This study investigated the relationship between the frequency of going outdoors among ambulatory frail elders living at home and subsequent functional and psychosocial changes.
In this 9-month prospective cohort study, data were collected via questionnaire from 112 frail elderly persons living at home and their families. Functional and psychosocial status at baseline and follow-up regarding activities of daily living, functional capacity, depression, self-efficacy for daily activities, self-efficacy for health promotion, and social support, were compared among 3 groups defined by the frequency of going outdoors: 1) more than 4 times a week, 2) 1-3 times a week, 3) less than once a week. At baseline, elders going outdoors more often were less functionally impaired, more socially active, and scored less depressed than elders going outdoors less often.
There were significant differences in functional capacity (p=.0201) and intellectual activities (p=.0026) over time according to the frequency of going outdoors, even when controlling for baseline differences, and the scores of those who seldom went outdoors decreased rapidly. There were similar relationships between frequency of going outdoors and changes in self-efficacy for both daily activities (p=.0067) and for health promotion (p=.0245), with participants going outdoors most frequently improving significantly more.
These results suggest that the frequency of going outdoors may be a useful and simple indicator to predict changes in functional capacity, intellectual activity and self-efficacy.
本研究调查了居家生活的体弱老年人外出频率与随后的功能及心理社会变化之间的关系。
在这项为期9个月的前瞻性队列研究中,通过问卷收集了112名居家体弱老年人及其家人的数据。比较了按外出频率划分的3组人群在基线和随访时的功能及心理社会状况,包括日常生活活动、功能能力、抑郁、日常活动自我效能感、健康促进自我效能感和社会支持:1)每周超过4次,2)每周1 - 3次,3)每周少于1次。在基线时,外出更频繁的老年人功能受损程度更低,社交更活跃,且抑郁得分低于外出较少的老年人。
即使在控制基线差异后,根据外出频率,随着时间推移,功能能力(p = 0.0201)和智力活动(p = 0.0026)仍存在显著差异,很少外出的老年人得分下降迅速。外出频率与日常活动自我效能感(p = 0.0067)和健康促进自我效能感(p = 0.0245)的变化之间也存在类似关系,外出最频繁的参与者改善更为显著。
这些结果表明,外出频率可能是预测功能能力、智力活动和自我效能感变化的一个有用且简单的指标。
