OBJECTIVE: To investigate the prevalence rates of chronic diabetic complications and their risk factors. METHODS: We analyzed retrospectively the clinical and laboratory data on the 24,496 in-patients from 30 provinces, municipalities, and autonomous regions during January 1, 1991 to December 31, 2000. RESULTS: The prevalence rates of chronic diabetic complications and related macrovascular diseases were 31.9% for hypertension, 12.2% for cerebrovascular diseases, 15.9% for cardiovascular diseases, 5.0% for lower extremity vascular diseases, 34.3% for retinopathy, 33.6% for nephropathy, and 60.3% for neuropathy, total rate of chronic diabetic complications and macrovascular diseases was 73.2%. The risk factors related to all kinds of chronic diabetic complications and macrovascular diseases were age, illness duration, and systolic blood pressure. CONCLUSIONS: The prevalence rates of chronic diabetic complications of in-patients with diabetes mellitus are rather high, near to their level in developed countries. The controllable risk factor of chronic diabetic complications is systolic blood pressure.
