A cohort of employees at a smelter in Northern Sweden has been updated with the addition of information regarding smoking habits to evaluate the role of smoking in the occurrence of lung cancer in various job categories and employment cohorts. An updated analysis of earlier studies of the interaction between roaster work and smoking is also reported. The cohort members first employed during the period 1928-1979 have been followed up to 1 January 1988. Information regarding smoking habits for 69% of the cohort was gathered in a questionnaire study.
The prevalence of daily smoking decreased during the study period and was lower for salaried employees. The figures were, however, comparable with national figures for similar social and occupational strata. Adjustment for smoking did not alter the lung cancer gradient between employment cohorts or between job categories.
The interaction between smoking and roaster work was confirmed and the benefits from ceasing to smoke shown to be greater among the roaster workers.
瑞典北部一家冶炼厂的一组员工信息已更新，增加了吸烟习惯方面的信息，以评估吸烟在不同工作类别和就业群体中肺癌发生情况的作用。还报告了对早期关于焙烧炉工作与吸烟之间相互作用研究的更新分析。1928年至1979年期间首次受雇的队列成员一直随访至1988年1月1日。通过问卷调查收集了该队列69%成员的吸烟习惯信息。
在研究期间，每日吸烟率下降，且受薪员工的吸烟率较低。然而，这些数字与类似社会和职业阶层的全国数字相当。对吸烟情况进行调整后，就业群体之间或工作类别之间的肺癌梯度没有改变。
吸烟与焙烧炉工作之间的相互作用得到证实，并且戒烟对焙烧炉工人的益处更大。
