Maternal Depressive Symptoms and Developmental Delay at Age 2: A Diverse Population-Based Longitudinal Study

Accurate identification of genes associated with brain disorders by integrating heterogeneous genomic data into a Bayesian framework

BACKGROUND

Genome-wide association studies (GWAS) have revealed many brain disorder-associated SNPs residing in the noncoding genome, rendering it a challenge to decipher the underlying pathogenic mechanisms.

METHODS

Here, we present an unsupervised Bayesian framework to identify disease-associated genes by integrating risk SNPs with long-range chromatin interactions (iGOAT), including SNP-SNP interactions extracted from ∼500,000 patients and controls from the UK Biobank, and enhancer-promoter interactions derived from multiple brain cell types at different developmental stages.

FINDINGS

The application of iGOAT to three psychiatric disorders and three neurodegenerative/neurological diseases predicted sets of high-risk (HRGs) and low-risk (LRGs) genes for each disorder. The HRGs were enriched in drug targets, and exhibited higher expression during prenatal brain developmental stages than postnatal stages, indicating their potential to affect brain development at an early stage. The HRGs associated with Alzheimer's disease were found to share genetic architecture with schizophrenia, bipolar disorder and major depressive disorder according to gene co-expression module analysis and rare variants analysis. Comparisons of this method to the eQTL-based method, the TWAS-based method, and the gene-level GWAS method indicated that the genes identified by our method are more enriched in known brain disorder-related genes, and exhibited higher precision. Finally, the method predicted 205 risk genes not previously reported to be associated with any brain disorder, of which one top-risk gene, MLH1, was experimentally validated as being schizophrenia-associated.

INTERPRETATION

iGOAT can successfully leverage epigenomic data, phenotype-genotype associations, and protein-protein interactions to advance our understanding of brain disorders, thereby facilitating the development of new therapeutic approaches.

Systematic Review of Barriers to and Facilitators of Screening for Postpartum Depression at Well-Child Visits in the United States

OBJECTIVE

To identify and evaluate barriers to and facilitators of screening for postpartum depression (PPD) during well-child visits in the United States. Additionally, to describe prior work on PPD screening tool evaluation and outcomes from PPD screenings conducted within the well-child setting.

DATA SOURCES

A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Five databases (Pub Med, PsycINFO, Web of Science, CINAHL, and Cochrane Library) were searched.

STUDY SELECTION

Randomized controlled trials, case studies, cross-sectional studies, case-control studies, cohort studies, qualitative studies, and quasi-experimental studies conducted in the United States were included. The Standard Quality Assessment Criteria Tool (QualSyst) was used to assess the methodologic quality of each included study.

DATA EXTRACTION

Sample, setting, methods, screening tools used, location of study setting, intervention, and salient findings were extracted and summarized for further analysis and synthesis.

DATA SYNTHESIS

Quantitative studies were rated on 14 aspects, and qualitative studies were rated on 10 aspects, per QualSyst. Studies received a score of 2, 1, 0, or not applicable based on scoring criteria, with higher scores indicating greater methodologic quality.

CONCLUSION

We found that barriers to PPD screening included concerns regarding time for screening, adequate training, and limited ability for referral. Facilitators of PPD screening included electronic prompts for providers, as well as tool availability and familiarity. Our results indicate that education and training about PPD screening in the pediatric setting are important next steps in addressing the rising concern of PPD in the United States.

The Association Between Maternal Depressive Symptoms and Toddlers' Developmental and Behavioral Problems: A Population-Based Study

This study aims to compare the developmental-behavioral profiles of 2-year-olds of mothers who experienced postpartum and/or current depression with profiles of toddlers of mothers without depression at either time using population-based Rhode Island data. Weighted data from Rhode Island Department of Health's Pregnancy Risk Assessment Monitoring System and Rhode Island's follow-up Toddlers Wellness Overview Survey distributed to mothers giving birth between 2006 and 2008 were analyzed. Compared with non-depressed mothers, those with any depression following childbirth reported more concerns with their toddlers' receptive language, social-emotional development, and their sleep and feeding behaviors. When adjusted for demographics, persistent depression remained associated with social-emotional (adjusted odds ratio [aOR] = 7.53, 2.78-20.34) and feeding concerns (aOR = 3.13, 1.36-7.22), and current depression was associated with social-emotional concerns (aOR = 2.52, 1.26-5.01). We conclude that pediatric providers should explore maternal mental health as a mediating and potentially modifiable factor beyond the postpartum period when toddlers present with developmental-behavioral challenges.

Exploring the validity of the ASQ-SE for socio-emotional competency screening of a low-risk Asian cohort at 2 years of age

AIMS

To assess the Ages & Stages Questionnaire: Social-Emotional (ASQ-SE)'s concurrent validity in a low-risk Singapore cohort and study its association with maternal mental health status.

METHODS

Concurrent validity of the parent-filled ASQ-SE with Child Behavior Checklist (CBCL1.5-5) was evaluated in 341 children at age 24 months. Data on maternal anxiety and depression were collected using the State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory-Second Version (BDI-II). ASQ-SE cut-off scores based on receiver operating characteristic curve were compared to CBCL scores to derive a local ASQ-SE "at risk" cut-off score. Correlations of ASQ-SE with CBCL scores and with maternal STAI and BDI scores were evaluated using Pearson coefficients.

RESULTS

Using a cut-off score of 51 at 24 months, ASQ-SE had acceptable concurrent validity, with an AUC of 0.819(0.765-0.872), 70 % sensitivity and 79 % specificity. Mothers of children with "at-risk" ASQ-SE scores had significantly higher STAI and BDI-II scores. ASQ-SE had moderate- high correlations (r = 0.32-0.53) (p < .01) with CBCL scores at 24 and 48 months and with maternal mental health status(r = 0.32).

INTERPRETATION

ASQ-SE can be a useful tool for screening child's socio-emotional competence for primary health care use in Singapore Dyadic mental health screening would be helpful in identifying families at risk.

Pediatrician and parental evaluation of child neurodevelopment at 2 years of age

BACKGROUND

The early identification of infants with a risk for neurodevelopmental disorders in the first few years of life is essential for better developmental outcomes. Screenings should be carried out by combining the family pediatricians' and parents' perspectives, the two fundamental sources of information on children's health. The present study has three aims: (a) to test the feasibility of parent-report instruments to detect warning signs in their children's development; (b) to ascertain whether there is an agreement between the family pediatricians' (FP) clinical judgments of warning signs and the parental perceptions; (c) to determine whether there is a link between parents' distress and child development.

METHODS

Within the NASCITA birth cohort, in addition to the family pediatrician's clinical evaluation with routine tools, the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) was completed by parents to assess the child's language, social skills, behavior, and sensory areas. Parents were also asked to complete the Parenting Stress Index, Short Form (PSI-SF) to verify the magnitude of stress in the parent-child system. Univariate and multivariate analyses were performed to evaluate the association between child and parental characteristics and the presence of warning signs.

RESULTS

The follow-up assessment was completed for 435 infants: 69 (15.8%) presented warning signs: 43 in the pediatrician's assessment and 36 in the M-CHAT-R (10 in both). A total of 16 children (14 with warning signs) received a diagnosis after a specialist evaluation. Being male (OR 2.46, 95%CI: 1.23-4.91) and having sleep disorders (OR 2.43, 95% CI 1.17-5.04) was associated with a greater likelihood of warning signs in the multivariate analysis, while reading aloud was a protective factor (not exposed versus exposed (OR = 3.14; 95% CI 1.60-6.17). For 73 children (18.4%), at least one parent tested positive for PSI-SF. An increased prevalence of parental distress was observed in children with warning signs (OR 2.36, 95% CI 1.27-4.37).

CONCLUSIONS

Integrating physician and parental perspectives during well-child visits and in clinical practice appears feasible and can improve the identification of children at risk of developmental disorders.

Association between maternal psychological distress and children's neurodevelopment in offspring aged 4 years in Japan: The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study

AIM

An association between maternal psychological distress and children's development has been reported, but  reports from Japan are limited. This study aimed to examine the association of maternal psychological distress with children's neurodevelopment in Japan.

METHODS

The study assessed data of 7646 mother-infant pairs in the Japanese population. We used Kessler Psychological Distress Scale, a screening tool for psychological distress, to assess maternal psychological distress in early pregnancy and 2 years postpartum and divided it into four categories: none in both the pre-natal and post-natal periods, only the pre-natal period, only the post-natal period and both the pre-natal and post-natal periods. Children's neurodevelopment was assessed using the Ages & Stages Questionnaires Third Edition (ASQ-3) at 4 years of age. ASQ-3 comprises five domains (communication, gross motor, fine motor, problem solving and personal-social), and the score of less than -2 standard deviation relative to the mean in reference was defined as having developmental delay. We conducted multivariate logistic regression analysis to examine the association between maternal psychological distress and children's neurodevelopment.

RESULTS

The prevalence of developmental delay of communication, gross motor, fine motor, problem solving and personal-social were 4.0%, 4.3%, 4.9%, 3.8% and 4.6%, respectively. Maternal psychological distress in only the postpartum period and both pre-natal and postpartum periods were associated with risks of developmental delay in all domains. Maternal psychological distress in only the pre-natal period was associated with developmental delay in communication.

CONCLUSIONS

Maternal psychological distress is associated with risks of children's developmental delay.

Prenatal depression exposure alters white matter integrity and neurodevelopment in early childhood

Prenatal exposure to maternal depression increases the risk for onset of emotional and behavioral disorders in children. We investigated the effects of exposure to prenatal depression on white matter microstructural integrity at birth and at 2-3 years, and associated neurodevelopment. Diffusion-weighted images were acquired for children of the Drakenstein Child Health Study at 2-4 weeks postpartum (n=70, 47% boys) and at 2-3 years of age (n=60, 58% boys). Tract-Based Spatial Statistics was used to compare, using an ROI based approach, diffusion tensor metrics across groups defined by presence (>19 on Beck's Depression Inventory and/or >12 on the Edinburgh Postnatal Depression Scale) or absence (below depression thresholds) of depression, and associations with neurodevelopmental measures at age 2-3 years were determined. We did not detect group differences in white matter integrity at neonatal age, but at 2-3 years, children in the exposed group demonstrated higher fractional anisotropy, and lower mean and radial diffusivity in association tracts compared to controls. This was notable in the sagittal stratum (radial diffusivity: p<0.01). Altered white matter integrity metrics were also observed in projection tracts, including the corona radiata, which associated with cognitive and motor outcomes in exposed 2-3-year-olds (p<0.05). Our findings of widespread white matter alterations in 2-3-year-old children with prenatal exposure to depression are consistent with previous findings, as well as with neuroimaging findings in adults with major depression. Further, we identified novel associations of altered white matter integrity with cognitive development in depression-exposed children, suggesting that these neuroimaging findings may have early functional impact.

Risk and protective factors to early childhood development during the COVID-19 pandemic

ABSTRACT Objective: To analyze the risk and protective factors to the development of children under three years of age during the COVID-19 pandemic. Method: Cross-sectional, quantitative study carried out in three early childhood education centers in the city of São Paulo, Brazil, in October 2020. The data were collected with an online questionnaire. Risk and protection factors were measured with the Primeira Infância Para Adultos Saudáveis (Early Childhood For Healthy Adults) instrument and the children's development status was measured using the Caregiver Reported Early Development Instruments – CREDI. Results: The study included 108 parents and guardians of children up to three years of age. Living with grandparents and participating in cash transfer programs were protective factors for child development. The family being headed by a woman posed a significant risk factor for child development. Conclusion: Intersectoral actions to support families headed by women and access to cash transfer programs are essential for promoting equity opportunities for the development in early childhood.

Examining the association between subjective childbirth experience and maternal mental health at six months postpartum

PROBLEM

Childbirth experience can have long-lasting effects on maternal wellbeing.

BACKGROUND

Positive childbirth experiences may strengthen maternal self-confidence, in contrast, negativeexperiences may promote a sense of failure or distrust.

AIM

To examine the contribution of maternal hospital childbirth experience on mental health at 6 months postpartum in a community-based, Chilean sample. An additional aim is to examine which childbirth-related aspects contribute to the global birth experience.

METHODS

One hundred and forty-eight women completed self-report measures of mental health during the third trimester of pregnancy and 3 and 6 months postpartum. At 3months after childbirth, subjective childbirth experience was assessed. Logistic regression analysis examined the contribution of childbirth experience to maternal mental health.

FINDINGS

Negative subjective experience of childbirth contributes to maternal depression and anxiety up to 6 months after childbirth, controlling for mental health during pregnancy and at 3 months postpartum. Quality of care from health professionals made the largest, statistically significant contribution to the global perception of childbirth.

DISCUSSION AND CONCLUSIONS

Subjective experience of childbirth is a modifiable risk factor for the development of postpartum maternal depression and anxiety. Health providers in direct contact with childbearing women may promote maternal emotional wellbeing through sensitive and respectful care.
