Research is still lacking regarding the question as to how programs to promote healthy ageing should be organized in order to increase acceptance and thus effectiveness. For older adults, ecological factors, such as the physical distance to program sites, might predict participation and retention. Thus, the key aim of this analysis was to examine these factors in a physical activity intervention trial. Adults ( = 8299) aged 65 to 75 years were invited to participate and = 589 participants were randomly assigned to one of two intervention groups with 10 weeks of physical activity home practice and exercise classes or a wait-list control group. Response, participation, and dropout data were compared regarding ecological, individual, and study-related variables. Kaplan-Meier curves and Cox regression models were used to determine predictors of dropout. In total, 405 participants completed the study. Weekly class attendance rates were examined regarding significant weather conditions and holiday periods. The highest rates of nonresponse were observed in districts with very high neighborhood levels of socioeconomic status. In this study, ecological factors did not appear to be significant predictors of dropout, whereas certain individual and study-related variables were predictive. Future studies should consider these factors during program planning to mobilize and keep subjects in the program.
关于促进健康老龄化的项目应该如何组织，以提高接受度从而提高效果，这方面的研究仍然不足。对于老年人来说，生态因素，如与项目地点的物理距离，可能会预测参与度和保留率。因此，本分析的主要目的是在一项体育活动干预试验中检验这些因素。邀请年龄在 65 至 75 岁的成年人参加，=589 名参与者被随机分配到两个干预组中的一个，进行为期 10 周的家庭体育活动练习和锻炼课程，或等待名单对照组。比较了与生态、个体和研究相关的变量的反应、参与和辍学数据。使用 Kaplan-Meier 曲线和 Cox 回归模型来确定辍学的预测因素。共有 405 名参与者完成了这项研究。检查了关于重大天气条件和假期的每周上课出勤率。在邻里社会经济地位水平非常高的地区，观察到的无应答率最高。在这项研究中，生态因素似乎不是辍学的重要预测因素，而某些个体和研究相关的变量是预测因素。未来的研究在规划项目时应考虑这些因素，以动员和留住项目中的参与者。
