Emotional-Behavioral Regulation, Temperament and Parent-Child Interactions Are Associated with Dopamine Transporter Allelic Polymorphism in Early Childhood: A Pilot Study

COMT Val158Met polymorphism protects the impact of a mother's history of childhood trauma on emotional and behavioural problems in preschool children

Childhood trauma has a well-established negative impact on mental health outcomes across the lifespan. Cumulative evidence suggests an intergenerational transmission of trauma to descendants. In this way, considering the child's COMT Val158Met (rs4680: G > A) variant, the study aims to investigate the interactive effect of maternal childhood trauma on the emotional/behavioural problems of their offspring in preschoolers age (4-5 and 11 years old) from a population-based dyad of pregnant adolescent women. The behaviour problems of 310 children were assessed using the Child Behaviour Checklist (CBCL) instrument, and maternal trauma was assessed with the Child Trauma Questionnaire (CTQ) between the 20 to 22° gestational weeks. Maternal childhood trauma increases the risk for all emotional/behavioural problems in the offspring, and no direct association between the child's Val158Met genotypes with emotional/behavioural problems. Interestingly, in moderation analysis adjusted by sex, age and skin colour, children of mothers exposed to childhood trauma, carrying the Val/Met genotype, are less likely to develop externalising (p = .020) and total problems (p = .041) when compared to homozygous (Val/Val and Met/Met). Thus, our findings reinforce evidence on the intergenerational impact of maternal trauma on emotional/behavioural problems and demonstrate that this risk is influenced by the genetic background of the individual, varying according to the functional COMT genotype, which confers a protective profile for the development of externalising and total problems.

Longitudinal associations between psychosomatic and emotional status and selected food portion sizes in European children and adolescents: IDEFICS/I.Family study

This study aims to investigate the influence of psychosomatic and emotional status on food portion sizes (PSs) consumption from high energy-dense food groups in European children and adolescents. We hypothesized that psychosomatic and emotional status would have a significant association with the PS selection of energy-dense food. The study included 7355 children aged between 2 and 9.9 years at baseline (T0) (48.8% females); 3869 after 2 years (T1) (48.2% females), and 2971 (51.8% females) after 6 years of follow-up (T3). Psychosomatic and emotional status were measured using emotional well-being during the last week score (KINDL) and Strengths and Difficulties Questionnaire. PS was calculated from daily food intake recorded in 24-hour dietary recalls. The associations between emotional status indicators and PS from selected energy-dense food groups were assessed by multilevel linear regression models. In the cross-sectional analysis, we observed that higher KINDL scores were linked to lower PS consumption from sweet bakery products and savory snacks in both genders. Moreover, we found that adolescent females with high emotional and peer problem scores tended to consume larger PS of carbohydrate-rich and sugar-fatty food items (P < .017). Longitudinally, higher peer problem scores were associated with increased PS from bread and rolls, margarine and lipids, and dairy products in all genders and age groups (P< .017). In adolescents, psychosomatic and emotional status could be a trigger for consuming large PS from carbohydrate-rich and sugar-fatty energy-dense foods. Thus, nutritional interventions should consider emotional status to decrease unhealthy dietary habits in children and adolescents.

Binge-Eating Precursors in Children and Adolescents: Neurodevelopment, and the Potential Contribution of Ultra-Processed Foods

Binge-eating disorder (BED) is a highly prevalent disorder. Subthreshold BED conditions (sBED) are even more frequent in youth, but their significance regarding BED etiology and long-term prognosis is unclear. A better understanding of brain findings associated with BED and sBED, in the context of critical periods for neurodevelopment, is relevant to answer such questions. The present narrative review starts from the knowledge of the development of emotional self-regulation in youth, and the brain circuits supporting emotion-regulation and eating behaviour. Next, neuroimaging studies with sBED and BED samples will be reviewed, and their brain-circuitry overlap will be examined. Deficits in inhibition control systems are observed to precede, and hyperactivity of reward regions to characterize, sBED, with overlapping findings in BED. The imbalance between reward/inhibition systems, and the implication of interoception/homeostatic processing brain systems should be further examined. Recent knowledge of the potential impact that the high consumption of ultra-processed foods in paediatric samples may have on these sBED/BED-associated brain systems is then discussed. There is a need to identify, early on, those sBED individuals at risk of developing BED at neurodevelopmental stages when there is a great possibility of prevention. However, more neuroimaging studies with sBED/BED pediatric samples are needed.

Parental Postnatal Depression in the Time of the COVID-19 Pandemic: A Systematic Review of Its Effects on the Parent-Child Relationship and the Child's Developmental Outcomes

The international literature has shown that maternal and paternal postnatal depression (PND) is one of the most common mental illnesses in the perinatal period, with significant consequences for parent-infant relationships and infant development. The COVID-19 pandemic has increased the rates of prevalence of PND, exacerbating the mental health risk for new families. This systematic review aims to examine the effect of maternal and paternal PND on parent-infant relationships and children's development in the first 36 months after childbirth during the COVID-19 outbreak. Eligible studies were identified using the following databases: Medline, CINAHL, SCOPUS, PsycINFO, PsycARTICLES, ScienceDirect, and Web of Science. Of the 1252 studies considered, 10 studies met the inclusion criteria. Results showed that maternal PND significantly affected the quality of the early mother-infant relationship and the infant's motor, self-regulation, and socio-emotional development. In addition, the detrimental impact of maternal PND on the quality of early mother-infant relationships seems to become stronger as COVID-19 concerns increase. No studies included fathers. These findings strengthened the importance of planning targeted prevention and treatment strategies to prevent PND and its short- and long-term consequences, especially in the case of stressful and traumatic events. They also suggested the urgent need for further exploration of fathers.

Impact of Maternal-Newborn Separation in Italian Women with Suspected COVID-19 Infection on Psychopathological Symptoms and Quality of Interactions during Breastfeeding

INTRODUCTION

Before the COVID-19 pandemic, proximity between mothers and their newborn infants was at the core of sanitary guidelines. With the aim of stopping the virus transmission from mothers to infants and possible physical dangers due to the infection, some hospitals discouraged or even prohibited skin-to-skin contact and breastfeeding.

METHOD

This study recruited 180 dyads in private and public hospitals in Italy with the aim of verifying whether mother-infant separation after delivery is associated with higher maternal psychopathological distress (assessed through the SCL-90-R) and poorer quality of dyadic interactions during breastfeeding (evaluated through the SVIA).

RESULTS

Our results showed that mothers separated from their infants displayed more anxiety, depression, and obsessive-compulsive symptoms and a lower quality of feeding interactions on all the subscales of the SVIA (mother's affective state; interactive conflict; food refusal behavior; dyad's affective state).

CONCLUSION

In light of these results, our study suggests that separating mothers from their newborns is associated with increased psychopathological symptoms in mothers and poorer feeding interactions. These issues have been posited as key predictors of maladaptive outcomes in infants' later lives; therefore, health services must fully consider the short- and long-term consequences of separating mothers and infants in their policies in the event of future pandemics.

Observational Tools Using Video Recordings of Parent-Child Feeding Interactions: A Narrative Review

Current research has confirmed that the quality of the caregiver-child relationship influences the child's emotional and behavioral development. Play and feeding contexts, for example, are the best contexts to observe mother-child or father-child interaction. The observation of feeding interaction establishes involvement on the part of both parties and identifies relationship characteristics. The purpose of this study is to select and describe the most frequently used observational methods during feeding interactions in the first three years of a child's life. Instruments that employ video recordings of mealtimes will be detailed to highlight the relevance that specific tools have nowadays. Finally, the SVIA (Scala di Valutazione delle Interazioni Alimentari), a technique for analyzing food interactions by observation that has also been utilized remotely, will be offered. This is intended to provide practitioners and researchers with an overview of tools while also taking into consideration the present scenario in which digital tools are increasingly being employed in health and clinical settings. Furthermore, the purpose of this paper is to review the various observational methods of the parent-child relationship to assist future practitioners and researchers in the field in making an accurate assessment of caregiver-child interaction and selecting a valid tool for the early recognition of problematic relationships and identifying the most appropriate treatment modalities.

Children’s ADHD and Dysregulation Problems, DAT1 Genotype and Methylation, and their Interplay with Family Environment

Background

International literature has underlined the complex interplay between genetic and environmental variables in shaping children’s emotional-behavioral functioning.

Objective

This study aimed to explore the dynamic relationship between children’s Dopamine Transporter (DAT1) genotype and methylation, and maternal and paternal affective environment, on children’s Attention Deficit Hyperactivity Disorder (ADHD) problems and dysregulation problems.

Method

In a community sample of 76 families with school-aged children, we assessed children’s DAT1 genotype and methylation, their own ADHD problems and dysregulation profile (CBCL 6–18 DP), and maternal and paternal psychopathological risk, parenting stress, and marital adjustment. Hierarchical regressions were carried out to verify the possible moderation of children’s genotype on the relationship between children’s methylation and psychopathological risk, parental environment and children’s methylation, and parental environment and children’s psychopathological risk.

Results

The levels of methylation at M1 CpG significantly predicted ADHD problems among children with 10/10 genotype, whereas high levels of methylation at M6 CpG predicted low ADHD problems for children with 9/x genotype. High levels of methylation at M3 CpG were associated with high scores of CBCL DP. DAT1 genotype moderated the relationship between maternal and paternal variables with children’s methylation and psychopathological risk. The scores of maternal and paternal Dyadic Adjustment Scale showed indirect effects on children’s methylation and psychopathological risk in relation to those exerted by risk factors.

Conclusion

Our study has supported the emerging evidence on the complex nature of children’s emotional-behavioral functioning and the associated risk and protective factors, with important implications for the planning of preventive programs.

The COVID-19 Pandemic and Its Impact on Families' Mental Health: The Role Played by Parenting Stress, Parents' Past Trauma, and Resilience

International research has evidenced the psychological impact of the COVID-19 pandemic on families, and the key role played by parenting stress levels. Although significant associations with parents' past trauma and resilience have been shown, this study aimed to explore their complex interplay on the relationship between parents' peritraumatic distress due to COVID-19, parenting stress, and children's psychopathological difficulties. We recruited 353 parents with children aged two to 16 years via an online survey during the Italian second wave of COVID-19. Parents' peritraumatic distress due to COVID-19, parenting stress, past trauma and resilience, and children's psychological difficulties were assessed through self-report and report-form questionnaires. Parents' past traumas significantly predicted peritraumatic distress due to COVID-19 and children's psychological difficulties. The relationship between past traumas and children's psychological difficulties was serial mediated by parents' peritraumatic distress and parenting stress. Direct and total effects of parent's resilience on parent's peritraumatic distress were not significant, but there were significant indirect effects via parenting stress and via parents' peritraumatic distress and parenting stress, indicating inconsistent mediation. This study evidenced the key risk and protective role played by, respectively, parents' past traumas exposure and resilience on the relationship between parents' psychological difficulties due to COVID-19, parenting stress, and children's psychological difficulties, with important clinical implications.

DAT1 and Its Psychological Correlates in Children with Avoidant/Restrictive Food Intake Disorder: A Cross-Sectional Pilot Study

International research has underlined the role played by children’s and maternal psychopathological symptoms on the onset of avoidant/restrictive food intake disorder (ARFID) in early childhood. No study has considered the possible interplay between children’s dopamine transporter (DAT1) genotype and methylation, dysregulation problems and maternal psychopathological risk. This study aimed to investigate the complex relationship between these variables, considering the possible mediation role played by children’s DAT1 methylation on the relationship between mothers’ psychopathological risk and children’s dysregulation problems, moderated by children’s DAT1 genotype. Our sample consisted of 94 early children and their mothers, divided into four subgroups, based on children’s ARFID subtypes (irritable/impulsive (I/I), sensory food aversions (SFA), post-traumatic feeding disorders subtypes (PTFD), and a non-clinical group (NC)). We addressed children’s dysregulation problems and maternal psychopathological risk, and collected children’s DNA through buccal swabs. Results showed that children’s 9/x genotype was associated with PTFD and NC groups, whereas the 10/10 genotype was associated with the SFA group, with large effect size. There were significant large differences in the study groups on children’s DAT1 total methylation, children’s dysregulation problems, and maternal psychopathological risk. Children’s DAT1 methylation did not mediate the relationship between mother’s psychopathological risk and children’s dysregulation problems, but there was a significant large direct effect. Children’s 9/x genotype moderated the relationship between maternal psychopathological risk and children’s DAT1 methylation but, respectively, with a large and small effect. Our pilot study suggested that the relationship between children’s DAT1 genotype and methylation, dysregulation problems, and maternal psychopathological risk has a crucial contribution to ARFID.
