Early intervention to protect the mother-infant relationship following postnatal depression: study protocol for a randomised controlled trial

The cost-effectiveness of zuranolone versus selective serotonin reuptake inhibitors for the treatment of postpartum depression in the United States

AIMS

The objective of this research is to evaluate the cost-effectiveness of zuranolone, the first oral treatment indicated for postpartum depression (PPD) in adults approved by the United States Food and Drug Administration.

METHODS

Zuranolone and selective serotonin reuptake inhibitor (SSRI) trial-based efficacy was derived from an indirect treatment comparison. Long-term efficacy outcomes were based on a large longitudinal cohort study. Maternal health utility values were derived from trial-based, short-form 6-D responses. Other inputs were derived from literature and economic data from the US Bureau of Labor Statistics. We estimated costs (2023 US dollars) and quality-adjusted life-years (QALYs) for patients with PPD treated with zuranolone (14-day dosing) or SSRIs (chronic dosing). The indirect costs and QALYs of the children and partners were also estimated.

RESULTS

The incremental cost-effectiveness ratio for zuranolone versus SSRIs was $94,741 per QALY gained over an 11-year time horizon. Maternal total direct medical costs averaged $84,318 in the zuranolone arm, compared to $86,365 in the SSRI arm. Zuranolone-treated adults averaged 6.178 QALYs compared to 6.116 QALYs for the SSRI arm. Costs and utilities for the child and partner were also included in the base case. Drug and administration costs for zuranolone averaged $15,902, compared to $30 for SSRIs over the studied time horizon. Results were sensitive to the model time horizon.

LIMITATIONS

As head-to-head trials were not available to permit direct comparison, efficacy inputs were derived from an indirect treatment comparison which can be confounded by cross-trial differences. The data used are reflective of a general PPD population rather than marginalized individuals who may be at a greater risk for adverse PPD outcomes. The model likely excludes unmeasured effects for patient, child, and partner.

CONCLUSIONS

This economic model's results suggest that zuranolone is a more cost-effective therapy compared to SSRIs for treating adults with PPD.

Improving the mother-infant relationship following postnatal depression: a randomised controlled trial of a brief intervention (HUGS)

Postnatal depression (PND) disrupts the crucial mother-infant relationship on which optimal child development depends. However, few well-evaluated, brief mother-infant interaction interventions exist. This randomised controlled trial (RCT) aimed to evaluate the effect of a 4-session, group-based mother-infant interaction intervention ('HUGS'), compared to a control playgroup, both following cognitive-behavioural therapy for PND, on mother-infant relationships and early child development. It was hypothesised that dyads receiving the HUGS intervention would show larger improvements than control dyads. Mothers (n = 77; M age = 32 years) diagnosed with major or minor depressive disorder using the Structured Clinical Interview for the DSM-IV participated with their infants (<12 months). Primary outcomes were observed mother-infant interactions using the Parent Child Early Relational Assessment (ERA) and maternal parenting stress using the Parenting Stress Index (PSI). Data were collected at baseline, post-PND treatment, post-HUGS intervention and 6-month post-HUGS follow-up. Seventy-four percent of HUGS dyads attended at least half of the HUGS sessions (≥2). Significant group differences emerged at the 6-month follow-up (but were not significant immediately post-HUGS). At 6-month follow-up, HUGS dyads showed significantly improved parental positive affective involvement and verbalisation (ERA; F_{1, 47} = 4.96, p = .03, η_p² = .10) and less impaired bonding (F_{1, 45} = 4.55, p = .04, η_p² = .09) than control dyads. No differences were found on the PSI or on child development outcomes. Both groups improved substantially (around 30 points) on the PSI following PND treatment, so that average scores were below the clinically significant threshold when beginning HUGS and the control playgroup. Findings suggest that incorporating HUGS intervention following PND treatment is effective for improving mother-infant relationships. A longer-term follow-up and larger sample size may be needed for improved mother-infant relationships to show an impact on observable child developmental outcomes.

Prevention of Mental Health Difficulties for Children Aged 0-3 Years: A Review

The period of infancy and early childhood is a critical time for interventions to prevent future mental health problems. The first signs of mental health difficulties can be manifest in infancy, emphasizing the importance of understanding and identifying both protective and risk factors in pregnancy and the early postnatal period. Parents are at a higher risk of developing mental health problems during the perinatal period. An understanding of the evidence around prevention and intervention for parental anxiety and depression is vital to the process of prevention of early mental health disorders in infants and young children. Here we review the existing prevention and treatment interventions in the early years focusing on the period from conception to 3 years - the majority targeting parents in order to improve their mental health, and that of their infants. Elements of successful programs for parents include psychoeducation and practical skills training, as well as work on the co-parenting relationship, developing secure attachment, and enhancing parental reflective functioning. While both targeted and universal programs have produced strong effect sizes, universal programs have the added benefit of reaching people who may otherwise not have sought treatment. In synthesizing this information, our goal is to inform the development of integrated models for prevention and novel early intervention programs as early in life as possible.

Weight Stigma across the Preconception, Pregnancy, and Postpartum Periods: A Narrative Review and Conceptual Model

Weight stigma is a pervasive issue promoting significant adverse health and psychosocial consequences. Preconception, pregnant, and postpartum women are particularly vulnerable to weight stigma, which can directly impact their health and that of the next generation. Of note, weight stigma affects women living with obesity who are already at risk for developing gestational diabetes and experiencing associated stigmas. This narrative review aimed to examine the literature on weight stigma across the preconception, pregnancy, and postpartum periods, specifically to (1) synthesize the evidence using a socioecological lens; (2) develop a conceptual model of weight stigma tailored to women across this life phase; and (3) provide recommendations for future research. To date, weight stigma research across the preconception, pregnancy, and postpartum periods has focused predominately on pregnancy and antenatal care. The drivers and facilitators of this stigma are pervasive, occurring across various contexts and settings. Manifestations of weight stigma include decreased reproductive healthcare quality, mental health symptoms, poorer health behaviors, and adverse pregnancy outcomes. Future research should further investigate the experiences of women preconception and postpartum, and health/social impacts beyond healthcare. The model herein will guide such research to ultimately identify opportunities for stigma reduction and improve multigenerational health and well-being outcomes.

A qualitative insight into the relationship between postpartum depression and body image

Objective: This study qualitatively explored the experience of depression and body image concerns in women diagnosed with depression in the postpartum period.Background: Women's bodies undergo substantial changes during the perinatal period which can impact their body image and mood post-birth.However, it remains unknown how women diagnosed with depression experience their body image in the postpartum period.Methods: Seventeen women in their firstpostpartumyear completed qualitative telephone interviews: seven women diagnosed with depression and ten without depression. Thematic content analysis identified the main themes of the women's narratives: 1) expectations and adjustments to motherhood; 2) mood in response to changing postpartum body; 3) the context of feeling bad about my body; and 4) body letting me down and relationship to mood.Results: Differences in the relationship between body image and mood for postpartum women with depression compared to women without depression were revealed. Other themes seemed to be experienced in the same way by women with and without depression.Conclusion: Poor body image and depressive symptoms appear linked during postpartum. An improved understanding of this association may assist postpartum women to manage negative body image post-birthand prevent the exacerbation of negative emotional health in this period.

Lifestyle and Psychological Factors Associated with Pregnancy Intentions: Findings from a Longitudinal Cohort Study of Australian Women

BACKGROUND

Preconception is a critical time for the establishment of healthy lifestyle behaviours and psychological well-being to reduce adverse maternal and offspring outcomes. This study aimed to explore relationships between preconception lifestyle and psychological factors and prospectively assessed short- (currently trying to conceive) and long-term (future parenthood aspirations) pregnancy intentions.

METHODS

Data from Wave 3 (age 25-30 years; n = 7656) and Wave 5 (age 31-36 years; n = 4735) from the Australian Longitudinal Study of Women's Health were used. Pregnancy intentions and parenthood aspirations were evaluated. Logistic regressions explored cross-sectional associations between demographic, lifestyle and psychological factors and pregnancy intentions/parenthood aspirations.

RESULTS

In multivariable models, parity and marital status were associated consistently with pregnancy intentions and parenthood aspirations. Few lifestyle behaviours and no psychological factors were associated with pregnancy intentions. Alcohol intake was the only behaviour associated with aspirations to have a first child. Aspirations for a second/subsequent child were associated negatively with physical activity, sitting time, diet quality, lower anxiety and higher stress.

CONCLUSIONS

It appears that women are not changing their behaviours when they form a decision to try to conceive. Interventions are needed that address women's preconception needs, to optimise lifestyle and improve health outcomes for women and their families.

Maternal body dissatisfaction in pregnancy, postpartum and early parenting: An overlooked factor implicated in maternal and childhood obesity risk

BACKGROUND

Current evidence indicates that to prevent the intergenerational transfer of overweight and obesity from parent to child, interventions are needed across the early life stages, from preconception to early childhood. Maternal body image is an important but often overlooked factor that is potentially implicated in both short- and long-term maternal and child health outcomes, including maternal gestational weight gain, postpartum weight retention, obesity, child feeding practices and early parenting.

AIM

The aim of this paper is to propose a conceptual model of the relationship between maternal body image (with a specific focus on body dissatisfaction) and maternal and child excess body weight risk across the pregnancy, postpartum and early childhood periods, as well as to highlight opportunities for intervention.

CONCLUSION

Our conceptual model proposes factors that mediate the associations between antenatal and postpartum maternal body dissatisfaction and maternal and childhood obesity risk. Pregnancy and postpartum present key risk periods for excess weight gain/retention and body dissatisfaction. Psychosocial factors associated with maternal body dissatisfaction, including psychopathology and disordered eating behaviours, may increase maternal and child obesity risk as well as compromise the quality of mother-child interactions underpinning child development outcomes, including physical weight gain. Our conceptual model may be useful for understanding modifiable psychosocial factors for preventing the intergenerational transfer of obesity risk from mothers to their children, from as early as pregnancy, and highlights next steps for multidisciplinary research focused on combatting maternal and child obesity during critical risk periods.

Early mother-child dyadic pathways to childhood obesity risk: A conceptual model

Understanding the emotional quality of the mother-child dyadic relationship and parent-child feeding interactions may further clarify early developmental pathways to eating behaviours and obesity risk. The quality of parent-child relationships fosters all aspects of child development but has not yet been extensively examined in relation to childhood weight gain. The aim of this paper is to propose a conceptual model, which outlines early mother-child dyadic pathways linking parent-child feeding interactions to child body mass index, where parent-child relationships have a central role. It maps out individual and dyadic mother-child factors (i.e., attachment, child temperament and maternal mental health) that influence the nature and quality of parent-child feeding interactions from infancy to toddlerhood. Our model bridges the gap between research fields by bringing together key maternal and child factors implicated in child development. Understanding early parent-child feeding interactional patterns and their influence on child self-regulation and eating behaviours may be relevant to multidisciplinary approaches toward preventing childhood obesity. High quality quantitative and observational data capturing meaningful parent, child and dyadic level interactions around food contexts, attachment security, maternal mental health, child temperament and self-regulation will help to inform new, aetiologically important, targets for preventative intervention.

Cumulative risk factors and mental health of mothers of infants admitted to the neonatal intensive care unit

Purpose: The present study examined predictive linkages between multiple risk factors and their contribution to the development of anxiety and depression in Puerto Rican mothers of infants admitted to the Neonatal Intensive Care Unit (NICU).Method: The scales used were: the Hamilton Anxiety Rating Scale, the Edinburgh Postpartum Depression Scale, the Hollingshead, and a Demographic Questionnaire was constructed to obtain information about mother and infant characteristics.Results: Both the cumulative psychosocial risk factor (B = 0.267, p = .011) and the cumulative neonatal risk factor (B = -0.220, p = .039) were significant predictors of mothers' anxiety.Discussion: It could be beneficial to create psychosocial interventions in the NICU to address parents' needs and promote emotional resilience. Also, training staff to provide an adequate explanation to mothers, regarding the infants' recovery process is of particular importance.

Establishing a coherent and replicable measurement model of the Edinburgh Postnatal Depression Scale

The 10-item Edinburgh Postnatal Depression Scale (EPDS) is an established screening tool for postnatal depression. Inconsistent findings in factor structure and replication difficulties have limited the scope of development of the measure as a multi-dimensional tool. The current investigation sought to robustly determine the underlying factor structure of the EPDS and the replicability and stability of the most plausible model identified. A between-subjects design was used. EPDS data were collected postpartum from two independent cohorts using identical data capture methods. Datasets were examined with confirmatory factor analysis, model invariance testing and systematic evaluation of relational and internal aspects of the measure. Participants were two samples of postpartum women in England assessed at three months (n = 245) and six months (n = 217). The findings showed a three-factor seven-item model of the EPDS offered an excellent fit to the data, and was observed to be replicable in both datasets and invariant as a function of time point of assessment. Some EPDS sub-scale scores were significantly higher at six months. The EPDS is multi-dimensional and a robust measurement model comprises three factors that are replicable. The potential utility of the sub-scale components identified requires further research to identify a role in contemporary screening practice.

Introduction of iodised salt benefits infants’ mental development in a community-based cluster-randomised effectiveness trial in Ethiopia

The effectiveness of salt iodisation in improving the mental development of young children has not been assessed. We implemented a community-based cluster-randomised effectiveness trial in sixty randomly selected districts in the Amhara region of Ethiopia. We randomly allocated each district to treatment and randomly selected one of its villages. In parallel to national salt iodisation efforts, iodised salt was brought early into the markets of the thirty intervention villages before it became widely available in the thirty control villages 4–6 months later. The primary outcome was children’s mental development scores on the Bayley Scales. This was an intention-to-treat analysis using mixed linear models adjusted for covariates and clusters. The trial was registered at ClinicalTrials.gov, NCT013496. We assessed 1835 infants aged 5–11 months at baseline. The same children (85 % of the sample) were re-assessed at 20–29 months when all villages had iodised salt. At endline, urinary iodine concentration was higher in children in the intervention group compared with those in the control group (median 228·0v. 155·1 µg/l,P=0·001). The intervention group had higher scores compared with the control group on the Bayley composite score (raw scores:130·60v. 128·51; standardised scores: 27·8v. 26·9;d=0·13; 95 % CI 0·02, 0·23) and three of the four subscales: cognitive (53·27v. 52·54,d=0·13; 95 % CI 0·03, 0·23), receptive language (20·71v. 20·18,d=0·13; 95 % CI 0·03, 0·24) and fine motor (35·45v. 34·94,d=0·15; 95 % CI 0·04, 0·25). The introduction of iodised salt contributes to children’s higher urinary iodine concentration and mental development.

Development and preliminary evaluation of a group intervention targeting maternal mental health and mother-infant interactions: a combined qualitative and case series report

OBJECTIVE AND BACKGROUND

The purpose of this study was to investigate the outcomes of an Emotional Wellbeing Group intervention developed to treat maternal depression and anxiety while concurrently supporting positive development of the mother-infant relationship.

METHOD

Five women diagnosed with depressive and/or anxiety disorders and their infants completed the Emotional Wellbeing Group. The participants completed pre- and post- intervention assessments which included self-report measures of mood and the motherhood experience, and a video-taped, unstructured play session between mothers and their infants.

RESULTS

Four of the participants reported a clinically significant decrease in their symptoms of anxiety. All mothers reported more positive perceptions of their infants and their experience of motherhood, and showed enhanced maternal sensitivity and responsiveness towards their infants. Depression levels were not shown to improve consistently.

CONCLUSION

This study provides initial positive evidence to support future research directions and clinical efforts to develop interventions that target both the treatment of perinatal depression and anxiety and the quality of mother-infant interactions. Clinical insights for mental health professionals working with mothers and infants are presented.

Perinatal depression: A clinical update

Perinatal depression is a common condition with significant adverse maternal, fetal, neonatal, and early childhood outcomes. The perinatal period is an opportune time to screen, diagnose, and treat depression. Improved recognition of perinatal depression, particularly among low-income women, can lead to improved perinatal health outcomes.

The associations between depressive and anxiety symptoms, body image, and weight in the first year postpartum: a rapid systematic review

OBJECTIVE

The aim of this study was to conduct a rapid systematic review of the evidence of associations between postpartum depressive symptoms, anxiety symptoms, body image and weight status in the first 12 months post birth.

BACKGROUND

The postpartum period places the mother and infant at risk of a number of negative health outcomes. Mental health conditions such as depression and anxiety are common in the postpartum, as are poor body image and excessive weight retention as women adjust to their post pregnancy body. However, the associations between body image, weight status and psychological distress are not currently well understood.

METHODS

Articles in English, published between 2006 and 2017, involving singleton pregnancies of normally developing infants and maternal depression or anxiety were eligible for this systematic review.

RESULTS

From the total of 1805 articles located, 12 were identified as relevant and were subsequently reviewed in full. In the nine studies of depressive symptoms, body image or weight status, four found a significant relationship. Significant associations were not found in the three studies investigating postpartum anxiety symptoms, body image or weight. Body dissatisfaction was associated significantly with poorer postpartum weight status in all nine studies.

CONCLUSIONS

Further research is needed to determine the nature of the relationships between body image, weight status and depressive and anxiety symptoms across the first year after birth. This information will assist health professionals to promote healthy lifestyle behaviours in the postpartum, as well as inform clinical interventions that target behaviour change to prevent the worsening of these issues and related negative outcomes.

Attachment security mediates the longitudinal association between child-parent psychotherapy and peer relations for toddlers of depressed mothers

Numerous investigations have demonstrated that child-parent psychotherapy (CPP) promotes secure attachment between mothers and offspring. However, the role of postintervention attachment security as it relates to long-term child outcomes has never been evaluated. The present study therefore examined postintervention attachment status as a mediator of the association between CPP for depressed mothers and their offspring and subsequent peer relations among offspring. Depressed mothers and their toddlers were randomized to receive CPP (n = 45) or to a control group (n = 55). A prior investigation with this sample indicated that offspring who received CPP attained significantly higher rates of secure attachment postintervention, whereas insecure attachment continued to predominate for offspring in the control group. The present study examined follow-up data of teachers' reports on participants' competence with classroom peers when they were approximately 9 years old. Findings indicated that children who received CPP were more likely to evidence secure attachments at postintervention, which in turn was associated with more positive peer relationships at age 9.

Path Analysis Association between Domestic Violence, Anxiety, Depression and Perceived Stress in Mothers and Children's Development

OBJECTIVE

Given that several factors involved in the incidence or exacerbation of developmental disorders in children, the present study aimed to investigate the relationship between some of the risk factors affecting mothers' health and development in children using path analysis.

MATERIALS & METHODS

The present cross-sectional analytical study was conducted on 750 mothers and their children in health centers in Tehran, Iran in 2014 enrolled through multi-stage random sampling. Data were collected using a demographic and personal information questionnaire, the Perceived Stress Scale, Beck's depression Inventory, Spielberger' anxiety inventory, the WHO domestic violence questionnaire and an ages & stages questionnaire for assessing children's development. Data were analyzed using SPSS.19 (Chicago, IL, USA) and Lisrel 8.8.

RESULTS

Developmental delay was observed in 12.1% of the children. The mean stress score was 23.94±8.62 in the mothers, 50.7% of whom showed mild to severe depression, 84.2% moderate to severe anxiety and 35.3% had been subjected to domestic violence. The path analysis showed that children's development was affected directly by perceived stress (β=-0.09) and depression (β=-0.17) and indirectly by domestic violence (β=-0.05278) and anxiety (β=-0.0357). Of all the variables examined, depression had the biggest influence on development in the children (β=-0.17). The proposed model showed a good fit (GFI=1, RMSEA=0.034).

CONCLUSION

Children's development was influenced indirectly by domestic violence and anxiety and directly by perceived stress and depression in mothers. It is thus suggested that more concern and attention be paid to women's mental health and the domestic violence they experience.

The effectiveness of the Incredible Years™ Parents and Babies Program as a universal prevention intervention for parents of infants in Denmark: study protocol for a pilot randomized controlled trial

BACKGROUND

Infancy is an important period in a child's life, with rapid growth and development. Early experiences shape the developing brain, and adverse experiences can have both an immediate and lifelong impact on health and wellbeing. Parenting interventions offered to parents of newborns can support parents in providing sensitive and responsive care, and reinforce healthy development for their infants. This study aims to evaluate the impact of the Incredible Years™ Parents and Babies Program in a universal setting for parents with infants.

METHODS/DESIGN

This is a pragmatic, two-arm, parallel, pilot, randomized controlled trial (RCT) where 128 families with newborn infants up to four-months-old are recruited in two municipalities in Denmark. Families are randomized to the Incredible Years Parents and Babies Program or usual care with a 2:1 allocation ratio. The primary outcome is parenting confidence measured after 20 weeks by the Karitane Parenting Confidence Scale and Parental Stress Scale. Secondary outcomes include measures of parent health, reflective functioning, relationship with the infant, and infant development. Interviewers and data analysts are blind to allocation status.

DISCUSSION

This is the first RCT of the Incredible Years Parents and Babies Program, and one of the first rigorous evaluations of a universally offered preventive intervention for parents with infants. The trial will provide important information on the effectiveness of a relatively brief, universally offered parenting intervention for parents of infants, and will also provide information on infant measures, parent recruitment and participation, and implementation of the program, which could inform future trials.

TRIAL REGISTRATION

This trial was registered with Clinicaltrials.gov (identifier: NCT01931917) on 27 August 2013.
