It was conducted a study of cases and controls which included 1 060 patients with lung cancer reported to the National Register of Cancer from 1987 to 1988, and the same number of controls matched by sex, age, and place of residence. A survey was done aimed at knowing about smoking and occupational exposure to inhalation of cancerigenic agents, as well as about place of residence, type of fuel, and location of the cooker in the house during the last 40 years. The evaluation of environmental pollution at each municipality of the capital was carried out by using the "scale and weight" technique, considering the determined pollution level, the average fulfillment of the sanitary protection ratios of the stationary sources, the main character of the territory, the development of the system of public reads, and the character of the territory windward. The analysis of associations was made by conditioned multiple logistic regression. The ratios of disparity adjusted to the variables and interactions among them were calculated, as well as the corresponding intervals of confidence at 95 %. The results showed the following associations for both sexes: very strong with smoking habit and its intensity, and of less magnitude with the residence predominating in the zones of the capital with higher indexes of exposure to environmental pollution (significant in men), with the location of the cooker in a room for common use, and with the use of kerosene as fuel (no significant), there is a possible synergic effect between both variables, which is stronger among women.
