Abstract
SANTOS ARRONTES, Daniel et al. Tobacco consumption and bladder cancer mortality in Spain. Arch. Esp. Urol. [online]. 2006, vol.59, n.2, pp.141-145. ISSN 0004-0614.
Objectives: To establish the trend of the bladder cancer adjusted mortality and its correlation with tobacco consumption in different Spanish Autonomic Communities over a 15 year period. Methods: We evaluate the trends of mortality rates associated with bladder cancer between January 1st 1989 and December 31st 2002 in the geographic area of Spain, as well as the tendency of tobacco consumption. Demographic and mortality data were obtained from the National Institute of Statistics, and consumption data were obtained from the Commissioner for the Tobacco Market in the Spanish Economics and Finances Ministry. We calculate the average number of cigarettes (1 package = 20 cigarettes) consumed per person; we also calculate bladder cancer adjusted mortality rates, presented as number of deaths for that cause per 100.000 persons year, and the ratio between number of packages of cigarettes consumed and adjusted mortality rate. We determine the yearly percentage increase over the whole period of study for both the mortality rate and tobacco consumption, and evaluate their correlation by the Spearmans coefficient. Results: Mean adjusted bladder cancer mortality rate over the period of study was 9.4 deaths per 100.000 habitants year, and mean tobacco consumption was 109.7 packages per person year. There has been a 2.05% yearly increase of bladder cancer associated mortality, mean cigarette consumption has diminished 1.3% per year. The Spearmans test did not show any correlation between both factors (p = 0.722). Conclusions: Despite preventive measures for tobacco addiction in our country, there is an important continuous consumption. The increase in the incidence of bladder cancer does not seem to be related with higher tobacco consumption currently, therefore it may be related with other genetic or environmental factors.
