The impact of tobacco legislation and exposure to environmental tobacco smoke (ETS) in bars and restaurants were assessed in a national survey.
Questionnaire surveys among restaurant workers were conducted in 2007 before the smoking ban, and in 2009.
The exposure to ETS decreased significantly after the launch of the 2007 smoke-free law. During 2007-2009, the prevalence of those restaurant workers with no exposure increased from 54% to 82% (P-value < 0.0001), and among bartenders from 10% to 70% (P < 0.0001). Employees exposed daily for more than 4 hr decreased from 24% to 4% (P < 0.0001) and from 67% to 9% among bartenders (P < 0.0001). The prevalence of respiratory symptoms decreased from 18% to 4% (P < 0.0001) and of eye symptoms from 23% to 6% (P < 0.0001).
The reform of tobacco legislation in 2007, which prohibited smoking in restaurants and bars, significantly decreased the exposure to ETS and the prevalence of symptoms among restaurant workers.
本研究通过全国性调查，评估了烟草立法的影响以及酒吧和餐厅环境烟草烟雾（ETS）暴露情况。
于 2007 年（禁烟令实施前）和 2009 年对餐厅工作人员进行问卷调查。
2007 年无烟法律实施后，ETS 暴露明显减少。2007-2009 年期间，无 ETS 暴露的餐厅员工比例从 54%增加到 82%（P 值 < 0.0001），调酒师从 10%增加到 70%（P < 0.0001）。每天暴露于 ETS 4 小时以上的员工比例从 24%降至 4%（P < 0.0001），调酒师从 67%降至 9%（P < 0.0001）。呼吸道症状的发生率从 18%降至 4%（P < 0.0001），眼部症状从 23%降至 6%（P < 0.0001）。
2007 年餐厅和酒吧禁烟法规的改革，显著降低了 ETS 暴露和餐厅员工症状的发生率。
