项目摘要
ABSTRACT
Alzheimer’s disease and related dementias (ADRD) affects over 5.7 million Americans and over 35 million people
worldwide. Indigenous populations including American Indians, Alaskan Natives, Native Hawaiians and Pacific
Islanders are increasingly concerned about ADRD and its prodromal state, mild cognitive impairment (MCI), as
these conditions increasingly exert a major impact on their communities. Although these populations are culturally
diverse and geographically dispersed, they share in common a high prevalence of well-established ADRD risk
factors. Life expectancies in indigenous populations have increased over the past 5 decades resulting in a 3-fold
increase in people over the age of 65. These changing demographics have made ADRD potentially more visible to
communities, however the healthcare systems that serve these populations are unprepared for the patient,
caregiver, social, and economic burdens associated with ADRD. Unfortunately, these same communities have low
health literacy and limited research readiness needed to address the growing problem of ADRD. Situated in the
heart of the South Pacific, American Samoa is the only U.S. territory located south of the equator. The 2020 U.S.
Census recorded 49,710 residents, with 11,025 (4.1%) of the population over age 50. Currently, there are no known
studies that document ADRD prevalence within the Samoan population. Our overarching OBJECTIVE is to build
upon our prior work, test novel approaches to increase ADRD literacy and research readiness, improve detection
of ADRD, and build upon a nascent research infrastructure to conduct important phenotypic and genotypic
characterization of ADRD in American Samoa. Our SPECIFIC AIMS are: (1) Test ADRD knowledge, health
literacy, research readiness and determine ADRD resilience and vulnerability factors, and cognitive status in a
probability sample of 981 Samoans age 50+ using culturally adapted instruments in our probability sample, (2)
Conduct Gold Standard evaluations in our probability sample using the Uniform Data Set (UDSv3.0) from the NIA
Alzheimer’s Disease Research Center program to determine a population-based prevalence of MCI and ADRD for
harmonization, data sharing, and comparison to other groups, and (3) Cross-validate Gold Standard dementia
evaluations with genetic (i.e., ApoE) and plasma Amyloid-Tau-Neuronal Injury/Neurodegeneration (ATN)
framework (e.g., A 40, A42, p-tau, NFL, GFAP) biomarkers in our probability sample and compare to
information available for other racial/ethnic groups.
The dearth of relevant clinical and programmatic knowledge hamstrings efforts by clinicians, scientists,
policymakers, and communities to reduce ADRD disparities in American Samoa. Our short-term goal is to
determine ADRD prevalence and study resilience and vulnerability factors contributing to ADRD in American
Samoa and share resources with other investigators. Our long-term goal is foster future research efforts to
increase accurate and early diagnosis, expand access to care, and improve health outcomes in American Samoa.
摘要
阿尔茨海默病和相关痴呆症(ADRD)影响着超过570万美国人和超过3500万人
全世界。土著人口,包括美洲印第安人、阿拉斯加原住民、夏威夷原住民和太平洋人
岛民越来越关注ADRD及其前驱状态--轻度认知障碍(MCI),因为
这些情况日益对他们的社区产生重大影响。尽管这些人口在文化上
它们具有多样性和地理上的分散性,共同具有公认的ADRD风险的高患病率
各种因素。在过去的50年里,土著人口的预期寿命增加了3倍
65岁以上的人口增加。这些不断变化的人口统计数据使ADRD潜在地更容易为
社区,然而,为这些人群服务的医疗系统对患者毫无准备,
与ADRD相关的照顾者、社会和经济负担。不幸的是,这些社区的
需要健康素养和有限的研究准备来解决日益严重的ADRD问题。位于
美属萨摩亚是南太平洋的心脏,是唯一位于赤道以南的美国领土。2020年美国
普查记录了49,710名居民,其中11,025人(4.1%)的人口年龄在50岁以上。目前,尚无已知的
记录了萨摩亚人中ADRD流行率的研究。我们的首要目标是建立
在我们先前工作的基础上,测试新的方法来提高ADRD的识字率和研究准备,改进检测
并建立在新生的研究基础设施上,以进行重要的表型和基因分型
美属萨摩亚ADRD的特征。我们的具体目标是:(1)测试ADRD知识、健康
识字,研究准备情况,并确定ADRD复原力和脆弱性因素,以及认知状态
在我们的概率样本中,使用文化适应工具对981名50岁以上的萨摩亚人进行了概率样本,(2)
使用NIA的统一数据集(UDSv3.0)在我们的概率样本中进行黄金标准评估
阿尔茨海默病研究中心计划以人群为基础确定MCI和ADRD的患病率
协调、数据共享和与其他组的比较,以及(3)交叉验证金标准痴呆症
遗传性(即载脂蛋白E)和血浆淀粉样蛋白-Tau-神经元损伤/神经变性(ATN)的评估
框架(例如,A40、A42、p-tau、nfl、GFAP),并与
为其他种族/民族群体提供的信息。
缺乏相关的临床和程序性知识阻碍了临床医生、科学家、
政策制定者,以及社区,以减少美属萨摩亚的ADRD差距。我们的短期目标是
确定ADRD在美国的流行情况,并研究导致ADRD的复原力和脆弱性因素
并与其他调查人员共享资源。我们的长期目标是促进未来的研究努力
增加准确和早期诊断,扩大获得护理的机会,并改善美属萨摩亚的健康结果。
