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. We compared age-adjusted death rates for AI/AN persons with those for Whites; Hispanics were excluded. RESULTS: From 2005 to 2009, the UI death rate for AI/AN people was 2.4 times higher than for Whites. Death rates for the 3 leading causes of UI death-motor vehicle traffic crashes, poisoning, and falls-were 1.4 to 3 times higher among AI/AN persons than among Whites. UI death rates were higher among AI/AN males than among females and highest among AI/AN persons in Alaska, the Northern Plains, and the Southwest. CONCLUSIONS: AI/AN persons had consistently higher UI death rates than did Whites. This disparity in overall rates coupled with recent increases in unintentional poisoning deaths requires that injury prevention be a major priority for improving health and preventing death among AI/AN populations.

Alcohol-attributable mortality among American Indians and Alaska Natives in the United States, 1999-2009.

OBJECTIVES: We describe the relative burden of alcohol-attributable death among American Indians/Alaska Natives (AI/ANs) in the United States. METHODS: National Death Index records were linked with Indian Health Service (IHS) registration records to identify AI/AN deaths misclassified as non-AI/AN. We calculated age-adjusted alcohol-attributable death rates from 1999 to 2009 for AI/AN and White persons by sex, age, geographic region, and leading causes; individuals of Hispanic origin were excluded. RESULTS: AI/AN persons had a substantially higher rate of alcohol-attributable death than Whites from 2005 to 2009 in IHS Contract Health Service Delivery Area counties (rate ratio = 3.3). The Northern Plains had the highest rate of AI/AN deaths (123.8/100,000), and the East had the lowest (48.9/100,000). For acute causes, the largest relative risks for AI/AN persons compared with Whites were for hypothermia (14.2) and alcohol poisoning (7.6). For chronic causes, the largest relative risks were for alcoholic psychosis (5.0) and alcoholic liver disease (4.9). CONCLUSIONS: Proven strategies that reduce alcohol consumption and make the environment safer for excessive drinkers should be further implemented in AI/AN communities.

Risk factors for 2009 pandemic influenza A (H1N1)-related hospitalization and death among racial/ethnic groups in New Mexico.

OBJECTIVES: We assessed risk factors for 2009 pandemic influenza A (H1N1)-related hospitalization, mechanical ventilation, and death among New Mexico residents. METHODS: We calculated population rate ratios using Poisson regression to analyze risk factors for H1N1-related hospitalization. We performed a cross-sectional analysis of hospitalizations during September 14, 2009 through January 13, 2010, using logistic regression to assess risk factors for mechanical ventilation and death among those hospitalized. RESULTS: During the study period, 926 laboratory-confirmed H1N1-related hospitalizations were identified. H1N1-related hospitalization was significantly higher among American Indians (risk ratio [RR] = 2.6; 95% confidence interval [CI] = 2.2, 3.2), Blacks (RR = 1.7; 95% CI = 1.2, 2.4), and Hispanics (RR = 1.8; 95% CI = 1.5, 2.0) than it was among non-Hispanic Whites, and also was higher among persons of younger age and lower household income. Mechanical ventilation was significantly associated with age 25 years and older, obesity, and lack of or delayed antiviral treatment. Death was significantly associated with male gender, cancer during the previous 12 months, and liver disorder. CONCLUSIONS: This analysis supports recent national efforts to include American Indian/Alaska Native race as a group at high risk for complications of influenza with respect to vaccination and antiviral treatment recommendations.
