Abstract
Natural disasters (NDs) experienced by women and their children during prenatal and infant growth may have long-lasting effects on offspring’s development. Handgrip strength (HGS) is one of the measures of muscular strength and an indicator of health status. This study compared HGS in children exposed to cyclone Aila in India during their prenatal and infant growth compared to a control group from a non-affected, adjacent area. The total sample involved 444 boys and 423 girls aged 7–9 years, categorised into 3 groups: prenatally exposed to Aila, exposed to Aila in infancy, and the control group, non-exposed to Aila. Results revealed that prenatally exposed children of both sexes had significantly lower HGS than the controls (at least, p < 0.001 in boys; p < 0.05 in girls). On the other hand, the postnatally exposed boys, but not the girls, showed lower HGS than the controls. A significant effect of a group factor (ND exposure) on HGS was observed even after controlling for confounding variables (age, height, BMI, birth weight, gestational age; at least, p < 0.05). Our findings indicate that prenatal or early postnatal experience of a ND may have association with impaired HGS in prepubertal children.

Abstract
BACKGROUND Stress in pregnancy predicts adverse birth outcomes. Stressors occurring prior to conception may also pose risk for the mother and child. The few published studies on preconception stress test a single stress measure and examine only linear associations with birth outcomes. PURPOSE Guided by findings in the prenatal stress literature, the current study aimed to (i) identify latent factors from a set of preconception stress measures and (ii) examine linear and curvilinear associations between these stress factors and length of gestation. METHODS Study 1 utilized a sample of 2,637 racially/ethnically diverse women to develop a measurement model of maternal stress from assessments of seven acute and chronic stress measures. Factor analysis revealed three latent factors representing stressors (life events, financial strain, interpersonal violence, discrimination), stress appraisals (perceived stress, parenting stress), and chronic relationship stress (family, partner stress). Study 2 examined the associations of these three latent preconception stress factors with the length of gestation of a subsequent pregnancy in the subset of 360 women who became pregnant within 4.5 years. RESULTS Controlling for prenatal medical risks, there was a significant linear effect of stress appraisals on the length of gestation such that more perceived stress was associated with shorter gestation. There was a curvilinear effect of stressors on the length of gestation with moderate levels associated with longer gestation. CONCLUSIONS These results have implications for research on intergenerational origins of developmental adversities and may guide preconception prevention efforts. Findings also inform approaches to the study of stress as a multidimensional construct.

Abstract
PURPOSE OF REVIEW Understanding variability in developmental outcomes following exposure to early life adversity (ELA) has been an area of increasing interest in psychiatry, as resilient outcomes are just as prevalent as negative ones. However, resilient individuals are understudied in most cohorts and even when studied, resilience is typically defined as an absence of psychopathology. This review examines current approaches to resilience and proposes more comprehensive and objective ways of defining resilience. RECENT FINDINGS Of the 36 studies reviewed, the most commonly used measure was the Strengths and Difficulties Questionnaire (n = 6), followed by the Child Behavior Checklist (n = 5), the Resilience Scale for Chinese Adolescents (n = 5), the Rosenberg Self-Esteem Scale (n = 4), and the Child and Youth Resilience Scale (n = 3). SUMMARY This review reveals that studies tend to rely on self-report methods to capture resilience which poses some challenges. We propose a complementary measure of child resilience that relies on more proactive behavioral and observational indicators; some of our preliminary findings are presented. Additionally, concerns about the way ELA is characterized as well as the influence of genetics on resilient outcomes prompts further considerations about how to proceed with resiliency research.

Abstract
Prenatal insults during fetal development result in increased likelihood of developing chronic disease. Obesity, the biggest risk factor for the development of metabolic disease, is affected by several genetic and environmental factors. High-fat diet (HFD) consumption is usually linked with the development of obesity. The main goal of this study was to analyze the impact of the exposure to a HFD in prenatally stressed animals. For this purpose, we subjected pregnant BALB/c mice to restraint stress for 2 h a day between gestational day (GD) 14 and GD 21. Prenatally stressed and control offspring of both sexes were postnatally exposed to a HFD for 24 weeks. We found that prenatal stress (PS) per se produced disturbances in males such as increased total blood cholesterol and triglycerides, with a decrease in mRNA expression of sirtuin-1. When these animals were fed a HFD, we observed a rise in glucose and insulin levels and an increase in visceral adipose tissue gene expression of leptin, resistin, and interleukin-1 beta. Although females proved to be more resilient to PS consequences, when they were fed a HFD, they showed significant metabolic impairment. In addition to the changes observed in males, females also presented an increase in body weight and adiposity and a rise in cholesterol levels.

Abstract
OBJECTIVES To investigate the association between maternal employment precarity and infant low birth weight (LBW), and to assess if this association differs by race/ethnicity. METHODS Data were collected from 2871 women enrolled in the National Longitudinal Survey of Youth 1979 and the National Longitudinal Survey of Youth 1979 Children and Young Adult Cohort. Employment precarity was evaluated using a summary variable that combined several employment attributes: availability of employer-sponsored insurance, income, long shifts, non-daytime shifts, availability of employer sponsored training or educational benefits and membership in a union or collective bargaining unit. Employment precarity scores (a sum of the number of negative employment attributes) were categorised into low (0-2), medium (3) and high (4-6). LBW was defined as weight less than 2500 g at birth. Modified Poisson models were fit to calculate risk ratios and 95% CIs and adjusted for maternal age, race/ethnicity, educational attainment, nativity, prepregnancy body mass index, alcohol consumption, smoking during pregnancy and infant year of birth. We assessed effect modification by maternal race/ethnicity using a composite exposure-race variable. RESULTS Women with high employment precarity had higher risk of a LBW delivery compared with women with low employment precarity (RR: 1.48, 95% CI: 1.11 to 1.98). Compared to non-Hispanic/non-black women with low employment precarity, non-Hispanic black women (RR: 2.68; 95% CI: 1.72 to 4.15), Hispanic women (RR: 2.53; 95% CI: 1.54 to 4.16) and non-Hispanic/non-black women (RR: 1.46; 95% CI: 0.98 to 2.16) with high employment precarity had higher risk of LBW. CONCLUSIONS We observed higher risk of LBW in pregnancies of women with high employment precarity; this association was stronger among black and Hispanic mothers compared to non-Hispanic/non-black women. Findings of this study can be used to inform antenatal care and identify workplace policies to better support women who work during pregnancy.

Abstract
Background There have been few studies to examine antenatal predictors of incident postnatal depression, particularly in low- and middle-income countries (LMICs). The aim of this study was to investigate antenatal predictors of incident and persistent maternal depression in a rural Ethiopian community in order to inform development of antenatal interventions. Method A population-based prospective study was conducted in Sodo district, south central Ethiopia. A locally validated version of the Patient Health Questionnaire (PHQ-9) was used to assess antenatal (second and third trimesters) and postnatal (4–12 weeks after childbirth) depressive symptoms, with a PHQ-9 cut-off of five or more indicating high depressive symptoms. Poisson regression with robust standard errors was used to identify independent predictors of persistence and incidence of postnatal depressive symptoms from a range of antenatal, clinical and psychosocial risk factors. Result Out of 1311 women recruited antenatally, 1240 (356 with and 884 without antenatal depressive symptoms) were followed up in the postnatal period. Among 356 women with antenatal depressive symptoms, the elevated symptoms persisted into postnatal period in 138 women (38.8%). Out of 884 women without antenatal depressive symptoms, 136 (15.4%) experienced incident elevated depressive symptoms postnatally. The prevalence of high postnatal depressive symptoms in the follow-up sample was 274 (22.1%). Higher intimate partner violence scores in pregnancy were significantly associated with greater risk of incident depressive symptoms [adjusted Risk Ratio (aRR) = 1.06, 95% CI: 1.00, 1.12]. Each 1-point increment in baseline PHQ-9 score predicted an increased risk of incidence of postnatal depressive symptoms (aRR = 1.29, 95% CI: 1.15, 1.45). There was no association between self-reported pregnancy complications, medical conditions or experience of threatening life events with either incidence or persistence of depressive symptoms. Conclusion Psychological and social interventions to address intimate partner violence during pregnancy may be the most important priorities, able to address both incident and persistent depression.

Abstract
Background Natural disasters increase the level population stress, including pregnant women, who can experience prenatal maternal stress, affecting the fetus and triggering perinatal complications, such as low birth weight, smaller head circumference, etc. However, little is known about effects of earthquake on perinatal outcomes. Objective To evaluate the effect of earthquake occurred on February 27, 2010 and perinatal outcomes of Chilean pregnant women, and to examine these effects by timing of exposure during pregnancy and newborn gender. Methods A register-based study was performed using data collected from women who had a vaginal delivery in a large private health center in Santiago, Chile, during 2009 and 2010. The study population was categorized according to exposure to earthquake and timing during gestation. Primary perinatal outcomes were gestational age at birth, birth weight, length and head circumference. Analyses adjusted for gender, gestational age at exposure, parity, maternal age and income. Results A total of 1,966 eligible vaginal deliveries occurred during 2009 and 2,110 in 2010. Birth weight was not affected by the trimester of exposure; however, length, head circumference and gestational age at birth were significantly different according to trimester of exposure and gender of newborn. In multivariable analysis, newborns were shorter by 2 mm, 5 mm and 4.5 mm, if they were exposed during their first, second and third trimester, respectively. Furthermore, newborns had a smaller head circumference by 1.2 mm and 1.5 mm if they were exposed during first and second trimester of gestation. Conclusion In this cohort, exposure to the February 2010 earthquake resulted in earlier delivery and reduced length and head circumference in the offspring. This association varied according to trimester of exposure and fetal gender. Health workers should include exposed to high levels of stress associated with natural disasters when assessing pregnancy risk factors.

DNA methylation mediates the effect of maternal cognitive appraisal of a disaster in pregnancy on the child's C-peptide secretion in adolescence: Project Ice Storm. PLoS One 2018; 13:e0192199.

Abstract
Animal and human studies suggest that prenatal exposure to stress is associated with adverse health outcomes such as type 2 diabetes. Epigenetic modification, such as DNA methylation, is considered one possible underlying mechanism. The 1998 Quebec ice storm provides a unique opportunity to study an independent prenatal stressor on child outcomes. C-peptide is the best measure of endogenous insulin secretion and is widely used in the clinical management of patients with diabetes. The objectives of this study are to determine 1) the extent to which prenatal exposure to disaster-related stress (maternal objective hardship and maternal cognitive appraisal) influences children’s C-peptide secretion, and 2) whether DNA methylation of diabetes-related genes mediates the effects of prenatal stress on C-peptide secretion. Children’s (n = 30) C-peptide secretion in response to an oral glucose tolerance test were assessed in blood at 13½ years. DNA methylation levels of selected type 1 and 2 diabetes-related genes were chosen based upon the genes associated with prenatal maternal objective hardship and/or cognitive appraisal levels. Bootstrapping analyses were performed to determine the mediation effect of DNA methylation. We found that children whose mothers experienced higher objective hardship exhibited higher C-peptide secretion. Cognitive appraisal was not directly associated with C-peptide secretion. DNA methylation of diabetes-related genes had a positive mediation effect of objective hardship on C-peptide secretion: higher objective hardship predicted higher C-peptide secretion through DNA methylation. Negative mediation effects of cognitive appraisal were observed: negative cognitive appraisal predicted higher C-peptide secretion through DNA methylation. However, only one gene, LTA, remained a significant mediator of cognitive appraisal on C-peptide secretion after the conservative Bonferroni multiple corrections. Our findings suggest that DNA methylation could act as an intervening variable between prenatal stress and metabolic outcomes, highlighting the importance of epigenetic mechanisms in response to environmental factors.

Abstract
BACKGROUND Uptake of delivery and postnatal care remains low in Low and Middle-Income Countries (LMICs), where 99% of global maternal deaths take place. However, the potential impact of antenatal depression on use of institutional delivery and postnatal care has seldom been examined. This study aimed to examine whether antenatal depressive symptoms are associated with use of maternal health care services. METHODS A population-based prospective study was conducted in Sodo District, Southern Ethiopia. Depressive symptoms were assessed during pregnancy with a locally validated, Amharic version of the Patient Health Questionnaire (PHQ-9). A cut off score of five or more indicated possible depression. A total of 1251 women were interviewed at a median of 8 weeks (4-12 weeks) after delivery. Postnatal outcome variables were: institutional delivery care utilization, type of delivery, i.e. spontaneous or assisted, and postnatal care utilization. Multivariate logistic regression was used to examine the association between antenatal depressive symptoms and the outcome variables. RESULTS High levels of antenatal depressive symptoms (PHQ score 5 or higher) were found in 28.7% of participating women. Nearly two-thirds, 783 women (62.6%), delivered in healthcare institutions. After adjusting for potential confounders, women with antenatal depressive symptoms had increased odds of reporting institutional birth [adjusted Odds Ratio (aOR) =1.42, 95% Confidence Interval (CI): 1.06, 1.92] and increased odds of reporting having had an assisted delivery (aOR = 1.72, 95% CI: 1.10, 2.69) as compared to women without these symptoms. However, the increased odds of institutional delivery among women with antenatal depressive symptoms was associated with unplanned delivery care use mainly due to emergency reasons (aOR = 1.62, 95% CI: 1.09, 2.42) rather than planning to deliver in healthcare institutions. CONCLUSION Improved detection and treatment of antenatal depression has the potential to increase planned institutional delivery and reduce perinatal complications, thus contributing to a reduction in maternal morbidity and mortality.

Abstract
The manifestation of anxiety during pregnancy can be caused by multiple factors and may have emotional and physical consequences for both the mother and the fetus. The prevalence of gestational anxiety has grown in recent years, making the development of studies for its comprehension essential. Thus, the aim of this investigation was to evaluate the effects of predictable and unpredictable chronic stressors on the anxiety profile of rats in three distinct stages of pregnancy (1st, 2nd and 3rd weeks). Wistar dams were divided into three groups: control, social separation and unpredictable chronic stress. Behavioral assessments were conducted in the Elevated Plus-Maze at the end of the 1st, 2nd and 3rd weeks of gestation. The results showed that there was increased anxiety in the proximity of parturition in control dams. Chronic stressors differentially affected the behavior of pregnant rats according to the gestational period where they were applied: social separation decreased anxiety at the end of the 3rd week, while unpredictable chronic stress caused increased anxiety, especially at the end of the 2nd gestational week. These results show that there is a critical time during pregnancy for the onset of anxiety in control rats, depending on the gestational stage. The exposure to different types of chronic stressors may result in distinct behaviors related to this disorder.

Abstract
Prenatal maternal stress (PNMS) in animals and humans predicts obesity and metabolic dysfunction in the offspring. Epigenetic modification of gene function is considered one possible mechanism by which PNMS results in poor outcomes in offspring. Our goal was to determine the role of maternal objective exposure and subjective distress on child BMI and central adiposity at 13½ years of age, and to test the hypothesis that DNA methylation mediates the effect of PNMS on growth. Mothers were pregnant during the January 1998 Quebec ice storm. We assessed their objective exposure and subjective distress in June 1998. At age 13½ their children were weighed and measured (n = 66); a subsample provided blood samples for epigenetic studies (n = 31). Objective and subjective PNMS correlated with central adiposity (waist-to-height ratio); only objective PNMS predicted body mass index (BMI). Bootstrapping analyses showed that the methylation level of genes from established Type-1 and -2 diabetes mellitus pathways showed significant mediation of the effect of objective PNMS on both central adiposity and BMI. However, the negative mediating effects indicate that, although greater objective PNMS predicts greater BMI and adiposity, this effect is dampened by the effects of objective PNMS on DNA methylation, suggesting a protective role of the selected genes from Type-1 and -2 diabetes mellitus pathways. We provide data supporting that DNA methylation is a potential mechanism involved in the long-term adaptation and programming of the genome in response to early adverse environmental factors.

Abstract
Research on the developmental origins of health and disease highlights the plasticity of the human fetus to a host of potential teratogens. Experimental research on laboratory animals has demonstrated a variety of physical and behavioral effects among offspring exposed to prenatal maternal stress (PNMS). However, these studies cannot elucidate the relative effects of the objective stress exposure and the subjective distress in a way that would parallel the stress experience in humans. PNMS research with humans is also limited because there are ethical challenges to designing studies that involve the random assignment of pregnant women to varying levels of independent stressors. Natural disasters present opportunities for natural experiments of the effects of pregnant women's exposure to stress on child development. In this review, we present an overview of the human and animal research on PNMS, and highlight the results of Project Ice Storm which has been following the cognitive, behavioral, motor and physical development of children exposed in utero to the January 1998 Quebec Ice Storm. We have found that both objective degree of exposure to the storm and the mothers' subjective distress have strong and persistent effects on child development, and that these effects are often moderated by the timing of the ice storm in pregnancy and by the child's sex.

Abstract
Research exploring the effects of prenatal maternal depression on a developing fetus and child is underrepresented in the literature. Empirical papers have typically focused on the effects of postpartum depression (after birth) instead of prepartum depression (before birth). Disparate empirical findings have produced ongoing debate regarding the effects of prenatal depression on a developing fetus and later in infancy and early childhood. Even more controversial is determining the role of antidepressant medication on offspring outcomes and whether research that does not include the proper control population (e.g., unmedicated depressed participants) can adequately address questions about risks and benefits of treatment during pregnancy. The current review systematically summarizes the literature focusing on unmedicated prenatal depression and offspring outcome and concludes that prepartum depression is highly prevalent, is associated with negative outcomes in offspring, and remains understudied.

Abstract
INTRODUCTION An adverse environment in utero, including exposure to prenatal maternal stress (PNMS), can result in poor birth outcomes such as low birth weight, which increases risk of later cardiometabolic diseases such as hypertension and obesity. It is unclear to what extent PNMS influences obesity risk independent of its impact on birth characteristics, especially among humans. Our objective was to determine whether PNMS resulting from a natural disaster influenced risk of childhood obesity. RESULTS Eight children with high objective PNMS exposure (14.5%) were obese compared to one child (1.8%) with low exposure (P = 0.02). Objective PNMS increased obesity risk (model 1, P = 0.02, odds ratio = 1.37) after controlling for other potential risk factors. DISCUSSION Results suggest that PNMS might be an independent risk factor in the development of childhood obesity. METHODS Participants included 111 women who were pregnant during the January 1998 Québec Ice Storm or who conceived within the following 3 months and their children. We tested associations between objective and subjective PNMS from the storm and childhood obesity status at age 5½, controlling for children's birth characteristics and breastfeeding status; household socioeconomic status; maternal obstetric complications, life events and smoking during pregnancy, psychological functioning, and height (model 1, n = 111) or BMI (for a subset of 69 participants, model 2).

Abstract
BACKGROUND Prenatal serotonin reuptake inhibitor (SRI) exposure has been related to adverse newborn neurobehavioral outcomes; however, these effects have not been compared to those that may arise from prenatal exposure to maternal major depressive disorder (MDD) without SRI treatment. This study examined potential effects of MDD with and without SRI treatment on newborn neurobehavior. METHODS This was a prospective, naturalistic study. Women were seen at an outpatient research center twice during pregnancy (26-28 and 36-38 weeks gestational age (GA)). Psychiatric diagnoses were assessed using the Structured Clinical Interview for the DSM-IV; medication use was measured with the Timeline Follow-Back instrument. Three groups were established based upon MDD diagnosis and SRI use: Control (N = 56), MDD (N = 20), or MDD + SRI (N = 36). Infants were assessed on a single occasion within 3 weeks of birth with the NICU Network Neurobehavioral Assessment Scale. Generalized Linear Modeling was used to examine neurobehavioral outcomes by exposure group and infant age at assessment. RESULTS Full-term infants exposed to MDD + SRIs had a lower GA than CON or MDD-exposed infants and, controlling for GA, had lower quality of movement and more central nervous system stress signs. In contrast, MDD-exposed infants had the highest quality of movement scores while having lower attention scores than CON and MDD + SRI-exposed infants. CONCLUSION MDD + SRI-exposed infants seem to have a different neurobehavioral profile than MDD-exposed infants in the first 3 weeks after delivery; both groups may have different neurobehavioral profiles with increasing age from birth.

Abstract
BACKGROUND Little is known about how anxiety disorders affect pregnancy outcomes. Therefore we investigated the impact of one anxiety disorder, blood- and injection phobia, on obstetric and neonatal outcomes. METHODS From a population-based prospectively collected cohort we compared an index group of 110 women with blood- and injection phobia with a control group of 220 women. Standardized medical records were used to collect data. Obstetric and neonatal outcomes e.g. elective cesarean, prematurity, and small for gestational age were used as the main outcome measures. RESULTS Women with blood- and injection phobia stated more often a fear of childbirth (p<0.001) and were more frequently delivered by elective cesarean section (p=0.032). The incidence of premature delivery (p=0.028), neonatal morbidity (p=0.001) and the risk of having a baby born small for gestational age (p=0.009) was higher among women with blood- and injection phobia. LIMITATIONS The medical records, from which all information is drawn, despite standardization, sometimes may lack some information. However, this dilemma exists in both groups. CONCLUSIONS Women with an anxiety disorder such as blood- and injection phobia are at increased risk for adverse obstetric outcomes, premature delivery and for having a baby born with higher neonatal morbidity. It therefore seems important to identify and treat women with anxiety disorders without delay early during pregnancy in an effort to minimize risks of complications for the woman herself and the child.

Abstract
Around 7% of pregnant women suffer from blood- and injection phobia. The aim was to investigate if cognitive behavior group therapy (CBT) is effective in treating pregnant women's blood- and injection phobia. Thirty pregnant women with blood- and injection phobia according to DSM-IV took part in an open treatment intervention. A two-session cognitive behavior group therapy was conducted. As controls, 46 pregnant women with untreated blood- and injection phobia and 70 healthy pregnant women were used. Repeated measures ANOVA were performed. The scores for the CBT treatment group on the "Injection Phobia Scale-Anxiety" were reduced both after each treatment session and postpartum (p < 0.001). Anxiety and depressive symptoms were also reduced (p < 0.001). Cognitive-behavior group therapy for pregnant women with blood- and injection phobia is effective and stable up to at least 3 months postpartum. It seems also to reduce anxiety and depressive symptoms during pregnancy.

Abstract
This study investigated the relationship between fetal movements and acute maternal emotional changes during pregnancy. Two empirically validated feature film clips were used for the external generation of two subjectively and facially well-characterized target emotions: happiness and sadness. We simultaneously monitored separate fetal arm, leg, and trunk movements by means of two ultrasound apparatuses while maternal emotions were manipulated by film clip presentation. The number of fetal arm movements, but not the duration, was increased when pregnant women were being shown a happy film. Both the number and the duration of fetal arm movements decreased with the sad film presentation. Neither the presentation of happiness nor the presentation of sadness affected fetal leg or trunk movements. These findings suggest that induced emotions in pregnant women primarily affect arm movements of their fetuses, and that positive and negative emotions have the opposite effects on fetus movement.

Abstract
The purpose of the study was to determine the specific periods during pregnancy in which human fetal exposure to stress hormones affects newborn physical and neuromuscular maturation. Blood was collected from 158 women at 15, 19, 25, and 31 weeks' gestation. Levels of placental corticotropin-releasing hormone (CRH) and maternal cortisol were determined from plasma. Newborns were evaluated with the New Ballard Maturation Score. Results indicated that increases in maternal cortisol at 15, 19, and 25 weeks and increases in placental CRH at 31 weeks were significantly associated with decreases in infant maturation among males (even after controlling for length of gestation). Results also suggested that increases in maternal cortisol at 31 weeks were associated with increases in infant maturation among females, although these results were not significant after controlling for length of gestation. Findings suggest that stress hormones have effects on human fetal neurodevelopment that are independent of birth outcome.

Abstract
OBJECTIVE The present study examined the impact of both perinatal maternal depression and cocaine use on infant neurobehavior at 1 month of age in a large, multi-site study. METHODS Infant neurobehavior was examined in 1053 infants at 1 month of age using the NICU Network Neurobehavioral Scale (NNNS). Mothers were interviewed using The Addiction Severity Index to determine present and past psychiatric history. Four groups were derived from the total sample: 385 prenatally cocaine-exposed infants, 76 whose mothers reported current postpartum depression (DEP/COC) and 309 without current postpartum depression (nonDEP/COC); 668 infants were not exposed to cocaine, 104 whose mothers reported current postpartum depression (DEP/nonCOC), 564 without current postpartum depression (nonDEP/nonCOC). A 2x2 Analysis of Covariance was used with covariates (birthweight, maternal age, SES, nicotine, alcohol, and research site) to examine infant neurobehavior in these four conditions. Secondary analyses were conducted to examine the effects of amount and timing of prenatal cocaine exposure. RESULTS DEP group by COC exposure status interactions were significant; there was only a DEP effect in the nonCOC infants. Infants in the nonCOC/DEP group had poorer self-regulation and more stress signs, excitability, and arousal than infants in the other groups. CONCLUSIONS Postpartum maternal depression has negative effects on infant neurobehavior at 1 month of age. Prenatal cocaine exposure may serve to suppress or buffer the effects of postpartum depression on infant neurobehavior. Maternal mood could explain some of the inconsistencies found in the prenatal cocaine exposure literature.

Abstract
Emerging data suggest that prenatal factors influence children's temperament. In 50 dyads, we examined fetal heart rate (FHR) activity and women's antenatal psychiatric illness as predictors of infant temperament at 4 months (response to novelty and the Infant Behavior Checklist). FHR change during maternal challenge was positively associated with observed infant motor reactivity to novelty (p = .02). The odds of being classified as high versus low motor among fetuses who had an increase in FHR during maternal stress was 11 times those who had a decrease in FHR (p = .0006). Antenatal psychiatric diagnosis was associated with an almost fourfold greater odds of having a high cry reactivity classification (p = .03). There also were modest associations between baseline FHR and maternal reports of infant temperament and between observed temperament and that based on mothers' reports. All of the infant results were found independent of the influence of women's postnatal anxiety. These data indicate that physiological markers of individual differences in infant temperament are identifiable in the fetal period, and possibly shaped by the prenatal environment.

Abstract
There is a need for a new pathophysiological model explaining and linking the role of numerous non-genetic factors believed to contribute to origins of many chronic physical diseases. This article presents a theoretical model for explaining the confusing and often contradictory findings regarding the role of environmental influences in type 1 diabetes, a disease that has been widely studied, for which clear diagnostic criteria exist, and for which development of effective prevention strategies represents significant challenges. The model is formulated from the large database of research regarding increasing understanding of the interaction between environmental factors, physiology, and autonomic regulatory function. Data is integrated from research in the fields of the experience-dependent maturation of the nervous system and the neurophysiology of traumatic stress to demonstrate how disruptions in early bonding and attachment, including adverse events such as traumatic stress, are capable of causing: (1) long-term imbalances in autonomic regulatory function and (2) relative dominance of sympathetic or parasympathetic activity. The proposed model of autonomic dysfunction suggests that ongoing mechanisms promoting high glucose in the context of decreasing insulin production in type 1 diabetes represent a state of relative sympathetic dominance influenced by environmental factors affecting autonomic, immune and endocrine systems during critical period programming. The model further identifies a link between the many seemingly unrelated non-genetic risk factors, and appears capable of explaining contradictions and enigmas in epidemiological and clinical studies regarding non-genetic origins of type 1 diabetes, including the role of stress, variation in age of onset, and duration of the preclinical phase.

Abstract
OBJECTIVE To review the literature on the perinatal risks involved in untreated depression during pregnancy. METHOD We searched Medline and medical texts for all studies pertaining to this area up to the end of April 2003. Key phrases entered were depression and pregnancy, depression and pregnancy outcome, and depression and untreated pregnancy. We did not include bipolar depression. RESULTS While there is wide variability in reported effects, untreated depression during pregnancy appears to carry substantial perinatal risks. These may be direct risks to the fetus and infant or risks secondary to unhealthy maternal behaviours arising from the depression. Recent human data suggest that untreated postpartum depression, not treatment with antidepressants in pregnancy, results in adverse perinatal outcome. CONCLUSION The biological dysregulation caused by gestational depression has not received appropriate attention: most studies focus on the potential but unproven risks of psychotropic medication. No in-depth discussion of the role of psychotherapy is available. Because they are not aware of the potentially catastrophic outcome of untreated maternal depression, this imbalance may lead women suffering from depression to fear teratogenic effects and refuse treatment.

Abstract
OBJECTIVE This is a prospective study of the effects of maternal use of selective serotonin reuptake inhibitors (SSRIs) during pregnancy on newborn neurobehavioral integrity, including systematic measures of behavioral state, sleep organization, motor activity, heart rate variability (HRV), tremulousness, and startles. METHODS The sample included 17 SSRI-exposed and 17 nonexposed, full-birth-weight newborn infants who had no obvious medical problems and were matched on maternal cigarette use, social class, and maternal age. SSRI exposure was determined by medical records and maternal self-report during a standard interview. Behavioral state, startles, and tremulousness were evaluated for 1 hour between feedings. Automated recordings of motor activity and HRV were also assessed during a 15-minute subset sleep period. HRV was subjected to spectral analysis to detect rhythms in autonomic regulation. Exposed and nonexposed infant groups were compared on measures of neurobehavioral development both before and after adjustment for gestational age as a covariate. RESULTS SSRI-exposed infants had a shorter mean gestational age; were more motorically active and tremulous; and showed fewer rhythms in HRV, fewer changes in behavioral state, fewer different behavioral states, and a lower peak behavioral state. SSRI-exposed infants also had significantly more rapid eye movement sleep, which was characterized by longer continuous bouts in that state and higher numbers of spontaneous startles or sudden arousals. After effects of gestational age were covaried, significant differences continued to be found in tremulousness and all measures of state and sleep organization, but effects on startles, motor activity, and rhythms in HRV were no longer significant. CONCLUSIONS Results provide the first systematic evidence that women who use SSRIs during pregnancy have healthy, full-birth-weight newborn infants who show disruptions in a wide range of neurobehavioral outcomes. Effects on motor activity, startles, and HRV may be mediated through the effects of SSRI exposure on gestational age. Future research can lead to a better understanding of the effects of SSRI use during pregnancy and an improved public health outcome.

Abstract
Stress increases corticotropin-releasing hormone and may ultimately result in increased uterine contractility. Stress also increases cytokine production, which independently may lead to preterm birth or increase susceptibility to infection, thereby increasing the risk of preterm birth. Finally, stress may change health behaviors that lead to preterm birth. Research findings on the relationship between stress and preterm birth have been contradictory. In this article, the authors propose a model of the relationship between stress and preterm birth, evaluate the research on stress and pregnancy outcomes, and discuss the implications for nursing practice and research.

Abstract
Treating women with psychiatric disorders during pregnancy is a challenge for numerous reasons. Balancing the risks and benefits of symptoms and treatments is particularly important during pregnancy because both medication and maternal illness may have adverse effects on the fetus. Communication of options in the management of psychiatric disorders in pregnancy is vital to optimal treatment. One barrier to effective communication has been a paucity of research from which clinicians can draw information, particularly in the area of pharmacological treatment. However, emerging evidence points to the low risk of many psychotropic medications during pregnancy. Uncertainty must not prevent frank risk-benefit discussions from occurring between treating physicians and their pregnant patients. Psychiatrists can prepare themselves for management decisions by reviewing the current literature.

Abstract
This study examined the effects of pregnant women's acute stress reactivity and chronic anxiety on fetal heart rate (HR). Thirty-two healthy third trimester pregnant women were instrumented to monitor continuous electrocardiography, blood pressure, respiration, and fetal HR. Subjects completed the trait anxiety subscale of the State Trait Anxiety Index, then rested quietly for a 5-minute baseline period, followed by a 5-minute Stroop color-word matching task and a 5-minute recovery period. Fetal HR changes during women's recovery from a stressful task were associated with the women's concurrently collected HR and blood pressure changes (r =.63, p <.05). Fetal HR changes during recovery, as well as during women's exposure to the Stroop task, were correlated with their mothers' trait anxiety scores (r =.39, p <.05 and r = -.52, p <.01, respectively). Finally, a combination of measures of women's cardiovascular activity during recovery and trait anxiety scores accounted for two thirds of the variance in fetal HR changes during the same recovery period (r =.69, p <.001). The results from this study link changes in fetal behavior with acute changes in women's cardiovascular activity after psychological stress and women's anxiety status. This indicates that variations in women's emotion-based physiological activity can affect the fetus and may be centrally important to fetal development.

Abstract
Although it is possible to demonstrate an influence of psychological factors on immune responses at any point in the life span, there are two periods when the effects may have greater implications for health. Our research with nonhuman primates indicates that the immaturity of a young infant's immune responses makes it more vulnerable, especially during the fetal and neonatal stages. Similarly, the natural, age-related process of immune senescence creates a second period of increased risk in elderly animals and people. This review summarizes findings from a 20-year research program, which support the conclusion that we should give special attention to the age of the host in psychoneuroimmunology studies.

Abstract
To better understand the effects of untreated maternal depression on the fetus, this study examined fetal heart rate (FHR) and FHR reactivity to vibroacoustic stimulation in pregnant women with untreated depression. The 20 participants were 32- to 36-week pregnant women divided into groups with depression (N = 10) and without depression (N = 10) based on the Beck Depression Inventory (BDI; Beck, 1977; Beck & Steer, 1987). Participants were attached to a fetal heart monitor, and 10 min of baseline FHR were recorded. A vibroacoustic stimulus (VAS) was presented, and an additional 10 min of FHR were recorded. Fetuses of mothers with depression had an elevated baseline FHR and a 3.5-fold delay in return to baseline FHR after VAS presentation. Additionally, mothers with depression had significantly higher anxiety levels and took fewer prenatal vitamins during pregnancy. Delayed habituation of FHR in the fetuses of mothers with depression may be due to alterations in the internal hormonal environment and could have implications for postnatal information processing.

Abstract
Substantial evidence from preclinical laboratory studies indicates that prenatal stress (PS) affects the hormonal and behavioural development of offspring. In the following review, the effects of PS in rodents and non-human primates on hypothalamic-pituitary-adrenal (HPA) reactivity to stress, morphological changes in the brain, motor behaviour and learning are surveyed. PS has been found to alter baseline and stress-induced responsivity of the HPA axis and levels and distribution of regulatory neurotransmitters, such as norepinepherine, dopamine, serotonin and acetylcholine and to modify key limbic structures. In rodents and non-human primates, PS affected learning, anxiety and social behaviour. The relevance of these findings to humans is discussed with respect to (a) the effect of administration of exogenous corticosteroids in pregnancy and (b) maternal state and trait anxiety during gestation and its relation to foetal autonomic regulation as putative predisposing factors in the pathogenesis of behavioural developmental delays in children.

Abstract
Physiological responses to stress during pregnancy are believed to influence birth outcomes. Researchers have studied pregnant women in laboratory stressor paradigms to investigate these associations, yet normative data on cardiovascular and respiratory responses to laboratory challenge during pregnancy are not yet established. To begin to establish such normative data, this study examined the effects of task and repeat stressor exposure on reactivity in third-trimester pregnant women. Thirty-one healthy pregnant women (mean age=27 years; range 18-36) between the 33rd and 39th week of pregnancy, were instrumented for continuous electrocardiography, blood pressure (BP), and respiration data. Subjects rested quietly for a 5-min baseline and then performed both a mental arithmetic stressor and a Stroop color-word-matching task, each 5 min in length and each followed by a 5-min recovery period. The order of the tasks was counterbalanced. After each 5-min period, subjects rated the period on a 10-point stress scale. Averaged across task type and challenge period, systolic and diastolic BP and respiration rate increased significantly in response to cognitive challenge, but heart rate (HR) did not. When data were examined for task and period effects, the following results emerged: the Stroop task elicited significantly greater systolic BP and HR reactivity than the arithmetic task, yet subjects rated the arithmetic task as more stressful. Averaged across task type, subjects showed greater systolic BP reactivity during the second challenge period compared to the first. Finally, women's BP tended to drift upward and did not return to baseline during the first recovery period. These findings indicate that averaging data across tasks and periods can obscure the time course of response patterns that may be important in the study of associations between maternal stress and perinatal development, as well as in other research on reactivity to repeat stress exposure.

Abstract
In this study, the authors hypothesized that life event stress is associated with an increased risk of spontaneous abortion. Using a nested case-control design in an emergency department (N = 970), stress was measured using a life event inventory and a sample drawn from R. B. Ness et al.'s (1999) Early Pregnancy Study. Gestational age at time of fetal loss served as a marker of chromosomal status. Women experiencing more than one life event used more alcohol and public assistance. Spontaneous abortion at 11 weeks or greater was associated with more life event stress (adjusted odds ratio 2.9, 95% confidence interval 1.4-6.2), whereas spontaneous abortion at any gestational age was not, implying that life event stress increases the risk of chromosomally normal spontaneous abortion. An analysis of confounders showed tobacco use was associated with an increased risk of spontaneous abortion, whereas prenatal care was only associated with fetal loss at 11 weeks or greater.

Abstract
Elevated concentrations of maternal corticotrophin-releasing hormone (CRH) during the 2nd and early 3rd trimester of human pregnancy are associated with spontaneous preterm birth, but the effects of maternal CRH on the fetus are unknown. Maternal plasma was collected for analysis of CRH concentration, m = 156.24 +/- 130.91 pg/ml, from 33 pregnant women during Weeks 31-33 of gestation. Immediately after collection of plasma, fetal heart rate (FHR) measures were obtained in response to a challenge with a series of vibroacoustic stimuli. Fetuses of mothers with highly elevated CRH did not respond significantly to the presence of a novel stimulus in a repeated series, p = 0.016. These effects on the FHR response were not related to parity, fetal gender, medical (antepartum) risk, or eventual birth outcomes. Impaired dishabituation in these fetuses of mothers with high concentrations of CRH suggests that neurological systems rich with CRH receptors that support learning and memory, such as parahippocampal regions, may be targets for maternal/placental CRH, with implications for fetal neurological development.

Abstract
Pregnancy is a time of great emotional change for a woman, producing increased stress and anxiety. Medication may be required for the treatment of anxiety disorders at this time. Given the fact that psychotropic drugs readily cross the placenta and could have important implications for the developing fetus, it is necessary to balance the possible effects of medication against the potential effects to both the mother and fetus if the anxiety disorder is left untreated. Despite the widespread use of psychotropic drugs such as benzodiazepines and antidepressants during pregnancy, there is a paucity of information regarding the effect of such exposure on the developing fetus. From a review of the literature it is clear that the issue of safety of psychotropic drugs during pregnancy is far from resolved. While some of the findings from animal studies are alarming, these studies cannot be directly extrapolated to humans. In addition, varying sample sizes and multiple drug exposures further complicate interpretation of human studies. Nonpharmacological treatments such as cognitive behavioural therapy should be employed whenever possible for the treatment of anxiety disorders during pregnancy. However, if medication is required pregnant women should be prescribed the lowest dosage for the minimum amount of time.

Abstract
OBJECTIVE Physiological processes including neuroendocrine function have been proposed as mediators of the relationship between prenatal psychological state and pregnancy outcome; however, there are virtually no human studies that have systematically assessed such mechanisms. Neuroendocrine processes are significantly altered during pregnancy, and are characterized by the evolution of a transient neuroendocrine system, the placenta, and modifications in endocrine control mechanisms. Because these alterations have implications for neuroendocrine responsivity to exogenous conditions, the aim of the present study was to examine the cross-sectional association between prenatal psychosocial factors and stress-related neuroendocrine parameters during human pregnancy. METHOD Fifty-four adult women with a singleton, intrauterine pregnancy were recruited before 28 weeks of gestation. Maternal antecubital venous blood samples were withdrawn at 28 weeks of gestation for bioassays of adrenocorticotropin hormone (ACTH), beta-endorphin (beta E), and cortisol. Measures of prenatal stress, social support, and personality were collected using a two-part, self-report questionnaire administered at 28 and 30 weeks of gestation. Biomedical data were obtained from the medical record. Factors known to influence neuropeptide and hormone levels during pregnancy were controlled, including gestational age, circadian variation, and obstetric risk. RESULTS In the present sample, prenatal psychosocial stress, social support, and personality variables were associated with neuroendocrine parameters in two primary ways. First, certain psychosocial factors were significantly associated with plasma levels of ACTH, beta E, and cortisol, and second, psychosocial factors were associated with a measure of disregulation of the normal relationship between two pro-opiomelanocortin (POMC) derivatives, ACTH and beta E. Furthermore, a combination of the maternal psychosocial and sociodemographic factors during pregnancy accounted for 36% of the variance in ACTH, 22% of the variance in the ACTH-beta E disregulation index, 13% of the variance in cortisol, and 3% of the variance in beta E. CONCLUSIONS The present findings are consistent with the premise that maternal-placental-fetal neuroendocrine parameters are significantly associated, both in magnitude and specificity, with features of maternal psychosocial functioning in pregnancy despite the systemic alterations associated with the endocrinology of pregnancy. These findings provide a basis for further investigations of the role of the neuroendocrine system as a putative mediating pathway between prenatal psychosocial factors and birth outcome, and possibly also as a mechanism linking features of the maternal psychosocial environment to fetal/infant brain development.

Abstract
OBJECTIVE The objective was to test the prospective association between prenatal maternal circulatory responses to a standardized psychologic challenge and birth outcome. STUDY DESIGN We examined the relationship between blood pressure responses to a cognitive arithmetic stressor and birth outcome in 40 healthy primigravid women. Pregnant women between 18 and 37 years old were recruited from the University of Kentucky Prenatal Service Clinic for participation. All women performed an interactive arithmetic task while maternal heart rate and blood pressures were determined. Subsequent birth outcome parameters of birth weight and gestational age were obtained for prospective analyses. RESULTS Results indicated that maternal systolic and diastolic blood pressures and heart rates were significantly increased during the arithmetic task (p < or = 0.01). Regression analyses suggested that women with larger diastolic blood pressure responses during stress had infants with lower birth weights (p < 0.01) and decreased gestational age (p < 0.05). CONCLUSIONS This effect was specific to psychologic stress reactivity and was not related to maternal age, maternal race, baseline blood pressures, the trimester of stress testing, nor expired carbon monoxide. The relationship between maternal blood pressure response and birth outcome may reflect the transplacental impact of individual differences in systemic stress responsivity.

Abstract
In this review of articles on prenatal stress, anxiety, development, and reproductive health outcomes in pregnancy, the focus is on recent research in which the relationships among the major types of stressors, anxiety, and development, on the one hand, and maternal, fetal, and neonatal problems or complications, on the other hand, were examined. Available and effective treatment measures, although limited, are introduced and discussed at length in a follow-up article. Recommendations for policy development based on current research and treatment methods and directions for future research and treatment studies are presented in a third article.
