[目的]了解餐饮单位控烟状况及室内烟雾浓度,为加强公共场所及工作场所控烟措施提供依据。[方法]2008年10月,在青岛市城区随机抽取36家餐饮单位(16家为控烟干预组,20家为对照组),调查控烟状况、工作人员和管理者控烟态度,观察和检测烟雾(PM2.5颗粒物)浓度。[结果]观察干预组16家、对照组20家。有禁烟标志者所占比例,干预组为50.00%,对照组为20.00%(P>0.05);有吸烟区或烟区划分者所占比例,干预组为37.50%,对照组为25.00%(P>0.05);调查从业人员487人(干预组240人、对照组247人),吸烟率分别为13.75%、12.96%(P>0.05);如果单位有禁止吸烟规定会要求顾客灭烟者所占比例,2组分别为67.50%、71.66%(P>0.05);认为酒店禁烟不会影响生意者所占比例,2组分别为60.83%、60.73%(P>0.05)。调查酒店餐馆管理者36人(干预组16人、对照组20人),愿意开展无烟单位创建活动者所占比例,2组分别为93.75%、80.00%(P>0.05);如果单位有禁止吸烟规定会要求顾客灭烟者所占比例,2组分别为93.75%、90.00%(P>0.05);认为禁烟不会影响生意者所占比例,2组分别为75.00%、40.00%(P<0.05);室内空气PM2.5浓度(μg/m3),干预组、对照组分别为119.08±17.56、227.62±45.04(P<0.01);室外空气PM2.5浓度,干预组、对照组分别为89.62±5.91、128.56±22.23(P<0.01)。[结论]干预后员工对控烟的认识明显提高,室内烟草烟雾浓度降低。
[Objective] To understand the status of tobacco control and indoor smoke concentration in catering establishments and provide basis for strengthening tobacco control measures in public places and in the workplace. [Methods] In October 2008, 36 catering units were randomly selected in urban areas of Qingdao (16 were tobacco control intervention groups and 20 were control groups). Tobacco control status, staff and managers’ attitude towards tobacco control were investigated, and smoke and smoke PM2.5 particulate) concentration. [Results] The intervention group of 16, control group of 20. The proportions of those with no smoking signs were 50.00% in the intervention group and 20.00% in the control group (P> 0.05). The proportions of smoking or smoking areas were 37.50% in the intervention group and 25.00% in the control group (P > 0.05). There were 487 surveyed workers (240 in the intervention group and 247 in the control group). The smoking rates were 13.75% and 12.96% respectively (P> 0.05). If the unit had no smoking regulations, (67.50%, 71.66%, respectively) in the two groups (P> 0.05). It was considered that the smoking ban in hotels did not affect the proportion of businesspeople in the two groups, 60.83% and 60.73% respectively (P> 0.05). Investigate the hotel restaurant managers 36 (intervention group of 16 people, control group of 20 people), willing to smoke-free units to create activities accounted for the proportion of two groups were 93.75%, 80.00% (P> 0.05); if the unit is prohibited The smoking regulations would require the customers to eliminate the proportion of the smokers, 93.75%, 90.00% (P> 0.05) in the two groups respectively; smoking is not considered to affect the proportion of businesspeople in the two groups, 75.00% and 40.00% respectively (P < 0.05). The concentration of PM2.5 in indoor air (μg / m3) was 119.08 ± 17.56 and 227.62 ± 45.04 respectively in the intervention group and the control group (P <0.01). The concentration of PM2.5 in outdoor air was 89.62 ± 5.91,128.56 ± 22.23 (P <0.01). [Conclusion] The staff awareness of tobacco control increased significantly after intervention, indoor smoke concentration decreased.
