Prenatal depression

Family physicians are uniquely situated to play a major role in postpartum care. Postpartum issues that should be monitored and addressed include reproductive and contraceptive planning, breastfeeding counseling and support, and maternal mental health. All women should be screened for postpartum depression using a validated tool at the postpartum visit and/or at well-child visits. Patients with positive screening results should be offered support and treatment. Women are more likely to breastfeed if they are provided with breastfeeding support and counseling routinely during the prenatal and postpartum periods...

BACKGROUND: Prenatal stress (PS) exposure can cause depression-like behavior in offspring, and maladaptive responses including physiological and neurobiological changes. Glutamate neurotransmission is implicated in effects of PS and in antidepressant mechanisms; however, the mechanisms underlying its involvement remain unclear. In the synapse, the formation of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex is essential for vesicular docking and neurotransmitter release...

Prenatal vitamin D deficiency and prenatal depression are both separately associated with adverse perinatal outcomes; however, to our knowledge no studies have investigated the effects of having both risk factors. Our objective was to determine to what extent vitamin D deficiency predicts adverse perinatal outcomes and whether elevated depressive symptoms in pregnancy places women at additional increased risk. This study was a secondary data analysis of prospective data collected from a cohort of pregnant women (N = 101) in an obstetric clinic of a large medical center...

METHODS: We studied associations between prenatal exposure to particulate matter with diameter ≤ 2.5 μm (PM2.5) and postpartum psychological functioning in a lower income, ethnically mixed sample of urban US women enrolled in a pregnancy cohort study. Analyses included 557 mothers who delivered at ≥37 weeks gestation. Daily estimates of residential PM2.5 over gestation were derived using a satellite-based spatio-temporally resolved model. Outcomes included the Edinburgh Postnatal Depression Scale (EPDS) score from 6 or 12 months postpartum and subscale scores for anhedonia, depressive and anxiety symptoms...

OBJECTIVES: The purpose of this study was to explore the socio-demographic and psychological factors connected with exclusive breastfeeding after 6 months postpartum. MATERIAL AND METHODS: A total of 251 women filled in questionnaires in the first week postpartum, then again after 3 and 6 months. The questionnaires included socio-demographic and medical questions, as well as psychological tools: the NEO-FFI Personality Inventory, the Berlin Social Support Scales (BSSS), and the Edinburgh Postnatal Depression Scale (EPDS)...

Childbirth is an important life event that has been understudied by psychologists. Parents may find birth to be stressful, painful, and frightening, or feel supported and calm. Birth experiences can be shaped both by preexisting psychological vulnerabilities and by medical events that occur during childbirth. The birth experience may influence both parent and child well-being, helping to shape the health of the new family. This paper introduces the Birth Experiences Questionnaire (BEQ), a brief 10-item measure designed to assess stress, fear, and partner support during birth...

BACKGROUND: Most evidence of the association between maternal depression and children's development is limited by being cross-sectional. To date, few studies have modelled trajectories of maternal depressive symptoms from pregnancy through the early postpartum years and examined their association with social emotional and behavior functioning in preschool children. The objectives of this study were to: 1) identify distinct groups of women defined by their trajectories of depressive symptoms across four time points from mid-pregnancy to one year postpartum; and 2) examine the associations between these trajectories and child internalizing and externalizing behaviors...

BACKGROUND: We sought to describe the correlates of marijuana use during and after pregnancy, and to examine the independent relationship between prenatal marijuana use and infant outcomes. STUDY DESIGN: We used state-specific data from the Pregnancy Risk Assessment Monitoring System (N = 9013) to describe correlates of self-reported prenatal and postpartum marijuana use. We estimated differences in mean infant birth weight and gestational age among prenatal marijuana users and nonusers, controlling for relevant covariates (i...

Increasing evidence has shown that prenatal stress (PS) could cause depression-like behavior in the offspring, which is sex-specific. However, the underlying mechanisms remain to be elucidated. This study is to investigate the involvement of tryptophan hydroxylase 2 (Tph2) H3K9 acetylation (H3K9ac) modification on PS-induced depression-like behavior in juvenile offspring rats (JOR). PS models were established, with or without trichostatin A (TSA) treatment. Animal behavior was assessed by the sucrose preference test (SPT) and forced swimming test (FST)...

INTRODUCTION: Little is known of late adolescent Texas Latinas' prenatal care perceptions or how these perceptions predict timely prenatal care initiation or adequate utilization. Hence, the purpose of this study is to describe and compare these perceptions between participants with timely versus late prenatal care initiation and adequate, intermediate, and inadequate prenatal care utilization; and to determine predictors of timely prenatal care initiation and adequate utilization. METHODS: Fifty-four postpartum Latinas were recruited through social media...

Maternal postnatal depression has been associated with a broad range of developmental risk among children. However, there has been less focus on disentangling the effects of pre- and postnatal depressive symptoms, as well as examining the symptoms of both parents. This study aims to investigate the separate effects of pre- and postnatal depressive symptoms in mothers and fathers, and parents' differential effects on child social-emotional, cognitive, and language development at 18 months of age. Further, we investigate whether effects of depressive symptomatology on child outcomes are particularly strong when both parents evinced high symptom loads and whether parenting stress mediates associations between perinatal depressive symptoms and child developmental outcomes...

The exposure to supra-physiological levels of glucocorticoids in prenatal life can lead to a long-term impact in brain cytoarchitecture, increasing the susceptibility to neuropsychiatric disorders. Dexamethasone, an exogenous glucocorticoid widely used in pregnant women in risk of preterm delivery, is associated with higher rates of neuropsychiatric conditions throughout life of the descendants. In animal models, prenatal dexamethasone exposure leads to anxious-like behavior and increased susceptibility to depressive-like behavior in adulthood, concomitant with alterations in neuronal morphology in brain regions implicated in the control of emotions and mood...

Prenatal environment reportedly affects the programming of developmental trajectories in offspring and the modification of risks for later morbidity. Among the increasingly studied prenatal exposures are maternal psychological distress (PD) and altered maternal hypothalamus-pituitary-adrenal (HPA) axis functioning. Both prenatal PD and maternal short-term cortisol concentrations as markers for HPA axis activity have been linked to adverse child outcomes and it has been assumed that maternal PD affects the offspring partially via altered cortisol secretion patterns...

Epigenetic DNA modifications in genes related to the hypothalamic-pituitary-adrenal (HPA) axis are discussed as a mechanism underlying the association between prenatal depression and altered child HPA activity. In a longitudinal study, DNA methylation changes related to prenatal depressive symptoms were investigated in 167 children aged 6 to 9 years. At six candidate genes, 126 cytosine-guanine dinucleotides were considered without correcting for multiple testing due to the exploratory nature of the study. Further associations with the basal child HPA activity were examined...

Dysregulation of the hypothalamic-pituitary-adrenal (HPA) stress response has been suggested to play a role in vulnerability to stress-related disorders, such as depression. Prenatal alcohol exposure (PAE) may result in HPA dysregulation, which in turn may predispose individuals to the effects of stress exposure throughout life, and increase their risk of developing depression compared to unexposed individuals. We examined the immediate and delayed effects of chronic unpredictable stress (CUS) in adulthood on behavior of PAE animals in the forced swim test (FST) and the neurocircuitry underlying behavioral, emotional, and stress regulation...

This study aimed to assess the longitudinal prevalence of prenatal and postnatal depression and associated factors among HIV-infected women in rural South Africa. In a longitudinal, cluster-randomized, prevention of mother to child transmission (PMTCT) intervention trial, 681 HIV-infected prenatal women in 12 community health centres in Mpumalanga province, South Africa, were recruited in 2015 by consecutive sampling at 8-24 weeks pregnancy and followed up at 32 weeks prenatally, and 6 and 12 months postpartum (retention rate = 59...

BACKGROUND: Evidence shows that diet contributes substantially to lifelong physical and mental health. Although dietary exposure during gestation and early postnatal life is critical, human epidemiological data are limited regarding its link with children's subsequent externalizing issues. The aim of this study was to investigate the role of maternal diet during pregnancy in offspring's symptoms of hyperactivity-inattention and conduct problems from ages 3 to 8 years. METHODS: We used data of 1,242 mother-child pairs from a French cohort followed up from pregnancy until the children were 8 years of age...

OBJECTIVE: To evaluate the association of intimate partner violence during the gestational period and the development of externalizing and internalizing behavioral problems in children and adolescents. SOURCE OF DATA: A meta-analysis of cohort and case-control studies was performed, using studies selected from electronic databases. Eligible studies included women who experienced intimate partner violence during pregnancy and their children's behavioral problems...

INTRODUCTION: Obesity is a risk factor for adverse physical health outcomes during pregnancy. Much less is known about the association between obesity and maternal mental health. Evidence suggests that prenatal depression is associated with excessive weight gain during pregnancy and that this relationship may vary according to pregravid body mass index (BMI). Young women may be particularly vulnerable to postpartum depression. The objective of this study is to examine the association between prepregnancy BMI, gestational weight gain, and postpartum depressive symptoms among adolescents...

STUDY QUESTION: How does the psychological well-being and prenatal bonding of Indian surrogates differ from a comparison group of mothers? SUMMARY ANSWER: Surrogates had higher levels of depression during pregnancy and post-birth, displayed lower emotional connection with the unborn baby, and greater care towards the healthy growth of the foetus, than the comparison group of mothers. WHAT IS ALREADY KNOWN: Studies in the West have found that surrogates do not suffer long-term psychological harm...
