Trends of lung cancer mortality in Mexico.
Lung cancer (LC) is one of the most important public health problems in 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 rate ratio of lung cancer mortality in 31 states in Mexico, taking Mexico City as a reference by means of a Poisson model. A strong linear regression model was used to evaluate the rate, where the dependent variable was LC mortality rate and the independent variable the year observed. In 15 years, 73,807 deaths from LC were reported, with an increase in mortality from 5.01 - 7.25 per 100,000 inhabitants. Mortality increases significantly after 60 years of age (B not equal to 0), p<.05) in 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 higher 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 10,000 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 restricted in squares and public spaces, and the risks should be announced on cigarette packages, among other measures. With respect to other emergent risk factors, the sources of industrial pollution and toxic emissions should be regulated.
