在许多无明显影响寿命因素的工矿人群死亡流行病学研究中,观察到健康工人效应(HWE)。与一般人群比较时,此效应可作为描述等种作业强度下的低死亡率指标。本文的目的就是要在日本的大型机械公司中,估计现在作业人群的 HWE,并且要提出产生这种效应的可能因素.日本的钢铁联合 In many epidemiological studies of deaths in industrial and mining populations that have no significant impact on life-span factors, a health worker effect (HWE) has been observed. When compared with the general population, this effect can be used as a low mortality index for describing the intensity of such operations. The purpose of this paper is to estimate the HWE of the current working population among the large machinery companies in Japan, and to propose possible factors for this effect.
