title: Prevalence, correlates, and description of self-reported diabetes in brazilian capitals - results from a telephone survey.
abstract: BACKGROUND
  The prevalence of diabetes is increasing worldwide. The objective of this study is to estimate the prevalence of self-reported diabetes in Brazilian adults and to describe its population correlates as well as the clinical characteristics of the reported cases.
  
  
  METHODS
  We analyzed basic and supplementary data of 54.144 subjects participating in VIGITEL 2011 (Surveillance System for Risk and Protective Factors for Chronic Diseases), a telephone survey based on a probabilistic sample of subjects ≥ 18 years old residing in Brazilian state capitals and the Federal District. Estimates reported are weighted so as to represent the surveyed population.
  
  
  RESULTS
  The prevalence of self-reported diabetes was 6.3% (95% CI 5.9-6.7), increasing markedly with age and nutritional status, and decreasing with level of education. Prevalence was higher among those self-declaring their race/color as black. Most cases (90%) reported the diagnosis being made at 35 years or older. The vast majority (99.8%) of self-reported cases informed having previously performed at least one glucose test, and 76% of those not reporting diabetes also informed having previously performed glucose testing. Most cases (92.6%) reported following some form of diabetes treatment, 79% taking medication.
  
  
  CONCLUSIONS
  The estimated prevalence of known diabetes found, 6.3%, is consistent with estimates given by international summaries. The additional data collected in VIGITEL 2011 regarding previous glucose testing and current treatment support the use of telephone-based information to monitor the prevalence of known diabetes in Brazilian capitals.
