ABSTRACT Cardiovascular disease (CVD) is the leading cause of death among American Indians. The objective of this study was to assess trends in CVD and CVD risk factors among American Indians in Montana.
In 1999 and 2003, 1000 American Indian adults aged > or =18 years living on or near the seven reservations in Montana were interviewed each year using an adapted Behavior Risk Factor Surveillance System survey.
During the 5-year period from 1999 to 2003, the prevalence of CVD risk factors increased significantly: diabetes (12% to 16%), high blood pressure (26% to 34%), high cholesterol (23% to 30%), and obesity (34% to 39%). The percentage reporting current smoking was stable and remained high (38% to 36%). After adjusting for age and gender, the increases in high blood pressure, high cholesterol, and obesity remained significant. The percentage reporting two or more CVD risk factors increased significantly overall, among men and women, and among older and younger respondents during the 5-year time period.
The prevalence of CVD risk factors among American Indian adults in Montana is high, and for many of the risk factors, has increased significantly over a 5-year period.

    ABSTRACT: The 2004 Behavioral Risk Factor Surveillance System (BRFSS) survey was administered to American Indian/Alaska Native (AI/AN) adults in Nevada to determine whether health disparities exist between AI/ANs and the state's general population. Results showed AI/ANs were 1.5 times more likely to smoke cigarettes, 3.5 times more likely to be exposed to secondhand smoke, 3.2 times more likely to lack leisure-time physical activity, 9.7 times more likely to report fair/poor health status, and 7.7 times more likely to have a dis- ability. In addition, AI/ANs were more likely to have current asthma (OR=5.0) and diabetes (OR=1.8). AI/AN women were 4.8 times as likely to report no Pap test in the past 3 years. Our findings suggest that Nevada's AI/AN population face many health disparities related to risk behaviors, poor health status and health conditions, and healthcare access. Partnerships among tribal, state and federal public health systems are needed to address these disparities.

    ABSTRACT: With low rates of the risk factors for cardiovascular disease as recently as 40 years ago, the rates of cardiovascular disease (CVD) in American Indians and Alaska Natives were exceedingly low. Despite recent large-scale efforts to eliminate health disparities in ethnic and minority populations, the impact among American Indian and Alaska Natives to date has been relatively limited. Indeed, over the past several decades the incidence and prevalence of cardiovascular risk factors has risen significantly, including the development of an epidemic of diabetes. Evidence suggests that these higher rates of cardiovascular risk factors, including tobacco abuse, diabetes, high blood pressure, and elevated cholesterol levels, may be placing an inordinate burden of cardiovascular disease on the American Indian and Alaska Native population. The rates of heart disease and stroke among American Indians and Alaska Natives are now higher than in the general U.S. population as well as in U.S. whites. Recent evaluations suggest that these rates are also higher than among other ethnic or racial populations in the United States. Additionally, American Indians and Alaska Natives have been found to have a substantially higher proportion of premature death from heart disease when compared with other ethnic and racial populations. A number of recent prevention initiatives and focused clinical efforts are making promising strides toward reduced disparities in cardiovascular health with primordial, primary, and secondary cardiovascular prevention efforts along with enhanced early identification and therapeutic intervention for more favorable cardiovascular outcomes in the future. In order to reach our goals of heart-healthy and stroke-free American Indians and Alaska Natives, implementation of an aggressive, reasonably resourced, systemic plan of coordinated health promotion, risk reduction, and disease control efforts are necessary, with appropriate policy and legislative support.

    ABSTRACT: Previous studies suggested that the cancer incidence rates in American Indians and Alaska Natives were lower than in other groups. The objective of this study was to compare the cancer incidence rates in American Indians and whites in Montana. Age-adjusted 6-year cancer incidence rates were calculated for American-Indian and white men and women in Montana to allow comparison of rates in 1991-1996 to those in 1997-2002. The age-adjusted rates for American-Indian men were significantly higher than those for white men for all cancer sites (755+/-74 [95% confidence interval] per 100,000 vs 544+/-9 per 100,000), lung cancer (167+/-35 per 100,000 vs 83+/-4 per 100,000), and colorectal cancer (115+/-29 per 100,000 vs 61+/-4 per 100,000) from 1997 to 2002. The adjusted rates for American-Indian women were significantly higher than those for white women for all cancer sites (526+/-47 per 100,000 vs 412+/-8 per 100,000) and lung cancer (120+/-24 per 100,000 vs 56+/-3 per 100,000) during this same time period. There was a significant increase in the age-adjusted rates for all cancer sites among white men and women but not for American-Indian men or women between 1991-1996 and 1997-2002. There is a significant disparity in the cancer incidence rates between American Indians and whites in Montana. Regional or state-level surveillance data will be needed to describe the changing patterns of cancer incidence in many native communities in the United States.
