Proceedings of the Alaska-Russia Native Peoples Health and Social Issues Conference. May 1992, Alaska.

An Alaska-Russia Native People's Health and Social Issues Conference, sponsored by the Alaska Department of Health and Social Services, the Alaska Native Foundation, the University of Anchorage Institute for Circumpolar Health Studies, the International Scientific Center "ARTIKA" (Magadan, Russia), the Associations of Native People of Chukotka and Kolyma, and the Magadan Native Association, was held in Wasilla, Alaska in May, 1992. The conference brought together Native people, primarily health and social services workers, to discuss differences and similarities in issues and approaches, and to lay the foundation for future collaboration. The primary participants came mostly from rural villages and small regional cities, and represented Native Health Corporations, Native Associations, and villages. Additional participants came from the University of Alaska, the Alaska Department of Health and Social Services, the Indian Health Service, the Magadan Health Department, the Inuit Circumpolar Conference, and the International Union for Circumpolar Health. A Total of 39 people participated, including: eight Russian Natives (Chukchi, Even, and Siberian Yup'ik); three non-Native Russians; 18 Alaska Natives (Aleut, Athabaskan, Inupiat, Siberian Yup'ik, Yup'ik); nine non-Native Alaskans; one Canadian. The issues discussed in individual and panel presentations, and in small groups, included history, demography, settlement patterns, the cash and subsistence economies, mental and physical health (epidemiology, etiology, treatment and prevention), education, governance, culture and language. As the conference participants came to know each other better, the discussions became increasingly open, and, particularly around shared feelings of cultural oppression and loss, emotional.(ABSTRACT TRUNCATED AT 250 WORDS)

Racial differences in birthweight-specific neonatal mortality in Alaska: 1987-1996.

OBJECTIVES: This study compared the neonatal mortality in the Alaska Native and non-native (primarily white) population in Alaska for a 10-year period (1987-1996). METHODS: Natality, mortality, and cause of death data were obtained from the State of Alaska's Bureau of Vital Statistics (BVS). Birthweight-specific and preventable birthweight-specific mortality were analyzed for babies < 1500 grams, 1500-2499 grams, and > or = 2500 grams birthweight. RESULTS: The low birthweight (LBW) and very low birthweight (VLBW) rates were similar for the Alaska Native and non-native populations. The neonatal mortality rate for the Alaska Native population was higher than for the non-native population (6.4 per 1,000 live births for Alaska Native vs. 4.1 for non-native for 1987-1991; 5.5 for Alaska Native vs. 3.5 for non-native for 1992-1996). Birthweight-specific mortality was higher in the Alaska Native population for all birthweight groups. The exclusion of non-preventable conditions accentuated the differences in mortality rates between the Alaska Native and non-native population for infants < 2500 grams birthweight. CONCLUSION: The higher neonatal mortality in the Alaska Native population is associated with a higher overall and preventable birthweight-specific neonatal mortality. The differences are therefore likely to reflect differences in access to and quality of perinatal care.

A brief discussion of the development of Native owned health provider agencies in Alaska within the context of anticipated health and systems issues.

The Self-Determination Act brought about an explosive growth of tribally run programs in Alaska during the 1970s at the same time that the Alaska Native Claims Settlement Act was being implemented. Tribes demonstrated great creativity in blending IHS with other sources of funds to develop more effective and more acceptable delivery of services to their people. Further, the tribes in Alaska have demonstrated great aptitude in developing effective lobbying techniques with the United States Congress, such that they have actually been able to increase their funding base beyond what was assumed at the time of takeover from the IHS. However, several problems loom on the horizon. First, there is the problem of cost shifting within the IHS which contains the potential that tribes opting not to take advantage of the Self-Determination Act may be victimized by those who do. Second, there is the problem of too few resources to serve too many patients, which from time to time, propels the Indian Health Service toward an attempt to change the rules with respect to eligibility for services. Finally, the ability of the Indian Health Service (and by extension, its contract tribes) to provide an adequate level of services to American Indian and Alaska Native clients is being dramatically eroded by the same inflationary forces that are driving the larger system of health care in the United States toward the brink of disaster.

Alaska telemedicine: growth through collaboration.

The last thirty years have brought the introduction and expansion of telecommunications to rural and remote Alaska. The intellectual and financial investment of earlier projects, the more recent AFHCAN Project and the Universal Service Administrative Company Rural Health Care Division (RHCD) has sparked a new era in telemedicine and telecommunication across Alaska. This spark has been flamed by the dedication and collaboration of leaders at he highest levels of organizations such as: AFHCAN member organizations, AFHCAN Office, Alaska Clinical Engineering Services, Alaska Federal Health Care Partnership, Alaska Federal Health Care Partnership Office, Alaska Native health Board, Alaska Native Tribal health Consortium, Alaska Telehealth Advisory Council, AT&T Alascom, GCI Inc., Health care providers throughout the state of Alaska, Indian Health Service, U.S. Department of Health and Human Services, Office of U.S. Senator Ted Steens, State of Alaska, U.S. Department of Homeland Security--United States Coast Guard, United States Department of Agriculture, United States Department of Defense--Air Force and Army, United States Department of Veterans Affairs, University of Alaska, and University of Alaska Anchorage. Alaska now has one of the largest telemedicine programs in the world. As Alaska moves system now in place become self-sustaining, and 2) collaborating with all stakeholders in promoting the growth of an integrated, state-wide telemedicine network.

The epidemiology of invasive pneumococcal disease in Alaska, 1986-1990--ethnic differences and opportunities for prevention.

To assess prevention strategies for pneumococcal disease in Alaska, prospective surveillance during 1986-1990 identified 672 invasive pneumococcal infections, including 315 among Alaska Natives. Age-adjusted annual incidence was 74 per 100,000 for Alaska Natives and 16 per 100,000 for nonnatives. The annual incidence in Alaska Native children < 2 years old was 624 per 100,000; rates of 84 per 100,000 for meningitis and 290 per 100,000 for bacteremic pneumonia were 8-10 times higher than for other US groups. By age 75, cumulative incidence (7%) and mortality (1%) in Alaska Natives were almost 4 times higher than for nonnatives. Only 17% of Alaska Native adults with predisposing conditions and invasive infections previously received pneumococcal vaccine. For Alaska Natives, a proposed heptavalent conjugate pneumococcal vaccine will include serotypes responsible for 85% of invasive isolates from children < 2 years but only 32% of those from adults. The 23-valent polysaccharide pneumococcal vaccine, which contains > 94% of serotypes identified in Alaska Native toddlers and adults, should be used more widely.

Racial differences in newborn intensive care morbidity in Alaska.

Birthweight-specific neonatal mortality for Alaska Natives is higher than for non-natives for the years 1987-1996. We investigated the reasons for this based on Level III Neonatal Intensive Care Unit information available from 1991-1996. We also investigated whether differences in mortality extended to measures of morbidity. There were less Native patients born at the tertiary care center for babies with birthweight < 1500 grams and 1500-2499 grams (64% for Natives and 87% for non-natives, p = .000). Differences in antenatal referral were only apparent for the population residing within the Anchorage/Mat-Su area. There were also less cesarean deliveries for Native infants that were born outside of the tertiary care center for both birthweight categories (25% for Native vs. 53% for non-native infants < 1500 grams, p = .01; 27% for Native vs. 48% for non-native infants 1500-2499 grams, p = .01). For Alaska Native babies < 1500 grams there was more necrotizing enterocolitis (13% in Native vs. 4.9% in non-native, p = .01), more severe retinopathy of prematurity (12% in Native vs. 4.6% in non-native, p = .01), and more bronchopulmonary dysplasia (49% in Native vs. 34% in non-native, p = .04). For Alaska Native babies 1500-2499 grams that needed ventilatory assistance there was more intraventricular hemorrhage (19% in Native vs. 7.4% in non-native, p = .003), more severe (grade 3-4) intraventricular hemorrhage (9.5% in Native vs. 0.9% in nonnative, p = .001), and more acquired sepsis (7.1% in Native vs. 1.7% in non-native, p = .02). Differences in access to Level III perinatal care and intrapartum care (cesarean delivery rates) are likely factors that contribute to the worse outcomes in the Alaska Native population.

Arterial calcification as a marker for atherosclerosis in three Arctic populations.

Accumulation of calcification in the arterial wall in the course of the atherogenic process is considered to be a manifestation of advanced atherosclerosis. In this study of autopsy specimens from Alaska non-Natives, Alaska Natives, and Greenland Natives, comparisons were made of the prevalence and extent of arterial calcification with that of all raised (advanced) lesions in the thoracic aorta, abdominal aorta, right coronary artery, and left anterior descending coronary artery, to determine the degree to which calcified lesions track the development of advanced lesions. Calcification was determined quantitatively from radiograph images of the fixed specimens; advanced lesion data on these specimens were available from prior studies. Findings show that the prevalence and extent of calcified lesions closely follows the pattern of prevalence and extent of advanced lesions among the groups. We conclude that calcification is a good marker for comparisons of the prevalence and may also provide a good measure of the extent of atherosclerosis in these populations.

Knowledge, intent to use, and use of smokeless tobacco among sixth grade schoolchildren in six selected U.S. sites.

Questionnaires on smokeless tobacco use were completed by 781 sixth grade students in 15 schools at six locations in the United States. The students were both American Indian-Alaska Native and non-American Indian-Alaska Native. The Indian and Alaska Native schoolchildren were experimenting with and regularly using smokeless tobacco at higher rates that non-Indian schoolchildren. At Indian Health Service sites, 28.1 percent of the children reported current use of smokeless tobacco, compared with 3.3 percent of the children elsewhere. For girls reporting smokeless tobacco experimentation, the comparison was 68.9 percent at Indian Health Service sites and 8.7 percent at non-Indian sites; for boys, it was 79.1 percent from the Indian sites and 35.4 percent from the non-Indian sites. For those students who had tried smokeless tobacco, more than half also reported having tried cigarettes. The majority of all sixth grade students surveyed were aware of the health risks of smokeless tobacco use in that it is an increased risk for cancer. Additional research is needed to determine appropriate interventions.

Native Americans' cancer rates in comparison with other peoples of color.

BACKGROUND: The National Cancer Institute developed population-specific programs to better understand cancer as it occurs within underserved populations such as American Indians, Alaska Natives, Native Hawaiians, and American Samoans. METHODS: The data for American Samoans are derived from regional studies and from data collected from the Hawaii Surveillance, Epidemiology, and End Results (SEER) Registry. Native Hawaiian data are from the Hawaii SEER program and are limited to Native Hawaiians who live in that state. Alaska Native data are from the Lanier and Knutson 15-year summary of Alaska Native cancer data. American Indian data are from the New Mexico SEER program, which is generalizable to natives living in Arizona and New Mexico only and is relatively free of racial misclassification errors. RESULTS: An overview of age-adjusted cancer incidence and mortality rates among American Indians, Alaska Natives, Native Hawaiians, African Americans, and whites for 1977-1983 is provided. Five-year relative survival rates from cancer are from 1975-1984. Relative survival rates are provided for American Indians, Native Hawaiians, African Americans, and whites. CONCLUSIONS: Based on the limited data available, divergent cancer patterns appear to be present in these Native American populations. Alaska Natives and Native Hawaiians consistently display elevated rates that are frequently camouflaged when data are collapsed into "other" racial categories.

The Alaska Haemophilus influenzae type b experience: lessons in controlling a vaccine-preventable disease.

OBJECTIVE: Before 1991, Alaska Native children experienced one of the highest rates of invasive Haemophilus influenzae type b disease. H influenzae type b vaccine has led to a near-elimination of invasive H influenzae type b disease in the United States. We describe challenges encountered in controlling H influenzae type b disease in Alaska and update the current status of H influenzae disease and carriage in Alaska as lessons to other populations. PATIENTS AND METHODS: We reviewed data from statewide H influenzae disease surveillance conducted during 1980-2004. Vaccine coverage data were based on audits from tribal facilities and the National Immunization Survey. H influenzae type b colonization data were based on 6 carriage studies. RESULTS: After universal infant vaccination in 1991, H influenzae type b disease among Alaska Native and non-Native children < 5 years of age decreased by 94% and 96%, respectively. After a 1996 change in H influenzae type b vaccine from polyribosylribitol phosphate-outer membrane protein conjugate vaccine to H influenzae type b oligosaccharide-CRM197 vaccine, the incidence of H influenzae type b disease increased in rural Alaska Natives from 19.8 to 91.1 cases per 100000 per year < 5 years of age. During 2001-2004, with use of polyribosylribitol phosphate-outer membrane protein conjugate vaccine, the rate of H influenzae type b disease in Alaska Native and non-Native children aged < 5 years decreased to 5.4 and 0 per 100000 per year, respectively. In postvaccine studies, H influenzae type b carriage has decreased in Alaska Native children < 5 years of age. CONCLUSIONS: H influenzae type b vaccination has resulted in a dramatic decrease in invasive H influenzae type b disease in Alaska; however, despite high rates of H influenzae type b vaccine coverage, H influenzae type b disease rates among rural Alaska Native children < 5 years of age remain higher than the rates among non-Native Alaska and other US children. Equity in disease rates may not be achieved in indigenous populations with the current vaccines unless other environmental and household factors contributing to disease transmission are addressed.

Experience with the prevention of invasive Haemophilus influenzae type b disease by vaccination in Alaska: the impact of persistent oropharyngeal carriage.

OBJECTIVES: To report the epidemiology of invasive Haemophilus influenzae type b (Hib) disease in high-risk Alaska Native infants before and after universal infant Hib vaccination and evaluate an increase in invasive Hib disease in 1996 after changing Hib vaccine type. STUDY DESIGN: Statewide laboratory surveillance for invasive Hib disease has been conducted since 1980. Three cross-sectional Hib carriage studies were conducted in 1997 and 1998. RESULTS: The invasive Hib disease rate in Alaska Natives decreased from 332 cases per 100,000 children <5 years old in 1980-1991 to 17:100,000 in 1992-1995 but increased primarily in rural areas to 57.9:100,000 after a switch in Hib vaccine types. Carriage studies in 5 rural Alaska Native villages showed oropharyngeal Hib carriage as high as 9.3% in children aged 1 to 5 years; in contrast, carriage in urban Alaska Native children was <1%. CONCLUSIONS: Although Hib disease has decreased in Alaska, the rate of Hib disease and carriage in rural Alaska Natives did not decrease to the same extent as in non-Natives and urban Alaska Natives. Use of polyribosylribitol phosphate-outer-membrane protein conjugate vaccine for the first vaccine dose is critical to disease control in this population with continued transmission in infants <6 months of age. The ability to eliminate Hib carriage and disease may be affected by population characteristics, vaccination coverage, and Hib vaccine type used. This may pose a challenge to global elimination of Hib.

Drowning in Alaskan waters.

OBJECTIVE: To enumerate drowning fatalities in Alaska in order to identify risk factors and areas for intervention. METHODS: Information from death certificates, state troopers' reports, and medical examiner reports were abstracted and analyzed. Rates were calculated using 1990 census figures as denominator data. RESULTS: There were 542 drowning fatalities in Alaska for the years 1988 to 1992. The 20-29 age group had the highest frequency and rate of drownings. The incidence rate for the state was 20 drownings per 100,000 population per year, almost 10 times higher than the overall U.S. rate of 2.11 per 100,000 per year. Incidence rates were highest among adolescent males (10-19), young adult males (20-29). Alaska Natives, and rural residents. Alaska Native males, ages 30-39 averaged 159 drownings per 100,000 per year, the highest drowning rates in the state. CONCLUSIONS: Drowning is a major public health concern in Alaska. People who fish commercially and young Native males are groups at high risk for drowning. Intervention efforts should be concentrated on these two populations.

State-specific prevalence of selected health behaviors, by race and ethnicity--Behavioral Risk Factor Surveillance System, 1997.

PROBLEM/CONDITION: In the United States, disparities in risks for chronic disease (e.g., diabetes, cardiovascular disease, and cancer) and injury exist among racial and ethnic groups. This report summarizes findings from the 1997 Behavioral Risk Factor Surveillance System (BRFSS) of the distribution of access to health care, health-status indicators, health-risk behaviors, and use of clinical preventive services across five racial and ethnic groups (i.e., whites, blacks, Hispanics, American Indians or Alaska Natives, and Asians or Pacific Islanders) and by state. REPORTING PERIOD COVERED: 1997. DESCRIPTION OF SYSTEM: The BRFSS is a state-based telephone survey of the civilian, noninstitutionalized, adult (i.e., persons aged > or = 18 years) population. In 1997, all 50 states, the District of Columbia, and Puerto Rico participated in the BRFSS. RESULTS: Variations in risk for chronic disease and injury among racial and ethnic groups exist both within states and across states. For example, in Arizona, 11.0% of whites, 26.2% of Hispanics, and 50.5% of American Indians or Alaska Natives reported having no health insurance. Across states, the median percentage of adults who reported not having this insurance ranged from 10.8% for whites to 24.5% for American Indians or Alaska Natives. Other findings are as follows. Blacks, Hispanics, American Indians or Alaska Natives, and Asians or Pacific Islanders were more likely than whites to report poor access to health care (i.e., no health-care coverage and cost as a barrier to obtaining health care). Blacks, Hispanics, and American Indians or Alaska Natives were more likely than whites and Asians or Pacific Islanders to report fair or poor health status, obesity, diabetes, and no leisure-time physical activity. Blacks were substantially more likely than other racial or ethnic groups to report high blood pressure. Among all groups, American Indians or Alaska Natives were the most likely to report cigarette smoking. Except for Asians or Pacific Islanders, the median percentage of adults who reported not always wearing a safety belt while driving or riding in a car was > or = 30%. The Papanicolaou test was the most commonly reported screening measure: > or = 81% of white, black, and Hispanic women with an intact uterine cervix reported having had one in the past 3 years. Among white, black, and Hispanic women aged > or = 50 years, > or = 63% reported having had a mammogram in the past 2 years. Approximately two thirds of white, black, and Hispanic women aged > or = 50 years reported having had both a mammogram and a clinical breast examination in the past 2 years; this behavior was least common among Hispanics and most common among blacks. Screening for colorectal cancer was low among whites, blacks, and Hispanics aged > or = 50 years: in each racial or ethnic group, < or = 20% reported having used a home-kit blood stool test in the past year, and < or = 30% reported having had a sigmoidoscopy within the last 5 years. INTERPRETATION: Differences in median percentages between racial and ethnic groups, as well as between states within each racial and ethnic group, are likely mediated by various factors. According to published literature, socioeconomic factors (e.g., age distribution, educational attainment, employment status, and poverty), lifestyle behaviors (e.g., lack of physical activity, alcohol intake, and cigarette smoking), aspects of the social environment (e.g., educational and economic opportunities, neighborhood and work conditions, and state and local laws enacted to discourage high-risk behaviors), and factors affecting the health-care system (e.g., access to health care, and cost and availability of screening for diseases and health-risk factors) may be associated with these differences. ACTION TAKEN: States will continue to use the BRFSS to collect information about health-risk behaviors among various racial and ethnic groups. (ABSTRACT TRUNCATED)

Invasive Haemophilus influenzae disease in Alaskan residents aged 10 years and older before and after infant vaccination programs.

CONTEXT: The introduction of Haemophilus influenzae type b (Hib) vaccination of children has led to a decline in incidence of Hib disease in young Alaskan children. However, the impact of vaccination on unimmunized Alaskan adolescents and adults has not been studied. OBJECTIVE: To characterize trends in incidence of and mortality due to invasive H influenzae disease in Alaskan residents aged 10 years and older prior to and after the introduction of a statewide Hib infant vaccination program. DESIGN AND SETTING: Population-based, descriptive correlational study conducted 1980-1996 in Alaska. SUBJECTS: One hundred twenty-nine individuals (31 Alaska Natives and 98 nonnative Alaska residents) aged 10 years and older in whom H influenzae was cultured from a normally sterile site. MAIN OUTCOME MEASURES: Incidence of H influenzae infection before (1980-1990) vs after (1991-1996) vaccination program initiation; serotype, biotype, and beta-lactamase production of isolates. RESULTS: The overall annual incidence of invasive H influenzae in those aged 10 years and older declined 33%, from 2.1 per 100,000 persons per year to 1.4 per 100,000 persons per year (P=. 03) after initiation of statewide infant Hib vaccination programs in 1991. This reduction appeared to be the result of a decrease in serotype b disease (82%; P<.001). Infection with other H influenzae serotypes and nontypeable strains increased from 0.5 per 100,000 persons per year to 1.1 per 100,000 persons per year (P=.01). Incidence declined from 4.2 per 100,000 persons per year to 1.2 per 100,000 persons per year in Alaska Natives (P=.005) and from 1.7 per 100,000 persons per year to 1.4 per 100,000 persons per year in nonnative Alaska residents (P=.37). Pneumonia (43%), sepsis (26%), and meningitis (16%) were the most common clinical presentations. Alcohol/drug abuse was comorbid in 15% of patients, while 13% of patients were pregnant women. beta-Lactamase production occurred in 35% of isolates and was stable throughout the surveillance. The overall case-fatality rate was 15%. CONCLUSION: The overall statewide incidence of invasive H influenzae infections in unimmunized persons aged 10 years and older decreased after the initiation of an infant Hib vaccine program, perhaps by decreasing Hib carriage in child reservoirs. An increase in non-serotype b strains was observed. This trend justifies the need for continued surveillance of invasive disease caused by H influenzae. JAMA. 2000.

Early radiographic and clinical features associated with bronchiectasis in children.

Bronchiectasis among children living in developing regions is associated with respiratory infections during early childhood, but specific risk factors that precede childhood bronchiectasis are not fully characterized. We hypothesized that severe respiratory syncytial viral (RSV) infection in infancy would increase the risk of bronchiectasis among Alaska Native children in rural Alaska. This was a follow-up cohort study of a 1993-1996 case-control study of RSV-hospitalized case patients and their controls. For each 5-8-year-old former case-patient and control subject, we reviewed medical records, interviewed parents, performed physical examinations and spirometry, collected sera, and analyzed all historical chest radiographs. Ten (11%) RSV cases and 10 (9%) controls had radiographic evidence of bronchiectasis. The mean age at radiographic diagnosis of bronchiectasis was 3.3 years (range, 1.2-6.1 years). Children were more likely to develop bronchiectasis if their chest radiographs, when they were < 2 years of age, showed lung parenchymal densities (RR = 3.9, P < 0.013), persistent parenchymal densities > 6 months' duration (RR = 3.0, P = 0.02), or infiltrates on multiple episodes (test for trend, P = 0.003). Radiographic features of hyperinflation and atelectasis among children < 2 years old were not associated with eventual bronchiectasis. A single severe infection with RSV alone did not predispose Alaska Native infants to bronchiectasis. Childhood bronchiectasis was associated with lung and hence airway injury, manifested on radiographs by parenchymal densities or "pneumonia" rather than by hyperinflation or atelectasis.

Differences in cancer incidence among Indians in Alaska and New Mexico and U.S. Whites, 1993-2002.

Cancer incidence for American Indians and Alaska Natives is typically reported as a single rate for all U.S. indigenous populations combined. Previously reported combined rates suggest that American Indians and Alaska Natives have lower cancer incidence rates compared with the U.S. population. Alaska Native people comprise three major ethnic groups: Eskimo, Indian, and Aleut people. We examined cancer incidence from only Alaska Indians and compared incidence rates with an American Indian population living in New Mexico. These data indicate striking differences in cancer patterns between two American Indian populations. Cancer data for the years 1993 to 2002 for American Indians of New Mexico and U.S. Whites are from the National Cancer Institute Surveillance, Epidemiology, and End Results Program Public-use data set. Data for Alaska Indians are from the Alaska Native Tumor Registry, which is also a Surveillance Epidemiology and End Results Program participant. Overall, cancer incidence rates for all sites combined in New Mexico Indian men and women were lower than U.S. White rates, whereas Alaska Indian men and women exceeded U.S. rates. In comparing Alaska and New Mexico Indians, we observed a 2.5-fold higher incidence of cancer among Alaska Indians. The largest differences between the two Indian populations were noted primarily in cancers associated with tobacco use, including cancers of the oral cavity/pharynx, esophagus (only in men), colon and rectum, pancreas, larynx (men), lung, prostate, and urinary bladder (men). Lung cancer rates in Alaska Indian men and women were 7 and 10 times those of New Mexico Indian men and women.

Prevalence of diabetes mellitus in Alaskan Eskimos, Indians, and Aleuts.

The prevalence of diabetes mellitus in Alaska Natives has been thought to be low, but no survey of this condition in all natives has been conducted. Medical records from 1979 to 1985 were reviewed to determine the prevalence of diagnosed diabetes mellitus in Alaska Natives. Computerized outpatient and inpatient medical record data and clinician reports were used to identify cases. As of December 1985, 610 living Alaska Natives fulfilled diagnostic criteria for diabetes. Type II diabetes mellitus was found in 564 subjects, type I diabetes was found in 15 subjects, and unspecified type of diabetes was found in 31 subjects. The overall age-adjusted prevalence of diabetes mellitus, 15.7/1000, was lower than the overall United States rate of 24.7/1000. However, age-adjusted prevalence varied considerably by ethnic group; the prevalence was 27.2/1000 among Aleuts, 22.0/1000 among Alaskan Indians, and 8.8/1000 among Alaskan Eskimos. Rates within the Eskimo subgroups varied by a factor of four. Compared with previous reports, the prevalence of diabetes mellitus in Alaskan Eskimos appears to have increased. Diabetes mellitus is no longer a rare condition among Alaska Natives.
