Mother-infant interaction in women with depression in pregnancy and in women with a history of depression: the Psychiatry Research and Motherhood - Depression (PRAM-D) study

Blood transcriptomic signatures associated with depression, or the risk for depression, in pregnant women from the Psychiatry Research And Motherhood - Depression (PRAM-D) study

During pregnancy multiple biological systems undergo consistent modifications, in particular the hormonal axes and the immune system. Moreover, while it is well known that pregnant women suffering from depression show alterations in these systems, the exact underlying mechanisms are still not clear. For this reason, in this study, we explored the blood transcriptomic profile and related pathways in 41 pregnant women with a current diagnosis of depression, 23 pregnant women, who were not depressed in pregnancy but, because of a history of depressive episodes, were considered at high risk of developing antenatal depression (history-only), and 28 pregnant women who had never experienced depression in their life, including the current pregnancy. Based on resulting differentially expressed genes, we identified 28 molecular pathways modulated in depressed women compared with controls, with a main association with increased B cell activity, while history-only women showed 52 pathways differentially modulated compared with controls, involving lower cytotoxic T cell activity and higher pro-inflammatory pathways activity. Conversely, depressed women showed a differential modulation of 75 pathways, compared with history-only women, associated with increased activity of allo- and auto-immunity and pro-inflammatory pathways. Overall, our results suggest a main role of immunity within the context of perinatal depression, and of a differential modulation of specific immune processes underlying the development of depression and the associated risk.

The impact of gestational diabetes mellitus on perceived mother-infant bonding: a qualitative study

BACKGROUND

The prevalence of gestational diabetes mellitus (GDM) is rapidly increasing. It is associated with adverse physical and mental health outcomes for women and their babies. Mother-infant bonding is important for maternal health and infant development, but the effect of GDM on mother-infant bonding has not been examined.

OBJECTIVE

To explore and describe the impact of GDM on perceived mother infant-bonding in the antenatal and postnatal period.

METHODS

Qualitative, individual, semi-structured interviews were conducted with 33 women from diverse backgrounds with current or previous GDM. Data were analysed using reflexive inductive thematic analysis.

RESULTS

Three main themes were generated from the analysis: 1) Concern for baby's health and its impact on bonding; 2) GDM management, the pregnancy experience, and bonding; 3) Continuity and discontinuity of the impact on bonding between the antenatal and postnatal periods.

CONCLUSION

It was found that GDM can have both positive and negative impacts on perceived mother-infant bonding, which appear to change over the course of the perinatal period. Further observational research is needed to assist in understanding the impact of GDM on mother-infant bonding and the potential mediating effect of mental disorders, including depression.

Canadian Network for Mood and Anxiety Treatments 2024 Clinical Practice Guideline for the Management of Perinatal Mood, Anxiety, and Related Disorders: Guide de pratique 2024 du Canadian Network for Mood and Anxiety Treatments pour le traitement des troubles de l'humeur, des troubles anxieux et des troubles connexes périnatals

BACKGROUND

The Canadian Network for Mood and Anxiety Treatments (CANMAT) publishes clinical practice guidelines for mood and anxiety disorders. This CANMAT guideline aims to provide comprehensive clinical guidance for the pregnancy and postpartum (perinatal) management of mood, anxiety and related disorders.

METHODS

CANMAT convened a core editorial group of interdisciplinary academic clinicians and persons with lived experience (PWLE), and 3 advisory panels of PWLE and perinatal health and perinatal mental health clinicians. We searched for systematic reviews of prevention and treatment interventions for perinatal depressive, bipolar, anxiety, obsessive-compulsive and post-traumatic stress disorders (January 2013-October 2023). We prioritized evidence from reviews of randomized controlled trials (RCTs), except for the perinatal safety of medications where reviews of large high-quality observational studies were prioritized due to the absence of RCT data. Targeted searches for individual studies were conducted when systematic reviews were limited or absent. Recommendations were organized by lines of treatment based on CANMAT-defined levels of evidence quality, supplemented by editorial group consensus to balance efficacy, safety, tolerability and feasibility considerations.

RESULTS

The guideline covers 10 clinical sections in a question-and-answer format that maps onto the patient care journey: case identification; organization and delivery of care; non-pharmacological (lifestyle, psychosocial, psychological), pharmacological, neuromodulation and complementary and alternative medicine interventions; high-risk clinical situations; and mental health of the father or co-parent. Equity, diversity and inclusion considerations are provided.

CONCLUSIONS

This guideline's detailed evidence-based recommendations provide clinicians with key information to promote the delivery of effective and safe perinatal mental healthcare. It is hoped that the guideline will serve as a valuable tool for clinicians in Canada and around the world to help optimize clinical outcomes in the area of perinatal mental health.

Peripartum Depression: What's New?

PURPOSE OF THE REVIEW

Peripartum depression (PPD), including both depression during pregnancy and postpartum, is the most frequent health disorder during the perinatal period. It is a significant public health issue in many countries due to its prevalence and its impact on women, as well as on their partners and offspring. Here, we will attempt to untangle the most recent studies and publications, considering what it is essential to know in 2024 about PPD as a specific perinatal issue.

RECENT FINDINGS

PPD appears to be a very heterogeneous disorder in which a complex interplay between different factors contributes to its pathophysiology. Thus, the need to enhance diagnosis and referral through a better understanding of its severity and co-morbidities has emerged as a major public health issue. Indeed, research has consistently shown that PPD negatively impacts parent-infant interactions and infants' cognitive, social, and emotional development. Evidence underlining its global risk has accumulated over the past three decades, but many questions remain, including how these vulnerable offspring developmental trajectories unfold.

Predictors of mother-infant interaction quality in women at risk of postpartum psychosis: The role of emotion recognition

BACKGROUND

Limited research exists on mother-infant interaction in women at-risk-of postpartum psychosis (PP). This study aimed to investigate potential predictors of mother-infant interaction quality in women at-risk-of-PP during the first postnatal year. Potential predictors investigated were: maternal ability to recognize emotions, childhood maltreatment, parenting stress, and infant social-interactive behaviour at birth.

METHODS

98 women (and their offspring) were included, 40 at-risk-of-PP because of a diagnosis of Bipolar Disorder, Schizoaffective Disorder or previous PP, and 58 with no current/previous mental illness or family history of PP. Mother-infant interaction was assessed using the CARE-Index at 8 weeks and 12 months postpartum. Maternal ability to recognize emotions was assessed with the VERT-K, maternal experience of childhood maltreatment with the CECA-Q, maternal parenting stress with the PSI-SF and infant social-interactive behaviour with the NBAS.

RESULTS

Women at-risk-of-PP were less able to recognize fear than healthy controls and this predicted the quality of the mother-infant interaction at 8 weeks' and 12 months' post partum, over and above the effect of maternal Group (respectively, β = 0.33, p = .015; β = 0.40, p = .006). Infant social-interactive behaviour at birth was a significant predictor for mother-infant interaction at 12 months (β = 0.32, p = .031), although this did not differ significantly between the groups.

LIMITATIONS

A relatively small sample size precluded a more in-depth investigation of indirect pathways and other potential predictors.

CONCLUSIONS

These results are important as they suggest that preventive interventions targeting emotion recognition may be implemented in women at-risk-of-PP, with the aim of improving mother-infant interaction and potentially also the infant long-term development.

Women with depression in pregnancy or a history of depression have decreased quality of mentalization in the speech to their infants

BACKGROUND

Our study aims to understand whether depression, either in pregnancy or lifetime, affects cognitive biases (comprising the attentional focus and affective state) and mentalizing features (ability to understand children's internal mental states, thereby detecting and comprehending their behavior and intention), in maternal speech during mother-infant interaction in the first postnatal year.

METHODS

We recruited 115 pregnant women (44 healthy, 46 with major depressive disorder [MDD] in pregnancy, and 25 with a history of MDD but healthy pregnancy) at 25 weeks' gestation. Three-minute videos were recorded at 8 weeks and 12 months postnatally for each dyad. Maternal speech was transcribed verbatim and coded for cognitive biases and mentalizing comments using the Parental Cognitive Attributions and Mentalization Scale (PCAMs).

RESULTS

Women suffering from antenatal depression showed a decreased proportion of mentalizing comments compared with healthy women, at both 8 weeks (0.03 ± 0.01 vs. 0.07 ± 0.01, P = 0.002) and 12 months (0.02 ± 0.01 vs. 0.04 ± 0.01, P = 0.043). Moreover, compared with healthy women, both those with antenatal depression and those with a history of depression showed decreased positive affection in speech (0.13 ± 0.01 vs. 0.07 ± 0.01 and 0.08 ± 0.02, respectively P = 0.003 and P = 0.043), and made significantly fewer comments focused on their infants' experience at 8 weeks (0.67 ± 0.03 vs. 0.53 ± 0.04 and 0.49 ± 0.05, respectively P = 0.015 and P = 0.005). In linear regression models women's socioeconomic difficulties and anxiety in pregnancy contribute to these associations, while postnatal depression did not.

CONCLUSIONS

Both antenatal depression and a lifetime history of depression are associated with a decreased quality of women's speech to their infants, as shown by less focus on their infant's experience, decreased positive affection, and less able to mentalize. Examining maternal speech to their infants in the early postnatal months may be particularly relevant to identify women who could benefit from strategies addressing these aspects of the interactive behavior and thus improve infant outcome in the context of depression.

Maternal antenatal depression, oxytocin, and infant temperament: The roles of ethnicity and adult attachment avoidance

This study examined the associations between maternal depression and oxytocin in pregnancy, caregiving sensitivity and adult attachment style, and infant temperament. One hundred and six women recruited from a public hospital antenatal clinic in Australia, and their infants completed assessments at three time points (Time 1: pregnancy; Time 2: 3-month postpartum; Time 3: 12-month postpartum). Mothers completed self-report questionnaires assessing maternal depression symptom severity at Time 1-3, adult attachment style at Time 2, and infant temperament at Time 3. At Time 1, they also provided a blood sample to assess peripheral oxytocin levels, and at Time 2, participated in a parent-child interaction session, which was later coded for caregiving behavior (sensitivity). Neither maternal depression nor lower levels of oxytocin during pregnancy predicted difficult infant temperament; rather, it was predicted by non-Caucasian ethnicity. When all other variables were free to vary, adult attachment avoidance mediated an association between maternal depression during pregnancy and difficult infant temperament. Results highlight the potential value of interventions focusing on adult attachment insecurity for pregnant women and raise questions about associations between culture/ethnicity and infant temperament.

Mother-infant interaction and infant development in women at risk of postpartum psychosis with and without a postpartum relapse

BACKGROUND

This study aimed to investigate mother-infant interaction and infant development in women at-risk of postpartum psychosis (PP), with and without a postpartum relapse.

METHODS

103 women (and their offspring) were included, 43 at-risk-of-PP because of a diagnosis of bipolar disorder, schizoaffective disorder or previous PP, and 60 with no current/previous mental illness or family history of PP. Of the at-risk women, 18 developed a psychiatric relapse within 4 weeks after delivery (AR-unwell), while 25 remained symptom-free (AR-well). Mother-infant interaction was assessed using the CARE-Index at 8 weeks' and 12 months' postpartum and infant development using the Bayley-III at 12 months' postpartum.

RESULTS

Women at-risk-of-PP as a group, regardless of whether they developed a psychiatric relapse within 4 weeks after delivery, had less synchronous mother-infant interactions and had infants with less optimal cognitive, language, motor and socio-emotional development than healthy controls. In particular, boys of at-risk women had the lowest scores in cognitive, language and motor development and in mother-infant interaction, while girls of the at-risk women had the lowest scores in socio-emotional development. The synchrony in the dyad predicted infant cognitive and language development. There was no evidence for a difference in mother-infant interaction nor in infant development between the AR-unwell and AR-well groups.

CONCLUSIONS

These results suggest that, while there is a lack of evidence that an early postpartum relapse in women at-risk-of-PP could represent a risk for the infant per se, maternal risk for PP may be associated with less optimal mother-infant interaction and infant development.

Associations between mothers' and fathers' depression and anxiety prior to birth and infant temperament trajectories over the first year of life: Evidence from diagnoses and symptom severity

BACKGROUND

Developmental shifts in infant temperament predict distal outcomes including emerging symptoms of psychopathology in childhood. Thus, it is critical to gain insight into factors that shape these developmental shifts. Although parental depression and anxiety represent strong predictors of infant temperament in cross-sectional research, few studies have examined how these factors influence temperament trajectories across infancy.

METHODS

We used latent growth curve modeling to examine whether mothers' and fathers' anxiety and depression, measured in two ways - as diagnostic status and symptom severity - serve as unique predictors of developmental shifts in infant temperament from 3 to 12 months. Participants included mothers (N = 234) and a subset of fathers (N = 142). Prior to or during pregnancy, both parents were assessed for lifetime diagnoses of depression and anxiety as well as current severity levels. Mothers rated their infants' temperament at 3, 6, and 12 months of age.

RESULTS

Mothers' depression and anxiety primarily predicted initial levels of temperament at 3 months. Controlling for mothers' symptoms, fathers' depression and anxiety largely related to temperament trajectories across infancy. Lifetime diagnoses and symptom severities were associated with distinct patterns.

LIMITATIONS

Infant temperament was assessed using a parent-report measure. Including an observational measure would provide a more comprehensive picture of the infants' functioning.

CONCLUSIONS

These results indicate that mothers' and fathers' mental health are uniquely associated with infant temperament development when measured using diagnostic status and/or symptom severity. Future studies should examine whether these temperament trajectories mediate intergenerational transmission of risk for depression and anxiety.

Coding Dyadic Behavior in Caregiver-Child Interaction from a Clinical Psychology Perspective: How Should Multiple Instruments and Outcomes Be Dealt with?

The experiences children have in the interactions with their caregivers influence their developmental outcomes. To target caregiving and optimize intervention effects, the assessment of caregiver-child interactions is highly relevant for families affected by parental mental disorders. Behavioral observation is a widely used method for assessing family dynamics, and the literature offers a wide variety of instruments with which to code such data. However, a structured overview of behavioral observation instruments (BOIs) is lacking, and the multitude of types of dyadic behaviors (DBs) assessed within each BOI are complicating their application. We aim to provide an overview of the BOIs applied to families affected by mental disorders and suggest a DB taxonomy that may be used across BOIs. We first conducted a systemic literature search to identify the most frequently used BOIs and the DBs they capture in clinical psychology. Second, we asked 13 experts to sort DB terms based on perceived conceptual similarity and analyzed these results using multidimensional scaling. We found approximately 450 different terms for DBs, and we argue that DBs can be classified within two overarching dimensions, i.e., in terms of structure and in terms of reaction to a child's signals. These efforts can facilitate the coding and application of BOIs in clinical practice.

A systematic review of clinical psychological guidance for perinatal mental health

BACKGROUND

Guidelines on psychological and/or psychosocial assessment and intervention in the perinatal period can provide beneficial practice guidance for healthcare professions to reduce maternal distress and potential mortality. As little is known about the similarities in recommendations across guidelines, which could impact the quality of therapeutic intervention women receive, this systematic review was conducted to draw out the consistent guidance for perinatal psychological and/or psychosocial therapeutic input.

METHOD

Eight literature and two guideline databases were searched alongside guideline development institutions, and organisations of maternity or perinatal mental health care. All relevant guidance was searched for and extracted before guideline quality was assessed using the AGREE-II instrument. Included guidelines had a primary or secondary focus on psychological assessment and therapeutic intervention for perinatal mental health difficulties. Using a narrative synthesis approach, recommendation consistencies and inconsistencies were outlined.

RESULTS

From the 92 records screened, seven guidelines met the inclusion criteria. Only two guidelines were rated high (> 80%) across all assessed domains, with the other guidelines scoring between poor and excellent across domains. Highest rated domains across all seven guidelines were clarity of presentation (75%) and scope and purpose (70%). Recommendations for structured psychological assessment and intervention were most commonly reported in the guidelines; however, the level of detail and depth of information varied across guidelines. Whilst assessment and intervention recommendations for mother-infant dyad and partners were considered, research into working therapeutically with these client groups in perinatal mental health services is only just emerging. Hence, guideline recommendations for working with the mother-infant dyad and partners were based on consensus of expert opinion.

CONCLUSION

Perinatal mental health guidelines were consistent in scope but showed considerable variability in quality and depth of recommendations, which could have implications for standards of clinical practice. However, there is still a need to improve the evidence underpinning recommendations in perinatal mental health guidelines to advance the implementation of psychological and/or psychosocial interventions. High quality interventions in the perinatal period could improve outcomes for women and their families.

Behavioural outcomes of children exposed to antidepressants and unmedicated depression during pregnancy

BACKGROUND

Antenatal exposure to both antidepressants and maternal depression has been associated with child behavioural difficulties. However, previous research has not adequately distinguished between the effects of the antidepressants and the underlying maternal depression.

METHODS

Child behavioural difficulties were assessed using the Strengths and Difficulties Questionnaire at 2-, 4.5-, and 8-years of age by mothers in the Growing Up in New Zealand study (N = 6233 at 2-years; N = 6066 at 4.5-years; N = 4632 at 8-years). Mothers were classified as either on antidepressants, unmedicated depression, or neither based on self-reported antidepressant intake during pregnancy and the Edinburgh Postnatal Depression Scale. Hierarchical multiple logistic regressions were used to examine whether antenatal exposure to antidepressants and unmedicated depression had a differential association with child behavioural outcomes relative to no exposure.

RESULTS

When later life depression in the mother and a range of birth and sociodemographic variables were accounted for, neither antenatal exposure to unmedicated depression or antidepressants remained associated with an increased risk of behavioural difficulties at the ages investigated. However, maternal later life depression was associated with behavioural difficulties in the fully adjusted analyses at all three ages investigated.

LIMITATIONS

The current study relied on mother-report of child behaviour which may be susceptible to bias due to maternal mental health problems.

CONCLUSIONS

Adjusted results did not show an adverse association between antenatal antidepressant exposure or unmedicated depression in relation to child behaviour. Findings also suggest that efforts to improve child behaviour need to include more family-based approaches that support maternal wellbeing.

Gestational diabetes mellitus and its impact on the mother-infant relationship: A cohort study in the postnatal period

Women with gestational diabetes mellitus (GDM) are at increased risk of poor perinatal mental health outcomes. However, the association between GDM and the mother-infant relationship is unclear. This study aimed to examine whether GDM itself impacts the mother-infant relationship and maternal mental health using a cohort study design. We used data from the Cohort of Newborns in Emilia-Romagna (CoNER) study, which included 642 women recruited in Bologna, Italy. Psychological data were collected at 6 and 15 months postnatally using a purpose designed measure to examine the mother-infant relationship. We used linear fixed effects and mixed-effects models to assess the effect of GDM on relationship scores at 6 and 15 months postpartum. Women with GDM had significantly lower relationship scores at 15 months postpartum [β - 1.75 95% CrI (-3.31; -0.21)] but not at 6 months [β - 0.27 95% CrI (-1.37; 0.81)]. Mother-infant relationship scores were significantly lower overall at 15 months compared to 6 months postpartum [β - 0.29 95% CrI (-0.56; -0.02)]. Our findings suggest that there may be a delayed effect on the mother-infant relationship in response to the experience of GDM. Future research using large birth cohorts should investigate this further to confirm these findings, and whether women with GDM would benefit from early interventions to improve relationships taking into account length of time postpartum.

Feasibility, clinical efficacy, and well-being outcomes of an online singing intervention for postnatal depression in the UK: SHAPER-PNDO, a single-arm clinical trial

BACKGROUND

Postnatal depression (PND) affects over 12% of mothers, with numbers rising during COVID-19. Singing groups can support mothers with PND; however, online delivery has never been evaluated. SHAPER-PNDO, a single-arm clinical trial, evaluated the feasibility, clinical efficacy, and well-being outcomes of a 6-week online version of Breathe Melodies for Mums (M4M) singing intervention developed for mothers with PND during COVID-19 lockdowns.

METHODS

The primary objective of this study was to assess the feasibility of a group online singing intervention for new mothers with postnatal depression. This was ascertained through recruitment rates, study retention rates, attendance rates to the singing sessions, and study completion rates. The secondary objective of the study was to assess the clinical efficacy and well-being outcomes of the singing intervention. Specifically, we measured change in Edinburgh Postnatal Depression Scale (EPDS), State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS), and Office for National Statistics Wellbeing Scale (ONS) scores from baseline to end-of-intervention (week 6); follow-up assessments were completed at weeks 3, 16, and 32. Mothers were eligible if they scored ≥10 on the baseline EPDS.

RESULTS

Eighty-seven percent of the 37 recruited mothers completed the study, attending, on average, 5 of the 6 group singing sessions. With regard to secondary outcomes, at end-of-treatment, mothers experienced significant reductions in depression (EPDS, 16.6 ± 3.7 to 11.2 ± 5.3, 95% CI [0.79,1.65]), anxiety (STAI-S, 48.4 ± 27.1 to 41.7 ± 26.8, 95% CI [4.96, 17.65]) and stress (PSS, 29.0 ± 5.7 to 19.7 ± 5.3, 95% CI [1.33, 7.07]); and, furthermore, significant improvements in life satisfaction (ONS, 50.5 ± 23.0 to 72.8 ± 11.7, 95% CI [- 39.86, - 4.64]) and feelings of worthwhileness (ONS, 51.7 ± 30.4 to 78.6 ± 15.1, 95% CI [- 52.79, - 0.85]). Reduction on the EPDS correlated with a reduction on the BDI and the STAI-S and maternal childhood maltreatment was predictive of a smaller treatment response.

CONCLUSIONS

M4M online was feasible to mothers who partook in the programme. Furthermore, M4M online supports the mental health and well-being of new mothers experiencing PND, especially when barriers to in-person treatment are present.

The impact of the second COVID-19 lockdown on anxiety and depressive symptoms in pregnant women: A case study of pregnant women in northern Italy

Background

the different lockdown phases due to COVID-19 may have negatively impacted pregnant women's mental health. Concerning antenatal stress, most studies focused more on the effect of pandemic onset than on the impact of the following phases and restrictions.

Aim

the present study aimed to assess levels of anxiety and depression in a group of Italian pregnant women during the second COVID-19 phase and possible risk factors.

Method

We recruited 156 pregnant women through our Perinatal Psychology Outpatient Clinic. We divided the sample into women recruited before the pandemic (N = 88) through a face-to-face antenatal class and pregnant women recruited during the second lockdown (Covid-19 study group) (November 2020-April 2021) through the same antenatal class via Skype (N = 68). To investigate depressive and anxiety symptoms, we administered the Edinburgh Postnatal Depression Scale (EPDS) and the State and Trait Anxiety Inventory (STAI-Y) scales; women's medical history and obstetric data were collected.

Findings

women belonging to the Covid-19 study group reported higher depressive and anxious levels than the pre-pandemic group. Moreover, during the second lockdown previous psychopathology and being close to childbirth were related to increased depression; a history of abortion was related to higher levels of trait anxiety instead.

Conclusion

recurrent restrictive measures due to COVID-19 negatively affected the antenatal mental well-being of pregnant women, particularly worsening depressive and anxious feelings. Pregnant women during the pandemic represented a vulnerable population to be monitored more closely and timely to prevent psychological problems in the postpartum period and their consequences on the child.

The vocal dialogue in 9/11 pregnant widows and their infants: Specificities of co-regulation

Mothers who were pregnant and widowed on September 11, 2001, and their 4-6-month infants (in utero on 9/11) were filmed during face-to-face interaction and their vocal dialogues were examined via microanalysis. Mothers were White, well-educated, mean age 34.3 years, and far from the World Trade Center site on 9/11; infants were 4-6 months, half female. We examined the bi-directional, moment-by-moment co-regulation of the timing of vocal dialogue, and particularly turn taking, in mother-infant and stranger-infant interactions, with time-series models. We analyzed the contingent coordination of durations of (1) vocalizations of the turn-holder, and (2) switching-pauses at the moment of the turn exchange. The switching pause is an aspect of the rhythm of the turn-holder who, after taking a turn, yields the floor to the partner through the switching pause. Turn taking is the lynchpin of dialogue, and the bi-directional contingent coordination of the switching-pause regulates the turn exchange. Both partners showed signs of risk and resilience. The 9/11 mothers did not coordinate the timing of turn taking with their infants, a highly unusual finding. In contrast, the 9/11 infants did coordinate the timing of turn taking with their mothers, and with the "stranger," forms of resilience. We propose that the 9/11 mother's difficulty coordinating with the infant's turn taking rhythm is a mode of transmission of her trauma to the infant. This work expands our knowledge of the specificities of co-regulation in the context of the 9/11 trauma.

Should Antidepressants be Avoided in Pregnancy?

Many (> 40%) women discontinue antidepressants during pregnancy because of concerns about effects on the foetus, based on information from inadequately-controlled studies. The sibling-control study design provides the best control for confounding factors, notably maternal depression. The purpose of this review was to investigate the evidence from sibling-control analyses for adverse outcomes in offspring associated with antidepressant exposure during pregnancy. Fourteen sibling-control studies were identified through searches of PubMed and Embase. Outcomes included preterm birth, small for gestational age, neonatal size, birth defects, autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), behavioural problems, neurodevelopmental deficits, and scholastic attainment. For the majority of these outcomes, no statistically significant associations were found when comparing exposed and unexposed siblings. Single studies reported associations with preterm birth, reduced gestational age, ADHD, anxiety at 36 months, and lower mathematics test scores, which persisted in the sibling-control analyses. However, differences were small and possibly not clinically significant. Moreover, effects of residual confounding could not be excluded. These findings provide evidence that many of the previously reported associations between prenatal antidepressant exposure and adverse outcomes in offspring are no longer statistically significant when exposed offspring are compared with unexposed siblings. The few statistically significant differences in sibling-control analyses were generally small with doubtful clinical significance. Decisions on antidepressant treatment during pregnancy should be made individually, based on evidence from properly controlled studies, not on misleading information based on studies that have not controlled adequately for confounding factors.

Online singing interventions for postnatal depression in times of social isolation: a feasibility study protocol for the SHAPER-PNDO single-arm trial

BACKGROUND

Postnatal depression (PND) affects 13% of new mothers, with numbers rising during the COVID-19 pandemic. Despite this prevalence, many women have difficulty with or hesitancy towards accessing pharmacological and/or psychological interventions. Group-based mother-baby activities, however, have a good uptake, with singing improving maternal mental health and the mother-infant relationship. The recent lockdowns highlight the importance of adapting activities to an online platform that is wide-reaching and accessible.

AIMS

The SHAPER-PNDO study will primarily analyse the feasibility of a 6-week online singing intervention, Melodies for Mums (M4M), for mothers with PND who are experiencing barriers to treatment. The secondary aim of the SHAPER-PNDO study will be to analyse the clinical efficacy of the 6-week M4M intervention for symptoms of postnatal depression.

METHODS

A total of 120 mothers and their babies will be recruited for this single-arm study. All dyads will attend 6 weekly online singing sessions, facilitated by Breathe Arts Health Research. Assessments will be conducted on Zoom at baseline and week 6, with follow-ups at weeks 16 and 32, and will contain interviews for demographics, mental health, and social circumstances, and biological samples will be taken for stress markers. Qualitative interviews will be undertaken to understand the experiences of women attending the sessions and the facilitators delivering them. Finally, data will be collected on recruitment, study uptake and attendance of the programme, participant retention, and acceptability of the intervention.

DISCUSSION

The SHAPER-PNDO study will focus on the feasibility, alongside the clinical efficacy, of an online delivery of M4M, available to all mothers with PND. We hope to provide a more accessible, effective treatment option for mothers with PND that can be available both during and outside of the pandemic for mothers who would otherwise struggle to attend in-person sessions, as well as to prepare for a subsequent hybrid RCT.

Immunological and other biological correlates of the impact of antenatal depression on the mother-infant relationship

Antenatal depression affects up to 20% of pregnancies, yet research has historically focused on postnatal depression and its effects on mothers and their offspring. Studies are now emerging highlighting the impact that depression in pregnancy can also carry on both members of the dyad, including difficulties with psychological, physical, and social functioning. More specifically, researchers have begun to examine whether antenatal depression may lead to difficulties in the developing mother-infant relationship and subsequent infant attachment. While much of the research on this has explored psychosocial mechanisms behind the pathway from antenatal depression to a disrupted relationship in the postpartum, few studies have looked at biological underpinnings of this process. Of the literature that exists, it has been found that mothers with depression in pregnancy have lower levels of oxytocin and increased levels of inflammatory markers, plausibly creating difficulties in the mother-infant bonding process, leading to impaired mother-infant interactions and non-secure infant attachment. Furthermore, infants with non-secure attachments are at risk of entering a proinflammatory state due to a dysregulated stress response system. Overall, the literature on the neurobiology of mother-infant interactions and infant attachment in the context of antenatal depression is sparse, thus warranting future research.

Increased maternal inflammation and poorer infant neurobehavioural competencies in women with a history of major depressive disorder from the psychiatry research and motherhood - Depression (PRAM-D) study

INTRODUCTION

Stress in pregnancy is associated with adverse outcomes in offspring, and developmental programming is a potential mechanism. We have previously shown that depression in pregnancy is a valid and clearly defined stress paradigm, and both maternal antenatal and offspring stress-related biology is affected. This study aims to clarify whether maternal biology in pregnancy and offspring outcomes can also be influenced by a history of a prior depression, in the absence of depression in pregnancy. Our primary hypothesis is that, similarly to women with depression in pregnancy, women with a history of depression but who are not depressed in pregnancy will have increased cortisol secretion and markers of immune system function, and that their offspring will have poorer neuro-developmental competencies and increased cortisol stress response.

METHODS

A prospective longitudinal design was used in 59 healthy controls and 25 women with a past history of depression who were not depressed in pregnancy, named as 'history-only', and their offspring. Maternal antenatal stress-related biology (cortisol and markers of immune system function) and offspring outcomes (gestational age at birth, neonatal neurobehaviour (Neonatal Behavioural Assessment Scale, NBAS), cortisol stress response and basal cortisol at 2 and 12 months) and cognitive, language and motor development (Bayley Scales of Infant and Toddler Development (BSID)) were measured.

RESULTS

Compared with healthy pregnant women, those with a history of depression who remain free of depression in pregnancy exhibit increased markers of immune system function in pregnancy: IL-8 (d = 0.63, p = 0.030), VEGF (d = 0.40, p = 0.008) and MCP-1 (d = 0.61, p = 0.002) and have neonates with lower neurobehavioural scores in most areas, reaching statistical significance in thesocial-interactive (d = 1.26, p = 0.015) cluster. However, there were no differences in maternal or offspring HPA axis function or in infant development at 12 months.

CONCLUSION

Our study indicates that pregnant women with a history of depression have increased markers of immune system function, and their offspring show behavioural alterations that may be the effects of in utero programming, epigenetic factors or genetic predisposition.

Major depression and generalised anxiety disorder: An analysis of the effects of remission status and comorbidity on mother-infant emotional availability in the perinatal period

BACKGROUND

The effects of maternal depression on mother-infant relationship quality likely vary according to depression heterogeneity. We investigated the effects of different presentations of major depression on mother-infant emotional availability (EA).

METHODS

Data were obtained from 115 mother-infant dyads from a longitudinal pregnancy cohort. Disorders, symptoms, and antidepressant use were assessed in pregnancy and postpartum, and EA was observed 6-month postpartum. Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) were assessed using the Structured Clinical Interview for the DSM-5. A series of multivariate analyses of covariance analyses' examining the effects of disorder on EA were conducted.

RESULTS

After controlling for maternal age, antidepressant use, and postpartum depressive symptoms, MDD accounted for 20% of the variance in EA. In the MDD/GAD group, 93% of interactions were rated as emotionally unavailable, nearly threefold the comparison group rate.

CONCLUSIONS

Findings demonstrate that different presentations of major depression are associated with observed differences in mother-infant EA.
