Reports & Articles

The Alaska Native Epidemiology Center (EpiCenter) produces health reports that provide statewide and regional level data to tribal health organizations and other entities working to improve the health of Alaska Native people.

Additionally, EpiCenter staff author manuscripts on public health topics which are published in peer-reviewed journals to inform others interested in improving Alaska Native health.

Highlights

Alaska Native Injury Atlas, 4th Edition

Part 1: Injury Deaths

Unlike prior editions of the Atlas, the fourth edition comprises three independent parts: deaths, hospitalizations, and a poisoning and suicide attempt supplement using hospital discharge data.

Part 1 of this report provides an update of injury deaths among Alaska Native and American Indian people reported in the State of Alaska. It describes the leading causes of injury related death statewide and within each region. Monitoring injury deaths over time can help identify which injury prevention efforts have been effective and which may need to be increased or modified. In addition, this surveillance can identify disparities and trends to help prioritize the most vulnerable populations with injury prevention efforts. 66 pages.
