Emerging tobacco hazards in China : 1. Retrospective proportional mortality study of one million deaths.
Objective To assess the hazards at an early phase of the growing epidemic of deaths from tobacco in China.
Design Smoking habits before 1980 (obtained from family or other informants) of 0.7 million adults who had died of neoplastic, respiratory, or vascular causes were compared with those of a reference group of 0.2 2 million who had died of other causes.
Setting 24 urban and 74 rural areas of China.
Subjects One million people who had died during 1986-8 and whose families could be interviewed.
Main outcome measures Tobacco attributable mortality in middle or old age from neoplastic, respiratory, or vascular disease.
Results Among male smokers aged 35-69 there was a 51% (SE 2) excess of neoplastic deaths, a 31% (2) excess of respiratory deaths, and a 15% (2) excess of vascular deaths.
All three excesses were significant (P<0.0001).
Among male smokers aged >=70 there was a 39% (3) excess of neoplastic deaths, a (2) excess of respiratory deaths, and a 6% (2) excess of vascular deaths.
Fewer women smoked, but those who did had tobacco attributable risks of lung cancer and respiratory disease about the same as men.
For both sexes, the lung cancer rates at ages 35-69 were about three times as great in smokers as in non-smokers, but because the rates among non-smokers in different parts of China varied widely the absolute excesses of lung cancer in smokers also varied. (...)
