Helicobacter pylori and stomach cancer among Native Americans in Northern Arizona

Stomach cancer is the third leading cause of cancer death globally. Rates for stomach cancer are 3-4 times higher among the Navajo Nation compared to the non-Hispanic white population in Arizona. Helicobacter pylori (H. pylori) plays a role in the healthy human gut, but it is also associated with multiple chronic diseases, including stomach cancer. A multi-year research program, conducted in partnership with Northern Arizona University through the Partnership for Native American Cancer Prevention, seeks to estimate the prevalence of H. pylori among Native Americans. The study in 2018 reported a 56.4% prevalence of H. pylori within participants from three Navajo chapters, with 72% of households having at least one infected person. This research program was expanded to continue the study through other regions of Navajo Nation. Together these studies will test hypotheses that the high H. pylori prevalence in Navajo communities correlates with environmental and behavioral factors as well as diagnostic delays and to determine the genotypes of H. pylori in Native Americans in Northern Arizona and antibiotic resistance to therapies.

An Asthma Collaboration to Reduce Childhood Asthma Disparities on the Navajo Nation

Asthma prevalence among Navajo children is 2 times that of the general population and is fueled by disparities including poverty, environmental pollutants, and minimally accessible healthcare. This project on the Navajo Nation will address these disparities using a community-based intervention targeting healthcare providers, schools, parents, children, and community members. This project was funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health.

K'é bee da' ahiiniita: Strength Through the Diné (Navajo) Clan System to Respond to the Gold King Mine Spill

There are estimates of over 500,000 abandoned mines in the US, many with the potential to impact health and economies of local communities. Developing a successful model of capacity building related to spill response has great potential to be valuable not only to the Diné but to communities vulnerable to environmental problems throughout the world. The K’é bee da’ahiiniita: Strength Through the Diné (Navajo) Clan System team focused on creating transformational change in the relationship of the Diné to the US government and other entities by building tribal capacity through training of Diné tribal college students, environmental interns, and community health representatives. Before this project, a study funded by the National Institute of Environmental Health Sciences was done to assess the short-term exposure and risk perceptions of the Gold King Mine spill. This project received funding support from the Agenese Nelms Haury Program in Environment and Social Justice in the form of a Challenge Grant.  Researchers for this project spanned multiple colleges and communities. A list of collaborators that are not currently part of the College of Public Health has been provided below.  Janene Yazzie, To’Bee Nihi Dziil, Mae-Gilene Begay, Navajo Community Health Representatives, Perry Charley, Diné College, Jani Ingram, Northern Arizona University, Manley Begay, Northern Arizona University, Rebecca Clausen, Fort Lewis College, Nicolette Teufel-Shone, Northern Arizona University

Cumulative Environmental Effects: Expanding Research with the Hopi Tribe

The overall goal of this project Cumulative Environmental Effects: Expanding Research with the Hopi Tribe is to use a community-based participatory research (CBPR) project is to collaborate with the Hopi Tribe investigating household exposures to inform policy decisions. Household exposures are major sources of environmental hazards encountered by many American Indian and Alaska Native (AI/AN) communities.  Household exposures include combustion by-products from heating and cooking, particulate from nearby mining and other land uses, and water and food contamination.  These exposures, and co-exposures such as unemployment and lower resilience, impact respiratory health and obesity among children and adults, and warrant evaluation of AI household exposures within a social ecological framework. The Hopi Tribe in Northern Arizona has identified several areas of concern, including the impact of burning coal and biomass in homes for heating and its potential impact on respiratory health. Other issues include concerns about arsenic and uranium species in drinking and surface water.  This application seeks to expand existing relationships to include Hopi officials in the Hopi Environmental Protection Office and university environmental scientists and health promotion experts. The project proposes to 1) Characterize magnitude of environmental exposures to particulate matter (PM), arsenic species, uranium and other contaminants from air, water, and food in selected households on Hopi tribal lands. 2) Evaluate how exposures are moderated by social determinants of health and social capital/community resilience, and 3) Expand Hopi capacity to address areas of environmental concern.  The effort will build additional capacity within the Hopi tribe to evaluate and mitigate propose mitigation for environmental hazards of concern to the tribe. The proposed joint project provides an opportunity to develop and strengthen a relationship built on trust between the Hopi tribe and university researchers and to increase the capacity of the Hopi Environmental Protection Office to monitor its air and water quality.  Anticipated results include modeling of cumulative exposures to arsenic and uranium species among Hopi residents and address environmental concerns of the tribe in terms of health inequities. The study will build Hopi capacity to conduct research of adverse exposures and develop informed tribal environmental and health policies for a sustainable future.

Building an Effective Tribal and Multijurisdictional Response Network to Improve Preparedness and Response

Problem Statement Effective public health preparedness and response (PHPR) requires a systems approach fully integrating all sector partners.  However, preparedness activities often take place in silos, resulting in ineffective multijurisdictional emergency responses.  Furthermore, although strengthening PHPR is a shared responsibility among federal, state, local, tribal, territorial, public and private organizations, integration of tribal public health partners is often lacking or far from ideal.  Tribal populations include individuals considered at-risk or vulnerable, including but not limited to persons with chronic diseases or disabilities, elderly community members, and residents of remote and isolated areas.  Supporting and sustaining an effective tribal and multijurisdictional response network will require determining which Preparedness and Emergency Response Research Center (PERRC) and Learning Center (PERLC) research, training, and technical assistance products can effectively be used, as well as how to adapt these products for effective tribal use.  Purpose This proposal will determine specific tribal and multijurisdictional PHPR needs, and adapt PERRC and PERLC products to meet these needs and support the transfer of PERRC and PERLC research outcomes and promising practices into the field.  These activities will provide validated models for improving health security nationally.  The proposed activities fall within Sub-project 3, as defined in the Centers for Disease Control and Prevention (CDC)/Association of Schools and Programs of Public Health (ASPPH) Request for Proposals (RFP).  The specific aims of our proposal are as follows: Aim 1a: Conduct a tribal needs assessment to validate existing knowledge, skills, and preparedness and response gaps. Aim 1b: Conduct a state and local needs assessment to validate existing collaboration gaps to bridge tribal partner intersections with state, local and territorial public health departments. Aim 2a: Provide targeted tribal evidence-based interventions using cultural frameworks for public health application to improve tribal readiness and capacity.  Aim 2b: Provide targeted state and local evidence-based interventions to improve the integration of tribal partners.  The needs assessments in Aims 1a and 1b will guide the selection of PERRC and PERLC products most appropriate to meet these needs.  These products will be adapted for tribal use in Aim 2a and Aim 2b for effectively integrating tribal populations into regional multijurisdictional response efforts.  The relation of the aims within a tribal and multijurisdictional response network is illustrated in Figure 1. The Mountain West Preparedness and Emergency Response Learning Center (MWPERLC) has extensive experience working collaboratively with tribal public health practitioners.  Given our proven ten year track record for successfully developing, initiating, implementing and evaluating innovative and sustainable tribal preparedness activities, we are well positioned to spearhead efforts for enhancing preparedness and the wellbeing of American Indian communities.

A Community Toolkit to Improve Asthma Care for Rural Children

More than four million people with asthma live outside of urban areas, and most are seen in primary care settings where their asthma is often inadequately managed, representing a significant gap in care. Rural health disparities for children with asthma include poverty, limited access to care, and environmental challenges including high levels of outdoor and indoor particulate exposure. The Asthma Toolkit program has translated evidence-based asthma care into both rural and urban primary care practices. Although this program has produced evidence of increased guidelines-concordant care, much room exists for improvement. We believe that by deploying Asthma Toolkit training in a larger program that includes community, school, and family engagement, quality of care and health outcomes can be improved for rural children with asthma. This project will bring together investigators from the University of Arizona and National Jewish Health to 1) engage three communities on the Navajo Nation to build a successful collaboration (U34); and 2) conduct a randomized pragmatic trial of a community rural pediatric asthma program (U01). During the initial empowerment phase, we will solidify relationships with community stakeholders including patients, parents, community leaders, hospital administrators, schools, and providers. A group of stakeholder advisors will be created to inform and guide the subsequent study.  In the second (U01) phase, we will employ a step wedge, randomized trial design to test the capacity of the Community Asthma Toolkit program to improve care and outcomes.  The provider component will include comprehensive training in evidence-based pediatric asthma care. The school component will work to improve capacity to identify pediatric asthma and facilitate communication between school, family, and provider. The hospital component will help provide structured communication between hospital clinicians and primary care providers to improve outpatient management and prevent unnecessary urgent care utilization. Finally, the air quality component will assess community and provider concerns about indoor and outdoor air quality and determine potential methods to measure and reduce environmental risks to children with asthma. The final trial will be modified in accord with stakeholder input during the engagement phase. We believe that the intervention could serve as a model for implementation of strategies to improve asthma care in rural children.
