title: [Epidemiological characteristics of tuberculosis patients complicated with diabetes in Shanghai].
abstract: OBJECTIVE
  To understand the epidemiological trends and characteristics of tuberculosis patients complicated with diabetes in Shanghai.
  
  
  METHODS
  All the registered tuberculosis (TB) cases from 1992 to 1997 in Shanghai were included in the analysis. The new registration rates and percentages of TB cases complicated with diabetes were calculated.
  
  
  RESULTS
  The new registration rate of the cases increased from 0.70/100,000 in 1992 to 2.10/100,000 in 1997 with an annual increase rate of 24.57%. The cases with the complication accounted for 4.86% in 1997. Diabetes tends to be more prevalent among TB patients in urban area. The greater the age, the more diabetes were found in TB patients. A significant difference was also observed between sex. Bacillary positive rate and percentage of infiltration type were higher, and cavity was more common in cases with the complication. The percentage of cases with relapse was also higher.
  
  
  CONCLUSIONS
  The complication of diabetes significantly affected the epidemiological trend of TB in Shanghai. The diagnosis of diabetes in TB patients should be enforced, and short-course chemotherapy targeting the cases should be investigated.
