In retrospective occupational studies, the degree of confounding by smoking depends on variation in smoking among job-related exposure groups. We assessed the relationship between job title and smoking behavior as part of a study on occupational exposures and lung cancer.
A questionnaire on smoking was mailed to a sample of 11,986 trucking industry workers. Company records were used to gather other relevant information.
The response rate was 40.5%. Among white males, the age-adjusted prevalence of ever smoking was highest among longhaul truck drivers (67%) and lowest among clerks (44%). Smoking rates among workers with other job titles were similar.
Our results will be used to adjust for the differences in smoking among job-related exposure groups when assessing the association between particulate matter exposure and lung cancer mortality. Our study also suggests that an assessment of methods to control for smoking should be considered in the design of retrospective occupational health studies.
在回顾性职业研究中，吸烟造成的混杂程度取决于与工作相关的暴露组之间吸烟情况的差异。作为一项关于职业暴露与肺癌的研究的一部分，我们评估了职位与吸烟行为之间的关系。
向11986名运输行业工人的样本邮寄了一份关于吸烟的调查问卷。利用公司记录收集其他相关信息。
回复率为40.5%。在白人男性中，曾经吸烟的年龄调整患病率在长途卡车司机中最高（67%），在办事员中最低（44%）。其他职位的工人吸烟率相似。
在评估颗粒物暴露与肺癌死亡率之间的关联时，我们的结果将用于调整与工作相关的暴露组之间吸烟情况的差异。我们的研究还表明，在回顾性职业健康研究的设计中应考虑对控制吸烟方法的评估。
