The burden of Alzheimer's disease and related dementias (ADRD) has increased substantially in the United States, particularly in health disparity populations. Little is known about the epidemiology of ADRD in American Indian (AI) adults, although they have a high prevalence of ADRD risk factors including hypertension, diabetes, obesity, and smoking. Using electronic health records from a large health care organization during 2016-18, we describe characteristics of AI patients aged ≥55 years with and without an ADRD diagnosis, assess ADRD risk factors and contrast findings with results from age- and sex-matched non- Hispanic White (NHW) patients. To identify factors associated with ADRD diagnoses, we estimated population-averaged prevalence rate ratios to approximate relative risk (RR) using generalized estimating equations models adjusted for age, sex, and marital and rural residency status. The age-adjusted prevalence of ADRD diagnosis was 6.6% of AI patients, compared with 4.4% in NHW patients. Patient age and diagnosis of hypertension, depression, hyperlipidemia, or diabetes were significantly associated with higher risk of ADRD diagnosis in AIs (RR range: 1.1-2.8) whereas female sex or being married/having a partner were associated with lower risk of ADRD diagnosis (each RR=.7). ADRD risk factors were generally similar between AI and NHW patients, except for sex and marital status. However, the adjusted risk of ADRD was approximately 49% higher in AI patients. To our knowledge, our study is the first to examine ADRD diagnoses and comorbidities in AIs across a large geographical region in southwest United States. Future efforts to confirm our findings in diverse AI communities are warranted. Ethn Dis. 2020;30(4):671-680; doi:10.18865/ed.30.4.671

The University of Washington Twin Registry is a unique community-based registry of twin pairs who join specifically to participate in scientific research. It was founded in 2002 to serve as a resource for investigators throughout the scientific community. Current enrollment exceeds 7,200 pairs, and plans are in place to increase enrollment to 10,000 pairs by 2015. In addition to serving as a recruitment base for new research studies, the registry maintains extensive and continually expanding survey data on physical and mental health, as well as a biorepository that includes DNA from more than 8,800 individual twins. The registry is engaged in linking member data to birth records and to diagnostic and procedure variables for hospital-based care provided to members in Washington State. It also incorporates several innovative variables relevant to the built and social environments, which were created by geocoding twin addresses and linking the resulting coordinates to geospatial information systems databases. This combination of existing data and biospecimens, characterizing a group of twins who are willing to participate in research, is a valuable resource for the new wave of twin studies. These include 'omics', epigenetics, gene-by-environment interactions, and other novel methods to understand human health.

In rural Native American communities, access to healthy foods is limited and diet-related disparities are significant. Tribally owned and operated convenience stores, small food stores that sell ready-to-eat foods and snacks primarily high in fat and sugar, serve as the primary and, in some areas, the only food stores. The Tribal Health and Resilience in Vulnerable Environments or "THRIVE" study, implemented between 2013 and 2018, is the first healthy retail intervention study implemented in tribally owned and operated convenience stores. THRIVE aims to increase vegetable and fruit intake among Native Americans living within the Chickasaw and Choctaw Nation of Oklahoma. The study comprises three phases: 1) formative research assessing tribal community food environments and associated health outcomes; 2) intervention development to assess convenience stores and tailor healthy retail product, pricing, promotion, and placement strategies; and 3) intervention implementation and evaluation. In this paper we share the participatory research process employed by our tribal-university partnership to develop this healthy retail intervention within the unique contexts of tribal convenience stores. We summarize our methods to engage tribal leaders across diverse health, government, and commerce sectors and adapt and localize intervention strategies that test the ability of tribal nations to increase fruit and vegetable purchasing and consumption among tribal members. Study processes will assist in developing a literature base for policy and environmental strategies that intervene broadly to improve Native community food environments and eliminate diet-related disparities among Native Americans.
