Spatial Epidemiology of Alcohol- and Drug-Related Health Problems Among Northern Plains American Indians: Nebraska and South Dakota, 2007 to 2012.

BACKGROUND: Despite high abstinence rates, American Indians experience elevated rates of many alcohol and other drug problems. American Indians also predominantly reside in poor and rural areas, which may explain some observed health disparities. We investigated whether geographic areas including reservations or large American Indian populations exhibited greater incidence of alcohol- and drug-related hospitalizations. METHODS: We obtained inpatient hospitalization records for 2 Northern Plain states (Nebraska and South Dakota) for the years 2007 to 2012. We constructed zip code counts for 10 categories of hospitalization with diagnoses or injury causation commonly associated with alcohol or drug use. We related these to community sociodemographic characteristics using Bayesian Poisson space-time regression models and examined associations with and without controls for whether each zip code was located within an American Indian reservation. RESULTS: Controlling for other demographic and economic characteristics, zip codes with greater percentage of American Indians exhibited greater incidence for all 10 substance abuse-related health outcomes (9 of 10 well supported); zip code areas within American Indian reservations had greater incidence of self-inflicted injury and drug dependence and abuse, and reduced incidence of alcohol cirrhosis and prescription opioid poisoning. However, the analyses generally demonstrated no well-supported differences in incidence associated with local residence percentages of American Indian versus African American. CONCLUSIONS: In our analyses, ethnicity or heredity alone did not account for alcohol- and drug-related hospitalizations among Native populations. Aspects of social, economic, and political dimensions of Native lives must be considered in the etiology of alcohol- and drug-related problems for rural-dwelling indigenous peoples.

Impacts of alcohol availability on Tribal lands where alcohol is prohibited: A community-partnered qualitative investigation.

On a Northern Plains reservation where alcohol was prohibited, we investigated community members' views on the impacts of alcohol availability. Our methods combined elements of Tribal community participatory research with qualitative inquiry to elicit these perspectives. We used rapid appraisal techniques to conduct confidential interviews with 31 key leaders representing 7 relevant major community systems, and representing a variety of perspectives. Topics included respondents' understandings of the current systems of alcohol availability and use on the reservation, the impacts of these systems on reservation residents, and possible ways to measure these impacts. Respondents reported impacts on individuals, families, and the tribe overall. Alcohol-related problems shaped and were shaped by a constellation of social-ecological conditions: kinship, housing, employment, public/social service capacity, and the supply of alcohol in nearby off-reservation areas, as well as inter-governmental relationships and the spiritual life of reservation residents. A variety of social-structural determinants magnified alcohol impacts, so that the problem drinking of a small number of individuals could have broad effects on their families and the entire community. Our participatory qualitative methods enabled us to directly include the voices as well as the personal experiences and expertise of community members in this presentation. These methods may be broadly applied within policy analysis to identify ways to reduce harms related to alcohol and other drugs for Indigenous communities.
