RESUMO

OBJECTIVE: The sole prospective longitudinal study of children with either chronic suppurative lung disease (CSLD) or bronchiectasis published in the current era was limited to a single center. We sought to extend this study by evaluating the longer-term clinical and lung function outcomes and their associated risk factors in Indigenous children of adolescents from Australia, Alaska, and New Zealand who participated in our previous CSLD or bronchiectasis studies during 2004-2010. METHODS: Between 2015 and 2018, we evaluated 131 out of 180 (72.8%) children of adolescents from the original studies at a single follow-up visit. We administered standardized questionnaires, reviewed medical records, undertook clinical examinations, performed spirometry, and scored available chest computed tomography scans. RESULTS: Participants were seen at a mean age of 12.3 years (standard deviation: 2.6) and a median of 9.0 years (range: 5.0-13.0) after their original recruitment. With increasing age, rates of acute lower respiratory infections (ALRI) declined, while lung function was mostly within population norms (median forced expiry volume in one-second = 90% predicted, interquartile range [IQR]: 81-105; forced vital capacity [FVC] = 98% predicted, IQR: 85-114). However, 43 out of 111 (38.7%) reported chronic cough episodes. Their overall global rating judged by symptoms, including ALRI frequency, examination findings, and spirometry was well (20.3%), stable (43.9%), or improved (35.8%). Multivariable regression identified household tobacco exposure and age at first ALRI-episode as independent risk factors associated with lower FVC% predicted values. CONCLUSION: Under our clinical care, the respiratory outcomes in late childhood or early adolescence are encouraging for these patient populations at high-risk of premature mortality. Prospective studies to further inform management throughout the life course into adulthood are now needed.

RESUMO

Alaska Native (AN) people have among the highest rates of colorectal cancer (CRC) recorded globally. Preventing CRC is an important health priority of AN tribal health leaders and communities. Lifestyle and genetic risk and protective factors for CRC among AN people remain understudied. We have been working to establish a tribally led, community-based, comprehensive investigation of lifestyle and genetic risk and protective factors for CRC among AN people. We describe the process of initiating this research study, including conversations with key tribal health system staff. We discuss themes that arose during these conversations and literature review and describe how those themes were used during the study design and protocol development phase. This description is intended to provide guidance to other researchers working to establish community-based studies of cancer risk, particularly among tribal communities.

RESUMO

PURPOSE: This study examined the time from breast cancer diagnosis to initiation of treatment among Alaska Native (AN) women. We evaluated the impact of age, cancer stage, and rural/urban residence at diagnosis. METHODS: We evaluated characteristics of women recorded in the Alaska Native Tumor Registry who received a first diagnosis of breast cancer between 2009 and 2013. Median time from diagnosis to treatment was assessed. Associations of demographic and clinical characteristics with timely initiation of treatment were evaluated using logistic regression and Cox proportional hazards models. RESULTS: Two hundred seventy-eight (278) AN women were diagnosed with invasive breast cancer in years 2009-2013. Mean age at diagnosis was 56.8 years (SD = 13.0). The median time from diagnosis to initiation of treatment was 23 days (P < .05) with most (94.6%, n = 263) meeting the ≤60-day guideline target. Time to treatment was not associated with rural/urban residence, age, or stage at cancer diagnosis. CONCLUSION: These findings indicate that most AN women diagnosed with breast cancer within the AN Tribal Health System receive timely treatment after diagnosis.

RESUMO

Dermatology is greatly understudied in the American Indian/Alaska Native (AIAN) population. This topic deserves attention in light of the changing demographics of the United States and the healthcare disparities faced by AIAN, including access to dermatologic care. In this review, we discuss disorders that are more prevalent or otherwise important in the AIAN population, such as cutaneous malignancies, photodermatoses, acanthosis nigricans, connective tissue disorders, cutaneous infections, hypertrophic scar formation, and Heck's disease. We aim to provide an updated review and increase awareness of the dermatologic needs of the AIAN population.

RESUMO

INTRODUCTION: Among US men, prostate cancer is the leading malignancy diagnosed and the second leading cause of cancer death. Disparities in cancer screening rates exist between American Indians/Alaska Natives and other racial/ethnic groups. Our study objectives were to examine prostate screening at 5 time points over a 12-year period among American Indian/Alaska Native men aged 50 to 75 years, and to compare their screening rates to African American men and white men in the same age group. METHODS: We analyzed Health and Retirement Study data for 1996, 1998, 2000, 2004, and 2008. Prostate screening was measured by self-report of receipt of a prostate examination within the previous 2 years. Age-adjusted prevalence was estimated for each year. We used regression with generalized estimating equations to compare prostate screening prevalence by year and race. RESULTS: Our analytic sample included 119 American Indian/Alaska Native men (n = 333 observations), 1,359 African American men (n = 3,704 observations), and 8,226 white men (n = 24,292 observations). From 1996 to 2008, prostate screening rates changed for each group: from 57.0% to 55.7% among American Indians/Alaska Natives, from 62.0% to 71.2% among African Americans, and from 68.6% to 71.3% among whites. Although the disparity between whites and African Americans shrank over time, it was virtually unchanged between whites and American Indians/Alaska Natives. CONCLUSION: As of 2008, American Indians/Alaska Natives were less likely than African Americans and whites to report a prostate examination within the previous 2 years. Prevalence trends indicated a modest increase in prostate cancer screening among African Americans and whites, while rates remained substantially lower for American Indians/Alaska Natives.

RESUMO

INTRODUCTION: Smoking-related disparities continue to be a public health problem among American Indian/Alaska Native (AI/AN) population groups and data documenting the health burden of smoking in this population are sparse. The purpose of this study was to assess mortality attributable to cigarette smoking among AI/AN adults relative to non-Hispanic white adults (whites) by calculating and comparing smoking-attributable fractions and mortality. METHODS: Smoking-attributable fractions and mortality among AI/ANs (n=1.63 million AI/ANs) and whites were calculated for people living in 637 Indian Health Service Contract Health Service Delivery Area counties in the U.S., from mortality data collected during 2001-2009. Differences in smoking-attributable mortality between AI/ANs and whites for five major causes of smoking-related deaths were examined. All data analyses were carried out in 2013-2014. RESULTS: Overall, from 2001 to 2009, age-adjusted death rates, smoking-attributable fractions, and smoking-attributable mortality for all-cause mortality were higher among AI/ANs than among whites for adult men and women aged ≥35 years. Smoking caused 21% of ischemic heart disease, 15% of other heart disease, and 17% of stroke deaths in AI/AN men, compared with 15%, 10%, and 9%, respectively, for white men. Among AI/AN women, smoking caused 18% of ischemic heart disease deaths, 13% of other heart diseases deaths, and 20% of stroke deaths, compared with 9%, 7%, and 10%, respectively, among white women. CONCLUSIONS: These findings underscore the need for comprehensive tobacco control and prevention efforts that can effectively reach and impact the AI/AN population to prevent and reduce smoking.

RESUMO

BACKGROUND: Little has been reported regarding patterns of oncologic care in American Indian/Alaska Natives (AI/AN). Observed worse survival has been attributed to later-stage presentation. We aimed to evaluate racial differences in cancer-directed therapy and hospice care utilization in AI/ANs and non-Hispanic whites (NHW) with metastatic cancer. METHODS: The linked Surveillance, Epidemiology, and End Results (SEER)-Medicare claims database was accessed for AI/AN and NHW metastatic-cancer cases diagnosed between 2001 and 2007. Utilization of cancer-directed therapy (surgery, radiation, and/or chemotherapy) and/or hospice services was compared between AI/ANs and NHWs. Minimally adjusted (age, sex, diagnosis year) and fully-adjusted (also Klabunde comorbidity score, sociodemographic factors) regression models were used to estimate odds (OR) and hazard ratios (HR) for receipt of care. RESULTS: AI/ANs were younger, more likely to reside in the West, be unmarried, have lower income, and live in a nonurban setting than NHWs. Fewer AI/ANs received any cancer-directed therapy (57% vs. 61% NHWs) within 3 months of diagnosis; sociodemographic factors accounted for much of this difference [fully-adjusted HR, 0.94; 95% confidence interval (CI), 0.83-1.08]. We noted differences in hospice utilization between AI/ANs (52%) and NHWs (61%). A significant difference in hospice utilization remained after adjustment for sociodemographics (OR, 0.78; 95% CI, 0.61-0.99). CONCLUSION: Observed absolute differences in care for AI/ANs and NHWs with metastatic cancer were largely accounted for by adjusting for socioeconomics, comorbidities, and demographic factors. A significant association between race and hospice utilization was noted. IMPACT: Efforts to improve metastatic-cancer care should focus on socioeconomic barriers and investigate the observed disparity in receipt of hospice services.

RESUMO

OBJECTIVE: To determine the relationship between depression and diabetes management among urban American Indians/Alaska Natives (AI/ANs). DESIGN: Retrospective, cross-sectional analysis of medical records. SETTING: 33 Urban Indian Health Organizations that participated in the Indian Health Service Diabetes Care and Outcomes Audit. PATIENTS: 3,741 AI/AN patient records. MAIN OUTCOME MEASURES: Diabetes management outcomes, including HbA1c, smoking, BMI, systolic blood pressure, creatinine, total cholesterol, and receipt of preventive services. RESULTS: Individuals with depression and diabetes were 1.5 times more likely to smoke than individuals with diabetes but without depression (OR=1.51; 95% Cl: 1.23, 1.86), controlling for age, sex, and facility. After adjustment, the geometric mean BMI in diabetes patients with depression was 3% higher than in patients without depression (ß=.034; 95% CI: .011, .057). CONCLUSIONS: Urban AI/ANs with diabetes and depression are more likely to smoke and have higher BMI than those with diabetes but without depression. These findings inform programmatic efforts to address the care of patients with both depression and diabetes.

RESUMO

BACKGROUND: American Indians and Alaska Natives (AI/ANs) have high rates of tobacco use compared to the general population. AI/ANs also have elevated rates of psychiatric and substance use disorders associated with nicotine dependence. However, very few studies have examined the comorbidity between nicotine dependence and psychiatric and substance use disorders within this population. METHODS: This study analyzes the comorbidity of lifetime nicotine dependence with both current and lifetime psychiatric disorders and substance use disorders in a nationally representative sample of 701 AI/AN women and men. RESULTS: Using 95% confidence interval testing, lifetime nicotine dependence (29.5%) was associated with all main diagnostic categories (any mood disorder, any anxiety disorder, any personality disorder, any alcohol use disorder, and any drug use disorder) both at the lifetime level and current (12-month) level. Of the lifetime disorders, the strongest associations were with psychosis and drug dependence. For (current) 12-month disorders, the strongest associations were with alcohol dependence and drug dependence. Differences were noted between genders regarding personality disorders. CONCLUSIONS: Culturally appropriate tobacco screening, prevention, and treatment curricula for adult AI/ANs with dual diagnoses are recommended. Understanding historically based factors that may contribute to psychiatric illness and substance use disorders may assist in more effective nicotine treatments for AI/ANs.

RESUMO

BACKGROUND: Despite recommendations for cancer screening for breast and colorectal cancer among the Medicare population, preventive screenings rates are often lower among vulnerable populations such as the small but rapidly growing older American Indian and Alaska Native (AIAN) population. This study seeks to identify potential disparities in the availability of screening services, distance to care, and the utilization of cancer screening services for Medicare beneficiaries residing in areas with a higher concentration of AIAN populations. METHODS: Using the county (n =3,225) as the level of analysis, we conducted a cross-sectional analysis of RTI International's Spatial Impact Factor Data (2012) to determine the level of disparities for AIAN individuals. The outcomes of interest include: the presence of health care facilities in the county, the average distance in miles to the closest provider of mammography and colonoscopy (analyzed separately) and utilization of screening services (percent of adults aged 65 and older screened by county). RESULTS: Counties with higher concentrations of AIAN individuals had greater disparities in access and utilization of cancer screening services. Even after adjusting for income, education, state of residence, population 65 and older and rurality, areas with higher levels of AIAN individuals were more likely to see disparities with regard to health care services related to mammograms (p ≤ .05; longer distance, lower screening) and colonoscopies (p ≤ .05; longer distance, lower screening). CONCLUSIONS: These findings provide evidence of a gap in service availability, utilization and access facing areas with higher levels of AIAN individuals throughout the US. Without adequate resources in place, these areas will continue to have less access to services and poorer health which will be accelerated as the population of older adults grows.

RESUMO

OBJECTIVES: We examined regional differences in lung cancer among American Indians/Alaska Natives (AI/ANs) using linked data sets to minimize racial misclassification. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

RESUMO

OBJECTIVES: We evaluated the racial misclassification of American Indians and Alaska Natives (AI/ANs) in cancer incidence and all-cause mortality data by Indian Health Service (IHS) Contract Health Service Delivery Area (CHSDA). METHODS: We evaluated data from 3 sources: IHS-National Vital Statistics System (NVSS), IHS-National Program of Cancer Registries (NPCR)/Surveillance, Epidemiology and End Results (SEER) program, and National Longitudinal Mortality Study (NLMS). We calculated, within each data source, the sensitivity and classification ratios by sex, IHS region, and urban-rural classification by CHSDA county. RESULTS: Sensitivity was significantly greater in CHSDA counties (IHS-NVSS: 83.6%; IHS-NPCR/SEER: 77.6%; NLMS: 68.8%) than non-CHSDA counties (IHS-NVSS: 54.8%; IHS-NPCR/SEER: 39.0%; NLMS: 28.3%). Classification ratios indicated less misclassification in CHSDA counties (IHS-NVSS: 1.20%; IHS-NPCR/SEER: 1.29%; NLMS: 1.18%) than non-CHSDA counties (IHS-NVSS: 1.82%; IHS-NPCR/SEER: 2.56%; NLMS: 1.81%). Race misclassification was less in rural counties and in regions with the greatest concentrations of AI/AN persons (Alaska, Southwest, and Northern Plains). CONCLUSIONS: Limiting presentation and analysis to CHSDA counties helped mitigate the effects of race misclassification of AI/AN persons, although a portion of the population was excluded.

RESUMO

OBJECTIVES: We analyzed cervical cancer incidence and mortality data in American Indian and Alaska Native (AI/AN) women compared with women of other races. METHODS: We improved identification of AI/AN race, cervical cancer incidence, and mortality data using Indian Health Service (IHS) patient records; our analyses focused on residents of IHS Contract Health Service Delivery Area (CHSDA) counties. Age-adjusted incidence and death rates were calculated for AI/AN and White women from 1999 to 2009. RESULTS: AI/AN women in CHSDA counties had a death rate from cervical cancer of 4.2, which was nearly twice the rate in White women (2.0; rate ratio [RR] = 2.11). AI/AN women also had higher incidence rates of cervical cancer compared with White women (11.0 vs 7.1; RR = 1.55) and were more often diagnosed with later-stage disease (RR = 1.84 for regional stage and RR = 1.74 for distant stage). Death rates decreased for AI/AN women from 1990 to 1993 (-25.8%/year) and remained stable thereafter. CONCLUSIONS: Although rates decreased over time, AI/AN women had disproportionately higher cervical cancer incidence and mortality. The persistently higher rates among AI/AN women compared with White women require continued improvements in identifying and treating cervical cancer and precancerous lesions.

RESUMO

OBJECTIVES: We describe rates and trends in kidney cancer incidence and mortality and identify disparities between American Indian/Alaska Native (AI/AN) and White populations. METHODS: To improve identification of AI/AN race, incidence and mortality data were linked with Indian Health Service (IHS) patient records. Analysis focused on residents of IHS Contract Health Service Delivery Area counties; Hispanics were excluded. We calculated age-adjusted kidney cancer incidence (2001-2009) and death rates (1990-2009) by sex, age, and IHS region. RESULTS: AI/AN persons have a 1.6 times higher kidney cancer incidence and a 1.9 times higher kidney cancer death rate than Whites. Despite a significant decline in kidney cancer death rates for Whites (annual percentage change [APC] = -0.3; 95% confidence interval [CI] = -0.5, 0.0), death rates for AI/AN persons remained stable (APC = 0.4; 95% CI = -0.7, 1.5). Kidney cancer incidence rates rose more rapidly for AI/AN persons (APC = 3.5; 95% CI = 1.2, 5.8) than for Whites (APC = 2.1; 95% CI = 1.4, 2.8). CONCLUSIONS: AI/AN individuals have greater risk of developing and dying of kidney cancers. Incidence rates have increased faster in AI/AN populations than in Whites. Death rates have decreased slightly in Whites but remained stable in AI/AN populations. Racial disparities in kidney cancer are widening.

RESUMO

OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVES: We characterized estimates of colorectal cancer (CRC) in American Indians/Alaska Natives (AI/ANs) compared with Whites using a linkage methodology to improve AI/AN classification in incidence and mortality data. METHODS: We linked incidence and mortality data to Indian Health Service enrollment records. Our analyses were restricted to Contract Health Services Delivery Area counties. We analyzed death and incidence rates of CRC for AI/AN persons and Whites by 6 regions from 1999 to 2009. Trends were described using linear modeling. RESULTS: The AI/AN colorectal cancer incidence was 21% higher and mortality 39% higher than in Whites. Although incidence and mortality significantly declined among Whites, AI/AN incidence did not change significantly, and mortality declined only in the Northern Plains. AI/AN persons had a higher incidence of CRC than Whites in all ages and were more often diagnosed with late stage CRC than Whites. CONCLUSIONS: Compared with Whites, AI/AN individuals in many regions had a higher burden of CRC and stable or increasing CRC mortality. An understanding of the factors driving these regional disparities could offer critical insights for prevention and control programs.

RESUMO

OBJECTIVES: We linked databases to improve identification of American Indians/Alaska Natives (AI/ANs) in determining prostate cancer death and incidence rates. METHODS: We linked prostate cancer mortality and incidence data with Indian Health Service (IHS) patient records; analyses focused on residents of IHS Contract Health Service Delivery Area (CHSDA) counties. We calculated age-adjusted incidence and death rates for AI/AN and White men for 1999 to 2009; men of Hispanic origin were excluded. RESULTS: Prostate cancer death rates were higher for AI/AN men than for White men. Death rates declined for White men (-3.0% per year) but not for AI/AN men. AI/AN men had lower prostate cancer incidence rates than White men. Incidence rates declined among Whites (-2.2% per year) and AI/ANs (-1.9% per year). CONCLUSIONS: AI/AN men had higher prostate cancer death rates and lower prostate cancer incidence rates than White men. Disparities in accessing health care could contribute to mortality differences, and incidence differences could be related to lower prostate-specific antigen testing rates among AI/AN men.

RESUMO

OBJECTIVES: We used improved data on American Indian and Alaska Native (AI/AN) ancestry to provide an updated and comprehensive description of cancer mortality and incidence among AI/AN populations from 1990 to 2009. METHODS: We linked the National Death Index and central cancer registry records independently to the Indian Health Service (IHS) patient registration database to improve identification of AI/AN persons in cancer mortality and incidence data, respectively. Analyses were restricted to non-Hispanic persons residing in Contract Health Service Delivery Area counties in 6 geographic regions of the United States. We compared age-adjusted mortality and incidence rates for AI/AN populations with White populations using rate ratios and mortality-to-incidence ratios. Trends were described using joinpoint analysis. RESULTS: Cancer mortality and incidence rates for AI/AN persons compared with Whites varied by region and type of cancer. Trends in death rates showed that greater progress in cancer control was achieved for White populations compared with AI/AN populations over the last 2 decades. CONCLUSIONS: Spatial variations in mortality and incidence by type of cancer demonstrated both persistent and emerging challenges for cancer control in AI/AN populations.

RESUMO

OBJECTIVES: We examined geographic differences and trends in incidence and mortality of ovarian and uterine cancer in American Indian/Alaska Native (AI/AN) women. METHODS: We linked mortality data (1990-2009) and incidence data (1999-2009) to Indian Health Service (IHS) records. Death (and incidence) rates for ovarian and uterine cancer were examined for AI/AN and White women; Hispanics were excluded. Analyses focused on Contract Health Service Delivery Area (CHSDA) counties. RESULTS: AI/AN and White women had similar ovarian and uterine cancer death rates. Ovarian and uterine cancer incidence and death rates were higher for AI/ANs residing in CHSDA counties than for all US counties. We also observed geographic differences, regardless of CHSDA residence, in ovarian and uterine cancer incidence and death rates in AI/AN women by IHS region; Pacific Coast and Southern Plains women had higher ovarian cancer death rates and Northern Plains women had higher uterine cancer death rates. CONCLUSIONS: Regional differences in the incidence and mortality of ovarian and uterine cancers among AI/AN women in the United States were significant. More research among correctly classified AI/AN women is needed to understand these differences.
