目的 比较爱尔兰共和国和北爱尔兰共和国引入无烟工作场所立法前后酒吧工作人员的二手烟暴露情况和呼吸系统健康情况。干预和控制区域立法前后的设计比较。在共和国的三个地区（干预）和北爱尔兰的一个地区（对照）设置公共场所。参与者 329 名酒吧工作人员参加基线调查； 249 人 (76%) 一年后跟进。其中，158 人在基线和随访时均不吸烟。主要结果测量唾液可替宁浓度、自我报告的二手烟暴露情况以及呼吸道和感觉刺激症状。结果 在共和国内不吸烟的酒吧工作人员中，无烟法实施后唾液可替宁浓度下降了 80%（从中位数 29.0 nmol/l（95% 置信区间 18.2 至 43.2） nmol/l）下降至 5.1 nmol/l（2.8 至 13.1 nmol/l），而同期北爱尔兰下降了 20%（从中位数 25.3 nmol/l（10.4 至 59.2 nmol/l）下降至 20.4 nmol/l（13.2 至 33.8 nmol/l））。自我报告的二手烟暴露变化与可替宁浓度的变化一致。 在共和国，报告任何呼吸道症状的人数显着下降（下降 16.7%，从 - 26.1% 到 - 7.3%），但在北爱尔兰则不然（差异为 0%，从 - 32.7% 到 32.7%）。调整混杂因素后，爱尔兰共和国的呼吸道症状下降幅度明显大于北爱尔兰，可替宁浓度的下降幅度是北爱尔兰的两倍。 结论 爱尔兰共和国的无烟法保护 禁止吸烟的酒吧工作人员避免接触二手烟。
Objectives To compare exposure to secondhand smoke and respiratory health in bar staff in the Republic of Ireland and Northern Ireland before and after the introduction of legislation for smoke-free workplaces in the Republic.Design Comparisons before and after the legislation in intervention and control regions.Setting Public houses in three areas in the Republic (intervention) and one area in Northern Ireland (control).Participants 329 bar staff enrolled in baseline survey; 249 (76%) followed up one year later. Of these, 158 were non-smokers both at baseline and follow-up.Main outcome measures Salivary cotinine concentration, self reported exposure to secondhand smoke, and respiratory and sensory irritation symptoms.Results In bar staff in the Republic who did not themselves smoke, salivary cotinine concentrations dropped by 80% after the smoke-free law (from median 29.0 nmol/l (95% confidence interval 18.2 to 43.2 nmol/l) to 5.1 nmol/l (2.8 to 13.1 nmol/l) in contrast with a 20% decline in Northern Ireland over the same period (from median 25.3 nmol/l (10.4 to 59.2 nmol/l) to 20.4 nmol/l (13.2 to 33.8 nmol/l)). Changes in self reported exposure to secondhand smoke were consistent with the changes in cotinine concentrations. Reporting any respiratory symptom declined significantly in the Republic (down 16.7%, - 26.1% to - 7.3%) but not in Northern Ireland (0% difference, - 32.7% to 32.7%). After adjustment for confounding, respiratory symptoms declined significantly more in the Republic than in Northern Ireland and the decline in cotinine concentration was twice as great.Conclusion The smoke-free law in the Republic of Ireland protects non-smoking bar workers from exposure to secondhand smoke.
