Comparison of circulating and excreted metals and of autoimmunity between two Great Plains Tribal communities.

Metals contaminants of the environment from mine waste have been implicated as contributing agents in autoimmune disease. The current study compares metals and autoimmunity in two Tribal communities residing in the Black Hills and the Bighorn Mountains geographical regions that are scattered with extant hard rock mines. With documented drinking water contamination in both communities, in vivo levels of more than half of the measured serum and urine metals differed between the two communities and were substantially different from their national median values.

Community based participatory research approaches to combat oral health inequities among American Indian and Alaska Native populations.

American Indian and Alaska Native (AI/AN) communities have experienced a history of systemic racism and still face significant oral health disparities. These disparities extend to the youngest community members in the form of early childhood caries (ECC). Although behavior and biology contribute to ECC, the conditions where people live, grow, and work, and the systems and political and economic forces that shape individual health outcomes, are thought to greatly impact ECC among AI/AN populations.

A Formative Assessment of Social Determinants of Health Related to Early Childhood Caries in Two American Indian Communities.

In the United States, children from diverse ethnic groups and those with low socioeconomic status are at a significantly increased risk for early childhood caries. Despite the efforts focused on decreasing early childhood caries in American Indian (AI) populations, these children have the highest incidence of dental caries of any ethnic group, with four times the cases of untreated dental caries compared to white children. This qualitative formative assessment was conducted in two AI communities.

Our Relationship to Water and Experience of Water Insecurity among Apsáalooke (Crow Indian) People, Montana.

Affordable access to safe drinking water is essential to community health, yet there is limited understanding of water insecurity among Native Americans. Therefore, the focus of this paper is to describe Apsáalooke (Crow Indian) tribal members' experiences with water insecurity. For Apsáalooke people, local rivers and springs are still vitally important for traditional cultural activities.

Metagenomic Profiling of Microbial Pathogens in the Little Bighorn River, Montana.

The Little Bighorn River is the primary source of water for water treatment plants serving the local Crow Agency population, and has special significance in the spiritual and ceremonial life of the Crow tribe. Unfortunately, the watershed suffers from impaired water quality, with high counts of fecal coliform bacteria routinely measured during run-off events. A metagenomic analysis was carried out to identify potential pathogens in the river water.

Guardians of the Living Water: Using a Health Literacy Framework to Evaluate a Child as Change Agent Intervention.

Background: American Indian communities in the United States experience considerable health inequities, including increased exposure to environmental contaminants. Consequently, community members of the Apsáalooke (Crow) Nation identified the lack of water-related environmental knowledge among children as an area of concern.

Aim: The purpose of this study was to provide a feasibility evaluation of an increasingly sophisticated environmental health literacy program for children.

Challenges and Opportunities for Tribal Waters: Addressing Disparities in Safe Public Drinking Water on the Crow Reservation in Montana, USA.

Disparities in access to safe public drinking water are increasingly being recognized as contributing to health disparities and environmental injustice for vulnerable communities in the United States. As the Co-Directors of the Apsaálooke Water and Wastewater Authority (AWWWA) for the Crow Tribe, with our academic partners, we present here the multiple and complex challenges we have addressed in improving and maintaining tribal water and wastewater infrastructure, including the identification of diverse funding sources for infrastructure construction, the need for many kinds of specialized expertise and long-term stability of project personnel, ratepayer difficulty in paying for services, an ongoing legacy of inadequate infrastructure planning, and lack of water quality research capacity. As a tribal entity, the AWWWA faces additional challenges, including the complex jurisdictional issues affecting all phases of our work, lack of authority to create water districts, and additional legal and regulatory gaps-especially with regards to environmental protection.

Community Engaged Cumulative Risk Assessment of Exposure to Inorganic Well Water Contaminants, Crow Reservation, Montana.

An estimated 11 million people in the US have home wells with unsafe levels of hazardous metals and nitrate. The national scope of the health risk from consuming this water has not been assessed as home wells are largely unregulated and data on well water treatment and consumption are lacking. Here, we assessed health risks from consumption of contaminated well water on the Crow Reservation by conducting a community-engaged, cumulative risk assessment.

Community-based research as a mechanism to reduce environmental health disparities in american Indian and alaska native communities.

Racial and ethnic minority communities, including American Indian and Alaska Natives, have been disproportionately impacted by environmental pollution and contamination. This includes siting and location of point sources of pollution, legacies of contamination of drinking and recreational water, and mining, military and agricultural impacts. As a result, both quantity and quality of culturally important subsistence resources are diminished, contributing to poor nutrition and obesity, and overall reductions in quality of life and life expectancy.

"Exploring Effects of Climate Change on Northern Plains American Indian Health".

American Indians have unique vulnerabilities to the impacts of climate change because of the links among ecosystems, cultural practices, and public health, but also as a result of limited resources available to address infrastructure needs. On the Crow Reservation in south-central Montana, a Northern Plains American Indian Reservation, there are community concerns about the consequences of climate change impacts for community health and local ecosystems. Observations made by Tribal Elders about decreasing annual snowfall and milder winter temperatures over the 20 century initiated an investigation of local climate and hydrologic data by the Tribal College.

Community-based participatory research in Indian country: improving health through water quality research and awareness.

Water has always been held in high respect by the Apsaálooke (Crow) people of Montana. Tribal members questioned the health of the rivers and well water because of visible water quality deterioration and potential connections to illnesses in the community. Community members initiated collaboration among local organizations, the tribe, and academic partners, resulting in genuine community-based participatory research.
