"Vascular cognitive impairment'' refers to cognitive impairment caused or associated with vascular risk factors, and encompasses a cognitive spectrum ranging from mild cognitive impairment to dementia. We examined the association of leisure activity participation to risk of developing VCI in the Bronx aging study. Over 21 years, 71 of the 401 participants who were free of dementia or VCI at entry developed VCI (49 participants with VCI without dementia). We derived Cognitive and Physical Activity Scales based on frequency of leisure activity participation. A 1-point increase on the Cognitive, but not Physical Activity Scale, was associated with lower risk of VCI (hazard ratio 0.931, 95% confidence interval [CI] 0.895-0.970) in Cox analysis. Participation in cognitive but not physical leisure activities is associated with lower risk of VCI with or without dementia. Prospective studies and clinical trials are needed to define the causal role of cognitive leisure activities in influencing vascular risk for cognitive decline.
“血管性认知障碍”指由血管危险因素引起或与之相关的认知障碍,涵盖从轻度认知障碍到痴呆的一系列认知情况。在布朗克斯衰老研究中,我们研究了休闲活动参与情况与发生血管性认知障碍风险之间的关联。在21年的时间里,401名入组时无痴呆或血管性认知障碍的参与者中有71人患上了血管性认知障碍(49名参与者患有无痴呆的血管性认知障碍)。我们根据休闲活动参与频率得出了认知和身体活动量表。在Cox分析中,认知活动量表上增加1分与血管性认知障碍风险降低相关(风险比0.931,95%置信区间[CI] 0.895 - 0.970),而身体活动量表则不然。参与认知性而非身体性休闲活动与患或未患痴呆的血管性认知障碍风险降低相关。需要进行前瞻性研究和临床试验来确定认知性休闲活动在影响认知衰退血管风险方面的因果作用。
