Richard Pito, a professor at Oxford University, recently told the annual meeting of British Cancer Research in Birmingham that although smoking is a global problem, it is particularly prominent in some countries. Perhaps developing countries are most affected by smoking. Some countries are making anti-smoking laws, but the proportion of smokers in some countries is rising.
At present, 5 million adults die of smoking every year in the world, and 30 million new smokers. Pito said that if 20 million new smokers insist on smoking, half of them will die because of this hobby, and the number of tobacco-related deaths worldwide will exceed100000 every year.
Peter Boyle, head of the International Institute for Cancer Research, said that countries should take more effective measures to persuade smokers to quit smoking, restrict tobacco advertising and implement effective anti-smoking laws.
The researchers of China Hypertension Investigation Team collected the distribution of smoking and other risk factors in 199 1 year from the people over 40 years old sampled in 169 and 87 1, and then interviewed the respondents again from 1999 to 2000. The number of deaths caused by smoking in 2005 was calculated by statistical method.
The results show that most smokers are men with low education. There is an obvious dose-effect relationship between death and the number of cigarettes smoked each year. The more you smoke, the higher the death rate. Researchers estimate that in 2005, about 673,000 people died of smoking-related diseases in China, including 538,000 men and 0/34,000 women. Among the causes of death related to smoking, there are about 268,000 cases of cancer, 65,438+046,000 cases of cardiovascular diseases and 67,000 cases of respiratory diseases.
The research conclusion shows that smoking is one of the main causes of death in China. It is necessary to strengthen smoking cessation education and action to reduce smoking-related diseases and deaths.
