目的：检查自我报告的体育锻炼与认知功能之间的关联。设计：前瞻性队列研究的二次数据分析。参与者：基线时认知功能正常的社区老年人。测量：在基线和年度随访时收集有关自我报告的体育锻炼、即时和延迟回忆、画钟测试以及对时间和当前事件的定位的数据。采用广义估计方程法确定体育锻炼与认知功能下降之间的关联。结果：分析共有 4,227 名参与者，其中 58% 为女性，78% 为白人，平均 (SD) 年龄 75.7 (7.1) 岁。进行中高强度运动（比值比 [OR] 置信区间 [CI] = 0.45 [0.20, 0.69]；p< .001）和低强度运动（OR [CI] = 0.62 [0.44, 0.83]）的患者认知能力下降的风险较低。结论：这些结果再次证实了体育锻炼对维持老年人认知功能的积极影响。
Objectives: To examine the association between self-reported physical exercise and cognitive function. Design: Secondary data analysis of a prospective cohort study. Participants: Community-dwelling older adults with normal cognitive function at baseline. Measurements: Data on self-reported physical exercise, immediate and delayed recall, clock drawing test, and orientation to time and current events were collected at baseline and annual follow-up visits. Generalized estimation equation method was used to determine the association between physical exercise and decline in cognitive function. Results: A total of 4,227 participants were included in the analysis, 58% women, 78% White, mean (SD) age 75.7 (7.1) years. The risk of cognitive decline was lower among those who reported moderate-to-high intensity exercise (odds ratio [OR] confidence interval [CI] = 0.45 [0.20, 0.69];p< .001) and low-intensity exercise (OR [CI] = 0.62 [0.44, 0.83]). Conclusion: These results reaffirm the positive impact of physical exercise in maintaining cognitive function among older adults.
