While NIDDK is the lead IC for diabetes research, diabetes research is distributed among many ICs
Discuss complications and economic costs associated with diabetes. Note that CVD accounts for 2/3 of deaths in DM and rate of CVD is decreasing in general population but increasing in those with DM.
Ominous implications if epidemic of diabetes is not checked.
The ABC’s of diabetes campaign is bringing information about interventions for those with diabetes proven successful in clinical trials in preventing diabetes complications to providers and patients.
One of our most important earlier findings was the greatly increased risk of diabetes in offspring of diabetic mothers compared with nondiabetic or prediabetic mothers, as shown here. The much greater risk in the offspring of diabetic mothers than prediabetic mothers, both of whom presumably carry diabetes susceptibility genes, suggested a major effect of diabetes In utero on the subsequent risk in the offspring.
--The fact that there is an epidemic of type 2 diabetes in the U.S. is certainly no secret. 15 million people have type 2 diabetes. --About 800,000 new cases are diagnosed each year. --Diabetes costs the Nation $100 billion per year in direct and indirect costs of the disease. --In the past 10 years, diabetes has spread throughout the nation. The map on the left from 1990 shows four states with greater than 6 percent prevalence in the darkest blue. By 2000, this prevalence rate had taken over the country. --Increased obesity and sedentary lifestyle contributing to epidemic of type 2.
The Diabetes Prevention Program was initiated in 1994 with a planning phase that lasted approximately 18 months. Recruitment was initiated in mid-1996 and completed 3 years later, ahead of schedule. Although the originally planned end of the treatment phase of the study was to be in mid- 2002, we are ending this phase of the DPP now, approximately 1 year ahead of schedule. The decision to terminate the treatment phase of the DPP early was based on the recommendation of the independent Data Monitoring Board that oversaw the performance of the study and examined the study data on a regular basis. They concluded in May of this year that the DPP had answered the major study questions.
