摘要

目的：本研究调查了社区居住的老年社会衰弱患者的认知活动参与水平与痴呆发生风险之间的关系。研究设计：这项前瞻性队列研究包括2725名60岁及以上无痴呆基线的成年人。主要的结果衡量指标社会脆弱性基于五个方面：独居、比前一年外出次数少、不去拜访朋友、感觉对家人和朋友没用、不能每天和别人交谈。符合上述两个或两个以上标准的参与者被定义为具有社会脆弱性。认知活动按执行频率分为12个项目。将社会脆弱状态和认知活动水平结合起来分为四组。采用Cox比例风险模型分析社交脆弱和认知活动组合与60月龄痴呆发生率的关系。结果与无社交脆弱和认知活动参与度高的组相比，社交脆弱和认知活动参与度低的组患痴呆的风险明显更高。然而，前一组人患痴呆症的风险降低了。研究发现，即使在社交能力薄弱的情况下，高度参与认知活动也能降低患痴呆症的风险。对单独执行可行的认知活动有可能使在社会参与方面遇到挑战的老年人受益。

Cognitive activity levels associated with dementia risk in older adults with social frailty: A longitudinal study

Objectives

This study investigated the association between the level of engagement in cognitive activities and the risk of incident dementia among community-dwelling older adults with social frailty.

Study design

This prospective cohort study included 2725 adults aged 60 or more without dementia at baseline.

Main outcome measures

Social frailty was based on five items: living alone, going out less frequently than in the previous year, not visiting friends, not feeling useful to family and friends, and not conversing with someone every day. Participants meeting two or more of these criteria were defined as having social frailty. Cognitive activities comprised 12 items according to the frequency of implementation. Four groups were created by combining social frailty status and cognitive activity levels. The Cox proportional hazards model was used to analyze the relationship between the combination of social frailty and cognitive activity and the incidence of dementia at 60 months.

Results

Compared with the group without social frailty and with high engagement in cognitive activity, the group with social frailty and low engagement had a significantly higher risk of dementia. However, the former group showed a reduction in the risk of dementia.

Conclusions

High engagement in cognitive activities was found to be associated with a reduced risk of dementia, even in the context of social frailty. Cognitive activities that are feasible for solitary execution have the potential to benefit older adults experiencing challenges with social participation.
