Maternal-fetal attachment, parenting stress during infancy, and child outcomes at age 3 years.

Maternal-fetal attachment (MFA), a woman's relationship with and affiliative behaviors toward her unborn child, has been linked to near-term infant physical and developmental outcomes. However, further longitudinal research is needed to understand whether the impact of MFA extends past the earliest years of life. The current study explored relationships between MFA and child socioemotional competence and behavior problems at age 3 and whether parenting stress mediated the association between MFA and child outcomes. Data were collected from 221 primarily Black/African-American mothers who completed a scale of MFA during pregnancy. Mothers reported on parenting stress at infant age 7 months and reported on child socioemotional competence and problem behaviors at child age 3 years. In path analyses, MFA was directly associated with child socioemotional competence at age 3 years, but an indirect association between MFA and socioemotional competence via parenting stress was not significant. We also observed a significant indirect association between lower MFA and child internalizing behavior problems via parenting stress that was related to maternal dissatisfaction regarding interactions with her child. Findings suggest that assessing MFA may serve as a means to identify dyads who would benefit from support to promote individual health outcomes.

La afectividad materno-fetal (MFA), la relación y comportamientos de afiliación de una mujer hacia su niño en el vientre, ha sido conectada a los resultados físicos y de desarrollo del infante cuya gestación está cerca al término. Sin embargo, se necesita investigación longitudinal adicional para comprender si el impacto de MFA se extiende más allá de los más tempranos años de vida. El presente estudio exploró las relaciones entre MFA y la competencia socioemocional y problemas de comportamiento del niño a la edad de 3 años y si el estrés de crianza medió la asociación entre MFA y los resultados en el niño. Se recogió información de 221 madres, primariamente negras/afroamericanas, que completaron una escala de MFA durante el embarazo. Las madres reportaron sobre el estrés de crianza cuando el infante tenía 7 meses y reportaron sobre la competencia socioemocional y los problemas de comportamiento del niño cuando éste tenía 3 años. En análisis de trayectoria, se asoció MFA directamente con la competencia socioemocional del niño a la edad de 3 años, pero una asociación indirecta entre MFA y la competencia socioemocional por medio del estrés de crianza no fue significativa. También observamos una significativa asociación indirecta entre MFA y la internalización de problemas del comportamiento por parte del niño vía el estrés de crianza que se relacionó con la insatisfacción materna en cuanto a las interacciones con su niño. Los resultados indican que evaluar MFA pudiera servir como un medio de identificar díadas que se beneficiarían del apoyo para promover resultados de salud individuales.

L'attachement maternel foetal (Maternal-fetal attachment, soit MFA), une relation de la femme avec son enfant à naître et des comportements affiliatifs envers l'enfant à naître, a été lié à des résultats physiques et développementaux du bébé quasiment à terme. Cependant des recherches longitudinales plus approfondies sont nécessaires afin de comprendre si l'impact du MFA dépasse les premières années de la vie. Cette étude a exploré les relations entre le MFA et la compétence socio-émotionnelle de l'enfant et les problèmes de comportement à l'âge de trois ans et si le stress de parentage affectait l'association entre le MFA et les résultats sur l'enfant. Les données ont été recueillies à partir de 221 mères américaines majoritairement noires/afro-américaines qui ont rempli l'échelle du MFA durant la grossesse. Les mères ont fait état de stress de parentage à l'âge de 7 mois pour le bébé et répondu à des questions sur la compétence socio-émotionnelle de l'enfant et les problèmes de comportement à l'âge de 3 ans. Dans les analyses de trajectoire le MFA était directement lié à la compétence socio-émotionnelle de l'enfant à l'âge de 3 ans, mais un lien indirect entre le MFA et la compétence socio-émotionnelle à travers le stress de parentage n'était pas important. Nous avons aussi observé un lien indirect important entre le MFA et les problèmes de comportement d'internalisation de l'enfant au travers du stress de parentage qui était lié à l'insatisfaction maternelle concernant les interactions avec son enfant. Les résultats suggèrent que l'évaluation du MFA peut servir de moyen d'identifier des dyades qui bénéficierait d'un soutien pour promouvoir des résultats de santé individuels.

Frontal Alpha Asymmetry in Response to Stressor Moderates the Relation Between Parenting Hassles and Child Externalizing Problems.

Inequitable urban environments are associated with toxic stress and altered neural social stress processing that threatens the development of self-regulation. Some children in these environments struggle with early onset externalizing problems that are associated with a variety of negative long-term outcomes. While previous research has linked parenting daily hassles to child externalizing problems, the role of frontal alpha asymmetry (FAA) as a potential modifier of this relationship has scarcely been explored. The present study examined mother-child dyads, most of whom were living in low socioeconomic status households in an urban environment and self-identified as members of racial minority groups. Analyses focused on frustration task electroencephalography (EEG) data from 67 children (mean age = 59.0 months, SD = 2.6). Mothers reported the frequency of their daily parenting hassles and their child's externalizing problems. Frustration task FAA moderated the relationship between parenting daily hassles and child externalizing problems, but resting FAA did not. More specifically, children with left frontal asymmetry had more externalizing problems as their mothers perceived more hassles in their parenting role, but parenting hassles and externalizing problems were not associated among children with right frontal asymmetry. These findings lend support to the motivational direction hypothesis and capability model of FAA. More generally, this study reveals how individual differences in lateralization of cortical activity in response to a stressor may confer differential susceptibility to child behavioral problems with approach motivation (i.e., left frontal asymmetry) predicting externalizing problems under conditions of parental stress.

Miswiring the brain: Human prenatal Δ9-tetrahydrocannabinol use associated with altered fetal hippocampal brain network connectivity.

Increasing evidence supports a link between maternal prenatal cannabis use and altered neural and physiological development of the child. However, whether cannabis use relates to altered human brain development prior to birth, and specifically, whether maternal prenatal cannabis use relates to connectivity of fetal functional brain systems, remains an open question. The major objective of this study was to identify whether maternal prenatal cannabis exposure (PCE) is associated with variation in human brain hippocampal functional connectivity prior to birth. Prenatal drug toxicology and fetal fMRI data were available in a sample of 115 fetuses [43 % female; mean age 32.2 weeks (SD = 4.3)]. Voxelwise hippocampal connectivity analysis in a subset of age and sex-matched fetuses revealed that PCE was associated with alterations in fetal dorsolateral, medial and superior frontal, insula, anterior temporal, and posterior cingulate connectivity. Classification of group differences by age 5 outcomes suggest that compared to the non-PCE group, the PCE group is more likely to have increased connectivity to regions associated with less favorable outcomes and to have decreased connectivity to regions associated with more favorable outcomes. This is preliminary evidence that altered fetal neural connectome may contribute to neurobehavioral vulnerability observed in children exposed to cannabis in utero.
