ABSTRACT
Objective To understand tobacco use rate and explore the factors associated with tobacco use in middle school students in China.Methods A self-administered questionnaire survey was conducted among 155 117 eligible middle students selected through multi-stage stratified cluster sampling from 31 provinces of China.The questionnaire consists of the following topics:tobacco use and cessation,passive smoking,access to tobacco products,tobacco control and tobacco advertisement,and knowledge about and attitudes to tobacco.Software SAS 9.3 was used for sample weighting and data analysis.Results Current tobacco use rate was 6.9％ in middle school students in China.The rate was higher in boys (11.2％) than in girls (2.2％),and in rural area (7.8％) than in urban area (4.8％).Students in western area had the highest tobacco use rate (10.3％),followed by the students in middle area (6.4％),and the rate in students in eastern area was lowest (4.5％).Parent smoking (especially mother smoking),friend smoking,teacher smoking,pocket money for a week ＞ 20 yuan,tobacco advertisement or promotion,passive smoking,misconception of tobacco addiction,active attitude to smoking behavior were the risk factors for tobacco use.Conclusions Smoking rate in boys in China was higher than the average global level.A comprehensive intervention strategy by Framework Convention on Tobacco Control should be used to reduce tobacco use in adolescents,including health education,increasing cigarette price,banning tobacco advertisement and promotion,and smoke-free legislation.

ABSTRACT
Objective To evaluate the impact of cigarette excise tax up-regulation on the retail price of cigarettes in 2015.Methods Nominal and real price of selected cigarette varieties were calculated with data from Tobacco Retail Price Monitoring Project,which was conducted in 10 cities of China from 2013 to 2015.The trend of the cigarette prices changing was analyzed with annual data.Results A total of 352 varieties of cigarettes were surveyed during the three years.The nominal price of these cigarettes did not change significantly from 2013 to 2014.Compared with nominal price of 2014,the price of 286 varieties increased and the price of 10 most popular varieties increased from 0.6％ to 7.4％ after cigarette excise tax increased,but the actual prices had both rise and fall compared with 2013.Conclusions Cigarette excise tax raise in 2015 had influence on the retail price of cigarettes.But the increase in retail price was very limited,if factors including inflation and purchasing power are taken into consideration.Therefore,the influence of 2015 cigarette excise tax raise on tobacco control needs further evaluation.

ABSTRACT
Objective To identify the levels of exposure to second-hand smoking (SHS)among Chinese adults living in the urban areas and their knowledge on the risks of SHS,to support for the Smoke-free policy.Methods Data from the Global Adult Tobacco Survey (GATS) and the International Tobacco Control Policy Evaluation China Survey (ITC China Survey) was analyzed and SAS was used to calculate the rates and 95％ CI.Results In the two surveys,less than 40％ of the respondents reported that their workplaces had completely stopped smoking.Participants who reported that they had seen people smoking at various public places with different rates,also they could reflect the levels to SHS exposure.Restaurants were the venue with the heaviest overall exposure (83.4％-95.6％),followed by the workplace (53.3％-84.0％).Exposure was low in health facilities,schools and public transport venues.In the GATS survey,60.6％ smokers and 68.5％ non-smokers believed that SHS could cause lung cancer,but only one-third of the participants believed that SHS could cause heart diseases in adults.Participants in the ITC China survey reported a comparatively higher level of awareness on the harm of SHS,but only 58.2％ smokers believed that SHS could cause heart diseases in adults.Overall,data from the ITC China survey showed that participants' support for a comprehensive smoke-free policy in schools,health-related facilities,government buildings and in taxi were high (over 70％).However,the proportion of participants supporting comprehensive smoking-free policy at workplaces (50.9％-60.9％) was relatively low.Conclusion The proportion of indoor workplaces with complete smoking ban was low in urban areas but levels to SHS exposure were high.People's awareness of harms related to SHS and their attitude on setting up a comprehensive smoke-free workplace need to be improved.
ABSTRACT
Objective To evaluate the effectiveness of voluntary smoke-free policies in Beijing.Methods With convenient sampling,91 restaurants and 85 restaurants were respectively selected before and after the initiation on voluntarily banning smoking in public eating and drinking places by the catering industry in Beijing,and including a follow-up surveillance on 23 restaurants.Field investigation on smoke-free rules and PM2.5 monitoring in and outside of these restaurants were conducted.Results There were no statistic differences among the proportion of restaurants with different smoking policies(?2=2.60,P=0.28).Univariate analysis showed that the indoor PM2.5 level was positively related with the outdoor PM2.5 level(?=0.51,t=7.01,P
