目的：描述首次针对个人、人际和社区对行为改变的影响的退休社区体力活动多水平生态干预方案。设计：采用整群随机对照试验设计，包括两个研究臂：体力活动干预和注意力控制成功老龄化条件。背景：圣地亚哥县16个持续护理退休社区。参与者：320名65岁及以上的老年人参与试验。此外，正在招募同伴领袖来领导一些学习活动，特别是在学习活动停止后继续进行干预。干预：体力活动试验的参与者接受个人、人际和社区干预部分。个人层面的组成部分包括计步器、目标设定和个人电话咨询。人际关系层面的组成部分包括小组教育会议和同伴主导的活动。社区层面的组成部分包括资源审计和列举、量身定制的步行地图和社区改进项目。成功老年组接受个体和群体对成功老龄化主题的关注。测量：主要结果是通过加速度计客观测量的轻到中度的体力活动。其他客观结果包括身体功能、血压、身体健康和认知功能。自评量表包括抑郁症状和与健康相关的生活质量。结果：干预在社区成功实施，遵从率较高。结论：生态模型需要针对多层次模型的干预。以前的研究没有包括每个级别的组成部分，退休社区提供了一个示范环境，以演示如何实施这种干预。(C)2012 Elsevier Inc.保留所有权利。
Objectives: To describe the intervention protocol for the first multilevel ecological intervention for physical activity in retirement communities that addresses individual, interpersonal and community influences on behavior change.Design: A cluster randomized controlled trial design was employed with two study arms: a physical activity intervention and an attention control successful aging condition.Setting: Sixteen continuing care retirement communities in San Diego County.Participants: Three hundred twenty older adults, aged 65 years and older, are being recruited to participate in the trial. In addition, peer leaders are being recruited to lead some study activities, especially to sustain the intervention after study activities ceased.Intervention: Participants in the physical activity trial receive individual, interpersonal and community intervention components. The individual level components include pedometers, goal setting and individual phone counseling. The interpersonal level components include group education sessions and peer-led activities. The community level components include resource audits and enumeration, tailored walking maps, and community improvement projects. The successful aging group receives individual and group attention about successful aging topics.Measurements: The main outcome is light to moderate physical activity, measured objectively by accelerometry. Other objective outcomes included physical functioning, blood pressure, physical fitness, and cognitive functioning. Self report measures include depressive symptoms and health related quality of life.Results: The intervention is being delivered successfully in the communities and compliance rates are high.Conclusion: Ecological Models call for interventions that address multiple levels of the model. Previous studies have not included components at each level and retirement communities provide a model environment to demonstrate how to implement such an intervention. (C) 2012 Elsevier Inc.
