本研究目的在探讨社区居家老人户外活动频率与功能障碍的关系。参与者是1872名居住在社区的老年人（65-100岁）。参与者被问及日常生活活动（ADL）状态，以及他们在评估前4周内旅行了多远以及多久前往该地区。我们选择了两个人口统计学变量，五个生理变量，11个原发性疾病或老年综合征，和四个心理社会变量作为可能的混淆因素的ADL限制和相关的户外活动。在调整混杂因素后，多元逻辑回归显示，基本ADL和工具ADL的限制与每周外出少于一次和每周进入社区少于一次密切相关。户外活动的自我效能感低与这些户外活动的限制密切相关。这些结果表明，每周至少一次到附近的户外活动对维持体弱老年人的身体功能是有益的。(C)2009爱思唯尔爱尔兰有限公司保留所有权利。
The purpose of this study was to investigate the relationship between the frequency of going outdoors into the life-space and functional impairment in community-living frail elderly people. Participants were 1872 community-dwelling elderly people (65-100 years). The participants were asked activities of daily living (ADL) status and how far they traveled and how often they traveled to that area in the 4 weeks before the assessment. We selected two demographic variables, five physiological variables, 11 primary diseases or geriatric syndromes, and four psychosocial variables as possible confounding factors of ADL limitations and correlates of going outdoors. After adjusting for the confounders, multiple logistic regression showed that limitations in basic ADL and instrumental ADL were most strongly associated with going outside the home less than once a week and with going into the neighborhood less than once a week, respectively. Low self-efficacy for going outdoors related most strongly to restrictions in these outdoor activities. These results suggest that going outdoors into the neighborhood at least once a week is beneficial for maintaining physical function in frail elderly people. (C) 2009 Elsevier Ireland Ltd.
