Abstract P186: Cigarette Smoking and Exposure to Passive Smoking in Chinese Adult Population: The China Metabolic Risk Factor Study
Objective: Cigarette smoking remains a major public health concern in China. We estimated the prevalence of cigarette smoking and the extent of passive exposure to cigarette smoking in the general population in China.
Methods: We conducted a cross-sectional survey in a nationally representative sample of 98,658 Chinese adults aged ≥18 years in 2010. Information on active cigarette smoking and passive exposure to cigarette smoking was obtained by trained interviewers using a standard questionnaire. Prevalence of cigarette smoking was calculated by weighting sampling factors derived from China population census 2010 data to obtain national estimates.
Results: The prevalence of current cigarette smoking was much higher in men (53.3%) than in women (2.5%). Prevalence followed an inverted U-shape with age in men (46.2% in 18-29 years, 56.9% in 30-39 years, 59.2% in 40-49 years, 58.5% in 50-59 years, 50.7% in 60-69 years, and 40.1% in ≥70 years) but increased with age in women (1.1% in 18-29 years, 1.8% in 30-39 years, 2.2% in 40-49 years, 3.1% in 50-59 years, 4.4% in 60-69 years, and 5.8% in ≥70 years). The prevalence was slightly higher in rural (53.6%) compared to urban residents (52.5%) in men whereas it was lower in rural (2.4%) relative to urban residents (2.7%) in women. Among non-smokers, 43.3% of men and 45.3% of women reported exposure to passive smoking at home or in their workplace. Based on our findings, 270.0 million Chinese men and 12.2 million Chinese women aged ≥18 years were current cigarette smokers, 102.5 million non-smoking men and 216.9 million non-smoking women were exposed to passive smoking at home or in working place.
Conclusion: The high prevalence of cigarette smoking in Chinese men indicates an urgent need for smoking prevention and cessation efforts. The large number of Chinese men and women exposed to passive smoking in their workplace argues for prohibition of cigarette smoking in the work environment in China.
