A search of the literature has revealed compelling evidence that race and ethnicity correlate with persistent, and often increasing, health disparities among U.S. populations. Indeed, despite notable progress in the overall health of the United States, there are continuing disparities in the burden of illness and death experienced by African Americans, Hispanics, American Indians and Alaska Natives, and Pacific Islanders, compared to the U.S. population as a whole.
In a February 21, 1998 address to the nation, President Clinton identified race and ethnicity-related disparities in health outcomes as a major public health issue in the United States and called for their elimination by the year 2010. The elimination of these disparities then became the major goal of the U.S. Department of Health and Human Services' Healthy People 2010. These initiatives followed years of work by multiple agencies and investigators that has shown that ethnic minority populations in the United States experience persistent problems accessing health care, receiving high quality health care, and achieving health outcomes.
President Clinton's Initiative to eliminate racial and ethnicity related disparities in health focused on six major areas. These are diabetes, cardiovascular disease (including stroke), breast and cervical cancer, HIV-related disease, infant mortality, and immunization rates. These areas were chosen not only because of differences in outcomes across target populations but also because primary and secondary prevention strategies have been conclusively shown to be effective in improving these outcomes.
Diabetes Mellitus is a chronic disease that affects 6% of the
U.S. population. With over 625,000 new cases diagnosed each year, significant
morbidity and mortality, and related health care expenditures of $100 billion
yearly, diabetes continues to be a major health care concern. Patients with
diabetes are at an increased risk of multi-system complications. Recent results
from landmark studies such as DCCT (Diabetes Control and Complications Trial)
Diabetes Mellitus is a chronic systemic condition that constitutes a major public health problem. Diabetes is a serious disease that can lead to kidney failure, blindness, stroke, heart disease, and lower limb amputations and is the fourth-leading cause of death in the United States. It has been estimated that 16 million diabetics live in the United States, 90-95 percent of whom have Type 2 Diabetes Mellitus and 5-10 percent Type 1 Diabetes Mellitus, and because of its frequency, it is probably the most important metabolic disease affecting humankind.
Researchers continue to search for the cause or causes of diabetes and ways to prevent and cure the disorder. Scientists are looking for genes that may be involved in Type 2 diabetes and Type 1 diabetes. Some genetic markers for Type 1 diabetes have been identified, and it is now possible to screen relatives of people with Type 1 diabetes to see if they are at risk for diabetes. For Type 2 diabetes, the focus is on ways to prevent diabetes. Preventive approaches include identifying people at high risk for the disorder and encouraging them to lose weight, exercise more, and follow a healthy diet. The Diabetes Prevention
Program, another new National Institute of Diabetes and Digestive and Kidney
Disease of the National Institutes of Health (NIDDK) project, will focus on
preventing the disorder in high-risk populations.
The NIDDK supports basic and clinical research in its own laboratories and in research centers and hospitals throughout the United States. It also gathers and analyzes statistics about diabetes. Other institutes at the National Institutes of Health also carry out research on diabetes-related eye diseases, heart and vascular complications, pregnancy, and dental problems.
Other Government agencies that sponsor diabetes programs are the Centers for Disease Control and Prevention, the Indian Health Service, the Health Resources and Services Administration, the Bureau of Veterans Affairs, and the Department of Defense. Many organizations outside of the Government support diabetes research and education activities. These organizations include the American Diabetes Association, the Juvenile Diabetes Foundation International, and the American Association of Diabetes Educators (see the URLs at the beginning of this lecture).
In recent years, advances in diabetes research have led to better ways to manage diabetes and treat its complications. Major advances include:
