Abstract
AIM: To investigate the historical changes in survival with diabetes in elderly people with diabetes. RESEARCH DESIGN AND METHODS: We analyzed 6504 deaths (44.5% males) registered in a large urban population, aged ≥65 years, and deceased between 1943 and 2009. We split the analysis into three time periods according to year of death: 1943-1965, 1966-1988 and 1989-2009. The parallel changes in the corresponding general population were available. RESULTS: The mean age at diabetes onset was 70.8 ± 4.7 years, with mean disease duration at death 7.5 ± 5 years, and mean age at death 78.3 ± 5.9 years. The mean survival loss due to diabetes (expected minus observed survival) was 4.5 ± 5.1 years (4.9 ± 5.1 years for females versus 4.1 ± 5.2 years for males, p<0.001). The mean disease duration at death was 6.4 ± 5.7 years in the period 1943-1965, followed by a significant (p=0.019) rise to 7 ± 5 years in 1966-1988, and 8.3 ± 4.9 years (p<0.001) in 1989-2009. There was a significant increase in coronary heart disease and stroke, and a significant decrease in infections and end-stage renal disease as causes of death. CONCLUSIONS: We found a significant increase in age at onset and survival with diabetes leading to a significant increase in age at death. Females had a higher survival loss due to diabetes compared with males.
