Food insecurity in urban American Indian and Alaska Native populations during the COVID-19 pandemic.

Background: Food insecurity is an important social determinant of health that was exacerbated by the COVID-19 pandemic. Both food insecurity and COVID-19 infection disproportionately affect racial and ethnic minority groups, particularly American Indian and Alaska Native communities; however, there is little evidence as to whether food insecurity is associated with COVID-19 infection or COVID-19 preventive behaviors such as vaccination uptake. The purpose of this study was to evaluate associations between food insecurity, COVID-19 infection, and vaccination status among urban American Indian and Alaska Native adults seen at 5 clinics serving urban Native people.

The PhenX Toolkit: Recommended Measurement Protocols for Social Determinants of Health Research.

Health disparities are driven by unequal conditions in the environments in which people are born, live, learn, work, play, worship, and age, commonly termed the Social Determinants of Health (SDoH). The availability of recommended measurement protocols for SDoH will enable investigators to consistently collect data for SDoH constructs. The PhenX (consensus measures for Phenotypes and eXposures) Toolkit is a web-based catalog of recommended measurement protocols for use in research studies with human participants.

Purpose: Our goal was to describe urban AI/AN parental attributes associated with COVID-19 vaccination of their children.

The CPT1A Arctic variant: perspectives of community members and providers in two Alaska tribal health settings.

Newborn screening in Alaska includes screening for carnitine palmitoyltransferase 1A (CPT1A) deficiency. The CPT1A Arctic variant is a variant highly prevalent among Indigenous peoples in the Arctic. In this study, we sought to elicit Alaska Native (AN) community member and AN-serving healthcare providers' knowledge and perspectives on the CPT1A Arctic variant.

Evaluating COVID-19 Response Within a Tribal Health Care Organization.

Introduction: Health care organizations of all types have adapted in response to COVID-19. Responding to the pandemic has varied across organizations and there are few standardized frameworks from which to evaluate an organizational response. This article reports COVID-19 responses by a tribal health care organization using a synthesized evaluation framework that integrated the organizational values and allowed for timely implementation of responses during this COVID-19 public health emergency.

Identification of Sociodemographic, Clinical, and Genetic Factors to Aid Alaska Native and American Indian People to Successfully Quit Smoking.

Introduction: Alaska Native and American Indian (ANAI) people have a smoking prevalence of 23%. Nicotine metabolite ratio (NMR) and genetic testing may enable tailored selection of tobacco cessation medication.

Aims And Methods: The purpose of this study was to evaluate the relative contributions of NMR, cessation medication, demographics, and tobacco use history to cessation.

Retention in a 6-Month Smoking Cessation Study Among Alaska Native and American Indian People.

Participant retention in longitudinal health research is necessary for generalizable results. Understanding factors that correlate with increased retention could improve retention in future studies. Here, we describe how participant and study process measures are associated with retention in a longitudinal tobacco cessation research study performed in Anchorage, Alaska.

Measuring Attitudes About Alcohol Misuse and Dependence Among Alaska Native People Within a Tribal Health Care System.

Objectives: Attitudes about alcohol misuse and dependence influence alcohol use and help-seeking behavior. Alaska Native and American Indian (AN/AI) people have higher rates of alcohol-related morbidity and mortality but engage in treatment at lower rates than the general population. No validated instruments exist to assess attitudes of AN/AI people about alcohol misuse and dependence to inform treatment and prevention efforts.

Patient and primary care perspectives on hypertension management: short report of a qualitative study in a tribal health system.

The prevalence of self-reported hypertension is higher among Alaska Native and American Indian (ANAI) individuals than in the majority USA population. Although hypertension is the primary modifiable risk factor for cardiovascular disease and stroke, it can be difficult to manage successfully. The objective of this study was to explore patients' and providers' perspectives about hypertension, hypertension management strategies, and patient-provider communication strategies within a tribally-owned and operated health system in Alaska.

Choice of home blood pressure monitoring device: the role of device characteristics among Alaska Native and American Indian peoples.

Background: Home blood pressure monitoring (HBPM) is an effective tool in treatment and long-term management of hypertension. HBPM incorporates more data points to help patients and providers with diagnosis and management. The characteristics of HBPM devices matter to patients, but the relative importance of the characteristics in choosing a device remains unclear.

Nicotine metabolism and its association with CYP2A6 genotype among Indigenous people in Alaska who smoke.

Prevalence of smoking is higher in Alaska Native and American Indian (ANAI) populations living in Alaska than the general US population. Genetic factors contribute to smoking and cessation rates. The objective of this study was to compare CYP2A6 genetic variation and CYP2A6 enzyme activity toward nicotine in an ANAI population.

Best Practices for Conducting Clinical Trials With Indigenous Children in the United States.

We provide guidance for conducting clinical trials with Indigenous children in the United States. We drew on extant literature and our experience to describe 3 best practices for the ethical and effective conduct of clinical trials with Indigenous children. Case examples of pediatric research conducted with American Indian, Alaska Native, and Native Hawaiian communities are provided to illustrate these practices.

Home Blood Pressure Monitoring Devices: Device Performance in an Alaska Native and American Indian Population.

Home blood pressure monitoring (HBPM) is an important component of blood pressure (BP) management. We assessed performance of two HBPM devices among Alaska Native and American Indian people (ANAIs). We measured BP using Omron BP786 arm cuff, Omron BP654 wrist cuff, and Baum aneroid sphygmomanometer in 100 ANAIs.

Effect of Incentives for Alcohol Abstinence in Partnership With 3 American Indian and Alaska Native Communities: A Randomized Clinical Trial.

Importance: Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders.

Objective: To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition.

Characterization of CYP3A pharmacogenetic variation in American Indian and Alaska Native communities, targeting CYP3A4*1G allele function.

The frequencies of genetic variants in the CYP3A4 and CYP3A5 genes differ greatly across global populations, leading to profound differences in the metabolic activity of these enzymes and resulting drug metabolism rates, with important consequences for therapeutic safety and efficacy. Yet, the impact of genetic variants on enzyme activity are incompletely described, particularly in American Indian and Alaska Native (AIAN) populations. To characterize genetic variation in CYP3A4 and CYP3A5 and its effect on enzyme activity, we partnered with AIAN people living in two regions of Alaska: Yup'ik Alaska Native people living in the Yukon-Kuskokwim Delta region of rural southwest Alaska and AIAN people receiving care at the Southcentral Foundation in Anchorage, Alaska.

Alaska Native genomic research: perspectives from Alaska Native leaders, federal staff, and biomedical researchers.

Meaningful engagement of Alaska Native (AN) tribes and tribal health organizations is essential in the conduct of socially responsible and ethical research. As genomics becomes increasingly important to advancements in medicine, there is a risk that populations not meaningfully included in genomic research will not benefit from the outcomes of that research. AN people have historically been underrepresented in biomedical research; AN underrepresentation in genomics research is compounded by mistrust based on past abuses, concerns about privacy and data ownership, and cultural considerations specific to this type of research.

Pilot of a screening, brief intervention and referral to treatment process for symptoms of trauma among primary care patients.

Background: For populations with high rates of trauma exposure yet low behavioural health service use, identifying and addressing trauma in the primary care setting could improve health outcomes, reduce disability and increase the efficiency of health system resources.

Objective: To assess the acceptability and feasibility of a screening, brief intervention and referral to treatment (SBIRT) process for trauma and symptoms of posttraumatic stress disorder (PTSD) among American Indian and Alaska Native people. We also examine the short-term effects on service utilization and the screening accuracy of the Primary Care Posttraumatic Stress Disorder Screen.

An Internet-Based Therapeutic Tool for American Indian/Alaska Native Adults With Posttraumatic Stress Disorder: User Testing and Developmental Feasibility Study.

Background: Posttraumatic stress disorder (PTSD) is a major public health concern among American Indian and Alaska Native populations. Primary care clinics are often the first point of contact for American Indian and Alaska Natives seeking health care and are feasible locations for trauma-focused interventions.

Objective: Web-based therapeutic interventions have the potential to reduce PTSD symptoms by offering psychoeducation and symptom self-management tools.

Pharmacogenomics of Nicotine Metabolism: Novel CYP2A6 and CYP2B6 Genetic Variation Patterns in Alaska Native and American Indian Populations.

Introduction: Alaska Native and American Indian (AN/AI) populations have higher tobacco use prevalence than other ethnic/racial groups. Pharmacogenetic testing to tailor tobacco cessation treatment may improve cessation rates. This study characterized polymorphic variations among AN/AI people in genes associated with metabolism of nicotine and drugs used for tobacco cessation.

VKORC1 and Novel CYP2C9 Variation Predict Warfarin Response in Alaska Native and American Indian People.

Alaska Native and American Indian (AN/AI) people have unique pharmacogene variation that may affect warfarin disposition and therapeutic response. We performed targeted genotyping for cytochrome P450 (CYP)2C9, vitamin K epoxide oxidase reductase complex subunit 1 (VKORC1), CYP4F2, CYP4F11, and gamma-glutamyl carboxylase (GGCX) variants in AN/AI people receiving warfarin. The primary outcome was stable warfarin dose, defined as one dose, and associated international normalized ratio within the target range, at least 6 months after starting therapy, with two matching doses at least 2 weeks apart.
