Abstract

OBJECTIVE—The purpose of this study was to examine risk factors for mortality in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS—Baseline risk factors were measured in the EURODIAB Prospective Cohort Study with 2,787 type 1 diabetic patients (51% men and 49% women) recruited from 16 European countries. Mortality data were collected during a 7-year follow-up. RESULTS—There was an annual mortality rate of 5 per 1,000 person-years in patients with type 1 diabetes (mean age at baseline 33 years, range 15–61 years); of the total 2,787 subjects, 102 died. The final multivariable model contained age at baseline (standardized hazard ratio 1.78 [95% CI 1.44–2.20]), A1C (1.18 [0.95–1.46]), waist-to-hip ratio (WHR) (1.32 [1.14–1.52]), pulse pressure (1.33 [1.13–1.58]), and non-HDL cholesterol (1.33 [1.12–1.60]) as risk factors for all-cause mortality. Macroalbuminuria (2.39 [1.19–4.78]) and peripheral (1.88 [1.06–3.35]) and autonomic neuropathy (2.40 [1.32–4.36]) were the most important risk markers for mortality. Similar risk factors were found for all-cause, non-cardiovascular disease (CVD), unknown-cause, and CVD mortality. CONCLUSIONS—Important risk factors for the increased total and non-CVD mortality in type 1 diabetic patients are age, WHR, pulse pressure, and non-HDL cholesterol. Microvascular complications from macroalbuminuria and peripheral and autonomic neuropathy are strong risk markers for future mortality exceeding the effect of the traditional risk factors
