Electronic cigarette related topics with conflicting arguments in Chinese newspapers

Abstract

INTRODUCTION While debates on e-cigarettes are mainly conducted in scientific fora, media are the most accessible information source for the public, shaping their perceptions of health issues. This study is the first to examine e-cigarette related topics with conflicting arguments presented in Chinese newspapers. METHODS The Chinese terms for ‘e-cigarettes’ were searched in a widely used Chinese news database Wisenews. Content analysis of the full text of 639 news articles was conducted to identify topics with conflicting arguments and examine whether the dominant argument in each topic changed across four time periods from 2004 to 2019. RESULTS Twelve e-cigarette related topics with conflicting arguments were identified. The most frequently reported topic was health impact of e-cigarettes, followed by impact of secondhand aerosol exposure, smoking cessation, relative health impact of e-cigarettes compared to cigarettes, and e-cigarette policies outside China. At the same time, the price was the least frequently reported topic. Overall, negative arguments outnumbered positive arguments in the study period. The dominant arguments within many topics changed across time periods; however, within the topics of relative health impact of e-cigarettes compared to cigarettes, taste/flavor, and economic prospects of the industry, positive arguments were more frequently reported in almost all periods. Within the topics of addiction, policies in China, and policies outside China, negative arguments were more frequently reported in virtually all periods. CONCLUSIONS Though overall the dominant argument about e-cigarettes and health was ‘e-cigarettes are harmful’, in the early time periods, e-cigarettes were reported as ‘harmless’ or even ‘healthy’. As China began to regulate e-cigarettes, the reporting on e-cigarettes more frequently included the ‘e-cigarettes are harmful’ argument. The consistent, more frequent reporting of ‘good e-cigarette taste/ flavor’ has the potential to attract young people to e-cigarette products. The increased reporting on policies unfavorable to e-cigarettes aligned with the growing number of regulations restricting e-cigarettes.
