项目摘要

ABSTRACT Hypertension rates among middle-aged non-Hispanic black (NHB) adults are among the highest in the world, which is a significant source of racial disparities in ADRD. In September 2020, two NIH directors recommended safety-net health care providers and patients and scientists co-design novel interventions to alleviate racial and socioeconomic disparities in hypertension. Also in 2020, the Lancet Commission on dementia prevention noted that lifestyle interventions may be particularly efficacious for ADRD prevention in subpopulations with high cardiovascular disease risk. This evidence points to a significant need for behavioral intervention co-design with subpopulations at high cardiovascular risk. Thus, we worked with safety-net primary care providers and NHB patients to iteratively co-design an intervention to support hypertension self-management and Mediterranean-Dash Intervention for Neurodegenerative Delay (MIND) diet and aerobic training (MAT). Due to the co-design process, MAT addresses patient and safety-net provider preferences and thus may be an engaging and sustainable strategy in an externally valid setting for the promotion of MIND diet and aerobic activity in a very high-risk subpopulation. MAT is also likely to be potent as over 50% of CVD among NHB adults has been attributed to poor diet and fitness, which contribute greatly to ADRD disparities. MAT involves our CDC-endorsed hypertension self-management education and support classes followed by home-delivered MIND food ingredients and twice-weekly MIND cooking, nutrition, and aerobic activity via videoconference. This novel intervention has not been evaluated for its effects on cognition. In an early stage randomized controlled trial, we aim to demonstrate feasibility and investigate MAT effects on cognition. We propose to test, in a Stage IB pilot RCT, MAT versus our attention control intervention (AC). We will randomize 128 NHB safety-net primary care patients with high systolic blood pressure (≥140 mm Hg) to 28wks of AC or MAT. Provider-led MAT is 28wks followed by 24wks of self-led MAT. Measures will be at baseline, post-treatment (28 weeks), and follow-up (52 weeks). We will measure feasibility and cognition. We will also explore intervention processes and obtain and store blood samples for possible future analyses. A successful pilot would support a follow-on ADRD prevention trial across safety-net primary care sites with the objectives of ADRD prevention and reduction of ADRD disparities.

抽象的中年非西班牙裔黑人 (NHB) 成年人的高血压发病率位居世界最高之列，这是 ADRD 种族差异的一个重要根源。 2020 年 9 月，两位 NIH 主任推荐。安全网医疗保健提供者、患者和科学家共同设计新颖的干预措施，以缓解种族和同样在 2020 年，《柳叶刀》痴呆症预防委员会指出，高血压的差异也趋于平缓。生活方式干预对于 ADRD 预防特别有效该证据表明非常需要行为干预联合设计。具有高心血管风险的亚人群。因此，我们与安全网初级保健提供者和 NHB 患者合作，反复共同设计一个支持高血压自我管理的干预措施和地中海短跑干预措施神经退行性延迟 (MIND) 饮食和有氧训练 (MAT) 由于共同设计过程，MAT。满足患者和安全网提供者的偏好，因此可能是一项有吸引力且可持续的战略在外部有效的环境中，在非常高风险的情况下促进 MIND 饮食和有氧活动 MAT 也可能很有效，因为 NHB 成年人中超过 50% 的 CVD 归因于该人群。不良的饮食和健康状况，极大地导致了 ADRD 差异。 MAT 包括我们 CDC 认可的高血压自我管理教育和支持课程，然后是送货上门的 MIND 食品配料以及每周两次的 MIND 烹饪、营养和有氧活动这种新颖的干预措施尚未在早期阶段评估其对认知的影响。随机对照试验，我们旨在证明可行性并研究 MAT 对认知的影响。我们建议在 IB 阶段试点随机对照试验中测试 MAT 与我们的注意力控制干预 (AC)。将 128 名患有高收缩压 (≥140 mm Hg) 的 NHB 安全网初级保健患者随机分组至 28 周 AC 或 MAT 为 28 周，随后为 24 周的自我主导 MAT 措施。治疗后（28 周）和随访（52 周）我们还将衡量可行性和认知能力。探索干预过程并获取和存储血液样本以供将来可能的成功分析。试点项目将支持在安全网初级保健场所进行后续 ADRD 预防试验，其目标是 ADRD 预防和减少 ADRD 差异。
