Researchers have detected a drop in the occurrence of problems related to cardiovascular disease in adult patients with diabetes, but the overall rate of cardiovascular disease among this group in the United States remains 2 times higher than in patients without diabetes. The current study analyzed data for 2 groups of individuals, aged 45 to 64, who were enrolled in the Framingham Heart Study. Group 1 included 4118 individuals who participated from 1950 to 1966, while group 2 included 4063 individuals who participated from 1977 to 1995. In the first group, 113 individuals had diabetes, while the second group had 317 individuals with the condition.
The results of the study showed that adults in the later time period had a 50% reduction in the incidence of cardiovascular disease, compared with the individuals in the earlier time period. (The findings were reported in the Journal of the American Medical Association, November 24, 2004.)
