Toward a framework for best practices and research guidelines for perinatal depression research

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.

Understanding the genetics of peripartum depression: Research challenges, strategies, and opportunities

Peripartum depression (PD) is a common mood disorder associated with negative outcomes for mother and child. PD is an understudied disorder in psychiatric genetics, and progress characterizing its genetic architecture has been limited by a lack of disorder-specific research, heterogeneous and evolving phenotypic definitions, inadequate representation of global populations, low-powered studies, and insufficient data amenable to large meta-analyses. The increasing availability of large-scale, population-level efforts, like biobanks, have the potential to accelerate scientific discovery and translational research by leveraging clinical, molecular, and self-report data from hundreds of thousands of individuals. Although these efforts will not fully equip researchers to confront every challenge posed by systemic issues in data collection, such as the reliance on minimal phenotyping strategies, the field is in a position to learn from other successful psychiatric genetic investigations. This review summarizes the current state of PD genetics research and highlights research challenges, including the impact of phenotype depth, measurement, and definition on the replicability and interpretability of genomic research. Recommendations for advancing health equity and improving the collection, analysis, discussion, and reporting of measures for PD research are provided.

Postpartum depression: A role for psychedelics?

BACKGROUND

Postpartum depression (PPD) is a major public health concern and has, at its core, a sense of maternal 'disconnection' - from the self, the infant, and the support system. While PPD bears similarities with MDD, there is increasing evidence for its distinct nature, especially with the unique aspect of the mother-infant relationship. Current treatment modalities for PPD, largely based on those used in major depressive disorder (MDD), have low remission rates with emerging evidence for treatment resistance. It is, therefore, necessary to explore alternative avenues of treatment for PPD.

OBJECTIVE

In this narrative review, we outline the potential therapeutic rationale for serotonergic psychedelics in the treatment of PPD, and highlight safety and pragmatic considerations for the use of psychedelics in the postpartum period.

METHODS

We examined the available evidence for the treatment of PPD and the evidence for psychedelics in the treatment of MDD. We explored safety considerations in the use of psychedelics in the postpartum period.

RESULTS

There is increasing evidence for safety, and encouraging signals for efficacy, of psilocybin in the treatment of MDD. Psilocybin has been shown to catalyse a sense of 'reconnection' in participants with MDD. This effect in PPD, by fostering a sense of 'reconnection' for the mother, may allow for improved mood and maternal sensitivity towards the infant, which can positively impact maternal role gratification and the mother-infant relationship.

CONCLUSION

Psychedelic assisted therapy in PPD may have a positive effect on the mother-infant dyad and warrants further examination.

A Review of Treatments and Clinical Guidelines for Perinatal Depression

Perinatal depression occurs in approximately 1 in 7 women and is considered the most common complication of pregnancy and childbearing. Management of perinatal depression may include a combination of nonpharmacological and pharmacological therapies depending on the severity of symptoms, the stage of gestation, and maternal preference. Healthcare providers are recommended to review current guidelines and provide information to women during pregnancy and postpartum regarding the risks and benefits of nonpharmacological and pharmacological treatment options for perinatal depression. In addition, healthcare providers should consider common barriers to treatment including inadequate screening and social stigma. This article reviews common treatments of perinatal depression as well as the clinical guidelines provided by the American Association of Obstetricians and Gynecologists (ACOG), the American Psychiatric Association (APA), and the US Preventive Services Task Force (USPSTF). Discussion of nonpharmacological therapies includes cognitive behavioral therapy (CBT) and interpersonal therapy (IPT). Pharmacological treatments are reviewed by drug class and include selective serotonin reuptake inhibitors (SSRIs), serotonin/norepinephrine reuptake inhibitors (SNRIs), norepinephrine/dopamine reuptake inhibitors (NDRIs), and tricyclic antidepressants (TCAs). Adjunctive treatments of severe depression, including second-generation antipsychotics (SGAs), are also discussed.

Effect of individual or comorbid antenatal depression and anxiety on birth outcomes and moderation by maternal traumatic experiences and resilience

Background

Although antenatal depression and anxiety (e.g., negative antenatal mental health; NAMH) are individually associated with preterm birth (PTB) and infant neurological impairment, few studies account for comorbidity. Understanding how NAMH impacts PTB and infant neurological functioning by either singular (depression or anxiety) or comorbid status, as well as the way in which these effects can be moderated by additional risk or protective factors (traumatic experiences and trait resiliency) can contribute further understanding of NAMH effects on birth outcomes.

Methods

The sample included 3042 mother-infant dyads from U.S. and South Africa cohorts of the Safe Passage Study (N = 3042). A four-category NAMH variable was created to categorize depression-only, anxiety-only, comorbid, or no NAMH statuses.

Results

There were no NAMH main effects on PTB, however, anxiety-only and comorbid NAMH increased odds of PTB for mothers with higher rates of traumatic life experiences. Anxiety-only and comorbid NAMH were associated with increased odds of newborn neurological impairment, and the effect of comorbid NAMH was stronger for mothers with higher rates of traumatic experiences. Resiliency decreased odds of neurological impairment for mothers who reported depression-only or anxiety-only NAMH.

Limitations

Limitations included potential artefacts of two cohorts that differed in rates of almost all variables, a single time point for measuring NAMH, and lack of pregnancy-specific NAMH measures.

Conclusions

Especially when compared to mothers with no NAMH, comorbidity or singular-condition NAMH statuses associate with negative birth outcomes in nuanced ways, especially when considering additional contexts that may foster or protect against NAMH.

Depression, Anxiety, Resilience, and Coping: The Experience of Pregnant and New Mothers During the First Few Months of the COVID-19 Pandemic

Background: It is well-documented that the mental health of pregnant and postpartum women is essential for maternal, child, and family well-being. Of major public health concern is the perinatal mental health impacts that may occur during the ongoing coronavirus disease 2019 (COVID-19) pandemic. It is essential to explore the symptom experience and predictors of mental health status, including the relationship between media use and mental health. Materials and Methods: The purpose of this study is to evaluate the experiences of pregnant and postpartum women (n = 524) in the United States in the early phase of the COVID-19 pandemic. This cross-sectional online observational study collected psychosocial quantitative and qualitative survey data in adult pregnant and postpartum (up to 6 months postdelivery) women in April-June 2020. Results: Multivariable linear regression models were used to evaluate predictors of depressive symptoms, anxiety, and post-traumatic stress disorder. The most common predictors were job insecurity, family concerns, eating comfort foods, resilience/adaptability score, sleep, and use of social and news media. Qualitative themes centered on pervasive uncertainty and anxiety; grief about losses; gratitude for shifting priorities; and use of self-care methods including changing media use. Conclusions: This study provides information to identify risk for anxiety, depression, and PTSD symptoms in perinatal women during acute public health situations. Women with family and job concerns and low resilience/adaptability scores seem to be at high risk of psychological sequelae. Although use of social media is thought to improve social connectedness, our results indicate that increased media consumption is related to increased anxiety symptoms.

Perinatal depressive symptoms and breastfeeding behaviors: A systematic literature review and biosocial research agenda

BACKGROUND

Breastfeeding is recommended to improve maternal and infant health globally. Depression has been posited to negatively impact breastfeeding, although potential causal and bidirectional pathways between these two phenomena have not been sufficiently characterized. We therefore conducted a systematic review to critically evaluate available evidence on the relationship between perinatal depressive symptoms and breastfeeding behaviors; to identify knowledge gaps and propose a biosocial research agenda to advance our understanding of this topic.

METHODS

A systematic search strategy was applied across seven databases. Data were extracted and aggregated using the matrix method to provide a narrative synthesis of findings.

RESULTS

Thirty-eight studies from 20 countries spanning 1988 through 2018 fit the inclusion criteria. In general, methods across studies were heterogeneous. Fourteen different tools were used to measure perinatal depressive symptoms. Nearly half the studies did not provide breastfeeding definitions. No studies from low-income countries met inclusion criteria. More than half (63%) of studies demonstrated a negative association between depressive symptoms across the perinatal period and less exclusive breastfeeding and/or shorter breastfeeding durations.

LIMITATIONS

Heterogeneity in study design, definitions, assessment tools, and measurement time points limited the comparability of study findings. Causality cannot be assessed.

CONCLUSIONS

Available evidence suggests perinatal depressive symptoms negatively associated with breastfeeding exclusivity and duration, which can lead to suboptimal infant nutrition and detrimental impacts on maternal mental and physical health. To better understand this relationship, we propose including consistent operationalization and assessment of depression and breastfeeding globally and concurrent repeated measures of key biological and social factors.

Mindful Moms: Motivation to Self-Manage Depression Symptoms

BACKGROUND

Nearly 20% of women in the United States experience depressive symptoms during the perinatal period, with known detrimental effects for the mother, child, and family. Depressive symptoms affect motivation to engage in healthy behaviors and self-management of symptoms.

PURPOSE

The purpose of this study was to explore the experiences of women with depressive symptoms who participated in a 12-week mindful physical activity intervention (Mindful Moms) throughout their pregnancy.

STUDY DESIGN

In this qualitative study, we explore the lived experience of women with depressive symptoms who participated in Mindful Moms, a self-management intervention involving nurse-led motivational sessions and group-based mindful physical activity (yoga).

METHODS

Semistructured interviews conducted at approximately 6 weeks postpartum provided rich qualitative data that was analyzed using a phenomenological approach.

RESULTS

Twenty-five women participated. Findings suggest that participants in Mindful Moms felt empowered to manage their depressive symptoms through the combination of four key factors: a newly recognized need for help, a felt sense of physical and emotional benefit from participation, the power of shared safe space with other pregnant women, support from study staff, and an overall sense of empowerment.

CLINICAL IMPLICATIONS

Mindful Moms appears to be a feasible and acceptable approach to enhancing motivation to self-manage depressive symptoms in pregnant women. Nurses working with childbearing women should be aware of the potential benefits of self-management strategies, such as mindful physical activity and motivational interviewing, for women facing perinatal depressive symptoms.

A Comprehensive Conceptual Framework to Guide Clinical Practice and Research About Mental Health During the Perinatal Period

Perinatal mood and anxiety disorders (PMADs) affect up to 20% of pregnant and postpartum women and can have negative sequelae for maternal-child health. Nurses with clinical and research roles are on the front line of efforts to assess for and assist with prevention and intervention with PMAD symptoms. Thus, they can play an essential role in enhancing the mental well-being of women in the perinatal period and maternal-child health outcomes. The aim of this article is to assist nurses in this work by outlining the Comprehensive Model of Mental Health during the Perinatal Period, a conceptual framework for considering clinical and research opportunities to enhance perinatal mental health. The framework uses key principles that recognize biopsychoneuroimmunologic mechanisms involved in mental health; the key role that the experience of matrescence ("becoming a mother") plays in mental health and maternal-child health; and the mother-infant dyad as the functional unit during the perinatal period. Examples are provided of how the key principles of this framework might be used to enhance research and clinical practice about PMADs and, ultimately, enhance maternal-child health outcomes.

Is Postpartum Depression Different From Depression Occurring Outside of the Perinatal Period? A Review of the Evidence

Whether a major depressive episode occurring in the postpartum period (i.e., postpartum depression [PPD]) is sufficiently distinct from major depressive episodes occurring at other times (i.e., major depressive disorder) to warrant a separate diagnosis is a point of debate with substantial clinical significance. The evidence for and against diagnostic distinction for PPD is reviewed with respect to epidemiology, etiology, and treatment. Overall, evidence that PPD is distinct from major depressive disorder is mixed and is largely affected by how the postpartum period is defined. For depression occurring in the early postpartum period (variably defined, but typically with onset in the first 8 weeks), symptom severity, heritability, and epigenetic data suggest that PPD may be distinct, whereas depression occurring in the later postpartum period may be more similar to major depressive disorder occurring outside of the perinatal period. The clinical significance of this debate is considerable given that PPD, the most common complication of childbirth, is associated with immediate and enduring adverse effects on maternal and offspring morbidity and mortality. Future research investigating the distinctiveness of PPD from major depressive disorder in general should focus on the early postpartum period when the rapid decline in hormones contributes to a withdrawal state, requiring profound adjustments in central nervous system function.
