Developmental trajectories of body mass index in early childhood : an 8-year longitudinal study

Trajectoires développementales de l’IMC durant l’enfance: Une étude longitudinale sur 8 ans. Introduction : L’obésité infantile, origine de nombreux problèmes de santé, représente un grand défi en santé publique. Récemment, l’importance d’étudier l’évolution du surpoids durant l’enfance ainsi que les facteurs de risques précoces pour l’obésité a été reconnue. Les trajectoires développementales d’indice de masse corporelle (IMC) chez les jeunes représentent une approche innovatrice qui nous permet de mieux comprendre cette problématique importante. Objectifs: 1) Identifier des trajectoires développementales distinctes de groupes d’enfants selon leur IMC durant l’enfance, et 2) Explorer les facteurs de risques précoces qui prédisent l’appartenance de l’enfant à la trajectoire d’IMC le plus élevé Hypothèses: 1) On s’attend à retrouver un groupe d’enfants qui suit une trajectoire d’IMC élevée durant l’enfance. 2) On s’attend à ce que certaines caractéristiques de la mère (ex : tabac pendant la grossesse et IMC élevé), soient associées à l’appartenance de l’enfant au groupe ayant la trajectoire «IMC élevé ». Méthodes: Estimation des trajectoires développementales d’IMC d’enfants, dans un échantillon populationnel (n=1957) au Québec (ELDEQ). Les IMC ont été calculés à partir de données fournies par les mères des enfants et recueillis chaque année sur une durée de 8 ans. Des données propres à l’enfant sa mère, ainsi que socioéconomiques, ont étés recueillies. Une régression logistique multinomiale a été utilisée pour distinguer les enfants avec un IMC élevé des autres enfants, selon les facteurs de risques précoces. Les programmes PROC TRAJ (extension de SAS), SPSS (version 16), et SAS (version 9.1.3) ont été utilisés pour ces analyses. Résultats: Trois trajectoires d’IMC ont étés identifiées : IMC « bas-stable » (54,5%), IMC « modéré » (41,0%) et IMC « élevé et en hausse » (4,5%). Le groupe « élevé et en hausse » incluait des enfants pour qui l’IMC à 8 ans dépassait la valeur limite pour l’obésité. Les analyses de régression logistique ont révélé que deux facteurs de risques maternels étaient significativement associés avec la trajectoire “en hausse” par rapport aux deux autres groupes : le tabac durant la grossesse et le surpoids maternel. Conclusions: Des risques d’obésité infantile peuvent êtres identifiés dès la grossesse. Des études d’intervention sont requises pour identifier la possibilité de réduire le risque d’obésité chez l’enfant en ciblant le tabac et le surpoids maternelle durant la grossesse. Mots clés: Indice de masse corporelle (IMC), obésité infantile, trajectoires développementales de groupe, facteurs de risque précoce, étude populationnelle, tabac pendant la grossesse, obésité maternelle.

The ISSA Pedagogical Standards: a tool to influence quality in early childhood programs

The ISSA Pedagogical Standards were first published in 2001 as a network-developed tool that defined quality in teaching practices and the classroom environment and captured the changes that had occurred in the region since 1994 when the Step by Step Program, an initiative to promote democratic principles in early childhood development and education, was launched. The Program was built on belief that each child has the right to receive maximum support for the development of his or her full potential, and this work should be done in partnership and close cooperation with families, communities and professionals

Empowerment in early childhood intervention : perspectives of parents of children with disabilities

There have been various changes to the manner in which early intervention services for children with disabilities have been provided in recent decades. One of the most significant paradigm shifts that has accoured pertains to a change in the level of family involvement in early intervention, so that families are now required to be equal partners with professionals in the service provision process. It is now policy in Victoria that early intervention services follow a family-centred model of practice. Services adopting this model aim to empower parents, so that they may have impact on their lives, and the lives of their family members, both during and beyond the years of direct service participation. Much of what is known about empowerment to date is based on theory, author opinion, and research that is largely survey-based. There has been little interview-based research, particulary involving parents of children with disabilities, as well as little Australian research conducted regarding empowerment. To the researcher's knowledge, there has been no interview-based research that specifically asked parents of children with disabilities about their perspectives on empowerment and disempowerment. Parents of children with disabilities are not invited to contribute their opinions in services and research. Empowerment is an individual concept and this research provided parents with an opportunity to express their views on this topic. Parent's perspectives on empowerment are vital for service providers who aim to follow the intervention model required by policy. This research, which was guided by the principles of ecological theory and critical theory, involved to individual semi-structured interviews with 37 Victorian families of children with disabilities. Twenty-one of these families had children currently participating in early intervention services, and 16 families had children of mid-primary school age, who had previously participated in early intervention experiences; the factors that they believe influence empowerment and disempowerment; and helpful and unhelpful experiences with early intervention staff and other people in their lives. Data were analysed primarily inductively, in the context of grounded theory. Responses from the two groups of parents were then compared, as were different emergent themes according to helpfulness and empowerment. The nature of enduring empowerment, one of the key objectives of early childhood intervention, was also considered. From the analysis of data, several themes emerged as influential in the empowerment process for both groups of parents including: information, education and knowledge; meeting and talking with other families of children with disabilities; decision-making and choice; having confidence; participation, involvement and input; meeting or addressing families' practical needs; and having a child with a disability. The results of this research provide valuable information for parents, professionals, agencies, organisations, and the wider community, regarding how families can be supported more effectively and how power can be more equitably balanced.

State of play in early childhood teacher training in Victoria

The study explores the varying changes in emphasis on play within early childhood teacher training. Differing interpretations as to the importance of play are identified as well as the factors impacting on the future of a play-based curriculum.

Music, in early childhood education : teachers' levels of confidence and happiness

This paper presents the results of a study which investigates early childhood teachers’ levels of confi dence
and happiness in conducting music activities with young children. A sample of 284 in-service and preservice
early childhood teachers in Hong Kong participated in the study. Two new research instruments
entitled Teachers Music Confi dence Scale (TMCS) and Teachers Happiness Scale (THS) were designed for
data collection to answer the research questions. Results showed that early childhood teachers have the
highest and the lowest level of confi dence in singing and composing/improvising respectively. In-service
teachers showed higher confi dence and happiness levels in conducting several musical activities with
young children than pre-service teachers. There was also a statistically signifi cant relationship between
these two variables. Implications for engagement in music are discussed in the paper.

Supporting ICT based pedagogies in science in rural school settings

Recent research has demonstrated a significant disadvantage for rural teachers in a variety of aspects of ICT use. This context provides a backdrop for two professional learning programs designed to support ICT-based pedagogies in teaching science in Victorian rural primary and secondary schools. In both programs the school-based workshops initiated a community of learners supported with online web-presence. One program used an intensive five-day workshop focused on developing teachers’ knowledge, pedagogical expertise and leadership skills in embedding ICT into classroom practice. The second program provided a one-day workshop focused on integrating ICT skills in teaching science. Factors that affected the uptake of ICT included the considerable diversity in ICT availability and use, teacher competence, lack of support in schools, and online support. To redress rural disadvantage in ICT use, school commitment and focused leadership were identified as central to programs that supported and developed teacher skills and pedagogies over time.

Identification and genetic determination of an early life risk disposition for depressive disorder : atypical stress-related behaviour in early childhood

Progress in psychiatric genetics has been slow despite evidence of high heritability for most mental disorders. We argue that greater use of early detectable intermediate traits (endophenotypes) with the highest likely aetiological significance to depression, rather than complex clinical phenotypes, would be advantageous. Longitudinal data from the Western Australian Pregnancy Cohort (Raine) Study were used to identify an early life behavioural endophenotype for atypical hypothalamic-pituitaryadrenocortical function in adolescence, a neurobiological indicator of anxiety and depression. A set of descriptors representing rigid and reactive behaviour at age 1 year discriminated those in the top 20% of the free salivary cortisol exposure at age 17 years. Genetic association analysis revealed a male-sensitive effect to variation in three specific single nucleotide polymorphisms within selected genes underpinning the overall stress response. Furthermore, support for a polygenic effect on stress-related behaviour in childhood is presented.

Partnerships in early childhood education and care : empowering parents or empowering practitioners

Research acknowledges that outcomes for young children are enhanced when effective partnerships are developed between educators and families. The Australian Early Years Learning Framework provides direction for the professional practice of early childhood educators by acknowledging the importance of educators working in partnership with families. In the Victorian state-based early years framework, family-centred practice has been included as the practice model. Family-centred practice has as its core a philosophy of professionals supporting the empowerment of parents as active decision makers for their child. The early childhood education and care sector in Australia, however, is made up of a workforce which is largely perceived as being undervalued as a profession. This raises questions as to the capacity of these educators to support the empowerment of parents when they themselves are coming from a position of disempowerment due to their professional status. This article reports on findings from a small-scale study of childhood educators working in a long day-care setting which aimed to identify perceptions of the partnerships that exist between themselves and parents. In the course of the investigation, it became evident that some of educators felt disempowered in the relationships that exist with some families.
