The mortality of a complete cohort of 1506 French asbestos cement workers employed for at least five years is related to the time elapsed since first exposure. The mortality from all causes (analysed by the "man-years method") has been found to be above normal only in those subjects employed for more than 20 years, with more than 35 years of follow up. Standardised mortality ratios for cancers of all sites (ICD 140-209) and pulmonary cancer (ICD 162-163.0) have been assessed in subjects whose first exposure dates go back more than 20 years. Mortalities from cancer of all sites and from pulmonary cancer have been detected in excess in workers employed for more than 20 years and originally hired when aged 25 or under.
一个由1506名受雇至少五年的法国石棉水泥工人组成的完整队列的死亡率与首次接触以来所经过的时间有关。通过“人年法”分析发现,只有那些受雇超过20年且随访超过35年的受试者,其全因死亡率高于正常水平。对首次接触日期可追溯到20多年前的受试者评估了所有部位癌症(国际疾病分类140 - 209)和肺癌(国际疾病分类162 - 163.0)的标准化死亡率。在受雇超过20年且最初雇佣时年龄在25岁及以下的工人中,发现所有部位癌症和肺癌的死亡率均过高。
