目的：采用等时间替代模型，研究以体力活动代替久坐时间对社区老年人认知功能的影响。方法本横断面研究纳入了东京荒川区居民，他们是Arakawa 85+研究的前瞻性队列的一部分。我们用三轴活动记录仪测量了136名参与者的身体活动。使用Addenbrooke's Cognitive Examination‐III测量认知功能，并将参与者分为“认知衰退组”（Addenbrooke's Cognitive Examination‐III≤88）和“认知维持组”（Addenbrooke's Cognitive Examination‐III≥89）。身体活动分为三类：久坐行为（≤1.5代谢当量）、轻度身体活动（1.5至<3.0代谢当量）和中度至剧烈身体活动（≥3代谢当量）。使用等时间替代方法，我们应用多元逻辑回归分析来证明认知功能与用同等时间的轻体力活动代替30分钟/天的久坐行为之间的关联。协变量包括年龄、教育程度和流行病学研究中心抑郁量表。结果：我们的研究结果表明，在男性中，每天用轻度体育活动取代30分钟的久坐行为，维持认知功能的几率增加1.47倍。在女性参与者中没有观察到体育活动和认知功能之间的联系。结论以轻体力活动替代久坐行为有助于维持社区老年老年人的认知功能。这些结果强调了行为改变对促进认知的重要性。Geriatr Gerontol Int 2020；20: 773 - 778。
AimTo investigate the influence of replacing sedentary time with physical activity on cognitive function using an isotemporal substitution model in a population of community‐dwelling oldest old.MethodsThis cross‐sectional study included residents of the Arakawa ward, Tokyo, who were part of a prospective cohort from the Arakawa 85+ study. We measured physical activity in 136 participants using a triaxial actigraph. Cognitive function was measured using the Addenbrooke's Cognitive Examination‐III and participants were divided into a “cognitive decline group” (Addenbrooke's Cognitive Examination‐III ≤88) and “cognitive maintain group” (Addenbrooke's Cognitive Examination‐III ≥89). Physical activity was divided into three categories: sedentary behavior (≤1.5 metabolic equivalents), light physical activity (>1.5 to <3.0 metabolic equivalents), and moderate‐to‐vigorous physical activity (≥3 metabolic equivalents). Using an isotemporal substitution approach, we applied multiple logistic regression analysis to demonstrate the association between cognitive function and replacing 30 min/day of sedentary behavior with an equal period of light physical activity. Covariates included age, education and the Center for Epidemiologic Studies Depression Scale.ResultsOur findings showed that in men, replacing 30 min of sedentary behavior per day with light physical activity was associated with a 1.47‐fold increase in the odds of maintaining cognitive function. An association between physical activity and cognitive function was not observed in female participants.ConclusionsOur results indicate that substituting sedentary behavior with light physical activity could be helpful in maintaining cognitive function in community‐dwelling oldest old men. These results highlight the importance of behavioral changes to promote cognition.Geriatr Gerontol Int 2020; 20: 773–778.
