PROJECT SUMMARY/ABSTRACT Low-income older adults (LIOA) are a population at higher risk to develop Alzheimer's disease and related dementias (ADRD) and sleep disturbances. Although empirical research suggests that physical activity interventions benefit cognition and sleep in older adults in general, the possible benefit of physical activity is understudied in LIOA. The available evidence in LIOA suggests that LIOA experience unique barriers to physical activity, more prevalent physical inactivity and sedentary behaviors. Since physical inactivity and sedentary behaviors are independent risk factors that have synergistic harmful effects for cognitive function and sleep, it is crucial to address them simultaneously to promote cognitive and sleep health in LIOA. The growing wearable device and mobile Health (mHealth) provide an innovative approach to deliver individually tailored physical activity interventions at home with flexible schedules to overcome barriers to physical activity in LIOA. In addition, limited research has examined if physical activity interventions impact the individual’s Amyloid/Tau/ Neurodegeneration (ATN) Alzheimer's disease biological state and whether physical activity may promote cognition through impacting sleep and AD pathology. This randomized controlled trial is designed to examine the immediate and sustaining efficacy of an mHealth-facilitated Physical Activity Toward Health (mPATH) intervention on cognitive function and sleep in LIOA. mPATH is a personalized physical activity intervention that includes personalized physical activity plans and training sessions, exercise at home by following personalized exercise videos, and biweekly phone coaching over 24 weeks, supported by wearable devices-enabled mHealth strategies. mHealth strategies and exercise videos will be used to support participant’s physical activity during 6-12months. In the proposed study, we will randomize 176 community dwelling LIOA with insomnia symptoms and without dementia to the mPATH or control group on a 1:1 ratio. Randomization will be stratified by age, sex, and cognitive status. Specifically, we will (1) test the immediate (6- month) and sustaining (12-month) effects of mPATH on cognitive function among LIOA, compared to control; (2) test the immediate (6-month) and sustaining (12-month) effects of mPATH on sleep, compared to control; and (3) explore the effect of mPATH on ATN biomarkers and potential mediating roles of sleep and ATN biomarkers in mPATH’s effect on episodic memory.

项目总结/摘要 低收入老年人（LIOA）是患阿尔茨海默病及相关疾病的风险较高的人群。 痴呆症（ADRD）和睡眠障碍。尽管实证研究表明， 一般来说，干预措施有益于老年人的认知和睡眠，身体活动的可能益处是 在LIOA学习。LIOA中的现有证据表明，LIOA经历了独特的障碍， 身体活动，更普遍的身体不活动和久坐行为。由于缺乏体力活动， 久坐行为是对认知功能有协同有害影响的独立危险因素 和睡眠，同时解决这些问题以促进LIOA的认知和睡眠健康至关重要。的 不断增长的可穿戴设备和移动的健康（mHealth）提供了一种创新的方法， 通过灵活的时间表在家中进行量身定制的身体活动干预，以克服身体活动的障碍 在LIOA。此外，有限的研究已经检查了身体活动干预是否会影响个人的健康。 淀粉样蛋白/Tau/神经变性（ATN）阿尔茨海默病的生物学状态和体力活动是否可能 通过影响睡眠和AD病理来促进认知。本随机对照试验旨在 检查mHealth促进身体活动对健康的直接和持续功效 （mPATH）干预对LIOA患者认知功能和睡眠的影响。mPATH是一种个性化的体力活动 干预，包括个性化的身体活动计划和训练课程，在家锻炼， 在可穿戴设备的支持下， 移动医疗战略。移动健康策略和运动视频将用于支持 参与者在6- 12个月期间的身体活动。在拟议的研究中，我们将随机抽取176个社区， 将有失眠症状且无痴呆的居住LIOA与mPATH或对照组以1：1的比例进行比较。 随机化将按年龄、性别和认知状态分层。具体来说，我们将（1）测试即时（6- 与对照组相比，mPATH对LIOA患者认知功能的影响持续（12个月）; (2)与对照组相比，测试mPATH对睡眠的即时（6个月）和持续（12个月）影响; 探讨mPATH对ATN生物标志物的影响以及睡眠和ATN的潜在介导作用 mPATH对情景记忆影响的生物标志物。
