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.
背景
我们检验了这样一个假设，即更高水平的社交活动与老年人发生残疾的风险降低有关。
方法
数据来自于 Rush 记忆与衰老项目（Rush Memory and Aging Project）中的老年人，这是一项正在进行的老龄化纵向队列研究。分析仅限于没有临床痴呆且在评估的特定功能领域报告不需要帮助完成任何任务的人。参与者的平均随访时间为 5.1 年（SD=2.5）。社交活动基于 6 项指标（拜访朋友或亲戚；去餐馆、参加体育活动或玩游戏；小组会议；教堂/宗教服务；日间或过夜旅行；无报酬的社区/志愿者工作），在基线时进行评估。每年评估基本日常生活活动的残疾、移动障碍和工具性日常生活活动的残疾。使用比例风险模型，调整年龄、性别和教育程度，来检验社交活动与新发残疾之间的关系。完全调整的模型包括抑郁、血管疾病和危险因素、体重指数、社交网络以及自我报告的身体活动的指标。
结果
在没有基线残疾的 954 人中，在完全调整的模型中，每增加一个单位的社交活动，发生日常生活活动障碍的风险降低 43%（风险比=0.57，95%置信区间=0.46，0.71）。社交活动也与移动障碍（风险比=0.69，95%置信区间=0.54，0.88）和工具性日常生活活动障碍（风险比=0.71，95%置信区间=0.55，0.93）的风险降低相关。
结论
在社区居住的老年人中，社交活动与日常生活活动、移动和工具性日常生活活动的残疾风险降低相关。
