In partnership with six Continuing Care Retirement Communities (CCRCs), the current study focused on the feasibility of recruiting a representative sample of residents and then assessing their functional health.
With our guidance, each of the six CCRCs recruited a volunteer (V-Group) and random (R-Group) sample of independent living residents. We provided face-to-face training and ongoing remote electronic support to the CCRC staff on the testing battery and the Web-based data entry system. The testing battery was consisted of demographic, physical function, and psychosocial assessments.
After training, CCRC staff were receptive to the study goals and successfully used the data entry Website. In the V-Group (N=189), 76% were already participating in CCRC wellness programs. We attempted to recruit a random, unbiased (R-Group) sample of 20% (n=105) of eligible residents; however, only 30 consented to be tested and 70% of this group (21/30) were also already participating in a wellness program. Mean age of all participants was 82.9 years. The V-Group had a higher Short Physical Performance Battery (SPPB) total score (least squares mean [SE], 9.4 [0.2] vs 8.2 [0.4], p=0.014) and SPPB gait speed component score (3.5 [0.1] vs 3.0 [0.2], p=0.007) and spent more time doing moderate-to-vigorous physical activity (300 [21] vs 163 [49] min/week, p=0.013) compared to the R-Group.
While it is feasible to recruit, assess and transmit data on residents' functional health in partnership with CCRCs, population validity was severely compromised. Attention needs to be given to the development of more effective methods to recruit less interested residents.
本研究与六个持续护理退休社区（CCRCs）合作，重点关注招募具有代表性的居民样本并评估其功能健康的可行性。
在我们的指导下，六个CCRCs各自招募了独立生活居民的志愿者样本（V组）和随机样本（R组）。我们就测试组合和基于网络的数据录入系统为CCRCs工作人员提供了面对面培训和持续的远程电子支持。测试组合包括人口统计学、身体功能和社会心理评估。
培训后，CCRCs工作人员接受了研究目标，并成功使用了数据录入网站。在V组（N = 189）中，76%的人已经在参加CCRCs健康计划。我们试图招募符合条件居民的20%（n = 105）的随机、无偏样本（R组）；然而，只有30人同意接受测试，且该组中的70%（21/30）也已经在参加健康计划。所有参与者的平均年龄为82.9岁。与R组相比，V组的简短身体表现测试电池（SPPB）总分更高（最小二乘均值[SE]，9.4 [0.2]对8.2 [0.4]，p = 0.014），SPPB步态速度分量得分更高（3.5 [0.1]对3.0 [0.2]，p = 0.007），且进行中度至剧烈身体活动的时间更多（300 [21]对163 [49]分钟/周，p = 0.013）。
虽然与CCRCs合作招募、评估和传输居民功能健康数据是可行的，但总体有效性受到严重影响。需要关注开发更有效的方法来招募兴趣较低的居民。
