Abstract：
Childhood overweight and obesity is a significant public health issue. A key contributing factor is sugar sweetened beverages (SSBs) consumption. Evidence suggests that secondary school students are frequent consumers of SSBs, with high daily consumption. The promotion of water consumption and provision of chilled water stations can reduce SSBs consumption. The Thirsty Choose Water! study will evaluate the effectiveness of two interventions, a behavioural intervention, Thirsty? Choose Water! behavioural intervention (TCW-BI), that target students through the domains of the health promoting high schools framework, and the second intervention is the installation and promotion of chilled water stations.
This community trial will recruit 60 secondary schools from across three Local Health Districts (LHDs) within New South Wales (NSW). A two-by-two factorial study design will be used to determine the effect of the Thirsty? Choose Water! behavioural intervention (TCW-BI), and the installation of chilled water stations. The recruited secondary schools will be randomised and non-blinded to one of four study arms receiving either the TCW-BI or chilled water stations, both interventions, or neither (control group). Baseline measures will be collected including student self-report surveys which will gather data regarding knowledge, attitudes and consumption of water and SSBs, a school profile and an environmental scan. Student surveys will be repeated post the intervention and at follow-up. Regular water meter readings will determine the water flow from the chilled water stations across the study period.
There is an increasing body of evidence which suggests that decreasing consumption of SSBs can impact positively on childhood overweight and obesity. However, in the Australian context there are limited studies on how this may occur in the secondary school setting. This study will add to this evidence base and establish the effectiveness of TCW-BI and chilled water stations, either alone or combination on increasing water consumption in adolescents. Information about barriers and facilitators to implementation will be documented. Packages to support the implementation of the TCW-BI as a state-wide initiative will be developed.

摘要：
儿童超重和肥胖是一个重要的公共卫生问题。一个关键因素是含糖饮料（SSB）的消费。证据表明，中学生经常使用SSB，日常消费高。促进用水量和提供冷冻水站可以减少SSB的消耗。口渴选择水！研究将评估两种干预措施的有效性，行为干预，口渴？选择水！行为干预（TCW-BI），通过健康促进高中框架的领域针对学生，第二个干预措施是安装和推广冷冻水站。
这项社区试验将从新南威尔士州（NSW）的三个地方卫生局（LHD）招募60所中学。将使用二乘二因子研究设计来确定口渴？选择水！行为干预（TCW-BI）的效果，和冷冻水站的安装。被招募的中学将被随机分配，并且不会对接收TCW-BI或冷冻水站的四个研究小组之一产生影响，两种干预措施，或者都没有（对照组）。将收集基线措施，包括学生自我报告调查，这些调查将收集有关知识的数据，水和SSB的态度和消费，学校简介和环境扫描。学生调查将在干预后和后续行动中重复进行。定期的水表读数将确定整个研究期间来自冷冻水站的水流量。
越来越多的证据表明，减少SSB的消费可以对儿童超重和肥胖产生积极影响。然而,在澳大利亚的背景下，关于中学环境中如何发生这种情况的研究有限。这项研究将增加这一证据基础，并建立TCW-BI和冷冻水站的有效性，单独或组合增加青少年的用水量。将记录有关实施障碍和促进者的信息。将开发支持将TCW-BI作为全州计划实施的软件包。
