Secondhand smoke exposure and susceptibility to initiating cigarette smoking among never-smoking students in selected African countries: Findings from the Global Youth Tobacco Survey

摘要

Background. Exposure to secondhand smoke (SHS) causes premature death and illness in non-smokers. We examined SHS exposure at home and in public places, as well as susceptibility to initiate cigarette smoking among never cigarette smokers. We used 2006-2011 Global Youth Tobacco Survey (GYTS) data from 29 African countries (56,967 students).
