[Studies on mortality in diabetics in a circumscribed region: age and death, length of diabetes and causes of death].

Studies were carried out in regard to the age at death, duration of diabetes mellitus at the time of death and cause of death in an unselected evaluation of the findings in all 1694 diabetics who died in Erfurt and environs over an 11-year period. The The mean age of the patients at the time of death was 70.6 years, with virtually no difference between the sexes. Only six patients died prior to the age of 40. In accordance with the age structure of diabetics in a circumscribed area, the average survival time was 6.5 years. The interval between the first manifestation of the disease and death was 0 to 4 years in 45% of the patients; only every fifth patient survided for 10 or more years. These results are interpreted as being a reflexion of the frequent incidence of preceding or simultaneously-occuring atherosclerosis in these diabetics. Cardiovascular incidents affecting, above all, the coronary and cerebral vessels, account for about 60% of the deaths. Differences between these results and other statistical analyses can be explained on the basis of the unselective nature of the case material in the present study which was, moreover, collected in a defined region over a definite period of time.
