Vitamin D-fortified milk achieves the targeted serum 25-hydroxyvitamin D concentration without affecting that of parathyroid hormone in New Zealand toddlers

For young children, the level of vitamin D required to ensure that most achieve targeted serum 25-hydroxyvitamin D [25(OH)D] ≥50 nmol/L has not been studied. We aimed to investigate the effect of vitamin D-fortified milk on serum 25(OH)D and parathyroid hormone (PTH) concentrations and to examine the dose–response relationship between vitamin D intake from study milks and serum 25(OH)D concentrations in healthy toddlers aged 12–20 mo living in Dunedin, New Zealand (latitude 46°S). Data from a 20-wk, partially blinded, randomized trial that investigated the effect of providing red meat or fortified toddler milk on the iron, zinc, iodine, and vitamin D status in young New Zealand children (n = 181; mean age 17 mo) were used. Adherence to the intervention was assessed by 7-d weighed diaries at wk 2, 7, 11, 15, and 19. Serum 25(OH)D concentration was measured at baseline and wk 20. Mean vitamin D intake provided by fortified milk was 3.7 μg/d (range, 0–10.4 μg/d). After 20 wk, serum 25(OH)D concentrations but not PTH were significantly different in the milk groups. The prevalence of having a serum 25(OH)D <50 nmol/L remained relatively unchanged at 43% in the meat group, whereas it significantly decreased to between 11 and 15% in those consuming fortified study milk. In New Zealand, vitamin D intake in young children is minimal. Our findings indicate that habitual consumption of vitamin D-fortified milk providing a mean intake of nearly 4 μg/d was effective in achieving adequate year-round serum 25(OH)D for most children.

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.

Preschoolers' physical activity, screen time, and compliance with recommendations

Purpose: Little evidence exists about the prevalence of adequate levels of physical activity and of appropriate screen-based entertainment in preschool children. Previous studies have generally relied on small samples. This study investigates how much time preschool children spend being physically active and engaged in screen-based entertainment. The study also reports compliance with the recently released Australian recommendations for physical activity (>=3 h·d-1) and screen entertainment (<=1 h·d-1) and the National Association for Sport and Physical Education physical activity guidelines (>=2 h·d-1) and American Academy of Pediatrics screen-based entertainment recommendations (<=2 h·d-1) in a large sample of preschool children.

Methods: Participants were 1004 Melbourne preschool children (mean age = 4.5 yr, range = 3–5 yr) and their families in the Healthy Active Preschool Years study. Physical activity data were collected by accelerometry during an 8-d period. Parents reported their child’s television/video/DVD viewing, computer/Internet, and electronic game use during a typical week. A total of 703 (70%) had sufficient accelerometry data, and 935 children (93%) had useable data on time spent in screen-based entertainment.

Results: Children spent 16% (approximately 127 min·d-1) of their time being physically active. Boys and younger children were more active than were girls and older children, respectively. Children spent an average of 113 min·d-1 in screen-based entertainment. Virtually no children (<1%) met both the Australian recommendations and 32% met both the National Association for Sport and Physical Education and American Academy of Pediatrics recommendations.

Conclusions: The majority of young children are not participating in adequate amounts of physical activity and in excessive amounts of screen-based entertainment. It is likely that physical activity may decline and that screen-based entertainment may increase with age. Compliance with recommendations may be further reduced. Strategies to promote physical activity and reduce screen-based entertainment in young children are required.

Digital natives? : new and old media and children’s language acquisition

The current generation of young children has been described as “digital natives”, having been born into a ubiquitous digital media environment. They are envisaged as educationally independent of the guided interaction provided by “digital immigrants”: parents and teachers. This paper uses data from the multiples waves of the Longitudinal Study of Australian Children (LSAC) to study the effect of various media on children’s development of vocabulary and traditional literacy. Previous research has suggested that time spent watching television is associated with less time spent reading, and ultimately, with inferior educational outcomes. The early studies of the “new” digital media (computers, games consoles, mobile phones, the Internet, etc.) assumed these devices would have similar effects on literacy outcomes to those associated with television. Moreover, these earlier studies relied on poorer measures of time spent in media use and usually did not control for the context of the child’s media use. Fortunately, LSAC contains measures of access to digital devices; parental mediation practices; the child’s use of digital devices as recorded in time use diaries; direct measures of the child’s passive vocabulary; and teachers’ ratings of the child’s literacy. The analysis presented shows the importance of the parental context framing the child’s media use in promoting the acquisition of vocabulary, and suggests that computer (but not games) use is associated with more developed language skills. Independently of these factors, raw exposure to television is not harmful to learning, as previously thought.

Preservation of confucian values in early childhood education : a study of experts’ and educators’ views

Confucian values form the core of the Chinese culture, penetrating all levels of social life, and also set the standards for family, community and political behavior. The teaching of values is deemed to be an important aspect of young children’s education and usually the responsibility for this is seen to rest with the family. Much interest has been generated recently on the teaching of core values in early childhood curriculum in order to encourage tolerance, acceptance, trust, openness, and honesty in children. Research on Confucianism is popularly conducted in different cultural contexts all over the world. Furthermore research has shown that Confucianism continues to exert a major influence on the everyday lives of Asian communities. Given the interest in Confucian values, this research study was designed to examine the expressed views of three cohorts of professionals in Hong Kong about the preservation of such values and their application to early childhood teaching. This study confirmed the view that there is a need to preserve cultural values to enable the child to be accepted in the society, especially with the value of ‘Ren’ helping one to learn how to interact with others and with the value of ‘Li’ further defining the appropriate behaviour in this interaction.

Promoting obesity prevention together with environmental sustainability

There is mounting evidence that current food production, transport, land use and urban design negatively impact both climate change and obesity outcomes. Recommendations to prevent climate change provide an opportunity to improve environmental outcomes and alter our food and physical activity environments in favour of a ‘healthier’ energy balance. Hence, setting goals to achieve a more sustainable society offers a unique opportunity to reduce levels of obesity. In the case of children, this approach is supported with evidence that even from a young age they show emerging understandings of complex environmental issues and are capable of both internalizing positive environmental values and influencing their own environmental outcomes. Given young children's high levels of environmental awareness, it is easy to see how environmental sustainability messages may help educate and motivate children to make ‘healthier’ choices. The purpose of this paper is to highlight a new approach to tackling childhood obesity by tapping into existing social movements, such as environmental sustainability, in order to increase children's motivation for healthy eating and physical activity behaviours and thus foster more wholesome communities. We contend that a social marketing framework may be a particularly useful tool to foster behaviour change beneficial to both personal and environmental health by increasing perceived benefits and reducing perceived costs of behaviour change. Consequently, we propose a new framework which highlights suggested pathways for helping children initiate and sustain ‘healthier’ behaviours in order to inform future research and potentially childhood obesity intervention strategies.

TV viewing behaviour among preschoolers : implications for public health recommendations

Excessive television (TV) viewing in early childhood has been associated with adverse cognitive and behavioural outcomes.[1-3] A recent review of the literature revealed that TV viewing in the formative pre-school years has also been linked with other health concerns including sleep difficulties, increased aggression, anxiety and obesity.[4] Given that early childhood is the time in which the foundations for future behaviours and habits are established and evidence shows that TV behaviours track from early childhood to adolescence,[5] it is not surprising that there has been much interest in determining an ‘appropriate’ amount of screen time for pre-schoolers. The aim of this paper is to review current recommendations around Australian pre-school children's TV use and the implications of these guidelines when we consider current data pertaining to young children's TV viewing behaviour.

Play-based learning

This chapter develops themes providing insights into the meaning of play-based learning and what it means to practitioners working in a range of contexts with early learners in the age range of birth to eight years. Play-based learning is defined as young learners constructing knowledge as they explore, experiment, discover and solve problems in playful and unique ways. Development is linked to play and viewed as a pattern of continuous, interrelated changes that begins at birth and continue through life span whilst learning is a change in behaviour. In the early years it is through experience in play that learning occurs. The definition of curriculum in this chapter presents a context for young learners demonstrating how play-based learning is fundamental to the well-being of young learners, be they infants, babies, toddlers, pre-schoolers or school aged children.

The diversity of backgrounds of young learners is recognised and provision has to be made in the curriculum for a rich diversity of learners. The Chapter also considers how a socio-constructivist theoretical orientation in the curriculum can be created with children and adults co-constructing knowledge with play-based learning as the framework.

A content analysis of early childhood teachers’ theoretical and practical experiences with infants and toddlers in Australian teacher education programs

 In Australia, the growth in the provision of early childhood services for very young children aged birth to three years has placed increased demands on pre-service teachers as new policy stipulates the need for qualified early childhood teachers. While many teacher education programs offer early childhood courses, they have traditionally had a greater focus on kindergarten and the formal years of schooling. Less is known about the amount of time devoted to developing the specialist educational capacity for teaching and caring for infants and toddlers. This paper explores 55 Australian early childhood teacher undergraduate education programs to provide data regarding what pre-service teachers learn about children from birth to three years of age during their formal program of study. It explores: if pre-service teachers engage in practical experiences with this age range; what content they learn; and how knowledge for this age range is assessed. Utilising information from fully accessible public program websites, data in the form of course details were examined to reveal the extent and nature of courses inclusive of teaching and learning focusing on children aged from birth to three years. Of the 55 programs, 18 programs provided practical experience with infants and toddlers, and to a lesser extent content was evident and assessed. Most of the programs which included a focus on birth to three years of age were delivered by Victorian institutions. Findings are important for the future of early childhood teacher education in Australia and hold key messages for teacher registration bodies.

Feasibility study to objectively assess activity and location of Hispanic preschoolers: a short communication

Abstract. Both physical and social environmental factors influence young children’s physical activity, yet little is known about where Hispanic children are more likely to be active. We assessed the feasibility of simultaneously measuring, then processing objective measures of location and physical activity among Hispanic preschool children. Preschool-aged Hispanic children (n = 15) simultaneously wore QStarz BT100X global positioning system (GPS) data loggers and Actigraph GT3X accelerometers for a 24- to 36-hour period, during which time their parents completed a location and travel diary. Data were aggregated to the minute and processed using the personal activity location measurement system (PALMS). Children successfully wore the GPS data loggers and accelerometers simultaneously, 12 of which yielded data that met quality standards. The average percent correspondence between GPS- and diary-based estimates of types of location was high and Kappa statistics were moderate to excellent, ranging from 0.49-0.99. The between method (GPS monitor, parent-reported diary) correlations of estimated participant-aggregated minutes spent on vehicle-based trips were strong. The simultaneous use of GPS and accelerometers to assess Hispanic preschool children’s location and physical activity is feasible. This methodology has the potential to provide more precise findings to inform environmental interventions and policy changes to promote physical activity among Hispanic preschool children.

Grandparents as educators and carers in China

Many grandparents play a significant role as educators and carers of children in the preschool years. Recently, this role has become the focus of much early childhood research as challenges facing grandparent carers and grandparent-headed households increasingly become an economic and social issue. Using survey data from China we explore the role of grandparents who have a primary care responsibility for a young child and discuss this contribution to the family in relation to quality of care and education. We argue that grandparents play a significant role in terms of home education of the young, workforce support for young parents, cultural identity within families and community capacity building. Grandparents are therefore deserving of more sustained attention from policy makers and educators when considering the young child's developmental environment.

A health promotion intervention can affect diet quality in early childhood

Initiatives to promote children’s nutrition and prevent childhood obesity are vital. Dietary patterns are a useful way to characterize whole diets, though no previous early childhood health promotion trial has assessed intervention impact using this approach. This research aimed to assess the effect on young children’s dietary patterns of a healthy eating and physical activity intervention. The Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program was a health promotion cluster-randomized controlled trial involving 542 families. Child diets were assessed by multiple 24-hour recalls post-intervention, at approximately 18 months of age. An Obesity Protective Dietary Index was created, and dietary patterns were also assessed by principal components analysis. These outcomes were used to compare intervention and control participants to test the effectiveness of the intervention. Children in the intervention arm scored significantly higher (15.6 ± 5.9) than those in the control arm (14.5 ± 6.7) for the Obesity Protective Dietary Index (scores out of 30, p=0.01). Three dietary patterns were identified by principal components analysis, however, scores were not significantly different between intervention and control arms. In conclusion, this paper presents novel results in both the evaluation of an early childhood health promotion intervention and in the assessment of child dietary patterns. The results highlight the capacity for such an initiative to improve child diets, and the need for further research in this area.

Early childhood predictors of toddlers' physical activity: longitudinal findings from the Melbourne InFANT program

Background: 

The potential link between gut microbiota and IgE-mediated food allergy in early life

There has been a dramatic rise in the prevalence of IgE-mediated food allergy over recent decades, particularly among infants and young children. The cause of this increase is unknown but one putative factor is a change in the composition, richness and balance of the microbiota that colonize the human gut during early infancy. The coevolution of the human gastrointestinal tract and commensal microbiota has resulted in a symbiotic relationship in which gut microbiota play a vital role in early life immune development and function, as well as maintenance of gut wall epithelial integrity. Since IgE mediated food allergy is associated with immune dysregulation and impaired gut epithelial integrity there is substantial interest in the potential link between gut microbiota and food allergy. Although the exact link between gut microbiota and food allergy is yet to be established in humans, recent experimental evidence suggests that specific patterns of gut microbiota colonization may influence the risk and manifestations of food allergy. An understanding of the relationship between gut microbiota and food allergy has the potential to inform both the prevention and treatment of food allergy. In this paper we review the theory and evidence linking gut microbiota and IgE-mediated food allergy in early life. We then consider the implications and challenges for future research, including the techniques of measuring and analyzing gut microbiota, and the types of studies required to advance knowledge in the field.
