|dc.description.abstract||There are concerns that sedentariness among young people has increased and that this may be detrimental to their health. The purpose of this study was to examine the association between sedentary activities, including small-screen recreation (SSR: watching TV/DVDs/videos, recreational computer use) and cardiorespiratory endurance (CRE) in children aged 11-15 years. A cross-sectional representative population survey was taken of New South Wales (Australia) school students in Grades 6, 8, and 10 (N=2150) in 2004. Sedentary activities and SSR were measured by it self-report questionnaire. CRE was determined by the 20-meter multi-stage Shuttle run test. The optimal cut point For time spent on SSR was determined by receiver operating characteristic analysis. Time spent in sedentary activities was inversely associated with CRE among Grade 8 students (p=0.01) and Grade 10 girls (p=0.03). CRE was lower among Grade 8 Students (p<0.001) and Grade 10 girls (p<0.001) who spent >= 2 hours/day on SSR compared with students who spent <2 hours/day. The 2-hour/day cut point for SSR had high sensitivity (boys: 84%, [95% CI=79%, 87%]; girls: 79% [95% CI=74%, 84%]) and low specificity (boys: 28% [95% CI=24%, 32%]; girls: 42% [95% 0=38%, 46%]). Cardiorespiratory endurance did not differ consistently across quintiles of sedentariness and SSR among boys; however, among girls there was it consistent inverse association. If confirmed in prospective studies, these findings have important implications for risk of chronic disease.||en_US|

OPUS (Open Publications of UTS Scholars) is the UTS institutional repository. It showcases the research of UTS staff and postgraduate students to a global audience. For you, as a researcher, OPUS increases the visibility and accessibility of your research by making it openly available regardless of where you choose to publish.
Items in OPUS are enhanced with high quality metadata and seeded to search engines such as Google Scholar as well as being linked to your UTS research profile, increasing discoverability and opportunities for citation of your work and collaboration. In addition, works in OPUS are preserved for long-term access and discovery.
The UTS Open Access Policy requires UTS research outputs to be openly available via OPUS. Depositing your work in OPUS also assists you in complying with ARC, NHMRC and other funder Open Access policies. Providing Open Access to your research outputs through OPUS not only ensures you comply with these important policies, but increases opportunities for other researchers to cite and build upon your work.
OPUS archives UTS research submitted for Higher Education Research Data Collection (HERDC) and Excellence in Research for Australia (ERA). It also stores digital theses and forms of scholarship that do not usually see formal publication.
When you claim (or enter) your research in Symplectic Elements, simply upload a copy of your work which can be made openly available. Symplectic provides information on which version of your work to upload. If you are unsure, please supply a copy of the Accepted Manuscript version. Ensure you check the box to "agree to the OPUS license terms".
Once uploaded, your works are automatically sent to OPUS and placed temporarily in Closed Access until reviewed by UTS Library staff.
Once items are cleared of copyright constraints and/or publisher embargoes, your work is moved to Open Access and made accessible to the public.
