The purpose of the study was to investigate the relationships between frequency of going outdoors and subsequent functional and psychosocial changes over a 20-month period. Data were collected from community-dwelling 107 frail elders who could walk independently but who still needed some assistance to live on their own. Functional and psychosocial status at baseline and follow-up were compared among three groups defined by the frequency of going outdoors: (1) four or more times a week, (2) one to three times a week and (3) less than once a week. At baseline, elders going outdoors more often were less functionally impaired, more socially active, and less depressed than elders going outdoors less often. There was a significant difference in change over time of activities of daily living (ADLs) (p=0.002) among the three groups, even when controlling for baseline differences, and the scores of those who went outdoors almost daily were least likely to decline. More of those going outdoors four or more times a week at baseline were still living at home at follow-up than those in the other two groups (p=0.048). These results suggest that the frequency of going outdoors can predict changes in ADLs over at least a 20-month period.
该研究的目的是调查在20个月的时间里，外出频率与随后的功能和心理社会变化之间的关系。数据收集自107位居住在社区的体弱老人，他们能够独立行走，但仍需要一些帮助才能独自生活。根据外出频率将三组老人进行比较，比较其基线和随访时的功能和心理社会状况：（1）每周四次或更多次；（2）每周一至三次；（3）每周少于一次。在基线时，与外出频率较低的老人相比，外出频率较高的老人功能受损较轻、社交活动更积极且抑郁程度较低。即使在控制了基线差异之后，三组之间日常生活活动（ADL）随时间的变化仍存在显著差异（p = 0.002），几乎每天都外出的老人的得分下降的可能性最小。在随访时，基线时每周外出四次或更多次的老人中，仍在家居住的人数比其他两组更多（p = 0.048）。这些结果表明，外出频率至少在20个月的时间内可以预测ADL的变化。
