Childhood obesity is a concern in Australia and across the world. Community-based weight management programs are an important response to address childhood obesity. However, the scientific literature suggests that their effectiveness could potentially be enhanced by providing a structured incentive scheme. This proposal aims to determine the effectiveness of enhanced goal setting linked to a structured incentive scheme designed to improve the sustained health and wellbeing of overweight/obese children within the context of an existing community-based program.
METHODS/DESIGN: This study is a cluster randomized controlled trial delivered within the context of the existing NSW "Go4Fun" program with a 10-week and 6- and 12-month follow-up (n = 40 sites, 570 participants) that compares the effectiveness of small changes to the program in which children were asked to set goals (supported by text messages) and were given rewards for achieving them (intervention). This will be compared to the standard/existing program (control), which did not have the same structured incentive program. Data will be collected for all participants at baseline, end of program, and at 6 and 12 months. The primary outcome is a mean change in body mass index (BMI) z score at the 12-month follow-up. Secondary outcomes include anthropometric measures (body weight, height, and waist circumference) and behavioral measures collected via validated questionnaires. A process evaluation (comprising surveys and focus groups) to determine acceptability and sustainability and to inform downstream translation will also be conducted.
This study will inform policy and program delivery as well as the broader evidence base regarding goal achievement and incentive schemes directed at children's health-related behaviors and will provide evidence that is likely to be transferrable across a range of health conditions.

儿童肥胖问题在澳大利亚乃至全球都备受关注。基于社区的体重管理项目是应对儿童肥胖问题的重要举措。然而，科学文献表明，通过提供结构化激励机制，其效果可能会得到进一步提升。本提案旨在确定在现有基于社区的项目背景下，与结构化激励机制相关的强化目标设定对改善超重/肥胖儿童持续健康和福祉的有效性。
方法/设计：本研究是一项整群随机对照试验，在新南威尔士州现有的“Go4Fun”项目背景下开展，为期10周，并进行6个月和12个月的随访（n = 40个地点，570名参与者）。该试验比较了对项目进行微小调整后的效果，调整内容包括要求儿童设定目标（通过短信提供支持）并为实现目标给予奖励（干预组）。这将与未采用相同结构化激励项目的标准/现有项目（对照组）进行比较。将在基线、项目结束时以及6个月和12个月时收集所有参与者的数据。主要结局是12个月随访时体重指数（BMI）z评分的平均变化。次要结局包括人体测量指标（体重、身高和腰围）以及通过经过验证的问卷收集的行为指标。还将进行一项过程评估（包括调查和焦点小组），以确定可接受性和可持续性，并为后续转化提供信息。
本研究将为政策和项目实施以及关于针对儿童健康相关行为的目标达成和激励机制的更广泛证据基础提供参考，并将提供可能适用于一系列健康状况的证据。
