A cluster-randomized controlled trial to reduce sedentary behavior and promote physical activity and health of 8-9 year olds : the transform-us! study

Background: Physical activity (PA) is associated with positive cardio-metabolic health and emerging evidence suggests sedentary behavior (SB) may be detrimental to children’s health independent of PA. The primary aim of the Transform-Us! study is to determine whether an 18-month, behavioral and environmental intervention in the school and family settings results in higher levels of PA and lower rates of SB among 8-9 year old children compared with usual practice (post-intervention and 12-months follow-up). The secondary aims are to determine the independent and combined effects of PA and SB on children’s cardio-metabolic health risk factors; identify the factors that mediate the success of the intervention; and determine whether the intervention is cost-effective.
Methods/design: A four-arm cluster-randomized controlled trial (RCT) with a 2 × 2 factorial design, with schools as the unit of randomization. Twenty schools will be allocated to one of four intervention groups, sedentary behavior (SB-I), physical activity (PA-I), combined SB and PA (SB+PA-I) or current practice control (C), which will be evaluated among approximately 600 children aged 8-9 years in school year 3 living in Melbourne, Australia. All children in year 3 at intervention schools in 2010 (8-9 years) will receive the intervention over an 18-month period with a maintenance ‘booster’ delivered in 2012 and children at all schools will be invited to participate in the evaluation assessments. To maximize the sample and to capture new students arriving at intervention and control schools, recruitment will be on-going up to the post-intervention time point. Primary outcomes are time spent sitting and in PA assessed via accelerometers and inclinometers and survey.
Discussion: To our knowledge, Transform-Us! is the first RCT to examine the effectiveness of intervention strategies for reducing children’s overall sedentary time, promoting PA and optimizing health outcomes. The integration of consistent strategies and messages to children from teachers and parents in both school and family settings is a critical component of this study, and if shown to be effective, may have a significant impact on educational policies as well as on pedagogical and parenting practices.

Associations between dietary patterns at 6 and 15 months of age and sociodemographic factors

BACKGROUND/OBJECTIVES: Data from the Avon Longitudinal Study of Parents and Children (ALSPAC) have previously shown that dietary patterns are observable by 3 years. However, it is not clear when dietary patterns emerge. We aimed to describe dietary patterns in early life and their associations with maternal and infant sociodemographic characteristics.

SUBJECTS/METHODS: Principal component analysis was applied to diet questionnaires of ALSPAC participants at 6 months (n=7052) and 15 months (n=5610) to extract dietary patterns. The sociodemographic factors associated with dietary patterns were investigated using regression analyses.

RESULTS: Four dietary patterns were extracted at both 6 and 15 months. A traditional-style pattern characterized by home-prepared meats, vegetables and desserts, a second pattern characterized by ready-prepared baby foods and a third pattern characterized by discretionary foods such as biscuits, sweets and crisps were identified at both ages. At 6 months, the fourth pattern was characterized predominantly by breastfeeding and at 15 months, by contemporary-style foods including herbs, legumes, nuts, raw fruit and vegetables. Higher maternal age and education, number of siblings and lower body mass index (BMI) was associated with higher scores on the breastfeeding or meat, vegetables and desserts patterns, whereas higher discretionary food pattern scores were associated with younger maternal age, lower education, higher BMI and more siblings. Associations between sociodemographic factors and the ready-prepared baby food pattern scores were inconsistent across ages.

CONCLUSIONS: Dietary patterns emerge from infancy and are associated with sociodemographic characteristics.

Cohort profile : The resilience for eating and activity despite inequality (READI) study

The Resilience for Eating and Activity Despite Inequality (READI) cohort was established to address the following two key aims: to investigate the pathways (personal, social and structural) by which socio-economic disadvantage influences lifestyle choices associated with obesity risk (physical inactivity, poor dietary choices) and to explore mechanisms underlying ‘resilience’ to obesity risk in socio-economically disadvantaged women and children. A total of 4349 women aged 18–46 years and 685 children aged 5–12 years were recruited from 80 socio-economically disadvantaged urban and rural neighbourhoods of Victoria, Australia, and provided baseline (T1: 2007–08) measures of adiposity, physical activity, sedentary and dietary behaviours; socio-economic and demographic factors; and psychological, social and perceived environmental factors that might impact on obesity risk. Audits of the 80 neighbourhoods were undertaken at baseline to provide objective neighbourhood environmental data. Three-year follow-up data (2010–11) have recently been collected from 1912 women and 382 children. Investigators welcome enquiries regarding data access and collaboration.

Promoting physical activity and reducing sedentary behavior in disadvantaged neighborhoods : a qualitative study of what women want

Since women living in socioeconomically disadvantaged neighborhoods are more likely to be physically inactive and engage in higher levels of sedentary behavior than women living in more advantaged neighborhoods, it is important to develop and test the feasibility of strategies aimed to promote physical activity and reduce sedentary behavior amongst this high-risk target group. Thirty-seven women (aged 19–85) living in a disadvantaged neighborhood, and five key stakeholders, received a suite of potential intervention materials and completed a qualitative questionnaire assessing the perceived feasibility of strategies aimed to increase physical activity and reduce sedentary behavior. Thematic analyses were performed. Women perceived the use of a locally-relevant information booklet as a feasible strategy to increase physical activity and reduce sedentary behavior. Including weight-loss information was suggested to motivate women to be active. Half the women felt the best delivery method was mailed leaflets. Other suggestions included reference books and websites. Many women mentioned that an online activity calendar was motivational but too time-consuming to commit to. Most women preferred the information booklet as a strategy to increase physical activity/reduce sedentary behavior, yet several suggested that using the booklet together with the online calendar may be more effective. These findings make an important contribution to research informing the development of intervention strategies to increase physical activity and reduce sedentary behavior amongst women living in disadvantaged neighborhoods.

The drawer and the drawing

"The drawer and the drawing" is an installation that is a direct response to the Deakin artists books collection. Using original drawing, hand colouring, computer enhanced artwork, paper-cutouts, photographs, I created a glimpse of what the “book” tells me about the artist? I created "artworks, the books and the ephemera that was left over and behind when the “artbook” was taken away and placed in a gallery.

Discriminant validity of the sensory profile in Australian children with autism spectrum disorder

Objective. The discriminant validity of the Sensory Profile was evaluated by comparing the sensory processing scores of Australian children, 5 to 8 years of age, diagnosed with autism spectrum disorder (ASD) to a control group of children with typical development matched for age and gender. Method. Twenty-six parents of children with ASD and 26 parents of typically developing children without ASD completed the Sensory Profile. Sensory Profile category, factor, and quadrant scores were compared using multivariate analysis to investigate if there were differences between the two groups. Results. The results indicated that the children with ASD had significantly lower sensory processing scores on all fourteen categories, eight out of nine factors, and all four quadrants of the Sensory Profile. Conclusion. The results also provide evidence of discriminant validity of Sensory Profile scores between children with ASD and children with typical development. In addition, the study findings indicate that the Sensory Profile can be used with confidence in cross-cultural contexts, such as Australia.

Calm active and focused : children���s responses to an organic outdoor learning environment

This study reports on children’s observed responses to natural features introduced in the redevelopment of a childcare centre garden. Using an action research approach, the redevelopment was based on the preferences of the director, staff and 18 three- to four-year-olds, as expressed through interviews, conversations, photographs and drawings. Adults and children overwhelmingly preferred natural elements. The kindergarten teacher and assistant observed children’s responses to the implementation of features including a teepee, mulch, greenery, flowers, and loose organic materials. In follow-up interviews, they reported positive child responses including: richer imaginative play; increased physical activity; calmer, more focused play; and positive social interactions. These findings provide further evidence of the importance of providing children with naturalized outdoor play spaces.

A review of the impact of different types of leading interview questions on child and adult witnesses with intellectual disabilities

Children and adults with intellectual disabilities have traditionally been considered poor witnesses because they are easily misled and produce less accurate information in interviews when compared with individuals without intellectual disabilities. However, witnesses’ levels of accuracy depend on the types of questions that they are asked, such as whether they are open or closed and whether they contain misleading information. In the current systematic review, we examined the literature investigating the different types of misleading questions commonly used in interviews, and their influence on the memories of adults and children with and without an intellectual disability. Thirteen articles that met inclusion criteria were reviewed. It was found that, compared with other question types, open and closed questions that presumed certain information to be true elicited the greatest number of errors in children and adults with intellectual disabilities compared with other question types. These findings reinforce the notion that the onus is on interviewers – particularly when interviewing vulnerable witnesses – to avoid leading questions that presume information that may not be true.

Historiographic foodways: a survey of food and drink histories in Australia

This essay is a survey of the field of food and drink history in Australia since the 1970s. It discusses the range of research and picks out key historiographic aspects: the search for an Australian cuisine; regional food cultures; connection between sources and historical interpretation; and the interdisciplinarity of food and drink history. It suggests that as food and drink histories have broadened beyond a search for culinary traditions and a gastronomic sensibility, so our understanding of food and drink in Australian history has deepened. It also argues that food and drink history is more than textual knowledge in books and articles: television programs and exhibitions held in museums and libraries, for example, have enhanced our understanding of food and drink histories.

Equivalence and relational thinking: opportunities for professional learning

In this article an argument for the use of collaborative professional learning teams to improve teaching and children's achievement is presented together with an explanation of how this can be done. The case provided in this article concerns children's understanding of equivalence and the way in which teachers together can explore children's conceptions and misconceptions held by children in their classroom. An effective teaching strategy using a number talk about a true/false number sentence is also described.

Thirteen-year trends in child and adolescent fundamental movement skills: 1997-2010

Maternal and early postnatal nutrition and mental health of offspring by age 5 years: a prospective cohort study clinical guidance

Objective
Diet quality is related to the risk for depression and anxiety in adults and adolescents; however, the possible impact of maternal and early postnatal nutritional exposures on children’s subsequent mental health is unexplored.

Method
The large prospective Norwegian Mother and Child Cohort Study recruited pregnant women between 1999 and 2008. Data were collected from mothers during pregnancy and when children were 6 months and 1.5, 3, and 5 years of age. Latent growth curve models were used to model linear development in children’s internalizing and externalizing problems from 1.5 to 5 years of age as a function of diet quality during pregnancy and at 1.5 and 3 years. Diet quality was evaluated by dietary pattern extraction and characterized as “healthy” or “unhealthy.” The sample comprised 23,020 eligible women and their children. Adjustments were made for variables including sex of the child, maternal depression, maternal and paternal age, maternal educational attainment, household income, maternal smoking before and during pregnancy, mothers’ parental locus of control, and marital status.

Results
Higher intakes of unhealthy foods during pregnancy predicted externalizing problems among children, independently of other potential confounding factors and childhood diet. Children with a high level of unhealthy diet postnatally had higher levels of both internalizing and externalizing problems. Moreover, children with a low level of postnatal healthy diet also had higher levels of both internalizing and externalizing problems.

Conclusion
Among this large cohort of mothers and children, early nutritional exposures were independently related to the risk for behavioral and emotional problems in children.

Parental factors associated with obesity in children with disability: a systematic review

The current literature on obesity in typically developing children shows that the family context, and specifically the way parents parent their children are major determinants of childhood obesity. The influence of these factors on obesity in children with disability, however, remains unclear. A systematic review of the literature was undertaken to identify the parental and parenting risk factors associated with obesity in children and adolescents with disability. Articles were identified through Medline, Academic Search Complete, PsycINFO, ProQuest, ISI, CINAHL, Cochrane and Scopus databases. There was no restriction on publication dates. The inclusion criteria were empirical papers that tested associations between parental and parenting risk factors and obesity in children and adolescents with intellectual and other developmental disabilities. Only 11 studies met the selection criteria and subsequently included in this review. Results suggest that obesity in children and adolescents with disability may be associated with socioeconomic status; parents' body mass index, perception and attitude towards their children's weight and physical activity; and levels of activity in both parents and children. Firm conclusions about these associations cannot be reached, however, due to mixed findings and methodological limitations of the studies. Recommendations for future research are provided.
