Patterns of alcohol consumption varied substantially between the two reservation-based AI populations, the geographically dispersed sample of AIs, and the US reference population. Careful consideration of these variations may improve the effectiveness of alcohol prevention and treatment programs as they may reflect important underlying differences in the cultures of alcohol consumption across these populations.

OBJECTIVEAmerican Indians and Alaska Natives are 2.3 times more likely to have diabetes than are individuals in the U.S. general population. The objective of this study was to compare morbidity among American Indian and U.S. adults with diabetes.RESEARCH DESIGN AND METHODSWe extracted demographic and health service utilization data for an adult American Indian population aged 18–64 years (n = 30,121) served by the Phoenix Service Unit from the Indian Health Service clinical reporting system. Similar data for a U.S. population (n = 1,500,002) with commercial health insurance, matched by age and sex to the American Indian population, were drawn from the MartketScan Research Database. We used Diagnostic Cost Groups to identify medical conditions for which each individual was treated and to assign a risk score to quantify his or her morbidity burden. We compared the prevalence of comorbidities and morbidity burden of American Indian and U.S. adults with diabetes.RESULTSAmerican Indians with diabetes had significantly higher rates of hypertension, cerebrovascular disease, renal failure, lower-extremity amputations, and liver disease than commercially insured U.S. adults with diabetes (P < 0.05). The American Indian prevalence rates were 61.2, 6.9, 3.9, 1.8, and 7.1%, respectively. The morbidity burden among the American Indian with diabetes exceeded that of the insured U.S. adults with diabetes by 50%.CONCLUSIONSThe morbidity burden associated with diabetes among American Indians seen at the Phoenix Service Unit far exceeded that of commercially insured U.S. adults. These findings point to the urgency of enhancing diabetes prevention and treatment services for American Indians/Alaska Natives to reduce diabetes-related disparities.

OBJECTIVES: The purpose of this study was to examine how pharmaceutical expenditures vary by age and the presence of chronic health problems. METHODS: Data from the 1987 National Medical Expenditure Survey were used to obtain nationally representative estimates of outpatient prescription drug expenditures for the noninstitutionalized population and the fraction of total health expenditures used to purchase medications for age-chronic disease population subgroups. RESULTS: Although the elderly make up 12% of the population, they account for 34% of total pharmaceutical expenditures. Pharmaceutical expenditures are 9% of total expenditures for children, 13% for nonelderly adults, and 23% for the elderly. Among nonelderly adults, approximately one third have at least one chronic condition and account for over two thirds of drug expenditures. Among the elderly, 36% have three or more chronic conditions and account for 57% of drug expenditures for this group; 41% of total drug expenditures are for cardiovascular or renal drugs. CONCLUSIONS: Significant pharmaceutical spending is for treatment of chronic conditions, which subjects insurance coverage to adverse selection and could affect the design of prescription drug benefit packages. Current enrollees in Medicare risk management plans who have drug benefits may face significantly higher out-of-pocket expenses for pharmaceuticals if capitation rates are cut as a means of controlling Medicare program expenditures.
