Abstract

Objectives: Physical activity (PA) is positively associated with cognitive health. However, the extent to which this relationship varies across different demographic and health status subgroups remains unclear. Methods: This study involves 2,547 US individuals aged ≥60 from the NHANES cycle to examine the associations between device-based PA levels (average daily PA and Peak-30 in the Monitor Independent Movement Summary unit and performance-based cognitive function (memory, executive function, processing speed, and sustained attention) in different subgroups. Results: Both daily PA and higher-intensity PA (Peak-30) showed overlapping positive associations with cognitive function in older adults. However, the strength of these associations varies across subgroups of older adults who share similar demographic and health profiles. Conclusion: These findings could inform the tailoring of PA interventions to meet the specific needs of different older adult subgroups to optimize cognitive benefits and potentially reduce the risk of cognitive impairment and neurodegenerative diseases.

NHANES 2011-2014中不同老年人群体体力活动与认知功能的差异关联

目的：体力活动（PA）与认知健康呈正相关。然而，这种关系在不同人口和健康状况亚组之间的差异程度仍不清楚。方法：本研究涉及来自NHANES周期的2547名年龄≥60岁的美国个体，以检查不同亚组中基于设备的PA水平（平均每日PA和监测独立运动总结单元的峰值-30）与基于性能的认知功能（记忆、执行功能、处理速度和持续注意力）之间的关系。结果：每日PA和高强度PA （Peak-30）与老年人的认知功能都有重叠的正相关。然而，这些关联的强度在具有相似人口和健康概况的老年人亚组中有所不同。结论：这些发现可以为定制PA干预措施提供信息，以满足不同老年人亚群的特定需求，从而优化认知益处，并可能降低认知功能障碍和神经退行性疾病的风险。

期刊介绍： The Journal of Aging and Health is an interdisciplinary forum for the presentation of research findings and scholarly exchange in the area of aging and health. Manuscripts are sought that deal with social and behavioral factors related to health and aging. Disciplines represented include the behavioral and social sciences, public health, epidemiology, demography, health services research, nursing, social work, medicine, and related disciplines. Although preference is given to manuscripts presenting the findings of original research, review and methodological pieces will also be considered.
