MORTALITY AMONG TYPE-2 DIABETIC INDIVIDUALS AND ASSOCIATED RISK-FACTORS - THE 3 CITY STUDY

The 10 year mortality experience was determined in a population-based cohort of 540 Type 2 diabetic individuals. The association between pot ential risk factors and all causes mortality was examined. Diabetes wa s not mentioned anywhere on the death certificate in 46 %. of 274 dece dents. Diseases of the circulatory system (ICD9-390-459) accounted for the majority (62 %) of deaths in this cohort. Ten-year survival was p oorer than expected for both men and women compared to the age- and se x-matched Minnesota population. Standardized mortality ratios for sele cted causes of death indicated excess for cardiovascular disease (ICD9 -390-459), coronary heart disease (ICD9 410-414) and cerebrovascular d isease. Baseline variables associated with all causes of mortality inc luded age and a history of macrovascular disease. These findings indic ate that mortality data significantly underestimate the magnitude of d iabetes and that individuals with diabetes have poorer survival than n on-diabetic individuals.
