Children's content regulation and the 'obesity epidemic'

Some 30 years ago, Australia introduced the Children's Television Standards (CTS) with the twin goals of providing children with high-quality local programs and offering some protection from the perceived harms of television. The most recent review of the CTS occurred in the context of a decade of increasing international concern at rising levels of overweight and obesity, especially in very young children. Overlapping regulatory jurisdictions and co-regulatory frameworks complicate the process of addressing pressing issues of child health, while rapid changes to the media ecology have both extended the amount of programming for children and increased the economic challenges for producers. Our article begins with an overview of the conceptual shifts in priorities articulated in the CTS over time. Using the 2007-09 Review of the CTS as a case study, it then examines the role of research and stakeholder discourses in the CTS review process and critiques the effectiveness of existing regulatory regimes, both in providing access to dedicated children's content and in addressing the problem of escalating obesity levels in the population.

Digital natives? New and old media and children's outcomes.

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 article uses data from the Longitudinal Study of Australian Children (LSAC) to study the development of vocabulary and traditional literacy in children aged from 0 to 8 years; their access to digital devices; parental mediation practices; children's use of digital devices as recorded in time-diaries; and, finally, the association between patterns of media use and family contexts on children's learning. The analysis shows the importance of the parental context in framing media use for acquiring 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.

The case of children's literature : colonial or anti-colonial?

Since Jacqueline Rose published The Case of Peter Pan in 1984, scholars in the field of children’s literature have taken up a rhetorical stance which treats child readers as colonised, and children’s books as a colonising site. This article takes issue with Rose’s rhetoric of colonisation and its deployment by scholars, arguing that it is tainted by logical and ethical flaws. Rather, children’s literature can be a site of decolonisation which revisions the hierarchies of value promoted through colonisation and its aftermath by adopting what Bill Ashcroft refers to as tactics of interpolation. To illustrate how decolonising strategies work in children’s texts, the article considers several alphabet books by Indigenous author-illustrators from Canada and Australia, arguing that these texts for very young children interpolate colonial discourses by valorising minority languages and by attributing to English words meanings produced within Indigenous cultures.

A study of rural preschool practitioners’ views on young children’s mathematical thinking

The project Mathematical Thinking of Preschool Children in Rural and Regional Australia: Research and Practice aimed to investigate views of preschool practitioners about young children’s mathematical thinking and development. Structured individual interviews were conducted with 64 preschool practitioners from rural areas of three Australian states. The questions focused on five broad themes: children’s mathematics learning, support for mathematics teaching, technology and computers, attitudes and feelings, and assessment and record keeping. We review results from the interview data for each of these themes, discuss their importance, and outline recommendations related to teacher education as well as resource development and research.

Parental influences on the diets of 2-5 year-old children : systematic review of interventions

During the early years, parents have a major influence on their children's diets, food choices and development of eating habits. However, research concerning the influence of parental feeding practices on young children's diets is limited. This paper presents a systematic review of intervention studies with parents of preschool children. The aim was to investigate the effectiveness of interventions that target parent nutrition knowledge and/or parenting practices with parents of young children aged two to five years in the development of healthy dietary habits. Seventeen studies were identified. Findings highlight the limited number of good quality studies in this age group. Limitations include design inconsistency and a lack of longitudinal data to evaluate sustainability. Research on parental understanding of healthy diets and specific parenting styles and feeding practices is lacking. Further insights into how parents can positively influence children's diets will come from quality longitudinal research examining both parent feeding practices and nutrition knowledge in this age group.

Physical activity levels and patterns of 19-month-old children

Purpose: It is a commonly held perception that most young children are naturally active and meet physical activity recommendations. However, there is no scientific evidence available on which to confirm or refute such perceptions. The purpose of this study was to describe the physical activity levels and patterns of Australian toddlers.


Methods: Physical activity and demographic data of two hundred ninety-five 19-month-old children from the Melbourne InFANT Program were measured using accelerometers and parent surveys. Validated cut points of 192–1672 and >1672 counts per minute were used to determine time spent in light- (LPA) and moderate-to-vigorous- (MVPA) intensity physical activity, respectively. To be included in the analysis, children were required to have four valid days of accelerometer data to provide an acceptable (>0.70) reliability estimate of LPA and MVPA. Physical activity data for different periods of the day were examined.


Results: On average, toddlers engaged in 184 min of LPA and 47 min of MVPA daily, and 90.5% met the current Australian physical activity recommendations for 0- to 5-yr-olds (180 min of LPA/MVPA per day). Physical activity levels during mid morning and mid afternoon were higher than those during other periods. Physical activity patterns for boys and girls were similar, although boys engaged in more physical activity during the morning hours than girls did.


Conclusions: Most children meet the physical activity recommendations, although the majority of activity undertaken in the study was of light intensity. Boys were more active than girls were in the morning hours, but there were no differences between sexes over the entire day. Certain periods of the day may hold more promise for intervention implementation than others do.

Subjective wellbeing in children

This research proposed and applied guidelines for the investigation of subjective experience in young children. The results show that children normally experience positive wellbeing, and can reliably report this. However they rely upon adults for the protection and maintenance of subjective wellbeing, until they are cognitively mature enough to do so for themselves.

Patterns of physical activity and sedentary behaviour in preschool children

Background
Little is known about patterns of sedentary behavior (SB) and physical activity among preschoolers. Therefore, in this observational study patterns of SB and moderate-to-vigorous physical activity (MVPA) were examined in detail throughout the week in preschool-aged boys and girls.

Methods
A sample of 703 Melbourne preschool children (387 boys; 4.6 ± 0.7 y) were included in data analysis. SB and MVPA data were collected using accelerometry over an eight-day period. Percentage of time per hour in SB and in MVPA between 08:00 h and 20:00 h was calculated. Multi-level logistic regression models were created to examine the hour-by-hour variability in SB and MVPA for boys and girls across weekdays and weekend days. Odds ratios (OR) were calculated to interpret differences in hour-by-hour SB and MVPA levels between boys and girls, and between weekdays and weekend days.

Results
The highest SB levels co-occurred with the lowest MVPA levels from the morning till the early afternoon on weekdays, and during the morning and around midday on weekends. Besides, participation in SB was the lowest and participation in MVPA was the highest from the mid afternoon till the evening on weekdays and weekend days. The variability across the hours in SB and, especially, in MVPA was rather small throughout weekdays and weekends. These patterns were found in both boys and girls. During some hours, girls were found to be more likely than boys to demonstrate higher SB levels (OR from 1.08 to 1.16; all p < 0.05) and lower MVPA levels (OR from 0.75 to 0.88; all p < 0.05), but differences were small. During weekends, hour-by-hour SB levels were more likely to be lower (OR from 0.74 to 0.98; all p < 0.05) and hour-by-hour MVPA levels were more likely to be higher (OR from 1.15 to 1.50; all p < 0.05), than during weekdays, in boys and girls.

Conclusion
Entire weekdays, especially from the morning till the early afternoon, and entire weekend days are opportunities to reduce SB and to promote MVPA in preschool-aged boys and girls. Particularly weekdays hold the greatest promise for improving SB and MVPA. No particular time of the week was found where one sex should be targeted.

Early peer play interactions of resilient children living in disadvantaged communities

Resilience for children is positive adaptation and a capacity to thrive despite challenging circumstances. Children demonstrating resilience are seen to have strong cognitive skills and have developed positive peer relationships. The ‘Supporting Resilience’ project is exploring the conditions and characteristics of resilience of young children and their families who live in rural, regional and metropolitan communities that are economically and socially disadvantaged. The aim of this paper was to report on pretend play and social competence within the early years’ cohort of the ‘Supporting Resilience’ project. Twenty-six children aged 4–6 years who were identified as resilient by their preschool teacher were involved in the study. Results obtained from the Child Initiated Pretend Play Assessment and the Penn Interactive Peer Play Scale when the children were at pre-school found significant relationships between object substitution and social interaction (r = .414, p < .05). Children who could elaborate play with unstructured objects were less likely to be socially disconnected (r = –.49, p < .05). There was no significant difference between geographical locations for play ability. Significant difference for social competence was found between geographical locations. By situating play as individual development within a socio-cultural environment the relationship between children's pretend play ability and social peer play interactions are considered within early childhood development and resilience literature.

Children's physical activity and screen time : qualitative comparison of views of parents of infants and preschool children

Background
While parents are central to the development of behaviours in their young children, little is known about how parents view their role in shaping physical activity and screen time behaviours.

Methods
Using an unstructured focus group design, parental views and practices around children′s physical activity and screen time (television and computer use) were explored with eight groups of new parents (n=61; child age <12 months) and eight groups of parents with preschool-aged (3–5 year old) children (n=36) in Melbourne, Australia.

Results
Parents generally believed children are naturally active, which may preclude their engagement in strategies designed to increase physical activity. While parents across both age groups shared many overarching views concerning parenting for children′s physical activity and screen time behaviours, some strategies and barriers differed depending on the age of the child. While most new parents were optimistic about their ability to positively influence their child′s behaviours, many parents of preschool-aged children seemed more resigned to strategies that worked for them, even when aware such strategies may not be ideal.

Conclusions
Interventions aiming to increase children′s physical activity and decrease screen time may need to tailor strategies to the age group of the child and address parents′ misconceptions and barriers to optimum parenting in these domains.

Parental influences of the diets of 2-5-year-old children: systematic review of interventions

During the early years, parents have a major influence on their children’s diets, food choices and development of eating habits. However, research concerning the influence of parental feeding practices on young children’s diets is limited. This paper presents a systematic review of intervention studies with parents of preschool children. The aim was to investigate the effectiveness of interventions that target parent nutrition knowledge and/or parenting practices with parents of young children aged two to five years in the development of healthy dietary habits. Seventeen studies were identified. Findings highlight the limited number of good quality studies in this age group. Limitations include design inconsistency and a lack of longitudinal data to evaluate sustainability. Research on parental understanding of healthy diets and specific parenting styles and feeding practices is lacking. Further insights into how parents can positively influence children’s diets will come from quality longitudinal research examining both parent feeding practices and nutrition knowledge in this age group.

Children's media use : perspectives from social research

The paper explains the impacts of digital media on previously observed developmental patterns of time choices for the current generation of young children, age 5-11. It shows that work and family routines still influence patterns of media use, rather than just broadcast media schedules and access to digital and mobile devices. Contrary to previous research on digital natives that predicted that interactive media would eventually displace traditional linear media, these findings from a nationally-representative study show that time-use of 'lean back media' and 'lean forward media' run in parallel for Australian children 5-11.

Prospective evaluation of respiratory exacerbations in children with cystic fibrosis from newborn screening to 5 years of age

Background Newborn screening allows novel treatments for cystic fibrosis (CF) to be trialled in early childhood before irreversible lung injury occurs. As respiratory exacerbations are a potential trial outcome variable, we determined their rate, duration and clinical features in preschool children with CF; and whether they were associated with growth, lung structure and function at age 5 years. Methods: Respiratory exacerbations were recorded prospectively in Australasian CF Bronchoalveolar Lavage trial subjects from enrolment after newborn screening to age 5 years, when all participants underwent clinical assessment, chest CT scans and spirometry. Results 168 children (88 boys) experienced 2080 exacerbations, at an average rate of 3.66 exacerbations per person-year; 80.1% were community managed and 19.9% required hospital admission. There was an average increase in exacerbation rate of 9% (95% CI 4% to 14%; p<0.001) per year of age. Exacerbation rate differed by site (p<0.001) and was 26% lower (95% CI 12% to 38%) in children receiving 12 months of prophylactic antibiotics. The rate of exacerbations in the first 2 years was associated with reduced forced expiratory volume in 1 s z scores. Ever having a hospitalmanaged exacerbation was associated with bronchiectasis (OR 2.67, 95% CI 1.13 to 6.31) in chest CT scans, and lower weight z scores at 5 years of age (coefficient -0.39, 95% CI -0.74 to -0.05). Conclusions Respiratory exacerbations in young children are markers for progressive CF lung disease and are potential trial outcome measures for novel treatments in this age group.

The cost of healthcare for children with mental health difficulties

Objective: Childhood mental health difficulties affect one in every seven children in Australia, posing a potential financial burden to society. This paper reports on the early lifetime individual and population non-hospital healthcare costs to the Australian Federal Government for children experiencing mental health difficulties. It also reports on the use and cost of particular categories of service use, including the Medicare Benefits Schedule (MBS) mental health items introduced in 2006.
