P1.01-052 - Lung Cancer Mortality in Mexico, 1990-2014 (ID 5810)
14:30 - 15:45 | Author(s): L. Tirado
- Abstract
Background:
Mortality from lung cancer ranks first in men and third in women in Mexico. We aim to assess the mortality rate from lung cancer in the Mexican population during the period from 1990 through 2014.
Methods:
In this longitudinal study we analyzed the mortality rate of lung cancer, adjusted for age, sex and degree of marginalization. The mortality rate was adjusted applying the direct method. In adittion, we used the 2010 Mexican Population,which was taken from the Population and Housing Census. Deaths were taken from the mortality database of the Ministry of Health of Mexico. The degree of marginalization of the population was made based on the marginality index established by the National Population Council, it includes five categories of marginalization: Very low, low, medium, high and very high. The 33 states of the Mexican Republic are divided into these categories, approximately being six to seven in each. Finally, the annual percentage change was calculated.
Results:
During the study period a decrease we observed a decrease in the lung cancer mortality rate adjusted for age and gender. Thus, the rate in 1990 was higher (110 deaths per 100,000 population), which decreased to 90 per 100,000 in 2014, representing a decrease of more than 15%. In relation to gender we observed a decrease in the mortality rate for both genders. In addition, the mortality rate in women was three times lower from that among men througout the whole period of study. Nonetheless, we observed a slight increasing trend for women in the last years. Regarding the marginalization index we observed that the highest mortality rates occur in the states that comprise the categories with low and very low marginalization. Moreover, decline in mortality was also observed in those categories, unlike the categories of high and very high marginalization, where a slightly increase was observed during the period of study.
Conclusion:
Mortality from lung cancer has declined during the studied period, a situation that may be due to various situations such as diagnosis at earlier clinical stages or treatments more effectively, or under registry of mortality in the states that make up the categories with high or very high marginalization. Such situations must be studied in greater depth to identify the causes for the decline in mortality from lung cancer.
