前言系统思维在儿童肥胖预防工作的制定、实施和评估中的应用代表了社区预防工作的前沿。我们报告了一种方法，以发展一种面向系统的社区视角来研究肥胖的原因。方法小组模型建立会议在澳大利亚的一个农村社区进行，以解决日益增长的儿童肥胖症问题。利益相关者(n=12)使用系统动力学文献中的脚本构建了一个社区模型，该模型从连接圈发展到因果循环图。参与者开始了这项工作，以确定他们社区内儿童肥胖的原因和影响随着时间的推移而发生的变化。50名社区领导人在一整天的会议上对最初的因果循环图进行了审查和详细阐述。结果这个过程创建了一个因果循环图，代表了社区对肥胖决定因素和原因的看法。因果环图可以分为四个不同的领域：社会影响；快餐和垃圾食品；参与体育运动；以及一般的体育活动。讨论这个因果环图可以为社区主导的预防对策规划提供基础，该预防对策与现有环境和系统的多个层次相结合。
IntroductionApplication of system thinking to the development, implementation and evaluation of childhood obesity prevention efforts represents the cutting edge of community-based prevention. We report on an approach to developing a system oriented community perspective on the causes of obesity.MethodsGroup model building sessions were conducted in a rural Australian community to address increasing childhood obesity. Stakeholders (n = 12) built a community model that progressed from connection circles to causal loop diagrams using scripts from the system dynamics literature. Participants began this work in identifying change over time in causes and effects of childhood obesity within their community. The initial causal loop diagram was then reviewed and elaborated by 50 community leaders over a full day session.ResultsThe process created a causal loop diagram representing community perceptions of determinants and causes of obesity. The causal loop diagram can be broken down into four separate domains; social influences; fast food and junk food; participation in sport; and general physical activity.DiscussionThis causal loop diagram can provide the basis for community led planning of a prevention response that engages with multiple levels of existing settings and systems.
