An epidemiologic study aiming to develop a strategy for transferring improvement of physical and cognitive performance to prevention of disability in the domain of activity and participation among frail older persons.

根据参与社区活动、身体活动、认知活动和工作来评估老年人的活动领域和功能健康参与情况。大约15%有资格接受身体和认知功能干预的人没有参与该领域的四个要素中的任何一个。在这个领域保持参与的人更有可能有提供社会支持的朋友，矫正后的视力更敏锐，并且经常外出。对身体和认知功能的干预应包括对视力、朋友提供的社会支持以及外出进行身体和/或认知训练的频率的干预。

The domain of activity and participation of functional health of older persons was assessed according to involvement in community activities, physical activity, cognitive activities and jobs. About 15 % of persons who were eligible for interventions on physical and cognitive functions had no involvement in any of the four elements of the domain. Persons who maintained involvement in the domain were more likely to have friends who provided social support, to have visual acuity after correction, and to go out frequently. Interventions on physical and cognitive functions should incorporate interventions on visual acuity, social support provided by friends, and frequency of going out in physical and/or cognitive trainings.
