世界范围内肥胖症的增加导致了被认为是“正常”或理想体重的变化，特别是在高风险人群中。我们表明，社会规范是理解肥胖流行病的关键，社会影响机制提供了个人肥胖相关行为和人口水平特征之间的必要联系。由于影响机制不能直接观察到，我们展示了如何使用三个复杂的系统工具来获得洞察观察到的流行病学模式：社会网络分析，基于代理的建模和系统动力学建模。然而，模拟和数学建模方法提出了关于接受调查结果的问题，特别是在决策者之间。尽管如此，我们指出了肥胖和其他领域的成功模型，包括NIH资助的儿童肥胖研究国家合作（NCCOR）Envison项目。
The worldwide increase in obesity has led to changes in what is considered “normal” or desirable weight, especially among populations at higher risk. We show that social norms are key to understanding the obesity epidemic, and that social influence mechanisms provide a necessary linkage between individual obesity-related behaviors and population-level characteristics. Because influence mechanisms cannot be directly observed, we show how three complex systems tools may be used to gain insights into observed epidemiologic patterns: social network analysis, agent-based modeling, and systems dynamics modeling. However, simulation and mathematical modeling approaches raise questions regarding acceptance of findings, especially among policy makers. Nevertheless, we point to modeling successes in obesity and other fields, including the NIH-funded National Collaborative on Childhood Obesity Research (NCCOR) Envison project.
