A cross-sectional study was carried out in Cornellà with type II diabetic patients to assess their prevalence of microangiopathy and their major risk factors. The study included 297 patients (102 males and 197 females) with a mean age of 61 years. In 45.5% of cases some feature of microangiopathy was found: 35% had peripheral vascular disease; 24.5% had coronary artery disease, and 7.1% cerebrovascular disease. The variables associated with this complication were investigated with the logistic regression technique. A significant association was found between microangiopathy as a whole and the duration of diabetes mellitus, age and smoking. Peripheral vascular disease was associated with age, clinical duration and male sex; coronary artery disease was associated with male sex and the mean level of blood triglycerides, and cerebrovascular disease was associated with age.
