背景资料。我们测试了这一假设，即较高的社会活动水平与老年人发生残疾的风险降低相关。数据来自正在进行的纵向队列Rush Memory and Aging Project中的老年人。衰老的研究。分析仅限于没有临床痴呆症的人，并报告在评估的特定功能领域不需要帮助执行任何任务。参与者被跟踪调查的平均时间为5.1年(SD=2.5)。根据6个项目(拜访朋友或亲戚；去餐馆、体育赛事或玩游戏；小组会议；教堂/宗教服务；日间或过夜旅行；无偿社区/志愿者工作)对社会活动进行基线评估。每年评估日常生活基本活动能力障碍、行动能力障碍和日常生活工具活动能力障碍。根据年龄、性别和教育程度进行调整的比例风险模型被用来检验社会活动和意外残疾之间的关联。完全调整的模型包括抑郁、血管疾病和危险因素的术语、体重指数、社会网络和自我报告的体力活动。在完全调整的模型中，在954名没有基线残疾的人中，每增加一个社会活动单位，日常生活活动中发生残疾的风险降低43%(危险比=0.57，95%可信区间=0.46，0.71)。社会活动还与活动障碍(危险比=0.69，95%可信区间=0.54，0.88)和日常生活工具性活动障碍(危险比=0.71，95%可信区间=0.55，0.93)的风险降低有关。在社区居住的老年人中，社会活动与日常生活活动、行动能力和工具性活动中的意外残疾风险降低有关。
Background. We tested the hypothesis that a higher level of social activity was associated with decreased risk of incident disability in older adults.Methods. Data came from older adults in the Rush Memory and Aging Project, an ongoing longitudinal cohort. study of aging. Analyses were restricted to persons without clinical dementia and reporting no need for help performing any task in the particular functional domain assessed. Participants were followed for an average of 5.1 years (SD = 2.5). Social activity, based on 6 items (visiting friends or relatives; going to restaurants, sporting events, or playing games; group meetings; church/religious services; day or overnight trips; unpaid community/volunteer work), was assessed at baseline. Disability in basic activities of daily living, mobility disability, and instrumental activities of daily living was assessed annually. Proportional hazard models adjusted for age, sex, and education were used to examine the association between social activity and incident disability. Fully adjusted models included terms for depression, vascular diseases and risk factors, body mass index, social networks, and self-reported physical activity.Results. In fully adjusted models, among 954 persons without baseline disability, the risk of developing disability in activities of daily living decreased by 43% (hazard ratio = 0.57, 95% confidence interval = 0.46, 0.71) for each additional unit of social activity. Social activity was also associated with decreased risk of developing mobility disability (hazard ratio = 0.69, 95% confidence interval = 0.54, 0.88) and disability in instrumental activities of daily living (hazard ratio = 0.71, 95% confidence interval = 0.55, 0.93).Conclusions. Social activity is associated with a decreased risk of incident disability in activities of daily living, mobility, and instrumental activities of daily living, among community-dwelling older adults.
