Abstract:

Objective To analyse the perceived environment system of tobacco experimentation among junior middle school students in Shanghai. Methods Cross-sectional study was conducted among 12 413 students from 23 junior middle schools in Shanghai by stratified cluster sampling. The conditions of tobacco experimentation and perceived environment system of these students were surveyed. The potential factors in perceived environment system were assessed using Logistic regression analysis, and their impact on tobacco experimentation was analysed. Results The rate of tobacco experimentation in junior middle school students was 6.8%. The rate of tobacco experimentation of boy students was 9.3%, which was significantly higher than that of girl students (4.6%)(P<0.001). Multivariate regression analysis indicated that 7 factors in perceived environment system had impact on tobacco experimentation in junior middle school students, which included high smoking press from peers (OR=4.12, 95%CI: 3.50-4.84), more exposure to cigarette smoke in family (OR=1.46, 95%CI: 1.38-1.96), more exposure to smoking from media (OR=1.40, 95%CI:1.19-1.65) and high tobacco use acceptance (OR=1.37, 95%CI:1.17-1.60). Conclusion Factors in perceived environment system are closely related to tobacco experimentation in junior middle school students, which should be attached great importance in tobacco control among junior middle school students.
