Catching gender-Identity production in flight : making the commonplace visible

The purpose of this article is to develop and illustrate an approach for making the commonplace visible in a natural, as opposed to manipulated, social setting. The key research task was to find a way of capturing the ongoing production or enactment of the self that provides some insight into the way in which it is produced in a routine, matter of fact way. The article takes a number of steps to develop a research approach to the task. First, gender-identity was selected as a more specific aspect of self-production. Second, the concept of “flashpoints” was used to refer to a particular moment in the routine which achieves some significance or salience as a result of the participants seizing upon some otherwise unremarkable action or statement and twisting it to their purpose. In this study, the purpose was gender-identity creation. Primary school children in the classroom and their teachers were the participants of the study. Through the use of flashpoints, the article demonstrates how gender-identity production of these children can be caught in flight. The article concludes that this approach can be added to the researcher’s toolkit.

A framework for re-thinking learning in science from recent cognitive science perspectives

Recent accounts by cognitive scientists of factors affecting cognition imply the need to reconsider current dominant conceptual theories about science learning. These new accounts emphasize the role of context, embodied practices and narrative-based representation rather than learners’ cognitive constructs. In this paper we analyze data from a longitudinal study of primary school children’s learning to outline a framework based on these contemporary accounts, and to delineate key points of difference from conceptual change perspectives. The findings suggest this framework provides strong theoretical and practical insights into how children learn and the key role of representational negotiation in this learning. We argue that the nature and process of conceptual change can be re-interpreted in terms of the development of students’ representational resources.

Parental influence and obesity prevention in pre-schoolers : a systematic review of interventions

Obesity is difficult to reverse in older children and adults and calls have been made to implement obesity prevention strategies during the formative pre-school years. Childhood obesity experts suggest that prevention of overweight in the pre-school years should focus on parents, because parental beliefs, attitudes, perceptions and behaviours appear to contribute to children’s development of excessive weight gain. While evidence suggests that parental variables may be instrumental in the development of obesity, there has been no systematic evaluation of whether intervening to change such variables will positively influence the development of excess adiposity during the pre-school years. This paper is a conceptual and methodological review of the literature on the parental variables targeted in interventions designed to modify risk factors for obesity by promoting healthy eating and/or physical activity and/or reducing sedentary behaviours in families of children aged 2–6 years. There were significant methodological limitations of existing studies and the scientific study of this area is in its infancy. However, the results suggest that the modification of parental variables known to be associated with obesity-promoting behaviours in pre-school children may show promise as an obesity prevention strategy; further research is needed.

Changes in body mass index and health related quality of life from childhood to adolescence

Objective . To determine longitudinal relationships between body mass index (BMI) and health-related quality of life (HRQoL) in an adolescent population sample.
Design. Data collected in 2000 and 2005 within the Health of Young Victorians longitudinal cohort study.
Setting. Originally a community sample of elementary school students in Victoria, Australia. Follow-up occurred in either secondary schools or individuals homes.
Participants. Cohort recruited in 1997 via a random sampling design from Victorian elementary schools. Originally comprising 1 943 children, 1 569 (80.8%) participated in 2000 (wave 2, 8 – 13 years) and 851 (54%) in 2005 (wave 3, 13 – 19 years).
Main outcome measures. In both waves participants and their parents completed the PedsQL, a 23-item child HRQoL measure, and BMI z-scores and status (non-overweight, overweight or obese) were calculated from measured height and weight. Associations were tested cross-sectionally and longitudinally (linear regression, adjusted for baseline values)
Results. A total of 81.6% remained in the same BMI category, while 11.4% and 7.0% moved to higher and lower categories, respectively. Cross-sectional inverse associations between lower PedsQL and higher BMI categories were similar to those for elementary school children. Wave 2 BMI strongly predicted wave 3 BMI and wave 2 PedsQL strongly predicted wave 3 PedsQL. Only parent-reported Total PedsQL score predicted higher subsequent BMI, though this effect was small. Wave 2 BMI did not predict wave 3 PedsQL.
Conclusions. This novel study confi rmed previous cross-sectional associations, but did not provide convincing evidence that
BMI is causally associated with falling HRQoL or vice versa across the transition from childhood to adolescence.

Asthma among schoolchildren in the Barwon region of Victoria

Objectives: To determine (i) the relationship between asthma management and socioeconomic status; (ii) whether recent estimates from the International Study of Asthma and Allergies in Childhood (ISAAC) conducted in Melbourne apply to a broader cross-section of Victorian children; and (iii) age-related trends in asthma prevalence.

Design: A questionnaire survey, based on the ISAAC protocol.

Participants and setting: Subjects were children aged 4–13 years from a random sample of primary schools in the Barwon region of Victoria. The survey was conducted between March and September 2005.

Main outcome measures: Parent-reported wheeze and wheeze-related use of health resources during the preceding 12 months.

Results: Questionnaires were returned by 7813/9258 students (84%). Lower socioeconomic status was associated with increased frequency of regular asthma reviews (P < 0.01 for trend), but not of emergency department visits (P = 0.19). The prevalence of wheeze among 6- and 7-year-old children in the Barwon region was similar to that in Melbourne children (20.2% v 20.0%, respectively).There was an age-related increase in the proportion of children with ≥ 12 episodes of wheeze (P = 0.01); but an age-related decrease in emergency department visits (P = 0.02).

Conclusions: Disadvantaged children have good access to regular asthma reviews and are no more likely to attend an emergency department with an episode of acute wheeze. Asthma prevalence in 6- and 7-year-old children in the Barwon region is similar to that in Melbourne. The prevalence of children with very frequent wheeze increases with age, but their use of health resources decreases.

The factor structure of the Chinese family assessment instrument adapted for parent report

This article reports on a confirmatory factor analytic study of an adapted version of an instrument designed to assess family functioning of Chinese families. The Chinese Family Assessment Instrument, originally designed for completion by adolescents, was adapted for completion by parents. A sample of 700 parent dyads of elementary school children (382 girls and 318 boys) completed the adapted questionnaire. Initial factor analyses showed that the existing five-factor structure used for adolescents’ responses was not a good fit for these data. Instead, a four-factor solution emerged where the factors were positive family functioning, negative family functioning, tolerance for family members, and parental understanding. This structure was the same for both mothers and fathers. Further studies of the Chinese Family Assessment Instrument parent adaptation are required to test the factor structure that emerged. Following such studies, validation studies will be required.

Multilevel analysis of the Be Active Eat Well intervention : environmental and behavioural influences on reductions in child obesity risk

Background: The Be Active Eat Well (BAEW) community-based child obesity prevention intervention was successful in modestly reducing unhealthy weight gain in primary school children using a multi-strategy and multi-setting approach.

Objective: To (1) examine the relationship between changes in obesity-related individual, household and school factors and changes in standardised child body mass index (zBMI), and (2) determine if the BAEW intervention moderated these effects.

Methods: The longitudinal relationships between changes in individual, household and school variables and changes in zBMI were explored using multilevel modelling, with measurement time (baseline and follow-up) at level 1, individual (behaviours, n=1812) at level 2 and households (n=1318) and schools (n=18) as higher levels (environments). The effect of the intervention was tested while controlling for child age, gender and maternal education level.

Results: This study confirmed that the BAEW intervention lowered child zBMI compared with the comparison group (−0.085 units, P=0.03). The variation between household environments was found to be a large contributor to the percentage of unexplained change in child zBMI (59%), compared with contributions from the individual (23%) and school levels (1%). Across both groups, screen time (P=0.03), sweet drink consumption (P=0.03) and lack of household rules for television (TV) viewing (P=0.05) were associated with increased zBMI, whereas there was a non-significant association with the frequency the TV was on during evening meals (P=0.07). The moderating effect of the intervention was only evident for the relationship between the frequency of TV on during meals and zBMI, however, this effect was modest (P=0.04).

Conclusions: The development of childhood obesity involves multi-factorial and multi-level influences, some of which are amenable to change. Obesity prevention strategies should not only target individual behaviours but also the household environment and family practices. Although zBMI changes were modest, these findings are encouraging as small reductions can have population level impacts on childhood obesity levels.

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.

Physical Education can improve insulin resistance: The LOOK randomized cluster trial

Purpose
As impaired glucose metabolism may arise progressively during childhood, we sought to determine whether the introduction of specialist-taught school physical education (PE) based on sound educational principles could improve insulin resistance (IR) in elementary school children.

Methods
In this 4-yr cluster-randomized intervention study, participants were 367 boys and 341 girls (mean age = 8.1 yr, SD = 0.35) initially in grade 2 in 29 elementary schools situated in suburbs of similar socioeconomic status. In 13 schools, 100 min·wk−1 of PE, usually conducted by general classroom teachers, was replaced with two classes per week taught by visiting specialist PE teachers; the remaining schools formed the control group. Teacher and pupil behavior were recorded, and measurements in grades 2, 4, and 6 included fasting blood glucose and insulin to calculate the homeostatic model of IR, percent body fat, physical activity, fitness, and pubertal development.

Results
On average, the intervention PE classes included more fitness work than the control PE classes (7 vs 1 min, P < 0.001) and more moderate physical activity (17 vs 10 min, P < 0.001). With no differences at baseline, by grade 6, the intervention had lowered IR by 14% (95% confidence interval = 1%–31%) in the boys and by 9% (95% confidence interval = 5%–26%) in the girls, and the percentage of children with IR greater than 3, a cutoff point for metabolic risk, was lower in the intervention than the control group (combined, 22% vs 31%, P = 0.03; boys, 12% vs 21%, P = 0.06; girls, 32% vs 40%, P = 0.05).

Conclusions
Specialist-taught primary school PE improved IR in community-based children, thereby offering a primordial preventative strategy that could be coordinated widely although a school-based approach.

Sources, perceived usefulness and understanding of information disseminated to families who entered home quarantine during the H1N1 pandemic in Victoria, Australia: a cross-sectional study

Background Voluntary home quarantine of cases and close contacts was the main non-pharmaceutical intervention used to limit transmission of pandemic (H1N1) 2009 influenza (pH1N1) in the initial response to the outbreak of the disease in Australia. The effectiveness of voluntary quarantine logically depends on affected families having a clear understanding of what they are being asked to do. Information may come from many sources, including the media, health officials, family and friends, schools, and health professionals. We report the extent to which families who entered home quarantine received and used information on what they were supposed to do. Specifically, we outline their sources of information; the perceived usefulness of each source; and associations between understanding of recommendations and compliance. Methods Cross-sectional survey administered via the internet and computer assisted telephone interview to families whose school children were recommended to go into home quarantine because they were diagnosed with H1N1 or were a close contact of a case. The sample included 314 of 1157 potentially eligible households (27% response rate) from 33 schools in metropolitan Melbourne. Adjusting for clustering within schools, we describe self-reported 'understanding of what they were meant to do during the quarantine period'; source of information (e.g. health department) and usefulness of information. Using logistic regression we examine whether compliance with quarantine recommendations was associated with understanding and the type of information source used. Results Ninety per cent understood what they were meant to do during the quarantine period with levels of understanding higher in households with cases (98%, 95% CI 93%-99% vs 88%, 95% CI 84%-91%, P = 0.006). Over 87% of parents received information about quarantine from the school, 63% from the health department and 44% from the media. 53% of households were fully compliant and there was increased compliance in households that reported that they understood what they were meant to do (Odds Ratio 2.27, 95% CI 1.35-3.80). Conclusions It is critical that public health officials work closely with other government departments and media to provide clear, consistent and simple information about what to do during quarantine as high levels of understanding will maximise compliance in the quarantined population.

Leave entitlements, time off work and the household financial impacts of quarantine compliance during an H1N1 outbreak

Background The Australian state of Victoria, with 5.2 million residents, enforced home quarantine during a H1N1 pandemic in 2009. The strategy was targeted at school children. The objective of this study was to investigate the extent to which parents’ access to paid sick leave or paid carer’s leave was associated with (a) time taken off work to care for quarantined children, (b) household finances, and (c) compliance with quarantine recommendations. Methods We conducted an online and telephone survey of households recruited through 33 schools (85% of eligible schools), received 314 responses (27%), and analysed the subsample of 133 households in which all resident parents were employed. Results In 52% of households, parents took time off work to care for quarantined children. Households in which no resident parent had access to leave appeared to be less likely to take time off work (42% vs 58%, p=0.08) although this difference had only borderline significance. Among parents who did take time off work, those in households without access to leave were more likely to lose pay (73% vs 21%, p<0.001). Of the 26 households in which a parent lost pay due to taking time off work, 42% experienced further financial consequences such as being unable to pay a bill. Access to leave did not predict compliance with quarantine recommendations. Conclusions Future pandemic plans should consider the economic costs borne by households and options for compensating quarantined families for income losses.

Refractive errors in students from Middle Eastern backgrounds living and undertaking schooling in Australia

Background:  Environmental factors associated with schooling systems in various countries have been implicated in the rising prevalence of myopia, making the comparison of prevalence of refractive errors in migrant populations of interest. This study aims to determine the prevalence of refractive errors in children of Middle Eastern descent, raised and living in urban Australia but actively maintaining strong ties to their ethnic culture, and to compare them with those in the Middle East where myopia prevalence is generally low.Methods:  A total of 354 out of a possible 384 late primary/early secondary schoolchildren attending a private school attracting children of Middle Eastern background in Melbourne were assessed for refractive error and visual acuity. A Shin Nippon open-field NVision-K5001 autorefractor was used to carry out non-cycloplegic autorefraction while viewing a distant target. For statistical analyses students were divided into three age groups: 10–11 years (n = 93); 12–13 years (n = 158); and 14–15 years (n = 102).Results:  All children were bilingual and classified as of Middle Eastern (96.3 per cent) or Egyptian (3.7 per cent) origin. Ages ranged from 10 to 15 years, with a mean of 13.17 ± 0.8 (SEM) years. Mean spherical equivalent refraction (SER) for the right eye was +0.09 ± 0.07 D (SEM) with a range from -7.77 D to +5.85 D. The prevalence of myopia, defined as a spherical equivalent refraction 0.50 D or more of myopia, was 14.7 per cent. The prevalence of hyperopia, defined as a spherical equivalent refraction of +0.75 D or greater, was 16.4 per cent, while hyperopia of +1.50 D or greater was 5.4 per cent. A significant difference in SER was seen as a function of age; however, no significant gender difference was seen.Conclusions:  This is the first study to report the prevalence of refractive errors for second-generation Australian schoolchildren coming from a predominantly Lebanese Middle Eastern Arabic background, who endeavour to maintain their ethnic ties. The relatively low prevalence of myopia is similar to that found for other metropolitan Australian school children but higher than that reported in the Middle East. These results suggest that lifestyle and educational practices may be a significant influence in the progression of myopic refractive errors.

Process evaluation of a community-based intervention program: Healthy Youth Healthy Communities, an adolescent obesity prevention project in Fiji

Nearly one-half of the adult population in Fiji between the ages of 15–64 years is either overweight or obese; and rates amongst school children have, on average, doubled during the last decade. There is an urgent need to scale up the promotion of healthy behaviors and environments using a multi-sectoral approach. The Healthy Youth Healthy Community (HYHC) project in Fiji used a settings approach in secondary schools and faith-based organizations to increase the capacity of the whole community, including churches, mosques and temples, to promote healthy eating and regular physical activity, and to prevent unhealthy weight gain in adolescents aged 13–18 years. The team consisted of a study manager, project coordinator and four research assistants (RAs) committed to planning, designing and facilitating the implementation of intervention programs in collaboration with other stakeholders, such as the wider school communities, government and non-governmental organizations and business partners. Process data were collected on all intervention activities and analyzed by dose, frequency and reach for each specific strategy. The Fiji Action Plan included nine objectives for the school settings; four were based on nutrition and two on physical activity in schools, plus three general objectives, namely capacity building, social marketing and evaluation. Long-term change in nutritional behavior was difficult to achieve; a key contributor to this was the unhealthy food served in the school canteens. Whilst capacity-building proved to be one of the best mechanisms for intervening, it is important to consider the cultural and social factors influencing health behaviors and affecting specific groups.

Supporting resilience in early years classrooms: the role of the teacher

It is an accepted fact that resilience is a multifaceted phenomenon which has been proven to affect the learning, growth and development of individuals. A childs formative years are a time when resilience needs to be promoted so they can cope with the challenges of life. This paper reports some of the findings of an Australian Research Council-funded longitudinal study which investigated resilience in the context of significant transitions in the lives of children and young adults. This study explored the conditions and characteristics of resilience, looking at the educational, health, work-related or leisure interventions that support and foster resilience. Outlined in this paper are findings from the early years cohort of the study involving teachers pedagogy informing the practical approaches and strategies that promote and protect resilience in young children. It is argued that teachers working with young children need to be mindful of using enabling strategies in which their practice works purposively with the school environment and the building of relationships.
