The Role of Community Engagement in Successful Recruitment of Research Participants During the Covid-19 Pandemic
Background: Our research team was in the process of recruiting American Indian and Alaska Native (AIAN) women for a community-based intervention to prevent alcohol-exposed pregnancy when the COVID-19 pandemic began. Safety measures adopted at the tribal, state, and national level required us to rethink and revise study protocols. We followed the principles of community-based participatory research, especially community engagement. The goal of thi…
Reach, Acceptability, and Sustainability of the Native Changing High-Risk Alcohol Use and Increasing Contraception Effectiveness Study (CHOICES) Intervention
American Indian (AI) women are at risk of alcohol-exposed pregnancy (AEP) due to the higher prevalence of alcohol use disorders (AUDs) and risky drinking. The Native Changing High-Risk Alcohol Use and Increasing Contraception Effectiveness Study (Native CHOICES) was implemented in partnership with a Northern Plains Tribal community to address the effectiveness of a brief, motivational interviewing-based intervention to reduce AEP risk among adult…
Assessing the validity of the American Indian Enculturation Scale in Alaska Native adults interested in reducing alcohol use
The American Indian Enculturation Scale (AIES) was developed for American Indian populations to measure connection to traditional culture, but it has not been evaluated in Alaska Native people. While American Indian and Alaska Native individuals are grouped together, significant differences exist between groups. As a part of a randomized controlled trial for contingency management to reduce alcohol use, 160 Alaska Native adults completed the AIES…
Food insecurity in urban American Indian and Alaska Native populations during the Covid-19 pandemic
High rates of food insecurity among American Indian and Alaska Native communities likely increased during the COVID-19 pandemic. However, despite the high prevalence of food insecurity, community-led efforts to reduce COVID-19 infection and increase vaccination uptake across Indian Health Service and Tribal healthcare facilities may have mitigated the negative impacts of the pandemic for families experiencing food insecurity. These successful app…
Epidemiology of Head Injury and Associations with Clinical and Neuropsychological Test Scores in Older American Indians
Native opportunities to stop hypertension
Introduction: American Indian and Alaska Native (AI/AN) adults experience disproportionate cardiovascular disease (CVD) morbidity and mortality compared to other races, which may be partly attributable to higher burden of hypertension (HTN). Dietary Approaches to Stop Hypertension (DASH) is a high-impact therapeutic dietary intervention for primary and secondary prevention of CVD that can contribute to significant decreases in systolic blood pres…

Factors That Influence Risk Perceptions and Successful Covid-19 Vaccination Communication Campaigns With American Indians
COVID-19 vaccinations are the primary tool to end the pandemic. However, vaccine hesitancy continues to be a barrier to herd-immunity in the United States. American Indians (AI) often have higher levels of distrust in western medicine and lower levels of satisfaction with health care when compared to non-Hispanic Whites. Yet AIs have high COVID-19 vaccination rates. We discuss factors that influence AI risk perceptions of COVID-19 vaccinations in…
Cardiovascular Disease Risk Factors and Health Outcomes Among American Indians in Oklahoma
CVD risk factors and health outcomes persist among American Indians even as some risks (e.g., smoking) appear to be stabilizing or even declining in the general US population. Efforts to include American Indians in national health surveys, implement broad reaching environmental and policy interventions, and address the social determinants of health are critical to the elimination of these disparities
Addressing the Challenges of Research With Small Populations
Public health policy relies on accurate data, which are often unavailable for small populations, especially indigenous groups. Yet these groups have some of the worst health disparities in the United States, making it an ethical imperative to explore creative solutions to the problem of insufficient data. We discuss the limits of widely applied methods of data aggregation and propose a mixed-methods approach to data borrowing as a way to augment …
