title: Trends in prevalence of overweight and obesity in adults in 26 Brazilian state capitals and the Federal District from 2006 to 2012.
abstract: OBJECTIVE
  To describe the annual evolution of the prevalence of overweight and obesity in the adult population of the 26 Brazilian state capitals and the Federal District from 2006 to 2012.
  
  
  METHODS
  Annual interviews (around 54,000 per year) from VIGITEL (Surveillance System of Risk and Protective Factors for Chronic Non-Communicable Diseases through Telephone Interviews) were used. Self-reported weight and height were used to estimate body mass index and nutritional status. Prevalence estimates of overweight and obesity are presented according to gender, age and schooling and to each city. Linear regression model was used to evaluate the time trend of prevalence.
  
  
  RESULTS
  Prevalence of overweight in adults in the 27 cities monitored by VIGITEL increased from 43.2% (2006) to 51.0% (2012), with an annual increase rate of 1.37%. Prevalence of obesity increased from 11.6% to 17.4%, with an annual increase rate of 0.89%. The study showed a statistically significant increase in the prevalence of overweight in all cities, and for both genders, all age groups and all levels of schooling. Similar trends were also verified for obesity.
  
  
  CONCLUSIONS
  If the trends verified from 2006 to 2012 are maintained, in ten years, around two-thirds of the adults in Brazilian state capitals will be overweight, and a quarter will be obese. This perspective requests urgent response from government and intersectoral actions to combat the obesogenic environment.
