Postpartum depression is a family affair: addressing the impact on mothers, fathers, and children

Identifying and assessing the benefits of interventions for postnatal depression: a systematic review of economic evaluations

Background

Economic evaluations of interventions for postnatal depression (PND) are essential to ensure optimal healthcare decision-making. Due to the wide-ranging effects of PND on the mother, baby and whole family, there is a need to include outcomes for all those affected and to include health and non-health outcomes for accurate estimates of cost-effectiveness. This study aimed to identify interventions to prevent or treat PND for which an economic evaluation had been conducted and to evaluate the health and non-health outcomes included.

Methods

A systematic review was conducted applying a comprehensive search strategy across eight electronic databases and other sources. Full or partial economic evaluations of interventions involving preventive strategies (including screening), and any treatments for women with or at-risk of PND, conducted in OECD countries were included. We excluded epidemiological studies and those focussing on costs only. The included studies underwent a quality appraisal to inform the analysis.

Results

Seventeen economic evaluations met the inclusion criteria, the majority focused on psychological /psychosocial interventions. The interventions ranged from additional support from health professionals, peer support, to combined screening and treatment strategies. Maternal health outcomes were measured in all studies; however child health outcomes were included in only four of them. Across studies, the maternal health outcomes included were quality-adjusted-life-years gained, improvement in depressive symptoms, PND cases detected or recovered, whereas the child health outcomes included were cognitive functioning, depression, sleep and temperament. Non-health outcomes such as couples’ relationships and parent-infant interaction were rarely included. Other methodological issues such as limitations in the time horizon and perspective(s) adopted were identified, that were likely to result in imprecise estimates of benefits.

Conclusions

The exclusion of relevant health and non-health outcomes may mean that only a partial assessment of cost-effectiveness is undertaken, leading to sub-optimal resource allocation decisions. Future research should seek ways to expand the evaluative space of economic evaluations and explore approaches to integrate health and non-health outcomes for all individuals affected by this condition. There is a need to ensure that the time horizon adopted in studies is appropriate to allow true estimation of the long-term benefits and costs of PND interventions.

Spouses' prenatal autonomous motivation to have a child and postpartum depression symptoms

OBJECTIVES

Maternal postpartum depression symptoms (PDS) are linked with negative personal, family, and child developmental outcomes. However, paternal PDS, let alone dyadic process, are understudied. Grounded in the Self-Determination Theory of motivation, this longitudinal study examined whether mothers' and fathers' type of prenatal motivation to have a child predicted depression symptoms 3-6 months after birth.

METHOD

The data (N = 90 heterosexual couples) were analyzed using the Actor-Partner Interdependence Model.

RESULTS

Dyadic analyses showed that a person's prenatal autonomous motivation to have a child significantly predicted own PDS and partner's PDS. Importantly, these finding were equivalent across genders.

CONCLUSIONS

The findings highlight the importance of dyadic prenatal motivational processes as antecedents of PDS.

A systematic review of the associations between maternal nutritional biomarkers and depression and/or anxiety during pregnancy and postpartum

BACKGROUND

Nutritional requirements need to be met in order to adapt to pre- and postnatal changes. Our aim was to systematically review the evidence of associations between nutritional biomarkers and psychological distress during pregnancy and in the first postnatal year.

METHODS

MEDLINE, EMBASE, PsycINFO, Scielo, LILACS, clinicaltrials.gov, International Clinical Trials Registry, Cochrane Library, Scopus and Web of Science databases were searched for articles from inception to 4/15/2016. Studies of maternal nutritional biomarkers in blood (fatty acids/micronutrients/amino acids) and associations with psychological distress (depression/anxiety/stress) were included. Two independent reviewers extracted data based on study designs, participants, outcomes, exposures, and association measures.

RESULTS

Thirty-eight studies were included. A total of 13 studies showed divergent or no associations between serum/plasma/erythrocyte fatty acid concentrations and depression/anxiety during pregnancy and postpartum. Changes in serum cholesterol levels from pregnancy to postpartum showed a significant inverse correlation with depression in one out of three studies. Five out of seven studies found an inverse association between serum vitamin D levels and pre- and postnatal depression. Plasma tryptophan levels were inversely correlated with postnatal depression scores in three out of four studies. We identified that one out of two studies presented no significant association between vitamin B₁₂/folate/ferritin concentrations and depression in postpartum.

LIMITATIONS

There was higher variability between association measures, time and scales of depression and anxiety assessments.

CONCLUSIONS

The majority of high-quality studies suggest that lower vitamin D levels may be associated with postpartum depression. However, further evidence is needed for guiding clinical practice on nutritional biomarkers.

Depressive Symptoms and Influencing Factors in Low-Risk Mothers

INTRODUCTION

Depressive symptoms burden not only postpartum women, but can also compromise partner relationships and mother-infant interactions. With approximately 15% of women affected by perinatal mood and anxiety disorders (PMADs) each year, maternity care providers must be sensitive to personal characteristics and complaints that influence women's potential to develop postpartum depression (PPD). The purpose of the study was to identify personal characteristics and modifiable factors associated with depressive symptoms in low-risk postpartum women.

METHODS

A descriptive, correlational design was used to identify predictors of depressive symptoms among mothers who were considered to be at low risk for PPD. Self-report data related to mood, stress, sleep disturbance, and fatigue were collected near the sixth week post-delivery from women (N = 62) in a southern US state.

RESULTS

The levels of stress and reports of sleep disturbance approached clinical concern in the low-risk sample (n = 62), in addition to being positively correlated depressive symptoms. Cesarean delivery was also associated with increased depressive symptoms and predictive of depression symptoms when combined with perceived chronic stress, sleep disturbance, and fatigue.

DISCUSSION

The findings underscore the importance of assessing maternal mental health and adjustment during the postpartum period. While some mothers may not report depressive symptoms at post-delivery visits, they may be experiencing symptoms that predispose them to a mood disorder. Using a more holistic approach to postpartum care, with concern for both physical and mental well-being, may be a necessary shift to promote health in new mothers and families.

The role of community pharmacists in the identification and ongoing management of women at risk for perinatal depression: A qualitative study

BACKGROUND

While pharmacists are among the most accessible primary health professionals within a mother's healthcare team to identify potential cases of perinatal depression (PND), very little in the literature suggests that this role has been explored.

AIM

The aim of this study was to explore community pharmacists' perspectives on their potential roles in perinatal mental health promotion (recognition and health education) and the factors affecting these roles.

METHODS

In total, 20 semi-structured, in-depth interviews were conducted with community pharmacists.

RESULTS

Most pharmacists highlighted their significant roles in recognising PND symptoms and providing medication-related support to perinatal mothers. Barriers to service provision included inter-professional role boundaries, the lack of established referral systems and service remuneration and the lack of adequate training in mental health.

CONCLUSION

Pharmacists could potentially reinforce their involvement in mental health promotion activities.

The Effectiveness and Cost-Effectiveness of Web-Based and Home-Based Postnatal Psychoeducational Interventions for First-Time Mothers: Randomized Controlled Trial Protocol

BACKGROUND

In addition to recuperating from the physical and emotional demands of childbirth, first-time mothers are met with demands of adapting to their social roles while picking up new skills to take care of their newborn. Mothers may not feel adequately prepared for parenthood if they are situated in an unsupported environment. Postnatal psychoeducational interventions have been shown to be useful and can offer a cost-effective solution for improving maternal outcomes.

OBJECTIVE

The objective of this study was to examine the effectiveness and cost-effectiveness of Web-based and home-based postnatal psychoeducational programs for first-time mothers on maternal outcomes.

METHODS

A randomized controlled three-group pre- and posttests experimental design is proposed. This study plans to recruit 204 first-time mothers on their day of discharge from a public tertiary hospital in Singapore. Eligible first-time mothers will be randomly allocated to either a Web-based psychoeducation group, a home-based psychoeducation group, or a control group receiving standard care. The outcomes include maternal parental self-efficacy, social support, psychological well-being (anxiety and postnatal depression), and cost evaluation. Data will be collected at baseline, 1 month, 3 months, and 6 months post-delivery.

RESULTS

The recruitment (n=204) commenced in October 2016 and was completed in February 2017, with 68 mothers in each group. The 6-month follow-up data collection was completed in August 2017.

CONCLUSIONS

This study may identify an effective and cost-effective Web-based postnatal psychoeducational program to improve first-time mothers' health outcomes. The provision of a widely-accessed Web-based postnatal psychoeducational program will eventually lead to more positive postnatal experiences for first-time mothers and positively influence their future birth plans.

HealthyDads.ca: What Do Men Want in a Website Designed to Promote Emotional Wellness and Healthy Behaviors During the Transition to Parenthood?

BACKGROUND

Up to 18% of men experience depression and/or anxiety during the transition to parenthood. Interventions designed specifically to promote the mental health of men during the transition to parenthood are scarce. Internet-delivered interventions may be acceptable and far-reaching in enhancing mental health, parenting knowledge, and healthy behaviors in expectant or new fathers.

OBJECTIVE

To guide the development of Healthydads.ca, a website designed to enhance mental health and healthy behaviors in expectant fathers, a needs assessment was conducted to identify fathers' perspectives of barriers to seeking help for emotional wellness, informational needs, and factors affecting the decision to visit such a website.

METHODS

One hundred and seventy-four men whose partners were expecting, or had recently given birth, in 3 Canadian provinces (Quebec, Ontario, and Alberta) completed a Web-based survey inquiring about information needs related to psychosocial aspects of the transition to parenthood, lifestyle behaviors, parenting, and factors associated with the decision to visit a father-focused website.

RESULTS

Most men (155/174, 89.1%) reported accessing the Internet to obtain information on pregnancy and spent an average of 6.2 hours online per month. Seeking information about parenting on the Internet was reported by 67.2% (117/174) of men, with a mean of 4.4 hours per month of online searching. Top barriers to seeking help to improve emotional wellness during the perinatal period were: no time to seek help/assistance (130/174, 74.7%), lack of resources available in the health care system (126/174, 72.4%), financial costs associated with services (118/174, 67.8%), and feeling that one should be able to do it alone (113/174, 64.9%). Information needs that were rated highly included: parenting/infant care (52.9-81.6%), supporting (121/174, 69.5%) and improving (124/174, 71.3%) relationship with their partner, work-family balance (120/174, 69.0%), improving sleep (100/174, 57.5%), and managing stress (98/174, 56.3%). Perceiving the website as personally relevant (151/174, 86.8%), credible (141/174, 81.0%), effective (140/145, 80.5%), and having an easy navigation structure (141/174, 81.0%) were identified as important factors related to a first website visit. Providing useful (134/174, 77.0%) and easy to understand (158/174, 90.8%) information, which was also free of charge (156/174, 89.7%), were considered important for deciding to prolong a website visit. Providing the possibility to post questions to a health professional (133/174, 76.4%), adding new content regularly (119/174, 68.4%), and personal motivation (111/174, 63.8%) were factors identified that would encourage a revisit.

CONCLUSIONS

Our findings demonstrate that there is substantial interest among expectant and new fathers for using Internet-delivered strategies to prepare for the transition to parenthood and support their mental health. Specific user and website features were identified to optimize the use of father-focused websites.

The effect of perinatal depression treatment for mothers on parenting and child development: A systematic review

Antenatal and postpartum depression are very common and have significant consequences for mothers and their children. This review examines which antenatal depression (AD) and postpartum depression (PPD) treatment interventions are most efficacious in improving parenting and/or child development. CINAHL, Scopus, Cochrane Systematic Reviews, Cochrane Controlled Trials, Medline (OVID), Embase (OVID), PsychINFO, PsycARTICLES, AMED, and reference lists were searched. Randomized controlled trials (RCTs) and quasi-experimental studies assessing the effect of AD, PPD, or both treatment interventions on parenting and/or child development were included. Meta-analysis was conducted using random effects when possible. Thirty-six trials (within 40 articles) met criteria for review. Interventions include interpersonal psychotherapy (IPT), cognitive behavioural therapy (CBT), peer support, maternal-child interaction guidance, and other interventions, such as massage. For AD, IPT, CBT, and massage produced large effects on parenting (e.g. adjustment and attention toward infant) and child development (e.g. behaviour). For PPD, maternal-child interaction guidance and psychotherapeutic group support produced large effects on parenting (e.g. sense of competence) and child development (e.g. cortisol). However, meta-analysis revealed nonsignificant effects of IPT on maternal-child attachment and CBT on parenting stress. Promising findings exist for IPT, CBT, maternal-child interaction guidance, massage, and psychotherapeutic group support for specific parenting and/or child development outcomes. Additional RCTs using measures already employed in the literature are required to conduct necessary meta-analysis and fully elucidate treatment effects.

I. INTRODUCTION: UNDERSTANDING THE TRANSITION TO SIBLINGHOOD FROM A DEVELOPMENTAL PSYCHOPATHOLOGY AND ECOLOGICAL SYSTEMS PERSPECTIVE

The birth of an infant sibling is a common occurrence in the lives of many toddler and preschool children. Early childhood is also a time for the emergence of disruptive behavior problems that may set the stage for later problem behaviors. The current study examined individual differences in young children’s behavioral and emotional adjustment after the birth of a sibling in an effort to uncover developmental trajectories reflecting sudden and persistent change (maladaptation), adjustment and adaptation (resilience), gradual linear increases, and no change (stability and continuity). Growth mixture modeling (GMM) was conducted with a sample of 241 families expecting their second child using a longitudinal research design across the first year after the sibling’s birth (prenatal, 1, 4 8 and 12 months) on seven syndrome scales of the Child Behavior Checklist (CBCL 1.5–5:(Achenbach & Rescorla, 2000 ): aggression, attention problems, anxiety/depression, emotional reactivity, withdrawal, somatic complaints, and sleep problems. For all scales, multiple classes describing different trajectory patterns emerged that reflected predominantly intercept differences; children high on problem behavior after the birth were those high before the birth. There was no evidence of a sudden, persistent maladaptive response indicating children underwent a developmental crisis for any of the problem behaviors examined. Most children were low on all problem behaviors examined and showed little change or actually declined in problem behaviors over time, although some children did experience more pronounced changes in the borderline clinical or clinical range. Only in the case of aggressive behavior was there evidence of an Adjustment and Adaptation Response showing a sudden change (prenatal to 1 month) that subsided by 4 months, suggesting that some young children react to stressful life events but adapt quickly to these changing circumstances. Further, children’s withdrawal revealed a curvilinear, quadratic path, suggesting children both increased and decreased in their withdrawal over time. Guided by a developmental ecological systems framework, we employed data mining procedures to uncover the child, parent, and family variables that best discriminated the different trajectory classes and found that children’s temperament, coparenting, parental self-efficacy, and parent-child attachment relationships were prominent in predicting children’s adjustment after the birth of an infant sibling. Finally, when trajectory classes were used to predict sibling relationship quality at 12 months, children high on aggression, attention problems, and emotional reactivity in the year after the birth engaged in more conflict and less positive involvement with the infant sibling at the end of the first year.

Maternal depression in Syrian refugee women recently moved to Canada: a preliminary study

BACKGROUND

Refugee women are almost five times more likely to develop postpartum depression than Canadian-born women. This can be attributed to various difficulties they faced before coming to Canada as well as during resettlement. Moreover, refugee women usually face many obstacles when accessing health services, including language and cultural barriers, as well as unique help-seeking behaviors that are influenced by various cultural and practical factors. There has been a recent, rapid influx of Syrian refugees to Canada, and many of them are childbearing women. However, little is known about the experiences that these women have encountered pre- and post-resettlement, and their perceptions of mental health issues. Thus, there is an urgent need to understand refugee women's experiences of having a baby in Canada from a mental health perspective.

METHODS

A mixed methods research design included 12 Syrian refugee women who migrated to Saskatoon in 2015-16 and who were either pregnant or 1 year postpartum. The data were collected during a single focus group discussion and a structured questionnaire.

RESULTS

Our results showed that more than half of participants have depressive symptoms, half of them have anxiety symptoms, and one sixth have PTSD symptoms. Three major themes emerged from the qualitative data: 1) Understanding of maternal depression; 2) Protective factors for mental health; and 3) Barriers to mental health services.

CONCLUSIONS

Maternal depression is an important feature in Syrian refugee women recently resettled in Canada. Reuniting these women with their families and engaging them in culturally appropriate support programs may improve their mental health outcomes.

Appraisal of the Psychiatric Diagnostic Screening Questionnaire in a perinatal cohort: The APrON study

BACKGROUND

Depression and anxiety are routinely screened as part of perinatal care. However, other Axis 1 disorders and specific anxiety disorders are less likely to be screened or assessed as part of obstetric care. The objective of this study was to determine whether the Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a potentially useful tool to screen for psychiatric conditions in pregnant and postpartum women in a community setting.

METHODS

We compared the prevalence of DSM Axis I disorders obtained on the PDSQ with: (1) the prevalence of these disorders reported in previous studies of pregnant and postpartum women, and (2) scores obtained on the Edinburgh Postpartum Depression Scale (EPDS) and the Symptom Checklist-90-Revised (SCL-90R) anxiety scale. Data were obtained from the Alberta Pregnancy Outcomes and Nutrition (APrON) study.

RESULTS

The PDSQ was completed by 1575 women prenatally and 1481 postnatally. The three most prevalent PDSQ conditions were social phobia, somatic disorder, and obsessive-compulsive disorder (OCD). The prevalence of social phobia, alcohol disorder, OCD and psychosis were higher in the APrON cohort compared with statistics in the literature. The proportion of women meeting depression and anxiety cut-offs on the PDSQ were lower than for the EPDS and the SCL-90R. The Cohens Kappa index ( k) indicated poor to fair agreement between the measures in classifying pregnant women as depressed or anxious.

CONCLUSIONS

The PDSQ subscales may not be appropriate for the pregnant population. Research into instruments more specific to pregnant and postpartum women are needed to determine the prevalence of psychiatric disorders in this population.

Maternal sensitivity and social support protect against childhood atopic dermatitis

BACKGROUND

Many studies have identified associations between qualities of maternal-child relationships and childhood asthma, but few have examined associations with childhood atopic dermatitis (AD), a common precursor to asthma. Moreover, maternal psychological distress, including prenatal and postnatal depression, anxiety and stress, may increase risk, while social support from partners may reduce risk for childhood AD. We sought to uncover the association between maternal-infant relationship qualities (maternal sensitivity towards infant behavioral signals, controlling behavior, and unresponsiveness) and child AD after accounting for risk (i.e., prenatal and postnatal maternal depression, anxiety and stress) and protective (i.e., social support) factors.

METHODS

We conducted a secondary analysis of data collected on a subsample of 242 women and their infants enrolled during pregnancy in the ongoing Alberta Pregnancy Outcomes and Nutrition cohort study. Inclusion criteria required mothers to be >16 years of age, English speaking and <22 weeks gestational age at enrollment. Data on depression, anxiety and stress in the prenatal and postnatal periods and physician diagnosis of childhood AD at 18 months were gathered via maternal report. Maternal sensitivity, unresponsiveness and controlling behaviours were assessed via videotaped observations using the Child-Adult Relationship Experimental (CARE)-Index at 6 months of infant age.

RESULTS

Higher maternal sensitivity, or the inability of the mother to appropriately understand and respond to infant needs based on behavioral signals, predicted reduced odds of AD independent of and in combination with low prenatal and postnatal anxiety and high paternal support. After adjustment, higher maternal controlling behaviours and unresponsiveness also predicted greater odds of AD.

CONCLUSIONS

Low maternal sensitivity is a risk factor for childhood AD, independently and in combination with perinatal anxiety and low social support. Thus, interventions that improve maternal-infant relationship quality, especially sensitivity, reduce anxiety and improve social support from partners could reduce odds of childhood AD.

Do Successive Preterm Births Increase the Risk of Postpartum Depressive Symptoms?

Background

Postpartum depression and preterm birth (PTB) are major problems affecting women's health. PTB has been associated with increased risk of postpartum depressive symptoms (PDS). However, it is unclear if PTB in women with a prior history of PTB is associated with an incremental risk of PDS. This study aims to determine if PTB in women with a prior history of PTB is associated with an incremental risk of PDS.

Methods

Data come from the 2009–2011 national Pregnancy Risk Assessment Monitoring System. Study sample included 55,681 multiparous women with singleton live births in the index delivery. Multiple logistic regression was used to examine the association between PTB and PDS.

Results

The risk of PDS was 55% higher in women with PTB in both deliveries (aRR = 1.55; 95% CI = 1.28–1.88) and 74% higher in women with PTB in the index delivery only (aRR = 1.74; 95% CI = 1.49–2.05), compared to women with term deliveries.

Conclusions

Preterm birth is a risk factor for PDS. PTB in women with a prior history of PTB is not associated with an incremental risk of PDS. Routine screening for PDS should be conducted for all women and closer monitoring should be done for high risk women with PTB.

Predictors of Postpartum Depression in Partnered Mothers and Fathers from a Longitudinal Cohort

Postpartum depression (PPD) is a growing mental health concern in new mothers and fathers. The purpose of this study was to determine the predictors of depression at 3 months postpartum, comparing depressed couples to couples with only one depressed partner or no depressed partner, using data from the Alberta Pregnancy Outcomes and Nutrition study. Data from mothers and fathers were collected at second trimester and 3 months postpartum. Results showed predictors of PPD in mothers to be low household income, high prenatal depressive symptoms, and postnatally, low social support and higher number of stressful life events. Fathers had similar predictors, including low household income, high prenatal depressive symptoms, and postnatally low social support and smoking. Compared with non-depressed couples, factors that predicted PPD in both mothers and fathers in couples included low income, high prenatal depressive symptoms in mothers and low prenatal social support reported by fathers.

Fathering moderates the effects of maternal depression on the family process

Maternal depression negatively impacts children's development, yet few studies have focused on fathering and the family process in cases of maternal depression. A community cohort of married/cohabitating women was recruited on the second postbirth day (N = 1,983) and maternal depression repeatedly assessed across the first year and again at 6 years to form two cohorts: mothers chronically depressed from birth to 6 (N = 46) and nondepressed controls (N = 103). At 6 years, mother–child, father–child, and family interactions were observed. In families of depressed mothers, both mother and father exhibited lower sensitivity and higher intrusiveness, and children displayed lower social engagement during interactions with mother and father. Fathering moderated the effects of maternal depression on the family process. When fathers showed low sensitivity, high intrusiveness, and provided little opportunities for child social engagement, the family process was less cohesive, implying a decrease in the family's harmonious, warm, and collaborative style. However, in cases of high father sensitivity, low intrusiveness, and increased child engagement, the family process was unaffected by maternal depression. Findings describe both comparability and compensatory mechanisms in the effects of fathering on family life when maternal care is deficient, highlight the buffering role of fathers, and underscore the importance of father-focused interventions when mothers are depressed.

Prevalence and predictors of positive screening for postpartum depression in minority parturients in the South Bronx

It is reported that the rates of perinatal depressive disorders are high in ethnic minority groups from non-English speaking countries. However, very few studies have compared the prevalence of positive screening for postpartum depression (PPD) in minority communities living in an inner city. The goal of this study is to determine the prevalence and the predictors of positive screening for postpartum depression in minority parturients in the South Bronx. The study is a chart review of 314 minority parturients, Black or Hispanic, screened for postpartum depression using the Edinburgh Postnatal Depression Scale (EPDS) tool. The overall prevalence of a positive EPDS screen among Black and Hispanic women was similar, 24.04 and 18.75%, respectively. The Black immigrant cohort had comparable positive screens with 23.81 as African Americans. Hispanic women born in the USA had the least prevalence of positive screens, 7.14%, and those who moved from the Dominican Republic and Puerto Rico had a prevalence of 17.24% of positive screens. The women who immigrated from Mexico, Central America, or South America had the highest prevalence of positive screens for PPD, 32.26%. As to the socioeconomic status (SES), there was a significant increase of 27.04 vs. 13.95% (P < 0.019) in positive screens for PPD for the unemployed mothers. Overall, Black and Hispanic parturients had similar rates of positive screens for PPD. Among the Hispanic women, immigrants had higher rates of positive screens, with those from Mexico, Central, and South America as the highest. The hospital experience did not affect the rates of positive screens. Neither did the SES with one exception; those unemployed had the higher rates of positive screens.

Single bolus low-dose of ketamine does not prevent postpartum depression: a randomized, double-blind, placebo-controlled, prospective clinical trial

PURPOSE

Postpartum depression is a common complication of childbirth. In the last decade, it has been suggested that subdissociative-dose ketamine is a fast-acting antidepressant. We aimed to investigate the efficacy of low-dose ketamine administered during caesarean section in preventing postpartum depression.

METHODS

Using a randomized, double-blind, placebo-controlled design, 330 parturients who were scheduled to undergo caesarean section were enrolled in this trial. The parturients were randomly assigned to receive intravenous ketamine (0.25 mg/kg diluted to 10 mL with 0.9% saline) or placebo (10 mL of 0.9% saline) within 5 min following clamping of the neonatal umbilical cord. The primary outcome was the degree of depression, which was evaluated using the Edinburgh Postnatal Depression Scale (EPDS) (a threshold of 9/10 was used) at 3 days and 6 weeks after delivery. The secondary outcome was the numeric rating scale score of pain at 3 day and 6 week postpartum.

RESULTS

No significant differences were found in the prevalence of postpartum depression between the two groups at 3 days and 6 weeks after delivery. The pain scores measured at 3 days postoperatively were not significantly different between the groups, whereas the scores measured at 6 week postpartum were significantly reduced in the treatment group compared with the saline group (P = 0.014).

CONCLUSIONS

Intra-operative low-dose ketamine (0.25 mg/kg) does not have a preventive effect on postpartum depression.

Stress induces equivalent remodeling of hippocampal spine synapses in a simulated postpartum environment and in a female rat model of major depression

Stress and withdrawal of female reproductive hormones are known risk factors of postpartum depression. Although both of these factors are capable of powerfully modulating neuronal plasticity, there is no direct electron microscopic evidence of hippocampal spine synapse remodeling in postpartum depression. To address this issue, hormonal conditions of pregnancy and postpartum period were simulated in ovariectomized adult female Sprague-Dawley rats (n=76). The number of hippocampal spine synapses and the depressive behavior of rats in an active escape task were investigated in untreated control, hormone-withdrawn 'postpartum', simulated proestrus, and hormone-treated 'postpartum' animals. After 'postpartum' withdrawal of gonadal steroids, inescapable stress caused a loss of hippocampal spine synapses, which was related to poor escape performance in hormone-withdrawn 'postpartum' females. These responses were equivalent with the changes observed in untreated controls that is an established animal model of major depression. Maintaining proestrus levels of ovarian hormones during 'postpartum' stress exposure did not affect synaptic and behavioral responses to inescapable stress in simulated proestrus animals. By contrast, maintaining pregnancy levels of estradiol and progesterone during 'postpartum' stress exposure completely prevented the stress-induced loss of hippocampal spine synapses, which was associated with improved escape performance in hormone-treated 'postpartum' females. This protective effect appears to be mediated by a muted stress response as measured by serum corticosterone concentrations. In line with our emerging 'synaptogenic hypothesis' of depression, the loss of hippocampal spine synapses may be a novel perspective both in the pathomechanism and in the clinical management of postpartum affective illness.

Immediate postpartum mood assessment and postpartum depressive symptoms

BACKGROUND

Negative affect (NA) and positive affect (PA) in the early postpartum period have been associated with postpartum depressive symptoms, but the exact relationship is not well understood. This study aimed to determine if NA and PA in the immediate postpartum period predicted postpartum depressive symptoms over and above well-established predictors (previous trauma, history of depression).

METHODS

Participants were prospectively recruited from a Mother-Baby Unit at a large Midwestern academic medical center in the United States from April 2011 to April 2014. Participants (N=526) completed the Daily Experiences Questionnaire (DEQ), a self-report measure which assessed NA and PA, within three days post-delivery. Participants then reported their depressive symptoms at two weeks (n=364) and twelve weeks postpartum (n=271).

RESULTS

Hierarchical regression analyses indicated that low PA and high NA after birth significantly predicted depressive symptoms early (at 2 weeks) and later (at 12 weeks) in the postpartum period, over and above previous traumatic experiences and history of depression.

LIMITATIONS

The sample was relatively homogenous, and data were from self-report instruments.

CONCLUSIONS

The current study found NA and PA in the days immediately after birth predicted depressive symptoms at multiple time points in the postpartum period. Because the perinatal period places women at a higher risk for depressive symptomatology, prevention and early intervention are critical. Measuring affect in hospitals immediately after birth may provide a more normalized set of items that is predictive of later depression, which will allow physicians to identify those at highest risk for developing depressive symptoms.

New Fathers' Perinatal Depression and Anxiety-Treatment Options: An Integrative Review

More than 10% of fathers experience depression and anxiety during the perinatal period, but paternal perinatal depression (PPND) and anxiety have received less attention than maternal perinatal mental health problems. Few mainstream treatment options are available for men with PPND and anxiety. The aim of this literature review was to summarize the current understanding of PPND and the treatment programs specifically designed for fathers with perinatal depression. Eight electronic databases were searched using a predefined strategy, and reference lists were also hand searched. PPND and anxiety were identified to have a negative impact on family relationships, as well as the health of mothers and children. Evidence suggests a lack of support and tailored treatment options for men having trouble adjusting to the transition to fatherhood. Of the limited options available, cognitive behavioral therapy, group work, and blended delivery programs, including e-support approaches appear to be most effective in helping fathers with perinatal depression and anxiety. The review findings have important implications for the understanding of PPND and anxiety. Future research is needed to address the adoption of father-inclusive and father-specific models of care to encourage fathers' help-seeking behavior. Inclusion of male-specific requirements into support and treatment options can improve the ability of services to engage new fathers. Psychotherapeutic intervention could assist to address the cognitive differences and dissonance for men adjusting to the role of father, including male identity and role expectations.

Paternal depression during pregnancy and postpartum: An international Delphi study

BACKGROUND

Fathers are at risk for depression during a mother's gestation and postpartum. Assessment, detection, and treatment are hampered by the lack of consensus on this issue. The purpose of this study was to reach expert consensus through the Delphi method on the defining factors of depression in peripartum fathers.

METHODS

Purposive sampling resulted in the surveying of 14 international expert panelists. The study used a modified Delphi approach in which experts participated in two rounds of open-ended and scale questionnaires, followed by two rounds of opportunities to adjust their responses and/or comment on evolving data until consensus was achieved.

RESULTS

Experts responded to 10 questions on terminology, diagnostics, symptomology, risk/protective factors, biological factors, assessment tools/protocol, cost implications, and key stakeholders. Of these 10 questions presented for discussion, the analysis resulted in 197 coded themes. Consensus was met for 119 of the 197 coded responses (60.41%).

LIMITATIONS

Diversity of opinion within this Delphi Study was excluded for the sake of consensus. Regression to the mean may have occurred after continuous surveying and when evolving results were shared with panelists. Critics of Delphi methodologies have pointed to the issue of small expert samples typically used and the subjectivity of "expert."

CONCLUSION

Consensus identified diagnostic criteria and symptomology that differentiates the paternal experience of peripartum depression. Experts indicated the importance of a father's social context, biological risk factors, limitations of current assessment tools, key stakeholders, and potential financial costs. Stakeholders on this issue would benefit from translating consensus into assessment and treatment.

Barriers and Facilitators to the Use of Mental Health Services by Women With Elevated Symptoms of Depression and Their Partners

This qualitative descriptive study explored the barriers and facilitators to the use of mental health services reported by women with elevated symptoms of depression in the postpartum period and their partners. Data were collected through individual semi-structured interviews of 30 heterosexual couples. Content analysis revealed five principal barriers and facilitators: (a) accessibility and proximity, (b) appropriateness and fit, (d) stigma, (e) encouraged to seek help, and (f) personal characteristics. The study highlights the importance of barriers and facilitators to be taken into consideration in order to promote the use of mental health services for women with elevated symptoms of depression in the postpartum period.

Disturbed Sleep and Postpartum Depression

The perinatal period introduces a myriad of changes. One important but often overlooked change is an increased reporting of sleep disturbance. Although casually regarded as a consequence of pregnancy or postpartum, there is emerging evidence implicating significant sleep disturbance, characterized by insomnia symptoms and/or poor sleep quality, with adverse outcomes, such as an increase in depressive symptomatology or the development postpartum depression (PPD). Significant consequences may arise as a result including issues with maternal-infant bonding, effective care for the infant, and behavioral or emotional difficulties in the infant. This review discusses the relevant literature as to how disturbed sleep during pregnancy as well as in the postpartum may increase the risk for PPD.

A Thematic Analysis of Stigma and Disclosure for Perinatal Depression on an Online Forum

BACKGROUND

Perinatal mental illness is a global health concern; however, many women do not get the treatment they need to recover. Some women choose not to seek professional help and get no treatment because they feel stigmatized. Online forums for various health conditions, including perinatal mental health, can be beneficial for members. Little is known about the role that online forums for perinatal mental illness play in reducing stigma and subsequent disclosure of symptoms to health care providers and treatment uptake.

OBJECTIVE

This study aimed to examine stigma and disclosure in forums and describe any potential disadvantages of forum use.

METHODS

An online forum for mothers was examined and 1546 messages extracted from 102 threads from the antenatal and postnatal depression section. These messages were subjected to deductive systematic thematic analysis to identify common themes regarding stigma and disclosure of symptoms and potential disadvantages of forum use.

RESULTS

Two major themes were identified: stigma and negative experiences of disclosure. Stigma had 3 subthemes: internal stigma, external stigma, and treatment stigma. Many women were concerned about feeling like a "bad" or "failed" mother and worried that if they disclosed their symptoms to a health care provider they would be stigmatized. Posts in response to this frequently encouraged women to disclose their symptoms to health care providers and accept professional treatment. Forum discourse reconstructed the ideology of motherhood as compatible with perinatal mental illness, especially if the woman sought help and adhered to treatment. Many women overcame stigma and replied that they had taken advice and disclosed to a health care provider and/or taken treatment.

CONCLUSIONS

Forum use may increase women's disclosure to health care providers by challenging their internal and external stigma and this may strengthen professional treatment uptake and adherence. However, a few posts described negative experiences when disclosing to health care providers.

Peripartum depression in parents with multiple sclerosis and psychiatric disorders in children

BACKGROUND

Although many individuals with multiple sclerosis (MS) experience depression, there are no studies on the frequency and effect of peripartum depression among parents with MS.

OBJECTIVE

To examine the frequency of peripartum depression in individuals with MS and its potential association with children's psychiatric disorders.

METHODS

We conducted a cohort study in British Columbia, Canada, using linked health databases, of parents with MS and their children, and age-matched unaffected parent-child dyads. The diagnosis of peripartum depression, MS and psychiatric disorders in children was based on information from hospital admission, physician visit and drug prescription claims.

RESULTS

Peripartum depression was significantly more common among MS parents (n = 360) versus unaffected (n = 1207) parents (25.8% vs 18.5%, p value 0.02), especially among MS affected fathers versus unaffected fathers (25.7% vs 10.2%, p value < 0.001). The incidence of psychiatric disorders in children was 3.3 and 2.7 per 100 child-years among children with and without an MS parent, respectively. The rate of psychiatric disorders was significantly higher in children with an MS parent (vs without, hazard ratio (HR): 1.34; 95% confidence interval (CI): 1.03-1.74) and among children with parents who had peripartum depression (HR: 1.87; 95% CI: 1.36-2.55).

CONCLUSION

Parental MS is associated with a higher risk of peripartum depression and increases the risk of psychiatric disorders in children.

The effects of gestational stress and Selective Serotonin reuptake inhibitor antidepressant treatment on structural plasticity in the postpartum brain--A translational model for postpartum depression

This article is part of a Special Issue "Parental Care". Postpartum depression (PPD) is a common complication following childbirth experienced by one in every five new mothers. Although the neural basis of PPD remains unknown, previous research in rats has shown that gestational stress, a risk factor for PPD, induces depressive-like behavior during the postpartum period. Moreover, the effect of gestational stress on postpartum mood is accompanied by structural modifications within the nucleus accumbens (NAc) and the medial prefrontal cortex (mPFC)-limbic regions that have been linked to PPD. Mothers diagnosed with PPD are often prescribed selective serotonin reuptake inhibitor (SSRI) antidepressant medications and yet little is known about their effects in models of PPD. Thus, here we investigated whether postpartum administration of Citalopram, an SSRI commonly used to treat PPD, would ameliorate the behavioral and morphological consequences of gestational stress. In addition, we examined the effects of gestational stress and postpartum administration of Citalopram on structural plasticity within the basolateral amygdala (BLA) which together with the mPFC and NAc forms a circuit that is sensitive to stress and is involved in mood regulation. Our results show that postpartum rats treated with Citalopram do not exhibit gestational stress-induced depressive-like behavior in the forced swim test. In addition, Citalopram was effective in reversing gestational stress-induced structural alterations in the postpartum NAc shell and mPFC. We also found that gestational stress increased spine density within the postpartum BLA, an effect which was not reversed by Citalopram treatment. Overall, these data highlight the usefulness of gestational stress as a valid and informative translational model for PPD. Furthermore, they suggest that structural alterations in the mPFC-NAc pathway may underlie stress-induced depressive-like behavior during the postpartum period and provide much needed information on how SSRIs may act in the maternal brain to treat PPD.

Sleep and postpartum depression

PURPOSE OF REVIEW

The perinatal period introduces a myriad of changes. One important but often overlooked change is the increased risk for sleep disturbance. Although casually regarded as a consequence of pregnancy or postpartum, there is emerging evidence to suggest that women with significant sleep disturbance, characterized by insomnia symptoms and/or poor sleep quality, are more likely to report an increase in depressive symptomatology or develop postpartum depression (PPD). Significant consequences may arise as a result including issues with maternal-infant bonding, effective care for the infant and behavioral or emotional difficulties in the infant. This review discusses the relevant literature as to how disturbed sleep during pregnancy as well as in the postpartum may increase the risk for PPD.

RECENT FINDINGS

Symptoms of insomnia and poor sleep quality are independently associated with greater depressive symptoms across pregnancy and throughout postpartum. Likewise, both can negatively impact the ability to mother effectively.

SUMMARY

The presence of insomnia or sleep disturbance during the perinatal period is a risk factor for depressive symptoms. Women with depression are at an increased risk of developing sleep disturbance thereby increasing depressive symptomatology. This bidirectional and additive relationship needs more clinical attention as both sleep disturbance and depression are noted risk factors for adverse pregnancy outcomes.

Interventions for postnatal depression assessing the mother-infant relationship and child developmental outcomes: a systematic review

Postnatal depression (PND) has negative effects on maternal well-being as well as implications for the mother–infant relationship, subsequent infant development, and family functioning. There is growing evidence demonstrating that PND impacts on a mother’s ability to interact with sensitivity and responsiveness as a caregiver, which may have implications for the infant’s development of self-regulatory skills, making the infant more vulnerable to later psychopathology. Given the possible intergenerational transmission of risk to the infant, the mother–infant relationship is a focus for treatment and research. However, few studies have assessed the effect of treatment on the mother–infant relationship and child developmental outcomes. The main aim of this paper was to conduct a systematic review and investigate effect sizes of interventions for PND, which assess the quality of the mother–infant dyad relationship and/or child outcomes in addition to maternal mood. Nineteen studies were selected for review, and their methodological quality was evaluated, where possible, effect sizes across maternal mood, quality of dyadic relationship, and child developmental outcomes were calculated. Finally, clinical implications in the treatment of PND are highlighted and recommendations made for further research.

A systematic review of the relationship between postpartum sleep disturbance and postpartum depression

OBJECTIVE

To examine the relationship between postpartum sleep disturbance and postpartum depression and describe the characteristics and demographics of the samples.

DATA SOURCES

Electronic databases Medline, PubMed, Cochrane, EPOC, CINAHL, ProQuest, and Psych INFO. In addition, hand searches of bibliographies supplemented the electronic search.

STUDY SELECTION

English language primary studies on the relationship between postpartum sleep disturbance and postpartum depression were included. Thirteen observational studies met the inclusion criteria.

DATA EXTRACTION

Data that specified the relationship between sleep disturbance and postpartum depression were extracted from the studies. The data were organized per author, year, participants, setting, country, demographics, design, sample size, outcomes, evidence, and effect size.

DATA SYNTHESIS

The effect size indicating the relationship between sleep disturbance and postpartum depression across the studies ranged between 0.4 and 1.7. There was evidence of a strong relationship between sleep disturbance and postpartum depression; however, the participants in the 13 studies were predominantly educated, middle class, older than age 30 years, and White. Likewise, the definition and measurement of postpartum sleep varied across the studies, which increased the possibility of bias.

CONCLUSIONS

Further research within the postpartum period involving underserved, younger women and samples with more diversity in race and ethnicity are needed.

Peripartum depression and anxiety as an integrative cross domain target for psychiatric preventative measures

Exposure to high levels of early life stress has been identified as a potent risk factor for neurodevelopmental delays in infants, behavioral problems and autism in children, but also for several psychiatric illnesses in adulthood, such as depression, anxiety, autism, and posttraumatic stress disorder. Despite having robust adverse effects on both mother and infant, the pathophysiology of peripartum depression and anxiety are poorly understood. The objective of this review is to highlight the advantages of using an integrated approach addressing several behavioral domains in both animal and clinical studies of peripartum depression and anxiety. It is postulated that a greater focus on integrated cross domain studies will lead to advances in treatments and preventative measures for several disorders associated with peripartum depression and anxiety.

Associations of dietary intake and plasma concentrations of eicosapentaenoic and docosahexaenoic acid with prenatal depressive symptoms in Japan

The association between depression and omega-3 polyunsaturated fatty acids, including eicosapentaenoic and docosahexaenoic acid, continues to gain focus. In this study, we examined whether dietary intakes and plasma concentrations of eicosapentaenoic and docosahexaenoic acid were associated with depressive symptoms during pregnancy. Healthy Japanese women with singleton pregnancies were recruited at a university hospital in Tokyo between 2010 and 2012. The depressive-symptom group included participants with Edinburgh Postnatal Depression Scale scores greater than eight. Of the 329 participants, 19 (5.8%) had depressive symptoms. Lower plasma docosahexaenoic acid concentration was significantly associated with prenatal depressive symptoms. Women with depressive symptoms had a higher rate of pregnancy-associated nausea than those with non-depressive symptoms (52.6% vs 28.7%, respectively). Although we adjusted for the presence of pregnancy-associated nausea, dietary fatty acid intake was not associated with depressive symptoms in the multiple logistic regression analyses. Further large studies would be required to examine any preventive effect of dietary fatty acid intake on depressive symptoms among pregnant women.

Pilot early intervention antenatal group program for pregnant women with anxiety and depression

This study aims to examine the acceptability and effectiveness of an antenatal group intervention designed to reduce the severity of depression and anxiety symptoms and improve maternal attachment in pregnant women with current or emerging depression and anxiety. Women who participated in the program completed pre- and posttreatment measures of depression (Centre of Epidemiological Studies Depression Scale) and Edinburgh Postnatal Depression Scale), anxiety (State-Trait Anxiety Inventory) and maternal attachment (Condon Maternal Antenatal Attachment Scale). Participants also completed a satisfaction questionnaire and provided general feedback about the group intervention and experience. A total of 48 women (M = 26 weeks of gestation) commenced and 37 (77 %) completed at least 80 % of the six session group intervention. Significant improvements with moderate to large effect sizes were observed for depression as measured on the Centre of Epidemiological Studies Depression Scale (CES-D) (p < 0.001), Edinburgh Postnatal Depression Scale (EPDS) (p < 0.001), state anxiety (p < 0.001) and maternal attachment (p = 0.006). Improvements in posttreatment depression scores on the EPDS were maintained at 2 months postpartum. Participants reported that the program had met their expectations. Partners (n = 21) who completed evaluation forms indicated that their attendance had improved their awareness of their partner's mental health issues and resources available to their family and would recommend the program to other fathers. These preliminary findings suggest that our antenatal group program is an effective and acceptable intervention for a clinical sample of women and partners. It is a feasible addition or alternative treatment option to perinatal mental health care. Future directions could involve more comprehensive randomised controlled trials (RCT) to examine the effectiveness of the group intervention.

Gestational stress induces persistent depressive-like behavior and structural modifications within the postpartum nucleus accumbens

Postpartum depression (PPD) is a common complication following childbirth experienced by one in every five new mothers. Pregnancy stress enhances vulnerability to PPD and has also been shown to increase depressive-like behavior in postpartum rats. Thus, gestational stress may be an important translational risk factor that can be used to investigate the neurobiological mechanisms underlying PPD. Here we examined the effects of gestational stress on depressive-like behavior during the early/mid and late postpartum periods and evaluated whether this was accompanied by altered structural plasticity in the nucleus accumbens (NAc), a brain region that has been linked to PPD. We show that early/mid (postpartum day 8) postpartum female rats exhibited more depressive-like behavior in the forced swim test as compared with late postpartum females (postpartum day 22). However, 2 weeks of restraint stress during pregnancy increased depressive-like behavior regardless of postpartum timepoint. In addition, dendritic length, branching and spine density on medium spiny neurons in the NAc shell were diminished in postpartum rats that experienced gestational stress although stress-induced reductions in spine density were evident only in early/mid postpartum females. In the NAc core, structural plasticity was not affected by gestational stress but late postpartum females exhibited lower spine density and reduced dendritic length. Overall, these data not only demonstrate structural changes in the NAc across the postpartum period, they also show that postpartum depressive-like behavior following exposure to gestational stress is associated with compromised structural plasticity in the NAc and thus may provide insight into the neural changes that could contribute to PPD.

Antidepressant treatment for postnatal depression

BACKGROUND

Postnatal depression is a common disorder that can have adverse short- and long-term effects on maternal morbidity, the new infant and the family as a whole. Treatment is often largely by social support and psychological interventions. It is not known whether antidepressants are an effective and safe choice for treatment of this disorder. This review was undertaken to evaluate the effectiveness of different antidepressants and to compare their effectiveness with other forms of treatment, placebo or treatment as usual. It is an update of a review first published in 2001.

OBJECTIVES

To assess the effectiveness of antidepressant drugs in comparison with any other treatment (psychological, psychosocial or pharmacological), placebo or treatment as usual for postnatal depression.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Group's Specialized Register (CCDANCTR) to 11 July 2014. This register contains reports of relevant randomised controlled trials (RCTs) from the following bibliographic databases: The Cochrane Library (all years), MEDLINE (1950 to date), EMBASE, (1974 to date) and PsycINFO (1967 to date). We also searched international trial registries and contacted pharmaceutical companies and experts in the field.

SELECTION CRITERIA

We included RCTs of women with depression with onset up to six months postpartum that compared antidepressant treatment (alone or in combination with another treatment) with any other treatment, placebo or treatment as usual.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from the trial reports. We requested missing information from investigators wherever possible. We sought data to allow an intention-to-treat analysis. Random effects meta-analyses were conducted to pool data where sufficient comparable studies were identified.

MAIN RESULTS

We included six trials with 596 participants in this review. All studies had a randomised controlled parallel group design, with two conducted in the UK, three in the US and one in Israel. Meta-analyses were performed to pool data on response and remission from studies comparing antidepressants with placebo. No meta-analyses could be conducted for other comparisons due to the small number of trials identified.Four studies compared selective serotonin reuptake inhibitors (SSRIs) with placebo (two using sertraline, one using paroxetine and one using fluoxetine; 233 participants in total). In two of these studies both the experimental and placebo groups also received psychological therapy. Pooled risk ratios based on data from three of these studies (146 participants) showed that women randomised to SSRIs had higher rates of response and remission than those randomised to placebo (response: RR 1.43, 95% CI 1.01 to 2.03; remission: RR 1.79, 95% CI 1.08 to 2.98); the fourth study did not report data on response or remission.One study (254 participants) compared antidepressant treatment with treatment as usual (for the first four weeks) followed by listening visits. The study found significantly higher rates of improvement in the antidepressant group than treatment-as-usual group after the first four weeks, but no difference between antidepressants and listening visits at the later follow-up. In addition, one study comparing sertraline with nortriptyline (a tricyclic antidepressant) found no difference in effectiveness (109 participants).Side effects were experienced by a substantial proportion of women, but there was no evidence of a meaningful difference in the number of adverse effects between treatment arms in any study. There were very limited data on adverse effects experienced by breastfed infants, with no long-term follow-up. All but one of the studies were assessed as being at high or uncertain risk of attrition bias and selective outcome reporting. In particular, one of the placebo-controlled studies had over 50% drop-out.

AUTHORS' CONCLUSIONS

The evidence base for this review was very limited, with a small number of studies and little information on a number of important outcomes, particularly regarding potential effects on the child. Risk of bias, for example from high attrition rates, as well as low representativeness of participants (e.g. exclusion of women with severe or chronic depression in several trials) also limit the conclusions that can be drawn.Pooled estimates for response and remission found that SSRIs were significantly more effective than placebo for women with postnatal depression. However the quality of evidence contributing to this comparison was assessed as very low owing to the small sample size for this comparison (146 participants from three studies), the risk of bias in included studes and the inclusion of one study where all participants in both study arms additionally received psychological therapy. There was insufficient evidence to conclude whether, and for whom, antidepressant or psychological/psychosocial treatments are more effective, or whether some antidepressants are more effective or better tolerated than others. There is also inadequate evidence on whether the benefits of antidepressants persist beyond eight weeks or whether they have short- or long-term adverse effects on breastfeeding infants.Professionals treating women with severe depression in the postnatal period will need to draw on other evidence, including trials among general adult populations and observational studies of antidepressant safety when breastfeeding (although the potential for confounding in non-randomised studies must be considered). More RCTs are needed with larger sample sizes and longer follow-up, including assessment of the impact on the child and safety of breastfeeding. Further larger-scale trials comparing antidepressants with alternative treatment modalities are also required.
