Objectives. We estimated the prevalence of cigarette smokingand the extent of environmental tobacco smoke exposure (ETS)in the general population in China.
Methods. A cross-sectional survey was conducted on a nationallyrepresentative sample of 15540 Chinese adults aged 3574years in 20002001. Information on cigarette smoking wasobtained by trained interviewers using a standard questionnaire.
Results. The prevalence of current cigarette smoking was muchhigher among men (60.2%) than among women (6.9%). Among nonsmokers,12.1% of men and 51.3% of women reported exposure to ETS athome, and 26.7% of men and 26.2% of women reported exposureto ETS in their workplaces. On the basis of our findings, 147358000Chinese men and 15895000 Chinese women aged 3574 yearswere current cigarette smokers, 8658000 men and 108402000 womenwere exposed to ETS at home, and 19072000 men and 55372000 womenwere exposed to ETS in their workplaces.
Conclusions. The high prevalence of cigarette smoking and environmentaltobacco smoke exposure in the Chinese population indicates anurgent need for smoking prevention and cessation efforts.
