尽管体育锻炼对终身健康有益，但体弱多病的老年人通常被排除在提倡更积极生活方式的研究之外。本研究记录了一项多地点研究的招募过程和成本，以确定在虚弱/伤害预防研究中招募老年人的有效策略。在7个地点进行了随机对照临床试验；第8个地点是依从性研究。干预措施反映了以中心和家庭为基础的健康促进计划。地点目标、合格标准、接触和筛选方法从操作手册中获得。招聘结果（筛选人数，合格率，随机筛选比例）从招聘数据确定。网站提供了估计的招聘成本（非人工费用、调查员和工作人员的时间、附加福利），直到签署同意书。这些网站针对不同的人群和样本量。大多数公司修改了招聘方法，以达到他们的招聘目标。大多数网站估计每个随机参与者的招聘成本超过300美元。招聘费用受到以下因素的影响：工作人员花时间缓解对参与者健康的担忧、与家庭成员的必要互动以及安排交通。虚弱和干预强度都不是招募结果的主要预测因子。招募费用与选择标准和目标人群的虚弱状况有关。老年人可以成功地加入有益的健康促进计划，但这往往是具有挑战性的。在规划健康促进研究时，调查人员需要了解他们可能需要筛选的老年人数量以及提高招募成功率的不同策略。
Despite the lifelong health benefits of physical activity, frailer older adults have typically been excluded from studies promoting more active lifestyles. This study documents the recruitment process and costs from a multisite study to identify effective strategies for recruiting older adults in frailty/injury prevention research. Randomized controlled clinical trials were conducted at 7 sites; an 8th site was a compliance study. Interventions reflected center- and home-based health promotion programs. Site objectives, eligibility criteria, and contact and screening methods were obtained from manuals of operation. Recruitment results (number screened, eligibility rates, randomized to screened ratios) were ascertained from recruitment data. Sites furnished estimated recruitment costs (nonlabor expenses, investigator and staff time, fringe benefits) up to signing the consent form. The sites targeted diverse populations and sample sizes. The majority revised recruitment methods to meet their recruitment goals. Most sites estimated costs of recruitment at over $300 per participant randomized. Recruitment costs were affected by staff time spent alleviating concerns about participants' health, essential interactions with family members, and arranging for transportation. Neither frailty nor intervention intensity was found to be a major predictor of recruitment outcomes. Recruitment expense was associated with selection criteria and frailty status of the target population. Older people can be successfully recruited into beneficial health promotion programs, but it is often challenging. In planning health promotion studies, investigators need to be aware of the numbers of older people they may need to screen and different strategies for increasing recruitment success.
