The first global study into the effects of passive smoking has found that second hand smoke causes 600,000 deaths every year - this is more than 1% of all deaths.
The first global study into the effects of passive smoking has found that second hand smoke causes 600,000 deaths every year - this is more than 1% of all deaths. One-third of those killed are children, often exposed to smoke at home.
The study, in 192 countries, found that passive smoking is particularly dangerous for children, said to be at higher risk of sudden infant death syndrome, pneumonia and asthma. Passive smoking can cause heart disease, respiratory illness and lung cancer.
The report estimates that 165,000 children die of smoke-related respiratory infections, mostly in South East Asia and in Africa. It said that this group was more exposed to passive smoking than any other group, principally in their own homes. The mix of infectious diseases and second-hand smoke is a deadly combination. As well as being at higher risk of a series of respiratory conditions, the lungs of children who breathe in passive smoke may also develop more slowly than children who grow up in smoke-free homes.
The report further said that worldwide, 40% of children, 33% of non-smoking men and 35% non-smoking women were exposed to second-hand smoke in 2004. This exposure was estimated to have caused 379,000 deaths from heart disease, 165,000 from lower respiratory infections, 36,900 from asthma and 21,400 from lung cancer.
According to the study, the highest numbers of people exposed to second-hand smoke are in Europe and Asia and the lowest rates of exposure were in the Americas, the Eastern Mediterranean and Africa.
The research also revealed that passive smoking had a large impact on women, killing about 281,000 worldwide. This is due to the fact that in many parts of the world, the study suggests, women are at least 50% more likely to be exposed to second-hand smoke than men.
