DESCRIPTION (provided by applicant): Osteoarthritis (OA) is the most common condition affecting older people today. It is the leading cause of disability among older people and its impact is projected to increase substantially with the aging of the U.S population (CDC, 1999; CDC, 2003). To date, 10 randomized trials of exercise interventions have been conducted among persons with OA. Although most report positive short-term outcomes at three months or less, only two have reported mixed findings on longer-term adherence and related outcomes at 12 or 18 months. This paucity of data on the maintenance of long-term exercise behavior among persons with OA indicates an urgent need for additional studies of issue. This study will use a multi-site randomized controlled trial with repeated measures to assess the comparative effects of two different ways of enhancing tong-term adherence to and benefits associated with participation in the evidence-based, Fit and Strong multi-component exercise intervention for older persons with lower extremity OA (Hughes et al., in press). We will recruit 600 persons to participate in the 8-week Fit and Strong program. At the conclusion of Fit and Strong, participants will be stratified by arthritis severity and randomized to either Negotiated Maintenance, in which individualized tailored adherence plans will be developed, or Mainstreamed Maintenance, in which participants will be mainstreamed into an ongoing facility-based program at each of four participating study sites. In addition, half of the participants in both maintenance arms will be randomly assigned to receive telephone reinforcement. We will use generalized estimating equations and random effects models to test the hypotheses that Negotiated maintenance participants will experience significantly greater levels of adherence to exercise at 2, 6, 12, 18, and 24 months, and significant improvements in self-efficacy for exercise, self-efficacy for exercise adherence, self reported and observed functional status, and psychosocial measures compared to Mainstreamed maintenance participants at 2, 6, 12, and 18 months.

描述（由申请人提供）：骨关节炎（OA）是当今影响老年人的最常见疾病。它是导致老年人残疾的主要原因，预计其影响将随着美国人口的老龄化而大幅增加（CDC, 1999； CDC, 2003）。迄今为止，在OA患者中进行了10项运动干预的随机试验。虽然大多数报告在3个月或更短的时间内取得了积极的短期结果，但只有两家报告了在12或18个月的长期依从性和相关结果方面的混合结果。骨性关节炎患者维持长期运动行为的数据缺乏表明迫切需要对此问题进行进一步的研究。本研究将采用一项多地点随机对照试验，采用重复测量来评估两种不同方法的比较效果，以增强长期坚持和参与基于证据的Fit和Strong多组分运动干预对老年下肢OA患者的益处（Hughes等人，出版中）。我们将招募600人参加为期8周的Fit and Strong项目。在Fit and Strong结束时，参与者将根据关节炎严重程度进行分层，并随机分配到协商维持组（协商维持组将制定个性化的依从性计划）或主流维持组（主流维持组），参与者将在四个参与研究地点的每个地点纳入正在进行的基于设施的计划。此外，两个维修组的一半参与者将被随机分配接受电话强化。我们将使用广义估计方程和随机效应模型来检验假设：与主流维持参与者相比，协商维持参与者在2、6、12、18和24个月时对运动的坚持程度显著提高，在运动自我效能、运动坚持的自我效能、自我报告和观察的功能状态和心理社会测量方面显著改善。
