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.
Conclusion:
This is the first report of COPD mortality stabilization in Brazil since 1980.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
