[BDSP. Notice produite par INIST BJR0xhq6. Diffusion soumise à autorisation]. Objectives. In a cohort of 21 816 Brazilian steelworkers we found mortality from motor-vehicle injury was twice that in the State population. A nested case-control study was therefore undertaken to investigate possible socio-demographic, medical and occupational risk factors for this increased risk. Methods. Cases were defined as all steelworkers in the cohort who died of motor-vehicle injury during employment in the period 1977-1992. For each case, four controls were selected at random from workers in the cohort who were employed at the time of death of the case, and who were born in the same year as the case. Data on socio-demographic factors, and medical and occupational histories were obtained from personnel, industrial hygiene and medical records, and the relation of these factors to risk of motor-vehicle injury was analysed using conditional logistic regression. Results. In a multivariate analysis, the risk of death from motor-vehicle injury was independently associated with being unmarried (odds ratio [OR] compared to married=3.21,95% confidence interval [Cl] : 1.84-5.5g), having a hearing defect (OR=2.28,95% Cl : 1.10-4.74) and exposure to moderate (OR=1.71,95% Cl : 1.03-2.83) or high (OR=2.00,95% Cl : 1.18-3.39) levels of noise at work. The risk of fatal motor-vehicle injury increased with intensity of occupational noise exposure (P=0.004). Conclusions. (...)
