项目摘要
PROJECT SUMMARY
As the US population ages, the number of people living with Alzheimer’s Disease and
related dementias (ADRD) is projected to triple by 2050. Although the life expectancy of
American Indian and Alaska Natives (AI/ANs) is much shorter than that of other US populations,
it has dramatically increased in the last few decades, with the expansion of the AI/AN elder
population expected to continue. Compared to most US populations, AI/ANs bear a
disproportionate burden of many established modifiable risk factors for dementia, such as
diabetes, obesity, and smoking. However, our knowledge about dementia in this population
remains to be severely limited. So far, only a handful of studies have examined dementia
among AI/ANs, with reliable data on the prevalence or incidence of dementia in this population
being nonexistent. Given so many gaps in our knowledge about dementia among AI/ANs, a
systematic investigation is urgently needed to identify how problematic dementia is in this
population and its impact on the Indian health system to enable more precise planning and
prioritization of resources needed to support relevant health care policy. Here, leveraging on 16
years of longitudinal data available in the Indian Health Service (IHS) Data Project, a synthesis
of existing IHS electronic health data for nearly 30% of the IHS service population (~ 640,000
AI/ANs), we propose to address 4 major knowledge gaps about dementia among AI/ANs as
guided by the following specific aims: (1) Estimate dementia prevalence, incidence, and
comorbidity rates among AI/AN elders by individual and community characteristics, such as
age, gender, location, and county level socioeconomic status; (2) Characterize the association
between dementia and potentially modifiable risk factors, such as diabetes, obesity, tobacco
use, binge drinking, traumatic brain injuries and depression; (3) Evaluate the influence of
dementia and comorbidity status on health service utilization patterns, including inpatient,
outpatient, and pharmacy services; and (4) Examine the costs of providing treatment among
AI/ANs with dementia, and factors that influence these costs such as comorbidity status. Our
proposed analyses will provide a relatively accurate and complete picture for the epidemiology
of diagnosed dementia among AI/ANs based on a large and geographically diverse sample, and
contribute to the understanding of dementia and associated health service utilization in an
extremely underserved population living in disadvantaged communities. Our findings promise to
lay groundwork for future studies on dementia to address both the needs of AI/ANs and those of
other similarly underserved populations.
项目概要
随着美国人口老龄化,患有阿尔茨海默氏病的人数和
预计到 2050 年,相关痴呆症 (ADRD) 将增加两倍。
美洲印第安人和阿拉斯加原住民 (AI/AN) 比美国其他人群的身高要短得多,
在过去的几十年里,随着 AI/AN 长老的扩展,它急剧增加
预计人口将继续增加。与大多数美国人相比,AI/AN 具有
许多已确定的可改变的痴呆风险因素造成了不成比例的负担,例如
糖尿病、肥胖和吸烟。然而,我们对这一人群痴呆症的了解
仍受到严格限制。到目前为止,只有少数研究检查了痴呆症
AI/AN 中,有关于该人群痴呆症患病率或发病率的可靠数据
不存在。鉴于我们对 AI/AN 痴呆症的了解存在很大差距,
迫切需要进行系统调查,以确定痴呆症在这方面的问题有多大
人口及其对印度卫生系统的影响,以实现更精确的规划和
支持相关医疗保健政策所需资源的优先顺序。在这里,利用 16
印度卫生服务 (IHS) 数据项目提供了多年的纵向数据,这是一个综合
近 30% 的 IHS 服务人群(约 640,000
AI/AN),我们建议解决 AI/AN 中关于痴呆症的 4 个主要知识差距:
遵循以下具体目标: (1) 估计痴呆症患病率、发病率和
按个人和社区特征划分的 AI/AN 老年人的合并症率,例如
年龄、性别、地点和县级社会经济地位; (2) 关联的特征
痴呆症与潜在可改变的危险因素(如糖尿病、肥胖、烟草)之间的关系
使用、酗酒、脑外伤和抑郁症; (3) 评估影响
痴呆症和合并症状况对卫生服务利用模式的影响,包括住院患者、
门诊和药房服务; (4) 审查提供治疗的费用
患有痴呆症的 AI/AN 以及影响这些费用的因素,例如合并症状况。我们的
拟议的分析将为流行病学提供相对准确和完整的情况
基于大量且地域多样的样本,诊断出 AI/AN 中的痴呆症,以及
有助于了解痴呆症和相关医疗服务的利用
生活在贫困社区的服务极度匮乏的人群。我们的研究结果有望
为未来的痴呆症研究奠定基础,以满足 AI/AN 和人类的需求
其他类似的服务不足的人群。
