Marriage and postpartum major depressive disorder: A systematic review and meta-analysis of cohort studies

Many studies have explored the relationships between demographic variables and postpartum major depressive disorder. However, there is no clear conclusion on the impact of different marital statuses and quality on postpartum major depressive disorder. This systematic review and meta-analysis examined the combined effects of different marital status and quality on postpartum major depressive disorder with cohort studies. Two authors independently searched 6 English databases (PubMed, Medline, Web of Science, PsycARTICLES, EBSCOhost and Scopus) and 3 Chinese databases (China Knowledge Resource Integrated Database (CNKI), Weipu database and Wanfang database) from the beginning of database construction to October 25, 2024. Studies that met the inclusion criteria included maternal diagnosis of postpartum major depressive disorder by clinical diagnostic criteria, inclusion of marital status, and reporting risk estimate. There were no language limitations in this study. The quality of the included studies was assessed using the Newcastle-Ottawa scale (NOS). Publication bias was assessed using a funnel plot and Egger's test. Finally, nineteen cohort studies were included in this meta-analysis. Low marital satisfaction was the most significant predictor of postpartum major depressive disorder (pooled RR = 3.47, 95% CI: 1.96, 6.12) followed by being single/divorced/separated/widowed/unmarried (pooled RR = 1.19, 95% CI: 1.02, 1.39). However, there was not a significant relationship between "worsening relationship/dissatisfaction with partner/problems in marital relationship" and postpartum major depressive disorder (pooled RR = 2.30, 95% CI:0.69, 7.62) yet. Marital status and marriage quality impacted heavily on maternal postpartum major depressive disorder. There is an urgent need to focus on family therapy and marital intervention for pregnant women and to enhance the sense of involvement of the husband or partner.

Mothers and Babies Virtual Group (MBVG) for perinatal Latina women: study protocol for a hybrid type-1 effectiveness-implementation randomized controlled trial

BACKGROUND

Immigrant Latinas (who are foreign-born but now reside in the USA) are at greater risk for developing postpartum depression than the general perinatal population, but many face barriers to treatment. To address these barriers, we adapted the Mothers and Babies Course-an evidence-based intervention for postpartum depression prevention-to a virtual group format. Additional adaptations are inclusion of tailored supplemental child health content and nutrition benefit assistance. We are partnering with Early Learning Centers (ELC) across the state of Maryland to deliver and test the adapted intervention.

METHODS

The design is a Hybrid Type I Effectiveness-Implementation Trial. A total of 300 participants will be individually randomized to immediate (N = 150) versus delayed (N = 150) receipt of the intervention, Mothers and Babies Virtual Group (MB-VG). The intervention will be delivered by trained Early Learning Center staff. The primary outcomes are depressive symptoms (measured via the Center for Epidemiologic Studies-Depression Scale), parenting self-efficacy (measured via the Parental Cognition and Conduct Towards the Infant Scale (PACOTIS) Parenting Self-Efficacy subscale), and parenting responsiveness (measured via the Maternal Infant Responsiveness Instrument) at 1-week, 3-month, and 6-month post-intervention. Depressive episodes (Structured Clinical Interview for DSM-V- Disorders Research Version) at 3-month and 6-month post-intervention will also be assessed. Secondary outcomes include social support, mood management, anxiety symptoms, perceived stress, food insecurity, and mental health stigma at 1-week, 3-month, and 6-month post-intervention. Exploratory child outcomes are dysregulation and school readiness at 6-month post-intervention. Intervention fidelity, feasibility, acceptability, and appropriateness will also be assessed guided by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.

DISCUSSION

This study will be one of the first to test the efficacy of a group-based virtual perinatal depression intervention with Latina immigrants, for whom stark disparities exist in access to health services. The hybrid effectiveness-implementation design will allow rigorous examination of barriers and facilitators to delivery of the intervention package (including supplemental components) which will provide important information on factors influencing intervention effectiveness and the scalability of intervention components in Early Learning Centers and other child-serving settings.

Psychometric testing and the predictive validity of the Postpartum Depression Predictors Inventory-Revised (PDPI-R): A longitudinal study with Turkish women

OBJECTIVE

The aim of this study was to investigate the validity and reliability of the prenatal and postnatal versions of the Postpartum Depression Predictors Inventory-Revised (PDPI-R) and to examine the predictive validity of PDPI-R in Turkish women, considering two gold standards to determine postpartum depression (PPD).

METHODS

This prospective longitudinal study was conducted between August 2021 and September 2023. A total of 301 pregnant women participated in the study. Participants completed the PDPI-R during the third trimester of pregnancy (T1) and at 4 weeks postpartum (T2). At T2, participants also completed the Edinburgh Postnatal Depression Scale (EPDS), and women were interviewed using the Structured Clinical Interview for DSM-IV Disorders.

RESULTS

The prenatal version of the PDPI-R predicted PPD with 64% (R:0.64) accuracy on the basis of the EPDS and 78% accuracy (R:0.78) according to DSM IV criteria. The postnatal version of the PDPI-R predicted PPD with 71% (R:0.71) accuracy on the basis of the EPDS and 81% accuracy (R:0.781) based on DSM IV criteria. The cut-off points exhibited the highest sensitivity and specificity values at 8.5 for the prenatal version and 10.5 for the postnatal version.

CONCLUSIONS

The PDPI-R is a valid and reliable screening tool for identifying Turkish women at high risk of developing PPD and for estimating the psychosocial risk associated with PPD.

Depression, anxiety, self-efficacy, and self-esteem in high-risk pregnancy

BACKGROUND

The aim of the study was to evaluate the levels of depression, state and trait anxiety, self-efficacy, and self-esteem among women with high-risk pregnancy due to previous adverse pregnancy outcomes (PAPOs) or prepregnancy diseases (PPD), before and after delivery, compared to controls.

METHODS

An observational longitudinal study on psychological dimensions was conducted on 86 women attending a university referral center for high-risk pregnancy, by administering the Edinburgh Postnatal Depression Scale, the State and Trait Anxiety Inventory, the General Self-Efficacy Scale, and the Self-esteem Scale. A pretest (in the third trimester of pregnancy) and a follow-up measurement session (one month after the delivery) were applied. PAPOs group, PPD group and controls were compared.

RESULTS

The PAPOs group had higher levels of depression compared to the other groups, with above-threshold levels. However, a more relevant decrease in depression was found in the PAPOs group after delivery. Levels of self-efficacy and self-esteem were unexpectedly high during and after pregnancy in all the groups.

CONCLUSIONS

A PAPO represents a risk factor for depression development during pregnancy, whereas a PPD seems to be less relevant in influencing affective dimensions. Surprisingly, all pregnant women, independently of the obstetric risk, showed high levels of self-efficacy and self-esteem.

Prospective analysis of factors associated with perinatal depression

BACKGROUND

Perinatal depression is a significant public health problem that has adverse effects on both mothers and infants. Little research has been conducted on how depressive symptoms change throughout the perinatal period, especially in the Middle East. This study examines changes in depressive symptoms from pregnancy to the postnatal period, and what explains these changes.

METHODS

This prospective study recruited 306 Omani women in the third trimester of pregnancy and followed them up two to eight weeks after delivery. The Edinburgh Postnatal Depression Scale (EPDS), with a cut-off of ≥12, was used to assess depressive symptoms in both the antenatal and postnatal periods. Independent t-tests, one-way ANOVA, Tukey's honestly significant difference test and Chi-square tests were used to analyse the data.

RESULTS

The prevalence of depressive symptoms was 27.12 % (n = 83) during late pregnancy and 29.30 % (n = 81) during the postnatal period. Four groups of women were identified based on the EPDS scores: 1) antenatal depression group (8.82 %; n = 27); 2) ante- and postnatal depression group (14.38 %; n = 44); 3) postnatal depression group (12.09 %; n = 37); and 4) non-depression group (54.90 %; n = 168). Depressive symptoms were associated with low birth weight babies (d = 0.50), which confirms the negative effects of depression on perinatal health outcomes. When compared to the non-depression group, the three depressed groups had higher antenatal Perceived Stress Scale (PSS) scores (ds > 0.52), while the non-depression group had higher antenatal and postnatal Maternity Social Support Scale (MSSS) scores (ds > 0.63), and better relationships with the mother-in-law antenatally (d= 0.57).

CONCLUSION

The present study of this Middle Eastern cohort shows that there were distinct groups of women experiencing perinatal depressive symptoms, influenced by various psychosocial and obstetric factors, which were comparable to those identified in more regularly studied populations. However, this study also identified other novel factors, such as the quality of family relationships. There is a need for additional research into the factors associated with these groups in order to develop appropriate interventions.

Psychological, Psychosocial and Obstetric Differences between Spanish and Immigrant Mothers: Retrospective Observational Study

This study analyzed the influence of psychological and psychosocial factors of pregnant women at an obstetric level. The possible differences between Spaniards and immigrants were studied. This was a retrospective observational study. The sample has been divided into two study cohorts, one consisting of Spanish pregnant women and one consisting of foreign pregnant women. Both completed the Revised Postpartum Depression Predictors Inventory and the Patient Health Questionnaire-9. A total of 15.9% of Spanish women and 23.2% of immigrants had depressive symptoms. Immigrants claim to have less support at the partner, family, and friendship levels than Spaniards. Moreover, 16.4% of Spaniards vs. 8.1% of immigrants had pregnancy complications; Cesarean section was performed in 16.2% of Spaniards vs. 7.9% of immigrants. A greater number of premature births were detected in immigrants than in Spaniards. Access to universal healthcare is a protective factor against socioeconomic and cultural conditions affecting the mental and obstetrical health of immigrants.

Effects of family relationship and social support on the mental health of Chinese postpartum women

Background

Numerous studies suggest that interpersonal relationships and social support influence the development of postpartum depression and sleep quality for women. However, the effect of support from the husband or the mother-in-law has not been thoroughly validated. The current study examined the relative contribution of marital satisfaction, perceived caring of the mother-in-law, and social support on postpartum depression and sleep quality simultaneously in a path model.

Methods

A cross-sectional study was conducted from March to June 2017 in Hebei, China, using a self-report questionnaire. A total of 817 women participated at 6 weeks postpartum. Sociodemographics and information about marital satisfaction, perceived caring of the mother-in-law, social support, postpartum depression, and sleep were collected. Path analysis was used to analyze the cross-sectional data.

Results

The final model had a highly satisfactory fit. Marital satisfaction and perceived caring of mother-in-law had both direct and indirect effects on postpartum depression through social support, but these two variables had only an indirect effect on sleep quality through social support and postpartum depression. Sleep quality is a consequence of postpartum depression at 6 weeks after delivery. The prevalence of minor and major postpartum depressive symptoms at 6 weeks postpartum was 41.49 and 23.13%, respectively. A total of 371 (45.41%) women experienced sleep disturbance at 6 weeks postpartum.

Conclusions

These findings suggest that interpersonal relationships with family members play important roles in postpartum depression and sleep quality through social support in Chinese women. Improving the relationship between new mothers and their husbands or mothers-in-law and then enhancing social support might reduce postpartum depression and sleep disturbance.

Prevalence and associated psychological risk factors of postpartum depression: a cross-sectional study

This cross-sectional study aimed to evaluate the prevalence of postpartum depression and the associated risk factors in a sample of Italian women at three months after delivery. Eighty women were screened by completing the Edinburgh Postnatal Depression Scale (EPDS). Women with a score ≥10 were evaluated as positive and other variables were detected through the administration of the Postpartum Depression Predictors Inventory.The prevalence of postpartum depression in the sample was 11.25% (EPDS score >10). A statistically significant relationship was found between the predisposition to postnatal depression and various risk factors such as prenatal depression, stressful life experiences marital problems. Furthermore, strong emotional and instrumental support from the partner and a good economic status can represent protective factors. It is essential to promote an integrated approach to postpartum affective disorders in which psychosocial risk factors are taken into account, and adequate screening programs are implemented.Impact StatementWhat is already known on this subject? Pregnancy can cause emotional stress for women with consequent development, in some cases, of mood disorders such as postpartum depression.What do the results of this study add? According to this study, women suffering from postpartum depression showed a significant tendency to anxiety and depression, low perceived support from the partner, and low socio-economic status.What are the implications of these findings for clinical practice and/or further research? It would be desirable to promote an integrated approach to postpartum affective disorders in which psychosocial risk factors are taken into account and adequate screening programs are implemented.

Randomized trial examining the effect of exercise and wellness interventions on preventing postpartum depression and perceived stress

BACKGROUND

Approximately 13-19% of postpartum women experience postpartum depression and a majority report at least some stress during the postpartum phase. Traditional interventions such as psychotherapy and antidepressant medications are often not feasible or desirable. The purpose of this study was to examine two low cost, brief, accessible interventions designed to prevent postpartum depression and perceived stress among women at high risk.

METHODS

Participants (n = 450) who were on average four weeks postpartum, had a history of depression before pregnancy, and exercised less than 60 min per week were randomly assigned to one of the following three conditions: (1) 6-month telephone-based exercise intervention; (2) 6-month telephone-based wellness/support intervention (e.g., healthy eating, sleep, and perceived stress); or (3) usual care.

RESULTS

Overall, 2.4% of participants met criteria for depression at 6 months and 3.6% at 9 months with no differences between groups. At 6 months following randomization, median symptoms of depression were significantly lower among wellness participants compared to usual care participants (b = - 1.00, SE = 0.46, p = .03). Perceived stress at 6 months post-randomization was significantly lower among exercise vs. usual care participants (b = - 2.00, SE = .98, p = .04) and exercise vs. wellness participants (b = - 2.20, SE = 1.11, p = .04).

CONCLUSIONS

The wellness intervention was efficacious for preventing symptoms of depression; however, postpartum depression that met the diagnostic criteria was surprisingly low in all conditions among this at risk sample of postpartum women. Exercise interventions may have a protective effect on perceived stress among women at risk for postpartum depression. Practitioners should consider integrating exercise and wellness interventions into postpartum care.

Peripartale psychische Belastung und Auswirkungen auf die frühe Elternschaft

Hintergrund

Peripartale elterliche Angst und Depressivität zeigten Zusammenhänge mit kindlichen emotionalen und Verhaltensauffälligkeiten. Mögliche Erklärungsansätze umfassen pränatal prägende Einflüsse auf das Ungeborene sowie das postpartale Fortwirken psychischer Belastung auf die Eltern-Kind-Beziehung. Dabei kommt dem elterlichen Vertrauen in die eigenen Fähigkeiten eine mögliche protektive Rolle zu, das wiederum durch die eigene psychische Belastung und das kindliche Verhalten maßgeblich beeinträchtigt sein kann.

Fragestellung

Diese Studie untersucht, wie sich pränatale schwangerschaftsspezifische Ängste auf das Vertrauen in die eigenen Fähigkeiten als Mutter in der frühen Elternschaft auswirken und wodurch dieser Effekt vermittelt wird.

Material und Methoden

Als Teil einer prospektiven Längsschnittstudie beantworteten 116 Mütter im letzten Schwangerschaftsdrittel (T0) und der 3. Woche (T1) postpartal Fragebögen zu schwangerschaftsspezifischen Ängsten, mütterlichem Selbstvertrauen, postpartaler Depressivität und kindlicher Irritabilität.

Ergebnisse

Es zeigte sich, dass der Zusammenhang zwischen pränatalen Ängsten und mangelndem mütterlichen Selbstvertrauen nicht über das Erleben kindlicher Irritabilität, sondern entscheidend über das Erleben postpartaler Depressivität vermittelt wurde. Die mütterliche Parität spielte ebenfalls eine Rolle.

Schlussfolgerung

Pränatale schwangerschaftsspezifische Ängste können postpartaler Depressivität vorausgehen und so indirekt das mütterliche Vertrauen in die eigenen Fähigkeiten beeinträchtigen. Die Wachsamkeit für elterliche psychische Belastung und die Weiterentwicklung von Behandlungsansätzen mit Beginn in der Schwangerschaft sind notwendig und erfordern eine enge interprofessionelle Zusammenarbeit zwischen eltern- und kindbezogenen Disziplinen.

Evaluation of the clinical application of the Postpartum Depression Predictors Inventory-Revised for postpartum women in China

AIM

This study was designed to assess the clinical applicability of the Postpartum Depression Predictors Inventory-Revised (PDPI-R) during the 1st month following delivery among women in China and to survey the prevalence of postpartum depression (PPD)-related risk factors included in the PDPI-R in this population.

METHODS

This was a cross-sectional study which recruited 447 women from the People's Liberation Army Hospital in Hefei of Anhui province. All participants completed the Chinese version of the PDPI-R (PDPI-R-C) and the Chinese version of the Edinburgh Postnatal Depression Scale (C-EPDS) within 1 month of delivery. The predictive ability of the PDPI-R was then evaluated through receiver operating characteristic (ROC) curve analyses.

RESULTS

The PDPI-R-C was able to accurately predict 73.2% of PPD cases (area under the ROC curve = 0.732; 95% CI 0.69-0.78) using a cut-off score of 5.5, as defined by a C-EPDS score of ≥10 (sensitivity = 62.8%; specificity = 73.5%; positive predictive value = 74.5%; negative predictive value = 61.5%). All 13 risk factors in the PDPI-R-C other than socioeconomic status and marital status were associated with the risk of PPD.

CONCLUSIONS

The PDPI-R-C was found to be an effective and easy-to-implement tool that has promise as a means of screening for PPD in Chinese populations.

Brexanolone, a GABAA Modulator, in the Treatment of Postpartum Depression in Adults: A Comprehensive Review

Postpartum depression (PPD) is one of the three major categories on the spectrum of postpartum psychiatric syndromes. Postpartum psychiatric syndromes are classified as either postpartum blues, postpartum depression, or postpartum psychosis. Postpartum depression is important to recognize clinically because of the effect it can have on the mother-child bond. The neurosteroid allopregnanolone, a progesterone derivative, is important for its role in positively modulating GABA_A receptors. GABA-mediated signaling has been previously implicated in major depressive disorder. Allopregnanolone-mediated signaling has been identified as an important therapeutic target. Treatment with an allopregnanolone-analog, brexanolone, has been shown to improve depression scores in trials for the treatment of PPD. Brexanolone is a positive allosteric modulator of GABA_A and is the first drug approved by the FDA to treat postpartum depression. Brexanolone enhances the inhibitory effects of GABA_A, restores dysfunctional GABA_A transmembrane channels, and mimics a naturally produced progesterone metabolite that fluctuates during pregnancy and postpartum. One open-label study and two phase two studies have some significant reduction in HAM-D scores after treatment and that the effect was still there 30 days post-treatment. Per the data reported, intravenous infusion of brexanolone could be efficacious and safe for the treatment of women suffering from postpartum depression.

The Factor Reliability and Convergent Validity of the Patient Health Questionnaire-4 Among an International Sample of Pregnant Women

Background: Pregnant women are at an increased risk for anxiety and depression, but a majority of women go untreated due to a high rate of undetected symptoms. The 4-item Patient Health Questionnaire (PHQ-4) is an ultrabrief screening instrument for anxiety and depression with sound psychometric properties demonstrated in the general population and primary care, but not among pregnant women. The aim of this study was to provide initial evidence of the validity and reliability of the PHQ-4 among pregnant women. Materials and Methods: Data from an international sample of 1148 pregnant women who participated in an online cross-sectional survey were examined using a confirmatory factor analysis (CFA) and multigroup analysis approaches. Average chronological and gestational ages were 27.7 years old (standard deviation [SD] = 6.5) and 16.8 weeks (SD = 10.6), respectively. Participants were from diverse cultural backgrounds and English and Spanish speaking (n = 587 and n = 561, respectively). Results: CFA reflected two distinct factors, which accounted for 59% of the proportion of variance in the two anxiety items and 50% in the two depression items. Coefficient H values of 0.74 for anxiety and 0.70 for depression suggested good factor reliability. Conclusions: This is the first study demonstrating initial evidence supporting the validity and reliability of the PHQ-4 in pregnant women. Should this study be replicated, a clinical interview, which is the gold standard procedure, should be included. Regardless, the PHQ-4 may be a useful ultrabrief resource for maternal mental health clinicians and health care providers who need to identify potential cases of anxiety and depression in pregnant women using efficient and evidence-based tools.

Blood manganese levels during pregnancy and postpartum depression: A cohort study among women in Mexico

BACKGROUND

Occupational studies have shown an association between elevated Mn exposure and depressive symptoms. Blood Mn (BMn) naturally rises during pregnancy due to mobilization from tissues, suggesting it could contribute to pregnancy and postpartum depressive symptoms.

OBJECTIVES

To assess the association between BMn levels during pregnancy and postpartum depression (PPD), creating opportunities for possible future interventions.

METHODS

We studied 561 women from the reproductive longitudinal Programming Research in Obesity, Growth, Environment, and Social Stressors (PROGRESS) cohort in Mexico City. BMn was measured at the 2nd and 3rd trimesters, as well as delivery. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess PPD symptoms at 12-months postpartum. We used a generalized linear model assuming a Poisson distribution to assess the association between BMn levels and PPD, with adjustments for age, stress and depressive symptoms during pregnancy, education, socioeconomic status, and contemporaneous blood lead levels.

RESULTS

The mean ± standard deviation (SD) EPDS score at 12-months postpartum was 6.51 ± 5.65, and 17.11% of women met the criteria for possible PPD (score ≥ 13). In adjusted models, BMn during the 3rd trimester (β: 0.13, 95% CI: 0.04-0.21) and BMn levels averaged at the 2nd and 3rd trimester (β: 0.14, 95% CI: 0.02-0.26) had a positive association with EPDS scores at 12 months postpartum. BMn at the 2nd trimester (β: 0.07, 95% CI: -0.09-0.22) and delivery (β: 0.03, 95% CI: -0.04-0.10) had a non-significant positive association with EPDS scores at 12-months postpartum. Stress and depressive symptoms during pregnancy was associated with higher EPDS scores at 12-months postpartum in all of the adjusted models but were only significant when either BMn during 3rd trimester or BMn averaged across 2nd and 3rd trimester was assessed as the exposure.

DISCUSSION

Our results demonstrate that elevated BMn levels during pregnancy predict PPD symptoms and could be a potential pathway for intervention and prevention of PPD.

The Prevalence and Risk Factors for Antenatal Depression Among Pregnant Immigrant and Native Women in Spain

Introduction: The aim was to examine the risk factors of anternatal depression among immigrant and native pregnant women in Spain. Method: A total of 1,524 pregnant women completed the Patient Health Questionnaire and the Postpartum Depression Predictors Inventory-Revised form. Results: The native group reported a lower prevalence (15.2%) compared with immigrant group (25.8%). For immigrants, primiparity, moving, and perceived lack instrumental support from friends or emotional support from partners and family members were significant risk factors. Discussion: The study identified risk factors that can be used for preventive interventions during pregnancy. Significance: Screening and interventions for depression during pregnancy should take migration status into account to maximize effective health care. Also, health providers should consider how migration status can result in different risk factors that affect depression during pregnancy.

Cognitive correlates of women's postpartum depression risk and symptoms: the contribution of dysfunctional beliefs and negative thoughts

Background: Despite the extensive research on interpersonal and clinical risk factors for postpartum depression (PPD), there is a paucity of research on the potential role of cognitive variables (dysfunctional beliefs and negative thoughts) as correlates of PPD symptoms.Aims: This exploratory study aimed to understand the cognitive processes of women at a higher risk (i.e. presenting well-established interpersonal and clinical risk factors) for PPD by: (a) comparing women's dysfunctional motherhood-related beliefs and frequency of automatic thoughts, as a function of their levels of PPD risk and symptoms; (b) examining the cognitive correlates of PPD symptoms, controlling for the presence of well-established risk factors.Method: A cross-sectional internet survey comprising 441 postpartum women was conducted.Results: Women presenting high-risk for PPD showed more dysfunctional motherhood-related attitudes (p < 0.001), more frequent negative thoughts (p < 0.001) and less frequent positive thoughts (p < 0.001) than low-risk women. More dysfunctional beliefs related to maternal responsibility, more frequent negative thoughts related with personal maladjustment and with the metacognitive appraisal of the thoughts' content, and less frequent positive thoughts were found to be significantly associated with PPD symptoms.Conclusion: The inclusion of cognitive variables in risk assessment and preventive efforts for PPD may hold potential to increase its clinical efficacy.

Preliminary Psychometric Testing of the Postpartum Depression Predictors Inventory-Revised (PDPI-R) in Portuguese Women

Introduction Postpartum depression (PPD) is a prevalent condition with a serious impact. The early identification of women at risk for developing PPD allows for primary prevention and the delivery of timely appropriate referrals. This study investigated the validity and reliability of the postnatal version of the Postpartum Depression Predictors Inventory-Revised (PDPI-R), an instrument widely studied internationally, in Portuguese women. Methods The sample consisted of 204 women who participated in an online cross-sectional survey. Participants completed the European Portuguese versions of the PDPI-R, the Edinburgh Postnatal Depression Scale (EPDS), and the Postnatal Negative Thoughts Questionnaire at 1-2 months postpartum. Additionally, ROC analyses were performed to conduct an exploratory analysis of the instruments' predictive validity. Results The prevalence rates of clinical postpartum depressive symptoms were 27.5 and 14.2% using the cut-off scores of 9 and 12, respectively, on the EPDS. The European Portuguese postnatal version of the PDPI-R demonstrated acceptable reliability and satisfactory construct and convergent validity. When using the EPDS > 9 cut-off score, the exploratory analyses yielded a sensitivity of 76.8% and a specificity of 73.0% with a cut-off score of 5.5 [area under the curve = 0.816]. Discussion These preliminary findings encourage the use of the postnatal version of the PDPI-R as a screening tool to identify Portuguese women at high risk for developing PPD. Subsequent assessments are needed to support the routine application of the PDPI-R both in research and for clinical purposes.

A scoping review to determine themes that represent perceptions of self as mother ('ideal mother' vs 'real mother')

Background: Postnatal depression (PND) is a key cause of maternal morbidity, with current systems of initial recognition in the UK detecting only 50% of cases. In attempts to predict those potentially at risk, this review suggests a novel approach. Aim: Implementing the concept of 'ideal mother' versus 'real mother', and asking the woman to compare their 'ideal self' against 'existent self', the aim of this instrument development review was to determine themes from the literature that relate to women's perceptions of self as a mother, and from this identification develop questions for inclusion within a proposed new measure entitled the Self-Image as Mother Scale (SIMS). Method: A scoping review of the literature was carried out to identify themes considered to affect perception of self as mother, and from this identification, evidence-based questions for inclusion in the SIMS were developed. Findings: Themes identified included (1) marital dissatisfaction, (2) inadequate partner support, (3) lack of family support, (4) socioeconomic status and associated poverty, (5) concern about infant, (6) antenatal/postnatal complications, (7) acceptance of infant gender, (8) history of mental health problems, (9) unplanned pregnancy. Conclusions: From this scoping review 18 questions were developed for inclusion in the SIMS, which will then be evaluated for psychometric properties, scale refinement and validation.

Predictive validity of the Postpartum Depression Predictors Inventory-Revised (PDPI-R): A longitudinal study with Portuguese women

OBJECTIVE

This study examined the predictive validity of the prenatal and postnatal versions of the Postpartum Depression Predictors Inventory-Revised (PDPI-R) in European Portuguese women, considering two gold standards to determine postpartum depression (PPD).

DESIGN

Prospective longitudinal study conducted between November 2015 and September 2017.

SETTING

One public referral maternity hospital in the central region of Portugal.

PARTICIPANTS

A total of 140 Portuguese women participated in the study.

MEASUREMENTS

Participants completed the PDPI-R during the second trimester of pregnancy (T1) and at 6 weeks postpartum (T2). At T2, participants also answered the Edinburgh Postnatal Depression Scale (EPDS). During the fourth month postpartum (T3), women were interviewed with the Structured Clinical Interview for DSM-IV Disorders, and between 6 and 9 months postpartum (T4), they completed the EPDS.

FINDINGS

Rates of clinically significant depressive symptoms (EPDS ≥ 10) were 16.4% (23/140) at T2 and 23.2% (23/99) at T4. Six (4.3%) women met the criteria for a clinical diagnosis of PPD (major depressive episode) at T3. Overall, the postnatal version of the PDPI-R performed better than did the prenatal version (average area under the curve = 82% vs. 71%), but both versions accurately predicted women who developed a clinical diagnosis of PPD, at a cut-off score of 4.5 for the prenatal version (sensitivity = 83.3%; specificity = 85.8%) and 9.5 for the postnatal version (sensitivity = 83.3%; specificity = 94.8%).

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Despite the low prevalence of PPD (albeit consistent with prior estimates of major depression at three months postpartum), this clinical condition has very serious consequences for the mother, the baby and the whole family when present. The PDPI-R is a valid screening tool to estimate the psychosocial risk for developing PPD among Portuguese women and can be used in research (e.g., for cross-cultural comparisons) and clinical practice. The recommended cut-off scores could assist health professionals (namely, midwives) in identifying the women who would benefit from appropriate referrals and/or closer monitoring to prevent them from developing PPD.

Rationale, design, and baseline data for the Healthy Mom II Trial: A randomized trial examining the efficacy of exercise and wellness interventions for the prevention of postpartum depression

Approximately 13-19% of women experience postpartum depression and approximately one-third of women who have a history of depression develop depression during the postpartum phase. Exercise is an efficacious intervention for depression among adults; however, few studies have examined the effect of exercise on postpartum depression. The purpose of this study was to conduct a randomized controlled trial examining the effect of exercise and wellness interventions on preventing postpartum depression among women at risk. Specifically, women (n = 450) who were on average 4.35 weeks postpartum and had a history of depression were randomly assigned to one of the following three conditions: (1) Telephone-based exercise intervention; (2) telephone-based wellness/support intervention (covered topics such as sleep, stress, and healthy eating); or (3) usual care. Both interventions lasted six months. The exercise intervention was based on social cognitive theory and the Transtheoretical model and was specifically designed to motivate postpartum women to exercise. The primary dependent variable was depression based on the Structured Clinical Diagnostic Interview (SCID). Secondary dependent variables included the Edinburgh Postnatal Depression Scale, PHQ-9, and Perceived Stress Scale. Potential mediator variables included quality of sleep, postpartum social support, fatigue, and exercise attitudes. Questionnaires were administered at baseline, six, and nine months. The purpose of this paper is to summarize the methodology, study design, and baseline data for this study. This trial will provide important information regarding the efficacy of exercise and wellness interventions for preventing postpartum depression.

Economic and Health Predictors of National Postpartum Depression Prevalence: A Systematic Review, Meta-analysis, and Meta-Regression of 291 Studies from 56 Countries

BACKGROUND

Postpartum depression (PPD) poses a major global public health challenge. PPD is the most common complication associated with childbirth and exerts harmful effects on children. Although hundreds of PPD studies have been published, we lack accurate global or national PPD prevalence estimates and have no clear account of why PPD appears to vary so dramatically between nations. Accordingly, we conducted a meta-analysis to estimate the global and national prevalence of PPD and a meta-regression to identify economic, health, social, or policy factors associated with national PPD prevalence.

METHODS

We conducted a systematic review of all papers reporting PPD prevalence using the Edinburgh Postnatal Depression Scale. PPD prevalence and methods were extracted from each study. Random effects meta-analysis was used to estimate global and national PPD prevalence. To test for country level predictors, we drew on data from UNICEF, WHO, and the World Bank. Random effects meta-regression was used to test national predictors of PPD prevalence.

FINDINGS

291 studies of 296284 women from 56 countries were identified. The global pooled prevalence of PPD was 17.7% (95% confidence interval: 16.6-18.8%), with significant heterogeneity across nations (Q = 16,823, p = 0.000, I2 = 98%), ranging from 3% (2-5%) in Singapore to 38% (35-41%) in Chile. Nations with significantly higher rates of income inequality (R2 = 41%), maternal mortality (R2 = 19%), infant mortality (R2 = 16%), or women of childbearing age working ≥40 h a week (R2 = 31%) have higher rates of PPD. Together, these factors explain 73% of the national variation in PPD prevalence.

INTERPRETATION

The global prevalence of PPD is greater than previously thought and varies dramatically by nation. Disparities in wealth inequality and maternal-child-health factors explain much of the national variation in PPD prevalence.

The effect of sleep pattern changes on postpartum depressive symptoms

Background

Research indicates that poor sleep is associated with postpartum depression; however, little is known regarding this relationship among postpartum women who are at high for postpartum depression. This study examined the relationship between changes in self-reported sleep patterns (from six weeks to seven months postpartum) and depressive symptoms at seven months postpartum among women who were at high risk for postpartum depression.

Methods

Participants (n = 122) were postpartum women who were at an increased risk for postpartum depression (personal or maternal history of depression) and had participated in a randomized exercise intervention trial. For the current trial, participants completed the Pittsburgh Sleep Quality Index and Patient Health Questionnaire-9 (PHQ-9; assessed depression) at six weeks and seven months postpartum.

Results

Overall, sleep problems significantly improved from six weeks to seven months postpartum. However, linear regression analyses indicated that worsening or minimal improvement of sleep problems were associated with higher depressive symptoms at seven month postpartum. Regarding the specific types of sleep problems, self-reported changes in sleep latency (i.e., how long it takes to fall asleep at night), daytime dysfunction (i.e., difficulty staying awake during the day), and sleep quality (i.e., subjective rating of sleep quality) were associated with higher levels of depressive symptoms.

Conclusions

Sleep problems typically improve during the postpartum phase. However, postpartum women who are at high risk for postpartum depression are at an increased risk for depressive symptoms later in the postpartum phase if sleep problems worsen or show only minimal improvement over time. Therefore, at the six-week postpartum clinic visit, women should receive education regarding potential worsening of sleep patterns and strategies for preventing sleep-related problems.

Trial registration

Registered with ClinicalTrials.gov (NCT00961402) on August 18, 2009 prior to the start of the trial.

Long-term postpartum effect of severe maternal morbidity on sexual function

There was limited knowledge on the sexual function in women who have survived severe obstetric complications. The aim of this study was to compare the level of sexual functioning among women with and without severe morbidity at six months postpartum and to identify the factors associated with sexual function scores of women. A prospective double-cohort study design was applied at two tertiary hospitals over a six-month period. Postpartum women with and without severe maternal morbidity were selected as the exposed and the non-exposed group, respectively. The study included 145 exposed and 187 non-exposed women. Those with severe maternal morbidity were significantly ( P < 0.001) older (mean (SD): 31.6 years (6.26) vs. 29.2 years (5.65)) and had longer hospital stays (mean (SD): 5.9 days (3.79) vs. 3.6 days (2.23)). They were also more likely to have delivered preterm (75.9 vs. 93.0) and to have had a caesarean section (80.7 vs. 67.9) than those without severe maternal morbidity. After adjusting for age and mental health, there was no significant difference in Female Sexual Function Index scores ( P = 0.895) between the two groups. Both groups showed the highest sexual dysfunction in pain and the lowest dysfunction in orgasm. Linear regression analyses showed no association between Female Sexual Function Index scores and sociodemographic characteristics, reproductive history, or quality of life. Sexual function in women with severe maternal morbidity did not differ from that in women without severe maternal morbidity. In-depth qualitative studies of women who have experienced potentially life-threatening conditions may improve the understanding of their sexual function.

The relationship between employment status and depression symptomatology among women at risk for postpartum depression

Approximately 13%–19% of new mothers report depression during the postpartum period. Returning to work after childbirth is associated with depression; however, it is unclear if this finding applies to women who are at high risk for postpartum depression. The purpose of this study was to examine the relationship between employment status and depression symptomatology among women at risk for postpartum depression (defined as personal or maternal history of depression). This study was a post hoc analysis from a previously conducted randomized controlled trial. Participants (n = 124; ages 18–42) were 7 months postpartum and had participated in a randomized trial examining the efficacy of an exercise intervention for the prevention of postpartum depression (study was conducted from January 2010 through November 2011). Participants completed questionnaires examining demographic characteristics and psychosocial variables at 6 weeks and 7 months postpartum. The Edinburgh Postnatal Depression Scale was administered at 7 months postpartum to assess depression symptomatology. Sixty-eight percent of the participants reported that they were employed at 7 months postpartum. Employment at 7 months postpartum was associated with lower depression symptomatology (as measured by the Edinburgh Postnatal Depression Scale) after controlling for condition assignment, marital status, and having other children. Among women who worked outside of the home, there were no differences between those who worked full-time versus part-time on depression symptomatology. Employment may be a protective factor for postpartum depression symptomatology; however, we cannot infer causation given this study’s cross-sectional design. Postpartum women at risk for depression who are contemplating employment should consider the possible protective effect of employment on depression.

A review of longitudinal studies on antenatal and postnatal depression

Antenatal depression is a known risk factor for postnatal depression; both are common disorders associated with negative impacts on child development. Few studies have followed up women from pregnancy and through the postnatal period to explore how rates of depression change. This review evaluates recent evidence on depression during pregnancy and after childbirth. A search of Embase, PsychINFO, MEDLINE and Cochrane Reviews was carried out to identify longitudinal studies on antenatal and postnatal depression. Studies that measured depression during pregnancy and up to 1 year after childbirth were evaluated against a set of criteria (e.g. less than 50 % attrition). Of the initial 523 studies identified, 16 studies met the final inclusion criteria with a total of 35,419 women. The average rate of antenatal depression across these studies was 17 and 13 % postnatal depression. The longitudinal nature of the studies revealed that on average 39 % of those who experienced antenatal depression went on to have postnatal depression. Similarly, on average, 47 % of those with postnatal depression had also experienced antenatal depression. On average, almost 7 % of women reported significant depressive symptoms in pregnancy that persisted after childbirth. The review provided evidence that rates of depression tend to be higher during pregnancy than in the first year following childbirth. Furthermore, the longitudinal data show that there is much movement between the groups categorised as depressed or not depressed. There is evidence that postnatal depression is often a continuation of existing antenatal depression.

Psychometric properties of the Postpartum Depression Predictors Inventory–Revised for pregnant women in Mexico

This study assessed the reliability and concurrent validity of the prenatal section of the Postpartum Depression Predictors Inventory–Revised for 250 pregnant women receiving prenatal care in Mexico. The Postpartum Depression Predictors Inventory–Revised has shown adequate psychometric properties for English-speaking perinatal women, but no similar data have been reported for Spanish-speaking samples. The results show that the Postpartum Depression Predictors Inventory–Revised is highly reliable and exhibits adequate concurrent validity compared to the Edinburgh Postnatal Depression Scale. These findings suggest that the Postpartum Depression Predictors Inventory–Revised can be a reliable instrument in prenatal care services for detecting risk factors for perinatal depression in Mexican women and potentially in other Spanish-speaking populations.

A Socioecological Framework to Assessing Depression Among Pregnant Teens

To examine individual, interpersonal, family, and community correlates associated with moderate-to-severe depressive symptoms among pregnant adolescents. A total of 249 primarily African American and Hispanic pregnant adolescents ages 15-18 years were recruited into either an intervention group utilizing Centering Pregnancy prenatal care and case management, or to a comparison group receiving case management only. Moderate-to-severe depressive symptoms were defined as a score ≥16 on the Center for Epidemiologic Studies Depression Scale (CES-D). Intervention and comparison groups did not significantly differ on demographic characteristics or depression scores at baseline. A total of 115 (46.1 %) participants met criteria for moderate-to-severe depressive symptoms at entry into the program. Pregnant adolescents who were moderately-to-severely depressed were more likely to be African American, to have reported limited contact with the father of the baby, and to have experienced prior verbal, physical or sexual abuse. Depressed adolescents also experienced high levels of family criticism, low levels of general support, and exposure to community violence. A significant number of pregnant adolescents were affected by depression and other challenges that could affect their health. Comprehensive interventions addressing these challenges and incorporating partners and families are needed.

Functional status of women with and without severe maternal morbidity: A prospective cohort study

BACKGROUND

Little is known regarding the impact on maternal functional status in women who have survived severe obstetric complications.

OBJECTIVE

To compare the maternal functional status score between women with and without severe morbidity at one month and six months postpartum in Kelantan, Malaysia.

METHODS

A prospective cohort study design was applied at two tertiary referral hospitals over a six-month period. The study population included all postpartum women who gave birth in 2014. Postpartum women with severe maternal morbidity and without severe maternal morbidity were selected as the exposed and non-exposed group, respectively. Functional ability based on the Inventory of Functional Status after Childbirth was used as the main outcome measure. Repeated measure analysis of variance was performed.

RESULTS

A total of 145 and 187 women with and without severe maternal morbidity, respectively, were measured. There were significant differences in Inventory of Functional Status after Childbirth score changes (P<0.001) between women with and without severe maternal morbidity at one month and at six months. Functional ability score of women with severe maternal morbidity was lower at one month postpartum (P=0.001). The most affected domain was infant care (P=0.002).

CONCLUSIONS

Healthcare providers are recommended to assess the short-term functional ability of severe morbid mother in addition to existing routine physical examination. Provision of physical support from spouse and family of the high risk mothers particularly on infant care during their early postpartum period is crucial to optimise health and minimise the negative health outcomes.

Antenatal depressive symptoms associated with specific life events and sources of social support among Italian women

This study aimed to identify different kinds of stressful life events and social support associated with antenatal depressive symptoms in a sample of pregnant Italian women. We conducted the study at a primary health-care centre in an urban area (northeast Italy). Mainly recruited at antenatal classes, 404 eligible pregnant women completed a socio-demographic questionnaire that included questions about the present pregnancy, the Edinburgh Depression Scale (EDS) to estimate the prevalence of depressive symptoms, the Multidimensional Scale of Perceived Social Support and List of Threatening Experiences Questionnaire to investigate the quality and nature of social support and recent negative life events. Of the 404 women, 60 (14.9 %) scored 13 or higher on the EDS. This group reported significantly lower social support from various sources-family, friends, and significant others; only in primiparous women were depressive symptoms significantly related to lower support from friends. Women with EDS scores equal or higher than 13 also reported a higher occurrence of recent stressful life events-specifically, death or a serious problem with a close friend or relative, unemployment, financial problems, and moving or housing difficulties. Regression analyses showed that women with high levels of social support or with a positive experience of pregnancy were less likely to experience antenatal depressive symptoms. Our results underscore the associations among antenatal depression, specific life stressors, and low social support from various sources. Clinical attention to these psychosocial correlates is recommended toward detecting vulnerability to antenatal depressive symptoms.

Longitudinal Course of Risk for Parental Postadoption Depression

OBJECTIVE

To determine whether the Postpartum Depression Predictors Inventory-Revised (PDPI-R) could be used to reveal distinct classes of adoptive parents across time.

DESIGN

Longitudinal data were collected via online surveys at 4 to 6 weeks preplacement, 4 to 6 weeks postplacement, and 5 to 6 months postplacement.

SETTING

Participants were primarily clients of the largest adoption agency in the United States.

PARTICIPANTS

Participants included 127 adoptive parents (68 mothers and 59 fathers).

METHODS

We applied a latent class growth analysis to the PDPI-R and conducted mixed effects modeling of class, time, and class × time interaction for the following categories of explanatory variables: parental expectations, interpersonal variables, psychological symptoms, and life orientation.

RESULTS

Four latent trajectory classes were found. Class 1 (55% of sample) showed a stably low level of PDPI-R scores over time. Class 2 (32%) reported mean scores below the cut-off points at all three time points. Class 3 (8%) started with scores at an intermediate level that increased after postplacement but decreased at 5 to 6 months postplacement. Class 4 (5%) had high mean scores at all three time points. Significant main effects were found for almost all explanatory variables for class and for several variables for time. Significant interactions between class and time were found for expectations about the child and amounts of love and ambivalence in parent's intimate relationship.

CONCLUSION

Findings may help nurses be alert to trajectories of risk for postadoption depression. Additional factors not included in the PDPI-R may be needed to determine risk for postadoption depression in adoptive parents.

Retrospective observation of mental disorders during postpartum period: Results from the Singapore mental health study

Background

The perinatal period has been identified as a period of vulnerability for various disorders (particularly anxiety and depressive disorders), which have been associated with negative outcomes for both mother and infant. The current study utilized data from the Singapore Mental Health Study (SMHS) to examine the temporal relationship between mental disorders and the perinatal period, as well as associated risk factors.

Methods

Life table estimation method was used to derive the estimated hazard rate for any mood or anxiety disorders following pregnancy. Multivariate logistic regression was used to examine the association between socio-demographic factors and onset of mental disorders after the first pregnancy.

Results

Among women with children (n = 2278), 1.5 % were found to have an onset of any mental disorder (i.e., mood disorders, anxiety disorders, alcohol use disorders), within 2 years after pregnancy. A peak in hazard rate was noted at approximately 1 year following pregnancy for anxiety disorders but not mood disorders. Women who were married, employed and physically healthy were less likely to have had developed any mental disorder.

Conclusions

The prevalence of mental disorders during pregnancy and postpartum was found to be low among women with children in our community sample, with increased vulnerability following delivery. The results offer some insight into the occurrence of mental disorders during the perinatal period among women in Singapore.

A cross-sectional analysis of perinatal depressive symptoms among Punjabi-speaking women: are they at risk?

Background

Depression is the leading cause of disability for childbearing women. We examined three specific research questions among Punjabi-speaking women residing in the Fraser Health Authority: 1) What are the prevalence rates of prenatal depressive symptoms? 2) Do Punjabi-speaking women have a higher likelihood of reporting depressive symptoms compared to English-speaking women after controlling for age, level of education and financial worries, and 3) Given the same level of exposure to level of education and financial worries, do Punjabi-speaking women have the same likelihood of reporting depressive symptoms?

Methods

Data originated from the Fraser Health Authority prenatal registration database consisting of pregnant women (n = 9684) who completed a prenatal registration form between June 2009 and August 2010; 9.1 % indicated speaking Punjabi. The Whooley Depression Screen measured depressive symptoms. Chi-square tests and logistic multiple regression were used to examine the rates of reporting depressive symptoms among Punjabi-speaking women compared to English-speaking women.

Results

Punjabi-speaking women are at a higher risk for perinatal depressive symptoms. Women needing an interpreter were more likely to report prenatal depressive symptoms compared to English-speaking women. All registrants who reported financial worries had four and a half times the odds of reporting depressive symptoms. The impact of financial worries was significantly greater in the English-speaking women compared to the Punjabi-speaking women needing an interpreter.

Conclusion

Using an established screening device, Punjabi-speaking women were found to be at higher risk for prenatal depressive symptoms.

ABM Clinical Protocol #18: Use of Antidepressants in Breastfeeding Mothers

A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

Magnitude and risk factors for postpartum symptoms: a literature review

BACKGROUND

The prevalence of postpartum depression worldwide varies from 0.5% to 60.8% in the first 12 months postpartum using self-reported questionnaire. This review aims to update the current magnitude of postpartum depression based on self-reported questionnaire and clinical interview and explore its associated factors in developed and developing countries.

METHODS

A literature search conducted between 2005 and 2014 identified 203 studies, of which 191 used self-reported questionnaire in 42 countries and 21 used structured clinical interview in 15 countries. Nine studies used a combination of self-reported questionnaire and clinical interview.

RESULT

The prevalence of postpartum depression varies from 1.9% to 82.1% in developing countries and from 5.2% to 74.0% in developed countries using self-reported questionnaire. Structured clinical interview shows a much lower prevalence range from 0.1% in Finland to 26.3% in India. Antenatal depression and anxiety, previous psychiatric illness, poor marital relationship, stressful life events, negative attitude towards pregnancy, and lack of social support are significant contributors to postpartum depression.

LIMITATION

All studies are included irrespective of the methodological quality, such as small sample size and their inclusion could affect the generalizability of the results.

CONCLUSION

The current prevalence of postpartum depression is much higher than that previously reported, and similar risk factors are documented. A culturally sensitive cut-off score with adequate psychometric properties of the screening instruments should be available. In future studies, examining the physical, biological, and cultural factors in qualitative studies and in those with adequate methodological qualities is recommended.

Biological and psychosocial predictors of postpartum depression: systematic review and call for integration

Postpartum depression (PPD) adversely affects the health and well being of many new mothers, their infants, and their families. A comprehensive understanding of biopsychosocial precursors to PPD is needed to solidify the current evidence base for best practices in translation. We conducted a systematic review of research published from 2000 through 2013 on biological and psychosocial factors associated with PPD and postpartum depressive symptoms. Two hundred fourteen publications based on 199 investigations of 151,651 women in the first postpartum year met inclusion criteria. The biological and psychosocial literatures are largely distinct, and few studies provide integrative analyses. The strongest PPD risk predictors among biological processes are hypothalamic-pituitary-adrenal dysregulation, inflammatory processes, and genetic vulnerabilities. Among psychosocial factors, the strongest predictors are severe life events, some forms of chronic strain, relationship quality, and support from partner and mother. Fully integrated biopsychosocial investigations with large samples are needed to advance our knowledge of PPD etiology.

Genetic variants in the genes of the stress hormone signalling pathway and depressive symptoms during and after pregnancy

Purpose. The aim of this study was to investigate whether single nucleotide polymorphisms (SNPs) in genes of the stress hormone signaling pathway, specifically FKBP5, NR3C1, and CRHR1, are associated with depressive symptoms during and after pregnancy. Methods. The Franconian Maternal Health Evaluation Study (FRAMES) recruited healthy pregnant women prospectively for the assessment of maternal and fetal health including the assessment of depressiveness. The German version of the 10-item Edinburgh Postnatal Depression Scale (EPDS) was completed at three time points in this prospective cohort study. Visit 1 was at study entry in the third trimester of the pregnancy, visit 2 was shortly after birth, and visit 3 was 6–8 months after birth. Germline DNA was collected from 361 pregnant women. Nine SNPs in the above mentioned genes were genotyped. After construction of haplotypes for each gene, a multifactorial linear mixed model was performed to analyse the depression values over time. Results. EPDS values were within expected ranges and comparable to previously published studies. Neither did the depression scores differ for comparisons among haplotypes at fixed time points nor did the change over time differ among haplotypes for the examined genes. No haplotype showed significant associations with depressive symptoms severity during pregnancy or the postpartum period. Conclusion. The analysed candidate haplotypes in FKBP5, NR3C1, and CRHR1 did not show an association with depression scores as assessed by EPDS in this cohort of healthy unselected pregnant women.

Risk factors for panic disorder in pregnancy: a cohort study

BACKGROUND

The study investigates the prevalence of Panic Disorder (PD) with or without comorbid Major (MD) or Minor Depressive (md) disorder during pregnancy and focuses its attention on the different pattern of risk factors in these two subgroups in a sample of women attending two Centres for Prenatal Care of the Public Health Service.

METHODS

Two-hundred and seventy-seven pregnant women were assessed monthly throughout the whole pregnancy period using the Primary Care Evaluation of Mental Disorders (PRIME-MD) for the screening of PD and the Hospital Anxiety and Depression Scale (HADS) for the evaluation of severity of anxious and depressive symptoms.

RESULTS

Twenty-one women (7.5%) were diagnosed as affected by PD, of whom 12 (57.1%) showed MD or md comorbidity. The development of PD without depressive comorbidity is predicted by a history of previous episodes of Anxiety Disorders while the development of PD plus depressive comorbidity is predicted by a history of previous depressive episodes and by the lack of familiar support.

LIMITATIONS

Given the small sample size of our anxious and depressed women, the present data need to be verified by using larger samples.

CONCLUSIONS

The frequent association between PD and MD or md, the analysis of risk factors and of temporal relationship strongly suggests that the panic-depressive comorbidity might represent in fact depressive disorders with intense anxiety symptoms. These findings raise the question if the PD-depressive association is a true comorbidity or reveals the anxious symptomatology of a depressive disorder (MD or md).

[Predictors of postpartum depression: prospective cohort study]

PURPOSE

This prospective cohort study was done to investigate recall bias to antepartum variables measured at postpartum periods and predictors of postpartum depression.

METHODS

Participants were 215 women who answered a self-administered questionnaire which included demographics, Postpartum Depression Predictors Inventory-Revised and Korean version of Edinburgh Postpartum Depression Scale at antepartum 36-40 weeks and postpartum 2 weeks and 6 weeks. Data were analyzed using kappa, and hierarchical multiple logistic regression.

RESULTS

Agreement between antepartum variables at both antepartum and two postpartum periods was relatively high (κ=.55-.95). Postpartum depression rates were 36.3% and 36.7% at two follow-up points. In hierarchical multiple logistic regression analysis, prenatal depression (OR=4.32, 95% CI: 1.41-13.19; OR=5.19, 95% CI: 1.41-19.08), social support (OR=1.40, 95% CI: 1.18-1.66; OR=1.27, 95% CI: 1.06-1.53) and maternity blues (OR=4.75, 95% CI: 1.89-11.98; OR=4.22, 95% CI: 1.60-11.12) were commonly associated with postpartum depression at two follow-up points. Child care stress (OR=1.85, 95% CI: 1.01-3.37) was only associated with postpartum depression at 2 weeks postpartum and pregnancy intendedness (OR=1.57, 95% CI: 1.09-2.27) was only associated with postpartum depression at 6 weeks postpartum.

CONCLUSIONS

The results indicate a need to apply nursing interventions such as prenatal education and counseling with families from antenatal period.

Perinatal depression--the fourth inflammatory morbidity of pregnancy?: Theory and literature review

Perinatal depression is one of the leading causes of maternal morbidity and mortality. The biological etiology of this disorder remains in question, despite considerable research into the contributions of hormonal imbalance, the role of monoamines, and dysregulation of the HPA axis. Because inflammation is known to be associated with major depression in men and non-perinatal women as well as with other important morbidities of pregnancy (such as preeclampsia, preterm birth, and gestational diabetes), and because these morbidities may correlate with perinatal depression, inflammation may be a common physiological pathway that can also help explain perinatal depression. In this paper, we review the theoretical background of inflammation in perinatal depression and then review the literature concerning immune and inflammatory factors in the etiology and course of perinatal depression. We close with recommendations for future studies in this still relatively unexplored area. Identification and understanding of a common pathophysiology between other pregnancy morbidities and perinatal depression would link physical and mental well-being, likely leading to better treatment and prevention.
