The effects of preterm birth on mother-infant interaction and attachment during the infant's first two years

Effects of early intervention on the mental wellbeing and caregiving practices of preterm infant caregivers

BACKGROUND

The rising incidence of preterm births worldwide presents a pressing public health challenge, affecting both infants and their preterm caregivers. Early Intervention (EI) programs aim to mitigate the negative impacts associated with preterm births on the physical, cognitive, and psychological health of both infants and their caregivers by providing personalized parental support and developmental monitoring. This study addressed the gap in research evaluating the long-term effects of community-based EI programs on the holistic coping mechanisms of families, encompassing mental wellbeing, caregiving competencies, and the transition process from hospital to home care.

METHODS

This study evaluated the long-term effects of a community-based EI program (in-home only) and the added benefits of earlier Hospital-to-Home (H2H) support, focusing on preterm caregivers' mental wellbeing and caregiving practices.

RESULTS

The findings highlight the extended benefits of EI, demonstrating that program duration and intensity significantly benefit families dealing with neonatal intensive care unit stays. For infants requiring extensive medical intervention, EI support markedly enhances caregiver mental wellbeing. Additionally, interventions initiated earlier yield a more substantial positive effect on preterm caregivers' mental wellbeing after discharge compared to those that commence later.

CONCLUSION

These findings suggest the potential role of community-based EI programs and the benefits of supporting preterm caregivers before transitioning home. The study calls for future research to explore the effects of various EI program components to identify which interventions are most effective for addressing preterm infants' specific developmental challenges.

Early psychosocial parent-infant interventions and parent-infant relationships after preterm birth-a scoping review

Objective

Early psychosocial interventions for preterm infants and their parents are diverse. This study aimed to structure the knowledge on psychosocial parent-infant interventions and to identify gaps in the intervention studies.

Methods

We included studies on early (during first year of life) psychosocial parent-infant interventions with parent-infant relationship outcomes after preterm birth (< 37 weeks). We excluded studies that did not focus on preterm infants, failed to indicate the studied intervention and outcomes, were not written in English, were not controlled or peer-reviewed studies, or did not provide essential information for eligibility. The search included studies published between January 2000 and March 2024 in PubMed and PsycINFO. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in reporting. Psychosocial parent-infant intervention studies were classified adapting the International Classification of Health Interventions (ICHI) and the Template for Intervention Description and Replication (TIDieR).

Results

The included 22 studies reported data from 18 different interventions with preterm infants (< 37 weeks). Studies excluded preterm infants with health risks (19/22, 86%), with very low gestational age and/or birth weight (7/22, 32%), and/or mothers with psychosocial risks (14/22, 64%). Of the 18 interventions, 12 (67%) were classified as counseling, 3 (17%) as emotional support, 2 (11%) as psychotherapeutic, and 1 (6%) as educational. The parent-child relationship was assessed using 30 different methods and varying time points up to 18 months of age. Most studies (17/22, 77%) reported positive changes in the parent-child relationship favoring the intervention group.

Conclusion

We identified four types of interventions to influence parenting behavior; the most used was counseling. All four intervention types showed positive effects on parent-infant relationships, although the preterm populations studied were selective, the effects were evaluated using different methods, and the follow-up periods were short. These findings indicate a need for studies with standardized methods, longer follow-up, and less-restricted preterm populations to develop guidelines for all families with preterm infants.

Within- and between-twin comparisons of risk for childhood behavioral difficulties after preterm birth

BACKGROUND

Preterm birth and multiple gestation are independently associated with adverse neurodevelopmental outcomes. The objective of this study was to describe risks of screening positive for attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and anxiety in preterm-born twin children by zygosity (monozygotic, dizygotic) and birth order (first-born, second-born).

METHODS

Caregivers of 349 preterm-born twin pairs (42% monozygotic) aged 3-18 years reported child behavioral outcomes on Strengths and Weaknesses of ADHD Symptoms and Normal Behavior; Social Responsiveness Scale, Second Edition; and Preschool Anxiety Scale or Screen for Child Anxiety and Related Emotional Disorders.

RESULTS

Concordance for behavioral outcomes in twin pairs ranged from 80.06 to 89.31% for ADHD, 61.01 to 84.23% for ASD, and 64.76 to 73.35% for anxiety. Monozygotic twins had a greater risk than dizygotic of screening positive for inattention (risk ratio = 2.91, 95% CI = 1.48-5.72) and social anxiety (1.79, 1.23-2.61). Relative to first-born, second-born twins had a greater risk of screening positive for hyperactivity/impulsivity (1.51, 1.06-2.16); overall ASD (2.38, 1.62-3.49); difficulties with social awareness (2.68, 1.94-3.71), social cognition (4.45, 3.06-6.46), and social communication (2.36, 1.56-3.57); restricted/repetitive behavior (1.91, 1.30-2.81); overall anxiety (1.34, 1.10-1.64); generalized anxiety (1.34, 1.11-1.60); and social anxiety (1.32, 1.06-1.64).

CONCLUSION

The current findings emphasize considering zygosity and birth order in preterm and multiple birth outcomes research, and highlight clinical implications for discharge planning, neurodevelopmental surveillance, and facilitating parenting and family support.

IMPACT

Zygosity and birth order are important determinants of behavioral and socioemotional outcomes in preterm-born twins. Among 349 preterm-born twin pairs aged 3-18 years (42% monozygotic), 61-89% demonstrated concordance for behavioral and socioemotional outcomes. Monozygosity had greater risks than dizygosity for positive screening of inattention and social anxiety. Second-born twins had greater risks than first-born for hyperactivity/impulsivity, social difficulties (awareness, cognition, communication), restricted/repetitive behavior, and anxiety (generalized, social). These findings have implications for discharge planning, neurodevelopmental surveillance, and facilitating parenting and family support.

Parental stress and mental health outcomes following very preterm birth: A systematic review of recent findings

BACKGROUND

In recent years, there has been a wide array of research studies published on parental mental health and stress following very preterm birth. This review aims at reviewing the prevalence and risk factors of long-term parental depression, anxiety, post-traumatic stress symptoms and parenting stress following very preterm birth.

METHODS

We searched PubMed, PsychINFO and Web of Science for descriptive, cross-sectional and longitudinal studies published between January 2013 and August 2022.

RESULTS

45 studies met our inclusion criteria. In the first two years, depression, anxiety, post-traumatic stress symptoms and parenting stress were present in ∼20 % of mothers of extreme and very low birth weight (E/VLBW) infants. Long-term psychological distress symptoms could be observed, although few studies have focused on symptoms into school age and longer. Fathers of VLBW infants might experience more psychological distress as well, however, they were only included in ten studies. We found that parental distress is more common when the co-parent is struggling with mental health symptoms. Many risk factors were identified such as social risk, history of mental illness, interpersonal factors (i.e. social support) and child-related factors (i.e. intraventricular hemorrhage, disability, use of medical equipment at home).

LIMITATIONS

Several studies have methodological issues, such as a lack of control of known confounders and there is a large variety of measures employed.

CONCLUSION

Important risk factors for stress and mental health symptoms were identified. More evidence is needed to determine if long-term symptoms persist into school age. Research should focus on taking a family-based approach in order to identify preventive strategies and resilience factors in parents of VLBW infants.

Masked or not, I smile to you: Exploring full-term and preterm infants' social smiles to adults wearing a protective facemask

The early emergence of social smiles is an important milestone of infants' socio-emotional development. Our aim was to assess how the use of protective facemasks by adults affects the display of social smiles in preterm (PT) and full-term (FT) infants at 3 months (corrected age for prematurity). We enrolled 30 FT and 30 PT infants (gestational age ≤ 32 weeks). Infants' social smiles displays were assessed at 2-3-month-age (corrected) across a three-episode (masked mother; unmasked mother; masked adult female stranger) videotaped interactive task. During each episode, the adult was instructed to maintain specific facial expressions (happy-smiling, sad-frowning, neutral-unresponsive) for 15 second windows and then instructed to interact spontaneously for 45 s (of which the first 15 s were coded). FT and PT infants did not differ in the display of social smiles. In both groups, social smiles were mostly exhibited in response to happy/smiling and spontaneously interacting partners. Overall, no effect of wearing a protective facemask emerged. The use of protective facemasks did not result in a lower display of social smiles. The findings suggest that FT and PT might be equally sensitive to their adult interactive partners in terms of social smiles displays at 2-3-month-age.

Infant attachment does not depend on neonatal amygdala and hippocampal structure and connectivity

Infant attachment is an antecedent of later socioemotional abilities, which can be adversely affected by preterm birth. The structural integrity of amygdalae and hippocampi may subserve attachment in infancy. We aimed to investigate associations between neonatal amygdalae and hippocampi structure and their whole-brain connections and attachment behaviours at nine months of age in a sample of infants enriched for preterm birth. In 133 neonates (median gestational age 32 weeks, range 22.14-42.14), we calculated measures of amygdala and hippocampal structure (volume, fractional anisotropy, mean diffusivity, neurite dispersion index, orientation dispersion index) and structural connectivity, and coded attachment behaviours (distress, fretfulness, attentiveness to caregiver) from responses to the Still-Face Paradigm at nine months. After multiple comparisons correction, there were no significant associations between neonatal amygdala or hippocampal structure and structural connectivity and attachment behaviours: standardised β values - 0.23 to 0.18, adjusted p-values > 0.40. Findings indicate that the neural basis of infant attachment in term and preterm infants is not contingent on the structure or connectivity of the amygdalae and hippocampi in the neonatal period, which implies that it is more widely distributed in early life and or that network specialisation takes place in the months after hospital discharge.

Exploring early life social and executive function development in infants and risk for autism: a prospective cohort study protocol of NICU graduates and infants at risk for cerebral palsy

BACKGROUND

Delays in early social and executive function are predictive of later developmental delays and eventual neurodevelopmental diagnoses. There is limited research examining such markers in the first year of life. High-risk infant groups commonly present with a range of neurodevelopmental challenges, including social and executive function delays, and show higher rates of autism diagnoses later in life. For example, it has been estimated that up to 30% of infants diagnosed with cerebral palsy (CP) will go on to be diagnosed with autism later in life.

METHODS

This article presents a protocol of a prospective longitudinal study. The primary aim of this study is to identify early life markers of delay in social and executive function in high-risk infants at the earliest point in time, and to explore how these markers may relate to the increased risk for social and executive delay, and risk of autism, later in life. High-risk infants will include Neonatal Intensive Care Unit (NICU) graduates, who are most commonly admitted for premature birth and/or cardiovascular problems. In addition, we will include infants with, or at risk for, CP. This prospective study will recruit 100 high-risk infants at the age of 3-12 months old and will track social and executive function across the first 2 years of their life, when infants are 3-7, 8-12, 18 and 24 months old. A multi-modal approach will be adopted by tracking the early development of social and executive function using behavioural, neurobiological, and caregiver-reported everyday functioning markers. Data will be analysed to assess the relationship between the early markers, measured from as early as 3-7 months of age, and the social and executive function as well as the autism outcomes measured at 24 months.

DISCUSSION

This study has the potential to promote the earliest detection and intervention opportunities for social and executive function difficulties as well as risk for autism in NICU graduates and/or infants with, or at risk for, CP. The findings of this study will also expand our understanding of the early emergence of autism across a wider range of at-risk groups.

Preterm toddlers' joint attention characteristics during dyadic interactions with their mothers and fathers compared to full-term toddlers at age 2 years

The current study investigates Joint Attention (JA) characteristics (duration, frequency, source of initiation, type of JA, agent of termination, missed and unsuccessful episodes) in preterm and full-term toddlers' interactions with their mothers and fathers, separately. Thirty-one singleton full-term (Mage = 24.07 months, SD = 1.45; 13 boys) and 17 singleton preterm toddlers (Madjustedage = 24.72 months, SD = 3.39; 12 boys) participated in the study with both parents. JA episodes were examined during dyadic five-minute free play sessions, were coded second-by-second, and were analysed using two-way mixed ANOVAs. Although the total amount of time spent in JA was not significantly different between the preterm and the full-term groups, JA episodes were more frequent, specifically supported JA episodes, and were more often terminated by the child during parent-preterm toddler interactions. Moreover, preterm toddlers missed their fathers' attempts for JA more often than their mothers' and more often than full-term toddlers missed their fathers' and mothers' bids for JA. Further, regardless of the birth status, toddlers initiated more JA with mothers than fathers, and fathers redirected their child's attention to initiate JA more than mothers. Findings indicate that preterm toddlers may struggle to respond to JA bids, especially with their fathers, and to sustain their attention on a specific object or event during interactions. Preterm toddlers may need more support to engage in JA relative to their full-term peers, and redirecting attention strategy may not be optimal for them. Also, toddlers' JA interactions may be different with their mothers and fathers. Findings contribute to the literature by demonstrating preterm toddlers' JA characteristics with both parents compared to full-term toddlers at age two.

Infant-Directed Speech to Preterm Infants during the First Year Postpartum: The Influence of Preterm Birth Weight and Maternal Parenting Stress

Premature birth can increase the level of parenting stress (PS), especially in the case of parents of high-risk infants (extremely low birth weight (ELBW) and very low birth weight (VLBW)). Though published research has explored how maternal PS influences early dyadic interactions, limited research has focused on infant-directed speech (IDS), and no studies have investigated the link between prematurity severity based on birth weight and maternal IDS. This study, involving 100 mother-infant dyads, categorized into 30 ELBW premature infants, 30 VLBW premature infants, and 40 full-term (FT) ones, examined the impact of preterm birth weight and maternal parenting stress on IDS features during early interactions at 3 and 9 months postpartum. Maternal input was assessed using the CHILDES system, while parenting stress was evaluated using the Parenting Stress Index-Short Form. The results revealed that high-risk conditions (ELBW preterm birth and high parenting stress) at 3 months were associated with reduced affect-salient speech and increased questioning. IDS functional patterns, specifically the proportion of affect-salient speech and questions, were influenced by both birth weight groups and parenting stress levels at 3 months but not at 9 months. These findings highlight the need to assess, within the context of prematurity, both birth weight and parenting stress in clinical practice, offering insights for developing interventions supporting positive parent-infant interactions and facilitating infant development.

Towards Preventative Psychiatry: Concurrent and Longitudinal Predictors of Postnatal Maternal-Infant Bonding

Maternal-infant bonding is important for children's positive development. Poor maternal-infant bonding is a risk factor for negative mother and infant outcomes. Although researchers have examined individual predictors of maternal-infant bonding, studies typically do not examine several concurrent and longitudinal predictors within the same model. This study aimed to evaluate the unique and combined predictive power of cross-sectional and longitudinal predictors of maternal-infant bonding. Participants were 372 pregnant women recruited from an Australian hospital. Data were collected from mothers at antenatal appointments (T0), following their child's birth (T1), and at a laboratory assessment when their child was 5-11-months-old (T2). Poorer bonding at T2 was predicted at T0 by younger maternal age, higher education, and higher antenatal depressive symptoms. Poorer bonding at T2 was predicted at T1 by younger maternal age, higher education, and higher postnatal depressive symptoms. Poorer bonding at T2 was predicted at T2 by younger maternal age, higher education, higher postnatal depression symptoms, higher concurrent perceived social support, and more difficult infant temperament, when controlling for child age at T2. To promote positive maternal-infant bonding, global and targeted interventions in the perinatal period may benefit from targeting maternal psychopathology, perceived lack of social support, and coping with difficult infant temperament.

Infantile atopic dermatitis and maternal-infant bonding: a mixed methods study

BACKGROUND

Childhood atopic dermatitis can have a negative effect on caregivers' quality of life and stress levels due to the burdensome nature of its treatment. Given that the condition often emerges in infancy, atopic dermatitis-related stress also carries the potential to negatively affect the developing mother-infant bond. While it is plausible that atopic dermatitis has a negative impact on maternal-infant bonding, these relationships have not been studied directly. In light of this gap, the current study investigated the association between infantile atopic dermatitis and the maternal-infant bond using a mixed-method design.

METHODS

Mothers of infants (< 19 months) with atopic dermatitis were recruited from social media and medical clinics between October 2021 and May 2022. Mothers with infants unaffected by inflammatory skin conditions were also recruited to serve as a control group. Participants were asked to complete questionnaires related to their demographics, child's health, and mother-infant bond. Multiple linear regression analyses were used to assess bonding quality among cases and controls. A subset of cases were also asked to participate in semi-structured interviews focused on infantile atopic dermatitis and the maternal-infant bond.

RESULTS

The final sample consisted of 32 cases and 65 controls. Scores on the impaired bonding and risk of abuse subscales did not significantly differ between cases and controls. However, mothers of infants with atopic dermatitis did report lower levels of caregiving anxiety (b = - 1.47, p < 0.01) and pathological anger/rejection (b = - 1.74, p = 0.02) relative to controls. Qualitative findings suggest that the topical therapies required to manage atopic dermatitis may strengthen the bond between some mothers and infants.

CONCLUSION

Findings suggest that atopic dermatitis does not have a negative impact on maternal-infant bonding and may actually improve bonds in some cases. In light of this finding, clinicians may leverage the potentially positive impact of atopic dermatitis-related caregiving on the maternal-infant bond to encourage caregivers to remain adherent to their child's topical treatments.

Father's perceptions and care involvement for their very preterm infants at French neonatal intensive care units

Objectives

We aimed to evaluate (1) fathers' perceptions and care involvement for their very premature infants and their views of the hospitalization period based on parental reports and (2) their evolution over time.

Methods

We used an online parental survey to assess answers from parents of very preterm infants who were successfully discharged from French neonatal units. We analysed answers from February 2014 to January 2019 to an anonymous internet-based survey from the GREEN committee of the French Neonatal Society. Responses were compared for period 1 (P1, 1998 to 2013) and period 2 (P2, 2014 to 2019).

Results

We analyzed 2,483 surveys, 124 (5%) from fathers and 2,359 (95%) from mothers. At birth, 1,845 (80%) fathers were present in the hospital, but only 879 (38%) were near the mother. The presence of fathers in the NICU increased from P1 to P2 (34.5% vs. 43.1%, p = 0.03). Nearly two thirds of fathers accompanied their infants during transfer to the NICU (1,204 fathers, 60.6%). Fathers and mothers had similar perceptions regarding relationships with caregivers and skin-to-skin contact with their infants. However, more fathers than mothers felt welcome in the NICU and in care involvement regarding requests for their wishes when they met their infant (79% vs. 60%, p = 0.02) and in the presentation of the NICU (91% vs. 76%; p = 0.03). Mothers and fathers significantly differed in the caring procedures they performed (p = 0.01), procedures they did not perform but wanted to perform (p < 0.001), and procedures they did not perform and did not want to perform (p < 0.01).

Conclusion

Most fathers were present at the births of their very preterm infants, but fewer fathers were near the mother at this time. Less than two thirds of fathers accompanied their infants to the NICU. There should be further changes to better meet the specific needs of the fathers of infants requiring care in the NICU. Continuing assessment with an online questionnaire may be useful to monitor changes over time in father's involvement in NICUs.

Neurodevelopmental, Mental Health, and Parenting Issues in Preterm Infants

The World Health Organization in its recommendations for the care of preterm infants has drawn attention to the need to address issues related to family involvement and support, including education, counseling, discharge preparation, and peer support. A failure to address these issues may translate into poor outcomes that extend across the lifespan. In this paper, we review the often far-reaching impact of preterm birth on the health and wellbeing of the parents and highlight the ways in which psychological stress may have a negative long-term impact on the parent-child interaction, attachment, and the styles of parenting. This paper addresses the following topics: (1) neurodevelopmental outcomes in preterm infants, including cognitive, sensory, and motor difficulties, (2) long-term mental health issues in premature infants that include elevated rates of anxiety and depressive disorders, autism, and somatization, which may affect social relationships and quality of life, (3) adverse mental health outcomes for parents that include elevated rates of depression, anxiety, and symptoms of post-traumatic stress, as well as increased rates of substance abuse, and relationship strain, (4) negative impacts on the parent-infant relationship, potentially mediated by maternal sensitivity, parent child-interactions, and attachment, and (5) impact on the parenting behaviors, including patterns of overprotective parenting, and development of Vulnerable Child Syndrome. Greater awareness of these issues has led to the development of programs in neonatal mental health and developmental care with some data suggesting benefits in terms of shorter lengths of stay and decreased health care costs.

Musical and vocal interventions to improve neurodevelopmental outcomes for preterm infants

BACKGROUND

Preterm birth interferes with brain maturation, and subsequent clinical events and interventions may have additional deleterious effects. Music as therapy is offered increasingly in neonatal intensive care units aiming to improve health outcomes and quality of life for both preterm infants and the well-being of their parents. Systematic reviews of mixed methodological quality have demonstrated ambiguous results for the efficacy of various types of auditory stimulation of preterm infants. A more comprehensive and rigorous systematic review is needed to address controversies arising from apparently conflicting studies and reviews.

OBJECTIVES

We assessed the overall efficacy of music and vocal interventions for physiological and neurodevelopmental outcomes in preterm infants (< 37 weeks' gestation) compared to standard care. In addition, we aimed to determine specific effects of various interventions for physiological, anthropometric, social-emotional, neurodevelopmental short- and long-term outcomes in the infants, parental well-being, and bonding.

SEARCH METHODS

We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, PsycINFO, Web of Science, RILM Abstracts, and ERIC in November 2021; and Proquest Dissertations in February 2019. We searched the reference lists of related systematic reviews, and of studies selected for inclusion and clinical trial registries.

SELECTION CRITERIA

We included parallel, and cluster-randomised controlled trials with preterm infants < 37 weeks` gestation during hospitalisation, and parents when they were involved in the intervention. Interventions were any music or vocal stimulation provided live or via a recording by a music therapist, a parent, or a healthcare professional compared to standard care. The intervention duration was greater than five minutes and needed to occur more than three times.

DATA COLLECTION AND ANALYSIS

Three review authors independently extracted data. We analysed the treatment effects of the individual trials using RevMan Web using a fixed-effects model to combine the data. Where possible, we presented results in meta-analyses using mean differences with 95% CI. We performed heterogeneity tests. When the I2 statistic was higher than 50%, we assessed the source of the heterogeneity by sensitivity and subgroup analyses. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included 25 trials recruiting 1532 infants and 691 parents (21 parallel-group RCTs, four cross-over RCTs). The infants gestational age at birth varied from 23 to 36 weeks, taking place in NICUs (level 1 to 3) around the world. Within the trials, the intervention varied widely in type, delivery, frequency, and duration. Music and voice were mainly characterised by calm, soft, musical parameters in lullaby style, often integrating the sung mother's voice live or recorded, defined as music therapy or music medicine. The general risk of bias in the included studies varied from low to high risk of bias. Music and vocal interventions compared to standard care Music/vocal interventions do not increase oxygen saturation in the infants during the intervention (mean difference (MD) 0.13, 95% CI -0.33 to 0.59; P = 0.59; 958 infants, 10 studies; high-certainty evidence). Music and voice probably do not increase oxygen saturation post-intervention either (MD 0.63, 95% CI -0.01 to 1.26; P = 0.05; 800 infants, 7 studies; moderate-certainty evidence). The intervention may not increase infant development (Bayley Scales of Infant and Toddler Development (BSID)) with the cognitive composition score (MD 0.35, 95% CI -4.85 to 5.55; P = 0.90; 69 infants, 2 studies; low-certainty evidence); the motor composition score (MD -0.17, 95% CI -5.45 to 5.11; P = 0.95; 69 infants, 2 studies; low-certainty evidence); and the language composition score (MD 0.38, 95% CI -5.45 to 6.21; P = 0.90; 69 infants, 2 studies; low-certainty evidence). Music therapy may not reduce parental state-trait anxiety (MD -1.12, 95% CI -3.20 to 0.96; P = 0.29; 97 parents, 4 studies; low-certainty evidence). The intervention probably does not reduce respiratory rate during the intervention (MD 0.42, 95% CI -1.05 to 1.90; P = 0.57; 750 infants; 7 studies; moderate-certainty evidence) and post-intervention (MD 0.51, 95% CI -1.57 to 2.58; P = 0.63; 636 infants, 5 studies; moderate-certainty evidence). However, music/vocal interventions probably reduce heart rates in preterm infants during the intervention (MD -1.38, 95% CI -2.63 to -0.12; P = 0.03; 1014 infants; 11 studies; moderate-certainty evidence). This beneficial effect was even stronger after the intervention. Music/vocal interventions reduce heart rate post-intervention (MD -3.80, 95% CI -5.05 to -2.55; P < 0.00001; 903 infants, 9 studies; high-certainty evidence) with wide CIs ranging from medium to large beneficial effects. Music therapy may not reduce postnatal depression (MD 0.50, 95% CI -1.80 to 2.81; P = 0.67; 67 participants; 2 studies; low-certainty evidence). The evidence is very uncertain about the effect of music therapy on parental state anxiety (MD -0.15, 95% CI -2.72 to 2.41; P = 0.91; 87 parents, 3 studies; very low-certainty evidence). We are uncertain about any further effects regarding all other secondary short- and long-term outcomes on the infants, parental well-being, and bonding/attachment. Two studies evaluated adverse effects as an explicit outcome of interest and reported no adverse effects from music and voice.

AUTHORS' CONCLUSIONS

Music/vocal interventions do not increase oxygen saturation during and probably not after the intervention compared to standard care. The evidence suggests that music and voice do not increase infant development (BSID) or reduce parental state-trait anxiety. The intervention probably does not reduce respiratory rate in preterm infants. However, music/vocal interventions probably reduce heart rates in preterm infants during the intervention, and this beneficial effect is even stronger after the intervention, demonstrating that music/vocal interventions reduce heart rates in preterm infants post-intervention. We found no reports of adverse effects from music and voice. Due to low-certainty evidence for all other outcomes, we could not draw any further conclusions regarding overall efficacy nor the possible impact of different intervention types, frequencies, or durations. Further research with more power, fewer risks of bias, and more sensitive and clinically relevant outcomes are needed.

Parental representations after preterm birth: a narrative review

Preterm birth accounts for nearly 15 million births annually worldwide and constitutes a considerable risk factor for atypical development. This birth context is a source of stress for the parents and often leads to an early separation between their child and them. Research on the influence of the birth status on the infant's attachment style has shown no systematic link between preterm birth and the development of insecure attachment in children born preterm. This has opened up research perspectives in understanding the role of environmental factors. A literature review was conducted to present an overview of the current findings on parental representations (PR), particularly maternal ones, and their role in the context of preterm birth. PR quality appears to be associated with specific dyadic interaction patterns, thus exposing vulnerability factors. Studies exploring PR have pointed out the importance of considering parental mental elaboration mechanisms and contextual moderators in supporting socio-emotional development among children born preterm. We discussed the challenges of investigating PR in the context of preterm birth for future studies and emphasized the need for research studies to be conducted according to a developmental and non-deterministic perspective. This narrative review also aimed to highlight the importance of family centered care interventions in the context of a public policy focused on the child's "First 1,000 days" of life.

Perceived stress of mothers and fathers on two NICUs before and during the SARS-CoV-2 pandemic

Parents of very low birth weight (VLBW) infants in a neonatal intensive care unit experienced additional stress during the SARS-CoV-2 pandemic due to the related restrictions in hospital visiting policies. Our study aimed to compare parents' burdens before and during the pandemic. This survey included 121 parents of 76 VLBW infants in two European Level IV perinatal centers before and during the pandemic. We performed standardized parent questionnaires with mothers and fathers separately to evaluate their emotional stress and well-being. The pandemic worsened the emotional well-being of parents of VLBW infants, particularly of mothers. During the pandemic, mothers reported significantly higher state anxiety levels (48.9 vs. 42.9, p = 0.026) and hampered bonding with the child (6.3 vs. 5.2, 0 = 0.003) than before. In addition, mothers felt more personally restricted than fathers (6.1 vs. 5.2, p = 0.003). Fathers experienced lower levels of stress than mothers; they were equally burdened before and during the pandemic. Restrictions in visiting policies for families of VLBW infants during the SARS-CoV-2 pandemic have a significant negative impact on parental stress and should therefore be applied cautiously.

The impact of pandemic restrictive visiting policies on infant wellbeing in a NICU

BACKGROUND

Given the countrywide lockdown in the first pandemic period and the respective Hospital restrictive policies, we aimed to investigate if the SARS-COV-2 pandemic was associated to a reduced parental presence in the NICU and in which form this had an impact on infant wellbeing.

METHODS

Retrospective cohort study about altered NICUs parental presence (measured by number of visits and kangaroo care time) due to pandemic restrictive policies and its impact on infant wellbeing (measured through The Neonatal Pain Agitation and Sedation scale and nurses' descriptive documentation).

RESULTS

Presence of both parents at the same time was significantly lower during pandemic. Contrary, maternal presence only and total kangaroo-care time were higher within the pandemic (163.36 ± 94.07 vs 122.71 ± 64.03; p = 0.000). Lower NPASS values were documented during the lookdown (1.28 ± 1.7 vs 1.78 ± 2.2; p = 0.000).

CONCLUSION

Data collected through the pandemic confirm the importance of parental presence for infants' wellbeing in a NICU setting.

IMPACT

Parental support is an extremely important aspect for infants hospitalized in an intensive care unit. Their presence was limited in many NICUs worldwide during the SARS-COV-2 pandemic. This study confirm the importance of parental presence for infants' wellbeing also in a pandemic situation. Our results support a family-centered newborn individualized developmental care approach in the NICU.

The neonatal perspective of paid family medical leave (PFML)

Paid family medical leave (PFML) offers infants, parents, and society at large numerous health and economic benefits. It has been shown to improve neonatal and maternal outcomes, breastfeeding rates, familial relationships, and decrease gender inequalities in the workplace. Though the economic feasibility of PFML has been well established in many countries, the USA lacks a cohesive and comprehensive federal PFML policy. Neonatal healthcare providers play a critical role in impacting neonatal health and should actively advocate for the development and promotion of a federal PFML policy, particularly one that is inclusive of both mothers and fathers and is at least 12 weeks in duration.

Relationship between health literacy and maternal bonding: A prospective cross-sectional study

Background

Maternal bonding has an effect on the baby throughout its life. The effective and complete occurrence of the mother-baby bond depends on many factors which can be individual or environmental. Health literacy plays an important role in the health behaviors of individuals, the prevention of diseases, and the improvement of health. Health literacy is a key determinant of medical-related issues.

Objectives

This study was conducted to examine the relationship between health literacy and mother-infant attachment in infancy. It was aimed to predict the biopsychosocial impact of the mother's health literacy level on the baby's life indirectly.

Materials and Methods

The sample of this descriptive and cross-sectional study included 202 mothers. Data were collected using the Personal Information Form, Health Literacy Scale-Short Form (HLS-SF), and Maternal Attachment Inventory (MAI).

Results

There were no statistical correlations between HLS-SF scores and MAI scores. In addition, the mothers with a statistically significant higher MAI score were those whose partners had a higher education level, had a planned pregnancy, worked in the prenatal period, never breastfed, and had earlier skin-to-skin contact with their baby. (P < 0.05).

Conclusion

Factors that may affect maternal bonding, which affects a baby's entire life, should be addressed by the authorities and necessary improvements would be useful. We believe that this previously unexplored study will pave the way for multicenter similar studies.

Developmental Cascades Link Maternal-Newborn Skin-to-Skin Contact with Young Adults' Psychological Symptoms, Oxytocin, and Immunity; Charting Mechanisms of Developmental Continuity from Birth to Adulthood

Premature birth disrupts the continuity of maternal-newborn bodily contact, which underpins the development of physiological and behavioral support systems. Utilizing a unique cohort of mother-preterm dyads who received skin-to-skin contact (Kangaroo Care, KC) versus controls, and following them to adulthood, we examined how a touch-based neonatal intervention impacts three adult outcomes; anxiety/depressive symptoms, oxytocin, and secretory immunoglobulin A (s-IgA), a biomarker of the immune system. Consistent with dynamic systems' theory, we found that links from KC to adult outcomes were indirect, mediated by its effects on maternal mood, child attention and executive functions, and mother-child synchrony across development. These improvements shaped adult outcomes via three mechanisms; (a) "sensitive periods", where the infancy improvement directly links with an outcome, for instance, infant attention linked with higher oxytocin and lower s-IgA; (b) "step-by-step continuity", where the infancy improvement triggers iterative changes across development, gradually shaping an outcome; for instance, mother-infant synchrony was stable across development and predicted lower anxiety/depressive symptoms; and (c) "inclusive mutual-influences", describing cross-time associations between maternal, child, and dyadic factors; for instance, from maternal mood to child executive functions and back. Findings highlight the long-term impact of a birth intervention across development and provide valuable insights on the mechanisms of "developmental continuity", among the key topics in developmental research.

Prevalence of postpartum post-traumatic stress disorder and its determinants in Mainland China: A systematic review and meta-analysis

BACKGROUND

The prevalence and risk factors of postpartum posttraumatic stress disorder reported by population-based studies have significantly varied and the data are all collected from regional populations in Mainland China.

AIMS

To utilize published data to estimate the overall prevalence of postpartum posttraumatic stress disorder and its determinants in Mainland China.

METHODS

Comprehensively electronic searches were performed across six English databases and three Chinese databases. Random effects of the meta-analysis were performed to evaluate the pooled prevalence of postpartum posttraumatic stress disorder. Meta-regression was performed with the variable of study design, sample size, setting, measures, region, time points, and publication year.

RESULTS

Totaling of nineteen studies was included, with a sample size of 13,231 postpartum women. The pooled prevalence of postpartum posttraumatic stress disorder was 11.2 % in Mainland China, with a higher prevalence at the timepoint within 1 month postpartum (18.1 %). Significant publication bias and heterogeneity were found (I² = 97.1 %). Sample size and measurements were conditional on the prevalence of postpartum posttraumatic stress disorder. Postpartum depressive symptoms, sleep problems, cesarean section, and low levels of social support were the major risk factors for postpartum posttraumatic stress disorder. While being the one child in the family was the protective factor.

CONCLUSION

An increasing prevalence of posttraumatic stress disorder within one month postpartum significantly arises awareness to provide screening and more mental health services during this period. Screening programs for postpartum posttraumatic stress disorder are still needed in Mainland China.

Cross-modal coherence and incoherence of early infant interactive behavior: links to attachment in infants born very preterm or full-term

Infants exhibit flexibly organized configurations of facial, vocal, affective, and motor behavior during caregiver-infant interactions that convey convergent messages about their internal states and desires. Prior work documents that greater cross-modal discrepancy at 4 months predicts disorganized attachment. Here, we evaluated whether: very preterm (VPT) or full-term (FT) status predicts cross-modal coherence or incoherence in infants' behavior with the caregiver at 3 months; and, regardless of prematurity, whether cross-modal interactive coherence or incoherence predicts 12-month attachment. Participants included 155 infants (85 FT; 70 VPT), and their mothers followed from birth to 12 months (corrected age). Infants' cross-modal coherent and incoherent responses were scored microanalytically from videotaped en-face interactions. Infants' attachment security was evaluated during Ainsworth's Strange Situation. Infants born VPT exhibited more incoherent cross-modal responses and insecure attachment than infants born FT. Regardless of prematurity, infants' coherent and incoherent cross-modal interactive behaviors at 3 months predicted different attachment patterns at 12 months.

High rate of insecure attachment patterns in preterm infants at early school age

AIM

In preterm infants, insecure attachment is associated with behavioural and emotional problems but data on attachment beyond toddler age are scarce. This study assessed attachment security at 6-8 years in very and moderate or late preterm infants. The results were compared to a non-clinical full-term sample.

METHODS

Attachment security of 38 very and 20 moderate or late preterm infants was assessed during a home visit with the German version of the Attachment Story Completion Task. Attachment patterns of 28 full-term controls were taken from a previous study. Primary outcomes were attachment security and attachment security score. Secondary outcomes for the preterm groups were infant behavioural problems, parental stress, perceived social support, maternal depressive symptoms, and infant development.

RESULTS

Very preterm infants had the highest rate of insecure attachment (81%) compared to moderate or late preterm infants (60%) and full-term infants (47%); (p = 0.013). Attachment security scores differed significantly between very preterm and full-term infants (p = 0.001). Secondary outcomes were similar in very and moderate or late preterm cohorts.

CONCLUSION

Prematurity was associated with an increased risk of insecure attachment at early school age. Interventions targeting attachment security are reasonable considering the high rate of behavioural problems following premature birth.

The Association between Prematurity, Antibiotic Consumption, and Mother-Infant Attachment in the First Year of Life

Antibiotics have individual and public-health drawbacks. Nevertheless, mother-infant attachment quality and maternal sensitivity are associated with antibiotic use. Ambivalent-attached infants are more likely to consume antibiotics than other infants. Conceivably, the emotional over-externalization of ambivalent-attached infants and maternal anxiety when infants are ill raise concerns in healthcare professionals, leading to antibiotic over-prescriptions. However, because infants prematurely born, particularly those with less than 32 weeks of gestation, are under more accurate health vigilance, the impact of infant and maternal behavior on antibiotic prescription may vanish in this sample. To test this hypothesis, we performed a longitudinal study to compare antibiotic use and the quality of mother-infant attachment in three groups: 86 infants born at full-term, 44 moderate-to-late preterm infants (32-36 gestation weeks), and 58 very-to-extreme preterm infants (<32 gestation weeks). Infants' attachment was observed with the Ainsworth Strange Situation's experimental paradigm at 12 months of corrected age. Findings indicate that infant attachment strategy is associated with antibiotics uptake, but results vary across samples. The proportion of infants that used antibiotics is highest among ambivalent-attached infants in the full-term sample but highest among avoidant-attached infants in the very-to-extreme premature sample. Moreover, higher infant gestational age and lower maternal sensitivity determine higher antibiotic use.

Biomedical and Psychosocial Determinants of Early Neurodevelopment After Preterm Birth

Prematurity and them related conditions are subject of scientific discussion. From the point of view optimization of postpartum processes, timely assessment of individual biomedical and psychosocial conditions and management of preventive intervention is very important, because of its linkage to issues of preterm infants and their families in long-term perspectives. The goal of the literature review is to bring together existing body of knowledge on biomedical, psychological, and social issues of premature infants related to early neurodevelopment in order to achieve better systemic vision. For this goal scientific articles related to neurological development delay of premature children and the possibilities of their timely identification were processed using electronic scientific search systems. Diagnostic tools to identify at-risk children and early intervention programs discussed in the article, significantly improve the chances of premature child development. In the article Introduced materials are to support: Clinicians to make correct decisions regarding important components of premature infants; Healthcare policy makers to plan targeted programs and activities; Public to better understand prematurity issues, especially in case of prematurely-born family members.

Music Therapy in Preterm Infants Reduces Maternal Distress

Preterm delivery is a stressful event for mothers, posing them at risk for post-traumatic stress reactions. This study examined the degree of depressive symptoms and post-traumatic stress in mothers of preterm infants born before 32 gestational weeks depending on whether the infant received music therapy in the neonatal intensive care unit (NICU) or not. We included 33 mothers of preterm infants enrolled in a previously described prospective randomized controlled trial, of whom 18 received music therapy (mean mothers' age 34.1 ± 4.6 years) and 15 did not (mean mothers' age 29.6 ± 4.2). The degree of depressive symptoms, anxiety and acute stress reactions of these mothers were measured by using the German version of the Center for Epidemiologic Studies Depression Scale (CES-D) and Impact of Events Scale-Revised (IES-R) one week after birth (T1) and at infants' hospital discharge (T2). 605 music therapy sessions with a mean duration of 24.2 ± 8.6 min (range 10 to 50 min) were conducted two times a week from the second week of life (T1) until discharge (T2) to the infants from the intervention group. The infants from the control group received standard medical care without music therapy. The mean total CES-D score decreased from T1 (mean 34.7, 95% Confidence Interval (CI) 31.1-38.1) until T2 in all mothers (mean 16.3, 95% CI 12.6-20.1). Mothers whose infants received music therapy showed stronger declines of depressive and stress symptoms (with music therapy: CES-D mean difference of total score 25.7, 95% CI 20.0-31.3, IES-R mean difference of total score 1.7, 95% CI 0.9-2.5, IES-R mean difference of subcategory hyperarousal 10.2, 95% CI 6.2-14.3; without music therapy: CES-D mean difference of total score 9.5, 95% CI 3.8-15.3, IES-R mean difference of total score 0.1, 95% CI -1.0-1.2, IES-R mean difference of subcategory hyperarousal 1.6, 95% CI -4.7-7.9). Effect sizes were strong for CES-D, IES-R, and the hyperarousal subcategory, moderate for intrusion, and low for avoidance. These findings show that mothers of preterm infants are highly susceptible to supportive non-medical interventions such as music therapy to reduce psychological symptoms and distress during their infants' NICU stay.

The Role of Family Function and Triadic Interaction on Preterm Child Development-A Systematic Review

Preterm infants are at high risk of developmental disability/delay and are more dependent on their caregiving environment for regulation due to their neurological immaturity. A premature birth is also a major stressor to the family system that constitutes the infant's caregiving environment. The following systematic review investigates whether families with preterm children differ from families with full-term children in their interactions, and what impact the quality of family interaction has on child development. Using the Cochrane model, we conducted a systematic review of quantitative studies published in psycINFO, socINDEX, and PubMed, concerning family quality in triadic interactions in families with premature infants and children, and at least one child development outcome variable. The quality of these studies was assessed using the Newcastle-Ottawa scale assessment form for cohort studies (NOS). Eleven studies were included in the review. Quality of family interactions is either equal to or poorer in families with preterm children, compared with families with full-term children. Importantly, the link between quality of family interactions and child development outcome is stronger in preterm children compared with full-term children, regarding both positive and negative influence. Our results highlight the importance of strengthening family interactions in order to promote development in preterm children. Notably, this review provides the first systematic overview of family function and the quality of triadic interactions in preterm families. The limited number of studies with a family-system focus makes it difficult for us to draw any definitive conclusions, while underscoring the need for more observational studies, particularly post-infancy, to be able to identify specific aspects of family interactions that may be critical for preterm child development.

Parent-infant interaction quality is related to preterm status and sensory processing

BACKGROUND

Parent-infant interactions provide the foundation for the development of infant socioemotional wellbeing. Preterm birth can have a substantial, and often detrimental, impact on the quality of early parent-infant interactions. Sensory processing difficulties, common in preterm infants, are further associated with poorer interaction quality. There is a paucity of research, however, examining the links between the quality of parent-infant interaction, preterm birth, and sensory processing difficulties. This study aimed to characterise the quality of interactions of parent-infant dyads involving preterm infants who may display sensory processing differences and examine the associations between parent-infant interaction quality, preterm status and infant sensory processing.

METHOD

67 parent-infant dyads (12-months infant age, 22 preterm, 45 full-term) participated in a recorded, semi-structured 15-minute play interaction. Parents also filled out questionnaires on demographics, and infant sensory processing (Infant and Toddler Sensory Profile-2; ITSP-2). Interaction quality was rated using the Parenting Interactions with Children: Checklist of Observations Linked to Outcomes (PICCOLO).

RESULTS

Preterm and full-term infants differed in sensory processing and parent-infant interaction. Infant prematurity was associated with the sensory domains of; visual (r = - 0.37, p = .005), touch (r = - 0.39, p = .002), and movement (r_s = - .32, p = .01), as well as the interaction domains of; responsivity (r_s;= - .43, p = .001), teaching (r_s = - .31, p = .02), and interaction total score (r = - 0.34, p = .01). Interaction quality was related to sensory registration (r_s = - .38, p = .008), auditory (r_s = - .34, p = .02), seeking (r_s = .29, p = .05) and sensory behavioural scores (r_s = - .52, p < .001). Overall, interaction quality was best predicted by infant prematurity and auditory scores, R² = .15, F(1, 47) = 4.01, p = .02.

DISCUSSION

Preterm infants differed from their full-term peers in both their sensory processing and in their dyadic interactions with parents. Preterm status was associated with less responsivity and teaching and was found to predict overall interaction quality. Poorer infant sensory processing was associated with less parental teaching, affection and responsivity during interactions. Our results suggest that preterm birth is related to sensory processing difficulties, and that prematurity and sensory processing are differentially associated with aspects of interaction quality. These findings support the further examination of the interplay between preterm birth, sensory processing, and parent-infant interaction quality.

Effect of Prematurity and Temperament on the Mother-Infant Interaction

Abstract We evaluated the effect of prematurity and the infant’s temperament on the mother-infant behaviors in the Face-to-Face Still-Face Paradigm (FFSF). The study included 75 mothers and their infants (37 preterm and 38 term) between three and four months of age (corrected age for preterm infants). The mothers responded to a perception scale of the infants’ temperament and the dyads were observed in a structured condition (FFSF). The FFSF Paradigm, divided into three episodes, made it possible to analyze the behaviors of: Positive Social Orientation, Negative Social Orientation and Self-comfort. The averages recorded for these categories were analyzed in a Multivariate ANOVA (factors: prematurity and temperament). Temperament had more effect on maternal and infant behaviors, suggesting that this factor may influence mother-infant interaction. The results can guide possible interventions with families.

Maternal Confidence and Parenting Stress of First-Time Mothers in Taiwan: The Impact of Sources and Types of Social Support

The adjustment process to becoming a mother is affected by culture. However, earlier studies have not clarified the relationship between parenting stress, social support, and maternal confidence in non-Western women. This study examined the associations between different types and sources of social support, maternal confidence, and parenting stress experienced by first-time mothers. The sample consisted of first-time mothers with a child under one year of age in northern Taiwan, and a total of 205 valid questionnaires were collected. The results supported the stress-buffering hypothesis, which suggests that social support reduces the adverse effect of stress on maternal confidence. Although previous studies have suggested that spouses and maternal relatives are critical in supporting first-time mothers’ transition into their new roles, each source did not show a mediator effect in our study. The beneficial effect of social support was found only when all social network members collectively participated. Regarding the types of social support, only appraisal support had a significant mediator effect; no effect was found for emotional, instrumental, or informational support. These findings add to our understanding of how different types and sources of social support play a role in helping first-time mothers adapt.

Silence matters: The role of pauses during dyadic maternal and paternal vocal interactions with preterm and full-term infants

This study examined the characteristics of the vocal behaviors of parents and preterm infants, as compared to their term-born peers, at three months of age. Potential links between specific features of parental IDS and infants' vocal activity were also sought. We analyzed the frequencies and durations of vocalizations and pauses during the dyadic interactions of 19 preterm and 19 full-term infants with their mothers and fathers. The results showed that the duration of the vocalizations was shorter for the preterm than for the full-term infants, regardless of the interactive partner. Mothers vocalized more frequently and for a longer time than fathers, regardless of the group, but only the frequency of paternal utterances was significantly and positively correlated with the frequency and duration of infant vocalizations. Frequent conversational pauses of a relatively short total duration seemed to be related to more active infants' vocal participation, regardless of prematurity and parent gender.

Cuddling very and extremely preterm babies in the delivery room is a positive and normal experience for mothers after the birth

AIM

Extremely preterm infants are separated from their mothers immediately after birth and not placed skin-to-skin in routine neonatal intensive care unit settings. Visual and physical contact in the delivery room as a first cuddle potentially can facilitate early parent-infant interaction and reduce the trauma of separation. Our aim in this study was to explore mothers' experience of delivery room cuddle by collecting qualitative feedback via emotional mapping.

METHODS

Six mothers experiencing delivery room cuddle had been recruited (GA of their babies 24 + 5-29 + 0 weeks, birth weight 540-1019 g). Using a descriptive qualitative approach, semi-structured interviews were performed with six mothers following consent via Zoom or phone between September 2020 and March 2021. Interviews were transcribed using AI Otter and then analysed using thematic analysis.

RESULTS

Analysis of the participants' experiences revealed five themes: fears and hopes around delivery; the moment of delivery-recognising uncertainty; reclaiming normalcy; forming connections; and the journey ahead as an empowered parent.

CONCLUSION

All mothers reported positive emotions about the cuddle with their baby. They highlighted that this physical contact was often the only positive and 'normal' birth experience they had from the time of delivery.

The Effect of Mindfulness-Based Stress Reduction on Posttraumatic Stress of Mothers With Premature Neonates Admitted to a Neonatal Intensive Care Unit

Mothers experience posttraumatic stress disorder with the birth of a premature neonate. The purpose of this study was to determine the effect of mindfulness-based stress reduction on posttraumatic stress of mothers with premature neonates in Iran. Sixty mothers with premature neonates were selected by using convenience sampling and stratified random allocation. Mindfulness-based stress reduction was trained and mean posttraumatic stress disorder was measured. Mean posttraumatic stress scores of the 2 groups were statistically significant immediately and 1 month after the intervention (independent t test, P < .05). Posttraumatic stress of both groups reduced over time, but this reduction was more significant in the intervention group (repeated-measures analysis of variance, P < .05). Concerning the positive role of mindfulness-based stress reduction in posttraumatic stress disorder of mothers, it is recommended to use this approach in care programs of mothers with premature neonates.

Preterm birth, poor foetal growth and anxiety disorders in a Finnish nationwide register sample

Aim

We examined the associations between preterm birth, poor foetal growth and anxiety disorders among children and adolescents. Additionally, we examined the impact of common comorbidities and specific anxiety disorders separately.

Methods

Three Finnish registers provided data on a nationwide birth cohort of 22,181 cases with anxiety disorders and 74,726 controls. Conditional logistic regression was used to examine the associations.

Results

Extremely very preterm birth and moderate‐late preterm birth were associated with increased adjusted odds ratios (aOR) for anxiety disorders (aOR 1.39, 95% CI 1.11–1.75 and aOR 1.13, 95% CI 1.03–1.23, respectively). Weight for gestational age of less than −2SD (aOR 1.29, 95% CI 1.17–1.42) and −2SD to −1SD (aOR 1.08, 95% CI 1.03–1.14) were associated with increased odds ratios for anxiety disorders. When comorbidities were considered, the associations became statistically insignificant for pure anxiety disorders, but remained significant in the groups with comorbid depressive or neurodevelopmental disorders.

Conclusion

Preterm birth and poor foetal growth increased the odds for anxiety disorders. However, the associations seem to be explained by the conditions of comorbid depressive and neurodevelopmental disorders. Comorbidities should be considered when examining and treating child and adolescent anxiety disorders.

Effects of maternal sound stimulation on preterm infants: A systematic review and meta‐analysis

AIMS

To evaluate the effects of maternal sound stimulation on preterm infants.

BACKGROUND

With an increased focus of studies on maternal sound stimulation for preterm infants, there is a need for an up-to-date systematic review and meta-analysis of randomized controlled trials to measure the effects of maternal sound stimulation on preterm infants.

DESIGN

A systematic review and meta-analysis.

DATA SOURCES

We searched PubMed, EMBASE, the Cochrane Library, CINAHL Complete, VIP Journal Integration Platform, China National Knowledge Infrastructure, Wanfang Data and China Biology Medicine disc from database establishment to 28 April 2021.

REVIEW METHODS

We conducted the meta-analysis using Review Manager 5.3. Integrative description was used for data that were not suitable for meta-analysis.

RESULTS

A total of 380 studies between 1979 and 2021 were retrieved and 26 were included in this systematic review. Maternal sound stimulation could significantly reduce the pain level and increase the comfort level of preterm infants during a painful procedure. Compared with routine care, maternal sound stimulation could help preterm infants achieve better physiological stability by reducing their heart rate and increasing their oxygen saturation.

CONCLUSION

Maternal sound stimulation is a feasible and effective intervention for preterm infants, which is highly recommended in the clinical setting.

Maternal Milk Provision in the Neonatal Intensive Care Unit and Mother–Infant Emotional Connection for Preterm Infants

Maternal milk (MM) intake during neonatal intensive care unit (NICU) hospitalization is associated with improved neurodevelopment in preterm infants. Underlying mechanisms may include stronger mother–infant emotional connection. This paper examines associations between MM provision in the NICU with maternal connection to her infant using three factors validated in our sample: maternal sensitivity, emotional concern, and positive interaction/engagement. We studied 70 mothers of infants born <1500 g and/or <32 weeks’ gestation. Associations between MM provision and mother–infant connection were modeled using median regression adjusted for clustering. Mothers who provided exclusive MM (i.e., 100% MM, no other milk) reported higher levels of maternal sensitivity by a median score of 2 units (β = 2.00, 95% CI: 0.76, 3.24, p = 0.002) than the mixed group (i.e., MM < 100% days, other milk ≥1 days), as well as greater emotional concern (β = 3.00, 95% CI: −0.002, 6.00, p = 0.05). Among mothers of very preterm infants, greater milk provision was associated with greater maternal sensitivity, but also with greater emotional concern about meeting the infant’s needs. These findings highlight the importance of supporting MM provision and early infant care as an integrated part of lactation support. The findings may also provide insight into links between MM provision in the NICU and infant neurodevelopment.

Parenting and Neurobehavioral Outcomes in Children Born Moderate-to-Late Preterm and at Term

OBJECTIVES

To compare the parenting environment and the relationships between parenting behaviors and concurrent child neurobehavioral outcomes at 2 years of corrected age between children born moderate-to-late preterm (MLP; 32-36 weeks of gestation) and at term (≥37 weeks of gestation).

STUDY DESIGN

Participants were 129 children born MLP and 110 children born at term and their mothers. Mothers' parenting behaviors (sensitivity, structuring, nonintrusiveness, nonhostility) were assessed at 2 years of corrected age using the Emotional Availability Scales. Child cognitive and language development were assessed using the Bayley Scales of Infant and Toddler Development, and social-emotional competence using the Infant Toddler Social and Emotional Assessment.

RESULTS

Mothers of children born MLP and at term displayed similar parenting behaviors overall, with slightly lower nonintrusiveness in mothers of children born MLP (adjusted mean difference -0.32 [-0.60, -0.04]; P = .03). In both groups of children, greater maternal sensitivity was associated with better cognitive development (P < .001 MLP; P = .02 term), increased maternal structuring was associated with better social-emotional competence (P = .02 MLP; P = .03 term), and higher maternal nonintrusiveness was associated with better cognitive, language, and social-emotional outcomes (all P < .04). Greater maternal sensitivity and structuring were associated with better language development in children born MLP but not in children born at term.

CONCLUSIONS

Parenting behaviors are important for neurobehavioral outcomes in children born MLP and at term. Language development may be more strongly influenced by select parenting behaviors in children born MLP compared with children born at term.

Short-term Music Therapy for Families With Preterm Infants: A Randomized Trial

OBJECTIVES

To evaluate short-term effects of music therapy (MT) for premature infants and their caregivers on mother-infant bonding, parental anxiety, and maternal depression.

METHODS

Parallel, pragmatic, randomized controlled-trial conducted in 7 level III NICUs and 1 level IV NICU in 5 countries enrolling premature infants (<35 weeks gestational age at birth) and their parents. MT included 3 sessions per week with parent-led, infant-directed singing supported by a music therapist. Primary outcome was mother-infant bonding as measured by the Postpartum Bonding Questionnaire (PBQ) at discharge from NICU. Secondary outcomes were parents' symptoms of anxiety measured by General Anxiety Disorder-7 (GAD-7) and maternal depression measured by Edinburgh Postpartum Depression Scale (EPDS). Group differences at the assessment timepoint of discharge from hospital were tested by linear mixed effect models (ANCOVA).

RESULTS

From August 2018 to April 2020, 213 families were enrolled in the study, of whom 108 were randomly assigned to standard care and 105 to MT. Of the participants, 208 of 213 (98%) completed treatment and assessments. Participants in the MT group received a mean (SD) of 10 sessions (5.95), and 87 of 105 participants (83%) received the minimum of 6 sessions. The estimated group effect (95% confidence interval) for PBQ was -0.61 (-1.82 to 0.59). No significant differences between groups were found (P = .32). No significant effects for secondary outcomes or subgroups were found.

CONCLUSIONS

Parent-led, infant-directed singing supported by a music therapist resulted in no significant differences between groups in mother-infant bonding, parental anxiety, or maternal depression at discharge.

Neonates in the Intensive Care Unit: Maternal Health-Related Quality of Life and Depression After Term and Preterm Births

Background/Objective: To examine maternal physical and mental health-related quality of life (HRQoL) and depression after early and late preterm and term births in the early postpartum period. Method: In a prospective pilot study, three groups of women whose newborns had to be treated in the neonatal ward during the immediate postpartum period were established and compared with each other: 20 women with extremely to very preterm birth, 20 with moderate to late preterm birth and 20 women with term birth. All participants completed the Short Form-12 Health Survey (SF-12) to measure HRQoL, and the Edinburgh Postnatal Depression Scale (EPDS) to detect depressive symptoms combined with independently developed questions to evaluate anxiety and psychological distress. Results: Maternal psychological HRQoL was significantly worse in the very preterm birth group compared to moderate to late preterm birth (p < 0.001) and full-term birth groups (p = 0.004). There were no differences between the birth groups in depressive symptoms (p = 0.083), anxiety (p = 0.238), perceived stress (p = 0.340) and the general psychological distress values (p = 0.755). In the EPDS, the depression screening instrument 30 to 65% were beyond the cut-off-value to detect major depression. Conclusions: During the early postpartum period, an extensive medical care focussing on acute stress, HRQoL parameters and depression may be a good step to improving maternal well-being.

Spontaneous movements, motor milestones, and temperament of preterm-born infants: Associations with mother-infant attunement

Preterm-born infants and their mothers are at higher risk of showing less attuned interactions. We sought to identify characteristics of preterm-born infants associated with the attunement of mother-infant interactions at the corrected ages of 3-4 months, looking specifically at motor behaviors. We focused on infants' spontaneous movements, achievement of motor milestones, and temperament, which at this young age is often manifested via movement. Sixty preterm-born infants (Mdn_{gestation age in weeks}  = 33, 57.38% male, corrected age Mdn = 14 weeks, interquartile range = 13-16) and their mothers participated. Independent observers rated mother-infant attunement, infants' spontaneous movements, and infants' achievement of motor milestones. Mothers reported infant temperament. We found infants' smooth and fluent movement character and continual fidgety movements were associated with better attunement in terms of higher maternal sensitivity and non-intrusiveness and higher infant responsiveness and involvement. Unexpectedly, infants' achievement of motor milestones was not significantly associated with mother-infant attunement, and maternal reports of infants' higher soothability were associated with lower maternal sensitivity. The study illustrates the value of including the assessment of infants' spontaneous movements, designed for early detection of neurological deficiencies, in research and in clinical practice with parents and preterm-born infants.

Early spectral EEG in preterm infants correlates with neurocognitive outcomes in late childhood

BACKGROUND

Evidence regarding the predictive value of early amplitude-integrated electroencephalography (aEEG)/EEG on neurodevelopmental outcomes at school age and beyond is lacking. We  aimed to investigate whether there is an association between early postnatal EEG and neurocognitive outcomes in late childhood.

METHODS

This study is an observational prospective cohort study of premature infants with a gestational age <28 weeks. The total absolute band powers (tABP) of the delta, theta, alpha, and beta bands were analyzed from EEG recordings during the first three days of life. At 10-12 years of age, neurocognitive outcomes were assessed using the Wechsler Intelligence Scale for Children 4th edition (WISC-IV), Vineland adaptive behavior scales 2nd edition, and Behavior Rating Inventory of Executive Function (BRIEF). The mean differences in tABP were assessed for individuals with normal versus unfavorable neurocognitive scores.

RESULTS

Twenty-two infants were included. tABP values in all four frequency bands were significantly lower in infants with unfavorable results in the main composite scores (full intelligence quotient, adaptive behavior composite score, and global executive composite score) on all three tests (p < 0.05).

CONCLUSIONS

Early postnatal EEG has the potential to assist in predicting cognitive outcomes at 10-12 years of age in extremely premature infants <28 weeks' gestation.

IMPACT

Evidence regarding the value of early postnatal EEG in long-term prognostication in preterm infants is limited. Our study suggests that early EEG spectral analysis correlates with neurocognitive outcomes in late childhood in extremely preterm infants. Early identification of infants at-risk of later impairment is important to initiate early and targeted follow-up and intervention.

Mother-Infant Bonding and Its Associated Factors Among Mothers in the Postpartum Period, Northwest Ethiopia, 2021

BACKGROUND

The emotional bond that a mother senses to her infant is essential to their social, emotional, and cognitive development. Understanding the level of mother-infant bonding plays an imperative role in the excellence of care. However, in Ethiopia, there is a paucity of information about mother-infant bonding in the postpartum period.

OBJECTIVE

This study aimed to assess the level of mother-infant bonding and its associated factors among mothers in the postpartum period, Debre Tabor Town Northwest Ethiopia, 2021.

METHODS

A community-based cross-sectional study was conducted with 422 postpartum mothers. The postpartum Bonding Questionnaire was used to assess mother-infant bonding. The Edinburgh Postnatal Depression Scale was used to assess postnatal depression. The level of marital satisfaction was assessed by using Kansas marital satisfaction scale. Social support was assessed by Oslo social support scale. A simple random sampling technique was applied to select study participants. Simple and multiple linear regression were used to identify potential factors associated with the mother-infant bonding scale. A P-value of <0.05 was considered to declare statistical significance.

RESULTS

In this study, out of 420 postpartum mothers,53 (12.6%) had a risk for the quality of mother-infant bond difficulties between mother and an infant; 8.1% of mothers had a risk for rejection and pathological anger; 3.6% of mothers had a risk for infant-focused anxiety and 1.9% of mothers had risk for incipient abuse of an infant. Maternal depression status [adjusted β coefficient (β) = 2.31, 95% CI: (1.98, 2.64)], non-union marital status [β = 15.58, 95% CI: (9.88, 21.27)], being government employee [β = -5.68, 95% CI: (-9.71, -1.64)], having current pregnancy complication [β = -7.28, 95% CI: (-12.27, -2.29)], being non-breastfeeding mother [β = 7.66, 95% CI: (2.94, 12.38)], substance use history [β = -6.55, 95% CI: (-12.80, -0.30)], and social support [β = -2, 95% CI: (-2.49, -1.50)] were statistically significant factors for mother-infant bonding.

CONCLUSION

Generally, a significant number of mothers had mother-infant bonding difficulties in the postpartum period. Preventing strategies for bonding difficulties focus on social support during pregnancy, screening postpartum mothers for postpartum depression, and special attention to substance users, non-union maternal status, and non-breastfeeding mothers.

Fathers' experiences of supporting their partners during their preterm infant's stay in the neonatal intensive care unit: a multi-method study

OBJECTIVE

To explore how the fathers experience their role as a support for their partner and the relationship with them during their preterm infant's stay in the NICU.

STUDY DESIGN

Multi-method longitudinal study involving ethnographic observation, semi-structured interviews, self-report questionnaires, and clinical information. Twenty fathers of preterm infants hospitalized in a level-III-NICU were included. Data were analyzed using thematic continent analysis.

RESULTS

Three main themes were identified: support for mother (subthemes: putting mother's and infant's needs first; hiding worries and negative emotions; counteracting the sense of guilt; fear that the mother would reject the child), mother's care for the infant (subthemes: observing mother engaged in caregiving; mother has "something extra"), and couple relationship (subthemes: collaboration; bond).

CONCLUSION

Fathers supporting their partners during the stay in the NICU experience emotional distress and the need for being supported that often are hidden. This demands a great deal of emotional and physical energy.

Effect of Infant Care Training on Maternal Bonding, Motherhood Self-Efficacy, and Self-Confidence in Mothers of Preterm Newborns

AIM

This study aims to evaluate the effect of infant care training on maternal bonding, motherhood self-efficacy, and self-confidence in mothers of preterm newborns and examine the relationship between them.

METHOD

The study was conducted experimentally with pre-test and post-test control groups in the Maternity Hospital. The population of the study consisted of late preterm newborns and their mothers (N = 81) who met the inclusion criteria of the study. Data was collected with an information form, a maternal bonding scale (MBS), a perceived maternal parenting self-efficacy scale (PMP-SE), and a Pharis self-confidence scale (PSCS). Mothers of the infants in the experimental group were given preterm infant care training as a nursing initiative.

RESULTS

In the study, the post-test MBS scores significantly increased in the experimental group, with a significant difference between all the sub-dimensions and the total scores of the PMP-SE post-test of mothers in both groups (p < 0.001). The post-test PSCS scores were significantly higher in the experimental group (p < 0.01). The correlation between MBS and PMP-SE (p < 0.05) mean scores of the mothers was positive, a correlation between PMP-SE and PSCS (p < 0.001) mean scores was positive and a correlation between PSCS and MBS (p < 0.05) mean scores was positive.

CONCLUSIONS

The existence of a directly proportional relationship between the variables of maternal bonding, motherhood self-efficacy, and self-confidence may mean that motherhood self-efficacy can be increased and motherhood self-confidence can be enhanced by supporting maternal bonding. Further studies starting from the prenatal period are recommended.

[Preterm birth: a risk for mental health?]

One in 12 children is born before 37 completed weeks of gestation and during the last decades survival rates and developmental outcomes of even very premature children have significantly improved. As a result, mental health sequelae of preterm birth are more frequently addressed. The manifestation of a distinct psychopathological profile with co-occurrence of symptoms associated with attention deficit/hyperactivity, autism spectrum and anxiety disorders has been recognized and discussed as "preterm behavioral phenotype", mainly affecting high-risk children with very low birth weights. Current research findings on parental psychological distress and early childhood developmental conditions after preterm birth indicate contextual factors that are of relevance, also for clinicians in psychotherapeutic practice.

The Impact of Formal School Entry on Children's Social Relationships with Parents, Siblings, and Friends

The normative transition to formal schooling confronts children with social challenges but also opportunities. Longitudinal research on how school entry impacts children's family and friend-ship relationships is scarce. This study investigated social relationship qualities with parents, siblings, and friends among 1110 children (49.9% female) from the prospective, population-based Bavarian Longitudinal Study at 6 years (before school entry) and 8 years using a forced-choice card-sorting task. Multivariate analyses of variance revealed significant effects of age (i.e., school entry) on social relationship qualities with mothers (Pillai's Trace (PT) = 0.28, F(9, 1101) = 47.73, p < 0.001), fathers (PT = 0.14, F(9, 1101) = 19.47, p < 0.001), siblings (PT = 0.27, F(9, 1101) = 46.14, p < 0.001), and friends (PT = 0.21, F(9, 1101) = 32.57, p < 0.001). On average, children reported higher levels of parental comfort after school entry. Companionable qualities increased in relationships with friends, whereas sibling relationships became more conflictual from preschool to early school age. Findings provide unique insights into how social relationships develop from preschool to early school age, supporting evidence of the growing importance of friends. Conflict was predominant and increasing in sibling relationships and should be considered more in future research.

Maternal Stress, Depression, and Attachment in the Neonatal Intensive Care Unit Before and During the COVID Pandemic: An Exploratory Study

The main aim of the present study was to investigate the effects of the COVID-19 pandemic on the mothers' postnatal depression, stress, and attachment during their stay in the Neonatal Intensive Care Unit (NICU). Twenty mothers of very premature infants born before 32weeks of gestational age were recruited at the Geneva University Hospital between January 2018 and February 2020 before the COVID-19 pandemic started. Mothers were screened for postnatal depression after their preterm infant's birth (Edinburgh Postnatal Depression Scale, EPDS), then for stress (Parental Stressor Scale: Neonatal Intensive Care Unit, PSS:NICU), and attachment (Maternal Postnatal Attachment Scale, MPAS) at infant's term-equivalent age. Data were compared with 14 mothers recruited between November 2020 and June 2021 during the COVID-19 pandemic. No significant differences were found in the scores for depression, stress, and attachment between the two groups. However, a non-statistically significant trend showed a general increase of depression symptoms in mothers during the COVID-19 pandemic, which significantly correlated to the attachment and stress scores. Moreover, the PSS:NICU Sights and Sounds score was significantly positively correlated with EPDS scores and negatively with the MPAS score only in the During-COVID group. To conclude, we discussed a possible dampened effect of the several protective family-based actions that have been adopted in the Geneva University Hospital during the health crisis, and we discussed the most appropriate interventions to support parents in this traumatic period during the COVID-19 pandemic.

A self-comfort oriented pattern of regulatory behavior and avoidant attachment are more likely among infants born moderate-to-late preterm

Infants born preterm (<37 gestational weeks, GW) are at increased risk for regulatory difficulties and insecure attachment. However, the association between infants' regulatory behavior patterns and their later attachment organization is understudied in the preterm population. We addressed this gap by utilizing a Portuguese sample of 202 mother-infant dyads. Specifically, we compared the regulatory behavior patterns of 74 infants born moderate-to-late preterm (MLPT, 32-36 GW) to those of 128 infants born full-term (FT, 37-42 GW) and evaluated the associations of these regulatory patterns with later attachment. Infants' regulatory behavior patterns (Social-Positive Oriented, Distressed-Inconsolable, or Self-Comfort Oriented) were evaluated in the Face-to-Face-Still-Face paradigm at 3 months, and their attachment organization (secure, insecure-avoidant, or insecure-ambivalent) was evaluated in the Strange Situation at 12 months corrected age. In both samples, the Social-Positive-Oriented regulatory pattern was associated with secure attachment; the Distressed-Inconsolable pattern with insecure-ambivalent attachment; and the Self-Comfort-Oriented pattern with insecure-avoidant attachment. However, compared to FT infants, infants born MLPT were more likely to exhibit a Self-Comfort-Oriented pattern and avoidant attachment. Most perinatal and demographic variables were not related to infant outcomes. However, infants with a higher 1-min Apgar were more likely to exhibit the Social-Positive-Oriented regulatory pattern and secure attachment.
