背景：在苏格兰，老年人是体育活动干预的主要目标群体，因为他们中有很大一部分是不活跃的。积极的生活方式对健康的益处是众所周知的，但需要对增加老年人活动的最有效的干预措施进行更多的研究。这项名为“伦敦西区步行者65岁以上”的随机对照试验旨在研究通过初级保健向65岁的成年人提供基于计步器的步行干预的可行性，并确定这一试点的效果。本文讨论了研究的理论基础、方案和招募过程。方法/设计：干预包括为期12周的以计步器为基础的毕业步行计划和体力活动咨询。参与者被随机分为立即干预组(即刻组)或12周等待名单对照组(延迟组)，后者随后接受干预。对于这项研究的先导因素，主要的结果衡量标准是计步器步数。对久坐时间和体力活动(躺/坐、站或走的时间；活动PAL(TM)监测器)、情绪(积极和消极情绪量表)、功能能力(老年人运动效能感量表)、生活质量(简表(36)健康调查第2版)和孤独(加州大学洛杉矶分校孤独量表)的次要结果进行评估。有参与者的焦点小组和与研究团队的半结构化访谈记录了他们的干预经验。这项试验的可行性部分考察了通过初级保健和留住参与者招募人员、对老年人进行干预的适当性以及由执业护士提供干预的情况。讨论：伦敦西区65岁以上的步行者将确定通过初级保健向65岁的苏格兰成年人提供基于计步器的步行干预的可行性和有效性。这项研究还将考察干预对参与者幸福感的影响，并深入了解参与者和研究团队成员对干预的体验。
Background: In Scotland, older adults are a key target group for physical activity intervention due to the large proportion who are inactive. The health benefits of an active lifestyle are well established but more research is required on the most effective interventions to increase activity in older adults. The 'West End Walkers 65+' randomised controlled trial aims to examine the feasibility of delivering a pedometer-based walking intervention to adults aged >= 65 years through a primary care setting and to determine the efficacy of this pilot. The study rationale, protocol and recruitment process are discussed in this paper.Methods/Design: The intervention consisted of a 12-week pedometer-based graduated walking programme and physical activity consultations. Participants were randomised into an immediate intervention group (immediate group) or a 12-week waiting list control group (delayed group) who then received the intervention. For the pilot element of this study, the primary outcome measure was pedometer step counts. Secondary outcome measures of sedentary time and physical activity (time spent lying/sitting, standing or walking; activPAL (TM) monitor), mood (Positive and Negative Affect Schedule), functional ability (Perceived Motor-Efficacy Scale for Older Adults), quality of life (Short-Form (36) Health Survey version 2) and loneliness (UCLA Loneliness Scale) were assessed. Focus groups with participants and semi-structured interviews with the research team captured their experiences of the intervention. The feasibility component of this trial examined recruitment via primary care and retention of participants, appropriateness of the intervention for older adults and the delivery of the intervention by a practice nurse.Discussion: West End Walkers 65+ will determine the feasibility and pilot the efficacy of delivering a pedometer-based walking intervention through primary care to Scottish adults aged >= 65 years. The study will also examine the effect of the intervention on the well-being of participants and gain an insight into both participant and research team member experiences of the intervention.
