Trends in child and adolescent obesity prevalence according to socioeconomic position: protocol for a systematic review

BACKGROUND: Obesity is a significant public health issue and is socially patterned, with greater prevalence of obesity observed in the most socioeconomically disadvantaged groups. Recent evidence suggests that the prevalence of childhood obesity is levelling off in some countries. However, this may not be the case across all socioeconomic strata. The aim of this review is to examine whether trends in child and adolescent obesity prevalence since 1990 differ according to socioeconomic position in developed countries.

METHODS: An electronic search will be conducted via Ovid Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Scopus and Cochrane Collaboration to identify articles that report trends in obesity prevalence in children and adolescents according to socioeconomic position. We will also search grey literature databases including the Virtual Library for Public Health and the System for Information on Grey Literature, as well as websites from relevant organisations. Articles that report on a series of cross sectional studies; describe one or more measure of obesity with data recorded at two or more time points since 1990; and report trends by at least one indicator of socioeconomic position will be included. Quality of included studies will be evaluated according to criteria that consider both internal and external validity. Descriptive analysis will be performed to examine trends since 1990 in childhood obesity prevalence according to socioeconomic position.

DISCUSSION: The review will provide a picture of change over time in developed countries of childhood obesity prevalence across socioeconomic strata and identify whether changes in childhood obesity prevalence are experienced equally across socioeconomic groups.

Mind the gap 2014 : research to inform the next five years of library development

Libraries have a long history of gathering evidence of performance. The results of regular client satisfaction surveys directly inform the continuous improvement of library and information services. Staff and student input is critical for improving library physical and virtual spaces, facilities and resources, and also to learn how the university community may approach information discovery into the future.

At Deakin University Library we are investigating, developing and integrating Web 2.0 applications into our service delivery. At the same time, designs for next generation physical learning spaces are being developed and implemented. These will extend the opportunities for students to contribute to a connected network of learners and teachers, to develop social networks, and to enrich experience of university life. Both the online and spaces strategies support the University’s distinctive advantage in flexible education.

But what of the future? How can the Library ensure that its support of research, teaching and learning aligns with changes in the behaviour and preferences of the university community in the next five years? This paper reviews Deakin University Library’s recent achievements, exposes an important gap and previews its plans to ensure its reliable support to the university community continues.

Linking and sharing data in the humanities and creative arts: building the HuNI Virtual Laboratory

The Humanities Networked Infrastructure (HuNI) is one of the national Virtual Laboratories that are being developed as part of the Australian government's National e-Research Collaboration Tools and Resources (NeCTAR) programme. This paper examines the methodologies and technical architecture being deployed by HuNI to link and share Australian data in the humanities and creative arts.
