Lung cancer (LC) is one of the most important public health problems i
n the world; 1,035,000 annual deaths are estimated each year and more
than 80% of these are attributed to tobacco. The trend of lung cancer
mortality in Mexico City from 1979 - 1993 was determined, as was the r
ate ratio of lung cancer mortality in 31 states in Mexico, taking Mexi
co City as a reference by means of a Poisson model. A strong linear re
gression model was used to evaluate the rate, where the dependent vari
able was LC mortality rate and the independent variable the year obser
ved. In 15 years, 73,807 deaths from LC were reported, with an increas
e in mortality from 5.01 - 7.25 per 100,000 inhabitants. Mortality inc
reases significantly after 60 years of age (beta not equal 0, p<.05) i
n men and in women. Mortality from LC was 70% in men, and more than 60
% of deaths were reported after 65 years of age. Mortality risk is hig
her in the northern states of the country (e.g., Sonora, RR=2.40) than
in the southern region (e.g., Oaxaca RR=0.40). In Mexico, almost 10,0
00 deaths by LC are estimated for the year 2010. Therefore, changes in
lifestyle should be encouraged in order to decrease the smoking habit
. The governmental tax on cigarettes should be increased, smoking rest
ricted in squares and public spaces, and the risks should be announced
on cigarette packages, among other measures. With respect to other em
ergent risk factors, the sources of industrial pollution and toxic emi
ssions should be regulated.
