Average annual changes (vma) of obesity percentagens were estimated for que periods 2006-2011 and 2006-2021.Results: During the study period, the percentagens of obesity increased in all state capitals and in the Federal Distrit. The estimated vma for the reference periods reveal a decrease in the upward trend in most state capitals and the Federal Distrit. Greater decreases are recorded in Curitiba (0.86 t0 0.47/year), Fortaleza (1.27 to 0.60/year), Manaus (1.39 to 0.87/year), Rio Branco (1.51 to 0.73/year), Rio de Janeiro (1.02 to 0.65/year), etc.Conclusion: There is a decrease in the trend of increasingg obesity percentagens in most state capitals, except in Belem, Belo Horizonte and DF.
