People with rheumatoid arthritis are at greater risk of morbidity and mortality from cardiovascular disease than the general population. Sustained physical activity increases cardio-respiratory fitness and reduces cardiovascular disease risk factors. However, little is known about how we can effectively promote long-term participation in physical activity in patients with rheumatoid arthritis. The literature consistently calls for physical activity interventions, and their implementation, to be theoretically-grounded.
METHODS/DESIGN: This paper documents the protocol of a randomised control trial that investigates whether a Self-determination Theory-based intervention fosters the adoption and maintenance of physical activity (3, 6 and 12 months) sufficient to provide sustained cardiovascular and personal well-being benefits in patients with rheumatoid arthritis. The cost effectiveness of the intervention will also be determined. The trial is registered as Current Controlled Trials ISRCTN04121489.
Results from this trial will provide guidance regarding key social environmental factors that can be manipulated to support motivational processes conducive to positive health behaviour change and optimal functioning in patients with Rheumatoid Arthritis.
类风湿性关节炎患者患心血管疾病的发病和死亡风险高于普通人群。持续的体育活动可提高心肺功能，并降低心血管疾病风险因素。然而，对于如何有效促进类风湿性关节炎患者长期参与体育活动，我们知之甚少。文献一直呼吁体育活动干预及其实施要有理论依据。
方法/设计：本文记录了一项随机对照试验的方案，该试验调查基于自我决定理论的干预措施是否能促进类风湿性关节炎患者采用并维持体育活动（3个月、6个月和12个月），从而为其提供持续的心血管和个人幸福感益处。还将确定该干预措施的成本效益。该试验已在“当前对照试验”注册，注册号为ISRCTN04121489。
该试验结果将为关键社会环境因素提供指导，这些因素可被操控以支持有利于类风湿性关节炎患者积极健康行为改变和最佳功能的动机过程。
