Early-Onset Trajectories of Emotional Dysregulation in Autistic Children.

Emotional dysregulation is a common and debilitating problem for autistic children and their families. However, we know little about early-onset patterns of dysregulation, associated risk factors, and child and family outcomes. We aimed to characterize trajectories of emotional dysregulation in an inception cohort of autistic preschoolers. Caregivers reported on the emotional dysregulation of 396 autistic children using the Aberrant Behavior Checklist (ABC) irritability and hyperactivity scales at 6 timepoints from shortly after ASD diagnosis (ages 2-4 years) to pre-adolescence (10-11 years). Covariance pattern mixture modeling was used to characterize the number and shape of latent dysregulation trajectories that best fit underlying data. Child and family correlates were measured at baseline and ages 10-11 years to characterize early risk factors and pre-adolescent profiles associated with distinct latent trajectories. Three distinct trajectory classes best fit the data: persistently self-regulated (18% of sample); moderate and declining (54%), and persistently dysregulated (28%). Children classified in the persistently dysregulated trajectory lived with more depressed caregivers and in families reporting greater relationship problems and lower household incomes compared to lower-risk trajectories. Few associations were found with baseline child characteristics. Persistent dysregulation problems were associated with significantly worse child mental health and functional outcomes during pre-adolescent years. Risk of persistent severe emotional dysregulation may be identifiable at time of early autism diagnosis. Diagnostic assessments should include contextual risk factors and links to evidence-based family supports and interventions.

Social inequalities in child mental health trajectories: a longitudinal study using birth cohort data 12 countries

BackgroundSocial inequalities in child mental health are an important public health concern. Whilst previous studies have examined inequalities at a single time point, very few have used repeated measures outcome data to describe how these inequalities emerge. Our aims were to describe social inequalities in child internalising and externalising problems across multiple countries and to explore how these inequalities change as children age.MethodsWe used longitudinal data from eight birth cohorts containing participants from twelve countries (Australia, Belgium, Denmark, France, Germany, Greece, Italy, Netherlands, Poland, Norway, Spain and the United Kingdom). The number of included children in each cohort ranged from N = 584 (Greece) to N = 73,042 (Norway), with a total sample of N = 149,604. Child socio‐economic circumstances (SEC) were measured using self‐reported maternal education at birth. Child mental health outcomes were internalising and externalising problems measured using either the Strengths and Difficulties Questionnaire or the Child Behavior Checklist. The number of data collection waves in each cohort ranged from two to seven, with the mean child age ranging from two to eighteen years old. We modelled the slope index of inequality (SII) using sex‐stratified multi‐level models.ResultsFor almost all cohorts, at the earliest age of measurement children born into more deprived SECs had higher internalising and externalising scores than children born to less deprived SECs. For example, in Norway at age 2 years, boys born to mothers of lower education had an estimated 0.3 (95% CI 0.3, 0.4) standard deviation higher levels of internalising problems (SII) compared to children born to mothers with high education. The exceptions were for boys in Australia (age 2) and both sexes in Greece (age 6), where we observed minimal social inequalities. In UK, Denmark and Netherlands inequalities decreased as children aged, however for other countries (France, Norway, Australia and Crete) inequalities were heterogeneous depending on child sex and outcome. For all countries except France inequalities remained at the oldest point of measurement.ConclusionsSocial inequalities in internalising and externalising problems were evident across a range of EU countries, with inequalities emerging early and generally persisting throughout childhood.

Centering Diverse Communities within Mindful Parenting Interventions in the U.S.: A Narrative Literature Review

Background: While mindfulness-based interventions targeted toward parents (and families) in the U.S. offer promise for the treatment and prevention of youth psychological disorders, current research has established the underrepresentation of diverse participants in the research literature. The full extent of inequalities in the demographics of participation in parent mindfulness intervention is less understood. Objective: This study aimed to utilize a narrative literature review approach to examine and describe the degree to which research on mindful parenting interventions is inclusive of BIPOC (Black, Indigenous, and People of Color) communities, non-clinical samples (no diagnosed disorder), cultural adaptions, and skills specific to parenting. Methods: An electronic database search of US-based studies was undertaken for empirical studies that primarily focused on parent mindfulness interventions, which reported outcomes related to either parenting behaviors or child mental health outcomes. After a full-text review, the search resulted in 34 articles. A narrative literature review of the 34 studies was conducted to assess the inclusion of BIPOC communities, non-clinical samples, cultural adaptions, and skills specific to parenting. Results: This review found notable gaps in the degree to which mindful parenting research (1) included BIPOC populations in study samples; (2) focused on non-clinical samples; (3) adapted interventions to align with the cultural needs of participants; and (4) included the application of mindfulness to enhancing knowledge, skills, and behaviors specific to parenting. Conclusions: Given these gaps in the parent mindfulness literature, greater research attention is needed on mindful parenting interventions targeted toward BIPOC communities with no clinical diagnoses, interventions optimized by cultural adaptations, and explicit applications to parenting.

Children’s involvement in the development and evaluation of parent-focused mental health interventions: a scoping review protocol

Objective: This review will (i) describe methods used to involve children in the development and/or evaluation of parent-focused interventions to prevent or treat child mental health problems; (ii) summarize the perspectives of children or adults about these methods; (iii) highlight any reported enablers and barriers; and (iv) identify guidance and make recommendations for further research. Introduction: Parent-focused interventions (where children are not primarily involved or are excluded) have been implemented to address various child mental health outcomes. However, it is unclear to what extent, and to what end, children have been involved in developing and evaluating such interventions. Engaging children in formative research activities, with or without their parents, has the potential to improve quality and implementation. Inclusion criteria: Eligible studies will involve children (5–12 years) in the development and/or evaluation of parent-focused interventions aimed at preventing or treating common child mental health problems (eg, anxiety, depression, ADHD, disruptive behavior) delivered in any setting (eg, school, community, home, health facility). Eligible interventions may include one or more psychosocial practice elements targeting behavioral, cognitive, emotional, interpersonal, social, and/or environmental factors implicated in the onset and maintenance of child mental health problems. Methods: Comprehensive searches will be conducted in five electronic databases (PsycINFO, Medline, CINAHL, Embase, and SCOPUS). Gray literature will be sourced using Google as well as through searches of key organization websites and via notifications on social media. Only English language primary studies will be considered. Findings across a range of methodologies will be charted and combined into a narrative synthesis. Details of this rereview project are available: Open Science Framework: https:osf.io/x9376/

Exploring Screen Time and Its Effects on Children's Mental Health: A Cross-Sectional Study.

Background The increasing prevalence of screen-based activities among children has raised concerns about potential mental health effects. This study investigates the relationship between screen time and mental health outcomes in children aged 6 to 14 years in Saudi Arabia and Bahrain, focusing on emotional symptoms, conduct problems, hyperactivity, peer problems, and depressive symptoms. Methods A cross-sectional study was conducted with 670 children recruited through stratified random sampling. Data were collected using self-reported questionnaires and parental surveys from January to June 2024. Screen time was assessed across four activities: TV viewing, smartphone usage, computer/tablet use, and video game playing, recorded separately for weekdays and weekends. Mental health was evaluated using the Strengths and Difficulties Questionnaire (SDQ) and the Children's Depression Inventory (CDI). Descriptive statistics and Pearson correlation coefficients were used to analyze the data. Results Participants reported a mean total screen time of 7.25 ± 2.4 hours on weekdays and 8.4 ± 2.65 hours on weekends. Smartphone usage (2.75 ± 1.3 hours/day) was the most common activity. Emotional symptoms, conduct problems and depressive symptoms were significantly correlated with both weekday and weekend total screen time (weekday r = 0.43, r = 0.31, and r = 0.49, respectively, p < 0.001; weekend r = 0.47, r = 0.33, and r = 0.54, respectively, p < 0.001). Smartphone usage had the strongest association with depressive symptoms (r = 0.46, p < 0.001). Conclusion This study identifies a significant positive correlation between increased screen time and adverse mental health outcomes in children, particularly emotional symptoms and depressive symptoms. The findings emphasize the need for public health strategies to manage screen time and promote healthier digital habits to mitigate the potential negative effects on children's mental health.

The Effect of Screen Time and Positive School Factors in the Pathway to Child and Youth Mental Health Outcomes.

Beyond achievement, educational settings offer informal supports that may be critical for child and youth mental health. However, children's educational environments have experienced significant disruption with the coronavirus pandemic. School settings offer unique opportunities to support children's mental health, but research must identify powerful points of intervention. This study examined school factors (aspirations, perceived competence, sense of belonging, and emotional engagement) as predictors of children's mental health, and the potential consequences of increasing screen time in and outside of school. Participants (N = 707) were parents and their children (6-18 years) from community and clinical settings who completed prospective surveys about children's school experiences and mental health symptoms (November 2020-May 2022). Standardized measures of depression, anxiety, irritability, inattention, and hyperactivity were collected. Structural equation modelling tested longitudinal associations between screen time, school factors, and mental health outcomes. Positive associations between each of the school factors (B = 0.14 [SE = 0.04] to B = 0.43 [SE = 0.04]) suggested they may reinforce one another. Longitudinally, sense of belonging and emotional engagement at school predicted lower severity for symptoms of depression, anxiety, irritability, and inattention (B=-0.14 [SE = 0.07] to B =-0.33 [SE = 0.10]). Greater screen time was associated with lower aspirations and perceived competence (B = - 0.08 [SE = 0.04] to B = - 0.13 [SE = 0.06]). Results suggest that school factors beyond achievement may be key correlates of child and youth mental health. While curriculum expectations emphasize academic achievement, an investment in supporting positive attitudes and aspirations at school is also warranted.

A systematic review examining outcomes of children following permanency placements

Children in care have experienced adversities, including maltreatment prior to contact with the system, negatively impacting on their mental health outcomes. The type of placement and length of time in care are thought to be important and the child welfare system aim is to achieve a permanent decision for children that best supports their needs by establishing a stable familial network. Permanency decisions can include reunification, foster care, kinship care, adoption, and residential placements. This review aims to establish to what extent permanent placement type, maltreatment experienced, length of time in care and age at which permanency is achieved impacts child mental health outcomes. Following PRISMA guidelines, five databases (ASSIA, CINAHL, PsycINFO, Scopus and SocINDEX) and two registers (CENTRAL and TRoPHI) were systematically searched yielding six articles for inclusion in the study. Data were extracted and articles critically appraised utilising the Crowe Critical Appraisal Tool (CCAT). Papers reported mixed findings for permanent placement type and child mental health outcomes with little or no significant overall differences reported. Type of maltreatment experienced moderated the type of mental health symptomology reported. Difficulties in attachment and social relationships were reported for children placed older than two years, although confounding factors such as type of maltreatment likely reduce the strength of the association. Typically, children in permanent placements had better outcomes compared with peers in short-term or unstable placements. A lack of suitable validated and age-appropriate outcome measures and the existence of confounding factors impair our understanding of the interaction between pre-care adversities, the child welfare system itself and permanent placement outcomes.

Unveiling the effects of energy poverty on mental health of children in energy-poor countries

While existing literature extensively investigates the adverse effects of energy poverty on physical health, exploring its impacts on the mental well-being of school-aged children (5–14 years old) remain underexplored, particularly in the energy-deprived regions of South Asia and Sub-Saharan Africa. This research aims to bridge this gap by delving into the indirect pathways through which energy poverty influences the mental health of these children, explicitly examining anxiety and depression, with a particular focus on child abuse as a potential mediating factor. This study employs comprehensive data at both the country level, covering 52 energy-poor nations from 2000 to 2019, and the household level, covering 18 energy-poor nations. This study utilizes a two-step system generalized method of moment approach to unveil the significant relationships between energy poverty and heightened levels of anxiety and depression. Furthermore, the study employs advanced statistical methods to analyze household-level data, including multilevel logistic regression, Probit instrumental regression models, and mediation analysis. These analyses confirm a robust association between energy poverty and an increased likelihood of anxiety and depression among school-aged children. The study also uncovers a concerning link between energy poverty and child abuse, emphasizing its role as a contributing factor to adverse mental health outcomes in children. The findings of this study offer critical insights for policymakers, highlighting the urgent need for targeted interventions and policies aimed at alleviating the adverse mental health effects of energy poverty on children. By addressing this issue, policymakers can contribute to fostering children's overall well-being and development in energy-poor regions.

Protocol of the Nutritional, Psychosocial, and Environmental Determinants of Neurodevelopment and Child Mental Health (COINCIDE) study

Background Over 250 million children are developing sub-optimally due to their exposure to early life adversities. While previous studies have examined the independent effects of nutritional status, psychosocial adversities, and environmental pollutants on children’s outcomes, little is known about their interaction and cumulative effects. Objectives This study aims to investigate the independent, interaction, and cumulative effects of nutritional, psychosocial, and environmental factors on children’s cognitive development and mental health in urban and rural India. It also seeks to explain pathways leading to inequities in child development outcomes at the individual, household, and neighbourhood levels. Methods A mixed-methods prospective cohort study will be conducted on 1600 caregiver-child dyads (child age 3–9 years) in urban and rural India. Nutritional status, psychosocial adversities, environmental pollutants, and child mental health outcomes will be assessed using parent-report questionnaires. Performance-based measures will be used to assess cognitive outcomes. Venous blood and urine samples will be used to measure nutritional and pesticide biomarkers in 500 children. Indoor air pollution will be monitored in 200 households twice, during two seasons. Multilevel regression, weighted quantile sum regression, and Bayesian kernel machine regression will assess the individual and combined effects of exposures on child outcomes. Thematic analysis of in-depth interviews and focus group discussions will explore pathways to early childhood development inequities. Discussion The data will be used to formulate a Theory of Change (ToC) to explain the biological, psychosocial, and environmental origins of children’s cognitive and mental health outcomes across the first decade of life in diverse Indian settings, which will then inform context-specific intervention targets for promoting children’s outcomes beyond the first 1000 days, potentially generalizable to similar under-resourced global settings. The COINCIDE research infrastructure will comprise a valuable global health resource, including prospective cohort data, validated study tools, and stored biological and environmental samples for future studies.

Mental health in Norwegian children and adolescents exposed to childhood maltreatment: a comparison to a general population sample

The current study aimed to compare mental health outcomes of children and adolescents with maltreatment experiences to a general population sample. A secondary aim was to examine sex differences in mental health outcomes, and the association between polyvictimization and mental health. The two samples were age- and sex-matched, and data was collected from caregiver-reports and self-reports. 1378 participants aged 5 to 18 years were included in the study. Children and adolescents exposed to maltreatment had more mental health problems than the general population sample. Large effect sizes (d ≥ 0.8) were found for emotional problems (d = 1.19), hyperactivity problems (d = 0.88), peer problems (d = 0.86), and the impact score (d = 0.93). A moderate to large effect size was found on the conduct problems subscale (d = 0.68), and a small effect size was found on the prosocial subscale (d = −0.22). There was a dose-response relationship between cumulative maltreatment exposure and the severity of mental health problems. Childhood maltreatment was associated with considerably more emotional problems, hyperactivity problems, and peer problems, which in turn can impact the daily life of the exposed children and adolescents. Effective support measures for maltreated young people must be a priority.

Validating a Pragmatic Measure of Evidence-Based Practice (EBP) Delivery: Therapist Reports of EBP Strategy Delivery and Associations with Child Outcome Trajectories.

Pragmatic measures of evidence-based practice (EBP) implementation can support and evaluate implementation efforts. We examined the predictive validity of therapist reports of EBP strategy delivery for children's mental health outcomes. Data were obtained from 1,380 sessions with 248 children delivered by 76 therapists in two county systems. Children (Mage=11.8 years, SD = 3.7) presented with internalizing (52%), externalizing (27%), trauma (16%), and other (5%) concerns. Therapists reported their delivery of EBP strategies on a revised version of the EBP Concordant Care Assessment (ECCA; Brookman-Frazee, et al., Administration and Policy in Mental Health and Mental Health Services Research, 48, 155-170, 2021) that included 25 content (e.g., parenting, cognitive behavioral) and 12 technique strategies (e.g., modeling, practice/role-play). On average, 5.6 ECCA session reports (SD = 2.3) were obtained for each client, and caregivers reported symptoms on the Brief Problem Checklist (Chorpita, et al., Journal of Consulting and Clinical Psychology, 78(4), 526-536, 2010) at baseline, weekly over two months, and again at four months. Multilevel models examined whether the mean extensiveness of each EBP strategy predicted trajectories of child outcomes. More individual technique (6 of 12) than content strategies (1 of 25) were associated with outcome trajectories. For techniques, more extensive use of Performance Feedback and Live Coaching and less extensive use of Addressing Barriers were associated with greater declines in total symptoms, and more extensive use of Establishing/Reviewing Goals, Tracking/Reviewing Progress, and Assigning/Reviewing Homework was associated with declines in externalizing symptoms. For content, more extensive use of Cognitive Restructuring was associated with declines in total symptoms. In addition, higher average extensiveness ratings of the top content strategy across sessions was associated with greater declines in total and externalizing symptoms. Therapist-reported delivery of some EBP strategies showed evidence of predictive validity and may hold utility in indexing quality of care.

The Coronavirus Pandemic and Mental Health Presentations of Young Children.

Children under the age of four are emotionally vulnerable to global disasters, such as the COVID-19 pandemic given the lack of socialization opportunities and coping mechanisms, and susceptibility to heightened caregiver stress. Currently, the extent to which the pandemic impacted the mental health of clinically referred young children is unknown. To evaluate how children's mental health outcomes were impacted during the pandemic, interRAI Early Years assessments (N = 1343) were obtained from 11 agencies across the Province of Ontario, during pre-pandemic and pandemic timepoints. Findings demonstrated that the number of completed assessments declined during the pandemic. Further, children's emotional concerns differed before and during the pandemic, whereby children exhibited greater emotional dysregulation during the pandemic. However, there were no significant differences when examining caregiver distress, parenting strengths, child distractibility/inattention or behavioural issues. Implications for young children and their families, clinicians, and policy makers are discussed.

Maternal Antenatal Depression Is Associated With Metabolic Alterations That Predict Birth Outcomes and Child Neurodevelopment and Mental Health

BackgroundEvidence regarding metabolic alterations associated with maternal antenatal depression (AD) is limited, and their role as potential biomarkers that improve the prediction of AD and adverse childbirth, neurodevelopmental, and mental health outcomes remains unexplored. MethodsIn a cohort of 331 mother-child dyads, we studied associations between AD (a history of medical register diagnoses and/or a Center for Epidemiological Studies Depression Scale score during pregnancy ≥ 20) and 95 metabolic measures analyzed 3 times during pregnancy. We tested whether the AD-related metabolic measures increased variance explained in AD over its risk factors and in childbirth, neurodevelopmental, and mental health outcomes over AD. We replicated the findings in a cohort of 416 mother-child dyads. ResultsElastic net regression identified 15 metabolic measures that collectively explained 25% (p < .0001) of the variance in AD, including amino and fatty acids, glucose, inflammation, and lipids. These metabolic measures increased the variance explained in AD over its risk factors (32.3%, p < .0001 vs. 12.6%, p = .004) and in child gestational age (9.0%, p < .0001 vs. 0.7%, p = .34), birth weight (9.0%, p = .03 vs. 0.7%, p = .33), developmental milestones at the age of 2.3 to 5.7 years (21.0%, p = .002 vs. 11.6%, p < .001), and any mental or behavioral disorder by the age of 13.1 to 16.8 years (25.2%, p = .03 vs. 5.0%, p = .11) over AD, child sex, and age. These findings were replicated in the independent cohort. ConclusionsAD was associated with alterations in 15 metabolic measures, which collectively improved the prediction of AD over its risk factors and birth, neurodevelopmental, and mental health outcomes in children over AD. These metabolic measures may become biomarkers that can be used to identify at-risk mothers and children for personalized interventions.

Is the availability and quality of local early childhood education and care services associated with young children's mental health at school entry?

PurposeThis study investigated the relationship between geographic availability (and quality) of local early childhood education and care services and children's early mental health outcomes for all children entering their first year of full-time school in Melbourne, Australia. MethodsWe capitalise on a unique population linked dataset, the Australian Early Development Census – Built Environment, which combines geospatial measures of children's neighbourhoods with demographic information and child mental health outcomes for all school entrants in Australia's 21 most populous cities and towns. Objective early childhood education and care service location and quality exposures were developed for each study child based on home addresses. Four geographic availability exposures (counts within 3 km) were examined for cross-sectional associations with child mental health outcomes (externalising and internalising difficulties, competence). We estimated associations using multilevel logistic regression (Markov Chain Monte Carlo estimation) adjusting for child demographics and stratifying by urbanicity. ResultsChildren with higher counts of high-quality preschool services within 3 km of home had lower odds of difficulties and higher odds of competence. Overall, exposures were most consistently associated with children's competence. Across all outcomes, the most consistent patterning was observed for children living in the inner city and middle ring. Results varied depending on whether service quality was accounted for in measures of availability. Geographic availability of early childhood services showed patterning by neighbourhood disadvantage and by maternal education. ConclusionWe found some evidence that geographic availability of high-quality preschools was associated with better child mental health outcomes, but results varied by urbanicity. While future research is required to unpack these differences, these findings indicate the importance of accounting for both geographic availability and service quality simultaneously in future research, policy and practice.

Exposure to parental problem drinking during adolescence and symptoms of depression and anxiety in young adulthood: A Swedish national cohort study.

Previous research has shown associations between parental problem drinking and adverse mental health outcomes in children. However, while many studies assess parental alcohol problems based on clinical measures, longitudinal studies that investigate the impact of potentially less severe levels of parental alcohol problems are scarce. The aim of this study was to examine if the existence and severity of child-reported parental problem drinking in adolescence is associated with symptoms of depression and anxiety in young adult men and women. Data was obtained from the Swedish national cohort study Futura01, including 3143 participants born in 2001 who were surveyed in 2017 (age 15-16) and 2022 (age 20-21). Parental problem drinking was measured at age 15-16 with the short version of The Children of Alcoholics Screening Test. Depression and anxiety symptoms were measured at age 20-21 with the Patient Health Questionnaire-4. Registry information on gender, parental education and parental country of birth were included as covariates. The results demonstrated an exposure-response pattern, with greater severity of parental problem drinking associated with an increased probability of reporting depression and anxiety symptoms 5 years later. The association between parental problem drinking and subsequent depression symptoms was however present only in females. Adolescents exposed to parental problem drinking have elevated risks of long-term adverse mental health. These risks increase with greater severity of parental problem drinking. It is thus crucial with efforts preventing parental problem drinking and efforts promoting health among children and adolescents who are exposed.

Particulate Matter Exposure and Default Mode Network Equilibrium During Early Adolescence.

Background: Air pollution exposure has been associated with adverse cognitive and mental health outcomes in children, adolescents, and adults, although youth may be particularly susceptible given ongoing brain development. However, the neurodevelopmental mechanisms underlying the associations among air pollution, cognition, and mental health remain unclear. We examined the impact of particulate matter (PM2.5) on resting-state functional connectivity (rsFC) of the default mode network (DMN) and three key attention networks: dorsal attention, ventral attention, and cingulo-opercular. Methods: Longitudinal changes in rsFC within/between networks were assessed from baseline (9-10 years) to the 2-year follow-up (11-12 years) in 10,072 youth (M ± SD = 9.93 + 0.63 years; 49% female) from the Adolescent Brain Cognitive Development (ABCD®) study. Annual ambient PM2.5 concentrations from the 2016 calendar year were estimated using hybrid ensemble spatiotemporal models. RsFC was estimated using functional neuroimaging. Linear mixed models were used to test associations between PM2.5 and change in rsFC over time while adjusting for relevant covariates (e.g., age, sex, race/ethnicity, parental education, and family income) and other air pollutants (O3, NO2). Results: A PM2.5 × time interaction was significant for within-network rsFC of the DMN such that higher PM2.5 concentrations were associated with a smaller increase in rsFC over time. Further, significant PM2.5 × time interactions were observed for between-network rsFC of the DMN and all three attention networks, with varied directionality. Conclusion: PM2.5 exposure was associated with alterations in the development and equilibrium of the DMN-a network implicated in self-referential processing-and anticorrelated attention networks, which may impact trajectories of cognitive and mental health symptoms across adolescence.

Heterogeneous effects of return migration on children's mental health and cognitive outcomes

As a neglected group, the number of return migrant children is growing with China's monumental volume of labor migration. Using data from 2013 to 2014 China Education Panel Survey, this study examines heterogeneous effects of return migration on children's mental health and cognitive outcomes. Our results show that the effects of return migration on children vary with the propensity for return migration. More importantly, when children are at risk of return migration, even if that risk is small, it already has a negative impact on children's mental health, which reminds us that it needs to take a dynamic view to study the impact of return migration on children. However, the impact of return migration is not all negative, and the findings suggest that return migration can promote the cognitive development of urban-origin migrant children. A striking regional difference emerges from our analysis: due to urban-rural gap, the impact of return migration on children from urban and rural areas is different. Specifically, return migration has a positive effect on the cognitive development of urban-origin migrant children while return migration does some harm to that of rural-origin migrant children, which implies that return migration may widen the gap between urban and rural children.

Aspects of Area Deprivation Index in Relation to Hippocampal Volume Among Children

Area deprivation index (ADI) has been shown to be associated with reduced hippocampal volume (HV) among youths. The social environment may interact with the association between ADI and HV. To investigate which aspects of ADI are uniquely associated with bilateral HV and whether school and family environments have moderating interactions in associations between ADI and HV. This cross-sectional study used data from the Adolescent Brain and Cognitive Development (ABCD) study. Participants aged 9 and 10 years were recruited from 21 sites in the US between September 2016 and August 2018. Data analysis was performed between March 2023 and April 2024. ADI aspects were derived from participant primary home addresses provided by parents or guardians. HV was automatically segmented from structural brain images ascertained from magnetic resonance imaging. Multiple generalized linear mixed modeling tested associations between 9 indices of ADI and bilateral HV, with family groups and recruitment sites as random effects. After stepwise backward selection, models were adjusted for individual-level covariates, including age, sex, race and ethnicity, parental education, household income, and estimated intracranial volume. This study included 10 114 participants aged 9 and 10 years (median [IQR] age, 9.92 [9.33-10.48] years; 5294 male [52.3%]; 200 Asian [2.0%], 1411 Black [14.0%], and 6655 White [65.8%]; 1959 Hispanic [19.4%]). After stepwise backward selection and adjusting for covariates, only the percentage of neighborhood-level single-parent households was associated with right HV (adjusted β per 1-SD increase in single-parent households, -0.03; 95% CI, -0.06 to -0.01; P = .01). School environment interacted with neighborhood-level single-parent households in its association with right HV (adjusted β per 1-SD increase in score, 0.02; 95% CI, 0.01 to 0.03; P = .003), such that there was an inverse association only among those at a school with the mean environment score (adjusted β per 1% increase in single-parent households, -0.03; 95% CI, -0.05 to -0.01; P = .02) and worse (-1 SD score) school environment score (adjusted β per 1% increase in single-parent households, -0.05; 95% CI, -0.09 to -0.01; P < .001) but not among those at better (+1 SD score) school environments. In this study, an increased percentage of neighborhood-level single-parent households was associated with reduced right HV among children in schools with the mean or worse but not better environment score. These findings suggest that longitudinal research concerning the association of neighborhood-level characteristics and school environments with hippocampal development may be warranted to better understand complex interactions between various social factors and child neurodevelopment and mental health outcomes.

From infancy to eight: How early maternal mental health, emotion reminiscing, and language shape children's mental health.

To test the transmission of mental health difficulties from mother to child, we examined mediation through emotion reminiscing conversations and child language. Maternal depression symptoms were measured at 9 months post-partum, and child mental health outcomes were measured at age 8 years. Emotion reminiscing conversations between 1,234 mother-child pairs (624 boys, 610 girls) were recorded as part of a large, diverse, longitudinal cohort Growing Up in New Zealand. The 1,234 reminiscing conversations were transcribed and coded for maternal elaboration and emotion resolution quality (mother and child). The coded reminiscing variables did not mediate the pathway from maternal depression to child mental health outcomes; however, each maternal reminiscing variable together with child language skill serially mediated the relationship from maternal depression symptoms to child-reported anxiety and depression symptoms, and parent-reported child externalizing symptoms. Language as a skill and it's use as a tool for making shared meaning from past events are highlighted as possible mechanisms for the intergenerational transmission of mental health difficulties. These findings point to potential opportunities for early interventions, including prevention of and support for postnatal depression, family intervention in reminiscing training, and supporting child language development.

Swimming in children: benefits for early aquatic development

Swimming offers various benefits for children's development, including physical, cognitive, and psychosocial aspects. The present study aim to known the benefits the Swimming in children for development for early aquatic. A systematic review of bibliographic analysis was carried out through analytical tracking techniques and documentary quantification from various search engines: Google Scholar, Dialnet, Redalyc, Scielo, where a total of 223 documents were obtained, selecting the sample of this, then continued with the following coding: 1) Title of the article; 2) Name of the authors and year; 3) Objective; 4) Sample- Instruments; 5) Results. This finding supports the notion that exposure to blue spaces, such as oceans, lakes, or swimming pools, can have a positive influence on mental health outcomes in children. Incorporating aquatic activities into a comprehensive approach to child development may provide additional opportunities for promoting positive mental health outcomes. The findings support the efficacy of swimming and water activities in promoting physical, psychological, and psychomotor development in children.
