Table A1.

Smoking prevalence (%) (over 15 years of age) in four large-scale tobacco sampling surveys in China.

Sex	Year
	1984	1996	2002	2010
Male	62.0	63.0	57.4	52.9
Female	7.0	3.8	2.6	2.4

Notes: For 1984, the results are derived from a 0.5‰ sample tobacco survey based on the third national census in 29 provinces in China. For 1996 and beyond, the results are derived from the Surveillance on Behavioural Risk Factors in China supported by the World Bank’s Loan Project. In total, 145 disease surveillance points were established in 30 provinces in China and three-stage stratified random samples with good representativeness were used.
