The Swedish Cancer-Environment Register was used to study the relation between occupation and lung cancer risk during the period 1961-79 in 1.6 million men aged 30-64 years in 1960. By adding information concerning smoking habits from a sample of 1% of the Swedish population, smoking-adjusted standardized incidence ratios (SIR) were estimated for different occupational categories according to the population census of 1960. Smoking-adjusted excess risks (p less than 0.01) were found in assemblers and machine erectors, drivers, miners, packers and longshoremen as well as in sheetmetal workers. Significantly fewer lung cancer cases than expected were seen in artists and writers, chemical and cellulose workers, farmers, farm workers, forestry workers, public administrators and in teachers. As a result of a high prevalence of smoking, the smoking-adjusted SIR was markedly lower than the unadjusted SIR in artists and writers, drivers, mechanics and repairmen, members of the armed forces and painters. The opposite situation was seen for clergy, farmers and forestry workers.
瑞典癌症-环境登记处用于研究1960年年龄在30至64岁的160万男性在1961年至1979年期间职业与肺癌风险之间的关系。通过从1%的瑞典人口样本中添加有关吸烟习惯的信息，根据1960年的人口普查，估算了不同职业类别的吸烟调整标准化发病率（SIR）。在装配工和机器安装工、司机、矿工、包装工和码头工人以及钣金工人中发现了吸烟调整后的超额风险（p<0.01）。在艺术家和作家、化学和纤维素工人、农民、农场工人、林业工人、公共管理人员和教师中，肺癌病例明显少于预期。由于吸烟率高，艺术家和作家、司机、机械师和修理工、武装部队成员和油漆工的吸烟调整SIR明显低于未调整的SIR。神职人员、农民和林业工人则出现相反的情况。
