title: Impact of Anxiety Disorders on Mortality for Persons With Diabetes: A National Population-Based Cohort Study.
abstract: Most studies of the relationship between psychiatric disorders and mortality in patients with diabetes mellitus (DM) have focused on the role of depression.
  
  
  
  The aim of this study was to investigate the impact of anxiety disorders (ADs) on mortality in persons with DM in Taiwan.
  
  
  
  We used Taiwan׳s National Health Insurance claims database interlinked externally with Taiwan׳s Death Registry to study mortality in diabetic patients with and without ADs during the study period 2000-2004. Five-year survival cures were calculated using the Kaplan-Meier method for DM with ADs and DM without ADs. Cox regression analysis was used to analyze the predictive factors for DM mortality.
  
  
  
  We identified 5685 persons with DM, including 732 (12.88%) who also had ADs. The 5-year survival was longer for diabetic patients with ADs than those without it. A higher risk of mortality was found in diabetic patients who were male. It was also higher for those who were 45-64 years old and ≥65 years old, those who resided in rural areas, those who had incomes <US$ 666 (NT$ 20,000) or were living on dependent incomes. ADs were found to confer a lower risk of mortality regardless of diabetes type.
  
  
  
  ADs confer some protection from mortality in patients with DM. Our findings add valuable epidemiological information from a different ethnic population.
