Objective: To describe the prevalence of e-cigarette use among adolescent in Zhejiang province, and to analyze its distribution of different genders and school types to provide evidence for controlling the use of e-cigarette among adolescent. Methods: A total of 7 663 students from 60 middle schools through stratified multi-stage cluster sampling methods from Zhejiang province were surveyed by using questionnaire. Indicators as tried to use e-cigarette rate, current e-cigarette using rate, and other indicators were collected. All data were weighted by age proportions of adolescent in Zhejiang. Results: The prevalence of tried to use and current using e-cigarettes among middle school students were 6.99% and 1.45%, respectively; and there were 4.19% juniors who were susceptibility to future e-cigarette use. The rate of tied to use e-cigarette, current using e-cigarette and susceptibility to future e-cigarette use were higher in boys than in girls. The rate of current using e-cigarette was 2.07% for rural and 0.48% for urban. Technical secondary school students had the highest rate of tried to use e-cigarette and susceptibility to future e-cigarette use (13.53%, 6.91%). Junior school students (2.96%) had the lowest level of susceptibility to future tobacco use. The rate of tried e-cigarette use and current e-cigarette use and susceptibility to future e-cigarette use were higher in the group of "One of students' parents was smoker" (8.63%, 2.19%, 5.23%). The highest rate of current smoking was found in the group of "Weekly allowance more than 50 Yuan" (10.02%, 2.54%, 6.29%). Compared to technical secondary school students, senior school student (OR=0.57) and junior school students (OR=0.45) were less likely to try to use e-cigarette. Students whose weekly allowance were less than 20 Yuan were less likely to try to use e-cigarette (OR=0.49). Students who were boys (OR=5.44) and one of their parents was smoker (OR=1.59) were more likely to try to use e-cigarette. Conclusions: There were middle school students with tried e-cigarette use and current e-cigarette use, especially in technical secondary schools. The prevalence of e-cigarette using among middle school students increased with age. It is important to further spread of e-cigarette knowledge widely and deeply, and reduce the susceptible population of adolescents using e-cigarettes.

The development of an evaluation index system on health information on the internet using Delphi method / 预防医学

Objective To develop an evaluation index system on health information on the internet using Delphi method. Methods The index system on health information on the internet was drown up and then two rounds of 11 experts' questionnaire consultation were conducted using Delphi method to determine the index system. Results Of 11 experts, the mean age was 48.55±6.79, and 91.67％ of experts had high professional titles and had been working for average (23.64±10.10) years. The altive coefficient for the first and the second hound consultation was 91.67％ and 100.00％ respectively. The average coefficient of specialists authority was 0.75. After two round consultations, Kendalf's concordance coefficients were 0.39 (P<0.01) and 0.51 (P <0.01) , respectively. After two rounds of Delphi, the index system includes 3 from first-level indicators and 15 from secondary-level indicators. Conclusion Experts' representativeness, enthusiasm and professionalism brought to a consensus in developing an evaluation index system to be used in monitoring health information on the internet.

An investigation on smoke-free environment and smoking statusat or below county-level governments / 预防医学

Objective To learn the smoke-free environment and smoking status at or below county-level governments of Zhejiang Province, and to promote a smoke-free government.Methods By multi-stage random sampling method, 4 cities were selected in Zhejiang Province, then 4 counties were selected in 4 cities, finally12 governments were selected in 4 counties.With the methods of field observation,interview and questionnaire survey,smoke-free environment and smoking behavior , tobacco related knowledge of civil servants were investigated.Results A total of 12 governments and 405 civil servants were investigated.The smoke-free environment of 12 governments were relatively well.The total smoking rate of civil servants was 17.78%, and the highest was 26.67% in Jiande City, and the lowest were 9.00% in Zhuji City.For the civil servants ,male(26.62%), aged 50-(40.74%),divorced or widowed(40.00%),graduation of technical secondary school (33.33%),cadre of section rank(57.14%),above 20 years' work(28.81%),smoking anywhere at home(50.00%), smoking in certain areas at work(22.95%)were significantly higher.The rate of cognition on the hazards of smoking was lower among the smokers than that of non-smokers (P<0.05).The rate of agreement on MPOWER tobacco control strategies and smoking bans in public places were lower among the smokers than that of non-smokers (P<0.05).Non-conditional logistic regression analysis showed that age of 30-39(OR=9.87,95%CI:1.45-67.29),50-(OR=9.87,95%CI:1.45-67.29), smoking anywhere at home(OR=12.28,95%CI:2.95-51.18),and smoking in certain areas at home(OR=6.57,95%CI:3.07-14.08) may be the risk factors about smoking behavior.Conclusion The situation of smoking control at or below county-level governments in Zhejiang Province was good, and smoking rates has declined.But tobacco related knowledge and behavior of civil servants were relatively insufficient.Aiming at the problems found in the investigation, it is necessary to strengthen education on smoking control among civil servants, and to promote a smoke-free government.
