Unintentional injury mortality among American Indians and Alaska Natives in the United States, 1990-2009.

Objectives: We describe the burden of unintentional injury (UI) deaths among American Indian and Alaska Native (AI/AN) populations in the United States.

Methods: National Death Index records for 1990 to 2009 were linked with Indian Health Service registration records to identify AI/AN deaths misclassified as non-AI/AN deaths. Most analyses were restricted to Contract Health Service Delivery Area counties in 6 geographic regions of the United States.

The decrease in the unintentional injury mortality disparity between American Indians/Alaska Natives and non-American Indians/Alaska Natives in New Mexico, 1980 to 2009.

Objectives: We tracked the unintentional injury death disparity between American Indians/Alaska Natives and non-American Indians/Alaska Natives in New Mexico, 1980 to 2009.

Methods: We calculated age-adjusted rates and rate ratios for unintentional injury deaths and their external causes among American Indians/Alaska Natives and non-American Indians/Alaska Natives. We tested trend significance with the Mann-Kendall test.
