Sleep duration and risk of obesity among a sample of Victorian school children

BACKGROUND: Insufficient sleep is potentially an important modifiable risk factor for obesity and poor physical activity and sedentary behaviours among children. However, inconsistencies across studies highlight the need for more objective measures. This paper examines the relationship between sleep duration and objectively measured physical activity, sedentary time and weight status, among a sample of Victorian Primary School children.

METHODS: A sub-sample of 298 grades four (n = 157) and six (n = 132) Victorian primary school children (aged 9.2-13.2 years) with complete accelerometry and anthropometry data, from 39 schools, were taken from a pilot study of a larger state based cluster randomized control trial in 2013. Data comprised: researcher measured height and weight; accelerometry derived physical activity and sedentary time; and self-reported sleep duration and hypothesised confounding factors (e.g. age, gender and environmental factors).

RESULTS: Compared with sufficient sleepers (67 %), those with insufficient sleep (<10 hrs/day) were significantly more likely to be overweight (OR 1.97, 95 % CI:1.11-3.48) or obese (OR 2.43, 95 % CI:1.26-4.71). No association between sleep and objectively measured physical activity levels or sedentary time was found.

CONCLUSION: The strong positive relationship between weight status and sleep deprivation merits further research though PA and sedentary time do not seem to be involved in the relationship. Strategies to improve sleep duration may help obesity prevention initiatives in the future.

21st century literacy : perceptions of and influences on year 6 teachers in Victorian classrooms

This paper presents a study of teachers’ perceptions of ‘21st century literacy’ practices and the dilemmas teacher face when these perceptions clash with the policies and the practices they feel are expected of them. Using narrative inquiry as its methodology, the paper presents 3 themes identified within the study, namely: ‘Teachers’ insights into 21st century literacy, ‘Teachers’ perceptions of necessary 21st century literacy skills for Year 6 students’ and ‘Influences on teachers’ literacy pedagogical decision-making and practice’. The narratives present two teachers’ perceptions (and misperceptions) of 21st century literacy, their pedagogical approaches, and how various factors influence their work. The paper considers how various factors influence teachers’ pedagogical practices, and highlights discrepancies between teachers’ professional beliefs and their practices based on external classroom influences. Narrative offers an insider’s view of how these discrepancies are lived out in two Victorian classrooms.

Gender difference in treatment and mortality of patients with ST-segment elevation myocardial infarction admitted to Victorian public hospitals: A retrospective database study.

BACKGROUND: Death from acute coronary syndrome (ACS) is avoidable with early reperfusion therapy, however, evidence suggests inequity in women's ACS treatment within a number of international healthcare systems, when compared to men's. Research indicates mortality rates are higher in some age groups of women when compared to men for the sub-group of ACS known as ST-segment elevation myocardial infarction (STEMI). OBJECTIVE: To determine whether patient sex was associated with patterns of reperfusion treatment variation or increased inhospital mortality in patients with STEMI. METHODS: We undertook retrospective analyses on a government database for patients admitted to Victorian public hospitals with STEMI. Patients were categorised into two age groups: 18-64 and 65-84 years (inclusive), to determine whether patient sex and these age groups influenced treatment from 2005 to 2008 and mortality from 2005 to 2010. RESULTS: Both younger and older women received less frequent angioplasty with stent and more often received no reperfusion treatment than men in corresponding younger and older age groups (p=0.006 and p<0.001, respectively). Overall, women in both age groups were more likely to die inhospital than men from equivalent age groups with STEMI (p<0.001, both groups). CONCLUSIONS: Proportionately, both younger and older women received less interventional reperfusion therapy for STEMI than their male cohorts, and died more often during admission than men. Further research needs to be undertaken to verify the findings and causes, and guide future research to ensure application of evidence to treatment in patients with STEMI.

Composition of objectively measured physical activity and sedentary behaviour participation across the school-day, influence of gender and weight status: cross-sectional analyses among disadvantaged Victorian school children

BACKGROUND: The after-school period has been described as the 'critical window' for physical activity (PA) participation. However, little is known about the importance of this window compared with the before and during-school period among socioeconomically disadvantaged children, and influence of gender and weight status.

METHODS: 39 out of 156 (RR=25%) invited primary schools across 26 local government areas in Victoria, Australia, consented to participate with 856 children (RR=36%) participating in the wider study. The analysis sample included 298 Grade 4 and Grade 6 children (mean age: 11.2±1.1; 44% male) whom met minimum accelerometry wear-time criteria and had complete height, weight and health-behaviours questionnaire data. Accelerometry measured duration in daily light-intensity PA (LPA), moderate-to-vigorous PA (MVPA) and sedentary time (ST) was calculated for before-school=8-8:59, during-school=9:00-15:29 and after-school=15:30-18:00. Bivariate and multivariable linear regression analyses were conducted.

RESULTS: During-school represented the greatest accumulation of LPA and MVPA compared with the before and after-school periods. Boys engaged in 102 min/day of LPA (95% CI 98.5 to 104.9) and 62 min/day of MVPA (95% CI 58.9 to 64.7) during-school; girls engaged in 103 min/day of LPA (95% CI 99.7 to 106.5) and 45 min/day of MVPA (95% CI 42.9 to 47.4). Linear regression models indicated that girls with overweight or obesity engaged in significantly less LPA, MVPA and more time in ST during-school.

CONCLUSIONS: This study highlights the importance of in-school PA compared with after-school PA among socioeconomically disadvantage children whom may have fewer resources to participate in after-school PA.

Every day you learn something : learning for life? Neighbourhood houses, adult learning and transitions to higher education

This book comes from a research project titled ‘Lifelong Learning? Neighbourhood Houses, Adult Learning and Transitions to Higher Education’ (T Ollis, Starr, Ryan, Angwin, & Harrison, 2016). This research has examined adult learning in the context of Neighbourhood Houses in the regions of Geelong and South Western Victoria.The research was conducted in 2015 and 2016 and sought to examine the learning experiences of adult learners who participate in the education programs of Neighbourhood Houses. The focus was on second chance learners and their transition pathways to higher education such as TAFE and University. A second group of learners were identified during the research process – later life learners. These learners were engaging with Neighbourhood Houses for personal interest learning and social and community connection. This small book provides a snapshot of the stories of learners who were involved in this research. It tells the lived stories of the participants, which is important as learning and education are connected with the ongoing development of ourselves as human beings. Learning is essential to our personhood and impacts on adults in terms of their welfare, health and prosperity over a lifetime. Many of the learners’ stories outlined in this book reveal checkered histories of education. Some have experienced learning difficulties, others have experienced family trauma that prevented them from finishing secondary schooling. Some of the stories describe issues related to reskilling or retraining in later life, responding to industry changes and work in the Greater Geelong and South West regions. Others were pursuing recreation and social connection and came to the Neighbourhood Houses to learn crafts, writing, photography and computer literacy skills. In almost all accounts of learning in this book, individuals had experienced less social isolation by being connected to others in the unique social environment of Neighbourhood houses.

The disparity between human rights policy and parliamentary practice in Australia : a Victorian case study

Over the past decade alcohol-related violence in and around licensed premises has given rise to significant legislative, regulatory and operational policing developments. In Australia, the State of Victoria introduced police-imposed banning notices as part of a range of provisions and new powers targeting alcohol-related disorderly behaviour. Banning notices exemplify a broader shift towards discretionary, pre-emptive, regulatory, summary justice which circumvents the criminal law, dilutes individual rights, and reconfigures expectations of balance in the administration of justice. The legal principles upon which banning notices are based and the way in which they were enacted by the Victorian Parliament challenge both the purpose and specific requirements of Victoria’s Charter of Human Rights and Responsibilities Act 2006. Detailed analysis of the application of the Charter compliance processes to the banning notice provisions point to a notable disparity between the expectations of formal human rights policy and the reality of substantive practice. The broader effect of such a disconnect is potentially significant, but has been largely opaque to meaningful scrutiny.

Workplace "bargaining" and the wages/working time nexus: counting the cost of decentralisation

The impact of deregulation on dispersion of earnings in Victoria has been
acknowledged in the findings of the recent task force enquiry into industrial relations in Victoria. This paper argues that the link between hours worked and rates of pay has played a significant role in this increased dispersion. Drawing upon detailed analysis of hours and wages in Victorian agreements, data is presented on declining take-home pay flowing from the loss of penalty rates. This, we argue, is attributable to
the lack of substantive and procedural protections available to Victorian workers under schedule 1A of the Workplace Relations Act, and formerly under the Victorian Employee Relations Act, 1992. We contrast these findings with collective agreements trading off penalty rates certified by the Australian Industrial Relations Commission, and Australian Workplace Agreements approved by the Office of the Employment
Advocate. We conclude by suggesting there is a scale of fair outcomes attached to the wages/hours trade-off, directly attributable to the various institutional mechanisms now influencing Australian wage determination.
