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.它是以1977年1月至1990年8月期间在巴西USIMINAS钢铁厂就业的一批男子为基础的，对他们的跟踪一直到1992年11月。这些病例被定义为在研究期间因受伤而死亡的队列中的所有工人，其死亡已被通知巴西劳动部与工作有关。每个病例有四个对照，与出生年份的病例相匹配，从匹配病例死亡时在工厂工作的工人中随机选择。从公司记录中提取了有关职业伤害潜在风险因素的数据;对于对照组，这些数据是在匹配病例死亡前一段时间内提取的。结果-研究期间有37例与工伤相关的死亡。每种情况下选择4名幸存的工人作为对照，但8名工人的人事记录不完整，总共留下140名对照。与工作相关的致命伤害风险显著增加与接触噪音、热量、灰尘和烟雾、气体和蒸汽、轮班工作、体力劳动者以及在钢厂、焦炉、高炉以及能源和供水领域工作有关。与工作有关的致命伤害的危险性随着噪声（P（趋势）= 0.004）和高温（P
Objectives-To estimate the relative risk of death from work related injury in a steelworks, associated with exposure to various occupational hazards, sociodemographic 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 hom company records; for the controls these data were abstracted for the period preceding the death of the matching case.Results-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. Risk of fatal injury related to work increased with intensity of exposure to noise (P (trend) = 0.004) and heat (P
