This study sought to evaluate the short-term impact of national smoke-free workplace legislation on employee exposure to environmental tobacco smoke at work and on employee smoking habits.
We performed 2 cross-sectional studies in 9 medium-sized and large Finnish workplaces, before and after implementation of national smoke-free workplace legislation. We assessed tobacco smoke exposure via questionnaire and indoor air nicotine measurements.
Exposure to environmental tobacco smoke declined considerably after the legislation was implemented. Tobacco consumption among smokers diminished. Nicotine concentrations fell significantly.
Legislation was more efficient than voluntary workplace-specific smoking restrictions in reducing passive smoking and cigarette consumption.
本研究旨在评估国家无烟工作场所立法对员工工作时接触环境烟草烟雾及员工吸烟习惯的短期影响。
在芬兰9个大中型工作场所实施国家无烟工作场所立法之前和之后,我们进行了两项横断面研究。我们通过问卷调查和室内空气尼古丁测量来评估烟草烟雾暴露情况。
立法实施后,接触环境烟草烟雾的情况大幅下降。吸烟者的烟草消费量减少。尼古丁浓度显著降低。
在减少被动吸烟和香烟消费方面,立法比针对特定工作场所的自愿吸烟限制更为有效。
