title: Mortality trends due to chronic obstructive pulmonary disease in Brazil.
abstract: OBJECTIVE
  The purpose of this study was to update and analyze data on mortality trend due to chronic obstructive pulmonary disease (COPD) in Brazil.
  
  
  METHODS
  Initially, the specific COPD mortality rates were calculated from 1989 to 2009 using data collected from DATASUS (Departamento de Informática do SUS - Brazilian Health System Database). Then, the polynomial regression models from the observed functional relation were estimated based on mortality coefficients and study years.
  
  
  RESULTS
  We verified that the general mortality rates due to COPD in Brazil showed an increasing trend from 1989 to 2004, and then decreased. Both genders showed the same increasing tendencies until 2004 and decreased thereafter. The age group under 35 years old showed a linear decreasing trend. All other age groups showed quadratic tendencies, with increases until the years of 1998-1999 and then decreasing. The South and Southeast regions showed the highest COPD mortality rates with increasing trends until the years 2001-2002 and then decreased. The North, Northeast and Central-West regions showed lower mortality rates but increasing trend.
  
  
  CONCLUSIONS
  This is the first report of COPD mortality stabilization in Brazil since 1980.
