项目摘要

OVERALL: ABSTRACT American Indians/Alaska Natives (AI/ANs) and Native Hawaiians and Pacific Islanders (NHPIs) are increasingly concerned about Alzheimer’s disease and related dementias, as these conditions will soon have a major impact on their communities. Although AI/ANs and NHPIs share a high prevalence of ADRD risk factors, including hypertension and type 2 diabetes, their life expectancies have improved by as much as 30 years over the last 5 decades, resulting in a tripling of their populations’ share of people ages 65+. Unfortunately, the healthcare systems that serve AI/ANs and NHPIs are unprepared for the clinical, social, and economic, burdens associated with ADRD. The Natives Engaged in Alzheimer’s Research Center will be the only P01 to include AI/ANs or Native Hawaiians since the National Institute on Aging started cataloging P01s in 1984. Based at Washington State University, with collaborators at the University of Miami, Brigham Young University, and several other major universities, as well as with AI/AN and NHPI community partners, we will create an innovative program to understand, intervene on, and mitigate ADRD-related health disparities experienced by our priority populations. Our 3 Research Projects will be supported by Administrative, Research Methods, Recruitment and Engagement, and Biospecimen Cores. The Center will also feature a network of 8 Satellite Centers led by Native researchers that encompass areas where 90% of AI/ANs and NHPIs reside. These Satellite Centers will ensure that our work and our dissemination efforts are national in scope and help to create research-ready cohorts. The Center will unite scholars across social, clinical, and behavioral sciences. Notably, 12 AI/AN or NH/PI professionals have committed to participate as Investigators or Consultants. Thus, our Specific Aims are to: 1) In a group- randomized trial, test the effectiveness of a culturally informed provider training and “dementia-friendly clinic” intervention for detection and appropriate management of AI/AN patients with ADRD and mild cognitive impairment in at least 20 urban and rural clinics serving AI/ANs; 2) In a group-randomized controlled trial, test the effectiveness of a Hula intervention for preventing cognitive decline in NHPI elders with subjective cognitive impairments or mild cognitive impairment in the Hawaiian Islands; 3) In an observational study, screen AIs in 2 remote reservation communities for obstructive sleep apnea and cognitive impairment, then conduct a randomized controlled trial to test an intervention to improve adherence to sleep apnea treatment for improving or preserving cognitive function; 4) Genotype DNA from saliva samples, catalog the frequency of genetic markers for ADRD risk, and calculate polygenic risk scores for ADRD using biospecimens from 2,700+ AI/ANs and NHPIs; and 5) Create an innovative P01 to understand, intervene on, and mitigate ADRD disparities in AI/ANs and NHPIs. Our leadership, resources, and experience offer an unprecedented opportunity to address the National Institute on Aging’s research priorities for underrepresented minorities, as articulated in the National Plan to Address Alzheimer's Disease, and to respond directly to its interest in diversifying the scientific workforce.

总体：摘要美洲印第安人/阿拉斯加原住民 (AI/AN) 以及夏威夷原住民和太平洋岛民 (NHPI) 越来越多关注阿尔茨海默病和相关痴呆症，因为这些疾病很快就会产生重大影响尽管 AI/AN 和 NHPI 都存在 ADRD 风险因素，包括高血压和 2 型糖尿病患者的预期寿命在过去 5 年内提高了 30 年之多不幸的是，几十年来，65 岁以上人口的比例增加了两倍。为 AI/AN 和 NHPI 服务的系统没有做好应对相关临床、社会和经济负担的准备参与 ADRD 的本地人将是唯一包含 AI/AN 或的 P01。自 1984 年国家老龄化研究所开始对 P01 进行编目以来，夏威夷原住民就已存在。总部位于华盛顿州立大学，与迈阿密大学、杨百翰大学和其他几所大学合作大学以及 AI/AN 和 NHPI 社区合作伙伴，我们将创建一个创新计划了解、干预和减轻我们的重点人群所经历的与 ADRD 相关的健康差异。我们的 3 个研究项目将得到行政、研究方法、招聘和参与的支持，该中心还将拥有一个由本地研究人员领导的 8 个卫星中心网络。涵盖 90% AI/AN 和 NHPI 所在的地区。这些卫星中心将确保我们的工作。我们的传播工作在全国范围内进行，并有助于创建研究就绪的群体。联合社会、临床和行为科学领域的学者值得注意的是，12 位 AI/AN 或 NH/PI 专业人士已联合起来。致力于作为研究人员或顾问参与，因此，我们的具体目标是： 1) 在一个团体中- 随机试验，测试文化知情的提供者培训和“痴呆症友好诊所”的有效性对患有 ADRD 和轻度认知障碍的 AI/AN 患者进行检测和适当管理的干预措施至少 20 个提供 AI/AN 的城市和农村诊所存在损害； 2) 在一项分组随机对照试验中进行测试；草裙舞干预对预防主观认知 NHPI 老年人认知能力下降的有效性夏威夷群岛的损伤或轻度认知障碍；3) 在一项观察性研究中，筛选以下地区的人工智能： 2个针对阻塞性睡眠呼吸暂停和认知障碍的远程预约社区，然后进行随机对照试验测试一种干预措施，以提高对睡眠呼吸暂停治疗的依从性，以改善睡眠呼吸暂停治疗的效果或保留认知功能；4) 对唾液样本进行 DNA 基因分型，对遗传频率进行分类 ADRD 风险标记，并使用来自 2,700 多个 AI/AN 的生物样本计算 ADRD 的多基因风险评分和 NHPI；以及 5) 创建一个创新的 P01，以了解、干预和减轻 ADRD 差异 AI/AN 和 NHPI 的领导力、资源和经验为解决问题提供了前所未有的机会。国家老龄化研究所针对代表性不足的少数群体的研究重点，如国家计划解决阿尔茨海默病，并直接响应其对科学队伍多样化的兴趣。
