Abstract
The long-lasting effects of fetal exposure to early life influences (ELI) such as maternal anxiety, stress, and micronutrient deficiencies as well as mediating and moderating factors are quite well established in animal studies, but remain unclear in humans. Here, we report about effects on cognition, behavior, and emotion in offspring aged 5-20 years old in two prospective longitudinal birth cohorts.

Abstract
In a prospective longitudinal study, we investigated the outcomes of children born to mothers clinically referred for mental health problems during pregnancy (risk group, n = 17) relative to a control group (n = 31). Child cognitive functioning, and for subgroups (n = 10 + 17), brain morphometry as derived from Magnetic resonance imaging (MRI), was measured at 4½ years. Cognitive data included abstract visuospatial reasoning/problem solving and verbal scores. Subcortical regions of interest included the amygdala, accumbens area, hippocampus, caudate and putamen, chosen because their development seems potentially sensitive to an adverse intrauterine milieu and environmental experiences, and also due to their implication in cognitive and emotional processes. The risk group exhibited poorer abstract reasoning scores than the control group. No differences were found for verbal scores. MRI revealed smaller putamen volume in children in the risk group. Irrespective of group, putamen volume was positively related to visuospatial reasoning performance. Our results suggest that maternal psychopathology may be associated with child putamen development, nonverbal reasoning and problem solving skills.

Abstract
Exposure to high levels of early life stress has been identified as a potent risk factor for neurodevelopmental delays in infants, behavioral problems and autism in children, but also for several psychiatric illnesses in adulthood, such as depression, anxiety, autism, and posttraumatic stress disorder. Despite having robust adverse effects on both mother and infant, the pathophysiology of peripartum depression and anxiety are poorly understood. The objective of this review is to highlight the advantages of using an integrated approach addressing several behavioral domains in both animal and clinical studies of peripartum depression and anxiety. It is postulated that a greater focus on integrated cross domain studies will lead to advances in treatments and preventative measures for several disorders associated with peripartum depression and anxiety.

Abstract
OBJECTIVE To depict the processes through which animals and human beings engage their environment in continuously evolving states of conflict and cooperation. METHOD Descriptive literature review. RESULTS Life history outcomes are more relative than they are absolute. Genetic variations play a crucial role, but heavily influencing behavioral outcomes, psychopathology included, are external cues that epigenetically remodel DNA along experience-dependent signaling pathways. The result is phenotypes that either optimize adjustment, or constrain it. DISCUSSION Knowledge of epigenetic mechanisms may help shed new light on the origin of maturational phenotypes underlying eating disorders and why adjusting treatments to these realities warrants our attention.

Abstract
AIM The association between socio-economic status (SES) and cerebral palsy (CP) remains controversial. Preterm birth, low birthweight, and postnatal injuries are accepted mediating risk factors for CP, but the question remains whether SES confers additional risk. The aim of this study was to analyse existing knowledge on the relationship between SES and the risk of CP. METHOD We conducted a systematic search and review of potentially relevant research relating to SES and CP published from 1980 to 2012. Heterogeneity between studies did not allow for data aggregation or meta-analysis; therefore, a narrative review was used to summarize the findings. RESULTS Twelve studies were included in the systematic review. Of these, eight found low SES to be a risk factor for increased CP prevalence. Three studies detected statistically significant associations even after controlling for birthweight and gestational age as variables. Two of these studies also accounted for additional confounding variables (multiple births and timing of CP acquisition) and continued to detect contributory effects of SES. Linear negative correlations between CP prevalence and SES were shown by three studies. INTERPRETATION Evidence suggests that the effect of SES on CP prevalence goes beyond that of the mediating factors preterm birth, low birthweight, and postnatal trauma. These associations were seen in area-based and, to a lesser extent, individual measures of SES. A better understanding of mediating factors is imperative in developing targeted public health intervention programmes to reduce the prevalence of CP.

Abstract
Research implicates prenatal maternal stress (PNMS) as a risk factor for neurodevelopmental disorders; however few studies report PNMS effects on autism risk in offspring. We examined, prospectively, the degree to which objective and subjective elements of PNMS explained variance in autism-like traits among offspring, and tested moderating effects of sex and PNMS timing in utero. Subjects were 89 (46F/43M) children who were in utero during the 1998 Quebec Ice Storm. Soon after the storm, mothers completed questionnaires on objective exposure and subjective distress, and completed the Autism Spectrum Screening Questionnaire (ASSQ) for their children at age 6½. ASSQ scores were higher among boys than girls. Greater objective and subjective PNMS predicted higher ASSQ independent of potential confounds. An objective-by-subjective interaction suggested that when subjective PNMS was high, objective PNMS had little effect; whereas when subjective PNMS was low, objective PNMS strongly affected ASSQ scores. A timing-by-objective stress interaction suggested objective stress significantly affected ASSQ in first-trimester exposed children, though less so with later exposure. The final regression explained 43% of variance in ASSQ scores; the main effect of sex and the sex-by-PNMS interactions were not significant. Findings may help elucidate neurodevelopmental origins of non-clinical autism-like traits from a dimensional perspective.

Abstract
Many prospective studies have shown that if a mother is depressed, anxious or stressed while pregnant, this increases the risk for her child having a wide range of adverse outcomes including emotional problems, symptoms of attention deficit hyperactivity disorder (ADHD) or impaired cognitive development. Although genetics and postnatal care clearly affect these outcomes, evidence for a prenatal causal component also is substantial. Prenatal anxiety/depression may contribute 10-15 % of the attributable load for emotional/behavioural outcomes.The mechanisms underlying these changes are just starting to be explored. One possible mediating factor is increased exposure of the fetus to cortisol, as has been shown in animal studies. However, the human hypothalamic-pituitary-adrenal (HPA) axis which makes cortisol functions differently in human pregnancy from in most animals. The maternal HPA axis becomes gradually less responsive to stress as pregnancy progresses. And there is only a weak, if any, association between a mother's prenatal mood and her cortisol level, especially later in pregnancy. Cytokines are alternative possible mediators. An additional explanation is that stress or anxiety causes increased transfer of maternal cortisol across the placenta to the fetus. The placenta plays a crucial role in moderating fetal exposure to maternal factors and presumably in preparing the fetus for the environment in which it is going to find itself. There is some evidence in both rat models and in humans that prenatal stress can reduce placental 11β-HSD2, the enzyme which metabolises cortisol to inactive cortisone. The level of cortisol in the amniotic fluid, surrounding the baby in the womb, has been shown to be inversely correlated with infant cognitive development. However, several other biological systems are likely to be involved. Serotonin is another possible mediator of prenatal stress induced programming effects on offspring neurocognitive and behavioural development. The role of epigenetic changes in mediating alterations in offspring outcome following prenatal stress is likely to be important and starting to be explored.

Abstract
Accumulating evidence from preclinical and clinical studies indicates that maternal psychosocial stress and anxiety during pregnancy adversely affect child outcomes. However, knowledge on the possible mechanisms underlying these relations is limited. In the present paper, we review the most often proposed mechanism, namely that involving the HPA axis and cortisol, as well as other less well-studied but possibly relevant and complementary mechanisms. We present evidence for a role of the following mechanisms: compromised placental functioning, including the 11β-HSD2 enzyme, increased catecholamines, compromised maternal immune system and intestinal microbiota, and altered health behaviors including eating, sleep, and exercise. The roles of (epi)genetics, the postnatal environment and the fetus are also discussed. We conclude that maternal prenatal psychosocial stress is a complex phenomenon that affects maternal emotions, behavior and physiology in many ways, and may influence the physiology and functioning of the fetus through a network of different pathways. The review concludes with recommendations for future research that helps our understanding of the mechanisms by which maternal prenatal stress exerts its effect on the fetus.

Abstract
The prevalence of preterm birth (PTB) is high worldwide, especially in developing countries like Brazil. PTB is marked by a stressful environment in intra- as well as extrauterine life, which can affect neurodevelopment and hormonal and physiological systems and lead to long-term negative outcomes. Nevertheless, little is known about PTB and related outcomes later on in childhood. Thus, the goals of the current study were threefold: (1) comparing cortisol and alpha-amylase (sAA) profiles, including cortisol awakening response (CAR), between preterm and full-term children; (2) evaluating whether preterm children are more responsive to acute stress and (3) assessing their memory skills and emotional and behavioral profiles. Basal cortisol and sAA profiles, including CAR of 30 preterm children, aged 6 to 10 years, were evaluated. Further, we assessed memory functions using the Wide Range Assessment of Memory and Learning, and we screened behavior/emotion using the Strengths and Difficulties Questionnaire. The results of preterm children were compared to an age- and sex-matched control group. One week later, participants were exposed to a standardized laboratory stressor [Trier Social Stress Test for Children (TSST-C)], in which cortisol and sAA were measured at baseline, 1, 10 and 25 min after stressor exposure. Preterm children had higher cortisol concentrations at awakening, a flattened CAR and an exaggerated response to TSST-C compared to full-term children. These alterations were more pronounced in girls. In addition, preterm children were characterized by more emotional problems and poorer memory performance. Our findings illustrate the long-lasting and in part sex-dependent effects of PTB on the hypothalamic-pituitary-adrenal (HPA) axis, internalizing behavior and memory. The findings are in line with the idea that early adversity alters the set-point of the HPA axis, thereby creating a more vulnerable phenotype.

Abstract
Fetal development is a critical period for shaping the lifelong health of an individual. However, the fetus is susceptible to internal and external stimuli that can lead to adverse long-term health consequences. Glucocorticoids are an important developmental switch, driving changes in gene regulation that are necessary for normal growth and maturation. The fetal hypothalamic-pituitary-adrenal (HPA) axis is particularly susceptible to long-term programming by glucocorticoids; these effects can persist throughout the life of an organism. Dysfunction of the HPA axis as a result of fetal programming has been associated with impaired brain growth, altered behaviour and increased susceptibility to chronic disease (such as metabolic and cardiovascular disease). Moreover, the effects of glucocorticoid-mediated programming are evident in subsequent generations, and transmission of these changes can occur through both maternal and paternal lineages.

Abstract
There is a growing body of evidence suggesting that events during prenatal life can have long-lasting effects on development and adult health. Stress during pregnancy is common and has been linked to increased incidence of a range of affective and behavioral outcomes in the offspring in later life and also some somatic outcomes. Glucocorticoids, and their actions on the fetus, which are regulated by placental 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2), are hypothesized to mediate these effects. Animal studies have demonstrated long-term effects of stress and glucocorticoid administration on behavioral outcomes, as well as increased blood pressure, altered hypothalamic pituitary adrenal axis (HPA) function, and decreased glucose tolerance and brain size. In humans, licorice, which inhibits placental 11β-HSD2 when consumed during pregnancy, has been shown to increase the risk of behavioral problems linked to altered HPA activity. Synthetic glucocorticoids administered during pregnancy to improve fetal lung maturity in threatened preterm birth have been shown to reduce birth weight and head circumference, but have not been linked to gross changes in long-term health to date. It is important to consider the long-term consequences of stress, and medication that mimics stress, during pregnancy.

Abstract
Maternal anxiety during pregnancy has been consistently shown to negatively affect offspring neurodevelopmental outcomes. However, little is known about the impact of positive maternal traits/states during pregnancy on the offspring. The present study was aimed at investigating the effects of the mother's mindfulness and anxiety during pregnancy on the infant's neurocognitive functioning at 9 months of age. Mothers reported mindfulness using the Freiburg Mindfulness Inventory and anxiety using the Symptom Checklist (SCL-90) at ± 20.7 weeks of gestation. Event-related brain potentials (ERPs) were measured from 79 infants in an auditory oddball paradigm designed to measure auditory attention-a key aspect of early neurocognitive functioning. For the ERP responses elicited by standard sounds, higher maternal mindfulness was associated with lower N250 amplitudes (P < 0.01, η(2) = 0.097), whereas higher maternal anxiety was associated with higher N250 amplitudes (P < 0.05, η(2) = 0.057). Maternal mindfulness was also positively associated with the P150 amplitudes (P < 0.01, η(2) = 0.130). These results suggest that infants prenatally exposed to higher levels of maternal mindfulness devote fewer attentional resources to frequently occurring irrelevant sounds. The results show that positive traits and experiences of the mother during pregnancy may also affect the unborn child. Emphasizing the beneficial effects of a positive psychological state during pregnancy may promote healthy behavior in pregnant women.

Abstract
OBJECTIVES Maternal prenatal stress is associated with elevated risk of adverse behavioural outcomes in offspring. This association may involve developmental disruption to limbic-prefrontal white matter circuitry, of which the uncinate fasciculus is the major tract. One potential candidate for modulating brain development is maternal prenatal stress. We provide the first prospective study of prenatal stress and white matter microstructure in children. METHODS A total of 22 healthy children (mean age 7 years) of mothers recruited in pregnancy underwent diffusion tensor magnetic resonance imaging. We examined correlations between prenatal stressful life events and white matter microstructural organisation indices (fractional anisotropy (FA) and perpendicular diffusivity (Dperp)) of the uncinate fasciculus and a "control" tract. RESULTS Maternal prenatal stressful life events were correlated positively with right uncinate fasciculus FA, and negatively with right uncinate fasciculus Dperp in their child, with a similar trend with left uncinate fasciculus Dperp. Prenatal stress was not associated with control tract properties; sociodemographic/obstetric variables were not associated with FA/Dperp of either tract. CONCLUSIONS Variation in maternal prenatal stress may be associated with differences in the development of white matter within brain networks underlying child social behaviour.

Abstract
Pregnancy anxiety is a potent predictor of adverse birth and infant outcomes. The goal of the current study was to examine one potential mechanism whereby these effects may occur by testing associations between pregnancy anxiety and maternal salivary cortisol on 4 occasions during pregnancy in a sample of 448 women. Higher mean levels of pregnancy anxiety over the course of pregnancy predicted steeper increases in cortisol trajectories compared to lower pregnancy anxiety. Significant differences between cortisol trajectories emerged between 30 and 31 weeks of gestation. Results remained significant when adjusted for state anxiety and perceived stress. Neither changes in pregnancy anxiety over gestation, nor pregnancy anxiety specific to only a particular time in pregnancy predicted cortisol. These findings provide support for one way in which pregnancy anxiety may influence maternal physiology and contribute to a growing literature on the complex biological pathways linking pregnancy anxiety to birth and infant outcomes.

Abstract
OBJECTIVES As there are currently no specific measures of anxiety due to prenatal diagnostic procedures, the aim of the study was to develop and validate a new measure called the Prenatal Diagnostic Procedure Anxiety Scale (PDPAS). METHODS Seventy-four pregnant women scheduled for amniocentesis and ultrasound completed the PDPAS, the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, and the Perceived Stress Scale before undergoing the diagnostic procedure. Reliability, concurrent validity, factor structure, scale sensitivity, and specificity were analyzed. Differences between amniocentesis and ultrasound groups in the PDPAS score were analyzed with a t-test. RESULTS The final scale comprised 11 items and two subscales measuring 'fear of procedure' and 'fear of abnormal result'. Concurrent validity analysis showed that the PDPAS is an independent measure of anxiety. At a cut-off score of >11, sensitivity was 75.0% and specificity was 72.01% with moderate accuracy. Fear of procedure was higher in the amniocentesis group, whereas fear of abnormal result was equally present in both amniocentesis and ultrasound groups. CONCLUSION The PDPAS has good internal consistency and concurrent validity with satisfactory psychometric characteristics. As a short measure of situation-specific anxiety, it can be used as a screening tool in prenatal clinical settings.

Study protocol for a randomized, controlled, superiority trial comparing the clinical and cost- effectiveness of integrated online mental health assessment-referral-care in pregnancy to usual prenatal care on prenatal and postnatal mental health and infant health and development: the Integrated Maternal Psychosocial Assessment to Care Trial (IMPACT). Trials 2014; 15:72. [PMID: 24597683 PMCID: PMC4015853 DOI: 10.1186/1745-6215-15-72] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2013] [Accepted: 02/13/2014] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Stress, depression, and anxiety affect 15 to 25% of pregnant women. However, fewer than 20% of prenatal care providers assess and treat mental health problems and fewer than 20% of pregnant women seek mental healthcare. For those who seek treatment, the lack of health system integration and existing barriers frequently prevent treatment access. Without treatment, poor prenatal mental health can persist for years and impact future maternal, child, and family well-being. METHODS/DESIGN The purpose of this randomized controlled trial is to evaluate the effectiveness of an integrated process of online psychosocial assessment, referral, and cognitive behavior therapy (CBT) for pregnant women compared to usual prenatal care (no formal screening or specialized care). The primary outcome is self-reported prenatal depression, anxiety, and stress symptoms at 6 to 8 weeks postrandomization. Secondary outcomes are postpartum depression, anxiety, and stress symptoms; self-efficacy; mastery; self-esteem; sleep; relationship quality; coping; resilience; Apgar score; gestational age; birth weight; maternal-infant attachment; infant behavior and development; parenting stress/competence; and intervention cost-effectiveness, efficiency, feasibility, and acceptability. Pregnant women are eligible if they: 1) are <28 weeks gestation; 2) speak/read English; 3) are willing to complete email questionnaires; 4) have no, low, or moderate psychosocial risk on screening at recruitment; and 5) are eligible for CBT. A sample of 816 women will be recruited from large, urban primary care clinics and allocation is by computer-generated randomization. Women in the intervention group will complete an online psychosocial assessment, and those with mild or moderate depression, anxiety, or stress symptoms then complete six interactive cognitive behavior therapy modules. All women will complete email questionnaires at 6 to 8 weeks postrandomization and at 3, 6, and 12 months postpartum. Clinic-based providers and researchers conducting chart abstraction and analysis are blinded. Qualitative interviews with 8 to 10 healthcare providers and 15 to 30 intervention group women will provide data on feasibility and acceptability of the intervention. Results of this trial will determine the feasibility and effectiveness of an integrated approach to prenatal mental healthcare and the use of highly accessible computer-based psychosocial assessment and CBT on maternal, infant, and family-based outcomes.

Abstract
AIM The aim of this study was to assess the cognitive and behavioural development of children with healthy birth outcomes whose mothers were exposed to prenatal stress but did not experience pregnancy complications. METHOD In this prospective study, self-reported data, including the Prenatal Life Events Checklist about stressful life events (SLEs) during different stages of pregnancy, were collected at 32 to 34 weeks' gestation. Thirty-eight healthy females (mean age 27 y 8 mo, SD 2 y 4 mo) who were exposed to severe SLEs in the first trimester were defined as the exposed infant group, and 114 matched comparison participants were defined as the unexposed infant group (1:3). Maternal postnatal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale. The Bayley Scales of Infant Development and the Toddler Temperament Scale were used to evaluate the cognitive development and temperament characteristics of the infants with healthy birth outcomes when they were 16 to 18 months old. RESULTS A randomized block multivariate analysis of covariance showed that the mental development index scores of the infants of mothers with prenatal exposure to SLEs in the first trimester averaged seven points (95% confidence interval 3.23-10.73 points) lower than those of the unexposed infants. Moreover, the infants in the exposed group achieved higher scores for regularity (adjusted mean [SD] 2.77 [0.65] vs. 2.52 [0.78], F(5,146) =5.27, p=0.023) and for persistence and attention span (adjusted mean 3.61 [0.72] vs. 3.35 [0.52], F(5,146) =5.51, p=0.020). INTERPRETATION This study provides evidence that lower cognitive ability and less optimal worse behavioural response in infants might independently result from prenatal maternal stress.

Abstract
Foetal growth restriction (FGR), reflective of an adverse intrauterine environment, confers a significantly increased risk of perinatal mortality and morbidity. In addition, low birthweight associates with adult diseases including hypertension, metabolic dysfunction and behavioural disorders. A key mechanism underlying FGR is exposure of the foetus to glucocorticoids which, while critical for foetal development, in excess can reduce foetal growth and permanently alter organ structure and function, predisposing to disease in later life. Foetal glucocorticoid exposure is regulated, at least in part, by the enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which catalyses the intracellular inactivation of glucocorticoids. This enzyme is highly expressed within the placenta at the maternal-foetal interface, limiting the passage of glucocorticoids to the foetus. Expression of 11β-HSD2 is also high in foetal tissues, particularly within the developing central nervous system. Down-regulation or genetic deficiency of placental 11β-HSD2 is associated with significant reductions in foetal growth and birth weight, and programmed outcomes in adulthood. To unravel the direct significance of 11β-HSD2 for developmental programming, placental function, neurodevelopment and adult behaviour have been extensively investigated in a mouse knockout of 11β-HSD2. This review highlights the evidence obtained from this mouse model for a critical role of feto-placental 11β-HSD2 in determining the adverse programming outcomes.

Abstract
OBJECTIVE To examine the risk of psychosis associated with severe bereavement stress during the antenatal and postnatal period, between conception to adolescence, and with different causes of death. DESIGN Population based cohort study. SETTING Swedish national registers including births between 1973 and 1985 and followed-up to 2006. PARTICIPANTS In a cohort of 1,045,336 Swedish births (1973-85), offspring born to mothers exposed to severe maternal bereavement stress six months before conception or during pregnancy, or exposed to loss of a close family member subsequently from birth to 13 years of age were followed until 2006. Admissions were identified by linkage to national patient registers. MAIN OUTCOME MEASURES Crude and adjusted odds ratios for all psychosis, non-affective psychosis, and affective psychosis. RESULTS Maternal bereavement stress occurring preconception or during the prenatal period was not associated with a significant excess risk of psychosis in offspring (adjusted odds ratio, preconception 1.24, 95% confidence interval 0.96 to 1.62; first trimester 0.95, 0.58 to 1.56; second trimester 0.79, 0.46 to 1.33; third trimester 1.14, 0.78 to 1.66). Risks increased modestly after exposure to the loss of a close family member from birth to adolescence for all psychoses (adjusted odds ratio 1.17, 1.04 to 1.32). The pattern of risk was generally similar for non-affective and affective psychosis. Thus estimates were higher after death in the nuclear compared with extended family but remained non-significant for prenatal exposure; the earlier the exposure to death in the nuclear family occurred in childhood (all psychoses: adjusted odds ratio, birth to 2.9 years 1.84, 1.41 to 2.41; 3-6.9 years 1.47, 1.16 to 1.85; 7-12.9 years 1.32, 1.10 to 1.58) and after suicide. Following suicide, risks were especially higher for affective psychosis (birth to 2.9 years 3.33, 2.00 to 5.56; 6.9 years 1.84, 1.04 to 3.25; 7-12.9 years 2.68, 1.84 to 3.92). Adjustment for key confounders attenuated but did not explain associations with risk. CONCLUSIONS Postnatal but not prenatal bereavement stress in mothers is associated with an increased risk of psychosis in offspring. Risks are especially high for affective psychosis after suicide in the nuclear family, an effect that is not explained by family psychiatric history. Future studies are needed to understand possible sources of risk and resilience so that structures can be put in place to support vulnerable children and their families.

Abstract
BACKGROUND Preconception, prenatal and postnatal maternal stress is associated with increased offspring psychopathology, but findings are inconsistent and need replication. We estimated associations between maternal bereavement stress and offspring autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), bipolar disorder, schizophrenia, suicide attempt and completed suicide. METHOD Using Swedish registers, we conducted the largest population-based study to date examining associations between stress exposure in 738,144 offspring born 1992-2000 for childhood outcomes and 2,155,221 offspring born 1973-1997 for adult outcomes with follow-up to 2009. Maternal stress was defined as death of a first-degree relative during (a) the 6 months before conception, (b) pregnancy or (c) the first two postnatal years. Cox proportional survival analyses were used to obtain hazard ratios (HRs) in unadjusted and adjusted analyses. RESULTS Marginal increased risk of bipolar disorder and schizophrenia following preconception bereavement stress was not significant. Third-trimester prenatal stress increased the risk of ASD [adjusted HR (aHR) 1.58, 95% confidence interval (CI) 1.15-2.17] and ADHD (aHR 1.31, 95% CI 1.04-1.66). First postnatal year stress increased the risk of offspring suicide attempt (aHR 1.13, 95% CI 1.02-1.25) and completed suicide (aHR 1.51, 95% CI 1.08-2.11). Bereavement stress during the second postnatal year increased the risk of ASD (aHR 1.30, 95% CI 1.09-1.55). CONCLUSIONS Further research is needed regarding associations between preconception stress and psychopathological outcomes. Prenatal bereavement stress increases the risk of offspring ASD and ADHD. Postnatal bereavement stress moderately increases the risk of offspring suicide attempt, completed suicide and ASD. Smaller previous studies may have overestimated associations between early stress and psychopathological outcomes.

Abstract
OBJECTIVE To assess the following among women hospitalized antenatally due to high-risk pregnancies: (1) rates of depression symptoms and anxiety symptoms, (2) changes in depression symptoms and anxiety symptoms and, (3) rates of mental health treatment. METHODS Sixty-two participants hospitalized for high-risk obstetrical complications completed the Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder 7-item scale (GAD-7) and Short-Form 12 weekly until delivery or discharge, and once postpartum. RESULTS Average length of total hospital stay was 8.3 ± 7.6 days for women who completed an initial admission survey (n = 62) and 16.3 ± 8.9 (n = 34), 25.4 ± 10.2 (n = 17) and 35 ± 10.9 days (n = 9) for those who completed 2, 3 and 4 surveys, respectively. EPDS was ≥ 10 in 27% (n=17) and GAD-7 was ≥ 10 in 13% (n = 8) of participants at initial survey. Mean anxiety (4.2 ± 6.5 vs. 5.2 ± 5.1, p = .011) and depression (4.4 ± 5.6 vs. 6.9 ± 4.8, p = .011) scores were lower postpartum compared to initial survey. Past mental health diagnosis predicted depression symptoms [odds ratio (OR) = 4.54; 95% confidence interval (CI) 1.91-7.17] and anxiety symptoms (OR = 5.95; 95% CI 3.04-8.86) at initial survey; however, 21% (n = 10) with no diagnostic history had EPDS ≥ 10. Five percent (n = 3) received mental health treatment during pregnancy. CONCLUSION Hospitalized high-risk obstetrical patients may commonly experience depression symptoms and/or anxiety symptoms and not receive treatment. A history of mental health treatment or diagnosis was associated with depression symptoms or anxiety symptoms in pregnancy. Of women with an EPDS ≥ 10, > 50% did not report a past mental health diagnosis.

Abstract
Adrenal glucocorticoids (Gc) are among the most significant hormones in the mammalian organisms; these steroids may reach and penetrate all tissues where they interact with cytoplasmic/nuclear receptors, through which they exert multiple and very multifaceted actions. The effects of physiological concentrations of Gc on brain functions have not been completely clarified, even though Gc are recognized to influence behavioral responses, emotions, cognitive processes and to take part in the neuroendocrine control of body homeostasis. Developmental programming effects of Gc in animal models and humans have been proposed. Actually, pre-natal stress, or exposure to high Gc levels, would somehow affect neuronal developmental events in some structure and this can lead to central nervous system altered functions, as the impairment of neuroendocrine activities, cognitive processes, sleep and mood disorders. Interestingly, it has been observed that these abnormalities may not be limited to the first directly exposed individuals but transmissible across generations. The establishment of animal models with localized pre-natal glucocorticoid receptors deficiency led to the accumulation of data on the possible roles of these hormones on development of the central and peripheral nervous system. The most recent findings on the effects of Gc on neuroblast development, with particular attention to neuronal migration, will be presented.

Abstract
OBJECTIVE In this paper we evaluate the evidence for sex differences in fetal programming within the context of the proposed viability-vulnerability tradeoff. METHODS We briefly review the literature on the factors contributing to primary and secondary sex ratios. Sex differences in fetal programming are assessed by summarizing previously published sex difference findings from our group (6 studies) and also new analyses of previously published findings in which sex differences were not reported (6 studies). RESULTS The review and reanalysis of studies from our group are consistent with the overwhelming evidence of increasing risk for viability among males exposed to environmental adversity early in life. New evidence reported here support the argument that females, despite their adaptive agility, also are influenced by exposure to early adversity. Two primary conclusions are (i) female fetal exposure to psychobiological stress selectively influences fear/anxiety, and (ii) the effects of female fetal exposure to stress persist into preadolescence. These persisting effects are reflected in increased levels of anxiety, impaired executive function and neurological markers associated with these behaviors. CONCLUSIONS A tacit assumption is that females, with their adaptive flexibility early in gestation, escape the consequences of early life exposure to adversity. We argue that the consequences of male exposure to early adversity threaten their viability, effectively culling the weak and the frail and creating a surviving cohort of the fittest. Females adjust to early adversity with a variety of strategies, but their escape from the risk of early mortality and morbidity has a price of increased vulnerability expressed later in development.

Overexposure of the developing fetus to glucocorticoids is hypothesised to be one of the key mechanisms linking early life development with later life disease. The maternal hypothalamic-pituitary-adrenal (HPA) axis undergoes dramatic changes during pregnancy and postpartum. Although cortisol levels rise threefold by the third trimester, the fetus is partially protected from high cortisol by activity of the enzyme 11β-hydroxysteroid dehydrogenase type 2 (HSD11B2). Maternal HPA axis activity and activity of HSD11B2 may be modified by maternal stress and disease allowing greater transfer of glucocorticoids from mother to fetus. Here we review emerging data from human studies linking dysregulation of the maternal HPA axis to outcomes in both the mother and her offspring. For the offspring, greater glucocorticoid exposure is associated with lower birth weight and shorter gestation at delivery. In addition, evidence supports longer term consequences for the offspring including re-setting of the HPA axis and susceptibility to neurodevelopmental problems and cardiometabolic disease. For the mother, the changes in the HPA axis, particularly in the postpartum period, may increase vulnerability to mood disturbances. Further understanding of the changes in the HPA axis during pregnancy and the impact of these changes may ultimately allow early identification of those most at risk of future disease.

Abstract
Exposure to maternal anxiety predicts offspring brain development. However, because children's brains are commonly assessed years after birth, the timing of such maternal influences in humans is unclear. This study aimed to examine the consequences of antenatal and postnatal exposure to maternal anxiety upon early infant development of the hippocampus, a key structure for stress regulation. A total of 175 neonates underwent magnetic resonance imaging (MRI) at birth and among them 35 had repeated scans at 6 months of age. Maternal anxiety was assessed using the State-Trait Anxiety Inventory (STAI) at week 26 of pregnancy and 3 months after delivery. Regression analyses showed that antenatal maternal anxiety did not influence bilateral hippocampal volume at birth. However, children of mothers reporting increased anxiety during pregnancy showed slower growth of both the left and right hippocampus over the first 6 months of life. This effect of antenatal maternal anxiety upon right hippocampal growth became statistically stronger when controlling for postnatal maternal anxiety. Furthermore, a strong positive association between postnatal maternal anxiety and right hippocampal growth was detected, whereas a strong negative association between postnatal maternal anxiety and the left hippocampal volume at 6 months of life was found. Hence, the postnatal growth of bilateral hippocampi shows distinct responses to postnatal maternal anxiety. The size of the left hippocampus during early development is likely to reflect the influence of the exposure to perinatal maternal anxiety, whereas right hippocampal growth is constrained by antenatal maternal anxiety, but enhanced in response to increased postnatal maternal anxiety.

Abstract
The developing foetus makes adaptations to an adverse in utero environment which may lead to permanent changes in structure and physiology, thus 'programming' the foetus to risk of ill health in later life. Epidemiological studies have shown associations between low birth weight, a surrogate marker of an adverse intrauterine environment, and a range of diseases in adult life including cardiometabolic and psychiatric disease. These associations do not apply exclusively to low birth weight babies but also to newborns within the normal birth weight range. Early life stress, including stressors in the prenatal and early postnatal period, is a key factor that can have long-term effects on offspring health. Animal studies show this is mediated through changes in the maternal and foetal hypothalamic-pituitary-adrenal axes resulting in foetal exposure to excess glucocorticoids. Data in humans are more limited but support that the biological effects of stress in utero may be transmitted through changes in glucocorticoid action or metabolism. Common contemporary physical and social stressors of maternal obesity and socio-economic deprivation impact on the maternal response to pregnancy and the prevailing hormonal milieu that the developing foetus will be exposed to. Prenatal stress may also be compounded by early postnatal stresses such as childhood maltreatment with resultant adverse effects for the offspring. Understanding of the mechanisms whereby these stressors are transmitted from mother to foetus will not only improve our knowledge of normal foetal development but will also help identify novel pathways for early intervention either in the periconceptional, pregnancy or the early postpartum period.

Abstract
OBJECTIVE The objective of this study was to determine whether a web-based education strategy could improve maternal knowledge of placental complications of pregnancy and reduce maternal anxiety in high risk-pregnancies. METHODS Prospective study in the Placenta Clinic at Mount Sinai Hospital, Toronto, Ontario. Maternal demographics and Internet usage were recorded at the patient's baseline appointment. Placental knowledge was determined using structured verbal and illustrative assessments. The six-item State-Trait Anxiety Inventory (STAI) was administered to assess baseline maternal anxiety. Women were asked to visit the Placenta Clinic website for a minimum of 15 minutes before their follow-up appointment, at which time their placental knowledge and STAI assessments were repeated. RESULTS Eighteen women were included in the study. Patient knowledge at the baseline appointment was generally poor (median score 10.5 out of a maximum score of 27, range 1 to 22), with major deficits in basic placental knowledge, placenta previa/increta, and preeclampsia. At the follow-up appointment, placental knowledge was significantly improved (median score 23, range 10 to 27; P < 0.001). Educational status (high school or less vs. college or more) had no effect on either baseline knowledge or knowledge improvement. Maternal anxiety at baseline (median score 12 out of a maximum score of 24, range 6 to 23) was significantly reduced at the follow-up appointment (median score 8.5, range 6 to 20; P = 0.005). CONCLUSION Deficits in maternal knowledge of placental complications of pregnancy in high-risk pregnant women were substantial but easily rectified with a disease-targeted web-based educational resource. This intervention significantly improved patient knowledge and significantly reduced maternal anxiety.

Abstract
BACKGROUND Prenatal stress has been shown to predict persistent behavioural abnormalities in offspring. Unknown is whether prenatal stress makes children more vulnerable to peer victimisation. METHODS The current study is based on the Avon Longitudinal Study of Parents and Children, a prospective community-based study. Family adversity, maternal anxiety and depression were assessed at repeated intervals in pregnancy and the postnatal period. Parenting, partner conflict and temperament were measured at preschool age. Peer victimisation was assessed using multiple informants (child, parent, teacher) at primary school age (between ages 7 and 10). RESULTS Prenatal severe family adversity and maternal mental health directly increased the risk of victimisation at school even when controlled for postnatal family adversity and maternal mental health, parenting, partner conflict and temperament. Effects were found to be independent of sources of information of peer victimisation. Partner conflict and maladaptive parenting also independently increased the risk of peer victimisation. CONCLUSIONS Experiences in pregnancy may affect the developing foetus and increase vulnerability to be victimised by peers. Conflict between parents and their parenting further increase the risk of being victimised by peers at school.

Abstract
In a national US sample of pregnant women (n=311), we investigated the question of who becomes highly anxious about pregnancy by examining putative sociodemographic, pregnancy- and mental health-related predictors of pregnancy anxiety. We also assessed the contribution of pregnancy anxiety to the risk of significant alcohol consumption during pregnancy. English-speaking pregnant women aged 18+years were recruited online. Results indicated that sociodemographic factors (younger age, white, unmarried, lower education, lower household income, no previous children), feelings about current pregnancy (unwanted), and general anxiety (higher general and state anxiety) predicted higher pregnancy-related anxiety, whereas age, religiosity, number of weeks pregnant, unplanned pregnancy, and maternal depressive symptoms did not. Pregnancy anxiety was the single strongest predictor of alcohol drinking risk during pregnancy (p<.001, ∆R(2)=.10) a relationship that held after controlling for other significant predictors. Pregnancy anxiety also represented the strongest predictor of screening positively for drinking risk during pregnancy at the total T-ACE (an alcohol risk screener for pregnancy) level of 3+ (odds ratio 95% CI=1.61-4.14, p<.001), though not at the level of 2+ (odds ratio 95% CI=0.98-1.68, p=.07). We discuss implications for the link between maternal mental health and birth/ child outcomes.

Abstract
OBJECTIVE Data on psychiatric morbidity in high-risk pregnant Singaporean women are limited. This study aimed to establish the prevalence of antenatal depression and anxiety in high-risk pregnancies, compare the prevalence of antenatal depression in high-risk pregnancies vs. pregnancies of unspecified obstetric risk and examine the Edinburgh Postnatal Depression Scale (EPDS) and State Trait Anxiety Inventory (STAI) as screening tools for these disorders. METHOD Two hundred high-risk pregnant inpatients at a national public maternity hospital were included. Three psychometric assessment tools were used to evaluate all participants: the diagnostic Mini International Neuropsychiatric Interview and the screening EPDS and STAI. RESULTS Rates of major depression, minor depression, anxiety disorder (agoraphobia, generalized anxiety disorder, panic disorder), and comorbid depression and anxiety were 11%, 7%, 12.5% and 5%, respectively. Major depression was more prevalent in high-risk pregnancies than in the historical cohort of unspecified obstetric risk (11% versus 4.3%). EPDS (cutoff 8/9) screens well for depression and anxiety in high-risk pregnancies (area under the receiver operating characteristic curve=0.82-0.87). CONCLUSION Antenatal depression and anxiety are highly prevalent in a sample of high-risk pregnant Singaporean women. EPDS performs well in screening for depression and anxiety in high-risk pregnant women, with further psychiatric assessment recommended for women with score ≥ 9.

Abstract
The gestational state is a period of particular vulnerability to diseases that affect maternal and fetal health. Stress during gestation may represent a powerful influence on maternal mental health and offspring brain plasticity and development. Here we show that the fetal transcriptome, through microRNA (miRNA) regulation, responds to prenatal stress in association with epigenetic signatures of psychiatric and neurological diseases. Pregnant Long-Evans rats were assigned to stress from gestational days 12 to 18 while others served as handled controls. Gestational stress in the dam disrupted parturient maternal behaviour and was accompanied by characteristic brain miRNA profiles in the mother and her offspring, and altered transcriptomic brain profiles in the offspring. In the offspring brains, prenatal stress upregulated miR-103, which is involved in brain pathologies, and downregulated its potential gene target Ptplb. Prenatal stress downregulated miR-145, a marker of multiple sclerosis in humans. Prenatal stress also upregulated miR-323 and miR-98, which may alter inflammatory responses in the brain. Furthermore, prenatal stress upregulated miR-219, which targets the gene Dazap1. Both miR-219 and Dazap1 are putative markers of schizophrenia and bipolar affective disorder in humans. Offspring transcriptomic changes included genes related to development, axonal guidance and neuropathology. These findings indicate that prenatal stress modifies epigenetic signatures linked to disease during critical periods of fetal brain development. These observations provide a new mechanistic association between environmental and genetic risk factors in psychiatric and neurological disease.

Abstract
BACKGROUND Accumulating data from animal and human studies indicate that the prenatal environment plays a significant role in shaping children's neurocognitive development. Clinical, epidemiologic, and basic science research suggests that two experiences relatively common in pregnancy - an unhealthy maternal diet and psychosocial distress - significantly affect children's future neurodevelopment. These prenatal experiences exert their influence in the context of one another and yet, almost uniformly, are studied independently. SCOPE AND METHOD OF REVIEW In this review, we suggest that studying neurocognitive development in children in relation to both prenatal exposures is ecologically most relevant, and methodologically most sound. To support this approach, we selectively review two research topics that demonstrate the need for dual exposure studies, including exemplar findings on (a) the associations between pregnant women's inadequate maternal intake of key nutrients - protein, fat, iron, zinc, and choline - as well as distress in relation to overlapping effects on children's neurocognitive development; and (b) cross-talk between the biology of stress and nutrition that can amplify each experience for the mother and fetus,. We also consider obstacles to this kind of study design, such as questions of statistical methods for 'disentangling' the exposure effects, and aim to provide some answers. CONCLUSION Studies that specifically include both exposures in their design can begin to determine the relative and/or synergistic impact of these prenatal experiences on developmental trajectories - and thereby contribute most fully to the understanding of the early origins of health and disease.

Abstract
OBJECTIVE Conflicting data have led to controversy regarding antidepressant use during pregnancy. The objectives of this study are to i) review the risks of untreated depression and anxiety, ii) review the literature on risks of exposure to antidepressants during pregnancy, iii) discuss the strengths and weaknesses of the different study designs used to evaluate those risks, and iv) provide clinical recommendations. METHOD MEDLINE/PubMed was searched for reports and studies on the risk of first-trimester teratogenicity, postnatal adaptation syndrome (PNAS), and persistent pulmonary hypertension (PPHN) with in utero antidepressant exposure. RESULTS While some individual studies suggest associations between some specific major malformations, the findings are inconsistent. Therefore, the absolute risks appear small. PNAS occurs in up to 30% of neonates exposed to antidepressants. In some studies, PPHN has been weakly associated with in utero antidepressant exposure, while in other studies, there has been no association. CONCLUSION Exposures of concern include that of untreated maternal illness as well as medication exposure. It is vital to have a careful discussion, tailored to each patient, which incorporates the evidence to date and considers methodological and statistical limitations. Past medication trials, previous success with symptom remission, and women's preference should guide treatment decisions.

Abstract
According to the Barker hypothesis, the period of pregnancy and the intrauterine environment are crucial to the tendency to develop diseases like hypertension, diabetes, coronary heart disease, metabolic disorders, pulmonary, renal and mental illnesses. The external environment affects the development of a particular phenotype suitable for an environment with characteristics that closely resemble intrauterine conditions. If the extra-uterine environment differs greatly from the intra-uterine one, the fetus is more prone to develop disease. Subsequent studies have shown that maternal diseases like depression and anxiety, epilepsy, asthma, anemia and metabolic disorders, like diabetes, are able to determine alterations in growth and fetal development. Similarly, the maternal lifestyle, particularly diet, exercise and smoking during pregnancy, have an important role in determining the risk to develop diseases that manifest themselves both during childhood and particularly in adulthood. Finally, there are abundant potential sources of pollutants, both indoor and outdoor, in the environment in which the child lives, which can contribute to an increased probability to the development of several diseases and that in some cases could be easily avoided.

Abstract
Adverse environments during the fetal and neonatal development period may permanently program physiology and metabolism, and lead to increased risk of diseases in later life. Programming of the hypothalamic-pituitary-adrenal (HPA) axis is one of the key mechanisms that contribute to altered metabolism and response to stress. Programming of the HPA axis often involves epigenetic modification of the glucocorticoid receptor (GR) gene promoter, which influences tissue-specific GR expression patterns and response to stimuli. This review summarizes the current state of research on the HPA axis and programming of health and disease in the adult, focusing on the epigenetic regulation of GR gene expression patterns in response to fetal and neonatal stress. Aberrant GR gene expression patterns in the developing brain may have a significant negative impact on protection of the immature brain against hypoxic-ischemic encephalopathy in the critical period of development during and immediately after birth.

Abstract
A simple internet search of 'maternal stress and pregnancy' turns up hundreds of hits explaining that an adverse intrauterine environment can affect fetal development and potentially lead to various learning, behavioral, and mood disorders in childhood, as well as complex diseases such as obesity and cardiovascular conditions later in life. Indeed, a growing body of literature now links several intrauterine challenges, including maternal obesity and stress, with adverse developmental outcomes in the child. Over the past 5 years, nearly 5000 publications have explored the consequences of maternal distress on young offspring, a marked increase from the 475 published studies over a comparable period 20 years ago. Yet, despite this explosion of research and widespread warnings to pregnant mothers, we still lack a basic understanding of the pathophysiology linking adverse maternal health to the onset of disease in the child, especially regarding how prenatal and perinatal challenges might affect brain development. Recent studies have begun to explore the cellular basis of the abnormal brain cytoarchitecture associated with fetal exposure to intrauterine challenges. Here, our goal is to review the scientific evidence that maternal distress interferes with key neurodevelopmental steps, as an entry point toward mapping the pathophysiology of pre- and perinatal stress on the unborn child's brain.

Abstract
Anxiety disorders during pregnancy are highly prevalent and associated with serious and enduring consequences for both mother and child. Exposure-based cognitive behavioral (CBT) and behavioral therapies (BT) represent the most empirically supported psychosocial treatments for anxiety disorders in general adult samples. Pregnant women, however, generally have been excluded from this body of research. Evidence that pregnant women inhabit a unique biological context combined with untested assumptions that exposure would unduly stress or harm the fetus have likely prohibited inquiry. This paper seeks to remedy this gap by integrating findings from obstetric, psychiatric, and psychological research to inform central questions regarding exposure-based treatment of anxiety disorders during pregnancy. Based on available evidence, we consider the potential risks and benefits of CBT/BT for anxiety disorders during pregnancy relative to other currently available treatment options. From a multidisciplinary research perspective, we argue that exposure-based therapies are likely to be safe during pregnancy, particularly relative to the alternatives. However, we also highlight critical questions for future research to directly test the biopsychological impact of exposure-based therapies among pregnant women.

Abstract
Prenatal exposure to maternal stress, anxiety, and depression can have lasting effects on infant development with risk of psychopathology. Although the impact of prenatal maternal distress has been well documented, the potential mechanisms through which maternal psychosocial variables shape development have yet to be fully elucidated. Advances in molecular biology have highlighted the role of epigenetic mechanisms in regulating gene activity, neurobiology, and behavior and the potential role of environmentally induced epigenetic variation in linking early life exposures to long-term biobehavioral outcomes. In this article, we discuss evidence illustrating the association between maternal prenatal distress and both fetal and infant developmental trajectories and the potential role of epigenetic mechanisms in mediating these effects. Postnatal experiences may have a critical moderating influence on prenatal effects, and we review findings illustrating prenatal-postnatal interplay and the developmental and epigenetic consequences of postnatal mother-infant interactions. The in utero environment is regulated by placental function and there is emerging evidence that the placenta is highly susceptible to maternal distress and a target of epigenetic dysregulation. Integrating studies of prenatal exposures, placental function, and postnatal maternal care with the exploration of epigenetic mechanisms may provide novel insights into the pathophysiology induced by maternal distress.

Abstract
Epidemiological evidence suggests that exposure to an adverse environment in early life is associated with an increased risk of cardio-metabolic and behavioral disorders in adulthood, a phenomenon termed 'early life programming'. One major hypothesis for early life programming is fetal glucocorticoid overexposure. In animal studies, prenatal glucocorticoid excess as a consequence of maternal stress or through exogenous administration to the mother or fetus is associated with programming effects on cardiovascular and metabolic systems and on the brain. These effects can be transmitted to subsequent generations. Studies in humans provide some evidence that prenatal glucocorticoid exposure may exert similar programming effects on glucose/insulin homeostasis, blood pressure and neurodevelopment. The mechanisms by which glucocorticoids mediate these effects are unclear but may include a role for epigenetic modifications. This review discusses the evidence for glucocorticoid programming in animal models and in humans.

Late preterm birth: a review of medical and neuropsychological childhood outcomes. Neuropsychol Rev 2012; 22:438-50.

Abstract
Late preterm (LP) birth (34 0/7 - 36 6/7 weeks' gestation) accounts for nearly three-fourths of all preterm births, making this population a sizeable public health concern. The immature fetal development associated with LP delivery increases the risk of mortality and short-term medical complications. Which combination of maternal, fetal, or neonatal risk factors may be most critical has only recently begun to be addressed, and whether LP birth's disruptive impact on brain development will exert adverse effects on neuropsychological functioning in childhood and adolescence has been understudied. Early data have shown a graded response, with LP children often functioning better than very preterm children but worse than term children, and with subtle intellectual and neuropsychological deficits in LP children compared with healthy children born at term gestational age. Further characterization of the neuropsychological profile is required and would be best accomplished through prospective longitudinal studies. Moreover, since moderate and LP births result in disparate medical and psychological outcomes, the common methodology of combining these participants into a single research cohort to assess risk and outcome should be reconsidered. The rapidly growing LP outcomes literature reinforces a critical principle: fetal development occurs along a dynamic maturational continuum from conception to birth, with each successive gestational day likely to improve overall outcome.

Abstract
Experimental animal models have demonstrated that one of the primary consequences of prenatal stress is increased fear and anxiety in the offspring. Few prospective human studies have evaluated the consequences of prenatal stress on anxiety during preadolescence. The purpose of this investigation is to determine the consequences of prenatal exposure to both maternal biological stress signals and psychological distress on anxiety in preadolescent children. Participants included 178 mother-child pairs. Maternal psychological distress (general anxiety, perceived stress, depression and pregnancy-specific anxiety) and biological stress signals were evaluated at 19, 25, and 31 gestational weeks. Anxiety was evaluated in the children at 6-9 years of age using the Child Behavior Checklist. Analyses revealed that prenatal exposure to elevated maternal cortisol, depression, perceived stress and pregnancy-specific anxiety was associated with increased anxiety in children. These associations remained after considering obstetric, sociodemographic and postnatal maternal psychological distress; factors that could influence child development. When all of the prenatal measures were considered together, cortisol and pregnancy-specific anxiety independently predicted child anxiety. Children exposed to elevated prenatal maternal cortisol and pregnancy-specific anxiety were at an increased risk for developing anxiety problems during the preadolescent period. This project identifies prenatal risk factors associated with lasting consequences for child mental health and raises the possibility that reducing maternal distress during the prenatal period will have long term benefits for child well-being.

Abstract
Distress-linked activation of the maternal hypothalamic-pituitary-adrenal (HPA)-axis is considered a pathway by which affect regulation impacts the fetal milieu and neurodevelopment. There is little direct evidence for this conceptual model. In 103 women [mean age 27.45 (±5.65) years] at 36-38 weeks gestation, salivary cortisol was measured before/after stress tasks; distress questionnaires were completed. At 18.49 (±1.83) weeks, infants underwent the Harvard Infant Behavioral Reactivity Protocol assessing cry/motor responses to novelty; women reported on infant behavior and postnatal distress. Prenatal cortisol and distress were not significantly correlated (all ps > .10). Proportional odds logistic regressions showed that neither prenatal nor postnatal distress was associated with infant responses to the Harvard Protocol yet pre-stress cortisol and maternal age were: The odds of being classified as High Reactive were 1.60 times higher [95% CI: 1.04, 2.46] for each unit of added cortisol and .90 times lower [95% CI: .82, .99] for every additional year in maternal age. No associations were found between cortisol or prenatal distress and mother-rated infant behavior; postnatal distress was positively associated with mother-rated infant negative behavior (p = .03). Observer and mother-rated infant behavior were not associated (all ps > .05). Based on independent observations of infants in contrast to maternal perceptions, these results lend support to the hypothesis that pregnant women's HPA-axis activity influences infant behavior. The impact of maternal distress was not supported, except in so far as postnatal distress may increase the likelihood of making negative judgments about infant behavior.

Abstract
The developmental origins of disease or fetal programming model predict that early exposures to threat or adverse conditions have lifelong consequences that result in harmful outcomes for health. The maternal endocrine 'fight or flight' system is a source of programming information for the human fetus to detect threats and adjust their developmental trajectory for survival. Fetal exposures to intrauterine conditions including elevated stress hormones increase the risk for a spectrum of health outcomes depending on the timing of exposure, the timetable of organogenesis and the developmental milestones assessed. Recent prospective studies, reviewed here, have documented the neurodevelopmental consequences of fetal exposures to the trajectory of stress hormones over the course of gestation. These studies have shown that fetal exposures to biological markers of adversity have significant and largely negative consequences for fetal, infant and child emotional and cognitive regulation and reduced volume in specific brain structures.

Abstract
Considerable evidence has accumulated on the association between pregnancy-specific stress and adverse birth outcomes with an increasing number of measures of pregnancy-specific stress being developed internationally. However, the introduction of these measures has not always been theoretically or psychometrically grounded, resulting in questions about the quality and direction of such research. This review summarizes evidence on the reliability and validity of pregnancy-specific stress measures identified between 1980 and October 2010. Fifteen pregnancy-specific stress measures were identified. Cronbach's alpha coefficient ranged from 0.51-0.96 and predictive validity data on preterm birth were reported for five measures. Convergent validity data suggest that pregnancy-specific stress is related to, but distinct from, global stress. Findings from this review consolidate current knowledge on pregnancy-specific stress as a consistent predictor of premature birth. This review also advances awareness of the range of measures of pregnancy-specific stress and documents their strengths and limitations based on published reliability and validity data. Careful consideration needs to be given as to which measures to use in future research to maximize the development of stress theory in pregnancy and appropriate interventions for women who experience stress in pregnancy. An international, strategic collaboration is recommended to advance knowledge in this area of study.

Abstract
Epidemiological, clinical, physiological, cellular, and molecular evidence suggests that the origins of obesity and metabolic dysfunction can be traced back to intrauterine life and supports an important role for maternal nutrition prior to and during gestation in fetal programming. The elucidation of underlying mechanisms is an area of interest and intense investigation. In this perspectives paper we propose that in addition to maternal nutrition-related processes it may be important to concurrently consider the potential role of intrauterine stress and stress biology. We frame our arguments in the larger context of an evolutionary-developmental perspective that supports roles for both nutrition and stress as key environmental conditions driving natural selection and developmental plasticity. We suggest that intrauterine stress exposure may interact with the nutritional milieu, and that stress biology may represent an underlying mechanism mediating the effects of diverse intrauterine perturbations, including but not limited to maternal nutritional insults (undernutrition and overnutrition), on brain and peripheral targets of programming of body composition, energy balance homeostasis, and metabolic function. We discuss putative maternal-placental-fetal endocrine and immune/inflammatory candidate mechanisms that may underlie the long-term effects of intrauterine stress. We conclude with a commentary of the implications for future research and clinical practice.

Abstract
During gestation, the fetal brain develops dramatically as structures and connections form, providing the foundation for all future development. The fetal environment plays a critical role in these early neural processes, for better or for worse. Scientists now know that exposure to maternal stress can sometimes have deleterious effects on the fetus, depending on the cause, timing, duration, and intensity of stress. Fortunately, postnatal interventions, such as a secure parent-infant bond and an enriched environment, can buffer the potential negative consequences.

Abstract
PURPOSE OF REVIEW To briefly review results of the latest research on the contributions of depression, anxiety, and stress exposures in pregnancy to adverse maternal and child outcomes, and to direct attention to new findings on pregnancy anxiety, a potent maternal risk factor. RECENT FINDINGS Anxiety, depression, and stress in pregnancy are risk factors for adverse outcomes for mothers and children. Anxiety in pregnancy is associated with shorter gestation and has adverse implications for fetal neurodevelopment and child outcomes. Anxiety about a particular pregnancy is especially potent. Chronic strain, exposure to racism, and depressive symptoms in mothers during pregnancy are associated with lower birth weight infants with consequences for infant development. These distinguishable risk factors and related pathways to distinct birth outcomes merit further investigation. SUMMARY This body of evidence, and the developing consensus regarding biological and behavioral mechanisms, sets the stage for a next era of psychiatric and collaborative interdisciplinary research on pregnancy to reduce the burden of maternal stress, depression, and anxiety in the perinatal period. It is critical to identify the signs, symptoms, and diagnostic thresholds that warrant prenatal intervention and to develop efficient, effective and ecologically valid screening and intervention strategies to be used widely.

Abstract
BACKGROUND/AIMS Accumulating evidence from a relatively small number of prospective studies indicates that exposure to prenatal stress profoundly influences the developing human fetus with consequences that persist into childhood and very likely forever. METHODS Maternal/fetal dyads are assessed at ∼20, ∼25, ∼31 and ∼36 weeks of gestation. Infant assessments begin 24 h after delivery with the collection of cortisol and behavioral responses to the painful stress of the heel-stick procedure and measures of neonatal neuromuscular maturity. Infant cognitive, neuromotor development, stress and emotional regulation are evaluated at 3, 6 12 and 24 months of age. Maternal psychosocial stress and demographic information is collected in parallel with infant assessments. Child neurodevelopment is assessed with cognitive tests, measures of adjustment and brain imaging between 5 and 8 years of age. RESULTS Psychobiological markers of stress during pregnancy, especially early in gestation, result in delayed fetal maturation, disrupted emotional regulation and impaired cognitive performance during infancy and decreased brain volume in areas associated with learning and memory in 6- to 8-year-old children. We review findings from our projects that maternal endocrine alterations that accompany pregnancy and influence fetal/infant/child development are associated with decreased affective responses to stress, altered memory function and increased risk for postpartum depression. CONCLUSIONS Our findings indicate that the mother and her fetus both are influenced by exposure to psychosocial and biological stress. The findings that fetal and maternal programming occur in parallel may have important implications for long-term child development and mother/child interactions.
