Overall death rates from Type 1 diabetes have reduced due to the progress made in treatment and care, yet women and African-Americans portray higher risks of mortality, according to a University of Pittsburgh Graduate School of Public Health study being presented at the 70th Scientific Sessions of the American Diabetes Association.
The results, abstract number 0326-OR, are based on the Allegheny County Type 1 Diabetes Registry, one of the largest population-based registries of the disease, which includes nearly 1,100 people diagnosed between 1965 and 1979 in Allegheny County, Pa.
As of January 2008, 26 percent of registry participants had died - a rate seven times higher than age-and sex-matched people in the general population. Participants who were diagnosed most recently (1975 to 1979) were only 5.5 times more likely to have died.
"The more recent a person was diagnosed with type 1 diabetes, the less likely they were to die, suggesting the positive impact of advances made during the last few decades," said Aaron M. Secrest, lead author of the study and a doctoral student at the University of Pittsburgh Graduate School of Public Health. "Even so, significant disparities in mortality remain and reveal a need for continuing improvements in diabetes treatment and care."
