title: Changes in the prevalence of diabetes mellitus in bulgaria (2006-2012).
abstract: OBJECTIVE
  The aim of this study was to compare two nationwide cross-sectional studies of diabetes prevalence in Bulgaria (2006 and 2012) and to assess its dynamics.
  
  
  METHODS
  The two studies included 2396 and 2033 subjects, respectively. The International Diabetes Federation (IDF) diagnostic criteria were applied, and the data were weighed for type of settlement and age.
  
  
  RESULTS
  Diabetes prevalence was found to be 7.9% in 2006 and 9.55% in 2012, P = 0.06, showing an increase of 20.9%. The absolute increase was 0.9% in the females and 2.3% in the males (P < 0.09). The increase was the largest in those aged 50-59: [9.4%, 2006 vs. 15.7%, 2012, P < 0.01]. Diabetes prevalence increased in the 20-60-year olds by 6.8% and decreased in the elderly by 6.1%. Obesity increased from 26.7 to 32.7%, P < 0.02.
  
  
  CONCLUSIONS
  A significant increase in diabetes prevalence was found that necessitates healthcare measures and resources for community-based awareness and prevention programs.
