A nested case-control study of fatal work related injuries among Brazilian steel workers.
Objectives-To estimate the relative risk of death from work related injury in a steelworks, associated with exposure to various occupational hazards, socio-demographic factors, and medical history.
Material and methods-The study was a nested case-control design.
It was based on a cohort of men employed in the steel plant of USIMINAS, Brazil between January 1977 and August 1990, who were followed up to November 1992.
The cases were defined as all workers in the cohort who died from injury in the study period and whose death had been notified to the Brazilian Ministry of Labour as being related to work.
Four controls per case, matched to cases on year of birth, were randomly selected from among workers employed in the plant at the time of death of the matching case.
Data on potential risk factors for occupational injury were extracted from company records ; for the controls these data were abstracted for the period preceding the death of the matching case.
There were 37 deaths related to work injuries during the study period.
Four surviving workers were selected as controls for each case, but for eight the personnel records were incomplete, leaving 140 controls in all.
Significantly increased risk of fatal injury related to work was associated with exposure to noise, heat, dust and fumes, gases and vapours, rotating shift work, being a manual worker, and working in the steel mill, coke ovens, blast furnaces, and energy and water supply areas. (...)
