 1.49-5.23), having anxiety symptoms (AOR = 3.37; at 95% CI = 1.69-6.68), experiencing intimate partner violence (AOR = 2.88: at 95% CI = 1.11-7.46), and having stress (AOR = 3.46; at 95% CI = 1.75-6.86) were significantly associated variable with suicidal ideation among pregnant women.

This study revealed that suicidal ideation is common among pregnant women. Regarding the associated factors unwanted pregnancy, hyperemesis gravidarum, having depressive and anxiety symptoms, experiencing intimate partner violence, and stress were significantly associated with suicidal ideation. Thus, giving awareness and early screening and interferences for antenatal suicide should be warranted.

Imprinted genes are expressed from one parental allele as a consequence of epigenetic processes initiated in the germline. Consequently, their ability to influence phenotype depends on their parent-of-origin. Recent research suggests that the sex of the individual expressing the imprinted gene is also important. We have previously reported that genetically wildtype (WT) dams carrying and caring for pups mutant for PEG3 exhibit anxiety-like behaviours and their mutant pups show a reduction in ultrasonic vocalisation when separated from their mothers. Sex-specificity was not examined.

WT female mice were mated with WT, heterozygous Peg3-/+ or homozygous Peg3-/- studs to generate all WT (control), 50:50 mixed or 100% mutant litters, respectively, followed by behavioural assessment of both dams and their pups.

We reproduced our original finding that WT dams carrying and caring for 100% mutant litters exhibit postpartum anxiety-like symptoms and delayed pup retrieval. Additionally, these WT dams were found to allocate less time to pup-directed care behaviours relative to controls. Male Peg3-deficient pups demonstrated significantly reduced vocalisation with a more subtle communication deficit in females. Postweaning, male mutants exhibited deficits across a number of key social behaviours as did WT males sharing their environment with mutants. Only modest variations in social behaviour were detected in experimental females.

We have experimentally demonstrated that Peg3 deficiency confined to the offspring causes anxiety in mouse mothers and atypical behaviour including deficits in communication in their male offspring. A male-specific reduction in expression PEG3 in the fetally-derived placenta has previously been associated with maternal depression in human pregnancy. Maternal mood disorders such as depression and anxiety are associated with delays in language development and neuroatypical behaviour more common in sons. Peg3 deficiency could drive the association of maternal and offspring behavioural disorders reported in humans.
