Objective To understand the status of tobacco epidemic among adults in Zhejiang province in 2013.Methods A total of 2 779 residents aged 15-69 years from 15 counties were selected using stratified multi-stage cluster sampling method and surveyed by face to face interview to complete questionnaire.Results The current smoking prevalence was 25.62％ among the adults 15-69 years old in Zhejiang province,50.88％ among males and 0.78％ among females.The daily smoking prevalence was 21.85％;40.56％ of the current daily smokers smoked within 30 minutes after waking;95.19％ of current smokers were not willing to quit;64.04％ of all respondents reported someone smoked in their own homes;67.48％ smokers thought they would continue to smoke even if the price of tobacco rises;21.09％ of all respondents saw tobacco AD at shops and on TV;42.00％ of people were aware that smoking could cause stroke,heart attack and lung cancer;89.69％ smokers still believed that low-tar cigarettes were less harmful than regular cigarettes;73.92％ of people agreed with completely no-smoking in public places.Conclusions Male smoking prevalence in Zhejiang remains at a high level,coupled with low rate of quitting,second hand smoke exposure remains a serious issue in household,low awareness of the harms of smoking for people,suggesting that the task of controlling smoking needs to be strengthened.

Objective To evaluate the strength of tobacco control at or below county-level governments of Zhejiang Province,to explore the strategies and measures on tobacco control,and promote a smoke-free government.Methods By multistage stratified random sampling method,12 government ageucies were selected in 4 counties.The information of tobacco control strength and smoke-free environment creation was collected by interview and field observation,and the scores were calculated by using the percentage assignment method.An intercept suuvey was carried out in four counties and there were 405 civil servants under investigation.The data were analyzed by frequency statistic and correlation analysis.Results The smoking rate of civil servants was 17.8％,and the secondhand smoking rate was 61.9％;84.7％ of civil servants adnmitted the harm of smoking and 96.8％ admitted the harm of secondhand smoking.Support for forbidding the cigarette advertisements was highest and increasing the cigarette price was the weakest.The scores of smoke-free environment creation of project counties showed that the average score was 50.60,Zhuji and Luqiao got a maximum score of 57.14,Haiyan got a minimum score of 42.86.The scores of tobacco control strength showed that the average score was 82.35,Zhuji got a maximum score of 92.16,followed by Luqiao,Jiande and Haiyan counties,82.35,80.39 and 74.51 respectively.The scores of tobacco control strength,include policy,political will,capacity,and tobacco control efforts were the highest in Zhuji county.The results of correlation analysis showed that the total score of tobacco control strength had significant association with the score of smoke-free environment creation,smoking rate of civil servants,and approval rate of anti smoking in public places (P＜0.05).Conclusion The overall situation of tobacco control strength at or below county-level governments of Zhejiang province is good,but there is a relative shortage of smoke-free environment creation.Civil servants master the knowledge related to tobacco and support tobacco control policy.We should further promote the construction of smoke-free government.More effective smoking control measures should be conducted in order to raise the strength of tobacco control and finally implement the tobacco control legislation.

Objective To understand the prevalence of tobacco use among college students in different populations by sex,age and major,and to provide evidence for smoking control and health decision.Methods A total of 4 638 college students selected in 21 colleges through stratified multi-stage cluster sampling from Zhejiang Province were surveyed by using questionnaire analysis.Indicators such as tried smoking,current smoking,and secondhand smoke exposure,etc.,were calculated by weight on age proportions from the numbers of college students in Zhejiang.Results The prevalence of tried smoking and currcut smoking among college students were 29.72％ and 10.57％,respectively.The prevalence of tried smoking was 46.52％ for men,18.25％ for women;28.57％ for undergraduate,31.53％ for junior college;the prevalence of current smoking was 18.86％ for men,3.86％ for women;8.88％ for undergraduate,13.23％ for junior college students.The snoking rate in college students increased with age,the group of ≥21 Years was the highest (37.87％,16.09％).The lowest level of smoking was medical student (21.76％,2.19％).The prevalence of secondhand smoke exposure in outdoor and indoor places,and dormitory among students were 65.49％,60.33％,and 23.66％,respectively.In the past 30 days,college students have seen tobacco advertisement (47.38％),smoking scenes (60.20％),and got tobacco related gifts (10.40％),free tobacco products (8.93％);college students have seen information about tobacco control (60.50％),cigarette pack warning labels (58.45％),and learned the tobacco knowledge in class in the past 12 months (14.03％).Conclusion Current prevalence of smoking in college students in Zhejiang province remained at a high level,the rate of secondhand smoke exposure is high and in college students there was lack of tobacco control education in class.The results indicated that the policy about tobacco control in school was not enough and the task of health promotion should be taken more arduously.

Objective To explore the determinants of willingness to quit smoking among pre-pregnancy male smokers, and to provide evidence for smoking cessation strategies. Methods An intercept survey was carried out in four cities in Zhejiang, and there were 552 pre-pregnancy male smokers from 1401 newly wedded couples under investigation. Result The pre-pregnancy male smoking rate was 39.82%, and only 6.88%of pre-pregnancy male smokers were categorized as highly nicotine-dependent. The rate of recent willingness to quit smoking was 50.54%, and reasons for quitting were as follows:a planned pregnancy (62.50%), an example for children (47.70%), and objections from family members (45.22%). The tobacco knowledge among pre-pregnancy male smokers is relatively poor, only 49.64% of smokers were aware 8 points in 11 questions; 88.75% of smoker's wives supported their husband to quit smoking. The associated factors of smoking cessation include: tobacco knowledge (OR=0.38), health self-assessment well (OR=1.90), wife's willing for husband to quit smoking (OR=2.87). Conclusion Compared to ordinary people, the proportion of intention to quit smoking was higher in pre-pregnancy male smokers. To strengthen health education and make wife initiating in husband's quitting programs would be more effective.

Objective: To investigate the prevalence of cigarette and electronic cigarette ( e-cigarette ) use among adults in Zhejiang Province, so as to provide insights into tobacco control. Methods : Thirty study sites were randomly sampled from Zhejiang Province in 2020 using a multi-stage stratified random sampling method, and permanent residents at ages of 15 to 69 years were selected as study subjects. A questionnaire was designed based on the questionnaire for the China Adult Tobacco Survey to collect subjects' demographic characteristics, cigarette and e-cigarette use, smoking cessation and exposure to secondhand smoke ( SHS ). The weighted prevalence of smoking, current smoking, current e-cigarette smoking, smoking cessation and exposure to SHS was estimated based on the Seventh National Population Census in 2020. Results : A total of 19 200 questionnaires were recovered, and 19 180 were valid, with an effective recovery rate of 99.90%. The respondents had a mean age of ( 50.30±12.90 ) years, with a male to female ratio of 1∶1.06 and an urban/rural population ratio of 1∶1.31. Among all the respondents, there were 6 033 smokers ( 31.45% ), 4 163 current smokers ( 21.70% ), 201 current e-cigarette users ( 1.05% ), 146 cigarette and e-cigarette dual users ( 0.76% ), 1 870 respondents quitting smoking ( 31.00% of smokers ) and 7 189 respondents with exposure to SHS ( 47.87% of non-smokers ). The weighted prevalence of smoking, current e-cigarette use, cigarette and e-cigarette dual uses, smoking cessation and exposure to SHS was 20.49%, 1.34%, 0.94%, 29.56% and 49.53% in Zhejiang Province, respectively, and the prevalence of current smoking, current e-cigarette use, cigarette and e-cigarette dual uses and exposure to SHS was 40.39%, 2.39%, 1.86% and 55.31% among males and 0.35%, 0.28%, <0.01% and 46.02% among females, respectively. The highest prevalence of current smoking was seen among respondents at ages of 55 to 64 years ( 24.24% ), while the highest prevalence of current e-cigarette use and cigarette and e-cigarette dual uses was seen in adults at ages of 25 to 34 years ( 2.18% and 1.58% ). Conclusions The prevalence of current e-cigarette use was higher among adults in Zhejiang Province in 2020 than the nationwide level in China. The prevalence of cigarette use was lower among adults in Zhejiang Province in 2020 than the nationwide level in China; however, improving the management of tobacco control in public places and the capacity building of smoking cessation services is still required to reduce the use of cigarettes and e-cigarettes.

Objective : To investigate the establishment of smoke-free environments in medical and healthcare institutions in Zhejiang Province, so as to provide the evidence for improving the implementation of the tobacco control policy in medical and healthcare institutions. Methods: Health administrative sectors and public health institutions at provincial, city and county levels, secondary and tertiary medical institutions, and community health service/township health centers in Zhejiang Province were enrolled. The status of institutional establishment of smoke-free environments was investigated through concealed photography and consulting medical service guides by the assigned the third-party professional investigation company in 2021. The layout of smoke-free environments and indoor smoking were assessed according to the Criteria for Scoring Smoking-free Medical and Healthcare Institutions. Results: Totally 547 medical and healthcare institutions were enrolled in this undercover investigation, including 102 health administrative sectors, 209 public health institutions, 146 secondary and tertiary medical institutions, and 90 community health service/township health centers. The gross mean scores of establishment of smoke-free environments were 83.41±12.19 among all medical and healthcare institutions, 82.02±10.73, 85.56±9.70 and 83.18±12.59 among province-, city- and county-level medical and healthcare institutions, respectively, and the gross mean scores of establishment of smoke-free environments were 82.60±12.27, 85.79±10.74, 80.89±13.85, 82.27±11.62 scores among health administrative sectors, public health institutions, secondary and tertiary medical institutions and community health service/township health centers, respectively. There were 315 institutions with no smoking signs at entrances (57.59%), 255 institutions posting no smoking signs ( 46.62% ), 245 institutions assigning two and more types of health education materials for tobacco control ( 44.79% ), 110 institutions with outdoor smoking areas ( 51.16% ), 66 secondary and tertiary medical institutions with smoking cessation clinics ( 45.20% ) and 354 institutions with carpet smoking bans in indoor places ( 64.72% ). Conclusions The overall establishment of smoke-free environments is satisfactory among medical and healthcare institutions in Zhejiang Province. Nevertheless, improving the coverage of no smoking signs and health education of tobacco control, promoting the standardized construction of smoking cessation clinics and establishing a long-action tobacco control mechanism are still needed.

Objective: To evaluate the effect of a tobacco control intervention for college students under the advocate-promoting model, and to provide evidence for methods to improve smoking control and health decisions. Methods: Four colleges were selected from the list of colleges that participated in a survey of college student tobacco use in Zhejiang Province in 2015, and we conducted a tobacco control intervention with them under the advocate-promoting model for two years. A total of 1 007 students were selected using a random sampling method and surveyed before intervention, and 991 students were selected using a random sampling method and surveyed after the intervention. A chi-square test was used to compare the differences between tobacco use, second-hand smoke exposure, and tobacco knowledge among students before and after the intervention. Results: After the tobacco control intervention, the attempted smoking rate among students in the four colleges dropped from 34.36% to 22.30%, the current smoking rate dropped from 12.12% to 7.87%, the second-hand smoke exposure rate decreased from 75.47% to 70.53%, the difference was statistically significant (χ²=37.73, 9.99, 6.18, P<0.05). After intervention, the proportion of students who had seen tobacco advertisements in the past 30 days decreased from 60.38% to 54.4%, the proportion of students who "saw smoking scenes in video media" decreased from 25.02% to 19.58%, and the proportion of students who "learned smoking control knowledge in class" increased from 14.20% to 18.16%, the difference was statistically significant (χ²=7.08, 8.55, 5.79, P<0.05). Conclusion The advocate-promoting model of "advocacy alliance" can help colleges to establish a smoke-free campus environment and improve college students’ tobacco knowledge and reduce their attempted and current smoking rates.

Objective To describe the prevalence of tobacco use among teenagers in different populations by sex and grades at school,and to provide evidence for the development of smoking control and health promotion programs.Methods A total of 4 797 teenagers selected from 36 schools through stratified multi-stage cluster sampling in Zhejiang province and were surveyed by using a questionnaire with 3 886 eligible ones for analysis.Indicators as tried smoking,current smoking,and secondhand smoke exposure,etc.,were calculated by weight on age proportions from the numbers of juniors in Zhejiang province.Results Prevalence rates of tried smoking and current smoking among teenagers were 10.91％ and 2.07％,respectively.7.72％ of the juniors were susceptible to future tobacco use.The prevalence rates of tried smoking were 15.65％ for boys and 5.58％ for girls,12.13％ in rural and 9.24％ in urban areas.Students from the 9th grade showed the highest rate (15.15％) while the 7th graders appeared the lowest level of susceptibility to future tobacco use (5.22％).The highest level of current smoking was seen in the group of "weekly allowance more than 30 Yuan,from parents"(4.07％).The prevalence of secondhand exposure to smoke in outdoor and indoor places,public transport,or at home were 57.60％,54.45％,46.97％,and 43.16％,respectively,among the teenagers.3 071 juniors (77.33％) saw the smoking scenes in the past 30 days but only 1 367 juniors (28.30％) were aware of the basic knowledge on tobaccos in class,in the past 12 months.Conclusions There were juniors who tried to smoke or were current smokers.The rate of secondhand exposure to smoking was high.A large number of the juniors were lack of education on knowledge related to tobacco control,in the classroom.It was important to promote and publicize the knowledge on tobacco so as to reduce the number of teenagers who were susceptible to future tobacco use.

Objective To describe the prevalence rates of smoking,quitting and passive smoking in different populations on their status of education,occupation and geographic distribution.Methods A total of 13 408 residents aged 15-69 from 45 counties through stratified multi-stage cluster sampling from Zhejiang province were selected and surveyed,using questionnaires.Data from 13 326 subjects were used for analysis.Indicators as smoking,current smoking,and secondhand smoke exposure,etc.,were calculated by weight on age proportions from the 2010 census.Results Among the adults aged 15 years and older,there were an estimated number of 12.90 million (29.59％) smokers,with 9.99 million (22.92％) current smokers,8.45 million (19.38％) daily current smokers.The prevalence rates of smoking were 41.18％ for men,3.69％ for women,with 45-54 year-old group the highest (51.66％) for men while the group of 65-69 year-olds was the highest (4.62％) in women.The overall rate of quitting was 22.56％.40.19％ of the smokers had thought about quitting,with the main means as self-restriction (87.59％) in conducting the behavior of smoking cessation.Among those non-smokers at age 15 or older,it was estimated that 67.90％ (22.77 million) of them had been exposed to secondhand smoke.SHS exposure was the highest in the indoor workplace (62.84％),among all the venues.Knowledge on tobacco among residents seemed to be relatively poor,with only 31.52％ of the population were aware that smoking could cause serious three diseases (stoke,heart disease,and lung cancer).34.04％ of the population were aware that secondhand smoking could cause all the three diseases (heart disease,lung disease,and lung cancer).Conclusion Current prevalence of smoking in males in Zhejiang province remained at a high level,indicating that the publicity programs on the knowledge of smoking tobacco was not strong enough and the task of control smoking should be taken more arduously.

Objective: To evaluate the effectiveness of a text message for smoking cessation among _{male smokers before their wives}' _pregnancy, and to provide evidence for smoking cessation strategies. Methods: A prospective observational study was conducted in four cities of Zhejiang province from April to October 2016. A total of 552 male smokers were assessed using data from structured questionnaires at baseline and were followed up at 1 and 6 months. A total of 307 participants were provided a text message _{(SMS) for smoking cessation intervention, along with wives}' _{involvement in husbands}' _quitting programs. The intervention group was compared with the control group without intervention. Outcomes were self-reported 7-day point prevalence abstinence rates at 1-month and 6-months follow up. Results: In the intervention group, the proportion of participants who self-reported to be healthy reduced from 26.4% to 15.3% at 1-month follow-up and increased to 21.8% at 6-month follow-up; in the control group, it was reduced from 19.2% to 11.4% at 1-month follow-up, and increased to 20.4% at 6-month follow-up. The 7-day point prevalence abstinence rate of the intervention group at 1 and 6 months were higher than that of the control group: at 1-month follow-up, 13.0% vs. 8.2%; at 6-month follow-up, 16.3% vs. 8.2%, respectively. Compared to the control group, the intervention group considered "determination" as the most important support (61.9% at 1 month, 60.9% at 6 months); "addiction cycle" was the main barrier (47.2% at 1 month, 48.9% at 6 months), and they were less influenced by other smokers (8.1% at 1 month, 5.2% at 6 months). Conclusion SMS smoking cessation intervention, along with wife's involvement in husband's quitting programs had a positive effect on the quitting rates.
