The number of daily smokers and deaths from tobacco has increased worldwide since 1990, despite progress made in most countries since then, researchers warned Thursday that the war on tobacco is far from to be won.
One in four men and one woman on 20 were daily 2015 smokers, close to a billion, according to the report Global Burden of Diseases, established by a consortium of hundreds of scientists. This is a significant decrease in the proportion of daily smokers compared to the previous 25 1990, where one in three men and one woman on 12 smoked each day.
But despite this improvement, the number of smokers has increased from 870 million in 1990 to more than 930 million, due to global population growth. And the number of deaths attributed to tobacco, more than 6,4 million in 2015 increased by 4,7% during the same period.
Mortality could increase even more as leading tobacco companies aggressively target new markets, particularly in developing countries, warns the report in the medical journal The Lancet.
Smoking accounts for one in ten deaths worldwide, half of them in only four countries: China, India, the United States and Russia. Together with Indonesia, Bangladesh, the Philippines, Japan, Brazil and Germany, they account for two-thirds of global tobacco consumption.
"Smoking remains the second risk factor for early death and disability" after high blood pressure, according to lead author Emmanuela Gakidou of the Institute for Measurement and Evaluation of Health at the University of Washington. Some countries have seen a sharp reduction in smoking with a combination of higher taxes, education campaigns, warnings and stop-smoking programs.
Brazil, among the leaders over the 25 years surveyed, went from 29% daily smokers to 12% in men and 19% to 8% smokers. Indonesia, Bangladesh, and the Philippines - with 47%, 38%, and 35% of smokers, respectively - have not made any progress between 1990 and 2015.
According to the World Health Organization (WHO), the number of men and women smokers in sub-Saharan Africa will increase by 50% by 2025 compared to 2010. Future mortality in low- and middle-income countries will likely be " huge ", notes a British specialist, John Britton, in a commentary in The Lancet.
Half of daily smokers, half a billion, can be expected to die prematurely unless they quit smoking, he adds.
