Key health themes and reporting of numerical cigarette–waterpipe equivalence in online news articles reporting on waterpipe tobacco smoking: A content analysis

摘要

Introduction: There is anecdotal evidence that health messages interpreted from waterpipe tobacco smoking (WTS) research are inconsistent, such as comparing the health effects of one WTS session with that of 100 cigarettes. This study aimed to identify key health themes about WTS discussed by online news media, and how numerical cigarette–waterpipe equivalence (CWE) was being interpreted.
