Current smoking prevalence and SHS exposure prevalence by gender and age in 1984, 1996 and 2002 in China.

Note: athe Chinese population was 1,299,880,000, reported by the National Bureau of Statistics; the population by gender and age groups were estimated from the WHO WPR-B dataset with a proportion of 82% (total Chinese population/total WHO WPR-B population in 2004) because they were not available from the bureau’s datasets; The numbers in each of the first four columns may not add up to the corresponding subtotals or totals due to rounding up during calculation.
b LCD, lung cancer deaths, estimated from the WHO WPR-B dataset;
c IHD, ischaemic heart disease death, estimated from the WHO WPR-B dataset;
d,e data from a national survey in 1984 [36], in 1996 [35] and in 2002 [38].

注：中国总人口为1299880000，数据由国家统计局（National Bureau of Statistics）发布；因国家统计局未提供分性别与年龄组的人口数据，故基于2004年中国总人口与世界卫生组织西太平洋区域数据集（WHO WPR-B）的总人口占比82%，以此估算得到分性别与年龄组的人口数据；由于计算过程中进行了四舍五入，前四列的各项数值之和可能与对应小计或总计存在偏差。
b 肺癌死亡数（LCD, lung cancer deaths），由WHO WPR-B数据集估算得到；
c 缺血性心脏病死亡数（IHD, ischaemic heart disease death），由WHO WPR-B数据集估算得到；
d、e 数据分别来自1984年[36]、1996年[35]及2002年[38]的全国性调查。
