There is considerable scope to improve the delivery of practices that increase the physical activity of children in centre based childcare services. Few studies have reported the effectiveness of interventions to address this, particularly at a population level. The primary aim of this study was to describe the impact of an intervention to increase the adoption of multiple policies and practices to promote physical activity in centre based childcare services.
A quasi experimental study was conducted in centre based childcare services (n =228) in New South Wales (NSW), Australia and involved a three month intervention to increase the adoption of eight practices within childcare services that have been suggested to promote child physical activity. Intervention strategies to support the adoption of practices included staff training, resources, incentives, follow-up support and performance monitoring and feedback. Randomly selected childcare services in the remainder of NSW acted as a comparison group (n = 164) and did not receive the intervention but may have been exposed to a concurrent NSW government healthy eating and physical activity initiative. Self reported information on physical activity policies, fundamental movement skills sessions, structured physical activity opportunities, staff involvement in active play and provision of verbal prompts to encourage physical activity, small screen recreation opportunities, sedentary time, and staff trained in physical activity were collected by telephone survey with childcare service managers at baseline and 18 months later.
Compared with the comparison area, the study found significantly greater increases in the prevalence of intervention services with a written physical activity policy, with policy referring to placing limits on small screen recreation, and with staff trained in physical activity. In addition, non-significant trends towards a greater increase in the proportion of intervention services conducting daily fundamental movement skill sessions, and such services having a physical activity policy supporting physical activity training for staff were also evident.
The intervention was effective in improving a number of centre based childcare service policies and practices associated with promoting child physical activity. Adoption of a broader range of practices may require more intensive and prolonged intervention support.
在中心基础儿童保育服务中提高儿童身体活动的实践有很大的改进空间。很少有研究报告过干预措施的有效性，特别是在人群层面。本研究的主要目的是描述一项干预措施的影响，该干预措施旨在增加多项政策和实践的采用，以促进中心基础儿童保育服务中的身体活动。
在澳大利亚新南威尔士州（NSW）的中心基础儿童保育服务（n=228）中进行了一项准实验研究，该研究涉及为期三个月的干预措施，以增加儿童保育服务中八项被认为可以促进儿童身体活动的实践的采用。支持实践采用的干预策略包括员工培训、资源、激励、后续支持以及绩效监测和反馈。新南威尔士州其余地区随机选择的儿童保育服务作为对照组（n=164），没有接受干预，但可能接触到新南威尔士州政府同时开展的健康饮食和身体活动倡议。通过电话调查，在基线和 18 个月后，向儿童保育服务经理收集有关身体活动政策、基本运动技能课程、结构化身体活动机会、员工参与积极游戏以及提供鼓励身体活动的口头提示、小屏幕娱乐机会、久坐时间以及接受过身体活动培训的员工的信息。
与对照组相比，研究发现干预服务的采用显著增加，包括有书面身体活动政策、政策涉及限制小屏幕娱乐以及有员工接受过身体活动培训。此外，虽然没有显著趋势表明干预服务开展日常基本运动技能课程的比例增加，但也明显表明此类服务有支持员工身体活动培训的身体活动政策。
干预措施有效地改善了与促进儿童身体活动相关的一些中心基础儿童保育服务政策和实践。采用更广泛的实践可能需要更密集和持久的干预支持。
