To investigate the efficacy of a community group-based intervention among community-dwelling older adults with physio-cognitive decline syndrome (PCDS).
A prospective cluster randomized controlled trial included 733 community-dwelling older adults with adjusted Montreal Cognitive Assessment (MoCA adj) scores >18 from 40 community-based sites across Taiwan. PCDS was defined as the concomitant presence of physical declines, i.e., slowness and/or weakness plus dysfunction in any cognitive domain. The multidomain intervention integrated physical exercise, cognitive training, nutritional advices and health education lessons. Conventional health education in control group entailed periodic telephone calls to offer participants health education and advice. The primary outcome was the mean differences of MoCA adj total scores and all domains of MoCA adj between baseline and 6- and 12-month follow-up in each group of PCDS, cognitive dysfunction, mobility-type frailty and normal functioning, and the secondary outcomes included the changes of frailty score, handgrip strength, gait speed and physical activity. Intervention effects were analysed using a generalized linear mixed model.
Overall, 18.9% of the study sample had PCDS. Multidomain intervention for 12 months significantly improved cognitive performance in people with PCDS, and those with cognitive dysfunction only. An early benefit on visuo-spatial executive function was seen in older adults with mobility-type frailty. Intervention also improved frailty scores among participants with mobility-type frailty, handgrip strength for participants with PCDS, and gait speed in the normal group.
PCDS is a potentially reversible condition that may prevent subsequent disability and dementia, which deserves further investigation to confirm the long-term effects.
调查针对社区居住的有生理认知衰退综合征（PCDS）的老年人的社区为基础的团体干预的疗效。
一项前瞻性的聚类随机对照试验纳入了 733 名来自台湾 40 个社区场所的社区居住的老年人，其经调整的蒙特利尔认知评估（MoCA adj）评分>18。PCDS 的定义是同时存在身体衰退，即任何认知领域的缓慢和/或虚弱加上功能障碍。多领域干预综合了身体锻炼、认知训练、营养建议和健康教育课程。对照组的常规健康教育包括定期打电话给参与者提供健康教育和建议。主要结果是 PCDS、认知功能障碍、移动型虚弱和正常功能的 MoCA adj 总评分和所有领域的 MoCA adj 平均差异，以及次要结果包括虚弱评分、握力、步态速度和身体活动的变化。使用广义线性混合模型分析干预效果。
总体而言，研究样本的 18.9%有 PCDS。12 个月的多领域干预显著改善了有 PCDS 和认知功能障碍的人的认知表现。在移动型虚弱的老年人中，早期对视空间执行功能有获益。干预还改善了移动型虚弱参与者的虚弱评分、PCDS 参与者的握力以及正常组的步态速度。
PCDS 是一种潜在可逆转的状况，可能预防随后的残疾和痴呆，值得进一步研究以确认其长期效果。
