Abstract
Background. Chronic obstructive pulmonary disease (COPD) is characterized by airflow
limitation that is not fully reversible. Changes in classification have a major impact on
reported mortality rates.
Methods. Between 1980 and 2002, 230,463 COPD cases were studied (age group
35 94 years); 134,579 men; 95,884 women.
Results. The crude mortality rate varied from 37 (1980) to 61 per 100,000 men (2002),
(increase: 65%). The crude mortality rate for females increased from 27 (1980) to 43
deaths per 100,000 women (2002), (increase: 56%). The trends of the absolute values by
birth year and age groups are higher as age increases. As age of death comes down and
the birth cohort increases, the absolute values decrease. The Mexican states located in the
northern and central areas present a higher risk for dying. There is an increment coefficient
of 93 cases per increment year in males (age group 35–74), and 61 cases per increment year
in females (age group 35–74 years). For the age group 35–94 years, the annual increase
for males is 288 cases. These results were statistically significant, and the regression
model was validated by residual analysis.
Conclusions. The oldest cohorts of the studied population showed the highest COPD
mortality absolute values. The geographic risk of dying from COPD is concentrated in
two regions: a) the three Mexican states of higher economic income at the northern frontier
to the U.S. and b) those Mexican states surrounding the main producer of tobacco
(Nayarit). 2005 IMSS. Published by Elsevier Inc.
