Combating the diabetes epidemic.

What would happen if one could develop diabetes as quickly as catching the common cold? Well of course this is not the case, but diabetes is becoming more and more common in the United States. From the period 1980 through 2002, the number of Americans diagnosed with diabetes mellitus more than doubled (from 5.8 million people to 13 million people). New evidence reveals that one in three Americans born in 2000 will develop diabetes sometime during their lifetime. Diabetes has the greatest impact on older adults, women, and particular racial and ethnic groups. One in five adults over the age of 65 has diabetes. African Americans, Hispanics, Native American Indians and Alaska Native adults are two to three times more likely than Caucasian adults to have diabetes. In addition to these statistics, an estimated 41 million United States adults aged 40-74 have prediabetes. Prediabetes is defined as blood glucose elevated more than normal, but not increased enough to be classified as that of diabetes mellitus. Fasting blood glucose levels greater than 100 mg/dl but less than 126 mg/dl is characteristic of prediabetes. These people are at great risk for developing diabetes.

Assessment of the National Library of Medicine's health disparities plan: a focus on Native American outreach.

OBJECTIVES: Overcoming health disparities between majority and minority populations is a significant national challenge. This paper assesses outreach to Native Americans (American Indians, Alaska Natives, and Native Hawaiians) by the National Library of Medicine (NLM). A companion paper details NLM's portfolio of Native American outreach projects. METHOD: NLM's Native American outreach is assessed in light of the presentations at a community-based health information outreach symposium and the goals set by NLM's plan to reduce health disparities. RESULTS: NLM's current portfolio of Native American outreach projects appears most advanced in meeting the goal set in area 1 of the health disparities plan, "Promote use of health information by health professionals and the public." NLM's portfolio also shows significant strength and good progress regarding area 2 of the plan, "Expand partnerships among various types of libraries and community-based organizations." The portfolio is weaker in area 3, "Conduct and support informatics research." More knowledge-building efforts would benefit NLM, the National Network of Libraries of Medicine, and Native American and community-based organizations. IMPLICATIONS: The current Native American outreach portfolio should be continued, but new approaches are needed for evaluating Native American outreach and for forging collaborations with Native American groups, approaches grounded in consultation and mutual understanding of needs and perspectives.

The National Library of Medicine's Native American outreach portfolio: a descriptive overview.

OBJECTIVES: This paper provides the most complete accounting of the National Library of Medicine's (NLM's) Native outreach since 1995, when there were only a few scattered projects. METHOD: The descriptive overview is based on a review of project reports, inventories, and databases and input from the NLM Specialized Information Services Division, National Network Office of the Library Operations Division, National Network of Libraries of Medicine, and Office of Health Information Programs Development of the Office of the NLM Director. The overview focuses on NLM-supported or sponsored outreach initiatives involving Native peoples: American Indians, Alaska Natives, and Native Hawaiians. RESULTS: The review of NLM's relevant activities resulted in a portfolio of projects that clustered naturally into the following areas: major multisite projects: Tribal Connections and related, Native American Information Internship Project: Sacred Root, tribal college outreach and tribal librarianship projects, collaboration with inter-tribal and national organizations, participation in Native American Powwows, Native American Listening Circle Project, Native American Health Information, and other Native American outreach projects. IMPLICATIONS: NLM's Native American Outreach reached programmatic status as of late 2004. The companion paper identifies several areas of possible new or enhanced Native outreach activities. Both papers highlight the importance of solid reporting and evaluation to optimize project results and programmatic balance and priorities.

American Academy of Pediatrics. Committee on Infectious Diseases. Policy statement: recommendations for the prevention of pneumococcal infections, including the use of pneumococcal conjugate vaccine (Prevnar), pneumococcal polysaccharide vaccine, and antibiotic prophylaxis.

Heptavalent pneumococcal conjugate vaccine (PCV7) is recommended for universal use in children 23 months and younger, to be given concurrently with other recommended childhood vaccines at 2, 4, 6, and 12 to 15 months of age. For children 7 to 23 months old who have not received previous doses of PCV7, administration of a reduced number of doses is recommended. Two doses of PCV7 are recommended for children 24 to 59 months old at high risk of invasive pneumococcal infection-including children with functional, anatomic, or congenital asplenia; infection with human immunodeficiency virus; and other predisposing conditions-who have not been immunized previously with PCV7. Recommendations have been made for use of 23-valent pneumococcal polysaccharide (23PS) vaccine in high-risk children to expand serotype coverage. High-risk children should be given vaccines at the earliest possible opportunity. Use of antibiotic prophylaxis in children younger than 5 years with functional or anatomic asplenia, including children with sickle cell disease, continues to be recommended. Children who have not experienced invasive pneumococcal infection and have received recommended pneumococcal immunizations may discontinue prophylaxis after 5 years of age. The safety and efficacy of PCV7 and 23PS in children 24 months or older at moderate or lower risk of invasive pneumococcal infection remain under investigation. Current US Food and Drug Administration indications are for administration of PCV7 only to children younger than 24 months. Data are insufficient to recommend routine administration of PCV7 for children at moderate risk of pneumococcal invasive infection, including all children 24 to 35 months old, children 36 to 59 months old who attend out-of-home care, and children 36 to 59 months old who are of Native American (American Indian and Alaska Native) or African American descent. However, all children 24 to 59 months old, regardless of whether they are at low or moderate risk, may benefit from the administration of pneumococcal immunizations. Therefore, a single dose of PCV7 or 23PS vaccine may be given to children 24 months or older. The 23PS is an acceptable alternative to PCV7, although an enhanced immune response and probable reduction of nasopharyngeal carriage favor the use of PCV7 whenever possible.

American Academy of Pediatrics. Committee on Infectious Diseases. Technical report: prevention of pneumococcal infections, including the use of pneumococcal conjugate and polysaccharide vaccines and antibiotic prophylaxis.

Pneumococcal infections are the most common invasive bacterial infections in children in the United States. The incidence of invasive pneumococcal infections peaks in children younger than 2 years, reaching rates of 228/100,000 in children 6 to 12 months old. Children with functional or anatomic asplenia (including sickle cell disease [SCD]) and children with human immunodeficiency virus infection have pneumococcal infection rates 20- to 100-fold higher than those of healthy children during the first 5 years of life. Others at high risk of pneumococcal infections include children with congenital immunodeficiency; chronic cardiopulmonary disease; children receiving immunosuppressive chemotherapy; children with immunosuppressive neoplastic diseases; children with chronic renal insufficiency, including nephrotic syndrome; children with diabetes; and children with cerebrospinal fluid leaks. Children of Native American (American Indian and Alaska Native) or African American descent also have higher rates of invasive pneumococcal disease. Outbreaks of pneumococcal infection have occurred with increased frequency in children attending out-of-home care. Among these children, nasopharyngeal colonization rates of 60% have been observed, along with pneumococci resistant to multiple antibiotics. The administration of antibiotics to children involved in outbreaks of pneumococcal disease has had an inconsistent effect on nasopharyngeal carriage. In contrast, continuous penicillin prophylaxis in children younger than 5 years with SCD has been successful in reducing rates of pneumococcal disease by 84%. Pneumococcal polysaccharide vaccines have been recommended since 1985 for children older than 2 years who are at high risk of invasive disease, but these vaccines were not recommended for younger children and infants because of poor antibody response before 2 years of age. In contrast, pneumococcal conjugate vaccines (Prevnar) induce proposed protective antibody responses (>.15 microg/mL) in >90% of infants after 3 doses given at 2, 4, and 6 months of age. After priming doses, significant booster responses (ie, immunologic memory) are apparent when additional doses are given at 12 to 15 months of age. In efficacy trials, infant immunization with Prevnar decreased invasive infections by >93% and consolidative pneumonia by 73%, and it was associated with a 7% decrease in otitis media and a 20% decrease in tympanostomy tube placement. Adverse events after the administration of Prevnar have been limited to areas of local swelling or erythema of 1 to 2 cm and some increase in the incidence of postimmunization fever when it is given with other childhood vaccines. Based on data in phase 3 efficacy and safety trials, the US Food and Drug Administration has provided an indication for the use of Prevnar in children younger than 24 months.

Incidence of hip fracture in Alaska Inuit people: 1979-89 and 1996-99.

Review of records of the Alaska Native Medical Center in Anchorage, Alaska show that the incidence of hip fracture in Inuit women over 64 years of age was higher than the incidence in white US women in 1979-89 and had increased farther by 1996-99. The hip fracture incidence of Inuit men was higher than US men in 1996-99.

Research and American Indian/Alaska Native health: a nursing perspective.

American Indians and Alaska Natives (AI/AN) have increasing rates of chronic diseases and other health problems that have known preventable risk factors. Yet AI/AN health professionals and researchers are few in number. Because of past negative experiences with outside researchers, AI/AN communities do not always view health research favorably. This article reviews health and related research issues as well as to recommend improving interaction among community and all researchers.

Frequency distributions of breast cancer characteristics classified by estrogen receptor and progesterone receptor status for eight racial/ethnic groups.

BACKGROUND: The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) cancer registries have been collecting data regarding estrogen receptor (ER) and progesterone receptor (PR) status in breast cancer since 1990. The current study reports on some of these data for eight racial/ethnic groups. METHODS: Stratified by ER and PR status, the frequency distributions of 112,588 breast cancer cases diagnosed between 1992--1997 in 11 SEER cancer registries were examined by age at diagnosis, stage at diagnosis, histologic grade, and tumor type for white, black, Hispanic, Japanese, Chinese, Filipino, Native Hawaiian, and American Indian and Alaska Native (AI/AN) females. RESULTS: For each racial/ethnic group, the percentage of ER positive (+)/PR+ was > ER-PR- > ER+PR- > ER-PR+ tumors. For the two major ER/PR groups, the ER+PR+ tumors were different from the ER-PR- tumors in several ways. For white females, there were differences in the age distributions, stage at diagnosis, and histologic grade. For black females, the differences involved the age distributions and tumor grades. For Hispanic and Japanese females, there were differences with regard to the age distributions and tumor grades. For Filipino, Chinese, and AI/AN females, the tumor stages and grades differed. For Native Hawaiians, the histologic tumor grades were different. CONCLUSIONS: For each racial/ethnic group, the ER/PR status appeared to divide breast cancer patients into two or more subgroups with unique tumor characteristics. In general, ER status appeared to have the greatest impact on delineating these subgroups, whereas in some cases, PR status was able to modify the subgroups further. It is hoped that reporting these tumor characteristics by ER/PR status for each racial/ethnic group will spur more investigation into the significance of ER/PR status in each racial/ethnic group.

Physical activity and Native Americans: a review.

The physical activity behaviors of Native-American populations in the United States and Canada have received little attention in the health literature. The purpose of this review was to unite the literature regarding the physical activity behaviors of Native Americans. A majority of the literature was obtained using online databases. Reference lists were also reviewed to gain further access to the literature. Key-word searches included various combinations of Aboriginal, Native Indian, American Indian, Native American, First Nation, Métis, or Alaska Native with physical activity, exercise, and health behavior. Articles included were those published in English-language, peer-reviewed journals from 1990 until November 2005 that focused on participants aged 18 years and older. This review is organized according to ecologic models of health behavior, which take into account several correlates to explain human behavior, including demographic, personal health, environmental, and psychosocial. Correlates were included if they appeared at least three times in the literature. As a result of these inclusion criteria, the number of reviewed articles includes 28 quantitative, 4 qualitative, and 3 intervention studies. Results indicate that age, gender, and social support are important factors associated with physical activity. The remaining correlates show inconsistent or indeterminate results due in part to the paucity of research. It is suggested that an increase in the number of studies, especially those using longitudinal designs, is needed. Further, the application of psychosocial models to understand physical activity motivations as well as culturally appropriate and validated measurement tools are largely absent in the Native-American physical activity literature.

Out of harmony: health problems and young Native American men.

Studies of the current health status of healthy young Native American men (American Indians and Alaska Natives) are rare compared with the attention researchers have given the many problems that plague the lives of these young men. Native American men are frequently not included in other studies focusing on men, and information on college-aged, healthy young Native American men is generally not readily available. Despite those drawbacks, this article brings together what is written or known about the health status of young Native American men. The emphasis, based on available information, is placed on some of the major health problems confronting this population.

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.

3000 by 2000 and beyond: next steps for promoting diversity in the health professions.

In 1991, the Association of American Medical Colleges (AAMC) launched a national campaign to enroll 3,000 underrepresented minority students in medical school by the year 2000. (The AAMC defined underrepresented minorities as blacks, Mexican Americans, mainland Puerto Ricans, and Native Americans, which includes American Indians, Alaska Natives, and Native Hawaiians.*) The initiative, named Project 3000 by 2000, focused on education-pipeline interventions. Although the project did not meet its numeric goal, in large part because of court decisions in several regions of the country that hampered affirmative action programs, Project 3000 by 2000 did have a number of important successes. At a time when there is a need to develop new and creative ways to promote diversity in health professions education, there are a number of lessons to be learned from this project. Large-scale national campaigns serve an extremely useful purpose in promoting diversity in the health professions. And for these campaigns to be successful, it is important that the health professions work together to coordinate their activities and share their resources to ensure that health professions close the diversity gap in the twenty-first century.

Decline of Haemophilus influenzae type b disease in a region of high risk: impact of passive and active immunization.

Haemophilus influenzae type b (Hib) is a major cause of serious childhood bacterial infections. Before 1989 Alaska Native infants in the Yukon Kuskokwim Delta (YKD) had the highest recorded Hib disease rate, 2960:100,000 in children less than 1 year of age with 6 to 35 (mean, 13) cases/year between 1980 and 1988. In July, 1989, Alaska Area Native Health Service initiated a passive immunization project in the YKD using bacterial polysaccharide immunoglobulin (BPIG) administered at 3-month intervals to prevent Hib infections in infants less than 13 months of age. On January 1, 1991, after licensure of Hib conjugate vaccines for infants, the program was modified to a passive-active strategy using BPIG at birth and PedvaxHIB at 2, 4 and 12 months of age. Between July 1, 1989, and December 31, 1990, 80% of YKD children less than 1 year of age received at least 1 dose of BPIG. During this period there were 7 Hib cases in this age group, but only 1 of the cases had received any BPIG. Between January 1, 1991, and December 31, 1992, 4 Hib cases occurred in 2 YKD children. During the combined period, July 1, 1989, to December 31, 1992, the incidence of Hib disease for infants less than 1 year of age was 302:100,000. A dramatic decrease in Hib disease was observed in this high incidence region concurrent with implementation of passive and passive-active immunization strategies.

Cancer-related health disparities in women.

OBJECTIVES: This article synthesizes information about cancer in 9 populations of minority women: Mexican American, Puerto Rican, Cuban American, African American, Asian American, Native Hawaiian, American Samoan, American Indian, and Alaska Native. METHODS: Cancer registry data, social indicators, government sources, and published articles were searched for information on the background and cancer experience of these 9 racial/ethnic groups. RESULTS: Approximately 35 million women in these racial/ethnic groups live in the United States, and their numbers are increasing rapidly. Since 1992, incidence rates for major cancer sites have slowed or decreased among these groups, but declines in mortality have not occurred or have been smaller than for Whites. Gaps in early detection have narrowed, but minority women still lag behind Whites. Smoking and obesity remain common in these populations. CONCLUSIONS: More culturally appropriate interventions and research are needed, and these efforts must involve the community and raise the quality of health services.

Cardiac mortality in Alaska's indigenous and non-Native residents.

Cardiac disease mortality in Alaska, from both ischaemic and rheumatic heart disease, is of interest given the high consumption of fish and high streptococcal disease rates in the indigenous population. Uniformly coded underlying cause-of-death data for the period 1979-1988, compared with that from 1955-1965, indicated that deaths from all cardiac diseases combined, have been increasing in Alaska Natives over the past 30 years. Recent mortality from all cardiac, ischaemic, and rheumatic heart diseases in Alaska Natives were 80%, 61%, and 202% of those corresponding levels in Alaskan whites, whose cardiac mortality closely profiles US whites. Alaska Native men aged 30-45 years had higher overall mortality rates for cardiac diseases than did whites because of higher mortality rates of rheumatic heart disease and cardiomyopathy. Elderly Alaska Native men had lower rates than whites, reflecting less ischaemic heart disease mortality. The lowest levels of ischaemic heart disease mortality, less than one-third that of US whites, occurred in Alaskan Eskimos who lived in an area with documented patterns of high salmon consumption by individuals with high blood concentrations of omega-3 fatty acids. Elevated mortality from non-ischaemic heart disease and previously documented genetic markers suggest associations deserving further study.

Cancer in Alaskan Indians, Eskimos, and Aleuts, 1969-83: implications for etiology and control.

The authors collected and analyzed cancer incidence data for Alaska Natives (Indians, Eskimos, and Aleuts) for the 15-year period 1969-83 by ethnic and linguistic groups. Compared with U.S. whites, observed-to-expected ratios are high in more than one ethnic group for cancer of the nasopharynx, salivary gland, liver, gallbladder, and cervix. Low ratios were found for cancer of the breast, uterus, bladder, and melanoma. In Alaska, Eskimos have the highest risk for cancer of the esophagus and liver and the lowest risk for breast and prostate cancer. Risk for multiple myeloma in Indian men in Alaska exceeds not only those of other Native groups in Alaska but that in U.S. whites as well. Despite the short period studied, increases in cancer incidence over time can be documented for lung cancer in Eskimo men and women combined, and for cervical cancer, especially in Indian women.

Method for evaluating and establishing reimbursement rates for health care services authorized under the Indian Health Service contract health services regulations--selected IHS sites--IHS. Addition of sites to the IHS pilot project.

The Indian Health Service (IHS) issues this notice to inform the public that additional sites will be added to the IHS Pilot Project now being conducted in the Portland Area. This Pilot Project is to determine whether an alternative method of evaluating and establishing reimbursement rates for contract health services (CHS) will result in greater participation and lower cost to the IHS. The additional sites include the Alaska Native Medical Center and other selected locations within the Alaska Area IHS; the metropolitan Billings, Montana vicinity and other selected locations within the Billings Area IHS; and the Cherokee Service Unit, within the Nashville Area IHS.

Geographic distribution, supply, and need for generalist physicians in Alaska.

This study provides the first comprehensive description of Alaska's geographic distribution of generalist physicians relative to population. All 443 generalist care physicians (family, general, general internal medicine, and pediatric) or their office managers were questioned about their specialties, ZIP codes, employers, populations served, and hours spent per week offering direct patient care. The results indicated a 30% overall shortage of generalist physicians for the state, representing roughly 141 full-time-equivalent generalists relative to national practice patterns and trends of health maintenance organizations. Of 17 primary health care areas, including the Anchorage area, 15 showed a need for additional generalist physicians. Most areas had a 20 to 40% shortage. Concerns about transportation and financial barriers to access to care, especially in remote regions, were raised. Other needs emphasized included knowledge of contributions of midlevel health care professionals, Alaska Native versus non-Native care, efforts to train and retain physicians in Alaska, and the need for longitudinal tracking of practice patterns.
