摘要

目的:研究表明,体育锻炼(PA)可以改善各个领域的认知功能。然而,包括步数在内的不同体力活动测量方法的具体作用仍有待探索。我们的目的是评估客观测量的 PA 与认知功能之间的相关性:我们从瑞典 SNAC-K 研究(2016-2019 年)中纳入了 663 名年龄≥66 岁的成年人。通过有效测试评估了总体认知和三个认知领域(处理速度、执行功能和外显记忆)。PA 通过 ActivPAL3 加速计进行测量。我们采用了年龄分层法(结果:每增加 1000 步(β = 0.04;95% CI:0.01, 0.07)和每天增加一小时 MVPA(β = 0.28;95% CI:0.02, 0.54)对最年轻的老年人来说与更好的处理速度相关,但对最年长的老年人来说则不相关。如果根据 MVPA 进一步分层(结论:我们的研究将加速度计评估的运动量与处理速度联系起来:我们的研究将加速度计评估的 PA(步数和 MVPA)与最年轻的成年人更好的处理速度联系起来。无论运动强度如何,步数都与处理速度相关。需要进一步研究来确定这些关联的方向性。

Association Between Accelerometer-Assessed Physical Activity and Cognitive Function in Older Adults: A Cross-Sectional Study.

Objective: Research suggests that physical activity (PA) improves cognitive function across various domains. However, the specific role of different PA measures, including step count, remains to be explored. Our aim was to assess the correlation between objectively measured PA and cognitive function.

Methods: We included 663 adults, aged ≥66 years, from the Swedish SNAC-K study (2016-2019). Global cognition and three cognitive domains (processing speed, executive function, and episodic memory) were assessed with validated tests. PA was measured through ActivPAL3 accelerometers. We applied age-stratified (<70 vs. ≥80 years), multi-adjusted, quantile regression to examine the cross-sectional associations between cognitive function and PA, considering steps/day and time spent in moderate-to-vigorous PA (MVPA).

Results: Each 1000-step increment (β = 0.04; 95% CI: 0.01, 0.07) and each additional hour of MVPA per day (β = 0.28; 95% CI: 0.02, 0.54) were correlated with better processing speed in the youngest-old, but not in the oldest-old. When further stratifying by MVPA (<60 min vs. ≥60 min/week), each 1000-step increment was associated with better processing speed in the youngest-old, regardless of their MVPA levels.

Conclusion: Our study links accelerometer-assessed PA (steps and MVPA) with better processing speed in the youngest-old adults. Step count correlated with processing speed regardless of intensity. Further research is needed to determine the directionality of these associations.

期刊介绍: The American Journal of Geriatric Psychiatry is the leading source of information in the rapidly evolving field of geriatric psychiatry. This esteemed journal features peer-reviewed articles covering topics such as the diagnosis and classification of psychiatric disorders in older adults, epidemiological and biological correlates of mental health in the elderly, and psychopharmacology and other somatic treatments. Published twelve times a year, the journal serves as an authoritative resource for professionals in the field.
