We therefore aim to describe the dietary GI and GL of participants of the 2007 Australian National Children's Nutrition and Physical Activity Survey (2007ANCNPAS), and to identify the main foods contributing to their GL. Children, aged 2–16 years, who provided two 24 h recalls in the 2007ANCNPAS were included. A final dataset of 4184 participants was analysed. GI of each food item was assigned using a previously published method. GL was calculated, and food groups contributing to the GL were described by age group and sex. The weighted mean dietary GI and GL of the participants were 54 (sd 5) and 136 (sd 44), respectively. Among the nutrients examined, Ca had the highest inverse relationship with GI (P < 0·001), while percentage energy from starch was most positively associated with GI. The association between fibre density and GI was modest, and percentage energy from sugar had an inverse relationship with GI. Daily dietary GL contributed by energy-dense and/or nutrient-poor (EDNP) items in subjects aged 14–16 years was more than doubled that of subjects aged 2–3 years. To conclude, Australian children and adolescents were having a high-GI dietary pattern characterised by high-starchy food intake and low Ca intake. A significant proportion of their dietary GL was from EDNP foods.

These associations remained significant after adjustment for SCB consumption and total energy intake. Furthermore, there was a positive trend between baseline Na excretion and the individual change in %BF in the study period (+0·364 increase in %BF/g Na excretion at baseline), which was confirmed after inclusion of SCB consumption or total energy intake. There was no significant association between the change in Na excretion and the concurrent change of either BMI-SDS or %BF in any model.ConclusionsOur results suggest that a high intake of processed salty foods could have a negative impact on body weight status in children and adolescents independently from their consumption of SCB.}}, author = {{Libuda, Lars and Kersting, Mathilde and Alexy, Ute}}, issn = {{1368-9800}}, journal = {{Public Health Nutrition}}, pages = {{433--441}}, title = {{{Consumption of dietary salt measured by urinary sodium excretion and its association with body weight status in healthy children and adolescents}}}, doi = {{10.1017/s1368980011002138}}, year = {{2011}}, } @article{27069, author = {{Alexy, Ute and Cheng, Guo and Libuda, Lars and Hilbig, Annett and Kersting, Mathilde}}, issn = {{0261-5614}}, journal = {{Clinical Nutrition}}, pages = {{78--84}}, title = {{{24h-Sodium excretion and hydration status in children and adolescents - Results of the DONALD Study}}}, doi = {{10.1016/j.clnu.2011.08.014}}, year = {{2011}}, } @article{27076, author = {{Muckelbauer, R. and Libuda, Lars and Clausen, K. and Kersting, M.}}, issn = {{1436-9990}}, journal = {{Bundesgesundheitsblatt - Gesundheitsforschung - Gesundheitsschutz}}, pages = {{339--348}}, title = {{{Ansätze der Übergewichtsprävention durch verbessertes Trinkverhalten im Setting Grundschule}}}, doi = {{10.1007/s00103-010-1224-7}}, year = {{2011}}, } @techreport{2734, author = {{Gries, Thomas and Redlin, Margarete}}, pages = {{24}}, publisher = {{Paderborn University, CIE Center for International Economics}}, title = {{{Trade Openness and Economic Growth: A Panel Causality Analysis}}}, volume = {{2011-06}}, year = {{2011}}, } @article{27466, author = {{Bohl, Benjamin and Kepper, Johannes and Röwenstrunk, Daniel}}, journal = {{DIE TONKUNST}}, number = {{3}}, pages = {{270--276}}, title = {{{Perspektiven Digitaler Musikeditionen aus der Sicht des Edirom-Projekts}}}, volume = {{5}}, year = {{2011}}, } @inbook{27589, author = {{Muckelbauer, R. and Libuda, Lars and Kersting, M.}}, booktitle = {{Developing Children´s Food Products.}}, isbn = {{978-1-84569-431-9 }}, publisher = {{Woodhead Publishing Limited }}, title = {{{Fluids and children’s health. }}}, year = {{2011}}, } @inproceedings{27622, author = {{Nebe, Karsten and Fischer, Holger Gerhard and Klompmaker, Florian and Jung, Helge}}, pages = {{263--273}}, publisher = {{Oldenbourg Wissenschaftsverlag GmbH, M {\ "u} nchen}}, title = {{{Multi-touch, tangible and pen-based interaction in incident planning}}}, year = {{2011}}, } @inproceedings{27623, abstract = {{Kollaboratives Lernen kann im Großen und Ganzen durch verteilte, unterbrochene kooperative Prozesse charakterisiert werden, da die Interaktion mit anderen Lernern und Lehrenden zu verschiedenen Zeiten an verschiedenen Orten stattfindet.
