Antenatal depression: Prevalence and risk factor patterns across the gestational period

Exploring prenatal depression and postpartum depression: Findings from a prospective cohort study at University Hospital Obstetrics in Damascus

The perinatal period is crucial for both mother and newborn, and mental health, including prenatal and postpartum depression (PPD), is a significant aspect. Screening for these disorders allows for early treatment and helps prevent risks to both mother and child. This prospective cohort study was carried out at University Hospital Obstetrics in Damascus City. The first phase was during the third trimester of pregnancy and the second phase involved a follow-up assessment after 6 weeks of delivery. The Arabic-validated version of the Edinburgh Postnatal Depression Scale questionnaire (EPDS) was used. A cutoff of 13 or higher was used to determine the presence of probable depression in both assessments. Of 347 pregnant women, 38.6% had prenatal depression (PND). 295 patients have achieved the second assessment, of which 30.2% had PPD. Furthermore, 42.6% who had PND developed PPD on follow-up. Binary logistic regression indicated that PND was predicted by non-Syrian nationality, paternal absence, poor financial status, number of previous pregnancies, and a history of depression independent of pregnancy. PPD was predicted by a history of PPD, and work status. Findings underscore potential value of early screening for depressive symptoms as a predictive measure. It is recommended that women with a history of depression receive heightened attention and care, irrespective of the timing of their depressive episodes.

Prevalence of Perinatal Anxiety and Related Disorders in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis

Importance

Anxiety disorders are associated with poor maternal and neonatal outcomes. Women in low- and middle-income countries (LMICs) are thought to be disproportionally burdened by these disorders, yet their prevalence is unclear.

Objective

To conduct a systematic review and meta-analysis to determine the prevalence of 6 anxiety and related disorders among perinatal women in LMICs.

Data Sources

Embase, MEDLINE, PsycINFO, Cochrane Library, CINAHL, and Web of Science databases were searched from inception until September 7, 2023.

Study Selection

Studies conducted in World Bank-defined LMICs and reporting prevalence of generalized anxiety disorder, obsessive-compulsive disorder, social anxiety disorder, posttraumatic stress disorder, panic disorder, or adjustment disorder during the perinatal period (conception to 12 months post partum) using a validated method were included.

Data Extraction and Synthesis

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. Study eligibility, extracted data, and risk of bias of included studies were assessed by 2 independent reviewers. Random-effects meta-analysis was used to estimate pooled point prevalence. Subgroup analyses were performed by specific anxiety disorder.

Main Outcomes and Measures

Main outcomes were prevalence estimates of each anxiety disorder, measured as percentage point estimates and corresponding 95% CIs.

Results

At total of 10 617 studies were identified, 203 of which met the inclusion criteria and reported the outcomes of 212 318 women from 33 LMICs. Generalized anxiety disorder was the most reported (184 studies [90.6%]) and most prevalent disorder at 22.2% (95% CI, 19.4%-25.0%; n = 173 553). Posttraumatic stress disorder was the second most prevalent (8.3%; 95% CI, 5.0%-12.2%; 33 studies; n = 22 452). Adjustment disorder was least prevalent (2.9%; 95% CI, 0.0%-14.1%; 2 studies; n = 475). The prevalence of generalized anxiety varied by country income status, with the highest prevalence among lower-middle-income countries (27.6%; 95% CI, 21.6%-33.9%; 59 studies; n = 25 109), followed by low-income (24.0%; 95% CI, 15.3%-33.8%; 11 studies; n = 4961) and upper-middle-income (19.1%; 95% CI, 16.0%-22.4%; 110 studies; n = 138 496) countries.

Conclusions and Relevance

These findings suggest that 1 in 5 women living in LMICs experience anxiety disorders during pregnancy and post partum. Targeted action is needed to reduce this high burden.

Prevalence and Risk Factors of Depression and Anxiety among Women in the Last Trimester of Pregnancy: A Cross-Sectional Study

Pregnancy represents a psychologically and emotionally vulnerable period, and research indicates that pregnant women have a higher prevalence of symptoms of anxiety and depression, debunking the myth that hormonal changes associated with pregnancy protect the mother. In recent years, several researchers have focused on the study of prenatal anxiety/depression-emotional disorders manifested by mood lability and low interest in activities-with a high prevalence. The main objective of this research was to conduct an antenatal screening in a cohort of pregnant women hospitalized for delivery in order to assess the prevalence of anxiety and depression. The secondary objective was to identify the risk factors associated with depression and anxiety in women in the third trimester of pregnancy. We carried out a prospective study in which we evaluated 215 pregnant women in the third trimester of pregnancy hospitalized for childbirth at the Obstetrics and Gynecology Clinic of the Târgu-Mureș County Clinical Hospital. The research was carried out between December 2019 and December 2021. The results showed that age and the environment of origin are the strongest predictors of mental health during pregnancy (OR = 0.904, 95%CI: 0.826-0.991; p = 0.029). For women from urban areas, there is an increased probability of falling at a higher level on the dependent variable (moderate depression) (OR = 2.454, 95%CI: 1.086-5.545; p = 0.032). In terms of health behaviors, none of the variables were statistically significant predictors of the outcome variable. The study highlights the importance of monitoring mental health during pregnancy and identifying relevant risk factors to provide appropriate care to pregnant women and the need for interventions to support the mental health of pregnant women. Especially in Romania, where there is no antenatal or postnatal screening for depression or other mental health conditions, these results could be used to encourage the implementation of such screening programs and appropriate interventions.

Prevalence of perinatal anxiety in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Perinatal anxiety is associated with adverse outcomes for women and their infants. Women in low- and middle-income countries (LMIC) may be at higher risk of perinatal anxiety. We aimed to systematically review and synthesise the evidence on prevalence of perinatal anxiety in LMIC.

METHOD

We searched MEDLINE, Embase, PscyhINFO, Global Health and Web of Science to identify studies assessing prevalence of perinatal anxiety in LMIC. Studies published since January 2016 were included. Screening and data extraction was conducted independently by two reviewers. Pooled prevalence estimates were calculated using random-effect meta-analyses and sources of heterogeneity explored through subgroup analyses and meta-regression.

RESULTS

We screened 9494 titles and abstracts, reviewed 700 full-texts and included 54 studies in the systematic review and meta-analysis. The pooled prevalence of self-reported anxiety symptoms was 29.2% (95%CI 24.5-34.2; I² 98.7%; 36 studies; n = 28,755) antenatally and 24.4% (95%CI 16.2-33.7; I² 98.5%; 15 studies; n = 6370) postnatally. The prevalence of clinically-diagnosed anxiety disorder was 8.1% (95%CI 4.4-12.8; I² 88.1% 5 studies; n = 1659) antenatally and 16.0% (95% CI 13.5-18.9; n = 113) postnatally.

LIMITATIONS

Our search was limited to studies published since January 2016 in order to update a previous review on this topic.

CONCLUSION

Perinatal anxiety represents a significant burden in LMIC, with one in four women experiencing symptoms during pregnancy or postpartum. Research remains lacking in a significant proportion of LMIC, particularly in the lowest income countries. Further research should guide application of screening tools in clinical settings to identify women with anxiety disorders in order to provide appropriate treatment.

Anxiety, depression and marital satisfaction in women with hyperemesis gravidarum: A comparative cross-sectional study in Hospital Tengku Ampuan Rahimah, Klang, Malaysia

INTRODUCTION

Hyperemesis Gravidarum (HG) is a severe form of vomiting that occurs among pregnant mothers. Due to the nature of HG, pregnant mothers may feel fatigued and burdened by it and questions have been raised about the emergence of psychiatric illness during this period of vulnerability.

METHODS

A comparative cross-sectional study using Hospital Anxiety and Depression Scale (HADS), M.I.N.I (MINI International Neuropsychiatric Interview) and ENRICH- EMS (Evaluation and Nurturing Relationship Issues, Communication and Happiness - Marital Satisfaction Scale) were performed in a group of 112 pregnant women.

RESULTS

There were no differences in the prevalence rate of any anxiety disorder among the patient with HG vs comparative group (9% vs 3%, P > 0.05) and depressive disorder in women with HG vs comparative group (16% vs 8%, P > 0.05) respectively. There were associations between HG and gravida, past history of miscarriage, and gestational diabetes (P < 0.05). After adjustment, only past history of gestational diabetes was associated with HG as a protective factor (AOR 0.034 95% CI 0.002-0.181; P = 0.0014). We found that women in the HG group tended to score statistically significantly higher than the comparison group for depressive symptoms in the HADS Depression subscale (P = 0.041).

DISCUSSION

We found no convincing association between HG and anxiety disorder, depressive disorder, and marital satisfaction, but women with HG statistically significantly reported more depressive symptoms than women who were not diagnosed with HG. Psychiatric evaluation should be considered for women with HG.

Does antenatal depression predict post-partum depression and obstetric complications? Results from a longitudinal, long-term, real-world study

BACKGROUND

Main aims of the present paper are to: (1) assess the prevalence of antenatal depression (AD) and identify its predictors; (2) analyse the impact of AD on obstetric outcomes and on the incidence of post-partum depression.

METHODS

All pregnant women referring to the Gynecology and Obstetrics inpatients unit of the University of Campania "Luigi Vanvitelli" were invited to participate. Upon acceptance, women completed the Italian version of the Edinburgh Postnatal Depression Scale and an ad-hoc questionnaire on the women's sociodemographic, gynecological and peripartum characteristics as well as their psychiatric history. Women were assessed at each trimester of pregnancy, immediately after the childbirth and after one, three, 6 and 11 months.

RESULTS

268 pregnant women were recruited, with a mean of 32.2 (±5.81) years. Ninety-seven women (36.2%) reported the presence of depressive symptoms during pregnancy. Predictors of AD were personal history of depression, a family history for depressive disorders and problematic relationships with the partner. The presence of AD was associated to a reduced gestational age at the time of delivery, a lower APGAR score at 1 and 5 min, labor induction and admission of the new-born into neonatal intensive care unit. Mothers with antenatal depression are less likely to natural breastfeed. Lastly, antenatal depression was a risk factor for higher EPDS scores at follow-ups.

CONCLUSIONS

Our results support the idea that women should be screened during pregnancy and post-partum for the presence of depressive and anxiety symptoms. Health professionals should be adequately trained to detect psychiatric symptoms during pregnancy.

The Role of Maternal Perceived Social Support on the Relation Between Prenatal Depressive Symptoms and Labor Experience

Abstract. Background: Depression during pregnancy is a severe risk factor for negative outcomes in women and children. In particular, prenatal symptoms of depression are linked to a more complicated labor experience, characterized by more painful labor and more frequent recourse to epidural analgesia and/or oxytocin. Although this link is evident, less is known about possible mediators of this relationship. Aims: This study investigated the mediating role of perceived maternal social support on the relationship between prenatal maternal depression and labor experience. Methods: Participants were 152 Italian nulliparous women ( Mage = 31.68 years, SD = 4.94). Data were collected at two different times: T1 (at week 30–33 of gestation) women completed the Beck Depression Inventory and the Maternal Social Support Scale; T2 (at childbirth) clinical data regarding labor was registered from hospital records (duration of labor in hours and administration of oxytocin and epidural analgesia in hours). Results: The Structural Equation Modeling showed that prenatal symptoms of depression are linked to a more complicated labor experience (β = .31, p < .001). However, the quality of the maternal social support can mediate this relationship (indirect effect: β = .17, p < .000). Limitations: The complexity of the proposed model, the characteristics of the sample, the variables investigated, and the questionnaires used are discussed. Conclusion: The perception of having a good social network is an important predictor of women’s health in the transition to motherhood, decreasing the negative effect of maternal prenatal depressive symptoms on the quality of women’s labor experience.

Changing patterns of prenatal depression and anxiety status in different trimesters and modified form of Zung scales for pregnant women

BACKGROUND

We described the changing patterns of depression and anxiety status in different trimesters among Chinese pregnant women, and identified the modified form of SDS/SAS for pregnant women and assessed its reliability and validity.

METHODS

Changing patterns of depression/ anxiety status in different trimesters were described. The modified form of SDS/SAS was identified for pregnant women. Cohen's Kappa to measure agreement with SDS/SAS, and the ROC analysis was performed to assess its validity.

RESULTS

The SDS score in 1st trimester was higher than 2nd and 3rd trimester; there was no significant difference between SDS score in 2nd and 3rd trimester. Modified form of SDS evaluated the depression; the areas under the curve (AUC) in testing group were up to 0.988, 0.989 and 0.992 for 1st, 2nd and 3rd trimester, respectively. Modified form of SAS evaluated the anxiety, the AUC in testing group were up to 0.987, 0.985, 0.987 for 1st, 2nd and 3rd trimester, respectively.

CONCLUSION

Pregnant women had higher severity of depression and anxiety status in 1st trimester than that in 2nd and 3rd trimester. The modified form of SDS/SAS may be more brief and suitable to assess the depression and anxiety status in pregnant women.KEY POINTSPregnant women had a higher severity of depression and anxiety status in the 1st trimester than that in the 2nd and 3rd trimester.The present study suggests that prenatal depression and anxiety status are prevalent in Chinese pregnant women.Prevention or treatments focus on high-score items of SDS and SAS would be beneficial for rectifying prenatal depression and anxiety.

Trajectories of perinatal depressive symptoms in the context of the COVID-19 pandemic

This study sought to advance understanding of the potential long‐term consequences of the COVID‐19 pandemic for child development by characterizing trajectories of maternal perinatal depression, a common and significant risk factor for adverse child outcomes. Data came from 393 women (86% White, 8% Latina; mean age = 33.51 years) recruited during pregnancy (n = 247; mean gestational age = 22.94 weeks) or during the first year postpartum (n = 146; mean child age = 4.50 months; 55% female). Rates of depression appear elevated, relative to published reports and to a pre‐pandemic comparison group (N = 155). This study also provides evidence for subgroups of individuals who differ in their depressive symptom trajectories over the perinatal period. Subgroup membership was related to differences in maternal social support, but not to child birth outcomes.

Risk factors for antenatal depression: A review

Depression is the most prevalent mental disorder in pregnancy, and yet it is less studied than postpartum depression despite the consequences it may have on both the pregnant woman and her offspring. Therefore, it would be important to know which risk factors may favour the appearance of antenatal depression in order to carry out appropriate prevention interventions. The aim of the present review was to identify the main risk factors of antenatal depression. We searched in databases PubMed and PsycINFO for articles published about the factors associated with antenatal depression from January 2010 through December 2020. The literature review identified three main groups of antenatal depression risk factors: sociodemographic, obstetric, and psychological. First, among the sociodemographic variables, the low level of studies and the economic income clearly stood out from the rest. Then, not having planned the pregnancy was the main obstetric variable, and finally, the main psychological risk factors were having a history of psychological disorders and/or depression as well as presenting anxiety, stress, and/or low social support during pregnancy. This review shows that the antenatal depression is affected by multiple factors. Most can be identified at the beginning of the pregnancy, and some are risk factors potentially modifiable through appropriate interventions, such as psychological factors. For this reason, it is important to carry out a good screening for depression during pregnancy and consequently, be able to prevent its appearance or treat it if necessary.

A Primer on DNA Methylation and Its Potential to Impact Maternal Depression Risk and Assessment During Pregnancy and the Postpartum

Depression onset during and after pregnancy is prevalent and associated with significant implications for maternal, child, and family health. Although environmental risk factors important to the expression of pregnancy-related depression are well known, knowledge of the genetic underpinning is limited. Given the joint contribution of environmental and genetic factors to depression risk liability, DNA methylation presents itself as an ideal biomarker to investigate basic mechanisms and opportunities for translational research to care for pregnancy-related depression health outcomes. This article is an introduction to DNA methylation and its potential to serve as a marker of depression risk during pregnancy and the postpartum. This commentary discusses current clinical uses of DNA methylation-based testing and how it may be applied to perinatal depression clinical care and management.

The hypothalamic-pituitary-adrenal axis in the perinatal period: Its relationship with major depressive disorder and early life adversity

Objectives: Effects of major depressive disorder and early life adversity (ELA) on the maternal HPA axis in the perinatal period were examined.Methods: Four groups of women (n = 127) were recruited, with the perinatal groups being compared during pregnancy (Preg) and at two months postpartum (PP) - [1] Depressed during pregnancy (Depressed-Preg/PP), [2] Prior history of depression but euthymic during pregnancy (History-Preg/PP), [3] Healthy pregnant women (Control-Preg/PP), and [4] Healthy non-pregnant women (Non-pregnant Control). Serial saliva samples were collected over the course of a day and waking and evening cortisol, total cortisol output and the cortisol awakening response were examined.Results: There were no HPA axis differences among the three groups during pregnancy. A history of ELA, regardless of comorbid depression, was associated with higher evening cortisol levels during pregnancy (p = 0.015). Women in the Depressed-PP group had had higher evening cortisol levels compared to the History-PP group (p < 0.017).Conclusions: Evening cortisol measures are a potential marker for both ELA and depression, with higher levels during pregnancy being associated with ELA and higher levels postpartum being associated with antenatal depression.

The efficacy of cognitive behavioral therapy for the treatment of antenatal depression: A systematic review

BACKGROUND

Antenatal depression affects 7-20% of pregnant women globally yet less than a fifth of such women receive adequate treatment. Cognitive behavioral therapy (CBT) is known to be effective in the treatment of depression. However, the research is more limited with regard to the antenatal period suggesting a need for clearer evidence within this field.

OBJECTIVE

To determine if CBT is effective in the treatment of antenatal depression.

METHODS

Medline, Embase, PsychINFO, CINAHL and CENTRAL were searched for studies that quantified the effectiveness of CBT in women with a confirmed diagnosis of antenatal depression. Randomised controlled trials that measured the effectiveness of CBT delivered during the antenatal period, compared to another intervention or usual care, measured using a validated depression score pre and post intervention were included.

RESULTS

Five RCTs were eligible for inclusion, all of which found a significant decrease in depression scores following CBT interventions, greater than that observed in control groups. Improvements in depressive scores were maintained long-term for participants who received CBT. Participant satisfaction with the interventions received was high.

LIMITATIONS

Studies included displayed major performance biases, and language bias is present due to exclusion of an Iranian paper.

CONCLUSION

CBT, tailored to pregnant women, is effective in the treatment of antenatal depression, with little difference in efficacy between CBT sub-types. Further large-scale RCTs are needed to confirm these hypotheses and determine the most cost-effective way of delivering CBT to pregnant women. There is also need for a specific, validated tool for assessing antenatal depression.

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.

Testing the Multiple Pathways of Residential Greenness to Pregnancy Outcomes Model in a Sample of Pregnant Women in the Metropolitan Area of Donostia-San Sebastián

Residential greenness may positively impact diverse human health indicators through the reduction of air pollution, the improvement of psychological health, and the promotion of physical activity. Previous studies indicate a weak but positive association with pregnancy outcomes. Our aim was to test the multiple pathways from residential greenness to pregnancy outcomes model, using residential NO₂ concentrations, psychological health, and moderate-to-vigorous physical activity (MVPA) during the first trimester of pregnancy, in a sample of 440 pregnant women residing in Donostia, Spain. Three metrics of residential greenness were calculated around each participant’s home address: normalized difference vegetation index (NDVI) within 300 m, and green space (>5000 m²) availability within 300 and 500 m. Residential NO₂ concentrations, psychological health, and MVPA were explored as mediators of the associations between these metrics and the following pregnancy outcomes: birth weight (BW), low birth weight (LBW), prematurity, small for gestational age (SGA), and large for gestational age (LGA). Educational attainment, parity, and body mass index (BMI) were treated as covariates. Counterfactual mediation analyses showed very low to null statistical support for an association between any of the greenspace metrics and pregnancy outcomes in the full sample. Green space availability (300 m) was associated with lower BW and showed a marginal protective effect against LGA.

Prevalence and associated risk factors of antenatal depression among women attending antenatal clinics in primary health care centers in the Ministry of Health in Al-Ahsa City, Saudi Arabia

Objectives:

This study was aimed to measure the prevalence and associated risk factors of antenatal depression (AD) among women attending antenatal clinics at primary care centers in the Ministry of Health in Al-Ahsa, Saudi Arabia.

Materials and Methods:

A cross-sectional study was conducted on 357 pregnant women attending antenatal clinics at primary care centers, Ministry of Health, Al-Ahsa, Saudi Arabia between April 1, 2018 and July 1, 2019. A self-administered questionnaire was used for collection of information including questions relevant to sociodemographic variables and a screening tool Edinburgh Postnatal Depression Scale (EPDS) was used to assess the probable depression.

Results:

The prevalence of AD among pregnant women in Al-Ahsa is 31.9%. We found a significant association (P < 0.005) between AD and factors such as difficulty in sleeping, having a smoker husband, having one previous pregnancy, and having postabortion psychological complications.

Conclusion:

It was observed that depression prevails among pregnant ladies in Al-Ahsa city. Hence, in the present study, we tried to rule out the factors that led to depression in pregnant ladies during our antenatal care. In addition, we found that there is a need to train the physicians for asking questions (only two simple PHQ-2 questions) for the screening of depression during antenatal care visite.

Association between social and family support and antenatal depression: a hospital-based study in Chengdu, China

BACKGROUND

Antenatal depression (AD) is considered as one of the major health burdens and has adverse effects on the outcome of expectant mothers and newborns. The present study aims to investigate the prevalence of antenatal depression (AD), and to explore the potential risk factors of AD among pregnant women in Chengdu, including personal background, related social factors, family factors and cognitive factors.

METHODS

The prospective nested case-control study included pregnant women who were in their second pregnancy and attended prenatal care at three tertiary hospitals and one regional hospital in Chengdu, China, between March 2015 and May 2016. Self-designed questionnaires were given to participants in their second and third trimesters to collect information on clinical and demographic characteristics, and a modified edition of Edinburgh Postnatal Depression Scale (EPDS) were used to measure AD. The logistic regression was applicated in analyses.

RESULTS

A total of 996 pregnant women were included in analysis. Ninety-three women suffered from AD symptoms only in their second trimester, 96 only in their third trimester, and 107 displayed persistent depression in both trimesters. In the univariate analyses, age and marital relationships were linked with AD occurrence in both second and third trimester. In addition, increasing age, full-time job, higher education level, and no gender preference of spouse were associated with reduced persistent depression. Multivariate analysis showed that gender preference and marital relationship were the potential risk factors of persistent depression.

CONCLUSIONS

Age, marital relationship relationships, with parents-in-law, the negative recognition of this pregnancy and husband's gender preference were found as risk factors of AD occurrence in some specific trimester. Gender preference of husbands and marital relationships were independently associated with persistent depression. These findings suggest that stronger family support can help improve mental health of pregnant women.

DNA methylation studies of depression with onset in the peripartum: A critical systematic review

OBJECTIVE

Major depression with peripartum onset (MDP) has been associated with multiple adverse offspring health outcomes. The biological mechanisms underlying this relationship remain unclear, but DNA methylation (DNAm) represents a plausible mechanism for mediating MDP exposures and changes in offspring development, behavior, and health. Advances in DNAm research necessitate reevaluating the MDP-DNAm literature to determine how well past studies conform with current best practices.

METHOD

Five databases were searched to identify studies of prenatal-onset MDP and DNAm. Quality scores were assigned to each article independently by two raters using a novel scale specific for MDP-DNAm research.

RESULTS

Nineteen studies met inclusion criteria. Quality scores ranged from 10 to 17 out of 24 points (M = 12.8; SD = 1.9), with higher scores indicating increased study rigor. Poor covariate reporting was the most significant contributor to lower scores.

CONCLUSION

No longitudinal MDP-DNAm studies exist. Earlier MDP-DNAm studies should be interpreted with caution, and future research must commit to sharing methodology and data to facilitate cross-study comparisons and maximize dataset utility.

Implications of the clinical gestational diagnosis of ZIKV infection in the manifestation of symptoms of postpartum depression: a case-control study

BACKGROUND

Traumatic events can trigger postpartum depression. Pregnant women in Brazil today are facing an extremely stressful experience. Thus, the objective here was to analyze the prevalence of symptoms of depression in the immediate postpartum period (IPPD) and associate these symptoms with previous stressful, social, psychological, behavioral, obstetrical, clinical, violent and infectious events, particularly exposure to Zika virus (ZIKV) infection during pregnancy.

METHODS

This was a case-control study. The sample comprised 213 puerperal women treated in the maternity ward of a public reference hospital in the Araguaia River Valley of Mato Grosso and Goiás, Brazil. Severe IPPD symptoms were confirmed based on the Edinburgh Postnatal Depression Scale (EPDS). A descriptive statistical analysis was carried out using the Epi Info™ version 7.1.5 suite of software tools and the Statistical Package for Social Sciences (SPSS) version 21.0.

RESULTS

A bivariate analysis revealed a significant association between "severe symptoms of IPPD" and the following variables: "clinical diagnosis of ZIKV during pregnancy" (OR = 13.36; 95% CI = 5.34-33.39); "was separated or divorced in the last year" (OR = 3.58; 95% CI = 1.42-8.99); "suffered an accident in the last year" (OR = 3.32, 95% CI = 1.12-9.82); "suffered emotional violence during pregnancy" (OR = 3.80; 95% CI = 1.81-7.99); "suffered physical violence during pregnancy" (OR = 11.86; 95% CI = 2.07-67.82); "fear of her partner" (OR = 17.90; 95% CI = 3.44-92.99); "dengue fever during pregnancy" (OR = 7.85; 95% CI: 1.66-37.05), and "has a family member diagnosed with mental illness" (OR = 2.54; 95% CI = 1.09-5.93). The multivariate analysis confirmed the association of severe PPD symptoms only with the variables of "clinical diagnosis of ZIKV during pregnancy" (OR = 19.82; 95% CI: 5.35-73.39) and "was separated or divorced in the last year" (OR = 3.92; 95% IC = 1.12-13.63).

CONCLUSIONS

Clinically diagnosed ZIKV during pregnancy may be one of the main events associated with severe IPPD symptoms, showing an almost 20-fold higher chance of occurrence than other factors.

The dynamic course of peripartum depression across pregnancy and childbirth

OBJECTIVE

Peripartum depression (PPD) pertaining to depression in pregnancy and postpartum is one of the most common complications around childbirth with enduring adverse effects on mother and child health. Although psychiatric symptoms may improve or worsen over time, relatively little is known about the course of PPD symptoms and possible fluctuations.

METHODS

We applied a person-centered approach to examine PPD symptom patterns across pregnancy and childbirth. 824 women were assessed at three time points: first trimester (T1), third trimester (T2), and again at eight weeks (T3) postpartum. We assessed PPD symptoms, maternal mental health history, and childbirth variables.

RESULTS

Growth mixture modeling (GMM) analysis revealed four discrete PPD symptom trajectory classes including chronic PPD (1.1%), delayed (10.2%), recovered (7.2%), and resilient (81.5%). Delivery complications were associated with chronic PPD but also with the recovered PPD trajectory class. History of mental health disorders was associated with chronic PPD and the delayed PPD class.

CONCLUSION

The findings underscore that significant changes in a woman's depression level can occur across pregnancy and childbirth. While a minority of women experience chronic PDD, for others depression symptoms appear to significantly alleviate over time, suggesting a form of recovery. Our findings support a personalized medicine approach based on the woman's symptom trajectory. Future research is warranted to identify the mechanisms underlying modifications in PPD symptoms severity and those implicated in recovery.

Antenatal predictors of incident and persistent postnatal depressive symptoms in rural Ethiopia: a population-based prospective study

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.

Inflammation, depression and cardiovascular disease in women: the role of the immune system across critical reproductive events

Women are at increased risk for developing depression and cardiovascular disease (CVD) across the lifespan and their comorbidity is associated with adverse outcomes that contribute significantly to rates of morbidity and mortality in women worldwide. Immune-system activity has been implicated in the etiology of both depression and CVD, but it is unclear how inflammation contributes to sex differences in this comorbidity. This narrative review provides an updated synthesis of research examining the association of inflammation with depression and CVD, and their comorbidity in women. Recent research provides evidence of pro-inflammatory states and sex differences associated with alterations in the hypothalamic-pituitary-adrenal axis, the renin-angiotensin-aldosterone system and the serotonin/kynurenine pathway, that likely contribute to the development of depression and CVD. Changes to inflammatory cytokines in relation to reproductive periods of hormonal fluctuation (i.e. the menstrual cycle, perinatal period and menopause) are highlighted and provide a greater understanding of the unique vulnerability women experience in developing both depressed mood and adverse cardiovascular events. Inflammatory biomarkers hold substantial promise when combined with a patient's reproductive and mental health history to aid in the prediction, identification and treatment of the women most at risk for CVD and depression. However, more research is needed to improve our understanding of the mechanisms underlying inflammation in relation to their comorbidity, and how these findings can be translated to improve women's health.

Depressive Symptom Prevalence and Predictors in the First Half of Pregnancy

INTRODUCTION

Major depression during the peripartum (MDP) period carries significant public health impact due to the potential adverse effects on maternal, infant, and family outcomes.

METHODS

As part of a larger longitudinal study, this cross-sectional observational study sought to build upon the current literature on the prevalence and predictors of depression in the early second trimester of pregnancy, as related to generally accepted risk factors and other less explored risk factors.

RESULTS

The findings from this study suggest that in this sample of 230 black and white women at ∼14 weeks gestation, ∼19% endorsed depressive symptoms and that the most important predictors of depression in pregnancy were a preconception history of a mental health issue (e.g., lifetime depressive episode) and perceived stress. Other relevant predictors were pregnancy-related anxiety, income, and stressful life events.

CONCLUSION/CLINICAL RELEVANCE

It is important for clinicians not only to screen for MDP during prenatal visits by asking about current depressive, stress, and anxiety symptoms but also to identify patients at risk for MDP by asking simple questions about history of preconception/lifetime episodes of depression and stressful life events. Given the variance accounted for by lifetime depression, additional research into how clinicians may approach this important topic is warranted. For example, checklists given in the waiting room may be less likely to elicit endorsement compared with conversations aimed to normalize the range of depressive histories that may have relevance to obstetric health.

Social capital and antenatal depression among Chinese primiparas: A cross-sectional survey

The aim of this study is to investigate the associations between social capital and antenatal depression among Chinese primiparas. A cross-sectional design was used and a questionnaire survey was conducted with 1471 participants using the intercept method at the provincial hospital in Zhejiang in 2016. Antenatal depression was evaluated using the Edinburgh Postnatal Depression Scale (EPDS) and social capital was assessed by the Chinese version of Social Capital Assessment Questionnaire (C-SCAQ). The prevalence of antenatal depression was assessed among Chinese primiparas in their third trimesters. The antenatal depression prevalence among sub-groups with lower social trust (ST), social reciprocity (SR), social network (SN), and social participation (SP) were significantly higher than those among higher score sub-groups. In the fully adjusted model, primiparas' antenatal depression was significantly associated with ST, SR, SN, and SP. Compared to the structural social capital, the cognitive social capital was a more crucial dimension to the prevalence of antenatal depression. For future community pregnancy health care management programs in China, it might be beneficial to add more social capital related intervention.

Antenatal depressive symptoms and perinatal complications: a prospective study in rural Ethiopia

BACKGROUND

Antenatal depressive symptoms affect around 12.3% of women in in low and middle income countries (LMICs) and data are accumulating about associations with adverse outcomes for mother and child. Studies from rural, low-income country community samples are limited. This paper aims to investigate whether antenatal depressive symptoms predict perinatal complications in a rural Ethiopia setting.

METHODS

A population-based prospective study was conducted in Sodo district, southern Ethiopia. A total of 1240 women recruited in the second and third trimesters of pregnancy were followed up until 4 to 12 weeks postpartum. Antenatal depressive symptoms were assessed using a locally validated version of the Patient Health Questionnaire (PHQ-9) that at a cut-off score of five or more indicates probable depression. Self-report of perinatal complications, categorised as maternal and neonatal were collected by using structured interviewer administered questionnaires at a median of eight weeks post-partum. Multivariate analysis was conducted to examine the association between antenatal depressive symptoms and self-reported perinatal complications.

RESULT

A total of 28.7% of women had antenatal depressive symptoms (PHQ-9 score ≥ 5). Women with antenatal depressive symptoms had more than twice the odds of self-reported complications in pregnancy (OR=2.44, 95% CI: 1.84, 3.23), labour (OR= 1.84 95% CI: 1.34, 2.53) and the postpartum period (OR=1.70, 95% CI: 1.23, 2.35) compared to women without these symptoms. There was no association between antenatal depressive symptoms and pregnancy loss or neonatal death.

CONCLUSION

Antenatal depressive symptoms are associated prospectively with self-reports of perinatal complications. Further research is necessary to further confirm these findings in a rural and poor context using objective measures of complications and investigating whether early detection and treatment of depressive symptoms reduces these complications.

Improving discrimination in antepartum depression screening using the Edinburgh Postnatal Depression Scale

BACKGROUND

Universal screening of pregnant women for postpartum depression has recently been recommended; however, optimal application of depression screening tools in stratifying risk has not been defined. The current study examines new approaches to improve the ability of the Edinburgh Postnatal Depression Scale (EPDS) to stratify risk for postpartum depression, including alternate cut points, use of a continuous measure, and incorporation of other putative risk factors.

METHODS

An observational cohort study of 4939 women screened both antepartum and postpartum with a negative EPDS screen antepartum(i.e. EPDS<10). The primary outcome was a probable postpartum major depressive episode(EPDS cut-off ≥10). Area under the receiver operating characteristics curve(AUC), sensitivity, specificity, and predictive values were calculated.

RESULTS

287 women(5.8%) screened positive for postpartum depression. An antepartum EPDS cut-off<5 optimally identified women with a low risk of postpartum depression with a negative predictive value of 97.6%; however, overall discrimination was modest(AUC 0.66, 95%CI: 0.64-0.69); sensitivity was 78.7%, and specificity was 53.8%, and the positive predictive value was low at 9.5%. The negative predictive values were similar(>95%) at all antepartum EPDS cut-off values from 4 to 8. Discrimination was improved(AUC ranging from 0.70 to 0.73) when the antepartum EPDS was combined with a prior history of major depressive disorder before pregnancy.

LIMITATIONS

An inability to assess EPDS subscales and a relatively low prevalence of depression in this cohort.

CONCLUSIONS

Though an antepartum EPDS cut-off score <5 yielded the greatest discrimination identifying women at low risk for postpartum depression, the negative predictive value was insufficient to substitute for postpartum screening.

Use of Online Forums for Perinatal Mental Illness, Stigma, and Disclosure: An Exploratory Model

BACKGROUND

Perinatal mental illness is a global health concern; however, many women with the illness do not get the treatment they need to recover. Interventions that reduce the stigma around perinatal mental illness have the potential to enable women to disclose their symptoms to health care providers and consequently access treatment. There are many online forums for perinatal mental illness and thousands of women use them. Preliminary research suggests that online forums may promote help-seeking behavior, potentially because they have a role in challenging stigma. This study draws from these findings and theoretical concepts to present a model of forum use, stigma, and disclosure.

OBJECTIVE

This study tested a model that measured the mediating role of stigma between online forum use and disclosure of affective symptoms to health care providers.

METHODS

A Web-based survey of 200 women who were pregnant or had a child younger than 5 years and considered themselves to be experiencing psychological distress was conducted. Women were recruited through social media and questions measured forum usage, perinatal mental illness stigma, disclosure to health care providers, depression and anxiety symptoms, barriers to disclosure, and demographic information.

RESULTS

There was a significant positive indirect effect of length of forum use on disclosure of symptoms through internal stigma, b=0.40, bias-corrected and accelerated (BCa) 95% CI 0.13-0.85. Long-term forum users reported higher levels of internal stigma, and higher internal stigma was associated with disclosure of symptoms to health care providers when controlling for symptoms of depression and anxiety.

CONCLUSIONS

Internal stigma mediates the relationship between length of forum use and disclosure to health care providers. Findings suggest that forums have the potential to enable women to recognize and reveal their internal stigma, which may in turn lead to greater disclosure of symptoms to health care providers. Clinicians could refer clients to trustworthy and moderated online forums that facilitate expression of perinatal mental illness stigma and promote disclosure to health care providers.

Sintomas depressivos na gestação e fatores associados: estudo longitudinal

Resumo Objetivo Identificar a frequência de sintomas depressivos no decorrer da gestação e verificar sua associação com variáveis sociodemográficas, obstétricas e de saúde. Métodos Estudo longitudinal realizado com 272 gestantes de 12 unidades de saúde do Município de São Paulo. Os dados foram obtidos por meio de um formulário para as variáveis independentes e da Escala de depressão pós-parto de Edimburgo aplicada nas 20ª, 28ª e 36ª semanas gestacionais. Utilizou-se modelo de equações de estimação generalizadas para avaliar os fatores associados e chances de risco. Resultados A frequência de sintomas depressivos foi de 27,2%, 21,7% e 25,4%. Maior escolaridade, gestação planejada e continuidade da gestação foram fatores de proteção. Sofrer ou ter sofrido violência psicológica foi fator de risco independente do período gestacional. Conclusão A frequência de sintomas depressivos na gestação foi elevada. Os fatores associados foram maior escolaridade, gestação planejada, continuidade da gestação e sofrer ou ter sofrido violência psicológica.

Different patterns of depressive symptoms during pregnancy

Recently, the US Preventive Services Task Force has advocated to screen pregnant and postpartum women for depression. However, we questioned the meaning of a single elevated depression score: does it represent just one episode of depression or do these symptoms persist throughout the entire pregnancy? This study assessed depressive symptoms at each trimester in a cohort of 1813 pregnant women and evaluated whether women with different patterns of depressive symptoms showed other characteristics. Depending on the trimester, elevated depression scores were prevalent in 10-15% of the pregnant women. Up to 4% reported persistent symptoms of depression throughout pregnancy. Different patterns of depressive symptoms were observed, for which persistent symptoms were related to other characteristics than incidentally elevated symptoms. Besides a previous history of mental health problems as best overall predictor, incidentally elevated depression scores were related to major life events. Furthermore, persistently depressive symptoms were related to unplanned pregnancy and multiparity. An EDS assessment at 12 weeks of gestation including three additional items (history of mental health problems, unplanned pregnancy and multiparity) enabled us to identify 83% of the women with persistent depressive symptoms. A depression screening strategy in pregnant women should take into account the potential chronicity of depressive symptoms by repeated assessments in order to offer an intervention to the most vulnerable women.

Prenatal stress alters amygdala functional connectivity in preterm neonates

Exposure to prenatal and early-life stress results in alterations in neural connectivity and an increased risk for neuropsychiatric disorders. In particular, alterations in amygdala connectivity have emerged as a common effect across several recent studies. However, the impact of prenatal stress exposure on the functional organization of the amygdala has yet to be explored in the prematurely-born, a population at high risk for neuropsychiatric disorders. We test the hypothesis that preterm birth and prenatal exposure to maternal stress alter functional connectivity of the amygdala using two independent cohorts. The first cohort is used to establish the effects of preterm birth and consists of 12 very preterm neonates and 25 term controls, all without prenatal stress exposure. The second is analyzed to establish the effects of prenatal stress exposure and consists of 16 extremely preterm neonates with prenatal stress exposure and 10 extremely preterm neonates with no known prenatal stress exposure. Standard resting-state functional magnetic resonance imaging and seed connectivity methods are used. When compared to term controls, very preterm neonates show significantly reduced connectivity between the amygdala and the thalamus, the hypothalamus, the brainstem, and the insula (p < 0.05). Similarly, when compared to extremely preterm neonates without exposure to prenatal stress, extremely preterm neonates with exposure to prenatal stress show significantly less connectivity between the left amygdala and the thalamus, the hypothalamus, and the peristriate cortex (p < 0.05). Exploratory analysis of the combined cohorts suggests additive effects of prenatal stress on alterations in amygdala connectivity associated with preterm birth. Functional connectivity from the amygdala to other subcortical regions is decreased in preterm neonates compared to term controls. In addition, these data, for the first time, suggest that prenatal stress exposure amplifies these decreases.

Impact of gestational risk factors on maternal cardiovascular system

BACKGROUND

Scarce evidence is available on the potential cardiovascular abnormalities associated with some common gestational complications. We aimed to analyze the potential maternal cardiac alterations related to gestational complications, including body mass index (BMI) >25 kg/m(2), gaining excessive weight, or developing antenatal depression.

METHODS

The design of this study was a secondary analysis of a randomized controlled trial. Echocardiography was performed to assess cardiovascular indicators of maternal hemodynamic, cardiac remodeling and left ventricular (LV) function in 59 sedentary pregnant women at 20 and 34 weeks of gestation.

RESULTS

Starting pregnancy with a BMI >25 kg/m(2), gaining excessive weight, and developing antenatal depression had no cardiovascular impact on maternal health (P value >0.002). Depressed women were more likely to exceed weight gain recommendations than non-depressed women (P value <0.002).

CONCLUSIONS

The evaluated gestational complications seem not to induce cardiovascular alterations in hemodynamic, remodeling and LV function indicators. However, developing antenatal depression increases the risk of an excessive weight gain. This finding is potentially important because excessive weight gain during pregnancy associates with a higher risk of cardiovascular diseases (CVD) later in life.
