Objective To understand the status of tobacco advertising exposure and its influencing factors among middle school students in Hangzhou and provide the basis for reducing tobacco advertising exposure. Methods A stratified cluster sampling method was used to select 5 primary and secondary schools in Hangzhou and 2 secondary vocational schools. A questionnaire survey was conducted among 3 593 students in school. Results 90.7% of the respondents reported seeing tobacco advertisements and tobacco sponsorships in the past 30 days and 28.9% reported seeing tobacco promotions. The stores that sell cigarettes are the most commonly found tobacco ads (79.6%), followed by television (57.9%), outdoor billboards (49.6%) and the Internet (41.4%). The risk factors of tobacco advertising acceptance were smoking status (OR = 4.588), family smoking status (OR = 1.222), smoking status of peers (OR = 1.500), parents’ attitudes towards children smoking (OR = 1.897) (OR = 2.400), tobacco advertising and sponsor exposure intensity (OR = 2.287) and tobacco promotion exposure intensity (OR = 2.949). Conclusion Adolescents are exposed by tobacco advertising, sponsorship and promotion. They should create a smoke-free atmosphere at home, school and society to keep adolescents away from the harmful effects of tobacco.
