系统建模代表了一种创新的方法，在社区层面上解决肥胖症的流行。我们开发了一个基于代理的模型的巴尔的摩市食品环境，使我们能够评估不同的计划和政策的相对影响，单独和组合，以及潜在的意想不到的后果。基于这些经验和文献综述，我们确定了一系列原则、潜在益处和挑战。一些关键原则包括在启动模型开发之前与社区进行早期和多层次的接触，以及与社区利益相关者进行持续接触和测试的重要性。重要的好处包括提高社区利益攸关方对该系统的理解，在实施前测试干预措施，以及确定意外后果。这些模型面临的挑战包括决定最重要但最吝啬的因素，如何以现实但可转移的方式模拟食物来源和食物选择行为，以及确定模型的适当结果和局限性。
Systems modeling represents an innovative approach for addressing the obesity epidemic at the community level. We developed an agent-based model of the Baltimore City food environment that permits us to assess the relative impact of different programs and policies, alone and in combination, and potential unexpected consequences. Based on this experience, and a review of literature, we have identified a set of principles, potential benefits, and challenges. Some of the key principles include the importance of early and multilevel engagement with the community prior to initiating model development and continued engagement and testing with community stakeholders. Important benefits include improving community stakeholder understanding of the system, testing of interventions before implementation, and identification of unexpected consequences. Challenges in these models include deciding on the most important, yet parsimonious factors to consider, how to model food source and food selection behavior in a realistic yet transferable manner, and identifying the appropriate outcomes and limitations of the model.
