In a hospital-based case-control study, 316 lung cancer cases and 536 controls were interviewed for their occupational, smoking, passive smoking, cancer in the family and residential histories as well as social economic status, by trained interviewers, using a standardized questionnaire. Cases and controls were matched by hospital, sex and age. The study was carried out between 1st July 1990 and 31st January 1991 in 14 hospitals in the Metropolitan Region of S. Paulo, the most highly industrialized and urbanized region in Brazil. Score criteria were developed for the ordering of the individuals of the study by occupational exposure to know carcinogens to the lung, in order to evaluate this exposure during the occupational life of each person. The criteria accumulated information on exposure to carcinogens as regards type, sector of work and time in each employment. The unconditional logistic regression analysis showed an odds ratio of 1.97 (95% IC: 1.52 to 2.55) for the highest exposure group. This result showed that workers linked to the production sectors of several industries have about twice the risk of developing lung cancer as workers involved in non-industrial activities.
