Olympic City Part Of The Public / Workplace Tobacco Control Effect Evaluation

ObjectiveTo evaluate the effectiveness of tobacco-free policies and interventions on public places and workplaces in the six mainland China Olympic cities;To provide scientific base for developing Chinese tobacco-free laws and policies.Methods4 taxi companies,58 hospitals and 19 CDCs(centers for disease control and prevention)were conveniently sampled in Beijing;4 taxi companies,20 hospitality venues and 10 restaurants were also conveniently sampled in each city as Tianjin, Shanghai,Shenyang,Qinhuangdao and Qingdao.For each of these public places/work places,objects of the survey were also conveniently sampled,but at least including one leader or owner,and were surveyed by questionnaires on their knowledge of and attitudes towards tobacco hazards,smoking and second hand smoke information and so on.Tobacco-free environments and SHS exposure was assessed by observation and measuring the level of particulate matters less than 2.5 microns in diameter(PM_2.5) using TSI Sidepak.Qualitative research was used to acquire information about the attitudes towards banning smoking completely in public places/work places in Qinhuangdao.The collected data was entered by professional data company,was analyzed by SPSS13.0.Result1) knowledge of and attitudes towards tobacco hazards The object of survey in taxi companies and hospitality venues has got significant changes on knowledge of and attitudes towards tobacco hazards;Most of objects in hospitals and CDCs have acquired the knowledge of tobacco hazards and greatly agree with towards tobacco hazards;The object of restaurants who think that 'SHS causes heart' diseases reduced greatly(Pearsonχ²=6.46,p=0.01 ),but their knowledge of and attitudes towards other tobacco hazards has got no significant changes.2) smoking and secondhand smoke M ost of objects don't change their smoking behaviors but workers of hospitality venues and taxi drivers,most of objects' secondhand smoke state has got good and significant changes but objects in restaurants.3) attitudes towards tobacco-free public places There are more managers of taxi companies who support to ban smoking in the taxi company than the past;Most leaders of hospitals and CDCs also support to ban smoking in their work places and would like to develop tobacco-free hospital or CDC;Managers towards tobacco-free hospitality venue or restaurant has got good and significant changes.Both managers and workers didn't support to ban smoking completely in public places,because they thought that people's behavior donn't change in a while and there are no tobacco-free national laws/policies.4) tobacco-free environments Compared with the past,the taxi and the hospitality venue tobacco-free environments have got significant changes;hospitals and CDCs' tobacco-free environments in Beijing have been keeping well or got changes as the taxi;restaurants in 5 cities only keeping well.5) bans of smoking and its effectiveness Ojects in taxi companies obey the ban better than the past;There are more objects know the bans in hospitals,CDCs, hospitality venues and restaurants than the past,but only in CDCs and hospitality venues it have got good effectiveness.6) PM_2.5 monitoring 'T test' tells us there are no significant changes in the average indoor PM_2.5 level and the outdoor PM_2.5 level in hospitals,CDCs,and restaurants, and 'covariance analysis' tells us that there are indeed no significant changes in the average indoor PM_2.5 level either.But 't test' tells us there are significant changes on the average indoor PM_2.5 level by hospitality venues' monitoring data,'covariance analysis' tells us that there are significant statistical reduces on the average indoor PM_2.5 level too(F=8.28,P=0.005).ConclusionTobacco-flee policies and interventions keep well or change greatly their knowledge of and attitudes towards tobacco hazards;It donn't change most objects' smoking behavior,but effectively reduces their chances of exposure to SHS;It make managers or leaders' attitudes turn to the good side on banning smoking;it keep well or change greatly tobacco-free environments in the intervened public places/work places,and there are more objects know banns of smoking,but not all of public places' objects obey the rule well for tobacco-free policies and interventions; it effectively reduces the average indoor PM_2.5 level in hospitality venues.
