Sex differences in the association between maternal depression and child and adolescent cognitive development: a systematic review and meta-analysis

Current perspectives on perinatal mental health and neurobehavioral development: focus on regulation, coregulation and self-regulation

PURPOSE OF REVIEW

Perinatal mental health research provides an important perspective on neurobehavioral development. Here, we aim to review the association of maternal perinatal health with offspring neurodevelopment, providing an update on (self-)regulation problems, hypothesized mechanistic pathways, progress and challenges, and implications for mental health.

RECENT FINDINGS

(1) Meta-analyses confirm that maternal perinatal mental distress is associated with (self-)regulation problems which constitute cognitive, behavioral, and affective social-emotional problems, while exposure to positive parental mental health has a positive impact. However, effect sizes are small. (2) Hypothesized mechanistic pathways underlying this association are complex. Interactive and compensatory mechanisms across developmental time are neglected topics. (3) Progress has been made in multiexposure studies. However, challenges remain and these are shared by clinical, translational and public health sciences. (4) From a mental healthcare perspective, a multidisciplinary and system level approach employing developmentally-sensitive measures and timely treatment of (self-)regulation and coregulation problems in a dyadic caregiver-child and family level approach seems needed. The existing evidence-base is sparse.

SUMMARY

During the perinatal period, addressing vulnerable contexts and building resilient systems may promote neurobehavioral development. A pluralistic approach to research, taking a multidisciplinary approach to theoretical models and empirical investigation needs to be fostered.

Perinatal depression and infant and toddler neurodevelopment: A systematic review and meta-analysis

Many studies have focused on the effect of perinatal depression on neurodevelopment among children and adolescents. However, only a few studies have explored this relationship in infants and toddlers with inconsistent results. We performed a systematic review and meta-analysis to evaluate the association between perinatal depression and infant and toddler neurodevelopment during the first two postnatal years. Twenty-three studies were included in this meta-analysis. Perinatal depression was associated with poorer cognitive (Cohen's d = -0.19, SE= 0.06, 95% CI = -0.30 to -0.08), language (Cohen's d = -0.24, SE = 0.09, 95% CI = -0.40 to -0.07), and motor (Cohen's d = -0.15, SE = 0.05, 95% CI = -0.26 to -0.05) development. Subgroup analyses showed that the types of maternal depression (prenatal depression vs. postnatal depression), the method of measuring maternal depression (rating scale vs. diagnostic interview), and the time interval between assessment of exposure and outcome had an impact on the observed effect about neurodevelopment of infants and toddlers. In addition, the results of our study pointed to a stronger significant association between prenatal depression and cognitive, language, and motor delays in infants and toddlers, whereas the association between postnatal depression and cognitive, language, and motor delays in infants and toddlers was not statistically significant. In conclusion, this study provided convincing evidence that the perinatal window is a sensitive period for offspring neurodevelopment.

Maternal Mental Health in Pregnancy and Its Impact on Children's Cognitive Development at 18 Months, during the COVID-19 Pandemic (CONCEPTION Study)

BACKGROUND

The COVID-19 pandemic has significantly affected the mental health of pregnant persons.

OBJECTIVE

We aimed to evaluate the impact of maternal mental health and antidepressant use on children's cognitive development.

METHODS

We followed a cohort of children born during the COVID-19 pandemic. Maternal mental health was self-reported during pregnancy (Edinburgh Postnatal Depression Scale, General Anxiety Disorder-7, stress levels, and antidepressant use). The child's cognitive development was measured using the third edition of the Ages & Stages Questionnaires® (ASQ-3) at 18 months. Multivariate multinomial logistic regression models were built to assess the association between in utero exposure to maternal mental health and ASQ-3 domains: communication, gross motor, fine motor, problem-solving, and personal-social.

RESULTS

Overall, 472 children were included in our analyses. After adjusting for potential confounders, a need for further assessment in communication (adjusted odds ratio (aOR) 12.2, 95% confidence interval (CI) (1.60;92.4)), and for improvement in gross motricity (aOR 6.33, 95%CI (2.06;19.4)) were associated with in utero anxiety. The need for improvement in fine motricity (aOR 4.11, 95%CI (1.00; 16.90)) was associated with antidepressant exposure. In utero depression was associated with a decrease in the need for improvement in problem solving (aOR 0.48, 95%CI (0.24; 0.98)).

CONCLUSIONS

During the COVID-19 pandemic, maternal mental health appears to be associated with some aspects of children's cognitive development.

Parental burnout, depression and emotional development of the preschoolers

Introduction

Parental burnout is becoming more and more prevalent in the world, mainly incultures with high demands towards parents. Parental burnout is distinctive from depression and might have its unique influence on child development, which isunder current international research. This work contributes to the understanding of parental burnout, maternal depression and child emotional development(specifically emotion comprehension) interrelations. Additionally, we explored whether there are differences in the effects of parental burnout and depressionon boys and girls.

Methods

To analyse the emotional development of the preschoolers, the Russian version of the Test of Emotional Comprehension (TEC) was used. We used the Russian version of the Parental Burnout Inventory (PBI) to analyse the level of PB and the Russian version of Beck depression Inventory (BDI) to assess participants' depression level.

Results

Parental burnout positively correlates with child emotional comprehension skills, specifically understanding of external causes (B = 0.20, CI: 0.03; 0.37) and mental causes of emotions (B = 0.22, CI: 0.05; 0.40). This effect is gender dependent and is significantlyhigher for girls (B = 0.54, CI: 0.09; 0.98). The effect of maternal depression on emotion comprehension skills is also gender dependent: total scores on emotioncomprehension tasks are significantly higher for daughters of mothers with depression (B = 0.59, CI: 0.001; 1.18).

Discussion

Maternal depression and parental burnout might provoke development of extra sensitivity and self-regulation strategies in girls.

Maternal antenatal depression's effects on child developmental delays: Gestational age, postnatal depressive symptoms, and breastfeeding as mediators

BACKGROUND

Maternal antenatal depression experienced around conception or during pregnancy may adversely affect child development. This study explores three potential mechanisms of the effects of antenatal depression on children's developmental delays at 2-3 years: gestational age of the child, continued depressive symptoms postnatally, and interrupted breastfeeding practices.

METHODS

Mothers (N = 2888) of 3450 children, including 2303 singletons and 1147 multiples from the Upstate KIDS cohort provided data. Linked hospital discharge data was combined with mothers' reports to identify women with moderate to severe antenatal depression. Gestational age was extracted from birth certificates. Mothers completed a depression screener at 4 months postpartum, reported about their breastfeeding practices from 4 to 12 months postpartum, and completed a developmental delay screener when children were 24, 30, and 36 months.

RESULTS

In unadjusted path analysis models, mothers with antenatal depression had more postnatal depressive symptoms and breastfed fewer months, which translated into children being more likely to have developmental delays. Gestational age was not a mediator. Effects were similar across girls and boys and singletons and twins, and largely held when adjusting for covariates.

LIMITATIONS

Main limitations were the relatively advantaged sample and reliance on maternal report.

CONCLUSIONS

Maternal antenatal depression may impact child development through continued depressive symptoms in the postpartum period and through reduced breastfeeding duration suggesting additional targets for intervention.

Association between maternal reflective function and preschool children’s cognitive abilities

Children’s cognitive abilities (e.g., working memory) are associated with mental health, adaptive behaviors, and academic achievement, and may be enhanced by parental reflective function (i.e., capacity to reflect on mental states, feelings, thoughts, and intentions in one’s child and oneself). We evaluated associations between maternal reflective function and children’s cognitive abilities alone and while controlling for parent-child attachment and interaction quality, and psychosocial (i.e., maternal depressive symptoms, adverse childhood experiences) and sociodemographic (e.g., socioeconomic status) factors. Our sample, recruited in Canada, was primarily white and included 73 mothers and their 4–5 year old preschool children. Maternal reflective function was measured with the Reflective Functioning Scale applied to the Parent Development Interview and the Parental Reflective Functioning Questionnaire. Multiple regression analyses revealed that maternal reflective function was associated with children’s cognitive abilities. The Parent Development Interview rated child-reflective function was associated with children’s higher verbal comprehension alone and while adjusting for covariates (e.g., parent-child interaction quality, socioeconomic status), and the Parental Reflective Functioning Questionnaire Interest and Curiosity with higher verbal comprehension while adjusting for parent-child interactions and attachment pattern. The Parental Reflective Functioning Questionnaire Certainty in Mental States was associated with higher working memory scores for children while adjusting for covariates. Full Scale IQ and Visual Spatial Index were not significantly associated with maternal reflective function. Associations were found between secure and disorganized attachment with higher verbal comprehension and lower working memory, respectively. These findings highlight the importance of high maternal reflective function to cognitive abilities in early childhood.

A Systematic Review of Longitudinal Studies Investigating the Association Between Early Life Maternal Depression and Offspring ADHD

OBJECTIVE

The systematic review sought to understand the relationship between maternal depression and later ADHD in children.

METHOD

Three databases were used to identify the studies (Medline, Web of Science and PsychInfo) resulting in 1,223 studies being screened and 14 articles being included in the review.

RESULTS

The majority of studies (N = 11) reported a significant relationship between maternal depression (across both prenatal and postnatal periods) and ADHD symptoms in children. This relationship remained significant when temperament, or past ADHD symptoms were controlled for. Several methodological issues were identified including; overreliance on maternal report and parental ADHD not being accounted for in most studies.

CONCLUSION

The review adds to the literature regarding the temporal relationship between maternal depression and the development of ADHD in children, and thus supports the case for improving access to mental health services for mothers as a preventative strategy in the development of child psychopathology.

Theory of Mind in Pre-school Aged Children: Influence of Maternal Depression and Infants' Self-Comforting Behavior

A milestone of child development is theory of mind (ToM): the ability to attribute mental states, especially beliefs and desires, to other persons and to understand that their behavior is guided by mental states. The learning process about the mental world also takes place in social communication and interaction, beginning in infancy. Infancy is assumed to be a sensitive period for the development of social skills through interaction. Due to limited self-regulatory skills, infants depend on sensitive behavior of their caregivers to regulate affective states and physiological arousal, and in turn, mutually regulated affects allow the infant to gradually acquire the capability to self-regulate negative affective states. Effective and adequate affect regulation is an important prerequisite for environmental interaction and thus for the development of socio-emotional skills. The present study investigated the relation of self-regulatory abilities in infancy and later ToM in pre-school aged children of clinically depressed mothers and healthy controls. The sample comprised of N = 55 mother-child dyads, n = 22 diagnosed with postpartum or lifetime depression according to DSM-IV and n = 33 healthy controls. Mother-infant-interaction was videotaped during the Face-to-Face Still-Face paradigm. At 3 and 42 months postpartum mothers were interviewed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to evaluate maternal psychopathological status according to DSM-IV. At the age of M = 4.0 years, children's ToM abilities were assessed using content-false-belief and location-false-belief tasks. The results of this study show that contrary to our hypotheses, maternal depression did not impair the development of children's ToM-abilities per se. Rather, an interaction effect highlights the role of infant's self-comforting behavior during mother-infant interaction in infancy (3 months postpartum) for ToM-development at pre-school age assessed with the Maxi-task; this association was distinct for female in comparison to male children. The results of this longitudinal study shed light on the discussion, how maternal depression influences child development and point in the direction that self-comforting behaviors in infancy can also be seen as a resource.
