The program of psychological and breastfeeding support "Maternity step by step": an example of effective solution for the prevention, diagnostics and treatment of prenatal and postpartum depression

OBJECTIVES

Postpartum depression affects about 13-20% of women. Depression during pregnancy is observed in 19% of pregnant women. In Poland we lack asupport system for this group of patients. This article presents the elements of the pilot program of psychological interventions and breastfeeding support "Motherhood: step by step", financed by the municipality of Gdansk. The aim of the program was to provide inhabitants of Gdansk with professional breastfeeding support and psychological help during pregnancy and in the first year of infant's life.

METHODS

The study involved three groups of women: 36 mothers participating in psychological consultations and short-term therapy, 123 women from breastfeeding support group and 104 women in the control group. The evaluation was based on questionnaires prepared by the researchers, the General Health Questionnaire-28 and the Parenting Stress Index -3rd version.

RESULTS

The evaluation showed a significant decrease in symptoms of mental disorders in both groups of treated women: women from psychological intervention and breastfeeding intervention group. In women from psychological intervention group a significant decrease in parental stress was observed.

CONCLUSIONS

Conducted analyses showed that the implemented program is characterized by high effectiveness and may be recommended for the continuation in the subsequent years. It may be considered as asolution for changes in the new standards for perinatal care in Poland.

Mother's prenatal and postpartum depression symptoms and infant's sleep problems at 6 months

Mother's prenatal and postpartum depression have been associated with infant's sleep problems. This study aimed to analyze (a) the effects of mother's prenatal and postpartum depression symptoms, including the effects of prenatal and postpartum anxiety and depression scores of the Edinburgh Postnatal Depression Scale (EPDS), on infant's sleep problems at 6 months, and (b) the interaction effect between mother's prenatal and postpartum depression symptoms and infant's sex on infant's sleep problems at 6 months. The sample was comprised of 164 mother-infant dyads whose mothers completed measures of depression at the third trimester of pregnancy, 2 weeks, 3 and 6 months postpartum and a measure of infant's sleep problems at 6 months (CSHQ-I). Mother's prenatal depression symptoms, specifically depression scores of the EPDS, predicted more infant's sleep anxiety and daytime sleepiness, while mother's depression symptoms at 2 weeks postpartum, specifically anxiety scores of the EPDS, predicted more bedtime resistance and CSHQ-I total scores at 6 months. Boys of mothers with more prenatal depression symptoms presented more sleep anxiety at 6 months. Both mother's prenatal and early postpartum depression symptoms have a negative effect on the emergence of infant's sleep problems. Additionally, boys seem more vulnerable to mother's prenatal depression symptoms.

Genome-Wide DNA Methylation Patterns in Children Exposed to Nonpharmacologically Treated Prenatal Depressive Symptoms: Results From 2 Independent Cohorts

BACKGROUND

Maternal depressive symptoms are a common phenomenon during pregnancy and are related to negative outcomes for child development and health. Modifications in child DNA methylation are discussed as an underlying mechanism for the association between prenatal depressive symptoms and alterations in child outcomes. However, formerly reported genome-wide associations have yet to be replicated.

METHODS

In an epigenome-wide association study (EWAS), alterations of DNA methylation related to maternal prenatal depressive symptoms were investigated in buccal cell samples from 174 children (n = 52 exposed to prenatal depressive symptoms; 6-9 years old) of the German longitudinal study FRAMES-FRANCES. Whole blood samples from the independent, age-comparable ARIES subsample of the ARIES/ALSPAC study (n = 641; n = 159 exposed to prenatal depressive symptoms; 7-8 years old) were examined as a confirmation sample. Depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale. DNA methylation was analyzed with the Infinium Human Methylation 450k BeadChip. Modifications in single CpGs, regions, and biological pathways were investigated. Results were adjusted for age and birth outcomes as well as postnatal and current maternal depressive symptoms. Analyses were performed for the whole sample as well as separated for sex.

RESULTS

The EWAS yielded no differentially methylated CpG or region as well as no accordance between samples withstanding correction for multiple testing. In pathway analyses, no overlapping functional domain was found to be enriched for either sample. A comparison of current and former findings suggests some overlapping methylation modifications from infancy to childhood. Results suggest that there might be sex-specific differential methylation, which should be further investigated in additional studies.

CONCLUSIONS

The current, mainly nonsignificant, results challenge the assumption of consistent modifications of DNA methylation in children exposed to prenatal depressive symptoms. Despite the relatively small sample size used in this study, this lack of significant results may reflect diverse issues of environmental epigenetic studies, which need to be addressed in future research.

Prenatal Depression and Risk of Short Interpregnancy Interval in a Predominantly Puerto Rican Population

Background: Short interpregnancy interval (IPI) is associated with risk of adverse pregnancy outcomes; however, few studies have evaluated the role of depression as a risk factor for short IPI. Puerto Rican women in the United States experience disparities in adverse birth outcomes and have the highest birth rates. Methods: We analyzed the association between prenatal depressive symptoms and IPI in Proyecto Buena Salud, a prospective cohort of predominantly Puerto Rican women in Western Massachusetts (2006-2011). Depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) in early, mid, and late pregnancy. We calculated follow-up time as the difference between the date of delivery of the index pregnancy and the last menstrual period of the subsequent pregnancy using medical records and billing data. We defined short IPI as ≤18 months. Results: Of 1262 eligible women, 35% (n = 440) had at least probable minor depression (EPDS scores ≥13) and 25% (n = 315) had probable major depression (EPDS scores ≥15). Participants were followed for a median of 3.7 years (interquartile range = 1.4-6.0 years) and 240 (20.6%) participants experienced a short IPI. After adjusting for risk factors, women with probable minor depression (adjusted odds ratio [aOR] = 1.39, 95% confidence interval [CI] = 1.02-1.88) and probable major depression (aOR = 1.42, 95% CI = 1.02-1.97) during pregnancy had increased odds of short IPI. Conclusions: Prenatal depressive symptoms were common in this Puerto Rican population and were associated with a modest increase in odds of short IPI. Further examination of the pathways through which mental health may affect IPI in vulnerable populations is warranted.

Prevalence of Prenatal Depression Among Pregnant Women and the Importance of Resilience: A Multi-Site Questionnaire-Based Survey in Mainland China

BACKGROUND

Prenatal depression is associated with adverse maternal and fetal health consequences, yet it has not raised sufficient concerns in China. Psychological worries and stress may lead to prenatal depression, but resilience could relieve some of the negative effects of worries and stress and mitigate prenatal depression.

AIMS

This study aimed to assess the prevalence of prenatal depression and explore its associated factors.

METHOD

A multisite cross-sectional study was conducted that included 605 pregnant women from three hospitals in two provincial capitals (Shenyang and Zhengzhou) and one municipality (Chongqing). A smartphone questionnaire was employed to assess prenatal depression using the Center for Epidemiologic Studies Depression Scale (CES-D). Multivariate logistic regression analysis was performed to explore factors associated with prenatal depression.

RESULTS

The prevalence of prenatal depression (CES-D≥16) among Chinese pregnant women was 28.4%. Logistic regression analyses revealed that prenatal depression was positively associated with worries about appearance (odds ratio [OR] 1.666, 95% confidence interval [CI] 1.043-2.661) and perceived stress (OR 1.156, 95% CI 1.104-1.211) and negatively associated with monthly income, relationship with mother (OR 0.287, 95% CI 0.103-0.796), and resilience (OR 0.935, 95% CI 0.918-0.953).

CONCLUSION

These findings revealed that Chinese pregnant women suffered from high levels of prenatal depression (28.4%). Worries about appearance and perceived stress were risk factors for prenatal depression, whereas a pregnant woman's harmonious relationship with her own mother and resilience could relieve the negative impacts of pregnancy that can lead to prenatal depression. Improving resilience and maintaining harmonious relationships with mothers should be emphasized in order to reduce the detrimental effects of pregnancy and improve the mental well-being of pregnant women.

Prevalence and Risk Factors for Self-Reported Postpartum Depression Symptoms (SRPDS) in Hawai'i, 2012-2015

Postpartum depression (PPD) affects an estimated 10% to 20% of women in the United States, but little is known about the risk factors for PPD in Hawai'i. This study sought to identify PPD risk factors and examine whether disparities exist in Hawai'i. Aggregated 2012-2015 Hawai'i Pregnancy Risk Assessment Monitoring System (PRAMS) data from 5572 women with a recent live birth were analyzed. Two questions on the PRAMS survey about mood and interest in activities were used to create a brief measure of Self-Reported Postpartum Depression Symptoms (SRPDS). Multivariate generalized logit analysis was conducted to identify risk factors associated with SRPDS or possible SRPDS, adjusting for maternal race and age, intimate partner violence (IPV), prenatal anxiety, prenatal depression, illicit drug use before pregnancy, and stressful life events (SLEs). About 10.0% of women surveyed had SRPDS and 27.7% had possible SRPDS. SRPDS was more common among Native Hawaiians (adjusted odds ratios=1.77; 95% confidence interval: 1.17-2.70), Filipinos (2.16; 1.33-3.50), Japanese (2.88; 1.67-4.98), and other Pacific Islanders (OPI; 3.22; 1.78-5.82), when compared to white. Women aged 20-29 years (0.39; 0.24-0.65) and 30-52 years (0.41; 0.24-0.69) were less likely to have SRPDS than those 19 years and younger. SRPDS was highest among women who experienced IPV (2.65; 1.37-5.13), prenatal anxiety (2.10; 1.28-3.42), prenatal depression (2.78; 1.47-5.25), or used illicit drugs before pregnancy (1.97; 1.21-3.20). There was an upward trend in SRPDS based on the number of SLEs. Possible SRPDS had similar but smaller effects, suggesting the importance of clinical screening and appropriate follow-up for these high-risk groups.

The Effect of Maternal Depression on Infant Attachment: A Systematic Review

Aims and objectives: The aim of this systematic review was to summarize the key findings of empirical studies assessing the influence of maternal depression on child attachment security measured before 24 months after birth. Method: The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. A literature search was conducted on the EBSCO (Academic Search Complete; Health Source: Nursing/Academic Edition; MEDLINE; PsycARTICLES) and PubMed databases, with infant attachment AND depression as search terms with Boolean operators. Study design or sample size did not affect inclusion. After screening, 29 of the 1510 unique publications originally identified were included in the review. Results: The studies reveal an equivocal association between maternal depression and child attachment security. Our findings indicate that depression had a significant influence on the attachment style almost only when diagnosed by structured interview: Depression measured by self-descriptive questionnaires was unrelated to attachment style. Furthermore, postpartum depression was found to be significant only when measured up to six months after childbirth. Conclusion: The relationship between maternal depression and infant attachment is both complex and dynamic, and the possible negative effects of depression might be compensated by maternal involvement in childcare. Therefore, further studies in this area should employ a reliable methodology for diagnosing depression and a suitable time point for measuring it; they should also adopt a multifactorial and prospective approach. It is important to note that breastfeeding/formula feeding was omitted as a factor in the majority of studies.

Prenatal Attachment and Perinatal Depression: A Systematic Review

Pregnancy is a period of complex bio-psychological changes, during which the development of an attachment bond to the fetus takes on a central role. Depressive symptoms are common during this period. Both symptoms of depression and low levels of prenatal attachment are related to negative outcomes in caregivers and infants. Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement, this systematic review analyzes and systematizes 41 studies concerning the association between prenatal attachment and perinatal depression. The majority of the studies reported a significant association between the two. Specifically, prenatal depressive symptoms were found to be negatively associated with prenatal attachment. Furthermore, lower levels of prenatal attachment were related to higher postnatal depressive symptoms, although fewer studies assessed this association. While these results were found across different populations, conflicting findings emerged, suggesting they should be interpreted with caution, particularly in male samples and in non-normative pregnancies (e.g., high-risk pregnancies, medically assisted pregnancies, and pregnancies with previous perinatal losses). These results are clinically important for the perinatal screening process and for implementing preventive and treatment programs. However, future studies are needed to further confirm and generalize these results.

Placental glucocorticoid receptors are not affected by maternal depression or SSRI treatment

Background: Prenatal depression is common, with an estimate that up to one in five pregnant women suffers from depressive symptoms. Maternal depression is associated with poor pregnancy outcomes such as preterm birth and low birth-weight. Such outcomes possibly affect offspring development. Previous studies suggest placental RNA levels of the glucocorticoid receptor are altered by maternal depression or anxiety; this stress may affect the placenta of male and female foetuses differently. However, it is unknown if the protein levels and activity of this receptor are additionally affected in women with depressive symptoms or being pharmacologically treated for depression.Methods: In this study, we investigated whether the glucocorticoid receptor (NR3C1) in the placenta is affected by maternal depression and/or selective serotonin reuptake inhibitor (SSRIs) treatment. Placentas from 45 women with singleton, term pregnancies were analysed by Western blot to determine glucocorticoid receptor levels, and by DNA-binding capacity to measure glucocorticoid receptor activation.Results: There were no differences in levels of the glucocorticoid receptor or activity between groups (control, depressive symptoms, and SSRI treatment; n = 45). Similarly, there was no difference in placental glucocorticoid receptor levels or activity dependent upon foetal sex.Conclusion: Maternal depression and SSRI treatment do not affect the glucocorticoid receptors in the placenta.

Mediating Role of Labor on the Relationship Between Prenatal Psychopathologic Symptoms and Symptoms of Postpartum Depression in Women Who Give Birth Vaginally

OBJECTIVE

To investigate how prenatal symptoms of anxiety and depression and clinical aspects of labor (duration of labor, administration of oxytocin and epidural analgesia) interact with each other to contribute to symptoms of postpartum depression in women who give birth vaginally.

DESIGN

A longitudinal design with measurement at three different time points: Time 1, 31 to 32 weeks gestation; Time 2, the day of labor and birth; and Time 3, 1 month after birth.

SETTING

Maternity ward of the Misericordia e Dolce Hospital in Prato, Italy.

PARTICIPANTS

A total of 186 women at 31 to 32 weeks gestation were recruited during childbirth preparation courses at the maternity ward.

METHODS

At Time 1, women completed the Beck Depression Inventory and the State portion of the State-Trait Anxiety Inventory. At Time 2, midwives recorded clinical data related to labor, including duration of labor and administration of oxytocin and epidural analgesia. At Time 3, the women completed the Edinburgh Postnatal Depression Scale. Structural equation modeling was performed.

RESULTS

Symptoms of depression (β = 0.36; p < .001; 95% confidence interval [CI] [0.17, 0.49]) and state anxiety (β = 0.25; p < .001; 95% CI = [0.04, 0.27]) during pregnancy positively affected symptoms of depression after birth. Greater levels of these prenatal symptoms predicted a more complicated labor (depression: β = 0.29; p < .01; 95% CI [0.00, 0.19]; anxiety: β = 0.30; p < .01; 95% CI [0.01, 0.14]), which, in turn, positively predicted greater levels of symptoms of depression at 1 month after birth (β = 0.34; p < .001; 95% CI [0.38, 1.51]). Moreover, results highlighted indirect effects that high levels of anxiety symptoms during pregnancy have on postpartum symptoms of depression through the clinical aspects of labor (β = 0.10; p < .01; 95% CI [0.00, 0.13]). These indirect effects were not significant for antenatal symptoms of depression (β = 0.10; p < .05; 95% CI [-0.02, 0.20]).

CONCLUSION

Our findings confirm that symptoms of anxiety and depression during pregnancy represent significant risk factors for the clinical aspects of labor and for the development of symptoms of postpartum depression in the first month after childbirth.

Prenatal Depression and Its Associated Risk Factors Among Pregnant Women in Bangalore: A Hospital Based Prevalence Study

Background: Depression is the commonest psychological problem that affects a woman during her perinatal period worldwide. The risk of prenatal depression increases as the pregnancy progresses and clinically significant depressive symptoms are common in the mid and late trimester. There is a paucity of research on depression during the prenatal period in India. Given this background, the present study aimed to assess the prevalence of prenatal depression and its associated risk factors among pregnant women in Bangalore, Southern India. Methods: The study was nested within an on-going cohort study. The study participants included 280 pregnant women who were attending the antenatal clinic at Jaya Nagar General Hospital (Sanjay Gandhi Hospital) in Bangalore. The data was collected by using a structured questionnaire which included. Edinburgh Postnatal Depression Scale (EPDS) to screen for prenatal depression. Results: The proportion of respondents who screened positive for prenatal depression was 35.7%. Presence of domestic violence was found to impose a five times higher and highly significant risk of developing prenatal depression among the respondents. Pregnancy related anxiety and a recent history of catastrophic events were also found to be a positive predictors of prenatal depression. Conclusion: The high prevalence of prenatal depression in the present study is suggestive of its significance as a public health problem. Health care plans therefore can include screening and diagnosis of prenatal depression in the antenatal care along with other health care facilities provided.

Physical discomfort in early pregnancy and postpartum depressive symptoms

PURPOSE

Pregnancy examinations conducted in general practice focus mainly on identifying high-risk pregnancies and pregnancy complications. The pregnancy health record has a biomedical focus, and consequently the woman's mental well-being may receive less attention. The aim of this study was to evaluate the extent to which early pregnancy-related symptoms should be considered as indicators of an increased risk of postpartum depression.

MATERIALS AND METHODS

For a prospective cohort of 1508 pregnant women, the presence of 11 pregnancy-related symptoms was recorded at the first prenatal care consultation together with background information about socio-demography and health. Depression was assessed 8 weeks postpartum with the major depression inventory (MDI) and depression was considered present if MDI > 20. Multivariable logistic regression was used to assess the association between pregnancy-related symptoms and postpartum depressive symptoms, and to adjust for potential confounders.

RESULTS

A high depression score (MDI score >20) 8 weeks postpartum was found among 6.6% of the women and showed apparent associations with physical discomfort in early pregnancy, such as back pain and pelvic cavity pain. Analysis of confounding revealed, however, that signs of vulnerable mental health, present in early pregnancy, explained most of these associations.

CONCLUSIONS

Indicators of an increased risk of postpartum depressive symptoms may be found in early pregnancy. Pregnancy-related pain in the first trimester may be a sign of psychological vulnerability or an aspect of an existing depressive state that calls for attention.

TNF-α Polymorphisms and Maternal Depression in a Mexican Mestizo Population

BACKGROUND

Depressive disorders are common during pregnancy. There is compelling evidence that the inflammatory response system is important in the pathophysiology of depression. Higher concentrations of proinflammatory cytokines including tumor necrosis factor-alpha (TNF-α) in depressed subjects have been described. Because several polymorphisms in the TNF-α promoter region are known to affect its gene expression, the aim of this study was determine whether TNF-α - 857C/T, -308G/A, and -238G/A polymorphisms confer susceptibility to depression during pregnancy in a Mexican mestizo population.

METHODS

This case-control study involved 153 depressed pregnant women and 177 controls. Polymorphisms were genotyped using real-time PCR. Odds ratios (OR) and 95% confidence intervals adjusted by age, body mass index, number of pregnancies, months of pregnancy and number of abortions were used to estimate risk.

RESULTS

The -857CT genotype was found to increase the risk for depression (OR= 1.73, 95% CI= 1.06-2.82). In contrast, the -238GA genotype reduced the risk (OR= 0.33, 95% CI= 0.14-0.72). The - 308G/A polymorphism was not associated with risk for depression. Finally, the C857-G308-A238 haplotype was associated with a decreased risk of depression (OR= 0.35, 95% CI= 0.15-0.82).

CONCLUSION

Our results show for the first time an association between TNF-α -857C/T and -238G/A polymorphisms and prenatal depression in Mexican mestizo population.

Associations of prenatal depressive symptoms with DNA methylation of HPA axis-related genes and diurnal cortisol profiles in primary school-aged children

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. Children exposed to prenatal depressive symptoms exhibited lower bedtime cortisol (p = .003, ηp2 = 0.07) and a steeper diurnal slope (p = .023, ηp2 = 0.06). For total cortisol release, prenatal exposure was related to lower cortisol release in boys, and higher release in girls. Furthermore, prenatal depressive symptoms were associated with altered methylation in the glucocorticoid receptor gene (NR3C1), the mineralocorticoid receptor gene (NR3C2), and the serotonin receptor gene (SLC6A4), with some sex-specific effects (p = .012-.040, ηp2 = 0.03-0.04). In boys, prenatal depressive symptoms predicted bedtime cortisol mediated by NR3C2 methylation, indirect effect = -0.07, 95% confidence interval [-0.16, -0.02]. Results indicate relations of prenatal depressive symptoms to both child basal HPA activity and DNA methylation, partially fitting a mediation model, with exposed boys and girls being affected differently.

Pregnancy planning, timing, happiness and depressive symptoms among low-income women living with and without HIV

OBJECTIVE

This study assessed associations of sociodemographic factors and pregnancy intent and wantedness with pregnancy happiness and prenatal depressive symptoms and the relationship between prenatal depressive symptoms and pregnancy happiness.

BACKGROUND

Depression is the leading cause of disability world-wide and more so for women. Women are most likely to experience depression in their child bearing years, including during pregnancy. Untreated prenatal depression, associated with unwanted pregnancies endangers the health and wellbeing of the mother and her child. Research on the association of prenatal depression with pregnancy happiness among women with low incomes in the U.S.A. is limited. For women living with HIV, associations among family planning factors, pregnancy feelings and prenatal depression have been understudied.

METHODS

Sixty-four women living with HIV and 194 HIV-negative low-income pregnant women receiving care in a public university-based ob-gyn clinic with integrated HIV-care in Philadelphia between 2009 and 2012 participated in the study. The women completed a questionnaire on sociodemographic and pregnancy factors and the Center for Epidemiological Studies Depression Scale (CES-D). The independent associations of sociodemographic and pregnancy factors with pregnancy happiness and associations of these factors and pregnancy happiness with the CES-D were assessed using multivariable linear regressions.

RESULTS

Women who felt the pregnancy was too soon were less happy being pregnant (p < 0.01). Prenatal depressive symptoms were inversely associated with happiness with being pregnant and completing high school (p < 0.001 for both).

CONCLUSION

Health care professionals need to provide reproductive counselling and mental health for prenatal depression should explore feelings about being pregnant and being a mother.

Newborn electroencephalographic correlates of maternal prenatal depressive symptoms

Maternal perinatal depression exerts pervasive effects on the developing brain, as evidenced by electroencephalographic (EEG) patterns that differ between children of women who do and do not meet DSM or ICD diagnostic criteria. However, little research has examined if the same EEG pattern of right-frontal alpha asymmetry exists in newborns and thus originates in utero independent of postnatal influences, and if depressive symptoms are associated with this neural signature. Utilizing 125-lead EEG (n=18), this study considered clinician-rated maternal prenatal depressive symptoms in relation to newborn EEG. Maternal depressive symptomatology was associated with greater relative right-frontal alpha asymmetry during quiet sleep. These results suggest that even subclinical levels of maternal depression may influence infant brain development, and further support the role of the prenatal environment in shaping children's future neurobehavioral trajectories.

Maternal depression during pregnancy is associated with increased birth weight in term infants

Previous research of maternal depression during pregnancy suggests an association with low birth weight in newborns. Review of these studies reveals predominant comorbidity with premature birth. This current study examines antenatal depression and birth weight in term, medically low-risk pregnancies. Maternal physiological and demographic measures were collected as well. In total, 227 pregnant women were recruited to participate in four experimental protocols at Columbia University Medical Center. Results indicate that depressed pregnant women who carry to term had significantly higher heart rates, lower heart rate variability, and gave birth to heavier babies than those of pregnant women who were not depressed. Low income participants had significantly higher levels of depression, as well as significantly higher heart rates and lower heart rate variability, than those in higher income groups. In full-term infants, maternal prenatal depression appears to promote higher birth weight, with elevated maternal heart rate as a likely mediating mechanism.

Maternal prenatal depression is associated with decreased placental expression of the imprinted gene PEG3

BACKGROUND

Maternal prenatal stress during pregnancy is associated with fetal growth restriction and adverse neurodevelopmental outcomes, which may be mediated by impaired placental function. Imprinted genes control fetal growth, placental development, adult behaviour (including maternal behaviour) and placental lactogen production. This study examined whether maternal prenatal depression was associated with aberrant placental expression of the imprinted genes paternally expressed gene 3 (PEG3), paternally expressed gene 10 (PEG10), pleckstrin homology-like domain family a member 2 (PHLDA2) and cyclin-dependent kinase inhibitor 1C (CDKN1C), and resulting impaired placental human placental lactogen (hPL) expression.

METHOD

A diagnosis of depression during pregnancy was recorded from Manchester cohort participants' medical notes (n = 75). Queen Charlotte's (n = 40) and My Baby and Me study (MBAM) (n = 81) cohort participants completed the Edinburgh Postnatal Depression Scale self-rating psychometric questionnaire. Villous trophoblast tissue samples were analysed for gene expression.

RESULTS

In a pilot study, diagnosed depression during pregnancy was associated with a significant reduction in placental PEG3 expression (41%, p = 0.02). In two further independent cohorts, the Queen Charlotte's and MBAM cohorts, placental PEG3 expression was also inversely associated with maternal depression scores, an association that was significant in male but not female placentas. Finally, hPL expression was significantly decreased in women with clinically diagnosed depression (44%, p < 0.05) and in those with high depression scores (31% and 21%, respectively).

CONCLUSIONS

This study provides the first evidence that maternal prenatal depression is associated with changes in the placental expression of PEG3, co-incident with decreased expression of hPL. This aberrant placental gene expression could provide a possible mechanistic explanation for the co-occurrence of maternal depression, fetal growth restriction, impaired maternal behaviour and poorer offspring outcomes.

Prenatal Depression Screening by Certified Nurse-Midwives, Oregon

INTRODUCTION

About 18% of pregnant women have major or minor depression during pregnancy, but many are neither screened nor treated. Lack of treatment can have serious adverse consequences for the woman and her child. Since 2002, the American College of Nurse-Midwives has advised midwives to integrate prevention, universal screening, treatment, and/or referral for depression into the care they provide. The American College of Obstetricians and Gynecologists' 2015 guidelines recommend screening at least once in the perinatal period using a standardized, validated tool. A consensus has not been reached by professional organizations about the specifics of whether and when to screen for prenatal depression. The objective of this study is to understand the prenatal screening practices of midwives who practice in Oregon.

METHODS

We surveyed all 162 Oregon-licensed certified nurse-midwives (CNMs). The survey asked about practice characteristics, demographics, screening, and perceived barriers to screening. The survey was administered electronically from October through December 2014.

RESULTS

The response rate was 37%. Among the 53 CNM respondents who had provided prenatal care in the previous year, 50 (94%) reported screening for prenatal depression, and 38 (72%) reported the use of a standardized screening tool on more than 90% of prenatal patients. Thirty-five (66%) CNMs reported using the Edinburgh Postnatal Depression Scale. More than 60% of respondents indicated that availability of mental health services and insurance constraints were barriers to screening.

DISCUSSION

We explored prenatal depression screening practices of CNMs. Most Oregon CNMs use a standardized screening tool. We suggest 2 strategies to overcome barriers to screening: incorporation of a standardized screening tool into electronic medical records and negotiation with insurance companies. More research is needed to clarify when and how often pregnant women should be screened for depression and how to increase the number of women who receive treatment.

A Prospective Investigation of Prenatal Mood and Childbirth Perceptions in an Ethnically Diverse, Low-Income Sample

INTRODUCTION

Few studies have examined prenatal mood as a means to identify women at risk for negative childbirth experiences. We explore associations between prenatal mood and birth perceptions in a socioeconomically diverse, American sample.

METHODS

We conducted a prospective study of 136 predominantly low-income and ethnic minority women of mixed parity. Prenatal measures of perceived stress, pregnancy-related anxiety, and depressive symptoms were used to predict maternal perceptions of birth experiences 1 month postpartum, using the childbirth experience questionnaire (CEQ; 1).

RESULTS

After adjusting for sociodemographic variables and mode of delivery, higher third-trimester stress predicted worse CEQ total scores. This association was predominantly explained by two CEQ domains: own capacity (e.g., feelings of control and capability), and perceived safety. Pregnancy-related anxiety and depressive symptoms correlated with perceived stress, though neither independently predicted birth experience. An unplanned cesarean delivery was associated with a worse CEQ total score. Vaginal delivery predicted greater perceived safety. Altogether, sociodemographic covariates, mode of delivery, and prenatal mood accounted for 35 percent of the variance in birth experience (p < 0.001).

DISCUSSION

Our finding that prenatal stress explains a significant and likely clinically meaningful proportion of the variance in birth experience suggests that women perceive and recall their birth experiences through a lens that is partially determined by preexisting personal circumstances and emotional reserves. Since childbirth perceptions have implications for maternal and child health, patient satisfaction, and health care expenditures, these findings warrant consideration of prenatal stress screening to target intervention for women at risk for negative birth experiences.

Depressive Symptoms in Pregnancy: The Influence of Social, Psychological and Obstetric Aspects

Purpose To assess the prevalence of depressive symptoms and their association with social, psychological, behavioral and obstetric characteristics in pregnant women. Methods This is a cross-sectional study. The sample consisted of 375 pregnant women who attended prenatal clinics in two public maternity hospitals located in the city of Goiania, Brazil. To testify the depressive symptoms, we used the Hospital Anxiety and Depression Scale (HADS). A descriptive statistical analysis was performed using programs such as CDC EPI-INFO™, version 7.1.5, and Statistical Package for Social Sciences (IBM SPSS), version 21.0. Results the patients had probable depressive symptoms (15.47%) and possible depressive symptoms (25.33%). The bivariate analysis showed a significant association among "depressive symptoms" and the following variables: "single or divorced" (prevalence ratio, PR = 2.08; 95% confidence interval, CI = 1.26 to 3.44); "physical activity during pregnancy" (PR = 3.96; 95%CI = 1.28 to 12.31); exposure to "psychological/emotional" violence (PR = 4.74; 95%CI = 2.94 to 7.64); "prior mental problem" (PR = 2.66; 95%CI =1.49 to 4.73) and "obstetric complications during pregnancy" (PR = 2.53; 95%CI = 1.55 to 4.13). The multivariate analysis confirmed the association of these depressive symptoms with the variables "suffered psychological/emotional violence" (odds ratio, OR = 5.821; 95%CI = 2.939 to 11.528); "physical activity during pregnancy" (OR = 3.885; 95%CI = 1.060 to 14.231); "obstetric complications during pregnancy" (OR = 2.442; 95%CI = 1.233 to 4.834) and "single or divorced" (OR = 2.943; 95%CI = 1.326 to 6.533). Conclusions the prevalence of depressive symptoms among pregnant women is of 15.47%, and emotional violence is the main factor associated with gestational depression.

Maternal Prenatal Mental Health and Placental 11β-HSD2 Gene Expression: Initial Findings from the Mercy Pregnancy and Emotional Wellbeing Study

High intrauterine cortisol exposure can inhibit fetal growth and have programming effects for the child's subsequent stress reactivity. Placental 11beta-hydroxysteroid dehydrogenase (11β-HSD2) limits the amount of maternal cortisol transferred to the fetus. However, the relationship between maternal psychopathology and 11β-HSD2 remains poorly defined. This study examined the effect of maternal depressive disorder, antidepressant use and symptoms of depression and anxiety in pregnancy on placental 11β-HSD2 gene (HSD11B2) expression. Drawing on data from the Mercy Pregnancy and Emotional Wellbeing Study, placental HSD11B2 expression was compared among 33 pregnant women, who were selected based on membership of three groups; depressed (untreated), taking antidepressants and controls. Furthermore, associations between placental HSD11B2 and scores on the State-Trait Anxiety Inventory (STAI) and Edinburgh Postnatal Depression Scale (EPDS) during 12-18 and 28-34 weeks gestation were examined. Findings revealed negative correlations between HSD11B2 and both the EPDS and STAI (r = -0.11 to -0.28), with associations being particularly prominent during late gestation. Depressed and antidepressant exposed groups also displayed markedly lower placental HSD11B2 expression levels than controls. These findings suggest that maternal depression and anxiety may impact on fetal programming by down-regulating HSD11B2, and antidepressant treatment alone is unlikely to protect against this effect.

Untreated depression during pregnancy: Short- and long-term effects in offspring. A systematic review

Aim of this systematic review is to assess short- and long-lasting effects of antenatal exposure to untreated maternal depressive symptoms. Pertinent articles were identified through combined searches of Science.gov, Cochrane library, and PubMed databases (through August 2015). Forty-three, selected articles revealed that untreated gestational depression and even depressive symptoms during pregnancy may have untoward effects on the developing fetus (hyperactivity, irregular fetal heart rate), newborns (increased cortisol and norepinephrine levels, decreased dopamine levels, altered EEG patterns, reduced vagal tone, stress/depressive-like behaviors, and increased rates of premature deaths and neonatal intensive care unit admission), and children (increased salivary cortisol levels, internalizing and externalizing problems, and central adiposity). During adolescence, an independent association exists between maternal antenatal mood symptoms and a slight increase in criminal behaviors. In contrast, the relationship between gestational depression and increased risks of prematurity and low birth weight remains controversial. Given this background, when making clinical decisions, clinicians should weigh the growing evidences suggesting the detrimental and prolonged effects in offspring of untreated antenatal depression and depressive symptoms during pregnancy against the known and emerging concerns associated with in utero exposure to antidepressants.

Pregnancy Hyperglycaemia and Risk of Prenatal and Postpartum Depressive Symptoms

BACKGROUND

Glucose dysregulation in pregnancy may affect maternal depressive symptoms during the prenatal and postpartum periods via both physiologic and psychological pathways.

METHODS

During mid-pregnancy, a combination of 50-g 1-h non-fasting glucose challenge test (GCT) and 100-g 3-h fasting oral glucose tolerance test was used to determine pregnancy glycaemic status among women participating in Project Viva: normal glucose tolerance (NGT), isolated hyperglycaemia (IHG), impaired glucose tolerance (IGT) and gestational diabetes mellitus (GDM). Using the Edinburgh Postnatal Depression Scale (EPDS), we assessed depressive symptoms at mid-pregnancy and again at 6 months postpartum. We used logistic regression, adjusted for sociodemographic, anthropometric and lifestyle factors, to estimate the odds of elevated prenatal and postpartum depressive symptoms (EPDS ≥ 13 on 0-30 scale) in relation to GCT glucose levels and GDM status in separate models.

RESULTS

A total of 9.6% of women showed prenatal and 8.4% postpartum depressive symptoms. Women with higher GCT glucose levels were at greater odds of elevated prenatal depressive symptoms [multivariable-adjusted odds ratio (OR) per standard deviation (SD) increase in glucose levels (27 mg/dL): 1.25; 95%: 1.07, 1.48]. Compared with NGT women, the association appeared stronger among women with IHG [OR: 1.80; 95% confidence interval (CI): 1.08, 3.00] than among those with GDM (OR: 1.45; 95% CI: 0.72, 2.91) or IGT (OR: 1.43; 95% CI: 0.59, 3.46). Neither glucose levels assessed from the GCT nor pregnancy glycaemic status were significantly associated with elevated postpartum depressive symptoms.

CONCLUSION

Pregnancy hyperglycaemia was cross-sectionally associated with higher risk of prenatal depressive symptoms, but not with postpartum depressive symptoms.

Effects of prenatal factors and temperament on infant cortisol regulation in low-income Mexican American families

Prenatal psychosocial exposures can significantly affect infant health and development. Infants with higher temperamental negativity are theorized to be more susceptible to environmental exposures. We evaluated the interaction of prenatal maternal exposures and infant temperamental negativity to predict infant cortisol response to mildly challenging mother-infant interaction tasks. Participants included 322 Mexican American mother-infant dyads (mother age 18-42; 82% Spanish-speaking; modal family income $10,000-$15,000). Mothers reported depressive symptoms and social support prenatally and infant temperamental negativity at 6 weeks postpartum. Salivary cortisol was collected from infants before and after mother-infant interaction tasks at 12 weeks. Higher prenatal maternal depressive symptoms and lower social support predicted higher cortisol among infants with higher temperamental negativity. Higher infant temperamental negativity predicted an increase in maternal distress and a decrease in social support from prenatal to 12 weeks postpartum. Interactive influences of maternal social-contextual factors and infant temperament may influence the development of infant neurobiological regulation and promote or strain maternal and infant adaptation over time.
