Although the management of patients with rheumatic diseases has evolved substantially over the past 20 to 30 years, lifestyle changes (such as weight reduction, physical activity and medication adherence) remain an important and unmet challenge in improving patient outcomes. The field of behavioural economics considers the many ways that individuals behave irrationally and uses the predictability of these patterns to create opportunities to anticipate and avoid or harness these behaviours to improve patient outcomes. Existing among other motivational approaches, the concepts in behavioural economics have only been applied to health care in the past 10 to 15 years. Although few published examples have applied behavioural economic concepts in the management of patients with rheumatic diseases specifically, these concepts have been applied in other chronic diseases, and such interventions could also be applicable in rheumatology. In this Perspectives article, we introduce six principles in behavioural economics (loss aversion, framing effect, present bias, status quo bias, time inconsistency and social normalization), discuss how these concepts have been addressed in other fields and examine their potential application in rheumatology. Using physical activity as an example, we describe how these concepts could be applied to promote healthy behaviour in patients with inflammatory arthritis.

风湿病中不断变化的健康行为：行为经济学简介。

尽管风湿病患者的管理在过去20到30年中已经有了长足发展，但生活方式的改变（例如减轻体重，进行体育锻炼和坚持用药）仍然是改善患者预后的重要且未得到满足的挑战。行为经济学领域考虑了个人非理性行为的多种方式，并利用这些模式的可预测性来创造机会来预测和避免或利用这些行为来改善患者的预后。除其他动机方法外，行为经济学中的概念仅在过去10到15年中才应用于医疗保健。尽管很少有已发表的实例将行为经济学的概念专门用于风湿病患者的治疗，这些概念已被应用于其他慢性疾病，并且此类干预措施也可应用于风湿病学。在此“观点”文章中，我们介绍了行为经济学的六项原理（规避损失，成帧效应，当前偏见，现状偏见，时间不一致和社会正常化），讨论了这些概念如何在其他领域得到解决，并检验了它们在风湿病学中的潜在应用。以体育锻炼为例，我们描述了如何将这些概念应用于炎症性关节炎患者的健康行为。时间不一致和社会正常化），讨论如何在其他领域解决这些概念，并检查其在风湿病学中的潜在应用。以体育锻炼为例，我们描述了如何将这些概念应用于炎症性关节炎患者的健康行为。时间不一致和社会正常化），讨论如何在其他领域解决这些概念，并检查其在风湿病学中的潜在应用。以体育锻炼为例，我们描述了如何将这些概念应用于炎症性关节炎患者的健康行为。
