Childhood overweight and obesity tracks into adulthood, increasing the risk of developing future chronic disease. Implementing initiatives promoting healthy eating and physical activity in childcare settings has been identified as a priority to prevent excessive child weight gain. Despite this, few trials have been conducted to assess the effectiveness of interventions to support population-wide implementation of such initiatives. The aim of this study is to assess the effectiveness of a multicomponent intervention in increasing the implementation of healthy eating and physical activity policies and practices by centre-based childcare services.
The study will employ a parallel group randomised controlled trial design. A sample of 128 childcare services in the Hunter region of New South Wales, Australia, will be recruited to participate in the trial. 64 services will be randomly allocated to a 12-month implementation intervention. The remaining 64 services will be allocated to a usual care control group. The intervention will consist of a number of strategies to facilitate childcare service implementation of healthy eating and physical activity policies and practices. Intervention strategies will include implementation support staff, securing executive support, consensus processes, staff training, academic detailing visits, performance monitoring and feedback, tools and resources, and a communications strategy. The primary outcome of the trial will be the prevalence of services implementing all healthy eating and physical activity policies and practices targeted by the intervention. To assess the effectiveness of the intervention, telephone surveys with nominated supervisors and room leaders of childcare services will be conducted at baseline and immediately postintervention.
The study was approved by the Hunter New England Human Research Ethics Committee and the University of Newcastle Human Research Ethics Committee. Study findings will be disseminated widely through peer-reviewed publications and conference presentations.

儿童期超重和肥胖会持续至成年期，增加未来患慢性病的风险。在儿童保育机构实施促进健康饮食和体育活动的举措已被确定为预防儿童体重过度增加的一项优先事项。尽管如此，很少有试验来评估支持此类举措在全人群中实施的干预措施的有效性。本研究的目的是评估一项多成分干预措施在提高中心型儿童保育服务机构实施健康饮食和体育活动政策及实践方面的有效性。
本研究将采用平行组随机对照试验设计。将招募澳大利亚新南威尔士州亨特地区的128家儿童保育服务机构参与试验。64家服务机构将被随机分配到为期12个月的实施干预组。其余64家服务机构将被分配到常规护理对照组。干预措施将包括一系列促进儿童保育服务机构实施健康饮食和体育活动政策及实践的策略。干预策略将包括实施支持人员、获得行政支持、达成共识的过程、员工培训、学术详细访问、绩效监测与反馈、工具和资源以及沟通策略。试验的主要结局将是实施干预措施所针对的所有健康饮食和体育活动政策及实践的服务机构的比例。为评估干预措施的有效性，将在基线期和干预结束后立即对儿童保育服务机构指定的主管和班级负责人进行电话调查。
本研究已获得亨特新英格兰人类研究伦理委员会和纽卡斯尔大学人类研究伦理委员会的批准。研究结果将通过同行评审出版物和会议报告广泛传播。
