Objectives: To understand the smoking behavior and tobacco knowledge of Chinese adolescents and their relationship with the mass media. Methods: According to the Global Youth and Tobacco Survey Core Questionnaire designed and provided by the Centers for Disease Control and Prevention, 11,957 middle school students from 200 secondary schools in Tianjin, Shandong, Chongqing and Guangdong provinces and cities were withdrawn by self-assessment. Results: 22.3% of the respondents had tried smoking before, and the prevalence of smoking was 4.9%. The awareness of the harmful effects of smoking and passive smoking had a negative impact on smoking behavior (OR = 1.74 and 1.58). The smoking in the mass media and social activities (OR = 0.80 and 0.85), smoking cinema image, cigarette trademark, cigarette advertisement and publicity were the risk factors for smoking (OR = 1.59-1.68). Conclusion: The mass media has an important influence on smoking behavior and tobacco knowledge among adolescents, and a comprehensive policy system should be established for youth to control tobacco use.
