目的：老年人的体力活动参与率较低，但对电话中介的支持项目反应积极。项目往往受到对专业人员的依赖的限制。这项研究测试了由专业工作人员和训练有素的志愿者同伴导师提供的基于电话的体力活动建议。设计：2003-2008年间进行为期12个月的随机对照临床试验。从旧金山湾区招募了12名志愿者同伴导师和181名最初不活跃的50岁及以上成年人。参与者被随机分为：(1)由专业工作人员提供的基于电话的体力活动建议，(2)由训练有素的志愿者同行提供的基于电话的体力活动建议，或(3)由工作人员提供的营养电话支持的注意力控制部门。主要观察指标：在基线、6个月和12个月采用老年人社区健康活动模式计划(Champs)问卷评估中等强度或更剧烈的体力活动(MVPA)，并在随机选择的亚样本中进行加速度计验证(Actigraph)。治疗忠诚度通过对干预提供的数量和质量的分析来检验。结果：在6个月和12个月时，两个体力活动组的MVPA显著高于对照组。两种体力活动组在提供干预的数量上具有可比性，但同龄人在干预内容的质量上表现出更多的多样性和全面性。结论：这项研究表明，经过训练的同伴志愿者可以通过电话建议有效地促进体力活动增加。这一结果支持了一种具有良好传播潜力的项目交付模式，适用于各种社区环境。
Objective: Older adults have low rates of physical activity participation, but respond positively to telephone-mediated support programs. Programs are often limited by reliance on professional staff. This study tested telephone-based physical activity advice delivered by professional staff versus trained volunteer peer mentors. Design: A 12-month, randomized, controlled clinical trial was executed from 2003-2008. Twelve volunteer peer mentors and 181 initially inactive adults ages 50 years and older were recruited from the San Francisco Bay Area. Participants were randomized to: (1) telephone-based physical activity advice delivered by professional staff, (2) telephone-based physical activity advice delivered by trained volunteer peers, or (3) an attention-control arm of staff-delivered telephone support for nutrition. Main Outcome Measures: Moderate-intensity or more vigorous physical activity (MVPA) was assessed at baseline, 6, and 12 months with the Community Healthy Activities Model Program for Seniors (CHAMPS) Questionnaire, with accelerometry validation (Actigraph) in a randomly selected subsample. Treatment fidelity was examined through analysis of quantity and quality of intervention delivery. Results: At 6 and 12 months, both physical activity arms significantly increased MVPA relative to the control arm. Both physical activity arms were comparable in quantity of intervention delivery, but peers demonstrated more versatility and comprehensiveness in quality of intervention content. Conclusions: This study demonstrates that trained peer volunteers can effectively promote physical activity increases through telephone-based advice. The results support a program delivery model with good dissemination potential for a variety of community settings.
