ObjectiveTo understand the current status of smoking attempt among adolescents in Jiading District of Shanghai and to explore the influencing factors so as to provide suggestions for further intervention and control of tobacco smoking among adolescents.
MethodsA total of 3 745 students from grade one to grade three from seven junior high school in Jiading District， Shanghai， were selected to participate in the survey by stratified cluster random sampling method. Anonymous internet questionnaire survey was conducted and the survey data， including main demographic information and smoking attempt， was analyzed by binary logistic regression test. Smoking attempt was defined as the teenagers had smoked at least one puff prior to the time of questionnaire survey.
ResultsA total of 3 630 valid questionnaires were collected and the rate was 96.9%（3 630/3 745）. Overall 4.4%（158/3 630） of participants had smoking attempt. The results of binary logistic regression test showed that compared with women， men had higher risk of attempted smoking （P<0.05）. Compared with registered residence in Shanghai， the risk of smoking behavior was higher among adolescents who were not registered residence in Shanghai （P<0.05）. Smoking behavior among family members， classmates and friends were risk factors for adolescents to attempt smoking （P<0.05）. When the number of family smoker was higher than 2， the risk of young students trying to smoke was significantly higher （P<0.05）. Compared with the students who believed smoking was harmful to adolescents' health， it was a risk factor for those who considered trying to smoke might be harmful or harmless to try smoking （P<0.05）.
ConclusionSmoking control in Jiading District schools has achieved some success， and the proportion of teenagers trying to smoke is low. However， further enhancement of smoking control among young people is still in need and we should devote more attention on male adolescents with non-Shanghai residence registration， and family smoke-free environment.
