Among American Indian/Alaska Native Research Articles

Occurrence of Endocrine and Thyroid Cancers Among Alaska Native People, 1969-2013.

Nationwide, the incidence of thyroid cancer is lower among American Indian/Alaska Native (AI/AN) people than among U.S. whites (USW). However, little is known about the incidence of thyroid or other endocrine cancers specifically among Alaska Native (AN) people. Data were examined from the National Cancer Institute's Surveillance, Epidemiology, and End Results Alaska Native Tumor Registry on endocrine cancers diagnosed among AN people from 1969-2013, with a specific focus on thyroid cancers. Frequencies of endocrine cancers by site and also of thyroid cancers by histology, size, and stage at diagnosis were evaluated. Distributions were compared to USW (Surveillance, Epidemiology, and End Results 9 Registries) using the chi-square test. Five-year average annual age-adjusted incidence rates of thyroid cancers were calculated, stratified by histology, age, and five-year period of diagnosis, and compared to those observed among USW. Five-year cause-specific survival was evaluated using cause of death data from the National Death Index Plus from the National Center for Health Statistics. During the 45-year period (1969-2013), 224 endocrine cancers were diagnosed among AN people, of which 210 (94%) were thyroid cancers. Compared to USW, AN people were diagnosed at a slightly younger age, had a higher proportion of thyroid cancers diagnosed with a size of 20-40 mm, and a larger proportion of patients with regional metastases. More than 85% of AN thyroid cancers were of papillary histology. The incidence of thyroid cancers was similar between AN people and USW, and appeared to increase among AN people over the period of surveillance. Finally, five-year cause-specific survival rate was 100% for papillary carcinoma patients and 86.3% [confidence interval 54.7-96.5] for follicular thyroid cancer patients. This study is the first report of endocrine cancers and the first detailed examination of thyroid cancer among AN people. The incidence of thyroid cancer was similar among AN people and USW. However, compared to USW, AN people appear to be at risk for diagnosis at a younger age, larger size, and higher stage. Further research is needed to explore the causes of these differences.

Tailoring an Alcohol Intervention for American Indian Alaska Native Women of Childbearing Age: Listening to the Community.

Reduction of risky drinking in women of childbearing age is 1 strategy that may be employed to prevent fetal alcohol spectrum disorder, a sequela of prenatal alcohol exposure. Communities differ in risk and protective factors, necessitating culturally informed interventions for maximal efficacy. This article describes the modification of an existing web-based screening, brief intervention, and referral to treatment intervention to reduce risky drinking among American Indian Alaska Native (AIAN) women of childbearing age in Southern California into a peer-to-peer-based intervention using motivational interviewing (MI). The modification process was iterative and included various community focus groups, interviews, and a final review. Intervention modification was required for cultural congruence. Components of the peer-to-peer intervention designed by this project included a flip chart used to guide the motivational interviewing, charts of the financial and physical costs of alcohol consumption, revised baseline and follow-up questionnaires, and guidance regarding the application of MI techniques. This study may inform the modification of future interventions among AIAN communities.

Sleep Quality in an Adult American Indian Community Sample.

Epidemiological studies have found that insufficient sleep (< 7 h/night) is more common among American Indians/Alaska Natives (AI/AN). In this study we sought to identify specific demographic, clinical, and cultural factors that may be associated with reduced sleep quality in an American Indian community sample. Information on demography along with personal medical, psychiatric, and drinking history was obtained using the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA). Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). The adult participants (n = 386, 54% women) had a mean ± standard deviation age of 31.35 ± 14.4 y. Higher degrees of AI ancestry, but not cultural identification, being older than 30 y, and having a high school diploma all were factors predictive of having a short sleep duration (< 6 h). The global score on the PSQI was significantly higher in those participants with a lifetime diagnosis of substance use disorders, anxiety disorders, and affective disorders. Alcohol use disorders and affective disorders were significant predictors of sleep latency whereas anxiety and affective disorders were correlated with waking more often in the night/early morning. Nicotine dependence was associated with having trouble breathing, and alcohol use disorders and anxiety disorders with bad dreams. Alcohol use disorders are associated with poorer quality of sleep in this population and substance use disorders were associated with different aspects of sleep than anxiety and depressive disorders. These findings add to the understanding of the interactions between sleep and substance use, anxiety, and affective disorders in an understudied and underserved population.

HIV care and treatment of American Indians/Alaska natives with diagnosed HIV infection - 27 states and the District of Columbia, 2012.

The objective of this study was to measure linkage to care, retention in care, and suppressed viral load (VL) among American Indians/Alaska Natives (AIs/ANs) aged ≥13 years with diagnosed HIV infection. We used national HIV case surveillance data to measure linkage to care, defined as ≥1 CD4 or VL test ≤1 month after HIV diagnosis during 2013; retention in care, defined as ≥2 CD4 or VL tests ≥3 months apart during 2012; and suppressed VL, defined as <200 copies/mL at the most recent VL test during 2012. In 2013, 74.1% of AIs/ANs were linked to care. At year-end 2012, 46.9% of AIs/ANs were retained in care and 45.1% were virally suppressed. A lower percentage of females (41.3%), compared with males (46.5), were virally suppressed. By age group, the lowest percentage of virally suppressed AIs/ANs (37.5%) were aged 13-34 years. To improve individual health and to prevent HIV among AIs/ANs, outcomes must improve - particularly for female AIs/ANs and for AIs/ANs aged 13-34 years. Screening for HIV infection in accordance with Centers for Disease Control and Prevention's testing recommendations can lead to improvements along the continuum of HIV care.

American Indian and Alaska Native Cancer Patients' Perceptions of a Culturally Specific Patient Navigator Program.

Lack of access to care, funding limitations, cultural, and social barriers are challenges specific to tribal communities that have led to adverse cancer outcomes among American Indians/Alaska Natives (AI/AN). While the cancer navigator model has been shown to be effective in other underserved communities, it has not been widely implemented in Indian Country. We conducted in-depth interviews with 40 AI/AN patients at tribal clinics in Idaho and Oregon. We developed the survey instrument in partnership with community members to ensure a culturally appropriate semi-structured questionnaire. Questions explored barriers to accessing care, perceptions of the navigator program, satisfaction, and recommendations. AI/AN cancer patients reported physical, emotional, financial, and transportation barriers to care, but most did not feel there were any cultural barriers to receiving care. Navigator services most commonly used included decision making, referrals, transportation, scheduling appointments, and communication. Satisfaction with the program was high. Our study provides a template to develop a culturally appropriate survey instrument for use with an AI/AN population, which could be adapted for use with other indigenous patient populations. Although our sample was small, ourqualitative analysis facilitated a deeper understanding of the barriers faced by this population and how a navigator program may best address them. The results reveal the strengths and weakness of this program, and provide baseline patient satisfaction numbers which will allow future patient navigator programs to better create evaluation benchmarks.

NATIVE-It's Your Game: Adapting a Technology-Based Sexual Health Curriculum for American Indian and Alaska Native youth.

Sexually transmitted infection (STI) and birth rates among American Indian/Alaska Native (AI/AN) youth indicate a need for effective middle school HIV/STI and pregnancy prevention curricula to delay, or mitigate, the consequences of early sexual activity. While effective curricula exist, there is a dearth of curricula with content salient to AI/AN youth. Further, there is a lack of sexual health curricula that take advantage of the motivational appeal, reach, and fidelity of communication technology for this population, who are sophisticated technology users. We describe the adaptation process used to develop Native It's Your Game, a stand-alone 13-lesson Internet-based sexual health life-skills curriculum adapted from an existing promising sexual health curriculum, It's Your Game-Tech (IYG-Tech). The adaptation included three phases: (1) pre-adaptation needs assessment and IYG-Tech usability testing; (2) adaptation, including design document development, prototype programming, and alpha testing; and (3) post-adaption usability testing. Laboratory- and school-based tests with AI/AN middle school youth demonstrated high ratings on usability parameters. Youth rated the Native IYG lessons favorably in meeting the needs of AI/AN youth (54-86% agreement across lessons) and in comparison to other learning channels (57-100%) and rated the lessons as helpful in making better health choices (73-100%). Tribal stakeholders rated Native IYG favorably, and suggested it was culturally appropriate for AI/AN youth and suitable for implementation in tribal settings. Further efficacy testing is indicated for Native IYG, as a potential strategy to deliver HIV/STI and pregnancy prevention to traditionally underserved AI/AN middle school youth.

Homicide Among American Indians/Alaska Natives, 1999-2009: Implications for Public Health Interventions.

We determined estimates of homicide among American Indians/Alaska Natives (AI/ANs) compared with non-Hispanic white people to characterize disparities and improve AI/AN classification in incidence and mortality reporting. We linked 1999-2009 death certificate data with Indian Health Service (IHS) patient registration data to examine death rates from homicide among AI/AN and non-Hispanic white people. Our analysis focused primarily on residents of IHS Contract Health Service Delivery Area counties and excluded Hispanic people to avoid underestimation of incidence and mortality in AI/ANs and for consistency in our comparisons. We used age-adjusted death rates per 100,000 population and stratified our analyses by sex, age, and IHS region. Death rates per 100,000 population from homicide were four times higher among AI/ANs (rate = 12.1) than among white people (rate = 2.8). Homicide rates for AI/ANs were highest in the Southwest (25.6 and 6.9 for males and females, respectively) and in Alaska (17.7 and 10.3 for males and females, respectively). Disparities between AI/ANs and non-Hispanic white people were highest in the Northern Plains region among men (rate ratio [RR] = 9.8, 95% confidence interval [CI] 8.5, 11.3) and among those aged 25-44 years (RR59.0, 95% CI 7.5, 10.7) and 0-24 years (RR57.4, 95% CI 6.1, 8.9). Death rates from homicide among AI/ANs were higher than previously reported and varied by sex, age, and region. Violence prevention efforts involving a range of stakeholders are needed at the community level to address this important public health issue.

Impact of Violence and Relationship Abuse on Grades of American Indian/Alaska Native Undergraduate College Students.

Violence and relationship abuse are pervasive public health problems that have a range of negative effects, with exceptionally high prevalence among ethno-racial minority youth. This study assesses the prevalence of these types of violence among American Indian/Alaska Native (AI/AN) students and examines the impact of victimization on academic performance of AI/AN and non-AI/AN student populations using self-reported college health survey data. Results show that students who identified fully or partially as AI/AN reported markedly higher rates of all types of violence/abuse than did other students, and students who had experienced violence/abuse had lower grade point averages (GPAs) compared with those who had not. Recommendations for future research and direct practice with AI/AN students are discussed.

Acquired capability for suicide among individuals with American Indian/Alaska Native backgrounds within the military.

The present study observes a military sample across race to better understand suicide risk among American Indian/Alaska Native (AI/AN) individuals utilizing the Interpersonal Theory of Suicide. In a sample of 3,387 Army recruiters, multivariate analysis of variance was used to compare the means across race on acquired capability and pain tolerance. AI/AN individuals demonstrated higher levels of acquired capability for suicide (p = .056) and pain tolerance (p = .028). These findings indicate that acquired capability and pain tolerance are key elements involved in suicide risk among AI/AN individuals within the military.

The Design of a Multi-component Intervention to Promote Screening Mammography in an American Indian Community: The Native Women's Health Project.

BackgroundBreast cancer is an important public health issue among American Indian/Alaska Native (AI/AN) women in the US. This article describes the design and implementation of a culturally sensitive intervention to promote breast health among AI/AN women through a hybrid model that incorporates clinical and community-based approaches. This is one of the first studies using this model addressing breast cancer disparities among AI/AN populations in the US.MethodsThe Theory of Planned Behavior was used as the guiding framework of the intervention and Community Based Participatory Research was the primary vehicle for the intervention planning and implementation. Three preliminary studies took place that aimed to identify qualitatively and quantitatively what deterred or encouraged AI women to get past or future mammograms. The research results were shared with community members who, through a prioritization process, identified the theoretical focus of the intervention and its corresponding activities. The priority population consisted of AI women ages 40–74, with no recent mammogram, and no breast cancer history.ResultsThe intervention centered on the promotion of social modeling and physician recommendation. The main corresponding activities included enhancing patient-physician communication about screening mammography through a structured dialogue, receipt of a breast cancer brochure, participation in an inter-generational discussion group, and a congratulatory bracelet upon receipt of a mammogram. Environmental and policy related changes also were developed.ConclusionCreating a theory-based, culturally-sensitive intervention through tribal participatory research is a challenging approach towards eliminating breast cancer disparities among hard-to-reach populations.

Trends and Patterns of Late and Unstaged Lung, Colorectal, Female Breast, and Prostate Cancers among American Indians in the Northern Plains, 2002-2009.

We investigated incidence and staging patterns of prostate, female breast, lung, and colorectal cancer among American Indians/Alaska Natives (AI/ANs) and non-Hispanic Whites (NHWs) in the Northern Plains. Cancer registry data (2002-2009) from Nebraska, North Dakota, and South Dakota were analyzed. Incidence rates were calculated and multivariate logistic regression analyses identified factors associated with unstaged versus staged and late-stage cancer cases versus early. The incidence rate was higher among AI/ANs than NHWs for lung cancer (92.2 vs. 60.6 per 100,000). Compared with NHWs, AI/ANs were 2.0 times more likely to receive an unstaged diagnosis and 1.2 times more likely to receive a late-stage diagnosis. AI/ANs were significantly more likely than NHWs to receive an unstaged diagnosis. Increased efforts are needed to reduce unstaged and late-stage diagnoses among Northern Plains AIs. Efforts to promote early detection of cancer should target younger AI/ANs.

Clinicians' Implicit and Explicit Attitudes about Weight and Race and Treatment Approaches to Overweight for American Indian Children.

Obesity is one of the most serious health problems among American Indian/Alaska Native (AI/AN) children. We investigated Indian Health Service (IHS) primary care providers' implicit and explicit attitudes about weight and race and their association with treatment approaches to overweight in children. We conducted an online survey of long-term primary care clinicians in two western regions of the IHS. We used the existing Weight Attitude Implicit Association Test (IAT) and developed a new Native American Attitude IAT to measure implicit attitudes. Explicit attitudes about weight and race were assessed through self-report. We assessed self-rated treatment approaches to childhood overweight. We used linear regression models to evaluate the association of attitudes about weight and race with treatment approaches. Our sample included 75 clinicians (56% response rate) who, on average, saw 74 patients per week. Fifty-five percent of clinicians reported that 30-60% of their child and adolescent patients were overweight or obese, and 25% of clinicians reported that 60-100% of their patients were overweight or obese. We found strong implicit bias favoring thin people (Cohen's d=1.44) and weak implicit bias favoring whites (Cohen's d=0.35). We found no association between implicit or explicit bias scores and self-reported treatment of childhood overweight. Continuing education on obesity was associated with self-rated success and competence in weight management. Weight and race bias exists among long-term IHS clinicians, but may not influence treatment approaches for overweight AI/AN children. Further research should assess the effect of clinicians' attitudes on real-world weight management.

Implementing participatory research with an urban American Indian community: Lessons learned

Objective: Participatory research has proven an effective method for improving health equity among American Indians/Alaska Natives (AI/ANs) by addressing power imbalances between communities and researchers, incorporating community knowledge and theory, ensuring mutual benefit and improving community capacity and programme sustainability. However, few studies have examined the implementation of these methods with urban Indian (UI) communities, a growing population currently comprising 71% of AI/ANs. This paper describes the experiences of two academic researchers (one a Native doctoral student and another a White assistant professor) who sought to engage in participatory research with an UI community in Maryland. Method: The methodology employed was a literature review of Indigenous participatory research methods that aimed to inform the work of a youth-led project, and a reflexive case-study analysis. Results: Researchers discuss the social, structural and political inequalities that challenged their ability to engage in this process and identify three lessons learned associated with conducting participatory research with this population: logistics and recruitment, identifying the constraints and/or competing priorities of the community, and the importance of reflexivity and communication throughout the process. In an epilogue, the researchers highlight and reflect upon how they have since applied these lessons to strengthen their relationship with the community, yielding new and mutually beneficial participatory research projects. Conclusion: The findings presented advance research on participatory methodologies with UI communities and call for increased economic and political support of and long-term commitment to UI organisations to address the structural inequalities underpinning existing health inequities.

Preventing alcohol-exposed pregnancy among an American Indian/Alaska Native population: effect of a screening, brief intervention, and referral to treatment intervention.

Fetal alcohol spectrum disorders are the result of alcohol-exposed pregnancies (AEP) and believed to be the leading known cause of developmental disabilities in the United States. Our objective was to determine whether a culturally targeted Screening, Brief Intervention, and Referral to Treatment (SBIRT) intervention may reduce risky drinking and vulnerability to AEP among American Indian/Alaska Native (AIAN) women in Southern California. Southern California AIAN women of childbearing age who completed a survey including questions regarding alcohol consumption and contraceptive use were randomized into intervention or treatment as usual groups where the former group completed an online SBIRT intervention, and were followed up at 1, 3, and 6 months postintervention. Of 263 women recruited and 247 with follow-up data, one-third were at high risk of having an AEP at baseline. Both treatment groups decreased self-reported risky drinking behavior (drinks per week, p<0.001; frequency of heavy episodic [binge] drinking episodes per 2weeks, p=0.017 and risk of AEP p<0.001 at 6 months postintervention) in the follow-up period. There was no difference between treatment groups. Baseline factors associated with decreased risk of an AEP at follow-up included the perception that other women in their peer group consumed a greater number of drinks per week, having reported a greater number of binge episodes in the past 2weeks, and depression/impaired functionality. Participation in assessment alone may have been sufficient to encourage behavioral change even without the web-based SBIRT intervention. Randomization to the SBIRT did not result in a significantly different change in risky drinking behaviors. The importance of perception of other women's drinking and one's own depression/functionality may have implications for future interventions.

Racial discrimination's influence on smoking rates among American Indian Alaska Native two-spirit individuals: does pain play a role?

High rates of racial discrimination and non-ceremonial tobacco smoking exist among American Indian/Alaska Native (AIAN) Two-Spirit/LGBT (Lesbian, Gay, Bisexual, Transgender) populations. The authors examined whether or not pain mediates between racial discrimination and smoking among Two-Spirits. Two-Spirit adults (n=447) from seven urban U.S. locations were surveyed during the HONOR project. The Indigenist stress coping model was used as framework in which to conduct descriptive, bivariate and regression analyses. A majority of the participants reported smoking (45.2%) and pain (57%). Pain was found to mediate the association between racial discrimination and smoking. Racial discrimination appears to be a significant factor influencing tobacco smoking and health behaviors within Two-Spirit populations. Effective tobacco cessation and/or prevention planning for Two-Spirits and others who experience frequent racial discrimination, stress, and trauma should also consider the influence of pain. Pain may serve as the embodiment of discrimination, and this possibility requires future research

Lung Cancer Deaths Among American Indians and Alaska Natives, 1990–2009

We examined regional differences in lung cancer among American Indians/Alaska Natives (AI/ANs) using linked data sets to minimize racial misclassification. On the basis of federal lung cancer incidence data for 1999 to 2009 and deaths for 1990 to 2009 linked with Indian Health Service (IHS) registration records, we calculated age-adjusted incidence and death rates for non-Hispanic AI/AN and White persons by IHS region, focusing on Contract Health Service Delivery Area (CHSDA) counties. We correlated death rates with cigarette smoking prevalence and calculated mortality-to-incidence ratios. Lung cancer death rates among AI/AN persons in CHSDA counties varied across IHS regions, from 94.0 per 100,000 in the Northern Plains to 15.2 in the Southwest, reflecting the strong correlation between smoking and lung cancer. For every 100 lung cancers diagnosed, there were 6 more deaths among AI/AN persons than among White persons. Lung cancer death rates began to decline in 1997 among AI/AN men and are still increasing among AI/AN women. Comparison of regional lung cancer death rates between AI/AN and White populations indicates disparities in tobacco control and prevention interventions. Efforts should be made to ensure that AI/AN persons receive equal benefit from current and emerging lung cancer prevention and control interventions.

Breast Cancer Mortality Among American Indian and Alaska Native Women, 1990–2009

We compared breast cancer death rates and mortality trends among American Indian/Alaska Native (AI/AN) and White women using data for which racial misclassification was minimized. We used breast cancer deaths and cases linked to Indian Health Service (IHS) data to calculate age-adjusted rates and 95% confidence intervals (CIs) by IHS-designated regions from 1990 to 2009 for AI/AN and White women; Hispanics were excluded. Mortality-to-incidence ratios (MIR) were calculated for 1999 to 2009 as a proxy for prognosis after diagnosis. Overall, the breast cancer death rate was lower in AI/AN women (21.6 per 100,000) than in White women (26.5). However, rates in AI/ANs were higher than rates in Whites for ages 40 to 49 years in the Alaska region, and ages 65 years and older in the Southern Plains region. White death rates significantly decreased (annual percent change [APC] = -2.1; 95% CI = -2.3, -2.0), but regional and overall AI/AN rates were unchanged (APC = 0.9; 95% CI = 0.1, 1.7). AI/AN women had higher MIRs than White women. There has been no improvement in death rates among AI/AN women. Targeted screening and timely, high-quality treatment are needed to reduce mortality from breast cancer in AI/AN women.

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

We describe the relative burden of alcohol-attributable death among American Indians/Alaska Natives (AI/ANs) in the United States. 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. 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). Proven strategies that reduce alcohol consumption and make the environment safer for excessive drinkers should be further implemented in AI/AN communities.

Encephalitis-associated hospitalizations among American Indians and Alaska Natives.

Encephalitis produces considerable morbidity in the United States, but morbidity rates among American Indian/Alaska Native (AI/AN) people have not been described. Hospitalization records listing an encephalitis diagnosis were analyzed by using Indian Health Service direct/contract inpatient data. For 1998-2010, there were 436 encephalitis-associated hospitalizations among AI/AN people, an average annual age-adjusted hospitalization rate of 3.1/100,000 population. The rate for infants (11.9) was more than double that for any other age group. Death occurred for 4.1% of hospitalizations. Consistent with reports for the general U.S. population, the rate was high among infants and most (53.9%) hospitalizations were of unexplained etiology. The average annual rate during the study period appeared lower than for the general U.S. population, due particularly to lower rates in the elderly. Future community-based surveillance and mortality studies are needed to confirm these findings and examine reasons underlying the low rates of encephalitis in AI/AN people.

Self-reported versus administrative identification of American Indian and Alaska Native arrestees: effects on relative estimates of illicit drug use and alcohol abuse.

Arrestee Drug Abuse Monitoring program data were used to consider the effects of two methods of racial classification upon estimates of illicit drug use and alcohol abuse among American Indian/Alaska Native (AI/AN) arrestees. Overall, compared to arrestees who self-identified as Black, White, Asian/Pacific Islander, or Hispanic, arrestees self-identifying as AI/AN were most likely to be identified administratively as something other than AI/AN. Results of 'difference of difference' analyses indicate that differences in estimates of AI/AN versus non-AI/AN arrestees' illicit drug use and alcohol abuse were much more extreme when identification was based on administrative records than when based upon arrestees' self-reports.
