This study aims to investigate the correlation between leisure-time physical activity (LTPA) and cognitive function in older adults.
We conducted an analysis of 2,657 participants (aged ≥60 years) from the cross-sectional National Health and Nutrition Examination Survey (NHANES) spanning 2011-2014. Multiple logistic regression and linear regression analyses were employed to explore the associations between leisure-time physical activity and cognitive function.
Significant correlations were observed between LTPA duration and frequency with Animal Fluency Test (AF) and Digit Symbol Substitution Test (DSST) scores. Engaging in leisure-time physical activity 1-4 times per week was associated with a 33%((OR) 0.67, (CI) 0.48-0.92) reduced risk of memory decline compared to non-active individuals. An inverted U-shaped relationship was observed between LTPA duration and AF/DSST and a U-shaped relationship between LTPA frequency and the risk of memory decline.
Encouraging older adults to participate in leisure activities 3-4 times per week may help protect cognitive function.
本研究旨在探讨老年人闲暇时体力活动（LTPA）与认知功能之间的相关性。
我们对 2011-2014 年全国健康和营养调查（NHANES）中 2657 名（年龄≥60 岁）参与者进行了分析。采用多因素逻辑回归和线性回归分析探讨闲暇时体力活动与认知功能之间的关系。
LTPA 持续时间和频率与动物流畅性测试（AF）和数字符号替代测试（DSST）评分显著相关。与不活动的个体相比，每周进行 1-4 次闲暇时体力活动与记忆减退的风险降低 33%（OR 0.67，（CI）0.48-0.92）相关。LTPA 持续时间与 AF/DSST 呈倒 U 型关系，LTPA 频率与记忆减退风险呈 U 型关系。
鼓励老年人每周进行 3-4 次闲暇活动可能有助于保护认知功能。
