老年拉丁裔人的认知障碍是一个令人担忧的问题，因为这一人口的快速增长以及他们因慢性病而患痴呆症的风险增加。主要来自对非拉丁裔白人的研究的证据表明，体力活动(PA)可能会减少认知能力的下降。很少有纵向研究包括年长的拉丁裔人，对PA的客观测量，或评估认知领域的神经认知测试。这项纵向研究的目的是探索在平均五年的时间里，PA的变化与拉丁裔老年人认知能力下降之间的关系。基线样本的纳入标准为年龄≥50岁，拉丁裔种族(英语或西班牙语)，无行走障碍，无痴呆症证据，以及芝加哥地址。在174名基线参与者中，59人(33.9%)参与了随访。通过问卷调查和佩戴7天的加速度计测量Pa值。一系列神经认知测试评估了情景记忆、知觉速度和语义记忆。认知功能的变化被一分为二地表示维持和下降。二分类Logistic回归分析结果显示，在控制基线年龄、慢性健康问题、抑郁症状和文化适应的情况下，自我报告轻度PA较少下降的患者维持情景记忆，OR=1.16(95%可信区间1.03~1.32)，而在加速计中-剧烈回合中下降较小的患者维持语义记忆，OR=16.08(95%可信区间1.53~168.89)。这些发现表明，随着年龄的增长，维持PA可能会防止认知能力下降。这项工作可以为未来旨在维持PA以防止认知衰退的干预发展提供信息。
Cognitive impairment in older Latinos is a concerning issue due to the rapid growth of this population and their increased risk for dementia due to chronic disease. Evidence, primarily from studies of non-Latino Whites, suggests that physical activity (PA) may reduce cognitive decline. Few longitudinal studies have included older Latinos, objective measures of PA, or neurocognitive tests that assess domains of cognition. The purpose of this longitudinal study was to explore the relation between changes in PA and cognitive decline in older Latinos over an average of five years. Inclusion criteria for the baseline sample were age ≥50 years, Latino ethnicity (English- or Spanish-speaking), no ambulation disability, no evidence of dementia, and Chicago address. Of the 174 baseline participants, 59 (33.9%) participated at follow-up. PA was measured by questionnaire and accelerometer worn for seven days. A battery of neurocognitive tests assessed episodic memory, perceptual speed, and semantic memory. Change in cognitive function was dichotomized to represent maintenance versus decline. Binary logistic regression results indicated that those who had less decline from baseline to follow-up in self-reported light PA maintained episodic memory, OR = 1.16 (95% CI 1.03 – 1.32), while those who had less decline in accelerometer moderate-vigorous bouts maintained semantic memory, OR = 16.08 (95% CI 1.53 – 168.89), controlling for baseline age, chronic health problems, depressive symptoms, and acculturation. These findings suggest that maintenance of PA with aging may prevent cognitive decline. This work can inform future intervention development that aims to maintain PA in order to prevent cognitive decline.
