Sociocultural stress and the American native in Alaska: an analysis of changing patterns of psychiatric illness and alcohol abuse among Alaska natives.

This paper presents selected morbidity and mortality statistics to outline developing trends and the current status of psychiatric illness and alcohol abuse among the Aleut, Athabascan, Yupik, Inupiat, Tlingit, Haida and Tsimpshian people of Alaska. Analysis of the records of the Indian Health Service, the Community Mental Health Centers and the Alaska Psychiatric Institute, the providers of care for Alaska Natives, shows that the number of individuals treated as inpatients and outpatients for psychiatric illness and alcohol abuse has been rising steadily. Accidental injury and suicidal behavior are common. The treated prevalence rates for these diagnoses exceed recorded rates for other American Native and non-Native groups. For each category of violent death, suicide, homicide, accidents and alcohol, rates for Alaska Natives are higher than rates for Alaska non-Natives, American Indians and the U.S. (all races) and are rising. The data suggest a public health problem in which the primary elements are behavioral disturbance and violent death.

Severity and frequency of sequelae of bacterial meningitis in Alaska Native infants. Correlation with a scoring system for severity of sequelae.

OBJECTIVES: To (1) determine the frequency and severity of sequelae of Haemophilus influenzae type b and Streptococcus pneumoniae meningitis in Alaska Native children, (2) compare morbidity and mortality of H influenzae b and S pneumoniae meningitis, and (3) evaluate the applicability of the Herson-Todd prognostic score (HTPS) to both H influenzae b and S pneumoniae meningitis in this population. DESIGN: A retrospective study of all cases of H influenzae b and S pneumoniae meningitis in Alaska Native children younger than age 5 years. Data on meningitis sequelae, obtained from medical charts and records of the Infant Learning Program, were collected, and incidence of sequelae tabulated. Data obtained on admission to the hospital were used to calculate HTPS. SETTING: Indian Health Service facility for the Yukon-Kuskokwin Delta region of southwest Alaska. STUDY SUBJECTS: 51 of 63 Alaska Native children with H influenzae b meningitis and 13 of the same 63 Alaska Native children with S pneumoniae meningitis occurring between 1980 and 1988. One child was infected with both organisms, producing a total of 64 cases for study. SELECTION PROCEDURES: Cases were identified by surveillance for these diseases between January 1, 1980, and December 31, 1988, maintained by the Arctic Investigations Program, Centers for Disease Control. MEASUREMENTS AND RESULTS: Sequelae of bacterial meningitis caused by H influenzae b were equal to or exceeded rates of sequelae described in other children in the United States. After H influenzae b meningitis, motor abnormalities (29%) and hydrocephalus (7%) occurred two to four times more often in Alaska Native children than in children in other parts of the United States. Differences in severity of H influenzae b sequelae could not be accounted for by microbiologic markers of the H influenzae b strain, including ampicillin sensitivity, biotype, outer membrane protein type, or electropherotype. Numbers of cases of S pneumoniae meningitis were too small for statistically valid comparison, but sequelae of S pneumoniae meningitis occurred in roughly equal proportion as sequelae of H influenzae b meningitis. The HTPS was applied to Alaska Native children with H influenzae b meningitis and was found to be very accurate in predicting children with major sequelae. Analysis of the prognostic factors used in deriving the HTPS revealed a unique set of predictors for sequelae in Alaska Native children: seizures at admission, glucose levels in cerebrospinal fluid of less than 1.1 mmol/L; and male gender, with a significant predictive interaction between male gender and age less than 6 months at admission. CONCLUSIONS: Alaska Native children suffer greater neurologic morbidity as a result of H influenzae b meningitis than do their non-Native counterparts. The HTPS was a good predictor of major sequelae in Alaska Native children with H influenzae b or S pneumoniae meningitis and could be useful in determining which patients need referral to a tertiary care center.

The diet of Alaska Native adults: 1987-1988.

Although in the past, rates of heart disease, cancer, and diabetes were lower in Alaska Natives than in US whites, these diseases are now increasing. The rate of iron-deficiency anemia for Alaska Natives continues to be higher than that in the general population. To understand the role of diet in these chronic diseases, seasonal dietary intakes of 351 Alaska Native adults from 11 communities were assessed during 1987-1988. Alaska Natives consumed more energy (19%), protein (39%), fat (21%), carbohydrate (13%), iron (25%), vitamin A (53%), and vitamin C (31%), but less calcium (19%) than did the general US adult population [National Health and Nutrition Examination Survey II (NHANES II)]; Alaska Natives consumed six times more fish but less fruits and vegetables. Results suggest that energy and protein intakes decreased in the last 30 y but the proportion of energy from fat (37%) remained unchanged. High fish consumption and large seasonal dietary variations persisted, which may protect against chronic diseases. However, excess energy and fat and low calcium, fruit, and vegetable intakes may be contributing to recent increases in chronic diseases. Dietary guidelines are proposed.

The contribution of reinfection to gonorrhea incidence in Alaska, 1983 to 1987.

Gonorrhea case reports to the Alaska Department of Health and Social Services were used to study the contribution of reinfection to rates of gonorrhea infection in Alaska. The case reports of 13,910 infections among 11,132 persons who had laboratory-proven gonorrhea between 1983 and 1987 were examined. Among 1,886 persons who had multiple infections, the average number of infections per person was 2.5 (range = 2-11). These persons accounted for 33.5% of all infections and 16.9% of all patients with gonorrhea from 1983 to 1987. Compared to persons with one infection, those having multiple infections were more likely to be Alaska Natives (relative risk = 1.8, 95% confidence interval = 1.6-1.9) and less than 21 years of age (relative risk = 1.3, 95% confidence interval = 1.2-1.4). There was no difference in risk between men and women. Two thirds of the reinfections occurred within 12 months of the initial infection. If gonorrhea incidence were calculated based on the number of people infected rather than as a "case rate," the mean annual rate (per 100,000) from 1983 to 1987 decreased from 1,644 to 1,228 (a 25.3% decrease) for Alaska Natives and from 316 to 267 (a 15.5% decrease) for non-Natives. Reporting gonorrhea incidence rates by number of persons infected rather than by total number of cases more accurately measures gonorrhea morbidity in a population and will allow prevention efforts to be directed to those persons who contribute the most to perpetuating the disease.

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.

Surveillance of traumatic occupational fatalities in Alaska--implications for prevention.

Data on occupational injury fatalities in Alaska for the period 1980-85 were complied from workers' compensation claims and death certificates. These data yielded 422 unique cases for the 6-year period, for an average annual fatality rate of 36.3 per 100,000 workers. This rate is 5 times higher than the Bureau of Labor Statistics estimate of 7.6 per 100,000 for the United States during the same period. The four industries with the highest fatality rates were the same for Alaska as for the nation (agriculture-forestry-fishing, construction, mining, and transportation-communication-public utilities). The leading causes of occupational fatalities in Alaska, however, were considerably different than for the United States as a whole. Nationally, motor vehicles and industrial equipment accidents are the leading causes of death. In Alaska, the leading causes of occupational injury mortality are aircraft crashes and drowning. These findings highlight the benefit of local surveillance in planning prevention strategies.

American Indian--Alaska Native youth health.

OBJECTIVE: To assess risk behaviors, health problems, worries and concerns, and resiliency-promoting factors among American Indian-Alaska Native adolescents. DESIGN: Survey. SETTING: Nonurban schools from eight Indian Health Service areas. PARTICIPANTS: A total of 13,454 seventh- through 12th-grade American Indian-Alaska Native youths. MAIN OUTCOME MEASURES: revised version of the Adolescent Health Survey, a comprehensive, anonymous, self-report questionnaire with 162 items addressing 10 dimensions of health. RESULTS: Poor physical health was reported by 2% of the study sample and was significantly correlated with social risk factors of physical and/or sexual abuse, suicide attempts, substance abuse, poor school performance, and nutritional inadequacies. Injury risk behaviors included never wearing seatbelts (44%), drinking and driving (37.9% of driving 10th through 12th graders), and riding with a driver who had been drinking (21.8%). Physical and sexual abuse prevalence was 10% and 13%, respectively, with 23.9% of females reporting physical abuse and 21.6% of females reporting sexual abuse by the 12th grade. Almost 6% of the entire sample endorsed signs of severe emotional distress. Eleven percent of the teens surveyed knew someone who had killed himself or herself, and 17% had attempted suicide themselves. Sixty-five percent of males and 56.8% of females reported having had intercourse by the 12th grade. Weekly or more frequent alcohol use rose from 8.2% of seventh graders to 14.1% by the 12th grade; for males, the survey noted an increase in regular alcohol use of 3% to 5% a year to 27.3% by the 12th grade. For each variable measured, rates are much higher for American Indian adolescents than those for rural white Minnesota youth, except for age at first intercourse and alcohol use. CONCLUSIONS: American Indian-Alaska Native adolescents reported high rates of health-compromising behaviors and risk factors related to unintentional injury, substance use, poor self-assessed health status, emotional distress, and suicide. Interventions must be culturally sensitive, acknowledge the heterogeneity of Indian populations, be grounded in cultural traditions that promote health, and be developed with full participation of the involved communities.

An oral health survey of Head Start children in Alaska: oral health status, treatment needs, and cost of treatment.

The purpose of this study was to obtain information on the oral health status, treatment needs, and cost of treatment for Head Start children in Alaska. Twenty communities, representing five regions within the state, were selected for participation. The study consisted of three distinct parts: a caries status exam, a sociodemographic questionnaire, and a treatment needs examination. A total of 544 children between three and five years old were examined. The mean dmft and dmfs scores were 3.91 and 8.73, respectively. When stratified by race, the Alaska Native children had significantly higher mean dmft and dmfs scores. When stratified by community of residence, those children residing in the rural communities had higher rates of dental caries than the urban children. Forty-five percent of the total sample was in need of dental restorative treatment, excluding examinations, radiographs, and preventive services. The proportion of rural children needing care was much higher than the urban children (59% vs 27%). On average, each urban child needed treatment on 0.7 teeth, while each rural child needed treatment on 2.8 teeth. When all treatment factors including sedation and transportation costs are considered, the potential cost of treatment for the 1,475 children enrolled in the Alaska Head Start programs was $601,624.

The Alaska Trauma Registry.

Recognizing that injury is the leading cause of death and disability for virtually all age groups in Alaska, a trauma task force was developed in the Anchorage area in the early 1980s. This task force established the trauma registry pilot project in the state of Alaska. The Emergency medical Services Section, Department of Health and Social Services provided the funding to the Southern Region Emergency Medical Services Council, Inc. and the Alaska Chapter of the American College of Surgeons Committee on Trauma to develop this pilot project. The funding originated from a federal grant from the National Highway Traffic Safety Administration. Seven hospital participated in the pilot project which lasted approximately two and one half years. There were 5,087 entries into the registry with information on 4,860 patients. The rationale, methodology, and development of the registry, as well as some of the data accumulated is presented. The potential usefulness of the registry as a quality improvement tool and as an extensive data base for injury prevention and trauma care research also is discussed.

Misclassification of infant deaths--Alaska, 1990-1991.

In June 1991, the Alaska Section of Vital Statistics reported that nine deaths of Alaskan Native infants occurred in seven villages in southwestern Alaska from January 1990 through June 1991. In comparison, seven Alaskan Native infant deaths occurred in these villages during 1986-1989. Two of the deaths during 1990-1991 had been attributed to acute viral myocarditis (International Classification of Diseases, Ninth Revision [ICD-9], code 422.9) and three to viral or unspecified pneumonitis (ICD-9 codes 480.9 and 486), while from 1985 through 1989, one infant death in these villages had been attributed to either of these causes. An examination of the clinical histories of these nine infants by the Alaska Division of Public Health (ADPH) suggested some of the diagnoses might be inaccurate. This report summarizes an investigation by the ADPH to assess the accuracy of the immediate cause of death recorded on the death certificates for the nine infants.

Clustering of hepatocellular carcinoma in Alaska Native families.

Alaska Natives have a high incidence of hepatocellular carcinoma (HCC), with regional, ethnic, village, and familial clustering. During 1969-1988, 15 of the 45 incident cases of HCC in Alaska Natives occurred in 5 families. This report presents epidemiologic, virologic, and immunogenetic data on these 5 families. The results of hepatitis B virus (HBV) serologic testing indicates that HBV infection was an important factor in 4 of the 5 families. Human lymphocyte antigen (HLA) testing was performed in 3 families. The HLA results are reviewed in relationship to the familial clustering of HCC.

Cancer incidence in Alaska natives.

A survey of cancer incidence among Alaska Natives for the 5-year period 1969-73 revealed fewer cancer cases overall than expected in relation to US rates, but significantly increased risk for certain cancer sites: the nasopharynx in both sexes (with excesses over 15-fold), the liver in males, and the salivary glands, gallbladder, kidney and thyroid in females. Compared with earlier reports, the observations suggest marked changes in cancer incidence among Alaska Natives over the past two decades, with declines in esophageal and invasive cervical cancers, and increases in cancers of the lung, colon and rectum.

Discovery and characterization of multifunctional bioactive peptides from Alaska Pollock (Gadus chalcogrammus) milt: hybrid in silico, in vitro, and proteomic approaches.

The growing demand for multifunctional bioactive peptides has sparked interest in underutilized marine by-products as sustainable bioresources. This study explored Alaska Pollock (Gadus chalcogrammus) milt protein as a novel source of peptides with anti-inflammatory, anti-hypertensive, and anti-diabetic effects. Protein composition was analyzed via LC-MS, followed by in silico digestion and bioactivity prediction. Molecular docking identified peptides targeting DPP-IV, α-glucosidase, ACE, GLP-1 receptor, COX-2, MuRF1, and the 20S proteasome. Among the candidates, a promising peptide (CLPPH) was synthesized and validated in vitro, demonstrating inhibitory effects on nitric oxide production, DPP-IV, ACE, and α-glucosidase. These results highlight CLPPH's potential as a multifunctional bioactive peptide and support the valorization of Alaska Pollock milt as a sustainable source for functional foods and nutraceutical applications.

Bacterial meningitis in southwestern Alaska.

Between July 1, 1971, and June 30, 1974, thirty-nine cases of bacterial meningitis were diagnosed at the Alaska Native Health Service Hospital at Bethel, Alaska. Thirty-two (82%) occurred in infants less than one year of age. Haemophilus influenzae (H. influenzae) was the predominant causative agent, and was isolated from 23 (72%) of the 32 patients under one year of age. The annual incidence of H. influenzae meningitis in the Bethel area was 63/100,000, and the annual incidence of H. influenzae meningitis in children less than five years of age was 474/100,000 cases.

Prevalence of seasonal affective disorder in Alaska.

OBJECTIVE: The goals of this study are to provide estimates of the prevalence of seasonal affective disorder in Alaska, to examine sociodemographic correlates, and to evaluate the relation between seasonal affective disorder and general depression. METHOD: A random sample of 283 residents of Fairbanks who had lived in Alaska for 3 years or more were interviewed with the Seasonal Pattern Assessment Questionnaire and the Center for Epidemiologic Studies Depression Scale (CES-D Scale). RESULTS: Twenty-six (9.2%) of the subjects met diagnostic criteria for seasonal affective disorder, one of the highest figures yet reported. These cyclic winter affective disorders occurred more often in women than men (ratio = 3:2) and were less prevalent among residents who were older than 40 years of age. Assessment of depression with the CES-D Scale supported the diagnostic classification of respondents and the differentiation of seasonal affective disorder from other depression. CONCLUSIONS: This study supports the conclusions that seasonal affective disorder is prevalent in northern populations and that sex and age may represent the major risk factors that differentiate it from the general experience of depression in northern communities.
