Childhood mental and developmental disorders

Childhood mental and developmental disordersencompass neurodevelopmental, emotional, and behavioraldisorders that have broad and serious adverseimpacts on psychological and social well-being. Childrenwith these disorders require significant additional supportfrom families and educational systems; the disordersfrequently persist into adulthood (Nevo and Manassis2009; Polanczyk and Rohde 2007; Shaw and others 2012).These children are more likely to experience a compromiseddevelopmental trajectory, with increased need formedical and disability services, as well as increased riskof contact with law enforcement agencies (Fergusson,Horwood, and Lynskey 1993).

Comparison of performance on process- and product-oriented assessments of fundamental motor skills across childhood

Process-oriented motor competence (MC) assessments evaluate how a movement is performed. Product-oriented assessments evaluate the outcome of a movement. Determining the concurrent validity of process and product assessments is important to address the predictive utility of motor competence for health. The current study aimed to: (1) compare process and product assessments of the standing long jump, hop and throw across age groups and (2) determine the capacity of process assessments to classify levels of MC. Participants included 170 children classified into three age groups: 4–5, 7–8 and 10–11 years old. Participants’ skills were examined concurrently using three process assessments ((Test of Gross Motor Development-2nd edition [TGMD-2]), Get Skilled; Get Active, and developmental sequences) and one product measure (throw speed, jump and hop distance). Results indicate moderate to strong correlations between (1) process assessments across skills and age groups (r range = .37–70) and (2) process and product assessments across skills and age groups (r range = .26–.88). In general, sensitivity to detect advanced skill level is lowest for TGMD-2 and highest for developmental sequences for all three skills. The use of process and product assessments is suggested to comprehensively capture levels of MC in human movement.

Cord blood monocyte-derived inflammatory cytokines suppress IL-2 and induce nonclassic "T(H)2-type" immunity associated with development of food allergy

Food allergy is a major health burden in early childhood. Infants who develop food allergy display a proinflammatory immune profile in cord blood, but how this is related to interleukin-4 (IL-4)/T helper 2 (T(H)2)-type immunity characteristic of allergy is unknown. In a general population-derived birth cohort, we found that in infants who developed food allergy, cord blood displayed a higher monocyte to CD4(+) T cell ratio and a lower proportion of natural regulatory T cell (nT(reg)) in relation to duration of labor. CD14(+) monocytes of food-allergic infants secreted higher amounts of inflammatory cytokines (IL-1β, IL-6, and tumor necrosis factor-α) in response to lipopolysaccharide. In the presence of the mucosal cytokine transforming growth factor-β, these inflammatory cytokines suppressed IL-2 expression by CD4(+) T cells. In the absence of IL-2, inflammatory cytokines decreased the number of activated nT(reg) and diverted the differentiation of both nT(reg) and naïve CD4(+) T cells toward an IL-4-expressing nonclassical TH2 phenotype. These findings provide a mechanistic explanation for susceptibility to food allergy in infants and suggest anti-inflammatory approaches to its prevention.

Reading the map: locating and navigating the academic skills development of pre-service teachers

This article reports on an action research project that was implemented to strengthen preservice teachers’ academic skills and competencies in a Bachelor of Early Childhood Education course. Strategies identified aseffective included mapping assessment tasks to State and National Early Childhood Education Curriculum and Standards Frameworks and Graduate Teacher Standards and against the skills needed to completeassessment tasks. Tools and resources were developed by lecturers to identify students’ existing skill levels and then scaffold the required competencies into course teaching. The critical reflections of lecturers on their professional learning through this process were found to be integral to successful outcomes for students.

Immune biomarkers in the spectrum of childhood noncommunicable diseases

A biomarker is an accurately and reproducibly quantifiable biological characteristic that provides an objective measure of health status or disease. Benefits of biomarkers include identification of therapeutic targets, monitoring of clinical interventions, and development of personalized (or precision) medicine. Challenges to the use of biomarkers include optimizing sample collection, processing and storage, validation, and often the need for sophisticated laboratory and bioinformatics approaches. Biomarkers offer better understanding of disease processes and should benefit the early detection, treatment, and management of multiple noncommunicable diseases (NCDs). This review will consider the utility of biomarkers in patients with allergic and other immune-mediated diseases in childhood. Typically, biomarkers are used currently to provide mechanistic insight or an objective measure of disease severity, with their future role in risk stratification/disease prediction speculative at best. There are many lessons to be learned from the biomarker strategies used for cancer in which biomarkers are in routine clinical use and industry-wide standardized approaches have been developed. Biomarker discovery and validation in children with disease lag behind those in adults; given the early onset and therefore potential lifelong effect of many NCDs, there should be more studies incorporating cohorts of children. Many pediatric biomarkers are at the discovery stage, with a long path to evaluation and clinical implementation. The ultimate challenge will be optimization of prevention strategies that can be implemented in children identified as being at risk of an NCD through the use of biomarkers.

Parent-related mechanisms underlying the social gradient of childhood overweight and obesity: a systematic review

BACKGROUND: Low socio-economic status (SES) is a significant risk factor for childhood overweight and obesity (COWOB) in high-income countries. Parents to young children buffer and accentuate social and cultural influences, and are central to the development of this disease. An understanding of the parent-related mechanisms that underlie the SES-COWOB relationship is needed to improve the efficacy of prevention and intervention efforts. OBJECTIVE: A systematic review of relevant literature was conducted to investigate the mechanisms by which levels of SES (low, middle and high) are associated to COWOB, by exploring mediation and interaction effects. METHOD: Six electronic databases were searched yielding 5155 initial records, once duplicates were removed. Studies were included if they investigated COWOB, SES, parent-related factors and the multivariate relationship between these factors. Thirty studies were included. Factors found to be mediating the SES-COWOB relationship or interacting with SES to influence COWOB were categorized according to an ecological systems framework, at child, parent, household and social system level factors. RESULTS: High parent body mass index, ethnicity, child-care attendance, high TV time (mother and child), breastfeeding (early weaning), food intake behaviours and birthweight potentially mediate the relationship between SES and COWOB. Different risk factors for COWOB in different SES groups were found. For low SES families, parental obesity and maternal depressive symptoms were strong risk factors for COWOB, whereas long maternal working hours and a permissive parenting style were risk factors for higher SES families. None of the studies investigated parental psychological attributes such as attitudes, beliefs, self-esteem and so on as potential mechanisms/risk factors. CONCLUSIONS: Families from different SES groups have different risk and protective factors for COWOB. Prevention and intervention efforts may have improved efficacy if they are tailored to address specific risk factors within SES.

Mathematically rich interactions in early childhood

A large pile of Lego sits on the table, and you watch as young children are actively engaged in creating vehicles. Moments of quick chatter are followed by a quick run around the room to test their latest vehicle, then intense concentration as they try to find the next perfect piece.

Belonging as a force of agency : an exploration of immigrant children’s everyday life in early childhood settings

The notion of agency is being used with increasing frequency in early childhood policies, replacing traditional assumptions about young children’s immaturity and their role as mere recipients of adults’ arrangements. Agency is thus both an educational aspiration as well as a signifier of a strong rights-based political commitment to countering views of children as immature and incompetent. This article develops the argument that agency is inherently a sociocultural product that is driven by children’s clear attempts to bond with others and to develop a sense of belonging. Using examples of the everyday experiences of two Chinese immigrant children in an early childhood centre, the article considers ways in which agency was exercised by the children in an unfamiliar sociocultural setting because they wanted to belong. Some crucial issues are highlighted for practice and policy development in the area of immigrant children’s education, arguing that the shaping of early childhood education requires an attention to children’s ‘invisible’ capabilities, needs to belong and ‘small’ everyday life realities.

Early childhood education and care educators supporting parent-child relationships: a systematic literature review

Building strong relationships between children and parents is vital for children’s social and emotional development. A majority of children attend early childhood education and care (ECEC) settings where they experience a range of relationships (educator–child, educator– parent, parent–child). Educators build relationships with children and parents, yet their influence on parent–child relationships is not well understood. Therefore, an evaluation of interventions/programs designed to promote parent–child relationships in ECEC settings (long day care, occasional care and preschool) and a range of settings (play groups, community groups and health centers) was conducted. The search revealed 21 peer-reviewed studies and seven interventions: two conducted in ECEC settings and five in a range of parent–child support settings. All studies reported intervention efficacy, yet none examined educators’ influence on parent–child relationships. Investigation into current educator practices is recommended to ensure educators are supported to promote and nurture parent– child relationships, consequently strengthening children’s social and emotional development.

Teacher professional learning in early childhood education: insights from a mentoring program

In Australia, as is the case in other countries around the world, the Early Childhood workforce is in the process of ‘skilling up’ to meet government demands related to quality service provision. This paper sets out to identify what constitutes effective teacher professional learning through mentoring. Guided by critical realism and social practice as theoretical perspectives, the paper uses data drawn from the State-wide Professional Mentoring Program for Early Childhood Teachers (2011–2014), Victoria, Australia. The findings identify four C’s essential to effective professional learning – Context: the association between individual aspirations and systemic requirements; Collegiality: the positioning and importance of collegial relationships; Criticality: critical deliberation in ‘safe’ learning environments; and Change: recognition that teacher learning takes place in the domains of professional dispositions, pedagogical knowledge and social capital. These findings point to the need to consider teachers’ contexts of practice in the design of professional development programs such as mentoring, and to conceptualise learning as a socially situated practice rather than a detached pedagogic event.
