Sedentary Behaviour Taxonomy – Round 1 Results Published in PLOS ONE

| December 18, 2013 | 0 Comments

SBRN members Sebastien Chastin and colleagues have recently published the results of the first round of their Sedentary Behaviour Taxonomy project.

The abstract (via PLOS ONE):


Over the last decade, sedentary behaviors have emerged as a distinctive behavioral paradigm with deleterious effects on health independent of physical activity. The next phase of research is to establish dose response between sedentary behaviors and health outcomes and improve understanding of context and determinants of these behaviors. Establishing a common taxonomy of these behaviors is a necessary step in this process.


The Sedentary behavior International Taxonomy project was developed to establish a classification of sedentary behaviors by use of a formal consensus process.


The study follows a Delphi process in three Rounds. A preparatory stage informed the development of terms of reference documents. In Round 1, experts were asked to make statements about the taxonomy; 1) its purpose and use ; 2) the domains, categories or facets that should be consider and include; 3) the structure/architecture to arrange and link these domains and facets. In Round 2 experts will be presented with a draft taxonomy emerging from Round 1 and invited to comment and propose alterations. The taxonomy will then be finalised at the outset of this stage.


Results of Round 1 are reported here. There is a general consensus that a taxonomy will help advances in research by facilitating systematic and standardised: 1) investigation and analysis; 2) reporting and communication; 3) data pooling, comparison and meta-analysis; 4) development of measurement tools; 4) data descriptions, leading to higher quality in data querying and facilitate discoveries. There is also a consensus that such a taxonomy should be flexible to accommodate diverse purposes of use, and future advances in the field and yet provide a cross-disciplinary common language. A consensual taxonomy structure emerged with nine primary facets (Purpose, Environment, Posture, Social, Measurement, Associated behavior, Status, Time, Type) and the draft structure presented here for Round 2.

New guide helps researchers decide how to measure sedentary behaviour

| October 1, 2013 | 2 Comments

Today’s post comes from Dr Dylan Cliff, a National Heart Foundation Postdoctoral Research Fellow at the University of Wollongong (Australia).

Many people interested in young people’s development are now aware that sedentary behaviours, particularly too much television viewing, can be harmful to health during childhood and adolescence. There are, however, currently a wide variety of approaches being used to measure sedentary behaviours in young people. This can make things confusing for those who are new to sedentary behaviour research such as clinicians, health promoters, educators, and researchers from different fields. It is important that researchers, practitioners and policy makers understand the strengths and weaknesses of different methods of assessing sedentary behaviours among young people, and have easy access to information about the most appropriate instruments to suit their needs.

With this in mind, members of the Physical Activity and Sedentary Behaviour Stream of the Australasian Child and Adolescent Obesity Research Network (ACAORN) have recently developed an online Method Selection Guide and published an accompanying ‘Hitchhiker’s Guide‘ to assist users in choosing instruments to measure sedentary behaviours among children and adolescents. This followed on from a systematic review conducted by the Stream to summarise the evidence on the validity and reliability of available measures of sedentary behaviours.

For the Method Selection Guides, Stream members developed decision flow charts to assist users in selecting an appropriate measure, identified attributes of each method and described five case scenarios to illustrate considerations associated with the selection of each method of measurement. The scenarios included a screen time intervention among preschoolers, a school-based intervention to reduce sitting during class-time among children, a treatment program for overweight/obese school children focused on reducing sedentary time, the primary prevention of adolescent screen time in a clinical setting, and an observational study to estimate the population prevalence of screen time among adolescents. In developing the Method Selection Guides, ACAORN’s Physical Activity and Sedentary Behaviour Stream aim to assist researchers and practitioners interested in understanding more about the measurement of sedentary behaviours in children and adolescents.

British Heart Foundation Releases Report on Sedentary Behaviour

| June 13, 2012 | 0 Comments

The British Heart Foundation National Centre has just released an evidence briefing focused on sedentary behaviour.  From their website:

The benefits of a physically active lifestyle are well established and reflected in public health guidelines and policy. In recent years there has been growing interest in the role that sedentary behaviour may play in health and wellbeing.

Informed by this emerging body of evidence, public health guidelines now recommend that people of all ages should avoid prolonged periods of sedentary behaviour and break up periods of sitting.

This new BHFNC evidence briefing provides an overview of the evidence relating to sedentary behaviour and public health.

It defines sedentary behaviour and summarises the risks and current levels as well as the implications for policy and practice. It also reviews the evidence for the effectiveness of interventions to reduce sedentary behaviour.

Neville Owen Explains the Health Impact of Sedentary Behaviour

| November 23, 2011 | 4 Comments
Dr Neville Owen is one of the world’s foremost researchers of sedentary behaviour.  Based at the Baker IDI Heart and Diabetes Institute and the University of Queensland, Dr Owen has co-authored several seminal studies, including those linking sedentary behaviour with mortality, and suggesting that breaks in sedentary behaviour may be associated with improved health regardless of total sedentary time.


Last week Dr Owen spoke with researchers at the University of California, San Diego (UCSD), and was kind enough to allow SBRN member Ernesto Ramirez to record and publish two videos of his talk, which are embedded below.  In the first video, you can see Dr Owen explain what sedentary behaviour is, how an “active” person can still accumulate lots of sedentary time, and the impact of interventions aimed at reducing sedentary time.  In the second video, Dr Owen takes questions from the audience on the impact of sedentary behaviour in kids, how we can change the work environment to allow people to reduce their sedentary behaviour, and gives his thoughts on standing desks.

Thanks to Dr Owen for allowing his talk to be recorded and published by SBRN, and thanks to Ernesto Ramirez for the excellent recording.



Sedentary Behaviour Infographic

Earlier this year created an evidence-based infographic summarizing the link between sedentary behaviour and increased health risk.  It’s a very large image so we’ve included the small version below, while the full version can be found here.
