title: [A nationwide retrospective analysis on chronic diabetic complications and related macrovascular diseases of in-patients with diabetes during 1991-2000].
abstract: 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.
