SUMMARY Latinx older adults are at higher risk for developing Alzheimer’s Disease and Related Dementias (ADRD) than White older adults. Despite older Latinx adults having lower rates of physical activity (PA) and a high burden of comorbidities that are associated with ADRD, few studies have targeted this population with theory-based and culturally adapted approaches to reduce risk for ADRD. Building on pilot work by the team, the proposed project would allow us to culturally adapt a theory-based intervention to promote moderate-to-vigorous physical activity (MVPA) for Latinx adults ages 55 to 89 years. In Stage I (R61/Aim 1), we will finalize the recruitment and intervention strategy (including finalizing the target mechanisms of adherence to MVPA, initial cultural adaptation and translation) through meetings with our community advisory board and pilot testing with 10 Latinx adults. In Stage II (R33/Aim 2), we will randomize 130 Latinx adults to receive the 16-week, fully remote De Pié y a Movernos (De Pié) intervention or a control condition. The intervention will target the mechanisms of self-efficacy, PA habit strength, social support, and PA enjoyment using a staircase approach where participants will initially reduce their sitting by moving more to build confidence towards engaging in MVPA. Participants will also receive a Fitbit activity tracker, health coaching contacts, feedback on meeting goals, and will identify a support person. We will determine the effect of the De Pié intervention on activPAL accelerometer-based MVPA minutes/day (primary outcome) and adherence to meeting the MVPA guidelines of 150 minutes per week (secondary outcome). Further, mediation analyses will be conducted to determine the effect of the intervention on mechanisms of adherence (self-efficacy, habit strength, social support, enjoyment) and identify whether these mechanisms explain intervention effects on MVPA minutes/week and adherence to MVPA guidelines. We will explore cognition, acculturation, age and sex as moderators of these associations. Results will help identify important mechanisms of adherence to MVPA and inform culturally adapted, theory- based approaches to prevent ADRD in the Latinx community.

概括 拉丁裔老年人患阿尔茨海默病和相关痴呆症 (ADRD) 的风险高于 尽管拉丁裔老年人的体力活动 (PA) 率较低且负担较高。 与 ADRD 相关的合并症，很少有研究针对这一人群进行基于理论和 基于团队的试点工作，提出了降低 ADRD 风险的适应文化的方法。 该项目将使我们能够在文化上适应基于理论的干预措施，以促进中度至剧烈的身体活动 针对 55 至 89 岁拉丁裔成年人的活动 (MVPA) 在第一阶段（R61/目标 1），我们将完成招募。 和干预策略（包括最终确定遵守 MVPA 的目标机制、初始文化 改编和翻译）通过与我们的社区咨询委员会举行会议以及与 10 在第二阶段 (R33/目标 2)，我们将随机抽取 130 名拉丁裔成年人接受为期 16 周的完全远程治疗。 De Pié y a Movernos (De Pié) 干预或控制条件 干预将针对机制。 使用阶梯法评估自我效能、PA 习惯强度、社会支持和 PA 享受，其中 参与者最初将通过更多活动来减少坐姿，以建立参与 MVPA 的信心。 参与者还将收到 Fitbit 活动追踪器、健康教练联系人、会议目标反馈以及 我们将确定一名支持人员，以确定 De Pié 干预对 activPAL 的影响。 基于加速计的 MVPA 分钟/天（主要结果）以及遵守 MVPA 指南 每周 150 分钟（次要结果）。此外，将进行调解以确定分析。 干预对依从机制的影响（自我效能、习惯强度、社会支持、享受） 并确定这些机制是否可以解释干预对每周 MVPA 分钟数和遵守情况的影响 我们将探讨认知、文化适应、年龄和性别作为这些关联的调节因素。 结果将有助于确定遵守 MVPA 的重要机制，并为适应文化的理论提供信息 在拉丁裔社区中预防 ADRD 的方法。
