Variation in the mu-opioid receptor gene (OPRM1) moderates the influence of maternal sensitivity on child attachment.

The endogenous opioid system is thought to play an important role in mother-infant attachment. In infant rhesus macaques, variation in the µ-opioid receptor gene (OPRM1) is related to differences in attachment behavior that emerges following repeated separation from the mother; specifically, infants carrying at least one copy of the minor G allele of the OPRM1 C77G polymorphism show heightened and more persistent separation distress, as well as a pattern of increased contact-seeking behavior directed towards the mother during reunions (at the expense of affiliation with other group members). Research in adult humans has also linked the minor G allele of the analogous OPRM1 A118G polymorphism with greater interpersonal sensitivity. Adopting an interactionist approach, we examined whether OPRM1 A118G genotype and maternal (in)sensitivity are associated with child attachment style, predicting that children carrying the G allele may be more likely to develop an ambivalent attachment pattern in response to less sensitive maternal care. The sample consisted of 191 mothers participating with their children (n = 223) in the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) project, a community-based, birth cohort study of Canadian mothers and their children assessed longitudinally across the child's development. Maternal sensitivity was coded from at-home mother-child interactions videotaped when the child was 18 months of age. Child attachment was assessed at 36 months using the Strange Situation paradigm. As predicted, G allele carriers, but not AA homozygotes, showed increasing odds of being classified as ambivalently attached with decreasing levels of maternal sensitivity. Paralleling earlier non-human animal research, this work provides support for the theory that endogenous opioids contribute to the expression of attachment behaviors in humans.

Maternal dispositional mindfulness and mother-child relationship: The mediating role of emotional control during parenting.

BACKGROUND: The literature supports the role of parental dispositional mindfulness on parent-child relationship quality. However, little is known about the connection between these two aspects. OBJECTIVE: The aim of this study was to investigate whether emotion regulation during parenting, that is, the ability to control negative emotions, mediated the association between parental dispositional mindfulness and parent-child relationship quality. The study also explored the moderation role of child age on the association between parental dispositional mindfulness and parent's ability to control negative emotions during parenting. METHODS: Participants were 635 mothers of children aged between 12 months and 5 years. Mothers completed self-report questionnaires to measure maternal dispositional mindfulness, mother-child relationship quality and maternal control of negative emotions during parenting. RESULTS: Results showed that maternal ability to control negative emotions during parenting partially mediated the association between maternal dispositional mindfulness and mother-child relationship quality. Moreover, the moderation role of child age indicated that the association between maternal dispositional mindfulness and maternal ability to control negative emotions during parenting was stronger for older children's mothers. CONCLUSION: Dispositional mindfulness has a protective role for the quality of parenting and the mother-child relationship. Theoretical and practical implications are discussed.

The relationship between maternal-infant bonding and postpartum depression/anxiety: moderating effect of childhood psychological abuse and validation of the Mother-to-Infant Bonding scale (MIBS-8) in Arabic.

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 Lebanon, there is a paucity of information about mother-infant bonding in the postpartum period. Given that Lebanese pregnant women constitute an important part of the population to look at, the objectives of the study were to (1) validate the Arabic version of the mother-infant bonding scale and (2) the relation between mother-infant bond and postpartum depression/anxiety; (3) the moderating effect of child abuse in the association between mother-infant bond and postpartum depression/anxiety. METHODS: This cross-sectional study was conducted from September 2022 until June 2023, enrolling 438 women 4-6 weeks after delivery (mean age: 31.23 ± 5.24 years). To examine the factor structure of the mother-infant bond scale, we used an Exploratory-Confirmatory (EFA-CFA) strategy. To check if the model was adequate, several fit indices were calculated: the normed model chi-square (χ2/df), the Steiger-Lind root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI). RESULTS: EFA was conducted on the first subsample. Three items were removed. The five items remaining loaded on one factor, which explained 73.03% of the common variance (ω = .91 / α = .90). After adding a correlation between residuals for items 2-7 and 5-8, fit indices of the CFA results were acceptable: χ2/df = 6.97/3 = 2.32, RMSEA = .068 (90% CI .001, .135), SRMR = .017, CFI = .996, TLI = .988. The interaction maternal-infant bonding by child psychological abuse was significantly associated with depression and anxiety respectively. At low, moderate and high levels of child psychological abuse, higher maternal-infant bonding scores (greater difficulty in bonding) were significantly associated with higher depression and higher anxiety respectively. CONCLUSION: This study provides, for the first time, a specific Arabic scale to assess mother-infant bonding reliably and validly. Furthermore, our study has suggested the existence of factors that have additive effects in potentiating the risk for depression and anxiety among Lebanese postpartum women, namely a history of psychological child abuse. Therefore, laborious awareness programs and healthcare services need to be implemented in order to prevent maternal mental health disorders from being unrecognized and left untreated.

Effects of cleft lip on visual scanning and neural processing of infant faces.

Infant faces readily capture adult attention and elicit enhanced neural processing, likely due to their importance evolutionarily in facilitating bonds with caregivers. Facial malformations have been shown to impact early infant-caregiver interactions negatively. However, it remains unclear how such facial malformations may impact early visual processing. The current study used a combination of eye tracking and electroencephalography (EEG) to investigate adults' early visual processing of infant faces with cleft lip/palate as compared to normal infant faces, as well as the impact cleft palate has on perceived cuteness. The results demonstrated a significant decrease in early visual attention to the eye region for infants with cleft palate, while increased visual attention is registered on the mouth region. Increased neural processing of the cleft palate was evident at the N170 and LPP, suggesting differences in configural processing and affective responses to the faces. Infants with cleft palate were also rated significantly less cute than their healthy counterparts (mean difference = .73, p < .001). These results suggest that infants' faces with cleft lip/palate are processed differently at early visual perception. These processing differences may contribute to several important aspects of development (e.g., joint attention) and may play a vital role in the previously observed difficulties in mother-infant interactions.

Interbrain substrates of role switching during mother-child interaction.

Mother-child interaction is highly dynamic and reciprocal. Switching roles in these back-and-forth interactions serves as a crucial feature of reciprocal behaviors while the underlying neural entrainment is still not well-studied. Here, we designed a role-controlled cooperative task with dual EEG recording to explore how differently two brains interact when mothers and children hold different roles. When children were actors and mothers were observers, mother-child interbrain synchrony emerged primarily within the theta oscillations and the frontal lobe, which highly correlated with children's attachment to their mothers (self-reported by mothers). When their roles were reversed, this synchrony was shifted to the alpha oscillations and the central area and associated with mothers' perception of their relationship with their children. The results suggested an observer-actor neural alignment within the actor's oscillations, which was related to the actor-toward-observer emotional bonding. Our findings contribute to the understanding of how interbrain synchrony is established and dynamically changed during mother-child reciprocal interaction.

Mother adversity and co-residence time impact mother-child similarity in genome-wide and gene-specific methylation profiles.

BACKGROUND: The effects of adverse life events on physical and psychological health, with DNA methylation (DNAm) as a critical underlying mechanism, have been extensively studied. However, the epigenetic resemblance between mother and child in the context of neglectful caregiving, and whether it may be shaped by the emotional impact of maternal stressful events and the duration of co-residence (indexed by child age), remains unknown. The present study examined mother-child similarity in methylation profiles, considering the potential effect of mother adversity, mother empathy, neglect-control group, child age (an index of years of mother-child co-residence), and mother age. Using Illumina Epic arrays, we quantified DNAm in 115 mother-child saliva samples. We obtained a methylation similarity index by computing correlation coefficients between methylation profiles within dyads, for the entire epigenome, and five specific genes related to stress and empathy: NR3C1, FKPB5, OXTR, SCL6A4, and BDNF. RESULTS: The methylation profiles of the mother-child familial pairs significantly correlated as compared to mother-child random pairs for the entire epigenome and NR3C1, FKBP5, OXTR and BDNF genes. Next, multiple linear regression models observed associations of mother adversity, child age, and neglect-control group on mother-child methylation similarity, only significant in mother-child familial pairs, after correcting for multiple comparisons. Higher mother adversity was associated with lower mother-child methylation similarity for the epigenome-wide analysis, for the BDNF gene, and in the neglect-control group for the OXTR gene. In turn, being an older child (longer co-residence) was associated with higher mother-child methylation similarity. CONCLUSIONS: Mother adversity and co-residence time are modulating factors in the intergenerational methylation process that offer a window into development-dependent adaptations that can be affected by both hereditary and environmental factors, significantly observed only in biological dyads. A twofold implication for child well-being emerges, one is positive in that children of mothers exposed to life adversity or neglect did not necessarily inherit their methylation patterns. The other is concerning due to the influence of time spent living together, which affects similarity with the mother and potentially increases the risk of inheriting an epigenetic profile associated with future dysfunctional parenting patterns. This underscores the importance of the 'the earlier, the better' recommendation by the Child Protection System, which is not always followed.

Perinatal depression trajectories and child development at one year: a study in China.

BACKGROUND: The objective of the current study was to investigate the correlation between trajectories of maternal perinatal depression (PND) spanning from early pregnancy to one year postpartum and developmental delays observed in one-year-old children. METHODS: The dataset under examination encompassed 880 women who took part in a mother-child birth study conducted in China. Latent class growth analysis (LCGA) was employed to identify patterns in Edinburgh Postnatal Depression Scale (EPDS) scores of women, spanning from early pregnancy to one year postpartum. To assess the neurodevelopment of one-year-old children, a Chinese version of the Bayley Scale of Infant Development (BSID-CR) was employed. Logistic regression was employed to explore the association between PND trajectories and developmental delays in children, with appropriate covariate adjustments. RESULTS: The trajectories of maternal PND identified in this study included a minimal-stable symptom group (n = 155), low-stable symptom group (n = 411), mild-stable symptom group (n = 251), and moderate-stable symptom group (n = 63). Logistic regression analysis revealed that mothers falling into the moderate-stable symptom group exhibited a notably heightened risk of having a child with psychomotor developmental delays at the age of one year. CONCLUSIONS: The findings drawn from a representative sample in China provide compelling empirical evidence that bolsters the association between maternal PND and the probability of psychomotor developmental delays in children. It is imperative to develop tailored intervention strategies and meticulously design mother-infant interactive intervention programs for women with PND.

Stroking in early mother-infant exchanges: The role of maternal tactile biography and interoceptive sensibility.

Caress-like is a crucial component of caregiving and a key factor in mother-infant interactions. Mother's experience of touch during her own childhood (i.e., tactile biography) has been found to be related to maternal actual use of caress-like touch (i.e., stroking) during mother-infant exchanges. Evidence also suggests that maternal interoceptive sensibility (i.e., self-perceived sensitivity to inner-body sensations) might be related to sensitive caregiving abilities. However, further empirical investigation is needed to understand to what extent tactile biography and interoceptive sensibility have an impact on mothers' stroking when interacting with their infants. Using an online survey, this cross-sectional study explored the potential association between maternal tactile biography, interoceptive sensibility and use of touch for interaction with their own infants in a group of 377 Italian mothers (mean age = 33.29; SD = 4.79). We tested and compared a series of multivariate linear mediation models using maternal tactile biography as predictor, maternal use of affective touch as outcome variable and Multidimensional Assessment of Interoceptive Awareness (MAIA) subscale scores as mediators. We found that, if a mother had positive touch experiences in her own childhood, she may be more likely to use touch in a positive and nurturing way with her own infant (i.e., stroking). Furthermore, mothers' interoceptive sensibility in the form of attention regulation, self-regulation and body listening mediates the association between their past experiences of positive touch and their use of caress-like touch in mother-infant exchanges. This study highlights that maternal tactile biography is directly associated with mothers' use of caress-like touch and indirectly linked to it through the mediating role of interoceptive sensibility.

Older mothers and their difficult adult children: a life course exploration.

Adult child to parent violence is a growing international social problem that needs to be better understood to develop clinical interventions. An exploratory study on the antecedents of early life adversity on adult child to parent violence/elder mistreatment was carried out using secondary analysis. Directed content analysis was used based on life course theory with a data set of older mothers all > 57 years old (J. R. Smith 2021, 2022). Measurement of instances of child abuse, domestic violence, and birth trauma among abused older mothers was conducted. All the older women had reported being negatively affected by their adult children's problems and 56% reported being physically attacked. A case example is presented to illustrate how repeated incidents of abuse or neglect in early life might explain an older woman's inability to take actions for her own safety.

Attentional bias to infant faces might be associated with previous care experiences and involvement in childcare in same-sex mothers / El sesgo de atención hacia los rostros de los bebés podría estar asociado con experiencias de cuidado previas y la participación en el cuidado infantil en madres del mismo sexo

Background: Attentional bias toward infant faces is associated with parental sensitivity and supports the infant-caregiver attachment relationship, ultimately fostering child health outcomes. However, experience-related determinants of parents' attentional bias to infant faces have been poorly investigated. We examined attentional bias to infant versus adult faces in a sample of same-sex mothers (N = 76), and whether it varied depending on maternal involvement in childcare and the perceived quality of past experiences of care. Method: A Go/no-Go attentional task was used to compare the effects of infant and adult faces in retaining attention. Maternal involvement in childcare was measured using items addressing nurturing behaviors. Memories of past experiences of care were collected using the short-form version of the Parental Acceptance-Rejection scale. Results: Results confirmed that infant faces induced greater attentional bias compared to adult faces. More involved mothers were more biased, in terms of attention, to infant versus adult faces. Attentional bias to infant versus adult faces increased as mothers felt more rejected by their own fathers during childhood. Discussion: Our findings suggested that attentional bias to infant faces might be associated with past experiences of care and direct commitment in childcare in same-sex mothers. Robust and accurate empirical findings on same-sex parent families are essential to inform social policies supporting these families’ well being.(AU)

Effect of Companion Presence during Skin-to-Skin Contact on Maternal Anxiety: A Randomized Clinical Trial.

OBJECTIVE: To compare the effect of companion presence versus midwife presence during skin-to-skin contact (SSC) at birth on maternal anxiety and satisfaction, and neonatal physiological parameters. METHODS: A randomized controlled trial was conducted on 92 pregnant women who were randomized to provide SSC to their newly borns for one hour postpartum, in the presence of a companion (study group) or a midwife (control group). Maternal anxiety (using the Visual Analogue Scale) and the neonatal physiological parameters (including temperature, heart rate, and oxygen saturation) were assessed in four stages viz., immediately after birth, and at 30, 60 and 90 minutes after birth. Maternal satisfaction was also evaluated after transferring the mother to the postpartum ward. RESULTS: We analyzed 86 mother-infant dyads (43 per group). Having a companion significantly reduced maternal anxiety after birth as compared to having a midwife at 30, 60, and 90 minutes after birth (P = 0.04, P = 0.01, and P = 0.04, respectively). There was also a small to medium effect size of the presence of companion compared to midwife in terms of maternal anxiety at 30 minutes (Cohen's d = 0.45; 95% CI = 0.02, 0.87), 60 minutes (Cohen's d = 0.52; 95% CI = 0.08, 0.94) and 90 minutes after birth (Cohen's d = 0.45; 95% CI = 0.02, 0.88). However, there was no significant effect of the same on neonatal physiological parameters. Having a companion versus a midwife led to higher maternal satisfaction rates (P = 0.02); 65.1% of mothers in the study group and 37.2% of mothers in the control group were desirous of the same care in future (P = 0.02). CONCLUSION: Companion presence during SSC leads to a significant reduction in maternal anxiety compared to midwife presence.

The Impact of Postpartum Depression on the Early Mother-Infant Relationship during the COVID-19 Pandemic: Perception versus Reality.

Postpartum depression (PPD) can interfere with the establishment of affective bonds between infant and mother, which is important for the cognitive, social-emotional, and physical development of the child. Rates of PPD have increased during the COVID-19 pandemic, likely due to the added stress and limited support available to new parents. The present study examined whether parenting-related stress, perceived bonding impairments, the quality of observed mother-infant interactions, and salivary oxytocin levels differ between depressed and non-depressed mothers, along with differential impacts of COVID-19 on depressed mothers. Participants included 70 mothers (45 depressed, 25 controls) with infants aged 2-6 months. All data were collected remotely to ease participant burden during the pandemic. Depression was associated with experiences of heightened parenting-related stress and bonding difficulties. These differences were not observed during mother-infant interactions or in salivary oxytocin levels. Differences in COVID-19-related experiences were minimal, though depressed mothers rated slightly higher stress associated with returning to work and financial impacts of the pandemic. Findings highlight the importance of early intervention for PPD to mitigate long-term effects on mothers, children, and families. Additionally, they underscore the need for early intervention to support the developing mother-infant dyad relationship during this crucial time.

Skin-to-Skin Contact and Breastfeeding After Planned Cesarean Birth Before and During the COVID-19 Pandemic.

Background: Benefits of early skin-to-skin contact (SSC) between mother and newborn are widely documented, including improved breastfeeding outcomes. While promoting immediate SSC is standard practice for vaginal birth, it happens less often after cesarean birth. It is not known how changes in hospital practices and staffing shortages during the COVID-19 pandemic have influenced the practice of SSC in the operating room (OR). This study aims to identify the relationship between SSC after cesarean birth and breastfeeding and compare SSC before and during the COVID-19 pandemic at a single institution. Materials and Methods: This was a retrospective cohort study of 244 subjects who had scheduled cesarean births during 2019 and 2020. The primary outcome was newborn feeding at hospital discharge. Secondary outcomes were time to initiate breastfeeding, newborn feeding at 4-8-weeks postpartum, and location of SSC initiation in 2019 versus 2020. Results: SSC within 3 days of birth was significantly associated with feeding type on discharge and/or 4-8 weeks postpartum. More subjects intending to exclusively breastfeed met this intention at discharge with SSC in the OR. Newborns who had SSC in the OR had significantly earlier initiation of breastfeeding. There was an increase in SSC in the OR between 2019 (27%) and 2020 (39%). Conclusion: SSC in the OR was associated with improved short-term breastfeeding outcomes in our study. If immediate SSC is not possible, SSC within 3 days of birth may have breastfeeding benefits. The increase in SSC in the OR during the COVID-19 pandemic indicates that SSC practices can be implemented, despite challenging circumstances.

Effects of sociocultural stressors on maternal responsivity and the infant behavioral and neuroendocrine response to stress in families of Mexican descent.

Maternal stress is consistently linked to alterations in maternal behavior and infant neurodevelopmental outcomes. As the Latino population grows in the U.S., it is increasingly important to understand how culturally relevant factors affect this relationship. This study aimed to address the role of sociocultural stressors on maternal sensitivity and markers of infant emotional regulation and the neuroendocrine response to stress in mother/infant dyads of Mexican descent. Pregnant women of Mexican descent (n = 115) were recruited during early pregnancy and followed until their infants were 6 months old. Mothers completed measures of sociocultural stressors (acculturative stress and discrimination) at pre and postnatal time points. At 6 months, dyads underwent the Still Face procedure. Mothers were observed for behaviors exhibiting maternal responsivity, while negative vocalizations were observed in infants. Salivary cortisol was also collected from infants. Maternal responsivity was a salient risk factor for alterations in infant emotional regulation and cortisol activity. Postnatal experiences of discrimination were also negatively associated with infant negative affect. This work highlights maternal responsivity and points to a potential role for experiences of discrimination in the response to stress in the mother/child dyad that may have consequences for the development of emotional regulation in infants of Mexican descent.

Disentangling the link between maternal influences on birth weight and disease risk in 36,211 genotyped mother-child pairs.

Epidemiological studies have robustly linked lower birth weight to later-life disease risks. These observations may reflect the adverse impact of intrauterine growth restriction on a child's health. However, causal evidence supporting such a mechanism in humans is largely lacking. Using Mendelian Randomization and 36,211 genotyped mother-child pairs from the FinnGen study, we assessed the relationship between intrauterine growth and five common health outcomes (coronary heart disease (CHD), hypertension, statin use, type 2 diabetes and cancer). We proxied intrauterine growth with polygenic scores for maternal effects on birth weight and took into account the transmission of genetic variants between a mother and a child in the analyses. We find limited evidence for contribution of normal variation in maternally influenced intrauterine growth on later-life disease. Instead, we find support for genetic pleiotropy in the fetal genome linking birth weight to CHD and hypertension. Our study illustrates the opportunities that data from genotyped parent-child pairs from a population-based biobank provides for addressing causality of maternal influences.

Time-sensitive changes in the maternal brain and their influence on mother-child attachment.

Pregnancy and the postpartum period are characterized by an increased neuroplasticity in the maternal brain. To explore the dynamics of postpartum changes in gray matter volume (GMV), magnetic resonance imaging was performed on 20 healthy postpartum women immediately after childbirth and at 3-week intervals for 12 postpartum weeks. The control group comprised 20 age-matched nulliparous women. The first 6 postpartum weeks (constituting the subacute postpartum period) are associated with decreasing progesterone levels and a massive restructuring in GMV, affecting the amygdala/hippocampus, the prefrontal/subgenual cortex, and the insula, which approach their sizes in nulliparous women only around weeks 3-6 postpartum. Based on the amygdala volume shortly after delivery, the maternal brain can be reliably distinguished from the nulliparous brain. Even 12 weeks after childbirth, the GMV in the dorsomedial prefrontal cortex, and the cortical thickness of the subgenual and lateral prefrontal cortices do not reach the pre-pregnancy levels. During this period, a volume decrease is seen in the cerebellum, the thalamus, and the dorsal striatum. A less hostile behavior toward the child at 6-12 weeks postpartum is predicted by the GMV change in the amygdala, the temporal pole, the olfactory gyrus, the anterior cingulate, the thalamus and the cerebellum in the same period. In summary, the restructuring of the maternal brain follows time-dependent trajectories. The fact that the volume changes persist at 12 weeks postpartum indicates that the maternal brain does not fully revert to pre-pregnancy physiology. Postpartum neuroplasticity suggests that these changes may be particularly significant in the regions important for parenting.

Parental Responsivity and Child Communication During Mother-Child and Father-Child Interactions in Fragile X Syndrome.

PURPOSE: Past research shows that parentally responsive behavior toward the child positively influences language development in both neurotypical children and children with intellectual and developmental disabilities, including those with fragile X syndrome (FXS); however, most studies have focused exclusively on the mother-child relationship. The current study examined relationships between parent behavior (i.e., responsivity and behavior management) and child language performance in both mother-child and father-child interactions, as well as relationships between child characteristics and both parent behavior and child language. METHOD: Participants were 23 families of young boys with FXS between 3 and 7 years of age. Mothers and fathers independently completed questionnaires assessing child characteristics and separately engaged in 12-min play-based interactions with their child via telehealth. One parent also completed a comprehensive interview assessing child adaptive behavior. Video recordings of the parent-child interactions were transcribed and coded for parent and child behavior, and measures of parent and child language were obtained from the transcripts. RESULTS: Mothers and fathers used similar rates of responsive behaviors during parent-child interactions, and parental responsivity was positively associated with some aspects of child language performance (i.e., talkativeness and lexical diversity). Parental behavior, however, was not associated with syntactic complexity. Older children and children with higher levels of adaptive behavior had parents who used higher rates of responsive behaviors. Fathers used higher rates of behavior management strategies compared to mothers, and this type of parent behavior was not associated with child language. CONCLUSION: Overall, this study provides evidence that interventions focused on increasing parental responsiveness would be beneficial for families of children with FXS and that these interventions should be delivered early given the association between responsivity and child age.

Designing and evaluating a Nutritional Assessment and Intervention Kiosk for mother-child dyad to combat double burden of malnutrition.

The study protocol focuses on DBM, proposing a preventive strategy for mother-child pairs that would be accessible, affordable, sustainable, and human-centred. The aim is to guide the development of tools and technologies, passing through stages for gathering a process and presenting health data. The initial stage identifies the rules and models synthesising existing digital interventions combating forms of malnourishment, followed by designing and developing a Nutrition Informatics Intervention, i.e. NAIK. The last stage includes evaluation of the effectiveness and utility of NAIK. The system aims to address malnutrition by assessing different associated elements, with the participants. An SMS system will provide follow-up assistance. Overall, this study is an amalgamation of technology, data collection, personalised interventions, growth monitoring, and education to address malnutrition effectively by promoting positive health-behaviours within the community. So, a computerised health kiosk will help provide preventive strategies from the healthcare professional, especially in circumstances requiring immediate attention.

Mother-infant self- and interactive contingency at four months and infant cognition at one year: A view from microanalysis.

Although a considerable literature documents associations between early mother-infant interaction and cognitive outcomes in the first years of life, few studies examine the contributions of contingently coordinated mother-infant interaction to infant cognitive development. This study examined associations between the temporal dynamics of the contingent coordination of mother-infant face-to-face interaction at 4 months and cognitive performance on the Bayley Scales of Infant Development at age one year in a sample of (N = 100) Latina mother-infant pairs. Split-screen videotaped interactions were coded on a one second time base for the communication modalities of infant and mother gaze and facial affect, infant vocal affect, and mother touch. Multi-level time-series models evaluated self- and interactive contingent processes in these modalities and revealed 4-month patterns of interaction associated with higher one-year cognitive performance, not identified in prior studies. Infant and mother self-contingency, the moment-to-moment probability that the individual's prior behavior predicts the individual's future behavior, was the most robust measure associated with infant cognitive performance. Self-contingency findings showed that more varying infant behavior was optimal for higher infant cognitive performance, namely, greater modulation of negative affect; more stable maternal behavior was optimal for higher infant cognitive performance, namely, greater likelihood of sustaining positive facial affect. Although interactive contingency findings were sparse, they showed that, when mothers looked away, or dampened their faces to interest or mild negative facial affect, infants with higher 12-month cognitive performance were less likely to show negative vocal affect. We suggest that infant ability to modulate negative affect, and maternal ability to sustain positive affect, may be mutually reinforcing, together creating a dyadic climate that is associated with more optimal infant cognitive development.

Postpartum depression: Impact on pregnant women and the postnatal physical, emotional, and cognitive development of their children. An ecological perspective. / Depresión puerperal: impacto en la madre gestante y en el desarrollo físico, emocional y cognitivo posnatal de sus hijas/os. Una mirada ecológica.

Maternal mental health problems during pregnancy, childbirth, and the postpartum period are a challenge for public health. Not recognizing them hinders a timely diagnosis and treatment and has an impact on the mother and the establishment of the fundamental bond of the mother-child dyad. We must recognize the risk factors (age, socioeconomic status, mental health history, family dysfunction, unfavorable environment), clinical manifestations, and screening tools. There is evidence that the effect of stress, anxiety, and depression during pregnancy negatively affect fetal neurodevelopment and condition child developmental outcomes. Here we describe the negative impact of postpartum depression during the first months of life, which affects mother-child bonding, postnatal development (emotional, behavioral, cognitive, language), and the maintenance of breastfeeding. We also recognize protective factors that mitigate its effects. It is essential to establish preventive strategies and interdisciplinary diagnostic and therapeutic approaches to minimize the risks to the mother and her children.

Los problemas de salud mental materna durante el embarazo, parto y puerperio son un desafío para la salud pública. Su falta de reconocimiento atenta contra el diagnóstico y tratamientos oportunos, e impacta en la madre y el establecimiento del vínculo fundamental del binomio. Debemos reconocer los factores de riesgo (edad, situación socioeconómica, antecedentes psicopatológicos, disfunción familiar, entorno desfavorable), las manifestaciones clínicas y las herramientas de detección. Existen evidencias de que el efecto del estrés, la ansiedad y la depresión durante el embarazo afectan negativamente el neurodesarrollo fetal y condicionan los resultados del desarrollo infantil. Describimos el impacto negativo de la depresión puerperal durante los primeros meses de vida, que afecta el vínculo madre-hija/o, el desarrollo posnatal (emocional, conductual, cognitivo, lenguaje) y el mantenimiento de la lactancia materna. También reconocemos factores protectores que atemperan sus efectos. Es fundamental establecer estrategias preventivas y abordajes diagnósticos y terapéuticos interdisciplinarios para minimizar los riesgos sobre la madre y sus hijas/os.
